The technological scheme that its technical problem that solves the utility model adopts is: stop that positioning cylinder comprises cylinder body and cylinder cap, described cylinder base is provided with end cap, and inner chamber is provided with piston ring and piston rod, is provided with spring between described piston ring and the described end cap; The hollow inner chamber of described piston rod upper end tool, described inner chamber peripheral wall is connected with buffer, and described buffer inner chamber is provided with the buffer bar of tool piston; The upper end that described piston rod stretches out in described cylinder cap is provided with support, and described top of the trellis established bearing pin and be movably hinged with buffer arm; Described buffer arm lower end presses on described buffer bar; Described cylinder cap sidewall is established the cylinder inner cavity that interface is communicated with described piston ring upper end.
Be provided with damping spring between described buffer bar and the described buffer intracavity bottom, the described buffer inner chamber of described buffer bar piston below is full of hydraulic oil.
Described support one side is provided with guide sleeve and is connected with the guide pillar that is fixed in described cylinder cap; The side supports that described buffer arm is positioned at described bearing pin has torsion spring, and in described support, the other end is butted on described buffer arm sidewall to described torsion spring one end by screw.
Described buffer arm head is provided with the buffering pulley.
The utility model stops positioning cylinder, the buffering pulley of buffer arm head can be exerted pressure to the buffer bar upper end after touching semi-finished product to be processed, damping spring and hydraulic oil by the buffer bar below provide damping function to form cushion effect, buffer bar pops up again after reaching balance, the buffering pulley restores to the original state, semi-finished product to be processed are blocked the location, and production line begins operation processing; After this operation was finished, the sensor on the production line transmitted a working signal to solenoid valve, and solenoid valve is opened through the cylinder inner cavity air feed of cylinder cap sidewall interface to the piston ring upper end, and piston ring drives piston rod behind against the force of the spring and buffer arm moves down in the lump; In folding process, guide pillar has played leading role for support, guarantees that its balance moves.After piston rod and buffer arm integral body moved down, the semi-finished product to be processed of having finished this road manufacturing procedure were able to smoothly by entering next process.Compare than prior art products, that this product has is simple in structure, accurate positioning, respond advantage rapidly, can ensure the smooth and easy and efficient of pipelining, effectively improves the production line effect, reduce the production cost, it is required to be widely used in medium-sized and small enterprises production line automation processed and applied.
Description of drawings
