Moreover, the mounting space can be reduced effectively, interference with an embedding position is prevented, and greater convenience is brought to use.

Description

A kind of difunctional pneumatic device

Technical field

The utility model relates to pneumatic means and makes field, refers in particular to a kind of difunctional pneumatic device.

Background technology

At present, development along with process of industrialization, part in industrial products is also just towards the future development of miniaturization, the volume of the nut of for example need installation in industrial production, inlaying is more and more less, manually carry out the installation of such small-sized nut and inlay comparatively difficulty, thereby occurred for adsorbing and eject the pneumatic means of nut.

But, pneumatic means of the prior art is general only realizes ejecting function with standard straight-line cylinder, adsorption function needs external other mechanism just can complete, and structure is comparatively complicated, and volume is large, and cost is higher, cause the wasting of resources, moreover pneumatic means of the prior art easily produces interference with embedding object location, go out the embedding thing mould many, spacing is again little for one, this pneumatic means can not be realized its function that ejects and adsorb.

Summary of the invention

For overcoming the defect having in above-mentioned prior art, the purpose of this utility model is to provide a kind of difunctional pneumatic device, this pneumatic means can be realized adsorption function and ejecting function simultaneously, and simple in structure, reduce installing space, be difficult for embedding object location to produce and interfere, can effectively reduce costs, economize on resources.

For achieving the above object, the technical scheme that the utility model adopts is:

A difunctional pneumatic device, at least includes:

The cylinder barrel of one hollow, the middle part of described cylinder barrel offers an absorption air inlet, and described absorption air inlet is equipped with a vacuum plant outward, and the bottom of described cylinder barrel offers one and ejects air inlet;

One has the axle core of endoporus, described axle core is positioned at cylinder barrel, the upper end of axle core offers several suction holes that lead to endoporus, the middle part of axle core and bottom convex with respectively end face the first bulge loop and the second bulge loop that aforementioned inner wall of cylinder arranges of fitting, the outside of described the first bulge loop and the second bulge loop is all set with sealing ring, position on described axle core between the first bulge loop and the second bulge loop offers a perforate that endoporus is communicated with aforementioned absorption air inlet, and described the second bulge loop is located at the aforementioned air inlet top that ejects;

And a plug, described plug is blocked the opening of cylinder barrel lower end and is compressed the axle core in cylinder barrel.

According to said structure, axle core outside more than described the first bulge loop is arranged with a spring, and the lower end of described spring is propped up and headed on the first bulge loop, and a support top position that heads on cylinder inner wall upper end is propped up in the upper end of described spring.

According to said structure, it is clamped that described cylinder barrel upper end is provided with a suction, the clamped axle core top that is positioned at of described suction.

Compare with conventional art, the beneficial effects of the utility model are:

The utility model, in same cylinder mechanism, utilizes two kinds of gas circuits to realize absorption and ejecting function simultaneously, simple in structure, can effectively reduce cost of manufacture, economize on resources, and can effectively reduce installing space, be difficult for producing and interfering with embedding object location, use more convenient.

Below in conjunction with drawings and the specific embodiments, the utility model is further described:

accompanying drawing explanation:

Fig. 1 is the cross-sectional view of the preferred embodiment of the utility model;

Fig. 2 is the local structure for amplifying schematic diagram of Fig. 1.

the specific embodiment:

As shown in Figure 1 and 2, the utility model relates to a kind of difunctional pneumatic device, and this pneumatic means packing has cylinder barrel 2, an axle core 3 and a plug 8 of a hollow, and the lower ending opening of described cylinder barrel 2 is blocked by plug 8, axle core 3 is positioned at cylinder barrel 2, described plug 8 compression axis cores 3.

The middle part of cylinder barrel 2 and bottom offer respectively an absorption air inlet 5 and and eject air inlet 7, described absorption air inlet 5 and ejecting in the hollow bulb that air inlet 7 all leads to cylinder barrel 2, the external vacuum plant that is connected with of described absorption air inlet 5, it is clamped 21 that the upper end of described cylinder barrel 2 forms a suction, and the below of the suction clamped 21 of described cylinder barrel 2 inwalls is provided with a support top position 22.

The middle part of axle core 3 is provided with endoporus 35, the middle part of axle core 3 and bottom form the first bulge loop 33 and the second bulge loop 34, the end face of described the first bulge loop 33 and the second bulge loop 34 is all close to the inwall setting of cylinder barrel 2, and the outside of the first bulge loop 33 and the second bulge loop 34 is all set with sealing ring 6, to forming sealing with cylinder barrel 2 inwalls.The upper end of axle core 3 offers several suction holes 31 that lead to endoporus 35, and as shown in Figure 2, aforementioned suction clamped 21 is positioned at the top of axle core 3.On axle core 3, between the first bulge loop 33 and the second bulge loop 34, position offers a perforate 32 that is communicated with endoporus 35, and described perforate 32 is communicated with the absorption air inlet 5 on aforementioned cylinder barrel 2.The second bulge loop 34 on axle core 3 is positioned at the top that ejects air inlet 7 on aforementioned cylinder barrel 2.The outer wall of axle core 3 is arranged with a spring 4, and described spring 4 is located between the support top position 31 and the first bulge loop 33 on axle core 3 in cylinder barrel 2, and the upper end of spring 4 is propped up and headed on support top position 31, and the lower end of spring 4 is propped up and headed on the first bulge loop 33.

During this pneumatic means work, vacuum plant extracts the air of 35 li of axle core 3 endoporus by absorption air inlet 5, and then draws the air at clamped 21 places by the suction hole 31 on axle core 3, thereby makes to inhale clamped 21 in vacuum state, can obtain nut 1 by inhaling clamped 21, complete adsorption function; And if the nut 1 being adsorbed on clamped 21 will be ejected, can be to ejecting air inlet 7 ventilations, on axle core 3, the following excircle of the second bulge loop 34 produces air-flow, thereby by impeller-hub core 3 upwards, axle core 3 Compress Springs 4 also eject the nut 1 of inhaling on clamped 21, nut 1 is hightailed inhale clamped 21, complete ejecting function.
