Description

Technical Field

[0001] This invention relates to the field of automotive wheel hub processing technology, and in particular to a deburring machine suitable for processing automotive wheel hubs of various sizes. Background Technology

[0002] Car wheel hubs are important components connecting car wheels to the car body. Their main functions include bearing the weight of the vehicle and various working loads, providing a mounting reference for the tires, and enhancing the appearance of the car body. Wheel hubs are generally manufactured by casting, forging, and welding. Among them, casting is widely used due to its advantages of high production efficiency and high forming rate of complex wheel hubs. Wheel hubs formed by casting often have some defects such as burrs and sharp edges on the surface. In order to ensure the normal use of the wheel hub, it is necessary to deburr it.

[0003] Existing deburring technologies typically only use grinding rollers to deburr the edges of the wheel hub. Furthermore, the area of ​​contact between the grinding roller and the wheel hub remains constant during operation. Deburring is a process that consumes a large amount of raw materials. If a localized area of ​​the grinding roller is to operate for an extended period, the amount and rate of material consumption in that area will inevitably be extremely high. Consequently, the outer diameter of the grinding roller will decrease, preventing it from making proper contact with the wheel hub and thus reducing the effectiveness of deburring the wheel hub. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology in the above-mentioned technical background, the present invention provides a deburring machine suitable for processing multi-size automobile wheel hubs.

[0005] The technical solution is as follows: A deburring machine suitable for processing multi-size automotive wheel hubs includes a frame, a support fixedly connected to the frame, a hydraulic push rod mounted on the frame, a movable rod fixedly connected to the telescopic end of the hydraulic push rod, uniformly arranged bosses on the movable rod, a first gear slidably connected to the movable rod via a ring, a support rod slidably connected to the side of the first gear near the support, a limit plate fixedly connected to the end of the support rod away from the first gear, a first groove provided on the limit plate, a first movable component slidably connected in the first groove, a mirror-arranged first protrusion provided on the side of the first movable component near the limit plate, the first protrusion engaging with the first groove, a mirror-arranged mounting seat provided on the first movable component, an electric rotating shaft mounted on the mirror-arranged mounting seats, a grinding roller provided on the electric rotating shaft, a power mechanism for causing relative movement between the movable rod and the support rod provided on the side of the frame away from the support, and a clamping mechanism for clamping the wheel hub provided in the middle of the frame.

The second shells on the same horizontal plane and away from the frame are all slidably connected to pressure plates. The second shells on the same horizontal plane and close to the frame are all slidably connected to clamping members. The clamping members are slidably connected to adjacent second shells. The clamping members are slidably connected to guide shells. The guide shells are fixedly connected to a telescopic rod on the side close to the support. The telescopic end of the telescopic rod is fixedly connected to a bottom block, which contacts and engages with the support.

[0010] Preferably, the opposing sides of the mirror-arranged clamping members are provided with mirror-arranged protrusions for clamping the wheel hub.

[0011] Preferably, the frame is slidably connected to a second moving member, which is limited in engagement with an adjacent boss on the moving rod.

A second elastic element is fixedly connected between the second moving member and the moving rod. An extrusion shell is fixedly connected to the side of the limiting member away from the first gear. A fixing member is fixedly connected to the side of the third moving member close to the first gear. A rotating ring is rotatably connected to the fixing member, and the rotating ring is in a transmission engagement with the first gear. A second sliding ring is slidably connected to the side of the first gear close to the limiting member, and the second sliding ring is rotatably connected to the limiting member. A third elastic element is fixedly connected between the second sliding ring and the first gear. A mirror-arranged limiting groove is provided on the side of the first gear close to the support rod. A second protrusion is provided on the side of the support rod close to the first gear. The limiting groove slides and is limited in engagement with the second protrusion on the support rod.

[0012] Preferably, the device further includes a compensation mechanism for causing relative movement between the grinding roller and the first moving member. The compensation mechanism is located on the side of the first moving member away from the limiting plate. The compensation mechanism includes an intermediate sleeve, which is fixedly connected to the electric rotating shaft. The mounting base is slidably connected to the first moving member. A mirror-arranged first plate is fixedly connected to the intermediate sleeve. The first plate is slidably connected to the grinding roller. A mirror-arranged second plate is fixedly connected to the grinding roller. The second plate is slidably connected to the intermediate sleeve. Uniformly arranged cavities are provided between the intermediate sleeve, the grinding roller, the mirror-arranged first plate, and the mirror-arranged second plate. An oil supply assembly is provided on the side of the limiting plate away from the first moving member to cause relative movement between the mounting base and the first moving member.

