Further, the center section cross section that the power transmission shaft is in contact with both sides adjusting slider is ellipse.
Further, the center section cross section that the power transmission shaft is in contact with both sides adjusting slider is Long Circle.
Further, the Worm Wheel System unit includes being connected with servomotor output end worm screw, nibble with worm screw The worm gear of conjunction, the worm screw is fixed on base by worm bracket.
Further, the worm gear is connected with the end of power transmission shaft constitutes transmission cooperation.
Further, the servomotor drives power transmission shaft to rotate by Worm Wheel System unit, so as to pass Moving axis constantly rotates the distance between change both sides adjusting slider, realizes the regulation to test platform height.
The beneficial effects of the utility model are:
1), servomotor drives power transmission shaft to rotate by Worm Wheel System unit in the utility model so that The adjusting slider of both sides is moved along the inclined-plane of base, and the center section cross section that power transmission shaft is in contact with both sides adjusting slider is set For oval or Long Circle, similar to a cam mechanism, in the rotation process of power transmission shaft constantly adjustment both sides adjusting slider it Between distance so that the height to adjust test platform, reach the function of regulation forcing press lower dead point position.
2), the motion for the oval part synchronous adjustment both sides adjusting slider that the utility model passes through power transmission shaft, and then ensure The horizontal level of workbench, will not produce inclination, it is ensured that machining accuracy during up and down.
3), the utility model rising or falling by test platform, to realize the dynamic compensation of bottom dead centre, it is ensured that processing Precision;The utility model device is arranged at the lower section of forcing press simultaneously, easy for installation, compared in the prior art moving bottom dead centre State compensation mechanism be arranged at PRESS PLUNGER or sliding block nearby for, the influence to forcing press transmission mechanism on test platform subtracts It is small, it is ensured that the present apparatus carries out the reliability and stability of pressure test.
