Drilling jig for machining parts of excavator

Abstract

The invention discloses a drilling jig for machining parts of an excavator. The drilling jig comprises a U-shaped clamp main body, wherein the clamp main body comprises two opposite side surfaces and a bottom surface for connecting the two opposite side surfaces; the three surfaces of the clamp main body are respectively provided with a drilling jig sleeve for machining a U-plate, and are respectively jointed with the U-plate; the two opposite side surfaces of the clamp main body are respectively provided with positioning pins for clamping and fixing the U-plate; and the bottom surface of the clamp main body is provided with fixing bolts for fixing the U-plate.

Description

technical field [0001] The invention relates to a mechanical tool, in particular to a drilling mold for processing excavator parts. Background technique [0002] Such as figure 1 As shown, an excavator part, specifically the U-board of the excavator, includes a U-board body, the U-board body includes two sides (2; 3) and a bottom surface 1 connecting the two sides, and the two sides are respectively Correspondingly, there are positioning holes (5; 4) and multiple holes. In the actual processing process, the fixture is generally used to clamp the work and position on the three surfaces of the U-plate successively. The error caused by the three-time positioning processing is relatively large, and the U-plate There are large errors in the empty positions, and batch quality accidents often occur. [0003] This shows that above-mentioned existing U plate processing obviously still has inconvenience and defect in use, and urgently needs to be further improved. In order to solve...

[0002] like figure 1 As shown, an excavator part, specifically the U-board of the excavator, includes a U-board body, the U-board body includes two sides (2; 3) and a bottom surface 1 connecting the two sides, and the two sides are respectively Correspondingly, there are positioning holes (5; 4) and multiple holes. In the actual processing process, the fixture is generally used to clamp the work and position on the three surfaces of the U-plate successively. The error caused by the three-time positioning processing is relatively large, and the U-plate There is a large error in the empty position, and batch quality accidents often occur

[0003] This shows that above-mentioned existing U plate processing obviously still has inconvenience and defect in use, and urgently needs to be further improved

In order to solve the problems existing in U-board processing, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general products do not have a suitable structure to solve the above problems, which is obvious. It is a problem that relevant industry players are eager to solve
