Embodiment Construction

[0014] An embodiment of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 2 As shown, the specific number of probes 1 is determined according to the actual situation, and must be one row or several parallel rows, and the more the number of rows, the higher the measurement accuracy. The length of each row depends on the width of the metal wear position. It is necessary to ensure that a part of each row of probes is located in the groove formed after the metal wear, while the other part is located on both sides of the wear groove.

[0016] Each probe is made of a special material, which has its own resistance, and the resistance value changes linearly with the change of the length under the condition of constant cross-sectional area. These probes are all fixed in corresponding holes on the metal plate 3, and each probe end is connected with a wire. And the spring 2 can ensure that each probe can return...

Abstract

The invention discloses a metal abrasion loss measurement method and an implementation device, and relates to the online monitoring technology of metal abrasion loss, and solves the problem of abrasion online monitoring of some key components in existing engineering mechanical equipment. The technical scheme is that: after a worker zeros the device, the device is slightly pressed downwards at a measurement position with two hands until all probes make contact with the surface of meta, each branch is externally connected with a voltmeter, the voltage of each branch is measured by the corresponding voltmeter, the measured data are uploaded to a processor, and the processor processes the data and then displays the image on a display, wherein the processor converts each voltage into a length unit, the value measured at the metal surface can be set to zero, the value measured in the abrasion groove can be set to a negative value, and the difference between the two values is the depth of metal abrasion. The metal abrasion can be detected in a simple and practical manner, the detection precision is high, and the application range is wide.

Description

technical field [0001] The invention relates to a wear measurement device, in particular to a metal wear measurement device. Background technique [0002] With the continuous development of science and technology, people have made great progress in the control of mechanical instruments, vehicles, etc., hoping to achieve real-time control of the operation of the machine. The parts come into contact when the machine is running, and this contact causes the metal to rub, causing the parts to wear. Wear and tear will reduce the accuracy of the machine, generate noise and vibration, etc. For example, due to the size change of the piston ring of the generator due to wear and tear, the opening gap of the piston ring is significantly increased, resulting in insufficient power of the generator and increased fuel consumption. [0003] However, the accurate measurement of metal wear has always been a major problem, plaguing many industries. There are also some traditional methods for...
