Method for drilling center holes in two end faces of cylindrical roller by using depth control device

Abstract

The invention relates to a method for drilling center holes in two end faces of a cylindrical roller by using a depth control device. The depth control device overall comprises a pedestal, a workpiece clamping device, a first motor, a belt, a center drill, a nut base, a drilling shaft, a sliding base, a sliding block, a second motor, a shaft coupler, a bearing pedestal, a ball screw, a screw nut, a guide rail, a linear guide sleeve, a reset spring, a bar hoop, a measuring bar, a rod clamp, a touch rod, a measuring head and a measuring head base. The depth control device accepts effective control of a controller, provides good guarantee for drilling the center holes in the two end faces of the cylindrical roller, and has the characteristics of simple structure, easiness in manufacturing and convenience in use. Through the depth control device, the center holes can be drilled in the two end faces of the cylindrical roller simultaneously, equal work speed and equal work depth can be guaranteed, the center holes in the two end faces of the cylindrical roller have high coaxiality, the processing process is simplified, and the processing precision and the production efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of roller center hole processing, in particular to a method for drilling center holes on both ends of a cylindrical roller by using a depth control device. Background technique [0002] At present, the traditional method is to locate the supporting journal of the cylindrical roller, and respectively turn or drill the center holes on both ends. It needs to be processed twice on a turning or drilling machine, and the two processings bring about two positionings, so that the coaxiality of the central holes processed on both ends is poor, which directly affects the processing accuracy of the cylindrical roller, and the production efficiency is not high. The invention overcomes the deficiencies in the prior art, and adopts a new automatic control device for the center hole depth of the cylindrical roller double-end drill. Contents of the invention [0003] In view of the above situation, the present invention ...
