[0023] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1 - 6As shown in the figure, a welding device for narrow spaces includes a base 1; a support column 2 is fixedly connected to the top end of the outer wall of the base 1, and the support column 2 is in a loop shape; a square shell 3 is slidably connected to the inner side wall of the support column 2; a square plate 4 is slidably connected to the inner side wall of the square shell 3; a welding torch 5 is fixedly connected to the bottom end of the outer wall of the square plate 4; an adjusting member is provided at the top end of the outer wall of the support column 2; the adjusting member includes a second motor 6; a threaded groove 7 is formed on one side of the outer wall of the square plate 4; a first motor 8 is fixedly connected to one side of the outer wall of the square shell 3 through a pair of fixing blocks; a threaded rotating shaft 9 is provided at the output end of the first motor 8; one end of the outer wall of the threaded rotating shaft 9 penetrates through one side of the outer wall of the square shell 3 and is located in the threaded groove 7, and the threaded rotating shaft 9 is threadedly connected to the threaded groove 7. By driving the threaded rotating shaft 9 to rotate through the first motor 8, since the threaded rotating shaft 9 is threadedly connected to the threaded groove 7 on the square plate 4, the rotation of the threaded rotating shaft 9 will drive the square plate 4 to slide in the square shell 3, and the movement of the square plate 4 will drive the welding torch 5 to move, so that the welding torch 5 moves in a straight line, thereby welding the place where the belt conveyor drive frame needs to be welded, making the device not require manual welding in the inner space of the belt conveyor drive frame, so that the device is not only relatively convenient for welding, but also has high efficiency and high welding quality.
[0025] A square plate 4 is fixedly connected with a placement shell 13 through a connecting block at the bottom end of the outer wall outside the square shell 3, and the placement shell 13 is matched with the welding torch 5; a square through groove 14 is opened at the top end of the outer wall of the placement shell 13; a sliding block 15 is slidably connected to the inner side wall of the square through groove 14, and the bottom end of the outer wall of the sliding block 15 is slidably connected to the bottom end of the inner wall of the placement shell 13; one side of the outer wall of the connecting block is rotatably connected with a first threaded rod 16, and one end of the outer wall of the first threaded rod 16 penetrates through the sliding block 15, and the first threaded rod 16 is threadedly connected with the sliding block 15; the bottom end of the outer wall of the square shell 3 is rotatably connected with a connecting rod 17 through a connecting plate, and one end of the outer wall of the connecting rod 17 is circular and the other end of the outer wall is square; a first square groove 18 is opened at one end of the outer wall of the first threaded rod 16, and the square-shaped outer wall end of the connecting rod 17 is slidably connected to the inner side wall of the first square groove 18; sprockets 19 are fixedly connected to the outer wall ends of one end of the connecting rod 17 and the outer side wall of the end of the threaded rotating shaft 9 that does not penetrate through the square shell 3, and a pair of sprockets 19 are connected by a chain 20. When the first motor 8 drives the threaded rotating shaft 9 to rotate and the welding torch 5 moves in a straight line for welding, first place the welding wire into the placement shell 13 and press against the sliding block 15. When the first motor 8 drives the threaded rotating shaft 9 to rotate, the rotation of the threaded rotating shaft 9 will drive the connecting rod 17 to rotate through the sprocket 19 and the chain 20. Since the square-shaped outer wall end of the connecting rod 17 is slidably connected to the inner side wall of the first square groove 18 on the first threaded rod 16, the rotation of the connecting rod 17 will drive the first threaded rod 16 to rotate. Since the first threaded rod 16 is threadedly connected with the sliding block 15, the rotation of the first threaded rod 16 will drive the sliding block 15 to move. The movement of the sliding block 15 will slowly extrude the welding wire out of the placement shell 13, so that when the welding torch 5 moves in a straight line for welding, the movement of the sliding block 15 will make the welding wire slowly move towards the position of the welding torch 5, achieving the effect of automatic wire feeding, without pause during the period, and the weld seam is completed in one go. Because there is no need for manual wire feeding operation, the welding of this device is more convenient and the operation is simpler. Moreover, the movement of the square plate 4 driving the welding torch 5 will drive the placement shell 13 to move through the connecting block, achieving synchronous wire feeding operation, making it not easy to have errors in wire feeding. And when the first threaded rod 16 moves, it will make the connecting rod 17 move in the first square groove 18 on the first threaded rod 16. Since the connecting rod 17 does not break away from the first threaded rod 16, the first threaded rod 16 will move following the placement shell 13 and rotate through the connecting rod 17 at the same time, so that the device will not malfunction during operation.
