Crankshaft-connecting-rod-neck width detection device

Abstract

The invention discloses a crankshaft-connecting-rod-neck width detection device. The crankshaft-connecting-rod-neck width detection device is characterized in that an axial servo sliding table is arranged on a bottom support, a radial servo sliding table is arranged on the axial servo sliding table, a measuring head base is installed on the radial servo sliding table, a measuring assembly is installed on the measuring head base, and the position can be adjusted up and down before detection; a drag chain metal plate is arranged on one sides of the axial servo sliding table the radial servo sliding table, one end of a wiring drag chain is fixed on the drag chain metal plate, the other end of the wiring drag chain is fixed on a drag-chain fixing metal plate, and the measuring assembly comprises a U-shaped support, inductance probes and a measuring tip end; the two inductance probes are installed on the two edges of the U-shaped support respectively, the measuring tip end is arranged inside the U-shaped support, the front end of the measuring tip end is in contact with the end face of a connecting rod neck, and the back end of the measuring tip end presses the inductance probes. The crankshaft connecting rod neck width detection device has the advantages that as automatic detection is adopted, the detection speed and accuracy of a key groove are greatly increased; as the on-line detection mode is adopted, the autonomous perception function, the quality statistics function and the like are achieved, and the quality information of products is fed back in time.

Description

technical field [0001] The invention is suitable for detecting the width of a crankshaft connecting pin neck, and belongs to the technical field of crankshaft testing; in particular, it relates to a crankshaft connecting pin neck width detecting device. Background technique [0002] The structure of the engine crankshaft is complex, and the processing quality of the crankshaft is directly related to the reliability, service life, vibration and noise of the automobile engine. In the manufacturing process, it is necessary to accurately measure and control multiple dimensions and geometric tolerances, including length, angle, shape and position, etc., such as the diameter of the main shaft and connecting rod shaft, the width of the journal, roundness, cylindricity, space phase angle , Coaxiality between the main shafts, etc. At present, manual sampling or visual image are mostly used to detect the width of parts. Manual detection has low efficiency and high subjectivity. Image...
