Description

Technical Field

[0001] The present invention relates to the technical field of welding for machining, and specifically to a welding device for automated machining. Background Art

[0002] In machining, welding equipment is required to weld metal products to fix their shapes or connect them to other metal products. Therefore, welding provides great convenience for the processing of metal products. With the development of science and technology, intelligent machinery has been introduced into each field. In machining, automated welding equipment has also emerged, which replaces manual labor to complete welding work, improving work efficiency and reducing welding costs.

[0003] Automatic submerged arc welding is a common arc welding process. During welding, a sufficient amount of flux is spread on the welding surface. To ensure that the flux can be quickly discharged from the outlet, there will be enough air remaining between the granular fluxes. Moreover, the welding head adopts a one-end feeding method, which makes it difficult to balance the total amount of flux at both ends during the discharging process at the discharging end. As a result, after discharging, the heat insulation effects at both ends of the welding area are different, ultimately causing the problem of different cooling efficiencies in the welding area. In response to the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a welding device for automated machining, including a transmission pipe. A wire inlet pipe is fixedly connected to the top of the transmission pipe. A mounting bracket is fixedly connected to the outer wall of the wire inlet pipe. A metal wire is slidably connected to the inner wall of the wire inlet pipe. A heat melter is fixedly connected to the inner wall of the transmission pipe. The device further includes:

[0005] A material limiting mechanism, fixedly connected to the bottom of the transmission pipe, for discharging flux to cover the inside of the welding area;

[0006] A limiting mechanism, slidably connected to the bottom of the material limiting mechanism, for restricting the opening and closing of the material limiting mechanism;

[0007] A supporting mechanism, slidably connected to the inner wall of the limiting mechanism, for the material limiting mechanism to transmit the pressure of the accumulated flux to the outer wall of the limiting mechanism through the supporting mechanism. When the flux in the transmission pipe is not full, the material limiting mechanism will be in a closed state;

[0008] Among them, before use, first fix the mounting bracket at the required position, insert the metal wire through the wire inlet pipe, and pass it downward through the heat melter.

[0009] Preferably, the material limiting mechanism includes:

[0010] A feeding component, fixedly connected to the outer wall of the transmission pipe;

[0011] The shielding component is fixedly connected to the inner wall of the transmission pipe through a limiting component;

[0012] The limiting component includes a first support frame fixedly connected to the inner wall of the transmission pipe. A first rotating rod is fixedly connected to the inner wall of the through hole of the first support frame, and a semi-circular rotating plate is rotatably connected to the outer wall of the first rotating rod;

[0013] Among them, the feeding component transports external granular soldering flux into the transmission pipe, while the shielding component restricts the flow of the soldering flux.

[0014] Preferably, the limiting mechanism includes:

[0015] A sliding component fixedly connected to the bottom of the shielding component;

[0016] A limiting component slidably connected to the inner wall of the sliding component;

[0017] Among them, the pressure generated by the shielding component is transmitted to the sliding component and the limiting component through the support mechanism, and the shielding component does not rotate.

[0018] Preferably, the support mechanism includes:

[0019] A buckle component slidably connected to the inner wall of the limiting component;

[0020] A linkage component rotatably connected to the inner wall of the shielding component;

[0021] Among them, when the shielding component rotates downward, it is transmitted to the buckle component through the linkage component, causing the buckle component to contract and releasing the buckle restriction of the buckle component.

[0022] Preferably, the feeding component includes a feeding pipe penetratingly connected to the top of the transmission pipe. A fixed block is penetratingly connected to the bottom of the transmission pipe, and a discharge pipe is fixedly connected to the bottom of the fixed block;

[0023] Among them, there is a gap between the discharge pipe and the hot melt device, which enables the soldering flux to fall downward through the above gap.

[0024] Preferably, the shielding component includes an annular clamping plate fixedly connected to the top of the semi-circular rotating plate, and an annular groove is provided at the bottom of the first support frame;

[0025] Among them, when there is too much soldering flux on the top of the semi-circular rotating plate, the pressure generated by the soldering flux will force the semi-circular rotating plate to rotate around the first rotating rod, compress the torsion spring to twist, and accumulate mechanical power.

[0026] Preferably, the sliding component includes a limiting square pipe fixedly connected to the bottom of the first support frame. Two first sliding rails are fixedly connected to the side wall of the limiting square pipe, and a sliding frame is slidably connected to the inner walls of the two first sliding rails;

[0027] Among them, the sliding carriage will slide up and down along the inner wall of the first slide rail, and at the same time drive the buckle assembly to slide up and down synchronously.

