Description

Technical Field

[0001] This invention belongs to the field of mechanical parts processing technology, specifically a tee pipe clamping and welding device. Background Technology

[0002] Whether in urban residential water supply or industrial water supply, tees are an essential connecting component for pipe branching. Tees are generally made by welding. When welding a typical tee, the main pipe is clamped by a clamp, then the branch pipe is clamped and fixed and spliced ​​with the main pipe. Finally, the splice is welded and fixed by welding equipment.

[0003] A patent with publication number CN108000047B discloses a clamping device for thin-walled tee pipes used in welding. This device features an adjustable angle between the clamping arms of a V-shaped clamping mechanism, allowing it to clamp pipes within a certain size range and offering versatility. Rubber anti-slip pads on the inner sides of the clamping arms effectively increase friction, prevent slippage, and provide cushioning to avoid damaging the thin-walled pipe or its appearance. The hollow structure of the clamping arms increases rigidity and reduces weight, improving the overall stability of the mechanism. A guide rail is incorporated into the V-shaped clamping mechanism, enabling lateral sliding, adjustment, and fixation. A first sliding groove on the vertical slide rod allows for vertical sliding, adjustment, and positioning of the entire V-shaped clamping mechanism. A T-shaped slider corresponding to a T-shaped groove on the base plate is located at the bottom of the horizontal slide rod support frame, allowing the horizontal slide rod support frame to slide. This provides three degrees of freedom for the clamping device, enhancing its versatility.

[0004] The above-mentioned solution still has some problems in practical application. Usually, the pipe fitting is placed flat on the workbench and clamped and fixed using a clamping mechanism. Then, another pipe fitting is installed on the outside of the pipe fitting to form a tee fitting. At the same time, the laser welder is controlled to weld and fix the pipe fitting around the joint. However, the existing welding equipment has difficulty clamping and positioning the spliced ​​tee fitting when processing and manufacturing the tee fitting. At the same time, it is difficult to press the two pipe fittings together, making the gap at the joint of the two pipe fittings smaller. As a result, after welding and manufacturing the tee fitting, the gap at the joint of the two pipe fittings is large, which reduces the internal compressive strength of the finished tee fitting and results in low welded structural strength.

[0005] Therefore, the present invention provides a tee fitting clamping and welding device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0009] The cross-shaped push disk is externally connected to four push rods, and each push rod is rotatably connected to a fixed block at one end. A clamping plate is fixed to one end of the fixed block, which can drive the clamping plate to expand for squeezing and clamping the fixed pipe.

[0010] A robotic arm is installed on one side of the upper surface of the base, and a laser welder is installed at one end of the robotic arm. The robotic arm can drive the laser welder to weld the joint of the pipe fittings into a tee pipe.

[0011] The telescopic column is slidably connected to an H-shaped slide plate, and the H-shaped slide plate is rotatably connected to an L-shaped flip rod. The L-shaped flip rod is used to flip and clamp the pipe fittings, enabling the pipe fittings to be assembled into a T-shaped pipe.

[0012] Preferably, four limiting posts are fixedly connected to one side of the cross-shaped push disk, and the four limiting posts are slidably connected to the rotating post.

[0013] Preferably, the telescopic column is provided with a protrusion on its exterior, a cross-shaped abutment is fixedly connected to one end of the telescopic column, and an H-shaped slide plate is slidably connected between the protrusion and the cross-shaped abutment.

[0014] Preferably, a mounting groove is provided on one side of the rotating column, and an electric push rod is installed in the inner cavity of the mounting groove. The piston rod end of the electric push rod is fixedly connected to the telescopic column.

[0015] Preferably, the clamps are fixed to a U-shaped fixing frame at one end close to each other, and the L-shaped flipping rod is rotatably connected to the inner cavity of the U-shaped fixing frame.

[0016] Preferably, multiple sleeves are installed on the outside of the rotating column, and sliding columns are slidably connected to the inner cavities of the multiple sleeves, with the upper end of the sliding column being fixedly connected to the clamping plate.

[0017] Preferably, a storage groove is provided inside one end of the L-shaped flipping rod, and a T-shaped slide rod is slidably connected to the inner cavity of the storage groove. A tension spring is fixed to one end of the T-shaped slide rod, and one end of the tension spring is fixed to the inner wall of the storage groove. A clamping block is fixed to one end of the T-shaped slide rod.

