Description

Clamping tool for drilling of sliding block

Technical Field

The invention relates to the technical field of auxiliary tools for sliding block drilling, in particular to a clamping tool for sliding block drilling.

Background

In the existing automobile mold industry, a sliding block is an important component on a mold, and the sliding block is mainly used in the automobile mold production process with the side direction processing requirement, such as the processes of side punching, side trimming, side shaping and the like.

The machining process of the sliding block mainly comprises two steps: firstly, a slide guide surface, a mounting surface, a limiting surface and the like of the slide block are processed on a slide block casting by using numerical control processing equipment. And then, drilling on the mounting surface of the sliding block by manually matching with a drilling mode of a drilling machine, and completing the drilling work of the insert mounting hole. Because the mounting surface of the sliding block is provided with the insert mounting hole in a drilling mode of a manual operation drilling machine, the lateral drilling precision of the manual operation drilling machine is certainly lower than that of the vertical drilling of the manual operation drilling machine, and therefore the existing processing mode of the insert mounting hole on the sliding block is mainly vertical drilling.

However, the limiting surface on the slider is often located on the opposite surface of the mounting surface of the slider, i.e., the slider adopts a vertical drilling hole, the upper surface of the slider is the mounting surface, and the lower surface of the slider is the limiting surface. Meanwhile, one side of the limiting surface is a guide sliding surface which is perpendicular to the mounting surface and the limiting surface, and the other side of the limiting surface is an inclined surface which forms an included angle with the limiting surface. Therefore, when the installation surface of the sliding block is drilled, the sliding block may have unstable gravity center, and the adjusting cushion block is required to be adopted to support the inclined surface, so that the sliding block is leveled. Meanwhile, the leveller is required to check the levelness of the drilling surface, namely the mounting surface, and adjust the cushion block to keep the mounting surface horizontal, which results in long time and low efficiency for workers to adjust the levelness of the mounting surface.
