Description

Technical Field

[0001] This utility model relates to the technical field of laser welding, and in particular to a laser welding fixture. Background Technology

[0002] Laser welding technology, as a high-precision and high-efficiency advanced joining process, is applied in many high-end manufacturing fields such as automobile manufacturing, aerospace, electronic components, and medical devices. Compared with traditional welding methods, laser welding uses a high-energy-density laser beam as a heat source, which has significant advantages such as a small heat-affected zone, low deformation, large weld depth-to-width ratio, fast welding speed, and ease of automation.

[0003] In existing technologies, common protective solutions often adopt a separate design, such as independent protective masks or goggles. Although these devices can provide basic protection, they require operators to carry them separately and make manual adjustments to adapt to different welding working environments. However, in practical applications, the lack of direct linkage between the protective device and the welding tool makes it difficult to maintain a stable protective position during dynamic welding, which can easily affect the continuity and clarity of vision.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a laser welding fixture is proposed. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a laser welding fixture.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a laser welding fixture, comprising: a hand clamp, and a protective component sleeved on the outside of the hand clamp;

[0007] The handgrip pivot is provided with a rotatable connecting pivot, and the top of the pivot is provided with a threaded hole. The protective component includes: a first fixed frame and a second fixed frame, a welded filter disposed between the outer walls of the first fixed frame and the inner walls of the second fixed frame, and a connecting unit disposed between the first fixed frame and the second fixed frame.

[0008] The connecting unit is a mounting rod. The upper surfaces of the first fixing frame and the second fixing frame are provided with overlapping through holes. One end of the mounting rod passes through the through hole and is threadedly connected to the threaded hole.

[0009] In a preferred embodiment of this utility model, a rotating block is fixedly connected to the top of the mounting rod.

[0010] In a preferred embodiment of this utility model, a limiting block is fixedly connected to the top inner wall of the first fixed frame, and the limiting block is rotatably connected to the mounting rod.

[0011] In a preferred embodiment of this utility model, the limiting block is located between the first fixed frame and the rotating shaft.

[0012] In a preferred embodiment of this utility model, two symmetrical reinforcing rods are fixedly connected between the top of the first fixed frame and the top inner wall of the second fixed frame.

[0013] In a preferred embodiment of this invention, the opposite sides of the two reinforcing rods are slidably connected to the outer circumferential wall of the mounting rod.

[0014] In a preferred embodiment of this utility model, the end of each hand clamp has an arc surface.

[0015] In a preferred embodiment of this utility model, the welded filter is fixedly connected between the outer walls of the first fixed frame and the inner walls of the second fixed frame.

[0016] In a preferred embodiment of this utility model, the outer side of the handle of the hand clamp is covered with an anti-slip sleeve, which is made of heat-insulating and anti-slip material.

[0017] In a preferred embodiment of this utility model, an LED lighting lamp is provided on the lower edge of the second fixing frame.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] (1) This utility model provides a laser welding fixture. By setting up a protective component and a hand clamp, and by using a rotating shaft and a connecting unit to achieve detachable connection, it can achieve quick installation and angle adjustment, thereby simplifying the loading and unloading process of the protective device. This allows the operator to obtain stable eye protection during laser welding and effectively avoid strong light radiation damage. Compared with the common separate protective devices in the prior art, this fixture directly integrates the protective function into the hand tool, reducing the trouble of carrying and adjusting it, thereby improving the operating efficiency. Furthermore, it allows the protective position to be adjusted according to the welding task, enhancing the adaptability of the equipment and the user experience.

[0020] (2) This utility model provides a laser welding fixture. By setting symmetrical reinforcing rods between the first fixed frame and the second fixed frame, and fixing a limiting block on the inner wall of the top of the first fixed frame, the rigidity of the overall frame can be enhanced, preventing the components from deforming or loosening during dynamic use. The rotational connection between the limiting block and the mounting rod further ensures the range of motion of the hand clamp, reduces the risk of collision, ensures the stability of the fixture during welding operations, and guarantees welding accuracy.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] like Figure 1 As shown, a laser welding fixture includes: a hand clamp 1, and a protective component 3 sleeved on the outside of the hand clamp 1;

[0028] like Figures 1-3 As shown, the hand clamp 1 has a rotating shaft 4 for rotation connection at the pivot, and the top of the rotating shaft 4 has a threaded hole. The protective component 3 includes: a first fixing frame 301 and a second fixing frame 302, a welded filter 303 disposed between the outer wall of the first fixing frame 301 and the inner wall of the second fixing frame 302, and a connecting unit 5 disposed between the first fixing frame 301 and the second fixing frame 302.

