Description

Technical Field

[0001] This utility model relates to the field of coating spraying, and more specifically, to a sprayer for coating gear cutting tools. Background Technology

[0002] Cutting tools are a common tool in daily life. In mechanical manufacturing, tools used for cutting are called cutting tools. Since cutting tools used in mechanical manufacturing are basically used to cut metal materials, special coatings are often sprayed onto the surface of the cutting tools by spraying them with a spraying device to reduce tool wear and increase the tool's wear resistance.

[0003] Application CN 221413588 U discloses a tool coating spraying device, relating to the field of spraying device technology. It includes a reaction chamber and a tool disc. A rotating shaft is mounted on the bottom of the tool disc, and a motor is connected to one end of the rotating shaft. A multi-stage telescopic push rod is installed at the bottom of the motor. A retaining ring is installed on the outer side of the tool disc. A limiting ring is machined at the bottom of the tool disc. A first sliding sleeve is machined at the bottom end of the tool disc, and a second sliding sleeve is sleeved on the outside of the first sliding sleeve. A base plate is machined at one end of the second sliding sleeve. The key technical point is that the reaction chamber is fixed using multiple mounting bolts. When the multi-stage telescopic push rod controls the tool disc to extend into the inner side of the reaction chamber through the base plate, motor, and rotating shaft to await spraying, the limiting ring moves with the tool disc, causing the retaining ring to extend upwards into the inner side of the reaction chamber, so that its outer wall fits against the inner wall of the reaction chamber. This seals multiple through holes in the inner wall of the reaction chamber, saving materials and preventing pollution of the working environment.

[0004] The aforementioned disclosed structure uses a complex structure for spray protection, lacking a semi-cylindrical structure for collecting the coating. This not only hinders the separate positioning for coverage and protection, affecting its use, but also makes it difficult to provide auxiliary support for the cutting tools, affecting the stability of the rotating spray. Furthermore, the excess coating sprayed out is not easily collected and processed, resulting in waste. The structure has poor adaptability and needs improvement. Utility Model Content
