Technical Field

[0001] The invention relates to the field of clamping mechanism equipment, and in particular to a connecting rod fixing device. Background Art

[0002] As the main transmission component of the engine, the connecting rod is usually affected by mechanical force and thermal deformation during its processing. In order to prevent the possible position displacement or movement, which may lead to a decrease in processing accuracy or even a processing accident, a positioning tool is needed to fix and position it; However, in the existing positioning tooling for fixing the big head or the small head of the connecting rod, in order to prevent the connecting rod from shaking and deviating during processing or re-clamping, the positioning size and fixing position are mostly fixed and not convenient to adjust. When processing different parts of one or different connecting rods, positioning fixtures with different positioning sizes are usually required to fix the connecting rod, so that the connecting rod processing process requires multiple fixing devices, which increases the production cost and the time consumed in the process of switching fixtures.

[0003] Therefore, a new connecting rod fixing device is needed to solve the problem that the existing fixing device will deviate when fixing connecting rods of different specifications. Summary of the invention
