Description

Technical Field

[0001] The utility model relates to the technical field of production and polishing of high-density tooth internal thread copper tubes, in particular to polishing equipment for the production of high-density tooth internal thread copper tubes. Background Art

[0002] Internally threaded copper tube, also known as non-smooth tube, refers to an internally threaded TP2 copper tube with a smooth outer surface and a certain number of regular threads on the inner surface. High-density teeth mean that the number of internal threads is higher and denser. Due to the increase in the inner surface area of the internally threaded copper tube, its thermal conductivity is 20 to 30 percent higher than that of the smooth tube. With the global energy shortage and the implementation of the domestic energy efficiency air conditioning access system, internally threaded copper tubes will be widely used in the air conditioning and refrigeration industry. In the production process of high-density tooth internally threaded copper tubes, in order to make their surface smooth, grinding equipment is often needed to polish their surface.

[0003] When using existing grinding equipment, the high-density internal thread copper tube to be ground is usually fixed on the fixture of the equipment, and then the grinding disc at one end of the grinder rotates at high speed to polish the surface of the fixed high-density internal thread copper tube;

[0004] However, when the above method is used to grind the high-density tooth internal thread copper tube, since the high-density tooth internal thread copper tube is usually cylindrical, it is often necessary to rotate the high-density tooth internal thread copper tube to adjust the angle in order to fully grind its surface. Rotating the high-density tooth internal thread copper tube requires multiple loading and unloading of the fixed high-density tooth internal thread copper tube to adjust the angle of the high-density tooth internal thread copper tube. The operation is cumbersome, time-consuming and labor-intensive, and the efficiency of the grinding process is also relatively low. Therefore, those skilled in the art provide a grinding device for high-density tooth internal thread copper tube production to solve the problems raised in the above background technology.
