Description

Technical Field

[0001] This utility model relates to the field of gear mechanism equipment technology, specifically to a gear hobbing device for machining track brake gears. Background Technology

[0002] In the field of rail transit equipment manufacturing, the gear hobbing devices currently widely used have significant technical bottlenecks in the design of the cutter replacement mechanism. Specifically, when traditional gear hobbing machines process different gear parts, changing the cutter requires the gradual disassembly of multiple fasteners, which is very time-consuming for each cutter change. This increases downtime and also reduces work efficiency. In order to solve the above problems, improve the production efficiency of gear hobbing, and achieve rapid replacement of the cutter, this utility model has emerged. Utility Model Content

[0003] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a gear hobbing device for machining track brake gears, comprising: a base, a motor fixedly connected to the bottom of the base, a connecting rod fixedly connected to the output end of the motor, a gear cutter disposed at the top of the connecting rod, a rotating device disposed outside the gear cutter, and a clamping device disposed inside the rotating device; the rotating device includes a threaded rod, a limit block fixedly connected to the outer wall of the threaded rod, a sleeve handle threadedly connected to the top of the threaded rod, a top plate rotatably connected to the bottom of the sleeve handle, a connecting column fixedly connected to the bottom of the top plate, a rotating disk fixedly connected to the bottom of the connecting column, a rotating block slidably connected to the bottom of the rotating disk, and a push spring fixedly connected to the bottom of the rotating block.

[0004] Preferably, the outer wall of the threaded rod is fixedly connected to the inner wall of the base, the bottom of the push spring is fixedly connected to the top of the base, the inner wall of the rotating block is slidably connected to the outer wall of the threaded rod, the inner wall of the rotating block is slidably connected to the outer wall of the limiting block, the inner wall of the connecting column is slidably connected to the outer wall of the threaded rod, and the inner wall of the top plate is slidably connected to the outer wall of the threaded rod. When the top sleeve handle is turned, the push spring at the bottom will push the rotating block upward without the force of the sleeve handle.

[0005] Preferably, the clamping device includes a threaded handle, a housing is threadedly connected to the outer wall of the threaded handle, a connecting bearing is slidably connected to the outer wall of the housing, a movable block is slidably connected to the outer wall of the threaded handle, a movable rod is slidably connected to the inner wall of the movable block, a rotating rod is rotatably connected to the inner wall of the movable rod, and a compression spring is fixedly connected to the bottom of the movable block. A limit rod is provided inside the movable block and is fixedly connected to the bottom housing, and the compression spring slides on the outer wall of the limit rod.

[0006] Preferably, the outer wall of the threaded handle is threadedly connected to the inner wall of the top plate, the outer wall of the outer shell is slidably connected to the inner wall of the toothed cutter, and the inner wall of the outer shell is rotatably connected to the outer wall of the rotating rod. By turning the threaded handle, the moving block at the bottom of the threaded handle moves upward under the rebound of the compression spring.

[0007] Preferably, the inner wall of the outer casing is fixedly connected to the bottom of the compression spring, and the inner wall of the outer casing is slidably connected to the outer wall of the movable rod. When the movable rods symmetrically arranged inside the outer casing move upward, the other end of the rotating rod will disengage from the inner wall of the connecting bearing, causing the movable rod to return to the outer casing.

[0008] Preferably, the outer wall of the movable rod is slidably connected to the inner wall of the connecting bearing, the outer wall of the connecting bearing is fixedly connected to the inner wall of the toothed cutter, and the inner wall of the toothed cutter is slidably connected to the outer wall of the connecting rod. By turning the sleeve handle at the top of the top plate, the bottom push spring pushes against the rotating plate, disengaging the toothed cutter from the bottom connecting rod, thereby achieving the effect of quick replacement.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model, by setting up a rotating device, allows the tooth cutter to be quickly replaced when different gears are being processed. This is achieved by using a threaded rod to allow the push spring and the rotating disk to work together, so that the tooth cutter can be disengaged from the connecting rod on the bottom motor output end. This effectively shortens the operation time and reduces equipment downtime.

