Abstract
The invention discloses a spherical connector comprising a crown and hydraulic pad piston rods. The crown is connected with upper spheres; each lower ball seat is connected with one hydraulic pad piston rod; each upper sphere corresponds to each lower ball seat in position; each upper sphere is a convex sphere; each lower ball seat is a concave sphere. The spherical connector is resistant to eccentric load; the problem that wear is worsened due to a crown guide auxiliary rail fully bearing eccentric load force is avoided; debugging is easier and shorter in time; after the crown is leveled, the shaft ends of piston rods of the hydraulic pads fully fit the crown, and connecting bolts are avoided bearing load.
Description
Technical field
The present invention relates to the jockey between a kind of forcing press apical cap and hydraulic die cushion parts, particularly relate to a kind of spherical connecting device.
Background technology
Tradition connects employing bolt and is fixedly connected with, and parts Contact face is plane, can only transmit axial force, to the non-axial force produced, can only be overcome by bolt or apical cap guiding rail, in the course of time, bolt deformation cannot be dismantled and even be ruptured, or apical cap guiding rail serious wear, and precision reduces.Be debug difficulties on the other hand, because apical cap is the rigid body of a body structure, be difficult to by apical cap leveling, ensure that again each hydraulic die cushion tailpiece of the piston rod supporting apical cap is all fitted completely with apical cap.
Summary of the invention
The object of this invention is to provide a kind of spherical connecting device, there is the ability of anti-bias load, the apical cap auxiliary guide rail that leads is avoided to bear offset loading force and unstable wear completely, reduce debugging difficulty, shorten debug time, after making apical cap leveling, each point hydraulic die cushion piston rod axle head is all fitted completely with apical cap, avoids connecting bolt to bear load.
For achieving the above object, the technical solution used in the present invention is:
A kind of spherical connecting device, comprise apical cap and hydraulic die cushion piston rod, it is characterized in that: apical cap is connected with upper sphere, lower ball base connecting fluid pressure pad piston rod, upper sphere is corresponding with lower ball base position, and upper sphere is convex spherical, and lower ball base is concave spherical surface.
According to described spherical connecting device, it is characterized in that: described upper sphere and lower ball base are through facing-up, and the contact area of two spheres is not less than 60%.
According to described spherical connecting device, it is characterized in that: described upper sphere is connected with apical cap by upper sphere hold-down ring; Described lower ball base is connected by screw on the axle head of hydraulic die cushion piston rod, is connected on apical cap with bolt by lower ball base hold-down ring and upper sphere hold-down ring, and the connecting hole gap of this bolt is comparatively large, can not make to become rigid body completely between sphere and lower ball base.
According to described spherical connecting device, it is characterized in that: be provided with spherical pad between described upper sphere and apical cap, upper spherical pad needs grinding, ensures that on it, end face is than end face height 0.2mm on upper sphere hold-down ring,
According to described spherical connecting device, it is characterized in that: between described upper sphere and lower ball base, be coated with lithium saponify.
Advantageous effect of the present invention is: the ability with anti-bias load, avoids apical cap guiding auxiliary guide rail to bear offset loading force completely, unstable wear.Reduce debugging difficulty, shorten debug time, after making apical cap leveling, each point hydraulic die cushion piston rod axle head is all fitted completely with apical cap, avoids connecting bolt to bear load.
