Description
Technical field
The utility model relates to electrocardio main shaft field in the machining, especially relates to a kind of electric sealing of spindles device.
Background technique
The electrocardio main shaft is the very high electromechanical integrated product of a kind of technology content in the machining.High-speed electric main shaft needs workpiece is advanced cooling with cutting fluid in course of working, and the flying to be stained with and to wash away of cutting fluid is easy to enter electric main shaft inside, and electric main shaft internal bearings and stator are caused damage.So sealability of electric front-end of spindle.Directly have influence on the working life of electric main shaft, as adopt the contact seal circle to seal, in the high speed rotary course of electricity main shaft, can work between can't be often because friction produces high temperature, adopt contactless labyrinth seal, can be because there being the gap between the labyrinth seal, produce seepage in the work and influence sealing effect.
Summary of the invention:
The purpose of this utility model provides a kind of rational in infrastructure, and sealability is reliable, can improve the electric sealing of spindles device in working life.
The utility model is achieved in that a kind of electric sealing of spindles device, comprises stator, preceding sealing cover, shell, and it is characterized in that: described stator is provided with preceding sealing cover, and preceding sealing cover and stator pass through scyewed joint; The shell side is provided with protecgulum, on the protecgulum on annular groove A and the preceding sealing cover annular boss B be fastened togather, on the protecgulum on annular boss A and the preceding sealing cover annular groove B be fastened togather and constitute contactless labyrinth seal.
The inboard cylindrical of sealing cover is provided with chamfering before described in the utility model.
Two sealing surfaces of protecgulum described in the utility model are provided with the pore that communicates.
Shell described in the utility model is provided with the sealing gland entrance, and the sealing gland entrance communicates with pore on the protecgulum.
The sealing cover exterior edge face exceeds the protecgulum exterior edge face before described in the utility model.
The utility model is rational in infrastructure, and sealability is reliable, has improved working life.
Description of drawings

Fig. 3 is the structural representation of preceding sealing cover in the utility model;
Among the figure 1, stator, 2, bearing, 3, the sealing gland entrance, 4, protecgulum, 401, groove A, 402, boss A, 5, preceding sealing cover, 501, the inclined-plane, 502, boss B, 503, groove B, 6, shell.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
With reference to accompanying drawing, a kind of electric sealing of spindles device comprises stator 1, preceding sealing cover 5, shell 6, it is characterized in that: described stator 1 is provided with preceding sealing cover 5, and preceding sealing cover 5 passes through scyewed joint with stator 1; The shell side is provided with protecgulum 4, on the protecgulum 4 on annular groove A401 and the preceding sealing cover 5 annular boss B502 be fastened togather, on the protecgulum 4 on annular boss A402 and the preceding sealing cover 5 annular groove B503 be fastened togather and constitute contactless labyrinth seal.Sealing cover 5 inboard cylindricals are provided with chamfering before described.Two sealing surfaces of described protecgulum 4 are provided with the pore that communicates.Described shell 6 is provided with sealing gland entrance 3, and sealing gland entrance 3 communicates with pore on the protecgulum 4.Sealing cover 5 exterior edge faces exceed protecgulum 4 exterior edge faces before described.During concrete enforcement, in the work before sealing cover with stator rotate at a high speed will be splashed to before most of liquid on the sealing cover throw away; Insert pressurized air by the sealing gland entrance, the liquid that enters between sealing cover and the protecgulum is blown out outward; The inboard cylindrical of preceding sealing cover is provided with chamfering, produces centrifugal force during preceding sealing cover rotates at a high speed and makes liquid can not enter electric main shaft inside.Play the effect of sealing.
