[0027] In the embodiment, the pushing mechanism comprises a pushing cylinder 9, a sliding block mounting base 10, a linear guide rail 30, a guide block 29, a limiting block 11, a pushing claw 12 and a fixed frame 26. The fixed frame 26 is installed at one end of the mounting fixed plate 2, and the end of the fixed frame 26 away from the mounting fixed plate 2 is bent upwards to form a fixed part. The pushing cylinder is installed on the fixed part. The linear guide rail 30 is installed on the surface of the fixed frame 26. The guide block 29 is slidingly arranged on the linear guide rail 30.

[0028] The width of the pushing rod is the same as the width of the material guiding channel. After the pushing claw enters the inside of the material guiding channel, the pushing rod also enters. The feeding port can be blocked by the pushing rod, so that the nut entering the rear of the pushing claw does not affect the return of the pushing claw.

[0029] In the embodiment, the feeding mechanism comprises a feeding bottom plate 5, a top material blocking plate 8, a plurality of feeding blocking blocks 6 and a blocking plate adjusting block 7. The front material channel plate 3 is broken to form a feeding port 23.

[0033] In the embodiment, one end of the mounting fixed seat away from the pushing mechanism is provided with a discharging groove 15 in communication with the material guiding channel.

[0034] In this embodiment, the opposite end faces of the pressing block 14 are inclined to form second flow guide portions, the inside of the upper punch 13 is provided with third flow guide portions on both sides to push the pressing block 14 inward, one end of the pressing block 14 away from the first flow guide portion 21 is provided with a compression spring, and the other end of the compression spring is mounted on the inner wall surface of the sliding groove;

[0035] After the pressing block is pushed inward, the compression spring is compressed, so that after the upper punch moves away from the outside of the pressing block, the springback of the compression spring can push the pressing block outward again, so that the pressing block can be repeatedly closed and opened to achieve the purpose of stamping.

[0036] In this embodiment, the positioning clamp block 19 is provided with a through hole, the positioning groove 20 is provided with a second screw hole opposite to the through hole, a bolt is arranged in the through hole and is screwed with the second screw hole, a rubber ring 31 is mounted on the section of the bolt inside the through hole, and the outer ring of the rubber ring 31 is in abutment with the inner ring surface of the through hole.

[0037] In this embodiment, the positioning clamp block 19 is provided with a through hole, the positioning groove 20 is provided with a second screw hole opposite to the through hole, a bolt is arranged in the through hole and is screwed with the second screw hole, a rubber ring 31 is mounted on the section of the bolt inside the through hole, and the outer ring of the rubber ring 31 is in abutment with the inner ring surface of the through hole.

[0038] In this embodiment, the two sides of the mounting fixed plate 2 are provided with pressing block stop plates 18 for limiting the pressing block, which can limit the distance of the backward movement of the pressing block and avoid the pressing block from being separated from the sliding groove directly.

[0039] In use, the upper punch is mounted on the machine tool, and the feeding bottom plate is generally connected with the vibrating screen, so that the nut can automatically enter the feeding channel and be guided into the guide channel along the feeding channel and the feeding port. At this time, the pushing cylinder can be started to make the piston rod of the pushing cylinder extend, and the movement of the piston rod drives the sliding block mounting seat, the push rod and the pushing claw. The nut can be pushed to the positioning clamp block by the pushing claw, and the first flow guide portion is compressed during the movement of the nut. The positioning clamp block is retreated towards the positioning groove by the compression. When the pushing claw moves to the specified position, the nut enters the limiting groove. After the pushing claw returns, the positioning clamp block is driven by the springback of the tension spring, and the nut is clamped and positioned by the closed positioning clamp block.

[0040] After the above is completed, the machine tool is started, and the upper punch is lowered. The first flow guide portion is compressed by the second flow guide portion during the lowering of the upper punch, so that the pressing block can be automatically closed inward along the sliding groove. The pressing block can stamp the nut inward to deform the ordinary nut hexagonal opposite side shape by lateral pressure, so as to achieve the purpose of thread locking.

[0041] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any change or replacement not through creative labor should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