[0013] Preferably, the uniformly arranged cavities are all filled with a transmission medium, and the cavities arranged in opposite directions are filled with the same transmission medium, which is used to cause relative movement between the grinding roller and the intermediate sleeve.

[0014] Preferably, the oil supply assembly includes a fixing rod, which is fixedly connected to the side of the limiting plate away from the first moving member. The fixing rod is fixedly connected to an intermediate tank. The first moving member has a cavity. Both the intermediate tank and the cavity are filled with a transmission medium.

An elastic element is fixedly connected between the mounting base and the first moving member. The intermediate tank and the cavity are connected by an intermediate pipe. The intermediate pipe is fixedly connected to the first moving member. The intermediate tank and the grinding roller are connected by uniformly arranged connecting pipes.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: The present invention limits the first protrusion on the first moving member through the first groove, causing the grinding roller to reciprocate during the deburring process of the hub edge. This results in the grinding roller being consumed evenly, thereby extending its service life. Simultaneously, it prevents excessive wear in localized areas during normal operation of the grinding roller, which would reduce its deburring effect on the hub edge. Furthermore, the arc-shaped groove on the first groove and the second through groove on the limiting frame jointly limit adjacent first protrusions on the first moving member, causing the first moving member to deflect, which in turn causes the grinding roller to deflect. This deflected grinding roller is then used to chamfer the hub edge, preventing damage from the grinding roller and hub. The unchanged included angle between the edges leads to incomplete burr removal, thus affecting subsequent processes of the wheel hub. By using opposing clamping components to automatically clamp and center the wheel hub, the number of operation steps for workers is reduced, and work efficiency is improved. At the same time, it also eliminates the inconvenience of traditional clamping fixtures being applicable only to a single wheel hub, thus expanding the applicability of this device. Compressed nitrogen gas is used to cause the intermediate sleeve and the grinding roller to rotate relative to each other, thereby increasing the hydraulic oil in the cavity and moving the grinding roller closer to the wheel hub. This compensates for the wear of the grinding roller due to long-term operation and prevents the worn grinding roller from failing to maintain normal contact with the edge of the wheel hub, thus reducing the effectiveness of deburring the wheel hub edge.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0019] Existing deburring technologies typically only use grinding rollers to deburr the edges of the wheel hub. Furthermore, the area in contact between the grinding roller and the wheel hub remains constant during operation. Over long periods of operation, the wear and tear on this area is extremely high, significantly shortening the roller's lifespan. Consequently, the reduced outer diameter of the grinding roller prevents it from making proper contact with the wheel hub, thus reducing the effectiveness of deburring the wheel hub.

[0020] Example 1: A deburring machine suitable for processing multi-size automotive wheel hubs, such as... Figures 1-7As shown, the device includes a frame 1, a support 2 fixedly connected to the middle of the frame 1, a hydraulic push rod 3 mounted on the upper side of the frame 1, a moving rod 4 fixedly connected to the telescopic end of the hydraulic push rod 3, two vertically evenly arranged bosses on the moving rod 4, the two bosses being located at the middle and lower side of the moving rod 4 respectively, a first gear 5 slidably connected to the middle of the moving rod 4 via a ring, a support rod 6 slidably connected to the lower left side of the first gear 5, a limit plate 7 fixedly connected to the lower end of the support rod 6, a first groove 8 provided on the lower side of the limit plate 7, the first groove 8 consisting of a straight groove and two arc-shaped grooves arranged in a vertical mirror image, with the straight groove located between the two arc-shaped grooves, the arc-shaped grooves used to cause a relative deflection between the first moving member 9 and the limit plate 7, the first moving member 9 slidably connected within the first groove 8, the first moving member 9 having vertically mirror-arranged... The first protrusion is limited by the first groove 8. The radius of the arc groove on the first groove 8 is close to the distance between the two first protrusions on the first moving member 9. The first groove 8 limits the first protrusion, so that the first protrusion moves along the trajectory of the first groove 8. The first moving member 9 is provided with two mounting seats 10 arranged in a mirror image. The two mounting seats 10 are jointly mounted with an electric rotating shaft 11. The electric rotating shaft 11 is provided with a grinding roller 12. The first groove 8 limits the two first protrusions on the first moving member 9, so that the grinding roller 12 performs oblique reciprocating motion, so that the grinding roller 12 is consumed evenly and its service life is extended. The upper side of the frame 1 is provided with a power mechanism for relative movement between the moving rod 4 and the support rod 6. The middle part of the frame 1 is provided with a clamping mechanism for clamping the hub 101.

