[0024] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0025] To improve welding efficiency and welding position accuracy, this utility model proposes a titanium shell welding system, such as... Figure 1 As shown, its structure includes: a sliding table fixture, which includes a sliding table body 3, a fixing part 6, and a dual-axis manual adjustment assembly. The fixing part 6 is disposed on the upper surface of the sliding table body 3 for receiving and fixing the titanium shell to be welded, and its shape is adapted to the shape of the titanium shell. The dual-axis manual adjustment assembly is partially embedded in the sliding table body 3; and a laser welding machine 1, which includes a flexible hose 2 that can be suspended at any position and is retractable. The end of the flexible hose 2 is provided with a laser welding head 8, which can be selectively moved closer to or further away from the sliding table body 3. The titanium shell welding system described in this application achieves continuous adjustment of the welding path in the X and Y axes by adjusting the dual-axis manual adjustment assembly to move the sliding table fixture. Thus, during the welding process, the sliding table body 3 can slide continuously, uniformly, and stably in the front-back, left-right, and right directions, solving the problem of not being able to move from point to line during welding and significantly improving the titanium shell welding efficiency.

[0026] In this embodiment, the titanium shell to be welded is first placed stably into the fixed part 6 of the slide table fixture, ensuring it remains in place without shaking. The retractable hose 2 of the laser welding machine 1 is adjusted so that the laser spot of the laser welding head 8 is precisely aligned with the starting point of the edge of the titanium shell to be welded on the slide table fixture. The slide table body 3 is adjusted to move smoothly along the Y-axis to complete the longitudinal weld. When the Y-axis moves to the end of the welding stroke or when the lateral position needs to be adjusted, the slide table body 3 is controlled to move laterally along the X-axis to gradually cover the lateral edge of the titanium shell. By alternately fine-tuning the X-axis and Y-axis movement directions, the slide table fixture drives the titanium shell to form a continuous motion trajectory in the two-dimensional plane, ensuring that the laser weld is seamlessly connected along the edge of the titanium shell, achieving a complete "point-to-line" welding. By adjusting the linkage between the slide table fixture and the laser welding machine 1 in the X-axis and Y-axis directions, this fixture upgrades traditional manual point welding to continuous linear welding, significantly improving the sealing performance and efficiency of the titanium shell.

[0027] In one embodiment, the titanium shell welding system further includes a mode switching module (not shown in the figure), which is mounted on the laser welding machine 1 and can serve as part of the control module of the laser welding machine 1. The mode switching module is used to switch between a manual adjustment mode and an electric control mode for moving the slide body 3. In manual adjustment mode, the operator can move the slide body 3 by adjusting the dual-axis manual adjustment assembly. In electric control mode, the movement of the slide fixture is driven by a transmission mechanism within the slide fixture via a servo motor mounted in the laser welding machine. During operation, the servo motor receives pulse signals from the control system (e.g., PLC or CNC system) and converts the electrical signals into precise rotary motion based on preset program parameters (speed, acceleration, and stroke). The torque is then transmitted to a transmission mechanism such as a ball screw or synchronous belt via a coupling, converting the rotary motion into linear displacement of the slide body 3.

[0028] This setup offers two flexible operating modes: manual adjustment and electric control. Operators can achieve precise movement of the slide table fixture through the dual-axis manual adjustment component, or select the electric control mode driven by the servo motor to obtain efficient and stable movement, thereby meeting different welding needs and improving operational convenience and welding quality.

[0029] In some embodiments, without the mode switching module, a dual-axis manual adjustment component can be directly set to move the slide fixture, thereby adjusting the area of ​​the welding area.

