Description

Technical Field

[0001] The present invention belongs to the technical field of metal pipe clamp welding, and specifically relates to a metal pipe clamp processing and welding device. Background Art

[0002] A metal pipe clamp is a device used to fix and connect pipes, mainly composed of metal clips and bolts. During the production process of metal pipe clamps, in order to enhance the connection stability and durability, the bolts are welded to the metal clips. This welding method can ensure that the bolts will not loosen or fall off during use, thus effectively fixing the pipes.

[0003] A patent application with the publication number CN115383272A discloses an automatic bolt welding device, including a projection welder and a bolt conveyor. Inside the bolt conveyor, there are a bolt conveyor, a bolt delivery pipe, and a bolt pushing gun. A fixed joint is arranged at one end of the bolt delivery pipe close to the bolt pushing gun. While improving the service life of the lower electrode of the projection welder, the compressed air that pushes the bolt out of the pallet is the compressed air used to convey the next bolt in the bolt delivery pipe, eliminating the need for an additional air source, improving the utilization rate of compressed air, reducing air source waste, and saving energy.

[0004] However, there are still some problems in the actual application of the above solution. When welding metal clips and bolts with the above device, the bolts need to be passed through the holes on the surface of the metal clips, and then the contact parts between the bolts and the metal clips are welded. However, due to the large number of welding parts each time, if continuous automatic welding cannot be achieved, it will greatly affect the working cycle. Although the metal clips are in a regular sheet shape and can be continuously conveyed by stacking, the bolts cannot be stacked, and when welding, the bolts need to be accurately inserted into the metal clips. At this time, the placement position of the bolts needs to be manually adjusted before welding, which is very cumbersome.

[0005] Therefore, the present invention provides a metal pipe clamp processing and welding device. Summary of the Invention

A welding platform is provided at the upper end of the base frame. A conveying structure is provided on the surface of the welding platform. A welding structure is provided at the upper end of the conveying structure. The welding structure includes a welding head. The conveying structure includes: a placement table provided on the surface of the welding platform; a sliding block slidably connected to the surface of the placement table; a welding groove opened on the surface of the placement table; a feeding frame provided at the upper end of the placement table; a rotating table rotatably connected inside the feeding frame, and a temporary storage platform is provided on the upper surface of the rotating table; a blocking strip provided on the outer wall of the rotating table; a conveying track provided at one end of the rotating table, and the conveying track is flush with the temporary storage platform; a placement rod provided at the lower end of the end of the conveying track; a dropping cylinder provided inside the feeding frame near one end of the placement rod.

[0009] Preferably, a second rotating shaft is rotatably connected to one end of the feeding frame near the placement rod, and a dial is provided at the upper end of the second rotating shaft.

[0010] Preferably, a first rotating shaft is provided at the lower end of the rotating table, a connecting track is sleeved on the surface of the first rotating shaft, and the other end of the connecting track is sleeved on the surface of the second rotating shaft.

[0011] Preferably, the surface of the dial is arc-shaped.

[0012] Preferably, a limiting plate is provided at one end of the upper surface of the blocking strip near the conveying track.

[0013] Preferably, a sliding strip is provided at the lower end of the feeding frame, a blocking door is slidably connected inside the sliding strip, and the blocking door is located at the lower end of the dropping cylinder in the initial state, and the blocking door abuts against the sliding block.

[0014] Preferably, both ends of the sliding block are rotatably connected to a third rotating shaft, the surface of the third rotating shaft is sleeved with a second coil spring, the surface of the third rotating shaft is provided with a fixed plate, the interior of the fixed plate is slidably connected with a sliding plate, an adjusting spring is provided between the fixed plate and the sliding plate, an abutment roller is provided between the two sliding plates, and buckles are provided at one end of the two ends of the sliding block close to the third rotating shaft, and the buckles abut against the fixed plate.

[0015] Preferably, a return spring is provided inside the sliding bar, and one end of the return spring is connected to the blocking door.

[0016] Preferably, a plurality of placement plates are rotatably connected inside the sliding block, and first coil springs are provided at both ends of the placement plates.

[0017] The beneficial effects of the present invention are as follows: 1. A metal pipe clamp processing and welding device described in the present invention, by setting a feeding frame, when performing welding work on the clamp and the bolt, a plurality of bolts are placed inside the rotating table, and the rotating table is started to rotate. Through the action of centrifugal force and the limiting of the blocking bar, the bolts will be arranged in sequence on the surface of the temporary storage platform, and as the rotating table rotates, the bolts will fall on the surface of the conveyor crawler and be sent to the surface of the placement rod through the conveyor crawler for placement. Under the influence of gravity, the heavier end of the bolt will face downward, and because the placement rod is inclined, as the paddle is moved, the bolt will be pushed to the upper end of the drop tube and fall into the inside of the drop tube, so that the bolts can be automatically sorted and transferred to the inside of the sliding block for welding.

