AI Technical Summary
When a robotic arm places a workpiece directly onto a processing device, the workpiece may shift, affecting processing quality and accuracy.
Design a positioning mechanism including a support frame and circumferentially spaced limiting components. The limiting components include a linear drive and a pushing structure for abutting against the periphery of the workpiece to ensure that the workpiece remains in a fixed position during processing.
The circumferential positioning of the pusher structure prevents workpiece displacement, improves the stability and accuracy of the machining process, and is applicable to workpieces of different sizes, thus expanding its versatility.

Abstract
Claims
1. A positioning mechanism, characterized by, include: A support frame having a processing position for placing a workpiece; Multiple limiting components are provided, and the multiple limiting components are arranged around the processing position and spaced apart in the circumferential direction. Each limiting component has a pushing structure and a linear drive member. The linear drive member is driven to the pushing structure to drive the pushing structure to slide on the support frame toward the processing position so as to abut against the periphery of the workpiece.
2. The positioning mechanism of claim 1, wherein, The positioning mechanism further includes a sliding component, and the pushing structure is slidably connected to the support frame through the sliding component.
3. The positioning mechanism of claim 2, wherein The sliding assembly includes a slider and a slide rail. Each of the pushing structures has at least one slider at its bottom. The slide rail is located on the support frame, and the slider is slidably connected to the slide rail.
4. The positioning mechanism of claim 3, wherein The support frame is provided with a sliding groove, the slide rail is located in the sliding groove, and the length of the sliding groove is greater than that of the slide rail.
5. A positioning mechanism according to any one of claims 1 to 4, wherein The jacking structure includes a connecting plate and a baffle. The connecting plate is connected to the output end of the linear drive, and the baffle is installed at the end of the connecting plate away from the linear drive.
6. The positioning mechanism of claim 5, wherein, The baffle has rounded corners on the side facing the processing position.
7. The positioning mechanism of claim 6, wherein The jacking structure also includes at least one limiting plate, which is located above the baffle and is detachably connected to the baffle.
8. The positioning mechanism of claim 5, wherein, The limiting component also includes a mounting structure, the linear drive component is driven to the mounting structure, and the mounting structure is detachably connected to the connecting plate.
9. The positioning mechanism as described in claim 8, characterized in that, The connecting plate has a slot on the side away from the baffle. The mounting structure includes a mounting plate and connectors at both ends of the mounting plate. The connectors have snap-fit parts that snap into the slots.
