Description
Technical Field
[0001] This application relates to the field of welding technology, and in particular to a welding device for tee pipes. Background Technology
[0002] Tee pipes, as common pipe fittings, are widely used in petrochemical, power, and construction industries. Traditional tee pipe production primarily employs casting processes, but this process has many drawbacks. With the development of welding technology, welded tee pipes have gradually emerged. However, most existing welded tee pipe processing equipment suffers from low automation. Each process is independent, requiring frequent manual intervention for loading and unloading, and for transferring workpieces between different processes. This not only increases labor costs and reduces production efficiency but also easily leads to quality problems such as workpiece bumps and scratches during transfer, affecting product quality consistency.
[0003] Related prior art, such as Chinese patent application "An Automatic Welding and Automatic Locking Device for a T-shaped Steel Pipe", application number: CN202111224408.3, discloses a device including a base and a sliding welding part. The base includes a feeding hole, a pressure rod sliding hole, and a locking hole. The base is provided with a pressure locking device, which includes a pressure rod and a side rotating block. The pressure rod is slidably disposed in the pressure rod sliding hole, and its upper end extends beyond the upper plane of the base. It can slide downward when subjected to pressure. The side rotating block is rotatably disposed on the side of the pressure rod. A fourth elastic element is provided between the side rotating block and the pressure rod.
[0004] While some advanced tee pipe welding equipment has achieved a certain degree of automation, it's difficult to create completely universal welding equipment because the products being welded vary. Therefore, even with numerous welding machines available on the market, they still cannot meet the welding needs of different products. This application designs a new tee pipe welding machine specifically for tee pipe structures, meeting the welding requirements of products, improving production efficiency and welding quality, and offering ease of operation. Utility Model Content
[0005] The technical problem to be solved by this application is to provide a tee pipe welding device that enables stable fixing and flexible welding of tee pipes, thereby improving welding efficiency and quality.
[0006] The technical solution adopted in this application is as follows: a T-pipe welding equipment, including a frame, on which a moving device, a positioning fixture, a mounting base, and a pressing component are provided. The mounting base is rotatably mounted on the frame. The positioning fixture has a mounting slot adapted to the T-pipe. The mounting base is provided with a claw for fixing the positioning fixture. A pressing component is provided above the mounting base. When the pressing component is working, it acts on the T-pipe placed on the positioning fixture. The moving device is connected to a welding torch through an adapter plate assembly. When the moving device is working, it drives the adapter plate assembly and the welding torch to move. When the adapter plate assembly is working, it adjusts the pitch angle of the welding torch. The welding torch is set corresponding to the mounting base.
[0007] Compared with the prior art, the advantages of this application are as follows: First, the mounting base is rotatably mounted on the frame and is equipped with jaws for fixing the positioning fixture. The positioning fixture is provided with an installation slot adapted to the tee pipe. Together with the pressing component, the tee pipe is installed, ensuring that it is stably fixed on the positioning fixture during welding, preventing welding errors caused by tee pipe movement and improving welding quality. The tee pipe in this application is a semi-finished structure awaiting welding, and it has an inverted T-shaped structure on the positioning fixture.
[0008] Secondly, the moving device can drive the welding torch to move through the adapter plate assembly. At the same time, the adapter plate assembly can adjust the pitch angle of the welding torch, so that the welding torch can be flexibly adjusted according to the needs of different welding positions and angles, accurately corresponding to the tee pipe on the positioning fixture, realizing comprehensive and accurate welding of each weld seam of the tee pipe, and improving the flexibility and adaptability of welding.
[0009] Finally, all components of the equipment work together, using the mounting base for fixation, the pressure component for auxiliary fixation, the moving device and the adapter plate group to drive the welding torch for automated welding operations, thereby achieving an automated process for T-pipe welding and improving the production efficiency of T-pipe welding.
[0010] In some embodiments of this application, the mounting base has a disc-shaped structure, and the surface of the mounting base is provided with multiple mounting channels. One end of the multiple mounting channels is connected, and the other end of the mounting channels penetrates through the outer peripheral surface of the mounting base.
[0011] In some embodiments of this application, the installation channel is provided with a claw, the claw is connected to a driving component, the driving component applies a force to the claw to retract along the installation channel, the bottom of the positioning fixture is embedded in the mounting base and held and fixed by the claw, the top surface of the positioning fixture is provided with a V-shaped groove, the main pipe of the tee is placed in the V-shaped groove, and the branch pipe of the tee is set vertically upward.
[0012] The jaw-connecting drive unit can precisely control the jaws to retract or extend outward along the installation channel according to the size of the tee pipe, achieving a firm clamping or quick release of the tee pipe, thus improving the efficiency of tee pipe installation and disassembly. Simultaneously, the stepped outer circumference design of the jaws allows their tops to extend into the product and abut against the inner wall, enhancing the stability of the tee pipe fixation and ensuring accurate positioning and no deformation of the tee pipe during welding.
