Description

Multi-cutter gear shaping mechanism

Technical Field

The utility model relates to a gear machining equipment technical field, in particular to multitool formula gear shaping mechanism.

Background

In the field of numerical control machines, the machining of tooth surfaces of internal and external gears or racks by a generating method or a forming method using a slotting cutter is called gear shaping. The gear shaping mechanism utilizes the up-and-down reciprocating motion of a gear shaping cutter to process the tooth surface. From the principle analysis of the gear shaping process, the gear shaping cutter is equivalent to a pair of cylindrical gears with mutually parallel axes which are meshed. The pinion cutter is essentially a gear ground with a front and back clearance and having a cutting edge. The gear shaping mechanism generally involves the following movements: 1. cutting movement, up and down reciprocating movement of the pinion cutter. 2. The tooth dividing generating movement is to keep the correct meshing relationship between the gear shaping cutter and the workpiece. The gear shaping cutter reciprocates once, and the arc length of the workpiece rotating on the reference circle relative to the cutter is the circumferential feeding amount in processing, so the meshing process of the cutter and the workpiece is the circumferential feeding process. 3. And radial feeding movement, wherein the gear shaping cutter has radial feeding amount fr for gradually cutting to the full tooth depth during gear shaping. 4. The cutter back-off moves, and when the pinion cutter reciprocates up and down, the downward direction is the cutting stroke. In order to avoid the tool scratching the machined tooth surface and to reduce the wear of the tool teeth, the work piece is driven by the table to exit the cutting zone for a distance (radial direction) while the shaper cutter is moved upwards. And when the pinion cutter works, the workbench is restored to the original position.

In patent literature, there is the utility model of grant bulletin number CN207723622U, the name is improved generation gear shaping machine, discloses an improved generation gear shaping machine, including motor, aircraft nose mechanism and gear shaping mechanism, the motor sets up in aircraft nose mechanism below, and the axle of motor sets up with aircraft nose mechanism relatively, and aircraft nose mechanism includes a plurality of pivot devices of being connected with the main shaft rotation, the regulation lead screw of being connected with the main shaft, it is connected with gear shaping mechanism rotation to adjust the lead screw.

However, in the prior art and patent documents, when the slotting cutter is used for processing internal teeth with different specifications, the slotting cutter needs to be replaced with cutters with different specifications for many times, a large amount of time is wasted for dismounting and setting the slotting cutter, and the processing efficiency is not improved. Under the normal condition, only one slotting cutter can be fixed with the piston rod through the chuck, and only one specification tooth surface of the internal tooth can be subjected to slotting machining at one time, so that the production efficiency is low, and the requirement of mass high-efficiency production cannot be met.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the multi-cutter gear shaping mechanism comprises a square shell 1, a gear shaping cutter 2 located at a corresponding position on the side surface of the square shell 1, a disc 3 located at the bottom of the square shell 1 and connected with the square shell 1, and a first cylinder 4 connected with the disc 3 through a transmission shaft. In a specific embodiment, the multi-blade gear shaping mechanism is located on the working platform, and the first cylinder 4 is driven by a servo motor. The first cylinder 4 drives the disc 3 to rotate, and the disc 3 is connected with the square shell 1 to drive the square shell 1 to rotate. The working principle of the first cylinder 4 driving rotation is similar to that of a steam locomotive connecting rod, the first cylinder 4 drives a first transmission shaft 41 to move linearly, one end of a second transmission shaft 42 is hinged with the first transmission shaft 41, and the other end of the second transmission shaft is fixed on the periphery of the disc 3 to drive the disc to rotate. The square casing 1 is a cylindrical casing with square upper and lower bottom surfaces.

In a specific embodiment, as shown in fig. 3, the multiple-blade gear shaping mechanism further comprises a second cylinder 5 located inside the square housing and connected through an adjusting screw 51, the disc 3 has a through hole, and a main shaft 52 of the second cylinder 5 passes through the through hole of the disc 3. When the multi-cutter gear shaping mechanism works, firstly, the gear shaping cutter 2 is utilized to reciprocate the tooth surface up and down, and after the gear shaping is finished for one specification of the internal gear, the process is the same as that of the gear shaping mechanism in the prior art, and the details are not repeated; when the slotting cutter 2 needs to be replaced, the square shell 1 is firstly ejected and lifted by the second air cylinder 5, then the square shell is driven to rotate by the first air cylinder 4, when the proper slotting cutter 2 is in a working position, the first air cylinder 4 stops moving, the second air cylinder 5 drives the square shell 1 to descend, and the replaced slotting cutter 2 can perform slotting on the other specification of the internal teeth.

In a specific embodiment, the square housing 1 is provided with slotting tools 2 of different specifications at the same position on each side, and the rotation angle of the square housing 1 through the first cylinder 4 is 90 degrees each time. In this way, the main difference lies in that the same positions of four surfaces of the square shell 1 are all fixed with the slotting cutter 2 with different specifications, which can satisfy the internal teeth with four common specifications, and meanwhile, the rotating angle is 90 degrees when the slotting cutter 2 is replaced every time. The angle can be specifically limited by the sensor, and the replacement is convenient.
