Abstract
The utility model relates to a spindle bar assembly for an air flotation high-speed electric spindle, particularly the spindle bar structural assembly for machining a high-speed spindle knife handle of a lathe. In the spindle bar assembly, at least one lubricating oil groove (6) is formed on the outer wall of a jacket (3) of a spindle bar main body. The friction between a spindle bar and a spindle core is reduced, so that the higher smoothness in the whole movement is achieved, the work efficiencies of an air cylinder and the spindle are improved, the service life of the spindle core is prolonged and the assembly precision can be ensured; and the spindle bar assembly is simple in machining, is convenient to mount and dismount a knife as well as popularize and apply and has high operation reliability.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically a kind of axle despot structure assembly that is used for mechanical processing machine high-speed main spindle handle of a knife.
Background technology
The axle of main shaft chuck is seized by force and is constructed, and is used for fixing the chuck afterbody, increases chuck stability, but because when the main shaft high speed rotating, axle is seized by force a meeting and an axle in-core wall friction, therefore a structure of seizing by force often has influence on the service life of a core.
Summary of the invention
The utility model relates to a kind of axle despot assembly of air floated high speed electric mandrel, it reduces the friction between axle despot and axle core, make whole motion more smooth and easy, improve cylinder and main shaft operating efficiency, the loading and unloading cutter is convenient, improves the axle core life-span, can guarantee assembly precision, processing is simple, and the operating reliability height is convenient to promote and use.
The utility model technical solution is at existing axle core (1), axle overlord's body (2), the axle external cover of overlord (3), butterfly spring (4), on the basis of chuck (5), the utility model particularly axle external cover of overlord (3) outer wall is provided with a minimum oil-way (6).
More than axle described in the utility model overlord's body (2) outer wall be provided with two oil-ways (6).
When the utility model is worked, axle overlord's body (2) is because cylinder action promotes compression butterfly spring (4) down, because axle overlord's body (2) is threaded with chuck (5), after butterfly spring (4) pressurized, the pulling force of chuck is laid down, chuck recovers outside tension force, can realize unloading the cutter function, after cylinder air pressure was laid down, butterfly spring (4) resetted chuck is held, this moment, chuck can be clamped cutter, had realized dress cutter function; The axle external cover of overlord (3) is a high-temperature resistance plastice spare, locates to increase oil-way (6) storage lubricating oil at the external cover of axle overlord (3) simultaneously, reduces friction as far as possible, makes whole motion more smooth and easy, improves cylinder and main shaft operating efficiency.
Advantage of the present utility model is:
1, the loading and unloading cutter is convenient, reduces friction as far as possible, makes whole motion more smooth and easy;
2, high efficiency improves the axle core life-span, can guarantee assembly precision;
3, processing is simple, the operating reliability height.

Fig. 2 is that axle overlord's body of the present utility model and axle overlord extracorporeal set are joined organigram.
Fig. 3 is an axle overlord body K of the present utility model place organigram.
The specific embodiment
According to Fig. 1, Fig. 2 and shown in Figure 3, the utility model is at existing axle core (1), axle overlord's body (2), the axle external cover of overlord (3), butterfly spring (4), on the basis of chuck (5), the axle external cover of overlord (3) outer wall is provided with a minimum oil-way (6).
Identical with embodiment 1, be that described axle overlord's body (2) outer wall is provided with two oil-ways (6).
Claims (2)
1. the axle of an air floated high speed electric mandrel is seized by force assembly, and it has comprised an axle core (1), axle overlord's body (2), the axle external cover of overlord (3), butterfly spring (4), chuck (5) is characterized in that the external cover of an overlord (3) outer wall is provided with a minimum oil-way (6).
2. the axle despot assembly of a kind of air floated high speed electric mandrel according to claim 1 is characterized in that overlord's body (2) outer wall is provided with two oil-ways (6).
