Description
Technical field
The utility model relates to the jockey between a kind of forcing press apical cap and hydraulic die cushion parts, particularly relates 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 purpose of this utility model 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 adopted in the utility model 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.
The utility model has the advantages of and be: the ability with anti-bias load, avoid 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.

In accompanying drawing: 1, apical cap; 2, upper spherical pad; 3, upper sphere hold-down ring; 4, lower peripheral surface hold-down ring; 5, pad; 6, hydraulic die cushion piston rod; 7, upper sphere; 8, lower ball base; 9, apical cap guiding rail; 10, hydraulic die cushion.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, 2, a kind of spherical connecting device, comprises apical cap 1 and hydraulic die cushion piston rod 6 to the utility model, it is characterized in that: apical cap 1 is connected with upper sphere 7, lower ball base 8 connecting fluid pressure pad piston rod 6, upper sphere 7 is corresponding with lower ball base 8 position, upper sphere 7 is convex spherical, and lower ball base 8 is concave spherical surface.According to described spherical connecting device, it is characterized in that: described upper sphere 7 and lower ball base 8 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 7 is connected with apical cap 1 by upper sphere hold-down ring 3; Described lower ball base 8 is connected by screw on the axle head of hydraulic die cushion piston rod 6, with bolt, lower ball base hold-down ring 4 and upper sphere hold-down ring 3 are connected on apical cap 1, the connecting hole gap of this bolt is comparatively large, can not make to become rigid body completely between sphere 7 and lower ball base 8.According to described spherical connecting device, it is characterized in that: between described upper sphere 7 and apical cap 1, be provided with spherical pad 2, upper spherical pad 2 needs grinding, ensure that on it, end face is than end face height 0.2mm on upper sphere hold-down ring 3, according to described spherical connecting device, it is characterized in that: between described upper sphere 7 and lower ball base 8, be coated with lithium saponify.
Concrete performance of the present utility model as shown in Figure 1, 2, upper sphere 7, lower ball base 8 need facing-up, make it contact surface and be not less than 60%, upper sphere 7 is connected with apical cap 1 by upper sphere hold-down ring 3, lower ball base 8 is connected with hydraulic die cushion piston rod 6 axle head by screw, with bolt, lower ball base hold-down ring 4 and upper sphere hold-down ring 3 are connected on apical cap 1, this connecting hole gap is larger, can not make to become rigid body completely between sphere 7 and lower ball base 8, ensure that upper and lower sphere relative position can automatic fine tuning.Upper spherical pad 2 needs grinding, ensures that on it, end face, than end face height 0.2mm on upper sphere hold-down ring 3, is coated with lithium saponify between upper sphere 7 and lower ball base 8.
