Description

Technical Field

[0001] This application relates to the field of laser welding technology for automotive parts, specifically to a laser welding clamping device for automotive parts that optimizes weld quality. Background Technology

[0002] Existing laser welding clamping devices are typically used to hold workpieces in place during laser welding to prevent displacement and ensure weld quality. However, for complex-shaped automotive parts, such as… Figure 1 As shown, the automotive parts include a base plate, a folding plate, and a connecting plate, and are long and narrow. Existing laser welding clamping devices are not effective at clamping automotive parts of specific shapes.

[0003] When welding such automotive parts, traditional clamping devices struggle to apply pressure accurately to critical areas, causing parts to shift during welding and affecting weld quality. For example, they cannot effectively secure the folding plate and base plate, leading to folding plate wobbling and base plate displacement during welding.

[0004] In addition, when clamping automotive parts with holes, the clamping of the holes may not be precise enough, making it difficult to adapt to the needs of holes of different sizes.

[0005] Therefore, it is necessary to provide a laser welding clamping device for automotive parts that optimizes weld quality to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] The purpose of this invention is to provide a laser welding clamping device for automotive parts that optimizes weld quality, in order to solve the problems mentioned in the background art.

[0008] The technical solution adopted by this application to solve its technical problem is:

[0009] A laser welding clamping device for automotive parts to optimize weld quality includes a processing table for clamping automotive parts. At least three mounting plates are installed on the processing table according to the shape of the automotive parts. Vertical plates are installed on the side walls of the mounting plates, and clamping components are rotatably mounted on the vertical plates.

[0010] The clamping assembly includes a first cylinder and a rotating frame. The first cylinder is hinged to the side wall of the vertical plate. The telescopic shaft of the first cylinder is hinged to one side of the rotating frame. A clamping part is provided on the top of the other side of the rotating frame. A first transverse clamping block is installed on the side wall of one end of the clamping part, and a second vertical clamping block is installed on the bottom surface of the other end of the clamping part.

[0011] A mounting base is installed on one side of the top surface of the vertical plate, a second transverse pressure block is installed on the side wall of the mounting base, and a first vertical pressure block is installed on the other side of the top surface of the vertical plate.

[0012] When the first cylinder drives the rotating frame to rotate on the vertical plate, the gap between the first and second transverse pressure blocks is used to press the automotive parts, and the gap between the first and second vertical pressure blocks is used to press the automotive parts.

[0013] Preferably, the bottom of the rotating frame is provided with a protrusion, and a buffer assembly is installed in the gap between the protrusion and the top surface of the vertical plate.

[0014] Preferably, the buffer assembly includes a fixing block, a first spring, a hydraulic rod, and a mounting block. The fixing block is connected to the top surface of the vertical plate, and the mounting block is connected to the bottom surface of the protrusion. The mounting block contains a hydraulic rod, and the first spring is sleeved on the hydraulic rod. The fixing block has a stepped hole inside, and the hydraulic rod abuts against the inside of the stepped hole.

[0015] Preferably, a hole clamping mechanism is installed on the side wall of the vertical plate located in the middle of the processing table. The hole clamping mechanism includes a second cylinder, a support plate, a sliding mechanism, two top plates, and a plug. The second cylinder is installed on the side wall of the vertical plate, and a movable seat is installed on the telescopic shaft of the second cylinder. The support plate is installed on the top surface of the movable seat. One side of the support plate is fixedly installed with the sliding mechanism. The two top plates are slidably installed on the support plate through the sliding mechanism. The plugs are all connected to the internal threads of the top plates.

[0016] Preferably, the sliding mechanism includes a slide rail and two slide blocks, the slide rail is connected to a support plate, the two slide blocks are slidably connected on the slide rail, and the top plate is mounted on the slide blocks.

[0017] Preferably, the side wall of the slide block is provided with a limiting mechanism, the limiting mechanism including a slide plate, a limiting head, a fixing rod and a second spring, the side wall of the slide rail is provided with a limiting groove, the fixing rod is installed on the side wall of the slide block, the slide plate is slidably installed on the fixing rod, the end of the fixing rod is provided with a limiting plate, the second spring is sleeved on the fixing rod and its two ends respectively abut against the side wall of the limiting plate and the slide plate, the limiting head is fixed to both ends of the slide plate, and the limiting head abuts against the limiting groove by the elastic force of the second spring.