[0018] 2. A metal pipe clamp processing and welding device described in the present invention, by setting a placement plate, when the bolt is transferred to the inside of the sliding block, it will fall on the surface of the placement plate for temporary storage. At this time, the first coil springs at both ends of the placement plate will prevent the placement plate from rotating significantly. Then the welding head moves downward and presses the bolt into the hole of the clip. Since the pressure of the welding head is too high, the placement plate will rotate at this time, so that the bolt will fall into the hole of the clip. By using the placement plate to temporarily store the bolt inside the sliding block, the friction between the bolt and the sliding block can be reduced, thereby increasing the service life of both.

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] Embodiment 1 As Figures 1 to 11As shown in the figure, a metal pipe clamp processing and welding device according to an embodiment of the present invention includes a base frame 1. A welding platform 2 is provided at the upper end of the base frame 1. A conveying structure 4 is provided on the surface of the welding platform 2. A welding structure 3 is provided at the upper end of the conveying structure 4. The welding structure 3 includes a welding head 34. The conveying structure 4 includes: a placing table 401, which is provided on the surface of the welding platform 2; a sliding block 404, which is slidably connected to the surface of the placing table 401; a welding groove 411, which is opened on the surface of the placing table 401; a feeding frame 402, which is provided at the upper end of the placing table 401; a rotating table 408, which is rotatably connected to the inside of the feeding frame 402, and a temporary storage platform 409 is provided on the upper end surface of the rotating table 408; a blocking strip 405, which is provided on the outer wall of the rotating table 408; a conveying track 410, which is provided at one end of the rotating table 408, and the conveying track 410 is flush with the temporary storage platform 409; a placing rod 406, which is provided at the lower end of the end of the conveying track 410; a dropping cylinder 413, which is provided at one end of the inside of the feeding frame 402 close to the placing rod 406.

[0023] Specifically, a metal pipe clamp processing and welding device of this solution is mainly used for processing and welding metal pipe clamps. The metal pipe clamp is mainly composed of a clip 5 and a bolt 6. During processing and welding, first place the clip 5 on the surface of the welding platform 2, and then pass the bolt 6 through the hole on the surface of the clip 5 so that the washer of the bolt 6 contacts the clip 5. At this time, start the welding structure 3 located above the clip 5. The welding method of this welding structure 3 is resistance welding, specifically spot welding. At this time, the welding head 34 will move downward. When the welding head 34 contacts the washer at the end of the bolt 6, energize the welding head 34 to make the current pass through the washer at the end of the bolt 6. Due to the existence of resistance, heat will be generated when the current passes through, causing the contact part between the washer and the clip 5 to heat up and melt to form a fusion nucleus. After the fusion nucleus is formed, cut off the power supply of the welding head 34 and maintain the pressure for a period of time to make the fusion nucleus cool and solidify under the action of pressure to form a solder joint. At this time, the welding of the metal pipe clamp is completed. However, this welding method not only cannot perform continuous and automatic welding, but also requires accurately passing the bolt 6 through the hole on the surface of the clip 5 before each welding, which is very cumbersome. Therefore, a conveying structure 4 is set up. When welding, first pour several bolts 6 into the inside of the rotating table 408, place the clip 5 on the surface of the welding groove 411, and then start the rotating table 408 to rotate. During the rotation of the rotating table 408, it will drive the bolt 6 to rotate together. And under the action of centrifugal force, the bolt 6 will be thrown onto the surface of the temporary storage platform 409. And the width of the temporary storage platform 409 is only limited to the stay of one bolt 6. With the limit of the blocking strip 405, the bolts 6 will be arranged in sequence on the surface of the temporary storage platform 409. When the rotating table 408 rotates one circle, the bolt 6 will be transferred to the surface of the conveying track 410. Then start the conveying track 410, and the conveying track 410 will transfer the bolt 6 to the surface of the placing rod 406. The gap between the placing rods 406 can pass through the threaded end of the bolt 6, but cannot pass through the larger end of the bolt 6. And affected by gravity, the threaded end of the bolt 6 will face downward. Since the placing rod 406 is inclined towards the dropping cylinder 413, the bolt 6 located on the surface of the placing rod 406 will fall into the inside of the dropping cylinder 413 at this time and enter the inside of the sliding block 404 through the dropping cylinder 413. At this time, start the sliding block 404, and the bolt 6 can be transferred to directly above the clip 5. At this time, start the welding head 34, and the welding head 34 will move downward. Since the bolt 6 is stuck inside the sliding block 404 and the welding head 34 is directly above the clip 5, at this time the welding head 34 will press the bolt 6 into the hole of the clip 5. At this time, energize the welding head 34 again to complete the processing and welding of the metal pipe clamp. By setting up the conveying structure 4, the bolts 6 can be automatically sorted and continuously fed, thereby improving the processing and welding efficiency.

