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

[0040] The present invention is provided with a rotating plate 29, and a tooth groove 28 is provided at the lower end of the base plate 1 to mesh with a rotating gear 210 on the inner wall of the base 1. The base plate 1 can be rotated by rotating a handle 212 to control the rotation of the base plate 1 to drive the measuring rod to rotate. A plurality of measuring rods can be clamped. After grinding, the base plate 1 can be rotated to replace the measuring rods for processing, thereby increasing efficiency. A plurality of fixed grooves 211 are provided on the rotating plate 29, and the elastic springs 213 on the four inner walls of the base 1 are clamped and fixed with the limiting beads 214. Each time the rotating plate 29 rotates to the next fixed groove 211, the elastic springs 213 pop out the limiting beads 214 to clamp with the fixed grooves 211, and the rotating plate 29 is braked to control the angle of a single rotation.

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

[0042] When in use, the block 24 is slidably adjusted according to the outer diameter of the measuring rod to squeeze the elastic spring 25 in the slide groove 23, and the lower end of the measuring rod is inserted into the limiting hole 27. At the same time, the elastic spring 25 pops out the block 24. The three blocks 24 clamp the measuring rod at the same time. The anti-skid pad 26 at one end of the block 24 is arranged in an arc shape to better wrap the surface of the measuring rod, increase the contact area and improve the anti-skid effect. At the same time, multiple measuring rods are installed in the remaining positioning grooves 22 in the above manner, and the handle 212 is turned 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 drives the rotating plate 29 at the lower end to rotate and push the limiting bead 214 to squeeze the elastic spring 213. The rotating plate continues to rotate until the next fixed groove 211 is docked with the limiting bead 214. The elastic spring 213 pops out the limiting bead 214 and engages with the fixed groove 211 to brake. At this time, there is a sense of stagnation when turning the handle so as to know the rotation angle and prevent the positioning groove 22 from being unable to grind the mechanism 3 to it because of over-rotation.

[0043] After the measuring rod in the positioning groove 22 is aligned with the grinding mechanism 3 by rotating the handle 212, the adjusting rod 33 is rotated to make the baffle plate 32 slide up and down along the limiting groove 31 to adjust the position of the baffle plate 32 according to the actual length of the measuring rod and the required grinding depth to adjust the final grinding depth. After adjusting the grinding depth, the adjusting fixing knob 314 is rotated according to the outer diameter of the measuring rod to loosen the slider 312 and then slide it along the cutting tool assembly 311 to align the outer diameter size of the surface close to the upper end of the measuring rod. When the spacing of the sliders 312 is smaller than the outer diameter size, the surfaces of the upper and lower ends of the measuring rod can be ground. After adjusting the grinding size, grab the fixing knob 314 to fix the slider 312, pull the handle 39 to slide downward along the slide groove 2 38 to drive the movable plate 34 to slide downward along the limiting groove 31 to pull the telescopic rod 37 The servo motor 310 rotates and drives 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 sliding 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 grinds the upper end of the measuring rod and the surface near the upper end to ensure smoothness. At the same time, the exhaust fan 36 draws air from the nozzle of the telescopic tube 37 to cool the slider 312, the cutting tool group 311 and the grinding blade 313, and blows away the debris generated by the processing. After cutting, release the handle 39, the elastic spring three 315 makes the movable plate 34 rebound and reset, and then rotate the handle 212 to drive the next measuring rod to its grinding mechanism 3 for material replacement.
