The surface of the adsorption portion 11 is provided with air holes. It is pointed out here that the negative pressure structure is an exhaust fan with a filter screen at the air inlet, and the exhaust fan draws air from the space where the adsorption portion 11 is located to facilitate fitting the wheel cover. The supporting special-shaped ring 6 is arranged on the outer edge of the adsorption portion 11, and the contour of the supporting special-shaped ring 6 is adapted to the contour of the lower edge of the wheel cover. The supporting special-shaped ring 6 and A gap is left at the lower edge of the wheel cover, so that after assembly, the lower edge of the wheel cover is raised on the supporting special-shaped ring 6. After the clamping structure 4 is pressed, it can be ensured that the wheel cover can be installed in place when the supporting special-shaped ring 6 exists. The mounting portion 12 is provided with a special-shaped track 7, and the contour of the special-shaped track 7 matches the contour of the supporting special-shaped ring 6. The negative pressure structure is arranged in the shell 5 to provide negative pressure for the air holes of the adsorption portion 11. The adsorption portion 11 and the mounting portion 12 are fixedly connected by a mounting rod located in the center, and the mounting rod avoids the transmission rod 10. The tool module 8 is slidably arranged on the special-shaped track 7 and trims both sides of the lower edge of the wheel cover. The motor 9 is arranged in the shell 5 and drives the tool module 8 to slide along the special-shaped track 7 through the transmission rod 10.

[0026] The special-shaped track 7 includes a first track 13 and a second track 14 of the same structure. The first track 13 and the second track 14 are arranged in parallel, and a channel 15 is arranged on the mounting portion 12 between the first track 13 and the second track 14. Due to the presence of the mounting rod, the channel 15 can form a closed loop.

[0027] The tool module 8 includes a slider 16, an upper mounting plate 17, a lower mounting plate 18, a clamping roller 19, a tool 20, a foldable support rod 21 and a buckle 22. The slider 16 is slidably arranged between the first track 13 and the second track 14. The outer end of the lower mounting plate 18 is fixedly connected to the top surface of the slider 16. The foldable support rod 21 is arranged between the outer side of the top surface of the lower mounting plate 18 and the outer side of the bottom surface of the upper mounting plate 17. The clamping roller 19 is rotatably arranged between the top surface of the lower mounting plate 18 and the bottom surface of the upper mounting plate 17. The tool 20 is arranged on the top surface of the lower mounting plate 18 and the bottom surface of the upper mounting plate 17, and is located on the outside of the clamping roller 19. The foldable support rod 21 includes a lower rod 23, an upper rod 24 and a pin 25. The lower rod 23 The top end and the bottom end of the upper rod 24 are both provided with notches 26 that fit into each other, and the top end of the lower rod 23 and the bottom end of the upper rod 24 are connected at the notch by means of a pin 25, and the buckle 22 is provided on the upper rod 23 and the lower rod 24, and the setting of the notch 26 cooperates with the buckle 22 to achieve the purpose of limiting. In this way, the upper rod 23 can be opened toward the outside of the lower rod 24, and after the notch 26 is engaged, the upper rod 23 and the lower rod 24 are limited, ensuring that the clamping roller 19 can be clamped on the inner and outer sides of the wheel cover, and the tool 20 achieves the purpose of bilateral trimming of the edge of the wheel cover. The setting of the clamping roller 19 avoids the uneven trimming caused by the shaking of the wheel cover caused by the direct trimming of the tool 20, and when the edge of the wheel cover is tilted, the tool module 8 can be clamped on the inner and outer sides of the wheel cover, which is easy to install.

[0028] The transmission rod 10 includes a first transmission rod 27, a telescopic rod 28, a mounting seat 29, a ball 30 and a connecting rod 31.

When the tool module 8 slides, the transmission rod 10 used for transmission needs to meet the needs of the contour of the wheel cover. The transmission rod 10 utilizes the hinge of the first transmission rod 27 and the telescopic rod 28 to transmit rotational power. At the same time, the telescopic rod 28 changes, the ball 30 realizes universal transmission, and the telescopic rod 28 can be extended and retracted. When transmitting power, the requirements of the special-shaped track 7 are met.

[0029] The clamping structure 4 includes a clamping roller 32, a retractable pull rod 33, a pressing block 34 and a clamping motor. The clamping motor is arranged at the center of the workbench 1.

The clamping roller 32 is rotatably arranged at the ends of the two retractable pull rods 33. The cross-section of the pressing block 34 is a right triangle and is arranged on the side of the retractable pull rod 44. Driven by the clamping motor, the retractable pull rod 33 rotates to achieve the purpose of pressing the wheel cover.

[0030] Working principle:

[0031] Two workers and two wheel cover conveying lines and an output line are arranged on both sides of the workbench 1. When the wheel cover is transmitted on the wheel cover conveying line, the worker installs the wheel cover on the adsorption part 11, and the clamping motor drives the retractable pull rod 33 to rotate, and presses the wheel cover tightly when passing through the adsorption part 11.

[0032] After completing the pressing, the worker rotates the upper rod 24 and fastens the buckle 22. The clamping roller 19 clamps the wheel cover, and the tool 20 can trim both sides of the wheel cover. At this time, the motor 9 is turned on, and the transmission rod 10 drives the tool module 8 to rotate to achieve trimming. After the tool module 8 rotates one circle, the negative pressure device is closed, and the worker puts the wheel cover glass into the output line to complete the output of a wheel cover.

[0033] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
