Welding fork trepanning machining jig

Abstract

The invention relates to the field of welding, in particular to a welding fork trepanning machining jig. The jig comprises a fixing table, an abutting mechanism, an alignment mechanism, a shear fork mechanism and a lifting mechanism; an inserting groove is formed in the middle of the fixing table; the working ends of the abutting mechanism are located on the two sides of a welding fork; the alignment mechanism in a working state abuts against a square fork of the welding fork; the working end of the shear fork mechanism is located between the working end of the abutting mechanism and a welding fork circular half-space base, and the shear fork mechanism in the working state is used for clamping the long cylindrical outer wall of the welding fork; and the lifting mechanism is arranged below the shear fork mechanism and controls the shear fork mechanism to move up and down, so that the working end of the shear fork mechanism can abut against the circular half-space base of the welding fork. The technical problem about how to avoid trepanning machining is solved through the mechanisms.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a jig for drilling holes for welding forks. Background technique [0002] In the process of mechanical processing, fixed model tooling is often used when processing workpieces. [0003] Such as Figure 7 The welding fork SS, the base S3 of the welding fork is provided with a circular platform base, the middle is a long circular cylinder S2, and the top of the long cylinder is a square fork S1 square fork The width of the square fork S1 is greater than that of the circular platform base S3. There are U-shaped grooves on the left and right sides of the fork structure, and the uppermost part is a semicircular structure. If the welding fork cannot be effectively avoided during processing The position of the upper opening will eventually lead to unqualified parts. [0004] Based on the above reasons, the present invention applies for a welding fork drilling tool. Contents of t...
