Clamping device of wire feeding machine

Abstract

The invention discloses a clamping device of a wire feeding machine. The clamping device is located on a standard station, standard blocks which are symmetrically distributed are arranged on the standard station, pressing arms are arranged on the standard blocks, and connecting arms are arranged under the pressing arms; an air cylinder is arranged under the standard station; and a first connectingpart and a second connecting part are arranged on the standard station, the second connecting part comprises a first connecting main body, one end of the first connecting main body is provided with acircular sliding countersunk hole, and an elastic part is arranged in the circular sliding countersunk hole. According to the clamping device of the wire feeding machine, pressing and loosening of the pressing arms on a raw material block are controlled through telescoping of the air cylinder, the pressing arms rotate in the mode of leaning on the arc-shaped surface while the pressing arms move upwards under the action of the first connecting part, the second connecting part and the elastic part, then the pressing arms are opened, taking and putting of the raw material block are convenient, traditional manual clamping is replaced, the working efficiency is improved, the requirement of batch production is met, and the labor intensity of working personnel is reduced.

Description

technical field [0001] The invention relates to a clamping device, in particular to a clamping device of a wire feeding machine. Background technique [0002] Wire cutting machine is a kind of wire cutting machine. Wire cutting machine is a high-precision and highly automated processing method. It has been widely used in mold manufacturing, forming tool processing, difficult-to-machine materials and processing of precision and complex parts. Generally, the fixture has strict requirements on the size and shape of the workpiece. In order to ensure the accuracy of the workpiece processing, the fixture is an important mechanism to ensure the machining accuracy. The structure of the fixture determines the difficulty of placing and taking the raw material block during processing, and affects the quality of the raw material block.

Generally, the fixture has strict requirements on the size and shape of the workpiece. In order to ensure the accuracy of the workpiece processing, the fixture is an important mechanism to ensure the machining accuracy. The structure of the fixture determines the difficulty of placing and taking the raw material block during processing, and affects the quality of the raw material block. Appearance, in order to ensure the accuracy of raw material block processing, traditional wire cutting uses screw rod and clamp arm to clamp manually, which is inefficient and cannot meet the needs of mass production. Manual clamping for a long time increases the labor intensity of the staff
