[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0018] Example 1, as Figure 1 As shown, a welding fixture for a combustion torch includes a worktable 5, on which a positioner 6 is mounted. A support plate 1 is connected to an mounting plate 601 installed at the output end of the positioner 6, thereby allowing the positioner 6 to drive the support plate 1 to rotate. A moving device 4 is mounted on the worktable 5 and moves relative to it, with the support plate 1 located between the positioner 6 and the moving device 4. A clamping unit 2 and an adjusting device 3 are mounted on the support plate 1. The adjusting device 3 includes a horizontal adjusting unit 301 and a vertical adjusting unit 302, both of which are connected to the support plate 1. The support plate 1 supports the torch head, and the horizontal adjusting unit 301 drives the clamping unit. 2. The support plate 1 moves relative to the vertical adjustment unit 302, which drives the support plate 1 to slide relative to the mounting plate 601. The part of the torch head to be welded is clamped by the clamping unit 2. The horizontal adjustment unit 301 and the vertical adjustment unit 302 are used to adjust the horizontal and vertical positions of the torch head so that when the moving device 4 moves the torch tube to the part of the torch head to be welded, the gap between the torch tube and the torch head is uniform, which can ensure the positional accuracy between the torch head and the torch tube. For torch heads and torch tubes of different types and sizes, the horizontal adjustment unit 301 and the vertical adjustment unit 302 can be used for adjustment, which can save time in finding suitable tooling and improve welding efficiency.

[0019] like Figure 2As shown, specifically, the clamping unit 2 includes a mounting base 201 slidably connected to the support plate 1. The mounting base 201 is provided with a pressure rod 202 that opens and closes relative to it. When clamping the torch head, the mounting base 201 and the pressure rod 202 are relatively closed, forming a first mounting space 203. The mounting base 201 and the support plate 1 have a slider-rail structure, which is existing technology and will not be described in detail here. The mounting base 201 and the pressure rod 202 have a sliding fit or a rotational fit, preferably a rotational fit, when clamping the torch head. When the torch head is clamped, one end of the pressure rod 202 is rotatably connected to one side of the mounting base 201, and the other end of the pressure rod 202 is located between the pressure block 204 and the other side of the mounting base 201. The position of the pressure rod 202 is locked by the locking device. When the torch head does not need to be clamped, one end of the pressure rod 202 is still rotatably connected to one side of the mounting base 201, but the other end of the pressure rod 202 is no longer located between the pressure block 204 and the other side of the mounting base 201, and the locking device no longer locks the position of the pressure rod 202.

[0020] Specifically, the locking device preferably uses a screw threadedly connected to the pressure block 204 to lock the position of the pressure rod 202. The pressure block 204 is rotatably connected to the mounting base 201, and the pressure block 204 is located on one side of the groove in the mounting base 201. A first screw 205 is provided between the pressure block 204 and the mounting base 201, and the first screw 205 is threadedly connected to the pressure block 204. When clamping the torch head, the torch head is placed in the groove of the mounting base 201, and then the pressure rod 202 is rotated, so that one end of the pressure rod 202 rotates with one side of the groove in the mounting base 201. The other end of the pressure rod 202 contacts the other side of the groove of the mounting base 201, and this side is the side connected to the pressure block 204. The pressure block 204 is flipped longitudinally so that the pressure rod 202 is located between the mounting base 201 and the pressure block 204. The pressure block 204 is rotated, and through the first screw 205, the pressure block 204 presses the pressure rod 202 onto the mounting base 201. At this time, a first installation space 203 is formed between the pressure rod 202 and the mounting base 201, and the torch head is located in the first installation space 203 formed by the closing of the pressure rod 202 and the mounting base 201.

