Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a split-type handheld laser welding machine. Background Art

[0002] Existing laser welding machines often have excessively high internal temperatures during long hours of operation, which can damage the machine during the cutting process and cause losses.

[0003] The utility model, with publication number CN215316341U, proposes a split, handheld laser welding machine capable of rapid heat dissipation. The machine comprises a laser welding machine body and a water chiller disposed within the body. One side of the laser welding machine body has an open window, and a slide rail is provided on the inner floor of the laser welding machine body. A fixed slide frame is provided on the slide rail, and the water chiller is fixed to the fixed slide frame. A retractable door panel is hingedly connected to the bottom edge of the open window of the laser welding machine body. The inner wall of the retractable door panel is provided with a guide rail that cooperates with the slide rail. A limit stop is provided on the top of the inner wall of the retractable door panel. Rollers are provided on the bottom of the laser welding machine body and the top of the outer wall of the retractable door panel. This utility model has a simple structure, an ingenious and compact design, is convenient and safe to operate, and has excellent heat dissipation.

[0004] However, the above-mentioned prior art still has the following deficiencies when used: 1. The circulation pipeline on the chiller and the radiator in the body are usually fixedly connected. The movable setting of the chiller will affect the stability of the pipeline in the body and the reliable connection of the line. Simply put, the removable structure of the chiller will increase the complexity of the structure, thereby increasing the cost investment; 2. Ventilation holes are usually opened on the side wall of the box in the prior art, but the ventilation holes are in a normally open state. Therefore, when the welding machine is not in use, external moisture can easily enter the box through the ventilation holes, resulting in poor moisture-proof performance.

[0005] To this end, the utility model provides a split-type handheld laser welding machine. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a split handheld laser welding machine to solve the problems raised in the above background technology. The present invention has the advantage of increasing the heat dissipation space of the chiller without moving the chiller, greatly reducing the complexity of the structure, and thus reducing the cost investment. It also has the advantage of moisture-proof storage, delays line aging, and increases service life.

[0007] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solution: a split handheld laser welding machine, including a body and a chiller located in the body, heat dissipation windows are opened on both sides of the body, the bottom of the heat dissipation window is rotatably connected to a cover, and the top of the body is connected to a door frame by sliding up and down. After the cover closes the heat dissipation window, when the door frame drops to the extreme position, the outer wall of the cover and the opposite sides of the two vertical rods on the door frame are abutted.

[0008] Furthermore, two fan-shaped plates are welded on one side of the cover, one of which is close to both ends. The large end of the fan-shaped plate is arranged close to the free end of the cover, and the large ends of the two fan-shaped plates are welded with arc-shaped cover plates. The arc-shaped cover plates and the fan-shaped plates are provided with evenly distributed ventilation holes, and the outer arc wall of the arc-shaped cover plate is welded with a limit rod arranged away from the cover.

[0009] Furthermore, the inner peripheral walls of the heat dissipation windows are bonded with rubber strips that are sealed with the fan-shaped plates and the arc-shaped cover plates.

[0010] Furthermore, the limit rod and the arc-shaped cover plate are screwed together, a driving head is provided on the top of the limit rod, and a disassembly hole close to both sides and used in conjunction with the limit rod is opened on the top of the body, and a rubber seal is detachably connected in the disassembly hole.

[0011] Furthermore, a handle is welded to the outer side of the cover.

[0012] Furthermore, guide sleeves are welded on both sides of the heat dissipation window and are sleeved on the outside of the vertical rods, and a handle is welded on the top of the door frame.

[0013] Furthermore, a roller is provided on the inner side of the vertical rod, and a rubber sleeve is provided on the outer side of the roller.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. In the utility model, by arranging rotating covers on both sides of the machine body, the heat dissipation space of the chiller can be increased after the covers are opened, which greatly improves the heat dissipation efficiency of the chiller. Door frames are connected to the upper and lower sliding parts of the machine body, and the door frames are used to lock the closed covers. The covers can be easily opened by lifting the door frames upward. This arrangement makes the opening and closing operations of the covers more convenient. Compared with the existing technology, this method of improving heat dissipation efficiency has the advantages of simple structure and low cost.

[0016] 2. In the present invention, two fan-shaped plates are arranged on one side, and then an arc-shaped cover plate is welded to one end of the two fan-shaped plates. Ventilation holes are provided on the arc-shaped cover plate and the fan-shaped plate. Then, a limit rod for limiting the opening of the cover is provided on the outer arc wall of the arc-shaped cover plate. When the cover is opened, the heat dissipation space of the machine body is increased while preventing large-volume debris from entering the machine body.

[0017] 3. In the present invention, a rubber strip is provided in the heat dissipation window to seal with the fan-shaped plate and the arc-shaped cover plate. When the welding machine is not in use, the cover is closed. Under the action of the rubber strip, the entire inner cavity of the machine is in a closed state, which is convenient for moisture-proof storage. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 3 The utility model provides a technical solution: a split handheld laser welding machine, comprising a body 1 and a chiller 4 located inside the body 1. The function of the chiller 4 is to dissipate heat for the laser welding machine, which will generate a lot of heat during operation.

