Abstract
The utility model discloses a calibrating furnace for a high and middle-temperature dynamometric sensor which is test equipment used for testing force energy parameters under normal temperature. The utility model can simulate specific working environment, heats, loads and calibrates high and middle temperature dynamometric sensors, and then, the utility model uses the sensors to directly test external force and improves the test accuracy under the high and middle temperature. The difference of the utility model from a general heating furnace is that a furnace cover and a furnace bottom are respectively provided with a plunger piston which is limited by a guide sleeve which is compacted and fixed by a gland.
Description
The utility model is a kind of medium and high temperature force sensor demarcating stove, and it belongs in the Stress analysis from test result technical field, non-normal temperature exert oneself can parameter testing the calibration facility of part.
At present in the proof stress technology under middle hot conditions, what usually adopted is by surveying component stress, then being converted into the indirect force measuring method of tested external force again, because rising along with temperature, and cause the thermal output error of variation of variation, the measured material elasticity coefficient of gauge factor, the stochastic error that also has the technical elements such as stickup, welding of the discreteness of the every performance index of strainometer and strainometer to cause, therefore measuring accuracy is relatively poor, can not guarantee the distribution value amount of test data.
The utility model purpose is: a kind of force sensor demarcating stove that can simulate working environment under the medium and high temperature is provided, under the constant temperature in stove force cell is loaded demarcation.
According to the calibration request of middle high temperature side force transducer, the demarcation stove of the utility model design, energy nominal pressure sensor, pulling force sensor.This stove is the same with general heating furnace, is made up of shell, insulation material, heating element and loading section thereof.Shell connects into whole form with bolt with body of heater, bell and fire door by furnace bottom, loading thermal insulating filling, furnace lining and heating plate in stove can heat, different is respectively to open a circular hole on bell and furnace bottom, in circular hole, load onto plunger, plunger can be up and down, and is spacing with guide pin bushing between plunger and bell and the furnace bottom, seals with asbestos rope between guide pin bushing and the plunger, gland is the sealing of guide pin bushing and asbestos rope, and gland compresses guide pin bushing and asbestos rope and uses bolt.Do the upper end of plunger there emerged a step, makes plunger spacing with step when inoperative.Have two apertures on the bell, pass test lead and temperature element lead respectively.
When using this stove nominal pressure sensing, be placed on the base of the carrier head of Material Testing Machine demarcating stove, install sensor and backing plate, testing machine directly is added in power on the sensor by plunger face, backing plate up and down, and body of heater does not stress.
Demarcate stove when demarcating pulling force sensor, changing the center has the hole, probes into the plunger that a head has the external thread pull bar from the hole, sensor has internal thread, with its one that is threaded with upper and lower two rod heads, the base of the carrier head of testing machine clamps pull bar, testing machine directly is added in pulling force on the sensor by last lower link, and body of heater does not stress.
The utility model is simple in structure, operation, demarcate conveniently, and the sensor that uses this stove to demarcate can directly be measured external force, has improved the measuring accuracy under the middle hot conditions.
Fig. 1 is the utility model nominal pressure furnace structure front view.
Fig. 2 is for demarcating the piston structure front view that has pull bar that pulling force sensor is used.
For sets forth in detail project organization of the present utility model and using method, illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, the shell of this stove is with bolt body of heater 9, bell 3 and fire door 12 to be connected on furnace bottom 1, and fire door 12 cooperates tight with body of heater 9, can also arbitrarily take off.Fill up thermal insulating filling 8 between framework 5 and the body of heater 9, heating plate 6 is divided into four, body of heater 9 interior three, fire door 12 lastblocks, every all is that the resistance wire that will pass ceramic pipe is fixed on the steel plate, and the furnace lining 7 that utilizes compressed asbestos sheet to make again puts together on together, is fixed on the framework 5, resistance wire with every block of plate after the assembling welds, and can heat.Loading section is to load onto guide pin bushing 2 and plunger 10 at bell 3 and furnace bottom 11, and with asbestos paper 4 sealing, gland 1 compresses guide pin bushing 2 and asbestos rope 4 and uses bolt, can load between guide pin bushing 2 and the plunger 10.
To demarcate when using this stove nominal pressure sensor on the base of the carrier head that stove is placed on Material Testing Machine, open fire door 12, install sensor and backing plate, the test lead of sensor and temperature element lead are passed two apertures on the gland 3 respectively, be connected with control box with strainmeter respectively then, can demarcate.(generally be according to sensor working temperature and load condition at the scene, determine good temperature and load range earlier, again temperature and load are demarcated respectively).
When demarcating pulling force sensor, take off plunger 10, change the plunger 14 that has pull bar 13 and get final product.
The heating plate of this demarcation stove is manufactured with resistance wire, and heating-up temperature generally is no more than 450 °.If demarcate the temperature that stove is had relatively high expectations, heating element also can make graphite rod into and suitably strengthen heat-insulation layer, heating-up temperature can be brought up to 1200 °.
Claims (3)
1, middle high temperature side force sensor caliberating stove, furnace bottom is connected to integral body with bolt with body of heater, bell and fire door, in stove, load thermal insulating filling, furnace lining and heating plate, it is characterized in that respectively adorning on furnace bottom and the bell plunger, plunger is spacing with guide pin bushing, with the asbestos rope sealing, gland is fixed guide pin bushing and asbestos rope between guide pin bushing and the plunger.
2, the demarcation stove of middle high temperature side force transducer, furnace bottom is connected to integral body with bolt body of heater, bell and fire door, in stove, load thermal insulating filling, furnace lining and heating plate, it is characterized in that respectively adorning on furnace bottom and the bell plunger of a center drilling, plunger is spacing with guide pin bushing, be fixed with asbestos rope between guide pin bushing and the plunger, probe into a head at the center drilling place respectively and have externally threaded pull bar.
