[0001] The present application relates to the technical field of tubing head processing, in particular to a welding device with anti-skid limiting structure for tubing head processing. BACKGROUND

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metal or other thermoplastic materials such as plastic by heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flame, electric arc, laser, electron beam, friction and ultrasonic wave, etc. When welding the tubing head, the limiting structure generally uses mechanical limiting or control limiting structure to clamp and limit the tubing head. However, the existing mechanical limiting or control limiting structure has a small contact area with the tubing head, the limiting effect is not ideal, the welding piece is not easy to connect with the tubing head, and when welding with a welding gun, the position of the welding gun is not easy to adjust, which affects the coverage effect of welding on the tubing head. At the same time, the surface of the existing tubing head after welding is left with high-temperature welding, which can cause hand burns when manually touched by personnel. SUMMARY

[0003] The present application aims to solve the problems in the prior art, such as the limiting structure generally using mechanical limiting or control limiting structure to clamp and limit the tubing head when welding the tubing head, the existing mechanical limiting or control limiting structure having a small contact area with the tubing head, the limiting effect being not ideal, the welding piece being not easy to connect with the tubing head, and the position of the welding gun being not easy to adjust when welding with a welding gun, which affects the coverage effect of welding on the tubing head, and the surface of the existing tubing head after welding being left with high-temperature welding, which can cause hand burns when manually touched by personnel.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a welding device with anti-skid limiting structure for tubing head processing, comprising a limiting structure, the limiting structure being fixedly installed with welding spraying structures at both ends; The limiting structure comprises an adsorption limiting assembly fixedly installed with an auxiliary adjusting limiting assembly, and the adsorption limiting assembly comprises a base table with a controller on one side, and a cylindrical concave table with an electromagnet inside is fixedly installed above the base table; The base table is fixedly installed with mounting columns on both sides and the rear side, and a mounting frame is fixedly installed above the mounting columns, a bidirectional ball screw with a bidirectional ball nut on the surface is rotatably arranged in the mounting frame, one end of the bidirectional ball screw penetrates through the mounting frame and is fixedly installed with a driving motor output end, and the driving motor is fixedly installed on one side of the outer wall of the mounting frame.

[0010] Preferably, a guide spring rod is installed inside the mounting hole, and a magnet post is fixedly installed at one end of the guide spring rod, while the magnet posts are evenly distributed on the surface of the mounting body.

[0011] By adopting the above technical solution, the guide spring rod is set to achieve the function of elastic force adjustment.

[0012] Preferably, the welding spray structure includes an installation cylinder with a hollow internal structure, and a connecting bearing is fixedly installed inside the installation cylinder. At the same time, an internal gear disc is fixedly installed on the inner ring of the connecting bearing. A connecting disc with a hollow internal structure is welded and fixedly installed on one side of the internal gear disc. An adsorption block with a hollow internal structure is embedded and fixedly installed above the surface of the connecting disc. At the same time, a water injection hole is opened above the adsorption block and is connected to the inside of the connecting disc.

[0013] By adopting the above technical solution, the internal gear disc is used to adjust the meshing rotation.

[0014] Preferably, a spherical universal connector is fixedly installed on the surface of the connecting plate, and a welding gun and a spray head are conveniently fixedly installed at one end of the spherical universal connector. At the same time, the spray head is connected to the spherical universal connector and the connecting plate. A rotary motor is fixedly installed on one side inside the mounting cylinder, and a drive gear that meshes with the internal gear plate is fixedly installed at the output end of the rotary motor. Meanwhile, a through hole is opened on one side above the surface of the mounting cylinder to facilitate the through connection of the elastic corrugated conveying pipe.

[0015] By adopting the above technical solution, the spherical universal connector is used to achieve rotational connection and adjustment.

[0016] Preferably, one end of the elastic corrugated conveying pipe is embedded and fixed to the electromagnet cover, and the electromagnet cover is connected to the adsorption block for adsorption. At the same time, the other end of the elastic corrugated conveying pipe is installed and connected to one end of the branch pipe.

[0018] Preferably, the upper side of the mounting cylinder is fixedly installed with one end of the second electric telescopic rod, and the other end of the second electric telescopic rod is fixedly installed with one side below the mounting frame.

[0019] By adopting the above technical solution, the second electric telescopic rod is installed to control the telescopic adjustment.

[0020] Preferably, the water tank is fixedly installed above the mounting frame, and a rotation displacement module is fixedly installed in front of the adsorption block.