[0028] Preferably, the limiting assembly includes two second support frames fixedly connected to the outer wall of the limiting square tube, and a toothed rod is fixedly connected to the outer walls of the two second support frames;

[0029] Among them, the toothed rod will limit the downward sliding of the buckle assembly. When the buckle assembly slides upward, the arc surface of the toothed rod will contact the inner arc surface of the buckle assembly, and cause the buckle assembly to contract.

[0030] Preferably, the buckle assembly includes a sliding block slidably connected to the inner wall of the second support frame, a bevel slide rod is slidably connected to the inner wall of the sliding block, a rotating column is rotatably connected to the outer wall of the bevel slide rod, and a first spring is fixedly connected to the side wall of the bevel slide rod;

[0031] Among them, when the sliding block slides upward along the inner wall of the second support frame, the bevel surface of the bevel slide rod will contact the arc surface of the toothed rod, and force the bevel slide rod to slide inward, and compress the first spring to store mechanical power.

[0032] Preferably, the linkage assembly includes a second fixed block fixedly connected to the bottom of the semi-circular rotating plate, a second rotating rod is rotatably connected to the bottom of the second fixed block, and the end of the second rotating rod away from the second fixed block is rotatably connected to the outer wall of the rotating column;

[0033] Among them, the second fixed block and the second rotating rod are divided into two groups and are distributed on both sides of the limiting square tube. Among them, the sliding assembly and the limiting assembly are also divided into two parts and are fixed on both sides of the limiting square tube.

[0034] The present invention has the following beneficial effects:

[0035] (1) Aiming at the problem that there are differences in the left and right of the flux discharge, the present invention is provided with two groups of limiting mechanisms and supporting mechanisms inside the equipment. Even if one bevel slide rod is far away from the outer wall of the toothed rod, the other group is under less pressure, resulting in the rotating column still being stuck inside the toothed rod, restricting the two sliding carriages and the sliding block from sliding downward. Through the application of the above components, the flux first accumulates on the top of the semi-circular rotating plate, and after the accumulation is completed, the semi-circular rotating plate rotates downward, so that the accumulated flux flows downward through the gap between the semi-circular rotating plate and the first support frame, and finally flows downward through the gap between the discharge pipe and the hot melt device to reach the surface of the welding material, effectively avoiding the left and right deviation of the flux flowing out from the transmission pipe due to the single-directional feeding of the flux, which affects the heat insulation effect of the flux.

[0036] (2) By utilizing the downward rotation characteristic of the above-mentioned semi-circular rotating plate, a shielding component is provided inside the device. When the semi-circular rotating plate rotates downward by a small angle under the action of gravity, the annular clamping plate is still on the inner wall of the annular groove at this time, ensuring the sealing between the semi-circular rotating plate and the first support frame, and preventing the flux at the top of the semi-circular rotating plate from dropping downward due to the small downward inclination of the semi-circular rotating plate.

[0037] (3) After the above-mentioned semi-circular rotating plate rotates downward, the torsion spring will be deformed under pressure and forced to store potential energy. Therefore, after the device completes the welding of a single object, the external material pipe will cut off the feeding into the feeding pipe at this time. The total amount of flux in the transmission pipe decreases, and the pressure on the semi-circular rotating plate also decreases synchronously. Finally, the semi-circular rotating plate will reset under the pulling of the torsion spring. The semi-circular rotating plate drives the sliding block to slide upward along the inner wall of the second support frame through the linkage component and the rotating column. At this time, the arc surface of the inclined plane slide rod will contact the inclined plane of the toothed rod, forcing the inclined plane slide rod to contract and causing the sliding block to move upward and reset. At this time, the semi-circular rotating plate will block the through hole of the first support frame again, and the annular clamping plate is inserted into the annular groove. Through the application of the above components, after the device completes welding, it can block the flux in the transmission pipe, preventing the residual flux in the transmission pipe from flowing out and falling onto the production line during the process of replacing the welding material at the bottom, which affects the automated machining.

