[0034] The utility model is further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 3 As shown, the utility model provides a protective plug removal mechanism, including a base 1. A collaborative robot 2 is arranged on the base 1, and a plug removal clamp 4 is arranged at the execution end of the collaborative robot 2. A positioning mechanism 5 is arranged on the base 1 for positioning the wheel hub. A clamping mechanism 6 is arranged on the base 1 for clamping and fixing the wheel hub. A guide groove 3 is also arranged on the base 1.

[0036] Collaborative robot 2 uses a domestic collaborative robot to complete the plug removal work. The collaborative robot is equipped with six axes. After the wheel hub enters the working position, the positioning machine completes the positioning of the ground chain rod. The plug removal gripper uses a gripper cylinder + customized fixture. The fixture can lift the upper edge of the plug to complete the plug removal action. Robot model xMate CR7: arm span 998mm, load 7kg.

[0037] The specific structure of the plug removal clamp 4 includes a clamp cylinder 401, and a clamp 402 is provided on the clamp cylinder 401. A U-shaped groove 403 is provided on the clamp 402. After the plug removal clamp 4 is closed, the middle part is a U-shaped groove structure, which lifts up the protective plug. The lifting is used instead of clamping here to prevent the position of the protective plug from deviating from the theoretical position when the wheel hub is not accurately positioned. If the clamping structure is used, the protective plug will scratch the paint surface of the wheel hub.

[0038] The specific structure of the positioning mechanism 5 includes a bracket 501, and the bracket 501 is arranged on the base 1. The side rail 502 is arranged at the upper end of the bracket 501, and the two ends of the side rail 502 are provided with a bevel 504. The side rail 502 is connected and fixed to the bracket 501 through a long hole 503. The spacing between the side rails 502 is adjustable, so as to adapt to the ground chain rods of wheel hubs of different sizes.

[0039] The specific structure of the clamping mechanism 6 includes a first clamping arm 602 and a second clamping arm 603 that can rotate relative to each other. A first gear 604 is provided on the first clamping arm 602, and a second gear 605 is provided on the second clamping arm 603. The first gear 604 and the second gear 605 are meshed and driven. The first clamping arm 602 is driven by a clamping cylinder 601. The clamping mechanism 6 drives a group of clamping arms through the clamping cylinder 601 to realize the opening and closing action. The clamping arms on both sides change the rotation direction through gears. The clamping arms are designed as a V-shaped structure to improve the positioning stability. This structure has high positioning accuracy and large clamping force, which can ensure positioning accuracy.

[0040] The clamping cylinder 601, the first clamping arm 602 and the second clamping arm 603 are arranged on the movable plate 606, and the movable plate 606 is slidably arranged on the fixed plate 608. An adjusting bolt 607 is arranged between the movable plate 606 and the fixed plate 608. The position of the clamping mechanism 6 can be adjusted by turning the adjusting bolt 607, so as to adapt to the ground chain rods of the wheel hubs of different sizes and structures.

[0041] The working steps are as follows: the ground chain runs to the working position of the equipment, that is, the position of the positioning mechanism 5 - the clamping mechanism 6 clamps the ground chain rod - the collaborative robot 2 takes the plug - after the collaborative robot 2 takes the plug, it moves the plug to the blowing position to blow the plug, and after blowing, the plug is placed in the guide groove 3, and the guide groove 3 transports the plug to the collection box.

[0042] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
