Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, specifically to a laser welding anti-deformation fixture for automotive parts. Background Technology

[0002] Laser welding of automotive parts is an advanced manufacturing technology that uses a high-energy-density laser beam as a heat source to achieve connection by focusing and melting the material. In order to maintain better stability of automotive parts during the welding process, the parts to be welded are usually fixed by a fixture to avoid welding failure caused by shaking during the welding process.

[0003] However, the clamping mechanism on existing laser welding fixtures for automotive parts is usually fixed in position on the fixture base. This means that the position of the clamping mechanism cannot be adjusted according to the size of the parts to be clamped, failing to meet the clamping requirements of parts of different sizes. This limits the scope of application of the fixture and makes it inconvenient for users to operate flexibly. In addition, existing welding fixtures usually suspend automotive parts on the fixture base, and the contact area between the parts and the clamping mechanism is small. This makes the automotive parts prone to sagging due to the large suspended area, which makes them more susceptible to deformation during the welding process. Utility Model Content

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 4As shown, the anti-deformation fixture for laser welding of automotive parts in this embodiment includes a base 1. The top of the base 1 has several insertion holes 3. Limiting holes 2 are provided at the four corners of the top of the insertion holes 3. The top of the insertion holes 3 is provided with a first card seat 4 and a second card seat 10 respectively. A first electric push rod 5 is installed on the top of the first card seat 4. A rotating plate 7 is provided on the top of the first electric push rod 5. A vertical column 11 is fixedly connected to the top of the second card seat 10. An upper clamping plate 15 is rotatably connected to the top of the vertical column 11. A lower clamping plate 16 is fixedly connected to the top of the front of the vertical column 11. A second electric push rod 13 is installed in the middle of the back of the vertical column 11 through an extended plate 12. Insertion posts 18 are fixedly connected to the middle of the bottom of the first card seat 4 and the second card seat 10. Limiting insertion rods 17 are fixedly connected to the four corners of the bottom of the first card seat 4 and the second card seat 10.

[0024] Specifically, the inner diameter of the insertion hole 3 is adapted to the outer diameter of the insertion post 18, allowing the first card holder 4 and the second card holder 10 to be inserted and fixed to the base 1 via the insertion post 18. A limiting rod 17 is inserted into the limiting hole 2, ensuring that the first card holder 4 and the second card holder 10 are stably inserted into the base 1. The first card holder 4 and the second card holder 10 serve as a connecting structure, allowing the positions of the clamping mechanism and the rotating plate 7, which provides additional support, to be adjusted and changed on the base 1. This improves the adaptability of the fixture and facilitates user operation. The first electric push rod 5 can lift the rotating plate 7 and the pads 9 on the rotating plate 7 to a suitable height, thereby enabling the clamping of automotive parts. The suspended and unclamped parts are supplemented with support to reduce the suspended area of ​​automotive parts during laser welding, thereby reducing the probability of sagging deformation of automotive parts due to large areas of suspension during the welding process. The vertical column 11 is the main support structure of this fixture, which can support the parts on the top of the base 1. The upper clamping plate 15 is a crank structure, and the lower clamping plate 16 is a detachable structure. The upper clamping plate 15 and the lower clamping plate 16 form the clamping mechanism on this fixture. The function of the second electric push rod 13 is to control the upper clamping plate 15, so that the upper clamping plate 15 can rotate along the top of the vertical column 11, thereby realizing the loosening or clamping of the automotive parts by the upper clamping plate 15 and the lower clamping plate 16.

[0025] Furthermore, a rubber ring 19 is fitted on the top of the insertion post 18, and the insertion post 18 is movably connected to the insertion hole 3 through the rubber ring 19. A sleeve 20 passes through the bottom end of the insertion hole 3, and the insertion post 18 and the sleeve 20 are movably inserted and connected. The function of the rubber ring 19 is to increase the friction coefficient between the insertion post 18 and the inner wall of the insertion hole 3, thereby enhancing the engagement degree between the insertion post 18 and the insertion hole 3. At the same time, the sleeve 20 can expand the contact area between the insertion hole 3 and the insertion post 18, making the connection between the insertion post 18 and the base 1 more stable.

