Description
Technical field
The utility model relates to level sensor technical field of processing equipment, is specifically related to a kind of water level sensor of washing machine air-tightness detection tool positioning module.
Background technology
Water level sensor of washing machine is used for the change of sensed water level, and the air pressure produced when its principle is and utilizes water level to rise is delivered on sensor by pipeline, and magnetic core movement change in coil magnetic flux is realized.As the standard universal part of on washing machine, the principle of existing level sensor is all substantially identical, and its theory structure is as follows: divide inner/outer tube by washing machine tub, urceolus has an independent air chamber, aqueous phase in this air chamber and urceolus connects, and keeps water level at grade; The top of air chamber is received on the valve of level sensor by seal tube.When the height of water level in washing machine drum changes, water level in independent air chamber on urceolus also changes thereupon, be sealed in the air pressure to one section of sealing air of sensor diaphragm bottom in urceolus independent air chamber water surface top, O-ring seal flexible pipe, change along with the SEA LEVEL VARIATION in laundry machine barrel.At sensor internal, the diaphragm in sensor is raised by the air pressure that sealing air section provides.Diaphragm in sensor there is a magnetic core support, magnetic core support has a magnetic core, outside magnetic core, be with a coil, magnetic core has one be installed in spring that set screw on housing compresses; When diaphragm is raised, so spring is under pressure and is compressed; When the pressure that diaphragm is lifted to sealing air section and provides equals the elastic force of spring, reach a balance, now magnetic core has a position relative to coil, and coil then can export a frequency values to computer board of washing machine; By above conversion, computer board of washing machine just can judge the water level height of washing machine.
Along with improving constantly of washing machine automaticity, the requirement for all parts of washing machine is also more and more higher.Need constantly to improve, to adapt to the requirement of this change to the equipment of each parts of processing.During as detected level sensor inside impermeability, traditional method employing is manually held level sensor and is then detected, and workload is large, and efficiency is low.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, easy to operate washing machine level sensor air-tightness detection tool positioning module.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of water level sensor of washing machine air-tightness detection tool positioning module, comprise a circular jig, described jig is provided with a circular locating slot, for placing level sensor, described locating slot edge is along the circumferential direction provided with rib, is provided with screw, for stationary positioned mould at described circular locating slot center, described jig side has admission piece standing groove, and described jig is arranged on a crossbeam.Be placed in jig when detecting by level sensor, admission piece is placed in admission piece standing groove, then connects source of the gas and realizes carrying out sealing detection to level sensor.
Described crossbeam is provided with screw, and the screw in this locating slot worn by mistake bolt and jig is fixed on crossbeam by the screw on crossbeam.
Another object of the present invention is to provide a kind of level sensor air-tightness detection tool being provided with above-mentioned positioning module, comprise a testing stand, described testing stand is provided with work top, both sides, described work top front end are connected with angle steel, described angle steel is connected with the first supporting traverse, described first supporting traverse front portion is provided with the second supporting traverse, described first supporting traverse is arranged at intervals with gas-tpe fitting, described gas-tpe fitting one end connects source of the gas by pipeline, the gas-tpe fitting other end is connected with level sensor connector, described second supporting traverse installs jig, for positioning level sensor, during detection, be arranged on respectively in jig by level sensor, by the admission piece of level sensor access level sensor connector, start source of the gas, air feed in level sensor, realizes the air-leakage test of level sensor.
Described second supporting traverse is connected with the first supporting traverse by screw mandrel, these screw mandrel two ends are located in the hole of the second supporting traverse and the first supporting traverse respectively, and the outer end of described screw mandrel is provided with setting nut, spring is provided with between described first supporting traverse and the second supporting traverse, the two ends of spring are separately fixed on the first supporting traverse and the second supporting traverse, by carrying out fastening to setting nut, the spacing between the second supporting traverse and the first supporting traverse can be regulated, the distance between jig and level sensor connector is made to increase or reduce, with the needs that the level sensor adapting to different size detects.
Described second supporting traverse bottom surface is arranged on angle steel, is to support with angle steel.
The beneficial effects of the utility model are: the utility model structure is simple, and reasonable in design, well can locate level sensor, facilitate the carrying out of testing, practicality is good, applied widely, and work efficiency is high.
