Problems solved by technology

[0002] At present, when drilling the center hole for the bar, due to the bending or ellipse of the large-diameter round steel bar, when the center hole is drilled on the ordinary lathe by the conventional method, not only the center drill is easily damaged, but also the center frame vibrates due to the beating of the bar. The accuracy of the machine tool is greatly affected
In the case of many types of shafts and small batches, it is not suitable to purchase a special center hole machine tool

Abstract

The invention discloses a device for drilling a centre hole of bar materials for a lathe. The device comprises a clamping device and a hole drilling device, the clamping device is arranged at the front end of the hole drilling device, and the device is characterized by further comprising a fixed device which is arranged at the back end of the hole drilling device. The device has the advantages that the problems that a centre bit is easy to damage when the center hole is drilled on a common lathe by using a common method through the bar material hole drilling device and lathe accuracy is greatly influenced due to centre frame vibration due to bar material jumping are overcome. The centre hole drilled by the device is good in accuracy, the bar materials do not rotate, and the lathe accuracy is not influenced.

Description

technical field [0001] The invention relates to a drilling machine, in particular to a special device for drilling a center hole with a bar. Background technique [0002] At present, when drilling the center hole for the bar, due to the bending or ellipse of the large-diameter round steel bar, when the center hole is drilled on the ordinary lathe by the conventional method, not only the center drill is easily damaged, but also the center frame vibrates due to the beating of the bar. The accuracy of the machine tool is greatly affected. In the case of many types of shafts and small batches, it is not suitable to purchase a special center hole machine tool. Therefore people aim at this problem, yearn for a kind of simple and convenient in structure, easy-to-use special-purpose drilling rig to solve the bottleneck problem in the production and processing process always. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art. Acc...
