[0029] Among them, the adjusting unit is arranged below the bracket 1, the supporting plate 2 is arranged on the adjusting unit, the conveyor 3 is placed below the bracket 1, a plurality of the clamping units are arranged in sequence below the supporting plate 2, the control panel 4 is arranged on one side of the bracket 1, the five arc tracks 6 are all fixedly connected to the supporting plate 2 and are distributed in sequence below the supporting plate 2, one end of the five driving arc plates 5 are respectively slidably connected to the corresponding arc tracks 6, the other ends of the five driving arc plates 5 are respectively fixedly connected to the corresponding first electric slide rails 7, and the clamping unit is arranged at the output end of the first electric slide rail 7. The conveyor 3 conveys the wheel hub to the bottom of the bracket 1, and then clamps the protective plug through the clamping unit. At this time, the adjustment unit is started to drive it to the top of the wheel hub bolt hole. The staff operates the control panel 4 to adjust the position of the clamping unit according to the bolt hole type of the wheel hub. The driving arc plate 5 slides on the arc track 6, driving the first electric slide rail 7 to rotate and adjust under the support plate 2, and then move the clamping unit to the top of the corresponding bolt hole. At the same time, the first electric slide rail 7 moves the position of the clamping unit back and forth to adapt to wheel hub diameters of different sizes.

[0030] Secondly, the second electric slide rail 8 is fixedly connected to the bracket 1 and is located below the bracket 1. The lifting cylinder 9 is fixedly connected to the output end of the second electric slide rail 8, and the output end of the lifting cylinder 9 is fixedly connected to the support plate 2. The camera 10 is fixedly connected to the support plate 2 and is located below the support plate 2. The second electric slide rail 8 is started to drive the support plate 2 to move, and the lifting cylinder 9 is started to drive the support plate 2 to move downward, so that the protective plug is close to the bolt hole. The camera 10 can take pictures of the bolt hole of the wheel hub and transmit the information to the control panel 4, so as to control the movement of the protective plug and align the placement position.

[0031] At the same time, the limiting cylinder 11 is fixedly connected to the output end of the first electric slide rail 7 and is located below the first electric slide rail 7. The rebound plate 12 is slidably connected to the limiting cylinder 11 and is located inside the limiting cylinder 11. The two ends of the spring 13 are respectively movably connected to the inner top wall of the limiting cylinder 11 and the rebound plate 12. The two supporting mechanisms are symmetrically arranged inside the limiting cylinder 11. The limiting cylinder 11 limits the protective plug. After the supporting plate 2 moves downward, the protective plug enters the limiting cylinder 11, pushing the rebound plate 12 upward, and the spring 13 is compressed. At this time, the resisting mechanism is started to clamp and fix the protective plug. Then, after moving to the top of the bolt hole, the resisting mechanism cancels the resisting, and the spring 13 drives the rebound plate 12 to rebound, pops out the protective plug, and places it on the bolt hole. When the protective plug pops out, the limiting cylinder 11 should be as close to the wheel hub bolt hole as possible and maintain it for 5-10 seconds to avoid the protective plug from bouncing repeatedly on the wheel hub and causing deviation.

When the motor 17 is started, it drives the rotating shaft 18 to rotate, drives the gear 19 to rotate, and meshes with the arc rack 20, so that the driving arc plate 5 slides on the arc track 6, drives the first electric slide rail 7 to rotate, and at the same time, the supporting arc plate 21 slides in the supporting annular groove 22 to maintain the stability of the first electric slide rail 7.

[0034] Finally, the material storage unit is arranged on one side of the conveyor 3; the placement seat 23 is arranged on one side of the conveyor 3, and the placement annular groove 24 is arranged above the placement seat 23.

[0035] When using a bolt hole protective plug placement device of the present embodiment, first, the support plate 2 is moved to the top of the placement annular groove 24, the lifting cylinder 9 is started, and at the same time, the first electric slide rail 7 adjusts its position so that the protective plug is aligned and enters the limiting cylinder 11, and then the loading is completed by abutting and fixing with the abutting mechanism; the conveyor 3 conveys the wheel hub to the bottom of the bracket 1, and at this time, the second electric slide rail 8 is started to drive the support plate 2 to move, and at the same time, the lifting cylinder 9 is started to drive the support plate 2 to move downward, so that the protective plug is close to the bolt hole, and the camera 10 The bolt holes of the wheel hub can be photographed and the information can be transmitted to the control panel 4, so as to control the movement of the protective plug and align the placement position; then the staff operates the control panel 4 to adjust the position of the clamping unit according to the type of the bolt hole of the wheel hub, the motor 17 is started, driving the rotating shaft 18 to rotate, driving the gear 19 to rotate, and meshing with the arc rack 20, the driving arc plate 5 slides on the arc track 6, driving the first electric slide rail 7 to rotate and adjust under the support plate 2, and then the limit cylinder 11 is moved to the top of the corresponding bolt hole, and at the same time The first electric slide rail 7 moves the position of the limiting cylinder 11 forward and backward to adapt to wheel hub diameters of different sizes; finally, the abutting mechanism cancels the abutting limit, and the spring 13 drives the rebound plate 12 to rebound, popping out the protective plug and placing it on the bolt hole; when the protective plug pops out, the limiting cylinder 11 should be as close to the wheel hub bolt hole as possible and keep it for 5-10 seconds to avoid the protective plug from bouncing repeatedly on the wheel hub and causing deviation. After the protective plug is completely placed and stabilized, the limiting cylinder 11 can be moved up, thereby completing the placement of the protective plug; through the above-mentioned structural setting, it can be adjusted according to the type of wheel hub.
