Embodiment Construction

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] A method for detecting the contact pressure of a conductive ring brush wire, the steps are:

[0021] 1) Make a special standard gauge block 2 that is consistent with the key dimensions of the tested conductive ring brush 6;

[0022] 2) Install the special standard gauge block 2 made in step 1) on the fixture tooling 1;

[0023] 3) Use the linear displacement positioning mechanism 4 to position the force-measuring sensor probe 3 to the position where it is in contact with the special standard gauge block 2, which is the working contact position of the brush wire of the conductive ring brush 6 to be tested, and record the position ; After recording the position, separate the force measuring probe 3 from the special standard gauge block 2;

[0024] 4) Remove the special standard gauge block 2, and then install the tested conductive ring brush 6 on the fixture tool ...

Abstract

The invention relates to a conducting ring brush wire contact pressure detection method and device, and belongs to the technical field of force measurement. A special standard gauge block is installed on clamp tools. Force measurement sensor probes are driven through a linear displacement locating mechanism to be in contact with the special standard gauge block, and therefore the location positions of the force measurement sensor probes are determined. The special standard gauge block is taken down, and a detected conducting ring is installed on the clamp tools. The force measurement sensor probes are driven through the linear displacement locating mechanism to reach the previously located positions, the force measurement sensor probes are in contact with a brush wire of the detected conducting ring, and the output value of the force measurement sensor probes is the contact pressure value of the brush wire of the conducting ring.

Description

technical field [0001] The invention relates to a method and a device for detecting the contact pressure of a conductive ring brush wire, belonging to the technical field of force value measurement. Background technique [0002] The conductive ring is the hub of the signal transmission of the rotating body. The pressure of the conductive ring brush wire is one of its important parameters, and its index directly determines the performance of the conductive ring. The measurement of the contact pressure of the conductive ring brush is very important in the production process of the conductive ring. Because, the size of the contact pressure of the conductive ring brush directly determines the contact resistance and determines the life and quality of the conductive ring. Originally, the contact pressure detection of the conductive ring brush was mainly manual operation, and its measurement accuracy mainly depended on the operator's skills and experience to ensure the labor inte...
