Description

Spraying protection frock Technical Field The utility model relates to the technical field of scroll compressors, in particular to a spraying protection tool. Background The known scroll is an important part in a scroll compressor, and because the conventional aluminum alloy base material is difficult to meet the performance requirements of high-speed rotation, corrosion resistance, wear resistance and the like, the performance and the service life of the part are often improved by spraying lubricating coating (such as PTFE (polytetrafluoroethylene) and MoS (multimedia) of a wear-resistant/corrosion-resistant coating) on the surface of the part, in the manufacturing process of the scroll, in order to accurately protect a non-sprayed area, the coating is ensured to cover only a specified position (such as a scroll tooth working surface, an end surface and the like) so as to avoid polluting other areas (such as an assembly surface, a positioning hole, an exhaust port and the like), and further, a spraying protection tool is used as a protection measure. However, in actual use, the existing spraying protection tool for the vortex plate lacks positioning and fixing measures, so that the spraying position of a product is difficult to control, and the assembly is influenced. Disclosure of utility model In order to overcome the above-mentioned drawbacks of the prior art, an embodiment of the present utility model provides a spraying protection tool to solve the above-mentioned problems in the prior art. In order to achieve the aim, the utility model provides the technical scheme that the spraying protection tool comprises an upper main body and a lower main body; The middle part of the upper main body is provided with a through circular through hole, and one end face of the upper main body is provided with an annular step; One end face of the lower main body is set to be an opening end face, a heat dissipation groove is formed in the opening end face, a plurality of evenly distributed heat dissipation holes communicated with the heat dissipation groove are formed in the side face of the lower main body, and a square groove communicated with the heat dissipation groove and used for fixing is formed in the other end face of the lower main body. Further, the upper body and the lower body are each provided in a disk shape. Further, the number of the annular steps is the same as the number of the limiting blocks, and at least 4 annular steps and at least 4 limiting blocks are arranged. Further, the annular grooves between two adjacent limiting blocks are arranged to be positioning slots, and the central axes of the positioning slots are coincident with the central axes of the adjacent annular steps. Further, the length and width of the positioning slot are not larger than the length and width of the annular step. Further, the number of the heat dissipation holes is at least 4. The utility model has the technical effects and advantages that: Compared with the prior art, the positioning step of the auxiliary scroll plate accurately positions and fixes the scroll plate through the annular groove and the limiting block, spraying operation is convenient, spraying uniformity and quality can be guaranteed, the circular through holes are utilized to enable the scroll molded lines of the scroll plate to be sprayed during spraying processing, other areas on the scroll plate are effectively protected, further, the spraying-forbidden areas are prevented from being adhered with a coating, spraying working efficiency is improved, spraying quality is guaranteed, and through the arrangement of the radiating holes, surface drying time after paint spraying is finished can be reduced, so that spraying speed of the scroll plate is improved, and cost of a spraying process is reduced.
