Description

Lathe cutter tower indexing means

Technical field

The utility model particularly relates to the lathe cutter tower indexing means of improvement about the lathe field.

Background technology

At present, at computer numerical control (CNC) lathe (Computer number control, be called for short CNC) wait and process machine knife tower structure part, owing to must earlier its capstan head of exerting oneself partly be locked in its operation, make it when carrying out operations such as turning, can resist the huge circumferential force moment of torsion that cutterhead produces, therefore, must be equipped with the latch-up structure of the capstan head of exerting oneself, the bent tooth-like clutch of existing at present use is as latch-up structure; And inputting shaft has seen at present that with the joggle piece of the capstan head of exerting oneself the plate cam of use or roller profile of tooth cam are arranged, and still, its assembly of this series products is various, the cost height, and noise in operating value height, and be easy to generate fault, obviously not ideal designs.

The utility model content

In view of this, main purpose of the present utility model be to provide a kind of cheap, noise is low, calibration is controlled accurate lathe cutter tower indexing means.

In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of lathe cutter tower indexing means, and it is provided with the main casing that can hold each member, and described member comprises:

Go into the power indexing means, the described power of going into indexing means is provided with the inputting shaft by the motor transmission, at the solid circular index member of the axle body string of described inputting shaft;

Force-output shaft, the front end of described force-output shaft pass described main casing and connect cutterhead;

The axle body end of described force-output shaft is combined with the capstan head of exerting oneself, and the described capstan head of exerting oneself is provided with most rollers;

Clutch positioner, described clutch positioner are provided with the bent tooth-like clutch of three-chip type, and the bent tooth-like clutch of described three-chip type includes anter, middle sheet and rear panel, wherein

Described anter is fixed in described main casing; The sheet string is tied the axle body in described force-output shaft in described; Described rear panel is incorporated into degree of tightness sheave front end face, and is through on the described force-output shaft, be located in described force-output shaft on described in sheet to be the bent flank of tooth relative;

Described degree of tightness sheave is incorporated into swing arm set, and the described swing arm set end that becomes the axle point is fixed in the described main casing with swing arm rotating shaft combination, and its arm body is promoted by the push rod with the hydraulic cylinder interlock;

Described circular index member is a barrel cam, and it has spiral helicine race according to the design of calibration stroke;

The described capstan head of exerting oneself of described force-output shaft walks in described race with the corresponding engagement of its most described rollers.

Beneficial effect after the employing technique scheme is: by the above-mentioned power of going into indexing means, make it reach effect and purposes such as cheap, that noise is low, calibration is accurate.

The specific embodiment

See also Fig. 1, be the perspective exploded view that the member of lathe cutter tower indexing means in the utility model is formed, it is to hold each member by main casing 1, and described member comprises:

Go into power indexing means 2, be provided with inputting shaft 20, at the solid circular index member 21 of axle body string, and circular index member 21 should be a kind of barrel cam, and it has spiral helicine race 210 according to the design of calibration stroke;

Inputting shaft 20 is by motor 22 transmissions;

Force-output shaft 3, its front end pass main casing 1 and connect cutterhead 5;
