Drilling machine for special-shaped workpiece

Abstract

The invention relates to the technical field of drilling clamps, in particular to a drilling machine for a special-shaped workpiece. The drilling machine comprises a supporting mechanism, a clamping mechanism and a movable drilling mechanism, wherein the supporting mechanism comprises a supporting table and supporting columns, supporting legs are fixedly connected to the four end corners of the bottom face of the supporting table, a first rectangular groove is formed in the middle of the top face of the supporting table, a second rectangular groove is formed in the middle of one short side wall of the supporting table, and sliding grooves are formed in the top face of the supporting table by facing four diagonal lines with the middle of the supporting table serving as the center point. According to the drilling machine for the special-shaped workpiece, a first two-way lead screw and a second two-way lead screw are rotationally connected into the first rectangular groove and the second rectangular groove, a first connecting lug and a second connecting lug drive the clamp to clamp the special-shaped workpiece by rotating the first two-way lead screw and the second two-way lead screw, so that the surface of the special-shaped workpiece cannot be damaged, the whole fixing process is more time-saving and labor-saving, and the fixing efficiency of the special-shaped workpiece is greatly improved.

Description

technical field [0001] The invention relates to the technical field of drilling fixtures, in particular to a drilling machine for special-shaped workpieces. Background technique [0002] Most of the existing processed products can be divided into two categories: standard parts and non-standard parts. Standard parts are the same size, material and specification used under normal circumstances. Such products are usually in large quantities, and non-standard parts are Special-shaped workpieces, that is, the sizes, materials, and specifications used in special cases are different. Such products are usually made according to specific design drawings; [0003] When processing and drilling special-shaped workpieces, because the size and shape of each processed product are different, it is difficult for traditional fixtures to have a good fixing effect on the clamping of special-shaped workpieces, resulting in the processing of special-shaped workpieces.

Problems solved by technology

[0003] When processing and drilling special-shaped workpieces, because the size and shape of each processed product are different, it is difficult for traditional fixtures to have a good fixing effect on the clamping of special-shaped workpieces, resulting in the processing of special-shaped workpieces. The difficulty of holes increases. Traditional processing of special-shaped workpieces generally requires positioning holes on the surface or other positions of the special-shaped workpieces, and then uses fixtures to fix the special-shaped workpieces according to the positions of the positioning holes. However, this method will destroy the special-shaped workpieces. Integrity makes it difficult to meet certain special requirements. Second, this method is more cumbersome to fix, and it is inconvenient to disassemble or clamp special-shaped workpieces, which is not conducive to the processing efficiency of the factory. Therefore, there is an urgent need for a fast and easy-to-fix Special-shaped workpiece drilling device that damages special-shaped workpieces
