[0027] When polishing a workpiece, start the second motor 207 to make the bushing rod 209 rotate, so as to achieve clockwise rotation, thereby adjusting the unpolished surface below the grinding machine body 6.

[0028] Further, moving mechanisms 5 are arranged on both sides of the support mechanism 1, a fixing mechanism 4 is arranged above the support mechanism 1, a grinding machine body 6 is arranged above the fixing mechanism 4, and a hydraulic cylinder 7 is arranged above the grinding machine body 6; the support mechanism 1 includes a bottom plate 101, two groups of columns 102 are fixedly installed above the bottom plate 101, a fixing block 104 is fixedly installed between the two groups of columns 102, and a top plate 103 is fixedly installed at the top of the column 102.

[0029] Specifically, columns 102 are fixedly installed at the four corners of the outer top wall of the bottom plate 101, and a top plate 103 is fixedly installed on the outer top wall of the column 102, which plays a role in fixing and carrying the polishing device.

[0030] Further, the moving mechanism 5 includes wheel sleeve boxes 501 fixedly installed at the four corners of the bottom plate 101, a threaded rod 502 is threadedly penetrated through the top of the wheel sleeve box 501, a handle 503 is fixedly installed at the top end of the threaded rod 502, and a universal wheel 504 is fixedly installed at the end of the threaded rod 502 away from the handle 503.

[0031] Specifically, a shock pad is fixedly installed at the bottom of the wheel sleeve box 501. When it is necessary to move the polishing device, turn the handle 503 to rotate the threaded rod 502 to turn out the universal wheel 504 to achieve the purpose of movement. When it is not necessary to move, turn the handle 503 to retract the universal wheel 504 into the wheel sleeve box 501. A shock pad is fixedly installed at the bottom of the wheel sleeve box 501. When the bottom of the wheel sleeve box 501 touches the ground, the shock pad can reduce vibration to make the polishing operation more stable and accurate.

[0032] Furthermore, the fixing mechanism 4 includes a second electric telescopic rod 401 fixedly installed on the inner side of the fixing block 104, and the output end of the second electric telescopic rod 401 is rotatably connected to a turntable 402, and the surface of the turntable 402 is provided with four circular notches, and a rotating sleeve 403 is rotatably connected in each of the four circular notches.

[0033] Specifically, when the second electric telescopic rod 401 is started, the turntable 402 connected to the output end of the second electric telescopic rod 401 will also move. When the rotating sleeve 403 is aligned with the workpiece sleeved on the shaft sleeve rod 209, the second electric telescopic rod 401 is started and adjusted to a suitable position to perform polishing operations.

[0037] Specifically, when the air pump 803 is started, the gas is transported to the gas distribution box 802, and the gas distribution box 802 then transports the gas to the air cushions 801 at different positions through the pipeline, so as to achieve the effect of fixing and clamping the workpiece.

[0038] The technical solution provided by this embodiment is as follows: When using the bushing polishing device for automobile part processing to polish a workpiece, first start the first electric telescopic rod 204 to adjust the bushing rod 209 to a suitable position. If the distance is not enough to insert the workpiece, start the second electric telescopic rod 401 to adjust it to a suitable position. Then, sequentially insert the workpiece to be polished into the bushing rod 209. After insertion, start the second electric telescopic rod 401 to adjust it to a suitable position, and align the rotating sleeve 403 with the workpiece sleeved on the bushing rod 209. If the gap between the workpiece and the bushing rod 209 is too large, start the air pump 803 to deliver gas to the air distribution box 802. The air distribution box 802 delivers the air to the air cushion 801 through a pipeline, so that the air cushion 801 is filled with gas and expands to fill the gap between the workpiece and the bushing rod 209, making it reach a relatively stable state. After adjusting the workpiece, start the hydraulic cylinder 7 to drive the grinding machine body 6 fixedly connected to the extending end of the hydraulic cylinder 7 to move up and down, and adjust it to a position where the workpiece can be ground;

[0039] When polishing the workpiece, starting the second motor 207 and the bushing rod 209 fixedly connected to the output end of the second motor 207 can achieve clockwise rotation, so as to adjust the unpolished surface below the grinding machine body 6. After one workpiece is polished, start the first motor 205. The output end of the first motor 205 is fixedly connected with a rotating shaft 206. Thus, the first motor 205 drives the disc 208 fixedly connected to one end of the rotating shaft 206 to rotate, so as to rotate another unpolished workpiece sleeved on the bushing rod 209 below the grinding machine body 6. When a mobile polishing device is needed, turn the grip 503 to rotate the threaded rod 502 to extend out the universal wheel 504 to achieve the purpose of movement. When movement is not needed, turn the grip 503 to adjust the threaded rod 502 to adjust the universal wheel 504 to be completely retracted into the wheel sleeve box 501.

[0040] Embodiment Two

[0041] Based on Embodiment One, this embodiment includes: The waste collection mechanism 3 includes a sieve plate 301 slidably installed in the column 102. One end of the sieve plate 301 away from the fixed plate 203 is fixedly installed with a handle 302. The sieve plate 301 is divided into upper and lower layers.

[0042] The technical solution provided by this embodiment is as follows: The sieve plate 301 is slidably installed on the column 102 and is directly below the polishing machine body 6. During the polishing operation, most of the debris generated by polishing can be received by the sieve plate 301 below. The sieve plate 301 is divided into upper and lower layers, and debris in different forms can be collected separately. When it is full, it can be pulled out and emptied, avoiding affecting the service life of the machine and reducing production capacity due to failure to clean the residue and waste in time.
