Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a positioning device for a vehicle body covering part. Background Art

[0002] At the current stage of vehicle body trial production, if the gap is too large or too small or the surface difference is uneven, it will affect the appearance and performance of the vehicle and affect the sealing and sound insulation of the vehicle. If the gap is unreasonable, it may cause problems such as water leakage, air ingress or excessive noise, affecting the driving experience and safety.

[0003] In the current car body trial production stage, the car body covering parts are supported and positioned and installed by using positioning auxiliary devices. However, in actual assembly, due to the existing positioning auxiliary devices, the commonly used method is to insert and cooperate with the body covering parts by the positioning pins set on the top of the positioning auxiliary devices, so as to achieve installation and fixation, and then use the detection device to detect the gap and flushness of the body covering parts. However, the defects are also obvious: since the positioning auxiliary device uses a single top positioning pin for positioning, the center of gravity of the body covering parts is unstable, resulting in the detection accuracy of the gap and flushness of the body covering parts. Secondly, the existing positioning auxiliary device uses a single supporting effect on the bottom of the body covering part, and cannot provide the body covering part with a stable clamping force, resulting in poor overall stability of the body covering part. During on-site operation, manual cooperation is often required, with low work efficiency and high manpower and time costs.

[0004] The present application provides a vehicle body cover positioning device, which supports and positions the vehicle body cover through the cooperation of a left positioning support assembly and a right positioning support assembly, and further provides a certain clamping force to the vehicle body cover through the cooperation of the left positioning support assembly and the right positioning support assembly, thereby ensuring the positioning accuracy of the vehicle body cover as a whole, improving the detection accuracy of gaps and face differences, and having the advantages of high efficiency and low cost.
