Abstract

The invention discloses a fixture for milling a spline shaft. The fixture comprises a front tip and a rear tip, wherein the front tip is abutted against the front end of the spline shaft, the rear tip is abutted against the rear end of the spline shaft, and the outer wall of the rear tip is provided with a sliding groove; the fixture also comprises a compressing sleeve and a threaded sleeve, wherein the compressing sleeve is arranged on the outer wall of the rear tip in a sleeving manner and connected to the rear top by a flat key, the flat key is positioned in the sliding groove, the front end of the compressing sleeve is abutted against the rear end of the spline shaft, the threaded sleeve is arranged on the outer wall of the rear tip in a sleeving manner and in threaded connection with the rear tip, the threaded sleeve is positioned behind the compressing sleeve, and a compressed spring is also arranged between the threaded sleeve and the compressing sleeve and abutted against both the threaded sleeve and the compressing sleeve. The invention, overcoming the technical defect that the existing fixture for milling the spline shaft is low in machining efficiency and precision, provides the fixture for milling the spline shaft, which is high in machining efficiency and precision.

Description

technical field [0001] The invention belongs to the field of machining fixtures, in particular to a fixture for milling a spline shaft. Background technique [0002] Spline shafts are usually used in factories for mechanical torque transmission. The spline shaft transmission is a kind of mechanical transmission. There are longitudinal key teeth on the surface of the spline shaft, and the rotating part set on the spline shaft has a key groove matching the key teeth, so that the rotation of the spline shaft can drive the rotating part to move forward. rotate. The splines on the spline shaft are usually milled on a spline milling machine, but currently there is no special fixture for spline milling, and people usually use jaws to clamp the end of the spline shaft when milling splines. , so as to position the spline shaft, but because the length of the optical axis at both ends of the spline is too short, if the jaws only clamp the optical axis, it will inevitably be unstable,...
