Description

Technical Field

[0001] The present invention relates to the technical field of pipe fitting manufacturing welding, and more specifically to an intelligent welding device for pipe fitting manufacturing. Background Art

[0002] Pipe fittings are a general term for parts that play the role of connection, control, direction change, diversion, sealing, support, etc. in pipeline systems. Steel pipe fittings are all pressure-bearing pipe fittings, and steel pipe fittings are divided into four categories according to different processing techniques, namely butt welding pipe fittings, socket welding and threaded pipe fittings, and flange pipe fittings.

[0003] When welding pipe fittings, you must first prepare the welding equipment and materials. For the surface of the steel pipe to be welded, it is necessary to clean and polish it to remove oil, oxides and other impurities. The steel pipe to be welded should be positioned and clamped with a clamp to ensure the stability and accuracy of the welding position. During the welding process, the welding rod or welding wire is brought into contact with the steel pipe joint, and the arc is used to generate heat to melt the welding material and melt it with the surface of the steel pipe. The surface of the pipe after welding should be cleaned and the welding slag should be removed. When welding pipe fittings, there are the following problems:

[0004] When welding pipe fittings, the two pipe fittings need to be aligned. Due to the tubular structure of the pipe fittings themselves, the axes of the two pipe fittings need to be aligned with each other. Nowadays, it is impossible to accurately position the pipe fittings. When the two pipe fittings are not aligned, the welded pipe fittings will tilt or deviate to a certain extent, which will make the welded pipe fittings scrapped.

[0005] After the pipe fittings are aligned and welded at one point, they need to be rotated to rotate the welding point of the two pipe fittings one circle to complete the welding work. Nowadays, the pipe fittings cannot be rotated automatically during welding. If one worker is welding and another worker is rotating the pipe fittings, it will cause a waste of personnel resources. If they are rotated after welding at a certain angle and then welded again, the work efficiency will be low. During welding, it is necessary to move back and forth at the welding point to ensure that the welding point can cover the pipe connection point, thereby ensuring the welding quality. The reciprocating welding work during welding requires a high level of staff and is prone to problems with low welding quality. Summary of the invention

[0020] 3. When the present invention completes the loading work of the second pipe fitting, the first pipe fitting is placed between the lower arc plate and the upper arc plate. When the side surface of the first pipe fitting contacts the side surface of the second pipe fitting, the threaded rod is rotated.

The intelligent welding device for pipe fitting manufacturing involved in the present invention is not limited to the various structures recorded in the following embodiments.

[0032] Reference Figure 1 and Figure 2 The present invention provides an intelligent welding device for pipe fitting manufacturing, comprising a supporting base 1, the top of the supporting base 1 is connected to an output reciprocating mechanism 2, the side of the output reciprocating mechanism 2 is fixedly connected to a clamping mechanism 3, the inside of the clamping mechanism 3 is movably connected to a first pipe fitting 4, the side of the supporting base 1 is fixedly connected to a feeding mechanism 5, the inside of the feeding mechanism 5 is movably connected to a second pipe fitting 6, a welding gun 7 is arranged above the second pipe fitting 6, the side of the welding gun 7 is fixedly connected to a welding machine body 8, the side of the first pipe fitting 4 and the side of the second pipe fitting 6 are in contact with each other, the contact surfaces of the first pipe fitting 4 and the second pipe fitting 6 are in the same shape, the axes of the first pipe fitting 4 and the second pipe fitting 6 coincide, and when the side of the first pipe fitting 4 and the side of the second pipe fitting 6 are in contact, the contact surface of the two is located directly below the welding gun 7.

[0033] In the embodiment of the present application, when welding the first pipe fitting 4 and the second pipe fitting 6, the axes of the first pipe fitting 4 and the second pipe fitting 6 coincide with each other. Therefore, when the first pipe fitting 4 and the second pipe fitting 6 are in contact, the docking between the two is sufficiently precise to ensure that there will be no eccentricity after welding the first pipe fitting 4 and the second pipe fitting 6, and the contact surface between the first pipe fitting 4 and the second pipe fitting 6 is located directly below the welding gun 7. When the welding gun 7 moves back and forth, it can cover the first pipe fitting 4 and the second pipe fitting 6 to avoid the presence of unwelded positions.

