Preferably, described the first cylinder be connected cylinder and connect respectively a switching cylinder.
The utility model provides a kind ofly measures the stable gas pressure mechanism of internal gap of hydraulic torque converter because the power of two cylinders is the constant force through calculating, so the high conformity of measured value.With respect to being added in power on the arm of force with the manpower mode by spring, the stability of this mechanism is better, and repeatable accuracy is higher.Need not clamp the pump impeller axle sleeve of fluid torque-converter in addition, put up and get final product, can evade pump impeller shaft and be enclosed within the risk that scratches when measuring.
The device that the utility model provides has overcome the deficiencies in the prior art, and is easy and simple to handle, and the data stability that records is good, high conformity, and repeatable accuracy is high.
Description of drawings
A kind of synoptic diagram of measuring the stable gas pressure mechanism of internal gap of hydraulic torque converter that Fig. 1 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with a preferred embodiment, and cooperate accompanying drawing to be described in detail below.
A kind of stable gas pressure structural scheme of mechanism of measuring internal gap of hydraulic torque converter that Fig. 1 provides for the utility model, described a kind of stable gas pressure mechanism of measuring internal gap of hydraulic torque converter comprises base 11, scroll chuck 3 is contained in base 11 middle parts, and measuring head 1 is equipped with at scroll chuck 3 centers; Lever arm of force 8 is contained in base 11 1 ends by balance pivot 7, and lever arm of force 8 one ends are connected with measuring head 1 bottom by jack-up 5.It is the small cylinder of two different pressures that the first cylinder 10 and the second cylinder 9, the first cylinders 10 and the second cylinder 9 are housed on the lever arm of force 8; Base 11 other ends are equipped with dial gauge display 4.The first cylinder 10 be connected cylinder 9 and connect respectively a switching cylinder 6.
The stable gas pressure method of measuring internal gap of hydraulic torque converter comprises following step:
Step 1: with the center of the turbine of fluid torque-converter to be measured and piston component 2 in measuring head 1 upper end;
Step 2: start the first cylinder 10, the center of at first withstanding turbine and piston component 2, can only be withstood and can not jack-up electronic centigrade scale display 4 zero setting this moment according to the calculating of the first cylinder 10 pressure; The computing method of the first cylinder 10 pressure are as follows:
The first step: first turbine and piston component 2 are weighed, drawing weight is 2.2kgF.
Second step: the cylinder theory is exerted oneself according to formula F=P*A, and wherein A is cylinder piston area (cm
2), P is the operating pressure (kgF/cm of source of the gas
2);
The first cylinder 10 piston diameters are 10mm, its area A=π R
2=0.5
2* 3.14=0.785cm
2
Fixing tentatively respectively when the first cylinder 10 source of the gas operating pressures is 1.6kgF/cm
2And 2.0kgF/cm
2The time, can draw the first cylinder 10 theories and exert oneself and be respectively:
①0.785cm
2*1.6kgF/cm
2＝1.26kgF
②0.785cm
2*2.0kgF/cm
2＝1.57kgF
That is to say that the first cylinder 10 source of the gas working pressure pressure can transfer to 1.6kgF/cm
2～2.0kgF/cm
2, the theory of the first cylinder 10 is exerted oneself and is that 1.26kgF～1.57kgF, this numerical value all are lower than the weight of turbine and the piston component of 2.2kgF so.Can make like this measuring head 1 be close to the turbine endoporus, and can be by jack-up, at this moment 4 zero setting of electronic centigrade scale display.
Step 3: start the second cylinder 9, make the pressure of the second cylinder 9 greater than the gravity of turbine and piston component 2, with turbine and piston component 2 complete jack-up; Calculate appropriate pressure, pressure can not be excessive, can not be whole fluid torque-converter jack-up; The reading that shows on the electronic centigrade scale display 4 at this moment is the internal gap of hydraulic torque converter value; The computing method of pressure are as follows:
The piston diameter of the second cylinder 9 also is 10mm, uses equally formula F=P*A, is 3.0kgF/cm when the second cylinder 9 source of the gas operating pressures are tentative respectively
2And 3.5kgF/cm
2The time, can draw the second cylinder 9 theories and exert oneself and be respectively:
①0.785cm
2*3.0kgF/cm
2＝2.36kgF
②0.785cm
2*3.5kgF/cm
2＝2.75kgF
That is to say that the second cylinder 9 source of the gas working pressure pressure can transfer to 3.0kgF/cm
2～3.5kgF/cm
2The theory of the second cylinder 9 is exerted oneself and is 2.36kgF～2.75kgF so, and this numerical value can have enough power jack-up turbines and piston component 2 greater than the weight 2.2kgF of turbine and piston component, but the general assembly (TW) of torque converter is 6.7kgF, so can be whole fluid torque-converter jack-up.
Step 4: with the first cylinder 10 and the second cylinder 9 repositions, repeatedly measure, its internal clearance value can not change good reproducibility.
The utility model provides a kind ofly measures the stable gas pressure mechanism of internal gap of hydraulic torque converter because the power of two cylinders is the constant force through calculating, so the high conformity of measured value.With respect to being added in power on the arm of force with the manpower mode by spring, the stability of this mechanism is better, and repeatable accuracy is higher.Need not clamp the pump impeller axle sleeve of fluid torque-converter in addition, put up and get final product, can evade pump impeller shaft and be enclosed within the risk that scratches when measuring.
