[0003] The welding heads on the surface of existing handheld laser cutting machines are usually in an exposed state. Therefore, when the handheld laser cutting machine is not in use, the welding heads on the surface of the handheld laser cutting machine in an idle state are very susceptible to impact or extrusion by foreign objects, causing deformation or damage to the welding heads. At the same time, the exposed welding heads are very susceptible to erosion or oxidation by dust, thereby affecting the precision and accuracy of the welding heads. To address this problem, we proposed a high-power laser cutting machine welding joint with self-protection function. Summary of the invention

[0010] Preferably, a sliding block is fixedly mounted on the surface of the support rod, and the sliding block is slidably connected to the surface of the protective frame, and when the sliding block moves, the support rod can move.

[0011] Preferably, a clamping hole is provided on the surface of the protective frame, and the clamping hole can limit the pop-up of the movable plate.

[0012] Preferably, the driven component includes: a rotating wheel, the surface of which is fixedly connected to one end of a spiral spring, the other end of which is fixedly mounted on the surface of a protective frame, a through hole being provided on the surface of the rotating wheel, and the cross bar can only re-enter the protective frame when the through hole on the surface of the rotating wheel is parallel to the limiting rod.

[0015] Compared with the prior art, the utility model provides a high-power laser cutting machine welding joint with a self-protection function, which has the following beneficial effects:

[0016] 1. The welding joint of the high-power laser cutting machine with self-protection function is provided with a control component, which moves a slider on the surface of the protective frame. The support rod fixed on the surface of the slider contacts the inner wall of the support block. When the support block is contacted, the connecting rod fixed on the surface of the support block can drive the movable plate to move under the support of the spring, and the protective tube fixed on the surface of the movable plate simultaneously moves laterally in the protective frame. After the lateral movement, the protective tube can wrap the welding head to protect the welding head to avoid deformation or damage of the welding head caused by accidental impact or extrusion during storage or idleness.

After the cross bar passes through, the through hole opened on the surface of the rotating wheel will resist the limit rod to be folded under the support of the torsion spring and moved out of the protective frame. After moving out, the limit rod bounces up under the support of the torsion spring and limits the bouncing of the moving plate through the limit block. This method can double limit the protective tube, achieve the purpose of double protection of the welding head, and avoid non-operating personnel accidentally touching the slider, causing the protective tube to bounce up, thereby causing damage to the welding head.

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a high-power laser cutting machine welding joint with a self-protection function, comprising a handheld laser cutting machine 1, a welding head 2 is arranged on the surface of the handheld laser cutting machine 1, a protective frame 3 is fixedly installed on the surface of the handheld laser cutting machine 1, a control component 4 and a driven component 5 are arranged in the protective frame 3, and the control component 4 includes: a protective tube 41, a movable plate 42, a spring 43, a connecting rod 44, a support block 45, a slide groove 46, and a protective member 47.

[0024] The protection tube 41 passes through the protection frame 3 and is slidably connected to the protection frame 3. A movable plate 42 is fixedly installed on the surface of the protection tube 41. The surface of the movable plate 42 is fixedly connected to one end of a spring 43. The other end of the spring 43 is fixedly installed on the inner wall of the protection frame 3. The surface of the connecting rod 44 is fixedly connected to the surface of the movable plate 42. A support block 45 is fixedly installed on the surface of the connecting rod 44. A slide groove 46 is provided on the surface of the support block 45. A protective member 47 for protecting the welding head 2 is provided in the protection frame 3. A slider 472 is moved on the surface of the protection frame 3. The support rod 471 fixed to the surface of the slider 472 contacts the inner wall of the support block 45. When the support block 45 is contacted, The connecting rod 44 fixed on the surface of the support block 45 moves synchronously, and the movable plate 42 fixed on the surface of the connecting rod 44 moves laterally under the support of the spring 43. When the movable plate 42 moves, the protective tube 41 fixed on the surface of the movable plate 42 can slide synchronously in the protective frame 3. When the protective tube 41 moves, it blocks the surface of the welding head 2. After blocking, the slider 472 is moved to the corner of the card hole 473. The shape of the card hole 473 is L-shaped. When the slider 472 moves to the corner, the pop-up of the movable plate 42 can be restricted. This method can avoid deformation or damage of the welding head 2 due to accidental impact, extrusion, etc. during storage or idleness.

