Embodiment
In conjunction with Fig. 1, Fig. 2 and Fig. 3, fixedly general frame 4, general frame 4 comprises pedestal 4-1, two symmetrical beam 4-2 and two symmetrical column 4-3, two symmetrical column 4-3 are connected to form integral body with two symmetrical beam 4-2 respectively, and be fixed on pedestal 4-1, while guaranteeing whole equipment work, stability is strong, improves measuring accuracy.Pressure transducer 9 and pulling force sensor 10 use respectively bolted in dynamometry cavity 5-3, two dynamometry cavity 5-3 are symmetricly set on annulus 5-2 both ends of the surface, two top cover 5-1 are separately positioned on dynamometry cavity 5-3 end, top cover 5-1 inwall is close to respectively pressure transducer 9 and pulling force sensor 10, top cover 5-1 other end mounting flange 5-4.Annulus 5-2 is provided with groove, two linking arm 8 one end are semicircle buckle, one end of semicircle buckle is stuck in the groove of annulus 5-2, the other end is connected with location linear slide rail 7, and two buckles are bolted on together again, and linking arm 8 is middle with circular hole, by circular hole, be arranged on two location guides 6, and move along location guide 6, improve stability and the measuring accuracy of equipment, and prevent that gravity from making linking arm 8 deformation effect equipment precisions.The device for measuring force 5 that linking arm 8 is housed is together slided into along locating linear slide rail 7 on fixing general frame 4, two location linear slide rails 7 are separately positioned on the inwall location linear slide rail 7 of two symmetrical beam 4-2 with rule, are convenient for measuring displacement while guaranteeing work.Location linear slide rail 7 is parallel with two location guides 6, and the center of device for measuring force 5, location guide 6, location linear slide rail 7 that guarantees, in same level, prevents that gravity from making linking arm 8 distortion.In the same horizontal line, there are through hole fixed installation electric cylinder 1 and hydraulic cylinder 2 in Qie Guo center at two symmetrical column 4-3 centers, guarantees electric cylinder 1 and hydraulic cylinder 2 the acting on same horizontal line of power when work.Two location linear slide rails 7, two symmetrical beam 4-2, two symmetrical column 4-3 and two location guides 6 be centered close to same plane, guarantee whole stable equipment operation, reduce error.Electric cylinder 1 one end push rod and pressure transducer 9 are fixed together by ring flange 5-4, and hydraulic cylinder 2 one end connect Hydraulic Station 3, and other end push rod and pulling force sensor 10 are fastenedly connected.When electric cylinder 1 applied thrust, top cover 5-1 cannot apply the effect of power to pulling force sensor 10, and pulling force sensor 10 is not worked; When electric cylinder 1 applies pulling force, top cover 5-1 cannot apply the effect of power to pressure transducer 9, and pressure transducer 9 is not worked.
The electric cylinder guide screw lead S=5mm of take is below example, supposes that in electric cylinder, leading screw rotation one circle needs 400 pulses, electric cylinder push rod stroke L0=S/400, i.e. L0=0.0125mm under a pulse.
Thrust process: when servomotor band coding is done thrust transmission in electric cylinder, electric cylinder 1 front end promotes ring flange 5-4 and top cover 5-1, the top cover 5-1 sensor 9 that withstands pressure, pressure transducer 9 work, pulling force sensor 10 is not worked, the pressure regulator valve of regulator solution cylinder pressure 2, until the reading of pressure transducer 9 is 1t.The push rod stroke L1=125mm that sets electric cylinder 1, needs 10000 pulses.And by linking arm 8, can read the push rod stroke L2=124.95mm of actual electric cylinder 1.L1 ≠ L2, illustrates that electric cylinder exists error, by increasing umber of pulse to servomotor motor in electric cylinder, make L1=L2, and hydraulic cylinder is without adjustment.Systematic error delta L=L1-L2, i.e. Δ L=0.05mm.Making up so this error required pulse number is Δ L/L0, needs to increase by 4 pulses.That is to say, when electric cylinder, doing thrust when motion, want the electric cylinder 1 push rod 125mm that passes by, need 10004 pulses, thereby realize the error that makes up electric cylinder 1 work, improve system accuracy.
Pulling force process: when servomotor band coding is done pulling force transmission in electric cylinder, pressure transducer 9 is not worked, pulling force sensor 10 work, the pressure regulator valve of regulator solution cylinder pressure 2, until the reading of pulling force sensor 10 is 1t.The push rod stroke L1=125mm that sets electric cylinder 1, needs 10000 pulses.And by linking arm 8, can read the push rod stroke L2=124.9625mm of actual electric cylinder 1.L1 ≠ L2, illustrates that electric cylinder exists error, by increasing umber of pulse to servomotor motor in electric cylinder, make L1=L2, and hydraulic cylinder is without adjustment.Systematic error delta L=L1-L2, i.e. Δ L=0.0375mm.Making up so this error required pulse number is Δ L/L0, needs to increase by 3 pulses.That is to say, when electric cylinder, doing pulling force when motion, want the electric cylinder 1 push rod 125mm that passes by, need 10003 pulses, thereby realize the error that makes up electric cylinder 1 work, improve system accuracy.
