Figure 2 、 3As shown, by rotating the double-headed screw rod 1102, the rotation of the double-headed screw rod 1102 can drive the movement of the threaded sleeve 1103. At the same time, a stabilizing rod 1104 is connected to the side of the threaded sleeve 1103 near the bottom. Through the action of the stabilizing rod 1104, the threaded sleeve 1103 can be limited, so that the threaded sleeve 1103 can move on the double-headed screw rod 1102. At the same time, by pulling the limiting rod 1107, the limiting rod 1107 is separated from the limiting groove 1106, so that the sliding rod 1105 can be pushed. The movement of the sliding rod 1105 can drive the movement of the splint 1110, so that the splint 1110 can clamp parts of different sizes, thereby ensuring the stability of the parts during grinding. , thereby improving the grinding efficiency of parts.

[0033] Working principle: Before using this high-precision grinding machine, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5As shown, first, when the grinding device 10 needs to be replaced, the limiting plate 1307 on the fixed rod 1306 is rotated so that the limiting plate 1307 no longer limits the pressing rod 1302, and the clamping rod 1304 moves under the action of the second spring 1305. The movement of the clamping rod 1304 can drive the movement of the extrusion block 1303, and the movement of the extrusion block 1303 can drive the movement of the pressing rod 1302, so that the clamping rod 1304 moves under the action of the second spring 1305. After reaching a certain position, the clamping rod 1304 is completely separated from the clamping groove 14, so that the grinding device 10 can be buckled out, so that a different grinding device 10 can be replaced. When the grinding device 10 is installed, after the grinding device 10 is clamped in the groove 12, the pressing rod 1302 is pressed, so that the pressing rod 1302 will squeeze the squeezing block 1303. After the squeezing block 1303 is squeezed, the clamping rod 1304 is driven to move, and the movement of the squeezing block 1303 will also The second spring 1305 is squeezed, so that the second spring 1305 is deformed. At the same time, after the pressing rod 1302 pushes the extrusion block 1303 to move to a certain position, the card rod 1304 is engaged with the card slot 14, and the height of the pressing rod 1302 is just lower than the height of the limit plate 1307. Then, by rotating the limit plate 1307, the limit plate 1307 is rotated 90 degrees, so that the limit plate 1307 will limit the pressing rod 1302.

At the same time, the third spring 1308 is a compression spring in the prior art, and the elastic force of the compression spring is relatively large. At the same time, the second spring 1305 is a rubber composite spring in the prior art, and the elastic force of the rubber composite spring is relatively small. Therefore, by replacing different grinding devices 10, the work efficiency of the staff can be improved, and the grinding efficiency and accuracy of the parts can also be improved.

[0034] Secondly, after placing the parts on the placement plate 2, by rotating the double-headed screw rod 1102, the rotation of the double-headed screw rod 1102 can drive the movement of the threaded sleeve 1103. At the same time, a stabilizing rod 1104 is connected to the side of the threaded sleeve 1103 near the bottom. Through the action of the stabilizing rod 1104, the threaded sleeve 1103 can be limited, so that the threaded sleeve 1103 can move on the double-headed screw rod 1102. At the same time, by pulling the limiting rod 1107, the limiting rod 1107 is separated from the limiting groove 1106, so that the sliding rod 1105 can be pushed to drive the movement of the splint 1110. The movement allows the splint 1110 to clamp parts of different sizes, thereby ensuring the stability of the parts during grinding, thereby improving the grinding efficiency of the parts. After the slide bar 1105 and the splint 1110 are moved to the appropriate position, the limiting rod 1107 is loosened so that the limiting rod 1107 returns to its original position under the action of the first spring 1109, so that the limiting groove 1106 is re-engaged, thereby completing the limitation of the slide bar 1105. At the same time, the splint 1110 is made of rubber, so that the friction between the splint 1110 and the parts is large, thereby achieving the goal of clamping parts of different sizes, thereby improving the flexibility of the device.
