Description

Technical Field

[0001] The invention relates to the technical field of electron beam welding, in particular to an electron beam welding machine used for shell welding processing. Background Art

[0002] The working principle of an electron beam welder is that electrons are emitted from the cathode in the electron gun. These electrons are accelerated by a high-voltage electrostatic field and focused by an electromagnetic field to form an extremely high-energy electron beam. When the electron beam strikes the workpiece, its enormous kinetic energy is converted into heat, melting the workpiece at the weld point and forming a molten pool, thus achieving welding.

[0003] The welding machine is mainly composed of two parts: a turntable and an electron gun. During the welding process, the turntable rotates, but the gun body cannot move. This welding method requires high precision of the welding fixture, and the end face runout of the workpiece cannot exceed ±0.03mm. End face table detection is required before welding. If the tolerance range exceeds ±0.03mm, the electron beam cannot cover the weld runout width, resulting in welding defects. Under such circumstances, welding must be repeated with fixtures and measurements, resulting in reduced welding efficiency and increased welding costs.

[0027] In one embodiment of the present invention, see Figure 1-Figure 3 , an electron beam welding machine for shell welding processing, comprising an operating chamber 1 and a vacuum chamber 8, the operating chamber 1 and the vacuum chamber 8 being communicated, the vacuum chamber 8 being used to evacuate the operating chamber 1, a movable component 2 being movably provided inside the operating chamber 1, a movable component 3 being movably provided on the movable component 2, the movable component 3 being used to press the two hemispherical shells 9 to be welded and drive the two hemispherical shells 9 to rotate synchronously, a camera 4 and an angle detection component 5 being provided on the movable component 3, the camera 4 being used to photograph the connecting seam between the two hemispherical shells 9, the angle detection component 5 being used to detect the rotation angle of the two hemispherical shells 9, an opening being provided on one side of the operating chamber 1, a movable side plate 101 being movably provided at the opening, an adjustment component 7 being movably provided on the side of the operating chamber 1 away from the opening, and an electron gun 6 being provided on the adjustment component 7.

[0028] In this embodiment, the inner space of the operating chamber 1 is sealed by the cooperation of the operating chamber 1 and the movable side panel 101. The inner space of the operating chamber 1 can be evacuated by the vacuum chamber 8. The position and angle of the two hemispherical shells 9 can be adjusted by the cooperation of the movable component 2 and the movable component 3, which facilitates the placement and electron beam welding of the hemispherical shells 9. The fluctuation of the connection seam of the two hemispherical shells 9 can be detected in real time by the cooperation of the camera 4 and the angle detection component 5. The height of 6 can be adjusted in real time according to the fluctuation degree of the connection seam by 7, which facilitates the precision welding of the two hemispherical shells 9.

In the initial state, the movable side panel 101 cooperates with the opening of the operating room 1, and the internal space of the operating room 1 is in a closed state. The interior of the operating room 1 can be vacuumed to facilitate the subsequent welding of the hemispherical shell 9.

Through the cooperation of the movable component 2 and the movable component 3, the welded hemispherical shell 9 can be removed, which is convenient for the subsequent placement and welding operations of the hemispherical shell 9.

[0029] In one embodiment of the present invention, see Figure 1-Figure 4The moving assembly 2 includes a placement rack 214 arranged outside the opening of the operating room 1, a first rack 201 is installed on the inner wall of the placement rack 214, a guide rail 202 is symmetrically arranged on the inner wall of the operating room 1, a second rack 203 corresponding to the first rack 201 is provided on the guide rail 202, a movable plate 204 is movably provided in the operating room 1 and slides with the guide rail 202, the bottom of the movable plate 204 is symmetrical and rotatably provided with a support roller 213 that is in active contact with the placement rack 214, and mounting seats 206 are symmetrically installed at both ends of the movable plate 204, and the symmetrically arranged mounting seats 206 rotate between them. A first rotating rod 207 is movably provided, and a rotating gear 205 meshing with the second rack 203 or the first rack 201 is provided at the end of the first rotating rod 207. A transmission pulley 211 is provided at both ends of the first rotating rod 207. The transmission pulleys 211 located at the same end of the two first rotating rods 207 are connected by a first synchronous belt 212. A first bevel gear 208 is provided on the first rotating rod 207, and a second bevel gear 209 meshing with the first bevel gear 208 is movably provided on the movable plate 204. The second bevel gear 209 is connected to a movable motor 210 installed on the movable plate 204.

