Description

Technical Field

[0001] This invention relates to the field of irregular part welding technology, specifically to an irregular part welding machine. Background Technology

[0002] Irregularly shaped parts, as the name suggests, refer to parts or workpieces with irregular or non-standard shapes. The shape, structure, size, or material properties of irregularly shaped parts make them impossible to classify into existing standard parts catalogs, and they often need to be processed or customized according to specific design requirements.

[0003] A search revealed a Chinese patent with application number "CN202510087078.X", which is specifically a welding equipment for processing irregularly shaped tubes for electric vehicles. The equipment includes a housing, a rotating shaft rotatably connected to the inner wall of the housing, a protective cover fixedly connected to the outer surface of the rotating shaft, and a pressing component fixedly connected to the upper surface of the housing. The circumferential device can also cause the roller to roll against the outer surface of the irregularly shaped tube while driving the roller to rotate circumferentially.

[0004] When welding existing elliptical tubes, the two ends of the tubes are placed on the welding table, and the welding torch is controlled to rotate around the tubes. The welding torch welds the two ends of the tubes together. However, after welding, the welded tubes are blocked by the semi-circular guide rail, making it difficult to remove the tubes. When there are many tubes to be welded, this increases the workload of the workers.

[0005] Therefore, the present invention proposes a welding machine for irregularly shaped parts to solve the problems mentioned above. Summary of the Invention

When welding the two irregular tubes 4, the hydraulic cylinder 318 is controlled to drive the welding torch 319 to descend, so that the welding torch 319 welds with the irregular tube 4. At the same time, the motor 323 is started, and the motor 323 drives the mounting rod 321 to rotate. The mounting rod 321 drives the gear 322 to rotate. Since the gear 322 meshes with the gear ring 38, the welding torch 319 is controlled to rotate, so that the welding torch 319 welds the annular weld.

[0032] The material discharge unit 5 includes two lifting plates 51, both of which are located inside the welding box 1. A rectangular hole 52 is formed on the outer side of each lifting plate 51.

Since the two inclined plates 311 are symmetrically distributed, the connecting blocks 34 on the upper and lower sides are separated. The connecting block 34 drives the slider 33 to move, the slider 33 drives the fixing block 35 to move, and the fixing block 35 drives the semi-circular guide rail 36 to move.

When discharging the irregular tube 4, the U-shaped plate 53 drives the lifting frame 59 to rise. The lifting frame 59 pushes the irregular tube 4 up, which facilitates the removal of the irregular tube 4. The pulleys 510 facilitate the extraction of the irregular tube 4.

Rotating blocks 1 519 are fixedly connected to the lower side of both left and right sliding blocks 2 512. Linkage plates 1 520 are rotatably connected to the outer side of both rotating blocks 1 519. Rotating blocks 2 521 are rotatably connected to the outer side of linkage plates 1 520. Push blocks 2 527 are fixedly connected to the lower side of rotating blocks 2 521. Rotating blocks 3 523 are fixedly connected to the lower side of both sliding blocks 3 516. Linkage plates 2 524 are rotatably connected to the outer side of both rotating blocks 3 523. Rotating blocks 4 525 are rotatably connected to the outer side of linkage plates 2 524. The lower side of rotating blocks 4 525... A push block 526 is fixedly connected to the lifting plate 51. Both push blocks 526 and 527 are fixedly connected to the lifting plate 51.

During material discharge, the lifting plate 51 drives push blocks 526 and 527 to rise, and push blocks 526 drives linkage plate 524 to rotate. Due to the symmetrical distribution of the two linkage plates 524, the linkage... Moving plate 2 524 drives slider 3 516 to move, slider 3 516 drives L-shaped block 2 517 to move, L-shaped block 2 517 drives clamping block 2 518 to move, so that clamping blocks 2 518 on both sides separate from the shaped tube 4. At the same time, pushing block 2 527 drives linkage plate 1 520 to rotate, linkage plate 1 520 drives slider 2 512 to move, slider 2 512 drives L-shaped block 1 513 to move, L-shaped block 1 513 drives clamping block 1 514 to move, so that clamping blocks 1 514 on both sides separate from the shaped tube 4.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During operation, when welding the shaped tube 4, the hydraulic cylinder 318 lowers the welding torch 319, bringing it into contact with the tube 4. The motor 323 then drives the mounting rod 321, which in turn rotates the gear 322. Under the action of the gear ring 38, the welding torch 319 rotates, facilitating the welding of the annular weld. After welding, the electric push rod 56 raises the lifting block 55, which in turn raises the U-shaped plate 53. Under the action of the stabilizing block 54, the lifting plate 51 rises, which in turn raises the connecting plate 315. The gear ring 314 and gear 313... Under the action of the rotating rod 39, the control plate 310 rotates. Under the action of the inclined plate 311, connecting rod 312, connecting block 34, slider 1 33 and fixing block 35, the semi-circular guide rails 36 on the upper and lower sides separate from each other, providing sufficient space for the removal of the shaped tube 4. At the same time, the U-shaped plate 53 drives the lifting frame 59 and pulley 510 to rise, pushing out the shaped tube 4. Simultaneously, under the action of the linkage plate 1 520, linkage plate 2 524, slider 2 512 and slider 3 516, clamping block 1 514 and clamping block 2 518 separate from the shaped tube 4, facilitating quick contact of the clamp and making operation simple.
