Abstract

The invention discloses an NVH offline detecting device for a car gearbox. The NVH offline detecting device comprises an NVH collector, a mounting plate connected with the NVH collector, a translation mechanism, an angle adjusting mechanism and a tightening air cylinder and is characterized in that the translation mechanism is provided with a positioning pin and a clamping mechanism to perform repeated position positioning and fixing; the NVH collector can be in contact with the to-be-detected gearbox under the action of the tightening air cylinder and reliably collects the vibration signal of the to-be-measured gear box. The NVH offline detecting device has the advantages that the mounting problem of the collector of the NVH offline detecting device is solved, the space positions the NVH collector are flexible and varied, and the device is well adaptive to measuring position requirements.

Description

technical field [0001] The invention relates to an NVH off-line detection device, in particular to an NVH off-line detection device for an automobile gearbox. Background technique [0002] At present, the off-line inspection of gearboxes is becoming increasingly automated, and gearbox products tend to be diversified. During the off-line inspection of the gearbox, in order to be able to perform NVH off-line inspection on the gearbox, it is necessary to install an NVH collector on the gearbox housing. At present, the installation of the NVH off-line detection sensor of the automobile gearbox is manually installed, which is inefficient, and the change of the manual installation position will affect the measurement results. Contents of the invention [0003] In order to solve the deficiencies in the prior art above, the present invention provides a NVH off-line detection device for automobile gearboxes. [0004] In order to realize the purpose of the present invention, the p...
