Problems solved by technology

But for a specific single part, in most cases, you can only choose to hold the outer circle tightly or tighten the inner hole.
This clamping method can only process a characteristic surface of the inner hole or outer circle of the workpiece, and the clamping part cannot be processed due to the existence of claws, which has certain application limitations.

Abstract

The invention belongs to the technical field of machining equipment and particularly relates to a chuck capable of conducting flexible clamping. By means of the chuck, inner hole clamping and outer circle clamping of a single part can be achieved on one chuck. The chuck comprises a main shaft, and a rotation table is arranged on the top of the main shaft. The chuck is characterized in that a center cylinder body is arranged in the main shaft, and a center piston connected with a wedge catch system is arranged in the center cylinder body; the wedge catch system is connected with sliding bodiesthrough a guide sliding block; and an inner clamping claw and an outer clamping claw are arranged on each sliding body through a lifting cylinder.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a flexible clamping chuck. Background technique [0002] The existing chuck is to use the claws on the chuck body to move along the radial direction to hold the outer circle of the workpiece or tighten the inner hole of the part. It consists of three parts: the chuck body, the movable jaws and the jaw driving mechanism. But for a specific single part, in most cases, you can only choose to hold the outer circle tightly or tighten the inner hole as a clamping method. This clamping method results in that only one characteristic surface of the inner hole or outer circle of the workpiece can be processed, and the clamping part cannot be processed due to the existence of claws, which has certain application limitations. Contents of the invention [0003] The present invention aims at the above problems and provides a chuck that can realize inner h...
