Embodiment 1

[0035] According to attached figure 1 , figure 2 As shown, the electric Webster hardness tester includes a control system, a power actuator, and a probe device; the control system is connected to and drives the power actuator, and the power actuator is connected to and drives the probe device to be placed on the anvil 6 The test piece 17 is tested for contact pressure hardness.

[0036] Figure 5 As shown, the control system includes a power supply battery pack 23, a control board 24, a micromotor 22, the control board is powered by the power supply battery pack connected to it and the control board is connected and controls the work of the micromotor; the control board is also connected with Handle 7 with switch 8. Using a micro motor as the power, you only need to press the switch lightly with your fingers to realize the detection operation, which greatly reduces the labor intensity of the inspectors during batch detection; one-button operation is adopted for the detecti...

Abstract

The invention relates to an electric Wechsler hardness tester, which comprises a control system, a power execution mechanism and a measuring head device, wherein the control system is connected with the power execution mechanism and drives the power execution mechanism; and the power execution mechanism is connected with a tested piece and drives the measuring head device to detect the contact pressure hardness of the tested piece arranged on an anvil block. The electric Wechsler hardness tester has the characteristics of high stability, low labor intensity, high measurement accuracy, simple calibration operation, low detection error, high detection precision and the like.

Description

technical field [0001] The invention relates to a hardness tester, in particular to an electric Webster hardness tester used for detecting hardness values ​​in the metal profile industry. Background technique [0002] At present, the clamp-type Webster hardness tester used in the inspection of the metal profile industry has problems such as poor stability and high labor intensity caused by artificial force during the inspection, especially when the inspection batch is large, its disadvantages are particularly serious. The specific performance is as follows: [0003] The operation is completely dependent on artificial force, which greatly increases the labor intensity of the inspectors during batch inspection; [0004] There is no probe pressure protection device, which increases the detection error caused by human factors and reduces the measurement accuracy; [0005] There is no disassembly-free hardness value calibration technology, and the instrument calibration is cumb...
