Problems solved by technology

Although this device can conveniently detect the position of each machining hole on the flywheel housing, since the measurement pin is inserted into the machining hole of the flywheel housing and the pin hole of the gauge plate for comparison to judge, there is a subjective judgment error of the operator when judging, and with the As the number of times the gauge plate is used increases, the pin holes on the gauge plate and the pins are worn out, and the detection error is also increasing; in addition, the device can only detect the position of the machining hole on the flywheel shell, and cannot simultaneously detect the position of each hole on the flywheel shell. The flatness and symmetry of the processed surface are tested, which is not very practical

Abstract

The invention relates to a measuring apparatus applicable to multiple-flywheel shell surface measurement and a measuring method. The measuring apparatus includes a measuring tool base, a rotating shaft, a moving plate, a fixed plate, a measuring tool, a gauge-setting block and a measurement block; positioning holes matched with a flywheel shell are formed in the measuring tool base, and positioning pins are respectively arranged in the positioning holes; a plurality of measuring holes are formed in the measuring tool base, and positioning drill sleeves are respectively arranged inside the measuring holes; the rotating shaft is perpendicular to the moving plate, and the upper end of the rotating shaft is rotatably inserted in one end of the moving plate, and the lower end of the rotating shaft is inserted into the positioning drill sleeve; the fixed plate is vertically fixed on the other end of the moving plate, and a measuring end of the measuring tool passes through the fixed plate, and extends to the outer side of the moving plate; and the gauge-setting block is vertically fixed on the measuring tool base, and the gauge-setting block and one of the measuring holes jointly calibrate the measuring tool. According to the measuring apparatus of the invention, with once gauge setting performed, measurement of the flatness, location degree, end surface distance and the like of the flywheel shell can be realized, and detection efficiency can be improved. With the measuring apparatus applicable to the multiple-flywheel shell surface measurement adopted, 360-degree all-dimensional measurement of a workpiece can be realized with convenient and fast operation.
