Description

Technical Field

[0001] This utility model relates to the field of positioning fixtures, and in particular to a positioning fixture for gear processing. Background Technology

[0002] Gear machining is the process of machining a gear blank into a gear with a specific tooth profile and dimensional accuracy. It encompasses various processes such as turning, milling, hobbing, and gear shaping. The goal is to make the gear meet different mechanical transmission requirements. Precise positioning is crucial in gear machining. Positioning fixtures can ensure that the gear blank is fixed and accurate in position during the machining process, thereby ensuring that the machined gear meets high precision standards and improving machining quality and efficiency.

[0003] Most existing positioning fixtures are fixed structures with poor flexibility. When faced with diverse gear processing requirements, they cannot quickly and accurately adjust the clamping position and angle, resulting in low processing efficiency and easy positioning deviations, which affect the processing accuracy and quality of gears. Therefore, those skilled in the art provide a positioning fixture for gear processing to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a positioning fixture for gear processing. The fixture has high overall flexibility and is relatively simple to operate.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A positioning fixture for gear processing includes a fixture body and a gear body. A rotating mechanism is provided on one side of the fixture body, a clamping mechanism is provided on one side of the rotating mechanism, and a limit mechanism is provided on one side of the clamping mechanism.

[0007] The clamp body includes a fixed base and a movable plate. A slide rail is fixedly installed on one side of the fixed base. The rotating mechanism includes a fixed column and a rotating base. A servo motor is fixedly installed inside the fixed column. The clamping mechanism includes a fixed frame, a fixed block, and two movable support blocks. A bidirectional screw is rotatably installed inside the fixed frame. An adjusting rod is fixedly installed at the upper end of the bidirectional screw. A locking rod is installed on one side of the adjusting rod. Protective pads are fixedly installed on the outer surfaces of the two movable support blocks. The limiting mechanism includes a threaded rod and a limiting plate. A limiting block is threadedly sleeved on the outer surface of the threaded rod.

[0008] Furthermore, the bottom of the fixed base is provided with multiple fixing holes, and one side of the movable plate is threaded with multiple fixing bolts.

[0009] Furthermore, one side of the movable plate is slidably disposed on the outer surface of the slide rail, and the other side of the movable plate is fixedly connected to the fixed column.

[0010] Furthermore, one side of the rotating base is rotatably connected to the fixed column, and the servo motor output end is fixedly connected to the rotating base.

[0011] Furthermore, the fixing block is fixedly sleeved on the outer surface of the middle part of the bidirectional screw, and the two movable support blocks are respectively threaded onto the outer surfaces of both sides of the bidirectional screw.

[0012] Furthermore, one side of the threaded rod is fixedly connected to the fixing block.

[0013] Furthermore, the limiting disc is slidably sleeved on the outer surface of the threaded rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a positioning fixture for gear processing. In the fixture body, through the design of slide rails and moving plates, the position of the rotating mechanism can be conveniently adjusted according to the actual processing needs. In the rotating mechanism, the servo motor can drive the rotating seat to realize multi-angle rotation of the clamping mechanism and the limiting mechanism, easily meeting the requirements of different gear processing angles. In the clamping mechanism, the bidirectional screw and the adjusting rod can accurately control the position of the moving support block to stably clamp the inner wall of the gear. The threaded rod of the limiting mechanism, together with the limiting block and the limiting plate, can accurately limit the axial position of the gear, ensuring accurate gear positioning throughout the entire processing process, greatly improving the accuracy and quality of gear processing.

[0016] 2. The positioning fixture for gear processing proposed in this utility model has a protective pad on the outer surface of the moving support block of the clamping mechanism. When clamping the inner wall of the gear, it effectively avoids scratching or damaging the gear, extends the service life of the gear, and ensures product quality. When adjusting the position of the fixture, it is only necessary to loosen or tighten the fixing bolt. The operation of clamping and releasing the gear can be easily achieved by rotating the adjusting rod. The locking rod can ensure the stability of the adjusted position. The whole operation process is simple and efficient, reducing the difficulty of the operator's work and improving work efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-4 One embodiment of this utility model is a positioning fixture for gear processing, which includes a fixture body 1 and a gear body 2. A rotating mechanism 3 is provided on one side of the fixture body 1, a clamping mechanism 4 is provided on one side of the rotating mechanism 3, and a limit mechanism 5 is provided on one side of the clamping mechanism 4.

[0025] Specifically, the fixture body 1 is the basic support part of the entire positioning fixture, providing a stable platform for the installation and operation of other mechanisms. The rotating mechanism 3 can drive the clamping mechanism 4 and the limiting mechanism 5 to rotate, which facilitates the adjustment of the processing angle of the gear body 2. The clamping mechanism 4 is used to clamp and fix the gear body 2 to ensure that the gear body 2 will not be displaced during the processing. The limiting mechanism 5 further limits the position of the gear body 2 to improve the positioning accuracy.

