Detailed Description

The principles and features of the present invention are described below in conjunction with fig. 1-5, which are provided by way of example only to illustrate the present invention and not to limit the scope of the present invention.

A clamp for processing a central hole of a fastener is disclosed, wherein the clamp 20 comprises an upper fixed block 1, a lower fixed block 2, a mandril 3, a guide rod 16, a spring 17 and a supporting plate 18.

The upper fixed block 1 is arranged above the lower fixed block 2, and the supporting plate 18 is arranged below the upper fixed block 1. The bottom ends of the guide rod 16 and the ejector rod 3 are respectively fixedly connected with the supporting plate 18, and the top end of the guide rod 16 penetrates through the lower fixed block 2 and then is fixedly connected with the upper fixed block 1. In this embodiment, the guide rods 16 are symmetrically distributed and have two total numbers. The springs 17 correspond to the guide rods 16 one to one. The spring 17 is sleeved and connected with the guide rod 16, the top end of the spring 17 is connected with the bottom surface of the lower fixed block 2 in a jacking mode, and the bottom end of the spring 17 is connected with the upper surface of the supporting plate 18 in a jacking mode. The upper fixed block 1 can slide up and down relative to the lower fixed block 2, but under the action of the spring 17, the upper fixed block 1 always has the movement tendency of sliding downwards and being attached to the lower fixed block 2. The upper fixed block 1 and the lower fixed block 2 can be separated by using an air cylinder to press the supporting plate 18 upwards.

The lower fixed block 2 is provided with a lower concave part 5, the upper fixed block 1 is provided with an upper concave part 6, and after the lower fixed block 2 is attached to the upper fixed block 1, the lower concave part 5 and the upper concave part 6 form a fixing groove for placing a fastener 7; the fixing groove matches the shape of the fastening member 7. Specifically, the upper fixed block 1 is composed of an upper body 8 and an upper sleeve 9, a convex part 10 is arranged in the middle of the upper body 8, the upper sleeve 9 is connected in the convex part 10, and a skirt edge 14 of the upper sleeve 9 is attached to the side of the end face of the upper body 8; the upper recess 6 is provided on the upper body 8. The lower fixed block 2 comprises a lower body 11 and a lower sleeve 12, a groove 13 is formed in the middle of the lower body 11, the lower sleeve 12 is connected into the groove 13, and a skirt 14 of the lower sleeve 12 is attached to the end face side of the lower body 11; the lower recess 5 is provided on the lower body 11. When the upper fixed block 1 is jointed with the lower fixed block 2, the fastener 7 is fixed; when the upper fixed block 1 is separated from the lower fixed block 2, the fastener 7 can be removed.
