It is to be understood that other embodiments may be utilized and that mechanical, structural, electrical, and operational changes may be made without departing from the spirit and scope of the present application. The following detailed description is not to be taken in a limiting sense, and the scope of embodiments of the present application is defined only by the claims of the issued patent. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Spatially relative terms, such as "upper," "lower," "left," "right," "lower," "below," "lower," "above," "upper," and the like, may be used herein to facilitate describing one element or feature's relationship to another element or feature as illustrated in the figures.

These terms are only used to distinguish one element from another. For example, the first steering oscillation may be referred to as a second steering oscillation, and similarly, the second steering oscillation may be referred to as a first steering oscillation, without departing from the scope of the various described embodiments.

Please refer to fig. 1, which is a schematic structural diagram of a camshaft quenching detection device for detecting whether a camshaft to be detected is quenched, the detection device includes:

the workpiece support 1 is used for supporting the camshaft test station 2, and the camshaft 3 to be tested is placed in the camshaft test station 2;

the adjustable support is arranged on the workpiece support, and the position of the adjustable support, which corresponds to the camshaft to be tested, can be adjusted up, down, left and right, so that the laser beam of the laser sensor can be aligned to the surface of the camshaft to be tested;

the laser sensor 5 is vertically arranged on the adjustable support 4, emits laser beams to the camshaft 3 to be measured and collects light signals reflected by the camshaft;

and the controller 7 is connected to the laser detector 6, calculates the photosensitive value of the camshaft to be detected and compares the photosensitive value with a preset photosensitive value so as to judge whether the camshaft to be detected is quenched or not.

In this embodiment, when the laser sensor (the type of the laser sensor includes any one of a fixed laser, a liquid laser, a gas laser, or a semiconductor laser, and may also be a laser sensor of model LS-401-C2) operates, a laser emitting diode emits laser pulses to a surface of a camshaft to be measured, the laser pulses are emitted from the surface of the camshaft and then scattered in various directions, and part of the scattered light returns to a laser sensor receiver, and is received by an optical system and then imaged on an avalanche photodiode. An avalanche photodiode is an optical sensor with amplification inside, so that it can detect its weak optical signal and convert it into corresponding electrical signal. The controller receives the electric signal to generate a photosensitive value of the camshaft to be measured, and compares the photosensitive value with a preset photosensitive value (180) so as to judge whether the camshaft to be measured is quenched or not. When the calculated photosensitive value is less than 180, the camshaft to be measured is quenched; when the calculated photosensitive value is larger than 180, the camshaft to be measured is not quenched; meanwhile, the alarm module is connected with the controller and is triggered according to the detection result of the controller, and the alarm module can be any one of optical alarm (indicator light or alarm light), acoustic alarm (horn or sound reminding) or acousto-optic alarm (sound alarm and optical alarm). And when receiving alarm information, the operating personnel can timely process the un-quenched camshaft to avoid entering the next processing flow. For example, the camshaft model can be a 4H camshaft, a 6H camshaft, and can also be a universal camshaft. When the camshaft cams are not quenched, they are prevented from flowing into the engine and assembled into an assembly. And the cam which is not quenched is often installed in the engine, so that the cam is abnormally abraded, the engine is not smooth in air intake and exhaust, and the engine is anchored.

The controller does not relate to a new computer program, and it is also a conventional technical means used by a person skilled in the art to calculate the photosensitive value of the camshaft to be measured and compare the photosensitive value with a preset photosensitive value, for example, the controller can be any one of a PLC programmable logic chip, a microprocessor or a single chip, and the controller can be purchased directly on the market without additional programming development.