[0029] The connecting unit 5 is: a mounting rod 501. The upper surfaces of the first fixing frame 301 and the second fixing frame 302 are both provided with overlapping through holes 306. One end of the mounting rod 501 passes through the through hole 306 and is threadedly connected to the threaded hole.

[0030] A rotating block 502 is fixedly connected to the top of the mounting rod 501. A limiting block 305 is fixedly connected to the inner top wall of the first fixing frame 301. The limiting block 305 is rotatably connected to the mounting rod 501 and is located between the first fixing frame 301 and the rotating shaft 4. Two symmetrical reinforcing rods 304 are fixedly connected between the top of the first fixing frame 301 and the inner top wall of the second fixing frame 302. The opposite side of the two reinforcing rods 304 is slidably connected to the outer circumference of the mounting rod 501. A welded filter 303 is fixedly connected between the outer walls of the first fixing frame 301 and the inner walls of the second fixing frame 302.

[0031] It should be noted that the combination of hand clamp 1 and protective component 3 allows the operator to obtain eye protection directly through the clamp during laser welding without having to carry additional separate equipment, thus simplifying the workflow.

[0032] The arrangement of the rotating shaft 4 and the connecting unit 5 allows the protective component 3 to be quickly installed and removed, and is securely fixed by a threaded connection, ensuring that it will not loosen during dynamic use. This not only reduces the risk of injury to the operator from strong light radiation, but also improves the efficiency of welding tasks, making the equipment more adaptable and improving the user experience.

[0033] After the mounting rod 501 passes through the through hole 306 of the first fixed frame 301 and the second fixed frame 302, it is connected to the threaded hole of the rotating shaft 4 to form an adjustable fulcrum. The rotational connection between the limiting block 305 and the mounting rod 501 further restricts the range of movement and prevents excessive rotation from causing a collision.

[0034] The reinforcing rods 304 are symmetrically arranged between the fixed frames to enhance the rigidity of the overall frame. Their sliding connection with the mounting rods 501 ensures that the frame remains stable during operation and reduces the possibility of deformation. The welded filter 303 is firmly fixed between the fixed frames to provide continuous and reliable protection.

[0035] like Figure 1 As shown, the outer side of the handle of the hand clamp 1 is covered with an anti-slip sleeve, which is made of heat-insulating and anti-slip material. An LED light is provided on the lower edge of the second fixing frame 302, and the clamp head of the hand clamp 1 is provided with an arc surface 2.

[0036] It should be noted that the hand clamp 1 with the arc surface 2 improves the contact area during clamping, enhances the operating comfort, and enables the fixture to maintain high precision and stability in complex welding environments. Additional functions such as anti-slip sleeve and LED lighting further optimize the operating experience, enabling the fixture to quickly adapt to different welding tasks in actual combat and reduce fatigue and errors.

[0037] When using this utility model, align the first fixing frame 301 and the second fixing frame 302 so that the through holes 306 on their upper surfaces overlap, then pass one end of the mounting rod 501 through the through hole 306 and screw it into the threaded hole of the rotating shaft 4 to achieve a threaded connection.

[0038] During this process, the limiting block 305 on the inner top wall of the first fixed frame 301 is movably connected to the mounting rod 501, which plays a stabilizing role and prevents excessive rotation. At the same time, two symmetrical reinforcing rods 304 are fixed between the first fixed frame 301 and the second fixed frame 302 and are slidably connected to the outer circumferential wall of the mounting rod 501 to enhance the overall rigidity.

[0039] When in use, the operator first holds the handle of the hand clamp 1, which is covered with a non-slip sleeve made of heat-insulating and non-slip material to provide a comfortable and safe grip. The workpiece is clamped by the arc surface 2 at the end of the hand clamp 1. This design increases the contact area and avoids damage to the workpiece surface.

[0040] During laser welding, the welding filter 303 of the protective component 3 automatically provides eye protection and blocks strong light radiation; the operator can adjust the angle of the mounting rod 501 by rotating the block 502, thereby changing the position of the protective component 3 so that it is always aligned with the welding point, ensuring a clear and safe field of vision.

[0041] The LED lights on the lower edge of the second fixed frame 302 can be turned on to provide auxiliary lighting in dark environments and improve operational accuracy.

[0042] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
