The ball screw 7 is connected to the connecting block 803 by a through thread, which drives the feeding assembly 8 to slide along the slide groove 5. First, the bearing rollers to be ground are moved to the bottom of the rough grinding assembly 11. The first lifting frame assembly 9 drives the rough grinding assembly 11 to descend and contact the bearing rollers for rough grinding.

The second connecting frame 1004 is installed inside the second telescopic cavity 1002 and is slidably connected to the second column 1001. The second electric telescopic cylinder 1003 is fixedly installed inside the second telescopic cavity 1002, and the telescopic end of the second electric telescopic cylinder 1003 is connected to the second connecting frame 1004.

[0029] The second electric telescopic cylinder 1003 is activated, and its telescopic end drives the second connecting frame 1004 to slide in the second telescopic cavity 1002, thereby realizing the lifting and lowering adjustment of the second connecting frame 1004, so that the fine grinding component 12 is lowered to a suitable height, allowing the sand belt grinding roller 1203 to approach the contact bearing roller.

[0030] The precision grinding assembly 12 includes a second mounting plate 1201, a second mounting groove 1202, a sanding belt grinding roller 1203, a second drive cavity 1204, a third motor 1205, and a second belt pulley transmission mechanism 1206.

[0033] During the grinding process, the exhaust fan 15 is activated to generate a strong suction force, which draws out the dust around the feeding component 8. The dust generated during grinding is then drawn into the dust filter box 14 through the connecting pipe 16, thus removing grinding debris in real time, preventing secondary scratches, and purifying the working environment.

[0034] A support column 2 is fixedly installed under the processing table 1. There are four support columns 2 installed at the four corners of the processing table 1. A rubber seat 3 is fixedly installed under the support column 2.

[0035] The support column 2 supports the processing table 1, and the rubber seat 3 below the support column 2 can reduce the vibration generated during the operation of the equipment, ensuring the stability of the equipment and the grinding accuracy.

[0036] Working principle: See Figure 1 and Figure 3 As shown, the commercial new energy vehicle bearing roller to be ground is placed on the support roller 802. The first motor 4 is started, driving the ball screw 7 to rotate. Since the ball screw 7 is connected to the connecting block 803 by a through thread, the connecting block 803 will slide along the slide groove 5, so that the placement seat 801 moves to the bottom of the rough grinding component 11 first. See Figure 1 , Figure 4 and Figure 6 As shown, the first electric telescopic cylinder 903 drives the first connecting frame 904 to slide in the first telescopic cavity 902, so that the rough grinding component 11 is lowered to a suitable height, allowing the oilstone grinding roller 1103 to contact the bearing roller. The second motor 1105 is turned on to drive the first belt pulley transmission mechanism 1106 to drive the oilstone grinding roller 1103 to rotate through the first belt pulley transmission mechanism 1106, so as to perform rough grinding on the bearing roller. See Figure 1 , Figure 5 and Figure 7 As shown, after the rough grinding is completed, the first electric telescopic cylinder 903 is driven to reset the first lifting frame assembly 9, and then the second electric telescopic cylinder 1003 is driven to drive the second connecting frame 1004 to slide in the second telescopic cavity 1002, so that the fine grinding assembly 12 is lowered to a suitable height, allowing the abrasive belt grinding roller 1203 to contact the bearing roller. The third motor 1205 is turned on to drive the second belt pulley transmission mechanism 1206, which drives the abrasive belt grinding roller 1203 to rotate, and performs fine grinding on the bearing roller. See Figure 1 and Figure 2 As shown, during the grinding process, the exhaust fan 15 is turned on to generate a strong suction force, which draws out the dust around the feeding component 8. The dust generated during grinding is then sucked into the dust filter box 14 through the connecting pipe 16, which removes grinding debris in real time, prevents secondary scratches, and purifies the working environment.

[0037] It should be noted that the first motor 4, control panel 6, first electric telescopic cylinder 903, second electric telescopic cylinder 1003, second motor 1105, third motor 1205 and exhaust fan 15 mentioned above can be powered by existing operating techniques. Whether the power supply is provided by the power supply component or by the external wire, it is all a conventional operating technique and will not be described in detail here.

[0038] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
