Piston pin dimension detection device

Abstract

The invention provides a piston pin dimension detection device. The piston pin dimension detection device is characterized in that four linear guide rails are arranged at two sides of a dimension bottom board, an outer circle measurement mechanism is arranged in the middle of the dimension bottom board, four length measurement pneumatic sliding stands are arranged on the linear guide rails, the outer circle measurement mechanism is driven through a sideslip cylinder, the sideslip cylinder is mounted on the dimension bottom board through a fixing board, opposite angles of the dimension bottom board are respectively equipped with a workpiece discrimination structure, the workpiece discrimination structures are fixed on the dimension bottom board through workpiece discrimination structure screws, a length measurement pneumatic sliding stand is equipped with a straight handle sensor through a sensor fixing seat, two inner sides of the length measurement pneumatic sliding stand are respectively distributed with an inner hole diameter measurement go gauge, limit boards are arranged at two sides of the dimension bottom board, a wiring duct is mounted on the dimension bottom board, and wiring of various types of cables is convenient. The piston pin dimension detection device is advantaged in that multiple geometric dimensions of five piston pins can be simultaneously detected, detection precision and efficiency are high, the detection data can be fed back in real time, and online detection of the piston pins can be realized.

Description

technical field [0001] The invention is suitable for on-line detection of geometric dimensions of a piston pin of an automobile engine, belongs to the technical field of automatic detection, and is specifically a piston pin size detection device. Background technique [0002] At present, the manufacture of piston pins has achieved automatic production, but the automation level of the matching piston pin detection is relatively low. The inspection process of most domestic manufacturers is still stuck in the manual sampling inspection method. In some factories with high production equipment, advanced measuring instruments, especially high-end product equipment, are almost all imported. Manual sampling inspection cannot guarantee the accurate measurement of core parameters and the processing quality of parts. At the same time, it will cause manual inspection errors, which cannot meet the high-quality and large-scale requirements. Off-line off-site detection, although the detec...

Manual sampling inspection cannot guarantee the accurate measurement of core parameters and the processing quality of parts. At the same time, it will cause manual inspection errors, which cannot meet the high-quality and large-scale requirements

Off-line off-site detection, although the detection accuracy is high, greatly increases the auxiliary time of conveying and clamping, and cannot realize online feedback and control of processing quality
