[0011] As a preferred embodiment of the present invention, the sealing mechanism includes a sealing plate disposed at the bottom edge of the working cylinder, and a sealing airbag disposed at the bottom of the sealing plate.

[0012] As a preferred embodiment of the present invention, the limiting mechanism includes a limiting ring fixedly connected to the top of the working cylinder, and a limiting airbag is provided at the bottom of the limiting ring.

[0015] Compared with the prior art, the present invention provides an electron beam welding device for seam welding of laser levels, which has the following advantages: 1. In the electron beam welding device used for seam welding of laser level, the movable block slides in the groove through the limiting plate and the toggle rod. At the same time, the limiting spring plays a role in buffering and stabilizing the limiting, ensuring that the limiting roller is always in close contact with the outer wall of the housing assembly, thus achieving effective limiting and fixing. In this way, the electron beam welding device can adapt to laser level housing assemblies of different sizes, improving the flexibility and versatility of welding. 2. In the electron beam welding device used for laser level seam welding, heat is absorbed by the partition and transferred to the outside of the heat conduction box, so that the temperature of the heat conduction box continues to rise. When it approaches the weld point of the outer shell assembly, it can preheat it and increase the initial temperature of the weld point, thereby ensuring the thermal uniformity and welding quality of the weld point during the electron beam welding process. 3. In the electron beam welding device used for laser level seam welding, the motor can drive the ring to rotate in a circular motion without dead angles, thereby driving the electron beam welding gun to revolve around the axis of the working cylinder, improving the welding accuracy and efficiency, enabling the weld to be heated evenly, reducing the generation of welding defects, and ensuring full coverage of the welding area through the circular rotation without dead angles, eliminating the need for frequent manual adjustment of the welding gun position, saving manpower and time costs; 4. In this electron beam welding device for laser level seam welding, a high-definition camera is installed above the electron beam welding gun to monitor the cleaning effect of the weld seam in real time, providing a clean working environment for subsequent electron beam welding. The high-definition camera can be connected to an external display device via a data cable or wireless signal, and the operator can clearly observe the cleaning status of the weld seam on the display device and make adjustments as needed. 5. This is used in the electron beam welding device for laser level seam welding. The brush bristles will rotate and clean the weld seam, effectively removing impurities or oxides remaining on the weld seam surface and improving the quality of subsequent welding. 6.

Furthermore, this process can effectively remove residual impurities or oxides from the weld surface, thereby improving the quality of subsequent welding. By monitoring the weld cleaning effect in real time, a clean working environment is provided for electron beam welding, improving the sealing performance and service life of the laser welding between the end cap and the cylindrical tube.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] A laser level is a precision measuring tool that uses a laser beam to determine horizontal or vertical baselines. It is widely used in construction, decoration, engineering surveying and other fields. It mainly consists of a shell and internal detection devices. Laser levels come in various shapes and designs to adapt to different usage scenarios and needs, including handheld cylindrical laser levels. Currently, the shell of cylindrical laser levels is mainly pre-connected by end caps and cylindrical tubes. It is currently mainly assembled by simple welding. However, since laser levels are high-precision instruments, simple welding will affect their sealing, service life and accuracy. Example

[0022] Reference Figures 1-7 An electron beam welding device for seam welding of laser levels is provided. A worktable 1 is set on the ground, and a conveyor belt 2 is set on the worktable 1. The conveyor belt 2 is driven by a drive motor to move, and the surface of the conveyor belt 2 is smooth. The conveyor belt 2 is used to transport the laser level housing assembly to be welded to a designated position, that is, below the working cylinder 6. A vacuum pump 12 is set on the working cylinder 6. The vacuum pump 12 can extract the air in the working cylinder 6 to create a vacuum environment inside the working cylinder 6, so as to reduce the influence of oxygen on the welding process and improve the welding quality.

[0023] Three sets of circumferentially distributed connecting rings 13 are rotatably connected to the inner wall of the working cylinder 6. Limiting plates 14 are rotatably connected to the connecting rings 13, and limiting rollers 15 are rotatably connected to the ends of the limiting plates 14. A sliding groove 17 is provided on the inner wall of the working cylinder 6. A toggle rod 16 is rotatably connected to the limiting plate 14. The other end of the toggle rod 16 is slidably connected to the sliding groove 17 through a movable block. The movable block is connected to the inner wall of the sliding groove 17 through a limiting spring 18. A rubber pad is provided on the limiting roller 15 for flexible contact with the laser level housing assembly to limit its position. Through the cooperation of the connecting rings 13, the limiting plate 14, and the limiting roller 15, the laser level housing assemblies of different sizes can be limited and fixed. When the laser level housing assembly is transported to the bottom of the working cylinder 6, the outer wall of the level housing will contact the rubber pad on the limiting roller 15 during the descent of the working cylinder 6. The flexible contact design of the rubber pad can protect the housing assembly from damage and provide a certain friction to keep the housing assembly stable. As the working cylinder 6 continues to descend, a sealing mechanism is installed at the bottom of the working cylinder 6. The sealing mechanism cooperates with the top surface of the conveyor belt 2. A limiting mechanism is installed at the top inside the working cylinder 6. When the sealing mechanism abuts against the top surface of the conveyor belt 2, the limiting mechanism fits against the top of the level, thus combining the working cylinder 6 and the conveyor belt 2 to form a closed cavity. During the movement of the working cylinder 6, the limiting roller 15 drives the movable block to slide in the slide groove 17 through the limiting plate 14 and the actuating rod 16. At the same time, the limiting spring 18 plays a role in buffering and stabilizing the limiting, ensuring that the limiting roller 15 is always in close contact with the outer wall of the housing assembly, achieving effective limiting and fixing. In this way, the electron beam welding device can adapt to laser level housing assemblies of different sizes, improving the flexibility and versatility of welding.

