[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 2 , Figure 4 and Figure 5 This utility model provides an embodiment of a plate clamping device for laser welding, comprising a body 1 as the basic support for the entire device. A sliding groove 3 is provided inside the body 1, and a sliding block 4 is slidably connected to the inner wall of the sliding groove 3. Due to the restriction of the sliding groove 3, the sliding block 4 can only move left and right. A threaded rod 5 is rotatably connected to the middle of the inner wall of the sliding groove 3, and the outer wall of the threaded rod 5 is threadedly connected to the sliding block 4. When the threaded rod 5 rotates, it drives the sliding block 4 to move. A motor 15 is fixedly connected to the right end of the body 1, and the output end of the motor 15 is fixedly connected to the right end of the threaded rod 5. When the motor 15 works, it drives the threaded rod 5 to rotate. A second sliding groove 22 is provided inside the sliding groove 3 to restrict the suction plate 6 to move only back and forth. The suction plate 6 is slidably connected to the inner wall of the second sliding groove 22. For adsorbing plates, the inner wall of the sliding groove 22 is rotatably connected to the threaded rod 7. The outer wall of the threaded rod 7 is threadedly connected to the suction plate 6. The rotation of the threaded rod 7 drives the suction plate 6 to move. The rear side of the machine body 1 is fixedly connected to the slide plate 10. The slide plate 10 is used to support the weight of the motor 13. The top rear side of the slide plate 10 is provided with a limit groove 11. The limit groove 11 is used to limit the sliding block 12 so that it can move left and right along the limit groove 11. The inner wall of the limit groove 11 is slidably connected to the sliding block 12. The sliding block 12 is used to drive the motor 13 to move. The top of the sliding block 12 is fixedly connected to the motor 13. The output end of the motor 13 is fixedly connected to the threaded rod 7. When the motor 13 moves, it drives the threaded rod 7 to rotate. The top left side of the machine body 1 is fixedly connected to the dust collection mechanism 2. The dust collection mechanism 2 is used to absorb the residue and debris generated when the machine is working.

[0026] Specifically, because sliding groove 3 restricts sliding block 4 to only move left and right, and sliding groove 22 restricts suction plate 6 to only move forward and backward, and sliding groove 22 is connected to threaded rod 5, which is connected to motor 15, motor 15 can control the plate to move left and right when it is started. Suction plate 6 is connected to threaded rod 27, which is connected to motor 23, so the forward and backward direction can be controlled by starting motor 23 during use.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The vacuuming mechanism 2 includes a gantry frame 201 and a vacuum box 210. The bottom of the gantry frame 201 is fixed to the top left side of the body 1 to bear the weight. A fixed plate 202 is fixedly connected to the inner wall of the gantry frame 201 to support the rack 203 and bear the weight of the motor 205 and the sliding block 207. The rack 203 is fixedly connected to the top left side of the fixed plate 202. A limiting groove 211 is opened on the top right side of the fixed plate 202. A sliding block 207 is slidably connected to the front side of the inner wall of the limiting groove 211. The sliding block can only move back and forth because of the limiting groove 211. The top of the sliding block 207 is fixedly connected to a motor 205. The left side of the motor 205 is fixedly connected to a gear 204. The gear 204 meshes with the rack 203, allowing the motor 205 to move through the gear 204. The bottom of the sliding block 207 is fixedly connected to a fixed box 206. The bottom of the fixed box 206 is fixedly connected to a suction port 208. The front end of the fixed box 206 is connected to a suction pipe 209. The bottom of the suction pipe 209 is connected to a suction box 210. The suction box 210 transmits suction power to the suction port 208 through the suction pipe 209.

[0028] Specifically, the gantry 201 serves as the weight support for the entire mechanism, supporting other components. The dust collection box 210 is the source of suction power. The gantry 201 is used to fix the fixed plate 202. When the motor 205 starts, the left gear 204 moves back and forth on the rack 203. Since the gear 204 is connected to the motor 205, the motor 205 also moves back and forth. The motor 205 is connected to the sliding block 207, which is connected to the fixed box 206. The fixed box 206 is connected to the suction port 208. The sliding block 207 is restricted by the limiting groove 211. Therefore, when the motor 205 starts, it can only move back and forth, which will drive the suction port 208 to move back and forth. The dust collection box 210 is connected to the fixed box 206 through the suction pipe 209. The fixed box 206 and the suction port 208 are also connected. Therefore, when the dust collection box 210 starts, the suction port 208 generates suction power.

[0029] Reference Figure 1 , Figure 4 and Figure 5The front end of the threaded rod 7 is fixedly connected to a rotating handle 20 for manual control of the threaded rod 7 in an emergency. The right end of the threaded rod 5 is fixedly connected to a rotating handle 21 for manual control of the threaded rod 5 in an emergency. The outer walls of the machine body 1 are all fixedly connected to fixed seats 9. The bottom of the fixed seat 9 is fixedly connected to a positioning hole 16, which is mainly used to fix the entire machine. The top of the suction plate 6 is fixedly connected to a buffer pad 8 to reduce the damage caused by direct contact between the plate and the suction plate 6. The top surface of the buffer pad 8 is provided with multiple suction holes 24. The suction holes 24 and the holes on the upper part of the suction plate 6 are aligned so as not to affect the suction force.

