Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to equipment for sleeve welding joints. Background Art

[0002] Pipeline connections are often made by welding. During the production process, it is often necessary to weld a joint at the end of the pipe. Currently, manual welding is a common method for arc-shaped pipeline welding. The disadvantages of this welding method are: very low efficiency and uneven welds; and the weld joints of the pipe and the joint often do not fit together or the joints are offset. There may even be weld undercuts, weld bumps, and weld dew points, which can lead to cracks in the weld, affecting the service life of the pipeline or causing the pipeline weld to be defective and unable to be used normally. Utility Model Content

The outer wall of the sleeve is supported by a pair of driven wheels and is rollingly connected to the driven wheels.

[0007] Furthermore, the chuck is provided with a plurality of joint claws, which are arranged through a "T"-shaped slide groove on the chuck. The plurality of joint claws are evenly distributed on the chuck. When the joint is connected to the chuck, each joint claw is slid along the slide groove to fix the joint on the chuck.

[0008] Further, the welding torch includes a welding rod and a welding column. The welding torch head is arranged at one end of the welding rod in the horizontal direction, and the other end of the welding rod is connected to the welding column in the vertical direction. The welding rod and the welding column are connected by a connecting block, and the connecting block can slide on the welding column after connecting the welding rod. When the specification of the sleeve changes and causes the position of the weld seam to change, the position of the welding rod can be adjusted to align the welding torch head with the weld seam.

[0011] The beneficial effects of the present utility model are as follows: By arranging a sleeve rotating unit and a sleeve supporting unit on the equipment for the sleeve welding joint, the sleeve can rotate stably and evenly in the horizontal direction after being connected to the joint. At this time, the welding torch equipment arranged on one side of the base can weld the weld seam evenly.

[0012] The sleeve rotating unit can realize the uniform rotation of the joint through the motor, the transmission, the headstock and the main shaft. A plurality of slidable joint claws are arranged on the chuck. When the size of the joint changes, the different-sized joints can be fixed by sliding the joint claws, which is suitable for joints of various sizes.

[0013] A sliding plate is arranged on the sleeve supporting unit, and side strips are arranged at the bottom of the sliding plate.

[0027] Please refer to Figures 1 to 4

[0028] A device for welding the sleeve joint includes a base 1. On both sides of the upper surface of the base 1, a sleeve rotation unit and a sleeve support unit are respectively provided. One end of the sleeve 11 is placed on the sleeve support unit, and the other end of the sleeve 11 is connected to the connector 10 and then placed in the sleeve rotation unit. A welding torch is arranged on one side of the base 1, the welding torch 12 is arranged at the connection between the sleeve 11 and the connector 10, and a control cabinet 5 is arranged on the other side of the base 1. The control cabinet 5 is electrically connected to the motor 4 on the transmission 3 and the welding torch 12 respectively.

[0029] The sleeve rotation unit includes a headstock 2, a transmission 3 and a chuck 6. The headstock 2 is arranged on the base 1. A main shaft is arranged in the headstock 2. The main shaft penetrates through the headstock 2 and is connected to the transmission 3 at one end and the chuck 6 at the other end. The main shaft and the sleeve 11 are arranged on the same straight line. The transmission 3 is connected to the motor 4. When the motor 4 is started, the motor 4 drives the main shaft to rotate, thereby driving the chuck 6 to rotate;

[0030] The chuck 6 is cylindrical. One circular surface is connected to the main shaft, and the other circular surface is connected to the connector 10. Near one end of the surface connected to the connector 10, three connector claws 601 are respectively arranged along the circumferential direction. The connector claws 601 are arranged through the "T"-shaped slide grooves 602 at the corresponding positions on the chuck 6. The three connector claws 601 are evenly distributed on the chuck 6. When the connector 10 is connected to the chuck 6, each connector claw 601 slides along the slide groove 602 to fix the connector 10 on the chuck 6; [[ID=3,6]]

[0031] The casing support unit includes a sliding plate 7, a connecting plate 8 and a driven wheel 9. The bottom of the sliding plate 7 contacts the base 1. Both ends of the bottom of the sliding plate extend downward and protrude, presenting two side strips 701. The two side strips 701 cover both sides of the base 1 respectively. Two bolts 702 are provided on each side strip 701. During use, the sliding plate 7 is placed on the base 1. The placement position is determined by the length of the casing 11. The sliding plate 7 is fixed to the base 1 by screwing the bolts 702 on each side strip 701. When the casing 11 rotates with the joint 10, the sliding plate 7 can remain stable and is not easily overturned.

[0032] The connecting plate 8 is connected to the upper surface of the sliding plate 7. The top end of the connecting plate 8 has an arc-shaped groove 801. A pair of driven wheels 9 are respectively arranged at the upper end of the connecting plate and are located at both ends of the groove 801. The height of the driven wheels 9 is higher than that of the groove 801. One end of the casing 11 is placed above the groove 11. The outer wall of the casing 11 is supported by a pair of driven wheels 9 and is in rolling connection with the driven wheels 9. When the casing 11 rotates with the joint 10, the driven wheels 9 assist the casing 11 to rotate.

[0033] The welding torch 12 includes a welding rod 1201 and a welding column 1202. One end of the horizontally arranged welding rod 1201 is connected to the welding torch head, and the other end is connected to the vertically arranged welding column 1202 through a connecting block 1203. A fixing bolt is provided on the connecting block 1203. By opening the fixing bolt, the welding rod 1201 can slide on the welding column 1202. When the specifications of the casing 11 and the joint 10 change, resulting in a change in the weld position, the position of the welding rod 1201 can be adjusted to align the welding torch head with the weld.

[0034] In specific operations, one end of the joint 10 is inserted into the chuck 6. Through the "T"-shaped chute 602, three joint claws 601 slide to fix the joint 10 on the chuck 6. The other end of the joint 10 is connected to the casing 11. After the casing 11 is connected to the joint 10, its end is supported by the casing support unit. The control cabinet 5 is used to control the motor 4 to start. The motor 4 drives the main shaft to rotate and drives the chuck 6 to rotate. At this time, the end of the casing 11 also rotates accordingly. The driven wheels 9 assist the casing 11 to rotate. At the same time, the welding torch is started to weld the connection between the joint 10 and the casing 11.

[0035] The above has described a specific embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
