Abstract
The utility model relates to a machine for testing mechanical properties of a seat surface of a sofa and soft spring bed mattress, comprising an air pump, an electromagnetic valve, a rapid exhaust valve, an air cylinder, an electronic program controller and a force and displacement measuring mechanism. Signals are inputted into the electronic program controller by a position switch and control the electromagnetic valve enabling a piston rod to move so that the seat surface or the mattress can be continuously loaded by a loading block; the electronic program controller can control the motion frequency of the piston rod according to a programmed program, automatically recording the loading frequency, and automatically stops when the preset loading quantity is reached; meanwhile, the amount of compression is measured by the force and displacement measuring mechanism. The utility model has the advantages of simplified structure, advanced control method, low cost, etc., and can be widely used in the industry of furniture and thereof detection centers.
Description
It is the metering outfit of feature that the utility model relates to gas-electric control method, especially a kind of sofa seat surface and spring mattress pad testing machine for mechanical properties.
According to national sector standard ZB/TY81002.1,81002.2-89, need carry out mechanical property test to the sofa seat surface and the spring mattress pad (being designated hereinafter simply as seat surface and mattress) of software furniture.Test simulation seat surface and mattress are subjected under the condition of repeated load the ability to bear that has when normally using and being accustomed to misapplying.Testing machine is power with pressurized air, as shown in Figure 1, the piston rod 2 top definite shapes of cylinder 1 and the loading blocks 3 of quality are risen, according to the decrement that records fixed falling height, the regulation position of 3 pairs of seat surfaces of loading blocks or mattress 4, with identical frequency, fall as freely falling body, and repeat the loading number of times of standard code.
Present measuring method is: earlier seat surface or mattress are shifted out outside the testing machine, with the resiliometer detector for displacement measuring to the regulation position spiral reinforcing, the force cell reading, its deformational displacement amount is by orthoscopic displacement transducer reading, measuring accuracy is≤0.5mm, record decrement after, seat surface or mattress are moved in the testing machine stipulate the position again, be converted into the loading blocks falling height by the compression value that records, repeatedly seat surface or mattress loaded with loading blocks.Former testing machine loads with conventional pneumatic logic valve control cylinder, and whole atmospheric control is made up of 27 pneumatic in cylinder, two-position-five-way solenoid valve (hereinafter to be referred as solenoid valve), fast-discharge valve, stepping module, AND gate OR-gate group, time-delay valve, vapour-pressure type counter etc.Numerous pneumatic elements causes system complex, reliability is relatively poor, the adjusting difficulty is big, and corresponding cost is also high.
The purpose of this utility model is: not only usefulness electronic process controller control system replaces conventional pneumatic logic valve control system, makes designs simplification widely, and improvement power one displacement measurement mechanism, thereby overcomes the deficiency of original technology.
The technical solution of the utility model is: it comprises loading blocks, air pump, three-major-items, solenoid valve, fast-discharge valve, cylinder etc.Three-major-items are communicated with the P mouth of solenoid valve, the A of solenoid valve, B mouth are communicated with the A mouth of fast-discharge valve, the B mouth of cylinder respectively, the T mouth of fast-discharge valve is communicated with the A mouth of cylinder, two travel switches on the cylinder casing wall are connected with the input end of electronic process controller respectively, and the output terminal of electronic process controller is connected with the electromagnet of solenoid valve.
Below in conjunction with accompanying drawing the utility model is further described.
The fundamental diagram of Fig. 1, testing machine;
The structure principle chart of Fig. 2, the utility model testing machine.
As shown in Figure 2, air pump 5 filters by three-major-items 6(, decompression, mist of oil) pressurized air of discharge dry cleansing, import through the P of solenoid valve 7 mouth, the A of solenoid valve 7, the B mouth connects the A mouth of fast-discharge valve 9 respectively, the B mouth of cylinder 8, the T mouth of fast-discharge valve 9 is communicated with the A mouth of cylinder 8, the to-and-fro movement of control piston bar 12, the sequence of movement of piston rod 12 is: by the travel switch 10 on cylinder 8 casing walls ' be defeated by electronic program system 11 signals, electronic process controller control electromagnetic valve 7, after making the piston rod 12 top loading blocks 3 of cylinder 8 rise to certain position, piston rod 12 signals to travel switch 10, signal to solenoid valve 7 by travel switch 10 again and make fast-discharge valve 9 actions, carry out quick exhaust, piston rod 12 descends fast, and it is seat surface or mattress that loading blocks 3 is fallen measured piece 4(as freely falling body) carry out load test.
Before the test, connecting rod 14 is penetrated in the loading blocks 3, the lower end of connecting rod 14 is connected with demarcation counterweight 13, and the upper end of connecting rod 14 is connected with height vernier calliper 15, constitutes reading device, and measuring accuracy is≤0.1mm.Earlier with after specified force prediction seat surface or the mattress decrement (being displacement), dismounting power one displacement measurement mechanism, press the falling height of displacement conversion loading blocks 3, adjust the position of 3 pairs of seat surfaces of loading blocks or mattress, loading blocks 3 is fallen as freely falling body repeatedly, after reaching the loading stipulated number, carry out power one displacement measurement (increase power) and loading blocks 3 loadings (promptly adjusting falling height) in accordance with regulations repeatedly, the decrement that records with power one displacement then detects whether conformance with standard regulation of different phase seat surface or mattress.
The utility model has the advantages that: firmly a displacement measurement mechanism is measured the pressure of seat surface or mattress The contracting amount can not mobile seat surface or mattress and replace the pneumatic logic valve control system with the electronic process controller control system, not only improve certainty of measurement, and system architecture simplified greatly, control method advanced person, easy to operate, cost is low. Can promote the use of in furniture industry and inspection center thereof.
