Technical Field

[0001] This utility model relates to the field of quality inspection tooling technology, specifically a bearing quality inspection tooling. Background Technology

[0002] In the bearing manufacturing industry, quality inspection is a crucial step in ensuring the performance and lifespan of bearing products. It requires rigorous testing of core indicators such as dimensional accuracy, smooth rotation, and surface defects. Currently, mainstream bearing quality inspection methods in the industry suffer from the following pain points: existing inspection fixtures are mostly single-station designs, capable of fixing and inspecting only one bearing at a time. After inspection, the old bearing must be manually disassembled and the new bearing installed, resulting in a significant waiting period. Especially in mass production scenarios, the single-station inspection mode cannot match the production line's pace, leading to low overall quality inspection efficiency, potential bearing product accumulation, and increased production cycles and costs. Therefore, new technical solutions are needed to address these issues. Utility Model Content

The ball bearings 144 in the rotating cavity 143 of the inner wall of the shaft seat 14 a141 and shaft seat b142 fit against the outer wall of the rotating rod 11 to reduce rotational friction. The operator can apply force through the arc-shaped notch 12 on the edge of the rotating disk 3 to push the rotating disk 3 to rotate around the rotating rod 11, switching the bearing fixing cylinders 17 containing the bearings to the inspection position below the protective cover 2. The electric push rod 4 at the top of the protective cover 2 is activated, driving the output end connected to The lifting frame 9 moves up and down along the slide rail 10 on the inner wall of the protective cover 2. Through the precise control of the electric push rod 4, the rotary motor 7, the inspection frame 6, and the inspection head 8 at the bottom of the lifting frame 9 are driven to rise and fall synchronously until the inspection head 8 moves to the inspection height that matches the surface of the bearing to be inspected. After the inspection of a single station is completed, the electric push rod 4 drives the lifting frame 9 to lift and reset the inspection head 8. The operator pushes the rotary table 3 again to switch the next station with the bearing to be inspected to the area below the inspection head 8. The above steps are repeated until all the bearings at the four stations have been inspected. Finally, the inspected bearings are removed, completing one round of quality inspection.
