Abstract
The utility model belongs to a machine tool spindle clamping device, which mainly consists of a clamping sleeve, a piston, a piston sleeve, pressure pipelines and the like. The clamping sleeve is disposed on the outer diameter of a spindle, the piston and the piston sleeve are arranged on the clamping sleeve, the clamping sleeve is an inclined wedge sleeve, the portion, which is combined with the inclined wedge surface of the clamping sleeve, of the piston is an inclined surface, and the pressure pipelines which are used for applying and releasing pressure are disposed in the piston sleeve and the clamping sleeve. The pressure pipeline in the piston sleeve applies pressure to the piston, the inclined surface of the piston squeezes the inclined wedge surface of the clamping sleeve, so that the clamping sleeve deforms radially to lock the spindle, and the spindle cannot rotate. The machine tool spindle clamping device has the advantages of simple structure, convenience in machining, low cost, high locking reliability and the like.
Description
Affiliated field
The utility model belongs to machine spindle clamping structure device, is particularly useful for large-scale or heavy machine tool axis clamping structure.
Background technology
At lathe, especially milling-lathe machining center carries out needing accurate angle orientation of main shaft and calibration under the situation of turning and milling conversion.When milling-lathe machining center machining shape, baroque workpiece, need turning to process inside and outside circle, on the surface of the work under the situation of milling plane curved surface, its main shaft will change the state of main shaft according to operating mode, at any time between turning and milling, change, and require main shaft can be when stopping the rotation can stable stopping.In turning and milling conversion that milling-lathe machining center adopted, the scheme that reaches the spindle index location is at present: inside and outside gears engaged conversion, mouse tooth disk engagement conversion, swallow-tail form clamping structure etc.
Summary of the invention
The purpose of this utility model is, at machine spindle in the prior art can not fine locking problem, design a kind of structure that can solve machine spindle locking.
The said machine spindle clamping device of the utility model mainly is made up of chucking cover, piston, piston bush, pressure piping etc.Chucking is set on the external diameter, and the chucking cover is provided with piston and piston bush, and said chucking cover is the wedge cover, puts cammed surface piston combining part with chucking and also is the inclined-plane; In said piston bush and chucking cover, be provided with the pressure piping of exerting pressure with pressure release.
Adopt the said machine spindle clamping device of the utility model, exert pressure to piston by pressure piping in the piston bush, piston moves axially in piston bush, combine with the chucking cover, by the extruding of the inclined-plane on the piston to chucking cover wedge, make chucking cover radial deformation lock shaft, axle can not be rotated.Advantages such as the said axis clamping constructional device of the utility model has simple in structure, easy to process, and with low cost and reliable lock is strong.
Description of drawings
Accompanying drawing 1: shaft clamping device structural representation.
The specific embodiment
What provide in the accompanying drawing 1 is to be the machine spindle clamping device structural representation that example provides with the turn-milling machine tool.
The said machine spindle clamping device of the utility model is made up of chucking cover 1, piston 2, piston bush 3, pressure piping 4 etc.Chucking cover 1 is arranged on axle 5 external diameters, and chucking cover 1 is provided with piston 2 and piston bush 3, and said chucking cover 1 be the wedge cover, overlaps with chucking that cammed surface 6 piston combining 2 parts also are the inclined-plane on 1; In said piston bush 3 and chucking cover 1, be provided with the pressure piping 4 of exerting pressure with pressure release.Said pressure piping 4 can be fluid pressure line or pneumatic circuit.
Said chucking cover 1 can be in groups a wedge cover more than 2 or 2, also can be to put the structure that the cammed surface position is provided with the radial opening groove at a chucking.
Be fixed on piston bush and chucking cover on the housing of axle by fixture, exert pressure to piston by the pressure piping in piston bush, piston is moved axially in piston bush and combine with chucking cover, by the extruding of piston to chucking cover wedge, thereby chucking cover radial deformation lock shaft can not rotate axle.In accompanying drawing 1, what its first half provided is the work condition state of not exerting pressure to piston; When the Lower Half of axle then has pressure for the pressure pipeline in the piston bush, the inclined-plane that makes piston after chucking cover wedge cover is exerted pressure, the work condition state of lock shaft.