[0052] Example 1, please refer to Figures 1-5 , the present invention is a welding device for automated mechanical processing, including a transmission pipe 13. A wire inlet pipe 14 is fixedly connected to the top of the transmission pipe 13. A mounting rack 15 is fixedly connected to the outer wall of the wire inlet pipe 14. A metal wire 16 is slidably connected to the inner wall of the wire inlet pipe 14. A heat melter 17 is fixedly connected to the inner wall of the transmission pipe 13. It further includes:

[0053] A material limiting mechanism 1, which is fixedly connected to the bottom of the transmission pipe 13 and is used to discharge the flux and cover the inside of the welding area;

[0054] The limiting mechanism 2 is slidably connected to the bottom of the material limiting mechanism 1 and is used to limit the opening and closing of the material limiting mechanism 1;

[0055] The supporting mechanism 3 is slidably connected to the inner wall of the limiting mechanism 2 and is used for the material limiting mechanism 1 to transmit the pressure of the solder flux accumulation to the outer wall of the limiting mechanism 2 through the supporting mechanism 3. When the solder flux in the transmission pipe 13 is in an unfilled state, the material limiting mechanism 1 will be in a closed state;

[0056] Among them, before use, first fix the mounting bracket 15 at the required position, then insert the metal wire 16 into the inside of the wire inlet pipe 14, and make the metal wire 16 pass through the transmission pipe 13 and the heat melter 17, and finally extend outward from the bottom, and the external granular solder flux can be transmitted to the inside of the transmission pipe 13 through the feed pipe 111.

[0057] The material limiting mechanism 1 includes:

[0058] The feeding component 11 is fixedly connected to the outer wall of the transmission pipe 13;

[0059] The shielding component 12 is fixedly connected to the inner wall of the transmission pipe 13 through a limiting member;

[0060] The limiting member includes a first support frame 121 fixedly connected to the inner wall of the transmission pipe 13. A rotating rod 122 is fixedly connected to the inner wall of the through hole of the first support frame 121, and a semi-circular rotating plate 123 is rotatably connected to the outer wall of the rotating rod 122;

[0061] Among them, the feeding component 11 transports the external granular solder flux into the inside of the transmission pipe 13, while the shielding component 12 restricts the flow of the solder flux.

[0062] The limiting mechanism 2 includes:

[0063] The sliding component 21 is fixedly connected to the bottom of the shielding component 12;

[0064] The limiting component 22 is slidably connected to the inner wall of the sliding component 21;

[0065] Among them, the pressure generated by the shielding component 12 is transmitted to the sliding component 21 and the limiting component 22 through the supporting mechanism 3, and the shielding component 12 will not rotate.

[0066] The supporting mechanism 3 includes:

[0067] The buckle component 31 is slidably connected to the inner wall of the limiting component 22;

[0068] The linkage component 32 is rotatably connected to the inner wall of the shielding component 12;

[0069] When the shielding component 12 rotates downward, it is transmitted to the buckle component 31 through the linkage component 32, causing the buckle component 31 to contract and releasing the buckle restriction of the buckle component 31.

[0070] Embodiment 2. Please refer to Figures 2-10 , the present invention is a welding device for automated mechanical processing. On the basis of Embodiment 1, the feeding component 11 includes a feeding pipe 111 connected to the top of the transmission pipe 13 in a through manner. The bottom of the transmission pipe 13 is connected to a fixed block 112 in a through manner, and the bottom of the fixed block 112 is fixedly connected to a discharge pipe 113;

[0071] There is a gap between the discharge pipe 113 and the hot melt device 17, which enables the flux to fall downward through the above gap.

[0072] The shielding component 12 includes an annular clamping plate 124 fixedly connected to the top of the semi-circular rotating plate 123, and an annular groove 125 is formed at the bottom of the support frame 121;

[0073] Taking advantage of the characteristic that the above semi-circular rotating plate 123 rotates downward, a shielding component 12 is arranged inside the device. When the semi-circular rotating plate 123 first rotates downward by a small angle under the action of gravity, the annular clamping plate 124 is still on the inner wall of the annular groove 125 at this time, ensuring the sealing between the semi-circular rotating plate 123 and the support frame 121, and preventing the flux on the top of the semi-circular rotating plate 123 from falling downward due to the small downward inclination of the semi-circular rotating plate 123;

[0074] Among them, when there is too much flux on the top of the semi-circular rotating plate 123, the pressure generated by the flux will force the semi-circular rotating plate 123 to rotate around the rotating rod 122, compress the torsion spring 126 to twist, and accumulate mechanical power.

[0075] The sliding component 21 includes a limiting square tube 211 fixedly connected to the bottom of the support frame 121. Two slide rails 212 are fixedly connected to the side wall of the limiting square tube 211, and a sliding frame 213 is slidably connected to the inner walls of the two slide rails 212;

[0076] Among them, the sliding frame 213 will slide up and down along the inner wall of the slide rail 212, and at the same time drive the buckle component 31 to slide up and down synchronously.