[0026] Reference Figure 1-3 The fixture body 1 includes a fixed base 102 and a movable plate 105. A slide rail 103 is fixedly installed on one side of the fixed base 102. Multiple fixing holes 101 are opened at the bottom of the fixed base 102. Multiple fixing bolts 104 are threadedly connected to one side of the movable plate 105. One side of the movable plate 105 is slidably installed on the outer surface of the slide rail 103. The other side of the movable plate 105 is fixedly connected to the fixed column 301. The rotating mechanism 3 includes a fixed column 301 and a rotating seat 303. A servo motor 302 is fixedly installed inside the fixed column 301. One side of the rotating seat 303 is rotatably connected to the fixed column 301. The output end of the servo motor 302 is fixedly connected to the rotating seat 303.

[0027] Specifically, in the fixture body 1, the fixed seat 102 can be fixed to the processing equipment by bolts or other connecting parts through the fixed hole 101 at the bottom. The slide rail 103 provides a guiding function for the sliding of the moving plate 105. The moving plate 105 can be fixed in position on the slide rail 103 by the fixing bolt 104, thereby adjusting the position of the rotating mechanism 3. In the rotating mechanism 3, when the servo motor 302 is working, its output end drives the rotating seat 303 to rotate, thereby realizing the angle adjustment of the clamping mechanism 4 and the limiting mechanism 5.

[0028] Reference Figure 1 , Figure 4 The clamping mechanism 4 includes a fixed frame 403, a fixed block 404, and two movable support blocks 406. A bidirectional screw 405 is rotatably installed inside the fixed frame 403. An adjusting rod 401 is fixedly installed at the upper end of the bidirectional screw 405. A locking rod 402 is installed on one side of the adjusting rod 401. Protective pads 407 are fixedly installed on the outer surfaces of the two movable support blocks 406. The fixed block 404 is fixedly sleeved on the outer surface of the middle part of the bidirectional screw 405. The two movable support blocks 406 are respectively threaded on the outer surfaces of the two sides of the bidirectional screw 405. One side of the threaded rod 501 is fixedly connected to the fixed block 404. The limiting mechanism 5 includes a threaded rod 501 and a limiting plate 503. The limiting block 502 is threadedly sleeved on the outer surface of the threaded rod 501. The limiting plate 503 is slidably sleeved on the outer surface of the threaded rod 501.

[0029] Specifically, in the clamping mechanism 4, rotating the adjusting rod 401 can drive the bidirectional screw 405 to rotate. Since the threads on both sides of the bidirectional screw 405 are opposite, the two movable support blocks 406 will move towards or away from each other under the drive of the bidirectional screw 405. When moving away from each other, the movable support blocks 406 are in close contact with the inner wall of the gear body 2 and gradually apply pressure to clamp the gear body 2. When moving towards each other, the clamping of the gear body 2 is released. The locking rod 402 can lock the adjusting rod 401 after the position of the movable support block 406 is adjusted to prevent it from rotating accidentally. The protective pad 407 can prevent the movable support block 406 from scratching or damaging the inner wall of the gear body 2 during the clamping process. In the limiting mechanism 5, the position of the limiting block 502 on the threaded rod 501 can be adjusted by rotating the limiting block 502. The limiting disk 503 can slide on the threaded rod 501. The two work together to limit the axial position of the gear body 2.

[0030] Working principle: When using this fixture, firstly, according to the processing requirements, adjust the position of the moving plate 105 on the slide rail 103 using the fixing bolts 104 to fix the fixture body 1 in a suitable location. Next, place the gear body 2 around the two moving support blocks 406, rotate the adjusting rod 401 to cause the bidirectional screw 405 to drive the two moving support blocks 406 to move in opposite directions until the moving support blocks 406 are in close contact with the inner wall of the gear body 2 and clamp them. Then, use the locking rod 402 to lock the adjusting rod 401. Afterwards, according to the axial dimension of the gear body 2, rotate the limiting block 502 to adjust... Adjust its position on the threaded rod 501, slide the limiting plate 503 to make it contact the gear body 2, and limit the axial position of the gear body 2. If it is necessary to adjust the machining angle of the gear body 2, start the servo motor 302. The servo motor 302 drives the rotating seat 303 to rotate, so that the clamping mechanism 4, the limiting mechanism 5 and the clamped gear body 2 rotate together to a suitable angle. After the gear machining is completed, release the locking rod 402, rotate the adjusting rod 401 in the opposite direction, so that the two moving support blocks 406 move towards each other, release the clamping on the inner wall of the gear body 2, and the machined gear can be taken out.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
