Abstract

The invention relates to the technical field of flatness measurement, and discloses a flatness measuring mechanism for an automobile rear silencer flange, which comprises a contact rod, a pressing connecting rod is slidably mounted above the contact rod, a transmission rod is slidably mounted above the pressing connecting rod, the transmission rod is slidably mounted on a lower fixing sleeve, a middle rotating sleeve is rotatably mounted above the lower fixing sleeve, an upper pressing movable sleeve is fixedly installed in the middle of the middle rotating sleeve, an upper rotating sleeve is rotationally installed above the upper pressing movable sleeve, a fixed spring is fixedly installed above the upper pressing movable sleeve, and a flange body is fixedly installed below the contact rod. According to the flatness measuring mechanism of the automobile rear silencer flange, the contact rod moves upwards, the contact rod drives the pressing connecting rod to move upwards, the pressing connecting rod drives the transmission rod to move upwards, the upper pressing sleeve is extruded, the uneven position is recorded, and therefore the flatness is automatically detected, and labor waste is not easily caused, and the energy-saving and environment-friendly effects are achieved.

Description

technical field [0001] The invention relates to the technical field of flatness measurement, in particular to a flatness measurement mechanism for a rear muffler flange of an automobile. Background technique [0002] With the rapid development of economy and technology, the production automation of automobile products has also been developed at a high speed. The automobile muffler is a part used to reduce the noise generated by the engine of the motor vehicle. Since the length difference between the two pipes is equal to the The half of the wavelength of the sound wave makes the two rows of sound waves interfere and cancel each other when they are superimposed to weaken the sound intensity and reduce the sound, thus playing the effect of noise reduction. Now the flange of the rear muffler of the automobile exhaust system is welded on the On the pipe of the rear muffler, the plane is easily deformed after welding, and its flatness needs to be checked. [0003] At present, th...
