A kind of gear shapping machine provided by the invention quantitatively regulates the device of relieving amount, by increasing position-arresting disk and outer back-up ring, coordinate special alignment pin, to regulate the thickness of position-arresting disk and outer back-up ring accurately to control cutter relieving adjustment amount in production, thus effectively can avoid the problem cannot adjusting to suitable relieving amount because operator lacks experience, namely associative operation no longer relies on the working experience of operating personnel, thus improves the quality of production and working (machining) efficiency.It is simple that the present invention has structure, easy to use, quantitatively advantage accurately.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the main TV structure schematic diagram of apparatus of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to generalized section.
In figure: column 1, alignment pin 2, the first disc spring 3, alignment pin threaded portion 4, thread bush 5, position-arresting disk 6, spacing back-up ring 7, second disc spring 8, adjusting knob 9, tool-post structure 10, connecting portion 11, stifled post 12.
Detailed description of the invention
As in Fig. 1, a kind of gear shapping machine quantitatively regulates the device of relieving amount, comprise tool-post structure 10, tool-post structure 10 is supported on column 1 by stifled post 12, as in Fig. 2, tool-post structure 10 is also provided with tow-way tool retracting device, and in described tow-way tool retracting device, alignment pin 2 is provided with the alignment pin threaded portion 4 being positioned at middle part and the bearing pin portion being positioned at two ends; The axis of described alignment pin 2 and the projection of axis on vertical perspective plane of tool-post structure 10 orthogonal.
As in Fig. 2, in tool-post structure 10 both sides, alignment pin threaded portion 4 forms threaded engagement with the thread bush 5 fixedly mounted on tool-post structure 10 by screw thread, the outer end of alignment pin threaded portion 4 is provided with the position-arresting disk 6 limiting alignment pin 2 axial location, is positioned at the spacing back-up ring 7 be also provided with outside tool-post structure 10 for limiting alignment pin 2 axial location.Pin-and-hole on the bearing pin portion of alignment pin 2 and column 1 is formed and is slidably matched, the bearing pin portion at two ends is separately installed with the first disc spring 3 and the second disc spring 8, each disc spring act as pressurized after utilize the elastic force of reply to make this end away from column 1, thus tool-post structure 10 slightly rotates for the center of circle with stifled post 12, realizes the cutter relieving of tool-post structure 10.
