Abstract
The utility model discloses a milling cutter for processing spline shafts, relating to a milling cutter and used for solving the problems that no special cutter for processing spline shafts is arranged in the conventional machine tool equipment and the processing efficiency is low. The milling cutter for processing spline shafts comprises a cutter arbor, a blade, a nut and a connecting key, wherein the cross section of the cutter arbor is circular, a screw thread and a cylindrical boss are processed on the outer wall of the cutter arbor from front to back along the axial direction of the cutter arbor, a cutter-arbor key groove is processed on the side wall of the cutter arbor along the axial direction of the cutter arbor, a blade key groove is processed on the side wall of an inner hole of the blade, the blade is sleeved on the front end of the cutter arbor, the connecting key is respectively connected with the cutter-arbor key groove and the blade key groove, and the nut is connected with the screw thread so as to fasten the blade on the cutter arbor. The milling cutter disclosed by the utility model is a cutter for processing spline shafts.
Description
Technical field
The utility model relates to a kind of milling cutter, is specifically related to a kind of processing splined shaft and uses milling cutter.
Background technology
Because the processing splined shaft does not have the special molding cutter, normally programmes at CNC milling machine, processes with the mode of curved surface milling, each teeth groove of splined shaft can not process at one time, and working (machining) efficiency is low.
The utility model content
The purpose of the utility model provides a kind of processing splined shaft and uses milling cutter, and the processing splined shaft does not have the special molding cutter in the existing machine tool to solve, and each teeth groove of splined shaft can not process at one time, the problem that working (machining) efficiency is low.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: the described processing splined shaft of the utility model comprises knife bar, blade, nut and connecting key with milling cutter; The cross section of knife bar is circular; The outer wall upper edge knife bar axis direction of knife bar is processed with screw thread and cylindrical boss from front to back, and the sidewall upper edge knife bar axis direction of knife bar is processed with the knife bar keyway, is processed with the blade keyway on the endoporus sidewall of blade; Blade is sleeved on the front end of knife bar; Connecting key is connected with the blade keyway with the knife bar keyway respectively, nut be threaded, with blade tightly on knife bar.
The utlity model has following beneficial effect:
The described processing splined shaft of the utility model uses milling cutter to be fabricated construction, and the splined shaft of processing different size specification only need be changed the milling cutter of corresponding section shape size, and each teeth groove of splined shaft uses this cutter to process at one time.After tooth depth processes a teeth groove on request, rotate N time, accomplish the processing of all teeth groove of splined shaft by the number of teeth.The utility model use this dedicated tool to improve working (machining) efficiency, and machining accuracy also greatly improves for processing splined shaft dedicated tool.
