Improved arc-shaped drilling device

Abstract

The invention discloses an improved arc-shaped drilling device. The device comprises a lifting supporting column body, a supporting frame body and a drilling machine body, wherein the supporting framebody and the drilling machine body are movably installed on the lifting supporting column body; a first rotating motor is fixedly installed in the end surface of the top of the supporting column body, an output shaft of the first rotating motor extends out of the end surface of the lifting supporting column body, and a fixed cross rod is fixedly installed on the end surfaces of the left side andthe right side of the output shaft; and fixed vertical rods are symmetrically arranged on the left side and the right side of the fixed cross rod, the fixed vertical rods are fixedly connected to thelower end surface of the fixed cross rod and the upper end surface of the support frame body, a dovetail groove is formed in the lower side end surface of the supporting frame body on the left side ofthe lifting supporting column body, and a sliding rail which extends leftwards and rightwards is arranged on the inner top wall of the dovetail groove. According to the improved arc-shaped drilling device, holes with different radian and distributed in an arc shape can be formed in the workpiece, the radian is convenient to adjust, the punching force is high, and the punching speed is high.

Description

technical field [0001] The invention relates to the field of drilling machinery, in particular to an improved arc drilling equipment. Background technique [0002] The workpiece generally needs to be provided with several slots. Due to the different requirements of the workpiece, the position distribution of the slots on the workpiece is also different. There are linear distribution, cross distribution or arc distribution, etc. At present, the arc distribution on the workpiece The structural design of the slotted equipment is complicated and difficult, which increases the difficulty of manual operation, and the operation steps are cumbersome, which is not conducive to quickly punching the workpiece into arc-shaped slots. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved arc-shaped drilling device, which can solve the above-mentioned problems in the prior art. [0004] The present invention is achieved ...
