Abstract
The invention discloses a fixing and connecting structure of a tension and pressure spring. The fixing and connecting structure of the tension and pressure spring comprises a bolt. A bolt via hole is formed in the center of a protrusion pressing block body. One end of the protrusion pressing block is a cylinder with a small diameter and the other end of the protrusion pressing block is a stepped cylinder. The cylinder with the small diameter is matched with a tension and pressure spring hole. The inner annular surface of the stepped cylinder is placed on the inner surface of an incomplete support circle of the tension and pressure spring. The end face of the cylinder with the small diameter of the protrusion pressing block is opposite to a connection part. A notch part is arranged on the stepped cylinder of the protrusion pressing block, wherein the notch part is the same as and opposite to a spring body on the incomplete part of an incomplete tension and pressure spring. The inner surface of the notch part is the outer peripheral surface of the cylinder with the small diameter. The fixing and connecting structure of the tension and pressure spring has the advantages that the end face of the tension and pressure spring contacts with the connection part reliably and occurrence of deviation from the center of the spring is avoided.
Description
Technical field:
The present invention relates to a kind of linkage structure of spring, particularly a kind of fixed connection structure of drawing-pressing spring.
Background technique:
Drawing-pressing spring, due to not only tension but also pressurized during work, requires that spring can not have with link all the time and loosens and depart from spring center.Conventional drawing-pressing spring two end supports circle is generally not less than 1 circle, and the end face of its bracing ring is complete plane, and its inner ring is more completely circular, and the drawing-pressing spring of this form generally adopts bolt or bolt shimming to be fixed connection; But bracing ring is less than to the drawing-pressing spring of 1 circle, the end face of spring is not complete planar annular, and inside and outside circle is all imperfect, and its home position cannot be determined, thus can not adopt above-mentioned fixing mechanism.
Summary of the invention:
The object of this invention is to provide a kind of fixed connection structure, make bracing ring for the drawing-pressing spring of whole circle and connecting plate have more complete surface of contact and the fixed connection structure of a kind of drawing-pressing spring offset does not occur at its center.
The technological scheme realizing the object of the invention is, a kind of fixed connection structure of drawing-pressing spring, comprise bolt, it is characterized in that: the center of convex briquetting body is provided with bolt through-hole, one end of this convex briquetting is the minor diameter cylinder the other end is stepped cylinder, described minor diameter cylinder and drawing-pressing spring hole match, the interior annular surface of described convex rank cylinder is placed on the imperfect bracing ring internal surface of drawing-pressing spring, the minor diameter cylinder end face of above-mentioned convex briquetting is relative with link, the stepped cylinder of above-mentioned convex briquetting be provided with one piece identical with the spring body of the imperfect part of imperfect drawing-pressing spring and relatively, the internal surface of this barbed portion is the outer circumferential face of described minor diameter cylinder.
The end face that the present invention has drawing-pressing spring compared with the prior art contacts the remarkable advantage reliably and not departing from spring center with link.
Accompanying drawing illustrates:
Fig. 1 is the structural representation that drawing-pressing spring of the present invention is connected with link, and Fig. 2 is the structural representation of convex briquetting and drawing-pressing spring and link; Fig. 3 is the perspective view of convex briquetting.
Embodiment:
Complete bracing ring is not had in order to solve drawing-pressing spring termination, the center of spring is not departed from when making itself and link plane have complete bracing ring and this drawing-pressing spring and link surface can be made to have complete surface of contact and drawing-pressing spring is worked, present invention employs convex briquetting, the structure of this convex briquetting is stepped cylinder, diameter and the drawing-pressing spring hole of its one end minor diameter cylinder match, its the other end is major diameter stepped cylinder, the diameter of this stepped cylinder should be able to be pressed on spring body, make itself and link fixed, this stepped cylinder is provided with breach, breach size is identical with the partial spring body in the imperfect bracing ring of drawing-pressing spring not being plane, the supporting part of this imperfect bracing ring spring is 240 degree, also 270 degree are had, for 270 degree of bracing ring drawing-pressing springs, in the stepped cylinder of convex briquetting a 90 degree partial removal is formed 90 degree of breach, the cylinder of what breach was relative therewith is minor diameter cylinder, the height of above-mentioned stepped cylinder is the height of the lead angle of spring body 90 degree, the center of above-mentioned convex briquetting body is provided with bolt through-hole.
Of the present inventionly be connected and fixed method, first the minor diameter cylinder of convex briquetting is placed in the hole of the imperfect bracing ring of drawing-pressing spring, make annular end face in stepped cylinder be placed in this imperfect bracing ring on show, bolt is through at after in the bolt through-hole of this convex briquetting, rotating convex briquetting makes the uneven part of its breach and drawing-pressing spring relative, this tight a bolt on nut, drawing-pressing spring is made to be fixed on link, by aforesaid operations method, by another convex briquetting, the imperfect bracing ring of the drawing-pressing spring the other end and another link are fixed together therewith again, because the minor diameter cylinder of convex briquetting is identical with drawing-pressing spring hole, therefore drawing-pressing spring can not depart from center in machine work, also can not loosen with link.
Claims (1)
1. the fixed connection structure of a drawing-pressing spring, comprise bolt, it is characterized in that: the center of convex briquetting body is provided with bolt through-hole, one end of this convex briquetting is the minor diameter cylinder the other end is stepped cylinder, described minor diameter cylinder matches with drawing-pressing spring hole and identical, the interior annular surface of described stepped cylinder is placed on the imperfect bracing ring internal surface of drawing-pressing spring, the minor diameter cylinder end face of above-mentioned convex briquetting is relative with link, this stepped cylinder is provided with breach, breach size is identical with the partial spring body in the imperfect bracing ring of drawing-pressing spring not being plane, 90 degree of partial removal in the stepped cylinder of described convex briquetting form 90 degree of breach, the internal surface of barbed portion is the outer circumferential face of described minor diameter cylinder, the height of stepped cylinder is the height of the lead angle of spring body 90 degree.