[0024] In this technical solution, heat dissipation windows 11 are provided on both sides of the body 1, and the chiller 4 is located between the heat dissipation windows 11 on both sides of the body 1. The bottom of the heat dissipation window 11 is rotatably connected to a cover 2, and the outer dimensions of the cover 2 are larger than the outer dimensions of the heat dissipation window 11. After the cover 2 is swung up, it can fit on the outer wall of the body 1 and block the heat dissipation window 11 at the same time. After the cover 2 is swung down, the two heat dissipation windows 11 are always open, and the heat dissipation space of the chiller 4 can be increased.

[0025] A portal frame 3 is connected to the top of the machine body 1, sliding up and down. In a specific implementation, preferably, guide sleeves 112 are welded to both sides of the heat dissipation window 11, which are mounted on the outside of the vertical rods 31. The guide sleeves 112 are welded to the outer wall of the machine body via cantilever arms. A handle 32 is welded to the top of the portal frame 3. After the cover 2 closes the heat dissipation window 11, when the portal frame 3 descends to its limit position, the outer wall of the cover 2 and the opposing sides of the two vertical rods 31 on the portal frame 3 abut against each other. In other words, the vertical rods 31 act as a limiter for the cover 2. When the portal frame 3 moves upward, driving the vertical rods 31 away from the cover 2, the cover 2 can be easily opened; conversely, the closed cover 2 can be easily locked. A handle 24 is welded to the outside of the cover 2, which is an operating component for manually operating the swinging of the cover 2.

[0026] Furthermore, one side of the cover 2 is welded with two fan-shaped plates 21, one of which is close to the two ends. The large end of the fan-shaped plate 21 is set close to the free end of the cover 2. The large ends of the two fan-shaped plates 21 are welded with an arc-shaped cover plate 22. One end of the arc-shaped cover plate 22 extends to the inner side of the cover 2. The arc-shaped cover plate 22 and the fan-shaped plate 21 are both provided with evenly distributed ventilation holes 23. The outer arc wall of the arc-shaped cover plate 22 is welded with a limit rod 221 set away from the cover 2. In other words, when the cover 2 is swung outward to a certain angle, it will be blocked by the limit rod 221. At this time, the arc-shaped cover plate 22 and the fan-shaped plate 21 use the ventilation holes 23 thereon to ventilate and dissipate heat for the chiller 4. The arrangement of the arc-shaped cover plate 22 and the fan-shaped plate 21 prevents large debris (such as branches, leaves, welding wire, welding rods, etc.) from entering the body 1, thereby avoiding damage to the components inside the body 1 and blocking the heat dissipation space around the chiller 4.

[0027] In this embodiment, the inner wall of the heat dissipation window 11 is bonded with a rubber strip 111 that is sealed with the fan-shaped plate 21 and the arc-shaped cover plate 22. This arrangement ensures that after the cover 2 is closed, the heat dissipation window 11 is in a sealed state. At this time, the entire inner cavity of the body 1 is isolated from the outside world, which has the advantage of being moisture-proof.

[0028] In this embodiment, the limit rod 221 and the arc-shaped cover plate 22 are screwed together, and a driving head 2211 is provided on the top of the limit rod 221. The top of the body 1 is provided with a disassembly hole 12 close to both sides and used in conjunction with the limit rod 221. A rubber seal 121 is detachably connected to the disassembly hole 12, and the rubber seal 121 and the disassembly hole 12 are plug-fitted. The driving head 2211 and the screwdriver are adapted to the structure. When it is necessary to fully open the cover 2 to inspect the chiller 4, it is only necessary to use a screwdriver to insert it into the disassembly hole 12, and then rotate the limit rod 221 to contact the limit. At this time, the maintenance personnel can inspect the chiller 4 through the heat dissipation window 11.

[0029] In this embodiment, a roller 311 is provided on the inner side of the vertical rod 31, and a rubber sleeve 3111 is provided on the outer side of the roller 311. When the vertical rod 31 moves up and down, the roller 311 rolls the cover 2, so that the cover 2 is rolled and blocked by the rubber sleeve 3111 to block the heat dissipation window 11. This arrangement greatly reduces the difficulty of docking the cover 2 and the vertical rod 31, and improves the convenience of the cover 2 in blocking the heat dissipation window 11.

[0030] Working Principle: To use the laser welding machine, manually grasp the handle 32 and lift it upward. The roller 311 on one side of the vertical rod 31 rolls up and away from the cover 2. Then, grasp the handle 24 and pull the cover 2 outward, revealing the curved cover plate 22 and the fan-shaped plate 21. This increases the ventilation space around the chiller 4, allowing the chiller 4 to dissipate heat efficiently. When storing the machine at a fixed location, manually push the cover 2 with the handle 24 to close the heat dissipation window 11. Then, press down on the door frame 3. The roller 311 moves downward and rolls the cover 2, causing it to fit tightly against both sides of the machine body 1. The internal cavity of the machine body 1 is now sealed and moisture-proof.

[0031] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
