The two busbars 94 are set open on one side away from the testing platform 1, and the opening formed by the two busbars 94 and the feeding slot 95 form a funnel-shaped feeding channel. During actual use, the workpiece to be inspected is placed in an open position, and the conveying motor 93 is started to drive the conveyor belt 91 to move, which can drive the workpiece to be inspected to move toward the inspection table 1. After the workpiece to be inspected abuts against the convergence plate 94, it is transported by the conveyor belt 91 and is collected one by one into the loading slot 95, and is driven by the conveyor belt 91 to move toward the inspection table 1. At this time, the clamping assembly 5 can be used to clamp the workpiece to be inspected in the loading slot 95 closest to the inspection table 1 one by one, thereby completing the loading of the workpiece to be inspected. During the roundness detection process, the conveying motor 93 stops. After the detection is completed, the clamping assembly 5 drives the workpiece to move to the conveyor belt 91 on the other side of the inspection table 1. At this time, the conveying motor 93 is started again to drive the conveyor belt 91 to move, so that the workpiece to be inspected can be moved one by one for loading.

[0048] The implementation principle of a feeding device for roundness detection equipment proposed in the embodiment of the utility model is as follows:

[0049] In actual use, the workpiece to be inspected is placed at the open position at the left end of the two convergence plates 94 on the conveyor belt 91, and the conveying motor 93 is started to drive the conveyor belt 91 to move, which can drive the workpiece to be inspected to move toward the inspection table 1.

At this time, the drive motor 71 is started to drive the driving screw 72 to rotate, and then the mounting part 4 is driven to move toward the convergence plate 94. When the mounting part 4 moves above the loading slot 95, the lifting motor 61 is started to drive the mounting rod 3 to move downward. At the same time, the clamping assembly 5 is used to clamp the workpiece to be inspected in the loading slot 95 closest to the inspection table 1, and then the lifting motor 61 drives the mounting rod 3 to move upward, and the driving motor 71 is used to drive the driving motor 71. Drive the mounting part 4 to move toward the three-jaw chuck 11. When the workpiece to be inspected moves above the three-jaw chuck 11, the lifting motor 61 drives the mounting rod 3 to move downward, and the clamping assembly 5 is released to place the workpiece to be inspected in the placement bin 15 in the three-jaw chuck 11. The roundness detection of the workpiece can be started by clamping the workpiece to be inspected by the three-jaw chuck 11. After the inspection is completed, the three-jaw chuck 11 is released, and the clamping assembly 5 clamps the workpiece to be inspected. The lifting motor 61 is started to drive the mounting rod 3 to move upward, and the drive motor 71 is started to drive the mounting part 4 to move in the direction away from the manifold 94. The workpiece that has been inspected is placed on the conveyor belt 91 on the other side of the inspection table 1, that is, the entire roundness detection process of a workpiece is completed. Repeat the above steps to complete the roundness detection of each workpiece one by one.