[0018] Preferably, the upper end of the clamp is provided with a groove, a fixed slide rod is fixedly connected to the inner cavity of the groove, a stop block is slidably connected to the outside of the fixed slide rod, a first spring is fixedly connected to one side of the stop block, and one end of the first spring is fixedly connected to the inner wall of the groove.

[0019] Preferably, the inner cavity of the fixing frame is provided with a rotating groove, and the gear ring is rotatably connected in the inner cavity of the rotating groove.

[0020] Preferably, a servo motor is installed on one side of the fixed frame, and the output shaft end of the servo motor passes through the fixed frame and is fixedly connected to a gear in the inner cavity of the rotating groove. The gear meshes with the gear ring.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. The tee fitting clamping and welding equipment of the present invention, by driving the telescopic column to slide out of the rotating column and move the fixed plate to push the second spring to drive the cross-shaped pushing plate to move, and then push the clamping plate to expand and clamp the fitting. After the fitting is clamped and fixed, by continuously driving the telescopic column to move, the fixed plate is driven to squeeze the second spring to move. At the same time, the telescopic column uses the protrusion to push the H-shaped sliding plate to move, which in turn drives the L-shaped flipping rod to flip. At the same time, the L-shaped flipping rod abuts and clamps the inner wall of the fitting, so that the fitting is in contact with the outside of the rotating column. The pipe fittings are connected and tightly joined together. Then, a laser welder is used to weld the pipe fittings together. This solves the problem that if the existing tee pipe fitting welding settings are not spliced ​​together during the processing and manufacturing of tee pipe fittings, and the joints of the pipe fittings are not clamped and tightly fitted to reduce the gap at the joint, the gap at the joint will be too large when welding the pipe fittings together to manufacture the tee pipe. This will affect the structural strength of the manufactured tee pipe and cause the internal pressure that the tee pipe can withstand in the later stage to be insufficient.

[0023] 2. The tee fitting clamping and welding equipment of the present invention drives an L-shaped rotating rod to rotate, which in turn moves a T-shaped sliding rod. Simultaneously, the T-shaped sliding rod moves a clamping block, allowing the clamping block to abut against the inner wall of the fitting. With the continuous rotation of the L-shaped rotating rod, the clamping block pushes the inner wall of the fitting against the outer wall of the rotating rod to splice the fitting, thus reducing the gap between fittings. When butt welding pipes, the fitting is clamped and fixed using a clamping plate. Then, the L-shaped rotating rod drives the clamping block to clamp another fitting. Simultaneously, the L-shaped rotating rod drives the clamping block to rotate, clamping the fitting and pushing it against the fitting outside the clamping plate. This improves the practicality of the welding equipment, enabling it to clamp and connect different fittings during production and processing. It solves the problem that existing tee fitting welding equipment can only clamp and splice tee pipes, resulting in high equipment costs and difficulty in processing different types of fittings.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Example 1: As Figures 1 to 8As shown in the figure, a tee fitting clamping and welding device according to an embodiment of the present invention includes a base 1, a fixed frame 2 installed on one side of the upper end face of the base 1, a toothed ring 3 rotatably connected to the inner cavity of the fixed frame 2, a rotating column 4 fixedly connected to the inner cavity of the toothed ring 3, a telescopic column 32 slidably connected inside the rotating column 4, and an expansion clamping assembly provided outside the telescopic column 32.

[0036] Furthermore, the expansion clamping assembly includes a fixed plate 22 fixed to the outside of the telescopic column 32, four second springs 21 fixed to one side of the fixed plate 22, and a cross push plate 18 fixed to one end of each second spring 21.

[0037] The cross-shaped pusher disc 18 is externally rotatably connected to four push rods 15, and each push rod 15 is rotatably connected to a fixing block 24 at one end. A clamping plate 9 is fixed to one end of the fixing block 24, which can drive the clamping plate 9 to expand for squeezing and clamping the fixed pipe fitting.

[0038] A robotic arm 13 is installed on one side of the upper surface of the base 1, and a laser welder 31 is installed at one end of the robotic arm 13. The robotic arm 13 can drive the laser welder 31 to weld the joint of the pipe fittings into a tee pipe.

