One end of the third elastic spring 315 is fixedly connected to the upper inner wall of the limiting groove 31, and the other end of the third elastic spring 315 is fixedly connected to the movable plate 34;

[0039] The present invention is provided with a base plate 1. The measuring rod of micrometers of different sizes is clamped in the positioning groove 22 through the positioning groove 22 opened on the base plate 1, the first elastic spring 25 and the clamping block 24. The anti-slip pad 26 on the clamping block is made of rubber and is used to increase the friction with the measuring rod when clamping the measuring rod, and together with the elastic force of the first elastic spring 25 rebounding, it prevents the measuring rod from moving during grinding. The lower end of the measuring rod is inserted through the lower limiting hole 27 for limiting to prevent deviation;

[0040] The present invention is provided with a rotating plate 29. By engaging the tooth groove 28 opened at the lower end of the base plate 1 with the rotating gear 210 on the inner wall of the base 1, the rotation of the base plate 1 can be controlled by rotating the handle 212 to drive the measuring rod to rotate. Multiple measuring rods can be clamped. After the grinding process, the base plate 1 is rotated to replace the measuring rod for processing, which increases the efficiency. Multiple fixing grooves 211 are provided on the rotating plate 29, and are clamped and fixed by the second elastic spring 213 and the limiting beads 214 on the four inner walls of the base 1. When rotating to the next fixing groove 211 each time, the second elastic spring 213 pops out the limiting beads 214 to be clamped with the fixing groove 211 to perform a braking process on the rotating plate 29 and control the angle of a single rotation;

[0041] The present invention is provided with a baffle 32. By rotating the adjusting rod 33, the up and down sliding of the baffle 32 is controlled to adjust the position, which is used to control the sliding distance of the movable plate 34 in the limiting groove 31 to control the depth of the grinding process and the grinding size, so as to prevent the measuring rod from being over-ground into a waste product. The grinding blade 313 and the slider 312 are provided. The slider 312 can slide along the cutting tool set 311 and is fixed by the fixing knob 314 after adjustment to prevent movement, so as to adjust measuring rods with different outer diameters and perform grinding processing on their upper ends.

[0042] During use, according to the outer diameter of the measuring rod, the sliding adjustment block 24 slides in the first chute 23 to squeeze the first elastic spring 25. The lower end of the measuring rod is inserted into the limiting hole 27, and at the same time, the first elastic spring 25 pops out the block 24. The three blocks 24 clamp the measuring rod at the same time. The anti-slip pad 26 at one end of the block 24 is arranged in an arc shape, which can better wrap the surface of the measuring rod, increase the contact area, and improve the anti-slip effect. At the same time, multiple measuring rods are installed in the remaining positioning grooves 22 in the above manner. Rotate the handle 212 to drive the rotating gear 210 to rotate. The rotation of the rotating gear 210 drives the tooth groove 28 to rotate to control the rotation of the bottom plate 21, so that the positioning groove 22 rotates to change the position of the measuring rod, and at the same time drives the lower rotating plate 29 to rotate, pushing the limiting bead 214 to squeeze the second elastic spring 213. The rotating plate continues to rotate until the next fixing groove 211 is aligned with the limiting bead 214. The second elastic spring 213 pops out the limiting bead 214 to be engaged with the fixing groove 211 for braking. At this time, there will be a sense of stagnation when rotating the handle, so as to know the rotation angle and prevent over-rotation, resulting in the positioning groove 22 being unable to align with the grinding mechanism 3;

[0043] After aligning the measuring rod in the positioning groove 22 with the grinding mechanism 3 by rotating the handle 212, rotate the adjusting rod 33 to make the baffle 32 slide up and down along the limiting groove 31. Adjust and control the position of the baffle 32 according to the actual length of the measuring rod and the depth to be ground to adjust the final grinding depth. After adjusting the grinding depth, rotate the adjusting fixing knob 314 according to the outer diameter of the measuring rod to loosen the slider 312, and then slide the slider 312 along the cutting tool group 311 to align the outer diameter size to the surface of the measuring rod near the upper end. When the distance between the sliders 312 is smaller than the outer diameter, the upper end and the upper surface of the measuring rod can be ground. After adjusting the grinding size, grasp the fixing knob 314 to fix the slider 312, and then pull the handle 39 to slide downward along the second chute 38, driving the movable plate 34 to slide downward along the limiting groove 31 and pulling the telescopic rod 37 to move downward. At the same time, the servo motor 310 rotates to drive the cutting tool group 311 and the slider 312 to rotate. When the grinding blade 313 in the slider 312 contacts the upper end of the measuring rod, the surface of the measuring rod is ground according to the previously adjusted distance until the movable plate collides with the baffle 32. At this time, the cutting tool group 311 grinds the upper end of the measuring rod, and the upper end and the surface near the upper end of the measuring rod are ground to ensure smoothness. At the same time, the exhaust fan 36 extracts air and sprays it out from the nozzle of the telescopic pipe 37 to cool the slider 312, the cutting tool group 311 and the grinding blade 313, and at the same time blows away the chips generated during processing. After cutting, release the handle 39, and the third elastic spring 315 makes the movable plate 34 rebound and reset. Then rotate the handle 212 to drive the next measuring rod to the grinding mechanism 3 for material replacement processing.
