Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe rotation processing, in particular to a pipe rotation device for laser welding. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is a heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts. Tube rotation refers to circular motion around a point or axis.

[0003] The existing laser welding tube rotation requires the user to check and screen the tubes during processing, to check whether there are any defects or unqualified products in the production process and to remove them. Laser welding technology is required in the tube processing process. If the tube tilts during the welding process, the tube will be unqualified, which will lead to a high unqualified rate of the tubes, which not only leads to a waste of manpower and material resources, but also affects the production efficiency of the enterprise. Often, when processing the tubes, the user needs to hold one end of the tube by hand to keep it stable during the rotation welding process and prevent it from tilting, so as to reduce the deviation in the tube processing process. However, this method is suitable for processing a small number of tubes. When a large number of tubes are produced, it may be necessary to increase manpower. Therefore, a laser welding tube rotation device is proposed. Utility Model Content

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.

[0021] like Figures 1 to 5 As shown, the utility model provides a tube rotating device for laser welding, including a base 1, a welding machine body 2 is installed on the top of the base 1, a connecting block 3 is arranged on the top of the base 1, a rack 4 is installed on the top of the connecting block 3, a clamping plate 5 is installed on the outside of the rack 4, a gear 6 is meshed on the outside of the rack 4, a rotating shaft 8 is sleeved inside the gear 6, a round wheel 7 is installed on the top of the rotating shaft 8, a belt 9 is sleeved inside the rotating shaft 8, a spring 12 is installed outside the belt 9, a pipe fitting 10 is arranged on the top of the base 1, and a forward and reverse motor 11 is installed on the bottom of the rotating shaft 8.

[0022] The above scheme is adopted: the user places the belt 9 on the fixed frame, starts the forward and reverse motors 11 to drive the rotating shaft 8 to rotate, and drives the external sleeve gear 6 to rotate through the rotating shaft 8, so that the two adjacent racks 4 are brought closer to the middle along the outside of the gear 6, and at the same time drives the connecting block 3 to move along the rectangular groove opened on the top of the base 1, and drives the two adjacent clamping plates 5 to move closer to the middle through the two adjacent racks 4 so that the clamping plates 5 contact the pipe 10, and fix the pipe 10 through the clamping plates 5. At this time, the user puts the pipe 10 in the belt 9, so that the pipe 10 contacts the spring 12 installed on the outside of the belt 9, and squeezes the spring 12 according to the size of the pipe 10, so that the spring 12 fits the pipe 10. At this time, the gear 6 moves forward along the rotating shaft 8, and drives the belt 9 when the rotating shaft 8 rotates. At the same time, the belt 9 drives the pipe 10 to rotate. After the user turns on the laser welding equipment and adjusts the height of the welding gun head, the pipe 10 can be processed and welded. In this process, the processing speed of the belt 9 is improved, and the situation that the belt 9 is prone to tilting during the processing is reduced.

[0023] like Figure 1 and Figure 2As shown, a rectangular groove is provided on the top of the base 1, and two adjacent connecting blocks 3 slide horizontally in the rectangular groove; one end of the clamping plate 5 is in a "C" shape, and the clamping plate 5 contacts the pipe 10 when moving; the rotating shaft 8 is in a "X" shape, and a circular groove is provided on the outside of the round wheel 7, and the outside of the circular groove is connected with the belt 9.

[0024] The above scheme is adopted: by starting the forward and reverse motors 11 to drive the rotating shaft 8 to rotate, and at the same time the rotating shaft 8 drives the gear 6 to rotate, and the gear 6 drives the two adjacent racks 4 to move toward the middle and get closer to each other, and the rack 4 drives the connecting block 3 and the clamping plate 5 to get closer to the middle, so that the clamping plate 5 contacts and fixes the pipe 10, and the spring 12 arranged on the outside of the round wheel 7 squeezes the pipe 10 according to the different sizes to make it fit with the pipe 10. At this time, the gear 6 moves forward along the special shape of the rotating shaft 8, disengages from the two adjacent racks 4, drives the pipe 10 to rotate through the round wheel 7, and can be processed by laser welding equipment. In this process, the stability of the pipe 10 during processing is improved.

[0025] like Figure 1 and Figure 3 As shown, a control box is provided on one side of the welding machine body 2, and a telescopic rod is installed at the bottom of the control box; a fixing frame is provided on the outside of the pipe fitting 10, and the fixing frame is installed on the top of the base 1; one end of the spring 12 is connected to the outside of the belt 9, and a rectangular plate is provided on the other end, and the rectangular plate is in contact with the pipe fitting 10.

[0026] The above scheme is adopted: the height of the laser welding gun head is adjusted by the equipment outside the welding machine body 2 to process the pipe fitting 10, and the fixing frame installed on the top of the pipe fitting 10 is used to fix the pipe fitting 10 when it shakes during the processing. Because the pipe fittings 10 are of different sizes, the spring 12 arranged on the outside of the belt 9 is squeezed when the pipe fitting 10 enters to make it fit with the pipe fitting 10. In this process, the stability of the pipe fitting 10 is improved and the probability of tilting of the pipe fitting 10 during processing is reduced.

[0027] The working principle and use process of this utility model:

[0028] First, the user transports the belt 9 that meets the conditions through the equipment to the laser welding equipment, picks up the belt 9 and places it on the fixed frame, starts the forward and reverse motor 11 to drive the shaft 8 to rotate, and drives the external sleeve gear 6 to rotate through the shaft 8, so that the two adjacent racks 4 move toward the middle along the outside of the gear 6, and at the same time drives the connecting block 3 to move along the rectangular groove opened on the top of the base 1, and drives the two adjacent clamping plates 5 to move toward the middle through the two adjacent racks 4 so that the clamping plates 5 contact the pipe 10, and fix the pipe 10 through the clamping plates 5. At this time, the user puts the pipe 10 in the belt 9 so that the pipe 10 and the outside of the belt 9 are connected. The installed spring 12 contacts the pipe 10, and the spring 12 is squeezed by the size of the pipe 10 to make the spring 12 fit the pipe 10. When the two adjacent clamps 5 fix the pipe 10, the gear 6 moves forward along the rotating shaft 8, so that the gear 6 does not contact the rack 4 and does not affect the fixation of the pipe 10 by the clamp 5. When the rotating shaft 8 rotates, the belt 9 is driven, and the belt 9 drives the pipe 10 to rotate. After the user turns on the laser welding equipment and adjusts the height of the welding gun head, the pipe 10 can be processed and welded so that it will not tilt during the rotation process. In this process, the processing efficiency of the pipe 10 is improved and the waste of manpower and material resources is reduced.
