Description

Technical Field

[0001] The utility model relates to the technical field of metal hardness detection and fixing devices, in particular to a level adjustment and fixing device for metal hardness detection. Background Art

[0002] Hardness testing is the fastest, most economical and simplest test method for evaluating the mechanical properties of metals. The main purpose of hardness testing is to determine the applicability of a material, or the effect of a special hardening or softening treatment that the material has undergone for its intended use. A fixing device is required during metal hardness testing. However, existing fixing devices are not convenient for effectively fixing metal plates of different sizes, and the fixing method is relatively cumbersome, resulting in cumbersome and unstable replacement of new metal plates, which reduces testing efficiency and increases the probability of detection errors. It is also inconvenient to move the fixed metal plate horizontally, making it difficult to detect hardness differences in different areas of the metal plate. Therefore, we propose a horizontal adjustment fixing device for metal hardness testing to solve this problem. Utility Model Content

[0010] Preferably, two groups of sliding grooves are provided on the top of the placement plate, and the two groups of fixing rods are respectively slidably installed inside the corresponding sliding grooves, and the two groups of sliding grooves are adapted to the corresponding sliding rods.

[0011] The present invention relates to a horizontal adjustment fixing device for testing metal hardness, which is provided with a clamping fixing assembly, a slide groove and a placing plate, and drives an electric push rod to drive the electric push rod to drive the movable plate located on the left side to slide on the two sets of limit blocks. At this time, the left movable plate is moved and the grab plate is rotated by the hinge between the connecting rod, the movable plate and the rotating plate, and then the movable plate located on the right and the movable rod plate on the left are moved relative to each other through the connecting rod, so that the two sets of fixing rods drive the clamping plate on the top side to move relative to each other, so that metal plates of different sizes can be effectively fixed, without the need to prepare a specific fixing device for each specification of metal plate, and metal plates of different sizes can be quickly clamped and fixed, saving the time of replacing the device, thereby improving the overall efficiency of testing, and stable and appropriate clamping and fixing can ensure that the metal plate does not shift or shake during the testing process, so that the testing result is more accurate and reliable;

[0012] In the present invention, a horizontal adjustment and fixing device for metal hardness detection is provided with a screw rod, a motor, a slider and a limit rod. By driving the motor, the motor drives the screw rod to rotate, so that the screw rod drives the outer threaded block to move, and the threaded block drives the placement plate on one side to move horizontally left and right. At this time, it is convenient to perform hardness detection on multiple parts of the clamped and fixed metal plate, and different positions of the metal plate can be detected to obtain more comprehensive hardness data, avoiding inaccurate evaluation due to a single detection position. It can detect the hardness difference in different areas of the metal plate, which is helpful to discover possible local quality problems or unevenness, and can detect multiple parts under the same conditions, reducing detection errors caused by repeated clamping or position changes.
