The distance between spring retainer block 26 and the end face of the positioning limiting fixator change, to adjust the pressure of the buffer spring 25
Contracting amount.
In practical applications, the size of cushion effect is adjusted by the interaction of spring and push rod.Push rod insertion depth is got over
Long, spring-compressed is tighter, and elastic force is bigger, and buffer function is also bigger.It can be adjusted by the length and insertion depth for adjusting push rod
The size of cushion effect.One end of push rod is fixed on the lower end of contact block by way of being threadedly engaged.The other end of push rod passes through
Spring retainer block and spring body, insertion buffer in the push-rod hole reserved in block body.Push rod is reserved on spring retainer block to insert
Enter hole, primarily serves limitation and the effect of compressed spring.Spring primarily serves the effect of buffering and damping.Contact block can be passed through
Retreat, drive push rod along buffering block body on push-rod hole retreat, after contact block is contacted with spring retainer block, contact block after
Continuous to retreat, spring retainer block compressed spring makes spring be in compressive state.
Further, as shown in Fig. 2,3 and 5, the positioning limiting fixator includes: first boss 23, second boss 24, adjustment portion
22 and through-Penetration portion 21.One end of the through-Penetration portion 21 is equipped with adjustment portion 22, and the through-Penetration portion 21 is equipped with the first boss 23
With the second boss 24.The adjustment portion 22 is used to adjust the connection depth of the positioning limiting fixator Yu the push rod 28.?
When the through-Penetration portion 21 runs through the pedestal 1 by the first through hole 11, the first boss 23 is located at the one of the pedestal 1
Side, the second boss 24 are located at the other side of the pedestal 1, are bonded position with limit the through-Penetration portion 21 and the pedestal 1
It sets.
Further, the first boss 23 and the second boss 24 are annular cylinder, with the through-Penetration portion set
It connects.
In practical applications, the diameter of first boss and second boss compared with through-Penetration portion can big 1mm, to facilitate and through-Penetration portion set
It connects.First boss and second boss can be linked together with through-Penetration portion by carbon dioxide gas arc welding after socket.
The contact block 27 is cone shape, is vertically arranged with the push rod, and the material of the contact block is rubber material.
The link block 3 is square block, and the link block 3 is equipped with bolt hole, and the link block 3 is logical by the bolt
Hole is fixed with the Inner bolt holes bolt in the vertical parts of the pedestal 1, and the first through hole is arranged in the link block 3
The left and right sides, and be vertically arranged with the end face of the vertical parts of the pedestal 1.
The side block blocks 4 are equipped with countersunk head screw hole, and the side block blocks 4 pass through the countersunk head screw hole and the link block
3 are bolted, and the material of the side block blocks 4 is nylon material.
In practical applications, settable 2 transfer blocks 3 primarily serve the effect of connection pedestal 1 and nylon side block blocks 4.
One end of transfer block 3 is fixed on pedestal 1 by 2 hexagon socket head cap screws.The other end of transfer block 3 by 2 countersunk head screws with
Side block blocks 4 link together.Settable 2 side block blocks 4, the top of transfer block 3 is fixed on by countersunk head screw, and it is slow to play protection
The effect for rushing device 2 avoids fixture scene soldering turret welding gun etc. from encountering buffer 2.When slide unit proceeds to certain phase, side block blocks 4
It is contacted with limited block 5, the contact block of buffer 2 is bonded with the limit hole of limited block 5 at this time, and slide unit sliding stops.
As it can be seen that the utility model provides a kind of limit damper, by increasing buffer, limited block is enable to cross buffer
Slow down impact and vibration, to improve limit accuracy, it is in use to solve the general assembly station clamp that existing automobile assembly uses, due to
The problem of cylinder power is larger larger to the impact force of limited block, easily reduces the positioning accuracy of limited block and service life, energy