[0039] The telescopic column 32 is externally slidably connected to an H-shaped slide plate 17, and the H-shaped slide plate 17 is externally rotatably connected to an L-shaped flip rod 16. The L-shaped flip rod 16 is used to flip and clamp the pipe fitting, enabling the pipe fitting to be assembled with the pipe fitting to form a tee pipe.

[0040] Specifically, in existing technologies, pipe fittings are typically placed flat on a workbench and clamped and fixed using a clamping mechanism. Then, another pipe fitting is joined and installed on the outside of the first fitting to form a tee fitting. Simultaneously, a laser welder is controlled to weld and fix the fittings around the joint. However, existing welding equipment has difficulty clamping and positioning the joined tee fittings during manufacturing. It also fails to press down on the two fittings joined together, making the gap at the joint smaller. This results in a larger gap at the joint of the welded tee fittings, leading to reduced internal compressive strength and low welded structural strength.

[0041] In the manufacturing process of the tee pipe, the pipe fitting is installed outside the rotating column 4, while the telescopic column 32 is driven to slide out of the rotating column 4, causing the fixed plate 22 to move synchronously. Simultaneously, the fixed plate 22 drives the second spring 21 to move, which in turn drives the cross-shaped push plate 18 to move. The cross-shaped push plate 18 then drives the push rod 15 to rotate, and the push rod 15 pushes the fixed block 24 to expand. This, in turn, causes the fixed block 24 to drive the clamping plate 9 to expand. The clamping plate 9 then expands and clamps the pipe fitting outside the rotating column 4, while simultaneously installing the pipe fitting to be welded outside the L-shaped rotating rod 16. The telescopic column 32 is then continuously driven to move. After the clamping plate 9 clamps and fixes the pipe fitting, the continuous movement of the telescopic column 32 drives the fixed plate 22 to move. 2. The second spring 21 is compressed, and at the same time, the telescopic column 32 drives the H-shaped slide 17 to move, and the H-shaped slide 17 pushes the L-shaped flipping rod 16 to flip. During the flipping process, the L-shaped flipping rod 16 clamps the external pipe and pushes the pipe to dock with the pipe clamped and fixed outside the rotating column 4, so that it fits tightly with the pipe outside the rotating column 4. Then, the robotic arm 13 is started to drive the welding angle of the laser welder 31, and at the same time, it drives the gear ring 3 to rotate, and the gear ring 3 drives the rotating column 4 to rotate, which in turn drives the docked pipe to rotate. At the same time, the robotic arm 13 adjusts the welding angle of the laser welder 31 in real time and welds and fixes the docked pipe, thereby realizing the processing and manufacturing of the tee pipe and solving the above problems.

[0042] like Figure 1 , Figure 3 and Figure 5 As shown, four limiting posts 23 are fixedly connected to one side of the cross-shaped push disk 18, and the four limiting posts 23 are slidably connected to the rotating post 4.

[0043] like Figure 2 , Figure 3 and Figure 5 As shown, the telescopic column 32 is provided with a protrusion 26 on the outside, and a cross abutment 25 is fixedly connected to one end of the telescopic column 32. The H-shaped slide plate 17 is slidably connected between the protrusion 26 and the cross abutment 25.

[0044] Specifically, by driving the telescopic column 32 to slide out of the rotating column 4, the telescopic column 32 moves the fixed plate 22. Simultaneously, the second spring 21 moves the cross-shaped push plate 18, which in turn moves the limiting column 23 out of the rotating column 4, thus pushing the clamping plate 9 to expand and clamp the pipe fitting. After clamping and fixing the pipe fitting, by continuously driving the telescopic column 32, the fixed plate 22 is compressed by the telescopic column 32, and the telescopic column 32 uses the protrusion 26 to push the H-shaped slide plate 17, which in turn moves the L-shaped flipping rod 16. The L-shaped flipping rod 16 clamps and abuts against the inner wall of the pipe fitting, allowing the pipe fitting to connect with the outer pipe fitting of the rotating column 4 and fit tightly together. Then, the laser welder 31 is used to weld the pipe fittings together. This solves the problem that if the existing tee pipe fitting welding settings are not spliced ​​together during the processing and manufacturing of tee pipe fittings, and the pipe fittings are not clamped and fitted tightly together to reduce the gap at the joint, the gap at the joint will be too large when welding the pipe fittings together to manufacture the tee pipe. This will affect the structural strength of the manufactured tee pipe and cause the internal pressure that the tee pipe can withstand in the later stage to be insufficient.