[0026] On one side of the outer wall of the placement shell 13, a first through groove 21 is provided; on one side of the outer wall of the sliding block 15, an adjusting block 22 is fixedly connected, and the outer side wall of the adjusting block 22 is slidably connected to the inner side wall of the first through groove 21; the inner side wall of the placement shell 13 is slidably connected with a placement block 23; on one side of the outer wall of the placement block 23, a moving block 24 is fixedly connected, and the outer side wall of the moving block 24 is slidably connected to the inner side wall of the first through groove 21; on one side of the outer wall of the moving block 24, a second threaded rod 25 is rotatably connected, and one end of the outer wall of the second threaded rod 25 penetrates through the adjusting block 22, and the second threaded rod 25 is threadedly connected with the adjusting block 22. By rotating the second threaded rod 25, because the second threaded rod 25 is threadedly connected with the adjusting block 22, when the first threaded rod 16 rotates, the second threaded rod 25 will move. The movement of the second threaded rod 25 will drive the moving block 24 to move, and the movement of the moving block 24 will drive the placement block 23 to move. Thus, the distance between the placement block 23 and the sliding block 15 can be adjusted, so that when welding is carried out, it can abut against the placement block 23. Then, by driving the second threaded rod 25, the adjusting block 22 and the moving block 24 to move through the sliding block 15, the placement block 23 is driven to move, achieving automatic wire feeding. And because the distance between the placement block 23 and the sliding block 15 can be adjusted, the position of the placement block 23 can be adjusted by this device. When the welding torch 5 performs welding operations, the welding wire can reach a suitable position, making the welding wire not easy to waste. At the same time, when the welding torch 5 performs welding, the welding wire can reach a certain position for welding, so that when the welding torch 5 performs welding, it is not easy for the welding wire not to reach the position, thus avoiding welding defects. And this device can also be adjusted according to the length of the welding wire, so that the welding wire can be replaced for welding operations.
[0027] At the bottom end of the outer wall of the second motor 6, it is fixedly connected to the top end of the outer wall of the support column 2; at the output end of the second motor 6, there is a threaded rotating rod 10, and the bottom end of the outer wall of the threaded rotating rod 10 penetrates through the top end of the outer wall of the support column 2 and the square shell 3, and the threaded rotating shaft 9 is threadedly connected with the square shell 3; on one side of the outer wall of the support column 2, a storage box 11 is fixedly connected; on the top end of the outer wall of the storage box 11, a group of round holes 12 are provided. By driving the threaded rotating rod 10 to rotate through the second motor 6, because the threaded rotating rod 10 is threadedly connected with the square shell 3, the rotation of the threaded rotating rod 10 drives the square shell 3 to move to a suitable position, so that the square shell 3 drives the square plate 4 and the welding torch 5 to move to a suitable height, thus facilitating the position of the welding torch 5 in this device according to the height of the position to be welded on the belt conveyor drive frame. Thus, when this device is welding, it is not only more convenient, and when the position of the welding torch 5 is adjusted to a certain position, the welding effect and quality can be further improved. And because on one side of the outer wall of the support column 2, a storage box 11 is fixedly connected; on the top end of the outer wall of the storage box 11, a group of round holes 12 are provided, when this device performs welding operations, the welding wire can be placed in the storage box 11, making it more convenient to take the welding wire. And through the round holes 12 on the storage box 11, the welding wire can be placed neatly, making it more convenient to take and place the welding wire.
[0028] One side of the outer wall of the placing block 23 is fixedly connected with a fixing plate 26; one side of the outer wall of the placing block 23 is slidably connected with a clamping plate 27; one side of the outer wall of the fixing plate 26 is rotatably connected with a third threaded rod 28, and one end of the outer wall of the third threaded rod 28 penetrates through the clamping plate 27, and the third threaded rod 28 is threadedly connected with the clamping plate 27; both the clamping plate 27 and the fixing plate 26 are located in the square through groove 14; arc grooves 29 are formed on the opposite sides of the outer walls of the clamping plate 27 and the fixing plate 26; one end of the outer wall of the placing shell 13 is fixedly connected with a guiding tube 30, and the guiding tube 30 is matched with the welding torch 5. When the welding wire is placed in the placing shell 13, since it is necessary to press the welding wire against the placing block 23 to make the welding wire contact with the placing block 23, at this time, the third threaded rod 28 is rotated. Because the third threaded rod 28 is threadedly connected with the clamping plate 27, the rotation of the third threaded rod 28 will cause the clamping plate 27 to move towards the fixing plate 26, so that the clamping plate 27 cooperates with the fixing plate 26 to clamp and fix the welding wire, making the welding operation of the welding wire more stable, thus ensuring the quality of the welding of the belt conveyor drive frame. And because one end of the outer wall of the placing shell 13 is fixedly connected with the guiding tube 30, the welding wire can be placed through the guiding tube 30 when placed. When the welding wire is automatically fed, it will also move out through the guiding tube 30, ensuring that the position of the welding wire is not easily offset during the automatic wire feeding operation, making the welding of the belt conveyor drive frame more stable and not prone to errors.
