One end of the first limiting spring 22 is fixed to the third limiting plate 20, and the other end abuts against the first support plate 16.
[0027] The fourth limiting module includes a fourth limiting plate 7, which is vertically fixed on the detection support plate 3. Several second connecting through holes are provided on the fourth limiting plate 7. A second adjusting screw assembly 13 is movably inserted into the second connecting through holes.

[0028] In this embodiment, the first limiting device and the second limiting device can limit and clamp the detection materials of different sizes of cutting tools.
[0029] Several sliding limit rod assemblies 24 are fixed to the detection bracket 1, and the support platform 2 is slidably locked onto the sliding limit rod assemblies 24. A telescopic cylinder 25 is horizontally provided on the front side of the detection bracket 1, and the piston rod of the telescopic cylinder 25 is fixed to the support platform 2. In this embodiment, the telescopic cylinder 25 can adjust the position of the support platform 2, thereby adjusting the relative position of the pressure head 31 and the tool material, realizing the detection of multiple positions and improving the detection accuracy.
[0030] A rotating motor 26 is vertically upwardly mounted at the bottom of the support platform 2, and the rotor of the rotating motor 26 is fixedly connected to the bottom of the detection support plate 3. In this embodiment, the rotating motor 26 can adjust the angle of the detection support plate 3, thereby allowing the pressure head 31 to act on different positions on the tool material.
[0031] The pressure application device includes a portal frame 27, which is fixed to a detection support frame. A pressure application cylinder 28 is vertically mounted on the portal frame 27, and a pressure application support plate 29 is movably mounted inside the portal frame 27.

A pressure application head 31 is detachably fixed to the pressure application support plate 29. In this embodiment, the pressure application cylinder is used to apply the pressure application head 31 to the surface of the tool material. During the detection process, the pressure sensor 30 is used to detect the pressure between the pressure application head 31 and the tool material, thereby facilitating pressure control. The pressure application head 31 is detachably fixed to the pressure application support plate 29 for easy replacement.
[0032] In this embodiment, a distance sensor is provided on the detection bracket 1 at a position opposite to the pressure support plate 29, which can be used to detect the distance that the pressure head 31 moves downward.
[0033] Working principle: Place the tool material on the detection support plate 3, tighten the first limiting screw 8 and the second limiting screw 9, and bring the first limiting plate 10 and the second limiting plate 11 against the front and rear sides of the tool material respectively. Then loosen the first limiting nut group 14 and the second limiting nut group 15, adjust the length of the first adjusting screw group 12 and the second adjusting screw group 13 respectively, pull the first limiting post 18 and the second limiting post 19, and bring the third limiting plate 20 and the fourth limiting plate 21 against the top of the tool material respectively. Through the above operation, the tool material can be limited from multiple angles, and the tool material of different sizes can also be limited.
[0034] After the limit is completed, the pressure cylinder 28 is activated to move downward, so that the pressure head 31 applies a certain pressure to the surface of the tool material. The position between the tool material and the pressure head 31 is adjusted by the telescopic cylinder 25. The pressure is applied repeatedly, and multiple sets of data are sampled.
[0035] After the pressure is applied, the hardness value of the tool can be determined by measuring the depth of the indentation on the tool material.
