Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the guide sleeve for the hydraulic clamping part comprises a base 1, a hydraulic clamping piece, a first guide sleeve 4, a second guide sleeve 5 and a buffer piece.

In this application, set up the hydraulic pressure holder on base 1 for the centre gripping part, further explanation, the hydraulic pressure holder includes pneumatic cylinder 6 of fixed connection on base 1, fixed connection splint 3 and the fixed plate 2 of fixed connection on base 1 on the 6 piston rods of pneumatic cylinder, so drive splint 3 through pneumatic cylinder 6 and slide, so can carry out the centre gripping to the part fixedly.

In order to fully understand the technical solution for the person skilled in the art, both the first guide sleeve 4 and the second guide sleeve 5 are connected to the hydraulic clamping member;

wherein, first uide bushing 4 fixed connection is in the one end of splint 3, and second uide bushing 5 fixed connection is in the one end of fixed plate 2, and second uide bushing 5 slides and sets up in first uide bushing 4.

To explain further, buffering members are provided in the first guide sleeve 4 and the second guide sleeve 5 for buffering when the hydraulic clamping member clamps the part.

Specifically, the buffer member in the present application includes a tapered rod 8 fixedly connected to the first guide sleeve 4, a sliding plate 7 slidably sleeved on the tapered rod 8, and a buffer spring 9 sleeved on the tapered rod 8.

The second guide sleeve 5 is slidably mounted in the first guide sleeve 4, and the second guide sleeve 5 is fixedly connected with the sliding plate 7, so that the first guide sleeve 4 can slide outside the second guide sleeve 5, in order to increase the buffering effect, a plurality of groups of spring pieces 10 are fixedly connected in the second guide sleeve 5, and the conical rod 8 is in a conical structure, so that when the sliding is continuously performed, the side wall of the conical rod 8 can gradually compress and buffer the spring pieces 10.
