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

Embodiment 1）

[0070] See figure 1 with figure 2 , The rapid indexing hydraulic indexing clamping device of the present invention includes a fixed base 1 , an upper cover assembly 2 , a lower cover assembly 3 , a rotating assembly 4 , a positioning assembly 5 , a pressing assembly 6 and a hydraulic rotary joint 7 .

[0071] See Figure 1 to Figure 4 , The fixed seat 1 is a steel integral piece. The fixed seat 1 includes a disc connecting portion 1-1, an upper seat plate 1-2, a middle seat plate 1-3 and a lower seat plate 1-4. The axis of the disc connection part 1-1 is arranged horizontally along the left and right directions. The disk connecting portion 1-1 is provided with a positioning taper hole 1-1-1 opening to the left. A first oil pipe hole 1-1-2 runs through the left and right sides of the disk connecting portion 1-1. A dust-proof rubber ring 1-5 is arranged in the first oil pipe hole 1-1-2. The upper seat plate 1-2 is horizontally arranged on the upper right side of the disk ...

Abstract

The invention discloses a fast-transposition hydraulic indexing clamping device. The fast-transposition hydraulic indexing clamping device is characterized by comprising a fixing seat, a rotation assembly, a positioning assembly and a hydraulic rotation connector; the rotation assembly comprises a rotation shaft, a swing hydraulic cylinder, an overrunning coupler and a rotation-prevention assembly; the swing hydraulic cylinder drives the rotation shaft to rotate in one direction through the overrunning coupler; the positioning assembly comprises a first hydraulic cylinder which is fixedly arranged on a middle seat plate of a fixing seat assembly; a positioning hydraulic rod of the first hydraulic cylinder can stretch out of the middle seat plate upwards and be inserted into a seat positioning hole corresponding to an installation seat part of the rotation shaft of the rotation assembly; the rotation-prevention assembly is arranged on the upper side of the lower seat plate of the fixing seat and used for multiple times of continuous rotation of the overrunning coupler; the fixing seat is fixedly arranged at the right end of a machine tool spindle installation seat through a disc connecting part of the fixing seat, the hydraulic rotation connector is arranged at the left end of the machine tool spindle installation seat, and all corresponding oil outlets of the hydraulic rotation connector are communicated with the swing hydraulic cylinder and the first hydraulic cylinder through corresponding pipelines.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a hydraulic indexing and clamping device for rapid indexing. 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 are positioned by s...
