Abstract

The invention provides a gear hobbing universal fixture. The gear hobbing universal fixture comprises a base, a positioning shaft, a supporting piece, a positioning sleeve and a fastener, wherein thelower end of the positioning shaft is fixed to the base through the fastener; the supporting piece is arranged above the base; the fastener is arranged at the upper end of the positioning shaft; a workpiece clamping area is arranged between the fastener at the upper end of the positioning shaft and the supporting piece; and the positioning sleeve sleeves a positioning shaft section of the workpiece clamping area. Through the gear hobbing universal fixture, clamping and positioning during gear machining can be rapidly carried out, clamping and positioning standards are unified, clamping and alignment time during product machining is reduced, and machining precision of products is improved. In the gear machining process with different positioning sizes, the machining and positioning of different products is realized by adjusting the height of the supporting piece and the outer diameter of the positioning sleeve, the tool investment cost of the products in the machining process is reduced, the clamping efficiency, the accuracy and the machining efficiency are improved, and obvious economic benefits are created.

Description

technical field [0001] The invention relates to the field of gear processing, in particular to a universal jig for gear hobbing. Background technique [0002] When processing hobbing gears, the workpiece to be processed needs to be fixed on the machine table. One of the existing fixing methods is to clamp the workpiece to be processed in the fixture, and fix the fixture on the processing machine. The usual fixture is customized according to the parts, and it is only suitable for clamping gear parts of one size; the other is The fixing method is to fix the workpiece through the three-grip chuck. Every time the workpiece is changed, it needs to be aligned once, which cannot guarantee the consistency of processing and positioning. This kind of gear parts has a wide variety of models, different positioning sizes, large investment in fixtures, long time for repeated measurement and alignment during mass production, poor machining accuracy, and low production and processing effic...
