High-precision automatic alignment type multi-position workpiece pinching device

Abstract

The invention relates to a high-precision automatic alignment type multi-position workpiece pinching device, which belongs to the field of pinching devices. The high-precision automatic alignment type multi-position workpiece pinching device comprises a chuck mechanism, a telescoping mechanism, an elevating mechanism, an anti-reverse guide mechanism and a base mechanism, wherein the elevating mechanism and the anti-reverse guide mechanism are arranged on both sides of a guide post in the center, the telescoping mechanism is arranged on the upper end surface of a cross beam of an upper T-shaped frame, a telescoping connecting rod of the chuck mechanism is connected with an inner guide post rod of the telescoping mechanism, and the telescoping mechanism is used for controlling the chuck mechanism to stretch, open and close. According to the high-precision automatic alignment type multi-position workpiece pinching device, the alignment requirement of a workpiece can be automatically realized, and the multifunctional requirements of transposition, clamping, retraction and sending, positioning, high-precision mold closing and the like in multiple positions can be satisfied. When the high-precision automatic alignment type multi-position workpiece pinching device is moved, the ranges of elevation, opening and closing, positioning and stretching are large, and the pinching device can be conveniently adjusted, operated and controlled.

Description

technical field [0001] The invention belongs to a clamping device, in particular to a high-precision automatic centering type multi-station workpiece clamping device. technical background [0002] The workpiece transposition clamping device is an indispensable device in the design structure of the multi-station hydraulic machine body. Hydraulic machines generally guarantee the shifting, positioning, centering, and high-precision mold clamping of a station, which is easier to achieve. However, it is very difficult to realize the requirements of shifting, positioning, centering, and high-precision mold clamping of any station on a multi-station hydraulic press. If the requirements such as displacement, positioning, centering, and high-precision mold clamping cannot be realized, the function of multi-station molding and manufacturing cannot be realized.

Problems solved by technology

However, it is very difficult to realize the requirements of shifting, positioning, centering, and high-precision mold clamping of any station on a multi-station hydraulic press.

If the requirements of shifting, positioning, centering, and high-precision mold clamping cannot be realized, the function of multi-station molding and manufacturing cannot be realized.

At present, the hydraulic press adopts an external auxiliary device, mainly using an auxiliary mobile pinch device, which has low precision and low efficiency, especially for thermal molding with poor effect and low yield

Moreover, the centering accuracy of different stations is poor, so it is difficult to achieve high-precision mold clamping requirements

The current equipment can only realize one or two specific functions, and can fully realize the requirements of shifting, positioning, centering, high-precision mold clamping, etc. and integrate them into one device. At present, there is no suitable device to realize multiple functions. Requirements for station displacement, positioning, centering, high-precision mold clamping, etc.
