Description

Technical Field

[0001] The utility model relates to the technical field of material detection, in particular to a hardness detection device for metal materials. Background Art

[0002] Metal materials refer to materials with properties such as luster, ductility, easy conductivity and heat transfer. They are generally divided into ferrous metals and non-ferrous metals. Ferrous metals include iron, chromium, manganese, etc. Among them, steel is the basic structural material, known as the "skeleton of industry." Hardness is one of the important performance indicators of metal materials. Generally, the higher the hardness, the better the wear resistance of the metal material. In order to detect the hardness of metal materials, a metal material hardness detection device is required.

[0003] A test device for detecting the hardness of metal materials is disclosed in a patent document with publication number CN216117174U. However, the test device for detecting the hardness of metal materials uses a threaded handle to move a threaded rod, and the threaded rod drives a fixed plate to move forward and backward, so as to fix metal materials of different specifications. By setting a limit rod and a secondary telescopic rod, the secondary telescopic rod moves along with the fixed plate when the fixed plate moves forward and backward, so as to increase the stability of the fixed plate. However, the shapes of the fixed plate and the rubber plate are both rectangular. When facing an arc-shaped or circular metal material, the contact area between the rubber plate and the arc-shaped or circular metal material is small, resulting in loose fixation of the arc-shaped or circular metal material. During the detection process, the position of the arc-shaped or circular metal material will be offset, thereby affecting the detection accuracy. Therefore, a test device for detecting the hardness of metal materials is needed to solve the above problems. Utility Model Content

Under normal conditions, the rectangular clamping plate 10 is used to clamp and fix the metal material. When it is necessary to clamp and fix the arc-shaped or circular workpiece, the fixing bolt 14 is separated from a fixing socket 12. At this time, the rectangular clamping plate 10 is no longer fixed, so that the rectangular clamping plate 10 can rotate, and then the rectangular clamping plate 10 is rotated to drive the supporting shaft 9 to rotate, so that the rectangular clamping plate 10 rotates 180°. At this time, the arc clamping plate 10 rotates to the clamping position, and the fixing bolt 14 is connected to a fixing socket 12. 12 corresponds to the position, and then the fixing bolt 14 is rotated to connect it with the fixing socket 12, so as to fix the rectangular clamping plate 10.
