Abstract
The utility model provides a metal pipe connecting device. The metal pipe connecting device comprises a pipe connecting piece. Metal pipes serving as connected objects are inserted into the two ends of the pipe connecting piece respectively. The positions, corresponding to both the metal pipes, of the pipe connecting piece are respectively provided with at least one bolt hole. A plurality of bolts are screwed into the pipe connecting piece through the bolt holes and abut against the metal pipes. The bolts are used for fixing the metal pipes through pressure generated through abutting connection. An elastic material used for extruding the metal pipes is laid in the pipe connecting piece. The bolts are screwed into the pipe connecting piece, the elastic material is laid in the pipe connecting piece, the positions of the metal pipes can be adjusted while the connected metal pipes are fastened, and therefore the metal pipes can be connected in a butt joint mode in a high-precision mode according to the fixed position relation.
Description
Technical field
The utility model relates to a kind of connection set, particularly a kind of connection set of metal tube.
Background technique
Conventionally adopt and have the modes such as clamp jaws structure, screw connection structure and welding for the link that docks metal tube at present.Wherein, the metal tube of welding easily ruptures or distortion under the state in load-bearing afterwards in connection; The general fixture mating with metal tube profile that uses of clamp jaws clamps metal tube, but, such processing requires very high to clamp precision, after clamping, the position of metal tube may slide out existing variation, make two steel pipes cannot keep set position relationship, for example straight line or certain degree; And the processing request of screw connection structure double thread is very high, cause manufacturing cost to rise.
Model utility content
The technical problems to be solved in the utility model is the defect of the not high or high cost of the relative positional accuracy in order to overcome linkage structure connection metal pipe in prior art, and the connection set of the lower and metal tube that precision is higher of a kind of cost is provided.
The utility model is to solve above-mentioned technical problem by following technical proposals: a kind of connection set of metal tube, its feature is, it includes: a cast link, described cast link is for inserting respectively one from two ends as being connected the metal tube of thing, and described cast link all offers at least one screw on the position of metal tube corresponding described in each;
Several bolts screw in described cast link by described screw, and metal tube described in butt, and described bolt is for metal tube described in the pressure fixing producing by butt;
In described cast link, be equipped with the elastic material for pushing described metal tube.
That is to say, insert respectively metal tube from the port of cast link, under the reaction force acting in conjunction that the pressure that metal tube is produced by bolt in cast link inside and elastic material produce, be held.So, the relative position of metal tube and cast link can stretch into and stretches out cast link and adjust with the position that changes bolt and metal tube and connect by screwing bolt.
Preferably, described bolt is moment bolt.
Use moment bolt to adjust the relative position of metal tube with degree of precision herein.
Preferably, described elastic material is arranged in the direction of described pressure in described cast link, produce and the reaction force of described pressure in contrast for pushing described metal tube, and with described bolt together fastening described metal tube in described cast link.
Preferably, described cast link is a cast fixture, and described cast fixture includes one first fastening piece and one second fastening piece, and described the first fastening piece and described the second fastening piece are spliced to form the fastening structure of a cast for fastening described metal tube.
Herein, the connection metal pipe clamping by cast fixture, can load and unload metal tube more easily, and, the required precision of the link position of the connection set of the metal tube relating to due to the utility model to metal tube is very high, often need to the each parts in inside be proofreaied and correct, be safeguarded, be easier to safeguard and be arranged to cast fixture.
Preferably, the side of described the first fastening piece and described the second fastening piece is provided with at least one wing joint;
On described wing joint, be provided with screw;
Described the first fastening piece and described the second fastening piece are by described wing joint bolt.
Preferably, the inner side of described the first fastening piece and described the second fastening piece is all equipped with described elastic material;
On described the first fastening piece and described the second fastening piece, be provided with several for being screwed into the screw of moment bolt.
Positive progressive effect of the present utility model is: be screwed in cast link by bolt, and lay elastic material in cast link, can in the fastening metal tube being connected, adjust the position of metal tube, metal tube can high-precisionly be docked according to set position relationship.