[0021] like Figures 2-5As shown, the power mechanism includes a motor 1301, which is mounted on the upper side of the frame 1. The output shaft of the motor 1301 is fixedly connected to a rotating shaft 1302. The lower end of the rotating shaft 1302 is fixedly connected to a second gear 1303 that meshes with the first gear 5. A rotating plate 1304 is slidably connected to the upper part of the support rod 6. A limiting member 1305 that is slidably connected to the rotating plate 1304 is splinedly connected to the lower side of the moving rod 4. The limiting member 1305 is limited and engaged with the boss on the lower side of the moving rod 4. The moving rod 4 moves downwards... The side boss supports the limiting member 1305, causing the limiting member 1305 to move together with the moving rod 4. The limiting member 1305 is slidably connected to the rotating plate 1304. A first through groove is provided on the front side of the upper part of the support rod 6, and the rear side of the support rod 6 is an inclined surface that gradually slopes forward from top to bottom. A limiting rod 1306 that is limited and matched with the first through groove is slidably connected in the first through groove on the support rod 6. The limiting rod 1306 is pressed by the support rod 6, causing the limiting rod 1306 to move together with the support rod 6. The positioning component 1305 is provided with a second groove 1307 that engages with the support rod 6. The second groove 1307 is wavy, and its inner side is inclined (i.e., frustum-shaped, with the upper diameter smaller than the lower diameter). The inclined surface of the second groove 1307 presses against the support rod 6, causing the limiting rod 1306 and the positioning component 1305 to move radially relative to each other. Simultaneously, the support rod 6 moves up and down reciprocally. A limiting ring 1308, which engages with the support rod 6, is slidably connected to the front side of the limiting rod 1306. A first elastic element 1309 is fixedly connected between 08 and the limiting rod 1306. The first elastic element 1309 is a spring, which is used to provide pressure to the limiting rod 1306. The limiting rod 1306 is fixedly connected to the limiting frame 1310. The limiting frame 1310 is provided with a second through groove arranged symmetrically at the upper and lower centers. The second through groove is in limiting cooperation with the adjacent first protrusion on the first moving member 9. The second through groove is used to squeeze the adjacent first protrusion on the first moving member 9, so that the first protrusion on the first moving member 9 moves along the first groove 8.

[0022] like Figure 2 and Figure 9As shown, the clamping mechanism includes two first sliding rings 1401 arranged in a left-right mirror image. Both first sliding rings 1401 are slidably connected to the middle of the frame 1. The first sliding rings 1401 are fixedly connected to a first shell 1402, which is filled with a transmission medium, namely hydraulic oil. The opposing sides of the two first shells 1402 are fixedly connected to and connected to two second shells 1403 evenly arranged vertically. The opposing sides of the two upper second shells 1403 are slidably connected to and sealed with pressure plates 1404, and the opposing sides of the two lower second shells 1403 are slidably connected to and sealed with pressure plates 1404. A clamping member 1408 is slidably connected to the adjacent second shell 1403. A guide shell 1406 is slidably connected to the clamping member 1408. A telescopic rod 1405 is fixedly connected to the lower side of the guide shell 1406. A bottom block 1407 is fixedly connected to the telescopic end of the telescopic rod 1405. The bottom block 1407 contacts and engages with the support 2. The support 2 holds the bottom block 1407 against the support, so that the telescopic rod 1405 is subsequently compressed. Two protrusions are provided on opposite sides of the two clamping members 1408, which are arranged in a front-to-back mirror pattern to increase the number of contact points with the wheel hub 101, thereby improving the clamping and centering effect of the wheel hub 101.

