[0034] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0035] In the present invention, unless otherwise clearly specified or limited, terms such as "installed", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Embodiment 1: Refer to Figures 1 - 3 , the present invention provides a technical solution: a handheld laser welding machine with adjustable welding density, including a grip 1, a switch 2 is fixedly connected to the outer surface of the grip 1, a laser welding machine 4 is fixedly connected to the top of the grip 1, a welding head 5 is rotatably connected to the inside of the laser welding machine 4, a vertical guiding mechanism 3 is fixedly connected to the outer surface of the laser welding machine 4, a guiding and balancing mechanism 6 is clamped to the outer surface of the welding head 5, and an adaptive locking mechanism 7 is clamped to the inside of the guiding and balancing mechanism 6. It further includes:

[0037] The vertical guiding mechanism 3 includes a through-groove column 301, the outer surface of the through-groove column 301 is fixedly connected to the outer surface of the laser welding machine 4, a slider 303 is slidably connected to the inside of the through-groove column 301, a metal elastic sheet 302 is fixedly connected to the outer surface of the slider 303, a groove-ring 304 is fixedly connected to the left end of the slider 303, a groove-slider 305 is clamped to the outer surface of the groove-ring 304, a horizontal laser instrument 306 is fixedly connected to the outer surface of the groove-slider 305, a first clamping block 307 is clamped to the outer surface of the groove-ring 304, a first rotating shaft connecting block 308 is fixedly connected to the outer surface of the first clamping block 307, a vertical laser instrument 309 is fixedly connected to the outer surface of the first rotating shaft connecting block 308, and a rotating wheel set 310 is rotatably connected to the outer surface of the first rotating shaft connecting block 308.

[0038] The right end of the metal elastic sheet 302 is fixedly connected to the outer surface of the laser welding machine 4, the first clamping block 307 is clamped with the slider 303, the first clamping block 307, the slider 303 and the notch height of the through-groove column 301 are the same, and the rotating wheel set 310 has four rotating wheels with different diameters vertically. By setting the vertical guiding mechanism 3, the vertical and horizontal display and auxiliary limiting functions are realized through the vertical laser instrument 309, the metal elastic sheet 302 and the rotating wheel set 310, and the welding head 5 can always be kept on the preset welding track through the metal elastic sheet 302 and the rotating wheel set 310, which can effectively avoid welding defects caused by position deviation and improve the quality and reliability of products.

[0039] The working principle of this embodiment is as follows: When using this handheld laser welding machine with adjustable welding density and performing welding by hand, at this time, the card slot slider 305 moves downward due to gravity and slides in the card slot of the card slot ring 304, making it perpendicular to the ground, and driving the horizontal laser instrument 306 to be perpendicular to the ground. While the welding head 5 is in contact with the welding surface, the metal elastic sheet 302 is pressed, causing the slider 303 to move inward, and moving inward through the first clamping block 307. Through the connection between the first clamping block 307 and the first rotating shaft connecting block 308, the rotating wheel group 310 is in contact with the welding seam or welding groove, and the first clamping block 307 enables the first rotating shaft connecting block 308 and the rotating wheel group 310 to rotate around the circle of the card slot ring 304. At this time, the rotating wheel group 310 realizes the clamping of welding seams with different widths and depths or the fitting of the surface of welding grooves with different widths and depths through multiple rotating wheels with different diameters. The vertical laser instrument 309 emits horizontal light. At this time, the first rotating shaft connecting block 308 and the rotating wheel group 310 rotate around the circle of the card slot ring 304 due to their own gravity and are flush with the horizontal light. At the same time, the vertical laser instrument 309 displays in the horizontal direction, and vertical auxiliary limiting is realized through the assistance of the rotating wheel group 310 and the horizontal laser instrument 306.

[0040] Embodiment 2: Please refer to Figures 4 - 6 , on the basis of Embodiment 1, the present invention provides a technical solution: The guiding and balancing mechanism 6 includes a first card slot 601, which is opened on the outer surface of the welding head 5. An arc-shaped clamping block 602 is clamped inside the first card slot 601. An annular card slot 603 is fixedly connected to the outer surface of the arc-shaped clamping block 602. A second clamping block 605 is clamped inside the annular card slot 603. A connecting frame 604 is fixedly connected to the top of the second clamping block 605. The connecting frame 604 is slidably connected to a sliding rod 606 through a through hole opened. A spring 607 is fixedly connected to the outer surface of the connecting frame 604. A first card sleeve 609 is fixedly connected to the top of the spring 607. A ball head hinge column 608 is clamped at the left end of the connecting frame 604. A third clamping block 610 is fixedly connected to the left end of the sliding rod 606. An arc-shaped card slot 611 is clamped on the outer surface of the third clamping block 610. A magnetic arc-shaped column 612 is clamped on the outer surface of the arc-shaped card slot 611 through a card slot opened.

[0041] The bottom of the ball head hinge column 608 is fixedly connected to the top of the first rotating shaft connection block 308. Third clamping blocks 610 are fixedly connected to both ends of the sliding rod 606. Two groups of welding heads 5 of the guiding and balancing mechanism 6 are symmetrically arranged on the outer surface. By setting the guiding and balancing mechanism 6, the precise positioning of the welding head 5 in the vertical direction is ensured through the coordinated action of the spring 607, the arc-shaped card slot 611, the magnetic arc-shaped column 612 and the vertical guiding mechanism 3, achieving an accurate welding position. And through the ball head hinge column 608, a stable structural system is formed in the vertical direction of the device, enhancing the resistance to vibration. Even in a working environment with large vibrations, the stable position of the welding head 5 can be maintained, ensuring that the welding quality is not affected.

