[0044] The first electric push rod 302 is an existing device, which uses the rotation of a lead screw to achieve expansion and contraction, and its self-structure has a supporting force.

[0045] The combined setting of the guiding inclined surface 307 and the inclined surface guide plate 306 can blow the dust therein to the position of the guiding inclined surface 307 and then drop it for collection. The inclined surface guide plate 306 is an inclined surface arc plate structure that can guide the direction of part of the air flow.

[0046] The transmission housing 309 includes a body 30901, mounting round holes 30902, a first rotating shaft hole 30903, a second rotating shaft hole 30904, and a housing joint surface 30905. The housing joint surface 30905 is fixedly connected to the upper surface of the body 30901. A plurality of mounting round holes 30902 are provided and are opened on the inner surface of the housing joint surface 30905.

The second rotating shaft hole 30904 corresponds to the first shaft hole grinding shaft 505.

[0047] Working principle: Start the first electric push rod 302 to lower the support die 308. Then place the transmission housing 309 in the support die 308. The transmission housing 309 is supported and limited by the support blocks in the support die 308. Then start the first electric push rod 302 to raise the support die 308. The inside of the fixed annular plate 305 is limited by the fixed annular plate 305. Then start the second electric push rod 8 to move the moving bracket 501 downward. At the same time, start the first servo motor 502, the third servo motor 509, the second servo motor 604 and the fifth motor to drive the mounting hole grinding shaft 503, the first shaft hole grinding shaft 505, the second grinding wheel 605 and the second shaft hole grinding shaft 206 to rotate. And at the same time, start the DC motor 601 to drive the ring plate 603 to rotate through the gear 602. Then the moving bracket 501 moves downward to drive the fixed disc 506 to move downward. At the same time, the fixed bracket 7 also moves downward. When the fixed bracket 7 moves downward, the roller contacts the inclined surface of the sliding inclined plate 204, thereby driving the sliding plate 205 to move towards the transmission housing 309. After that, the mounting hole grinding shaft 503 enters the mounting round hole 30902 for grinding, the first shaft hole grinding shaft 505 enters the second rotating shaft hole 30904 for grinding, and the second shaft hole grinding shaft 206 enters the first rotating shaft hole 30903 for grinding. At the same time, the first grinding wheel 507 contacts the inner annular edge at the upper end of the housing joint surface 30905. The first shaft hole grinding shaft 505 rotates to drive the first grinding wheel 507 to grind the inner annular edge at the upper end of the housing joint surface 30905. At the same time, the second grinding wheel 605 contacts the outer annular edge at the upper end of the housing joint surface 30905 and grinds it. After grinding, start the second electric push rod 8 to lift the fixed disc 506 upward by a certain distance so that the grinding shaft leaves the hole to be ground. At this time, the fixed disc 506 does not leave the fixed annular plate 305. At this time, a cavity is formed inside the fixed annular plate 305 and the holes are not blocked. Then start the air supply device. The air supply device is connected to the air delivery pipe 504 to supply air into the fixed annular plate 305. The dust that has not fallen into the storage chamber 301 is blown from the arc surface of the inclined guide plate 306 to the guiding inclined surface 307 and then drops and is blown out of the holes on the transmission housing 309. The dust is blown onto the filter screen 304. The air leaves from the filter screen 304 and the dust is filtered. Then it drops into the sliding cylinder 303 and drops from the sliding cylinder 303 into the storage chamber 301. When cleaning is required, open the sealing door 9 to clean the dust inside. Then start the first electric push rod 302 to move the support die 308 downward and take out the transmission housing 309 inside.

[0048] Embodiment 2:

[0049] The difference between this embodiment and the first embodiment is as follows: When it is necessary to check the surface wear of the mounting hole grinding shaft 503, the first shaft hole grinding shaft 505, and the second grinding wheel 605, the fixed disc 506 can be raised to the highest position for inspection. When it is necessary to inspect the second shaft hole grinding shaft 206, the fixed disc 506 can be moved to the lowest end to extend the second shaft hole grinding shaft 206 for inspection.