[0021] By adopting the above technical solution, the rotational displacement module is set up to transmit rotational displacement signals.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the welding device for processing oil pipe heads with an anti-slip limiting structure, (1) In this case, the adsorption limiting component set in the limiting structure solves the problem that when welding the oil pipe head, the limiting structure generally adopts mechanical limiting or controlled limiting structure to clamp and limit the oil pipe head. However, the existing mechanical limiting or controlled limiting structure has a small contact area with the oil pipe head and the limiting effect is not ideal. The welded parts and the oil pipe head are not easy to connect. When the oil pipe head needs to be welded and fixed, the oil pipe head is placed inside the cylindrical concave platform and the electromagnet is controlled to work to adsorb and fix the oil pipe head. The electromagnet increases the adsorption and limiting area at the bottom of the oil pipe head to avoid the oil pipe head from shaking and sliding displacement. (2) By setting up a welding spray structure, the position of the welding gun is not easy to rotate and adjust when welding with a welding gun, which affects the coverage effect of welding on the oil pipe head. When the oil pipe head needs to be welded to the welding part, the installation cylinder is passed through both ends of the oil pipe head and then the welding gun is manually adjusted so that the welding gun is moved to the connection position between the welding part and the oil pipe head. Then, the rotating motor is controlled to drive the welding gun to be synchronously stressed and rotate along the welding part and the oil pipe head to weld and fix the welding part and the oil pipe head. (3) By setting up a welding spray structure, the problem of residual high temperature on the surface of the existing oil pipe head after welding is solved, which will cause burns to the hands when the personnel touch it manually. After the welding parts are welded to the oil pipe head, the rotation displacement module transmits the rotation displacement position of the adsorption block to the controller. At this time, the controller controls the rotation motor to run and make the adsorption block rotate under the electromagnetic cover for matching adsorption. At this time, the water pump runs and delivers the spray water in the water tank to the inside of the spray head and sprays it on the welding position of the welding parts and the oil pipe head for spray cooling. (4) By setting the auxiliary adjustment limit component in the limit structure, the displacement of the welded part after docking with the oil pipe head welding position is easily solved, resulting in inaccurate welding. When the welded part docks with the oil pipe head welding position, the electric slide rail group is controlled to drive the relative displacement of the installation body. When the installation body is relatively displaced, the magnetic column and the installation body are used to perform relative auxiliary clamping adsorption limit on the welded part after docking. (5) By setting an adsorption limiting component, the problem of using an arc-shaped clamping plate to clamp and limit the oil pipe head when the electromagnet cannot adsorb and limit it is solved. The arc-shaped clamping plate also provides double limiting when clamping and limiting the oil pipe head. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-11 This invention provides a technical solution: a welding device for processing oil pipe heads with an anti-slip limiting structure, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a limiting structure 1, which includes an adsorption limiting component 101 fixedly installed on the auxiliary adjustment limiting component 102. The adsorption limiting component 101 includes a base platform 1011 with a controller on one side, and a cylindrical recess 1012 with an electromagnet 1013 inside is fixedly installed on the base platform 1011. Among them, the electromagnet 1013 and the cylindrical concave platform 1012 are both set with existing technology components. When set with existing technology components, they can effectively place and limit the oil pipe heads of different diameters. Furthermore, in the above scheme, mounting columns 1014 are fixedly installed on both sides and the rear side of the base platform 1011, and mounting frames 1015 are fixedly installed on the top of the mounting columns 1014. At the same time, a bidirectional ball screw 1016 with a bidirectional ball nut 1017 on its surface is rotatably installed inside the mounting frame 1015. One end of the bidirectional ball screw 1016 passes through the mounting frame 1015 and is fixedly installed at the output end of the drive motor 1018. The drive motor 1018 is fixedly installed on one side of the outer wall of the mounting frame 1015. Among them, the above-mentioned components constitute a bidirectional drive adjustment structure, which effectively assists in adjusting and clamping the oil pipe heads of different diameters when using the bidirectional drive adjustment structure composed of the above-mentioned components. Furthermore, in the above scheme, a mounting bracket 1019 is fixedly installed at the bottom of the bidirectional ball nut 1017, which extends through the mounting frame 1015 and below the mounting frame 1015. At the bottom of the mounting bracket 1019, an arc-shaped clamping plate 10111 for auxiliary clamping and limiting of the oil pipe head is fixedly installed at the output end of the first electric telescopic rod 10110. The aforementioned components constitute a lifting and adjusting structure. When the lifting and adjusting structure is formed by the aforementioned components, it effectively adjusts and limits the oil pipe head at different heights. Furthermore, the first electric telescopic rod 10110 and the arc-shaped clamping plate 10111 are both arranged symmetrically. When the two are arranged symmetrically, they effectively clamp and limit the two ends of the oil pipe head.

