[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4, the utility model provides a technical solution: a support platform for detecting the hardness of a laser cladding layer, which includes a mounting base 1 installed on a hardness tester. A support base 4 with adjustable height is installed on the mounting base 1. A cylinder 5 is provided at the bottom of the support base 4. The telescopic end of the cylinder 5 is installed with a servo motor 6 through a motor base. A support disk 7 is movably installed on the output shaft of the servo motor 6. Uniformly distributed placement grooves 73 are formed on the support disk 7. A number of cladding layer samples of the same size are evenly placed in the placement grooves 73, facilitating the sequential detection of a number of samples.

[0019] When adjusting the position of the sample: control the cylinder 5 to shorten. The cylinder 5 drives the support disk 7 to move upward through the servo motor 6. At the same time, control the servo motor 6 to work. The servo motor 6 drives the support disk 7 to rotate a certain angle, thereby adjusting the position of the sample. Then control the cylinder 5 to reset so that the support disk 7 contacts the upper surface of the support base 4.

[0020] Further, a driving ring 2 is rotatably arranged on the mounting base 1, and a screw rod 3 is threadedly connected inside the driving ring 2. The support base 4 is installed on the top of the screw rod 3.

[0021] Further, the screw rod 3 is of a hollow structure, and a guide rod 31 is movably inserted inside the screw rod 3. The bottom of the guide rod 31 is installed on the hardness tester. Rotate the driving ring 2 to make the screw rod 3 move upward along the length direction of the guide rod 31. The screw rod 3 drives the support base 4 to move upward, and at the same time, the support disk 7 moves upward synchronously with the support base 4.

[0022] Further, the top of the output shaft of the servo motor 6 is of a clamping post structure. A clamping sleeve 71 corresponding to the clamping post structure is provided at the bottom of the support disk 7, and the clamping sleeve 71 is movably sleeved on the clamping post structure of the output shaft of the servo motor 6.

[0023] Further, an annular magnet sheet 72 is provided at the bottom of the support disk 7. Two electromagnets 41 corresponding to the annular magnet sheet 72 are provided on the support base 4. Control the electromagnets 41 to be energized. The magnetic poles of the corresponding surfaces of the electromagnets 41 and the annular magnet sheet 72 are the same and repel each other, so that the support disk 7 moves upward a certain distance along the output shaft of the servo motor 6, and there is a certain gap between the support disk 7 and the support base 4. Then control the servo motor 6 to work at the same time. The servo motor 6 drives the support disk 7 to rotate a certain angle, thereby adjusting the position of the sample. Finally, disconnect the electromagnets 41 to make the support disk 7 automatically fall on the support base 4.

[0024] The electromagnets 41 and servo motors 6 used in the utility model are both common electronic components in the prior art. Their working methods and circuit structures are all well-known technologies and will not be elaborated here. The electromagnets 41 and servo motors 6 are both electrically connected to the internal controller of the used hardness tester.

[0025] When in use:

[0026] Place several cladding layer samples of equal size evenly in the placement groove 73. Rotate the driving ring 2 to move the screw rod 3 upward along the length direction of the guide rod 31. The screw rod 3 drives the support base 4 to move upward. At the same time, the support disk 7 moves upward synchronously with the support base 4. At this time, one sample is located directly below the indenter.

[0027] Control the hardness tester to work, so that the indenter extrudes the sample, and then adjust the hardness tester to detect the hardness of the sample.

[0028] After the detection is completed, adjust the position of the sample to facilitate the detection of other samples. The sample position adjustment method is as follows:

[0029] Adjustment method 1: Control the cylinder 5 to shorten. The cylinder 5 drives the support disk 7 to move upward through the servo motor 6. At the same time, control the servo motor 6 to work. The servo motor 6 drives the support disk 7 to rotate a certain angle, so as to adjust the position of the sample. Then control the cylinder 5 to reset so that the support disk 7 contacts the upper surface of the support base 4.

[0030] Adjustment method 2: Control the electromagnet 41 to be energized. The surfaces of the electromagnet 41 corresponding to the annular magnet sheet 72 have the same magnetic poles and repel each other, so that the support disk 7 moves upward a certain distance along the output shaft of the servo motor 6, and there is a certain gap between the support disk 7 and the support base 4. Then control the servo motor 6 to work at the same time. The servo motor 6 drives the support disk 7 to rotate a certain angle, so as to adjust the position of the sample. Finally, disconnect the electromagnet 41 to make the support disk 7 automatically fall on the support base 4.

[0031] The utility model can position and place multiple samples, without repeating the calibration of the position of each sample, facilitating the rapid detection of the hardness of multiple samples in sequence, which can effectively improve work efficiency, is simple to operate and convenient to use.
