Embodiment
Do below in conjunction with the accompanying drawing specific embodiments of the invention and to describe in detail:
As shown in Figure 1, this novel damping device airtight test machine comprises frame 5 and water tank 4, on the said frame 5 airtight experimental considerations unit is installed, and said airtight experimental considerations unit comprises operating component 1 and detection components 2;
Said operating component 1 comprises operating component cylinder upper limit switch 11, operating component cylinder 12 that is arranged at operating component cylinder 12 upper ends and the operating component cylinder limit switch 13 that is arranged at operating component cylinder 12 lower ends, and said operating component cylinder 12 is arranged at said frame 5 upper ends; Said detection components 2 comprises detection components frame 21, two detection components cylinders 22, two detection heads 24 and detects part positioning tool 3; Said detection components frame 21 upper ends are connected with said operating component cylinder 12 piston rods; Said two detection components cylinders 22 are arranged at the top of detection components frame 21; The fixing respectively detection head 24 of the piston rod of said two detection components cylinders 22; Said detection part positioning tool 3 is made up of go 31 and location holder 32, and said go 31 is arranged between detection head 24 and the detection components frame 21, said detection components frame 21 bottoms; Said water tank 4 is arranged at the bottom of frame 5, is equipped with in the water tank 4 to detect medium 41.
Said detection head 24 is a spring-loaded check valve.Said detection components frame 21 also is provided with wheel 23, and said frame 5 is provided with the slide rail 51 that cooperates said wheel 23.Said detection components 2 also is provided with tensimeter 25.Said airtight experimental considerations unit is provided with two, is installed in the left one side of something and the right-hand part of frame 5 respectively.
The control of airtight detection time: as shown in Figure 2; In the electric control system of this testing machine, adopt controller digit time, precision can reach 0.1s, regulates pressurize scope 0～99s; Can set by operating personnel according to the kind of product; At present < therefore 15s, can satisfy the airtight detection needs of vibration damper product to product detection time.
The electrical control design: 1. two operating component 1 operations adopt time sharing wheel to start building to do mode; 2. simultaneous mode of working is adopted in two detection components cylinders 22 and two detection head 24 operations in the detection components 2 in each operating component 1; The work of detection head 24 be according to digit time controller setting and the adjusting of respective sensor carry out, electric-control system is opened corresponding electromagnetic valve of gas circuit in testing process inflation detects to part.The electrical principle block diagram is asked for an interview Fig. 2.
