Abstract

The invention relates to automatic assembly equipment for a fixed torque bolt of a splitting connecting rod, which is special equipment provided for the assembly process of a bolt of a splitting connecting rod, and is applicable to a straight incision connecting rod and a tilted incision connecting rod. The equipment mainly comprises a mechanical system and a pneumatic system, wherein the mechanical system comprises a connecting rod locating mechanism, a connecting rod compressing and oscillation deslagging mechanism, a connecting rod cover opening and closing mechanism, a fixed torque wrench and feeding structure, a bolt rotation and guidance mechanism, a bolt automatic feeding and separation mechanism and the like. The connecting rod mechanism comprises a connecting rod big-end locating piece and a connecting rod small-end locating piece, connecting rod big-end and small-end locating clamps are replaceable to suitable for the processing of connecting rods with different models, the connecting rod small-end locating clamp can be regulated and located within a certain range along X direction and Y direction, so as to be applied to the straight incision connecting rods and tilted incision connecting rods. The equipment of the invention is adopted to assembly the splitting connecting rod bolt, thus significantly improving the processing quality significantly, ensuring bolt assembly to meet design requirements, avoiding slag inclusion of surface of fracture, ensuring the reassembling accuracy of the splitting connecting rod and the like.

Description

Technical field: [0001] The invention relates to special equipment for assembling cracked connecting rod bolts at a fixed torque, and belongs to the technical field of engine connecting rod processing and manufacturing. Background technique: [0002] The traditional processing method of the engine connecting rod is separate processing, that is, the whole connecting rod is cut off by machining, milled, and then the joint surface is ground. At the same time, a large number of processing procedures and finishing equipment are required to process the connecting rod body and the connecting rod separately. Cover bolt holes. Its processing accuracy and assembly quality are difficult to control, the production efficiency is low, and the manufacturing cost is high. The connecting rod cracking process is the latest processing technology for connecting rods. The cracking process of the connecting rod is shown in Figure 1. That is to pre-process two cracking grooves in the big end ho...
