After the nut is inserted into the sleeve rod 601, the sleeve 701 is connected to the left end of the sleeve rod 601, and then the two second sliding bars 705 on the sleeve 701 are pushed out by the arc block 604 on the sleeve rod 601, and the annular stop block 702 slides outwards under the action of the second spring 704, and the anti-sliding block 706 thereon contacts with the side wall surface of the nut sleeved on the left end of the sleeve rod 601, thereby limiting the rotation of the nut on the sleeve rod 601 to a certain extent.

[0035] As attached Figure 1 To Attachment Figure 8As shown, in some embodiments, the nut clamping assembly 4 includes a nut placing plate 401, and a plurality of first bolt mounting holes are opened at the front and rear ends of the upper wall of the nut placing plate 401, and fixing bolts 402 are provided in the first bolt mounting holes, and the installation of the nut placing plate 401 is fixed by the fixing bolts 402.

The lifting connecting plate 302 is provided with a second bolt hole matching the nut placing plate 401. The nut placing plate 401 fixedly connected to the lifting connecting plate 302 by the fixing bolts 402 is driven to rise or fall through the lifting surface of the hydraulic lifting platform 301.

[0037] As attached Figure 1 To Attachment Figure 8 As shown, in some embodiments, the grinding mechanism 2 includes a lifting and grinding rod 202 and two electric slides 201 symmetrically arranged on the base plate 1, the two ends of the lifting and grinding rod 202 are respectively slidably arranged in the two electric slides 201, and a rotating rod is installed in the middle of the upper end of the lifting and grinding rod 202. A second motor is fixedly provided on the outer side of one side of the upper end of the lifting and grinding rod 202, and the rotating end of the second motor is connected to one end of the rotating rod. The rotating rod is equipped with grinding discs 203 matching the number of the sleeve rod 601, and the lifting and grinding rod 202 is driven to slide therein by the electric slide 201, and the grinding disc 203 on the rotating rod is driven to rotate by the rotation of the second motor, and the lifting and lowering of the lifting and grinding rod 202 drives the grinding disc 203 to contact the nut to be polished, thereby performing the grinding work.

[0038] The specific usage and function of this embodiment are as follows: first, select an appropriate nut placement plate 401 according to the angle of the nut, and fix the nut placement plate 401 on the lifting connection plate 302 by fixing bolts 402, and drive the nut placement plate 401 installed on the lifting connection plate 302 to rise to a certain height by the hydraulic lifting platform 301, and insert a nut of a certain length on each sleeve rod 601. At this time, the lower half of the inserted nut should be clamped on the nut limiting groove 403, and the nut limiting component 7 is installed on the right end of the sleeve rod 601 to achieve inward squeezing of the outer side of the nut at the left end of the sleeve rod 601, thereby limiting the rotation of the nut on the sleeve rod 601 to a certain extent. , the sleeve 701 is slid into the left end of the sleeve rod 601 for docking. During the sliding process, the upper wall surface of the arc block 604 on the sleeve rod 601 first contacts the inner wall surface of the annular stop block 702. As the sliding continues, the arc block 604 slides into the inner cavity of the sleeve rod 601 until it reaches the lower end of the T-shaped slider 703. The two first springs 606 on the bottom surface of the arc block 604 release elastic potential energy, driving the arc block 604 to push out the two second slide bars 705 on the sleeve 701. The annular stop block 702 slides outward under the action of the second spring 704, and the anti-sliding block 706 on it contacts the side wall surface of the nut sleeved on the left end of the sleeve rod 601, thereby limiting the nut to a certain extent. The sleeve rod 601 rotates, and the lifting and grinding rod 202 is driven to slide inside it through the electric slide 201, so that the grinding disc 203 reaches the top of the left end of the sleeve rod 601, and the grinding disc 203 on the rotating rod is driven to rotate by the rotation of the second motor. The lifting and lowering of the lifting and grinding rod 202 drives the grinding disc 203 to contact the nut to be polished, and then the grinding work is carried out. After a corner of the nut on it is polished, the nut placing plate 401 installed on the lifting connecting plate 302 is driven to descend through the hydraulic lifting platform 301, so that the nut placing plate 401 is away from the nut, and the nut is not stuck in the nut placing plate 401, and the motor 502 in the casing 501 rotates. The worm 503 is driven to rotate, and then several worm wheels 603 are driven to rotate synchronously, that is, the sleeve rod 601 drives the nut thereon to rotate a certain angle, and the nut placement plate 401 installed on the lifting connecting plate 302 is driven to rise again through the hydraulic lifting platform 301, so that the nut is clamped in the nut limiting groove 403 again, and the corners are polished again. The above process is repeated until all the corners of the nut are polished, and the two T-shaped sliders 703 on the sleeve 701 are pressed to make the arc block 604 enter the inner cavity of the sleeve rod 601. The sliding sleeve 701 makes the nut limiting assembly 7 as a whole detach from the clamping fixation with the sleeve rod 601, and then all the polished nuts are removed.
