Description
Technical field
The present invention relates to a kind of sensor detecting, especially a kind of correction pressure sensor comparison force measuring machine.
Background technique
China transducer market is increasing, and especially tension-compression sensor yield increases rapidly, carries out in tension-compression sensor
Production and when factory testing, needs to carry out sensor the comparison with proof force, compares the range, linear and repeat of sensor
Property, the producer for producing sensor at present is mainly to use proof force machine to the detection and measurement of above-mentioned parameter, and detection speed is slow, in this way
Directly affect the production efficiency of sensor, if for factory testing be further added by proof force machine directly increase again invest at
This, it is therefore desirable to a kind of detection device of simple and fast is proposed to solve the problems, such as this.
Summary of the invention
To solve the above problems, it is an object of the invention to provide a kind of correction pressure sensor comparison force measuring machine, including it is upper
Pressing plate, lower plate, screw rod, hydraulic supporting plate, hydraulic cylinder, oilhole, set screw, pallet, deck, standard transducer, master meter,
Instrument is compared, sensor, pedestal are tested.The top board and lower plate are set as square steel plate, are connected by four screw rods,
The screw rod with pedestal consolidation by being placed on the ground.The hydraulic support is arranged among top board and lower plate, passes through
Screw rod positioning height.The centre of hydraulic supporting plate is arranged in by set screw for the hydraulic cylinder, and card is provided below in the pallet
Seat, is located on the hydraulic column of hydraulic cylinder, the standard transducer is fixed on the lower surface of top board, and in stress by deck
The heart will be aligned with the center of hydraulic cylinder and pallet.The upper table of top board is placed on after the master meter and comparison instrument superposition
Face, the standard transducer are connected with master meter by signal wire, and the tested sensor is set to above pallet, and stress
Center is aligned with standard transducer center of effort, and the tested sensor is connected with comparison instrument also by signal wire.
The present invention has the advantages that structure is simple, easy to operate and speed is fast, can rapidly carry out to tested sensor each
The test of item parameter ensure that the quality of tested sensor without being tested on proof force machine, and improve speed,
Detection device investment is saved, application and popularization value is big.
Detailed description of the invention Fig. 1 is structural schematic diagram of the invention

Specific embodiment
With reference to the accompanying drawings of the specification 1, the present invention is described in more detail.
A kind of correction pressure sensor as shown in Fig. 1 comparison force measuring machine, including top board 1, lower plate 2, screw rod
3, hydraulic supporting plate 4, hydraulic cylinder 5, oilhole 6, set screw 7, pallet 8, deck 9, standard transducer 10, master meter 11, comparison
Instrument 12 is tested sensor 13, pedestal 14.The top board 1 and lower plate 2 are set as square steel plate, pass through four screw rods 3
Connection, the screw rod 3 with the consolidation of pedestal 14 by being placed on the ground.The hydraulic support 4 is arranged in top board 1 and lower plate
Among 2, pass through 3 positioning height of screw rod.The centre of hydraulic supporting plate 4, the support are arranged in by set screw 7 for the hydraulic cylinder 5
Deck 9 is provided below in disk 8, is located on the hydraulic column of hydraulic cylinder 5 by deck 9, and the standard transducer 10 is fixed on
The lower surface of pressing plate 1, and center of effort will be aligned with the center of hydraulic cylinder 5 and pallet 8.The master meter 11 and comparison instrument
Table 12 is placed on the upper surface of top board 1 after being superimposed, the standard transducer 10 is connected with master meter 11 by signal wire, institute
It states tested sensor 13 to be set to above pallet, and center of effort is aligned with 10 center of effort of standard transducer, the tested biography
Sensor 13 is connected with comparison instrument 12 also by signal wire.
1 pair of course of work of the invention is described further with reference to the accompanying drawing:
In the sensitivity for carrying out sensor, when linear and repeat type is detected, by tested sensor 13 and it is placed into support
On disk 8, and center of effort is aligned with 10 center of effort of standard transducer.Then by the signaling interface of tested sensor 13 with it is right
It is connected than instrument 12 by signal wire.Then it is pressed by oilhole 6 to hydraulic cylinder 5, pallet 8 is driven to move upwards, passed when tested
When sensor 13 contacts with standard transducer 10 and generates interaction force, master meter 11 and comparison instrument 12 will be generated
Signal is shown, the parameter of tested sensor 13 is detected by comparing, to detect the performance of tested sensor 13, detection is finished
Heel row removes hydraulic oil, and making tested sensor 13, also standard transducer 10 unloads power disengaging, removes tested sensor 13.
The above is only preferred embodiment of the invention, it is noted that those skilled in the art, not
Under the premise of being detached from the invention design, some similar deformation and improvement can be made, these also should be regarded as the present invention
Protection scope within.
