Tool for drilling and tapping inner side transverse hole

Abstract

The invention discloses a tool for drilling and tapping an inner side transverse hole. The tool comprises an electric hand drill with a handle cross rod removed, two side rods, a connecting block, a screw rod, a limiting mechanism and a handle, the two side rods are oppositely and fixedly mounted on the peripheral surface of the electric hand drill and extend out of the peripheral surface of the electric hand drill, and two ends of the connecting block are fixed on the parts, extending out of the electric hand drill, of the two side rods; and a bolt hole is formed in the center of the connecting block, the center of the bolt hole and the center of a drill bit of the electric hand drill are located on the same horizontal line, one end of the screw rod is provided with threads matched with the bolt hole and screwed in the bolt hole, the other end of the screw rod is connected with the limiting mechanism, and the handle is fixed to the screw rod. The tool for drilling and tapping the inner side transverse hole is easy to manufacture, accurate in drilling, convenient and fast to operate, firm in positioning, safe and reliable, the labor intensity is reduced, and meanwhile the drilling efficiency of the tool for drilling and tapping the inner side transverse hole is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a tool for drilling and tapping inner transverse holes. Background technique [0002] As a common mechanical process in mechanical processing, drilling is often encountered in production. According to the usual method of processing the inner transverse hole in the factory, it is processed with an elbow on the boring machine; or on the machine tool after opening the process hole on the side of the frame. For processing; or use a hand electric drill horizontally for processing. If you use a hand electric drill to directly drill the inner lateral hole, you need the hand drill to work in a horizontal state, and the manpower is applied perpendicular to the drilling direction, which will cause the drilling position to shift and affect the size and tolerance, quality and processing accuracy of the hole. Simultaneously, in the process of drilling and tapping...

AI Technical Summary

Problems solved by technology

If you use a hand electric drill to directly drill the inner lateral hole, the hand electric drill needs to work in a horizontal state, and the manpower is applied perpendicular to the drilling direction, which will cause the drilling position to shift and affect the size and tolerance, quality and processing accuracy of the hole.

At the same time, in the process of drilling and tapping transverse holes, due to the fact that the force is not in the same axis as the center of the hole, it is easy to cause safety accidents

Can not achieve the effect of accurate positioning, stable quality, safe and efficient processing
