Problems solved by technology

Some indexable and indexable fixtures are positioned by stepping motors, which is not only costly, but also cannot be used for motion and rotation
Some indexing and indexing fixtures are rotated by a rotary hydraulic motor and positioned by positioning pins. For 90-degree indexing, 4 limit hydraulic devices are required, and for 45-degree indexing, 8 limit hydraulic indexing devices are required. , complex structure, high cost
Some indexable and indexable fixtures use manual indexing, which cannot be used on moving parts, and the efficiency is low

Abstract

The invention discloses a hydraulic indexing clamping device capable of quickly replacing workpieces. The device is characterized by comprising a fixed base, a rotating component, a positioning component, a pressing component and a hydraulic rotating joint. The rotating component comprises a revolving shaft, a swing hydraulic cylinder and an overrunning clutch. The swing hydraulic cylinder drives the revolving shaft to rotate in one direction through the overrunning clutch. The positioning component is used for preventing the rotating shaft from rotating in the machining operation. The pressing component comprises a second hydraulic cylinder, a thrust ball bearing and a pressing disc. The second hydraulic cylinder is fixed on an upper base plate of the fixed base component by a cylinder body thereof; and a pressing hydraulic rod of the second hydraulic cylinder downwards extends outside the upper base plate. The pressing disc is arranged on the pressing hydraulic rod of the second hydraulic cylinder in a coaxial rotating manner through the thrust ball bearing. The pressing hydraulic rod of the second hydraulic cylinder and the revolving shaft of the rotating component are coaxially arranged. The fixed base is fixed at the right end of a machine tool main shaft mounting base by a disc connecting part thereof; and the hydraulic rotating joint is arranged at the left end of the machine tool main shaft mounting base.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a hydraulic indexing clamping device capable of rapidly replacing workpieces. Background technique [0002] At present, in the processing of mechanical parts, it is often encountered that various parts such as valve bodies, three-way or four-way pipe joints need multi-faceted transposition and multi-process processing. Positioning and clamping greatly reduces the processing efficiency, and the position requirements of the processing parts on each surface cannot be guaranteed due to the two positionings, thereby reducing the qualified rate of the product. Some fixtures such as hydraulic clamping or pneumatic clamping used on some highly automated mechanical processing machine tools, when processing different surfaces of the same workpiece, only need to index and index the workpiece during the processing. Some indexable and indexable fixtures ar...
