[0042] Working principle:

[0043] I. Power transmission and rotational clamping

[0044] The servo motor 2 provides the power source, and its output end is fixedly connected to the coupling 3. After the servo motor 2 is started, the power is transmitted to the lower disc 4 through the coupling 3, and the coupling 3 ensures the smoothness and accuracy of the power transmission.

[0045] The lower disc 4 transmits the power to the upper disc 6 through the belt 5 to achieve the power transmission.

[0046] The upper disc 6 drives the left clamping shaft 7 to rotate. The left clamping shaft 7 rotates in the left positioning arm 8 to prepare for clamping the hardware parts.

[0047] II. Clamping and positioning operation

[0048] The cylinder 13 pushes the right moving arm 10 to slide on the guide rail 9. The cylinder 13 provides the thrust to make the right moving arm 10 move along the guide rail 9 towards the direction close to the left clamping shaft 7.

[0049] The right clamping shaft 11 in the right moving arm 10 works together with the left clamping shaft 7 to clamp and position the hardware parts.

[0050] The fixed block 14 connects the movable end of the cylinder 13 and the right moving arm 10 to ensure that the thrust of the cylinder 13 can be effectively transmitted to the right moving arm 10.

[0051] III. Debris collection function

[0052] The collection box 12 is used to collect debris generated during the processing. The magnet 15 ensures the stable adsorption of the collection box 12.

[0053] The left positioning arm 8 is made of iron, which is convenient for the adsorption of the collection box 12. The left positioning arm 8 provides an adsorption position for the collection box 12.

[0054] In summary, through the collaborative action of various components, the positioning device for hardware part processing realizes the precise positioning of hardware parts and the function of collecting debris during the processing.

[0055] As Figure 1 shown, in some embodiments, the lower wheel disc 4 and the upper wheel disc 6 are provided with tooth grooves, which are adapted to the belt 5 to prevent slipping; with the adaptation of the tooth grooves and the belt 5, it can ensure that the power is stable and reliable during the transmission process from the servo motor 2 through the coupling 3, the lower wheel disc 4, the belt 5, the upper wheel disc 6, and then to the left clamping shaft 7, providing continuous and accurate power support for the clamping and positioning and rotary processing of hardware parts.

[0056] As Figure 1 shown, in some embodiments, the lower wheel disc 4 is simultaneously rotatably connected to one side of the left positioning arm 8; it provides additional support and stability for the entire power transmission system.

[0057] As Figure 1 shown, in some embodiments, the left clamping shaft 7 and the right clamping shaft 11 are on the same axis for processing and positioning the hardware parts; when the cylinder 13 pushes the right moving arm 10 to slide on the guide rail 9, the right clamping shaft 11 approaches the left clamping shaft 7. Since they are on the same axis, it can accurately align with the center position of the hardware part to achieve precise positioning.

[0058] As Figure 1 shown, in some embodiments, the fixing block 14 is inlaid and installed on the inner wall of the right moving arm 10; this installation method can save space and make the structure of the entire device more compact. When the right moving arm 10 slides on the guide rail 9, it needs to maintain a small volume and flexible mobility. The fixing block 14 is inlaid on the inner wall and does not protrude from the surface of the right moving arm 10, avoiding interference with other components and making the appearance of the entire device more neat and beautiful.

[0059] As Figure 3 shown, in some embodiments, a partition 16 is installed in the middle of the collection box 12; this facilitates the subsequent processing and recycling of the collected items and improves work efficiency.

[0060] In some embodiments, the left positioning arm 8 is made of iron and the right moving arm 10 is made of stainless steel. The iron one can provide an installation position, and the stainless steel one is not adsorbed by the magnet 15.
