As improvement of the technical scheme, be provided with annular groove on the front end external diameter of body, the inboard correspondence position of driver plate is provided with annular groove, and the O RunddichtringO is arranged in two annular grooves driver plate is fixed on body.
As improvement of the technical scheme, be provided with oil pocket at the front end of body, be provided with piston in oil pocket, piston is done and is pumped in oil pocket.
As improvement of the technical scheme, described piston middle part is provided with annular groove, is provided with piston packing in annular groove.
As improvement of the technical scheme, described oil pocket arranges three, and distributes along the even circumferential of body front end, between oil pocket, is interconnected.
As improvement of the technical scheme, the repairing mouth is set on described oil pocket.
As improvement of the technical scheme, described driver plate front end is provided with moving tooth.
As improvement of the technical scheme, described moving tooth and driver plate are the integral type structure.
As improvement of the technical scheme, described driver plate front end is provided with screw, and screw extruding moving tooth is fixed on driver plate.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
The Excircle machining fixture of clamped one time described in the utility model, by sliding top and moving tooth Dual positioning support, guarantee that clamped one time can realize Excircle machining.Also be provided with a plurality of oil pockets on fixture, adapt to the workpiece of different end faces, improve the adaptability of fixture.Process and use by reality, this clamp structure is simple, and machining accuracy is high, and implementation result is remarkable.
The accompanying drawing explanation
The Excircle machining clamp structure schematic diagram that Fig. 1 is clamped one time described in the utility model;
Fig. 2 is a kind of moving tooth fixed structure schematic diagram in Excircle machining fixture described in the utility model.
The specific embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1, be the Excircle machining clamp structure schematic diagram of clamped one time described in the utility model.Excircle machining fixture described in the utility model, comprise body 1, and slip addendum cone 7 is arranged on the inside of body 1, and dog screw 6 is limited to body 1 inside by slip addendum cone 7 and only can endwisely slips, and can not mutually rotate.Driver plate 9 is sleeved on the front end of body 1.In the rear end of slip addendum cone 7, be provided with steady arm 4, steady arm 4 front ends are provided with nut 5, and rear end is provided with hexagonal spiro plug 6.Be provided with butterfly spring 3 on the steady arm 4 between nut 5 and hexagonal spiro plug 6, butterfly spring 3 is in its pre-compressed state.Hexagonal spiro plug 6 by with body 1 on threaded engagement, butterfly spring 3 is compressed in to body 1 inside.
Be provided with annular groove on the front end external diameter of body 1, the inboard correspondence position of driver plate 9 is provided with annular groove, and O RunddichtringO 8 is arranged in annular groove, and driver plate 9 is fixed on body 1.
Front end at body 1 is provided with oil pocket 12, is provided with piston 10 and appropriate hydraulic oil in oil pocket 12, and piston 10 is done and pumped in oil pocket 12.Piston 10 middle parts are provided with annular groove, are provided with piston packing 11 in it, guarantee like this sealing between piston 10 and oil pocket 12.
Piston 10 front ends are square head-shaped, and piston 10 front ends are stuck in the groove of driver plate 9 end faces, as shown in Figure 1.When processed workpiece end face and its center line out of plumb, while being the end face out of plumb of rotating center axis and 7 supports of slip addendum cone, it is more that one of them piston 10 is pressed into oil pocket 12, piston 10 is corresponding is adjusted for two other, stretch out a part as a supplement, thereby the square toes that guarantee piston 10 fully contact all the time with driver plate 9 end face grooves, guarantee normal operation.
