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 the fixed connection structure of a kind of linkage structure of spring, particularly a kind of drawing-pressing spring.
Background technique:
Drawing-pressing spring requires spring can not have loosening with link all the time and depart from spring center due to when work not only tension but also pressurized.Conventional drawing-pressing spring two end supports circle generally is 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 for the drawing-pressing spring of bracing ring less than 1 circle, the end face of spring is not complete planar annular, and inside and outside circle is all imperfect, and its home position can't be determined, thereby can not adopt above-mentioned fixing mechanism.
Summary of the invention:
The purpose of this invention is to provide a kind of fixed connection structure, make bracing ring that the fixed connection structure of a kind of drawing-pressing spring that more complete surface of contact and its center be not offset not arranged for the drawing-pressing spring of whole circle and connecting plate.
the technological scheme that realizes 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 protruding briquetting body is provided with bolt through-hole, one end of this protruding briquetting is that 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 protruding rank cylinder is placed on the imperfect bracing ring internal surface of drawing-pressing spring, the minor diameter cylinder end face of above-mentioned protruding briquetting is relative with link, it is identical and relative that the stepped cylinder of above-mentioned protruding briquetting is provided with the spring body with the imperfect part of imperfect drawing-pressing spring, 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 that reliably and does not depart from spring center with link.
Description of drawings:
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 protruding briquetting and drawing-pressing spring and link; Fig. 3 is the perspective view of protruding briquetting.
Embodiment:
there is no complete bracing ring in order to solve the drawing-pressing spring termination, the center that makes itself and link plane that complete bracing ring be arranged and do not depart from spring can make this drawing-pressing spring and link surface complete surface of contact be arranged and make drawing-pressing spring work the time, the present invention has adopted protruding briquetting, the structure of this protruding briquetting is stepped cylinder, the diameter of one end minor diameter cylinder and drawing-pressing spring hole match, its the other end is the 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, the partial spring body that in breach size and the imperfect bracing ring of drawing-pressing spring is not the plane is identical, the supporting part of this imperfect bracing ring spring is 240 degree, also have 270 the degree, take 270 degree bracing ring drawing-pressing springs as example, in the stepped cylinder of protruding briquetting 90 degree part is removed formed one 90 degree breach, what breach was relative therewith is the cylinder of 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 protruding briquetting body is provided with bolt through-hole.
the method that is connected and fixed of the present invention, first the minor diameter cylinder of protruding 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, after bolt is through in the bolt through-hole of this protruding briquetting, rotating protruding briquetting makes the uneven part of its breach and drawing-pressing spring relative, nut on this tights a bolt, drawing-pressing spring is fixed on link, imperfect bracing ring and another link of the drawing-pressing spring the other end are fixed together therewith with another protruding briquetting by the aforesaid operations method again, because the minor diameter cylinder of protruding briquetting is identical with the drawing-pressing spring hole, therefore drawing-pressing spring can not depart from the center in machine work, can be not loosening with link yet.
Claims (1)
1. the fixed connection structure of a drawing-pressing spring, comprise bolt, it is characterized in that: the center of protruding briquetting body is provided with bolt through-hole, one end of this protruding briquetting is that 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 protruding rank cylinder is placed on the imperfect bracing ring internal surface of drawing-pressing spring, the minor diameter cylinder end face of above-mentioned protruding briquetting is relative with link, it is identical and relative that the stepped cylinder of above-mentioned protruding briquetting is provided with the spring body with the imperfect part of imperfect drawing-pressing spring, the internal surface of this barbed portion is the outer circumferential face of described minor diameter cylinder.