[0013] In some embodiments of this application, the mounting base is connected to the frame via a 90° worm gear reducer. Connecting the mounting base to the frame via the 90° worm gear reducer allows for smooth rotation of the mounting base, meeting the requirements of different angles during welding. Simultaneously, this connection method cleverly places the driving force on the frame, allowing the motor driving the rotation to be horizontally positioned, effectively reducing the height of the mounting base. This results in a more rational and compact overall equipment layout, lowers the equipment's center of gravity, and improves the stability of equipment operation.
[0014] In some embodiments of this application, the pressing assembly includes a column, a mounting plate, a pressing power cylinder, and a pressing component. The column is vertically mounted on the frame, the mounting plate is fixed to the column, and the pressing power cylinder is mounted on the mounting plate. This structural design improves the overall stability of the pressing assembly, and the pressing power cylinder can accurately press and fix the tee pipe on the positioning fixture, thus improving the stability of the tee pipe during the welding process.
[0015] In some embodiments of this application, the pressure member is cylindrical in shape, connected to a pressing power cylinder, and located directly above the mounting base. The pressure member and the mounting base are coaxially aligned, and the bottom surface of the pressure member is conical. When the pressure member is pressed down, it can accurately align with the tee pipe on the positioning fixture, and the conical bottom surface can simultaneously center the tee pipe, ensuring uniform force on the tee pipe during pressing. This further improves the stability of the tee pipe fixation and prevents errors caused by tee pipe wobbling during welding.
[0016] In some embodiments of this application, the mounting base has a circular groove at its center, and one end of multiple mounting channels is connected at the circular groove. The retracted claws have their inner ends retracted into the groove. The pressure member is coaxially arranged with the circular groove, and the outer diameter of the pressure member is adapted to the inner diameter of the circular groove. The retracted claws retracting into the groove do not affect the placement and installation of the tee pipe.
[0017] In some embodiments of this application, the mobile device includes an X-mobile component, a Y-mobile component, and a Z-mobile component. The X-mobile component is mounted on a frame, the Y-mobile component is mounted on the X-mobile component, the Z-mobile component is mounted on the Y-mobile component, and the adapter board assembly is mounted on the Z-mobile component.
[0018] The mobile device includes independent X, Y, and Z movement components, enabling precise movement of the welding torch in three-dimensional space to meet welding requirements at different positions and angles. This improves the flexibility and versatility of the equipment and allows for omnidirectional welding operations on complex tee pipe structures.
[0019] In some embodiments of this application, the adapter plate assembly includes a first plate and a second plate arranged parallel to each other, connected by a pivot. The first plate is connected to the Z-movement component, and the second plate is connected to the welding torch. This structural design allows for convenient adjustment of the welding torch's pitch angle, enabling rapid adjustment according to different welding positions and angles. This improves welding flexibility and adaptability, ensures the welding torch is always in the optimal welding position, and enhances welding quality and efficiency.

[0026] The present application will now be described in detail with reference to the accompanying drawings.
[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0028] A tee pipe welding device, as described in Embodiment 1 Figure 1 , Figure 2 As shown: The device includes a frame 1, on which a moving device 2, a positioning fixture 21, a mounting base 3, and a pressing assembly 4 are mounted. The mounting base 3 is rotatably mounted on the frame 1. The positioning fixture 21 has a mounting slot 22 adapted to the T-shaped pipe 23. The mounting base 3 is provided with a claw 6 for fixing the positioning fixture 21. The positioning fixture 21, with its mounting slot 22 adapted to the T-shaped pipe 23, works in conjunction with the pressing assembly 4 to install the T-shaped pipe 23. This ensures the T-shaped pipe 23 is stably fixed to the positioning fixture 21 during welding, preventing welding errors caused by movement of the T-shaped pipe 23 and improving welding quality. In this application, the T-shaped pipe 23 is a semi-finished structure awaiting welding, and it has an inverted T-shaped structure on the positioning fixture 21.
[0029] A pressing component 4 is disposed above the mounting base 3. When the pressing component 4 operates, it acts on the tee pipe 23 mounted on the positioning fixture 21. A welding torch 8 is connected to the moving device 2 via an adapter plate assembly 7. The moving device 2 moves the adapter plate assembly 7 and the welding torch 8. The adapter plate assembly 7 adjusts the pitch angle of the welding torch 8, which is positioned corresponding to the mounting base 3. The moving device 2 can move the welding torch 8 via the adapter plate assembly 7, which also adjusts the pitch angle of the welding torch 8. This allows the welding torch 8 to be flexibly adjusted according to different welding positions and angles, precisely corresponding to the tee pipe 23 on the positioning fixture 21. This enables comprehensive and accurate welding of all weld seams on the tee pipe 23, improving the flexibility and adaptability of the welding process.
