The camshaft detection tool has the advantages of high detection accuracy and high detection efficiency.

Description

A camshaft detection tool

technical field

The utility model relates to the technical field of camshaft manufacture, in particular to a camshaft detection tool.

Background technique

Great Wall EG01 intake camshaft signal plate assembly requires high axial dimensions, and its quality is mainly guaranteed by the axial dimension of the rear end face of the intake camshaft. At present, due to the lack of suitable testing tools, daily inspection is very cumbersome and inaccurate , the effect is not ideal.

Utility model content

In view of the above defects, the utility model provides a camshaft detection tool, which improves the detection accuracy and improves the detection efficiency.

In order to achieve the above object, the technical solution of the utility model is:

A camshaft detection tool, comprising a bottom plate, a top plate, two connecting rods connecting the bottom plate and the top plate, a live center is set in the middle of the top plate, a dead center is set in the middle of the bottom plate, a measuring frame is set on one of the connecting rods, the An L-shaped probe is hinged in front of the measuring frame, a coiled spring is arranged on the hinge shaft, a dial indicator is arranged on the measuring frame, and the measuring head of the dial indicator is offset against the L-shaped probe.

Further, the live top includes a top sleeve, which is fixedly arranged on the top plate, and the end of the top sleeve is provided with a cover plate, and the top sleeve is provided with a push rod that can move up and down in the top sleeve, and the middle part of the push rod is provided with A shaft shoulder, a compression spring is set between the shaft shoulder and the cover plate, and is sleeved on the ejector rod; the ejector rod protrudes from the cover plate, a baffle plate is arranged at the end of the ejector rod, a wrench is arranged between the baffle plate and the cover plate, and the cover plate The end is hinged with a pressure rod, and the pressure rod is fixedly connected with the wrench.

As an improvement to the above technology, the upper part of the top sleeve is provided with an external shaft shoulder, the lower part is provided with external threads, the top plate is provided with a mounting hole, and the top sleeve is installed in the mounting hole and fixed and compressed by a nut.

In the camshaft detection tooling of the present utility model, a measuring frame is installed on the connecting rod, a standard sample is first placed on the detection tooling, and the position of the shaft end face of the standard sample is measured by the measuring frame, that is, the size of the standard sample is determined, and then , fix the measuring frame on the connecting rod, place the workpiece to be measured, the position change of the end surface of the workpiece axis to be measured is the change of the axial dimension, the L-shaped probe is offset against the end surface of the workpiece axis to be measured, and the L-shaped probe The other end is offset against the measuring head of the dial indicator, so that the change of the axial dimension is converted into a change of the radial dimension. The change of the axial dimension of the workpiece to be measured and the standard sample is passed through the L-shaped probe and the dial indicator. It is converted into the change of the scale number of the dial indicator, so as to accurately reflect the axial dimension of the workpiece to be measured. The detection accuracy is high and the detection efficiency is high. This tool can not only detect the Great Wall intake camshaft, but also can be extended to the detection of other similar camshafts.
