[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] refer to Figure 1-2 and Figure 4As shown, the utility model provides a clamping device for bolt processing, comprising: a rotatable chuck 1, a clamping chamber 2 for clamping is opened on one side of the chuck 1, a clamping member and a bolt body are arranged in sequence from the inside to the outside in the clamping chamber 2, the clamping member comprises a plurality of clamping blocks 3, the plurality of clamping blocks 3 are distributed in the clamping chamber 2 in a ring array, a clamping area for plug-in clamping is formed between the plurality of clamping blocks 3, the bolt body comprises a polygonal head 5 and a rod 6, the head 5 is plugged in the clamping area.

[0022] As mentioned above, when using the chuck 1, clamping piece and bolt body provided by the utility model, the chuck 1 is connected to the rotating mechanism through a rotating shaft, and the end of the bolt body is inserted between the multiple clamping blocks 3. At this time, the rod 6 of the bolt body is clamped on the outside of the chuck 1. At this time, the grinding block is placed on the outside of the rod 6, and the rotating mechanism is started to drive the rod 6 to rotate, so as to facilitate the grinding and removal of burrs on the threads on the rod 6 on the grinding block. At the same time, since the bolt body is axially clamped, when the rod 6 approaches and abuts against the grinding block, the head 5 of the bolt body will not leave the clamping area.

[0023] Furthermore, in order to prevent the bolt body from escaping from the clamping area during processing, refer to Figure 2 As shown, the clamping bin 2 is also provided with a magnet 12 for limiting the bolt body, and the chuck 1 is provided with an inner cavity 9 for accommodating the magnet 12; when the head 5 is inserted into the clamping area, the suction force of the magnet 12 limits the head 5 in the clamping area, and when the bolt body is not pushed outward and the pushing force is less than the suction force, the bolt body will not separate from the clamping bin 2, which can improve the stability of the bolt body in the clamping bin 2. When there is no need to process the bolt body, the bolt body is pushed outward and the suction force of the magnet 12 is overcome, so that the bolt body is easily removed.

[0024] Further, in order to facilitate the insertion of the head 5 of the bolt body into the plurality of clamping blocks 3, refer to Figure 2 As shown, a chamfer 13 is provided on the outer side of each clamping block 3 close to one end, and the chamfer 13 is used to guide the end of the bolt body; when the head 5 of the bolt body is close to multiple clamping blocks 3, the head 5 will be guided into the clamping area through the chamfer 13, and when the rod 6 is pressed, it is convenient to insert the head 5 between the multiple clamping blocks 3.

[0025] In the present utility model, combined with Figure 2 As shown, in the chuck 1 of this embodiment, adjusting members connected to different clamping blocks 3 are provided in different directions, and the multiple adjusting members are respectively used to adjust the size of the clamping area.

[0026] Combination Figure 2As shown, the adjusting member includes an adjusting bolt 8, and the outer portion of the chuck 1 is provided with a rotating groove 7, a through hole 14 and a mounting chamber 10 extending into the clamping chamber 2 in sequence, the clamp block 3 is movably installed in the mounting chamber 10, the end of the adjusting bolt 8 is rotatably installed in the rotating groove 7, one end of the adjusting bolt 8 extends into the mounting chamber 10 through the through hole 14, and a threaded hole 11 for accommodating the adjusting bolt 8 is provided on the clamp block 3.

[0027] As mentioned above, when using the adjusting piece provided by the utility model, the end of the adjusting bolt 8 is a hexagonal structure, and its head 5 is rotatably installed on the chuck 1 through the rotating groove 7. One end of the adjusting bolt 8 extends into the mounting bin 10 through the through hole 14, and the clamping block 3 is screwed on the adjusting bolt 8 through the threaded hole 11. The hexagonal structure is adjusted by a tool, thereby driving the adjusting bolt 8 to rotate, and then driving the clamping block 3 to move outward or inward in the mounting bin 10. When the clamping block 3 moves outward, the space of the clamping area can be increased, which is convenient for the equipment to clamp a large-sized bolt body. When the clamping block 3 moves inward, the space of the clamping area can be reduced, which is convenient for the equipment to clamp a small-sized bolt body.

[0028] Further, in order to facilitate the positioning of multiple clamping blocks 3, refer to Figure 3 As shown, the inner wall of the clamping chamber 2 is also provided with multiple polygonal scale lines 4 from the inside to the outside, and one end of multiple clamping blocks 3 can cover the scale lines 4 on the same side. Each polygonal scale line 4 represents the size of a bolt body of a certain size. When one end of multiple clamping blocks covers the same scale line 4 at the same time, it is convenient for multiple clamping blocks 3 to position and clamp bolt bodies of the same size.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
