The conveyor frame 2 is used to convey a housing 3, which has been disclosed in publication number CN211592249U. Two center positioning mechanisms 23 are symmetrically mounted on the conveyor frame 2, and a lifting and polishing mechanism is provided at the center of the two center positioning mechanisms 23. The lifting and polishing mechanism is used to polish the inner hole of the housing 3. Supports 11 are symmetrically mounted on the top of the operating table 1, and a mounting plate 13 is fixedly mounted between the two supports 11. An annular guide rail 12 is provided on the outer side of the mounting plate 13. The annular guide rail 12 has the same circumferential shape as the housing 3. A side deburring mechanism 15 is slidably connected to the annular guide rail 12. The side deburring mechanism 15 includes a cylinder 151 fixedly mounted on a U-shaped slider 121. A push plate 152 is fixedly mounted on the piston rod of the cylinder 151. The push plate 152 is slidably connected to the U-shaped slider 121 to ensure its movement stability. A rotary motor 153 is fixedly mounted at the bottom center of the push plate 152. A convex polishing disc 154 is fixedly mounted on the output shaft of the rotary motor 153. Push rods 155 are fixedly mounted on both sides of the rotary motor 153. An adjusting plate 156 is fixedly mounted at the bottom of the piston rod of each push rod 155. The adjusting plate 156 is sleeved on the output shaft of the rotary motor 153. A polishing disc 161 is rotatably mounted on the bottom of the adjusting plate 156. The polishing disc 161 is sleeved on a convex polishing disc 154, and a gear ring 157 is fixedly mounted on the outer circumferential surface of the polishing disc 161. The output shaft of the rotary motor 153 is secured above the adjusting plate 156. A gear 158 is connected to a gear, which meshes with the gear. A connecting shaft 159 is fixedly mounted on the bottom of the gear, and the connecting shaft 159 passes through the adjusting plate 156 and connects to a gear 160. The bottom of the gear 160 is connected to the top of the polishing disc 161 via a rotating shaft for support. The connecting shaft 159 and the adjusting plate 156 are connected by a bearing to ensure that the connecting shaft 159 can rotate without sliding up and down. The gear 160 meshes with a gear ring 157. With the above structure, the push rod 155 can be activated to push the adjusting plate 156 up and down, thereby driving the polishing disc 161 up and down, adjusting the height between the convex polishing disc 154 and the polishing disc 161, facilitating the polishing of shells of different thicknesses. During the adjustment process, the gear ring 157 and the gear 160 do not separate and do not affect their rotation.

[0031] A U-shaped slider 121 is slidably connected to the annular guide rail 12. A drive motor 122 is fixedly installed on one side of the U-shaped slider 121. A rotating shaft 125 is fixedly installed on the output shaft of the drive motor 122. The rotating shaft 125 extends into the U-shaped slider 121 and is rotatably connected to the U-shaped slider 121. A gear 124 is sleeved on the rotating shaft 125. The gear 124 meshes with a rack 123 provided at the bottom of the annular guide rail 12, which facilitates driving the U-shaped slider 121 to slide on the annular guide rail 12.

[0032] The rotary motor 153 is started, which drives the convex polishing disc 154 to rotate, and at the same time drives the gear three 158 to rotate. The gear three 158 drives the gear to rotate, and the gear drives the gear four 160 to rotate through the connecting shaft 159. In turn, the gear ring 157 drives the polishing disc to rotate, and then the convex polishing disc 154 and the polishing disc polish the sides and top and bottom edges of the housing 3, and slide along the annular guide rail to perform annular polishing. With this structure, the rotary motor 153 drives the convex polishing disc 154 and the polishing disc to rotate synchronously to remove burrs.

[0033] A cylinder 14 is fixedly mounted on the bottom of the mounting plate 13, and a suction cup 16 is fixedly mounted on the piston rod of the cylinder 14. By adsorbing and fixing the housing from above, and with the support of the central positioning plate 213, it is convenient to polish the holes and sides of the housing simultaneously.

[0034] The top of the conveyor frame 2 is provided with two conveyor belts 21, and a lifting and polishing mechanism is provided at the center of the two conveyor belts 21. The lifting and polishing mechanism includes a second cylinder 211 fixedly installed on the conveyor frame 2. A support plate 212 is fixedly installed on the piston rod of the second cylinder 211. A support rod 27 is fixedly installed on the top of the support plate 212. A center positioning plate 213 is fixedly installed on the top of the support rod 27. The area of ​​the center positioning plate 213 is smaller than the area of ​​the housing 3. The housing is first raised to facilitate the center positioning mechanism 23 on both sides to drive it for center positioning.