[0045] like Figure 1 , Figure 3 and Figure 5 As shown, a mounting groove 6 is provided on one side of the rotating column 4, and an electric push rod 19 is installed in the inner cavity of the mounting groove 6. The piston rod end of the electric push rod 19 is fixedly connected to the telescopic column 32.

[0046] like Figure 2 , Figure 3 and Figure 5 As shown, the clamping plates 9 are fixed to one end of each other with a U-shaped fixing frame 14, and the L-shaped flipping rod 16 is rotatably connected to the inner cavity of the U-shaped fixing frame 14.

[0047] like Figure 2 , Figure 4 and Figure 5 As shown, multiple sleeves 7 are installed on the outside of the rotating column 4, and sliding columns 8 are slidably connected to the inner cavity of the multiple sleeves 7. The upper end of the sliding column 8 is fixedly connected to the clamping plate 9.

[0048] Specifically, during the assembly and preparation of the tee fitting, the fitting is installed outside the rotating column 4, while another fitting is installed outside the L-shaped flipping rod 16. Then, the electric push rod 19 is activated to drive the telescopic column 32 to move, which in turn drives the fixed plate 22 to move. This drives the clamping plate 9 to slide the sliding column 8 out of the sleeve 7 to expand, thereby clamping and fixing the fitting outside the rotating column 4. As the telescopic column 32 continues to move, it drives the H-shaped sliding plate 17 to move, which in turn drives the L-shaped flipping rod 16 to rotate and connect to the inner cavity of the U-shaped fixed frame 14. During the rotation, the L-shaped flipping rod 16 clamps and pushes the external fitting, and connects the pushed fitting with the fitting outside the rotating column 4, thereby improving the precision of the tee fitting assembly and ensuring the quality of welding and manufacturing.

[0049] Example 2: Figure 2 , Figure 4 and Figure 5 As shown, an L-shaped flip rod 16 has a storage groove 27 inside one end. A T-shaped slide rod 29 is slidably connected to the inner cavity of the storage groove 27. A tension spring 28 is fixed to one end of the T-shaped slide rod 29. One end of the tension spring 28 is fixed to the inner wall of the storage groove 27. A clamping block 30 is fixed to one end of the T-shaped slide rod 29.

[0050] Specifically, when clamping and splicing the tee pipe, the L-shaped flipping rod 16 is driven to rotate, causing the L-shaped flipping rod 16 to move the T-shaped sliding rod 29. Simultaneously, the T-shaped sliding rod 29 moves the clamping block 30, allowing the clamping block 30 to abut against the inner wall of the pipe fitting. As the L-shaped flipping rod 16 continues to rotate, the clamping block 30 pushes the inner wall of the pipe fitting against the outside of the rotating column 4 to splice the pipe fitting, thereby reducing the gap between the pipe fittings. When butt welding the pipe, the clamping plate 9 is used to clamp the pipe fitting. The device is held in place, and then the L-shaped flipping rod 16 drives the clamping block 30 to clamp another pipe fitting. At the same time, the L-shaped flipping rod 16 drives the clamping block 30 to rotate, and after the clamping block 30 clamps the pipe fitting, it pushes the pipe fitting to connect with the pipe fitting outside the clamping plate 9. This improves the practicality of the welding equipment, enabling it to clamp and connect different pipe fittings for production and processing. It solves the problem that existing tee pipe fitting welding equipment can only clamp and splice tee pipes, which is not only costly but also difficult to process and manufacture different types of pipe fittings.

[0051] like Figure 4 and Figure 5 As shown, a groove 10 is provided at the upper end of the clamping plate 9. A fixed slide rod 11 is fixedly connected to the inner cavity of the groove 10. A stop block 12 is slidably connected to the outside of the fixed slide rod 11. A first spring 20 is fixedly connected to one side of the stop block 12. One end of the first spring 20 is fixedly connected to the inner wall of the groove 10.

