Technical Field

[0001] The utility model relates to the technical field of measuring and checking tools, in particular to a measuring and checking tool for machining a differential housing of an automobile. Background Art

[0002] The differential case is the main external structure of the differential, usually a solid metal case, which contains four main gears: two planetary gears and two half-axle gears connected to the drive shaft. These gears work in the differential case to realize the differential function when the car is driving, and the case provides a protective shell for the internal gears and other components to prevent them from being damaged by the external environment. During the case processing, the size and accuracy of the automobile differential case need to be measured by a gauge. Most of the existing differential cases are directly placed on the test bench, and the differential case may not be effectively supported. If the fixed support points of the case are insufficient, shaking or displacement may occur during the measurement process, resulting in measurement errors; so we proposed a measuring gauge for automobile differential case processing to solve the above problems.

[0014] 2. According to the placement height of the differential housing, the rectangular telescopic sleeve drives the connecting plate to move downward along the second telescopic column to a suitable height through the drive of the second cylinder, so that the laser scanner continues to approach the differential housing to be measured, and then driven by the driver, the sliding block drives the second telescopic column to slide along the sliding groove and connect with the load-bearing platform, thereby performing a comprehensive scan of the differential housing. When the first side of the differential housing is measured, the rotating shaft drives the connecting block to rotate along the rotating ring sleeve through the drive, so that the differential housing is turned over, and the laser scanner drives the second telescopic column to move horizontally along the sliding groove through the sliding block for measurement, thereby performing a more comprehensive measurement.
