Robot-dedicated mechanical fixture

Abstract

The embodiment of the invention discloses a robot-dedicated mechanical fixture. An end rotary shaft of a robot is utilized as a power source, the power of the end shaft of the robot is transmitted to a first stepped shaft by connecting the first stepped shaft with an end moving shaft of the robot, moreover, the power is transmitted onto a cam via a half-tooth bevel gear, second stepped shafts and third stepped shafts, the cam then alternately rotates by 180 degrees to open and close grabbing plates, and thereby the requirement of the action of clamping a workpiece is met. The robot-dedicated mechanical fixture solves the technical problems of complex structure, difficulty in mounting and instability in use existing in industrial robot fixtures with an additional power source.

Description

technical field [0001] The invention relates to the field of automatic fixtures, in particular to a special mechanical fixture for robots. Background technique [0002] The types of fixtures for industrial robots can be divided into: [0003] 1. Universal fixture. Such as machine vise, chuck, suction cup, dividing head and rotary table, etc., have great versatility and can better adapt to the transformation of processing procedures and processing objects. The structure has been finalized, and the size and specifications have been series Most of the manipulator accessories have become a standard accessory for machine tools. [0004] 2. Special fixture. It is specially designed and manufactured for the clamping needs of a certain product part in a certain process. It serves a specific target and is highly targeted. Generally, it is designed by the product manufacturer itself. Commonly used are lathe fixtures, milling machine fixtures, drilling molds, boring molds and accom...