[0023] like Figures 2-5 and Figures 8-10 As shown, a second moving member 1501 is slidably connected to the upper part of the frame 1. The second moving member 1501 is limited and engaged with the boss at the middle of the moving rod 4. The boss is used to support the second moving member 1501. A third moving member 1502 is slidably connected to the middle of the second moving member 1501. The third moving member 1502 is provided with two extrusion members arranged in a left-right mirror image. The extrusion members are slidably connected and sealed to the adjacent first shell 1402. A second elastic element 1503 is fixedly connected between the second moving member 1501 and the moving rod 4. The second elastic element 1503 is a spring, which is used to provide pressure to the second moving member 1501. An extrusion shell 1504 is fixedly connected to the lower side of the limiting member 1305. A fixing member 1505 is fixedly connected to the lower side of the third moving member 1502. The lower side of the fixing member 1505 is rotatably connected to a first tooth. The rotating ring 1506 of the gear 5 drives the first gear 5, which is pressed by the rotating ring 1506 to make the first gear 5 mesh smoothly with the second gear 1303. The lower side of the first gear 5 is slidably connected to the second sliding ring 1507, which is rotatably connected to the limiting member 1305. The second sliding ring 1507 and the first gear 5 are fixedly connected to the third elastic element 1508, which is an elastic rubber ring. The lower left side of the first gear 5 is provided with two limiting grooves 1509 arranged in a front-to-back mirror arrangement. The limiting grooves 1509 gradually deflect upward from left to right. The upper side of the support rod 6 is provided with a second protrusion. The limiting grooves 1509 slide and limit the second protrusion on the support rod 6. The limiting grooves 1509 press the second protrusion on the support rod 6, causing the support rod 6 to slide relative to the first gear 5.

[0024] When this device is needed to grind and deburr the outer edge of the hub 101, the hub 101 is placed on the support 2, and then the hydraulic push rod 3 is activated. The telescopic end of the hydraulic push rod 3 begins to drive the moving rod 4 downward. The boss on the lower side of the moving rod 4 gradually loses support for the limiting member 1305. The first gear 5, the limiting member 1305, the extrusion shell 1504, the second sliding ring 1507, and the third elastic element 1508 begin to move downward. The boss in the middle of the moving rod 4 gradually loses support for the second moving member 1501. The second moving member 1501, the third moving member 1502, the second elastic element 1503, the fixing member 1505, and the rotating ring 1506 begin to move downward. During this process, the limiting groove 1509 gradually loses support for the support rod 6. The support rod 6 and its parts begin to move downward. When the extrusion shell 1504 moves downward... After the moving rod 4 contacts the hub 101, the extrusion shell 1504 and the second sliding ring 1507 stop moving downwards. As the moving rod 4 continues to move downwards, the boss on the lower side of the moving rod 4 disengages from the limiting member 1305. The boss in the middle of the moving rod 4 begins to press down on the third moving member 1502. The third moving member 1502 drives the first gear 5 to move downwards together through the fixing member 1505 and the rotating ring 1506. The first gear 5 slides relative to the second sliding ring 1507, and the third elastic element 1508 is compressed. The limiting groove 1509 approaches the second protrusion on the extrusion support rod 6. Then the support rod 6 begins to move backwards. The support rod 6 slides relative to the rotating plate 1304. The support rod 6 drives the limiting ring 1308 to move backwards together. The limiting ring 1308 drives the limiting rod 1306 to move backwards together through the first elastic element 1309.

[0025] During the downward movement of the second moving member 1501, the second moving member 1501 drives the two pressure plates 1404 to move downward together. The pressure plates 1404 drive the adjacent upper second shell 1403 and the adjacent guide shell 1406 to move downward together. The guide shell 1406 drives the adjacent lower second shell 1403 to move downward together through the adjacent clamping member 1408. The two second shells 1403 together drive the adjacent first shell 1402 to move downward together. During the process, the third moving member 1502 drives the two pressing members on it to move downward together. The pressing members and the adjacent first shell 1402 are relatively stationary. When the pressing shell 1504 moves downward to contact the hub 101, the bottom block 1407 also contacts the support 2. As the second moving member 1501 continues to move downward, the telescopic rod 1405 begins to be compressed.