[0034] Reference Figure 3 , Figure 4 , Figure 5 as well as Figure 6The output reciprocating mechanism 2 includes a servo motor 201 for providing power, an output shaft 202 is fixedly connected to the side of the servo motor 201, an output gear 203 is fixedly connected to the side of the output shaft 202, a rotating gear 204 is meshed on the side of the output gear 203, a connecting rod 206 is fixedly connected to the side of the rotating gear 204 close to the servo motor 201, a connecting rod 206 is fixedly connected to the side of the clamping mechanism 3 away from the side of the rotating gear 204, a first bevel gear 207 is fixedly connected to the side of the output shaft 202 away from the servo motor 201, a second bevel gear 208 is meshed on the side of the first bevel gear 207 away from the servo motor 201, a speed-increasing gear set 209 is fixedly connected to the top of the second bevel gear 208, and the speed-increasing gear set 209 is away from the second The bottom end of the bevel gear 208 is fixedly connected with a synchronous gear 210, and the side of the synchronous gear 210 is meshed with a transmission gear 211. The inside of the transmission gear 211 is fixedly connected with a rotating shaft 212, and the top of the rotating shaft 212 is fixedly connected with an eccentric rod 213. The axes of the rotating shaft 212 and the eccentric rod 213 are parallel and do not overlap. The side of the eccentric rod 213 is movably connected with a reciprocating plate 214, and a sliding groove for the eccentric rod 213 to rotate is provided inside the reciprocating plate 214. The inside of the reciprocating plate 214 is movably connected with a fixed shaft 215, and both sides of the fixed shaft 215 are fixedly connected with a limit frame 216. The side of the rotating gear 204 away from the clamping mechanism 3 is movably connected with a limit ring 205, and the bottom end of the limit ring 205 is fixedly connected to the top of the supporting base 1.

[0035] In the embodiment of the present application, after the servo motor 201 is started, on the one hand, the output gear 203 drives the rotating gear 204 to rotate, and when the rotating gear 204 rotates, the clamping mechanism 3 is driven to rotate through the connecting rod 206. When the clamping mechanism 3 rotates, it will drive the first pipe fitting 4 inside it to rotate, and before the first pipe fitting 4 rotates, the welding gun 7 will weld the first pipe fitting 4 and the point directly above the second pipe fitting 6, so the first pipe fitting 4 will drive the second pipe fitting 6 to rotate. The present application can automatically complete the rotation of the first pipe fitting 4 and the second pipe fitting 6, and after the servo motor 201 is started, on the other hand, it will drive the first bevel gear 207 to rotate. When the first bevel gear 207 rotates, it drives the speed-increasing gear set 209 to rotate through the second bevel gear 208. After the speed-increasing gear set 209 rotates, the speed of the synchronous gear 210 is increased relative to the second bevel gear 208, and the synchronous gear 210 drives the transmission gear When 211 rotates, the speed of the transmission gear 211 will increase again. At this time, the speed of the rotating shaft 212 is high enough. When the rotating shaft 212 drives the eccentric rod 213 to rotate, the axial positions of the rotating shaft 212 and the eccentric rod 213 are different. Therefore, when the eccentric rod 213 rotates, the reciprocating plate 214 will reciprocate, and the moving direction of the reciprocating plate 214 is limited by the fixed shaft 215, and it will only reset and reciprocate along the axis of the fixed shaft 215. Therefore, the reciprocating plate 214 will drive the welding gun 7 to reciprocate along the axis of 515 at the contact point between the first pipe 4 and the second pipe 6, and the speed of the rotating shaft 212 is high, and it will reciprocate quickly to improve the welding quality. When the rotating gear 204 rotates, both sides of the rotating gear 204 are connected to the limit ring 205, and the limit ring 205 can support the rotating gear 204, and the structure of the limit ring 205 is as shown in Figure 6 As shown, Figure 4 In order to indicate the existence of the limit ring 205, the limit ring 205 is moved to the side of the rotating gear 204 close to the clamping mechanism 3. In fact, the limit ring 205 is on the side of the rotating gear 204 away from the clamping mechanism 3, and the gear shaft of the present application is movably connected to the supporting base 1, so that the gears connected to the gear shaft can rotate.