[0030] In this embodiment, in the initial state, the movable plate 204 is located inside the operating room 1. When the welding of the hemispherical shell 9 is completed and the hemispherical shell 9 needs to be moved out, the movable motor 210 drives the second bevel gear 209 to rotate forward. The second bevel gear 209 drives the first rotating rod 207 to rotate counterclockwise by being connected to the first bevel gear 208 and the first rotating rod 207 and the mounting seat 206. The first rotating rod 207 drives the transmission pulley 211 and the rotating gear 205 to rotate synchronously. The transmission pulley 211 drives another transmission pulley 211 to rotate synchronously by being connected to the first synchronous belt 212, so that the two first rotating rods 207 rotate synchronously. The rotating gear 205 drives the movable plate 204 to slide with the guide rail 202 by meshing with the second rack 203. The movable plate 204 moves toward the outside of the operating room 1, and the movable plate 204 drives the two supporting rollers 213 to move synchronously. When the supporting rollers 213 come into contact with the placement rack 214, the rotating gear 205 located at one end of the movable plate 204 close to the placement rack 214 meshes with the first rack 201. When the rotating gear 205 continues to rotate counterclockwise, the rotating gear 205 located outside the operating room 1 meshes with the first rack 201 and the rotating gear 205 located inside the operating room 1 meshes with the second rack 203. It can ensure that the movable plate 204 moves smoothly from the inside of the operating room 1 to the placement rack 214. The movable plate 204 drives the hemispherical shell 9 to move synchronously by driving the movable component 3 to move synchronously, thereby realizing the outward movement of the hemispherical shell 9 after welding, which is convenient for taking out the hemispherical shell 9 after welding. The length of the first rack 201 is greater than that of the movable plate 204 , and the height of the first rack 201 is consistent with that of the second rack 203 , so as to facilitate the smooth movement of the movable plate 204 .

[0031] In one embodiment of the present invention, see Figures 1-6 The movable component 3 includes a mounting frame 301 mounted on the movable plate 204, a second rotating rod 302 is rotatably provided in the mounting frame 301, and a third bevel gear 303 is provided on the second rotating rod 302, and a fourth bevel gear 304 is movably provided in the mounting frame 301 that meshes with the third bevel gear 303, and a rotating motor 305 connected to the fourth bevel gear 304 is installed on the mounting frame 301, and the bottom of the second rotating rod 302 passes through the mounting frame 301 and the movable plate 204 and is connected to the first pulley 306, and a first rotating seat 309 is rotatably provided on the movable plate 204, and a second pulley 308 is connected to the bottom of the first rotating seat 309, and the first pulley 306 and the second pulley 308 are connected by a second synchronous belt 307, and a support ring 310 for supporting the hemispherical shell 9 located below is provided on the first rotating seat 309, and a lifting frame 321 is movably provided on the top of the mounting frame 301, and a third rotating rod 316 is rotatably provided on the lifting frame 321, One end of the third rotating rod 316 passes through the mounting frame 301 and is connected to a connecting plate 317 movably provided in the mounting frame 301. The top of the second rotating rod 302 is connected to a guide plate 318. The side of the connecting plate 317 close to the guide plate 318 is connected to a plurality of slide rods 319 that slide with the guide plate 318. The outer side of the second rotating rod 302 is movably provided with a connecting ring 320 connected to the slide rod 319. The outer end of the lifting frame 321 is rotatably provided with a support ring located just above the support ring 310. The second rotating seat 312 is connected to the side of the second rotating seat 312 close to the support ring 310, and is connected to a clamping ring 311 for clamping the hemispherical shell 9 located above. The upper end of the second rotating seat 312 is connected to a third pulley 313, and the upper end of the third rotating rod 316 is connected to a fourth pulley 315. A third synchronous belt 314 is connected between the fourth pulley 315 and the third pulley 313. An electric cylinder 322 connected to the lifting frame 321 is installed on the outer wall of the mounting frame 301; The angle detection assembly 5 includes a plurality of detection pieces 502 equidistantly distributed on the outer wall of the support ring 310 in the circumferential direction. A laser sensor 501 corresponding to the detection pieces 502 is installed on the side of the mounting frame 301 close to the support ring 310 .

