A camshaft end face detection device and method

Abstract

The invention provides an end surface total runout detecting device, and provides a cam shaft end surface detecting device which comprises a bottom plate; a bearing pedestal, a positioning block and agroup of V-shaped blocks for holding a cam shaft are fixed on the bottom plate; an angular contact ball bearing is mounted on the bearing pedestal; a core shaft is mounted in an inner hole of the angular contact ball bearing; a bearing sleeve sleeves the angular contact ball bearing; the outer wall of the bearing sleeve is connected with a differential meter fixing rod; a differential meter is fixed to the tail end of the differential meter fixing rod; and an inner ring adjusting gasket and an outer ring adjusting gasket are arranged in the angular contact ball bearing. The invention furtherprovides a detecting method which comprises the following steps of preadjusting, checking and detecting. The detecting device has no requirement on a detecting environment, can be directly mounted ina cam shaft storage unit at the tail end of a production line to be used, and can directly detect a product; after the bearing sleeve is swung by a hand, and a workpiece is rotated, the reading on thedifferential meter is read; and the structure is simple, the use is convenient, and the result is accurate and reliable.

Description

technical field [0001] The invention relates to a camshaft end face detection device and method, belonging to the technical field of camshaft detection. Background technique [0002] With the development of technology, customers have higher and higher requirements for engine performance. The precision requirements and functions assigned to the camshaft in the engine are also increasing. Among them is a requirement of "full jump of the spindle end face". During the manufacturing process, "on-line inspection" is a difficult problem in the same industry. Usually, it is checked with special testing equipment or a three-coordinate detector. These two types of equipment have very strict environmental requirements and are not suitable for on-site inspection at any time. And checking once is a waste of time. Production quality cannot be effectively controlled in real time, and production efficiency cannot be improved. Therefore, using special equipment or a three-coordinate det...

AI Technical Summary

Problems solved by technology

These two types of equipment have very strict requirements on the environment and are not suitable for on-site inspection at any time

And check it once, it's a waste of time

Production quality cannot be effectively controlled in real time, and production efficiency cannot be improved

Therefore, using special equipment or a three-coordinate detector to check cannot meet the requirements of production and delivery at all.
