Description

Technical Field

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater and in space.

[0003] When producing some steel bars, due to their insufficient length, multiple groups of steel bars need to be welded together to produce them into suitable lengths. However, when using existing steel bar welding devices, when welding multiple groups of steel bars, the operator needs to place two groups of steel bars on the processing table and support them with hands. Supporting the workpiece being welded with hands may pose a safety hazard, and the steel bars lack limit stops. When welding two new groups of steel bars, the joints of the two groups of steel bars to be welded need to be adjusted multiple times, which is troublesome to operate.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a welding production line is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Furthermore, the two groups of movable plates 10 are both inclined, and the two groups of movable plates 10 form a rotating structure through the two groups of control plates 9. When the two groups of moving rings 8 move, they will respectively apply thrust to the movable plates 10 connected to their own rotation, so that the movable plates 10 rotate around the connection with the moving rings 8.

[0025] Furthermore, the connection points between the two groups of movable plates 10 and the two groups of clamping plates 11 are both located at the rear end thereof. The two groups of clamping plates 11 respectively drive the two groups of telescopic plates 13 through the two groups of movable plates 10 to form a telescopic structure. When the two groups of movable plates 10 rotate, they will respectively drive the clamping plates 11 connected to their own rotation to move toward the center of the mounting ring 5. At this time, the two groups of clamping plates 11 will clamp and fix the two groups of welding workpieces 19.

[0026] Furthermore, the centers of the two sets of connecting rings 3 and the two sets of mounting rings 5 ​​are located at the same point, and the two sets of mounting rings 5 ​​form a rotating structure on the inner wall of the connecting ring 3 through the two sets of gears 6. When the two sets of racks 22 move, a rotational force is applied to the two sets of gears 6, so that the two sets of gears 6 drive the two sets of mounting rings 5 ​​and the two sets of connecting rods 4 to rotate along the inner wall of the connecting ring 3.

[0027] Embodiment 2: Figure 3 - Figure 4 As shown, a second electric push rod 14 fixedly connected to the processing table 1 is provided in the middle of the two groups of mounting rings 5, a connecting plate 15 is fixedly connected to the output end of the second electric push rod 14, racks 22 meshing with the two groups of gears 6 are fixedly connected to both sides of the connecting plate 15, a placing table 17 located on one side of the clamping plate 16 is fixedly connected to the top of the processing table 1, two groups of clamping plates 16 are slidably connected to the surface of the placing table 17, and the sides of the two groups of clamping plates 16 are fixedly connected to second springs 18 fixedly connected to the placing table 17, a support plate 20 is fixedly connected to the top of the processing table 1, and a spot welding head 21 is fixedly connected to the bottom of the support plate 20.

[0028] Furthermore, the two groups of clamping plates 16 are arranged parallel to each other, and the two groups of clamping plates 16 form a sliding structure through two groups of second springs 18. By arranging the second springs 18, the clamping plates 16 can limit the welding workpieces 19 of different sizes.

[0029] Furthermore, the transverse center axis of the placement table 17 and the centers of the two sets of clamping plates 11 are located on the same horizontal line, which helps to push the welding workpiece 19 placed on the placement table 17 to the clamping plates 11.

[0030] Working principle: When using the welding production line, first, place the welding workpiece 19 to be welded between the two sets of clamping plates 16. The two sets of clamping plates 16 will limit the welding workpiece 19 under the action of the second spring 18. Then, insert the welding workpiece 19 into the inside of the set of clamping plates 11 on the right side, and make the left side of the welding workpiece 19 under the spot welding head 21. Then, push the welding workpiece 19 on the placement table 17 to pass through the clamping plate 11 on the right side and contact with the other set of welding workpieces 19. At this time, the setting can be turned on. The first electric push rod 7 on the side of the two sets of gears 6 is used to push the two sets of moving rings 8 at the same time. When the two sets of moving rings 8 move, they will respectively apply thrust to the movable plates 10 connected to their own rotation, so that the movable plates 10 rotate around the connection with the moving rings 8. When the two sets of movable plates 10 rotate, they will respectively drive the clamping plates 11 connected to their own rotation to move toward the center of the mounting ring 5. At this time, the two sets of clamping plates 11 will clamp and fix the two sets of welding workpieces 19. Then, the connection of the two sets of welding workpieces 19 is welded by the spot welding head 21.

[0031] After welding is completed, the two groups of clamping plates 11 can be controlled by the two groups of first electric push rods 7 to release the welded workpieces 19, and push the position of the welded workpieces 19 on the placement table 17, so that the welded workpieces 19 slide to the right as a whole, so that the joint that has just been welded moves to the clamping plate 11 on the right, and the left end is located below the spot welding head 21. At this time, a new group of welding workpieces 19 is placed on the placement table 17 and pushed to move so that the right port contacts with another group of welding workpieces 19, and the joints are welded again by the spot welding head 21. After welding is completed, the operation of placing a new group of welding workpieces 19 is repeated again, and this cycle is repeated until the workpieces of appropriate length are welded. During the welding process, the worker only needs to push the workpiece to be welded, and there is no need to adjust the workpiece as a whole to avoid the problem of welding point offset.

[0032] Next, in order to enable the spot welding head 21 to weld the joints of the two groups of welding workpieces 19 in all directions during welding, when the two groups of clamping plates 11 clamp the two groups of welding workpieces 19, the second electric push rod 14 can be opened to pull the connecting plate 15, and the connecting plate 15 will drive the two groups of racks 22 to move. When the two groups of racks 22 move, a rotational force will be applied to the two groups of gears 6, so that the two groups of gears 6 drive the two groups of mounting rings 5 ​​and the two groups of connecting rods 4 to rotate along the inner wall of the connecting ring 3. At this time, the two groups of welding workpieces 19 fixed on the inner walls of the two groups of clamping plates 11 will also rotate together, so as to achieve all-round welding of the joints of the two groups of welding workpieces 19.

[0033] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
