Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying cup processing, in particular to a cutter for processing cup teeth. Background Art

[0002] In the process of surface treatment, in electrostatic spraying, through an electrostatic field, after the paint is charged, it is adsorbed onto a workpiece with the opposite polarity, and the film thickness on the surface of the workpiece can be better controlled. According to different paints, electrostatic spray guns can be divided into paint electrostatic spray guns and powder electrostatic spray guns. Among them, a paint electrostatic spray gun consists of a nozzle and a gun body. On the gun head of the electrostatic spray gun, high-voltage static electricity is connected, causing strong corona discharge in the area near the gun head, so that the paint passes through this area and is charged. Then, the paint liquid flows from the nozzle of the atomization device into the rapidly rotating paint spraying cup, and the paint liquid flows through the gap between the housing and the distribution plate by centripetal force. In the inner cone of the cup and disk, the paint liquid will be evenly distributed and flow to the edge. At the edge, the paint liquid will break away from the cup and disk and be atomized into fine droplets. According to different models of the cup and disk, the edge is divided into smooth, single serrated or cross serrated. However, currently, when processing cup teeth on the edge of the port of the cup and disk, there are originally 508 gears in the processing technology of the cup, and it takes about 3 hours through the original five-axis CNC process. Therefore, the processing time needs to be shortened. Thus, a cutter for processing cup teeth is provided to solve the above problems. Summary of the Utility Model

[0017] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings. In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components.

[0019] The present utility model will be further described below with reference to the accompanying drawings.

[0020] Please refer to Figures 1 - 5 , a rotary cup tooth processing tool of the present utility model includes: a rotary cup main body 3 and a tool. The tool includes a tool handle 1 and a tool head 2. The tool head 2 is disposed at the end of the tool handle 1. The tool head 2 extends to one end outside the circumference of the tool handle 1 to form a cutting edge 5. A first inclined surface 6 is disposed on the outside of the end of the tool head 2 away from the tool handle 1, and a second inclined surface 7 is disposed on the outside of the end of the tool head 2 close to the tool handle 1. The included angle β between the first inclined surface 6 and the second inclined surface 7 is 103° (as Figure 4 ).

[0021] Combined with Figure 2 and Figure 3 shown, where a sharp edge is formed at the intersection of the first inclined surface 6 and the second inclined surface 7, and the sharp edge surrounds the outside circumference of the tool head 2. Thus, not only the structure of the cutting edge 5 is made more solid, but also the cutting process becomes smoother. An opening 8 is provided at the opposite end of the tool head 2 and the cutting edge 5. Through the opening 8, not only the heat dissipation area of the tool head 2 is increased, but also the overall weight of the tool head 2 is reduced, so that the waste chips at the cutting part can be discharged in time while ensuring the structural strength of the tool head 2. Moreover, the opposite side of the tool head 2 and the tool handle 1 is a circular slope structure, and a slope 9 is provided on one side of the tool handle 1 located at the tool head 2. The included angle between the slope 9 and the cutting edge 5 is an obtuse angle, which is convenient for the tool head 2 to process the rotary cup tooth main body 4.

[0022] Combined with Figure 1 and Figure 5 shown, where the rotary cup main body 3 is provided at the tool head 2. The tool head 2 is located at the port of the rotary cup main body 3. The tool handle 1 on the tool is fixedly installed on the machining head of a numerical control machine tool, and the rotary cup main body 3 is installed on the machining position to be processed on the numerical control machine tool. The rotary cup tooth main body 4 is provided through the tool head 2 on the inner circumference of the port of the rotary cup main body 3. The number of the rotary cup tooth main bodies 4 is set to several. Thus, when processing 508 gears of the original rotary cup with this tool, it only takes 1 minute to complete the processing.

[0023] The above are only the preferred embodiments of the present utility model.
