Description

Technical Field

[0001] The utility model relates to the technical field of ceramic ball processing and detection, in particular to a torsion spring comparator used for ceramic ball detection. Background Art

[0002] When testing the performance of ceramic balls, it is necessary to understand the hardness and geometric characteristics of the balls, but existing testing instruments still have certain defects when used;

[0003] During use, understanding the hardness and geometric properties of existing spheres often requires multiple steps. The overall operation process is cumbersome and prone to operational errors or omissions, which reduces detection efficiency and makes it difficult to achieve very high detection accuracy, especially for small defects or fine dimensional measurements, thus affecting product quality.

[0004] In order to overcome the above-mentioned defects, prior art 1 (application number 201721266602.7, Chinese patent application date 2017-09-28) is a groove depth measuring device for a dry gas seal end face friction pair, a torsion spring comparator is fixed through a mounting hole on a bracket, a bolt passes through the end of the bracket to compress the torsion spring comparator, the torsion spring comparator is provided with a dial and a measuring rod, the dial is provided with a pointer, the end of the measuring rod contacts the measured position of the dry gas seal end face friction pair, the torsion spring comparator uses a torsion spring wire whose axial elongation is linearly related to the rotation angle as the main amplification element, and converts the linear displacement of the measuring rod into the angular displacement of the pointer. During measurement, the measuring rod moves from a high point to a low point along the sealing groove of the measured position, pushing the lever to swing. At this time, the internal torsion spring sheet will be stretched or shortened, causing the torsion spring sheet to rotate and the pointer to deflect. The groove depth of the sealing groove can be obtained by reading the pointer reading;

[0005] Although the existing technology can perform accurate measurements through a torsion spring comparator, during operation, the working surface of the torsion spring comparator is not convenient for limiting the ceramic ball, so a clamping structure needs to be set for limiting, which increases the overall installation and design costs, thereby increasing the subsequent maintenance costs. In addition, the torsion spring comparator needs to be placed on a desktop. If the desktop or the ground is uneven, the torsion spring comparator on the desktop is prone to tilt, resulting in deviations in the measurement results, affecting the accuracy and consistency of the test.

[0006] In response to the above problems, it is urgent to carry out innovative design based on the original torsion spring comparator used for ceramic ball detection. Therefore, we proposed a torsion spring comparator for ceramic ball detection that can well solve the above problems. Utility Model Content
