Abstract
Double End double-piston main shaft for a kind of lathe, by spindle main body, bearing, gland, main shaft, belt, oil cylinder and jig, formed, main shaft is rotatably connected in spindle main body by bearing, belt is connected to drive shaft on main shaft and rotates with the workpiece being held, the outside of bearing is fixed by gland, jig for holding workpiece is arranged on the two ends in spindle hole, jig is by hydraulic oil cylinder driving, wherein gland, bearing, oil cylinder and fixture are all arranged in pairs, and arrange along the longitudinal centre line almost symmetry of spindle main body.This lathe arranges by simple and effective structure with main shaft fixture, and clamped one time can be processed from the both ends of the surface of workpiece simultaneously, just can reach the requirement of concentric co-axial.
Description
Technical field
The utility model relates to Double End double-piston main shaft for a kind of lathe,, be particularly a kind ofly applied to numerical control, realize the rotatable shaft fixture that clamped one time can be processed from the both ends of the surface of workpiece simultaneously, belong to machining machinery manufacturing technology field.
Background technology
Along with the fast development of Digit Control Machine Tool, the numerous and confused Digit Control Machine Tool product of releasing separately of each lathe producer, Digit Control Machine Tool process technology has become some efficient, high accurately machined main modes of production at present.But in process of production, much coiling class, axial workpiece need to the processing of tune face, and the concentricity after processing cannot guarantee, and existing numerically controlled lathe also can only once be done a machined surface, thus to high request part, cannot meet, or the use that debases the standard.Restriction in this processing has limited the development of Digit Control Machine Tool significantly, becomes technical problem urgently to be resolved hurrily.
Utility model has overcome the shortcoming being showed with upper type structure at all, by simple and effective structure, arranges, and clamped one time can be processed from the both ends of the surface of workpiece simultaneously, just can reach the requirement of concentric co-axial.
Summary of the invention
The technical solution that realizes above-mentioned purpose is: Double End double-piston main shaft for a kind of lathe, , by spindle main body, bearing, gland, main shaft, belt, oil cylinder and jig form, main shaft is rotatably connected in spindle main body by bearing, belt is connected to drive shaft on main shaft and rotates with the workpiece being held, the outside of bearing is fixed by gland, jig for holding workpiece is arranged on the two ends in spindle hole, jig is by hydraulic oil cylinder driving, gland wherein, bearing, oil cylinder and fixture are all in a symmetrical arrangement, and arrange along the longitudinal centre line almost symmetry of spindle main body.
Wherein fixture can be chuck or chuck.
Lathe of the present utility model, has the following advantages with respect to prior art with main shaft fixture:
1, can carry out both ends of the surface processing by the coaxial same workpiece of clamping;
2, the coaxial clamping different workpieces of energy, guarantees the concentric co-axial degree of processing;
3, can be simultaneously or timesharing control the clamping of two chucks.
Accompanying drawing explanation
Accompanying drawing 1 is this lathe with Double End double-piston main shaft, main perspective schematic diagram.
Accompanying drawing 2 is Double End double-piston main shafts for lathe of the present utility model, A-A generalized section.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in accompanying drawing 1-2, Double End double-piston main shaft for a kind of lathe of the present utility model, by spindle main body 1, bearing, gland 2, main shaft 3, belt 4, oil cylinder 5 and jig 6 form, main shaft 3 is rotatably connected in spindle main body 1 by bearing, belt 4 is connected to drive shaft 3 on main shaft and rotates with the workpiece 7 being held, the outside of bearing is fixed by gland 2, jig 6 for holding workpiece 7 is arranged on the two ends in main shaft 3 holes, jig 6 is driven by oil cylinder 5, wherein gland 2, bearing, oil cylinder 5 and fixture 6 are all arranged in pairs, and arrange along the longitudinal centre line almost symmetry of spindle main body 1.Fixture 6 can be chuck or chuck.
Double End double-piston main shaft for a kind of lathe of the utility model can complete the processing of two parts under same drive condition.Same Part is added to man-hour its axiality and can be regarded as completely with one heart, time processing precision is high and be that same bus is beated, and tolerance is little.From design lathe angle, can design occupation of land less, the lathe such as lathe that timeliness is high, grinding machine, deep hole drilling machine.Its handling has improved processing beat greatly, saves time, power saving, province place.
Above-mentioned specific embodiment is described by example, should be understood that, these embodiment are subject to the impact of different distortion and optional form.It should also be further understood that, claim is not meaned and is limited to disclosed particular form, and should cover all distortion, the equivalence that drop in the utility model essence and scope, replaces and optional mode.
