[0001] This utility model relates to the field of mineral testing technology, specifically a portable mineral hardness tester stand. Background Technology

[0002] Mineral hardness testers are instruments used to determine the hardness of minerals or materials. They mainly include Vickers / Knoop hardness testers, which use a diamond indenter to leave an indentation on the sample surface and calculate the hardness by measuring the diagonal under a microscope; and Rockwell hardness testers, which calculate the hardness by measuring the difference in indentation depth of the indenter under different loads.

[0003] In existing technologies, when conducting hardness testing, the mineral is usually placed on a table, then scribing is performed, and the results are compared to obtain the corresponding hardness data.

[0004] During the testing process, the minerals are prone to shaking, which can reduce the accuracy of the measurement and make subsequent operations difficult. Utility Model Content

[0048] Reference Figure 1 and Figure 2The top wall of the support plate 24 is provided with locking components 25. Multiple locking components 25 are provided and are evenly distributed circumferentially along the axial direction of the support plate 24. The locking components 25 include a fixed seat 251, a first telescopic rod 252 and a locking plate 253. The fixed seat 251 is fixed to the top wall of the support plate 24 by welding. The telescopic direction of the first telescopic rod 252 is radial to the support plate 24. The two ends of the first telescopic rod 252 are fixedly connected to the fixed seat 251 and the locking plate 253 respectively. In this embodiment, the locking plate 253 is preferably a right-angled triangular plate. One right-angled side of the locking plate 253 is attached to the top wall of the support plate 24 and the other right-angled side is attached to the first telescopic rod 252.

[0049] Reference Figure 1 and Figure 2 The horizontal surface of the stepped section of the locking plate 253 is provided with an installation groove 254, and each installation groove 254 is provided with a filler strip 255. In this embodiment, the filler strip 255 is preferably a right-angled triangular strip, and the filler strip 255 can fill the stepped part of the locking plate 253 to make the stepped part transition smoothly.

[0050] The operator places the mineral on the surface of the support plate 24. At this time, the locking plates 253 slide in opposite directions. The operator can choose a smooth flat surface or a stepped surface according to the surface of the mineral to fix the mineral.

[0051] Reference Figure 1 and Figure 3 Each side wall of the fixed frame 14 is provided with a locking device 3. The locking device 3 includes a screw 31, wherein the screw 31 is horizontally arranged and the axis of the screw 31 is perpendicular to the side wall of the fixed frame 14. The screw 31 passes through the side wall of the fixed frame 14 and is threadedly connected to the fixed frame 14. A handwheel is provided at one end of the screw 31 that is inserted into the outer side of the fixed frame 14. The handwheel and the screw 31 are coaxially fixedly connected.

[0052] Reference Figure 1 and Figure 3 The end of the screw 31 is provided with an abutment component 32, which includes a support plate 321 and a mounting plate 322. In this embodiment, both the support plate 321 and the mounting plate 322 are circular plates. The screw 31, the support plate 321 and the mounting plate 322 gradually approach the mineral to be detected along the axial direction of the screw 31. The support plate 321 is coaxially fixedly connected to the screw 31 by a key connection, and the mounting plate 322 is coaxially rotatably connected to the support plate 321 by a bearing connection.

[0053] Reference Figure 1 and Figure 3The mounting plate 322 has abutment members 33 arranged in an array on the end face away from the support plate 321. The abutment members 33 include a second telescopic rod 331 and an abutment plate 332. The second telescopic rod 331 is rotatably connected to the mounting plate 322 through a hinge seat. The end of the second telescopic rod 331 away from the hinge seat is fixedly connected to the abutment plate 332. The end of the abutment plate 332 away from the second telescopic rod 331 is provided with a flexible pad. The flexible pad and the abutment plate 332 are fixedly connected.

[0054] The operator drives the support plate 321 to move by rotating the screw 31, and makes the mounting plate 322 abut against the side wall of the ore. Then, the abutment plate 332 abuts against the surface of the ore to complete the limiting of the middle part of the ore.

[0055] Reference Figure 1 and Figure 3 The detection device 4 includes an adjusting rod 41 and a mounting frame 42.

[0057] Operators can adjust the position of the hardness tester by sliding the adjustment rod 41 to facilitate testing from multiple angles.

[0058] The operating principle of a portable mineral hardness tester stand is as follows: the operator first adjusts the support column 13 and determines whether a filler strip 255 is needed based on the surface of the ore.

[0059] The ore is then placed on the surface of the bearing plate 24, and then the locking operation is completed by the locking plate 253. At the same time, the handwheel is rotated to drive the screw 31 to rotate, and the mounting plate 322 is brought close to the ore, and the abutment plate 332 abuts against the ore to complete the limiting of the ore.

[0060] Then, by adjusting the positions of the mounting bracket 42 and the mounting rod 43, the hardness tester is moved and installed to perform the corresponding testing operations and obtain more accurate data.
