The risers of the rotor plate 2050 are hinged to the hinge 2060, and the second damper assembly 20202 is mounted to the cross-plate of the rotor plate 2050.

In a specific embodiment, the heel unit 20 further includes a vibration sensor and a vibration control module, the vibration sensor is used for measuring the vibration amplitude of the position where the heel module 2020 is attached to the workpiece 60, and in particular, the vibration sensor may be mounted at the position of the first contact block 20205 or the second contact block 20209.

The vibration control module controls the first vibration reduction assembly 20201 and the second vibration reduction assembly 20202 to work, the vibration sensor is connected with the vibration control module, at least one of the first vibration reduction assembly 20201 and the second vibration reduction assembly 20202 is connected with the vibration control module, and preferably, the first vibration reduction assembly 20201 and the second vibration reduction assembly 20202 are both connected with the vibration control module. Specifically, the vibration control module, the vibration sensor, the first vibration damping assembly 20201 and the second vibration damping assembly 20202 may be connected by a wired or wireless connection manner to implement signal transmission. When the vibration control module receives the vibration sensor amplitude data exceeding the preset value, the vibration of the workpiece 60 to be processed is reduced by adjusting the positions of the first movable end and the second movable end.

Specifically, when the vibration sensor includes a first sensor for monitoring the vibration at the position of the first vibration damping assembly 20201 and a second sensor for monitoring the vibration at the position of the second vibration damping assembly 20202, the vibration control module controls the first vibration damping assembly 20201 to reduce the pressure of the workpiece 60 when the monitored pressure value of the first sensor exceeds the first pressure value; when the first sensor monitor pressure value is lower than the second pressure value, the vibration control module controls the first vibration damping assembly 20201 to increase the pressure of the workpiece 60, and the first pressure value is greater than the second pressure value. When the second sensor monitored pressure value exceeds the third pressure value, the vibration control module controls the second vibration reduction assembly 20202 to reduce the pressure of the workpiece 60; when the second sensor monitored pressure value is lower than the fourth pressure value, the vibration control module controls the second vibration reduction assembly 20202 to increase the pressure of the workpiece 60, and the third pressure value is greater than the fourth pressure value.

For example, when the vibration of the first contact block 20205 or the second contact block 20209 exceeds a preset amplitude, the vibration control module pressurizes the inside of the first adjusting component 20203 and the second adjusting component 202011, so that the acting force acting on the workpiece 60 to be processed is increased when the first contact block 20205 or the second contact block 20209 stretches out, until the amplitude measured by the vibration sensor is smaller than a preset value, the first contact block 20205 or the second contact block 20209 is stopped to be driven to move, that is, the follow-up knife unit 20 provided by the application is matched with the knife module for use, closed-loop control is performed according to the vibration sensor by adopting an air pressure self-adapting corresponding device, when the vibration is increased, the vibration control module controls the air pressure, and the jump is restrained, so that the metal workpiece can be always kept in effective fit with the knife module, and the influence caused by deflection change generated by processing is reduced.

Specifically, a plurality of cutter modules may be provided, and the plurality of cutter modules are circumferentially distributed around the workpiece. As shown in fig. 11 and 12, specifically, the machining center is provided with two tool modules, namely, a tool module 10a and a tool module 10b, which are horizontally arranged on the left and right sides of the rotary workpiece.

As shown in fig. 13 to 17, the machine tool system for reinforcing a surface of a material further includes a third vibration reduction unit 30, two third vibration reduction units 30 are provided, the two third vibration reduction units 30 are respectively attached to two opposite sides of the workpiece 60, specifically, the third vibration reduction units 30 are symmetrically provided at the top end and the bottom end of the workpiece 60, and the force application directions of the two tool assemblies to the workpiece 60 extend in the horizontal direction.

The tool unit 10 further comprises a support module 1022, the support module 1022 being movable parallel to the centre line of revolution of the workpiece 60. The supporting module 1022 is formed by fixing the cutter module, the third vibration reduction unit 30 and the cutter following unit 20 together and connecting them to the supporting plate 1023, and the supporting module 1022 is made of a metal material with better rigidity so as to ensure that the cutter module, the third vibration reduction unit and the cutter following unit are not deformed during processing.

