Abstract
The invention discloses a double-end-face double-piston spindle for a machine tool. The spindle comprises a spindle main body, bearings, glands, a spindle, a belt, oil cylinders and fixtures, wherein the spindle is rotationally connected to the interior of the spindle main body through the bearings; the belt is connected with the spindle to drive the spindle and a clamped workpiece to rotate; the outer sides of the bearings are fixed by the glands; the fixtures for clamping the workpiece are arranged at two ends in a spindle hole; the fixtures are driven by the oil cylinders; the glands, the bearings, the oil cylinders and the fixtures are arranged in pairs and basically and symmetrically arranged along the longitudinal center line of the spindle main body. The spindle fixtures for the machine tool can be simply and effectively configured in the structure to allow the two end faces of the workpiece to be processed at the same time by clamping for one time, so as to meet the concentric and coaxial requirements.
Description
Technical field
The present invention relates to a kind of lathe Double End double-piston main shaft,, particularly one is applied to numerical control, realizes the rotatable shaft fixture that clamped one time can be processed from the both ends of the surface of workpiece simultaneously, belongs 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 concentricity after processing cannot ensure, and existing numerically controlled lathe also can only once be done a machined surface, thus cannot meet high request part, 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.
The present invention has overcome the shortcoming being showed with upper type structure at all, arranges by simple and effective structure, 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 composition, 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 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 invention, 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, ensures the concentric co-axial degree of processing;
3, can be simultaneously or the clamping of two chucks of timesharing control.
Brief description of the drawings
Accompanying drawing 1 is this lathe with Double End double-piston main shaft, main perspective schematic diagram.
Accompanying drawing 2 is lathe of the present invention Double End double-piston main shafts, A-A generalized section.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in accompanying drawing 1-2, Double End double-piston main shaft for a kind of lathe of the present invention, 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.
The present invention is Double End double-piston main shaft for a kind of lathe, can under same drive condition, can complete the processing of two parts.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, replaces and optional mode and should cover all distortion, the equivalence that drop in essence of the present invention and scope.
