Summary of the invention
Technical matters to be solved by this invention is to overcome existing parameter testing table six degree of freedom position of platform to be difficult to the accurately difficult problem of convenient adjustment, a kind of highly versatile is provided, can makes things convenient for, accurately adjust the parameter of bogie testing table six degree of freedom position of platform adjusting gear of the position of six degree of freedom platform.
For solving the problems of the technologies described above; The present invention provides a kind of parameter of bogie testing table six degree of freedom position of platform adjusting gear; It is characterized in that: comprise the two hollow lifting jack of rod, hydraulic cylinder hold-down supports, draw push rod assembly, platform web joint and electric hydraulic pump; Electric hydraulic pump provides power source for two hollow lifting jack of rod, and the hollow lifting jack of two rods is a drive unit, draws push rod assembly one end to draw, push work through the driving realization of the hollow lifting jack of two rods; Draw the other end of push rod assembly to be fixedly connected with vertical actuator base platform, two vertical actuator base platforms of each six degree of freedom platform one side are fixedly connected through the platform web joint.
The hollow lifting jack of two rods mainly is made up of urceolus, hollow piston bar and two seal stopper rings, and outer tube inner chamber is divided into two cavitys through the hollow piston bar.
Draw the push rod assembly mainly to comprise and bear nut, hydraulic cylinder cylinder lever connecting rod, middle brace rod, force transmitting board, the connection of hydraulic cylinder cylinder lever connecting rod one end bears nut, and the other end connects middle brace rod, and middle brace rod is fixedly connected force transmitting board.
The present invention has adopted a kind of pair of hollow lifting jack of rod, can realize drawing, pushing work easily, adopts electric hydraulic pump to do power source, and the operation requisite space is less, and load-bearing capacity is strong, and it is simple and reliable for structure simultaneously, and efficient is high; Adopt the middle brace rod of some according to the position of platform, realize the adjustment of six degree of freedom platform large-scale stepless; Adopt the platform web joint, two actuator base platforms of each six degree of freedom platform one side are connected and fixed through bolt reliably, thereby guarantee whole the moving of a side two vertical actuator, its relative position is constant, and is easy to adjust.
