Description

Technical Field

[0001] This utility model belongs to the field of automotive door cover hemming, and specifically relates to an automotive door cover hemming device. Background Technology

[0002] With the increasing popularity of automobiles, the production volume of car door frames, as automotive parts, is also increasing year by year. Due to process reasons, door frame production requires edge rolling. During the production process of automobiles, various parts are processed and manufactured, including door covers and fenders. Since the processing quality of door covers and other components directly affects the aesthetics of the car, edge binding is required during the processing of door covers.

[0003] Chinese patent CN218517488U discloses an automotive sheet metal edging roller, comprising two support plates. The left support plate has a drive rod movably connected via a bearing to its left side, extending vertically through to its right side. The right support plate has a limit rod movably connected via a bearing to its left side. A rotating rod is movably connected between the limit rod and the drive rod, with both ends of the rotating rod penetrating and extending into the limit rod and the drive rod, respectively. A clearance hole is provided on the right side of the drive rod. This automotive sheet metal edging roller, with its cap-shaped design on the second roller, allows it to roll along the mold edge during operation, while the first roller pushes the edge. This interaction minimizes deviation and improves accuracy, resulting in a high yield rate. Simultaneously, a spring moves a fixed block, facilitating easy assembly and disassembly of the rotating rod.

[0004] As can be seen from the above structure, with the cap design of the first rolling wheel, during operation, the second rolling wheel rolls along the edge trajectory of the mold, and the first rolling wheel pushes the edge. The two interact with each other to prevent deviation and improve accuracy. However, as can be seen from the above figures and text, the edge-sealing device has poor flexibility and cannot flexibly adjust the distance between the rolling wheels. This results in an inability to effectively roll the edge of door covers of varying thicknesses. Furthermore, the angle adjustment is also poor, as the rolling angle of the door cover cannot be flexibly adjusted, thus reducing the practicality of the device. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an automotive door cover hemming device to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A car door cover hemming device includes a mounting plate. An adjusting assembly is fixedly connected to the upper end of the mounting plate. Connecting seats are slidably connected to both sides of the lower end of the mounting plate. Each connecting seat has a mounting groove at its lower end. A mounting plate is rotatably connected inside each mounting groove. A connecting rod is fixedly connected to the lower end of each mounting plate. A hemming wheel is provided at the other end of each connecting rod. The adjusting assembly includes adjusting plates on both sides of the upper end of the mounting plate. Adjusting screws are rotatably connected to the inner side of each adjusting plate. Adjusting threaded parts are threaded onto the outer surface of each adjusting screw. A bidirectional motor is fixedly connected to the upper end of the mounting plate. The output shaft of the bidirectional motor is fixedly connected to the adjusting screws.

[0008] Furthermore, as a preferred technical solution, the upper end of the mounting plate is provided with adjustment grooves on both sides, and adjustment sliders are slidably connected inside the adjustment grooves. Adjustment holes are provided inside the adjustment grooves. The upper end of the adjustment slider is fixedly connected to the adjustment threaded component, and the lower end of the adjustment slider is fixedly connected to the connecting seat. The connecting seat is slidably connected to the adjustment hole.

[0009] Furthermore, as a preferred technical solution, limit holes are provided on the inner side of the mounting groove, and limit screws are inserted into the inside of the limit holes. The limit screws pass through the mounting plate, and the other end of the limit screws passes through the mounting groove and is threadedly connected to a fixing nut.

[0010] Furthermore, as a preferred technical solution, the surface of the mounting plate is provided with limit holes, and multiple limit holes are provided, with the limit screws being inserted into the limit holes.

[0011] Furthermore, as a preferred technical solution, an angle pointer is fixedly connected to the lower end of each connector, and an angle comparison line is provided on the surface of each mounting plate. The angle pointer and the angle comparison line are used in conjunction with each other.

[0012] Furthermore, as a preferred technical solution, a spotlight is fixedly connected to the lower end of the mounting plate, and the spotlight is located directly above the plurality of rolling wheels.

[0013] Furthermore, as a preferred technical solution, a connecting column is fixedly connected to the upper end of the mounting plate, a fixing plate is fixedly connected to the upper end of the connecting column, a mounting rod is fixedly connected to the upper end of the fixing plate, and a flange is fixedly connected to the upper end of the mounting rod.

[0014] In summary, the present invention has the following main advantages:

[0015] Firstly, this automotive door cover hemming device, through its adjustable components, allows for adjustment of the distance between two hemming wheels. By controlling the rotation of a bidirectional motor, the adjusting screw rotates, causing the threaded adjusting threaded parts connected to it to move. This movement of the adjusting threaded parts on both sides drives the adjusting slider, which in turn moves the connecting seat, mounting plate, and hemming wheels. Ultimately, the angle between the hemming wheels can be adjusted through the adjustable components, making it more convenient and flexible to use.

