Abstract

An assembling bolt machine for fracture splitting(FS) connecting rods was developed

for the traditional fixing procedure for bolts could not be suitable for the FS of connecting rods. The basic structure of the assembling bolt machine and bolt assembling process were briefly introduced. Then

a virtual prototyping model for the machine was constructed based on the computer virtual technology to dynamically simulate assembling bolt processes. Torque and angle experiments were also carried out

the parameter 20Nm+95 was chosen as the assembling techniques for the FS connecting rod of a particular car. Obtained results show that the assembling techniques can satisfy its assembling requirement. Finally

the quality defects during the fixing bolts were discussed

and the solvents towards these defects were given. Dynamic simulation results indicate that the blots can be accurately transferred into bolt holes and assmbled on connecting rods. Torque and angle experiments show that the distortion of bolts during the assembling process can judge whether the axis force of bolts can satisfy the requirements and can determine the assembling techniques of control torque for connecting rods. This paper provides a reliable basis for the design of the assembling bolt machines and the research of the FS connecting rod techniques.