[0018] The beneficial effects of this application are:

[0019] 1. This clamping device, by rotating and installing a clamping assembly on the vertical plate on the side wall of the mounting plate, can precisely clamp the middle and both ends of automotive parts. The first cylinder in the clamping assembly drives the rotating frame to rotate, using the gap between the first and second transverse clamping blocks to clamp the folded plate, and the gap between the first and second vertical clamping blocks to clamp the bottom plate. This solves the problem that traditional clamping devices cannot accurately apply pressure to the key parts of the parts, ensuring the stability of the automotive parts during the welding process, avoiding folded plate wobbling, bottom plate displacement, etc., and significantly improving the weld quality.

[0020] 2. This clamping device effectively solves the problems of inaccurate clamping of holes in automotive parts and difficulty in adapting to different hole sizes by using a hole clamping mechanism. The second cylinder can drive the support plate to move up and down to adjust the position of the top plate and the plug. The slide block in the sliding mechanism slides on the slide rail, which can adjust the distance between the two top plates to adapt to the holes of automotive parts of different sizes. At the same time, the limiting mechanism on the side wall of the slide block can ensure the accurate position of the slide block and avoid the position of the top plate and the plug from shifting, thus ensuring the accuracy of clamping the holes of automotive parts and further improving the welding quality.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0040] Please see Figure 1-7 The embodiments provided by this utility model are as follows:

[0041] like Figure 1 and Figure 2 As shown, a laser welding clamping device for automotive parts to optimize weld quality includes a processing table 7 for clamping automotive parts 1. At least three mounting plates 2 are mounted on the processing table 7 according to the shape of the automotive parts 1, such as... Figure 1 As shown, the automotive component 1 includes a base plate 11, a folding plate 13, and a connecting plate 12, and is in the shape of a long strip. Three mounting plates 2 are located on both sides of the middle section and both ends of the automotive component 1, respectively. Vertical plates 3 are installed on the side walls of the mounting plates 2. A clamping assembly 4 is rotatably mounted on the vertical plate 3, so as to clamp the middle section and both ends of the automotive component 1 through the clamping assembly 4 on the vertical plate 3, ensuring that the clamping assembly 4 can accurately apply pressure to the key parts of the automotive component 1, ensuring that the automotive component 1 is stable in position during the welding process, avoiding the impact of displacement on the welding quality, so that the laser welding device on the processing table 7 can perform welding processing on the automotive component 1. The laser welding device is a structure known to those skilled in the art, and will not be described in detail here.

[0042] like Figure 3 As shown, the clamping assembly 4 includes a first cylinder 41 and a rotating frame 42. The first cylinder 41 is hinged to the side wall of the vertical plate 3. The telescopic shaft of the first cylinder 41 is hinged to one side of the rotating frame 42. A clamping part 421 is provided on the top of the other side of the rotating frame 42. A first transverse pressure block 43 is installed on the side wall of one end of the clamping part 421. A second vertical pressure block 47 is installed on the bottom surface of the other end of the clamping part 421. When the telescopic shaft of the first cylinder 41 extends or retracts, it will drive the rotating frame 42 to rotate around the rotation point on the vertical plate 3, thereby realizing the clamping and loosening action.

[0043] A mounting base 44 is installed on one side of the top surface of the vertical plate 3, a second transverse pressure block 45 is installed on the side wall of the mounting base 44, and a first vertical pressure block 46 is installed on the other side of the top surface of the vertical plate 3.

[0044] When the first cylinder 41 drives the rotating frame 42 to rotate on the vertical plate 3, the gap between the first transverse pressure block 43 and the second transverse pressure block 45 is used to press the automotive component 1.

[0045] The gap between the first vertical pressure block 46 and the second vertical pressure block 47 is used to press the automotive component 1. Since the folding plate 13 and the base plate 11 of the automotive component 1 are arranged vertically, the gap between the first horizontal pressure block 43 and the second horizontal pressure block 45 is used to press the folding plate 13 of the automotive component 1. When the rotating frame 42 rotates, the gap between the first horizontal pressure block 43 and the second horizontal pressure block 45 will change to ensure that the folding plate 13 is fixed in position during the welding process and to prevent the folding plate 13 from shaking or deforming during welding. The gap between the first vertical pressure block 46 and the second vertical pressure block 47 is used to press the base plate 11 of the automotive component 1. Similarly, this ensures the stability of the base plate 11 during the welding process.