[0026] When the pressure plate 1404 moves downward to contact the hub 101, as the third moving member 1502 continues to move downward, the pressing member on the third moving member 1502 begins to slide downward within the adjacent first shell 1402, simultaneously squeezing the hydraulic oil in the lower part of the adjacent first shell 1402. The hydraulic oil in the lower part of the first shell 1402 enters the lower adjacent second shell 1403, increasing the amount of hydraulic oil in the lower second shell 1403 and squeezing the adjacent clamping member 1408. The two clamping members 1408 begin to move in opposite directions until the hub 101 is completely fixed and centered under the action of the protrusions on the two clamping members 1408. Through the above operation, the hub 101 can be... Automatic clamping and centering reduces the number of steps required by operators, improves work efficiency, and eliminates the inconvenience of traditional clamping fixtures that can only be applied to a single wheel hub 101, thus expanding the applicability of this device. During the process of the two clamping members 1408 moving in opposite directions, the pressing member on the third moving member 1502 creates a negative pressure in the upper part of the adjacent first shell 1402, thereby drawing hydraulic oil from the upper adjacent second shell 1403. Subsequently, the two pressure plates 1404 begin to move in opposite directions and gradually lose pressure on the wheel hub 101 until the two clamping members 1408 completely clamp and fix the wheel hub 101. At this point, the pressure plates 1404 are completely separated from the wheel hub 101.

[0027] As the support rod 6 moves backward, the support rod 6 drives the limiting plate 7 to move backward together. The limiting plate 7 drives the first moving part 9 to move backward together. The first moving part 9 drives the two mounting seats 10 to move backward together. The two mounting seats 10 together drive the electric rotating shaft 11 to move backward together. The electric rotating shaft 11 drives the grinding roller 12 to move backward together. When the grinding roller 12 moves backward to contact the edge of the hub 101, the limiting rod 1306 moves backward to contact the inclined surface inside the second groove 1307. Then, the operator closes the hydraulic push rod 3 and starts the electric rotating shaft 11 and the motor 1301. The electric rotating shaft 11 starts to rotate and grinds the adjacent area of ​​the hub 101 to remove burrs.

[0028] After motor 1301 starts, its output shaft begins to rotate (viewed from above). The output shaft drives the second gear 1303 to rotate clockwise via rotating shaft 1302. The second gear 1303 drives the first gear 5 to rotate counterclockwise. The first gear 5 drives the support rod 6, the second sliding ring 1507, and the third elastic element 1508 to rotate counterclockwise. The second sliding ring 1507 rotates relative to the limiting member 1305. The support rod 6 drives the limiting rod 1306 to rotate counterclockwise. The limiting rod 1306 begins to slide within the second groove 1307 (for example, initially positioned at the center of the wave area on the second groove 1307). As the limiting rod 1306 rotates counterclockwise, the second groove 1307 presses the limiting rod 1306 downwards, causing it to move downwards. The limiting rod 1306 then drives the limiting... As the frame 1310 moves downward together, the first protrusion on the first moving part 9 begins to slide in the adjacent second through groove on the limiting frame 1310. At the same time, the inner inclined surface of the second groove 1307 begins to press the limiting rod 1306, and the limiting rod 1306 begins to move forward. The limiting rod 1306 drives the limiting frame 1310 to move forward together. The two second through grooves on the limiting frame 1310 begin to press the adjacent first protrusion on the first moving part 9. Then, the first moving part 9 begins to slide obliquely downward along the straight groove on the first groove 8. The first moving part 9 drives the electric rotating shaft 11 through the two mounting seats 10 to drive the grinding roller 12 to move obliquely downward together. This makes the outer side of the grinding roller 12 evenly contact the edge of the hub 101, avoiding the same area on the grinding roller 12 from rubbing against the hub 101 for a long time, which would cause excessive wear of that area of ​​the grinding roller 12, thereby reducing the service life of the grinding roller 12 and increasing the grinding cost.

