Description

The limiting pressure value detection device of the seal of battery

Technical field

The utility model relates to mechanical field, is specifically a kind of limiting pressure value detection device of seal of battery.

Background technology

The seal of battery afterbody is the lid of flexible material, also the seal is called to sealing ring or sealing gasket in industry,The seal is by the battery cavities sealing of electrolyte solution is housed, when battery is because the factor such as temperature, shock causes in battery cavitiesPressure while exceeding the limiting pressure value of seal, seal just breaks, so that solution flows out in battery cavities, thereby reducesBattery cavities pressure, prevents battery explosion. As can be seen here, the limiting pressure value of seal must accurately and meet designing requirement,Guarantee safety, therefore need checkout gear to detect the limiting pressure value of seal.

The seal of battery comprises cover plate, circle side flanging, upper projection and a lower projection, and upper projection is fixed on cover plate upper surface,Lower projection is fixed on cover plate lower surface, and cover plate, upper projection, lower projection three's axis is located on the same line, and this is closeSealing is also provided with a centre bore that penetrates into lower projection lower end from upper projection upper end.

The limiting pressure value detection device of the seal of the battery of prior art is all after seal is assembled on battery,Detect cell integrated, as application number be ZL2014205570204 utility model patent, the technology of this patentScheme is clamped battery middle part and sealing and battery afterbody exposes outside fixture exactly, and to the boring of battery middle part, from middle partExert pressure to inside battery in hole, make the seal of battery afterbody quick-fried fall, with detectable limit force value. Said method,What detect in fact is that seal is assembled to the limiting pressure value after battery, but seal is assembled in the process in batteryHave the limiting pressure value that several factors changes seal, as there is solution in operate miss or battery in assembling processAffect the performance of seal, etc. So, be assembled to the limiting pressure after battery iff only detecting seal,Just cannot investigate out is in assembling process, to go wrong or seal itself has problem on earth. It is directly right like this, just to needThe seal of battery just detects itself, but prior art lacks the device that seal itself is detected.

Utility model content

The technical problems to be solved in the utility model is, providing a kind of can detect for battery seal itself merelyThe limiting pressure value detection device of the seal of battery.

Technical solution of the present utility model is, a kind of limiting pressure value detection device of seal of battery is provided, itComprise and detect fixture and pressure pipeline system; Detecting fixture is made up of upper fixture and lower clamp;

Double-screw bolt is established in lower clamp upper end, and lower clamp top end face is provided with pit, and lower clamp is provided with pressurization passageway, the going out of pressurization passagewayMouth is communicated with pit, and the entrance of pressurization passageway is connected with pressure pipeline system;

Upper fixture comprises upper bush, upper jacking block and lower jacking block; Upper bush from top to bottom successively poling have the first relief hole, peaceDress hole and internal thread hole; The aperture of the first relief hole, installing hole and internal thread hole increases progressively from top to bottom; The lower end of upper jacking blockProtruding under face have a thimble, on upper jacking block along being vertically through with the second relief hole; The upper surface of lower jacking block is provided with pressure release hole,Protruding under the lower surface of lower jacking block have a fore-set, and lower jacking block is provided with from penetrating into the 3rd of fore-set bottom face at the bottom of the hole in pressure release hole and lets outPress hole and thimble via hole;

The thimble of upper jacking block passes the thimble via hole of lower jacking block and clamp-ons in the centre bore of seal the side flanging cover of sealIn the bottom of lower jacking block fore-set, upper jacking block and lower jacking block are contained in the installing hole of upper bush and upper end and the installation of upper jacking blockAt the bottom of the hole in hole against; The double-screw bolt of lower clamp screws in the internal thread hole of upper fixture, and seal is contained in lower clamp topIn pit and the outlet of pressurization passageway is blocked.

Respectively from installing, detect and dismantling three steps and set forth the operation principle of this checkout gear.

When installation, the first thimble via hole through lower jacking block by the thimble of upper jacking block, then the side flanging of seal also will upwardThe centre bore of seal is inserted in thimble lower end, then two jacking blocks is inserted in to the installing hole of upper bush, finally by upper bushThe double-screw bolt of internal thread hole and lower clamp screws, and screws in process, and the side flanging of seal overlaps the jacking block fore-set bottom of staying automaticallyAnd seal exports the compacting of lower clamp pit automatically to block pressurization passageway.

When detection, the output device of pressure pipeline system is connected with pressurization passageway entrance as nozzle, open pressue device asAir pump, to the pressurization passageway pressurization of lower clamp, after the pressure in pressurization passageway reaches the limiting pressure value of seal, willSeal explosion, now, the value that is arranged on the Pressure gauge demonstration at nozzle place is exactly the limiting pressure value of seal. SealAfter explosion, pressure can be along the of the second relief hole of the 3rd relief hole of lower jacking block, pressure release hole, upper jacking block, upper bushOne relief hole pressure release.

When dismounting, the upper bush of outwarding winding, pours out upper jacking block and lower jacking block, finally the top from lower jacking block by the thimble of upper jacking blockPin via hole is extracted, and extracts in the process of thimble, and seal, originally along with thimble is upwards walked, is subject to the anti-work of fore-setFirmly, the moment that thimble is extracted, seal be subject to thimble power upwards suddenly disappear remaining fore-set only to downward anti-workFirmly, thus seal also under this reaction force with fore-set automatic trip from.

Known through above analytic process, adopt the limiting pressure value detection device of seal of the battery of above structure and existingTechnology is compared, and has the following advantages.

One, when assembling, only thimble need to be passed to thimble via hole and inserts seal centre bore, then two jacking blocks are put intoSleeve, finally screws upper bush, without the fore-set that the side flanging of seal is inserted in to lower jacking block, simple and quickConvenient; Two, realize the detection of the simple limiting pressure value for seal itself, fill up the blank in industry; Three,When dismounting, only need unscrew upper bush, pour out upper and lower jacking block and extract again thimble, just can make side flanging and the Xia Ding of sealThe fore-set automatic trip of piece is convenient from, unloading process also simple and fast.
