Description

Technical Field

[0001] This utility model relates to a welding device, and more particularly to a welding device for a fabric chute. Background Technology

[0002] As is well known, the welding device for fabric chutes is an auxiliary device used to repair damaged areas on the inner surface of fabric chutes by welding, and it has been widely used in the field of welding repair.

[0003] For example, a welding device for a fabric chute, disclosed in Chinese Patent Publication No. CN209936179U, includes a welding torch containing welding wire; it also includes a left support plate, a right support plate, a horizontal plate, a left rotating rod, a right rotating rod, a first turntable, a first threaded rod, a limiting rod, a slider, a telescopic rod, a spring, a fixing plate, a fixing pin, a roller, a left connecting plate, a right connecting plate, a top plate, and an arc-shaped plate. A square hole is longitudinally arranged in the central area of ​​the top of the horizontal plate. Left and right rotating holes are transversely arranged in the front half of the left and right sides of the horizontal plate, respectively. A first threaded hole and a sliding hole are transversely arranged in the front and rear half of the left side of the slider, respectively. A fixing hole is longitudinally arranged in the central area of ​​the top of the fixing plate. It also includes a second left threaded rod, a second right threaded rod, a second left turntable, a second right turntable, a left pressure plate, and a right pressure plate.

[0004] Some problems have been found in the use of the existing welding device for fabric chutes. First, the welding rod will gradually wear down and shorten during the welding process. Especially in the surfacing process, multiple welding rods are often required. After the welding rods are shortened, the end of the welding rod cannot make contact with the position to be welded. Second, the gaps and holes to be welded are often small. After the welding rod is aligned with the gap to be welded in advance, when the fabric chutes are clamped and fixed, the fabric chutes may shift slightly, which may cause the hole and the welding rod to be misaligned, requiring multiple readjustments. Utility Model Content

[0005] The purpose of this invention is to provide a welding device for fabric chutes to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding device for a fabric chute, comprising a connecting frame and a fabric chute. A connecting groove is provided within the connecting frame, and a supporting horizontal plate is slidably installed within the connecting groove. First limiting grooves are symmetrically provided on the left and right sides within the supporting horizontal plate. A first limiting slider is slidably installed within the first limiting groove. A clamping plate is fixedly connected below the first limiting slider. A motor bracket is fixedly connected to the front end of the connecting frame, and a reciprocating motor is fixedly connected below the motor bracket. A reciprocating vertical plate is fixedly connected to the output end of the reciprocating motor. A second limiting groove is provided on the front side of the reciprocating vertical plate, and a second limiting slider is slidably installed within the second limiting groove. A clamping collar is fixedly connected to the front side of the second limiting slider, and a welding gun is sleeved within the clamping collar. A welding rod is connected to the lower end of the welding gun.

[0007] Preferably, a bidirectional threaded rod is rotatably installed inside the supporting cross plate, and a rotating disk is fixedly connected to one end of the bidirectional threaded rod. A first threaded through hole is opened in the first limiting slider, and the first threaded through hole is threadedly engaged with the bidirectional threaded rod.

[0008] Preferably, the support cross plate has limit slots on both the upper and lower surfaces, and the connecting groove has convex rails fixedly connected to both the upper and lower surfaces, with the convex rails slidingly engaging with the limit slots.

[0009] Preferably, a first threaded sleeve block is embedded behind the connecting frame, and a first threaded fine-tuning column is rotatably installed behind the supporting cross plate, the first threaded fine-tuning column being threadedly engaged with the first threaded sleeve block.

[0010] Preferably, a threaded adjusting screw is rotatably installed in the second limiting slide groove, and a conveying motor is fixedly connected to the reciprocating vertical plate, with the output end of the conveying motor fixedly connected to the threaded adjusting screw.

[0011] Preferably, the second limiting slider has a second threaded through hole, which is threadedly engaged with the threaded adjusting screw. The clamping collar has a second threaded sleeve block embedded on its front side, and a compression bolt is installed in the inner thread of the second threaded sleeve block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By starting the conveyor motor, the clamping collar can be moved downward. The downward movement of the clamping collar will also move the welding gun downward. After the lower end of the welding rod is consumed, the downward movement of the welding gun can be controlled in time to ensure that the lower end of the welding rod is always in contact with the material chute. This avoids the problem that the lower end of the welding rod cannot continue to build up the welding operation because it is consumed and cannot contact the material chute.

[0014] 2. By using a rotating disk to drive the bidirectional threaded rod to rotate, the clamping plate clamps and fixes both sides of the fabric chute, roughly aligning the welding rod with the welding position. Later, the first threaded fine-tuning column is rotated to move the connecting frame and fine-tune the welding rod. This avoids the problem of the welding rod not being aligned with the welding position inside the fabric chute due to slight misalignment of the clamping device, which would require repeated device adjustments.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a welding device for a fabric chute, including a connecting frame 3 and a fabric chute 7. The connecting frame 3 has a connecting groove 302, and a supporting horizontal plate 1 is slidably installed in the connecting groove 302. The supporting horizontal plate 1 has symmetrically opened first limiting grooves 101, and a first limiting slider 201 is slidably installed in the first limiting groove 101. A clamping plate 2 is fixedly connected to the lower part of the first limiting slider 201. A motor bracket 301 is fixedly connected to the front end of the connecting frame 3. A reciprocating motor 4 is fixedly connected to the lower part of the motor bracket 301. A reciprocating vertical plate 401 is fixedly connected to the output end of the reciprocating motor 4. A second limiting groove 402 is opened on the front side of the reciprocating vertical plate 401, and a second limiting slider 503 is slidably installed in the second limiting groove 402. A clamping collar 5 is fixedly connected to the front side of the second limiting slider 503. A welding gun 6 is sleeved in the clamping collar 5, and a welding rod 601 is connected to the lower end of the welding gun 6.

