Description
Technical field
The present invention relates to analysing valve control type lead-acid accumulator battery, be specifically related to a kind of pick-up unit of accumulator pole group pressure.
Background technology
Along with developing rapidly of China's accumulator product, in the accumulator manufacture process, especially under utmost point group is manual in the groove process, utmost point group's assembling pressure directly affects the performance of accumulator, this is because the active substance on the chip pole plate is directly to be adsorbed on the grid rib, active substance constantly expands in the charge and discharge process of battery, again owing to be subjected to the effect of gravity, active substance must come off, this just makes the separator paper between the positive/negative plate that certain force of strain must be arranged, and is pressing active substance and is making it difficult drop-off.If the assembling pressure that separator paper is subjected to is too big, though coming off of active substance played very big effect, but may damage pole plate easily and burst battery case, if it is very tight that the AGM dividing plate is pressed, to cause internal density big, inhale the acid amount relatively and reduce, acid and colloid are not easy the bottom of permeation cells, thereby influence the performance of accumulator.In addition, generally the thickness of separator paper all is the thickness that rule of thumb is worth under the theoretical assembling pressure that calculates, and electrode thickness that actual smear comes out and theoretical value have certain deviation, this just makes assembling pressure and standard value that discrepancy is arranged, must influence the performance of battery, therefore, how accurately measure the assembling pressure of accumulator pole group, assembling for accumulator plays crucial effects, invents a kind of device that can measure the battery assembling pressure and then becomes imperative.
Summary of the invention
The object of the present invention is to provide a kind of accumulator pole group pressure electronic detector, can accurately measure the assembling pressure of accumulator, in charge and discharge process, expand and come off, damage pole plate easily and burst the problem that battery case, acid and colloid are not easy to influence bottom the permeation cells usability of battery to solve excessive, the too small and positive active substance that cause of assembling pressure that prior art exists.
The present invention is achieved through the following technical solutions:
A kind of accumulator pole group pressure electronic detector, base support plate two ends are provided with front shoe, the rear fixed plate that is parallel to each other, parallelly again between forward and backward fixed head be provided with pressing plate, push pedal, two guide pillars lay respectively at the both sides of forward and backward fixed head, and are fixedly connected with forward and backward fixed head after crossing pressing plate and push pedal; Pressure transducer places between pressing plate and the push pedal, and one end vertical fixing is in the centre of pressing plate, and the other end contacts with push pedal; Electronic console is connected with pressure transducer, shows the force value of pressure transducer; The rear fixed plate centre is fixed with a feed screw nut, and leading screw one end is connected with crank, and the other end then screws in the feed screw nut, and pushes against push pedal and travel forward.
Optimized technical scheme of the present invention is:
Above-mentioned a kind of accumulator pole group pressure PCU is provided with the linear slide bearing between the through hole of guide pillar and pressing plate, its internal diameter matches with the cylindrical of guide pillar, and its external diameter matches with the internal diameter of pressing plate through hole.Described pressure transducer is provided with the sensor protection piece, prevents the pressure transducer overload.
The forward and backward fixed head outside is provided with reinforcement, and electronic console is between the reinforcement in the front shoe outside.Pressing plate is that multilayer board is built up, can be by number of laminae delete adjusting thickness.
The present invention compared with prior art has following obvious advantage:
The present invention makes in the leading screw precession feed screw nut by shaking crank, and pushes against push pedal and travel forward together, and push pedal can be transferred to pressing plate with thrust by pressure transducer, drives pressing plate and moves towards tested utmost point group.When pressing plate with tested utmost point group by original expansion distance be pressed onto mensuration apart from the time, the displayed value of the electronic console that is connected with pressure transducer is tested utmost point group's assembling pressure.The present invention can accurately detect the assembling pressure of accumulator pole group, can avoid causing that positive active substance expands comes off easily, causes because of assembling pressure is excessive and damage pole plate and burst the phenomenon that battery case, acid and colloid are not easy the permeation cells bottom in charge and discharge process, guarantee the reliable and stable of accumulator property because of assembling pressure is too small.
