Description

A kind of joint ring combination

Technical field

The utility model relates to a kind of joint ring, especially a kind of joint ring combination of high working property energy.

Background technique

Inside miscellaneous automobile component, there is a kind of soldering part for being joint ring, the part is conventional by a circle Ring and one is formed with bar using electric resistance welding.Due to needing to fill the drag-line of a steel inside round tube, so the pipe shaft of bar must It must be hollow.And hollow there must be certain length.Since the connection of annulus and bar needs certain weld strength, if bar is adopted Electric resistance welding is carried out with hollow pipe, intensity is hardly consistent with requirement.In order to guarantee enough weld strengths, in joint ring In the case that the length requirement of the bar of part is shorter, bar generally uses solid tubes to manufacture as blank, and solid tubes are first cut into rule Then solid tubes are bored sky with drilling machine again by fixed length from one end to the other end.When electric resistance welding the solid-end of round tube with Annulus welding, the joint ring weld strength welded in this way can satisfy requirement.But the if length of the bar of joint ring Degree requirement is longer, and solid tubes are drilled to hollow method using drilling machine and are difficult to realize, at this moment bar can only just take hollow pipe, be Guarantee bar and annulus have enough welding surfaces when welding, and improve the weld strength of joint ring, need to be in hollow pipe when welding A solid plug is knocked in one end.The material of plug is consistent with round tube, and outer diameter and round tube inside diameter size are using interference fit Size, to guarantee that plug can combine closely with round tube.But the welding of the bar and annulus carried out by the way of son of jumping a queue, Integral strength is not still high, and stability is also poor, and the qualification rate of product is very low.Destructiveness is detected as plus joint ring weld strength again When detection, joint ring is fixed on tension tester for detection, and puller system applies the power of opposite direction to ring and bar, until will Until ring and bar pull.So product (regardless of qualified or not) after testing can all be scrapped, in order to guarantee product quality and There is operability.The method that such part often uses sampling Detection randomly selects certain amount progress in a collection of product Detection, the product qualification inspected by random samples are then considered as entire block qualification.Part regards by the gross if part one inspected by random samples is unqualified It is unqualified.So using this method for sub- welded hollow pipe of jumping a queue, the risk and cost is all very high.It is badly in need of a kind of processability Reliable joint ring is connected between the good ring bar of energy and between drag-line.

Summary of the invention

The utility model is to overcome existing hollow pipe low with annulus welding strength of electric resistance welding, the disadvantage of stability difference, this reality A kind of new joint ring combination is provided with novel, makes it possible to effectively improve the machinability of joint ring.

In order to solve the above technical problems, the technical solution of the utility model is as follows:

There is provided a kind of joint ring combination comprising joint ring, connector rod, gripping sleeve, gap, external screw thread, clamping element, interior spiral shell Line, joint ring and connector rod are integrally formed by injection molding or casting technique, reduce technology difficulty, and for opposite fusion joining process, Intensity is detached to be easier to ensure that；

In the gripping sleeve of sheet or strip that connector boom end is certain length, a part of the gripping sleeve as connector rod It is integrally formed simultaneously, there are gap, gripping sleeves to be divided into multi-disc by gap for gripping sleeve, can be arranged symmetrically for even slice, multiple Gripping sleeve constitutes annulus；

Gap length is 10mm to 15mm, and width is 1mm to 1.5mm；

External screw thread is equipped with outside gripping sleeve, externally threaded length is consistent with gap length or is longer than gap length 1mm extremely 2mm。

Joint ring combination further includes a clamping element, which is a hexagonal columnar member, and clamping element internal diameter is equal to Gripping sleeve outer diameter, clamping element inner hole are additionally provided with an internal screw thread, the external thread part of the gripping sleeve of clamping element internal screw thread and connector rod Split-phase adaptation.

In use, first by clamping element pass through connector rod on gripping sleeve male thread portion, after by drag-line merging clamp 3 in Kong Zhong, then clamping element is retracted to the male thread portion of gripping sleeve, and screw the two, so that the fixation to drag-line is completed, behaviour Make convenient and efficient.

Compared with prior art, the beneficial effect of technical solutions of the utility model is:

Endless tube is arranged by docking headring and connector rod to be integrally formed, so that strength of joint is reliable, ratio of briquetting is high, avoids Unstable process is welded, to reduce connection risk, improves production efficiency；Cooperated by setting clamping element and connector rod so that connecing The connection reliability of headring and drag-line can be promoted.
