[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 of 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 performance detection device for multi-layer laser cladding layers, including a mounting base 1. A mounting groove is provided in the middle of the side surface of the mounting base 1, and an adjustable adjusting plate 3 is provided inside the mounting groove. Two groups of sliding grooves symmetrically arranged with respect to the mounting groove are provided on the side surface of the mounting base 1. A limiting plate 2 for squeezing and positioning the sample is slidably arranged inside each group of sliding grooves. Each group of sliding grooves has two. A jack is provided in the middle of the upper surface of the mounting base 1, and a push plate 4 capable of squeezing the sample is slidably arranged inside the jack. A pressure sensor 41 is provided at the bottom of the push plate 4 for contacting the indenter of an external universal testing machine. Place the device on an external universal testing machine. The universal testing machine squeezes the push plate 4 with the pressure sensor 41, and the push plate 4 squeezes the cladding layer to be squeezed until the cladding layer to be squeezed falls off. The pressure sensor 41 transmits the squeezing force to an external controller, and then the bonding strength can be obtained.

[0019] Further, adjusting bolts 31 are rotatably arranged at positions corresponding to both ends of the mounting base 1 and the adjusting plate 3, and the adjusting bolts 31 are threadedly connected to the screw holes on the adjusting plate 3. Place the fabricated sample into the mounting groove, rotate the adjusting bolts 31, and the adjusting bolts 31 drive the sample to move, so that the bottom of the cladding layer to be squeezed is flush with the side surface of the mounting base 1.

[0020] Further, an elastic column 21 connected to the limiting plate 2 is provided inside the sliding groove for pushing the limiting plate 2 towards the middle of the mounting base 1. The elastic column 21 is a telescopic rod structure with a spring inside; the part of the limiting plate 2 corresponding to the mounting groove protrudes towards the inside of the mounting groove; the elastic column 21 can push the limiting plate 2 to move, and the limiting plate 2 squeezes the upper ends of the side surfaces of the substrate and other cladding layers, thereby completing the fixation of the sample.

[0021] The pressure sensor 41 used in the present utility model is a common electronic component in the prior art, and its working mode and circuit structure are all well-known technologies, so no further description will be given here. The pressure sensor 41 can transmit the detected pressure to an external controller for processing, so as to obtain the bonding strength between layers and between the layer and the substrate.

[0022] When in use:

[0023] It is assumed that there are five layers of laser cladding layers on the substrate, which are the first layer, the second layer, the third layer, the fourth layer, and the fifth layer in sequence from the surface layer to the substrate direction;

[0024] When detecting the bonding strength between the first layer and the second layer, the sample is fabricated into the shape as shown in Figure 4 a, that is: the first layer is the cladding layer to be squeezed, and the second layer to the substrate is the substrate and other cladding layers;

[0025] When detecting the bonding strength between the second layer and the third layer, the sample is supported as shown in Figure 4The shape shown in b, that is: the first layer is the surface cladding layer, the second layer is the cladding layer to be extruded, and from the third layer to the substrate are the substrate and other cladding layers;

[0026] And so on for other layers until the substrate and the cladding layer adjacent to it are detected. At this time, the substrate is made into a convex structure, and the cladding layer on the surface of the substrate can be subjected to extrusion detection;

[0027] The extrusion method for detecting the bonding force between the cladding layers and between the cladding layer and the substrate is as follows:

[0028] Push the limit plate 2 to both sides, and place the made sample into the installation groove. Rotate the adjusting bolt 31, and the adjusting bolt 31 drives the sample to move, and make the bottom of the cladding layer to be extruded flush with the side of the mounting seat 1;

[0029] Release the limit plate 2, and the elastic column 21 pushes the limit plate 2 to move, and makes the limit plate 2 extrude the upper end of the side of the substrate and other cladding layers, so as to complete the fixation of the sample;

[0030] Place the device on an external universal press. The universal press extrudes the push plate 4 with the pressure sensor 41. The push plate 4 extrudes the cladding layer to be extruded until the cladding layer to be extruded falls off, and the pressure sensor 41 transmits the extrusion force to the external controller, and then the bonding force can be known.

[0031] The utility model can adjust the position of the sample to be detected, which is convenient for positioning the sample. It can detect the bonding force between the cladding layers and between the cladding layer and the substrate, so as to detect the performance of the multi-layer cladding layer. The structure is simple and the use is convenient.
