Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, in particular to an efficient welding device. Background Technique

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials (such as plastics) by heating, high temperature or high pressure. During the processing of metal pipes, welding is often required to connect two or more metal pipes together to meet the usage requirements of different scenarios.

[0003] The utility model patent with the authorized announcement number CN218169293U discloses a steel pipe welding device, including a machine body. Four support legs are fixedly connected to the lower end of the machine body near the four corners. First chutes are respectively opened on both sides of the upper end surface of the machine body. First motors are fixedly arranged on one side inside each of the two first chutes. The output ends of the two first motors are fixedly connected with first threaded lead screws. First sliders are slidably sleeved on the outer walls of the two first threaded lead screws. First connecting blocks are fixedly connected to the upper end surfaces of the two first sliders. First clamping blocks are fixedly connected to the upper end surfaces of the two first connecting blocks. Second clamping blocks are fixedly arranged on both sides of the upper end surface of the machine body. A second chute is opened in the middle of one side of the machine body. In the utility model, this new type of steel pipe welding device has a good welding effect and can weld steel pipes of different sizes. At the same time, the welding device is movable.

[0004] After analysis, it is found that during the welding process of metal pipes or steel pipes, it is usually necessary to rotate the metal pipes or steel pipes to complete a whole welding process, so as to completely weld two metal pipes or steel pipes together. However, for the above-mentioned disclosed steel pipe welding device, although it can fix steel pipes of different sizes through the mutual cooperation of the first clamping block and the second clamping block, it is difficult to easily rotate the steel pipe after clamping. It can only be rotated after loosening the steel pipe, and then the steel pipe is clamped again, which greatly reduces the welding efficiency. Content of the Utility Model

Detailed Description of the Embodiment

[0026] The present utility model will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0027] As Figures 1 to 9 shown, the present utility model provides an efficient welding device, which includes an operating table 1 and a connecting frame 101 arranged on the side of the operating table 1. The end of the connecting frame 101 is connected with a welding head 103 through a cylinder 102. The operating table 1 is slidably connected with the connecting frame 101 through a lead screw 502. A second motor 5 is arranged on the upper surface of the operating table 1 to cooperate with the lead screw 502. The output end of the second motor 5 is connected with the lead screw 502 through a synchronous belt 501. The horizontal position of the welding head 103 can be controlled through the lead screw 502, and the height of the welding head 103 can be controlled through the cylinder 102. Two groups of fixing tables 2 are arranged opposite to each other on the surface of the operating table 1. The inside of the fixing table 2 is circularly hollow and is rotatably connected with a rotating tube 201. Worm gears 202 are arranged on the sides of the two rotating tubes 201 away from each other. A first motor 203 is arranged on the upper surface of the operating table 1 near the worm gear 202. The output end of the first motor 203 is provided with a worm 204, and the worm 204 meshes with the worm gear 202. During welding, the metal tube can be fixed by placing it inside the rotating tube 201. When the metal tube needs to be rotated during the welding process, only the two first motors 203 need to be started. It should be noted here that when the first motor 203 is started to control the rotation of the worm gear 202 through the worm 204 to drive the rotation of the rotating tube 201, the two rotating tubes 201 should rotate in the same direction. Three groups of T-shaped sliding grooves 104 are evenly spaced on the upper surface of the operating table 1. One group of T-shaped sliding grooves 104 is arranged in the middle position of the operating table 1 between the two fixing tables 2, and the two groups of T-shaped sliding grooves 104 are respectively arranged at both ends of the operating table 1. Each group of T-shaped sliding grooves 104 is slidably connected with a sliding table 105. The sliding table 105 is slidably connected with an arc-shaped plate 107 through a guide rod 106. A return spring 108 is arranged between the arc-shaped plate 107 and the sliding table 105. When the two ends of the metal tube to be welded are relatively long, the position of the sliding table 105 can be adjusted by sliding, and the arc-shaped plate 107 can be used to provide effective support for the metal tube.

[0028] As Figure 2 、 Figures 4 - 6 shown, driven wheels 3 are arranged on the sides of the two rotating tubes 201 close to each other. Four arc-shaped sliding grooves 301 are formed on the surface of the driven wheel 3. Four clamping plates 302 are slidably connected to the inside of the rotating tube 201 through sliding grooves. A push rod 303 is rotatably connected to the side of the clamping plate 302 close to the driven wheel 3, and the push rod 303 is slidably connected with the arc-shaped sliding groove 301. By rotating the driven wheel 3, the push rod 303 can be driven to move by the arc-shaped sliding groove 301. Under the action of the sliding groove inside the rotating tube 201, the clamping plate 302 is further driven to move, and the clamping of the metal tube can be completed.

[0029] As Figures 4 - 9 shown, a fixing plate 4 is connected to the side of the fixed table 2. The fixing plate 4 is rotatably connected with a driving wheel 401. A driving shaft 402 is slidably arranged inside the driving wheel 401. A flower shaft 403 is arranged at the end of the driving shaft 402. A first flower sleeve 404 is arranged on one side of the driving wheel 401 close to the fixing plate 4. The fixing plate 4 is provided with a second flower sleeve 405. The flower shaft 403 cooperates with the first flower sleeve 404 and the second flower sleeve 405. The length of the flower shaft 403 is equal to the length of the first flower sleeve 404 and greater than the length of the second flower sleeve 405. An annular limiting groove 406 is arranged inside the driving wheel 401. A stop block 407 is arranged on the side of the driving shaft 402 and is matched with the limiting groove 406. Under normal conditions, the flower shaft 403 at the end of the driving shaft 402 passes through the first flower sleeve 404 and is inserted into the second flower sleeve 405. At this time, since the fixing plate 4 is connected to the fixed table 2, the driving shaft 402 cannot be rotated at this time. Pull out the driving shaft 402 outward so that the end of the flower shaft 403 is separated from the second flower sleeve 405, and then the driving shaft 402 can be rotated, thereby driving the driving wheel 401 to rotate. A square opening 205 is arranged on the operation table 1 close to the driven wheel 3.

[0030] Specifically, before processing, first place the metal pipe through the rotating pipe 201, pull out the driving shaft 402 and then rotate the driving wheel 401 to control the rotation of the driven wheel 3 to clamp the metal pipe. During this process, the position of the arc-shaped plate 107 can be adjusted by sliding the sliding table 105 to better support the metal pipe. Then insert the driving shaft 402 inward to fix the driving wheel 401. Subsequently, control the movement of the welding head 103 to start welding. During the welding process, the first motor 203 can be started to drive the metal pipe to rotate, and the welding of the metal pipe can be completed at one time.

[0031] Based on the ideal embodiments of the present invention as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
