Description

Technical Field

[0001] The utility model belongs to the technical field of automobile manufacturing, and in particular relates to a measuring device for a transmission chain of an automobile transfer case. Background Art

[0002] The automobile transfer case is a necessary component assembly for four-wheel drive vehicles. The assembly quality of the automobile transfer case is directly related to the quality of the entire vehicle. Therefore, the length of the transmission chain in the assembly of the automobile transfer case is the key to the occurrence of transfer case noise. The chain is a key link in the assembly of the automobile transfer case that must control its quality. Since the length of the chain in the transfer case will cause noise and damage the transmission gear during the transmission process, the chain must be measured before installation and its length must be within the tolerance range before it can be used. Therefore, accurate measurement and selection must be carried out before assembly to ensure the overall quality of the transfer case. The automobile transfer case is a component on four-wheel drive vehicles during use. Its main function is to distribute the power of the engine and output the power to the rear axle or to the front / rear axle at the same time. The quality of the transfer case directly affects the stability of the four-wheel speed when the four-wheel drive is used, and the transfer case If the transfer case quality is not good, the output speed will be out of sync. If the four wheels are out of sync, the whole vehicle will vibrate and cannot be driven normally. Therefore, each component must be accurately measured during the transfer case assembly process. It can be assembled to the transfer case only when it reaches the corresponding tolerance. This equipment is to measure the gap length of the key component of the transfer case, the "drive chain". The gap length of the chain must have a specified tolerance range during assembly. The previous working method was to use manual pressure to measure the gap length, which has poor accuracy and inconsistent data. The unqualified rate of assembled products is relatively high, and manual measurement time is long. Therefore, in order to improve product quality and production efficiency, this automobile transfer case clutch chain installation rapid measurement device has been developed. At present, this device has been used in assembly, with obvious results. The measurement working time for each operation has been reduced from the original 6 minutes to less than 1 minute, with obvious results.
