Abstract
The utility model relates to a mechanical processing technique, more specifically a special tool for drilling of a cross universal joint, which comprises a tool shank and a tool edge. The utility model is characterized in that the tool edge part is provided with back angles and side edge back angles, and the inner part of the tool shank is provided with a chip containing hole. The utility model is exclusively used for a cross universal joint, and the inner part of a machining hole of the cross universal joint is provided with a core. The number of teeth of the tool edge can be one or more, and the tool has sufficient back angles and side edge back angles. The utility model has the advantages of smooth chip removal, not easy abrasion of the tool, high machining speed, good quality, simple structure and convenient machining.
Description
One, technical field
The utility model belongs to the machining class, specifically is a kind of candan universal joint boring dedicated tool.
Two, background technology
When processing on the candan universal joint hole according to actual needs, must leave stamen in the hole, at present, multiple cutter has been used in each manufacturer's design, but all have following defective: (one) makes cutter in use very easily collapse the fracture of cutter even cutter hub because chip removal is not smooth; (2) because cutter does not have relief angle and side edge relief angle, cutter is is very easily worn and torn, reduce service life; (3) can't process the excessive circular arc of actual needs.
Three, technology contents
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of and can satisfy processing request, reliable quality candan universal joint boring dedicated tool.
The technical solution of the utility model is as follows:
A kind of candan universal joint boring dedicated tool comprises handle of a knife, blade, and it is characterized in that: knife edge part has relief angle and side edge relief angle, has one to hold the bits hole in handle of a knife.
Have the tip relief sword on the blade of the present utility model, be used for the tip relief of workpiece in case of necessity.
Blade of the present utility model can be one or more.
The utility model is under the prerequisite that guarantees cutter intensity, and mill has enough relief angles and side edge relief angle, makes cutter sharp, improves the workpiece process velocity; And the contact area of minimizing workpiece and cutter, make cutter not easy to wear, improve service life; And can reduce the blade number, and make cutter when work, enough chip spaces be arranged, chip removal is smooth and easy.The utility model is simple in structure, easy to process, can manufacture workpiece.
