Description

Gear hobbing frock

Technical Field

The utility model relates to a tool, in particular to a gear hobbing tool.

Background

The gear hobbing tool is used for fixing parts needing to be machined. Chinese utility model patent with publication number CN203371133U discloses a hobbing frock of shaft gear includes: the lathe body, interior conical positioning seat, the lower centre mechanism, the upper centre of establishing the shoulder hole, the conical positioning seat rigid coupling of establishing the shoulder hole is in establishing the shoulder hole in the conical positioning seat of shoulder hole on the lathe body, lower centre mechanism sets up in establishing the shoulder hole in the conical positioning seat of shoulder hole, the upper centre with the lower centre mechanism is with the axle center cooperation setting, the conical surface point is relative.

However, because the height of the machine tool body and the positioning seat is limited, when the tool is used for processing a hobbing product which can not turn around, the hobbing length can only be within 300mm, after the hobbing length exceeds 300mm, the hobbing cutter reaches the limit of equipment, the product can not be processed, and if the product is processed, equipment needs to be purchased again or procedures need to be added.

Disclosure of Invention

The utility model aims to solve the technical problem that the length of the existing hobbing tool for machining hobbing is limited, and provides a hobbing tool which can machine the length of the hobbing tool exceeding 300 mm.

Therefore, the utility model provides a gear hobbing tool which is provided with a positioning seat and a jacking device, wherein a positioning hole is formed in the positioning seat, the positioning seat is provided with a positioning disc and a positioning shaft, the positioning disc divides the positioning shaft into an upper positioning shaft and a lower positioning shaft, the height of the upper positioning shaft is 25-30 cm, and the height of the lower positioning shaft is 95-100 cm.

Preferably, the height of the upper positioning shaft is 28.87cm, and the height of the lower positioning shaft is 96.1 cm.

Preferably, the jacking device is provided with a lower tip and an upper tip, and the lower tip is arranged in the positioning hole.

Preferably, a screw is arranged on the side face of the positioning plate and used for moving the hobbing tool.

Preferably, the positioning disc is further provided with a fixing hole, and the fixing hole is used for fixing the positioning seat.

Preferably, the positioning disc is further provided with a tip hole, and the tip hole is used for aligning the workpiece.

The utility model has the following beneficial effects:

the height of the tool positioning base is shortened, so that the relative length of the workpiece hobbing is reduced, the condition that equipment is not compatible with products in the machining process is solved, the normal machining of the products is further ensured, the process and size requirements are met, unnecessary equipment purchase or procedure increase is reduced, the efficiency is improved, and meanwhile, the production cost is reduced.