[0027] like Figure 5 , Figure 6 and Figure 7 As shown, the auxiliary adjustment limit assembly 102 includes a concave column 1021 fixed to the lower side of one side of the mounting bracket 1019, and an electric slide rail assembly 1022 is fixedly installed inside the concave column 1021. At the same time, another concave column 1021 is fixedly installed below the electric slide rail assembly 1022, and a mounting body 1024 with a mounting hole 1023 is fixedly installed inside the other concave column 1021 through another electric slide rail assembly 1022. Among them, there are 2 groups of 4 concave columns 1021, and each group of concave columns 1021 is arranged in a T-shape. When the concave columns 1021 are arranged in a T-shape, it is convenient to make the other concave column 1021 horizontally driven and adjusted. At the same time, the electric slide rail group 1022 also uses existing technology components. When using existing technology components, it can effectively drive and adjust the concave column 1021 and the mounting body 1024 in the left and right and up and down directions. Furthermore, in the above scheme, a guide spring rod 1025 is installed inside the mounting hole 1023, and a magnet post 1026 is fixedly installed at one end of the guide spring rod 1025. At the same time, the magnet posts 1026 are evenly distributed on the surface of the mounting body 1024. The components in the universal sleeve, which are composed of the aforementioned parts, are used to effectively adsorb, adjust, clamp, and limit the position of welded parts of different sizes and shapes when the universal sleeve structure is configured.

[0028] like Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the limiting structure 1 is fixedly installed with welding spray structure 2 at both ends. The welding spray structure 2 includes a mounting cylinder 201 with a hollow internal structure, and a connecting bearing 202 is fixedly installed inside the mounting cylinder 201. At the same time, an inner gear disk 203 is fixedly installed in the inner ring of the connecting bearing 202. A connecting disk 204 with a hollow internal structure is welded and fixedly installed on one side of the inner gear disk 203. An adsorption block 205 with a hollow internal structure is embedded and fixedly installed above the surface of the connecting disk 204. At the same time, a water injection hole 206 is opened above the adsorption block 205 and is connected to the inside of the connecting disk 204. The mounting cylinder 201 is provided in one set, and a single connecting bearing 202 is provided inside the single mounting cylinder 201. At the same time, a single internal gear disk 203 is fixed inside the inner ring of the single connecting bearing 202. The internal gear disk 203 is used to effectively adjust the synchronous force rotation of the connecting disk 204. Furthermore, the above scheme includes a spherical universal connector 207 fixedly installed on the surface of the connecting plate 204, and a welding gun 208 and a spray head 209 conveniently fixedly installed at one end of the spherical universal connector 207. At the same time, the spray head 209 is connected to the spherical universal connector 207 and the connecting plate 204. A rotary motor 2010 is fixedly installed on one side inside the mounting cylinder 201, and a drive gear 2011 that meshes with the internal gear plate 203 is fixedly installed at the output end of the rotary motor 2010. At the same time, a through hole is opened on one side above the surface of the mounting cylinder 201 to facilitate the through connection of the elastic corrugated conveying pipe 2012. The single connecting plate 204 has six spherical universal connectors 207 installed on one side. Four of these spherical universal connectors 207 are embedded and connected to the connecting plate 204 and the spray head 209. The remaining four spherical universal connectors 207 are installed and connected to the welding gun 208. The spherical universal connectors 207 facilitate the stretching or rotation adjustment of the welding gun 208 and the spray head 209 at any angle. The above components constitute a rotation adjustment structure, which effectively performs welding and spray cooling on the oil pipe head. Furthermore, in the above scheme, one end of the elastic corrugated conveying pipe 2012 is embedded and fixed to the electromagnet cover 2013, and the electromagnet cover 2013 is covered and connected to the adsorption block 205 for adsorption. At the same time, the other end of the elastic corrugated conveying pipe 2012 is installed and connected to one end of the branch pipe 2014. The electromagnet cover 2013 also uses existing technology components, and the existing technology components are used to effectively connect the adsorption block 205 to facilitate the injection of spray water. Furthermore, in the above scheme, one end of the second electric telescopic rod 2015 is fixedly installed on the upper side of the mounting cylinder 201, and the other end of the second electric telescopic rod 2015 is fixedly installed on the lower side of the mounting frame 1019. The other end of the branch pipe 2014 is installed on one end of the water pump 2016, and the water pump 2016 is fixedly installed above the water tank 2017. At the same time, the other end of the water pump 2016 is connected to the inside of the water tank 2017 through the extraction pipe. The water tank 2017 is fixedly installed above the mounting frame 1015. A rotation displacement module 2018 is fixedly installed in front of the adsorption block 205. The rotation displacement module 2018 also uses existing technology components. When using existing technology components, it can effectively monitor the rotation displacement position of the adsorption block 205 in real time, so that when the controller controls the rotation motor 2010 to work, the adsorption block 205 can be rotated to be directly above the electromagnet cover 2013 for docking and adsorption. The model of the rotation displacement module 2018 is: R36AS-RVDT.

