Description

Technical Field

[0001] The utility model relates to the technical field of welding processing, and more specifically, to a processing device for welding long-axis rods. Background Art

[0002] Welding, also known as fusion or melting, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. The welding process has a long history, but with the continuous advancement of science and technology, new welding technologies such as gas flame, arc, laser, electron beam, friction and ultrasonic welding technologies are also developing rapidly. However, traditional heat welding is still the first choice of various factories due to its low price.

[0003] When operators are performing welding operations on long-axis rods, they often use welding processing equipment to weld two long axis rods to meet the processing and use requirements of the materials. In actual use, although the existing processing equipment has basic welding functions, it can generally only clamp and fix long-axis rods of fixed sizes, resulting in the inability to meet the operators' needs for welding long-axis rods of different diameters, thereby reducing the applicability of the equipment, and therefore it needs to be improved.

[0020] 1. The utility model is provided with a mounting plate, a limit frame, a clamping claw, a push rod and a pneumatic cylinder. When the pneumatic cylinder is operated, the bottom end of the pull rod is pulled to the right. At this time, the upper end of the pull rod pulls the outer surface of the push ring so that the push ring starts to rotate under the limit of the limit plate.

When the No. 1 motor is running, the circular shaft drives the driving gear to rotate, and the driven wheel and the rotating plate start to rotate with the shaft insertion hole as the center under the drive of the driving gear. The operation of the No. 2 motor causes the lead screw to rotate. Due to the limiting of the limiting column, the moving plate moves downward as a whole, and finally the welding gun contacts the welding points of the two long shafts to be welded. Due to the rotation of the rotating plate, the welding gun circles around the welding points to achieve circumferential welding of the long shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] When the pushing ring 9 rotates, the inner surface of the pushing rod 7 is pushed and starts to rotate around the central column 8. During this process, the other end of the pushing rod 7 pushes the claw 6, causing the claw 6 to move toward the inner surface of the shaft insertion hole 24 and finally clamp the outer surface of the long shaft rod.

[0039] When the pneumatic cylinder 11 is running, the bottom end of the pull rod 12 will move to the right, and the upper end of the pull rod 12 will pull the outer surface of the push ring 9, which will cause the push ring 9 to start rotating under the limit of the limit plate 10.

[0040] A No. 1 motor 13 located outside the mounting plate 4 is fixedly mounted on the inner surface of the upper side of the mounting frame 2 , and a round shaft 14 is fixedly sleeved on the other end of the output shaft of the No. 1 motor 13 .

[0041] When the first motor 13 starts to run, the circular shaft 14 will rotate.

[0042] A driving gear 15 is fixedly sleeved on the outer surface of the circular shaft 14 , and a driven gear 16 is meshedly connected on the outer surface of the driving gear 15 .

[0043] When the circular shaft 14 starts to rotate, it will drive the driving gear 15 to rotate coaxially. At this time, the driven wheel 16 will rotate due to the meshing transmission of the driving gear 15.

[0044] The inner surface of the driven wheel 16 is fixedly connected to a rotating plate 17 , and the inner surface of the driven wheel 16 is fixedly connected to a connecting column 18 located below the rotating plate 17 .

[0049] Due to the function of the welding gun 23 , the welding gun 23 can weld the long shaft located below the welding gun 23 .

[0050] The working principle and use process of this utility model:

[0051] First, the operator inserts the two long shafts to be welded into the shaft insertion hole 24, and then starts the pneumatic cylinder 11. Due to the operation of the pneumatic cylinder 11, the bottom end of the pull rod 12 is pulled and starts to move to the right, and the upper end of the pull rod 12 will pull the push ring 9 to move. Due to the limitation of the limit plate 10, the push ring 9 will start to rotate around the shaft insertion hole 24, and the rotation of the push ring 9 will push the inner surface of the outer side of the push rod 7, which makes the push rod 7 start to rotate around the center column 8 as the axis. In this process, the other end of the push rod 7 will push the claw 6 to move the claw 6 toward the direction of the shaft insertion hole 24, and finally clamp the long shaft located inside the shaft insertion hole 24, thereby clamping long shafts of different diameters.

[0052] Then, the operator starts the No. 2 motor 19. The operation of the No. 2 motor 19 will cause the lead screw 20 to rotate. Due to the limitation of the limit column 21, the movable plate 22 will move downward along the axial direction of the limit column 21 as a whole, and finally the welding gun 23 will contact the welding points of the two long shafts to be welded. Then the operator starts the No. 1 motor 13. The operation of the No. 1 motor 13 will cause the circular shaft 14 to drive the driving gear 15 to rotate, and the driven wheel 16 and the rotating plate 17 will start to rotate around the shaft hole 24 as the center under the drive of the driving gear 15, which makes the welding gun 23 circle around the welding point and complete the circumferential welding of the two long shaft welds.
