Specific implementation mode
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant to the invention.
As Figure 2-3, a kind of interrupted end face annular knurl or hobbing device, including roll cone pulley 1, cone pulley axis 2 and driving dress
It sets, the cone pulley axis 2 is threaded through 1 center of cone pulley that rolls, and the rolling cone pulley 1 is rotated around the cone pulley axis 2.
The driving device includes the work for driving workpiece to be processed 5 to be rotated around the rotation axis 52 of workpiece to be processed 5
Part drive component and/or for drive it is described rolling cone pulley 1 around workpiece to be processed 5 rotation axis 52 revolve round the sun cone pulley driving group
Part, you can roll cone pulley 1 around itself axis to rotate and drive around the rotation axis 52 of workpiece to be processed 5 by workpiece to be processed 5
Line (i.e. the central axis 21 of cone pulley axis 2) rotation, or roll cone pulley 1 and revolve round the sun and drive rolling cone pulley 1 around 5 rotation axis 52 of workpiece
The rolling rolling of 5 end tooth of workpiece to be processed is realized around own axes rotation.End face of the cone pulley axis 2 with respect to workpiece to be processed 5
51 tilt.
1 surface of rolling cone pulley is hobboing cutter 11, and the hobboing cutter 11 has gear hobbing or annular knurl, when processing, rolls cone pulley 1
Rolling forms double wedge 53 in 5 end face 51 of workpiece to be processed for gear hobbing or annular knurl.
Further include for the fixed knife bar 3 and bearing 4 for rolling cone pulley 1, the rolling cone pulley 1 by cone pulley axis 2 with it is described
Knife bar 3 is fixedly connected, and the bearing 4 is set in outside cone pulley axis 2, is rolled cone pulley 1 and is rotatablely connected with cone pulley axis 2.The bearing 4 is
Needle roller thrust bearing.
In order to ensure that rolling process realizes pure rolling, the rotation axis of the central axis 21 and workpiece to be processed 5 of cone pulley axis 2
52 intersections, and intersection point A is overlapped or is substantially overlapped with the rolling circle center point B of 5 end face 51 of workpiece to be processed.Because of installation error,
Actual processing process A points can be located near B points.
As shown in Fig. 1, Fig. 4-5, there is discontinuous slit 54, hobboing cutter radius R to meet following public on 5 end face 51 of workpiece to be processed
