Description

Technical Field

[0001] The utility model belongs to the technical field of automobile door ring production, and particularly relates to a door ring positioning tooling with a protection function and capable of automatically removing slag.

Background Art

[0002] The automobile door ring is an important component of the vehicle. As shown in Figure (1), the automobile door ring 200 mainly includes an A-pillar 201, a B-pillar 202, and a reinforcing plate 203 at the upper ends of the A-pillar 201 and the B-pillar 202. During the production of the automobile door ring 200, a plurality of kidney-shaped holes 204 need to be laser-cut on the reinforcing plate 203. As shown in the cross-sectional view of Figure (8), the reinforcing plate 203 includes two mutually connected and angled first side plates 2031 and second side plates 2032. The first side plate 2031 is substantially horizontal, and the second side plate 2032 is substantially vertical. However, a bent connecting portion 2033 that extends obliquely upward from the first side plate 2031 to the top and then obliquely downward to the second side plate 2032 is formed at the connection position of the first side plate 2031 and the second side plate 2032. The bent connecting portion 2033 has an inverted "V" shape structure. A plurality of kidney-shaped holes 204 need to be laser-cut on the bent connecting portion 2033 close to the first side plate 2031 side. Since the cutting position is inclined, the other side opposite to the bent connecting portion 2033 and the second side plate 2032 will be burned during laser cutting. Designers have thought of setting a protective plate inside the bent connecting portion 2033 to protect the other side opposite to the bent connecting portion 2033 and the second side plate 2032 from being burned. However, during laser cutting, the cutting slag will accumulate on the protective plate. When the slag accumulates too high, it will damage the reinforcing plate 203, thereby affecting the cutting quality of the subsequent kidney-shaped holes 204. Since the space below the bent connecting portion 2033 is very narrow, it is difficult to use a conventional slag removal device to clean the protective plate. If manual cleaning is used, the cutting operation can only be carried out after the slag is cleaned up by shutting down the machine, which not only has a high labor intensity but also a low production efficiency.

[0003] Therefore, it is necessary to provide a door ring positioning tooling with a protection function and capable of automatically removing slag to solve the above technical problems.

Specific Embodiment

[0036] Please refer to Figures 1-8 , this embodiment is a door ring positioning tooling with a protection function and capable of automatically removing slag. The door ring positioning tooling 100 with a protection function and capable of automatically removing slag includes a mounting frame 1, a positioning mechanism 2 arranged above the mounting frame 1 for positioning the door ring 200, a support mechanism 3 for supporting the door ring 200 and arranged in a shape similar to the door ring, a pressing mechanism 4 for pressing the upper edge of the door ring 200, and a protection mechanism 5 arranged at the cutting position of the door ring 200 and having a protective effect on the door ring 200.

[0037] A number of quick installation holes 11 are provided on the mounting frame 1. The positioning tooling provided in this solution is inserted and positioned on the positioning posts on the machine table through the quick installation holes 11. When different-shaped door rings 200 need to be processed, the tooling can be directly removed to replace other positioning toolings. The insertion and positioning of the provided quick installation holes 11 make the replacement of the tooling simpler and more flexible.

[0038] The positioning mechanism 2 includes a first support frame 21 fixed on the mounting frame 1 and a positioning pin 22 arranged on the first support frame 21 and used to extend into the positioning hole of the door ring 200 to achieve positioning.

[0039] The support mechanism 3 includes a number of support components 31 supported on the lower side of the door ring 200. The shape and layout of the support components 31 are adapted to the structure of the door ring 200. The support components 31 support the lower surface, side edges, internal protrusions and depressions of the door ring 200. Its main function is to support the door ring 200 to make the door ring positioning stable and not deformed. The support component 31 includes a second support frame 311 fixed on the mounting frame 1 and a first contact part 312 fixed at the top of the second support frame 311 and in a shape similar to the lower surface of the door ring in contact. Since the door ring 2 has an irregular shape, the shape of the second support frame 311 can be designed into different structures according to the structure of the door ring 200, and can be designed into a vertical structure, a horizontal structure, an inclined structure or a curved structure, and cooperate with the first contact part 312 to enable the first contact part 312 to support various positions on the lower side of the door ring 200, so as to maintain the stability of the door ring 200 on the tooling. The shape of the second support frame 311 is adjusted according to the actual situation and is not limited here; the shape of the first contact part 312 is adapted to the structure of the lower surface of the door ring 200, and the first contact part 312 will not damage the structure of the door ring 200 when contacting and supporting the door ring 200. The first contact part 312 can be set as a spherical structure, a planar structure or an inclined surface structure, and is adjusted according to the actual situation and is not limited here.

