Description

Technical Field

[0001] This invention belongs to the field of gear processing technology, and in particular relates to a gear grinding equipment for the production of tricycle parts. Background Technology

[0002] Gears are mechanical components with teeth on their rims that continuously mesh to transmit motion and power. They appeared very early in the application of transmission and are widely used in various fields of machinery due to their smooth and continuous transmission. Gears are an indispensable component in gearboxes; their quality determines the stability of the transmission, the accuracy of the reduction ratio, and the level of vibration and noise. In cycloidal pinwheel reducers, high requirements are placed on the tooth profile accuracy and flatness of the gears. After gears are machined by gear processing machines, some burrs inevitably remain on their outer circumference, making their surface uneven. These freshly machined gears are generally not sold directly; they need to be ground and deburred first. Existing gear grinding operations typically involve manual grinding, although mechanical grinding is also used. However, this requires constant adjustment of the grinding head position, making the operation cumbersome and prone to collisions between the grinding head and the gear, resulting in poor grinding quality. To avoid these issues, a gear grinding device for tricycle parts production is provided. Summary of the Invention

[0011] Preferably, the fixing mechanism includes a steering motor fixedly connected to the outer wall of the upper support frame and a first rotating rod rotatably connected to the inner wall of the upper support frame. The output shaft of the steering motor is fixedly connected to one end of the first rotating rod via a coupling. A connecting seat is fixedly connected to the outer wall of the first rotating rod.

[0013] Compared with the prior art, the embodiments of this application have the following main advantages: By setting up and coordinating the lower support assembly, upper support frame, end face grinding mechanism, tooth groove grinding mechanism, and polishing assembly, an automated and precise gear grinding system is constructed. This combination of mechanisms seamlessly connects the rough grinding, fine grinding, and cleaning processes, which not only significantly reduces manual intervention and improves the convenience and safety of operation, but also fundamentally solves the problems of difficult grinding precision control and low efficiency in traditional methods, and significantly improves the tooth profile accuracy and flatness of gears. The fixing mechanism employs a unique design: the clamping components move via opposing internal electric telescopic rods and are securely radially clamped from the inner wall of the gear by an internal support block. This internal clamping method not only ensures the gear's stability during high-speed grinding but also avoids interference with the external tooth surface. Furthermore, the fixing mechanism integrates dual-axis drive control: the tooth groove adjustment motor drives the fixed inner frame to rotate via a second rotating rod, allowing the gear to rotate in sequence with the tooth groove grinding mechanism, achieving sequential and precise grinding of each tooth groove; while the steering motor drives the entire fixing mechanism and gear to rotate via a first rotating rod, ensuring that both the upper and lower end faces of the gear face the end face grinding mechanism, completing automatic grinding of both end faces. This design, combining "stable clamping" and "flexible steering," allows the gear to complete multi-angle, all-around grinding operations without re-clamping, greatly simplifying the operation process, improving processing efficiency, and ensuring the accuracy of the relative position between the grinding head and the gear. This effectively avoids the risk of collision due to gear position changes, significantly improving the overall grinding quality. Attached Figure Description

Among them, the tooth groove grinding mechanism 3 includes a side support slide 301 fixedly connected to the outer wall of the upper support frame 6, and an adjustment component 302 is provided on the inner wall of the side support slide 301. The output end of the adjustment component 302 is fixedly connected to the tooth groove grinding stone 303. The shape and size of the tooth grinding stone 303 need to be selected according to the formation and size of the tooth groove of the gear to be ground; In use, the telescopic hydraulic cylinder 3021 is activated and controlled according to the diameter of the gear to be ground and the position of the tooth groove to move and adjust the position of the tooth groove grinding stone 303. The position of the tooth groove grinding stone 303 is raised and lowered to achieve grinding of the inner wall of the tooth groove of the gear to be ground by the tooth groove grinding stone 303.

[0019] The control component 302 includes a telescopic hydraulic cylinder 3021 fixedly connected to the outer wall of the upper support frame 6 and an inner slider 3022 slidably connected to the inner wall of the side support slide groove 301. The telescopic end of the telescopic hydraulic cylinder 3021 is fixedly connected to the outer wall of the inner slider 3022. A lifting hydraulic cylinder 3023 is fixedly connected to the upper outer wall of the inner slider 3022. A first mounting base 3024 is fixedly connected to the telescopic end of the lifting hydraulic cylinder 3023. The toothed grinding stone block 303 and the first mounting base 3024 are fitted together and inserted into each other, and the toothed grinding stone block 303 and the first mounting base 3024 are fixedly connected by bolts.

