Arc drilling device

Abstract

The invention discloses an arc drilling device, comprising a lifting support post, and a support frame and a drilling unit movably mounted on the lifting support post; a first rotary motor is fixedlymounted in the top end of the lifting support post; an output shaft of the first rotary motor is extended out of the end face of the lifting support post; fixing cross rods are fixedly mounted on theleft and right end faces of the output shaft; fixing vertical rods are symmetrically mounted on the left and right of the fixing cross rods; the fixing vertical rods are fixedly connected with the lower end faces of the fixing cross rods and the upper end face of the support frame respectively; a dovetail groove is arranged in the lower end face of the support frame on the left of the lifting support post, and slide rails extended to left and right are fitted to the inner top wall of the dovetail groove. The arc drilling device can drill holes, in arc distribution and having difference radians, in a workpiece, radian adjusting is convenient, drilling force is great, and drilling speed is high.

Description

technical field [0001] The invention relates to the field of drilling machinery, in particular to 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 arc-shaped drilling device, which can solve the above-mentioned problems in the prior art. [0004] The present invention is achieved through the following...
