Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of air-actuated jaw described in the utility model, comprises base plate 1, floor board framing 2, cylinder 3, push rod 4, boosting-rod 5 and slide block 6.Base plate 1 is installed on floor board framing 2, base plate 1 offers the first through hole 19, base plate 1 is fixedly equiped with jaw 1.
Described base plate 1 is fixedly equiped with guiding device for slide block 11, and guiding device for slide block 11 comprises leading truck 12 and gib block 13, and gib block 13 is installed on leading truck 12, and leading truck 12 and gib block 13 form gathering sill 14, and gathering sill 14 is low wide and up narrow.The profile of slide block 6 is corresponding with gathering sill 14 adaptive, and slide block 6 is sleeved in gathering sill 14, and slide block 6 is straight line slippage in gathering sill 14.Gathering sill 14 can limit the slippage route of slide block 6, the skew of the slip locations of anti-limited slip block 6.Slide block 6 bottom offers groove 21, slide block 6 is equiped with jaw 28, and jaw 1 is relative with the opening of jaw 28.
Bearing pin mount pad 16 is set with in described first through hole 19, bearing pin mount pad 16 is fixed by screws on base plate 1, bearing pin mount pad 16 has biside plate 17, side plate 17 offering the jack 18 for installing bearing pin 2 10, bearing pin mount pad 16 offering the second through hole 20.
Described cylinder 3 to be fixed on floor board framing 2 and to be positioned at below base plate 1, and push rod 4 is fixedly connected with the piston rod 23 of cylinder 3, and boosting-rod 5 is flexibly connected with push rod 4 one end away from piston rod 23 by bearing pin 1.Boosting-rod 5 stretches in the groove 21 of slide block 6 through the second through hole 20, and boosting-rod 5 offers pin shaft hole 22 near upper end, is coated with bearing pin 2 10 in pin shaft hole 22, and bearing pin 2 10 two ends are through on the jack 18 of bearing pin mount pad 16 side plate 17.Cylinder 3 promotes boosting-rod 5 by push rod 4 and rotates around bearing pin 2 10, and slide block 6 is with swing straight line slippage on base plate 1 of boosting-rod 5.Boosting-rod 5 is offered the position end on the upper side of pin shaft hole 22, this makes boosting-rod 5 lower end be greater than the distance of boosting-rod 5 upper end apart from pin shaft hole 22 apart from the distance of pin shaft hole 22.Like this, due to the effect of lever principle, cylinder 3 promotes boosting-rod 5 and rotates, can under less cylinder thrust, to the thrust that slide block 6 is enough, and then makes jaw 28 and jaw 1 can clamping work pieces 100.Like this, workpiece 100 is in Milling Machining process, and this air-actuated jaw can bear larger cutting force, meets Production requirement.
This air-actuated jaw is in the production process of batch clamping workpiece 100, and due to workpiece 100 and the interaction of air-actuated jaw, can be worn and torn in clamping workpiece 100 place.In order to ensure the clamping precision of workpiece 100, described base plate 1 is also equiped with workpiece cushion block 15, workpiece cushion block 15 is fixed by screws on base plate 1, and workpiece cushion block 15 is between jaw 1 and jaw 28.Like this, workpiece cushion block 15 upon wear, can be changed at any time, not only ensures the stability of clamping, and only needs to change workpiece cushion block 15, without the need to changing whole air-actuated jaw, reduces production cost.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