[0029] In the above scheme, when the oil pipe head needs to be welded and fixed to the welded part, the oil pipe head is manually placed inside the cylindrical recess 1012 and comes into contact with the electromagnet 1013. Then, the controller controls the electromagnet 1013 to operate, thereby adsorbing and limiting the oil pipe head. When the electromagnet 1013 cannot adsorb oil pipe heads of different materials, the drive motor 1018 is controlled to operate, driving the bidirectional ball screw 1016 and the bidirectional ball nut 1017 to move relative to each other, and simultaneously driving the mounting bracket 1019, the first electric telescopic rod 10110 and the arc-shaped clamping plate 10111 to move relative to each other. When the arc-shaped clamping plate 10111 moves above the oil pipe head, the first electric telescopic rod 10110 is controlled to operate again, driving the arc-shaped clamping plate 10111 to move relative to each other. The arc-shaped clamping plate 10111 moves above the oil pipe head to adjust the clamping limit. When the arc-shaped clamping plate 10111 moves relative to the oil pipe head, it synchronously drives the mounting cylinder 201 and the mounting body 1024 to move relative to each other. When the mounting cylinder 201 passes through both ends of the oil pipe head, the drive motor 1018 stops operating. After the oil pipe head is clamped to the limit, the electric slide rail assembly 1022 is controlled to gradually adjust and clamp the welded part to both ends of the oil pipe head. Once the welded part is fixed to both ends of the oil pipe head, the operator manually adjusts the welding gun 208 to drive the spherical universal connector 207, causing the welding gun 208 tip to point towards the connection position between the welded part and the oil pipe head. Then, the operator controls the welding gun 208 and the rotary motor 2010. During operation, when the rotary motor 2010 is running, it drives the internal gear disk 203, connecting disk 204, connecting bearing 202, and welding gun 208 to rotate synchronously via the drive gear 2011. This facilitates the welding gun 208 to rotate and fix the welded part at the connection position with the oil pipe head. When the connecting disk 204 rotates under force, it synchronously drives the adsorption block 205 and the rotation displacement module 2018 to rotate synchronously under force. When the rotation displacement module 2018 rotates under force, it transmits the rotation displacement signal of the adsorption block 205 to the controller. After the welded part is connected to the oil pipe head, the controller controls the rotary motor 2010 to run again, causing the adsorption block 205 to rotate to its initial position. After the initial position is reached, the electromagnet cover 2013 is controlled to operate again and dock with the adsorption block 205. At this time, the water pump 2016 operates, supplying spray water from the water tank 2017 through the elastic corrugated conveying pipe 2012 and branch pipe 2014 into the connecting plate 204. The spray water entering the connecting plate 204 is sprayed onto the connection point between the welded part and the oil pipe head through the spherical universal connector 207 and spray head 209 for cooling. After the welding part and the oil pipe head connection point are cooled by spraying, the above steps are repeated in reverse to disassemble and separate the welded part from the oil pipe head and the cylindrical recess 1012. Oil pipe heads of different diameters are then placed and connected to the cylindrical recess 1012.At this point, the second electric telescopic rod 2015 is controlled to operate, causing the installation cylinder 201 to move downwards, thus facilitating the welding and fixing of oil pipe heads of different sizes and diameters through the installation cylinder 201.
