Abstract

The invention discloses a knurl aligning device for a shaft. The knurl aligning device for the shaft comprises a pair of positive tool arm and negative tool arm which are arranged opposite to each other and a tool arm supporting sliding plate used for connecting the positive tool arm and the negative tool arm, wherein knurl wheels are arranged at one ends of the positive tool arm and the negative tool arm respectively; and the other ends of the positive tool arm and the negative tool arm are arranged on the tool arm supporting sliding plate. The knurl aligning device for the shaft is characterized by also comprising a bracket used for connecting the tool arm supporting sliding plate and a processing machine, a positioning core shaft and spring leaves, wherein through holes are correspondingly formed in the tool arm supporting sliding plate and the bracket respectively; the positioning core shaft penetrates through the through holes of the supporting sliding plate and the bracket; the spring leaves are arranged on the two sides of the bracket respectively; one ends of the leaf springs are fixed to the bracket; the other ends of the leaf springs are abutted to the side part of the tool arm supporting sliding plate; and two spring leaves limit rotation of the tool arm supporting sliding plate with the positioning core shaft as the center. The invention provides the knurl aligning device for the shaft, which can realize self-centering and improve the processing efficiency and accuracy of a shaft spline.

Description

technical field [0001] The invention relates to a positioning alignment device, in particular to a shaft knurling alignment device. Background technique [0002] For a splined connection, one end of the shaft needs to be knurled, such as the drive shaft found in a vehicle fan clutch. For example, the Chinese invention patent with the existing publication number 204799979U discloses "A Kind of Knurled Knife", which includes a base, a knife arm, a locking device and a knurled knife, and is characterized in that two sides of the top of the base are hinged. Knife arm, the free end of the knife arm is hinged with a knurling knife, the middle part of the knife arm is provided with a guide hole, the guide rail arranged on the base passes through the guide hole, and the guide hole is also provided with two knife arms Fixed locking device. However, the knurling cutter needs to manually adjust the center height between the knurling cutter and the axis of the machining shaft during t...