[0029] After the first protrusion on the first moving member 9 moves diagonally downwards into the arc-shaped groove on the lower side of the first groove 8, as the limiting rod 1306 continues to move forward, the second through groove on the front side of the limiting frame 1310 continues to press the first protrusion on the front side of the first moving member 9. Since the first protrusion on the front side of the first moving member 9 has a tendency to move along the arc-shaped groove on the lower side of the first groove 8 at this time, but the second through groove on the rear side of the limiting frame 1310 is still pressing the first protrusion on the rear side of the first moving member 9 (the first protrusion on the rear side of the first moving member 9 is still sliding in the straight groove on the first groove 8), the two first protrusions on the first moving member 9 are horizontal. The distance in the direction begins to decrease (the first protrusion on the front side of the first moving part 9 begins to deflect clockwise with the axis of the rear first protrusion as the center of rotation, viewed from the left), thereby causing the first moving part 9 to deflect clockwise. The first moving part 9 drives the two mounting seats 10 to deflect clockwise together. The two mounting seats 10 together drive the electric rotating shaft 11 and the grinding roller 12 to deflect clockwise together. In this way, the deflected grinding roller 12 is used to chamfer the edge of the hub 101, preventing the burrs from being not completely removed due to the unchanged included angle between the grinding roller 12 and the edge of the hub 101, thus affecting the subsequent processes of the hub 101.

[0030] As the first gear 5 continues to rotate counterclockwise, the support rod 6 continues to move within the second groove 1307. When the support rod 6 moves downward to the lowest point of the wavy area of ​​the second groove 1307, the grinding roller 12 stops rotating clockwise. Then, the support rod 6 begins to move towards the midpoint of the wavy area of ​​the second groove 1307, and the first moving part 9 and its components begin to reset. When the support rod 6 reaches the midpoint of the wavy area of ​​the second groove 1307, the first moving part 9 and its components are completely reset. As the support rod 6 moves towards the highest point of the wavy area of ​​the second groove 1307, the first moving part 9 and its components begin to move diagonally upward. During this process, the first moving part 9 rotates counterclockwise again, and this cycle repeats until the deburring of the hub 101 is completed.

[0031] After deburring the hub 101, the operator shuts off the electric shaft 11 and motor 1301 and starts the hydraulic push rod 3. The telescopic end of the hydraulic push rod 3 drives the moving rod 4 to move upward together. The boss in the middle of the moving rod 4 gradually loses its pressure on the third moving part 1502 and its parts. The boss on the lower side of the moving rod 4 gradually supports the limiting part 1305. Then the moving rod 4 drives the limiting part 1305 and its parts to move upward together. During the process, the pressing part on the third moving part 1502 slides upward along the adjacent first shell 1402. The hydraulic oil in the upper part of the first shell 1402 enters the upper adjacent second shell 1403. The two pressure plates 1404 begin to move and reset in opposite directions. The hydraulic oil in the lower second shell 1403 is drawn into the lower part of the adjacent first shell 1402. The two clamping parts 1408 begin to move and reset in opposite directions. After all parts are completely reset, the operator shuts off the hydraulic push rod 3.

[0032] In Embodiment 1, the grinding roller 12 is fixedly connected to the electric rotating shaft 11, and the mounting base 10 is fixedly connected to the first moving part 9. In Embodiment 2, the mounting base 10 and the first moving part 9 are slidably connected. The grinding roller 12 and the electric rotating shaft 11 are not directly related, but are softly connected through other parts. This allows the relative movement between the grinding roller 12 and the electric rotating shaft 11 to change the distance between the grinding roller 12 and the edge of the wheel hub, thereby changing the friction between them and improving the deburring effect on the wheel hub.

[0033] Example 2: Based on Example 1, as follows Figures 5-7 and Figure 11 As shown, it also includes a compensation mechanism for relative movement between the grinding roller 12 and the first moving member 9. The compensation mechanism is located on the lower side of the first moving member 9. The compensation mechanism includes an intermediate sleeve 1601, which is fixedly connected to the electric rotating shaft 11. The mounting base 10 is slidably connected to the first moving member 9. The intermediate sleeve 1601 is fixedly connected to two first plates 1602 arranged in a left-right mirror image. The first plates 1602 are slidably connected to and sealed with the grinding roller 12. The grinding roller 12 is fixedly connected to two second plates 1603 arranged in a vertical mirror image. The intermediate sleeve 1601 is slidably connected and sealed with the intermediate sleeve 1601. Four cavities are evenly arranged between the intermediate sleeve 1601, the grinding roller 12, the two first plates 1602 and the two second plates 1603. All four cavities are filled with a transmission medium. The transmission medium in the lower left cavity and the upper right cavity is nitrogen, and the transmission medium in the upper left cavity and the lower right cavity is hydraulic oil. This is used to make relative movement between the grinding roller 12 and the intermediate sleeve 1601. The lower side of the limiting plate 7 is provided with an oil supply assembly to make relative movement between the mounting base 10 and the first moving part 9.