[0036] Reference Figure 6 and Figure 7The clamping mechanism 3 includes a lower arc plate 301 connected to the output reciprocating mechanism 2, a fixing pin 302 is fixedly connected to one side of the top of the lower arc plate 301, a threaded groove is provided inside the lower arc plate 301 away from the fixing pin 302, a rotating wheel 305 is threadedly connected in the threaded groove of the fixing pin 302, an upper arc plate 303 is movably connected to the side of the fixing pin 302, a threaded rod 306 is fixedly connected to the top of the rotating wheel 305, and the threaded rod 306 is located above the upper arc plate 303, a first supporting spring 304 is provided on the side of the fixing pin 302, and a second supporting spring 307 is provided on the side of the rotating wheel 305, both the first supporting spring 304 and the second supporting spring 307 are located between the lower arc plate 301 and the upper arc plate 303, and a limiting groove adapted to the first pipe fitting 4 is provided at the top of the lower arc plate 301 and the bottom of the upper arc plate 303.

[0037] In the embodiment of the present application, when the threaded rod 306 rotates, it drives the rotating wheel 305 to rotate. When the rotating wheel 305 rotates, it will move downward in the lower arc plate 301. At this time, the upper arc plate 303 will be driven downward by the threaded rod 306. When the upper arc plate 303 moves downward, the first supporting spring 304 and the second supporting spring 307 are compressed. The distance between the upper arc plate 303 and the lower arc plate 301 is reduced, and the first pipe fitting 4 is automatically clamped. When the threaded rod 306 is reversed, the rotating wheel 305 will move upward. At this time, the second pipe fitting 6 will be automatically loosened, and the welded first pipe fitting 4 and the second pipe fitting 6 can be removed. The first supporting spring 304 and the second supporting spring 307 are both located between the lower arc plate 301 and the upper arc plate 303, so that the upper arc plate 303 can be reset and moved upward when the threaded rod 306 is reversed.

[0038] Reference Figure 8 and Fig. 9 The feeding mechanism 5 includes a connecting box 501 for support, a sliding groove is provided at the top of the connecting box 501, a fixing plate 502 is fixedly connected to the side of the connecting box 501 away from the second pipe fitting 6 in the sliding groove, the fixing plate 502 is fixedly connected to the side of the second pipe fitting 6 close to the second pipe fitting 6, the limiting cylinder 503 is movably connected to the limiting rod 504 inside the limiting cylinder 503 away from the fixing plate 502, a placing block 506 is fixedly connected to the side of the limiting rod 504 away from the limiting cylinder 503, a return spring 505 is movably sleeved on the side of the limiting cylinder 503 and the limiting rod 504, the placing block 506 is fixedly connected to the limiting plate 507 on the side away from the limiting rod 504, a placing groove adapted to the second pipe fitting 6 is provided inside the placing block 506, and a through hole adapted to the second pipe fitting 6 is provided inside the limiting plate 507.

[0039] In the embodiment of the present application, when the placement block 506 and the limit plate 507 are moved toward the direction of the fixed plate 502, the second pipe fitting 6 can be placed in the placement groove of the placement block 506 and the through hole of the limit plate 507. In this state, the position of the second pipe fitting 6 will be limited to ensure that the second pipe fitting 6 is in an aligned state when connected to the first pipe fitting 4. The reset spring 505 is also in a pre-stressed state when it is away from the fixed plate 502, ensuring that the second pipe fitting 6 can be sent to the specified position, and the placement block 506 and the limit plate 507 can be moved close to the fixed plate 502 to facilitate loading work and avoid the second pipe fitting 6 from contacting the welding gun 7 during loading and damaging the welding gun 7.

