Description

[0002] When cutting processing equipment is processed, the cutting tool holder used by the cutting processing equipment uses the attached cutting fluid system to process and cool the turning tool on the cutting tool holder. However, the cutting fluid spray pipe of the existing cutting processing equipment is made of plastic material, and the overall structure is a gourd-shaped pipe composed of multiple joint heads, which is convenient for twisting and bending to the spraying area. However, when the cutting fluid is circulated and sprayed, the temperature of the cutting fluid will rise due to the heating during milling. When the temperature of the cutting fluid is too high, the spraying pipe will soften under the continuous flow of cutting fluid, causing the joint heads in the pipe to loosen and no longer be fixed towards the spraying area. Moreover, the joint heads inside the plastic spraying pipe will wear out after a long period of use, causing the fixing force to decrease. When the cutting fluid spraying pressure increases, the pipe is easily bent and cannot accurately spray.

[0003] However, in order to allow the cutting fluid spray pipe to be used stably for a long time, manufacturers propose to use solid metal as the material for production. However, the rigidity of solid metal is quite different from that of plastic, and the internal structure cannot be designed according to the cutting fluid spray pipe made of plastic. The designed cutting fluid spray pipe is assembled by multiple joint pipe assemblies that are mutually sleeved. Since the material is solid metal, the rigidity is large, which causes wear at the connection between the multiple joint pipe assemblies during long-term use and frequent adjustment of the cutting fluid spray pipe towards the spraying area, resulting in leakage of the cutting fluid when sprayed, and thus the workpiece cannot be effectively cooled.
