Engine cover surface difference accurate adjustment cushion block and adjustment method

Abstract

The invention discloses an engine cover surface difference accurate adjustment cushion block and an adjustment method. The engine cover surface difference accurate adjustment cushion block and an adjustment method are used for assisting the measurement of the surface difference value between an engine cover and fenders on a vehicle welding adjustment line, and comprise an upper cushion block and a lower cushion block which are coaxially arranged, and the upper part of the upper cushion block is provided with a magnet for adsorbing the engine cover; and the upper cushion block and the lower cushion block are connected through an elastic guide assembly, the lower cushion block can move in the axial direction of the lower cushion block and can rotate along the central axis of the lower cushion block, and a height adjusting assembly capable of converting circumferential rotation movement of the lower cushion block into axial linear movement is arranged between the upper cushion block and the lower cushion block. The engine cover surface difference accurate adjustment cushion block and the adjustment method can be used on the welding adjustment line in the technological manufacturing process of an automobile, play a role of a gauge and a tool, and play an important role in off-line and quality control and monitoring of the automobile on the welding adjustment line.

Description

technical field [0001] The invention discloses an adjustment cushion block, which belongs to the technical field of vehicle welding line inspection tool detection, and specifically discloses an accurate adjustment cushion block and an adjustment method for machine cover surface difference. Background technique [0002] In the hood product design of the car, there are two height-adjustable rubber pads, which are used to adjust the surface difference between the hood and fender of the whole vehicle, correct the dimensional deviation caused by various manufacturing processes, and ensure the delivery to customers. Product aesthetics up to standard. However, the adjustment amount of the rubber pad has a certain range, so in mass production, strict quality control of each process is required to prevent the deviation from exceeding the adjustment amount of the rubber pad. In the process control, the vehicles sent to the painting by the welding adjustment line need to be installed ...

AI Technical Summary

Problems solved by technology

Advantages and disadvantages of method 1: a certain proportion of vehicles cannot be qualified due to manufacturing deviations of hoods and fenders, resulting in inaccurate determination of clearances; advantages and disadvantages of method 2: manufacturing deviations can be compensated to ensure that the hoods and fenders are qualified Check clearance condition

The above prior art cannot realize the quantitative measurement function