[0046] like Figure 4As shown, the bottom of the rotating frame 42 is provided with a protrusion 422. A buffer assembly 5 is installed in the gap between the protrusion 422 and the top surface of the vertical plate 3. The buffer assembly 5 includes a fixing block 51, a first spring 53, a hydraulic rod 54 and a mounting block 55. The fixing block 51 is connected to the top surface of the vertical plate 3, and the mounting block 55 is connected to the bottom surface of the protrusion 422. The hydraulic rod 54 is installed inside the mounting block 55. The first spring 53 is sleeved on the hydraulic rod 54. A stepped hole 52 is opened inside the fixing block 51, and the hydraulic rod 54 abuts against the inside of the stepped hole 52.

[0047] When the rotating frame 42 rotates and applies pressure to the automotive component 1, the protrusion 422 will squeeze the buffer assembly 5. The first spring 53 and the hydraulic rod 54 in the buffer assembly 5 will work together. The first spring 53 plays an initial buffering role, absorbing part of the impact force, while the hydraulic rod 54 further provides stable buffering force, effectively reducing the impact force of the rotating frame 42 on the vertical plate 3 and the automotive component 1, avoiding damage to the automotive component 1 or the device itself due to excessive impact force, and also making the pressing process smoother and improving the pressing effect.

[0048] like Figure 5 and Figure 6 As shown, a hole clamping mechanism 6 is installed on the side wall of the vertical plate 3 located in the middle of the processing table 7. The hole clamping mechanism 6 includes a second cylinder 61, a support plate 63, a sliding mechanism, two top plates 66, and a plug 67. The second cylinder 61 is installed on the side wall of the vertical plate 3. A movable seat 62 is installed on the telescopic shaft of the second cylinder 61. The support plate 63 is installed on the top surface of the movable seat 62. One side of the support plate 63 is fixedly installed with the sliding mechanism. The two top plates 66 are slidably installed on the support plate 63 through the sliding mechanism. The plug 67 is threadedly connected to the inside of the top plate 66.

[0049] When the telescopic shaft of the second cylinder 61 extends or retracts, it drives the support plate 63 to move up and down, thereby adjusting the position of the top plate 66 and the plug 67. The plug 67 is threadedly connected to the top plate 66. When the top plate 66 moves to the appropriate position, the plug 67 can press against the hole of the automotive part 1 to ensure that the hole will not shift during the welding process.

[0050] Specifically, such as Figure 6 As shown, the sliding mechanism includes a slide rail 64 and two slide blocks 65. The slide rail 64 is connected to the support plate 63, and the two slide blocks 65 are slidably connected on the slide rail 64. The top plate 66 is installed on the slide blocks 65. By sliding the slide blocks 65 on the slide rail 64, the distance between the two top plates 66 can be adjusted to accommodate the holes of different sizes of automotive parts 1.

[0051] Furthermore, such as Figure 7As shown, the side wall of the slide 65 is provided with a limiting mechanism, which includes a slide plate 651, a limiting head 654, a fixing rod 652, and a second spring 653. The side wall of the slide rail 64 is provided with a limiting groove 641. The fixing rod 652 is installed on the side wall of the slide 65. The slide plate 651 is slidably installed on the fixing rod 652. A limiting plate is installed at the end of the fixing rod 652. The second spring 653 is sleeved on the fixing rod 652 and its two ends abut against the limiting plate and the side wall of the slide plate 651, respectively. The limiting head 654 is fixed to both ends of the slide plate 651. The limiting head 654 abuts against the limiting groove 641 by the elastic force of the second spring 653.

[0052] The elastic force of the second spring 653 causes the limiting head 654 to abut against the limiting groove 641 on the side wall of the slide rail 64. When the slide 65 slides to a specific position on the slide rail 64, the limiting head 654 will engage with the limiting groove 641, thereby limiting the position of the slide 65. The limiting mechanism can ensure that the slide 65 is accurately positioned on the slide rail 64, preventing the top plate 66 and the plug 67 from shifting due to accidental sliding of the slide 65, and ensuring the accuracy of hole clamping.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