[0020] The end face grinding mechanism 5 includes a slide cylinder assembly 501. A support crank 502 is fixedly connected to the outer wall of the slide cylinder assembly 501. A second mounting base 504 is fixedly connected to the upper end of the support crank 502. An end face grinding stone 503 is fitted and inserted into the inner wall of the second mounting base 504.

[0021] The end face polishing stone 503 is equipped with upper and lower double-sided polishing areas.

[0022] The slide assembly 501 includes a slide 5011, and the inner wall of the slide 5011 has a plurality of annular toothed grooves 5012, which are equidistantly arranged.

[0023] The lower support assembly 1 includes a base 101, a lower support 102 is fixedly connected to the upper end of the base 101, the bottom of the upper support frame 6 is fixedly connected to the top of the lower support 102, the inner wall of the slide cylinder 5011 is slidably connected to the outer wall of the lower support 102, a lifting motor 103 is fixedly connected to the outer wall of the lower support 102, the output shaft of the lifting motor 103 is fixedly connected to a linkage short shaft through a coupling, a lifting gear 104 is fixedly connected to one end of the linkage short shaft, and the lifting gear 104 is meshed with multiple annular toothed grooves 5012. In use, the lifting motor 103 is started and controlled. Because the lifting gear 104 is meshed with multiple annular toothed grooves 5012, it can drive the slide cylinder 5011 to move up and down along the outer wall of the lower support 102 to move the position of the end face grinding stone 503, thereby realizing the cooperation between the end face grinding stone 503 and the outer wall of the end face of the gear to be ground; at the same time, because the lifting gear 104 is meshed with multiple annular toothed grooves 5012, and the slide cylinder 5011 and the outer wall of the lower support 102 are in close contact and rotating connection. Rotating the slide cylinder 5011 adjusts the position of the support crank 502 and the end face grinding stone 503. When the support crank 502 and the end face grinding stone 503 are tilted to the front side (i.e., the flat side) of the upper support frame 6 at approximately 30 to 60 degrees, continue to start and control the lifting motor 103 to move the end face grinding stone 503 upward. The end face grinding stone 503 can smoothly pass through the upper support frame 6 until it is above the gear to be ground. Rotate the end face grinding stone 503 to position it... At the diameter of the end face of the gear to be ground, the end face grinding stone 503 achieves maximum utilization. The lifting motor 103 then finely adjusts the end face grinding stone 503 to ensure close contact with the gear, achieving a better grinding effect on the upper end face of the gear. When grinding the lower end face of the gear: if the gear thickness is small, the end face grinding stone 503 can be rotated and its height adjusted using the lifting motor 103, allowing the upper end face of the end face grinding stone 503 to directly grind the gear. The lower end face is polished. If the gear is thick, the end face polishing stone 503 is rotated and the height is adjusted to the lowest position in conjunction with the lifting motor 103. The steering motor 201 is started and controlled to drive the first rotating rod 203 to rotate. The gear to be polished is rotated 180 degrees downward and kept in an upright and drooping state. The height is adjusted by rotating the end face polishing stone 503 and in conjunction with the lifting motor 103. The lower end face of the end face polishing stone 503 is used to polish the upper end face of the gear at this time (i.e. the original lower end face).

[0024] The polishing assembly 4 includes a polishing and cleaning box 401 fixedly connected to the outer wall of the upper support frame 6. A cover plate 402 is hinged to the upper part of the polishing and cleaning box 401. A fixed side block 404 is fixedly connected to the outer wall of the polishing and cleaning box 401. A retractable hydraulic cylinder 403 is hinged to the upper side of the fixed side block 404. A connecting ball is fixedly connected to the telescopic end of the retractable hydraulic cylinder 403. A ball cover is movably connected to the outer wall of the connecting ball. The top of the ball cover is fixedly connected to the outer wall of the cover plate 402. The inner wall of the polishing and cleaning box 401 contains fine abrasive stones. During use, after the end face and tooth groove of the gear to be ground are ground, the hydraulic cylinder 403 is started and controlled to pull open the cover plate 402, the steering motor 201 is started and controlled to drive the first rotating rod 203 to rotate, and the gear to be ground is placed into the box. The cover plate 402 is closed, the tooth groove adjustment motor 204 is started and controlled to drive the gear to be ground to rotate in the polishing and cleaning box 401 through the second rotating rod 205 for fine grinding and to clean the powder off the gear to be ground.

