Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.Following examples only for illustration of the present invention, and are not used for limiting the scope of the invention.
Figure 1 shows that the decomposition texture schematic diagram of pick-up unit of the present invention, comprising leverage 1, tank body bracing or strutting arrangement 2, ground fixing device 3 and the scale 4 for detecting breakaway force.
Wherein, leverage comprises lever arm 11, for the clip 12 of fixing tank body and the hook 13 for connecting lever arm 11 and ground fixing device.Lever arm 11 is provided with adjustable clip 12.This clip 12 upper shed place is provided with projection 16, projection is provided with the hole 17 passed for securing member, and tank body 5 is through after clip 12, and screwing securing member can fix tank body 5.Meanwhile, lever arm is divided into long-armed 14 and galianconism 15 by clip 12, and one end of long-armed 14 is free end, and the other end is connected with clip 12, and one end of galianconism 15 is connected with clip 12, and the other end is connected with hook 13.Ground fixing device 3 is for being fixed on the annular element 31 on ground, and the hook bend of 13 is connected with the annular element 31 of ground fixing device 3.The junction that clip projection 16 contacts with tank body is smooth, smooth, and clip 12 inner ring can increase buffer gasket, to reduce the wearing and tearing of clip 12 pairs of tank bodies.
Tank body bracing or strutting arrangement 2 comprises backing 21, chassis 23 and connects the link 22 on backing 21 and chassis 23.Backing 21 diameter is slightly smaller than the diameter of can body 53, and the outer wall of backing 21 matches with the inwall of can body 53, and its size is passed as best just with tank body.Backing 21 surface needs smooth, or is increasing buffering spacer or packing ring with surface of contact place at the bottom of tank, to reduce the effect of backing to the shock-produced deformation of tank body.
Scale 4 for detecting breakaway force is placed in immediately below tank body bracing or strutting arrangement 2, to ensure scale 4 uniform stressed.
As shown in Figure 2, first tank body bracing or strutting arrangement 2 is placed in during detection directly over scale 4 near centre position.Secondly, the tank mouth 51 of tested tank body 5 is vertically enclosed within backing 21 down, fixedly tightens with clamp bolt.Then, regulate the number of degrees of scale 4, numeral is set to 0.Finally, the free end long-armed 14 applies pressure, and with reference to kilogram number shown on scale 4, if pressure arrives desired value and tank body does not have significant change, then think that the breakaway force of tank body end cap meets the demands, this product is specification product.When adopting this device to detect tank body, owing to not destroying tank body, therefore factory can adopt this device to carry out the full detection of 100% to finished product, also can inspect by random samples, thus meet the testing requirement of different phase, improve the quality of products.
In the present embodiment, lever arm 11 can be flexibly connected with clip 12, thus is convenient to change corresponding clip according to different tank body 5 sizes.
Hook 13 in the present embodiment also can adopt other version, as long as can close with the matching form of ground fixing device.
In the present embodiment, the backing 21 of tank body bracing or strutting arrangement 2, chassis 23 and the link 22 connecting backing 21 and chassis 23 can be integrated, preferably detachable connection, thus be convenient to change backing 21 and connecting link 22 easily for the tank body without size.
As shown in Figure 3, in the second embodiment, the link be connected with one end of the galianconism 15 of lever arm 11 is elastic force measuring device 13 ', and the opposite side of elastic force measuring device is connected with ground fixing device.In the free end force of long-armed 14 during use, with reference to the numeral that elastic force measuring device 13 ' is upper shown, if pressure arrives desired value and tank body does not have significant change, then think that the breakaway force of tank body end cap meets the demands, namely this product is specification product.And other parts in the present embodiment, change same or similar with the first embodiment can be carried out.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle, can also make some improvement and modification.Such as between long-armed free end and ground, arrange a compression dynamomoter, and then learn the pressure acted on end cap, all these improve and modification also should be considered as within scope.