[0042] The working principle of this embodiment is as follows: When using this handheld laser welding machine with adjustable welding density, while the first rotating shaft connection block 308 rotates circularly around the card slot ring 304, it pushes one end of the ball head hinge column 608 downward and the other end upward, and transfers the movement to the connecting frame 604 through the spherical groove. The torsion of the first rotating shaft connection block 308 is stopped by the ball head hinge column 608. At this time, driven by the ball head hinge column 608, the second clamping block 605 rotates in the annular card slot 603 through the connecting frame 604, and drives the sliding rod 606, the spring 607, the first clamping sleeve 609 and the third clamping block 610 to move upward and rotate around the axis of the sliding rod 606. When the metal elastic sheet 302 is pressed and the slider 303 moves inward, the main body of the guiding and balancing mechanism 6 is made to slide in the first card slot 601 through the arc-shaped clamping block 602 by the ball head hinge column 608. At this time, when the welding head 5 contacts the welding surface, the arc-shaped card slot 611 and the magnetic arc-shaped column 612 rotate around the axis of the sliding rod 606 due to gravity and remain perpendicular to the ground. The spring 607 pushes the arc-shaped card slot 611 and the magnetic arc-shaped column 612 perpendicular to the ground to contact the welding surface through the first clamping sleeve 609 and the third clamping block 610, and magnetic fixation is carried out through the magnetic arc-shaped column 612. At this time, it cooperates with another group of arc-shaped card slots 611 that move downward and are perpendicular to the ground, and limits the welding head 5 through the first clamping sleeve 609. By pulling by hand, the laser welding machine 4 moves up and down inside the arc-shaped card slot 611 through the third clamping block 610 to complete the vertical welding of the length of the arc-shaped card slot 611. If the next section of welding is required, then by hand, the arc-shaped card slot 611 and the magnetic arc-shaped column 612 are separated from the welding surface, and the above steps are repeated.

[0043] Embodiment Three: Please refer to Figures 7 - 8, on the basis of the first and second embodiments, the present invention provides a technical solution: the adaptive locking mechanism 7 includes a fourth block 701, the fourth block 701 is clamped with the annular slot 603, the outer surface of the fourth block 701 is clamped with a first base 702, the top of the first base 702 is fixedly connected with a first box body 703, the inner top of the first box body 703 is fixedly connected with an electromagnet 704, the top of the first base 702 is fixedly connected with a rubber elastic sheet 705, the top of the rubber elastic sheet 705 is fixedly connected with the bottom of the fourth block 701, the outer surface of the first base 702 is fixedly connected with a first connecting block 706, the outer surface of the first connecting block 706 is fixedly connected with a second box body 707, a hydraulic pump 708 is fixedly connected inside the second box body 707, the output end of the hydraulic pump 708 is fixedly connected with a circular block 709, the outer surface of the second box body 707 is fixedly connected with a second connecting block 710, and a horizontal laser 711 is fixedly connected inside the second connecting block 710.

[0044] The width of the first connecting block 706 is the same as the width of the annular slot 603, the diameter of the circular block 709 is the same as the diameter of the first slot 601, and a through hole with a diameter the same as that of the circular block 709 is opened at the bottom of the second box body 707. By setting the adaptive locking mechanism 7, in the horizontal direction, through the electromagnet 704 and the fourth block 701, the adaptive locking mechanism 7 can provide high-precision positioning support for the guiding and balancing mechanism 6, further enhancing the stability of the guiding and balancing mechanism 6; through the electromagnet 704, the rubber elastic sheet 705 and the hydraulic pump 708, firm locking and precise guiding are achieved, and its main body is suitable for auxiliary guiding in the horizontal direction.

[0045] Through the mutual cooperation of the above three mechanisms, dynamic balance adjustment is achieved through the spring 607 and precise guiding components are achieved through the arc-shaped slot 611, further optimizing the positioning accuracy in the vertical direction. Through the arc-shaped slot 611 and the third block 610, the small deviations caused by factors such as the self-weight of the equipment and operation vibration are effectively eliminated; the welding equipment with multi-mechanism collaborative work can achieve continuous and efficient welding operations, significantly shortening the production cycle and improving production capacity.

[0046] The working principle of this embodiment is as follows: When using this handheld laser welding machine with adjustable welding density, while the second block 605 rotates within the annular slot 603, if the magnetic arc-shaped column 612 is magnetically fixed to the welding surface, the electromagnet 704 pushes the fourth block 701 downward to move it into contact with the slot surface of the annular slot 603, causing the rotation of the second block 605 to stop and be fixed. When the welding head 5 contacts the welding surface, the hydraulic pump 708 pushes the circular block 709 to fix the movement of the arc-shaped block 602, fixing the position of the guiding and balancing mechanism 6. The adaptive locking mechanism 7 is clamped to the annular slot 603 through the fourth block 701 to achieve synchronous movement and is fixed through the symmetrically arranged adaptive locking mechanisms 7. After the position is fixed at this time, the horizontal light beam of the horizontal laser 711 and the horizontal light beam of the horizontal laser instrument 306 enable more accurate guiding when using the guiding and balancing mechanism 6.
