Description

Technical Field

[0001] The utility model relates to the technical field of processing automobile parts, in particular to a three-dimensional calibration mechanism for automobile air suspension components. Background Art

[0002] Since its birth in the mid-19th century, air suspension has gone through a century of development and has undergone many changes, such as "pneumatic spring-airbag composite suspension-semi-active air suspension-central air suspension (i.e. ECAS electronically controlled air suspension system)". It was not until the 1950s that it was applied to trucks, buses, cars and railway cars. At present, almost all high-end buses abroad use air suspension, and the proportion of heavy trucks using air suspension has reached more than 80%. The application of air suspension on light vehicles is also increasing rapidly. Some cars are also gradually installed and used with air suspension. On some special vehicles (such as instrument vehicles with high shockproof requirements, ambulances, special military vehicles and container transport vehicles with requirements, etc.), the use of air suspension is almost the only choice.

[0003] The air suspension assembly has a bladder. Different models of cars use different bladders, and the front and rear bladders of the same car may also be inconsistent. The bladder needs to be tested and qualified during the production process before it can be used.

[0004] The existing testing equipment makes a precision-machined calibration sample for each model of product as the first calibration piece for the equipment to switch products. The problem is the high cost. The production and third-party measurement cost of each model of calibration piece is about 6,000 yuan. At the same time, the calibration piece needs to be placed manually when calibrating the equipment. This method is cumbersome to operate and use, and the calibration piece is too heavy, and there is a risk of damaging the optical measurement system during the operation. Utility Model Content

[0017] Furthermore, a reflective optical fiber for detecting the presence of the capsule skin is also arranged on the bracket, so that subsequent detection can be carried out in time after the capsule skin is placed.
