Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, and more specifically, to a steel pipe welding machine. Background Technology

[0002] A welding machine is a device that welds multiple metal parts together. Since steel pipes are circular, welding two steel pipes requires circumferential welding around the pipe. Currently, steel pipe welding is mostly done manually by rotating the steel pipe. Manual rotation results in uneven speed, poor welding quality, and low work efficiency because workers need to rotate the pipe while welding. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a steel pipe welding machine, which aims to improve the current steel pipe welding process, which mostly involves manually rotating the steel pipe for circumferential welding. This results in uneven rotation speed, poor welding quality, and low work efficiency as workers need to rotate the pipe while welding.

[0004] This utility model is implemented as follows: This utility model provides a steel pipe welding machine, including an installation component and a rotating component. The rotating component is disposed on the installation component, and the rotating component realizes automatic uniform rotation of the steel pipe to be welded.

[0005] The mounting assembly includes a base, a mounting bracket, a cross arm, a welding head, a first support body, and a second support body. The mounting bracket is fixedly mounted on the base, the cross arm is disposed on the mounting bracket, the welding head is mounted on the cross arm, the first support body is fixedly mounted on the base, and the second support body is disposed on the base. Both the first support body and the second support body are provided with chucks.

[0006] The rotating assembly includes a first motor, a first gear, a second gear, a first sleeve, and a first rotating body. The first motor is fixedly mounted on the base, the first gear is fixedly mounted on the output shaft of the first motor, the second gear meshes with the first gear, the second gear is fixedly mounted on the first sleeve, and the first rotating body is fixedly mounted on one end of the first sleeve and rotatably mounted on the first support.

[0007] In one embodiment of the present invention, a pushing assembly is further included. The pushing assembly includes a first mounting plate, a driving component, and a moving plate. The first mounting plate is fixedly mounted on one side of the base, the driving component is fixedly mounted on the first mounting plate, the moving plate is fixedly mounted on the output end of the driving component, and the second support is fixedly mounted on the moving plate.

[0008] In one embodiment of the present invention, a second rotating body is rotatably mounted on the top end of the second support body, and a second sleeve is fixedly mounted on one end of the second rotating body.

[0009] In one embodiment of this utility model, a slider is fixedly installed at the bottom end of the movable plate, the slider is slidably connected to a guide rail, and the guide rail is fixedly installed on the base.

[0010] In one embodiment of this utility model, a protective cover is fixedly installed on one side of both the first support and the second support.

[0011] In one embodiment of this utility model, the lifting assembly includes a second mounting plate, a second motor, and a lead screw. The second mounting plate is fixedly installed inside the mounting frame, the second motor is fixedly installed on the second mounting plate, one end of the lead screw is fixedly installed on the output shaft of the second motor, and the other end is rotatably installed on the top of the mounting frame. The cross arm is connected to the lead screw via a transmission.

[0012] In one embodiment of this utility model, a positioning component is further included. The positioning component includes a positioning frame and a positioning plate. The positioning frame is fixedly installed on the positioning plate, and the positioning plate can be closely attached to the chuck.

[0013] The beneficial effects of this utility model are as follows: When using the steel pipe welding machine obtained by the above design, a steel pipe is inserted into the inside of the first sleeve so that it passes through the first rotating body and then passes out from the center of the chuck. Then the positioning plate and the plane of the chuck on the first rotating body are pressed together, and then the end of the steel pipe and the front part of the positioning frame are made to abut against each other, thereby realizing the positioning of the first steel pipe. Then the chuck is started and the chuck clamps the steel pipe.

