Description
Technical field
The chain structure that the utility model relates to a kind of manufacture method of chain and adopts this manufacture method to produce.
Background technology
The chain that all works is carried is usually all with the annex of convey materials.The form of this annex can be made of one with carrier bar, also can separate with carrier bar, and adopt method and the carrier bar of welding or riveted joint to be connected to one.The employing welding process has the following disadvantages: connect precision not high, annex and carrier bar easily produce dislocation; Welding easily produces tiny crack, easily fracture in use, and the life-span is low; The employing riveting has the following disadvantages: time-consuming, and operating difficulties; Must adopt at least two rivets that annex and carrier bar are located; Be only suitable for being connected of tabular annex and carrier bar.
Summary of the invention
The purpose of this utility model is to provide that a kind of annex and carrier bar are connected firmly, the connection structure of failure-free carrier bar and annex.
In order to achieve the above object, the technical solution of the utility model is: the connection structure of a kind of carrier bar and annex, comprise carrier bar and annex, all there is a pin-and-hole at the two ends of carrier bar, one side of described annex has wedge, a through hole is arranged on described carrier bar, the shape of this through hole and the shape of wedge match, described wedge inserts in through hole, and with the through hole flush fit, the seam with the side of wedge and carrier bar corresponding side of described annex relies on and is welded and fixed, and through hole other end place's dependence of the head of described wedge and carrier bar is welded and fixed.
The wedge of described annex is the pillar of semi-circular cross-section, and the through hole of described carrier bar is the semi-circular hole that the pillar with semi-circular cross-section matches.
The wedge of described annex is the pillar of square-section, and the through hole of described carrier bar is the rectangular opening that the pillar with the square-section matches.
Described annex is the piece body, has connecting bore on the piece body.
The central axis of described connecting bore and the central axis of pin-and-hole are perpendicular, and perpendicular with the length direction of carrier bar.
The plane parallel of the axial plane of the pillar of the semi-circular cross-section of described wedge and the central axis of crossing two pin-and-holes, and it is crossing with the cylinder of the pillar of semi-circular cross-section to cross the plane of central axis of two pin-and-holes.
The plane parallel of the axial plane on the long limit of the pillar of the square-section of described wedge and the central axis of crossing two pin-and-holes, and it is crossing with the cylinder of the pillar of square-section to cross the plane of central axis of two pin-and-holes.
Due to the effect of wedge, even weld cracking, annex does not come off yet, and puts off until some time later the existence due to wedge, and the impact of external force and vibration butt welded seam is little; Be welded and fixed because the seam of described annex and carrier bar one side relies on, other end place's dependence of the head of described wedge and carrier bar through hole is welded and fixed, and this two-sided welding guarantees not occur the phenomenon that annex separates with carrier bar.The through hole of wedge and carrier bar coordinates and adds two-sided being welded and fixed and can make that to be connected precision high, and annex and carrier bar can not produce dislocation.
On the pillar of semi-circular cross-section or the pillar of square-section and carrier bar, the through hole of respective shapes coordinates, and can either protect intensity and can protect precision again.
In a word, the connection structure of carrier bar of the present utility model and annex has strengthened the joint fastness, reliable of annex and carrier bar, easy fracture not in use, and the life-span is long.