[0030] In one embodiment, the dual-axis manual adjustment assembly includes an X-axis knob 4 and a Y-axis knob 5 arranged perpendicularly to each other. The X-axis knob 4 is configured to adjust the lateral movement of the slide body 3 (e.g., ...). Figure 1 As shown), the Y-axis knob 5 is configured to adjust the longitudinal movement of the slide body 3 (as shown). Figure 1 As shown), the X-axis knob 4 or the Y-axis knob 5 is partially embedded within the slide body 3. Figure 1 In the illustrated embodiment, the X-axis knob 4 is partially embedded within the slide body 3. The X-axis knob 4 and the Y-axis knob 5 control the movement of the slide body 3 via mechanical transmission. When the X-axis knob 4 or the Y-axis knob 5 is rotated, the gear sets mechanically connected to the X-axis knob 4 and the Y-axis knob 5 respectively convert the knob angle change into direct mechanical displacement.

[0031] like Figure 1 As shown, the dual-axis manual adjustment assembly is equipped with an X-axis knob 4 and a Y-axis knob 5. The X-axis knob 4 and the Y-axis knob 5 are orthogonally distributed and can independently control the movement of the slide fixture in the X-axis and Y-axis directions. According to the actual welding requirements, flexible and precise manual adjustment can be performed, which significantly improves the convenience and positioning accuracy of welding operations.

[0032] The welding operation of the laser welding machine 1 is completed by stepping on a foot pedal (not shown in the figure), thereby realizing the start and stop of the welding process and the adjustment of welding parameters. The X-axis knob 4 and Y-axis knob 5 are adjusted by the operator's hands, improving welding flexibility and safety. Figure 3 As shown.

[0033] In one embodiment, the X-axis knob 4 includes an X-axis coarse adjustment knob and an X-axis fine adjustment knob, and the Y-axis knob 5 includes a Y-axis coarse adjustment knob and a Y-axis fine adjustment knob. The X-axis coarse adjustment knob and the X-axis fine adjustment knob are arranged adjacent to each other on one side of the slide body, and the Y-axis coarse adjustment knob and the Y-axis fine adjustment knob are arranged adjacent to each other on the other side of the slide body. These two sides are perpendicular to each other. The X-axis coarse adjustment knob, the Y-axis coarse adjustment knob, the X-axis fine adjustment knob, and the Y-axis fine adjustment knob are mechanically connected to the gear set. During use, to reduce accidental operation, the X-axis coarse adjustment knob and the X-axis fine adjustment knob can be arranged horizontally, and the Y-axis coarse adjustment knob and the Y-axis fine adjustment knob can be arranged vertically.

[0034] The X-axis knob 4 and Y-axis knob 5 are equipped with coarse and fine adjustment functions, respectively. In coarse adjustment, the gear ratio is reduced, and a single rotation of the knob corresponds to a larger displacement. When switching to fine adjustment, the gear ratio is increased, allowing even small changes in the knob's angle to correspond to micron-level displacement. The coarse adjustment knob enables rapid positioning of the slide fixture along the corresponding axis, while the fine adjustment knob provides micron-level adjustment accuracy. The combination of these two functions ensures both rapid alignment efficiency before welding and precise position control during welding, significantly improving the positioning accuracy and process adaptability of titanium shell welding.

[0035] In one embodiment, such as Figure 2 As shown, the fixing part 6 includes at least one fixing groove 7 disposed thereon. The fixing groove 7 can be in the form of a U-shaped groove, and its shape matches the surface shape of the titanium shell, thereby forming a full-circumferential wrapping contact, effectively dispersing the external load (such as vibration and impact) on the titanium shell, and avoiding deformation or damage caused by stress concentration. The U-shaped groove can also increase the effective contact area and increase the resistance experienced by the titanium shell.

[0036] In one embodiment, an elastic clamping module (not shown) for clamping the titanium shell can be provided on the inner wall of the fixing groove 7. The elastic clamping module includes a spring-loaded clamping block. The clamping block can adapt to different sizes of titanium shell outer diameter through the spring preload to achieve stable clamping, avoiding deformation or scratches of the titanium shell caused by rigid fixing. The elastic buffering characteristics of the spring can absorb welding vibration energy and reduce processing errors. The modular design facilitates quick replacement of the clamping block to adapt to irregularly shaped titanium shells, significantly improving clamping efficiency and welding yield.