[0035] The top of the lifting support plate 22 is also rotatably mounted with multiple threaded sleeves 28. The threaded sleeves 28 are internally threaded with threaded rods 26. A polishing roller 25 is fixedly mounted on the top of the threaded rods 26. The polishing roller 25 is inserted into the center positioning plate 213, which can ensure that the center positioning plate 213 will not move during the up and down movement of the polishing roller 25. Each threaded sleeve 28 is fitted with a gear 24. A cylinder 29 is fixedly mounted on one side of the top of the lifting support plate 22. A rack 210 is fixedly mounted on the piston rod of the cylinder 29. The rack 210 is horizontally set and meshes with multiple gears 24.

[0036] Start cylinder 29, which drives rack 210 to reciprocate. Simultaneously, multiple gears 24 drive threaded sleeve 28 to rotate. Threaded sleeve 28 drives internal threaded rod 26 to rotate and rise. This rotation and rise, in turn, drives polishing roller 25 to rotate and rise, and simultaneously polishes the inside of the hole in housing 3.

[0037] A center positioning mechanism 23 is provided on both sides of the inner wall of the conveyor frame 2, located on both sides of the lifting and polishing mechanism. The center positioning mechanism 23 includes a push rod 231, an arc-shaped rail 232 fixedly mounted on the telescopic rod of the push rod 231, a pin 233 fixedly mounted at the center of the arc-shaped rail 232, and telescopic springs 236 on both sides of the pin 233. The telescopic springs 236 are located in the grooves of the arc-shaped rail 232, and an arc-shaped tube can be installed in the telescopic spring 236 for support. A slider 235 is fixedly mounted at the end of the telescopic spring 236, and a limiting shaft 237 is fixedly mounted on the slider 235. Two limiting discs 234 are symmetrically mounted on the limiting shaft 237. Rubber posts 238 are provided at both ends of the limiting shaft 237, and the limiting discs 234 are fixedly mounted on the inner side of the rubber posts 238. A servo motor is fixedly installed inside the conveyor frame 2. A bidirectional threaded rod is fixedly installed on the output shaft of the servo motor. The bidirectional threaded rod is connected to the push rod 231 through a threaded sleeve. The push rod 231 is a U-shaped rod, and the conveyor frame 2 is provided with a groove for the push rod 231 to move, so that it will not conflict with the conveyor belt during its movement.

[0038] The servo motor is started, which drives the bidirectional threaded rod to rotate. The bidirectional threaded rod moves through the threaded sleeve, which in turn drives the push rod 231 to move inward, pushing the arc-shaped rail 232 to move towards the center. When the limiting shaft 237 contacts the housing, it compresses the telescopic spring 236. Through the setting of the limiting shaft 237 and the telescopic spring 236, the irregular sides of the housing are limited. At the same time, the height of the housing is limited by the limiting plate 234, which facilitates its center positioning.

[0039] The working principle of this invention is as follows: The casing 3 of the odometer is placed on two conveyor belts 21 for conveying. When it is conveyed to the center positioning mechanism 23 and is located on the center positioning plate 213, the cylinder 211 is activated to drive the support plate 212. The support rod 27 lifts the center positioning plate 213, thereby lifting the casing 3. Then, the center positioning mechanism 23 is driven to move, pushing the casing 3 to the center position, so that the hole of the casing 3 corresponds to the polishing roller 25 and the edge of the casing 3 corresponds to the side deburring mechanism, which facilitates the subsequent polishing of its hole and side. At this time, the cylinder 14 is activated to drive the suction cup 16 to descend and suck up the casing 3. Then, the center positioning mechanism 23 is released.

[0040] Start cylinder 29, which drives rack 210 to reciprocate. Simultaneously, multiple gears 24 drive threaded sleeve 28 to rotate. Threaded sleeve 28 drives internal threaded rod 26 to rotate, rotating and lifting. This rotation and lifting of polishing roller 25, simultaneously polishing the inside of the hole in housing 3. At the same time, start cylinder 151 to push push plate 152 to move, so that convex polishing disc 154 and polishing disc 161 come into contact with the side and top and bottom edges of housing 3.

[0041] Finally, the rotary motor 153 is started, which drives the convex polishing disc 154 to rotate, and at the same time drives the gear three 158 to rotate. The gear three 158 drives the gear to rotate, and the gear drives the gear four 160 to rotate through the connecting shaft 159. In turn, the polishing disc is driven to rotate through the gear ring 157. Then, the convex polishing disc 154 and the polishing disc polish the sides and top and bottom edges of the housing 3, and slide along the annular guide rail to perform annular polishing.

[0042] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention.
