Description

Technical Field

[0001] This utility model relates to the field of electron beam welding technology, specifically to an electron gun with an adjustable angle. Background Technology

[0002] Electron beam welding refers to the welding process that uses an accelerated and focused electron beam to bombard the welding surface placed in a vacuum or non-vacuum, causing the workpiece to melt and achieve welding. Electron beam welding is widely used in many industries such as aerospace, nuclear energy, national defense and military industry, automobile and electrical instrumentation because it has the advantages of not requiring welding rods, being less prone to oxidation, having good process repeatability and small thermal deformation.

[0003] For example, CN220312064U discloses an electron gun with convenient angle adjustment, which is equipped with a fixed block and a connecting shaft. The structural design of the gun body and the connecting port allows the fixed block to rotate when the connecting shaft rotates on the support frame. The fixed block then drives the gun body to rotate inside the connecting port, thus facilitating angle adjustment. An installation mechanism is provided, with a connecting cover threaded to the left end of the installation rod, allowing two sets of installation rings to surround the outer wall of the gun body. The position of the installation strip is limited by the installation rod and the connecting cover, making it easy to install and disassemble. A connecting strip and a limiting rod are provided. The lower end of the limiting rod is engaged with the upper right end of the welding chamber, allowing the first sealing plate to be nested inside the connecting port. The position of the second sealing plate is limited by the connecting strip and the limiting rod, thus facilitating dust prevention when not in use.

[0004] However, the electron gun adjustment structure can only allow the electron gun to rotate around the connecting shaft within a certain range, but cannot deflect the electron gun. This limits the range of application of the electron gun during adjustment. Furthermore, during workpiece processing, the high welding temperature when the electron beam impacts the workpiece results in a large amount of metal vapor inside the equipment. When the metal vapor moves upward and enters the acceleration gap between the anode and the emitting cathode, it can easily cause high-voltage breakdown, leading to electron gun failure and thus reducing the stability of the electron gun during operation. Utility Model Content

[0005] The purpose of this invention is to provide an electron gun with a convenient angle adjustment, so as to solve the problems of limited operating range and metal vapor affecting the stability of the electron beam gun when adjusting the angle.

[0008] A protective assembly for filtering metal vapor is installed below the gun body. The protective assembly includes a protective shell. Inside the protective shell, there are several rectangular plates at the bottom. An activated carbon plate is placed above the rectangular plates. Several adsorption plates are fixedly connected to one side of the activated carbon plate. The adsorption plates have rectangular adsorption grooves inside.

[0009] Preferably, a fixed shaft is fixedly connected to both sides of the spherical seat, and a bearing is provided on the outside of the fixed shaft. Both the fixed shaft and the bearing are located inside the disc.

[0010] Preferably, a retaining ring is provided around the outer circumference of the disk, and the retaining ring is embedded in the inner wall of the equipment housing. The gear, the worm gear, and the first motor are all located inside the equipment housing.

[0011] Preferably, the guide rod has two guide rods symmetrically arranged on the upper and lower sides of the lead screw in the rectangular slider, and the rectangular slider is slidably connected on the guide rods.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention features a driving mechanism that allows the gun body to rotate horizontally around its own center and also to deflect around a spherical base. This allows for adjustment of the position and angle of the electron beam emitted by the gun body, improving the flexibility and range of electron beam adjustment during welding. Furthermore, the inclusion of a protective component isolates, blocks, and adsorbs the metal vapor generated during welding, reducing its movement into the gun body. This minimizes the risk of metal vapor entering the gun body and causing malfunctions, thus improving the stability of the welding process. Attached Figure Description

