Description

Technical field:

[0001] The utility model relates to the technical field of wheel hub manufacturing equipment, and more specifically to a grabbing and conveying device for online wheel hub balance detection. Background technology:

[0002] The wheel hub is a cylindrical metal part with the inner profile of the tire supporting the tire, and the center is mounted on the shaft. There are many types of wheel hubs according to diameter, width, molding method, and material. The wheel hub generally includes the rim, spokes, flange, bead seat, etc.

[0003] After the existing wheel hub is machined, it needs to be tested for its balance. In the existing production process, the wheel hub is generally placed in the input frame, and the roller on the conveying frame rotates to convey the wheel hub along the conveying frame to the testing platform. Then, it is manually taken off the conveying frame and placed on the testing platform. The manual operation efficiency is low, and the weight of the wheel hub is heavy, so the manual labor is also large during transportation, and the effect is not ideal;

[0004] Moreover, after the inspection is completed, the wheel hub needs to be manually placed back on the conveyor frame, and then transported to the subsequent process through the conveyor frame. During manual inspection, the wheel hub on the conveyor frame is still being transported, and generally its conveying speed is slow to ensure that after the previous wheel hub is inspected, it is placed on the conveyor frame before the material is taken for inspection. However, when the inspector operates slowly, the wheel hub that has not been inspected on the conveyor frame may be directly transported to the subsequent process, affecting its inspection effect.
