[0002] The turning and milling power tool holder is a kind of power head on the turning and milling compound machine tool, which is installed on the power tool turret of the turning and milling compound machine tool. The driving motor in the power tool turret is used to drive the tool on the turning and milling power tool holder to rotate, so as to carry out turning and milling processing on the workpiece.

[0003] There has always been a problem of poor chip evacuation during the turning and milling process of ordinary power tool holders, and the low machining accuracy of the part surface caused by poor stability during the gear transmission process. During the turning and milling process, since the water nozzle spraying position is on the side of the cutting position of the power tool holder, it cannot directly cool and lubricate the cutting position. In view of this, the applicant of the present invention invented a power tool holder with a simple structure, ingenious design, stable transmission and high-pressure central water outlet.

The water inlet module includes a water inlet hole, a turning channel, a connecting pipe, a housing cover and a water inlet block. The connecting pipe connects the turning channel and the water inlet block. The water inlet hole is communicated with the coolant outlet pipe of the tool turret. The coolant enters from the water inlet hole, flows through the turning channel and the connecting pipe into the water inlet block, and is sprayed out from the tool center spray hole through the channel in the center of the driven shaft.

[0007] Further, the driving gear, the transition gear and the driven gear are helical gears and are in the same horizontal position.

[0009] Further, the water inlet hole is arranged on the end face of the upper housing facing the tool turret installation, and the steering channel is arranged inside the upper housing and the lower housing.

[0010] Further, a detection hole is arranged on one side of the lower housing. The detection hole is communicated with the steering channel, and a plug block is arranged in the detection hole.

[0011] Further, the shell cover is fixed on the lower housing by bolts.

[0012] The beneficial effects of adopting the above technical solutions are as follows:

[0013] 1. By arranging a transmission mechanism and using helical gears as the driving gear, the intermediate gear and the driven gear, it has the advantages of high transmission efficiency, low noise, strong load capacity, high precision, etc.
