The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the full-floating type pneumatic gripping of present embodiment, comprise upper clamp 1, lower clamp 14, jaw plate 2, cylinder and retaining mechanism, upper clamp 1 middle part and lower clamp 14 are hinged by bearing pin 4, upper clamp 1 rear portion is connected by bearing pin 12 with the tail end of cylinder piston rod 11, and jaw plate 2 is fixed on the upper clamp 1 by screw 3; Cylinder comprises cylinder block 10, piston rod 11 and cylinder cap 5, cylinder block 10 is fastening by bolt 13 and lower clamp 14, cylinder cap 5 is fixed on the cylinder block 10 by securing member, piston rod 11 is positioned at cylinder block 10, piston rod 11 seals by O-ring seals (not marking among the figure) with cylinder block 10 internal face contact positions, prevents gas leakage, reduces wear, and be provided with back-moving spring 9 between piston rod 11 and the cylinder cap 5, be provided with passage a on the piston rod 11; The both sides, front and back of cylinder block 10 have through hole, are provided with linear roller bearing 16 in the through hole, penetrate guide pillar 15 in the linear roller bearing 16, and the through hole of cylinder body holder 7 ends is also passed at guide pillar 15 tops, and fix by jump ring (not marking among the figure) and securing member; A side that is positioned at cylinder block 10 is fixed with cylinder body holder 7 by securing member.Cylinder body holder 7 bottoms are provided with the adjustment screw 17 of regulating the gap between cylinder body holder 7 and the cylinder block 10; Cylinder body holder 7 ends have through hole, pass through bolt 19 holddown springs 18 in the through hole.
See Fig. 4 and Fig. 5, the tail end of piston rod 11 is tang 21, on the described tang 21 circular hole is arranged, have the first U-lag 20 on the upper clamp 1 posterior transversal direction, have the second U-lag 22 on its longitudinal direction, described piston rod 11 tangs 21 penetrate in second U-lag 22 at upper clamp 1 rear portion, and pass circular hole and the first U-lag 20 location of tang 21 with bearing pin 12.
See Fig. 1, the structure of retaining mechanism is: an end of cylinder body holder 7 is provided with the dovetail groove 701 that is connected with machine, cylinder body holder 7 tops are passed stage clip 6 by screw and are fixed with panel 8, be used for regulating the gap of dovetail groove 701, it is more reliable and more stable to guarantee that dovetail groove is connected with machine, makes the clamp conveniently moving.
Practical work process is as follows:
See Fig. 1, when compressed air enters in the cavity of cylinder from passage a, thereby pushing piston bar 11 moves up, piston rod 11 the foot section brought untie-sell axles 12 make upper clamp 1 rotate counterclockwise around bearing pin 4 relative lower clamps 14, press on the jaw plate 2 upper clamp 1 front end termination, thus the sheet material on the clamping clip oralia 2; When compressed air disappears, because piston rod 11 under the effect of back-moving spring 9, moves down piston rod 11, the gas in the cylinder block 10 is by the discharge of the passage a on the cylinder cap 5, so that upper clamp 1 turns clockwise around bearing pin 4, clamp unclamps sheet material.Because the effect of guide pillar 15, guide pillar 15 is connected with cylinder body holder 7, cylinder block 10 and the retaining mechanism that is connected slide at guide pillar 15 axis directions by connected linear roller bearing 16, in the sheet material process, when sheet material moves at workbench, fluctuate with the height of table variation, clamp mechanism also fluctuates with it, keeps highly consistent with cutter so guarantee sheet material all the time in process, be conducive to the plate stamping crudy, good stability.Spring 18 its effects that bolt 19 compresses are to guarantee that sheet material does not contact with workbench all the time can be in vacant state.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
