Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ship plate welding devices, and more specifically, to a handheld ship plate welding device. Background Technology
[0002] Ship plate welding equipment is a key piece of equipment used in shipbuilding for welding hull steel plates, and its performance directly affects the safety and reliability of the ship structure. With the shipbuilding industry developing towards larger, more intelligent, and greener models, ship plate welding equipment is constantly innovating in technology to meet the demands for efficient, precise, and environmentally friendly welding. Handheld ship plate welding equipment is an important tool for on-site welding of hull steel plates in shipbuilding and repair, featuring flexibility and portability, and is suitable for welding ship plates of different sizes and shapes. Publication number CN220659537U discloses a handheld welding device, which includes a gun body and a laser emitter, beam splitter, half-wave plate, reflector, and focusing lens arranged sequentially along the optical path inside the gun body. The laser emitter emits a laser beam; the beam splitter splits the collimated laser beam into first P-polarized light and first S-polarized light; the half-wave plate converts the first S-polarized light into second P-polarized light; the reflector changes the propagation path of the first P-polarized light and the second P-polarized light so that the first P-polarized light and the second P-polarized light are incident on the focusing lens; the focusing lens converges the first P-polarized light and the second P-polarized light. The handheld welding torch of this application can convert a randomly polarized light beam into two p-polarized light beams. Using the welding equipment of this application for welding can improve the absorption rate of the workpiece to the light beam, thereby improving welding efficiency and effect.
[0003] However, existing technologies have some problems: existing handheld ship plate welding devices rely on workers holding handles to operate, but during long periods of welding work, workers will experience wrist fatigue, increasing their labor intensity. In addition, hand tremors may occur during the welding process, causing welding deviations and affecting the welding quality of the ship plates. Therefore, we propose a handheld ship plate welding device. Utility Model Content
[0004] One objective of this invention is to provide a new technical solution for a handheld ship plate welding device.
[0005] According to a first aspect of the present invention, a handheld ship plate welding device is provided, comprising a gun body, a handle fixedly connected to the gun body, a control switch provided on the handle, a bracket rotatably connected to the gun body, a wire feeding assembly provided on the bracket, a scale tube fixedly connected to the gun body, a copper nozzle fixedly connected to the scale tube, a support ring slidably connected to the scale tube, and a support assembly provided on the support ring.
[0006] Optionally, a connecting seat is fixedly connected to the gun body, a rotating shaft is fixedly connected to the connecting seat, and the bracket is rotatably connected to the rotating shaft.
[0007] Optionally, the rotating shaft has a groove, a spring is fixedly connected in the groove, a locking block is fixedly connected to the spring, and the bracket has a slot, with the locking block engaging in the slot.
[0008] Optionally, the wire feeding assembly includes a wire guide tube, which is fixedly connected to the bracket. One end of the wire guide tube is fixedly connected to a wire guide nozzle, and the other end of the wire guide tube is fixedly connected to a wire feeding hose.
[0009] Optionally, the scale tube has a slide rail, the support ring is slidably connected in the slide rail, the support ring has a threaded hole, and a fixing screw is threaded into the threaded hole to fix the support ring.
[0010] Optionally, the support assembly includes a rotating rod, which is fixedly connected to the support ring, and a support frame is rotatably connected to the rotating rod, the support frame being arc-shaped.
[0011] Optionally, the support frame is provided with a fixing groove, and a fixing knob is rotatably connected in the fixing groove. The fixing knob is threaded onto the rotating rod and is used to fix the support frame.
[0012] Optionally, a limiting groove is provided on the rotating rod, and a limiting block is fixedly connected to the support frame, with the limiting block rotatably connected within the limiting groove.
[0013] According to one embodiment of this disclosure, an adjustable bracket is provided, and multiple sets of grooves are formed on the rotating shaft. The multiple sets of grooves are evenly distributed on the rotating shaft in a circular pattern. Springs and locking blocks are correspondingly set in the grooves. When the operator holds the device to weld the ship plate, the ship plate may have other shapes such as curvature. The position of the wire guide tube and the wire guide nozzle can be adjusted by rotating the bracket to avoid the wire guide tube and the wire guide nozzle from contacting the ship plate and causing welding jamming or displacement, which would affect the welding quality.