[0034] like Figures 5-7 and Figure 11As shown, the oil supply assembly includes a fixing rod 1701, which is fixedly connected to the lower side of the limiting plate 7. The fixing rod 1701 is fixedly connected to an intermediate tank 1702. A cavity 1703 is provided inside the first moving part 9. Both the intermediate tank 1702 and the cavity 1703 are filled with a transmission medium, which is hydraulic oil. The first moving part 9 is slidably connected to two fourth moving parts 1704 arranged in a vertical mirror image. The fourth moving parts 1704 are fixedly connected to the adjacent mounting base 10. An elastic element, which is an elastic rubber block, is fixedly connected between the mounting base 10 and the first moving part 9 to reset the adjacent mounting base 10. The intermediate tank 1702 and the cavity 1703 are connected by an intermediate pipe 1705, which is fixedly connected to the first moving part 9. The intermediate tank 1702 and the grinding roller 12 are connected by two connecting pipes arranged vertically and vertically. The upper connecting pipe is connected to the cavity on the upper left side, and the lower connecting pipe is connected to the cavity on the lower right side.

[0035] To improve the deburring effect on the hub 101, the relative position between the grinding roller 12 and the first moving part 9 is changed by using the relatively rotating grinding roller 12 and the intermediate sleeve 1601. This changes the friction between the grinding roller 12 and the hub 101, preventing the grinding roller 12 from weakening its grinding effect on the hub 101 due to wear, thus reducing the deburring effect. The specific steps are as follows: During the rotation of the electric shaft 11 (e.g., counterclockwise), the electric shaft 11 drives the intermediate sleeve 1601 to rotate counterclockwise together. The intermediate sleeve 1601 drives the two first plates 1602 to rotate counterclockwise together. The left first plate 1602 and the right first plate 1602 begin to compress respectively. Nitrogen gas in the lower left and upper right cavities, through the pressure generated by the compressed nitrogen, drives the grinding roller 12 to rotate counterclockwise. At the same time, the space in the upper left and lower right cavities increases, and hydraulic oil in the intermediate tank 1702 is drawn. The intermediate tank 1702 draws hydraulic oil from the cavity 1703 through the intermediate pipe 1705. The pressure in the cavity 1703 decreases and a negative pressure is generated. Then, the two fourth moving parts 1704 begin to move to the upper right (the limiting plate 7 and its parts are placed at an angle). As the grinding roller 12 gradually moves closer to the edge of the hub 101, the friction between the two gradually increases, that is, the degree of deflection of the intermediate sleeve 1601 relative to the grinding roller 12 gradually increases until the grinding roller 12 stops moving towards the hub 101.

[0036] As the deburring process continues, when the outer side of the grinding roller 12 is worn away, the friction between the grinding roller 12 and the hub 101 decreases. At this point, the intermediate sleeve 1601 begins to rotate clockwise (reset) under the pressure of compressed nitrogen. The intermediate sleeve 1601 drives the two first plates 1602 to rotate clockwise together, reducing the space of the upper left cavity and the lower right cavity, and squeezing the hydraulic oil in this area into the intermediate tank 1702. The hydraulic oil in the intermediate tank 1702 enters the cavity 1703 through the intermediate pipe 1705 and... The two fourth moving parts 1704 are squeezed, and then the fourth moving parts 1704 begin to move to the lower left. The fourth moving parts 1704 drive the adjacent mounting seats 10 to move to the lower left together. The two mounting seats 10 together drive the intermediate sleeve 1601 and the grinding roller 12 to move to the lower left together. This compensates for the wear of the grinding roller 12 due to long-term operation and prevents the worn grinding roller 12 from failing to maintain normal contact with the edge of the hub 101, thereby reducing the effect of deburring the edge of the hub 101.
