Work fixture for mechanical arm

Abstract

The invention discloses a work fixture for a mechanical arm, and relates to the technical field of industrial instruments. The work fixture comprises a mounting base and a connecting base; the front side face of the connecting base is fixedly connected with a fixture box; and the inner wall of the rear end of the fixture box is fixedly connected with an air cylinder. According to the work fixture, by arranging a spring barrel and side face clamping rods, a workpiece can be limited through three side faces; the workpiece is clamped more firmly by the stability capacity of a triangle; due to the fact that a large number of anti-skid discs can be tightly attached to the surface of the workpiece, the purpose of firm clamping can be better achieved; and by arranging a tensioning spring, a telescopic rod can stretch out and draw back in the spring barrel when being stressed, and accordingly, diameters among three arc-shaped clamping pieces are adjusted; meanwhile, due to the fact that jacking columns can stretch out and draw back in limiting barrels, the work fixture can well adapt to workpieces with different diameters when being used for clamping the workpieces with the different diameters, thereby achieving the purpose that the workpieces with different diameters can be clamped.

Description

technical field [0001] The invention relates to the technical field of industrial equipment, in particular to a fixture for a mechanical arm. Background technique [0002] A robotic arm is a mechanical device that can automatically complete the transfer or operation of objects (such as materials, workpieces, parts or tools, etc.) according to established procedures or requirements, and it can partially replace human manual labor. Higher forms of manipulators can also simulate human arm movements to complete more complex operations. Robotic arms are widely used in the fields of semiconductor manufacturing, industry, medical treatment, military affairs, and space exploration. They all have a common feature, that is, they can accept instructions and accurately locate a certain point in three-dimensional (or two-dimensional) space for operation. . When the mechanical arm is working, the end of the mechanical arm needs to use a special transfer tool to fix the items to be trans...

[0003] At present, after the bearing sleeve is processed, it needs to be transferred. When the bearing sleeve is removed from the lathe, most of the stations are still operated by workers. The bearing sleeve is removed or installed manually. Need to stop, although the work efficiency is higher than that of mechanical fixtures, but occasionally hand slips will occur during transfer, causing the bearing sleeve to fall on the
