[0040] In this embodiment, as Figure 1And Figure 2 As shown, a workbench for a gantry welding machine includes a welding machine body 1 and a workbench 2. An adjusting device 3 is installed on the workbench 2. The adjusting device 3 is used to flip the workbench 2. The adjusting device 3 includes a support shaft 31, a carrier 32, a grooved pulley 33 and a fixing member 34. The workbench 2 is rotatably connected to the carrier 32 through the support shaft 31. The support shaft 31 drives the workbench 2 to flip in the carrier 32. The grooved pulleys 33 are fixedly connected to both ends of the support shaft 31. The fixing member 34 restricts the rotational movement of the support shaft 31, thereby limiting the use position of the workbench 2.

[0041] Thus, by rotating the support shaft 31 in the carrier 32, the support shaft 31 drives the workbench 2 to flip. Subsequently, the fixing member 34 is used to fix the positions of the grooved pulleys 33 at both ends of the support shaft 31, so that the workbench 2 is in a vertical state or a horizontal state. When the workbench 2 is in a vertical state, the welding slag remaining on the workbench 2 directly falls off. When the workbench 2 is in a horizontal state, it is used to carry the workpiece to be welded.

[0042] Furthermore, the workbench 2 is arranged at the bottom of the welding machine body 1. The support shaft 31 rotates in the carrier 32 through a bearing. Grooved pulleys 33 are fixedly connected to both ends of the support shaft 31. Four grooves are annularly distributed in the grooved pulley 33.

[0043] In some embodiments, as Figure 2 shown, the fixing member 34 includes a telescopic member 341, a connecting plate 342, a pin 343 and a guiding rod 344. The telescopic member 341 is fixedly connected to the outer wall of the carrier 32. The connecting plate 342 is fixedly connected to the output end of the telescopic member 341. The bottom of the pin 343 is fixedly connected to the connecting plate 342. The pin 343 is inserted into the groove of the grooved pulley 33 to restrict the rotational movement of the support shaft 31. The guiding rod 344 is sleeved in the connecting plate 342, and the bottom end of the guiding rod 344 is fixedly connected to the carrier 32.

[0044] Furthermore, the telescopic member 341 is an electric push rod. The connecting plate 342 moves along with the output end of the telescopic member 341. The pin 343 is cylindrically embedded in the groove of the grooved pulley 33 to fix the support shaft 31. The guiding rod 344 arranged in the connecting plate 342 enables the connecting plate 342 to move in the vertical direction.

[0045] In some embodiments, as Figure 3 shown, a fixing device 4 is fixedly connected in the carrier 32. The fixing device 4 cooperates with the workbench 2 in the vertical state to clamp the workpiece to be welded. The fixing device 4 includes a transmission member 41, a fine-tuning member 42 and a clamping plate 43. The transmission member 41 is used to drive the clamping plate 43 to move. The clamping plate 43 cooperates with the workbench 2 to clamp the workpiece to be welded. The fine-tuning member 42 is used to perform multi-point fixation on the workpiece to be welded.

[0046] Further, when the workbench 2 is in a vertical state, place the workpiece to be welded between the workbench 2 and the clamping plate 43. Drive the clamping plate 43 to move through the transmission of the transmission member 41 to fix the welding workpiece, and realize multi-point fixation of the workpiece by adjusting the fine-tuning member 42 in the clamping plate 43, thereby improving the clamping degree of the welding workpiece.

[0047] In some embodiments, as Figure 3 shown, the transmission member 41 includes a mounting shell 411, a transmission shaft 412, a sliding seat 413 and a motor 414. The mounting shell 411 is fixedly connected in the carrier 32. The transmission shaft 412 is rotatably connected to the mounting shell 411 through a bearing. The sliding seat 413 is threadedly connected to the transmission shaft 412. The sliding seat 413 passes through the chute at the top of the mounting shell 411 and is connected to the clamping plate 43. When the transmission shaft 412 rotates, it drives the clamping plate 43 to move through the sliding seat 413. The motor 414 is connected to the transmission shaft 412 through a coupling.

[0048] Further, a cavity is machined in the mounting shell 411. A strip-shaped groove is machined at the top of the mounting shell 411 to limit the horizontal movement of the sliding seat 413. The motor 414 is a servo motor that provides power for the rotation of the transmission shaft 412.

