Description

Technical Field

[0001] The utility model relates to the technical field of automobile connecting rod processing, in particular to a connecting rod blank large and small hole drilling and boring device. Background Art

[0002] The connecting rod group consists of a connecting rod body, a connecting rod big head cover, a connecting rod small head bushing, a connecting rod big head bearing, and a connecting rod bolt (or screw). The connecting rod group is subjected to the gas force transmitted from the piston pin, its own swing, and the reciprocating inertia force of the piston group. The magnitude and direction of these forces are cyclically 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 rigidity. When the connecting rod is produced, it needs to be processed with a drilling and boring machine.

[0003] However, the traditional drilling and boring machine tools still have the following shortcomings when in use: during the processing, after the connecting rod blank is processed, it is necessary to operate the fixture to remove the processed connecting rod blank, and then replace it with the connecting rod blank to be processed and operate the fixture to clamp and fix it. During this process, it takes a certain amount of time to disassemble and assemble the connecting rod back and forth. In order to improve production efficiency, some staff often speed up the disassembly and assembly speed, which not only causes high labor intensity in processing, but also often easily produces operational errors, resulting in deviations in the drilling accuracy of the connecting rod and an increase in the defective rate. In this regard, we proposed a connecting rod blank large and small hole drilling and boring device to solve the above problems. Utility Model Content
