Description
Technical Field
[0001] The utility model relates to the technical field of measuring tools, in particular to a distance measuring tool used for a differential housing of an automobile. Background Art
[0002] The differential is an important component in a car. It is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. Its function is that when the car is turning or driving on uneven roads, the differential can adjust the speed difference between the left and right wheels so that the left and right wheels roll at different speeds, thereby ensuring that the drive wheels on both sides perform pure rolling motion. It is mainly composed of planetary gears, planetary wheel carriers (differential housings), half-axle gears and other parts. The structure and processing accuracy of its housing directly affect the normal operation of the differential.
[0003] After searching, China Patent Publication (Announcement) No. 202320531367.0 discloses a vehicle differential case diameter measuring jig, which uses a gripping rod, and a connecting sleeve is fixedly connected to one side wall of the gripping rod, and a through hole is opened between the center positions of the front and rear side walls of the connecting sleeve, and a connecting shaft is rotatably connected in the through hole, and a laser measuring mechanism is arranged on the front side of the connecting shaft, and the laser measuring mechanism includes a double-headed spring seat, and the double-headed spring seat is fixedly connected to the front side wall of the connecting shaft, and a laser rangefinder is fixedly installed in the middle position of the front side wall of the double-headed spring seat, and the laser A laser transmitting head is respectively arranged at the center position of the upper and lower side walls of the rangefinder, and a shading plate is respectively arranged on the upper and lower sides of the laser rangefinder to complete the detection of the differential distance. Although the above patent completes the detection of the diameter, the error is very large. In order to ensure the reduction of the error, the differential clamping plate is used for detection to reduce the error and the distance of each part of the differential housing can be measured at the same time, thereby reducing the error. In order to prevent the accumulation of dust and increase the error during the next detection, a movable fan is set to clean the dust. Therefore, it is necessary to design a distance gauge for the automobile differential housing. Utility Model Content
