Stop positioning cylinder

Technical field

The utility model relates to a kind of product cylinder manufacturing technology field, especially refers to the buffer positioning structure of piston rod end.

Background technique

In the industrialization automatic production line, whether half-finished accurate location to be processed will directly have influence on manufacturing efficiency and processing and assembling quality.Comparatively common positioning device is to select position limit switch for use at present; it is by being triggered back starting electrical machinery action by workpiece; enforcement is to half-finished location that stops to be processed; because the cause that medium tache is numerous and the position limit switch hysteresis is big; this type of device needs to shut down and proofread and correct again the location after using a period of time, to guarantee the normal operation operation of production line.So there be defective and the deficiency that positioning error is big, speed of response is slow.For this reason, people expect to invent a kind of accurate positioning, response stops that rapidly the positioning cylinder product comes out, and to ensure the smooth and easy and efficient of pipelining, improve the production line effect, reduce the production cost.

The model utility content

The technical problems to be solved in the utility model is to overcome defective that positioning error is big, speed of response is slow and the deficiency that prior art products exists, provide a kind of accurate positioning, response to stop the positioning cylinder product rapidly to society, to ensure the smooth and easy and efficient of pipelining, improve the production line effect, reduce the production cost.

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.

Embodiment

As shown in Figure 1, the utility model stops positioning cylinder, comprises cylinder body 1 and cylinder cap 6, described cylinder body 1 bottom is provided with end cap 2, inner chamber is provided with piston ring 5 and piston rod 9, and described piston ring 5 is fixed in described piston rod 9 ends by nut 21, is provided with spring 4 between described piston ring 5 and the described end cap 2; Described cylinder body 1 sidewall is provided with installs through hole 3, and described cylinder cap 6 flanges are provided with fixed hole 7; The hollow inner chamber 23 of described piston rod 9 upper end tools, described inner chamber 23 peripheral wall are connected with buffer 18, described buffer 18 inner chambers are provided with the buffer bar 17 of tool piston 22, be provided with damping spring 19 between described buffer bar 17 and described buffer 18 intracavity bottoms, described buffer 18 inner chambers of described buffer bar 17 pistons 22 belows are full of hydraulic oil 20; The upper end that described piston rod 9 stretches out in described cylinder cap 6 is provided with and connects support 10, described support 10 1 sides are provided with guide sleeve 11 and are connected with the guide pillar 8 that is fixed in described cylinder cap 6, the top is established bearing pin 14 and is movably hinged with buffer arm 12, described buffer arm 12 heads are provided with buffering pulley 13, and its lower end presses on described buffer bar 17 upper ends; The side supports that described buffer arm 12 is positioned at described bearing pin 14 has torsion spring 15, and described torsion spring 15 1 ends are fixed in described support 10 by screw 16, and the other end is butted on described buffer arm 12 sidewalls; Described cylinder cap 6 sidewalls are established cylinder 1 inner chamber that interface 24 is communicated with described piston ring 5 upper ends.

Continue in conjunction with the accompanying drawings the working principle of summary the utility model product below.Being chosen in cylinder cap 6 fixed holes 7 of the utility model product or cylinder body 1 sidewall according to the situation of production line support installs through hole 3 and installs and fixes this product.During work, when the place ahead remains to be processed semi-finished product and comes, at first touch the buffering pulley 13 of buffer arm 12 heads of this product, buffer arm 12 is around bearing pin 14 swings, its the other end is exerted pressure to buffer bar 17 upper ends, and buffer bar 17 moves down under damping spring 19 and hydraulic oil 20 damping functions, makes 13 pairs of semi-finished product to be processed of buffering pulley form a cushion effect, buffer bar 17 pops up again after reaching balance, and buffering pulley 13 restores to the original state.This moment, semi-finished product to be processed were stopped the location by this product, and production line begins operation processing; After this operation is finished, sensor on the production line transmits a working signal to solenoid valve, solenoid valve is opened through the cylinder 1 inner chamber air feed of cylinder cap 6 sidewall interfaces 24 to piston ring 5 upper ends, and piston ring 5 drives piston rod 9 after overcoming spring 4 resistances and buffer arm 12 moves down in the lump; In folding process, guide pillar 8 has played leading role for support 10, guarantees that its balance moves.After piston rod 9 and buffer arm 12 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.After semi-finished product to be processed passed through, sensor transmitted a silence signal to solenoid valve, and solenoid valve disconnects operating air pressure, and piston ring 5 moves in the lump driving piston rod 9 and buffer arm 12 under spring 4 effects, returns back to the reset condition that stops the location.