[0024] Such as Figures 1 to 7As shown, the welding structure 3 further includes: a fixing frame 31 disposed at the upper end of the welding platform 2; a telescopic cylinder 32 disposed at the upper end of the fixing frame 31; a connecting plate 33 disposed at the lower end of the telescopic cylinder 32, and the connecting plate 33 is connected to the welding head 34; the conveying structure 4 further includes: a slide rail 403 disposed on the surface of the placing table 401, and a sliding block 404 slides on the surface of the slide rail 403; a blanking port 407 disposed at the upper end of the material conveying frame 402.

[0025] Specifically, when processing and welding the metal pipe clamp, first pour a plurality of bolts 6 into the inside of the rotating table 408 through the blanking port 407. Subsequently, when the bolts 6 are transferred to the inside of the sliding block 404, start the sliding block 404, and the sliding block 404 will slide on the surface of the slide rail 403. Then, when the bolts 6 are pressed into the holes of the clip 5, start the telescopic cylinder 32, and the telescopic cylinder 32 will drive the welding head 34 to move through the connecting plate 33, thereby performing the welding work.

[0026] As Figures 1 to 7 shown, a second rotating shaft 416 is rotatably connected to one end of the inside of the material conveying frame 402 close to the placing rod 406, and a dial 417 is provided at the upper end of the second rotating shaft 416.

[0027] Specifically, by providing the dial 417, when the bolts 6 fall on the surface of the placing rod 406, start the second rotating shaft 416, and the second rotating shaft 416 will drive the dial 417 to rotate. The dial 417 will push the bolts 6 towards the dropping cylinder 413, thereby more quickly realizing the transfer of the bolts 6.

[0028] As Figure 7 shown, a first rotating shaft 414 is provided at the lower end of the rotating table 408, a connecting track 415 is sleeved on the surface of the first rotating shaft 414, and the other end of the connecting track 415 is sleeved on the surface of the second rotating shaft 416.

[0029] Specifically, by providing the first rotating shaft 414, when the rotating table 408 rotates, the connecting track 415 can be driven to rotate through the first rotating shaft 414. And since the other end of the connecting track 415 is sleeved on the surface of the second rotating shaft 416, the second rotating shaft 416 will also rotate at this time, thereby performing the transfer of the bolts 6.

[0030] As Figure 7 shown, the surface of the dial 417 is arc-shaped.

[0031] Specifically, by setting the contact surface between the dial 417 and the bolts 6 to be arc-shaped, when the dial 417 contacts the bolts 6, the arc-shaped surface can make the dial 417 contact the bolts 6 more fully, thereby pushing the bolts 6.

[0032] As shown Figures 1 to 6 in FIG. 1, a limiting plate 412 is provided at one end of the upper surface of the blocking bar 405 close to the conveying track 410.

[0033] Specifically, by providing the limiting plate 412, when the bolt 6 is conveyed on the surface of the temporary storage platform 409, the limiting plate 412 can ensure that each screw lies flat on the surface of the temporary storage platform 409, and then falls on the surface of the conveying track 410 for conveying.

[0034] Embodiment 2 As shown Figures 8 to 11 in FIG. 2, compared with Embodiment 1, another implementation manner of the present invention is that a sliding bar 418 is provided at the lower end of the material feeding frame 402, a blocking door 419 is slidably connected inside the sliding bar 418, and the blocking door 419 is located at the lower end of the dropping cylinder 413 in the initial state, and the blocking door 419 abuts against the sliding block 404.

[0035] Specifically, by providing the blocking door 419, when the bolt 6 is transferred to the inside of the dropping cylinder 413, the bolt 6 will fall on the upper surface of the blocking door 419. At this time, only after the sliding block 404 moves and pushes open the blocking door 419, the bolt 6 will pass through the blocking door 419 and fall into the inside of the sliding block 404, thereby avoiding the phenomenon that the bolt 6 drops without the sliding block 404 moving directly below the bolt 6.

[0036] As shown Figures 8 to 11 in FIG. 3, both ends of the sliding block 404 are rotatably connected with a third rotating shaft 424. A second coil spring 425 is sleeved on the surface of the third rotating shaft 424. A fixing plate 426 is provided on the surface of the third rotating shaft 424. A sliding plate 428 is slidably connected inside the fixing plate 426. An adjusting spring 429 is provided between the fixing plate 426 and the sliding plate 428. A contact roller 427 is provided between the two sliding plates 428. A buckling member 423 is provided at one end of both ends of the sliding block 404 close to the third rotating shaft 424, and the buckling member 423 abuts against the fixing plate 426.

