Electric cylinder is the modular product with servomotor and leading screw integrated design, convert rotatablely moving of servomotor to rectilinear motion, simultaneously with servomotor optimum benefits-precise rotation control, accurately revolution control, accurately moment of torsion control is transformed into-precise speed control, Accurate Position Control, accurately thrust control; Realize the brand-new revolutionary product of high precision rectilinear motion series.Be the best substitute of hydraulic cylinder and cylinder: electric cylinder is replacement liquid cylinder pressure and cylinder fully, and realizes more environmental protection of environment, and more energy-conservation, cleaner advantage is easy to be connected with the PLC dispatch control system, realizes high-accuracy motion control.Electric cylinder needing can be used for the occasion of thrust or pulling force, and range of application is wider.
Electric cylinder needs to carry out the tests such as thrust, pulling force, speed and fatigue after finishing assembling, whether meet designing requirement and request for utilization to check it.Best method of testing is for to apply a constant damping to electric cylinder, to simulate actual operating position.
Have dual mode electric cylinder to be tested the first in the prior art: adopt spring assembly to carry out, spring one end is fixed, the other end is connected with the external part of electric cylinder, with the electric cylinder to-and-fro movement; The second: adopt hydraulic pressure or pneumatic cylinder, the cylinder barrel of hydraulic pressure or pneumatic cylinder is fixed, and piston rod is connected with the external part of electric cylinder, with the electric cylinder to-and-fro movement.First kind of way, along with the elongation of spring length, the pulling force of spring is linear change, and increasing, can not simulate actual operating position, but cheap; The second way, hydraulic pressure or pneumatic cylinder provide pressure by hydraulic pump or air lift pump respectively, and the damping that applies is unstable, is the value of a fluctuation, need to just can carry out the test of different damping by adjusting hydraulic valve, and adjusting operation is complicated, and precision is not high.Most of manufacturer still carries out thrust and tensile test by hydraulic cylinder.
Summary of the invention
The technical problem to be solved in the present invention is: the defective that overcomes electric cylinder measuring technology in the prior art, a kind of electric cylinder pushing and drawing force testing machine is provided, a constant damping can be provided when electric cylinder is tested, can simulate more really actual operating position, so that test structure is more accurate.
The technical solution adopted for the present invention to solve the technical problems is: a kind of electric cylinder pushing and drawing force testing machine, comprise test platform, be provided with holder that the electric cylinder stiff end is installed on the described test platform and with the reciprocating portable plate of electric cylinder external part, sliding seat is installed on the portable plate, the damping brake that damping is provided to portable plate also is installed on the described test platform, described damping brake comprises electromagnetic clutch, reductor and pinion and rack, the tooth bar of described pinion and rack is fixedly connected with portable plate, described gear is installed in the input end of reductor, and electromagnetic clutch is installed in the output terminal of reductor.
For being fit to the electric cylinder of different length, described portable plate is provided with two rows and is used for regulating the threaded hole of spacing between holder and the sliding seat, and sliding seat is fixedly connected with threaded hole by bolt.
Further, on the described test platform rectilinear orbit is installed, described portable plate bottom is equipped with the slide block that cooperates with rectilinear orbit.Rectilinear orbit and slide block are used in conjunction with portable plate are moved in restricted portion.
Further as preferred, described electromagnetic clutch is powder clutch, and described powder clutch is provided with damper regulator.
The invention has the beneficial effects as follows, electric cylinder pushing and drawing force testing machine of the present invention adopts being combined in when testing of electromagnetic clutch and reductor that constant damping is provided, and simulates more really actual operating position, so that test result is more accurate.
