[0001] This utility model belongs to the technical field of automated equipment, and in particular relates to a deburring machine for wheel-shaped processed parts. Background Technology

[0002] During machining processes such as turning, milling, gear hobbing, or stamping, wheel-shaped parts (such as flexible wheels and steel wheels) often develop burrs, flash, or microscopic unevenness on their edges. These burrs not only affect the assembly accuracy and service life of the parts but may also cause the following problems:

[0003] Assembly interference: Burrs may prevent wheel-shaped parts from being assembled correctly; Increased wear: Unremoved burrs may fall off during operation, causing abnormal wear of the friction pair and shortening the service life of the equipment; Safety hazards: Metal burrs are sharp and can easily cut operators, and may fly off at high speeds, posing a safety risk.

[0004] Currently, most companies use manual methods such as filing or sandpaper to polish burrs. However, the quality and precision of deburring cannot be guaranteed, and manual deburring also poses certain safety hazards.

[0005] Therefore, there is a need to provide a deburring machine for wheel-shaped workpieces. Utility Model Content

[0031] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0032] like Figures 1 to 7 As shown, the deburring machine for wheel-shaped workpieces includes an operating table 1. The operating table 1 is equipped with a grinding disc feeding mechanism 4, a grinding disc adsorption and flipping mechanism 2, and a wheel-shaped workpiece positioning and rotating mechanism 3. Wheel-shaped workpieces, such as flexible wheels or steel wheels, are placed on the wheel-shaped workpiece positioning and rotating mechanism 3. The grinding disc adsorption and flipping mechanism 2 and the wheel-shaped workpiece positioning and rotating mechanism 3 are positioned opposite each other on the operating table 1. Therefore, in actual operation, the grinding disc 6 needs to be flipped at an angle so that it can grind and deburr the wheel-shaped workpieces on the wheel-shaped workpiece positioning and rotating mechanism 3. Thus, the grinding disc adsorption and flipping mechanism 2 is provided to adsorb the grinding disc 6 from the grinding disc feeding mechanism 4 and flip it to grind and deburr the wheel-shaped workpieces on the wheel-shaped workpiece positioning and rotating mechanism 3.

[0033] Specifically, such as Figure 2 As shown, the grinding disc adsorption and flipping mechanism 2 includes a support column 200, a rotary cylinder 201, a connecting plate 202, an electric push rod 203, and an adsorption plate 204. The support column 200 is vertically fixed on the operating table 1, the rotary cylinder 201 is fixedly installed on the support column 200, the electric push rod 203 is connected to the rotary cylinder 201 through the connecting plate 202, and the adsorption plate 204 is fixedly installed at the bottom of the electric push rod 203. The adsorption plate 204 is used to adsorb the grinding discs 6 on the grinding disc feeding mechanism 4. The adsorption plate 204 uses the vacuum adsorption principle to adsorb the grinding discs 6, and the grinding discs 6 can be sandpaper that causes the least wear to wheel-shaped workpieces.

[0034] In actual operation, before the rotary cylinder 201 is started, the adsorption plate 204 at the bottom of the electric push rod 203 faces the grinding disc 6 on the grinding disc feeding mechanism 4. After the electric push rod 203 is started, the adsorption plate 204 uses its adsorption properties to adsorb the grinding disc 6 on the grinding disc feeding mechanism 4. After the rotary cylinder 201 is started, the electric push rod 203 rotates with the rotary cylinder 201 at an angle, so that the adsorption plate 204 also rotates at an angle, so that the grinding disc 6 adsorbed by the adsorption plate 204 contacts the wheel-shaped workpiece on the wheel-shaped workpiece positioning and rotating mechanism 3 and grinds and deburrs the edge of the wheel-shaped workpiece. After the grinding and deburring operation of the wheel-shaped workpiece is completed, the rotary cylinder 201 is started again, and the electric push rod 203 rotates with the rotary cylinder 201 at an angle again, so that the adsorption plate 204 returns to its original position.

[0035] like Figure 3 and Figure 4 As shown, the wheel-shaped workpiece positioning and rotating mechanism 3 includes a reduction motor 300, a reducer 301, and a positioning table 302. The reducer 301 is rotatably connected to the output shaft of the reduction motor 300, and the positioning table 302 is rotatably connected to the reducer 301 through a rotating shaft 303. The positioning table 302 is used to place the wheel-shaped workpiece. After the wheel-shaped workpiece is placed on the positioning table 302, the reduction motor 300 is started. The reduction motor 300 drives the reducer 301 to rotate, and the rotation of the reducer 301 drives the rotating shaft 303 to rotate, which in turn drives the positioning table 302 to rotate. This allows the wheel-shaped workpiece to rotate together with the positioning table 302. As a result, the grinding disc 6 on the adsorption plate 204 can perform overall grinding and deburring of the edge of the wheel-shaped workpiece.

[0036] During the deburring process, the positioning table 302 will rotate under the action of the rotating shaft 303, and the wheel-shaped workpiece will also rotate with the positioning table 302. Therefore, it is necessary to further fix the wheel-shaped workpiece. Since the wheel-shaped workpiece has a round hole in the middle, a limiting post 304 is fixedly installed in the middle of the surface of the positioning table 302. The limiting post 304 is inserted into the round hole of the wheel-shaped workpiece to fix the position of the wheel-shaped workpiece placed on the positioning table 302.