[0014] Then, another steel pipe is inserted from the outside of the second sleeve, passing through the second rotating body. The steel pipe then exits through the center of the chuck mounted on the second rotating body, and continues to be pushed forward until the front section of the steel pipe contacts the steel pipe on the first rotating body. Then, the chuck on the second rotating body is activated, clamping the steel pipe. Then, the first motor is started, driving the first gear to rotate, which in turn drives the second gear to rotate. The second gear then drives the first sleeve to rotate, which in turn drives the first rotating body to rotate. The first rotating body, through the chuck, drives the first steel pipe to rotate. Since the first and second steel pipes are pressed and abutted together, the rotation of the first steel pipe simultaneously drives the rotation of the second steel pipe, thus achieving simultaneous rotation of both steel pipes. This allows the welding head to perform circumferential welding of the two steel pipes. The above device achieves automatic uniform rotation of the two steel pipes to be welded, resulting in high welding quality and high work efficiency without the need for manual rotation of the steel pipes.

[0024] Please see Figure 1-6 A steel pipe welding machine includes an installation component 100 and a rotating component 200. The rotating component 200 is mounted on the installation component 100 and realizes automatic uniform rotation of the steel pipe to be welded.

[0025] Please see Figure 1-5 The mounting assembly 100 includes a base 110, a mounting bracket 120, a cross arm 130, a welding head 140, a first support body 150, and a second support body 160. The mounting bracket 120 is bolted to the middle of the base 110. The cross arm 130 is mounted on the mounting bracket 120. The welding head 140 is bolted to the end of the cross arm 130 away from the mounting bracket 120. The first support body 150 is bolted to one side of the base 110. The second support body 160 is mounted on the base 110. Each of the 60 components is equipped with a chuck, which can be a hydraulic chuck. Specifically, a second rotating body 161 is rotatably mounted on the top of the second support body 160, and a second sleeve 162 is fixedly mounted on one end of the second rotating body 161. A chuck is fixed on the second rotating body 161. Specifically, a slider 331 is fixedly mounted on the bottom of the moving plate 330 by bolts. The slider 331 is slidably connected to a guide rail 332, and the guide rail 332 is fixedly mounted on the base 110 by bolts, thereby guiding the moving plate 330 during movement, reducing friction, and saving energy.

[0026] Please see Figure 2 and Figure 4 The rotating assembly 200 includes a first motor 210, a first gear 220, a second gear 230, a first sleeve 240, and a first rotating body 250. The first motor 210 is fixedly mounted on the base 110 by bolts. The first gear 220 is fixedly mounted on the output shaft of the first motor 210 by a key. The second gear 230 meshes with the first gear 220 and is fixedly mounted on the first sleeve 240 by a key. The first rotating body 250 is fixedly mounted on one end of the first sleeve 240 by welding. The first rotating body 250 is rotatably mounted on the first support body 150. A chuck is fixedly mounted on the first rotating body 250, and the chuck is the same size and model as the chuck on the second rotating body 161, and their axis centers are at the same height. In this way, after the two chucks clamp the steel pipes, the axis centers of the two steel pipes are also at the same height, realizing the alignment of the two steel pipes.

[0027] Please see Figure 2 and Figure 3It should be noted that a protective cover 170 is fixedly installed on one side of the first support body 150 and the second support body 160. The first motor 210, the first gear 220 and the second gear 230 are all set inside the protective cover 170 to achieve isolation and protection. At the same time, the protective cover 170 supports the first sleeve 240 and the second sleeve 162, improving the stability of the first sleeve 240 and the second sleeve 162 when they rotate.

[0028] Please see Figure 4 and Figure 5 In one embodiment of this utility model, a pushing assembly 300 is also included. The pushing assembly 300 includes a first mounting plate 310, a driving component 320, and a moving plate 330. The first mounting plate 310 is fixedly mounted to one side of the base 110 by bolts. The driving component 320 is fixedly mounted to the first mounting plate 310. The driving component 320 can be a cylinder or an electric push rod. The moving plate 330 is fixedly mounted to the output end of the driving component 320. The second support body 160 is fixedly mounted to the moving plate 330 by bolts, so as to realize the movement of the second support body 160, thereby enabling the two steel pipes to be tightly pressed together by extrusion force, thereby realizing the simultaneous rotation of the two steel pipes.

