Embodiment

[0023] 1. Complete computer modeling and generate NC machining program

[0024] Use the computer development language to develop the modeling program of the gear shaping cutter on the 486 computer and its compatible machine, input the basic parameter information such as the module of the gear shaping cutter, the number of teeth, the pressure angle, the rake face deformation coefficient, etc., and generate the applied negative chamfering The processed gear shaper cutter model is compiled on the CNC machining center to form a CNC machining program according to the generated model.

[0025] 2. Check the parallelism of the gear shaper cutter surface

[0026] Place the gear shaper cutter flat on the workbench with the rake facing upwards. Adhere the dial gauge to the spindle of the machine tool, move the spindle roughly to the center of the gear shaper cutter, and control the z-axis of the machine tool to drop until the contact of the gauge contacts the rake face. Rotate the spin...

Abstract

The invention relates to a machining method of a negative chamfer of a hard tooth-surface pinion cutter, comprising the following steps of: developing a modeling program of the hard tooth-surface pinion cutter by utilizing a computer development language so as to generate a pinion cutter model applied to the machining of the negative chamfer and generate a numerical control machining program of an involute chamfer of the hard tooth-surface pinion cutter in a numerical control machining center; automatically realizing the movement locus of the chamfer through the numerical control compensationfunction of the numerical control machining center, finishing the chamfers of the tooth sides and the tooth crests of all teeth in a one-pass way by adopting a diamond grinding tool, and continuouslyfinishing the machining of the chamfers. The negative chamfer of the hard tooth-surface pinion cutter, which is machined by adopting the method, has the advantages of ensuring the hard tooth-surface pinion cutter has high cutting edge strength, being difficult to crack a cutting edge, prolonging the service life of the hard tooth-surface pinion cutter, controlling an edge shape error, and the like.

Description

technical field [0001] The invention relates to a processing method for negative chamfering of a gear shaper cutter on a hard tooth surface, belonging to the field of tool processing. Background technique [0002] At present, the processing method of negative chamfering of gear shaping cutters for hard-toothed gears usually adopts: (1) flying knife chamfering method. For gear cutters, chamfer one side of the gear shaper cutter. (2) The automatic chamfering method of the disc grinding wheel, the grinding wheel is fixed so that in addition to rotating, it is also pressed against the tool floatingly according to a certain torque. When the tool rotates, due to the change of the radial grinding force, the grinding wheel shaft produces a certain amount. The degree of swing ensures that the grinding wheel contacts along the edge of the tool, and when the tool rotates a circle, the chamfering is completed. (3) The worm-type grinding wheel chamfering method uses the rotation of the...