[0026] Furthermore, the output end of the second electric push rod 13 is engaged with a connecting seat 14, which is rotatably connected to one end of the upper clamping plate 15. The upper clamping plate 15 is rotatably connected to the vertical column 11 through the connecting seat 14. The connecting seat 14 enables the end of the upper clamping plate 15 to be movably connected to the output end of the second electric push rod 13, so that the upper clamping plate 15 can grip or release the automotive parts.

[0027] Furthermore, the limiting rod 17 is movably connected to the limiting hole 2, and the first card seat 4 and the second card seat 10 are movably connected to the base 1 through the insertion post 18 and the limiting rod 17. The function of the limiting rod 17 is to prevent the cylindrical insertion post 18 from rotating in the insertion hole 3, thereby improving the stability of the connection between the first card seat 4 and the second card seat 10 and the base 1.

[0028] Furthermore, the output end of the first electric push rod 5 is fixedly connected to a connecting rod 6, and a locking screw 8 is movably inserted through one side of the top of the rotating plate 7. The function of the locking screw 8 is to lock the rotating plate 7 onto the connecting rod 6, so that the rotating plate 7 can ultimately maintain a stable state, so that the rotating plate 7 can provide supplementary support for the suspended part of the automotive component.

[0029] Furthermore, the bottom of the locking screw 8 is connected to the connecting rod 6 via a movable thread, and the rotating plate 7 is rotatably connected to the connecting rod 6 through the locking screw 8. The function of the rotating plate 7 is to allow the supported parts of the automotive components to be finely adjusted by rotating the rotating plate 7, thereby enhancing the supplementary support of the rotating plate 7 for the automotive components.

[0030] Furthermore, a pad 9 is provided on the other side of the top of the rotating plate 7, the bottom of the upper clamping plate 15, and the top of the lower clamping plate 16. The pads 9 are all wear-resistant silicone pads, which can fit the surface of the automotive parts well, and at the same time make the clamp less likely to damage the surface of the automotive parts, reducing the probability of deformation of the automotive parts during clamping.

[0031] The usage method of this embodiment is as follows: When using this automotive parts laser welding anti-deformation fixture, according to the size of the automotive parts to be clamped, the insert pin 18 on the second clamping seat 10 is inserted into the appropriate insertion hole 3 on the base 1. When the second clamping seat 10 is inserted into the insertion hole 3, the limiting insert rod 17 is also inserted into the corresponding limiting holes 2 around the insertion hole 3. At this time, the position of the vertical column 11 on the base 1 is fixed. Then, the remaining vertical columns 11 can be inserted into the corresponding positions. The automotive parts are then placed on the lower clamping plate 16 of the vertical column 11. Then, the second electric push rod 13 is activated to drive the upper clamping plate 15 to rotate along the top of the vertical column 11, so that the pad 9 at the bottom of the upper clamping plate 15 is clamped on the surface of the automotive parts. At this point, the automotive parts are simultaneously clamped onto the vertical column 11 by the upper clamping plate 15 and the lower clamping plate 16. Then, the first clamping seat 4 can be placed on the base 1 through the insert post 18, so that the first electric push rod 5 is located below the area where the automotive parts are suspended and not clamped. Then, the rotating plate 7 can be rotated, so that the rotating plate 7 drives the pad 9 on the top side to rotate to the appropriate orientation. Then, the locking screw 8 is tightened, so that the rotating plate 7 is stationary at the top of the connecting rod 6. Then, the first electric push rod 5 can be activated, so that the first electric push rod 5 pushes the rotating plate 7 and the pad 9 to the part where the automotive parts are suspended, providing additional support to the part where the automotive parts are suspended, so that the automotive parts are less likely to sag and deform during the subsequent laser welding process.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