[0025] It should be noted that in existing gear grinding operations, manual grinding is usually used, although mechanical grinding is also used. However, the position of the grinding head needs to be constantly adjusted, which is cumbersome and prone to collision between the grinding head and the gear, resulting in poor grinding effect.

[0026] Specifically, in this embodiment, the solution mainly uses the lower support base assembly 1, upper support frame 6, end face grinding mechanism 5, tooth groove grinding mechanism 3, fixing mechanism 2 and polishing assembly 4 for setup and cooperation. In use, firstly, the internal electric telescopic rod 2071 is activated and controlled to extend and retract the support rod 2072, so that the support rod 2072 moves stably outward or retracts inward along the inner wall of the fixed inner frame 206, thereby adjusting the position of the inner support block 2073 on the support rod 2072. The inner support block 2073 is in close contact with the inner wall of the gear to be ground, so as to achieve the fixed clamping of the position of the gear to be ground. Then, based on the diameter of the gear to be ground and the position of the tooth groove, the telescopic hydraulic cylinder 3021 is started and controlled to move and adjust the position of the tooth groove grinding stone 303, and is started and controlled to raise and lower the position of the tooth groove grinding stone 303, thereby achieving the grinding of the inner wall of the tooth groove of the gear to be ground by the tooth groove grinding stone 303. At the same time, the lifting motor 103 is started and controlled. Because the lifting gear 104 is meshed with multiple annular toothed grooves 5012, it can drive the slide cylinder 5011 to move up and down along the outer wall of the lower support 102 to move the position of the end face grinding stone 503. This allows the end face grinding stone 503 to cooperate with the end face outer wall of the gear to be ground. When the gear to be ground rotates, the end face grinding stone 503 contacts the end face of the gear to be ground, which is the end face grinding. At the same time, because the lifting gear 104 is meshed with multiple annular toothed grooves 5012, the lifting motor 104 is used to move the position of the end face grinding stone 503 along the outer wall of the lower support 102. The slide cylinder 5011 and the lower support 102 are meshed and connected, and the outer walls of the slide cylinder 5011 and the lower support 102 are rotatably connected. Rotating the slide cylinder 5011 can adjust the position of the support crank 502 and the end face grinding stone 503. When the support crank 502 and the end face grinding stone 503 are tilted to the front side (i.e., the plane side) of the upper support frame 6 at approximately 30 to 60 degrees, the lifting motor 103 is started and controlled to move the end face grinding stone 503 upward. The end face grinding stone 503 can smoothly pass through the upper support frame 6 until the end face grinding stone 503 is in the waiting position. Above the gear being ground, the end-face grinding stone 503 is rotated to position itself on the diameter of the end face of the gear to be ground. At this point, the end-face grinding stone 503 reaches its maximum utilization rate. Then, the lifting motor 103 is used for fine-tuning to ensure close contact between the end-face grinding stone 503 and the gear, achieving a better grinding effect on the upper end face of the gear. When grinding the lower end face of the gear: if the gear thickness is small, the height can be adjusted directly by rotating the end-face grinding stone 503 and using the lifting motor 103. The end face is directly polished on the lower end face of the gear to be ground. If the gear is thick, the end face polishing stone 503 is rotated and the height is adjusted to the lowest position in conjunction with the lifting motor 103. The steering motor 201 is started and controlled to drive the first rotating rod 203 to rotate, so that the gear to be ground is rotated 180 degrees downward and kept in an upright and hanging state. The height is adjusted by rotating the end face polishing stone 503 and in conjunction with the lifting motor 103. The lower end face of the end face polishing stone 503 is used to polish the upper end face (i.e. the original lower end face) of the gear at this time. After the end face and tooth groove of the gear to be ground are ground, the hydraulic cylinder 403 is started and controlled to pull open the cover plate 402, the steering motor 201 is started and controlled to drive the first rotating rod 203 to rotate, and the gear to be ground is placed into the box. The cover plate 402 is closed, the tooth groove adjustment motor 204 is started and controlled to drive the gear to be ground to rotate in the polishing and cleaning box 401 through the second rotating rod 205 for fine grinding and to clean the powder off the gear to be ground.

