Description
Technical field
The utility model relates to a kind of automatic fetching device.
Background technology
In the auto parts and components course of processing, need to use take out device to take out, shift and produce complete workpiece, traditional mode, take out by holder workpiece, shift, but adopt in this way in the process of clamping, fixture and workpiece are easy to skid, and scratch workpiece or workpiece is dropped damage.
For avoiding above-mentioned damage, the mode of current employing is normally bled by air extracting pump and is held workpiece, take out again, shift, well solve the problems referred to above, but due to a lot of workpiece of auto parts and components having several groove not of uniform size or holes, when take out device holds workpiece, these grooves or hole can cause workpiece to get loose from take out device, this is owing to being communicated with extraneous air between take out device with workpiece from groove or hole, causes the suction force of take out device to workpiece to die down.
And for this problem, only have at present and draw position by moving when absorption workpiece, avoid groove or hole, not only extremely bother, and same take out device is not often suitable for different workpiece.
Summary of the invention
The utility model is not enough for prior art, provides a kind of automatic fetching device, it can be drawn, workpiece that transitional surface has different groove or hole, and applied widely, improving production efficiency, reduces workpiece damage degree.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of automatic fetching device, comprise housing, cavity is offered in described housing, described cavity and air extracting pump are interconnected, described housing outer surface offers several groove, a described groove floor offers the one number service hole and No. two through holes that are communicated with described cavity, the seal strip in this one number service hole of movable sealing is provided with at described one number service hole place, described No. two through holes are provided with the rubber diaphragm of these No. two through holes of sealing, described rubber diaphragm is fixedly connected with strut bar towards the side of a described groove, its opposite side is hinged with a pipe link, a described pipe link is supported by back-up block, a described pipe link is hinged with No. two pipe links, described No. two pipe links are connected with described seal strip.
During use, pass through lever principle, when strut bar touches the position not having groove or hole, strut bar pushes up in take out device, a pipe link and the hinged end, one end of rubber diaphragm are up moved, thus the other end of a pipe link is moved down, push seal strip open, air extracting pump can be played a role in this place No. one groove location, hold workpiece; When strut bar extend in the groove of surface of the work or hole, strut bar does not reach workpiece, strut bar keeps original position, now, seal strip seals up one number service hole, ensure that extraneous air is not communicated with the cavity in take out device, can not have influence on other groove location place to the suction force of workpiece, namely each groove is one and independently draws unit, independently provides a suction force to workpiece.
The utility model compared with prior art, there is following beneficial effect: the workpiece that the utility model can be drawn, transitional surface has different groove or hole, simultaneously each groove is one and independently draws unit, be independent of each other each other, draw effective, applied widely, improving production efficiency, reduces workpiece damage degree.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail: see Fig. 1-Fig. 3, a kind of automatic fetching device, comprise housing 1, cavity 11 is offered in described housing 1, described cavity 11 is interconnected with air extracting pump, described housing 1 outside face offers several groove 2, described groove 2 bottom surface offers the one number service hole 21 and No. two through holes 22 that are communicated with described cavity 11, the seal strip 3 in this one number service hole 21 of movable sealing is provided with at described one number service hole 21 place, described No. two through hole 22 places are provided with the rubber diaphragm 4 of these No. two through holes 22 of sealing, described rubber diaphragm 4 is fixedly connected with strut bar 5 towards the side of a described groove 2, its opposite side is hinged with a pipe link 6, a described pipe link 6 is supported by back-up block 7, a described pipe link 6 is hinged with No. two pipe links 8, described No. two pipe links 8 are connected with described seal strip 3.
Limit, described one number service hole 21 is provided with No. two grooves 23, and on described seal strip 3, be provided with the inserted sheet 31 supporting with described No. two grooves 23, described No. two grooves 23 and described inserted sheet 31 interference fit.By arranging No. two grooves 23 and the inserted sheet 31 of interference fit, make the better tightness of a groove 2, thus make take out device to the absorption better effects if of workpiece.
Described back-up block 7 upper end offers the downward open slot of two ends arc 71, and is provided with bracing ring 72 at the two ends of described open slot 71, and a described pipe link 6 is arranged in described open slot 71 through described bracing ring 72.By arranging open slot 71 and bracing ring 72, under the prerequisite that pipe link 6 two ends can swing up and down, a pipe link 6 can not be separated with back-up block 7 and come off, the normal use of assurance device.
During use, pass through lever principle, when strut bar 5 touches the position not having groove or hole, strut bar 5 pushes up in take out device, the hinged end, one end of a pipe link 6 and rubber diaphragm 4 is up moved, thus the other end of a pipe link 6 is moved down, push seal strip 3 open, air extracting pump can be played a role in this place No. one groove 2 position, hold workpiece; When strut bar 5 extend in the groove of surface of the work or hole, strut bar 5 does not reach workpiece, strut bar 5 keeps original position, now, seal strip 3 seals up one number service hole 21, ensure that extraneous air is not communicated with the cavity 11 in take out device, can not have influence on other groove 2 position to the suction force of workpiece, namely each groove 2 is one and independently draws unit, independently provides a suction force to workpiece.
