The test bench has stable performance, fast action speed, wide load adjustable range, fast system response speed and high precision.
Description
Technical field
The present invention relates to the experiment table of ball screw assembly.
Background technology
The at a high speed big at present main dependence on import of load ball screw assembly,, the development level of the big load ball screw assembly, of domestic high speed is compared a certain distance in addition with advanced country, except the factors such as precision of starting material and process equipment, not having perfect test detection means also is a major reason of its development of restriction.Do not have advanced detection means, just be difficult to understand the performance of product, just can not provide for the improvement of product effectively can be for data relatively.Though present domestic ball screw assembly, performance test is comparatively comprehensive, but all when being zero load or underloading, its load situation carries out, the ball screw assembly, range of application of its test is mainly transmission but not transmitted load, can't simulate the operating mode of at a high speed big load ball screw assembly, exactly.
Summary of the invention
The purpose of this invention is to provide a kind of experiment table of testing ball screw assembly, performance under the high-speed overload operating mode.
The ball screw assembly test bed frame that comprises of the present invention, be fixed with a plate and tailgate on the frame, between a plate and tailgate, cylinder lever connecting rod is arranged, pull bar is provided with the column slide plate, one end of column slide plate connects the slide plate lid, the center pit of the column slide plate other end is fastened with ball nut, ball-screw is supported on the tailgate by rolling bearing and bearing holder (housing, cover), one end of ball-screw is twisted and is connect ball nut, the other end of ball-screw is fixed with big belt wheel, and big belt wheel links to each other with the small pulley of device on servomotor by tooth form synchronous belt, is fixed with hydraulic cylinder in a side of a plate, the piston rod of hydraulic cylinder passes through a plate and links to each other piston rod and ball-screw coaxial cable with the slide plate lid.
During work, servomotor drives big belt wheel rotation by tooth form synchronous belt, ball-screw is also rotated, ball nut and slide plate do not rotate, but move forward or backward along pull bar according to the sense of rotation of motor, piston rod is also along with ball nut and moving forward and backward of slide plate and move, and the direction unanimity.Hydraulic jack provides thrust or pulling force, the load when formation ball nut and slide plate move.The size of its load is set the load of ball screw assembly, by HYDRAULIC CONTROL SYSTEM by the threshold values of setting up proportional pressure control valve in the hydraulic system.
Ball screw assembly test bed employing hydraulic jack of the present invention provides load, can accurately simulate ball screw assembly, high-speed overload operating mode, and this experiment table stable performance, quick action, the load adjustable extent is wide, system response time is fast, precision is high.
