Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, and particularly relates to a hemming tool with adjustable roller angle. Background Art

[0002] The robot hemming and pressing forming technology is a general assembly technology widely used in the manufacturing of automobile body doors and covers. The outer plate edge is bent by driving a hemming head by an industrial robot, and plastic deformation occurs to wrap the inner plate, so that the inner and outer plates are fixed. Among them, the hemming head is a key component, which mainly includes a main body, a floating head, a pressing wheel assembly, an elastic connection assembly and a flange. The main body is connected to the robot through the flange. The floating head movably penetrates through the bottom end of the main body. The pressing wheel assembly is installed at the bottom end of the floating head. The elastic connection assembly is arranged in the main body as a buffer mechanism of the pressing wheel assembly.

[0003] Most of the existing hemming heads are developed and designed for specific products, so that the pressing wheels in the pressing wheel assembly can only be limited to specific angles. When the hemming parts change, it is necessary to replace the pressing wheel assembly or switch the hemming head again, which is time-consuming and consumable, and the work efficiency is low. Although a small part of the hemming heads can realize the adjustment of the pressing wheel angle, their structural designs are complex and the manufacturing costs are relatively high. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a hemming tool with adjustable roller angle, which has a simple structural design, low manufacturing cost and adjustable roller angle.

Specific Embodiments

[0026] The present utility model will now be further described in conjunction with the accompanying drawings. These drawings are all simplified schematic views, which only illustrate the basic structure of the present utility model in a schematic manner, and therefore only show the components related to the present utility model.

[0027] Such as Figures 1 - 3As shown in the figure, a hemming tool with adjustable roller angle includes a main body 100, a connecting flange 200 installed at the top end of the main body 100, a floating head 300 whose top end extends into the main body 100 and is slidably matched with the main body 100, and a roller assembly 400 installed at the bottom end of the floating head 300. The roller assembly 400 includes a base 410, a mounting member 420, an adjustment group 430, and a roller 440. The top end of the base 410 is connected to the bottom end of the floating head 300. There are several mounting members 420, which are evenly arranged along the circumference of the bottom end of the base 410. The top end of the mounting member 420 is connected to the base 410 through the adjustment group 430. The roller 440 is installed at the bottom end of the mounting member 420. By connecting the base 410 and the mounting member 420 through the adjustment group 430, the mounting member 420 can rotate relative to the base 410, so that the angle of the roller 440 is adjustable. The structure design is simple and the manufacturing cost is low, which is especially suitable for applications in the stages of frequent replacement of hemming parts and hemming process tests. Specifically, the main body 100 is a prior art and will not be described in detail here; the roller 440 is a flat roller, a taper roller, and a thumb wheel.

[0028] As Figures 2 - 4 shown in the figure, the base 410 includes a main block 411 and a sub-block 412. The top end of the main block 411 is connected to the bottom end of the floating head 300. There are several sub-blocks 412, which are evenly arranged along the circumference of the bottom end of the main block 411 and are connected to the main block 411. The end of the sub-block 412 away from the main block 411 is connected to the top end of the mounting member 420 through the adjustment group 430. By setting the mounting member 420 at the end of the sub-block 412 away from the main block 411, a certain distance is provided between the rollers 440, which ensures enough space for the angle adjustment of each roller 440 and avoids interference between the rollers 440 during work. Specifically, the top end of the main block 411 is inserted into a radial groove opened in the middle of the bottom end of the floating head 300, and the connection between the main block 411 and the floating head 300 is realized by horizontally passing a bolt through the top end of the main block 411 and the bottom end of the floating head 300; the main block 411 and the sub-block 412 are integrally formed and connected; a calibration needle 600 is installed at the bottom end of the main block 411 for use during calibration; there are four sub-blocks 412, and one of the sub-blocks 412 is used as a reserved position for backup.

There are a plurality of mounting grooves 433, which are evenly arranged along the circumferential direction of the second shaft hole 421. The hinge pin 434 passes through the mounting hole 432, and the end thereof close to the mounting member 420 is inserted into the mounting groove 433. When adjusting the angle, the hinge pin 434 is removed, and then the mounting member 420 is manually rotated by a corresponding angle around the rotating shaft 431 according to the required angle, and finally the hinge pin 434 is reinstalled. The detachable connection between the split block 412 and the mounting member 420 is realized through the hinge pin 434, which is convenient for the subsequent replacement and maintenance of the roller 440. Specifically, a washer may be provided between the rotating shaft 431 and the second shaft hole 421; the hinge pin 434 is in threaded fit with the mounting groove 433; there are ten mounting holes 432 and twelve mounting grooves 433. Through the rotation angle difference during adjustment, an adjustable effect with a minimum of 6 degrees can be finally achieved, and the adjustable precision is relatively high; there are two hinge pins 434.

[0030] As Figure 2 , Figure 3 and Figure 6 shown, a card slot 4311 is opened at the bottom end of the end of the rotating shaft 431 away from the split block 412. A card 500 is installed on the side of the mounting member 420 away from the split block 412. The end of the card 500 close to the rotating shaft 431 extends into the card slot 4311. Through the cooperation setting of the card 500 and the card slot 4311, the abnormal movement of the rotating shaft 431 is prevented, thereby ensuring the stability of the mounting member 420 and thus ensuring the edge wrapping quality. Specifically, the card 500 is connected to the mounting member 420 by bolts.

[0031] As Figure 3 and Figure 4 shown, a 0-degree mark and an arrow direction are engraved on the side of the split block 412 away from the mounting member 420, which greatly facilitates the operator to adjust the angle.

[0032] As Figure 1 and Figure 2As shown in the figure, the hemming tool with adjustable roller angle further includes a display component 700. The display component 700 includes a scale ruler 710 and a pointer 720. The scale ruler 710 is installed on the plane side at the bottom end of the floating head 300.
