Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: through the structure, the base can be fixed on the wire cutting workbench, then the U-shaped clamping pins are placed into the clamping grooves at one time and stacked up from top to bottom, the limiting top block is pushed and fixed on the U-shaped clamping pins by the aid of the fastening bolts, the U-shaped clamping pins are positioned in the clamping grooves, accordingly, the hook-shaped processing area of the clamping grooves outside the base is processed by the wire cutting machine, and during processing, only one calibration is needed, hook-shaped processing of the U-shaped clamping pins can be completed, and accordingly efficiency is improved.

Preferably, the cross section of the limiting groove is rectangular, and the limiting top block is of a cuboid structure.

Preferably, the limiting groove is arranged close to the end part of the opening end of the clamping groove.

Furthermore, the depth of the clamping groove is equal to the thickness of ten U-shaped clamping pins. Ten U-shaped clamping pins can be processed at one time, and the processing efficiency is improved.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

FIG. 2 is a schematic structural view of the U-shaped bayonet.

The specific implementation mode is as follows:

the invention will be further explained with reference to the drawings and the detailed description below:

as shown in fig. 1 and 2, a U-shaped bayonet lock hook-shaped processing fixture comprises a base 1 made of 45 steel, wherein a fixing hole is formed in the base 1, so that the base is fixedly connected with a wire cutting workbench by using a bolt, the base 1 is rectangular in the embodiment, one end of the base 1 is concavely provided with a U-shaped clamping groove 2 matched with the U-shaped bayonet lock in shape, the depth of the clamping groove 2 is greater than the thickness of ten U-shaped bayonet locks, in other words, 10U-shaped bayonet locks can be stacked in the clamping groove 2, the open end of the clamping groove 2 extends to the end face of the end part of the base, so that when the U-shaped bayonet lock 5 is placed in the clamping groove, the hook-shaped processing area of the U-shaped bayonet lock 5 is positioned outside the base, the clamping groove 2 comprises a straight-line groove 21 and an arc-section groove, and the length of the straight-arm section 51 of the U-shaped bayonet lock is smaller than that of the straight, when making U-shaped bayonet lock holding in the draw-in groove, the hook-shaped processing position of U-shaped bayonet lock 5 is located outside the base, still be equipped with spacing recess 3 on the base 1, spacing recess 3 is located the draw-in groove and is used for holding the outside of one side that the hooked card arm of U-shaped bayonet lock waited to process, spacing recess 3 and draw-in groove 2 intercommunication, spacing kicking block 4 has been held to spacing recess 3, and the degree of depth of spacing recess 3 and unanimous with the degree of depth of draw-in groove 2, the degree of depth of spacing kicking block 4 is not less than spacing recess, still the level is equipped with the screw on the base that is located the spacing recess outside, threaded connection has fastening bolt 6 in the screw, when U-shaped bayonet lock holding in the draw-in groove, accessible fastening bolt 6 pushes up spacing kicking block 4 and fixes the location. And then, a wire cutting machine is utilized to carry out hook-shaped processing on the hook-shaped area to be processed, so that only the uppermost U-shaped clamping pin needs to be calibrated during processing, and the lower U-shaped clamping pin does not need to be calibrated again.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
