Background technology:
As everyone knows; In cutting the equipment of coiled strip; And in the cutting apparatus of the set coiled strip that reaches in fields such as electronics, photoelectricity, packing, printing; Rotate for coiled strip is placed on the transmission main shaft, need to use pneumatic chuck or internal-expansion type inflatable axle that coiled strip is gripped, realize the synchronous rotation of coiled strip and transmission main shaft.
Common in the market pneumatic chuck has the external clamping pneumatic chuck.The external clamping pneumatic chuck is clamped in jaw on the coiled strip through the air chamber expansion, realizes the synchronous rotation of coiled strip and transmission main shaft, and there is certain deficiency in this external clamping pneumatic chuck: complex structure, parts are more, installation and trouble thereof etc.
Common in the market internal-expansion type inflatable axle is through the air bag expansion plate to be expanded to realize the purpose that material clamps, thereby with the clamping of coiled strip end, realizes the synchronous rotation of coiled strip and transmission main shaft; Internal-expansion type inflatable axle utilizes the inner core of the expansion swelling coiled strip of air bag usually, and this internal-expansion type inflatable axle exists certain not enough: the gas pressure intensity that can bear is little, and large diameter coiled strip weight is big; Therefore air bag seems painstakingly to the clamping of major diameter coiled strip, can't firm, reliable clamping coiled strip, occur easily becoming flexible; In case take place to become flexible, will influence the accuracy of operations such as cutting, even occurrence of waste; If want to strengthen gas pressure, can shorten the service life of air bag again, even damage air bag; Strengthen contact area, promptly can influence and cut quality, also can't reach application target.
For solving above-mentioned deficiency of the prior art, the applicant proposes a kind of new solution.
The utility model content:
The purpose of the utility model is to overcome the weak point of existing pneumatic chuck, and a kind of interior external clamping pneumatic chuck that expands is provided, and it is the clamping coiled strip securely.
The utility model realizes that the technical scheme that its purpose adopts is: external clamping pneumatic chuck that expands in this comprises connecting bushing, cutting main shaft, main shaft; The cutting main shaft is installed on the connecting bushing; Connecting bushing one end is provided with air admission hole, and other end inboard is provided with piston, spring, and connecting bushing is provided with several claws; Claw one end is equipped with little bearing, and little bearing is resisted against on the piston; Main shaft is installed on the cutting main shaft, is arranged with cushion rubber on the main shaft, is provided with the inflatable push jack between cushion rubber and the cutting main shaft; On the cutting main shaft several removable pins are installed, wherein removable pin one end is resisted against on the piston, and the other end is resisted against on the inflatable push jack.
In the technique scheme, said connecting bushing is provided with several flutings that cooperates with claw, and claw is positioned at fluting, and is articulated on the connecting bushing through the claw pin.
In the technique scheme, said cutting main shaft is provided with the cavity that several cooperate with claw, and the cutting main shaft is provided with the through hole that several cooperate with removable pin, and removable pin is positioned at through hole.
In the technique scheme, said piston is provided with the inclined-plane that supplies little bearing to slide.
After adopting said structure, the utlity model has following advantage:
1, the utility model adopt pneumatic outer folder and pneumatic in the mode that expands coiled strip is fixed on the main shaft, so not only can the material that the paper tube head is arranged be clipped but also can the material clip of no paper tube head is firm.
2, the utility model is to utilize the elastic force of spring with piston reset, has not only reduced production cost but also reduced maintenance cost, has reached assembling, has safeguarded easy purpose.
3, the utility model is converted to thrust through power conversion from the expansion of pressure, makes it to expand through the extruding of thrust to cushion rubber, is convenient to judge its operating position and can directly safeguards.
4, the utility model realizes filling automatically exhaust through the PLC centre routine; Can realize to coiled strip quick loading and unloading, clamp fast, maintenance cost is reduced to less than one of five percentages of the maintenance cost of air bag inflatable axle, minimumly generally speaking can reach 10 years, not have for 1,000,000 times and safeguard.
Description of drawings:
Fig. 1 is the stereogram of the utility model;
Fig. 2 is the exploded perspective view of Fig. 1.
The specific embodiment:
Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.
See shown in Figure 1ly, present embodiment the utility model comprises: connecting bushing 1, cutting main shaft 2, main shaft 3.
Particularly: above-mentioned cutting main shaft 2 is installed on the connecting bushing 1, and connecting bushing 1 one ends are provided with air admission hole, and other end inboard is provided with piston 4, spring 5; Connecting bushing 1 is provided with four claws 6; Connecting bushing 1 is provided with four flutings 7 that cooperate with claw 6, and each claw 6 lays respectively at respectively slots in 7, and is articulated on the connecting bushing 1 through claw pin 8; These claw 6 one ends are equipped with little bearing 13, and little bearing 13 is resisted against on the piston 4.Be provided with the inclined-plane 41 that supplies little bearing 13 to slide in piston 4.
Above-mentioned main shaft 3 is installed on the cutting main shaft 2, is arranged with cushion rubber 9 on the main shaft 3, and wherein, this cushion rubber 9 is the wear-resistant seal cushion rubber, is provided with inflatable push jack 10 between cushion rubber 9 and the cutting main shaft 2.Four removable pins are installed on this cutting main shaft 2, and wherein removable pin one end is resisted against on the piston 4, and the other end is resisted against on the inflatable push jack 10.This cutting main shaft 2 is provided with four cavitys 11 that cooperate with claw 6, and cutting main shaft 2 is provided with four pin-and-holes that cooperate with removable pin 12, and removable pin is positioned at pin-and-hole 12.
When cutting volume work when beginning to need the coiled strip on the clamping spindle 3; Compressed air gets into connecting bushing 1 promotion piston 4 from air admission hole and advances, and piston 4 promotes removable pins and advances, and removable pin will promote inflatable push jack 10 and advance; Inflatable push jack 10 will push cushion rubber 9, and cushion rubber 9 is with the hollow part swelling of coiled strip inner core; Meanwhile, under the effect of air pressure, promote piston 4, little bearing 13 slides on the end face 42 along inclined-plane 41, and piston 4 makes claw 6 other ends tightly be clamped on the coiled strip little bearing 13 jack-up at this moment, thereby realizes the synchronous rotation of coiled strip and connecting bushing 1.When cutting volume operation completion need unclamp the coiled strip on the main shaft 3 time, compressed air releases from air admission hole, and piston 4 is retreated under the effect of spring 5, and cushion rubber 9 restores automatically, thereby loses tension force, and meanwhile, claw 6 unclamps automatically.
Certainly; The above is merely an embodiment of the utility model; Be not to limit the utility model practical range, all equivalences of doing according to the said structure of the utility model claim, characteristic and principle change or modify, and all should be included in the utility model claim.
