Problems solved by technology

The radial cutting method of the worm grinding wheel is to fix the grinding wheel and the gear shaper cutter at a relative position, and use a section of the circular arc surface of the grinding wheel to approximate the profile of the gear shaper cutter, but this method theoretically only has one section that can form an accurate The involute tooth profile, the machining accuracy is not high
The large surface grinding can guarantee high processing accuracy, but the single tooth is used to generate grinding one by one, which is inefficient and difficult to process some specific tooth top and root chamfers

Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] Use the conical worm grinding wheel to diagonally generate the finishing gear shaping tool method, which is used for grinding the conical worm grinding wheel of the gear shaping tool. The taper of the worm grinding wheel is used to increase the meshing of the grinding wheel and the gear shaping tool Increase the degree of coincidence, increase the length of the meshing line between the grinding wheel and the gear shaper cutter, give full play to the advantages of high precision and high efficiency of the worm grinding wheel generating grinding, improve the processing efficiency of the gear shaper cutter, and reduce the processing cost. The movement process of gear shaping cutter processed by conical worm grinding wheel is similar to cylindrical worm grinding wheel grinding, and the schematic diagram of gear shaping cutter grindi...

Abstract

The invention belongs to the field of manufacturing of gear cutters, and relates to a method for finishing a gear shaper cutter by the diagonal contour evolution of a conical worm grinding wheel. The worm grinding wheel is trimmed to be conical along the rotating axis of the worm grinding wheel, the gear shaper cutter is machined by adopting a diagonal contour evolution process, and the grinding wheel is also required to move along the radial direction of the gear shaper cutter in a machining process, so that the worm grinding wheel can be ensured to be approximately equivalent to a standard rack at different moments, and a gear shaper cutter capable of meeting an accuracy requirement can be machined.

Description

technical field [0001] The invention belongs to the field of manufacturing gear cutters, in particular to the field of manufacturing gear shaping cutters, and relates to a method for diagonally generating and finishing gear shaping cutters using a conical worm grinding wheel. Background technique [0002] The gear shaper cutter is one of the most widely used tools in gear machining. Its shape is like a gear, with its rake angle and back angle forming the cutting edge, and the gear is inserted by the generating principle. The characteristic of the gear shaper cutter is that it can process gears with shoulders, multi-connected gears and herringbone gears without empty grooves. Gear shaper cutters with different structures can process different gears, which can be divided into disc shape, bowl shape, cylindrical shape and tapered shank gear shaper cutters according to their shape. Since both the top edge and the side edge of the gear shaper cutter have relief angles, the size ...
