Description

Technical Field

[0001] The present invention belongs to the technical field of end tooth machining, and particularly relates to an end tooth end face polishing device. Background Art

[0002] An end tooth is a type of gear that mates with a spur gear or a helical gear at a 90-degree shaft intersection angle. The central axes of the pinion and the face gear of this type of gear are perpendicular. The two perpendicular central axes can intersect or have an offset distance. The face gear is mainly applied to industries such as helicopters, fishing reels, watches, and bicycles. Its heavy-duty and stable transmission characteristics have a relatively wide application space.

[0003] During the production process of end teeth, the end teeth need to be polished. One end face of the two end faces of the end tooth is the gear end face, and the other end face is a smooth end face. During the polishing process of the end tooth by a conventional polishing device, after one end face of the end tooth is processed, it is necessary to first disassemble the polishing disc, and then replace different polishing discs to process the other end face of the end tooth. The installation and disassembly steps are cumbersome, and after replacing the polishing disc, it is necessary to position and process the end tooth, which is relatively cumbersome. On this basis, the applicant of the present invention has proposed a new type of polishing device. Summary of the Invention

Embodiment

[0026] Refer to Figures 1-4, this embodiment provides a device for polishing the end face of end teeth, including a workbench 2. There is a placement groove 21 for placing end teeth on the workbench 2. A crossbeam is provided on the top of the workbench 2. A rotating motor 5 is provided at the bottom of the crossbeam. The output end of the rotating motor 5 is provided with a turntable 1. Four annularly distributed support rods 3 are fixedly provided at the outer edge of the bottom of the turntable 1. Installation holes are opened on one side of the lower ends of the four support rods 3, and a first insertion rod 32 and a second insertion rod 431 are movably inserted into the installation holes. Two groups of support rods 3 arranged diagonally are respectively supported and connected by the first insertion rod 32 and the second insertion rod 431 to form a polishing disc 4. A first polishing disc 41 for polishing the end face of the gear is provided on the top surface of the polishing disc 4, and a second polishing disc 42 for polishing the smooth end face is provided on the bottom surface of the polishing disc 4. By inserting and removing the second insertion rod 431, the replacement of the first polishing disc 41 and the second polishing disc 42 is realized. During the rotation of the rotating motor 5, the polishing disc 4 is driven to rotate accordingly, thereby polishing the surface of the end teeth.

[0027] In this embodiment, slots 31 and a first clamping groove 43 adapted to the first insertion rod 32 and the second insertion rod 431 are opened inside the polishing disc 4. A first spring 432 is provided inside the first clamping groove 43. The bottom end of the first spring 432 is fixedly connected to the bottom of the first clamping groove 43, and the top end of the first spring 432 is fixedly connected to a pressing block 433. A traction groove 44 communicating with it is opened at the bottom of the first clamping groove 43. The bottom end of the second insertion rod 431 is successively provided with the pressing block 433 and the first spring 432 inserted into the traction groove 44. A traction rope 434 is fixedly connected to the middle of the bottom end of the second insertion rod 431. A pressing groove 45 is opened in the middle of the polishing disc 4. A pressing column 451 is provided inside the pressing groove 45. The traction rope 434 passes through the bottom of the traction groove 44 and is fixedly connected to the outer side of the upper end of the pressing column 451. When the pressing block 452 presses the pressing column 451 to move towards the bottom of the second clamping groove 46, one end of the traction rope 434 is driven to move towards the bottom of the groove, so that the second insertion rod 431 shrinks inside the first clamping groove 43, enabling the polishing disc 4 to flip according to the first insertion rod 32, so that both ends of the polishing disc 4 can be conveniently switched to process different surfaces of the end teeth, improving work efficiency;

[0028] Among them, a second clamping groove 46 communicating with it is opened at the bottom of the pressing groove 45. A second spring 453 is provided inside the second clamping groove 46. The top end and the bottom end of the second spring 453 are respectively fixedly connected to the bottom of the second clamping groove 46 and the top end of the pressing column 451. The bottom end of the pressing column 451 is fixedly attached to a pressing block 452. A through groove 47 communicating with it is opened at the notch of the pressing groove 45. A limiting block 471 adapted to it is provided inside the through groove 47. The pressing column 451 can automatically reset, so that the second insertion rod 431 is inserted into the corresponding jack.

[0029] Among them, the first insertion rod 32 and the second insertion rod 431 are alternately inserted into the jacks at the bottom ends of the four support rods 3. One end of the first insertion rod 32 away from the jack is fixedly inserted into the inside of the slot 31. Specifically, the two first insertion rods 32 are symmetric with each other, and the two second insertion rods 431 are symmetric with each other.

[0030] Among them, the straight-line distance from the bottom end of the second insertion rod 431 to the bottom of the traction groove 44 is equal to the straight-line distance from the top end of the second insertion rod 431 to the notch of the first card slot 43. The traction rope 434 has no extensibility. The traction rope 434 is in a straightened state between the second insertion rod 431 and the pressing column 451. When the traction rope 434 drives the bottom end of the second insertion rod 431 to displace to the bottom position of the first card slot 43, the top end of the second insertion rod 431 is exactly on the same horizontal plane as the notch of the first card slot 43, without affecting the flipping operation of the polishing disc 4 with respect to the first insertion rod 32.

[0031] Among them, pins are provided on both sides of the outer circle of the notch of the second card slot 46, and the bottom ends of the pins are on the same horizontal plane as the top ends of the through holes formed by the traction rope 434 passing through the bottom of the traction groove 44, avoiding the traction rope 434 from contacting the sharp notch, so that the traction rope 434 is not easily worn.

[0032] Among them, the limiting block 471 is inserted into the through groove 47, and there is a damping effect between the limiting block 471 and the through groove 47. A damper or frictional connection is provided between them. The second polishing disc 42 is provided at the bottom end of the limiting block 471, so that the limiting block 471 is not easily slipped out of the inside of the through groove 47 during the polishing process.

[0033] In the present invention, pins are provided on both sides of the outer circle of the notch of the second card slot 46, and the bottom ends of the pins are on the same horizontal plane as the top ends of the through holes formed by the traction rope 434 passing through the bottom of the traction groove 44, avoiding the traction rope 434 from contacting the sharp notch, so that the traction rope 434 is not easily worn.

[0034] Working principle: Place the end teeth into the placement groove 21 for fixation, and turn on the rotation motor 5 to process one end face. When it is necessary to polish the other end face of the end teeth, remove the limit block 471, press the pressing block 452, so that the pressing column 451 moves towards the bottom of the second card slot 46, thereby making one end of the traction rope 434 fixedly connected to the outer side of the upper end of the pressing column 451 move towards the bottom of the second card slot 46. The traction rope 434 moves the second plug rod 431 towards the bottom of the traction groove 44. When the bottom end of the second plug rod 431 moves to the bottom position of the traction groove 44, the top end of the second plug rod 431 and the notch of the first card slot 43 are on the same horizontal plane. Pull out the second plug rod, that is, release the limit locking of the second plug rod 431 by the jack at the lower end of the support rod 3, so that the polishing disc 4 can be flipped about the first plug rod 32. After the polishing disc 4 is flipped 180 degrees, release the pressing block 452. The first spring 432 and the second spring 453 cooperate to reset the pressing column 451 and the second plug rod 431. The jack at the lower end of the support rod 3 is inserted into the second plug rod 431 again for limit locking. At this time, turn on the rotation motor 5 to process the other end face of the end teeth.

[0035] The above embodiments only represent a certain implementation mode of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention; therefore, the protection scope of the invention patent should be subject to the appended claims.
