Abstract

The present invention relates to a fixture processing method, which comprises: 1) processing each component of the fixture to not higher than a first predetermined precision, and assembling the fixture; 2) setting up an electric discharge machine, and assembling the first machining electrode to the machining center In the electrode mounting part on the arm, and the base is fixed to the electric discharge machine, wherein the first machining electrode is configured to be suitable for machining the inner wall of the base; 3) The first machining electrode is used to machine the inner wall of the base to Not less than the second predetermined precision; 4) Raise the processing arm, disassemble the first processing electrode, and install the second processing electrode into the electrode mounting part on the processing arm; 5) Install the assembled jig to the base 6) Fitting the calibration piece into the jaws of the fixture and clamping; 7) Submerging at least a portion of the base and the fixture into the working fluid; 8) Using the second machining electrode to machine the jaws of the fixture to Not lower than the third predetermined precision.

Description

technical field [0001] The present invention relates to the field of manufacturing of assembly tools in general, and more particularly to a machining method for manufacturing jigs. Background technique [0002] Pneumatic grippers are generally known to operate with a gas such as air and are widely used in the field of automated assembly, handling and machining. Compared with hydraulic clamps or mechanical clamps, pneumatic clamps have the advantages of low cost, less pollution during operation, and easy operation. [0003] However, the manufacturing precision and tolerance of the pneumatic clamp are generally relatively large, which leads to a tolerance of about 0.12-0.18mm between the centerline of the workpiece and the centerline of the pneumatic clamp when the pneumatic clamp clamps the workpiece. This tolerance comes from several sources: [0004] 1) The dimensional tolerance of the workpiece itself is usually 0.002mm; [0005] 2) The tolerance generated to ensure the...