[0014] This utility model is equipped with a support frame, which consists of two sets. When welding the ship plate, the support frame contacts the ship plate to support the welding device, reducing the shaking caused by manual handling during the welding process and ensuring accurate welding trajectory. At the same time, the mechanical support avoids prolonged manual holding, reducing labor intensity. In addition, a certain distance is left between the two sets of support frames to avoid obstructing the view during welding and affecting the welding quality.
[0015] When using the support frame, this utility model allows you to loosen the fixing knob, thus freeing the support frame from its grip. The support frame can then be rotated, causing the limiting block to rotate within the limiting groove. When the limiting block reaches one end of the limiting groove, it stops rotating. At this point, tightening the fixing knob secures the support frame. The limiting groove and limiting block ensure that the two sets of support frames remain horizontal, preventing misalignment and ensuring welding position deviation, which would affect welding quality. When not using the support frame, simply loosen the fixing knob, rotate the support frame twice to the graduated tube, and then tighten the fixing knob.

[0025] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the present invention.
[0026] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.
[0027] 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.
[0028] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0029] like Figure 1-6 As shown, a handheld ship plate welding device includes a gun body 1. Inside the gun body 1, a laser, collimating lens, and focusing lens are installed to generate a high-energy-density laser beam for welding. At the same time, a cooling system is usually installed inside the gun body 1 to dissipate heat from the device. The above-mentioned composition of the gun body 1 is a mature existing technology, which is believed to be well understood by those skilled in the art, and will not be described in detail here.
[0030] Furthermore, a handle 2 is fixedly connected to the gun body 1. The function of the handle 2 is to facilitate the staff to hold the device for long-term use. A control switch 3 is provided on the handle 2. The control switch 3 is used to control the output of the laser beam.
[0031] Furthermore, a bracket 4 is rotatably connected to the gun body 1, a connecting seat 10 is fixedly connected to the gun body 1, a rotating shaft 11 is fixedly connected to the connecting seat 10, and the bracket 4 is rotatably connected to the rotating shaft 11.
[0032] Furthermore, a groove is provided on the rotating shaft 11, a spring 12 is fixedly connected in the groove, a locking block 13 is fixedly connected on the spring 12, and a locking slot is provided on the bracket 4, with the locking block 13 locking into the locking slot.
[0033] Specifically, multiple sets of grooves are provided on the rotating shaft 11, and these grooves are evenly distributed around the circumference of the rotating shaft 11. The spring 12 and the locking block 13 are correspondingly set in the grooves. When the operator uses the handheld device to weld the ship plate, the ship plate may have other shapes such as curvature. The position of the wire guide tube 51 and the wire guide nozzle 52 can be adjusted by rotating the bracket 4 to avoid the wire guide tube 51 and the wire guide nozzle 52 from contacting the ship plate and causing welding jamming or displacement, which would affect the welding quality.
[0034] Specifically, when the bracket 4 rotates, the bracket 4 pushes the locking block 13 to compress the spring 12, causing the locking block 13 to disengage from the slot. When the next set of slots rotates to the locking block 13, the locking block 13 will re-engage in the slot due to the rebound force of the spring 12, thus fixing the bracket 4. The above process is repeated when the bracket 4 is rotated until the angle of the bracket 4 is adjusted and fixed at the current angle under the action of the spring 12 and the locking block 13.
[0035] Furthermore, a wire feeding assembly 5 is provided on the support 4. The wire feeding assembly 5 includes a wire guide tube 51, which is fixedly connected to the support 4. One end of the wire guide tube 51 is fixedly connected to a wire guide nozzle 52, and the other end of the wire guide tube 51 is fixedly connected to a wire feeding hose 53.
[0036] Specifically, the wire feeding hose 53 is connected to the wire feeding mechanism, which includes a motor and a wire feeding roller. The motor drives the wire feeding roller to rotate, thereby feeding the welding wire from the wire feeding hose 53 to the wire guide tube 51, and then feeding it out from the wire guide nozzle 52 for welding. The above-mentioned wire feeding process is a mature existing technology, and it is believed that those skilled in the art are already very familiar with it, so it will not be described in detail here.
[0037] Furthermore, a scale tube 6 is fixedly connected to the gun body 1, and a copper nozzle 7 is fixedly connected to the scale tube 6. The scale tube 6 serves as a support component for the welding gun, and its rigid design can reduce welding vibration and improve stability. The copper nozzle 7 concentrates the welding current at the end of the welding wire to form a stable arc and improve the welding energy density.
