Embodiment Construction

[0015] The probe should be calibrated before invoking the camshaft online measurement process. The calibration is divided into two steps. The first step is to use the tool setting instrument to adjust the offset between the center of the ruby ​​measuring ball on the probe and the axis of rotation of the probe within 0.005mm. The second step is to calibrate the probe using a standard ring gauge. Calibrate the probe once a week with a standard ring gauge. If the calibration fails, use a tool setting instrument to readjust the probe so that the offset between the center of the ruby ​​measuring ball on the probe and the axis of rotation of the probe is controlled within 0.005mm. Inside.

[0016] The first step, measurement and positioning during clamping: carry out axial and circumferential measurement and positioning of the camshaft blank; the camshaft online measurement process is to directly measure and position the camshaft blank in the axial and circumferential directions, w...

Abstract

The invention relates to the technical field of camshafts, in particular to an online camshaft measuring and machining process which comprises the following steps: 1. measuring and positioning during installing and clamping: carrying out axial and circumferential measuring and positioning on a blank camshaft; 2. improving precision by measuring abrasion of a compensation cutter: automatically measuring the abrasion of the compensation cutter through rough turning, half-fine turning and measuring programs so as to ensure machining precision; and 3. improving precision by measuring practical positions of compensation holes: measuring the practical position coordinates of the compensation holes so as to improve the displacement of the holes. The online camshaft measuring and machining process is simple to operate, carries out positioning by a probe during installing and clamping, automatically measures the abrasion of the compensation cutter through rough turning, half-fine turning and measuring programs so as to ensure machining precision, measures the practical positions of the compensation holes so as to improve the precision, so that the operation program not only can improve machining efficiency, but also can greatly improve the quality of produced products, and avoid generation of waste products after being off-line.

Description

technical field [0001] The invention relates to an on-line measurement processing technology, in particular to an on-line measurement processing technology of a camshaft. Background technique [0002] The camshaft is a key part of the internal combustion engine. Traditional machining requires special tooling and off-line measurement to ensure its machining accuracy. If the cam is to be turned and milled for the first time, it is necessary to know the position of each cam during each clamping process. The conventional process to solve this problem is to make special equipment to locate the camshaft, first process the positioning pin hole and then process the cam profile. This processing technology has very high requirements on the quality of the blank and the quality of the equipment. The accuracy of the positioning equipment is not enough to completely process the cam profile, so not only the processing efficiency is low, but also the waste product may be known only after of...
