Flywheel cover basin mouth and end face run-out detection device

Abstract

The invention discloses a flywheel cover basin mouth and end face run-out detection device. A bottom plate is provided with a plurality of base plates for supporting workpieces. Some base plates are provided with positioning pin stepped holes which are used for the passing of positioning pins, wherein the positioning pins are used for connecting a bottom plate and pin shaft holes on a detected flywheel cover. A fixed central spindle is vertically disposed on the bottom plate. A rotating body which is used for driving a dial indicator to rotate is disposed at the upper end of the fixed central spindle through a bearing. The dial indicator is connected with the rotating body through a magnetic force meter seat. The fixed central spindle comprises a main body, a lower shaft which is located at the lower end of the main body and is connected with the bottom plate, and an upper shaft which is located at the upper end of the main body and is used for installing the rotating body. A tool withdrawal groove is disposed between the lower shaft and the main body. A limiting shoulder is disposed between the upper shaft and the main body. The device is used for detecting the run-out errors of the basin mouth and end face of the flywheel cover relative to a reference surface and a technological hole, is simple in structure, is convenient to detect, is high in efficiency, is good in timeliness, is low in detection cost, and is suitable for the quick and accurate detection of a product on a production site.

Description

technical field [0001] The invention relates to a detection device for the beating of the basin opening and the end face of the flywheel housing. Background technique [0002] There are two forms of the existing flywheel shell basin mouth and end face runout detection: the first type is three-coordinate detection, which is characterized by high detection accuracy and high detection cost, but the disadvantage is low efficiency, which is not conducive to the production site. Rapid detection and finalization; the second type is a special detection device, which consists of two parts: the base assembly and the rotating arm (with dial indicator), which can meet the detection and finalization of the production site. The disadvantages are: 1. The base and the rotating arm The arm adopts the clearance fit of the hole shaft (the shaft of the rotating arm assembly rotates in the hole of the base assembly during operation), and the number of parts is large, and the system manufacturing...

[0002] There are two forms of the existing flywheel shell basin mouth and end face runout detection: the first type is three-coordinate detection, which is characterized by high detection accuracy and high detection cost, but the disadvantage is low efficiency, which is not conducive to the production site. Rapid detection and finalization; the second type is a special detection device, which consists of two parts: the base assembly and the rotating arm (with dial indicator), which can meet the detection and finalization of the production site. The disadvantages are: 1. The base and the rotating arm The arm adopts the clearance fit of the hole shaft (the shaft of the rotating arm assembly rotates in the hole of the base assembly during operation), and the number of parts is large, and the system manufacturing error is large; 2. When working, the rotating arm assembly needs to be separated from the base assembly Take it out, place it in an appropriate position, then put the workpiece in, and finally put it into the rotating arm assembly for inspection. The operation procedure is complicated. At the same time, because the rotating arm is too long, it is easy to cause deformation errors during daily placement, and it is easy to be damaged by foreign objects.
