Description
Technical field
The utility model belongs to the pick-up unit field, especially relates to a kind of device that is used to measure the suction and discharge valve pad thickness on the refrigeration compressor.
Background technology
In daily life, refrigerator has become the living electric apparatus of the indispensability of people's modernization life.People have proposed increasingly high requirement to electrical equipment efficient, energy-conservation in the use of electrical equipment.Refrigerator manufacturer is for satisfying society and customer demand, to the heart of refrigerator--and the technical requirement of compressor low energy consumption, high effect improves year by year.For addressing this problem, increasingly high to the dimension precision requirement of the suction and discharge valve pad thickness in the compressor (assembling back), be one group of thickness by to differ 0.025mm originally be one group of thickness to differing 0.015mm after the heavy duty detergent compressor assembles.How solving freezer compressor suction and discharge valve pad assembling thickness measure problem, is the urgent at present problem that solves.
At first introduce the effect of suction and discharge valve pad:
1, sealing-guarantee that the gas that cylinder piston is pressed into does not leak, thus compressor efficiency improved.
2, the gas that is pressed into of efficient energy-saving property-guarantee cylinder piston can be pressed into high-pressure chamber near 100%, thus the validity of doing work when improving compressor operating, conservation of power consumption.
Thereby if the suction and discharge valve pad plays effect efficiently; To confirm that the thickness of required valve plate pad matches installation according to the physical size after the cylinder body assembling (cumulative errors after all associated components processing, the assembling) during assembling, remedy processing, the assembly error of other part.Need the valve plate pad is carried out thickness measure, grouping under the mounting condition apolegamy when being convenient to assemble for this reason.
The thickness of the airtight valve plate pad of freezer compressor suction requires in pad gross area scope, to apply under the pressure of 2250KG, and the spacer thickness scope is 0.205-0.555mm, and grouping unit is 0.015mm.The domestic before measurement to this type of pad adopts gas to exert pressure, and applied pressure is 80Kg, has only applied the power of assembling pressure requirement (2250Kg) 3.55%, passes through ratiometric conversion again, and spacer thickness of measuring and practical set required thickness error are very big.Cause freezer compressor quality problems more (noise big, effect at the bottom of), the world level of efficient, energy-conservation, the low noise in the time of can't guaranteeing compressor operating makes the compressor of part producer be in the present situation that inferior quality, height are reprocessed always.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, emulation property is strong, measuring accuracy is high air valve mat thickness pick-up unit.
The technical scheme of the utility model is: a kind of air valve mat thickness pick-up unit, comprise support, support, hydraulic cylinder, jig, pressure head, displacement transducer, PLC regulator control system and oil pump, and support is fixed on the support; Hydraulic cylinder is fixed on the support; The end that hydraulic cylinder has a piston rod down, hydraulic cylinder is connected with oil pump, the piston rod of hydraulic cylinder is provided with pressure head; The pressure head bottom is provided with displacement transducer; Displacement transducer is connected with the PLC regulator control system, and jig is fixed on the support of pressure head below, and jig is corresponding with the position of pressure head.
Said oil pump is provided with pressure regulator valve.
Advantage and the good effect that the utlity model has are: the utility model is simple in structure, adjustable in pressure, and usable range is wide, can accurately measure the spacer thickness under the confined state, and error is little.

Embodiment
As shown in Figure 1, a kind of air valve mat thickness of the utility model pick-up unit comprises support 1, support 2, hydraulic cylinder 3, jig 4, pressure head 5, displacement transducer 6, PLC regulator control system and oil pump; Support 2 is fixed on the support 1, and hydraulic cylinder 3 is fixed on the support 2, and the end that hydraulic cylinder 3 has a piston rod down; Hydraulic cylinder 3 is connected with oil pump; The piston rod of hydraulic cylinder 3 is provided with pressure head 5, and pressure head 5 bottoms are provided with displacement transducer 6, and displacement transducer 6 is connected with the PLC regulator control system; Jig 4 is fixed on the support 1 of pressure head 5 belows, and jig 4 is corresponding with the position of pressure head 5.Also be provided with pressure regulator valve on the said oil pump.
The course of work of this instance: regulate before using with oil pump that hydraulic cylinder 3 is connected on pressure regulator valve, setting pressure head 5 downward applied pressures are 2250KG.Move downward through the piston rod on the oil pump control hydraulic cylinder 3 then, thereby drive pressure head 5 moves downward, and pressure head 5 is closely contacted with jig 4, measures distance through displacement transducer 6 signal feedback is arrived the PLC regulator control system, setting at this moment, measured thickness is zero.
During use, air valve pad to be determined is placed on the jig 4, presses down through oil pump control pressure head 5, be depressed into the bottom after, through displacement transducer 6 measure distance with signal feedback to the PLC regulator control system, can obtain the air valve pad in the thickness value that applies under the 2250KG pressure.The air valve mat thickness that records needs in the 0.205-0.555mm scope, not this scope be substandard product, the error with 0.015mm is that a scope is divided into groups the air valve pad in this scope then.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