[0024] Reference Figure 4 To facilitate the adjustment of the height of the working cylinder 6, two sets of symmetrical support members 3 are fixedly connected to the side wall of the worktable 1. A lead screw 4 is rotatably connected to the support member 3. The lead screw 4 is driven to rotate by the drive motor. A connecting plate 5 is fixedly connected to the outer wall of the working cylinder 6. The connecting plate 5 is threaded to the lead screw 4 and fits against the outer wall of the support member 3. By rotating the lead screw 4, the connecting plate 5 and the working cylinder 6 fixedly connected to it can be driven to move up and down, so that the height of the working cylinder 6 can be flexibly adjusted according to actual needs. At the same time, the stable support of the support member 3 and the threaded connection between the connecting plate 5 and the lead screw 4 ensure the stability and reliability of the working cylinder 6 during the lifting process.

[0025] Reference Figure 5 , Figure 6 and Figure 7Inside the working cylinder 6, a revolving mechanism is provided to drive the electron beam welding gun 10 to revolve around the axis of the working cylinder 6. The revolving mechanism includes an annular frame 7 fixedly connected to the working cylinder 6, a circular ring 8 rotatably connected to the annular frame 7, and the electron beam welding gun 10 fixedly connected to the inner wall of one side of the circular ring 8. A telescopic component 19 is provided on the inner wall of the other side of the circular ring 8. A negative pressure component is provided at the output end of the telescopic component 19. The telescopic component 19 is an electric telescopic rod or a cylinder. A motor 9 is also provided on the annular frame 7, and the output end of the motor 9 extends to the annular frame. The ring 7 is equipped with a main gear 901, and the outer wall of the ring 8 is equipped with an auxiliary gear 801. The main gear 901 and the auxiliary gear 801 mesh with each other. The motor 9 can drive the ring 8 to rotate in a circle without dead angles, which in turn drives the electron beam welding gun 10 to revolve around the axis of the working cylinder 6, improving the welding accuracy and efficiency, enabling the weld to be heated evenly, reducing the generation of welding defects, and ensuring full coverage of the welding area through the rotation without dead angles. There is no need for frequent manual adjustment of the welding gun position, saving manpower and time costs.

[0026] Secondly, a telescopic negative pressure component is installed on the surrounding mechanism. The end of the negative pressure component is arc-shaped and forms a semi-closed cavity. When it is necessary to weld the end cap on the level and the cylindrical tube, the negative pressure component can be used to clean the weld around the perimeter. At the same time, a high-definition camera 11 is installed above the electron beam welding gun 10 to monitor the cleaning effect of the weld in real time, providing a clean working environment for subsequent electron beam welding. The high-definition camera 11 can be connected to an external display device via a data cable or wireless signal. The operator can clearly observe the cleaning status of the weld on the display device and make adjustments as needed.

[0027] To facilitate the cleaning of the weld seam, the aforementioned negative pressure assembly includes an arc-shaped plate 20, which is fixedly connected to the output end of the telescopic component 19. A negative pressure cylinder 26 is provided on the arc-shaped plate 20, and a negative pressure rod 27 is slidably connected to the negative pressure cylinder 26. One end of the negative pressure rod 27 extends into the negative pressure cylinder 26 and is provided with a piston 29. The piston 29 is made of rubber and is connected to the inner wall of the negative pressure cylinder 26 by a spring. The other end of the negative pressure rod 27 is provided with a connecting clamp, and a contact wheel 28 is rotatably connected to the connecting clamp. An air inlet pipe 33 and an air outlet pipe 34 are respectively provided on the negative pressure cylinder 26. The air inlet pipe 33 faces the axis of the cleaning component, and a one-way control valve is provided on the air inlet pipe 33 and the air outlet pipe 34.