[0038] Furthermore, a support ring 8 is slidably connected to the scale tube 6. A slide rail is provided on the scale tube 6, and the support ring 8 is slidably connected in the slide rail. A threaded hole is provided on the support ring 8, and a fixing screw 14 is threadedly connected in the threaded hole. The fixing screw 14 is used to fix the support ring 8.
[0039] Specifically, after tightening the fixing screw 14, the support ring 8 can no longer slide in the slide of the scale tube 6. When it is necessary to adjust the position of the support component 9, the fixing screw 14 is loosened so that the support ring 8 can slide in the slide of the scale tube 6. At this time, the position of the support ring 8 is adjusted. After the adjustment is completed, the fixing screw 14 is tightened again to fix the support ring 8. By adjusting the position of the support component 9, the scale tube 6 and the copper nozzle 7 can be inserted into the gap for welding when welding the gap of the ship plate.
[0040] Furthermore, a support assembly 9 is provided on the support ring 8. The support assembly 9 includes a rotating rod 91, which is fixedly connected to the support ring 8. A support frame 92 is rotatably connected to the rotating rod 91, and the support frame 92 is arc-shaped.
[0041] Specifically, a fixing groove is provided on the support frame 92, and a fixing knob 93 is rotatably connected in the fixing groove. The fixing knob 93 is threadedly connected to the rotating rod 91 and is used to fix the support frame 92.
[0042] Furthermore, a limiting groove is provided on the rotating rod 91, and a limiting block 94 is fixedly connected to the support frame 92. The limiting block 94 is rotatably connected in the limiting groove.
[0043] Specifically, there are two sets of support frames 92. When welding the ship plate, the support frames 92 contact the ship plate to support the welding device, reducing the shaking when manually holding the device during the welding process and ensuring accurate welding trajectory. At the same time, the mechanical support avoids prolonged manual holding, reducing labor intensity. In addition, a certain distance is left between the two sets of support frames 92 to avoid obstructing the view during welding and affecting the welding quality.
[0044] Specifically, when using the support frame 92, the fixing knob 93 can be loosened so that the fixing knob 93 is no longer fixing the support frame 92. At this time, the support frame 92 can be rotated. When the support frame 92 rotates, it will drive the limiting block 94 to rotate in the limiting groove. When the limiting block 94 rotates to one end of the limiting groove, it stops rotating. At this time, the fixing knob 93 is tightened to fix the support frame 92. The limiting groove and the limiting block 94 can ensure that the two sets of support frames 92 remain horizontal, avoid misalignment, and prevent welding position deviation, which would affect the welding quality.
[0045] The aforementioned handheld ship plate welding device is equipped with an adjustable bracket 4. Multiple sets of grooves are formed on the rotating shaft 11, and the multiple sets of grooves are evenly distributed in a circle on the rotating shaft 11. Springs 12 and locking blocks 13 are correspondingly set in the grooves. When the operator uses the handheld device to weld the ship plate, the ship plate may have other shapes such as curvature. The position of the wire guide tube 51 and the wire guide nozzle 52 can be adjusted by rotating the bracket 4 to avoid the wire guide tube 51 and the wire guide nozzle 52 contacting the ship plate, causing welding jamming or displacement, which would affect the welding quality.
[0046] This utility model is equipped with a support frame 92, and there are two sets of support frames 92. When welding the ship plate, the support frame 92 contacts the ship plate to support the welding device. During the welding process, it reduces the shaking when the hand is held manually, ensuring the accuracy of the welding trajectory. At the same time, the mechanical support avoids the need for the hand to hold the device for a long time, reducing labor intensity. In addition, a certain distance is left between the two sets of support frames 92 to avoid obstructing the view during welding and affecting the welding quality.
[0047] When using the support frame 92, the fixing knob 93 can be loosened, thus freeing the support frame 92 from its fixation. The support frame 92 can then be rotated, causing the limiting block 94 to rotate within the limiting groove. Rotation stops when the limiting block 94 reaches one end of the limiting groove. The fixing knob 93 is then tightened to secure the support frame 92. The limiting groove and limiting block 94 ensure that the two sets of support frames 92 remain horizontal, preventing misalignment that could lead to welding position deviations and affect welding quality. When not using the support frame 92, the fixing knob 93 is loosened, the support frame 92 is rotated twice to the scale tube 6, and then the fixing knob 93 is tightened again.
[0048] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