[0021] like Figure 3 As shown, specifically, the horizontal adjustment unit 301 is used to drive the mounting base 201 to slide relative to the support plate 1. The horizontal adjustment unit 301 includes a second screw 311 and a second screw sleeve 312 used in conjunction with the second screw 311. The second screw sleeve 312 is disposed on the support plate 1. One end of the second screw 311 passes through the second screw sleeve 312 and is rotatably connected to the mounting base 201. When adjusting the horizontal position of the torch head, a wrench, screwdriver, or other tool capable of rotating the screw is selected to rotate the second screw 311. The second screw 311 passes through the second screw sleeve 312 and pushes the mounting base 201, causing the mounting base 201 to slide relative to the support plate 1, and adjusts to a suitable horizontal position according to the position of the torch tube.

[0022] like Figure 4 As shown, specifically, the vertical adjustment unit 302 includes a third screw 321, a third screw sleeve 322 used in conjunction with the third screw 321, and a receiving plate 323. The third screw sleeve 322 is fixedly connected to the mounting plate 601, and the receiving plate 323 is connected to the support plate 1. The receiving plate 323 can move relative to the third screw sleeve 322 along the axial direction of the third screw 321. The receiving plate 323 and the support plate 1 are fixedly connected by screws. One end of the third screw 321 passes through the third screw sleeve 322 and is fixedly connected to the receiving plate 323. When adjusting the vertical position of the torch head, use a wrench, screwdriver, or other tool capable of rotating the screw to turn the third screw 321. The third screw 321 passes through the third screw 321 and drives the receiving plate 323, causing the receiving plate 323 to push the support plate 1 vertically upward or downward. After adjusting the horizontal position of the torch head according to the position of the torch tube, adjust the vertical position of the torch head to ensure that the gap between the torch tube and the torch head is uniform, thus ensuring the positional accuracy between the torch head and the torch tube.

[0023] like Figure 3 As shown, the mounting plate 601 is further provided with a shock absorber 7, which is used to support the torch head. The shock absorber 7 can absorb shock when the torch head is placed on the support plate 1, thus protecting the torch head and welding fixture.

[0024] like Figure 3 As shown, the mounting plate 601 is further provided with support columns 8, which are slidably connected to the mounting plate 601 and in contact with the torch head. There are two support columns 8, which are located on both sides of the torch head respectively, and can form a three-point positioning with the support plate 1 to improve the structural stability of the welding fixture. The support columns 8 are slidably connected to the mounting plate 601, and can adjust the support position according to different types of torch heads to improve the adaptability of the welding fixture.

[0025] Example 2, based on Example 1, describes the specific structure of the moving device 4. The moving device 4 includes a first moving unit 401 and a second moving unit 402. The first moving unit 401 is located between the second moving unit 402 and the support plate 1. Both the first moving unit 401 and the second moving unit 402 are slidably connected to the worktable 5. The first moving unit 401 and the second moving unit 402 are connected to the worktable 5 via a slider-rail structure. The slider-rail structure is within the scope of existing technology and will not be described in detail here. See [link to relevant documentation] for details. Figure 1 . Furthermore, both the first moving unit 401 and the second moving unit 402 are equipped with a fourth screw 403. One end of the fourth screw 403 is in close contact with the worktable 5 through the first moving unit 401, thereby limiting the position of the first moving unit 401. The second moving unit 402 is also limited in position by the fourth screw 403. After the torch tube is moved to the appropriate position, the first moving unit 401 and the second moving unit 402 can be locked to prevent slippage and make welding inconvenient.

[0026] like Figure 1 As shown, furthermore, limit posts 501 are provided at both ends of the workbench 5, which can prevent the first moving unit 401 and the second moving unit 402 from slipping off the slide rail when adjusting their positions, thus increasing the time for subsequent repairs, reducing efficiency, and improving the stability of the welding fixture. In addition, the limit posts 501 near the positioner 6 can ensure that the torch tube is just located at the welding point of the torch head, preventing the torch tube from moving excessively and colliding with the torch head, causing damage to the torch head, and improving the stability of the welding fixture.