[0040] There are several pressing mechanisms 4 located at the outer edge of the door ring 200. The pressing mechanism 4 and the support assembly 31 cooperate with each other vertically. The support assembly 31 supports the lower side of the door ring 200 from below, and the pressing mechanism 4 presses the upper side of the door ring 200 from above, clamping the door ring 200 relatively from top to bottom, making the positioning of the door ring stable and facilitating subsequent processing.

[0041] The pressing mechanism 4 includes a third support frame 41 fixed on the mounting frame 1, a first driving member 42 fixed on the third support frame 41, a rotating arm 43 driven by the first driving member 42 to rotate, a moving rod 44 fixed at the end of the rotating arm 43, and a pressing block 45 arranged on the moving rod 44 and used to press the upper side of the door ring 200. The moving rod 44 can be designed into different structures according to the actual layout. The lower end of the pressing block 45 is set as a hemispherical surface. When the pressing block 45 presses the upper side of the door ring 200, the hemispherical surface at the lower end of the pressing block 45 contacts the door ring 200 to avoid damaging the surface structure of the door ring 200. When the pressing block 45 presses the upper side of the door ring 200, the opposite lower side is supported by the support assembly 31.

[0042] The protection mechanism 5 is arranged on the mounting frame 1 and located at the position where the door ring 200 is laser cut. In this embodiment, multiple waist-shaped holes 204 need to be cut. Therefore, a protection mechanism 5 is arranged below each waist-shaped hole 204 to protect the opposite side of the bent connecting portion 2033 and the second side plate 2032 from being burned. The structures of the multiple protection mechanisms 5 are the same, and all extend into the space below the bent connecting portion 2033 to protect the opposite side of the bent connecting portion 2033 and the second side plate 2032.

[0043] The protection mechanism 5 includes a vertically arranged protection plate 51 for preventing the opposite side of the door ring 200 from being burned by the laser, a support module 53 for supporting and fixing the protection plate 51, and a slag shoveling component 52 arranged on the support module 53 and used to clean the slag on the protection plate 51.

[0044] A large amount of heat is generated during laser cutting. The protection plate 51 is made of copper with good thermal conductivity and fast heat dissipation. The protection plate 51 vertically extends into the lower side of the bent connecting portion 2033. When the laser cuts the waist-shaped hole 204 in the bent connecting portion 2033 on the side of the first side plate 2031, the protection plate 51 can protect the opposite side of the bent connecting portion 2033 and the second side plate 2032 from being burned. However, due to multiple cuts, the cutting slag will accumulate on the surface of the protection plate 51. When the slag accumulates too high, it will damage the reinforcing plate 203, thus affecting the cutting quality of the subsequent waist-shaped holes 204. Therefore, the slag shoveling component 52 is provided to remove the slag on the protection plate 51.

[0045] The slag shoveling assembly 52 includes a slag shovel 521 for shoveling the molten slag on the protection plate 51, a slag shovel support 522 for fixing the slag shovel 521, and a cylinder 523 for driving the slag shovel support 522 to drive the slag shovel 521 to move up and down.

[0046] The cutting edge of the slag shovel 521 faces the surface of the protection plate 51 to shovel the molten slag. The slag shovel 521 is fixedly installed on the slag shovel support 522 through a first gasket 524. On the one hand, the first gasket 524 can relieve the vibration and impact generated during the operation of the slag shovel 521, making the operation of the slag shovel 521 more stable; on the other hand, the distance between the cutting edge of the slag shovel 521 and the protection plate 51 can be finely adjusted by adjusting the thickness of the first gasket 524 to ensure the smoothness of the slag shoveling action.

[0047] The support module 53 includes a support body 531 for installing the protection plate 51 and the slag shoveling assembly 52, and an installation component 532 for installing the support body 531.

