Abstract
The utility model discloses a headstock of a lathe, belonging to the technical field of lathes. The headstock comprises a headstock body and a main shaft arranged in the headstock body in a penetrating manner, wherein a double-row cylindrical roller bearing and an angular contact bearing are arranged between the front part of the main shaft and the headstock body, a double-row cylindrical roller bearing is arranged between the rear part of the main shaft and the headstock body, and a labyrinth seal is arranged outside the bearing at the front part of the main shaft. The headstock has the beneficial effects that water-oil mixtures, such as cooling liquid, are effectively prevented from entering the headstock so as to reduce abrasion of the bearings of the main shaft; the cutting rigidity can be increased, the processing precision of the main shaft and the surface smoothness of a workpiece are ensured; good centering property is realized so that the rotation precision of a belt transmission and rotation oil cylinder is greatly improved, thereby prolonging the service life of the bearings.
Description
Technical field
The utility model relates to the machine tool technology field, particularly a kind of spindle stock.
Background technology
Headstock is the vitals of lathe, be used to arranging lathe working-spindle and driving parts thereof and corresponding additional mechanism providing additional operation.Main shaft in headstock is the vital part of lathe, and it is arranged in headstock by bearing, and the kinematic accuracy of main shaft and the rigidity of structure are the key factors that determines crudy and stock-removing efficiency.
There are some problems in the headstock used on lathe at present: 1, the headstock sealing property is undesirable, and main shaft has the water oil mixture such as cooling fluid to enter often in cutting process, the main shaft bearing wearing and tearing are accelerated, and even directly damages; 2, at lathe, carry out heavy cut and add man-hour, main shaft bearing rigidity deficiency, affect crudy; When 3, being connected in the belt pulley at main shaft rear portion and rotary oil cylinder and rotating, the centrifugal force of generation is larger, affects the main shaft bearing life-span.
The utility model content
Technical problem to be solved in the utility model is to overcome the problems referred to above, and a kind of spindle stock is provided, good seal performance not only, and can guarantee motion of main shaft precision and cutting rigidity, extend the main shaft life-span.
The technical solution of the utility model is:
A kind of spindle stock, comprise casing and be arranged in the main shaft in casing, it is characterized in that: between main shaft front portion and casing, be provided with Biserial cylindrical roller bearing and angular contact bearing, be provided with Biserial cylindrical roller bearing between main shaft rear portion and casing, the bearing outside of main shaft front portion is provided with labyrinth seal.
Main shaft hollow described in the utility model, be provided with pull bar in it, front-end of spindle fixed installation chuck, and the sheathed belt pulley in rear end, belt pulley is connected with rotary oil cylinder, and the pull bar two ends are connected with rotary oil cylinder with chuck respectively.
The bearing outside of main shaft described in the utility model front portion also is provided with bearing gland No. one, and the bearing outside at main shaft rear portion is provided with bearing gland No. two.
The beneficial effects of the utility model are:
1, main shaft is anterior adopts the multiple tracks labyrinth seal, can prevent effectively that the water oil mixture such as cooling fluid from entering headstock, thereby reduce the main shaft bearing wearing and tearing;
2, anterior Biserial cylindrical roller bearing and the angular contact bearing of adopting of main shaft is used in conjunction with, and can increase the cutting rigidity, guarantees the machining accuracy of main shaft and the surface smoothness of workpiece;
3, Biserial cylindrical roller bearing is adopted at the main shaft rear portion, has good aligning performance, and the rotation precision of belt transmission and rotary oil cylinder is greatly improved, thereby extends the life-span of bearing.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the enlarged drawing at A place in Fig. 1;
Fig. 3 is the enlarged drawing at B place in Fig. 1.
The specific embodiment
Now by reference to the accompanying drawings the utility model is further described:
As shown in Figure 1-Figure 3, a kind of spindle stock, comprise casing 1 and be arranged in the main shaft 2 in casing 1, main shaft 2 hollows, be provided with pull bar 7 in it, main shaft 2 front end fixed installation chucks 8, the sheathed belt pulley 9 in rear end, belt pulley 9 is connected with rotary oil cylinder 10, and pull bar 7 two ends are connected with rotary oil cylinder 9 with chuck 8 respectively, and rotary oil cylinder 9 is controlled 8 pairs of workpiece of chuck by pull bar 7 and clamped and loosen.
Between main shaft 2 front portions and casing 1, Biserial cylindrical roller bearing 3 and angular contact bearing 4 are set, these two kinds of bearing fits are used, and can bear bi-directional axial load, increase the cutting rigidity, and the machining accuracy of assurance main shaft 2 and the surface smoothness of workpiece are just; Between main shaft 2 rear portions and casing 1, Biserial cylindrical roller bearing 5 is set, the rotation precision of belt pulley 9 and rotary oil cylinder 10 is greatly improved, thereby extend the life-span of bearing.In addition, the bearing arranged outside multiple tracks labyrinth seal 6 of main shaft 2 front portions, the water oil mixtures such as cooling fluid are subject to the purpose that resistance reaches Drain Resistance when the gap by tortuous labyrinth, reduce main shaft 2 bearing wears.
The bearing outside of main shaft 2 front portions also is provided with bearing gland 11 No. one, and the bearing outside at main shaft 2 rear portions is provided with bearing gland 12 No. two.
Claims (3)
1. spindle stock, comprise casing and be arranged in the main shaft in casing, it is characterized in that: between main shaft front portion and casing, be provided with Biserial cylindrical roller bearing and angular contact bearing, between main shaft rear portion and casing, be provided with Biserial cylindrical roller bearing, the bearing outside of main shaft front portion is provided with labyrinth seal.
2. according to a kind of spindle stock claimed in claim 1, it is characterized in that: main shaft hollow is provided with pull bar in it, front-end of spindle fixed installation chuck, the sheathed belt pulley in rear end, belt pulley is connected with rotary oil cylinder, and the pull bar two ends are connected with rotary oil cylinder with chuck respectively.
3. according to the described a kind of spindle stock of claim 1 or 2, it is characterized in that: the bearing outside of main shaft front portion also is provided with bearing gland No. one, and the bearing outside at main shaft rear portion is provided with bearing gland No. two.