[0049] In some embodiments, as Figure 3 shown, the fine-tuning member 42 includes a screw 421 and a top block 422. The screw 421 is internally threaded with the clamping plate 43. The top block 422 is fixedly connected to the screw 421. The screw 421 drives the top block 422 to move horizontally to fix the workpiece to be welded.

[0050] Further, three screws 421 are provided in the clamping plate 43. The top block 422 is made of rubber material. After the clamping plate 43 preliminarily fixes the welding workpiece, the workpiece is secondarily fixed by adjusting the top block 422, increasing the clamping degree of the welding workpiece.

[0051] In some embodiments, as Figure 4 and Figure 5 shown, a sliding device 5 is provided at the bottom of the carrier 32. The sliding device 5 includes a sliding member 51 and a braking member 52. The sliding member 51 drives the carrier 32 and the workbench 2 to move horizontally, and the braking member 52 brakes the sliding member 51.

[0052] Further, the setting of the sliding member 51 facilitates adjusting the use position of the workbench 2, and the braking member 52 fixes the position of the adjusted workbench 2.

[0053] In some embodiments, as Figure 6As shown, the sliding member 51 includes a bottom plate 511, a pulley 512, and a slide rail 513. The bottom plate 511 is fixedly connected to the bottom of the carrier 32. The bottom plate 511 is slidably connected through the pulley 512 and the slide rail 513, and the bottom plate 511 drives the carrier 32 and the workbench 2 to move horizontally.

[0054] Further, the bottom plate 511 bears the workbench 2 on the carrier 32. Four pulleys 512 are provided at the bottom of the bottom plate 511, and the slide rail 513 is in the shape of a "work" character.

[0055] In some embodiments, as Figure 5 shown, a plurality of reinforcing ribs are equidistantly arranged in the slide rail 513.

[0056] Further, the use of the reinforcing ribs increases the connection strength between the two slide rails 513.

[0057] In some embodiments, as Figure 6 shown, the braking member 52 includes a threaded sleeve 521, a connecting rod 522, and a brake disc 523. The threaded sleeve 521 is fixedly connected in the bottom plate 511. The connecting rod 522 is threadedly connected in the threaded sleeve 521. The brake disc 523 is fixedly connected to the bottom end of the connecting rod 522. The brake disc 523 abuts against the slide rail 513 to realize the braking of the pulley 512.

[0058] Further, two threaded sleeves 521 are provided in the bottom plate 511. The outer wall of the connecting rod 522 is processed with threads. The lower surface of the brake disc 523 is processed with strip-shaped lines. The design of the strip-shaped lines increases the friction between the brake disc 523 and the slide rail 513.

[0059] In some embodiments, as Figure 1 shown, the workbench 2 further includes a grooved surface 21, and the grooved surface 21 is distributed on both sides of the workbench 2.

[0060] Further, grooved surfaces 21 are provided on both the upper and lower sides of the workbench 2. The design of the grooved surfaces 21 increases the friction between the workbench 2 and the workpiece to be welded.

[0061] Working principle:

[0062] When the workbench 2 is in a horizontal state, the workpiece to be welded is placed on the upper surface of the workbench 2. By moving the pulley 512 in the slide rail 513, the pulley 512 drives the bottom plate 511, the bearing frame 32 and the workbench 2 to move into the welding machine body 1 together. Rotate the connecting rod 522 to drive the brake disc 523 to move. After the brake disc 523 is in close contact with the slide rail 513, fix the position of the pulley 512 on the slide rail 513. At this time, welding processing is carried out. When it is necessary to change the use position of the workbench 2, start the telescopic member 341. The output end of the telescopic member 341 drives the pin 343 to separate from the groove wheel 33 through the connecting plate 342. Then, the workbench 2 is flipped in the bearing frame 32. As a result, the workbench 2 is in a vertical state. At this time, the welding slag remaining on the workbench 2 automatically falls off. Place the workpiece to be welded between the clamping plate 43 and the workbench 2. Start the motor 414 to drive the transmission shaft 412 to rotate in the installation shell 411. Then, drive the sliding seat 413 to move along the chute at the top of the installation shell 411. The sliding seat 413 drives the clamping plate 43 to move towards the workbench 2. Then, the clamping plate 43 cooperates with the workbench 2 to clamp the welding workpiece. At this time, the settings of the workbench 2 and the clamping plate 43 play the role of a fixture for fixing the workpiece to be welded. Rotate the screw rod 421 to drive the top block 422 to fix the workpiece secondly, thereby increasing the clamping degree of the welding workpiece.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