[0029] Please see Figure 2 and Figure 3 In one embodiment of this utility model, the lifting assembly 400 includes a second mounting plate 410, a second motor 420, and a lead screw 430. The second mounting plate 410 is fixedly installed inside the mounting frame 120 by bolts. The second motor 420 is fixedly installed on the second mounting plate 410 by bolts. One end of the lead screw 430 is fixedly installed on the output shaft end of the second motor 420 by a coupling, and the other end is rotatably installed on the top of the mounting frame 120 by a bearing. The cross arm 130 is threadedly connected to the lead screw 430 to realize the up and down movement of the cross arm 130, thereby realizing the lifting and lowering of the welding head 140, which facilitates welding.

[0030] Please see Figure 2 and Figure 6 In addition, it also includes a positioning component 500, which includes a positioning frame 510 and a positioning plate 520. The positioning frame 510 is fixedly installed on the positioning plate 520 by bolts. The positioning frame 510 has an L-shaped design. When the positioning plate 520 is close to the chuck to install the first steel pipe, the plane of the positioning plate 520 and the chuck on the first rotating body 250 are close together, and then the end of the steel pipe and the front part of the positioning frame 510 abut against each other, thereby realizing the positioning of the first steel pipe. Then the chuck is activated and the chuck clamps the steel pipe. When the positioning plate 520 abuts against the chuck surface, the end of the positioning frame 510 away from the positioning plate 520 is in the same vertical plane as the axis of the welding head, thereby realizing the positioning of the first steel pipe, so that its welding surface and the axis of the welding head are in the same vertical plane.

[0031] The working principle of the steel pipe welding machine is as follows: First, a steel pipe is inserted into the inside of the first sleeve 240, so that it passes through the first rotating body 250, and then passes out from the center of the chuck. Then, the positioning plate 520 and the plane of the chuck on the first rotating body 250 are pressed together, and then the end of the steel pipe is made to abut against the front of the positioning frame 510, thereby realizing the positioning of the first steel pipe. Then, the chuck is activated, and the chuck clamps the steel pipe.

[0032] Then insert another steel pipe from the outside of the second sleeve 162, the steel pipe passes through the second rotating body 161, and then the steel pipe passes out from the center of the chuck installed on the second rotating body 161. Then continue to push the steel pipe forward until the front part of the steel pipe contacts the steel pipe on the first rotating body 250. Then activate the chuck on the second rotating body 161, and then the chuck clamps the steel pipe.

[0033] Then the driving component 320 pushes the moving plate 330 forward, and the moving plate 330 drives the second support body 160 to move forward, and the second support body 160 drives the second rotating body 161 to move forward, and the second rotating body 161 drives the second steel pipe to move forward through the chuck, and the second steel pipe and the first steel pipe come into tight contact together.

[0034] Then the second motor 420 drives the lead screw 430 to rotate, and the lead screw 430 drives the cross arm 130 to move downward, and the cross arm 130 drives the welding head 140 to move downward until the distance between the welding head 140 and the steel pipe reaches the predetermined position and stops moving. Then the welding head 140 is opened first, and then the welding head 140 welds the connection between the two steel pipes.

[0035] Then the first motor 210 starts, which drives the first gear 220 to rotate, which in turn drives the second gear 230 to rotate, which in turn drives the first sleeve 240 to rotate, which in turn drives the first rotating body 250 to rotate, which in turn drives the first rotating body 250 to rotate via a chuck. Since the first and second steel pipes are pressed and pressed together, the rotation of the first steel pipe simultaneously drives the rotation of the second steel pipe, thus achieving simultaneous rotation of the two steel pipes. Consequently, the welding head 140 performs circumferential welding to connect the two steel pipes.

[0036] It should be noted that the specific models and specifications of the first motor 210, the drive component 320, and the second motor 420 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0037] The power supply and operating principle of the first motor 210, the drive unit 320, and the second motor 420 are clear to those skilled in the art and will not be described in detail here.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
