[0002] With the rapid development of the electric vehicle industry, battery trays, as key components for supporting and protecting battery packs, have increasingly stringent performance requirements. They not only need to have sufficient strength and rigidity to withstand loads under various working conditions, but also need to have good corrosion resistance and thermal conductivity to ensure stable operation and long life of the battery pack. During the production process of battery trays, when arc spraying technology is used for surface treatment, high-energy arc discharge will generate strong noise, posing a threat to the hearing health of operators, and also affecting the comfort and work efficiency of the production environment.

[0003] At present, in order to solve the noise problem during arc spraying, a Chinese patent with the announcement number CN203700479U discloses an arc spraying silencer, which is composed of a base, an outer wall sleeve, a porous sound-absorbing material, a perforated pipe, and a hoop. The silencer can be directly installed on the nozzle of the arc spray gun, and cooperates with the porous sound-absorbing material to reduce noise pollution from the source, which can effectively reduce the noise pollution during arc spraying.

[0004] However, the nozzles of some existing arc spray guns are trumpet-shaped. When installing, the above-mentioned prior art connects the base with the nozzle of the arc spray gun and fixes it with bolts. It is complicated to disassemble and assemble, and is not suitable for trumpet-shaped spray gun nozzles, so the versatility is poor.

[0005] Therefore, the present application provides an arc spraying silencer to solve the above technical problems. Utility Model Content

[0033] like Figure 1 and Figure 3As shown, an embodiment of the utility model provides an arc spraying silencer, comprising a sleeve 1, a spraying channel 2 is arranged in the middle of the sleeve 1, an annular edge 101 is constructed on the outer side of one end of the sleeve 1, and two symmetrically arranged substrates 3 are matched on the side of the annular edge 101 away from the sleeve 1, and a clamping plate 6 is arranged on the inner side of the two substrates 3, and a screw rod 7 that passes through the middle of the substrate 3 is rotatably installed in the middle of the clamping plate 6, and a screw cap is fixed on one end of the screw rod 7 that extends out of the substrate 3, and limiting rods 8 that directly pass through the two ends of the substrate 3 are fixed at both ends of the clamping plate 6, so that the clamping plate 6 can be driven to move by rotating the screw rod 7, and the clamping plates 6 on the inner sides of the two substrates 3 are used to clamp and fix on the barrel of the arc spray gun.

[0034] The ends of the two substrates 3 are fixed with a limiting column 4 that passes through the annular edge 101.

The spring 5 elastically abuts the annular edge 101 in the direction of the substrate 3, so that the sleeve 1 can be elastically installed on the end of the substrate 3.

[0035] In a specific implementation, the spring 5 is sleeved on the limiting column 4, one end of the spring 5 is fixed on the fixing plate 401, and the other end abuts against the annular edge 101, so that when the substrate 3 is fixed on the barrel of the arc spray gun, the sleeve 1 can be elastically installed at the muzzle and elastically docked with the muzzle.

[0036] Cooperate with Figure 2 and Figure 4 As shown, a plurality of silencer grooves 201 are provided on the inner wall of the spray channel 2, and a docking bucket 202 is fixed at the end of the spray channel 2 facing the substrate 3, and the docking bucket 202 can be used to dock with the trumpet-shaped muzzle of the arc spray gun.
