Then, after the sleeve ring 24 is sleeved on the top of the rotating rod 26, the rotating rod 26 is rotated, the sleeve ring 24 is vertically moved down by the spiral torque force of the sleeve ring 24 and the rotating rod 26, and the sleeve ring 24 pressurizes the second spring 21 through the sliding block 22; in the process, the bottom surface of the placement block 15 is correspondingly placed at the top of the protruding block 17 at the top of the inner side of the chassis 2, the stabilizing effect of the placement block 15 in the transverse direction is increased through the protruding block 17, and the distance between the outer side surface of the placement block 15 and the inner side surface of the chassis 2 can be adjusted according to the corresponding effect of the placement block 15 and the protruding block 17, and further the stabilizing effect of the sliding block 22 on the vertical direction of the placement block 15 is increased in a threaded connection mode of the collar 24 and the rotating rod 26, so that the placement block 15 is fixed at the top of the inner side of the chassis 2.
The placing grooves 16 with different heights are selected according to the size of the precision device, the pressing frame 20 with the height corresponding to the placing grooves 16 is selected, after the outer side part of the pressing frame 20 is buckled with the placing grooves 16, the pressing frame 20 is placed at the top of the first spring 19, after the precision device is placed at the top of the pressing frame 20, the double-layer outer ring 5 is rotated, the spiral torque force of the double-layer outer ring 5 and the scale bars 4 is further applied to the bottom frame 2 to slide in the limit groove 32 at the top of the placing table 31, and the relative positions of the two placing blocks 15 and the connecting shaft 9 are adjusted according to the scales on the surface of the scale bars 4, so that the center point of a connecting line of the two placing blocks 15 always coincides with the center of the connecting shaft 9. After the double-layer outer ring 5 rotates, the movable ring 6 drives the placing blocks 15 to move, at this time, the two placing blocks 15 are close to each other, the placing grooves 16 on the inner sides of the two placing blocks 15 pressurize the compact device, the inclination of the side walls of the placing grooves 16 enable the precise device to gradually move downwards, and then the precise device is tightly pressed at the top of the pressing frame 20, the pressing frame 20 extrudes the first spring 19, at this time, the relative positions of the precise device and the connecting shaft 9 are guaranteed, and therefore the fixing effect on the precise device is achieved.
After a processing device (such as a grinding wheel) is mounted on the connecting shaft 9, the air cylinder 12 is started, the air cylinder 12 works to drive the lifting rod 11 to move downwards, at the moment, one end of the rotating plate 13 slides in the chute 14, the other end of the rotating plate 13 rotates on the side face of the limiting block 10, at the moment, the limiting block 10 drives the motor 8 to move downwards slowly under the power action of the lifting rod 11, the stability of the limiting block 10 in the vertical direction is improved through the rotating plate 13 and the chute 14, and the shaking condition of the limiting block 10 in the moving process is avoided.
