Description
Technical field
The utility model relates to a kind of rotary table mechanical gripping means of horizontal Machining centers.
Background technology
Rotary table is the key feature of horizontal Machining centers, is realizing the straight-line workpiece circular index of finishing simultaneously of lathe, and a clamping realization is to the processing of each face of workpiece.Rotary table reply work top is reliably located and is clamped in the workpiece process, and rotary table unclamps work top when needing the exchange of circular index or work top.
It is multiple that the work top positioning and locking mode that the horizontal Machining centers rotary table is commonly used both at home and abroad mainly contains T type supporting plate tension formula, steel ball Draw bar lock compact form, elasticity inclined-plane locking type, lever plane compression type etc. at present.T type supporting plate tension formula, elasticity inclined-plane locking type and lever plane compression type clamp mechanism are extensively adopted by lathe producer, but these three kinds of clamp mechanism modes that adopt four conical surface positioning supports or center support more, the clamping force and the work top strong point often can not be concentric, make work top under the effect of clamping force, produce extra distortion, directly influence rotary table table top precision, and then influence the machining accuracy of lathe.Though steel ball Draw bar lock compact form clamp mechanism has realized clamping force is acted on the positioning supports face, the application point of power is reasonable, and the work top rigidity is better, and by the locking of steel ball realization to work top, clamping force is less relatively.Above-mentioned several clamp mechanism all adopt hydraulic clamp, hydraulic unlock simultaneously, and the fault rate of hydraulic system own is higher, and problems such as pipeline leakage often cause said mechanism to clamp inefficacy, and reliability is lower.
The load-carrying of large-size horizontal machining center rotary table is bigger, and often more than 10t, the pattern of slip circular guideway is adopted in gyration usually, requires that the clamping device clamping force is big, reliability is high, and common clamping device is difficult to meet the demands.
Summary of the invention
The purpose of this utility model provides and a kind ofly utilizes dish spring mechanical grip, hydraulic unlock, clamping force is big and the rotary table mechanical gripping means of the horizontal Machining centers of adjustable, good reliability, overcomes the deficiencies in the prior art.
The rotary table mechanical gripping means of horizontal Machining centers of the present utility model comprises slide seat body that is positioned at the below and the workbench that is positioned at the top between slide seat body and workbench slide guide rail being arranged; Penetrated the axis of the piston between slide seat body and the workbench, the below of the axis of the piston plug of taking over a job is furnished with oil cylinder mutually with piston, and piston bottom end face and oil cylinder bottom form cavity of resorption and also be connected with hydraulic oil port, and screw thread is connected with binding nut in the upper end of the axis of the piston; The dish spring that is enclosed within on the axis of the piston is arranged above piston and in the epicoele that forms between the oil cylinder top.
The rotary table mechanical gripping means of horizontal Machining centers of the present utility model, wherein said binding nut are adjusted nut by pretension and are formed with the locking nut that is positioned at pretension adjustment nut top; Pretension adjust be set with on the axis of the piston below the nut match on spheric washer and lower peripheral surface packing ring.
The rotary table mechanical gripping means of horizontal Machining centers of the present utility model is provided with sealing shroud between wherein said slide seat body and the axis of the piston.
The rotary table mechanical gripping means of horizontal Machining centers of the present utility model, be to utilize dish spring mechanical grip mode, clamping force is big, and is safe and reliable, and can adjust the size of clamping force, clamping force directly acts on slide guide rail, simple in structure, flexible movements can not cause the extra distortion of work top, even can guarantee reliable grip when hydraulic fault occurring, relevant accident can not appear yet.
