It needs to be processed twice on a turning or drilling machine, and the two processings bring about two positionings. In this way, the coaxiality of the center holes processed on both ends is poor, which directly affects the processing accuracy of the cylindrical rollers, and the production efficiency is not high.

Embodiment Construction
[0019] The present invention is a method for drilling the center holes on both ends of cylindrical rollers by using a depth control device. The method can not only drill the center holes on both ends of cylindrical rollers simultaneously, but also ensure the same working speed and working depth. The central holes on both ends of the cylindrical rollers have higher coaxiality, which simplifies the processing procedure and improves the processing accuracy and production efficiency.
[0020] The present invention uses a depth control device and a controller, and the depth control device includes a base 1, a workpiece clamping device 2, a left punching power device, a right punching power device, a left lateral drive device, a right lateral drive device, a left measurement device and the right measuring device, the controller controls the working speed, working depth and rotation speed of the depth control device and meets the various working requirements of the depth control devic...

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 ...
