Gasket coaxial point-to-point remeasurement mechanism

Abstract

The invention discloses a gasket coaxial point-to-point retest mechanism, which comprises a mounting base, a guide rod cylinder, a mounting transition block, a gasket pressing block and a sensor mounting bottom plate, the sensor mounting bottom plate is used for placing the adjusting shim, and the shim pressing block is used for pressing the adjusting shim; the upper portion and the lower portion of the sensor installation bottom plate are each provided with a sensor installation piece, each sensor installation piece is provided with a displacement sensor, probes of the two displacement sensors are oppositely arranged and located on the two sides of the adjusting gasket respectively, the displacement sensors are pneumatic telescopic displacement sensors, and probes of the two displacement sensors extend and make contact with the adjusting shim so as to achieve the purpose of measurement. According to the remeasurement mechanism, through the arrangement of the two displacement sensors, self-reference coaxial measurement is achieved, no requirement for the height position exists, single-point up-down synchronous measurement is achieved, the structure is simple, system errors in the measurement process do not need to be considered, and the qualified rate is increased.

Description

technical field [0001] The invention relates to the field of gasket measuring equipment, in particular to a gasket coaxial point-to-point re-measurement mechanism. Background technique [0002] In the production process of the automobile gearbox, in order to ensure the accuracy of the product, it is necessary to measure the adjusting shim of the tapered roller bearing end of the automobile gearbox. [0003] The size of the bearing clearance directly affects the working quality of the gearbox. If the clearance is too large, the gear shaft will deviate from the center of the two bearing holes, resulting in the gears not meshing normally; if the clearance is too small, the working resistance of the shaft teeth will be increased and the bearing wear will be accelerated, resulting in Serious failure. Therefore, selecting the adjusting gasket and assembling it into the gearbox is the key to ensure that the reserved clearance of the tapered bearing meets the product design require...