[0030] Specifically, the rotating handle 20 connected to the front end of the threaded rod 7 can rotate the threaded rod 7 in an emergency. The rotating handle 21 connected to the right end of the threaded rod 5 can rotate the threaded rod 5 in an emergency. The fixing seat 9, together with the positioning hole 16, can fix the entire machine. The buffer pad 8 on the top of the suction plate 6 is mainly to buffer the plate and the suction plate 6 to reduce the probability of damage to the plate. The suction hole 24 on the top is mainly to align the holes of the suction plate 6 so as not to affect the adsorption effect.

[0031] Reference Figure 1 , Figure 2 and Figure 5 A second sliding plate 23 is fixedly connected to the bottom left side of the machine body 1. Guardrails 14 are fixedly connected to the front and rear sides of the second sliding plate 23 to fix the second motor 13. A display 17 is fixedly connected to the front right side of the machine body 1 to display some data. Multiple buttons 18 are fixedly connected to the front right side of the display 17 to control the display 17. Multiple scale slots 19 are opened on the top front side of the machine body 1. The spacing between the multiple scale slots 19 is the same to measure the distance moved during operation.

[0032] Specifically, the sliding plate 23 and the guardrail 14 are used together to hold the motor 2 13 to prevent it from falling, while the display 17 can display some data during operation, the button 18 is used to control the display 17, and the scale groove 19 is used to monitor the specific distance when the plate moves.

[0033] Working principle: The sheet metal to be welded is placed on the suction plate 6. The suction plate 6 uses its own adsorption function to firmly fix the sheet metal on its surface, providing a stable foundation for subsequent operations. When it is necessary to adjust the left or right position of the sheet metal, motor 15 is started. Motor 15 serves as a power source, and its output end is fixedly connected to the right end of threaded rod 5. When motor 15 runs, it drives threaded rod 5 to rotate. Since the outer wall of threaded rod 5 is threadedly connected to sliding block 4, and sliding block 4 is slidably connected to the inner wall of sliding groove 3, sliding groove 3 provides resistance to sliding blocks. Block 4 acts as a limit, ensuring that it can only slide left and right within the sliding groove 3. Since block 4 and the suction plate 6 are fixed together, the left and right movement of block 4 will cause the suction plate 6 and the plate material adsorbed on it to move left and right synchronously, thus achieving precise alignment of the plate material's left and right positions and ensuring accurate lateral positioning of the plate material during laser welding. To adjust the front and back position of the plate material, motor 13 is started. The output end of motor 13 is fixedly connected to threaded rod 7. After motor 13 is started, it carries... The rotating threaded rod 7 connects the outer wall of the threaded rod 7 to the suction plate 6, while the suction plate 6 is slidably connected to the inner wall of the sliding groove 22. The sliding groove 22 restricts the movement direction of the suction plate 6, allowing it to slide back and forth within the sliding groove 22. In this way, the rotation of the threaded rod 7 drives the suction plate 6 and the plate to move back and forth, thereby completing the precise adjustment of the plate's front and back position. This ensures that the plate meets the welding requirements in the longitudinal direction as well. In addition, the structure composed of components such as the sliding plate 10, the limiting groove 11, and the sliding block 12 on the rear side of the machine body 1 provides stable support and guidance for the motor 13 and related transmission components, ensuring the stability and reliability of the motor 13 when driving the threaded rod 7. This allows the entire process of adjusting the plate's front and back position to proceed smoothly and precisely. By controlling the threaded rod 5 and the threaded rod 7 respectively through the motor 15 and the motor 13, the position adjustment of the plate in both left and right and front and back dimensions is achieved. This ensures that the plate can be accurately placed in the appropriate position before laser welding, laying a solid foundation for high-quality laser welding operations.

[0034] Furthermore, when motor 3 205 starts, the left gear 204 connected to it moves back and forth on rack 203. Since gear 204 is directly connected to motor 3 205, motor 3 205 moves back and forth accordingly. Motor 3 205 is also connected to sliding block 3 207, which is fixed together with fixed box 206. Fixed box 206 is connected to suction port 208. In addition, sliding block 3 207 is restricted by limiting groove 211, which means that motor 3 205 can only move back and forth after starting, thereby driving suction port 208 to move in a certain direction. The vacuum chamber 210 moves back and forth within its range to adjust the position of the suction port 208. In terms of suction function, the vacuum chamber 210 serves as the suction source and is connected to the fixed box 206 through the suction pipe 209. The fixed box 206 is in turn connected to the suction port 208. When the vacuum chamber 210 starts working, the suction force it generates is transmitted to the fixed box 206 and the suction port 208 through the pipe, so that the suction port 208 generates suction force, thereby completing the vacuuming operation of a specific area. Through the coordinated cooperation of various components, the mechanism achieves the functions of stable support, position adjustment and effective vacuuming.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
