Abstract
The utility model discloses a tension device of a jaw crusher, which comprises a tension screw, a frame body, a front base plate, a spring, a cover plate, a concave spherical seat and a convex spherical seat; wherein the tension screw sequentially passes through the frame body, the front base plate, the spring, the cover plate, the concave spherical seat and the convex spherical seat, and a nut is arranged at the convex spherical seat part, so as to lead the spring to be clamped between the front base plate and the cover plate. In the utility model, the concave spherical seat and the convex spherical seat are arranged additionally between the cover plate and the nut, namely a spherical joint support is arranged therein. During the upward and downward swinging of the tension screw and through the upward and downward swinging of the convex spherical seat, the nut is always perpendicular to the tension screw, the cover plate is always perpendicular to the spring, the direction of the acting force is always coincided with the center of the tension screw, and the spring is not subject to the offset load force, therefore the fatigue failure of the tension screw and the spring is reduced, the operation efficiency is improved, and the using cost is lower.
Description
Technical field
The utility model relates to a kind of take-up device of jaw crusher.
Background technology
The structure of existing jaw crusher take-up device as shown in Figure 1, comprise stretching screw 1, Rack Body 2, fore beam 3, spring 4, cover plate 5 and nut 6, after described stretching screw 1 passes described Rack Body 2, fore beam 3, spring 4 and cover plate 5 successively, 5 places install nut 6 at cover plate, make described fore beam 3 and cover plate 5 clamp described spring 4.In the motion process of jaw crusher, stretching screw 1 swings up and down, apply a power that constantly moves up and down for spring 4 by nut 6 and cover plate 5, and the direction of this power does not overlap with the center of spring 4 and stretching screw, thereby aggravated the fatigue damage of stretching screw 1 and spring 4, cause stretching screw 1 and spring 4 frequently to be changed, not only influence operating efficiency, and cause use cost too high.
Summary of the invention
The purpose of this utility model is the take-up device that a kind of jaw crusher is provided at the existing deficiency of above-mentioned technology, can have longer service life, and with low cost.
For achieving the above object, the utility model can be taked following technical proposals:
The take-up device of jaw crusher described in the utility model, comprise stretching screw, Rack Body, fore beam, spring, cover plate, concave spherical surface seat and protruding spheric seating, described stretching screw passes described Rack Body, fore beam, spring, cover plate, concave spherical surface seat and protruding spheric seating successively, and nut is housed at protruding spheric seating place, make described spring be sandwiched between described fore beam and the cover plate.
The contact-making surface of described concave surface ball seat and convex surface ball seat is a sphere, is installed on the stretching screw on the position between cover plate and the nut.
The utility model promptly is equivalent to be provided with a globe joint at this and supports by increase concave spherical surface seat and protruding spheric seating between cover plate and nut.In the process that stretching screw swings up and down, by swinging up and down of protruding spheric seating, nut is all the time perpendicular to stretching screw, cover plate is all the time perpendicular to spring, make the direction of active force overlap all the time with the center of stretching screw, spring is not subjected to offset loading force, thereby has reduced the fatigue rupture of stretching screw and spring, improved operating efficiency, use cost is also cheaper.
