Abstract
The utility model discloses a wide pneumatic finger air cylinder which comprises a first piston and a second piston. Two ends of the first piston are respectively provided with first piston rods. Two ends of the second piston are respectively provided with second piston rods. The wide pneumatic finger air cylinder further comprises a first finger and a second finger. Each finger is connected with the corresponding first piston rod and the corresponding second piston rod through guide rods. Each first piston rod and each second piston rod are respectively provided with a first rack and a second rack and gears bonding to the first rack and the second rack in a matched manner. The wide pneumatic finger air cylinder has the advantages that by the double-piston structure, the force exerted by the air cylinder is multiplied, the clamping force is large, and the clamping force can be provided continuously; each finger is respectively connected with the corresponding first piston rod and the corresponding second piston rod through two guides rods for guidance, linkage of the two fingers is achieved by the gear-rack bonding mechanism, repeated positioning precision of the fingers is high, and a clamping function can be achieved when the fingers are spread or closed.
Description
Technical field
The utility model relates to finger cylinder, in particular a kind of wide type pneumatic-finger cylinder.
Background technique
Cylinder is widely used in automatic line, assembly line, the fields such as five metals, mechanical frock fixture.When workpiece is when a station is transformed into another station, need the clamping and positioning in certain direction, cylinder is realized location as the thrust mechanism clamping work pieces of exerting oneself, that is: workpiece is clamped at and between cylinder and fixture, realizes location.
There is following shortcoming in it:
1. generally, when workpiece is when a station is transformed into another station, if while requiring positioning precision higher when workpiece is changed station more in other words, stable not, safety during holding workpiece, location progress is not high, has larger potential safety hazard;
2. common finger cylinder chucking power is little.
Therefore, there is defect in prior art, needs to improve.
Model utility content
Technical problem to be solved in the utility model is: a kind of chucking power that can continue to provide is stably provided, and clamping great efforts, compact to design, conserve space, the high wide type pneumatic-finger cylinder of finger repetitive positioning accuracy.
The technical solution of the utility model is as follows: a kind of wide type pneumatic-finger cylinder, comprise first piston and the second piston, and the two ends of described first piston arrange respectively first piston bar, and the two ends of described the second piston arrange respectively the second piston rod; And, also comprising the first finger and second finger, each finger is connected with each second piston rod with each first piston bar by guide rod respectively; On described first piston bar, described the second piston rod, the first tooth bar and the second tooth bar are also set respectively; And, also arrange respectively and described the first tooth bar and the adaptive gear binding of described the second tooth bar.
Adopt such scheme, the utility model is by adopting dual-piston structure, makes the cylinder multiplication of exerting oneself, and clamps great efforts, can continue to provide stably chucking power; And, by each finger, adopt two guide rods to be connected and to lead with the second piston rod with first piston bar respectively, adopt gear rack to bind mechanism simultaneously, realize two finger interlocks, finger repetitive positioning accuracy is higher, and finger opens can realize holding function with closing all.
Accompanying drawing explanation
Fig. 1 is structural representation one of the present utility model.
Fig. 2 is structural representation two of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The present embodiment provides a kind of wide type pneumatic-finger cylinder, and described wide type pneumatic-finger cylinder is by adopting dual-piston structure, and chucking power is large, holder's parts are reliable and stable, and, by adopting gear rack to bind, positioning precision is high, and opening of finger can realize holding function with closing all.
As shown in Figure 1, wide type pneumatic-finger cylinder comprises first piston 4 and the second piston 9, and the two ends of first piston 4 arrange respectively first piston bar 2 and first piston bar 5, and the two ends of the second piston 9 arrange respectively the second piston rod 8 and the second piston rod 10.
And, wide type pneumatic-finger cylinder also comprises the first finger 1 and second finger 7, the first finger 1 is connected with each second piston rod with each first piston bar by guide rod respectively with second finger 7, be that each finger is connected with each second piston rod with each first piston bar respectively by two guide rods that arrange, there are two guide rod guide structures.
As shown in Figure 2, described first piston bar is fixedly installed the first tooth bar 12, and described the second piston rod is fixedly installed the second tooth bar 13, and, also arrange respectively and the first tooth bar 12 and the adaptive gear 11 binding of the second tooth bar 13.
So, when first piston 4 is subject to air pressure pressure, first piston 4 setting in motions, by gas circuit, exchanging the second piston 9 moves immediately, bonding by gear 11 respectively and between the first tooth bar 12 and the second tooth bar 13 links, by each first piston bar and each second piston rod, drive respectively each guide rod, thereby realize the first finger 1 and second finger 7 interlocks, realize Workpiece clamping and the effect of loosening.And, for preventing that high-pressure cutting fluid, cutting powder from entering, cause that action is bad, while changing folder workpiece, can between two fingers, carry out air purging.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