[0022] In this embodiment, by utilizing the sliding engagement of the first limiting slider 201 and the first limiting groove 101, the clamping plate 2 is slidably installed under the supporting horizontal plate 1. The two clamping plates 2 are used to clamp the two sides of the fabric chute 7, fixing the supporting horizontal plate 1 onto the fabric chute 7. The supporting horizontal plate 1 is slidably installed inside the connecting groove 302, allowing the connecting frame 3 to move back and forth relative to the supporting horizontal plate 1. The movement of the connecting frame 3 can be achieved by the reciprocating motor 4 driving the welding gun 6 to move. The movement of the welding gun 6 will drive the welding rod 601 to move, thereby fine-tuning the position of the welding rod 601. Align the welding position with the desired location, start the reciprocating motor 4 to drive the reciprocating vertical plate 401 to rotate back and forth, making the reciprocating motor 4 swing like a pendulum. The welding gun 6 is connected to the welding machine via a cable. The welding gun 6 is used to perform welding operations inside the fabric chute 7. The second limit slider 503 slides and engages with the second limit groove 402, so that the clamping collar 5 can move up and down relative to the reciprocating motor 4. As the end of the welding rod 601 is used up, the clamping collar 5 drives the welding gun 6 to move down. The downward movement of the welding gun 6 will also move the welding rod 601 down, so that the lower end of the welding rod 601 can always contact the welding position.

[0023] To achieve the purpose of clamping and fixing the device on the fabric chute 7, the device adopts the following technical solution: a bidirectional threaded rod 102 is rotatably installed inside the supporting horizontal plate 1, and a rotating disk 103 is fixedly connected to one end of the bidirectional threaded rod 102. A first threaded through hole 202 is opened in the first limiting slider 201, and the first threaded through hole 202 is threadedly engaged with the bidirectional threaded rod 102. Limiting slots 104 are opened on both the upper and lower surfaces of the supporting horizontal plate 1. A convex rail 304 is fixedly connected to both the upper and lower surfaces of the connecting slide 302, and the convex rail 304 is slidably engaged with the limiting slot 104. A first threaded sleeve block 303 is embedded and installed behind the connecting frame 3. A first threaded fine adjustment column 105 is rotatably installed behind the supporting horizontal plate 1, and the first threaded fine adjustment column 105 is threadedly engaged with the first threaded sleeve block 303.

[0024] The rotating disk 103 can drive the bidirectional threaded rod 102 to rotate. The bidirectional threaded rod 102 is threadedly engaged with the first threaded through hole 202. The rotation of the bidirectional threaded rod 102 can drive the first limiting slider 201 to move. The movement of the first limiting slider 201 can drive the clamping plate 2 to move, thereby adjusting the distance between the two clamping plates 2. The clamping plates 2 are used to clamp the fabric chute 7 on both sides. The first threaded fine-tuning column 105 is threadedly engaged with the first threaded sleeve block 303. Rotating the first threaded fine-tuning column 105 can drive the connecting frame 3 to move back and forth, thereby fine-tuning the back and forth position of the welding rod 601.

[0025] To achieve the purpose of adjusting the position of the welding torch 6, the device adopts the following technical solution: a threaded adjusting screw 403 is rotatably installed in the second limiting slide groove 402; a conveying motor 404 is fixedly connected to the reciprocating vertical plate 401; the output end of the conveying motor 404 is fixedly connected to the threaded adjusting screw 403; a second threaded through hole 504 is opened in the second limiting slider 503; the second threaded through hole 504 is threadedly engaged with the threaded adjusting screw 403; a second threaded sleeve block 501 is embedded in the front of the clamping collar 5; and a pressing bolt 502 is threadedly installed in the second threaded sleeve block 501.

[0026] By starting the conveyor motor 404, the threaded adjusting screw 403 can be rotated. The threaded adjusting screw 403 is threadedly engaged with the second threaded through hole 504. The rotation of the threaded adjusting screw 403 can drive the second limiting slider 503 to move. The movement of the second limiting slider 503 can drive the clamping ring 5 to move. In turn, the clamping ring 5 drives the welding torch 6 to move up and down. The welding torch 6 is sleeved inside the clamping ring 5. Tightening the extrusion bolt 502 will cause its end to contact the surface of the welding torch 6, thereby fixing the welding torch 6 to the clamping ring 5.

[0027] The working principle and usage process of this utility model are as follows: The support plate 1 is placed on the fabric chute 7. First, the welding rod 601 is roughly aligned with the position to be welded within the fabric chute 7. The rotating disk 103 drives the bidirectional threaded rod 102 to rotate, causing the clamping plate 2 to hold and fix both sides of the fabric chute 7, thus fixing the support plate 1 on the fabric chute 7. Then, the connecting frame 3 connected to the first threaded fine-tuning column 105 is rotated and moved. The movement of the connecting frame 3 causes the welding gun 6 to move, thereby fine-tuning the position of the welding rod 601. The reciprocating motor 4 is controlled by an electric control system to rotate back and forth. The reciprocating motor 4 can drive the reciprocating vertical plate 401 to rotate. The reciprocating vertical plate 401 drives the welding gun 6 to rotate through the clamping collar 5, so that the welding rod 601 moves back and forth at the position to be welded for the welding operation. Starting the conveyor motor 404 can drive the clamping collar 5 to move down. The downward movement of the clamping collar 5 will drive the welding gun 6 to move down, so that after the lower end of the welding rod 601 is consumed, the downward movement of the welding gun 6 can be controlled in time to keep the lower end of the welding rod 601 in contact with the material chute 7.
