Abstract
A device for machining a milling groove in a hole comprises a gear shaft, a fastening bolt, a gear set, thrust bearings, a driving gear, a milling cutter, a thrust shaft and an extension rod. The device is characterized in that the thrust shaft is arranged in the middle of the extension rod. The thrust bearings are disposed on the thrust shaft and on two sides of the extension rod. The driving gear is arranged on the thrust shaft and in the middle of the extension rod. The gear shaft is disposed on the front end of the extension rod. The milling cutter is disposed on the axis of the gear shaft and is fixed on the gear shaft through the fastening bolt. The gear set is arranged between the gear shaft and the driving gear. The device has the advantages of adopting the method of transmitting power through multistep gears, being high in machining accuracy and suitable for machining grooves in the holes, and improving production efficiency of hydraulic motors.