[0077] The limiting component 22 includes two support frames 221 fixedly connected to the outer wall of the limiting square tube 211, and a toothed rod 222 is fixedly connected to the outer walls of the two support frames 221;

[0078] Among them, the toothed rod 222 will limit the downward sliding of the buckle component 31. When the buckle component 31 slides upward, the arc surface of the toothed rod 222 will contact the inner arc surface of the buckle component 31, causing the buckle component 31 to contract;

[0079] After the above-mentioned semi-circular rotating plate 123 rotates downward, the torsion spring 126 will be compressed and deformed, forcing the torsion spring 126 to store potential energy. Therefore, after the device completes the welding of a single object, at this time, the external material pipe will cut off the feeding to the feeding pipe 111. At this time, the total amount of flux inside the transfer pipe 13 decreases, and the pressure on the semi-circular rotating plate 123 also decreases synchronously. Finally, the semi-circular rotating plate 123 will reset under the pulling of the torsion spring 126. The semi-circular rotating plate 123 drives the sliding block 311 to slide upward along the inner wall of the second support frame 221 through the linkage assembly 32 and the rotating column 313. At this time, the arc surface of the inclined plane slide bar 312 will contact the inclined plane of the toothed bar 222, forcing the inclined plane slide bar 312 to contract and causing the sliding block 311 to move upward and reset. At this time, the semi-circular rotating plate 123 will block the through hole of the first support frame 121 again, and the annular clamping plate 124 is inserted into the annular groove 125. Through the application of the above components, after the device completes welding, it can block the flux inside the transfer pipe 13, avoiding the flux remaining inside the transfer pipe 13 from flowing out and falling onto the production line due to external shaking during the process of replacing the welding material at the bottom, which affects the automated machining.

[0080] The buckle assembly 31 includes a sliding block 311 slidably connected to the inner wall of the second support frame 221. An inclined plane slide bar 312 is slidably connected to the inner wall of the sliding block 311. A rotating column 313 is rotatably connected to the outer wall of the inclined plane slide bar 312. A first spring 314 is fixedly connected to the side wall of the inclined plane slide bar 312;

[0081] If the flux distribution on the top of the semi-circular rotating plate 123 is quite different, at this time, the pressures acting on the tops of the two semi-circular rotating plates 123 are also different. Since there are two groups of limiting mechanisms 2 and supporting mechanisms 3 inside the device, even if one inclined plane slide bar 312 is away from the outer wall of the toothed bar 222, the other group, due to the smaller pressure received, causes the rotating column 313 to still be stuck inside the toothed bar 222, restricting the two sliding frames 213 and the sliding block 311 from sliding downward. Through the application of the above components, the flux first accumulates on the top of the semi-circular rotating plate 123, and after the accumulation is completed, the semi-circular rotating plate 123 rotates downward, enabling the accumulated flux to flow downward through the gap between the semi-circular rotating plate 123 and the first support frame 121, and finally flowing downward from the gap between the discharge pipe 113 and the heat melter 17 to reach the surface of the welding material, effectively avoiding the left-right deviation of the flux flowing out from the transfer pipe 13 due to the single-direction feeding of the flux, which affects the heat insulation effect of the flux.

[0082] Among them, when the sliding block 311 slides upward along the inner wall of the second support frame 221, the inclined plane of the inclined plane slide bar 312 will contact the arc surface of the toothed bar 222, forcing the inclined plane slide bar 312 to slide inward and compressing the first spring 314 to store mechanical power.

[0083] The linkage component 32 includes a second fixed block 321 fixedly connected to the bottom of the semi-circular rotating plate 123. A second rotating rod 322 is rotatably connected to the bottom of the second fixed block 321. The end of the second rotating rod 322 away from the second fixed block 321 is rotatably connected to the outer wall of the rotating column 313;

[0084] When the flux enters the interior of the transfer tube 13, it will first accumulate on top of the first support frame 121 and the semi-circular rotating plate 123. At this time, the pressure received by the semi-circular rotating plate 123 will be transmitted to the rotating column 313 through the second rotating rod 322, and force the rotating column 313 to drive the inclined sliding rod 312 to horizontally move along the inner wall of the sliding block 311, as Figure Eight shown. The inclined sliding rod 312 moving horizontally to the left will move away from the outer wall of the toothed rod 222. At the same time, the downward pressure of the semi-circular rotating plate 123 will be transmitted to the sliding block 311 through the second rotating rod 322 and the rotating column 313, forcing the sliding block 311 to have a downward sliding tendency;

[0085] The second fixed block 321 and the second rotating rod 322 are divided into two groups and are distributed on both sides of the limiting square tube 211. The sliding component 21 and the limiting component 22 are also divided into two parts and are fixed on both sides of the limiting square tube 211.

