Description

Technical Field

[0001] The utility model relates to the technical field of spare parts processing, in particular to a polishing device for processing automobile spare parts. Background Art

[0002] There are metal particles on the surface of automobile parts after production. These particles are called burrs. They are formed during cutting, grinding, milling and other similar chip cutting processes. To remove burrs on metal precision parts, mechanical processes such as grinding, polishing and other processes with different degrees of automation are used.

[0003] When polishing the end of a tubular part, the outer wall, the inner wall and the outer side of the end all need to be polished. However, when the polishing device in the related art polishes all directions of the end at the same time, it is not convenient to adjust the polishing device according to the different outer diameters and inner diameters of the tubular part, so that the polishing device can only be used for tubular parts with fixed outer diameters and inner diameters. When polishing tubular parts of other specifications, the equipment needs to be replaced, which is not convenient for improving the practicality of the polishing device. Utility Model Content

The adjustment mechanism 26 includes: a second motor 261, which is arranged on the top of the slide plate 25; a grinding disc 262, which is fixedly connected to the output shaft of the second motor 261; a threaded rod 263, which is rotatably connected to the outer wall of the grinding disc 262, and the threaded rod 263 extends to the inside of the grinding disc 262; a turning handle 264, which is fixedly connected to the top of the threaded rod 263; a polishing block 265, which is threadedly connected to the outside of the turning handle 264; a second threaded rod 266, which is rotatably connected to the outer wall of the grinding disc 262, and the threaded rod 266 extends to the inside of the grinding disc 262; a polishing block 267, which is threadedly connected to the outside of the turning handle 264; a turning handle 268, which is fixedly connected to the top of the second threaded rod 266, and a through slot is opened on the grinding disc 262 for the polishing block 265 and the polishing block 267 to move up and down. The outer wall of the support plate 22 is provided with a rubber pad 23.

[0047] When in use, the staff opens the box door 12, sets the tubular part to be polished on the outside of the support plate 22, and starts the motor 1 211. The motor 1 211 drives the screw rod 21 to rotate, and the threaded block 212 threadedly connected to the screw rod 21 gradually approaches the fixed block 213 when the screw rod 21 rotates. When the threaded block 212 moves, the connecting rod 1 221 and the connecting rod 2 222 prop up the support plate 22 outward until the outer wall of the support plate 22 fits the inner wall of the tubular part, completing the support and fixation of the part, and then uses the adjustment mechanism 26 to make corresponding adjustments and polish according to the outer diameter and inner diameter of the tubular part: start the electric push rod 24, the electric push rod 24 pushes the slide plate 25 and the top motor 2 261 gradually approach the part fixed by the support plate 22, until the tube wall of the tubular part is located between the polishing block 1 265 and the polishing block 2 267, and the rotary The first handle 264 is turned to drive the threaded rod 263 to rotate, and the polishing block 265 threadedly connected to the threaded rod 263 moves up and down along the threaded rod 263 until the polishing block 265 is close to the outer wall of the part, and then the second handle 268 is turned to drive the second threaded rod 266 to rotate, so that the polishing block 267 threadedly connected moves up and down until the top of the polishing block 267 abuts against the inner wall of the tubular part, and the adjustment operation is completed. The box door 12 is closed, and the motor 261 is started. The motor 261 drives the grinding disc 262, the polishing block 1 265 and the polishing block 267 to rotate. When rotating, the grinding disc 262 polishes the outer side of the part end, the polishing block 1 265 polishes the outer wall of the part end, and the polishing block 267 polishes the inner wall of the part end. Several places are polished at the same time, which improves the polishing efficiency. The rubber pad 23 increases the friction when the support plate 22 contacts the inner wall of the tubular part, and increases the stability of the part during polishing.

[0048] Embodiment 2

[0049] On the basis of the first embodiment, an auxiliary function is added.

[0050] See also Figure 1-5 The support plate 22 and the rubber pad 23 are both arc-shaped. A telescopic plate 27 is fixedly connected to the through groove on the grinding disc 262 for the polishing block 1 265 and the polishing block 2 267 to move, and the polishing block 1 265 and the polishing block 2 267 pass through the telescopic plate 27. A visualization window 13 is provided on the box door 12.

[0051] The arc shape of the support plate 22 and the rubber pad 23 increases the contact surface with the inner wall of the tubular part, and the fixing effect of the tubular part is better. The telescopic plate 27 is telescopic as the polishing block 1 265 and the polishing block 2 267 are adjusted up and down, and the through groove on the grinding disc 262 is blocked to prevent the debris generated during polishing from entering the through groove and affecting the up and down adjustment of the polishing block 1 265 and the polishing block 2 267. After placing the parts, the staff closes the box door 12 in time and then performs the polishing process to prevent the debris from splashing everywhere during polishing, and the staff can observe the polishing through the visualization window 13.
