AI Technical Summary
The traditional shaft detection method has poor limiting properties on the shaft, and cannot maintain the stability of the shaft when it is pressed. It is only suitable for down-pressing detection of the middle end after both ends are supported, and cannot detect the individual end, which lacks practicality.
An adjustable fixture for shaft quality inspection is designed, including a workbench and fixture mechanism. The fixture mechanism achieves stable limit and clamping of the shaft through the combination of a V-shaped load seat, a V-shaped clamp seat, a support frame and an extrusion screw, ensuring the stability of the shaft during the inspection process, and independently clamping and testing the two ends of the shaft.
Through this adjustable fixture, the limiting effect and stability of the shaft during the detection process is ensured, independent detection of both ends of the shaft is achieved, and the practicality and accuracy of the detection are improved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamps, in particular to an adjustable clamp for shaft rod quality detection. Background Art
[0002] The purpose of hardness testing after the shaft is produced and processed is to ensure product quality, evaluate its mechanical properties, and ensure safe use. As one of the important indicators for measuring the mechanical properties of materials, hardness directly affects the key properties of the shaft, such as wear resistance, compressive strength, and fatigue resistance. Through hardness testing, we can promptly discover whether there are quality problems with the shaft, such as improper material selection, imperfect heat treatment process, etc., so as to make timely production adjustments to ensure that the product meets the predetermined quality standards. In addition, hardness testing can also provide customers with shaft products that meet their personalized needs and enhance customer satisfaction. Therefore, hardness testing is an indispensable part of shaft production and processing, and is of great significance for ensuring product quality and safe use.
[0003] Traditionally, when inspecting the shaft rod, the shaft rod is simply placed on a V-shaped support. There are two V-shaped seats, one supporting the bottom two ends of the shaft rod respectively. There is an oil cylinder located above the middle position of the shaft rod. The descent of the oil cylinder presses down the middle position of the shaft rod through a pressure piece. Although this method is simple to operate, it has relatively poor positioning properties for the shaft rod, and the stability of the shaft rod when being pressed cannot be maintained during the pressing process. Secondly, it is only suitable for pressing down on the middle end after both ends are supported, and cannot be used to detect a single end, so it is not very practical. Utility Model Content
