Assistive tool for detecting and grouping cylinder case surfaces of motorcycle crankcases

Abstract

The invention relates to an assistive tool for detecting and grouping cylinder case surfaces of motorcycle crankcases. The assistive tool is characterized by comprising a bottom plate fixedly arranged on a working table; a plurality of locating and supporting blocks, upper surfaces of which are in the same plane, are arranged at the upper end of the bottom plate; the locating and supporting blocks are distributed along the folding surface outline of the case bodies of the motorcycle crankcases and used for supporting the case bodies of the motorcycle crankcases; upward locating pin holes are also arranged at the upper end of the bottom plate; the locating pin holes correspond with assembly holes of the case bodies of the motorcycle crankcases and used for being inserted in locating pins, so that the case bodies of the motorcycle crankcases are located above the locating and supporting blocks; a slide rail is also arranged on the bottom plate; a matched slide block is glidingly arranged on the slide rail; and a dialgauge for detecting height is installed on the slide block. According to the grouping assistive tool disclosed by the invention, both the detection cost and the detection time of the cylinder case surfaces are greatly reduced; therefore, after folding the case bodies, the flatness requirements of the cylinder case surfaces can be well ensured.

Description

technical field [0001] The invention relates to an auxiliary device for height grouping of the cylinder case surface of the crankcase body of a motorcycle. [0002] Background technique [0003] The crankcase of a motorcycle engine is generally formed by joining the left and right boxes. Due to the increasing precision requirements for the machining of the crankcase of a modern motorcycle engine. After the processing of the cylinder box surface of the left and right boxes is completed, the precision requirement of the flatness of the cylinder box surface after the box has become an important link in the manufacture of the box body. The quality of the cylinder box surface flatness directly affects the assembly quality and emission performance of the engine . Therefore, in addition to taking measures to improve the machining accuracy of the tank surface, an auxiliary device is needed to detect the flatness of the tank surface after the box is combined for grouping.

AI Technical Summary

Problems solved by technology

Among them, the height and angle of the cylinder box surface are detected by a three-coordinate detector, and the detection accuracy is relatively accurate, but the time-consuming and detection costs are too high to meet the needs of mass production

However, the traditional method of judging the flatness of the combined boxes by combining the left and right boxes not only requires a lot of manpower, but also must be delivered in two matching boxes during logistics transportation, which causes inconvenience in logistics transportation.