Support plates 46 are fixedly connected to both sides of the disc 42, providing support for the second motor 47, lead screw 48, and guide rod 410. A second motor 47 is located on one side above the support plate 46, facilitating rotation of the lead screw 48. The second motor 47 has a lead screw 48 fixedly connected to its output end. The lead screw 48 facilitates the movement of a rectangular slider 49. A rectangular slider 49 is externally connected to the lead screw 48, facilitating the movement of a boss 411. A guide rod 410 is internally connected to the rectangular slider 49, allowing for smooth movement of the slider 49 on the lead screw 48. A boss 411 is fixedly connected to one side of the center of the rectangular slider 49, facilitating the angle adjustment of the gun body 3. One end of the boss 411 is embedded inside the gun body 3. A protective assembly 5 for filtering metal vapor is located below the gun body 3. The protective assembly 5 includes... The protective shell 51 facilitates the housing and installation of the rectangular layer plate 52 and the activated carbon plate 53. Several rectangular layer plates 52 are located at the bottom inside the protective shell 51, which help isolate and block metal vapor generated during welding. Activated carbon plates 53 are located above the rectangular layer plates 52, which help adsorb upward-moving metal vapor particles. Several adsorption plates 54 are fixedly connected to one side of the activated carbon plates 53, which increases the adsorption area for metal vapor. Rectangular adsorption grooves 55 are formed inside the adsorption plates 54, which increases the contact area between the adsorption plates 54 and the metal vapor.

[0025] refer to Figure 2 , Figure 3 and Figure 4 As shown, fixed shafts 6 are fixedly connected to both sides of the spherical seat 41. The fixed shafts 6 facilitate the rotation of the spherical seat 41. Bearings 7 are provided on the outside of the fixed shafts 6 to reduce the rotational resistance and make the rotation of the fixed shafts 6 more stable. Both the fixed shafts 6 and the bearings 7 are located inside the disc 42. A retaining ring 8 is provided around the outside of the disc 42 to support it. Several ball bearings are embedded around the lower circumference of the retaining ring 8 to reduce its rotational resistance. The retaining ring 8 is embedded in the... Inside the inner wall of the equipment housing 1, the driven gear 43, the worm gear 44, and the first motor 45 are all located inside the equipment housing 1. Two guide rods 410 are provided and symmetrically arranged on the upper and lower sides of the lead screw 48 in the rectangular slider 49. By providing two guide rods 410, the stability of the rectangular slider 49 during movement can be improved. The rectangular slider 49 is slidably connected on the guide rods 410. The boss 411 has a T-shaped cross-section. A groove is provided inside the gun body 3 to accommodate the passage of the boss 411. The boss 411 is slidably connected inside the gun body 3.

[0026] refer to Figure 3 and Figure 5 As shown, the upper half of the protective shell 51 is trapezoidal, and the top of the protective shell 51 is fitted onto the outside of the gun body 3. The internal aperture of the rectangular layer plate 52 decreases from bottom to top inside the protective shell 51. By setting the rectangular layer plate 52 with trapezoidal internal aperture from bottom to top, it is easy to isolate and block the upward-moving metal vapor, reducing the movement of metal vapor particles into the internal area of ​​the activated carbon plate 53. The adsorption plate 54 is made of activated carbon. By setting the adsorption plate 54 made of activated carbon, it is easy to increase the adsorption effect of metal vapor. The rectangular adsorption groove 55 is opened around the inside of the adsorption plate 54. The internal aperture of the adsorption plate 54 decreases from bottom to top inside the activated carbon plate 53. By setting the adsorption plate 54 with trapezoidal internal aperture from bottom to top, it is easy to increase the contact area of ​​the adsorption plate 54 with metal vapor, thereby improving the adsorption effect of metal vapor.

[0027] Working principle: When the angle of the gun body 3 needs to be adjusted, the second motor 47 is started. The second motor 47 drives the lead screw 48 to rotate. When the lead screw 48 rotates, it drives the rectangular slider 49 and the boss 411 to move. When the boss 411 moves inside the gun body 3, it can drive the gun body 3 and the ball seat 41 to deflect along the fixed axis 6. When the first motor 45 is started, the first motor 45 drives the worm gear 44 and the driven gear 43 to rotate, which can drive the disc 42, the ball seat 41, and the gun body 3 to rotate in the horizontal direction, thereby adjusting the electron beam angle of the gun body 3. When the metal vapor generated during the welding process moves inside the equipment housing 1, the metal vapor moving towards the gun body 3 is first blocked by the rectangular plate 52. When the metal vapor that continues to move upward reaches the internal area of ​​the activated carbon plate 53, the activated carbon plate 53 and the adsorption plate 54 can adsorb the metal vapor particles, thereby reducing the transfer of metal vapor into the gun body 3 and maintaining the stability of the gun body 3 during processing and use.
