Abstract
The invention relates to the machining of a coupling, in particular to a process for machining reamed holes on a flange type coupling. The process includes the following steps of: 1, selecting flange type half couplings which need to be processed with a pair of reamed holes; 2, sleeving the two half couplings into a core shaft; 3, fixing the two half couplings on the core shaft through bonds to form a whole body; 4, fixing the whole body on a drill press and drilling reamed holes on the whole body through the drill press; and 5, taking off the two drilled half couplings to polish the burrs. The process disclosed by invention for processing reamed holes on the flange type coupling saves time and labor, and the reamed holes on the two half couplings can reach quite high matching degree.
Description
Technical field
The present invention relates to a kind of processing technology of shaft coupling, be specifically related to a kind of processing technology of flanged joint articulation hole.
Background technology
Flanged joint has simple structure, and cost is low, can transmit larger torque, without buffering, does not allow diaxon that relative displacement is arranged, so it is low generally to be used in rotating speed, without impacting, the rigidity of axle is large, and centering preferably applications is wider; Now want two and half shaft couplings of flange connector formula shaft coupling, the general employing at two and half shaft coupling flanges bored corresponding articulation hole, be connected by screw again, the processing method of tradition articulation hole is: marked first the position of articulation hole on flange, then process respectively the articulation hole on two and half shaft couplings, the method deficiency of the articulation hole on the existing processing flange is: process respectively the articulation hole on the flange, be easy to like this occur the not corresponding of two and half shaft coupling articulation holes, although can do further contraposition revises, it is too large but deviation to occur, just can't repair, will cause scrapping of shaft coupling.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple to operate, the processing technology of the flanged joint articulation hole that yield rate is high.
In order to solve the problems of the technologies described above, the invention provides a kind of articulation hole processing technology of flanged joint, include following steps:
1) chooses flanged type half shaft coupling that needs to process articulation hole on two flanges;
2) two and half shaft couplings are inserted on the mandrel;
3) utilize key that two and half shaft couplings are fixed on and form an integral body on the mandrel;
4) this integral body is fixed on the drilling machine, utilizes drilling machine to carry out the brill of joining of articulation hole;
5) take off to join in the step 4) and bore half good shaft coupling and carry out the polishing of burr.
Flanged type half shaft coupling that needs the processing articulation hole at flanged type half shaft coupling described in the step 1.
Be a circular shaft with keyway at the mandrel described in step 2 and the step 3, when fixing half shaft coupling, need well corresponding keyway is fixed two and half shaft couplings and mandrel by flat key again; Its axle one end has boss, and the purpose of its boss is to join brill and can carry out smoothly in order to form a reaction force in joining the process of brill, to make, and considers that shaft coupling needs to bear powerful torsional forces in actual use, and the shaft coupling chosen material is forged steel.
Adopt the technical program following features: 1, owing to adopting the mode of joining brill, two and half shaft couplings can reach quite high fitness; 2, owing to using flat key to fix two and half shaft couplings and mandrel, can solve two and half shaft couplings and join the dislocation that causes when boring; 3, because an end of mandrel has boss, its effect is to join to prop up reaction force of shaft coupling generation when boring, and can carry out smoothly so that join when boring.

The specific embodiment
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As depicted in figs. 1 and 2, a kind of flanged joint articulation hole 11 processing technologys include following steps:
1) chooses on two flanges 17 also flanged type half shaft coupling 1 of undressed articulation hole 11;
2) two and half shaft couplings 1 are inserted on the mandrel 2;
3) utilize key to fix two and half shaft couplings 1 and mandrel 2, form an integral body;
4) this integral body is fixed on the drilling machine, utilizes drilling machine to carry out the brill of joining of articulation hole 11;
5) take off half shaft coupling 1 that it is good that two have been joined brill and carry out the polishing of burr.
As shown in Figure 2, be flanged type half shaft coupling 1 that has processed axis hole 12 and axis hole keyway 13 at step 1) flange formula half shaft coupling, its half shaft coupling also needs to process articulation hole.
As shown in Figure 4, in step 2) and step 3) in mandrel 2 be a circular shaft with keyway 4, when fixing half shaft coupling 1, need well corresponding half shaft coupling groove 13 is fixed two and half shaft couplings 1 and mandrel 2 by flat key 3 again; Its axle one end has boss 25, and the purpose of its boss 25 is to join brill and can carry out smoothly in order to form a reaction force in joining the process of brill, to make, and considers that shaft coupling needs to bear powerful torsional forces in actual use, and the shaft coupling chosen material is forged steel; Because adopt the mode of joining brill, two and half shaft couplings can reach quite high fitness; Use flat key 3 to fix two and half shaft couplings 1 and mandrel 2, can solve two and half shaft couplings and join the dislocation that causes when boring; One end of mandrel has boss 25, and its effect is to join to prop up reaction force of half shaft coupling, 1 generation when boring, and can carry out smoothly so that join when boring.
Above-described only is preferred embodiment of the present invention; should be understood that; for a person skilled in the art; join under the prerequisite of the method for drilling that drills and reams not breaking away from the present invention; can also make and somely not need to carry out creative work with regard to achievable improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
