Then when the threaded sleeve 26 and the outer tube 27 rotate relatively, the threaded sleeve 26 is connected with the inner screw of the threaded sleeve 26 and then the outer tube 27, so that under the action of threaded connection, the threaded sleeve 26 and the outer tube 27 can transversely displace relatively, the sliding connection of the telescopic groove 35 and the telescopic column 36 prevents displacement from being interfered, when the displacement is to the appointed position, the inner screw of the threaded sleeve 26 is separated, and meanwhile, the plurality of triangular clamping blocks 30 move to the annular groove 34 to lose the limit of the threaded sleeve 26 by the bayonet 29, the structure such as the reciprocating screw 9 connected with the outer part of the threaded sleeve 26 can reset under the action of the spring force, and the bearing ring loses the clamping and fixing state, so that the threaded sleeve can be conveniently taken down;
When the connecting frame 37 pulls the through column 15 to clamp, the ball screw 46 is pulled through the reciprocating frame 42, then the ball screw block 47 is rotated, the first bevel gear 50 and the second bevel gear 51 meshed with the ball screw block 47 can be driven to rotate when the ball screw block 47 rotates, then the locating frame 57 is pushed by the reciprocating screw 59 to enable the locating wheel 58 to approach the bearing ring, the locating wheel 58 contacts the bearing ring to complete locating work, at the moment, although the reciprocating frame 42 continuously moves along with the multifilament block 10, the locating work can be kept due to the arrangement of the fourth spring 48 and the spring rod 49, then the reciprocating screw 9 does not rotate any more in the process, locating work in the polishing process is not affected, when the locating wheel 58 moves in a locating mode by means of the first bevel gear 50 and other structures, the fourth bevel gear 53 and the first bevel gear 50 can be synchronously rotated by means of the transmission connecting rod 54, then the third bevel gear 52 and the reciprocating screw 59 can be synchronously moved to the appointed position near the bearing ring by the locating wheel 58, the locating wheel 58 can accurately move to complete locating and fix the locating work of the grinding machine 2, polishing work by workers is convenient, and meanwhile, and when the grinding machine 2 is reset, the grinding work can be prevented from being accidentally removed when the grinding machine is not in time.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
