The reason why it has become a common method for mechanical property testing is that hardness test can reflect the differences in chemical composition, organizational structure and processing technology of materials.

[0003] For example, a Chinese patent with publication number CN210513979U discloses an efficient metal material hardness testing device, including a base and a main machine, a column guide rod is fixedly installed at the rear of the upper end of the base, a fixed seat is fixedly installed on the upper outer surface of the column guide rod, the upper end of the base is located in front of the column guide rod and is movably connected with a lead screw, the upper end of the lead screw is located above the fixed seat and is fixedly installed with a hand wheel, the outer surface of the lead screw is located between the fixed seat and the base and is movably installed with a slide, the rear end outer surface of the slide is located at the outer surface of the column guide rod and is fixedly connected with a guide sleeve, the lower end outer surface of the guide sleeve is fixedly connected with a telescopic tube, the main machine is located on one side of the slide, and a probe is fixedly connected to the outer surface of one side of the main machine.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the device cannot fix the metal material when in use, the metal material will be displaced due to the vibration of the device during detection, and the device is not convenient for fixed detection of tubular metal materials. In view of this, we propose a metal material hardness detection device. Utility Model Content

[0006] The purpose of the utility model is to provide a metal material hardness detection device to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a metal material hardness detection device, comprising:

[0008] A workbench, wherein a limiting groove is provided on the top surface of the workbench, through grooves connected to the limiting groove are symmetrically provided in the workbench, a U-shaped fixing rod is slidably installed in the through groove, and a sliding plate is slidably installed in the limiting groove;

This process can not only fix rectangular metal materials, but also tubular metal materials, which can avoid the tubular metal material from shaking and make it more stably fixed; when the detector needs to detect tubular metal materials or rectangular metal materials, start the hydraulic cylinder to drive the detector down to a suitable position, turn off the hydraulic cylinder, and then start the detector to detect it; at the same time, the staff can push the support frame by hand to move the support frame back and forth on the workbench, and at the same time, push the hydraulic cylinder by hand to drive the detector to move left and right, ensuring that the detector can fully detect the metal materials on the workbench.