In a specific embodiment, the third vibration reduction unit 30 includes a mounting seat 301, a displacement sensor, and a displacement adjustment module 302 connected to the displacement sensor for adjusting the force applied by the mounting seat 301 and the workpiece 60, where the displacement sensor is used for measuring the amplitude of the mounting seat 301, and specifically, when the amplitude is greater than 0.1mm, the displacement adjustment module 302 performs adjustment. Of course, the amplitude is not limited to the above-described case when the displacement adjustment module 302 performs adjustment of the mount 301 according to the actual situation.

The displacement sensor is in signal connection with the displacement adjusting module 302, the mounting seat 301 is provided with a limiting groove 303 attached to the workpiece 60, and specifically, the limiting groove 303 may be a V-shaped groove opening towards the direction of the workpiece 60. The displacement adjustment module 302 may be a pneumatic cylinder or a hydraulically controlled adjustment device.

In particular, the control structure and motion control components of the displacement adjustment module 302 may be integrated on one control unit.

The position of the limit groove 303 of the mounting seat 301 is preferably made of polytetrafluoroethylene, which has excellent self-lubricating performance and moderate hardness, and can not scratch the surface of the workpiece 60 during processing.

The third vibration reduction units 30 comprise two, and the two third vibration reduction units 30 are respectively attached to two opposite ends of the workpiece 60. In one embodiment, two third vibration reduction units 30 are symmetrically disposed at left and right ends of the workpiece 60. In another embodiment, two third vibration reduction units 30 are symmetrically disposed at the top and bottom ends of the workpiece 60.

During processing, the displacement adjusting module 302 enables the vibration of the revolving body to be reduced by controlling the two mounting seats 301 of the butt clamp, and meanwhile, the displacement sensor senses real-time force application loading and feeds back to the displacement adjusting module 302. The application uses the closed-loop controlled cutter unit 10 and the third vibration reduction unit 30, and the pressure sensor 104 and the displacement sensor are used for detecting and feeding back to the control structure, so that the cutter unit 10 can be accurately adjusted and responded in real time according to the change of the processing process, and the workpiece processing and clamping modes are changed, thereby effectively inhibiting the vibration of the workpiece 60 and the cutter unit 10, ensuring that the fitting degree of the workpiece 60 is better, forming continuous and stable surface hardening, effectively inhibiting the jump quantity and the axial straightness deviation caused by the vibration lines generated by uneven stress and deflection deformation of the slender shaft when the slender shaft is processed by a single-side cutter, namely reducing the problem of vibration of the workpiece metal material in the processing process of the gradient nanostructure in the processing process.

The limiting groove 303 of the third vibration reduction unit 30 is made of polytetrafluoroethylene, the rest parts are made of quenching tool steel, and the displacement adjustment module 302 is made of a hydraulic device. When the vibration amplitude is larger than 0.001mm, the displacement adjusting module 302 enables the limiting groove 303 to be tightly clamped at the position to be processed through a hydraulic device, the vibration quantity of the limiting groove 303 is reduced, and the vibration quantity is kept within 0.001 mm. Specifically, when the control structure receives the increase of the applied force sensed by the displacement sensor so that the applied force exceeds the maximum acceptable value of the workpiece 60, the third vibration reduction unit 30 is controlled to move away from the workpiece 60 until the applied force sensed by the displacement sensor is within the acceptable range of the workpiece 60, and the third vibration reduction unit 30 stops moving. When the control structure receives the increase of the applied force sensed by the displacement sensor so that the applied force is lower than the minimum acceptable value of the workpiece 60, the third vibration reduction unit 30 is controlled to move towards the workpiece 60 until the applied force sensed by the displacement sensor is within the acceptable range of the workpiece 60, and the third vibration reduction unit 30 stops moving.

At the time of specific assembly, the cutter unit 10 is integrally mounted on the pallet 1023 through the support module 1022. Preferably, the support modules 1022 are slidable in a direction perpendicular to the direction of motion of the pallet 1023 to guide the relative position of the cutter unit 10. The third vibration reduction unit 30 is installed in two installation holes provided in front and rear of the support module 1022.

In the present invention, the direction of the force applied by the tool unit 10 to the workpiece 60 and the direction of the force applied by the third vibration damping unit 30 to the workpiece 60 are coplanar, so that the vibration of the workpiece 60 is further reduced.

In another embodiment, the two tool units 10 apply force in a direction that is higher than the center line of revolution of the workpiece 60 and lower than the center line of revolution of the workpiece 60.