[0086] A specific application of this embodiment is as follows: Before the present invention is used, the mounting bracket 15 is first fixed at the required position. Subsequently, the metal wire 16 is inserted into the interior of the wire inlet tube 14, and the metal wire 16 is made to pass through the transfer tube 13 and the hot melt device 17, and finally extends outward from the bottom. Moreover, the external granular flux can be transmitted into the interior of the transfer tube 13 through the feed tube 111;

[0087] When the flux enters the interior of the transfer tube 13, it will first accumulate on top of the first support frame 121 and the semi-circular rotating plate 123. At this time, the pressure received by the semi-circular rotating plate 123 will be transmitted to the rotating column 313 through the second rotating rod 322, and force the rotating column 313 to drive the inclined sliding rod 312 to horizontally move along the inner wall of the sliding block 311, as Figure Eight, the inclined plane slide bar 312 moving horizontally to the left will move away from the outer wall of the rack bar 222. At the same time, the downward pressure of the semi-circular rotating plate 123 will be transmitted to the sliding block 311 through the second rotating rod 322 and the rotating column 313, forcing the sliding block 311 to have a downward sliding tendency. If there is a large difference in the distribution of the soldering flux on the top of the semi-circular rotating plate 123, the pressures acting on the tops of the two semi-circular rotating plates 123 are also different at this time. Since there are two sets of limiting mechanisms 2 and supporting mechanisms 3 inside the device, even if one inclined plane slide bar 312 moves away from the outer wall of the rack bar 222, the other set, due to the smaller pressure received, causes the rotating column 313 to still be stuck inside the rack bar 222, restricting the downward sliding of the two sliding frames 213 and the sliding block 311. Through the application of the above components, the soldering flux first accumulates on the top of the semi-circular rotating plate 123, and after the accumulation is completed, the semi-circular rotating plate 123 rotates downward, so that the accumulated soldering flux flows downward through the gap between the semi-circular rotating plate 123 and the first support frame 121, and finally flows downward through the gap between the discharge pipe 113 and the hot melt device 17 to reach the surface of the welding material, effectively avoiding the left-right deviation of the soldering flux flowing out from the transfer pipe 13 due to the single-directional feeding of the soldering flux, which affects the heat insulation effect of the soldering flux.

[0088] Utilizing the characteristic that the above semi-circular rotating plate 123 rotates downward, a shielding component 12 is arranged inside the device. When the semi-circular rotating plate 123 first rotates downward by a small angle under the action of gravity and forces the rotating column 313 to compress the first spring 314, the annular clamping plate 124 is still on the inner wall of the annular groove 125 at this time, so that after the semi-circular rotating plate 123 pushes the inclined plane slide bar 312 to slide, the sealing performance between the semi-circular rotating plate 123 and the first support frame 121 is ensured, and the soldering flux on the top of the semi-circular rotating plate 123 is prevented from falling downward due to the small downward inclination of the semi-circular rotating plate 123.

[0089] After the above-mentioned semi-circular rotating plate 123 rotates downward, the torsion spring 126 will be compressed and deformed, and the torsion spring 126 will be forced to store potential energy. Therefore, after the device completes the welding of a single object, at this time, the external material pipe will cut off the feeding to the feeding pipe 111. At this time, the total amount of flux inside the transmission pipe 13 decreases, and the pressure on the semi-circular rotating plate 123 also decreases synchronously. Finally, the semi-circular rotating plate 123 will reset under the pulling of the torsion spring 126. The semi-circular rotating plate 123 drives the sliding block 311 to slide upward along the inner wall of the second support frame 221 through the linkage assembly 32 and the rotating column 313. At this time, the arc surface of the inclined surface slide bar 312 will contact the inclined surface of the rack 222, forcing the inclined surface slide bar 312 to contract and causing the sliding block 311 to move upward and reset. At this time, the semi-circular rotating plate 123 will block the through hole of the first support frame 121 again, and the annular clamping plate 124 is inserted into the annular groove 125. Through the application of the above components, after the device completes the welding, it can block the flux inside the transmission pipe 13, avoiding the flux remaining inside the transmission pipe 13 from flowing out and falling onto the production line due to external shaking during the process of replacing the welding material at the bottom, which affects the automated machining.