[0029] Working principle: When the device is welding the inner space of the belt conveyor drive frame, first, the second motor 6 drives the threaded rotating rod 10 to rotate. Since the threaded rotating rod 10 is threadedly connected to the square shell 3, the rotation of the threaded rotating rod 10 drives the square shell 3 to move to a suitable position, so that the square shell 3 drives the square plate 4 and the welding torch 5 to move to a suitable height, thus facilitating the position adjustment of the welding torch 5 in the device according to the height of the welding position required by the belt conveyor drive frame. Therefore, when the device is welding, it is not only more convenient, but also when the position of the welding torch 5 is adjusted to a certain position, the welding effect and quality can be further improved. When the welding torch 5 moves to a suitable height, the first motor 8 drives the threaded rotating shaft 9 to rotate. Since the threaded rotating shaft 9 is threadedly connected to the threaded groove 7 on the square plate 4, the rotation of the threaded rotating shaft 9 will drive the square plate 4 to slide within the square shell 3. The movement of the square plate 4 will drive the welding torch 5 to move, making the welding torch 5 move in a straight line, so as to weld the place that needs to be welded on the belt conveyor drive frame. This enables the device to weld without manual operation inside the inner space of the belt conveyor drive frame, making the device not only more convenient for welding, but also with higher efficiency and better welding quality. And when the first motor 8 drives the threaded rotating shaft 9 to rotate and the welding torch 5 moves in a straight line for welding, first place the welding wire in the placement shell 13 and press against the sliding block 15. When the first motor 8 drives the threaded rotating shaft 9 to rotate, the rotation of the threaded rotating shaft 9 will drive the connecting rod 17 to rotate through the sprocket 19 and the chain 20. Since one end of the square-shaped outer wall of the connecting rod 17 is slidably connected to the inner side wall of the first square groove 18 on the first threaded rod 16, the rotation of the connecting rod 17 will drive the first threaded rod 16 to rotate. Since the first threaded rod 16 is threadedly connected to the sliding block 15, the rotation of the first threaded rod 16 will drive the sliding block 15 to move, and the movement of the sliding block 15 will slowly extrude the welding wire from the placement shell 13. When the welding torch 5 moves in a straight line for welding, the movement of the sliding block 15 will make the welding wire slowly move towards the position of the welding torch 5, achieving the effect of automatic wire feeding without pause and the weld seam being completed in one go. Since there is no need for manual wire feeding operation, the device is more convenient and easier to operate during welding. And the movement of the square plate 4 driving the welding torch 5 will drive the placement shell 13 to move through the connecting block, achieving synchronous wire feeding operation, making it less likely for wire feeding to have errors. And when the first threaded rod 16 moves, the connecting rod 17 will move in the first square groove 18 on the first threaded rod 16. Since the connecting rod 17 does not disengage from the first threaded rod 16, the first threaded rod 16 moves along with the placement shell 13 and rotates through the connecting rod 17, ensuring that the device will not malfunction during operation. And on one side of the outer wall of the support column 2, there is a storage box 11 fixedly connected;A set of round holes 12 are provided at the top end of the outer wall of the storage box 11. When welding operations are performed on this device, the welding wire can be placed in the storage box 11, making it more convenient to pick up the welding wire. Moreover, through the round holes 12 on the storage box 11, the welding wire can be neatly placed, making it more convenient to pick up and place the welding wire. By rotating the second threaded rod 25, since the second threaded rod 25 is threadedly connected to the adjustment block 22, when the first threaded rod 16 rotates, the second threaded rod 25 will move. The movement of the second threaded rod 25 will drive the movement block 24 to move, and the movement of the movement block 24 will drive the placement block 23 to move, thereby adjusting the distance between the placement block 23 and the sliding block 15. When welding, it can abut against the placement block 23. Then, the sliding block 15 drives the second threaded rod 25, the adjustment block 22, and the movement block 24 to move, driving the placement block 23 to move, achieving automatic wire feeding. And since the distance between the placement block 23 and the sliding block 15 can be adjusted, this device can adjust the position of the placement block 23 so that when the welding torch 5 performs welding operations, the welding wire can reach the appropriate position, making the welding wire not easily wasted. At the same time, when the welding torch 5 performs welding, the welding wire can reach a certain position for welding, so that when the welding torch 5 performs welding, it is not easy for the welding wire not to reach the position, thus avoiding welding defects. Moreover, this device can also be adjusted according to the length of the welding wire, enabling the welding wire to be replaced for welding operations. When the welding wire is placed in the placement shell 13, since it is necessary to abut the welding wire against the placement block 23 and make the welding wire contact the placement block 23, at this time, rotate the third threaded rod 28. Since the third threaded rod 28 is threadedly connected to the clamping plate 27, the rotation of the third threaded rod 28 will cause the clamping plate 27 to move towards the fixed plate 26, making the clamping plate 27 cooperate with the fixed plate 26 to clamp and fix the welding wire, making the welding wire more stable during welding operations, thereby ensuring the quality of the welding of the belt conveyor drive frame. And since a guide tube 30 is fixedly connected to one end of the outer wall of the placement shell 13, the welding wire can be placed through the guide tube 30 when placed, and when the welding wire is automatically fed, it will also move out through the guide tube 30, ensuring that the position of the welding wire is not easily offset during the automatic wire feeding operation, making the welding of the belt conveyor drive frame more stable and not prone to errors.
