The utility model has simple structure, convenient use, accurate detecting results and low cost.
Description
Technical field
The utility model relates to vapour-pressure type tensile test machine technology field, relates to a kind of vapour-pressure type circle battery cap welding tensile test machine in particular.
Background technology
At present, lithium ion battery is used very extensive because of its plurality of advantages, but also there is the shortcoming that security is relatively poor, may explode in lithium ion battery, for addressing this problem, most of producer all is provided with explosion-protection equipment on battery cap, therefore this battery cap constitutes by plural smallclothes, and the connected mode between these smallclothes adopts welding more, so the intensity of welding directly has influence on the explosion-proof performance of battery cap.And present most manufacturer does not all have special welding tensile test machine, can't test battery the weld strength of block, therefore the quality instability of the battery cap of producing is brought potential safety hazard to the user.
Summary of the invention
The utility model is exactly a kind of vapour-pressure type circle battery cap welding tensile test machine that provides in order to address the above problem, and is not only simple in structure, easy to use, and testing result is accurate, and cost is low.
The utility model is to adopt following technical scheme to realize above-mentioned purpose: a kind of vapour-pressure type circle battery cap welding tensile test machine, include base, be located at support and operation valve on the base, it is characterized in that: on this support, be provided with the battery cap anchor clamps, be provided with actuating device of atmospheric pressure on the base below these battery cap anchor clamps, this actuating device of atmospheric pressure is connected with the thimble that can vertically move.
As further specifying of such scheme, described actuating device of atmospheric pressure includes cylinder, the guide pillar that is connected on the base and is connected guide pin bushing on the guide pillar, is connected with the thimble base on this guide pin bushing, and the bottom of this thimble base is connected with the piston of cylinder.
Described thimble base is a slab structure, and this thimble base is provided with the thimble anchor clamps.
Described thimble is the multidiameter structure, and this thimble clamping is in the thimble anchor clamps.
Described cylinder is connected with admission line, and this admission line is provided with rain glass.
Described operation valve is a solenoid valve.
The beneficial effect that the utility model adopts above technical scheme to reach is: the utility model is provided with rain glass and solenoid valve, control the output power of actuating device of atmospheric pressure by the operation of solenoid valve, again by each step electromagnetism block in the barometric reading test process suffered in, not only simple to operate, convenient test, and test result is accurate, with low cost.

Embodiment
For further setting forth the utility model 26S Proteasome Structure and Function, the utility model is elaborated below in conjunction with accompanying drawing and preferred embodiment:
As shown in Figure 1, the utility model discloses a kind of vapour-pressure type circle battery cap welding tensile test machine, include base 1, be located at support 2 and solenoid valve 3 on the base 1, on support 2, be provided with battery cap anchor clamps 4, on the base 1 below these battery cap anchor clamps 4, be provided with actuating device of atmospheric pressure, this actuating device of atmospheric pressure includes the cylinder 5 that is connected on the base 1, guide pillar 6 and be connected guide pin bushing 7 on the guide pillar 6, on this guide pin bushing 7, be connected with thimble base 1, the bottom of this thimble base 1 is connected with the piston of cylinder 5, this thimble base 1 is a slab structure, be provided with thimble anchor clamps 9 at the middle part of this thimble base 1, clamping has thimble 10 on the thimble anchor clamps 9, and this thimble 10 is a multidiameter shape structure.Be connected with admission line 11 on the cylinder 5 of actuating device of atmospheric pressure, on this admission line 11, be provided with rain glass 12.
The utility model is when work, at first change battery cap anchor clamps 4 and the thimble 10 corresponding with tested battery cap 13 models, slowly increase the air pressure of cylinder 5 then by manual solenoid valve 3, thimble 10 is injected inside the explosion-proof ball hole of battery cap 13, up to the block top.When thimble 10 pushes up loam cake,, can calculate the welding pulling force of this battery cap 13 by rain glass 12 peakreading this moment if find the loam cake sealing-off; If there is not sealing-off, then continue pressurization, till its top, top was worn, can calculate the top and put on the pulling force that lid does not still have sealing-off this moment according to the peak value of rain glass 12.
Only one of the utility model preferred embodiment shown in the utility model the foregoing description and the accompanying drawing; can not limit to the utility model with this; under the condition that does not break away from the utility model marrow, any change that those skilled in the art did all belongs to protection domain of the present utility model.
