Abstract

The invention relates to a hydraulic and pneumatic combined clamping device for machining a shell, which comprises a base and four pairs of hydraulic cylinders, wherein the base has a reversed T-shaped structure and is formed by a bottom transverse base plate and a strut arranged on the base plate; the four pairs of hydraulic cylinders are arranged on the left and right two sides of the strut symmetrically two by two; and the four pair of hydraulic cylinders on the left and right two sides of the strut and an upper limiting plate and a lower limiting plate form four clamping areas for clamping a workpiece. In the invention, the vertical tower structure which is symmetric about an X-axis and a Y-axis along the Z axis of the base of the hydraulic and pneumatic combined clamping device for machining the shell is formed, the loading and clamping are stable and reliable, a hydraulic pressure self-locking function is realized, the stress on the workpiece is uniform, and the machining reliability is ensured completely; and the connection of an air path and an air path is reliable, gentle and free from leakage, the positioning precision is high, the synchronous automatic machining of multiple horizontal processing centers can be realized, the interchangeability is high, the workpiece is mounted and clamped in a stream manner, the production efficiency is improved, and the quality of the product is guaranteed.

Description

technical field [0001] The invention relates to a clamping device, in particular to a hydraulic-gas combined clamping device for shell processing. Background technique [0002] At present, in the field of mechanical processing in my country, the multi-face machining of shell workpieces should be clamped by lathes, milling machines, and drilling machines with multiple technological equipment, and the whole process of processing is a single piece of multi-person operation. Conversion, resulting in the dimensional accuracy of the shell is difficult to guarantee the quality of parts. [0003] In view of this, in view of the above problems, a hydraulic-pneumatic combined clamping device for shell processing with reasonable design and effectively improving the above defects is proposed. Contents of the invention [0004] The purpose of the present invention is to provide a hydraulic-gas combined clamping device for shell processing, which can effectively solve the problems of la...
