Abstract
Description
Technical Field
[0001] The present invention relates to the field of pipe fitting welding, and particularly to a pipe fitting welding device. Background Art
[0002] Welding, also known as fusion welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. In the process of welding pipe fittings, the common pipe fitting welding method is that workers hold a welding torch and place two pipe fittings on a support table for rolling spot welding. During the welding process, the two pipe fittings need to be on the same horizontal plane to complete butt welding. Since the pipe fitting placement area on the support table is a fixed structure and cannot perform lifting operations according to welding requirements, the spot welding position is prone to deviation, resulting in flaws easily appearing at the welded joints, affecting the welding quality and aesthetics. Summary of the Invention
[0003] In view of the above situation, in order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a pipe fitting welding device, and the advantages thereof solve the problems raised in the above background art.
[0004] The above technical object of the present invention is achieved through the following technical solutions: A pipe fitting welding device includes a base. On the top of the base, symmetric first sliding grooves and second sliding grooves are opened. A first sliding rail is slidably fitted in the first sliding groove. A bracket is vertically and fixedly connected to the first sliding rail. A laser welding torch is provided on the bracket. An electric control box is provided on one side of the bracket and is connected to the laser welding torch and the first sliding rail for control. A second sliding rail is slidably fitted in the second sliding groove. Symmetric supports are vertically and fixedly connected to the second sliding rail. Support plates are provided on the supports. Lifting components for driving the support plates to move up and down are provided on the tops of the supports. The lifting components include fixed seats arranged on both sides of the top of the support. A positive and negative thread screw rod is rotatably connected between the fixed seats. One end of the positive and negative thread screw rod extends outside the fixed seat. A rocker is fixedly connected to the extended end of the positive and negative thread screw rod. A first slider and a second slider are matched and connected to the outside of the positive and negative thread screw rod. Fixed blocks are fixedly connected to the tops of the first slider and the second slider. Support rods are rotatably connected to the fixed blocks. The tops of the support rods are hinged to bases. The bases are fixedly connected to the bottoms of the support plates. A welding pipe is placed between the tops of the support plates. Limiting components are also provided on both sides of the welding pipe. A machine tool body is provided on the surface of the top of the base on one side of the second sliding groove. A mounting disk is installed on the machine tool body on one side of the second sliding groove. A three-jaw chuck is provided on the side of the mounting disk away from the machine tool body. A connecting pipe is connected inside the three-jaw chuck.
[0005] By adopting the above technical solution, during the welding operation, the operator matches and connects the connecting pipe with the three-jaw chuck. Then, the operator places the welding pipe that matches the size of the connecting pipe between the tops of the support plates. The setting of the limiting component prevents the welding pipe from slipping. At this time, the operator simultaneously turns the rocker by hand according to the operation requirements, driving the rotation of the left and right hand thread screw rod. At this time, the first slider and the second slider on the left and right hand thread screw rod move towards each other in cooperation, and cooperate with the support rod and the base to lift the support plate up and down to a suitable height until the welding pipe on the support plate and the connecting pipe are at the same horizontal height. Then, the operator pushes the second slide rail, and horizontally moves it to the connecting pipe in cooperation with the support and other components on the support until the weld joints of the welding pipe and the connecting pipe are in contact. Then, the operator turns on the electric control box, and cooperates to control the horizontal movement of the first slide rail and the laser welding gun on the first slide rail to the welding position for welding work. During the welding work process, the operator turns on the machine body to drive the rotation of the mounting plate and the three-jaw chuck on the mounting plate. At this time, the connecting pipe and the welding pipe on the three-jaw chuck are driven to rotate synchronously and uniformly, and cooperate with the laser welding gun to complete the welding task.
[0006] Further setting: A support component is also provided between the support and the support plate. The support component includes telescopic rods arranged around the top of the support. The tops of the telescopic rods are fixedly connected with fixing plates, and the fixing plates are fixedly connected with the peripheries of the bottoms of the support plates.
[0007] By adopting the above technical solution, during the process of the support plate lifting up and down in cooperation with the lifting component, through the cooperation of a plurality of damping rods and springs arranged between the support and the support plate, it plays a certain role in support and stability.
[0008] Further setting: The limiting component includes fixing frames arranged on both sides of the top of the support plate, and limiting roller shafts are rotatably connected inside the fixing frames.
[0009] By adopting the above technical solution, when the operator places the welding pipe between the tops of the support plates, at this time, the limiting roller shafts on the fixing frames on both sides of the top of the support plate are in contact with the surface of the welding pipe, playing a certain limiting role to prevent slipping and affecting the welding work. At the same time, during the welding process, the welding pipe rotates in cooperation with the rotating shaft, playing a certain role in support and stability, and indirectly improving the welding operation efficiency.
[0010] Further setting: Rubber blocks are fixedly connected to the outer sides of the limiting roller shafts.
[0011] By adopting the above technical solution, when the surface of the welding pipe contacts the roller shaft, the rubber blocks arranged on the outer side of the roller shaft play a certain protective role to avoid damaging the surface of the welding pipe.
[0012] Further setting: A protective pad is fixedly connected to the outer side of the rocker.
[0013] By adopting the above technical solution, during the operation of the operator turning the hand crank rocker, the protective pad is in contact with the operator's hand, playing a certain protective role for the operator's hand and improving comfort.
[0014] Further setting: A plurality of extension plates are fixedly connected to the outer side of the base, and mounting bolts are threadedly connected to the plurality of extension plates.
[0015] By adopting the above technical solution, the setting of the extension plate and the mounting bolt facilitates the operator to fixedly install the entire device.
[0016] In summary, the present invention has the following beneficial effects: During the welding operation of the present invention, the operator matches and connects the connecting pipe with the three-jaw chuck. Then, the operator places the welding pipe matching the size of the connecting pipe between the tops of the support plates. The setting of the limiting component prevents the welding pipe from slipping. At this time, the operator turns the hand crank rocker according to the operation requirements, driving the rotation of the left and right-handed screw rod. At this time, the first slider and the second slider on the left and right-handed screw rod move towards each other in cooperation, and cooperate with the support rod and the base to lift the support plate up and down to a suitable height until the welding pipe on the support plate and the connecting pipe are at the same horizontal height, avoiding the deviation of the welding point position and indirectly improving the welding operation efficiency.
