The utility model discloses a power tool turret cooling structure which comprises an air inlet pipe and an oil inlet pipe which penetrate through a tool turret body, and the air inlet pipe and the oil inlet pipe penetrate through the tool turret body and then extend into a bevel gear transmission cavity. A waste gas exhaust pipe is arranged in the middle of the bevel gear transmission cavity, and the gas inlet pipe and the oil inlet pipe are arranged on the two sides of the waste gas exhaust pipe in the bevel gear transmission cavity respectively. The waste gas exhaust pipe abuts against a cavity of the coupler in the tool turret body, an external waste gas exhaust pipe penetrates through the cavity of the coupler and extends out of a shell of the tool turret body, and the waste gas exhaust pipe in the tool turret body is communicated with the external waste gas exhaust pipe. The air inlet pipe is communicated with an external air inlet pipe on the shell of the tool turret body, and the oil inlet pipe is communicated with an external oil inlet pipe on the shell of the tool turret body. The external air inlet pipe is connected with an air blowing pipe on a machine tool, and the inlet end of the external air inlet pipe is connected with an oil inlet pump. The utility model has strong practicability.

This invention relates to a closed-loop axial hydrostatic / hydrostatic bearing spindle system for an inertial friction welding machine. The invention aims to address the problem that in inertial friction welding machines, the system cannot adaptively adjust the oil film thickness of the hydrostatic / hydrostatic thrust bearing according to the magnitude of the axial upsetting force from start to finish, thus failing to form a fully closed-loop system. The spindle system is equipped with opposing double-sided hydrostatic / hydrostatic thrust bearings. One side is a load-bearing hydrostatic / hydrostatic thrust bearing (11), and the other side is a non-load-bearing hydrostatic / hydrostatic thrust bearing (12). The non-load-bearing hydrostatic / hydrostatic bearing (12) acts as a back pressure, improving the oil film stability and stiffness of the load-bearing hydrostatic / hydrostatic thrust bearing (11), increasing welding accuracy, facilitating control of axial shortening, and improving welding stability and efficiency. The specific structure is shown in Figure 1.
