Abstract
The invention discloses a ball screw pair experimental bench, comprising a stand. A head plate and a tail plate are fixed on the stand, a connecting tie bar is arranged between the head plate and the tail plate, the tie bar is provided with a cylindrical sliding plate, one end of the cylindrical sliding plate is connected with a sliding plate cover, a ball nut is fastened in a central hole of the other end of the cylindrical sliding plate, a ball screw is supported on the tail plate by a rolling bearing and a bearing housing, the ball nut is screwed at one end of the ball screw, a large belt wheel is fixed at the other end of the ball screw and is connected with a small belt wheel arranged on a servo motor by a synchronous tooth belt, a hydraulic cylinder is fixed at one side of the head plate, and a piston rod coaxial with the ball screw is connected with the sliding plate cover through the head plate. When the ball screw is driven by the servo motor to rotate and drives the ball nut to axially move forwards or backwards, the sliding plate and the piston rod move along with the ball nut, and the load of the ball screw can be regulated by regulating the pressure of a hydraulic oil cylinder. The experimental bench has stable performance, high operation speed, wide adjustable range of the load, high speed of system response 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 performance of products, just the data that effectively can supply comparison can not be provided for the improvement of product.Though present domestic ball screw assembly, performance test is comparatively comprehensive; But all, its load situation carries out when being zero load or underloading; 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 is 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, and an end of column slide plate connects the slide plate lid, and the center pit of the column slide plate other end is fastened with ball nut; Ball-screw is supported on the tailgate through rolling bearing and bearing holder (housing, cover), and an end of ball-screw is twisted and connect ball nut, and the other end of ball-screw is fixed with big belt wheel; Big belt wheel links to each other with the small pulley of device on servomotor through tooth form synchronous belt; Side at a plate is fixed with hydraulic cylinder, and 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 through tooth form synchronous belt; Ball-screw is also rotated, and 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 also moves along with ball nut and moving forward and backward of slide plate, and direction is consistent.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 through 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.