[0037] In actual use, the support column 200 is fixed on the operating table 1, that is, the grinding disc adsorption and flipping mechanism 2 is relatively fixed on the operating table 1. Therefore, it is also necessary to adjust the relative position of the wheel-shaped workpiece positioning and rotating mechanism 3 on the operating table 1 according to the position of the grinding disc adsorption and flipping mechanism 2, so that the grinding disc 6 on the adsorption plate 204 can accurately and efficiently grind the wheel-shaped workpiece. For this purpose, the wheel-shaped workpiece positioning and rotating mechanism 3 also includes a moving component. The moving component includes a moving guide rail 305, a moving slider 306, and a moving slide plate 307. The moving slider 306 is slidably connected to the moving guide rail 305. The moving slide plate 307 is installed on the moving slider 306. The moving slide plate 307 is fixedly connected to the bottom of the reducer 301. The moving slide plate 307 is connected to the driving component that drives it to slide along the moving guide rail 305 with the moving slider 306. Specifically, the driving component includes a driving motor 308 and a driving rod 309. One end of the driving rod 309 is rotatably connected to the output shaft of the driving motor 308, and the other end of the driving rod 309 is fixedly connected to the moving slide plate 307.

[0038] Start the drive motor 308, which drives the drive rod 309 to rotate. This causes the movable slide plate 307 connected to the drive rod 309 to slide along the movable guide rail 305 with the movable slider 306. This allows the reducer 301 connected to the movable slide plate 307 to slide along the movable guide rail 305, so that the wheel-shaped workpiece can be moved to the position where the grinding disc 6 on the adsorption plate 204 of the grinding disc adsorption and flipping mechanism 2 can be used to grind and remove burrs.

[0039] In practical use, to improve the efficiency of deburring, the grinding disc feeding mechanism 4 is used to convey the grinding discs 6.

[0040] Specifically, such as Figure 5 and Figure 6As shown, the grinding disc feeding mechanism 4 includes a longitudinal linear module 400, a longitudinal slider 401, a support plate 402, and a storage slot 403. The longitudinal linear module 400 passes through the operating table 1. The longitudinal slider 401 is slidably connected to the longitudinal linear module 400. One end of the support plate 402 is fixedly connected to the longitudinal slider 401 so that the support plate 402 moves up and down along the longitudinal linear module 400 with the longitudinal slider 401. The other end of the support plate 402 extends into the storage slot 403. Several grinding discs 6 are stacked in the storage slot 403 along the height direction, and the bottommost grinding disc 6 is placed on the end of the support plate 402 that extends into the storage slot 403. All the grinding discs 6 are stacked in the storage slot 403. After the grinding discs 6 are stacked on one end of the support plate 402 that extends into the storage slot 403, the longitudinal linear module 400 is activated. The longitudinal slider 401 rises along the longitudinal linear module 400, which in turn drives the support plate 402 connected to the longitudinal slider 401 to rise in the storage slot 403, thereby causing the grinding discs 6 on the support plate 402 to rise until the top layer of grinding discs 6 is attracted by the adsorption plate 204. When the adsorption plate 204 needs to attract the next layer of grinding discs 6, the longitudinal slider 401 rises again along the longitudinal linear module 400 until the next layer of grinding discs 6 is attracted by the adsorption plate 204, and so on, until the adsorption plate 204 completes the adsorption of the other layers of grinding discs 6.

[0041] To control the height of the vertical slider 401 as it rises and falls along the vertical linear module 400, a sensing plate 404 is provided on one side of the vertical slider 401, and a sensor switch 405 for sensing the position of the sensing plate 404 is provided on one side of the vertical linear module 400. Specifically, the sensor switch 405 is located at the extreme positions at both ends of the vertical module to prevent the vertical slider 401 from rising or falling indefinitely along the vertical linear module 400. When the vertical slider 401 rises to its highest position along the vertical linear module 400, that is, when the sensor switch 405 at the highest point senses the sensing plate 404, the vertical slider 401 stops rising, thus supporting the vertical linear module 401. When plate 402 stops rising along the storage groove 403, at another angle, the grinding discs 6 on the support plate 402 are exhausted and need to be re-stacked. At this time, the longitudinal slider 401 descends along the longitudinal linear module 400 and when it reaches the lowest position of the longitudinal linear module 400, that is, after the induction switch 405 at the lowest position senses the sensor plate 404, the longitudinal slider 401 stops descending, and the support plate 402 also stops descending along the storage groove 403. New grinding discs 6 are stacked on the support plate 402, and the longitudinal slider 401 rises again to complete the conveying of the grinding discs 6. This process is repeated to realize the feeding and conveying operation of the grinding discs 6.

[0042] In actual use, after the grinding disc 6 finishes grinding and deburring the wheel-shaped workpiece, the grinding disc 6 needs to be recycled. Therefore, a grinding disc recycling mechanism 5 is also installed on the operating table 1.

[0043] Specifically, such as Figure 7As shown, the grinding disc recycling mechanism 5 includes a drive motor 500, a side plate 501, a feeding plate 502, and a recycling bin 503. The drive motor 500 is connected to the support column 200 through a connecting block. The feeding plate 502 is connected to the drive motor 500 through the side plate 501. The recycling bin 503 is located below the feeding plate 502. The drive motor 500 pushes the feeding plate 502 to the bottom of the adsorption plate 204 to receive the grinding discs 6 on the adsorption plate 204. The adsorption plate 204 releases the grinding discs 6 on it, and the grinding discs 6 enter the recycling bin 503 under the action of gravity.

[0044] To facilitate the entry of the grinding disc 6 from the feed plate 502 into the recycling bin 503, the feed plate 502 is set at an angle relative to the recycling bin 503, so that the grinding disc 6 can enter the recycling bin 503 along the angle.

[0045] To facilitate adjustment according to actual work needs, a foot cup 7 is provided at the bottom of the operating table 1. The working height of the operating table 1 can be adjusted by adjusting the height of the foot cup 7 relative to the ground.

[0046] It should be noted that this utility model also includes a control system for controlling the operation of the deburring machine, which belongs to the prior art or is well known to those skilled in the art, and will not be described in detail here.

[0047] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