[0030] The various components of this application work together to achieve an automated welding process for the welding of the tee pipe 23 through the fixing of the mounting base 3, the auxiliary fixing of the pressing component 4, the moving device 2, and the adapter plate group 7 driving the welding gun 8, thereby improving the production efficiency of welding the tee pipe 23.
[0031] Implement Column 2, such as Figures 1 to 3 As shown, the mounting base 3 has a disc-shaped structure, and the surface of the mounting base 3 is provided with multiple mounting channels 5. One end of the multiple mounting channels 5 is connected, and the other end of the mounting channels 5 penetrates through the outer peripheral surface of the mounting base 3.
[0032] Each mounting channel 5 is equipped with a claw 6, which is connected to a driving component. The driving component applies a force to the claw 6 to retract along the mounting channel 5. The bottom of the positioning fixture 21 is embedded in the mounting base 3 and held and fixed by the claw 6. The top surface of the positioning fixture 21 has a V-shaped groove, in which the main pipe of the tee pipe 23 is placed, and the branch pipes of the tee pipe 23 are vertically upward. The claw 6 is connected to the driving component, which can precisely control the claw 6 to retract or push outward along the mounting channel 5 according to the size of the tee pipe 23, thereby achieving a firm clamping or quick release of the tee pipe 23 and improving the efficiency of tee pipe 23 installation and disassembly. At the same time, the stepped outer peripheral surface design of the claw 6 allows its top to extend into the product and abut against the inner wall, enhancing the stability of fixing the tee pipe 23 and ensuring that the tee pipe 23 is accurately positioned and does not deform during welding.
[0033] The mounting base 3 is connected to the frame 1 via a 90° worm gear reducer 9. This connection allows for smooth rotation of the mounting base 3, meeting the requirements of different angles during welding. Simultaneously, this connection method cleverly places the driving force on the frame 1, allowing the motor driving the rotation to be horizontally positioned, effectively lowering the height of the mounting base 3. This results in a more rational and compact overall equipment layout, lowers the center of gravity, and improves the stability of equipment operation.
[0034] The pressing assembly 4 includes a column 11, a mounting plate 12, a pressing power cylinder 13, and a pressing component 14. The column 11 is vertically mounted on the frame 1, the mounting plate 12 is fixed to the column 11, and the pressing power cylinder 13 is mounted on the mounting plate 12. This structural design improves the overall stability of the pressing assembly 4, and the pressing power cylinder 13 can accurately press and fix the T-shaped pipe 23 on the positioning fixture 21, thus improving the stability of the T-shaped pipe 23 during the welding process.
[0035] The pressing component 14 has an overall cylindrical structure and is connected to the pressing power cylinder 13. The pressing component 14 is located directly above the mounting base 3 and is coaxially arranged with the mounting base 3. The bottom surface of the pressing component 14 has a conical structure. When the pressing component 14 is pressed down, it can accurately align with the T-shaped pipe 23 on the positioning fixture 21. Furthermore, the conical bottom surface can center the T-shaped pipe 23 while pressing down, ensuring that the T-shaped pipe 23 is subjected to uniform force during pressing. This further improves the stability of the T-shaped pipe 23 and prevents errors caused by the shaking of the T-shaped pipe 23 during welding.
[0036] The mounting base 3 has a circular groove at its center, and one end of multiple mounting channels 5 is connected at the circular groove. The retracted claw 6 has its inner end retracted into the groove. The pressure member 14 is coaxially arranged with the circular groove, and the outer diameter of the pressure member 14 is adapted to the inner diameter of the circular groove. The retracted claw 6 has its inner end retracted into the groove, which does not affect the placement and installation of the tee pipe 23.
[0037] The rest of the contents of Example 2 are the same as those of Example 1.
[0038] Example 3, as Figures 1 to 3 As shown, the moving device 2 includes an X-moving component 15, a Y-moving component 16, and a Z-moving component 17. The X-moving component 15 is mounted on the frame 1, the Y-moving component 16 is mounted on the X-moving component 15, the Z-moving component 17 is mounted on the Y-moving component 16, and the adapter plate assembly 7 is mounted on the Z-moving component 17. The moving device 2 includes independent X, Y, and Z-moving components 17, enabling precise movement of the welding torch 8 in three-dimensional space, meeting welding requirements at different positions and angles, improving the flexibility and versatility of the equipment, and enabling omnidirectional welding operations on complex tee pipe 23 structures.
[0039] The adapter plate assembly 7 includes a first plate 18 and a second plate 19 arranged parallel to each other. The first plate 18 and the second plate 19 are connected by a rotating shaft 20. The first plate 18 is connected to the Z-movement assembly 17, and the second plate 19 is connected to the welding torch 8. This structural design allows for convenient adjustment of the pitch angle of the welding torch 8, enabling it to be quickly adjusted according to different welding positions and angles. This improves the flexibility and adaptability of welding, ensures that the welding torch 8 is always in the optimal welding position, and enhances welding quality and efficiency.
