Description

Disk six-hole ball-cage constant velocity universal joint shell impewdance matching frock

Technical field

This utility model relates to disk six-hole ball-cage constant velocity universal joint shell processing tool field, specifically a kind of disk Six-hole ball-cage constant velocity universal joint shell impewdance matching frock.

Background technology

The isogonism speed that constant velocity cardan joint keeps out-of-alignment two to connect shaft angle owing to it is distinctive transmits the work of torque With, it is provided simultaneously with compact conformation, transmission moment and efficiently and there is scalable sliding freely adapts to two axial ends apart from the requirement changed, Therefore in automobile driving axle, obtain popularization use.And disk six-hole ball-cage constant velocity universal joint is normal tape splined shank portion ten thousand To a kind of variant of joint, flimsy integrated disc portions as non-replaceable part, and can be separated by its splined shank portion because being hardly damaged, Also it is more suitable for intermediate propeller shaft simultaneously and more non-vehicle kind equipment uses.And disk six-hole crossed grooves sliding constant velocity cardan joint In addition to there are all functions of common sliding constant velocity cardan joint, also have that resistance to shock is good, bearing capacity big and vehicle connected mode The feature such as various, in addition to being applied in automobile driving axle, in other heavy duty equipment, Weaving device, printing equipment The most more and more used.But on the inner circular cylinder that it has distribution six grooves due to be two adjacent grooves be in intersection Shape, and six bolts hole are distributed simultaneously, the wall thickness local that therefore inner pitch between hole and groove is formed can be the thinnest, causes Can bore motionless during boring or drilling efficiency is low, bit damage is many phenomenon after inner chamber and six grooves make mid-frequency induction hardening； But if remaking inner chamber and the mid-frequency induction hardening of six grooves after Zuan Kong, then can produce the position formation in hole and cell wall thickness Crackle, therefore must assure that while mid-frequency induction hardening carrying out lasting cooling inside six holes, does not make its temperature obtain Rise, thus reach to prevent crackle from producing the purpose at bore edges.

Utility model content

The purpose of this utility model is to provide a kind of disk six-hole ball-cage constant velocity universal joint shell impewdance matching frock, comes Overcome existing mid-frequency induction hardening can cause the defect that six holes of workpiece crack with the edge of arc groove handing-over, pass through Hole wall constant temperature is made to be in structural transformation temperature to continual applying pressure is cooling water circulation inside six holes of workpiece Hereinafter, the mid-frequency induction hardening heating-up temperature of six arc grooves of workpiece lumen is unaffected simultaneously, it is ensured that bore edges does not produce and splits The phenomenon that stricture of vagina and stress are concentrated, can free mid-frequency induction hardening reach institute such that it is able to reach inner chamber sphere and six arc grooves The case depth needed and the technology requirement of case hardness.

The technical solution of the utility model is as follows:

A kind of disk six-hole ball-cage constant velocity universal joint shell impewdance matching frock, includes base and seal disc, and it is special Levying and be: the bottom of described base has the staight shank being connected installation with quenching machine, described seal disc is fixedly mounted on described On base, and on base, lower section at described seal disc is provided with cavity, is provided with and is connected with described cavity in described staight shank Through hole, described seal disc is provided with the counterbore for positioning workpiece, and the surrounding around described counterbore has been respectively fixedly connected with many Individual water jet column, is respectively equipped with the blind hole being connected with described cavity, the medial wall of multiple water jet columns in described multiple water jet columns On be respectively equipped with hole for water spraying that is densely covered and that be connected with described blind hole.

Described disk six-hole ball-cage constant velocity universal joint shell impewdance matching frock, it is characterised in that: described base Surrounding is respectively equipped with multiple screwed hole, and it is multiple that the surrounding of described seal disc is respectively equipped with the plurality of screwed hole corresponding matching Bolt hole, has multiple bolt to be screwed on respectively in corresponding bolt hole and screwed hole, is securedly mounted to by described seal disc On described base.

Described disk six-hole ball-cage constant velocity universal joint shell impewdance matching frock, it is characterised in that: described base with It is provided with sealing gasket between the faying face of described seal disc.

The beneficial effects of the utility model:

1, this utility model can reach effectively to cool down the hole wall in six holes of workpiece, reduce the purpose of temperature；

2, this utility model ensure that workpiece when mid-frequency induction hardening the edge in its six holes not because of inner chamber and six The high temperature penetration of groove and crack；

3, this utility model ensure that the inner chamber of workpiece and the depth of hardening zone of six grooves reach valid interval；

4, this utility model can ensure hole wall and water jet column gap uniform in six holes of workpiece by self-centering；

5, this utility model ensure that suffered by six holes of workpiece, cooling water pressure is uniform, and the suffered water yield is uniform.
