Abstract

The invention relates to a hydraulically automatic indexing chuck which adopts a hydraulic transmission system for clamping a workpiece (3) and comprises a clamping cylinder (2), an indexing cylinder(4) is arranged on the automatic indexing chuck (1), the indexing cylinder (4) and the clamping cylinder (2) are driven by the same hydraulic transmission system, one surface of the workpiece (3) contacts with a clamping surface of the clamping cylinder (2), and the other opposite surface on the workpiece (3) contacts with an indexing plate (26) of the indexing cylinder (4). The technical scheme realizes clamping, indexing and positioning after indexing for the workpiece by the same hydraulic transmission system, a clamp has small volume, large acting force and convenient operation, and the production efficiency and the processing quality are improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing machine tool equipment, and relates to the structure of the machine tool fixture, and more specifically, the invention relates to a hydraulic automatic indexing chuck. Background technique [0002] At present, most of the fixtures used on machining machine tools with a high degree of automation are hydraulic clamping or pneumatic clamping. However, the workpiece has multiple surfaces in different directions to be processed during the machining process, which requires indexing and indexing of the workpiece during the machining process. [0003] Generally, indexing indexing and positioning after indexing still adopt mechanical methods, and its structure is relatively complicated, the volume is large, and the operation is troublesome. Contents of the invention [0004] The problem to be solved by the present invention is to provide a hydraulic automatic indexing chuck, the purpose of...