[0037] In one embodiment, the inner side of the clamping block is provided with an arc-shaped guide surface. The curvature of the arc-shaped guide surface matches the outer diameter of the titanium shell. The clamping block can achieve precise guidance and stable clamping of the titanium shell through the curved surface fitting design, effectively reducing radial offset and axial movement during the clamping process, and reducing welding defects caused by positioning errors. The arc-shaped curved surface contact can disperse the clamping force, avoid deformation or surface damage of the titanium shell caused by excessive local pressure, and at the same time improve the universal adaptability of the clamping block to titanium shells of different specifications, simplify the clamping process and enhance process stability.

[0038] In one embodiment, optionally, a high-temperature resistant ceramic coating (not shown in the figure) is provided on the inner wall of the fixing groove 7, and a herringbone anti-slip pattern (not shown in the figure) is provided on the bottom of the fixing groove 7. The high-temperature resistant ceramic coating can effectively block the heat conduction of the welding high temperature to the slide table tooling, avoid deformation or cracking caused by thermal stress, and extend the service life of the tooling; the low coefficient of thermal expansion of the ceramic coating ensures the dimensional stability of the fixing groove 7 during the welding process. The herringbone anti-slip pattern on the bottom of the groove, through its intersecting oblique groove design, forms multi-directional frictional resistance when the titanium shell is fixed, effectively suppressing lateral slippage and circumferential rotation, and can also avoid groove deformation or titanium shell surface indentation caused by local stress concentration.

[0039] In one embodiment, the surface of the slide body 3 may be provided with multiple parallel or circumferentially uniformly distributed fixing parts 6, which can simultaneously fix multiple titanium shells and maintain a stable spacing, realize continuous welding operations, reduce workpiece clamping and positioning time, and improve welding efficiency; the uniformly distributed fixing parts 6 ensure the consistency of welding parameters of each shell, reduce quality fluctuations caused by position deviation, and improve tooling space utilization and equipment capacity.

[0040] It should be understood that, although Figure 2 The illustrated embodiment shows only one fixing part 6 and one fixing groove 7 disposed thereon. However, within the scope of this application, multiple fixing parts 6 and / or multiple fixing grooves 7 may be provided on the fixing part 6, all of which are within the scope of this application.

[0041] In one embodiment, the laser welding head 8 is equipped with a laser positioning indicator. The laser positioning indicator projects an annular positioning spot onto the edge of the titanium shell. The diameter of the spot matches the width of the edge of the titanium shell, thereby accurately marking the welding start position and path boundary through real-time visualization of the spot. This significantly improves the operator's positioning efficiency and accuracy of the titanium shell edge, and reduces welding misalignment or overlap caused by manual visual inspection. The size compatibility between the spot and the edge of the titanium shell can predict the welding coverage area in advance, optimize the matching degree of welding parameters, reduce rework rate and ensure the consistency of weld quality. At the same time, its non-contact indication method avoids physical contact damage to the surface of the titanium shell.

[0042] The physical application diagram of this utility model tooling is shown, along with the attached diagram.Figures 1-3 correspond.

[0043] X-axis knob 4 and Y-axis knob 5, with the left golden knob being the X-axis knob 4 and the right golden knob being the Y-axis knob 5. During operation, step on the foot switch of the laser welding machine 1 and rotate the X-axis knob 4 and Y-axis knob 5 in sequence by hand to move the slide body 3, thereby performing seamless welding.

[0044] The slide table fixture and its surface fixing part 6 and fixing groove 7 allow the titanium shell to be welded to be placed into the groove. Previously, only spot welding could be achieved, but now seamless welding can be achieved in all four directions.

[0045] Laser welding machine 1 and retractable hose 2 are used. During operation, the hose 2 of laser welding machine 1 is aligned with the edge to be welded.
