Wheel disc outer edge flatness detection equipment for flywheel machining

Abstract

The invention discloses wheel disc outer edge flatness detection equipment for flywheel machining, and relates to the technical field of automobile part detection. The equipment a base, a flatness detection mechanism, a positioning clamping pin, a self-locking pin pulling mechanism and an expansion sleeve, and an oscilloscope is arranged on one side of the base. According to thewheel disc outer edge flatness detection equipment for flywheel machining, by arranging the flatness detection mechanism, the technical blank that an existing device cannot complete flatness detection of the outer edgeof a flywheel disc in the prior art is perfectly filled up, flatness detection is visually, easily and conveniently conducted on the outer edge of the flywheel disc through a simple mechanical structure, the shape of a detection roller on one side of the mechanism is attached to the outer edge of the flywheel disc, the flywheel wheel disc is arranged between an upper pressing plate and a lower pressing plate to achieve self-rotation, if the outer edge of the wheel disc is uneven, the detection roller transmits vibration to a first spring through a connecting rod, vibration signals are transmitted to an oscilloscope through a waveform sensor, operation is easy and convenient while sensitivity is high, and the overall maintenance cost of the mechanism is low.

Description

technical field [0001] The invention relates to the technical field of auto parts detection, in particular to a device for detecting the flatness of the outer edge of a wheel disc for flywheel processing. Background technique [0002] The flywheel assembly is mostly used in high-speed and high-power diesel engines, and is an important part of the diesel engine starting system; the flywheel is composed of the internal disc-shaped flywheel disc and the outer ring gear set on the outer edge of the flywheel disc. Interference fit, so in order to meet the assembly requirements of the wheel disc and the outer ring gear, the wheel disc of the automobile flywheel must ensure that the surface smoothness of the outer edge is high enough during processing, so that it can meet the requirements of the outer ring gear during assembly. Matching requirements; make the assembled automobile flywheel meet the production requirements, otherwise if there are protrusions on the outer edge surface...

Problems solved by technology

[0002] The flywheel assembly is mostly used in high-speed and high-power diesel engines, and is an important part of the diesel engine starting system; the flywheel is composed of the internal disc-shaped flywheel disc and the outer ring gear set on the outer edge of the flywheel disc. Interference fit, so in order to meet the assembly requirements of the wheel disc and the outer ring gear, the wheel disc of the automobile flywheel must ensure that the surface smoothness of the outer edge is high enough during processing, so that it can meet the requirements of the outer ring gear during assembly. Matching requirements; make the assembled automobile flywheel meet the production requirements, otherwise if there are protrusions on the outer edge surface, the assembly quality will not be guaranteed

[0003] The existing flywheel assembly processing equipment has common problems as follows: in the prior art, there is no special equipment for detecting the outer edge of the wheel disc of the flywheel in the detection and positioning mechanism to detect the smoothness of the outer surface of the wheel disc, so it is easy to cause subsequent teeth The assembly error caused by the assembly of the ring and the flywheel disc, too high equipment error will easily lead to the unstable operation of the finished flywheel assembly, which greatly affects the service life of the finished workpiece, so there is an urgent need for a special test for the outer edge of the flywheel wheel Equipment to ensure the assembly accuracy of the flywheel assembly
