Description
The application relates to a Chinese patent application of a compound cutter for chamfering and rolling gears, which is filed on the application date 2018, 06 and 05 and has the application number 201810567304.4.
Technical Field
The invention relates to the technical field of gear end face chamfering tools, in particular to a composite cutter for gear chamfering and rolling, and a gear chamfering and rolling method.
Background
In the gear machining process, particularly after the gear hobbing process, burrs and burrs are very easy to generate on edges of two end faces of the tooth profile of the gear, and the subsequent finishing shaving or gear grinding and honing process can be influenced. Meanwhile, noise of gear engagement can be caused by the existence of burrs on edges of two end faces of the gear, and therefore the performance of the equipment is affected. For this purpose, deburring of the edges of the two end faces of the gear wheel after the hobbing is generally required.
At present, there are two general methods for deburring edges of two end surfaces of a gear:
Firstly, adopt the manual method burring, its machining efficiency is lower, and the quality of burring is unstable.
Secondly, adopt the chamfer sword, place the gear on the chamfer lathe, carry out mechanical automation chamfer (chamfer sword is as the action wheel, drives the gear meshing and rotates and realize the chamfer), its production efficiency is higher. The typical chamfering tool is a meshing extrusion chamfering tool, which adopts a full tooth profile chamfering method, two disc type chamfering tools are symmetrically arranged at two end surfaces of a gear, and a tooth top relief angle and a tooth side relief angle are arranged on the chamfering tools. In the working process, a radial acting force is applied by a machine tool, so that meshing rotation and extrusion are formed between the chamfering tool and the gear, a certain chamfer is extruded by a rear tool face on the chamfering tool at the edge of the end face of the gear, and the chamfer angle is determined by the rear angle of a tooth top of a cutter tooth and the rear angle of a tooth side of the chamfering tool.
In the prior art, the chamfering of gears by adopting the chamfering cutter has the following problems: after the tooth surface of the gear is extruded by the chamfering knife, flanging can be generated on two end surfaces of the gear, tiny bulges can be generated on the tooth profile surface of the gear, and the height is generally 0.05-0.2 mm. Usually flanging of both end faces of the gear can be solved by installing a scraper in a chamfering machine. However, the tiny protrusions on the tooth profile surface of the gear can influence the subsequent finishing shaving or gear grinding and honing procedures. To solve this problem, two measures are generally taken to protect: one is to add a rolling procedure, and the tooth surface bulge is pressed down to be within 0.02mm by a rolling wheel; the other is to add a fine rolling process to remove the protrusions of the tooth surface by hob cutting, however, these added processes inevitably reduce the production efficiency and increase the manufacturing cost.
In order to solve the above problems, a composite tool for chamfering and rolling is required to be developed. The Chinese patent with the issued publication number of CN202943336U discloses an integral rolling chamfering compound cutter, wherein a group of chamfering teeth and a group of rolling teeth are respectively arranged on a disc-shaped cutter disc, and the chamfering teeth and the rolling teeth occupy half discs respectively, and the upper half disc is used for chamfering and the lower half disc is used for rolling, so that rolling chamfering compound processing is realized.
However, in order to respectively finish rolling and chamfering all teeth of a circle of gears, the total number of teeth on a cutter disc of the rolling and chamfering composite cutter adopting the patent needs to be twice as large as the number of teeth of the gears, so that the cutter disc is larger in size, the cost of the cutter is increased, and the stability of the cutter disc with larger size is reduced during rolling and chamfering, so that the processing quality is reduced. In addition, the structure that chamfer teeth and rolling teeth occupy half of the disc is adopted, and the defect of large unbalance of the cutter disc is also caused.