[0027] In this embodiment, the tooth grinding mechanism 3 achieves independent and precise driving of the tooth grinding stone 303 in the horizontal and vertical directions through the control component 302. It can adaptively position itself according to the diameter of the gear to be ground and the tooth groove position, avoiding hard collision between the grinding head and the gear, and ensuring stable and efficient grinding of the inner wall of the tooth groove. In this embodiment, the end face grinding mechanism 5 utilizes the cooperation between the slide cylinder assembly 501 and the lower support base assembly 1, and drives the slide cylinder 5011 to move up and down along the lower support base 102 through the lifting motor 103, thereby precisely adjusting the position of the end face grinding stone 503 so that it can stably contact the gear end face, and realize synchronous grinding of the gear end face. In this embodiment, the polishing component 4 serves as a finishing process. By placing the gear that has undergone preliminary polishing into a polishing and cleaning box 401 containing fine abrasive, the rotational motion of the gear is used to achieve fine polishing and dust removal of the gear surface and tooth grooves.

[0028] In a further preferred embodiment of the present invention, the fixing mechanism 2 includes a steering motor 201 fixedly connected to the outer wall of the upper support frame 6 and a first rotating rod 203 rotatably connected to the inner wall of the upper support frame 6. The output shaft of the steering motor 201 is fixedly connected to one end of the first rotating rod 203 through a coupling. A connecting seat 202 is fixedly connected to the outer wall of the first rotating rod 203. A toothed adjustment motor 204 is fixedly connected to the outer wall of the connecting seat 202. The output shaft of the toothed adjustment motor 204 is fixedly connected to a second rotating rod 205 through a coupling. One end of the second rotating rod 205 is fixedly connected to a fixed inner frame 206. A clamping assembly 207 is provided on the top inner wall of the fixed inner frame 206. In use, the steering motor 201 is started and controlled to drive the first rotating rod 203 to rotate, which can realize the position adjustment of other structures on the first rotating rod 203 and the gear to be ground as a whole, so as to adjust the position of the upper and lower end faces of the gear to be ground, and then cooperate with the end face grinding mechanism 5 to perform end face grinding. After the clamping assembly 207 clamps and fixes the gear to be ground, the tooth groove adjustment motor 204 is started and controlled. The tooth groove adjustment motor 204 drives the second rotating rod 205 to rotate, which in turn drives the fixed inner frame 206 to rotate, thereby rotating and adjusting the position of the gear to be ground so as to cooperate with the tooth groove grinding mechanism 3 to perform internal tooth groove grinding. The clamping assembly 207 includes an inner electric telescopic rod 2071 fixedly connected to the inner wall of the fixed inner frame 206. The telescopic end of the inner electric telescopic rod 2071 is fixedly connected to a support rod 2072. One end of the support rod 2072 is fixedly connected to an inner support block 2073. The outer wall of the inner support block 2076 is provided with an anti-slip groove. The number of clamping components 207 is two, and the two clamping components 207 are arranged facing each other; In use, the internal electric telescopic rod 2071 is activated and controlled to extend and retract the support rod 2072, so that the support rod 2072 moves stably outward or retracts inward along the inner wall of the fixed inner frame 206, thereby adjusting the position of the inner support block 2073 on the support rod 2072. The inner support block 2073 is in close contact with the inner wall of the gear to be ground, so as to achieve the fixed clamping of the gear to be ground.

[0029] In this embodiment, the clamping component 207 in the fixing mechanism 2 moves via the opposing inner electric telescopic rod 2071 and is securely radially clamped from the inner wall of the gear by the inner support block 2073. In this embodiment, the tooth groove adjustment motor 204 drives the fixed inner frame 206 to rotate through the second rotating rod 205, so that the gear can cooperate with the tooth groove grinding mechanism 3 to perform indexing rotation, thereby achieving sequential and precise grinding of each tooth groove; while the steering motor 201 drives the entire fixed mechanism 2 and the gear to rotate through the first rotating rod 203, so that the upper and lower end faces of the gear can face the end face grinding mechanism 5, thereby completing the automatic grinding of the double end faces.
