Utility model content
The utility model provides a kind of internal gear tooth inserting tooling, to solve above-mentioned deficiency.Use axle to coordinate spring expanding sleeve and internal spline to carry out pitch circle location, with accurate centering spline endoporus, thus ensure internal spline and internal gear pitch circle axiality; And by the seamless connectivity of spring expanding sleeve and internal spline, to ensure radial location precision, and because not needing to clamp thin-walled portion, thus reducing workpiece deformation, ensureing gear shaping precision; Use whirligig rotational workpieces, quick, convenient tool setting can not only be realized, and axial location can be carried out further, to reduce position error; Dust excluding plate can keep internal spline surface cleaning, reduces operation, reduces processing consuming time, ensures reorientation precision.In sum, the utility model clamps stable, registration, tool setting is easy, thus reduces labour intensity, and can ensure Workpiece Machining Accuracy, products quality guarantee, enhances productivity.
In order to realize the purpose of this utility model, intend adopting following technology:
A kind of internal gear tooth inserting tooling, is characterized in that: comprise clamp body, axle, spring expanding sleeve, whirligig, tool setting device and dust excluding plate; Described mandrel bottom is installed in described clamp body central channel; Described spring expanding sleeve is set in described mandrel outer downwards from described axle top; Described whirligig is set in described mandrel outer, and is fixed on described clamp body; Described tool setting device is fixed on described clamp body outer wall; Described dust excluding plate is covered on described spring expanding sleeve.
Further, described whirligig comprises kerve, rebound, annulus and spill spin block, and described spill spin block is arranged at described kerve groove along inwall, and described annulus is arranged between described spill spin block and described rebound,
Further, in the described kerve below described annulus, be provided with box spanner,
Further, clamp nut is provided with between described spring expanding sleeve and described axle.
The beneficial effects of the utility model are:
1. adopt internal spline expansion set pitch circle location, to workpiece without initial required precision, internal spline and internal gear pitch circle axiality can be ensured, and repetitive positioning accuracy is high.
2. be provided with whirligig, workpiece can not only be realized and rotate tool setting, and not need to clamp workpiece thinner wall section, reduce workpiece deformation, to ensure inside and outside gear individual event precision, further stabilized product quality.
3. dust excluding plate can prevent iron filings or cooling fluid from entering in expansion set pitch circle location structure, and to reduce operation, minimizing processing is consuming time, and ensures reorientation precision.
