Description

Technical Field

[0001] This utility model belongs to the field of welding technology, specifically an automated longitudinal seam welding device. Background Technology

[0002] Longitudinal seam welding refers to the weld formed along the longitudinal or long side of a workpiece. It is usually used to connect rectangular or other long-shaped workpieces. The weld is one or more straight lines extending along the longitudinal direction of the workpiece. The quality requirements for longitudinal seam welding are high. It is necessary to ensure that the weld is flat and uniform, free from defects such as cracks, porosity, and undercut, with a natural and smooth transition and an aesthetically pleasing shape.

[0003] Traditional welding equipment usually requires precise positioning and adjustment by humans to ensure welding quality and efficiency. This not only increases labor intensity, but also often suffers from poor flexibility, making it difficult to achieve precise welding trajectory tracking, resulting in unstable welding quality.

[0004] To address the problems raised in the background art, those skilled in the art have proposed an automated longitudinal seam welding device. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an automated longitudinal seam welding device.

[0010] Preferably, the size of the driving bevel gear is smaller than that of the transmission bevel gear, the lower end of the driving rod is rotatably connected to the moving vehicle, and the upper end of the driving rod is fixedly connected to the support cylinder.

[0011] Preferably, the adjustment assembly includes a support frame fixedly connected to the rotating rod, a mounting plate fixedly connected to the support frame, a second electric push rod fixedly mounted on the mounting plate, a base plate fixedly connected to the second electric push rod, and a welding torch fixedly mounted on the base plate.

[0012] Preferably, the support frame is a U-shaped plate, and the two opposite side plates of the support frame are a short side plate and a long side plate, respectively.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] Example 1

[0025] As attached Figure 1 As shown, this utility model provides an automated longitudinal seam welding device, including a track 1, a moving vehicle 2 connected to the track 1, wherein the moving vehicle 2 moves along the length of the track 1, a steering component 3 is provided on the moving vehicle 2, wherein the steering component 3 is used to control the precise steering of the welding torch 505, the steering component 3 is connected to a pitch component 4, wherein the pitch component 4 can flexibly adjust the angle and height of the welding torch 505, and the pitch component 4 is connected to an adjustment component 5, wherein the adjustment component 5 can finely adjust the position of the welding torch 505 during the welding process to achieve more precise welding control;

[0026] As attached Figure 2 As shown, the pitch assembly 4 includes a first electric push rod 401 fixedly mounted on the mobile vehicle 2. The first electric push rod 401 is fixedly connected to a lifting chamber 402. The extension and retraction of the first electric push rod 401 will cause the height of the lifting chamber 402 to rise or fall. A ball bearing 403 is placed inside the lifting chamber 402. The depth of the lifting chamber 402 is at least the diameter of two balls bearing 403 to prevent the balls bearing 403 from separating from the lifting chamber 402 when the steering assembly 3 rotates. When the steering assembly 3 rotates to the maximum angle... The ball 403 abuts against the side wall inside the lifting chamber 402 to prevent the ball 403 from detaching from the lifting chamber 402. The ball 403 is fixedly connected to a lever 404, and the lever 404 is fixedly connected to a rotating rod 405. The rotating rod 405 is rotatably connected to the support cylinder 406 through a bearing. When the height of the lifting chamber 402 changes, it will drive the ball 403 to rise and fall together, and drive the lever 404 and the rotating rod 405 to rotate around the support cylinder 406 as an axis, thereby changing the angle and height of the adjustment component 5.

[0027] As can be seen from the above, the mobile vehicle 2, carrying the steering assembly 3, the pitch assembly 4, and the adjustment assembly 5, moves along the track 1. The steering assembly 3 controls the precise steering of the welding torch 505 in the adjustment assembly 5. The first electric push rod 401 extends and retracts, causing the lifting chamber 402 to rise and fall. When the height of the lifting chamber 402 changes, it will drive the ball 403 to rise and fall together. The rise and fall of the ball 403 changes the angle of the actuating rod 404. The actuating rod 404 drives the rotating rod 405 to rotate around the support cylinder 406 as the axis, thereby changing the angle and height of the adjustment assembly 5. During the welding process, the adjustment assembly 5 finely adjusts the position of the welding torch 505, thereby achieving more precise welding control.