[0032] In this embodiment, in the initial state, the support ring 310 supports the hemispherical shell 9 located below, and the clamping ring 311 presses the hemispherical shell 9 located above. The two hemispherical shells 9 are in contact with each other on their sides, and the two hemispherical shells 9 are located between the support ring 310 and the clamping ring 311. Before welding, the annular connection seam between the two hemispherical shells 9 is photographed by the camera 4, and the laser sensor 501 is used to detect the detection pieces 502 at different positions. Since different labels are provided on the detection pieces 502 at different positions, the detection pieces 502 at different positions correspond to different positions of the annular connection seam, so the detection pieces 502 at different positions can reflect the angle of the annular connection seam, so that the image of the annular connection seam taken by the camera 4 corresponds to the detection piece 502 at the corresponding position, and the image of the annular connection seam can reflect the jitter degree of the annular connection seam at the corresponding position, thereby matching the angle and jitter degree of the annular connection seam, and reflecting the connection seam conditions at different angles of the annular connection seam, which is convenient for subsequent adjustment of the position of the electron gun 6. Specifically: the rotating motor 305 drives the second rotating rod 302 to rotate synchronously by driving the fourth bevel gear 304 to rotate, and the second rotating rod 302 is driven by the first pulley 30 6. The second synchronous belt 307 is connected to the second pulley 308 to drive the first rotating seat 309 and the support ring 310 to rotate synchronously, and the support ring 310 drives the hemispherical shell 9 located below to rotate. At the same time, the second rotating rod 302 drives the third rotating rod 316 to rotate synchronously through the sliding cooperation of the guide plate 318 and the sliding rod 319. The third rotating rod 316 drives the second rotating seat 312 and the clamping ring 311 to rotate synchronously through the fourth pulley 315, the third synchronous belt 314 and the third pulley 313. The clamping ring 311 drives the hemispherical shell 9 located above to rotate, thereby realizing the synchronous rotation of the two hemispherical shells 9. The support ring 310 drives several detection pieces 502 to rotate synchronously. The camera 4 takes real-time photos of the connection seam of the two hemispherical shells 9. The laser sensor 501 corresponds to the connection seams of different angles by detecting the detection piece 502, which is convenient for subsequent precision welding processing. The size of the support ring 310 is consistent with that of the clamping ring 311, the size of the third pulley 313 is consistent with that of the second pulley 308, and the size of the first pulley 306 is consistent with that of the fourth pulley 315, which can ensure the synchronous rotation of the two hemispherical shells 9; After the welding of the two hemispherical shells 9 is completed, the movable assembly 3 and the two hemispherical shells 9 can be moved out of the operating room 1 through the moving assembly 2, and the electric cylinder 322 extends upward. The electric cylinder 322 drives the lifting frame 321 to move upward by being connected to the lifting frame 321 and the third rotating rod 316 being movably connected to the mounting frame 301. The lifting frame 321 drives the clamping ring 311 to move upward synchronously by driving the second rotating seat 312 to move upward, thereby releasing the clamping of the upper hemispherical shell 9, facilitating the removal of the hemispherical shell 9 after welding and re-placing the two hemispherical shells 9 to be welded; after the two hemispherical shells 9 to be welded are re-placed, the electric cylinder 322 contracts downward and drives the lifting frame 321 to move downward. The lifting frame 321 drives the clamping ring 311 to move downward synchronously by driving the second rotating seat 312 to move downward, thereby realizing the clamping operation of the upper hemispherical shell 9, thereby facilitating the continuous welding process of the hemispherical shells 9.

[0033] In one embodiment of the present invention, see Figure 1-Figure 7 The adjustment assembly 7 includes a sliding seat 701 slidably arranged on the side of the operating chamber 1 away from the opening, and the electron gun 6 is installed on the sliding seat 701. A connecting cylinder 702 and a sleeve 706 are respectively installed on the side of the sliding seat 701 close to the inside of the operating chamber 1. A second screw 703 threadedly connected to the connecting cylinder 702 is rotatably connected to the inner wall of the operating chamber 1, and one end of the second screw 703 is connected to the adjustment motor 704 installed on the inner wall of the operating chamber 1. A guide rod 705 slidingly matched with the sleeve 706 is installed on the inner wall of the operating chamber 1.

[0034] In this embodiment, through the cooperation of the camera 4, the laser sensor 501 and the detection piece 502, the conditions of the annular connection seam at different angles can be obtained. According to the degree of up and down fluctuation of the annular connection seam, the operating table 106 adjusts the forward and reverse rotation and start and stop of the adjustment motor 704; specifically, when the connection seam fluctuates downward, the operating table 106 controls the adjustment motor 704 to work in the forward direction, and the adjustment motor 704 drives the sliding by driving the second screw 703 to rotate forward, the connecting tube 702 is threadedly connected to the second screw 703, and the sleeve 706 and the guide rod 705 to slide together. The seat 701 moves downward, and the sliding seat 701 drives the electron gun 6 to move downward synchronously, so as to perform corresponding welding processing on the connection seam that fluctuates downward. When the connection seam fluctuates upward, the operating table 106 controls the adjustment motor 704 to work in the reverse direction. The adjustment motor 704 drives the second screw 703 to rotate in the opposite direction, the connecting cylinder 702 is threadedly connected to the second screw 703, and the sleeve 706 and the guide rod 705 are slidably engaged, so as to drive the sliding seat 701 to move upward. The sliding seat 701 drives the electron gun 6 to move downward synchronously, so as to perform corresponding welding processing on the connection seam that fluctuates upward. By adjusting the height of the sliding seat 701, the height of the electron gun 6 is adjusted in real time, which can meet the precision welding requirements of annular connection seams with different degrees of fluctuation. The hemispherical shell 9 can be directly placed on the support ring 310, and the end face runout tolerance can be within the range of ±2mm, avoiding the trouble of repeated clamping and measurement, and improving welding accuracy and welding efficiency.
