Description

Technical Field

[0001] This utility model relates to the field of automatic bushing detection technology, specifically to an automatic detection device for the inner and outer diameters and height of bushings. Background Technology

[0002] A bushing is typically a tubular or sleeve-shaped part made of metal, plastic, rubber, or composite material, and is installed between two relatively moving parts (such as a shaft and a bore, a bearing and a housing bore, etc.).

[0003] For example, the utility model patent with publication number CN221484404U discloses a detection device for a subframe bushing, including a base plate with a base for mounting the bushing. After the bushing is installed on the base, the bottom surface of its inner sleeve contacts the base. Above the base plate, there is also a height limiting block with a height limiting plane and a width limiting side plate with a width limiting vertical surface. When the bushing is installed on the base, the base and the height limiting block can move relative to each other until the height limiting plane contacts the groove on the top surface of the bushing, and the base and the width limiting side plate can move relative to each other until the width limiting vertical surface contacts the outer side of the bushing. The bushing inspection device proposed in this utility model, after determining the installation position of the bushing, utilizes the relative movement of the bushing and the inspection surface and its structure to complete the inspection of the bushing height and outer diameter in one process. The inspection efficiency is high and the results are accurate. However, there is a problem that when inspecting the height and inner and outer diameters of each bushing, each bushing needs to be clamped and limited, which will cause a certain amount of time to be spent in the clamping and limiting process, ultimately reducing the efficiency of the same batch of bushings in the inspection process. To address this, we propose an automatic inspection device for the inner and outer diameters and height of bushings. Utility Model Content

Each slider 68 moves a positioning pin 69. During the movement of the two symmetrical positioning pins 69, they contact the inner and outer end faces of the bushing. The distance between the two positioning pins 69 can be measured and recorded using an external ruler. When the data on one bushing is measured... Once completed, the first stepper motor 52 can be started. The output of the first stepper motor 52 drives the first rotating shaft 53 to rotate. The first rotating shaft 53 drives the incomplete gear 54 to rotate. The incomplete gear 54 drives the external gear ring 55 to rotate intermittently in the opposite direction. At this time, the external gear ring 55 drives the rotating plate 56 to rotate at a fixed angle.
