[0002] Drilling machine fixtures refer to devices used to fix the object to be processed during the drilling process so that it occupies the correct position to be processed or tested. They are easy to use and widely used, and have irreplaceable use value in the field of drilling machine processing. In addition to the parts that do not require high drilling accuracy, ordinary general fixtures can be used for clamping and fixing. Special parts with high processing accuracy require special fixtures to improve the clamping and stabilization effect. Connecting rods are key components in engines, and drilling is a very important step in the processing of connecting rods. Because of the special structure of connecting rods, ordinary fixtures are not applicable.