[0048] The cylinder 523 is fixed to the lower end of the support body 531, the protection plate 51 is fixed to the right side of the support body 531. An avoidance hole 5311 that penetrates the upper surface and is used to avoid the slag shovel support 522 is provided inside the support body 531. The avoidance hole 5311 is arranged in imitation of the lower end of the slag shovel support 522. The piston rod of the cylinder 523 and the position where the piston rod is connected to the lower end of the slag shovel support 522 are installed inside the support body 531, which can prevent the molten slag generated during laser cutting from splashing to the position of the piston rod, avoiding the splashed molten slag from affecting the extension and retraction actions of the cylinder 523, so that the slag shoveling assembly 52 cannot work; therefore, the piston rod of the cylinder 523 and the position where the piston rod is connected to the lower end of the slag shovel support 522 are installed inside the support body 531, which can ensure the normal operation of the residue assembly 52 and timely clean the molten slag on the protection plate 51.

[0049] The installation component 532 includes a first installation plate 5321 installed on the installation frame 1 and a second installation plate 5322 with one end installed on the first installation plate 5321 and the other end installed on the support body 531. The second installation plate 5322 has an "L" - shaped structure and the plate edges at both ends are perpendicular to each other. The first installation plate 5321, the second installation plate 5322, and the support body 531 are all installed and fixed by screws.

[0050] The bottom end of the first mounting plate 5321 is a horizontal plane and is mounted on the mounting frame 1 through the second gasket 5323. One end of the second mounting plate 5322 is mounted on the upper end of the first mounting plate 5321 through the third gasket 5324, and the other end is mounted on the support body 531 through the fourth gasket 5325. The second gasket 5323 is horizontally arranged, and the third gasket 5324 and the fourth gasket 5325 are both vertically arranged and perpendicular to each other. The height of the protective plate 51 and the slag shoveling assembly 52 in the Z direction can be finely adjusted by adjusting the thickness of the second gasket 5323, the position of the protective plate 51 and the slag shoveling assembly 52 in the X direction can be finely adjusted by adjusting the thickness of the third gasket 5324, and the position of the protective plate 51 and the slag shoveling assembly 52 in the Y direction can be finely adjusted by adjusting the thickness of the fourth gasket 5325. On the one hand, the provided gaskets can relieve the vibration and impact generated during the slag shoveling operation. On the other hand, the provided gaskets can be used to finely adjust the positions of the protective plate 51 and the slag shoveling assembly 52 in the three directions of X, Y, and Z, so that the protective plate 51 can adapt to the position of laser cutting, thereby well protecting the reinforcement plate 203.

[0051] On the positioning tooling, since there will be molten slag splashing during laser cutting, shielding covers are provided at all installation connection positions, screw installation connection positions, and positions with complex structures. On the one hand, it can prevent molten slag from splashing onto these positions and causing connection failure. On the other hand, the provided shielding covers are more convenient for cleaning molten slag.

[0052] When applying the door ring positioning tooling 100 provided with a protective function and capable of automatically clearing slag in this solution, the positioning tooling of this solution is inserted into the positioning machine table through the quick installation hole 11 on the mounting frame 1. The handling manipulator transports the door ring 200 to the positioning tooling. The positioning pin 22 extends into the positioning hole of the door ring 200 to realize the positioning of the door ring 200. Several support assemblies 31 support the lower side of the door ring. The first driving member 42 of the pressing mechanism 4 drives the rotating arm 43 to drive the moving rod 44 to rotate so that the pressing block 45 presses on the upper side edge of the door ring. At this time, the protective mechanism 5 is exactly below the bent connecting portion 2033. The protective plate 51 is vertically arranged and blocks the opposite side of the bent connecting portion 2033 and in front of the second side plate 2032. The positions of the protective plate 51 and the slag shoveling assembly 52 in the three directions of X, Y, and Z can be finely adjusted by adjusting the thickness of the gasket, so that the protective plate 51 can adapt to the position of laser cutting. Then, laser cutting starts. After cutting is completed, the cylinder 523 drives the cutter support 522 to extend upward to drive the cutter 521 to shovel the molten slag upward, and reciprocally extends and retracts to clean the molten slag on the protective plate 51.

[0053] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
