[0002] In the field of automobile manufacturing, in order to ensure the safe use of automobiles after leaving the factory, it is necessary to strictly control the assembly accuracy of the produced automobile parts to ensure the stroke installation of the automobile and reduce the accident rate of the vehicle; and the coaxiality installation of automobile parts Accuracy plays an important role in the driving safety of the vehicle. The two ends of the various transmission shafts of the car are generally installed by setting the journal and the bushing. During the processing, due to the large machining force on the journal, for The journal of machining error is easy to appear because the coaxiality of the shaft itself is not high, which leads to safety problems in later use

The invention discloses a coaxiality detecting device for processing automobile parts. The device comprises a measuring cylinder and a necking mechanism which is installed in the measuring cylinder and is used for reducing the inner diameter of a precession cylinder. The necking mechanism comprises multiple necking components, and each group of necking components comprises a first hinge rod, a second hinge rod and a driving rod. The front end of the first hinge rod is hinged to the side wall of a strip-shaped groove. Two ends of a hinge shaft of the second hinge rod and the driving rod are embedded into a guide groove arranged at the side wall of the strip-shaped groove and is in a single degree of freedom sliding cooperation with the precession cylinder along an axial direction, the coaxiality detection and reading are realized through a cylindrical spring, a pressure sensor and a display unit, at the same time, the coaxiality of a narrow space can be detected, the structure is simple, a detection result is convenient to read, and the detection precision is high.
Description
technical field [0001] The invention relates to a testing tool for auto parts, in particular to a coaxiality testing device for processing auto parts. Background technique [0002] In the field of automobile manufacturing, in order to ensure the safe use of automobiles after leaving the factory, it is necessary to strictly control the assembly accuracy of the produced automobile parts to ensure the stroke installation of the automobile and reduce the accident rate of the vehicle; and the coaxiality installation of automobile parts Accuracy plays an important role in the driving safety of the vehicle. The two ends of the various transmission shafts of the car are generally installed by setting the journal and the bushing. During the processing, due to the large machining force on the journal, for The journal of machining error is easy to appear because the coaxiality of the shaft itself is not high, which leads to safety problems in later use. [0003] Therefore, in order to...
