In the process, the solid particles are accelerated to above 300 m/s. Compared with other thermal spraying technologies, the cold spraying has the greatest advantage of lower process temperature (about 1100 ℃ at most), and adverse reactions such as particle oxidation and decomposition can be greatly reduced. Because of no large heat input, the coating prepared by cold spraying maintains the original components, structure and performance of the material. The metal coating prepared by cold spraying can be widely applied to the fields of aerospace, marine ships, rail transit, biomedical treatment, electromagnetic shielding, part repair and the like.

The use process of the clamping device of the isolating switch electric contact comprises the following steps:
the electrical contacts 20 are mounted on the device. It should be understood that the location at which the clip 12 grips the electrical contact 20 may vary depending on the spray application requirements. In a specific embodiment of the invention, the lengths of the first telescopic rod 1, the second telescopic rod 2 and the third telescopic rod 3 are adjusted, so that the U-shaped end of the electrical contact 20 is sleeved on the carrier roller 4 and positioned between the two rollers 7 and between the carrier roller 4 and the rollers 7, and the distance between the electrical contact 20 and the spray gun 21 can be adjusted; the lengths of the fourth telescopic rod 8 and the fifth telescopic rod 9 are adjusted to make the third rotating shaft 10 and the fourth rotating shaft 11 located in the U-shaped opening and between the two clamping pieces 12. Then, the lengths of the second telescopic rod 2 and the third telescopic rod 3 are adjusted, so that the two opposite ends of the two rollers 7 respectively abut against two sides of the spraying position of the electrical contact 20, and simultaneously, the wheel surfaces of the rollers 7 are in pressure contact with the surface of the electrical contact 20, so that the rollers 7 and the carrier rollers 4 clamp the electrical contact 20. The length of the fifth telescopic rod 9 is adjusted, the third rotating shaft 10 (and/or the fourth rotating shaft 11) is driven to rotate, the depth of the fourth rotating shaft 11 inserted into the third rotating shaft 10 is changed, and the distance between the two clamping pieces 12 is adjusted, so that the two clamping pieces 12 abut against two sides of the electrical contact 20, and the electrical contact 20 is clamped. The spray gun 21 of the spray printing device is generally positioned directly above the carrier roller 4 and between the two rollers 7. The spraying position is located between the two rollers 7. When other positions of the electrical contact 20 need to be sprayed, the first rotating shaft 5 and the second rotating shaft 6 can be driven to rotate, so that the carrier roller 4 and the roller 7 rotate, the electrical contact 20 is driven to move, the lengths of the first telescopic rod 1, the fourth telescopic rod 8 and the fifth telescopic rod 9 are changed, the fourth telescopic rod 8 is moved, and the like, so that the position of the surface of the electrical contact 20 opposite to the spray gun 21 can be changed, and other positions of the electrical contact 20 can be sprayed. Furthermore, the rolling of the roller 7 makes it possible to maintain the powder sprayed by the gun 21 vertically deposited in the spraying position. It should be understood that the electrical contacts 20 may be reinstalled to spray other locations of the electrical contacts 20. For example, when it is desired to spray a surface where the U-shaped open end of the electrical contact 20 is located, the fourth telescopic rod 8 and the fifth telescopic rod 9 may be adjusted, and the position of the fourth telescopic rod 8 may be moved so that the fourth telescopic rod 8 and the fifth telescopic rod 9 are located below the idler 4, the idler 14 still passes through the U-shaped opening of the electrical contact 20, the clip 12 clamps the open end of the lower side plate of the U-shape of the electrical contact 20, and the spray gun 21 sprays a surface facing the open end of the upper side plate of the U-shape of the electrical contact 20, so that the surface may be sprayed.
In the manner, the carrier roller 4 and the rollers 7 are parallel, so that the spraying area between the two rollers 7 is parallel, and the spraying powder can be vertically deposited on a spraying surface. Because the electrical contact 20 is arc-shaped, the repair surface of the electrical contact 20 is arc-shaped, when the spraying area of the electrical contact 20 is ensured to be a plane, the heights of other positions need to be changed correspondingly, so that the lengths of the fourth telescopic rod 8 and the fifth telescopic rod 9 are adjusted in real time in the clamping process, the fourth telescopic rod 9 is moved, the third rotating shaft 10 and/or the fourth rotating shaft 11 are rotated, the position of the electrical contact 20 is changed along with the movement of the electrical contact 20, the arc-shaped surface, which is not sprayed, of the electrical contact 20 is moved to the position below the spray gun 21, comprehensive spraying is realized, and the quality and the deposition efficiency of a sprayed deposition layer are improved.
In summary, the clamping device for the electrical contact of the disconnecting switch according to the embodiment of the invention is adapted to the electrical contacts with different sizes and radians by adjusting the components of the first clamping portion and the second clamping portion before and during spraying, and in the spraying process, the components of the first clamping portion and the second clamping portion can be adjusted according to the sizes and radians of the electrical contacts so as to move the electrical contacts, adjust the spraying position, angle and distance, keep the plane spraying of the electrical contacts, vertically deposit powder on the electrical contacts, improve the deposition efficiency, deposition layer quality and deposition thickness of the spraying, make the thickness of the surface repairing coating uniform and have good performance, realize the surface repairing of the electrical contacts, do not need to move the spraying device, greatly reduce the workload, and have simple and convenient operation.
