Description

Technical Field

[0001] The invention relates to the technical field of welding devices, and in particular to a welding device for shelf processing and production. Background Art

[0002] Shelves generally refer to racks for storing goods. Shelves are storage equipment used to store finished items. According to their uses, they can be divided into supermarket shelves, storage shelves, display shelves, and storage shelves are divided into light shelves, medium shelves, heavy shelves, etc.

[0003] Publication number CN 118650342 A discloses a welding device for manufacturing steel pipe shelves. During the welding process, the shelf crossbar is kept vertically set in the transition sleeve, and no manual support is required, which improves the welding efficiency. The transition sleeve can be rotated to be set horizontally and vertically. The transition sleeve when set horizontally is convenient for inserting and loading the shelf crossbar, which is convenient and easy to operate. Publication number CN 118357622 A discloses a shelf crossbeam welding device. Two movable plates move relative to each other, driving two fixed rods to move. The two fixed rods drive the hinged rods to move, driving the slider to slide on the inner wall of the cross arc groove, and the slider drives the support rod to move. Under the joint action of the support rod and the slide rod, the two clamping plates are close to each other to clamp and fix the front and rear sides of the shelf crossbeam. On the basis of the fixing mechanism fixing the shelf crossbeam, the shelf crossbeam is further fixed, so that the shelf crossbeam is not easy to deviate during welding, thereby improving the quality of welding.

[0004] A shelf usually includes four shelf columns and several shelf beams. When welding the shelf, it is necessary to weld several shelf beams to the shelf columns in sequence. Although the two prior arts disclosed above are convenient for clamping and fixing the shelf columns and the shelf beams, thereby facilitating welding of the shelf columns and the shelf beams, the prior arts disclosed above all clamp and fix a certain shelf column and a certain shelf beam at a time. After welding, the shelf columns and the shelf beams need to be removed, and then the other shelf beams and shelf columns need to be welded. Since each welding is only performed on one of the shelf columns and the shelf beams, only part of the shelf can be welded each time. Afterwards, multiple shelves that have been welded need to be assembled and welded again, so that the parts of multiple shelves are welded together as a whole to complete the welding of the shelves. The overall operation process is cumbersome and inefficient. Summary of the invention

[0006] In view of this, the purpose of the invention is to propose a welding device for shelf processing and production.

When the second tooth plate and the first tooth plate are separated, the movable plate is moved down to drive the rotating rod to rotate. When the rotating rod rotates, it drives the second concave plate and the second contact plate to move, so that the second contact plate clamps the shelf column in the second storage cavity, that is, the position of the shelf column is fixed.

[0021] Furthermore, in the present invention, when the movable plate moves downward, it drives the pressing plate, the piston rod, and the third piston to move downward. When the third piston moves downward, it squeezes the air in the cylinder into the L-shaped air pipe, so that the air in the L-shaped air pipe is squeezed into the connecting pipe, and the air in the connecting pipe is squeezed into the curved pipe and the straight pipe.

In the storage cavity, that is, when the movable plate moves downward, the effect it produces is not only to make the second contact plate clamp the shelf column in the second storage cavity, but also to make the first contact plate clamp the first beam of the shelf in the first storage cavity, and to make the third contact plate clamp the second beam of the shelf in the third storage cavity, that is, the shelf column, the first beam of the shelf, and the second beam of the shelf can be fixed simultaneously and synchronously. When the shelf column, the first beam of the shelf, and the second beam of the shelf are fixed simultaneously and synchronously, the splicing of the entire frame of the shelf is completed, and the overall welding can be carried out without multiple local splicing and welding. The device can complete the positioning and splicing of the entire outer frame at one time, which is convenient for welding work and improves the efficiency of shelf welding.

[0022] Furthermore, the shelf columns, the first crossbeam of the shelf, and the second crossbeam of the shelf can be fixed simultaneously and synchronously, which can achieve precise docking without repeatedly adjusting any of the components to cause deformation and dislocation of the overall structure, especially during the welding process. Since the temperature of the welding part is high and there is internal stress, if the position of a component is fine-tuned and welded again at this time, the internal stress of the overall structure will further increase, reducing the stability of the overall structure of the shelf. Therefore, this solution can avoid fine-tuning the position of any component during welding, thereby avoiding the increase of internal stress of the overall structure after welding due to fine-tuning, and thus can improve the overall welding quality of the shelf.

[0051] When part of the air in the connecting tube 226 is squeezed into the curved tube 224, the air in the curved tube 224 squeezes the second piston 239 and drives the second piston 239 to move. When the second piston 239 moves, it drives the second push rod 238 to move. When the second push rod 238 moves, it drives the third inner concave plate 233 and the third contact plate 234 to move, so that the third contact plate 234 clamps the second cross beam 107 of the shelf in the third storage cavity 240. That is, when the moving plate 213 moves downward, not only the second contact plate 207 clamps the shelf column 105, but also the second contact plate 207 clamps the shelf column 105. In the second storage cavity 208, the first contact plate 204 clamps the first shelf beam 106 in the first storage cavity 205, and the third contact plate 234 clamps the second shelf beam 107 in the third storage cavity 240, that is, the shelf column 105, the first shelf beam 106, and the second shelf beam 107 can be fixed synchronously. At this time, the shelf column 105, the first shelf beam 106, and the second shelf beam 107 form the overall frame of the shelf, and then the welding device 110 can be pulled down to perform welding;

[0052] After the welding of the first crossbeam 106, the second crossbeam 107 and the column 105 of the same layer is completed, the movable plate 213 is moved upward, so that the second contact plate 207 no longer clamps the column 105, and the first contact plate 204 no longer clamps the first crossbeam 106 of the shelf, and the third contact plate 234 no longer clamps the second crossbeam 107 of the shelf, and then the hydraulic cylinder 115 extends to drive the disc 116, the second connecting rod 117, and the support plate 118 to move upward, thereby driving the welded column 105, the first crossbeam 106 of the shelf, and the second crossbeam 107 of the shelf to move upward as a whole, and then the first crossbeam 106 and the second crossbeam 107 of the shelf that need to be newly welded are placed in the corresponding first storage cavity 205 and the third piston 245, and then the movable plate 213 is moved downward, so that the column 105 and the newly replaced first crossbeam 106 and the second crossbeam 107 of the shelf can be fixed synchronously again, and welding can be performed again.
