Problems solved by technology

[0002] Hardness tester is a testing machine used to measure the hardness value of materials. It is convenient for experimenters to grasp the properties of metal materials. It is widely used in the mechanical field. Now the hardness testers on the market have different application fields, and some of the principles are also different, but Usually the end of the measurement is only the result, it is inconvenient to observe the sample, and the measurement process is vague. The application number is CN201020527644.3, which discloses a hardness tester. The upper end of the main shaft with the indenter installed on the lower end is connected with a pressure sensor; Rollers are provided, and the rollers are mounted on the front end of the large lever, and the rear end of the large lever is fixedly connected with a bearing seat, and the second rolling bearing in the bearing seat is connected with a screw nut fixing seat through a connecting shaft, and a ball is fixedly installed on the screw nut fixing seat Screw nut, the lower end of the ball screw matched with the ball screw nut is connected with a stepping motor through a coupling. After the control device detects the signal that the sample is clamped through the pressure sensor, it controls the stepping motor to work, and the hardness tester implements automatic Loading action; this type of hardness tester can only measure the hardness of the sample at one temperature, and it is not convenient to fully grasp the performance of the sample

Embodiment Construction

[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0013] Such as figure 1 with figure 2 As shown, a temperature-adjustable hardness tester includes a base 1, an upper mounting frame 2, a sample stage 3 and a measuring device 4. The upper mounting frame 2 is arranged above the sample stage 3, and the distance between the sample stage 3 and the base 1 is The height difference is 90~100mm. The measuring device 4 includes an objective lens 5, a mechanical adapter 6 and a camera 7. The mechanical adapter 6 is arranged in the upper mounting frame 2. The upper end of the camera 7 and the mechanical adapter 6 connected, the objective lens 5 is connected to the lower end of the mechanical socket 6, and a control system 8 is arranged beside the sample stage 3, and the control system 8 is electrically co...
