Embodiment Construction
[0015] refer to Figure 1 to Figure 3 , the present invention relates to a fixture for pre-coating of laser cladding samples, including a U-shaped base 1 composed of a groove bottom and two side walls. The base plate 2 of the sample 4 has a side plate 3 on both sides of the base plate, and the side plate is driven to move laterally by the bolt 6 screwed on the corresponding side wall of the U-shaped base. The distance from the upper surface of the test specimen forms the preset coating thickness.
[0016] Two positioning holes are provided on the bottom side of the above-mentioned base plate, and a rotating head 5 is installed in the described positioning hole, and one end of the rotating head is screwed with a coaxial bolt 6, and the other end of the bolt is screwed On the bottom of the U-shaped base.
[0017] The above-mentioned side plate is also provided with two positioning holes, and a rotating head 5 is also installed in the described positioning hole, and one end of ...

The invention relates to a clamp for a laser cladding sample preset coating. The clamp comprises a U-shaped base formed by a tank bottom and two lateral walls, and is characterized in that a substrate, which can move longitudinally and is used for mounting a flat sample, is arranged in the U-shaped base; two lateral plates are arranged at two sides of the substrate respectively, and are driven to move transversely by virtue of bolts which are in screwed connection with the corresponding lateral walls of the U-shaped base; the distance between the upper surface of the substrate and the upper surface of the flat sample forms the thickness of the preset coating. The clamp is simple in structure, is small and convenient, is made of an organic glass plate, is convenient for processing and assembly, and is low in cost; the size of the flat sample can be changed in a certain range, and the adaptability is high; the lateral plates and the substrate are convenient to detach and assemble, and are convenient to clean in time.
Description
technical field [0001] The invention relates to a device for ensuring the thickness of a preset coating, in particular to a fixture for a laser cladding sample preset coating. Background technique [0002] At present, the laser cladding preset coating in the laboratory mainly adopts the method of manual coating, which is difficult to ensure the accuracy and uniformity of the coating thickness. [0003] Most of the existing patent documents are aimed at how to coat the coating, that is, how to obtain a relatively uniform and dense coating. [0004] The most common samples for laser cladding prepared in the laboratory are flat plates, and the length, width and height of the samples are different. In laser cladding, the coating thickness has a certain influence on the quality of the formed coating. Contents of the invention [0005] The invention provides a fixture for pre-coating of laser cladding samples, which can be adapted to the clamping of flat samples of different v...
