Abstract

A wireless electronic balance tester used for measuring synchronization points and balance of two objects is characterized in that a left electronic timing stopwatch and a right electronic timing stopwatch are integrally arranged, a left timing switch signal receiver is arranged in the left electronic timing stopwatch, and a right timing switch signal receiver is arranged in the right electronic timing stopwatch; a left straight oscillating bar trigger microswitch and a left timing switch signal generator are fixed at the left end of a lower roller, and the left timing switch signal receiver is electrically connected with a timing key circuit of the left electronic timing stopwatch; a right straight oscillating bar trigger microswitch and a right timing switch signal generator are fixed at the right end of the lower roller, and the right timing switch signal receiver is electrically connected with a timing key circuit of the right electronic timing stopwatch; and a public resetting key, a public mode selection key and a public starting and stopping key are arranged in key circuits of the left electronic timing stopwatch and the right electronic timing stopwatch.

Description

Wireless electron balance performance monitor

Technical field

The present invention relates to a kind of balance test device, a particularly wireless electron balance performance monitor, its pressure roller synchronous pressing, synchronous operation of double hydraulic cylinder dumper etc. being mainly used in survey aircraft undercarriage, ship hatchcover, the fork truck arm of force, the excavator arm of force, the wheeled crane arm of force, guided missile mobile launching vehicle lifting mechanism, the bull-dozer arm of force, industrial production need to be looked for two synchronous point and balances between object.

Background technology

Pressure roller synchronous pressing in industrial production, as: carbon steel, stainless-steel cold-rolling unit be according to technology controlling and process needs, is furnished with the pressure roller of a greater number completely, has been used for the start and stop operation of threading and processing line to control.In the time that pressure roller is depressed, require pressure roller two ends to want synchronous pressure by supreme, lower roll surface, otherwise owing to depressing force unbalance, can cause band steel unbalance stress and produce the stopping accidents such as steel band fold or strip running deviation, conventional practice is to press and test the pressure balance that regulates pressure roller both sides with pressure-sensitive paper, but the pressing speed of pressure roller cannot accurately be measured, its adjustment means are simple, the adjusting time is long, degree of regulation is extremely low and depend on adjustment personnel experience, because pressure roller pressing speed and pressure imbalance cause thin gauge strip to press fold in porch, heap steel and sideslip accident often occur, in the time that causing coiling machine to batch due to pressing speed imbalance, outlet section produces band steel heap steel and coil of strip bleeding edge defect.In addition, pressure roller uses for a long time under non-equilibrium state, and device framework, mechanical seal and home roll roll surface have been caused to wearing and tearing, has reduced the service life of functions of the equipments precision and pressure roller.

Summary of the invention

In order to overcome above-mentioned defect, the invention provides a kind of wireless electron balance performance monitor, it has: is easy to carry, simple to operation, be convenient to detect, do not need the advantage of complex device.

The technical scheme that the present invention solves its technical problem is:

A kind of wireless electron balance performance monitor, it comprises top roll, lower roll, left time switch signal generator, left timing electronic stopclock, right time switch signal generator, right time switch signal receiver, left time switch signal receiver, left straight fork fine motion trigger switch, right straight fork fine motion trigger switch, right electric time-keeping stopwatch, common reset key, commonality schemata options button, public startup stop key, is characterized in that: the left electric time-keeping stopwatch that two one are set, right electric time-keeping stopwatch arranges left time switch signal receiver in left electric time-keeping stopwatch, and right time switch signal receiver is set in right electric time-keeping stopwatch, at the fixing left straight fork fine motion trigger switch of left end of lower roll, left time switch signal generator, left time switch signal receiver is electrically connected with the timing key circuit of left electric time-keeping stopwatch, at the fixing right straight fork fine motion trigger switch of right-hand member of lower roll, right time switch signal generator, right time switch signal receiver is electrically connected with the timing key circuit of right electric time-keeping stopwatch, in the key circuit of left electric time-keeping stopwatch and right electric time-keeping stopwatch, common reset key is set, commonality schemata options button, public startup stop key.

When use, by fork fine motion trigger switch that an is straight left side for wireless electron balance performance monitor, right straight fork fine motion trigger switch is separately fixed at a left side for pressure roller, right two ends, pressing common reset key makes two Chronographs return " zero ", pressure roller can trigger left straight fork fine motion trigger switch also by left time switch signal generator time switch signal receiver transmission left time switch triggering signal after depressing, simultaneously, right straight fork fine motion trigger switch is by right time switch signal generator time switch signal receiver transmission to the right time switch triggering signal, make two Chronographs start timing, according to a left side, the time difference that the time switch of right two Chronographs is triggered is carried out pressure roller balanced adjustment, left, the time difference of right two Chronographs is less, balance is better.
