Description

Novel integrated air-actuated jaw

Technical field

The present invention relates to novel integrated air-actuated jaws, are applied especially to mechanism and fix.

Background technology

China was in accession to WTO (World Trade Organization in 2001）, automobile market started unprecedented fast development. According to statistics, there are 130 She families in Chinese vehicle enterprise in 2012, is to possess vehicle enterprise in world car big country at most：10 before ranking Automobile Enterprises sales volume accounts for 83% or so, and 100 many enterprises to rank behind fight for the remaining market share.The relevant industry of automobile Occupy very important status in the development of Chinese national economy, the tertiary industry and related industry can greatly be promoted It is fast-developing.

Integral pneumatic fixture, as a kind of brightness clamps, main function is accurately fixed by the way that white body workpiece is carried out Position and reliable grip thereby may be ensured that the Pass dresses Jing Du during quick-fried dress He Play packing qualities, during improving quick-fried dress Quick-fried dress efficiency.The related air-actuated jaw as driving is caught up with using rod-pulling type gas, is the main Bai Che Shen Play clamps of China Today. Xiong Xiaoping has once done this relevant simple introduction, to this kind of using rod-pulling type cylinder as the several more typical of the fixture of driving Motion analyzed, be related to it Smoke dress efficiency and it is dry dress operation precision can all meet production requirement substantially.But It is since in the actual course of work, pure clamps can so use rod-pulling type gas in the working environment of a rather harsh Fixture of the cylinder as driving, its piston rod can be exposed to outside cylinder body, and making for cylinder can be reduced by continuously doing reciprocating motion Use the service life；Simultaneously in terms of the working performance of this kind of fixture, larger harmful impact forces are often generated in moment when clamping workpiece, Therefore workpiece surface quality can largely cause extremely bad influence, even damaged when serious, and this kind of Rod-pulling type fixture does not have the function of self-locking usually；In addition, sometimes in order to meet job requirement bright clamps is enable to export Larger clamping force, at this moment we have to increase cylinder bore or increase cylinder operation pressure to reach requirement, gas can be caught up with Cylinder diameter or operating pressure it is excessive.For the current advanced dry assembling production lines of white body, it would be desirable to be with controllability It is good, dry to fill fixture execution unit with high accuracy.

The content of the invention

In order to overcome the problems, such as that existing air-actuated jaw is not suitable for extraneous adverse circumstances, the present invention provides one kind new one Body formula air-actuated jaw, the novel integrated air-actuated jaw of the type have integral structure, also can be very under extraneous rugged environment Good work.

The technical solution adopted by the present invention to solve the technical problems is：The primary structure of Integral pneumatic fixture is by two It is grouped into, cylinder portion and linkage portion：Linkage portion is to be formed by penetrating section mechanism case with clamp arm, oval gas Cylinder is made of major parts such as rear end cap, ellipse cylinder barrel, drive end bearing bracket, piston and piston rods；Linkage portion when Section mechanism case is made of the major parts such as babinet, axis pin and needle bearing, connecting rod and rocking bar, babinet and shaft, entire gas Among the assembling of cylinder, the drive end bearing bracket of the elliptical cylinder of cylinder portion saves mechanism case bottom surface by bolt and Choi and is fastenedly connected, and presss from both sides Arm is connected together with shaft fixation in toggle mechanism case.

Integral pneumatic clamp cylinder part uses oblate cylinder, cylinder portion and linkage portion into During row connection, identical cross section not only makes connection simple, but also also assures that this Integral pneumatic fixture integrally seems More coordinate, volume is compacter.It is also easy to install during actual quick-fried dress, operation is more flexible.

The beneficial effects of the invention are as follows：It is to be rotatably assorted between the novel integrated air-actuated jaw babinet and shaft, entirely Clamp mechanism cylinder portion and linkage portion are affixed integral, totally enclosed structure can under extraneous rugged environment, It can be good at work.

Specific embodiment

Preferably, as shown in Figure 1 and Figure 2, it is mainly made of the primary structure of Integral pneumatic fixture two parts, cylinder Part and linkage portion：Elliptical cylinder 1 in cylinder portion such as figure, linkage portion are by penetrating section machine in Fig. 1 Structure case 2 is formed with clamp arm 3.

Preferably, elliptical cylinder 1 is by rear end cap, ellipse cylinder barrel, drive end bearing bracket, piston and piston rod etc. main zero Part forms；The time mechanism case of linkage portion be by babinet, axis pin A and axis pin B, needle bearing, connecting rod L2 and rocking bar L3, The major parts such as babinet and shaft form.

Preferably, among the assembling of entire cylinder, the drive end bearing bracket of the elliptical cylinder of cylinder portion by bolt and penetrates section Mechanism case bottom surface is fastenedly connected, and clamp arm is connected together with shaft fixation in toggle mechanism case, and piston-rod lower end portion passes through screw Be fixed together with piston, the upper end of piston rod by using axis pin A and connecting rod L2 and rolling meter bearing hinge connection, connecting rod L2 with Rocking bar L3 is hinged by axis pin B, and distant bar L3 is one with shaft, is to be rotatably assorted between babinet and shaft, entire clamp mechanism Cylinder portion is affixed integral with linkage portion, is known as Integral pneumatic fixture.

Preferably, since during fabrication, piston rod and internal running part are encapsulated within mechanism case, make this one The totally enclosed structure of body formula can also can be good at work under extraneous rugged environment.

Preferably, Integral pneumatic clamp cylinder part uses oblate cylinder, in cylinder portion and connecting rod machine When structure part is attached, identical cross section not only makes connection simple, but also also assures that this Integral pneumatic fixture is whole Body seems more to coordinate, and volume is compacter, is also easy to install during actual quick-fried dress, and operation is more flexible.

Preferably, carved at the beginning of work, the angle formed between clamp arm and horizontal direction is 45 °, in cylinder intake The compressed air with certain pressure is passed through at mouth C, compressed gas promotes piston upwards, and piston and piston rod, which are fixed, to be connected Together, piston rod is made also to move upwards, the needle bearing connected by axis pin can scroll up on the in vivo guide rail of case, together When connecting rod L2 is driven to rotate, the connecting rod L2 of rotation can drive rocking bar L3 to rotate again, and distant bar is one with shaft, and the rotation of shaft makes The clamp arm consolidated with it does clockwise rotation；When the top of piston upwards to cylinder barrel, the position of clamp arm at this time The final position of movement is set to, clamp arm is completed to clamp the action of workpiece.At this time between the location of clamp arm and horizontal direction Angle be 180, similarly, be passed through the gas with certain pressure at the air inlet D of cylinder, piston and piston can be driven Bar moves downward, and so as to which needle bearing can be driven to be moved downward on the in vivo guide rail of case, and then connecting rod L2 is driven to rotate, driven Rocking bar L3 and shaft negative direction rotate, and clamp arm rotates counterclockwise, and returns to initial time position.
