Technical Field

The invention belongs to the technical field of machining, and particularly relates to an automatic cleaning broach guide sleeve structure for gear machining.

Background

The gear is the most extensive and most important transmission part in the mechanical transmission, and the gear is generally connected with the transmission shaft through a key connection mode when being installed, and in the gear machining process, a broaching machine is generally adopted to machine the key groove, and in the broaching machine machining process, the guide sleeve is generally adopted to guide, so that the broach can normally slide left and right.

Based on the above, current broach guide pin bushing in use generally only has the direction function, and in use can have iron fillings to adhere on the broach after the broach accomplishes the broaching processing of a set of keyway, when adding man-hour the easy situation that presss from both sides the sword that appears once more, influences surface quality and processingquality, causes the broach damage even, and in use needs to clean iron fillings by hand.
