Abstract

The utility model discloses an inner tailstock gas sealing device which comprises a pneumatic FRL, a pipeline, a magnetic exchange valve, a pipeline connector, a sealing flange, a top-sharp rotating assembly, a sleeve and a tailstock body. The tailstock body is installed on a machine tool, the sleeve is installed inside the tailstock body, the top-sharp rotating assembly is installed inside the sleeve, the sealing flange is installed on the end face of the sleeve to fix the axial movement of the top-sharp rotating assembly, a gap is reserved between the top-sharp rotating assembly and the sealing flange, and the pipeline connector is installed on the sealing flange. The pneumatic FRL, the magnetic exchange valve and the sealing flange are connected through the pipeline in series. The inner tailstock gas sealing device is simple in structure and reliable in sealing, and can be widely applied to the numerical control machine tool. The probability that the tailstock body is damaged because sealing is unreliable can be effectively reduced.

Description

A kind of built-in tailstock gas sealing mechanism
Technical field
The utility model relates to a kind of numerical control machine tool device, specifically built-in tailstock gas sealing mechanism.
Background technique
In the numerical control machine tool industry, built-in tailstock uses extensively, and the tailstock seal form of this kind of form mainly contains labyrinth sealing and oil sealing sealing.Adopt labyrinth sealing, because there is gap in this kind of seal form, in course of working, water and dust enter bearing by gap, easily cause bearing damage; Adopt oil sealing sealing, during the tailstock center High Rotation Speed, oil sealing contacts with revolving part, produces a large amount of heat, easily causes tailstock to damage.
The model utility content
The purpose of this utility model is the deficiency existed for prior art, and a kind of gas sealing mechanism is provided, and it is simple in structure, good sealing effect, easy to use.
For realizing above-mentioned model utility purpose, the technical solution adopted in the utility model is a kind of built-in tailstock gas sealing mechanism, comprises pneumatic triple piece, pipeline, solenoid directional control valve, pipe joint, sealing flange, top swivel assembly, sleeve and tailstock body; Tailstock body is arranged on lathe, and sleeve is arranged in tailstock body, and top swivel assembly is arranged in sleeve, sealing flange is arranged on sleeve end face, the axial motion of fixed center swivel assembly, leave gap between top swivel assembly and sealing flange, and pipe joint is arranged on sealing flange; Pneumatic triple piece, solenoid directional control valve and sealing flange are connected by pipeline.
Described pneumatic triple piece comprises interconnective filter, reduction valve and oil sprayer.
Described pneumatic triple piece and solenoid directional control valve are arranged on lathe.
Be provided with pore in described sealing flange.
Leave uniform gap between described top swivel assembly and sealing flange.
Beneficial effect: the gas sealing mechanism that the utility model provides, simple in structure, sealing is reliable, can be widely used on numerical control machine tool, can effectively reduce the tailstock caused because sealing is unreliable and damage.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, the present embodiment is implemented take technical solutions of the utility model under prerequisite, should understand these embodiments and only for the utility model is described, be not used in restriction scope of the present utility model.
As shown in Figure 1, a kind of built-in tailstock gas sealing mechanism, comprise pneumatic triple piece (by filter, reduction valve, oil sprayer, interconnected and formed) 1, pipeline 2, solenoid directional control valve 3, pipe joint 4, sealing flange 5, top swivel assembly 6, sleeve 7, tailstock body 8.Tailstock body 8 is arranged on lathe, sleeve 7 is arranged in tailstock body 8, and top swivel assembly 6 is arranged in sleeve 7, and sealing flange 5 is arranged on sleeve 7 end faces, the axial motion of fixed center swivel assembly 6, leave uniform gap between top swivel assembly 6 and sealing flange 5.Pneumatic triple piece 1, solenoid directional control valve 3 is arranged on lathe, and pipe joint is arranged on sealing flange 5, in sealing flange 5, is provided with pore, and pipeline 2 is connected in series pneumatic triple piece 1, solenoid directional control valve 3, sealing flange 5.
During work, top swivel assembly 6 rotates with Work piece high-speed, pressurized air filters through pneumatic triple piece, pressurized air after filtration is through the break-make of solenoid directional control valve 3(pilot line), pipeline 2, pipe joint 4 enter in sealing flange 5, the pressurized air entered in sealing flange 5 outwards blows out via the gap between sealing flange 5 and top swivel assembly 6, the purpose that enters bearing to reach the foreign matters such as anti-sealing and dust.
