[0004] The tools used in the above-mentioned various gear processing processes, except for tooth milling and form grinding, which are based on the profiling principle, and a tool can only process gears with specific geometric parameters, other processes are based on the generative method The process of cutting teeth with gear-shaped tools, although the geometric structure of the tools used in various processes and the relative movement between the tool and the workpiece during processing are different, the same modulus of tools can process gears with different numbers of teeth, different diameters and different helix angles Workpieces, but different processes require different equipment
The flow of workpieces between devices, on the one hand, makes the production line longer and lowers processing efficiency; on the other hand, workpieces need to be positioned and clamped repeatedly, which will inevitably lead to repeated positioning errors, and the geometric errors of tools used in different processes are different. In the end, it will be mapped to the geometric error of the workpiece, which directly affects the machining accuracy of the gear.

[0051] Please refer to figure 2 , the present embodiment provides a turning, shaving and honing compound gear processing tool (hereinafter referred to as the gear processing tool 200), on the basis of the first embodiment above, the structure of the handle 4 is a Morse taper shank.
[0052] It should be noted that Morse taper is an international standard for taper, which is used for static fit for precise positioning. Because the taper is very small, a certain torque can be transmitted by using the principle of friction, and because of the taper fit, it can be easily disassembled. Within a certain range of the same taper, the workpiece can be disassembled and assembled freely, and at the same time it will not affect the use effect during work. For example, if the taper shank drill for drilling holes needs to be disassembled for grinding during use, it will not be necessary to reinstall it after disassembly. Affects the center position of the drill.

Description
technical field [0001] The invention relates to the field of gear processing devices, in particular to a gear processing tool combined with turning, shaving and honing. Background technique [0002] Gears are important basic parts for mechanical transmission, and improving gear machining efficiency and machining accuracy has always been the focus of the gear manufacturing industry. [0003] The gear machining process is mainly rough machining→semi-finishing→finishing. At present, the gear roughing process includes the widely used processes such as gear hobbing, gear shaping, and milling, as well as the rapid development of gear turning process in recent years; the semi-finishing process includes fine hobbing, fine gear shaping, gear shaving, etc.; finishing The process includes gear honing (such as free honing, powerful honing), gear grinding (such as profile grinding, worm wheel grinding, large plane gear grinding, etc.). [0004] The tools used in the above-mentioned var...