[0040] The working principle of the present invention is as follows: before welding, the placing block 506 and the limiting plate 507 are moved toward the direction of the fixed plate 502, and the placing block 506 and the limiting plate 507 will compress the reset spring 505 when they move. After the placing block 506 and the limiting plate 507 are moved, the second pipe fitting 6 is placed in the placing groove of the placing block 506 and the through hole of the limiting plate 507. After the placing block 506 and the limiting plate 507 are released, the reset spring 505 is reset and drives the placing block 506 and the limiting plate 507 to move. When the placing block 506 and the limiting plate 507 move, the side of the second pipe fitting 6 away from the fixed plate 502 is pushed to the bottom of the welding gun 7, completing the loading work of the second pipe fitting 6. After the loading work state of the second pipe fitting 6 is completed, as shown in FIG. Figure 8 As shown, at this time, the return spring 505 is also in a pre-stressed state, ensuring that the placement block 506 and the limit plate 507 can push the second pipe 6 to the bottom of the welding gun 7;

[0041] When the loading work of the second pipe fitting 6 is completed, the first pipe fitting 4 is placed between the lower arc plate 301 and the upper arc plate 303, and the first pipe fitting 4 is moved above the lower arc plate 301 so that the side surface of the first pipe fitting 4 contacts the side surface of the second pipe fitting 6. When the two contact, the contact surface is directly below the welding gun 7. At this time, the threaded rod 306 is rotated, and the threaded rod 306 drives the rotating wheel 305 to rotate. When the rotating wheel 305 rotates, it will move downward in the lower arc plate 301. At this time, the threaded rod 306 drives the upper arc plate 303 to move downward. When the upper arc plate 303 moves downward, it compresses the first support spring 304 and the second support spring 307, and the distance between the upper arc plate 303 and the lower arc plate 301 is reduced, and the first pipe fitting 4 is automatically clamped;

[0042] When the first pipe 4 is clamped and the first pipe 4 contacts the second pipe 6, the welding machine body 8 controls the welding gun 7 to perform welding. At this time, the welding gun 7 welds the first pipe 4 and the second pipe 6 at the position directly above the second pipe 6. The first pipe 4 and the second pipe 6 are welded together. At this time, the servo motor 201 is started. After the servo motor 201 is started, the output shaft 202 is driven to rotate. When the output shaft 202 rotates, the output gear 203 drives the rotating gear 204 to rotate. When the rotating gear 204 rotates, the clamping mechanism 3 is driven to rotate as a whole through the connecting rod 206. When the clamping mechanism 3 rotates, it drives the first pipe 4 to rotate. The first pipe 4 and the second pipe 6 have been welded together. Therefore, when the first pipe 4 rotates, it will automatically drive the second pipe. 6 rotates, automatically performing the welding work of the first pipe fitting 4 and the second pipe fitting 6, and when the output shaft 202 rotates, it drives the first bevel gear 207 to rotate on the other hand, and when the first bevel gear 207 rotates, it drives the synchronous gear 210 to rotate through the second bevel gear 208 and the transmission of the speed-increasing gear set 209, and when the synchronous gear 210 rotates, it drives the rotating shaft 212 to rotate through the transmission gear 211, and the rotating shaft 212 drives the eccentric rod 213 above it to rotate, and when the eccentric rod 213 rotates, the reciprocating plate 214 reciprocates along the axial direction of the fixed shaft 215, and when the reciprocating plate 214 reciprocates, it drives the welding gun 7 to reciprocate, so when the first pipe fitting 4 and the second pipe fitting 6 rotate, the welding gun 7 will reciprocate at the welding position to ensure the welding quality;

[0043] After the connection between the first pipe fitting 4 and the second pipe fitting 6 is welded for one circle, the servo motor 201 is turned off, and the welding machine body 8 controls the welding gun 7 to be turned off. At this time, the threaded rod 306 is rotated in the opposite direction to move the rotating wheel 305 upward. When the rotating wheel 305 moves upward, the compressed first supporting spring 304 and the second supporting spring 307 will be reset, so that the upper arc plate 303 moves upward to release the first pipe fitting 4. When the first pipe fitting 4 is removed, the second pipe fitting 6 will be removed synchronously to complete the welding work.

[0044] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