[0052] Specifically, during the splicing and manufacturing of the tee pipe, the pipe fitting is installed outside the clamping plate 9, and at the same time, the pipe fitting abuts against the abutment block 12, and the abutment block 12 slides outside the fixed slide rod 11, thereby squeezing the first spring 20. Then, the rebound force of the first spring 20 can be used to lift the abutment block 12, and the abutment block 12 pushes the pipe fitting to abut against the pipe fitting outside the L-shaped flip rod 16, ensuring the tightness of the connection and improving the quality of the welded tee pipe.

[0053] like Figure 1 , Figure 3 and Figure 7 As shown, the inner cavity of the fixed frame 2 is provided with a rotating groove 34, and the gear ring 3 is rotatably connected in the inner cavity of the rotating groove 34.

[0054] like Figure 1 , Figure 3 and Figure 7 As shown, a servo motor 5 is installed on one side of the fixed frame 2. The output shaft end of the servo motor 5 passes through the fixed frame 2 and is fixedly connected to a gear 33 in the inner cavity of the rotating groove 34. The gear 33 meshes with the gear ring 3.

[0055] Specifically, when welding the T-pipe, the servo motor 5 is started to drive the gear 33 to rotate, and the gear 33 meshes with the transmission gear ring 3 to rotate, which in turn drives the rotating column 4 to rotate. At the same time, the rotating column 4 drives the fixed plate 22 and the clamping plate 9 to rotate synchronously, which in turn drives the spliced ​​T-pipe to rotate. Then, the robotic arm 13 controls the laser welder 31 to weld and fix the spliced ​​T-pipe joint, thereby improving the efficiency of T-pipe processing and manufacturing.

[0056] Working principle: During the processing and manufacturing of the tee pipe, the pipe fitting is installed outside the rotating column 4, while the telescopic column 32 is driven to slide out of the rotating column 4, causing the fixed plate 22 to move synchronously. Simultaneously, the fixed plate 22 drives the second spring 21 to move, which in turn drives the cross-shaped push plate 18 to move. The cross-shaped push plate 18 then drives the push rod 15 to rotate, and the push rod 15 pushes the fixed block 24 to expand. This, in turn, causes the fixed block 24 to drive the clamping plate 9 to expand. The clamping plate 9 then expands and clamps the pipe fitting outside the rotating column 4, while simultaneously installing the pipe fitting to be welded outside the L-shaped rotating rod 16. The telescopic column 32 is then continuously driven to move. After the clamping plate 9 clamps and fixes the pipe fitting, the continuous movement of the telescopic column 32 will... The fixed plate 22 compresses the second spring 21, while the telescopic column 32 drives the H-shaped slide plate 17 to move and push the L-shaped flipping rod 16 to flip. During the flipping process, the L-shaped flipping rod 16 clamps the external pipe and pushes the pipe to connect with the pipe clamped and fixed outside the rotating column 4, so that it fits tightly with the pipe outside the rotating column 4. Then, the robotic arm 13 drives the welding angle of the laser welder 31 and drives the gear ring 3 to rotate, which in turn drives the rotating column 4 to rotate, thereby driving the connected pipe to rotate. At the same time, the robotic arm 13 adjusts the welding angle of the laser welder 31 in real time and welds and fixes the connected pipe, thereby realizing the processing and manufacturing of the tee pipe.

[0057] The telescopic column 32 is driven to slide out of the rotating column 4 and move, which in turn moves the fixed plate 22. At the same time, the second spring 21 drives the cross push plate 18 to move, which in turn drives the limiting column 23 to slide out of the rotating column 4 and move, thereby pushing the clamping plate 9 to expand and clamp the pipe. After the pipe is clamped and fixed, the telescopic column 32 is continuously driven to move, which in turn drives the fixed plate 22 to squeeze the second spring 21. At the same time, the telescopic column 32 uses the protrusion 26 to push the H-shaped slide plate 17 to move, which in turn drives the L-shaped flipping rod 16 to flip. The L-shaped flipping rod 16 abuts and clamps the inner wall of the pipe, so that the pipe is connected to the pipe outside the rotating column 4 and fits tightly. Then, the laser welder 31 is used to weld the pipe to the pipe.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