[0025] The protective member 47 includes: a support rod 471, which passes through the protective frame 3 and is slidably connected to the protective frame 3, and the support rod 471 is slidably connected to the slide groove 46, so that the support rod 471 can move stably in the protective frame 3. A slider 472 is fixedly installed on the surface of the support rod 471, and the slider 472 is slidably connected to the surface of the protective frame 3. When the slider 472 moves, the support rod 471 can move. A clamping hole 473 is provided on the surface of the protective frame 3, and the clamping hole 473 can limit the pop-up of the movable plate 42. The driven component 5 includes: a rotating wheel 51, and the surface of the rotating wheel 51 is fixedly connected to one end of the spiral spring 53, and the other end of the spiral spring 53 is fixedly installed on the surface of the protective frame 3. A through hole 52 is provided on the surface of the rotating wheel 51. When the through hole 52 on the surface of the rotating wheel 51 is parallel to the limit rod 55, the cross bar 54 can re-enter the protective frame 3. A cross bar 54 is fixedly mounted on the surface of the movable plate 42, the surface of the cross bar 54 is hinged to a limit rod 55, the surface of the limit rod 55 is fixedly connected to one side of a torsion spring 56, the other side of the torsion spring 56 is fixedly mounted on the surface of the cross bar 54, a limit block 57 is fixedly mounted on the surface of the cross bar 54, and the limit rod 55 can be folded under the support of the torsion spring 56 when it is resisted. The shape of the clamping hole 473 is L-shaped, and the L-shaped clamping hole 473 can limit the movable plate 42 from bouncing up.

[0026] In the present invention, when it is used, when it is necessary to protect the welding head 2 on the surface of the handheld laser cutting machine 1, the slider 472 is moved on the surface of the protective frame 3, and the support rod 471 fixed on the surface of the slider 472 contacts the inner wall of the support block 45. When the support block 45 is contacted, the connecting rod 44 fixed on the surface of the support block 45 moves synchronously, and the moving plate 42 fixed on the surface of the connecting rod 44 is forced to move laterally under the support of the spring 43. When the moving plate 42 moves, the protective tube 41 fixed on the surface of the moving plate 42 can be in the protective frame 3, and synchronously move. The protective tube 41 is slidable, and the surface of the welding head 2 is shielded when the protective tube 41 moves. After shielding, the slider 472 is moved to the corner of the clamping hole 473. The clamping hole 473 is L-shaped. When the slider 472 moves to the corner, the pop-up of the movable plate 42 can be restricted. At the same time, when the movable plate 42 moves, the cross bar 54 fixed on the surface of the movable plate 42 will pass through the protective frame 3. After the cross bar 54 passes through, the through hole 52 opened on the surface of the rotating wheel 51 will resist the limit rod 55 and fold under the support of the torsion spring 56, and move out of the protective frame 3. After moving out, The limiting rod 55 pops up under the support of the torsion spring 56, and limits the popping up of the movable plate 42 through the limiting block 57. This method can double-limit the protective tube 41, so as to achieve the purpose of double protection of the welding head 2, and avoid non-operating personnel accidentally touching the slider 472, causing the protective tube 41 to pop up, thereby causing damage to the welding head 2. This method can prevent the welding head 2 from being deformed or damaged due to accidental impact, extrusion, etc. during storage or idleness, and at the same time prevent dust, debris, etc. from accumulating on the welding head 2, keeping it clean, so as not to affect the performance during subsequent use. The purpose of self-protection is achieved. When the welding head 2 needs to be used again, the wheel 51 is rotated on the surface of the protective frame 3, and the through hole 52 opened on the surface of the wheel 51 gradually overlaps and becomes parallel with the limit rod 55. After becoming parallel, the rotation force is guaranteed to be stationary. The slider 472 is moved on the surface of the protective frame 3, and the slider 472 moves out from the corner of the card hole 473. Then, the moving plate 42 loses its restriction and bounces up under the support of the spring 43. After bouncing up, the rotation force is released, and the wheel 51 can be reversed under the action of the spiral spring 53 and return to its initial state.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