In one machining mode, the two third vibration reduction units 30 are arranged up and down, the two third vibration reduction units 30 are arranged in a centering and opposite mode, the cutter modules are arranged left and right, and the two cutter modules are eccentrically opposite, namely the force application direction of the cutter modules to a workpiece is isolated from the rotation center line of the workpiece. When the metal material with high strength is processed, the applied load is high, so that the spherical cutter head can roll smoothly. The traditional centering and jacking mode is abandoned by the two cutter modules, and eccentric arrangement is adopted, namely the left cutter head is adjusted by 0.1mm upwards along the Z axis by using the cutter position adjusting cutter module, the right cutter head is adjusted by-0.1 mm upwards along the Z axis by using the cutter position adjusting cutter module, and vice versa.

The tool unit 10 may be used for machining a workpiece 60 of a body of revolution.

The workpiece 60 may be a metal piece.

In one embodiment, the same workpiece 60 may be machined using a single tool unit 10.

In another embodiment, the same workpiece 60 is machined simultaneously by using the front and rear cutter units 10, so that the force for flexibly deforming the workpiece 60 is effectively counteracted. When the to-be-machined piece 60 of the metal material is subjected to nanocrystallization, the cutter units 10 positioned at the left end and the right end apply pressure to the surface of the metal material from the two ends and roll along with the workpiece, and meanwhile, the cutter units 10 are adjusted according to the vibration condition of the to-be-machined piece 60, so that the vibration is stabilized in a reasonable range.

Through integrating the third damping unit 30 on the cutter unit 10, when the to-be-machined workpiece 60 is machined, the two cutter units 10 are oppositely arranged to clamp the to-be-machined workpiece 60, the two third damping units 30 are respectively attached to two opposite sides of the to-be-machined workpiece 60, namely, in the machining process of the to-be-machined workpiece 60, the two oppositely arranged third damping units 30 are used for limiting the force applied to the to-be-machined workpiece 60, so that vibration in the machining process of the to-be-machined workpiece 60 is reduced, and the machining quality of the revolving body is improved.

As shown in fig. 18 to 22, the cutter module includes a cutter assembly, a pressure sensor 104, a power assembly 105, a pressure adjustment assembly 106, and a motion control assembly, the pressure sensor 104 being for sensing the pressure of the cutter assembly. The power assembly 105 provides machining pressure to the cutter assembly during machining. Specifically, the power assembly 105 may be a hydraulic assembly.

The pressure regulating assembly 106 is connected to the cutter assembly to provide a pneumatic module process pressure, the pressure response rate of the pressure regulating assembly 106 applied to the cutter assembly being greater than the power assembly 105. In a particular assembly, the pressure sensor 104 is mounted to the housing of the power assembly 105 by a first fastening module 1013, which may be a threaded fastener.

The electromagnetic force comprises two electromagnetic members which are matched in a repulsive manner, the relative position is adjusted by adjusting the relative acting force of the two electromagnetic members, and one electromagnetic member can be directly connected with the power assembly 105.

The pressure adjusting component 106 is an air pressure module, and a push rod 1015 of the air pressure module is connected with the housing of the power component 105. The air pressure module comprises a shell and a push rod 1015 arranged on the shell, and the output end of the push rod 1015 acts on one end of the power component 105 far away from the pressure sensor 104. The shell is internally provided with a cavity for installing the piston at the end part of the push rod 1015, the shell is provided with two gas quick connectors communicated with the cavity, and the two gas quick connectors are respectively a gas pressure first quick connector 1010 and a gas pressure second quick connector 1011, so that the shell is connected with a gas source to realize gas inlet and gas exhaust of the cavity.

The pressure sensor 104 and the pressure adjusting component 106 are positioned on two opposite sides of the power component 105, and a guiding module for guiding the movement direction of the pressure adjusting component 106 is arranged between the outer shell of the pressure adjusting component 106 and the outer shell of the power component 105.

The cutter modules are arranged at two opposite sides of the workpiece 60, and the force application directions of the cutter modules to the workpiece 60 are coincident.

Specifically, the guide module may be a guide post 107, one of the housing of the pressure adjusting assembly 106 and the housing of the power assembly 105 is fixedly connected to the guide post 107, and the other is slidably connected to the guide post 107.

In the operating state of the cutter unit 10, both the power assembly 105 and the pressure sensor 104 module are in a state of pressurizing the cutter assembly.

