[0019] A polishing device for producing and processing a shaft sleeve comprises a base 1, wherein a clamp 3 and an L-shaped hanging frame 2 are arranged on the upper surface of the base 1, a lifting device 4 is fixedly installed on the lower surface of the top of the L-shaped hanging frame 2, a long-axis grinding motor 5 is fixedly installed on the lower end of the lifting device 4, a grinding mechanism 6 is detachably installed on the lower end of the output shaft 51 of the long-axis grinding motor 5, and two sliding rods 7 (such as Figure 1As shown, a stopper is provided on the top of the slide bar 7), a cover plate 8 is fixedly installed between the lower surfaces of the two slide bars 7, a through hole 81 is penetrated through the center position of the upper surface of the cover plate 8, the output shaft 51 penetrates through the through hole 81, the grinding mechanism 6 is located below the cover plate 8, a slot 12 is provided on the front surface of the base 1, a collection box 13 is inserted and installed in the slot 12, a collection port 11 is provided between the upper surface of the base 1 and the slot 12, and the collection port 11 is located directly below the grinding mechanism 6;

[0020] It should be noted that if Figure 3 As shown, the grinding mechanism 6 includes a fixed block 61, a mounting groove 611 is provided on the front surface of the fixed block 61, a partition 612 is fixedly installed in the middle of the inner cavity of the mounting groove 611, springs 62 are fixedly installed on the left and right surfaces of the partition 612, an L-shaped movable rod 63 is fixedly installed on the end of the spring 62 away from the partition 612, the end of the L-shaped movable rod 63 away from the spring 62 passes through the outer surface of the fixed block 61, and a grinding wheel 64 is installed on the end of the L-shaped movable rod 63 away from the spring 62, a convex block 65 with a groove on the top is fixedly installed on the upper surface of the fixed block 61, the lower end of the output shaft 51 of the long-axis grinding motor 5 is plugged into the groove of the convex block 65, and a locking bolt 52 is installed between the convex block 65 and the output shaft 51. When replacing the grinding mechanism 6, the locking bolt 52 is removed, and it can be replaced after being separated from the output shaft 51;

[0021] When in use, the L-shaped movable rod 63 is pulled inward to shorten the distance between the two grinding wheels 64 to a distance smaller than the inner diameter of the sleeve, and then the long-axis grinding motor 5, the output shaft 51 and the grinding mechanism 6 are driven by the lifting device 4 to move downward and extend into the sleeve.

When the clamp 3 is used to clamp and fix the shaft sleeve, the shaft sleeve is first placed between the V-shaped plate 31 and the fixed plate 32, and then the hydraulic telescopic rod 33 is driven to extend, driving the fixed plate 32 to move toward the V-shaped plate 31, so that the shaft sleeve is clamped on the through-opening 81 of the base 1 by the cooperation of the V-shaped plate 31 and the fixed plate 32, and after the shaft sleeve is fixed, it is just located directly below the grinding mechanism 6.

[0023] Specifically, if Figure 1 As shown, the lifting device 4 includes a hydraulic lifting column 41 fixedly installed on the lower surface of the top end of the L-shaped hanging frame 2, a work frame 42 is fixedly installed on the lower surface of the hydraulic lifting column 41, and four directional rods B43 are fixedly installed on the upper surface of the work frame 42.
