Description
Technical field
The present invention relates to common lathe saddle feed arrangement, more particularly to a kind of worm gear feed device.
Background technology
The knife rest of lathe used at present is that immovable support is driven with pedestal by small leading screw, and manually or Mobile rotating is realized
Feed, since when processing slender rod piece, workpiece is cantilever design, radial cutting force can cause workpiece moderate finite deformation, workpiece
It is constantly made a concession to the direction for reducing load, influences the precision of machined surface.Therefore, it is mostly used at present to bar when processing elongate rod
Part centering is withstood by tailstock centre and increases its rigidity.
Invention content
The present invention provides a kind of worm gear feed device.Technical problem to be solved：First, reducing radial in process
Error caused by power；Second is that the device has degree of precision and scale is uniform；Third, realization device self-locking.
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions：
A kind of worm gear feed device, including three slide bars, notch disk, guide rail disk, worm gear and worm screw；Notch disk is inlaid in snail
It is interference fitted in the annulus of wheel and with worm gear, is furnished with several threaded holes along contact circumference, is fastenedly connected with screw, notch back-end disk
Axle journal stretch out worm gear rear end face；From circumference to the center of circle to being provided with three uniformly distributed arc grooves on the front end face of notch disk
Mouthful, the central border line of arc-shaped slot is spiral of Archimedes；Radially be provided on the end face of guide rail disk backwards three it is recessed
The same side of slot, three grooves is overlapped with the diameter of guide rail disk, and the angle of the extended line of adjacent two edges is 120 °；It is sliding
Bar side is boss, has a cylindrical boss in the middle part of the other side；Three slide bars are inlaid in respectively in three grooves of guide rail disk；
The end face of guide rail disk backwards contacts to form positive and concentric fit with face with the front end face of notch disk by face, and makes three
Cylindrical boss in the middle part of the slide bar other side is respectively placed in three arc-shaped slots on notch disk front end face, the cylinder of slide bar
It protrusion can be along the arc-shaped slot free movement of notch disk；Worm gear is meshed with worm screw, and the rotation angle of worm screw is fed with slide bar
Distance ratio under the action of spiral of Archimedes is fixed constant.
Three cutters, while machined part are clamped respectively using three slide bars in the present invention, this reduces due to adding
Unilateral radial load makes part elastic deformation generate the mismachining tolerance for allowing knife phenomenon to bring during work；In notch disk and guide rail disk
Under common effect of contraction, the rotation of worm gear is become the linear motion of three slide bars；To keep the scale of dial uniform, that is,
The ratio between the rotation angle of worm screw and the feed distance of slide bar are constant, so the contour line of the notch of notch disk uses Archimedes
Helix；Due to using Worm Wheel System, worm gear transmission ratio is higher, keeps feed accuracy high, to can also realize institute
State the self-locking function of device.
Due to the adoption of the above technical scheme, the present invention has the following advantages that compared with prior art：
Present invention feeding scale is uniform and feed accuracy is high；Radial load is to accessory size when can reduce processing elongate rod
It influences；It being capable of realization device self-locking.

Specific implementation mode
For the ease of the understanding of those skilled in the art, this is described further with specific embodiment below in conjunction with the accompanying drawings
Invention：
The present invention a kind of worm gear feed device, as shown in figs. 1 to 6, including three slide bars 1, notch disk 2, guide rail disk 3,
Worm gear 4 and worm screw 5；As shown in figs. 34, notch disk 2 is inlaid in the annulus of worm gear 4 and is interference fitted with worm gear 4, along contact
Circumference is furnished with several threaded holes, is fastenedly connected with screw 6, prevents worm gear 4 from generating axially opposite and radial position with notch disk 2
It moves；The axle journal 10 of 2 rear end of notch disk stretches out the rear end face of worm gear 4, and axle journal is coupled with external equipment indirectly by bearing；Such as Fig. 5
Shown in~6, from circumference to the center of circle to being provided with three uniformly distributed arc-shaped slots 8 on the front end face of notch disk 2, arc-shaped slot 8
Central border line is spiral of Archimedes；As shown in Fig. 1,2 and 6, three are radially provided on the end face of guide rail disk 3 backwards
The same side of groove 9, three grooves 9 is overlapped with the diameter of guide rail disk 3, and the angle of the extended line of adjacent two edges is
120°；As shown in fig. 6,1 side of slide bar is boss, there is a cylindrical boss 7 in the middle part of the other side；As shown in Fig. 1,5 and 6, three
A slide bar 1 is inlaid in respectively 9 in three grooves of guide rail disk 3；The end face of guide rail disk 3 backwards and the front end face of notch disk 2 pass through
Face contacts to form positive and concentric fit with face, when being connected with external equipment, realizes the fixation of relative position, this is matched
Conjunction mode is similar to taper roll bearing；And before so that the cylindrical boss 7 in the middle part of three 1 other sides of slide bar is respectively placed in notch disk 2
In three arc-shaped slots 8 on end face, the cylindrical boss 7 of slide bar 1 can be along 9 free movement of arc-shaped slot of notch disk 2；Such as figure
Shown in 1~5, worm gear 4 is meshed with worm screw 5, and the rotation angle of worm screw 5 and 4 feeding distance of slide bar are in spiral of Archimedes
Under the action of ratio be fixed constant.
In the use of the present invention, there be a cylindrical boss positioning surface and external equipment shown in Fig. 4 in 3 other end of guide rail disk
Positioning, since in the course of work, guide rail disk 3 is static, therefore it is equipped with three planes shown in Fig. 2 as clamping face, and adjacent
The extended line angle in two clamping faces is 60 °, and external equipment realizes the fixation to guide rail disk 3 to flat grip.It is feeding
When, by rotary worm 5 counterclockwise, worm gear 4 is driven to rotate, and then notch disk 2 rotates, boss and the notch phase of three slide bars 1
Interaction generates movement, and guide rail disk 3 is static, and generates constraint to the direction of motion of three slide bars 1, leads to three slide bars 1 simultaneously
Radial feed movement is done, the amount of feeding is reached, stop rotating worm screw 5, and realizes current location self-locking automatically.In withdrawing, pass through
Worm screw 5 is rotated clockwise, worm gear 4 is driven to rotate, and then notch disk 2 reversely rotates, boss and the notch interaction of slide bar 1 are produced
Raw movement generates constraint since guide rail disk 3 is static to slide bar 1, and three slide bars 1 far from workpiece, realize withdrawing simultaneously.This feeding dress
It sets in entire range, under the characteristic effect of the spiral of Archimedes of 2 notch of notch disk, the rotation angle and cunning of worm screw 5
The ratio of 1 feeding distance of bar is fixed constant, realizes that scale dial scale is uniform, realizes the easy to operate of feed arrangement.