The pressure sensor 104, the power component 105 and the pressure adjusting component 106 are all connected with the action control component, and specifically, signal transmission can be realized through a wire electrical connection or a wireless communication mode. When the motion control assembly receives that the pressure value of the pressure sensor 104 rises above a first preset value within a preset time, the motion control assembly controls the pressure adjustment assembly 106 to depressurize the tool assembly, i.e., reduce the force that the tool assembly acts on the workpiece 60.

Specifically, the motion control component controls the pressure adjustment component 106 to reduce the pressure of the cutter component until the motion control component receives the pressure value of the pressure sensor 104 and stops the motion of the pressure adjustment component 106 when the rising value of the pressure value is smaller than the first preset value within the preset time. The power assembly 105 may be deactivated or the power assembly 105 may simultaneously depressurize the cutter assembly while the motion control assembly controls the pressure regulating assembly 106 to depressurize the cutter assembly.

When the motion control assembly receives that the pressure value of the pressure sensor 104 falls beyond a second preset value within a preset time, the motion control assembly controls the pressure adjustment assembly 106 to boost the pressure of the tool assembly, i.e., increase the force of the tool assembly on the workpiece 60 to be machined. Specifically, the motion control component controls the pressure adjustment component 106 to boost the pressure of the cutter component, and the motion control component stops the motion of the pressure adjustment component 106 when the pressure value of the pressure sensor 104 is reduced to be less than a second preset value within a preset time. The power assembly 105 may be deactivated or the power assembly 105 may simultaneously boost the cutter assembly while the motion control assembly controls the pressure regulating assembly 106 to boost the cutter assembly. Wherein the work piece 60 may be a quenched steel gradient hardened work piece.

In particular, the tool assembly may be a conventional tool for machining a workpiece. Wherein the first preset value and the second preset value are determined according to the tool assembly and the workpiece processing bearing pressure. The time period of the preset time is set according to the requirement.

In one embodiment, when the motion control assembly receives that the pressure sensor 104 increases above a first preset value of a preset pressure range value for a preset time, the motion control assembly controls the pressure adjustment assembly 106 to depressurize the cutter assembly; when the motion control assembly receives a second preset value that the pressure sensor 104 has exceeded the preset pressure range value at the preset time, the motion control assembly controls the pressure adjustment assembly 106 to boost the pressure of the cutter assembly. The preset pressure range value is a pressure value required by the cutter component when the workpiece is normally processed.

In another embodiment, when the motion control assembly receives that the pressure sensor 104 increases above the preset pressure range value by a first preset value at a preset time, the motion control assembly controls the pressure regulating assembly 106 and the power assembly 105 to simultaneously depressurize the cutter assembly; when the motion control assembly receives a second preset value that the pressure sensor 104 has exceeded the preset pressure range value at the preset time pressure drop, the motion control assembly controls the pressure regulating assembly 106 and the power assembly 105 to simultaneously boost the cutter assembly. At this time, the cutter assembly may be simultaneously pressure regulated by the pressure regulating assembly 106 and the power assembly 105.

The cutter modules are arranged in pairs, and the two cutter modules are arranged in opposite tops. The direction of application of force to the workpiece 60 extends in the horizontal direction. The force application directions of the two tool modules to the workpiece 60 may be arranged in line, and at this time, the line connecting the force application directions of the two tool modules to the workpiece 60 may pass through the rotation center of the workpiece 60 or be arranged offset from the rotation center of the workpiece 60.

When the appearance of the workpiece suddenly changes during processing and the pressure is required to be increased immediately, the pressure regulating component 106 controls the pressure regulating component 106 to quickly perform a pressurizing reaction according to the operation result of the action control component, so that the cutter component works under the required pressure as soon as possible. Specifically, when the workpiece shape suddenly changes during processing and the pressure is required to be reduced immediately, the pressure adjusting component 106 controls the air pressure module to rapidly reduce the pressure according to the operation result until the action control component receives that the pressure sensor 104 is located in the preset pressure range, and the action control component controls the air pressure module to stop acting. The action control assembly controls the air pressure module to rapidly decompress and boost the cutter assembly, and the air pressure adjusting speed is high, so that the air pressure adjusting device can rapidly respond and timely adjust the pressure of the position of the cutter assembly to be within a preset pressure range, thereby realizing high response and real-time following.