[0037] Specifically, by providing the contact roller 427, when the sliding block 404 moves to the lower end of the material feeding frame 402, the contact roller 427 will contact the blocking door 419, and during the movement of the sliding block 404, since the contact roller 427 is in contact with the blocking door 419 all the time, the sliding plate 428 will move towards the inside of the fixing plate 426 at this time, so as to adaptively adjust the distance between the contact roller 427 and the blocking door 419. Subsequently, during the abutting process, the fixing plate 426 will rotate around the third rotating shaft 424 as the axis. Subsequently, when the fixing plate 426 rotates to contact the buckling member 423, the contact roller 427 will push open the blocking door 419, so that the bolt 6 falls into the inside of the sliding block 404.

[0038] As Figure 9 shown, a return spring 420 is provided inside the slider 418, and one end of the return spring 420 is connected to the blocking door 419.

[0039] Specifically, by setting the return spring 420, when the bolt 6 is transferred to be connected to the clip 5, the slider 404 will be reset. At this time, when there is no abutment of the abutting roller 427, the return spring 420 will release elastic force, and finally drive the blocking door 419 to be reset.

[0040] As Figures 8 to 11 shown, a plurality of placing plates 422 are rotatably connected inside the slider 404, and first torsion springs 421 are provided at both ends of the placing plate 422.

[0041] Specifically, when the bolt 6 is transferred into the slider 404, it will be temporarily stored on the surface of the placing plate 422. At this time, the first torsion springs 421 at both ends of the placing plate 422 will prevent the placing plate 422 from rotating significantly. Subsequently, when the welding head 34 moves downward and presses the bolt 6 into the hole of the clip 5, due to the excessive pressure of the welding head 34, the placing plate 422 will rotate at this time, so that the bolt 6 falls into the hole of the clip 5. By using the placing plate 422 to temporarily store the bolt 6 inside the slider 404, the friction between the bolt 6 and the slider 404 can be reduced, and the service life of both can be increased.

[0042] Working principle: During processing and welding, first pour several bolts 6 into the interior of the rotating table 408, place the clamping piece 5 on the surface of the welding groove 411, then start the rotation of the rotating table 408. During the rotation of the rotating table 408, the bolts 6 will be driven to rotate together, and under the action of centrifugal force, the bolts 6 will be thrown onto the surface of the temporary storage platform 409. The width of the temporary storage platform 409 is only limited to the stay of one bolt 6. With the limit of the blocking strip 405, the bolts 6 will be arranged in sequence on the surface of the temporary storage platform 409. When the rotating table 408 rotates one circle, the bolts 6 will be transferred to the surface of the conveying track 410. Then start the conveying track 410, and the conveying track 410 will transfer the bolts 6 to the surface of the placing rod 406. The gap between the placing rods 406 allows the threaded end of the bolt 6 to pass through, but the larger end of the bolt 6 cannot pass through. And affected by gravity, the threaded end of the bolt 6 will face downwards. Since the placing rod 406 is inclined towards the dropping cylinder 413, the bolts 6 located on the surface of the placing rod 406 will fall into the interior of the dropping cylinder 413 at this time. At this time, the bolts 6 will fall on the upper surface of the blocking door 419. Start the sliding block 404, and the sliding block 404 will slide on the surface of the slide rail 403. When the sliding block 404 moves to the lower end of the material feeding frame 402, the abutting roller 427 will come into contact with the blocking door 419. And during the movement of the sliding block 404, since the abutting roller 427 is in contact with the blocking door 419 all the time, the sliding plate 428 will move towards the interior of the fixed plate 426 at this time, so as to adaptively adjust the distance between the abutting roller 427 and the blocking door 419. Then during the abutting process, the fixed plate 426 will rotate around the third rotating shaft 424 as the axis. Then when the fixed plate 426 rotates to contact the buckling 423, the abutting roller 427 will push open the blocking door 419, so that the bolts 6 fall into the interior of the sliding block 404. Then the sliding block 404 transfers the bolts 6 to directly above the clamping piece 5. At this time, start the welding head 34, and the welding head 34 will move downwards. Since the bolts 6 are stuck in the interior of the sliding block 404, the welding head 34 will press the bolts 6 into the holes of the clamping piece 5 at this time. Energize the welding head 34 to make the current pass through the washer at the end of the bolt 6. Due to the existence of resistance, heat will be generated when the current passes through, so that the contact part between the washer and the clamping piece 5 is heated and melted to form a fusion core. After the fusion core is formed, cut off the power supply of the welding head 34 and maintain the pressure for a period of time, so that the fusion core cools and solidifies under the action of pressure to form a solder joint. At this time, the welding of the metal pipe clamp is completed.