[0027] like Figure 7 As shown, specifically, the moving unit 401 includes a housing 411 slidably connected to the worktable 5. The housing 411 is provided with a first support wheel 412 and a pressing wheel 413 that contact the flare tube, with the pressing wheel 413 located above the first support wheel 412. Two first support wheels 412 are provided and located on opposite sides of the flare tube. Each first support wheel 412 is connected to the output end of a cylinder 415, which is located inside the housing 411. The first support wheels 412 can move between the housing 411 and the flare tube. Similarly, two pressing wheels 413 are provided and located on opposite sides of the flare tube. On both sides of the flare tube, cylinder 416 extends upward from one side of housing 411. The output end of cylinder 416 is connected to one end of a lever 417, and the other end of lever 417 is connected to one end of a connecting rod 418. A fixed seat 419 is installed on the other end of connecting rod 418, and two pressure wheels 413 are mounted on the fixed seat 419. A groove 405 is provided on housing 411, allowing lever 417 to contact the side of the groove 405. Both the output end of cylinder 416 and lever 417 are connected to one end of a limiting rod 404, and the other end of the limiting rod 404 is connected to housing 411. Figure 4 and Figure 5As shown, when the flare tube does not need to be pressed, the output end of cylinder 2 416 retracts, driving the power rod 417 to rotate within the groove 405. When one side of the power rod 417 contacts the side of the groove 405, the power rod 417 drives the connecting rod 418 to rise, causing the pressing wheel 413 to move away from the flare tube. When the pressing wheel 413 reaches a certain position, the limit rod 404 limits the distance between the output end of cylinder 2 416 and the housing 1 411, and the pressing wheel 413 stops moving. At the same time, cylinder 1 415... The output end retracts, causing the first support wheel 412 to move away from the flare tube; when it is necessary to press the flare tube, the output ends of cylinder one 415 and cylinder two 416 extend, and the pressing wheel 413 and the first support wheel 412 gradually approach the flare tube until the pressing wheel 413 presses the flare tube onto the first support wheel 412, forming a second installation space 414 between the pressing wheel 413 and the first support wheel 412, and the flare tube is located in the second installation space 414 formed by the first support wheel 412 and the pressing wheel 413.

[0028] like Figure 8 As shown, specifically, the second moving unit 402 includes a second housing 421 that is slidably connected to the worktable 5. The second housing 421 is provided with a second support wheel 422 that contacts the torch tube. There are two second support wheels 422, which are located on both sides of the torch tube respectively, to provide more stable support.

[0029] like Figure 5 As shown, further, a housing 406 is detachably connected to the side of the housing 411 opposite to the positioner 6. The housing 406 is connected to the housing 411 by screws. The housing 406 is provided with a gourd-shaped through hole 461. The screw passes through the small hole of the gourd-shaped through hole 461 and is fixedly connected to the housing 411. To remove the housing 406, the housing 406 is lifted so that the screw is located in the large hole of the gourd-shaped through hole 461. The large hole of the gourd-shaped through hole 461 is larger than the screw. The end diameter is large, and the end of the screw can pass through the large hole of the gourd-shaped through hole 461 to remove the housing 406. To install the housing 406, first pass the screw through the large hole of the gourd-shaped through hole 461. The large hole of the gourd-shaped through hole 461 is located between the end of the screw and the housing 411. Then, move the housing 406 down so that the screw is located in the small hole of the gourd-shaped through hole 461. The installation is complete. Welding waste is collected to prevent it from falling into the shelf.

[0030] Working principle: When adjusting the position: first place the torch head on the support plate 1, clamp the part of the torch head to be welded by the clamping unit 2, place the torch tube on the moving device 4, determine the position of the torch tube, and then adjust the radial position of the torch head by the cooperation of the horizontal adjustment unit 301 and the vertical adjustment unit 302 until the gap between the torch tube and the torch head is uniform. During welding: First, spot welding is performed on the part of the torch to be welded along the circumference to fix the position of the torch head and the torch tube. Then, the first support wheel 412 and the pressure wheel 413 are moved away from the torch tube by cylinder 1 415 and cylinder 2 416 respectively. At this time, the torch tube is only positioned by three points and the moving unit 2 402 to position the two ends of the torch tube. The workers weld the gap between the torch head and the torch tube. The positioner 6 rotates the torch head, which drives the torch tube to rotate, making it easier for the workers to weld. After welding is completed, the next process is carried out.
