Abstract
The utility model relates to an automobile engine connecting rod forges fixes a position frock with processing of forging hammer jetting mouth should fix a position the frock and include drill bit, jetting mouth, fix a position frock main part, stopper and clearance adjustment shell fragment, location frock main part on processing have a work piece locating hole, the stopper setting is work piece locating hole one side in the frock main part of location, the clearance adjustment shell fragment sets up on the stopper, the drill bit sets up directly over the jetting mouth, adds and jets the mouth setting in the work piece locating hole man -hour. The utility model has the advantages of simple and reasonable structure, jetting mouth portion drilling location is accurate, convenient to use.
Description
Technical field
The utility model relates to connection rod of automobile engine forging field, specifically a kind of connection rod of automobile engine forging forging hammer winding-up mouth locating and machining frock.
Background technology
Connection rod of automobile engine is one of major part of automobile engine, and its effect is that the power of being born by piston passes to bent axle, promotes crank rotation, becomes the rotary motion that the reciprocating motion of piston is bent axle.Connection rod of automobile engine will bear the gas pressure that piston pin transmits at work, the reciprocating inertia force of piston connecting rod unit and big end flexing rotate the effect of the rotating inertia force produced, and connecting rod itself is again a longer body of rod, therefore requires that connecting rod will have enough intensity, rigidity, weight will try one's best gently.
The similar bolt of basic configuration of winding-up mouth, bores a hole, is arranged in an interference fit in hole by the copper nozzle processed at head place.The method of tradition processing forging hammer winding-up mouth is the steel round bar selecting size suitable, and machined by operations such as car, milling, brills, this method efficiency comparison is low, waste material.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of simple and reasonable, the boring accurate positioning of winding-up mouth portion, connection rod of automobile engine forging forging hammer winding-up mouth locating and machining frock easy to use.
The purpose of this utility model is achieved in that this positioning tool comprises drill bit, winding-up mouth, positioning tool main body, limited block and gap adjustment shell fragment, described positioning tool main body is processed with Workpiece fixing hole, limited block is arranged on side, Workpiece fixing hole in positioning tool main body, described gap adjustment shell fragment is arranged on limited block, described drill bit is arranged on directly over winding-up mouth, adds mouth of jetting man-hour and is arranged in Workpiece fixing hole.
Advantage of the present utility model and good effect are:
1, the utility model overcomes the shortcoming and defect of prior art, adopts suitable bolt standard component, is fixed in locating and machining frock main body simultaneously, and directly upper drilling machine is processed, and not only increases operating efficiency, also reduces processing cost.
2, the utility model does not need to use the expensive steel round bar of price comparison, machines winding-up mouth by operations such as car, milling, brills, and only need buy bolt standard component common on market and then hole and can to realize jetting the processing of mouth, simple and reasonable.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Detailed description of the invention
Shown in accompanying drawing 1: this positioning tool comprises drill bit 1, winding-up mouth 2, positioning tool main body 3, limited block 4 and gap adjustment shell fragment 5, described positioning tool main body 3 is processed with Workpiece fixing hole 6, limited block 4 is arranged on side, Workpiece fixing hole 6 in positioning tool main body 3, described gap adjustment shell fragment 5 is arranged on limited block 4, described drill bit 1 is arranged on directly over winding-up mouth 2, adds mouth 2 of jetting man-hour and is arranged in Workpiece fixing hole 6.
During processing winding-up mouth, steel round bar can not be adopted to process, and use suitable bolt standard component; Concrete procedure of processing is: mouth 2(bolt standard component of jetting) be fixed on the Workpiece fixing hole 6 of positioning tool main body 3, drill bit 1 is aimed at Working position and is directly processed by drilling machine, decreases manufacturing procedure, saves material.
Due to winding-up mouth 2(bolt standard component) appearance and size not necessarily completely the same, so assisted each winding-up mouth 2(bolt standard component by the gap adjustment shell fragment 5 on limited block 4 and limited block 4) accurate location.