[0028] Example 2

[0029] As attached Figure 2 As shown, this embodiment is basically the same as the previous embodiment, except that the pitch assembly 4 also includes a guide rod 407 fixedly installed on the upper surface of the moving vehicle 2. A sliding plate 408 is slidably connected to the periphery of the guide rod 407. The sliding plate 408 is fixedly connected to the lifting chamber 402. The guide rod 407 assists the sliding plate 408 and the lifting chamber 402 to move up and down stably and prevents the lifting chamber 402 from deviating during the up and down movement. An anti-detachment plate 409 is fixedly connected to the top of the guide rod 407. The anti-detachment plate 409 is used to prevent the sliding plate 408 and the guide rod 407 from detaching.

[0030] As attached Figure 3 As shown, specifically, the steering assembly 3 includes a base 301 fixedly mounted on the upper surface of the mobile vehicle 2. A drive motor 302 is fixedly mounted on the base 301. A drive bevel gear 303 is fixedly connected to the drive motor 302. The drive bevel gear 303 meshes with a transmission bevel gear 304. The transmission bevel gear 304 is fixedly connected to a drive rod 305. The drive motor 302 drives the drive bevel gear 303 to rotate, thereby driving the transmission bevel gear 304 and the drive rod 305 to rotate.

[0031] As attached Figure 3 As shown, the size of the drive bevel gear 303 is smaller than that of the transmission bevel gear 304, which increases the torque and reduces the rotational speed of the drive rod 305. The lower end of the drive rod 305 is rotatably connected to the moving vehicle 2, and the upper end of the drive rod 305 is fixedly connected to the support cylinder 406.

[0032] As can be seen from the above, the drive motor 302 drives the drive bevel gear 303 to rotate. Since the drive bevel gear 303 meshes with the transmission bevel gear 304, the transmission bevel gear 304 rotates. The rotation of the transmission bevel gear 304 will drive the drive rod 305 to rotate, which in turn drives the pitch assembly 4 and the adjustment assembly 5 to turn. This controls the precise turning of the welding torch 505 in the adjustment assembly 5. When the turning assembly 3 rotates in the horizontal direction, the ball 403 swings in the lifting chamber 402. By setting the size of the lifting chamber 402, the ball 403 is prevented from disengaging from the lifting chamber 402.

[0033] Example 3

[0034] As attached Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that the adjustment component 5 includes a support frame 501 fixedly connected to the rotating rod 405, a mounting plate 502 fixedly connected to the support frame 501, and a second electric push rod 503 fixedly mounted on the mounting plate 502. The second electric push rod 503 will drive the welding gun 505 to make fine adjustments. The second electric push rod 503 is fixedly connected to a base plate 504, and the welding gun 505 is fixedly mounted on the base plate 504. The longitudinal seam welding work is performed through the welding gun 505.

[0035] As attached Figure 4 As shown, specifically, the support frame 501 is a "U" shaped plate. The two opposite side plates of the support frame 501 are a short side plate and a long side plate, respectively. The short side plate is fixedly connected to the rotating rod 405, and the long side plate is fixedly connected to the mounting plate 502.

[0036] As can be seen from the above, the position of the welding torch 505 is changed by moving the mobile carriage 2 on the track 1, the steering component 3 can precisely control the horizontal direction of the welding torch 505, the pitch component 4 can flexibly adjust the angle and height of the welding torch 505, and the second electric push rod 503 can finely adjust the position of the welding torch 505 during the welding process to achieve more precise welding control; the mobile carriage 2, the first electric push rod 401, the drive motor 302 and the second electric push rod 503 are programmed and controlled by the PLC controller to realize automated longitudinal seam welding.