[0028] Of course, in other embodiments, when the telescopic member 19 drives the arc plate 20 to reciprocate, the contact wheel 28 at the end of the negative pressure rod 27 will always be in close contact with the outer wall of the outer shell assembly. At this time, the motor 9 is started, causing it to drive the ring 8 to rotate circumferentially. Furthermore, the ring 8 will rotate counterclockwise once and then clockwise once, rotating in a cyclical manner. This can prevent the coil from winding. At the same time, when the negative pressure rod 27 drives the piston 29 to reciprocate against the inner wall of the negative pressure cylinder 26, it will compress the gas in the negative pressure cylinder 26. Simultaneously, the piston 29 will generate heat through friction with the negative pressure cylinder 26. And when the telescopic member 19 drives the arc plate 20 to move closer to the outer shell assembly, the piston 29 will pressurize the gas in the negative pressure cylinder 26, making it... The internal gas is transported to the heat pipe 30 through the exhaust pipe 34. The heat pipe 30 is made of copper, which has good thermal conductivity. When the gas enters the heat pipe 30 through the exhaust pipe 34, the heat pipe 30 will transport the gas through the pipe to the heat box 31 made of silver or copper. The heat box 31 is provided with three sets of staggered baffles 32. The baffles 32 form airflow channels, which allows the baffles 32 to absorb heat and transfer it to the outside of the heat box 31, so that the temperature of the heat box 31 continues to rise. When it is close to the weld point of the outer shell assembly, it can be preheated to increase the initial temperature of the weld point, thereby ensuring the thermal uniformity and welding quality of the weld point during the welding process of the electron beam welding gun 10.

[0029] Secondly, when the telescopic component 19 moves the arc-shaped plate 20 away from the outer casing assembly, the spring inside the negative pressure cylinder 26 will eject the negative pressure rod 27, causing its contact wheel 28 to press tightly against the outer casing assembly. A negative pressure will be generated in the cavity of the negative pressure cylinder 26, which will in turn cause the air intake pipe 33 to generate a negative pressure suction force, thereby replenishing the air in the cavity of the negative pressure cylinder 26. A rotating shaft 21 is rotatably connected at the middle position of the arc-shaped plate 20. A connecting plate 22 is provided at one end of the rotating shaft 21, and bristles are provided on the connecting plate 22. 23. The heat-conducting boxes 31 are located on both sides of the rotating shaft 21, that is, the heat-conducting boxes 31 are fixedly connected to the arc-shaped plate 20. A heat-conducting pipe 30 is spirally wound on the negative pressure cylinder 26. One end of the heat-conducting pipe 30 is fixedly connected to the air outlet pipe 34, and the other end of the heat-conducting pipe 30 is connected to the cavity of the heat-conducting box 31. A transmission cavity 24 is opened inside the arc-shaped plate 20, and the heat-conducting box 31 is connected to the transmission cavity 24 through a pipe. The rotating shaft 21 extends into the transmission cavity 24 and is equipped with a vortex. When the piston 29 pressurizes the gas in the negative pressure cylinder 26, the gas inside is transported to the heat conduction pipe 30 through the exhaust pipe 34. The heat conduction pipe 30 then transports the gas to the transmission cavity 24, which in turn rotates the turbine blade 25, causing the brush bristles 23 on the connecting disc 22 to rotate. During this process, the brush bristles 23 rotate and clean the weld seam, effectively removing impurities or oxides from the weld surface and improving the quality of subsequent welding. At this time, due to the extension and retraction of the telescopic component 19, the negative pressure suction generated by the intake pipe 33 adsorbs some impurities and debris floating in the air of the working cylinder 6. The gas entering the transmission cavity 24 is then transported to the outside of the working cylinder 6 through a pipe. Alternatively, a telescopic pipe can be installed inside the working cylinder 6, with one end connected to the pipe and the other end placed outside the working cylinder 6, to extract some of the gas inside the working cylinder 6. It should be explained that the sealing mechanism includes a sealing plate 701 located at the bottom edge of the working cylinder 6, with a sealing airbag 702 at the bottom of the sealing plate 701. The limiting mechanism includes a limiting ring 703 fixedly connected to the top of the working cylinder 6, with a limiting airbag 704 at the bottom of the limiting ring 703. The limiting airbag 704 is connected to the sealing airbag 702 via a telescopic tube. When the sealing airbag 702 at the bottom of the working cylinder 6 comes into contact with the surface of the conveyor belt 2, gas will enter the limiting airbag 704 through the telescopic tube, causing the limiting airbag 704 to expand. This will then flexibly press the end cap on the cylindrical tube, ensuring a tighter connection between the end cap and the cylindrical tube. This effectively prevents the end cap from loosening or shifting due to gas impact or vibration during welding, thereby improving the stability and accuracy of welding. This design not only enhances the structural stability of the welding device but also greatly improves welding efficiency and weld quality. Meanwhile, through the synergistic effect of the sealing airbag 702 and the vacuum pump 12, the vacuum pump 12 is used to evacuate the working cylinder 6, thereby achieving effective sealing of the working cylinder 6, effectively isolating the interference of external air on the welding process, and further improving the welding quality.

[0030] Furthermore, when the electron beam welding gun 10 is engaged, the telescopic component 19 stops working, which will keep the bristles 23 away from the weld seam and prevent the bristles 23 from causing unnecessary interference or damage to the weld seam.

[0031] Components not described in detail in this article are existing technologies.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
