Description

Technical Field

[0001] The invention belongs to the technical field of connecting rod processing, and particularly relates to a deep hole processing device for large connecting rods. Background Art

[0002] The connecting rod group consists of a connecting rod body, a connecting rod big end cap, a connecting rod small end bushing, a connecting rod big end bearing shell and connecting rod bolts (or screws), etc. The connecting rod group bears the gas force transmitted by the piston pin, its own swing and the reciprocating inertia force of the piston group. The magnitudes and directions of these forces are periodically changing. Therefore, the connecting rod is subjected to alternating loads such as compression and tension. The connecting rod must have sufficient fatigue strength and structural stiffness. Insufficient fatigue strength often causes the fracture of the connecting rod body or connecting rod bolts, and then leads to major accidents of the whole machine being damaged. If the stiffness is insufficient, it will cause the bending deformation of the rod body and the out-of-round deformation of the connecting rod big end, resulting in eccentric wear of the piston, cylinder, bearing and crankpin, etc.;

[0003] As described in the patent application with the reference publication number CN112620700A for an automobile connecting rod hole processing device, it includes a bottom plate and a boring machine and a connecting rod positioning and supporting structure provided on the bottom plate. The connecting rod positioning and supporting structure includes a rotating disk and a motor for driving the rotating disk. The rotating disk is provided with a connecting rod positioning structure for positioning the connecting rod. The motor is provided with a driving gear. The rotating disk is of a disk structure. The center of the rotating disk is provided on the bottom plate through a rotating shaft. A gear ring meshing with the driving gear is provided on the outer edge of the rotating disk. The structure of this automobile connecting rod hole processing device is reasonably designed. The placement and positioning of the connecting rod and the removal after processing are completed do not require stopping the machine. Only by rotating the connecting rod 180 degrees away from the tool can it be done, and the operation is safe and efficient;

[0004] In the deep hole processing of connecting rods, during the deep hole processing of different models of connecting rods and at different positions on the connecting rod, the hole position needs to be positioned. General deep hole equipment does not have a calibration mechanism (such as the above technical means) to accurately bore the deep hole. Before boring the deep hole of the existing connecting rod, usually a small hole is first drilled on the workpiece for positioning and processing. The operation takes a long time, the efficiency is low, and there is still a probability of deviation. In order to avoid the above situation, a deep hole processing device for large connecting rods is provided now. Summary of the Invention