[0011] 2. This utility model, by setting up a clamping device, allows the rotating device to be used in conjunction with the top sleeve handle to push out the rotating disk when the equipment's toothed cutter needs to be replaced or repaired. This pushes the toothed cutter inside the top disk away from the connecting rod at the bottom. Then, by rotating the threaded rod at the top, the compression spring at the bottom drives the internal movable rod to disengage from the inner wall of the connecting bearing, enabling the toothed cutter to be replaced quickly. This reduces equipment downtime and improves its working efficiency. Attached Figure Description

[0020] The outer wall of the threaded rod 11 is fixedly connected to the inner wall of the base 1, the bottom of the push spring 8 is fixedly connected to the top of the base 1, the inner wall of the rotating block 9 is slidably connected to the outer wall of the threaded rod 11, the inner wall of the rotating block 9 is slidably connected to the outer wall of the limiting block 10, the inner wall of the connecting column 12 is slidably connected to the outer wall of the threaded rod 11, and the inner wall of the top plate 13 is slidably connected to the outer wall of the threaded rod 11.

[0021] The clamping device 2 includes a threaded handle 21, a housing 22 is threadedly connected to the outer wall of the threaded handle 21, a connecting bearing 27 is slidably connected to the outer wall of the housing 22, a moving block 23 is slidably connected to the outer wall of the threaded handle 21, a movable rod 24 is slidably connected to the inner wall of the moving block 23, a rotating rod 25 is rotatably connected to the inner wall of the movable rod 24, and a compression spring 26 is fixedly connected to the bottom of the moving block 23.

[0022] The outer wall of the threaded handle 21 is threadedly connected to the inner wall of the top plate 13, the outer wall of the outer shell 22 is slidably connected to the inner wall of the toothed cutter 5, and the inner wall of the outer shell 22 is rotatably connected to the outer wall of the rotating rod 25.

[0023] The inner wall of the outer casing 22 is fixedly connected to the bottom of the compression spring 26, and the inner wall of the outer casing 22 is slidably connected to the outer wall of the movable rod 24.

[0024] The outer wall of the movable rod 24 is slidably connected to the inner wall of the connecting bearing 27, the outer wall of the connecting bearing 27 is fixedly connected to the inner wall of the toothed cutter 5, and the inner wall of the toothed cutter 5 is slidably connected to the outer wall of the connecting rod 28.

[0025] Working principle:

[0026] When in use, the base 1 is fixed to the ground as the base of the whole device. Then the motor 4 is started. The output end of the motor 4 drives the toothed cutter 5 in the rotating device 3 to rotate. The clamping device 2 at the top fixes the toothed cutter 5.

[0027] When different track brake gears need to be processed, by turning the sleeve handle 7 on the top of the rotating device 3, the push spring 8 at the bottom will push the rotating block 9 upward without the force of the sleeve handle 7. The rotating block 9 will drive the rotating disk 6, the rotating disk 6 will drive the connecting column 12, and the connecting column 12 will drive the top disk 13. The clamping device 2 inside the top disk 13 will take the bottom tooth cutter 5 away from the connecting rod 28 on the output end of the motor 4. Then, according to different track brake gears, the corresponding tooth cutter 5 on the top disk 13 can be rotated to achieve the effect of quickly replacing the tooth cutter 5. When it is necessary to fix the tooth cutter 5, the center point of the tooth cutter 5 can be rotated to the corresponding axial direction of the connecting rod 28 on the output end of the motor 4, and then the sleeve handle 7 is tightened to make the rotating disk 6 descend to the locking position. When the rotating disk 6 descends, the internal limiting hole will correspond to the limiting block 10 on the threaded rod 11 to play a limiting and fixing role to prevent displacement. The corresponding tooth cutter 5 will also descend to the connecting rod 28 on the output end of the motor 4 to achieve the fixing effect.

[0028] When the toothed cutter 5 needs to be replaced or repaired, the clamping device 2 can work in conjunction with the rotating device 3. By turning the sleeve handle 7 on the top of the top plate 13, the bottom push spring 8 pushes against the rotating plate 6, disengaging the toothed cutter 5 from the connecting rod 28 on the output end of the motor 4. Then, by turning the threaded handle 21 on the top plate 13, the moving block 23 at the bottom of the threaded handle 21 will move upward under the rebound of the compression spring 26. When the moving block 23 moves, it will drive the movable rod 24 on the inner wall to move upward. When the movable rod 24 moves upward, the other end of the rotating rod 25 will disengage from the inner wall of the connecting bearing 27, allowing the movable rod 24 to return to the outer shell 22, thus releasing the clamp. At this point, the toothed cutter 5 can be removed for replacement and repair.