[0016] Secondly, when adjusting the angle of the rollers in this car door cover roller edge device, firstly, the limiting screw inside the limiting hole is removed, allowing the mounting plate to move inside the mounting groove. Then, the mounting plate is rotated inside the mounting groove. The angle of the rollers can be observed by comparing the angle pointer with the angle alignment line. Once the angles of the rollers on both sides are aligned, the limiting screw is inserted through the limiting hole to connect with it. This allows the limiting screw to limit and fix the mounting plate. Finally, the limiting screw is fixed by connecting the fixing nut to the limiting screw. This allows for adjustment of the roller angle during use, thus increasing the practicality of the device. Attached Figure Description

The adjusting assembly 6 includes adjusting plates 61 located on both sides of the upper end of the mounting plate 1. Adjusting screws 62 are rotatably connected to the inner sides of each adjusting plate 61. Adjusting threaded parts 63 are threadedly connected to the outer surfaces of the adjusting screws 62. A bidirectional motor 64 is fixedly connected to the upper end of the mounting plate 1. The output shaft of the bidirectional motor 64 is fixedly connected to the adjusting screw 62. Adjusting grooves 12 are provided on both sides of the upper end of the mounting plate 1. Adjusting sliders 13 are slidably connected inside the adjusting grooves 12. Adjusting holes 14 are provided inside the adjusting grooves 12. The upper end of the adjusting slider 13 is fixedly connected to the adjusting threaded part 63. The lower end of the adjusting slider 13 is fixedly connected to the connecting seat 7. The connecting seat 7 is slidably connected to the adjusting hole 14. The threads of the two adjusting screws 62 are set in opposite directions, so that when the bidirectional motor 64 is controlled to rotate, the position of the adjusting threaded part 63 moves to the opposite position.

[0024] refer to Figure 3 and Figure 4 Each mounting groove 8 has a limiting hole 15 on its inner side. A limiting screw 16 is inserted into the limiting hole 15, and the limiting screw 16 passes through the mounting plate 9. The other end of the limiting screw 16 passes through the mounting groove 8 and is threadedly connected to a fixing nut 17. Multiple limiting holes 18 are provided on the surface of the mounting plate 9, and the limiting screw 16 is inserted into each limiting hole 18. By removing the limiting screw 16 inside the limiting hole 15, the mounting plate 9 can move inside the mounting groove 8. Then, the mounting plates are installed... The disc 9 rotates inside the mounting groove 8. When the angles of the rollers 11 on both sides are adjusted to be consistent, the limiting screw 16 is inserted into the limiting hole 18 through the limiting hole 15. Under the action of the limiting screw 16, the mounting disc 9 can be limited and fixed. Finally, the limiting screw 16 is fixed by connecting the fixing nut 17 to the limiting screw 16, so that the angle of the rollers 11 can be adjusted during use.

[0025] refer to Figure 3Angle pointers 19 are fixedly connected to the lower end of each connecting base 7, and angle comparison lines 20 are opened on the surface of each mounting plate 9. Angle pointers 19 and angle comparison lines 20 are used in conjunction with each other. The angle of the rolling wheel 11 can be observed by observing the angle pointers 19 and the angle comparison lines, and at the same time, the rolling wheel 11 can be adjusted to avoid deviation.

[0026] refer to Figure 3 A spotlight 21 is fixedly connected to the lower end of the mounting plate 1. The spotlight 21 is located directly above the multiple edge rolling wheels 11. The spotlight 21 allows for clear observation of the edge rolling condition of the door cover during use.

The flange 5 can be used to install the device, making it more convenient to install the equipment.

[0028] Operating Principle and Advantages: In use, the device can be installed first via the flange 5, facilitating easy installation. Then, multiple rollers 11 are used to roller the door cover of a car. When adjusting the distance between two rollers 11, the bidirectional motor 64 rotates, causing the adjusting screw 62 to rotate. This rotation moves the threaded adjusting threaded component 63, causing both sides of the threaded component 63 to move laterally. This movement of the adjusting threaded component 63 then moves the adjusting slider 13, which in turn moves the connecting seat 7, mounting plate 9, and rollers 11. Ultimately, the angle between the rollers 11 can be adjusted using the adjusting assembly 6. When it is necessary to adjust the angle of the rolling wheel 11, firstly, remove the limiting screw 16 inside the limiting hole 15 so that the mounting plate 9 can move inside the mounting groove 8. Then, rotate the mounting plate 9 inside the mounting groove 8. The angle of the rolling wheel 11 can be observed by observing the angle pointer 19 and the angle alignment line. When the angles of the rolling wheels 11 on both sides are adjusted to be consistent, the limiting screw 16 is inserted through the limiting hole 15 so that the limiting screw 16 is inserted into the limiting insertion hole 18. Under the action of the limiting screw 16, the mounting plate 9 can be limited and fixed. Finally, the limiting screw 16 is fixed by connecting the fixing nut 17 to the limiting screw 16. Thus, the angle of the rolling wheel 11 can be adjusted during use. The spotlight 21 can be used to clearly observe the rolling condition of the door cover during use.
