[0056] The implementation principle of the multifunctional grinding machine of this embodiment is as follows:

[0057] First, the workpiece 600 needs to be installed. The workpiece 600 is placed in the gap between the top plate 5022 and the positioning plate 503, and the electric push rod 502 is started. The connecting plate 5021 and the top plate 5022 are driven by the electric push rod 502 to move toward the positioning plate 503. The workpiece 600 can be clamped by the mutual squeezing of the positioning plate 503 and the top plate 5022.

[0058] Then the operator starts the telescopic cylinder 301 , and drives the flat plate 302 and the grinding cover 303 to move downward through the telescopic cylinder 301 until the grinding belt 3051 of the grinding cover 303 can contact the surface of the workpiece 600 .

[0059] Then start the grinding motor 304, the grinding motor 304 drives the driving pulley 3041 to rotate, the driving pulley 3041 drives the two driven pulleys 3042 to rotate through the belt 3043, the driven pulley 3042 drives the two driving rollers 305 to start rotating in the same direction, the driving roller 305 can drive the surface grinding belt 3051 to rotate, and the grinding belt 3051 can grind the bottom workpiece 600.

[0060] Then the operator starts the driving motor 201, and the driving motor 201 drives the rotating shaft 2012 connected to the output shaft to rotate. The rotating shaft 2012 can drive the synchronous plate 202 connected to the bottom to rotate, and the synchronous plate 202 is connected to the bottom with a synchronous shaft 2031. At this time, the synchronous shaft 2031 drives the synchronous bracket 203 to rotate, and the guide block on the synchronous bracket 203 drives the entire grinding unit 300 to move in a circle, so that the workpiece 600 clamped at the bottom can be ground.

[0061] During the rotation of the synchronous plate 202, the synchronous plate 202 drives the driving gear 2021 at the end to start rotating, and the driving gear 2021 starts to rotate along the positioning gear ring 2022, and finally drives the driving gear 2021 to rotate on itself, and the driving gear 2021 drives the positioning shaft 2023 to rotate, and the positioning shaft 2023 drives the special-shaped turntable 2024 at the bottom to rotate.

[0062] When the protrusions on both sides of the special-shaped turntable 2024 are squeezed and contacted with the baffle 2041, the baffle 2041 drives the movable plate 204 to move, and the movable plate 204 drives the guide block 2042 to slide in the guide groove 2043. The movement of the guide block 2042 can push the insertion rod 2044 to slide into the cavity, and drive the slide plate 2045 to slide synchronously with the rod. The return spring 2046 can be squeezed by the slide plate 2045, and the reset spring 2046 after squeezing is convenient for the later reset operation, and finally can drive the guide block 2042 to move back and forth left and right.

[0063] During the movement of the guide block 2042, the bottom grinding unit 300 can be driven to move left and right as a whole, and the bottom grinding belt 3051 can move left and right on the surface of the workpiece 600, thereby increasing the grinding range and further improving the grinding speed.

[0064] When the grinding unit 300 is moving, the dust collecting unit 400 can move synchronously. The dust collector 4011 in the dust collecting unit 400 can suck the grinding debris through the dust collecting expansion port 4013 and transport it to the temporary storage box 401 through the transport pipe 4012, thereby achieving the purpose of cleaning.

[0065] When the grinding is completed, the position of the sanding belt 3051 is reset by the telescopic cylinder 301, and the positioning plate 503 is pressed. At this time, the positioning plate 503 drives the partition plate 5031 to slide, and squeezes the extrusion spring 5032. The extrusion spring 5032 is used to facilitate the later reset. When the positioning plate 503 is opened, the operator starts to push the electric push rod 502, and the workpiece 600 can be discharged through the top plate 5022, thereby achieving the purpose of unloading.
