Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and is particularly related to a welding torch holder. Background Technology

[0002] During the welding of corrugated pipe joints, the welding torch needs to be fixed directly above the area to be welded using a bracket. The corrugated pipe and joint are then rotated during welding to complete the welding of the entire contact area. With existing torch brackets, the torch position is difficult to adjust after fixing, requiring the torch height to be adjusted using a screw before the welded corrugated pipe joint and joint can be removed. This process is time-consuming, therefore an improvement is necessary. Utility Model Content

[0003] To address the aforementioned deficiencies in the prior art, this application provides a welding torch holder that allows the welding torch to rotate after being fixed, and automatically resets after being lowered, facilitating the removal of the welded corrugated pipe joint and corrugated pipe.

[0004] To achieve the above objectives, the present invention employs the following technology: A welding torch holder, comprising: A vertical rod has its top circumference rotatably connected to one end of a horizontal rod. A limit ring is coaxially connected to the horizontal rod, and a limit block is provided around the limit ring. A first connecting plate is provided at the top of the vertical rod. One side of the first connecting plate protrudes from the side of the vertical rod near the limit ring. A vertically arranged limit screw is threaded onto the first connecting plate, and the bottom of the limit screw is within the rotation range of the limit block. The slider is slidably connected to the crossbar along the length of the crossbar. The slider is threaded with a first locking screw. When the first locking screw is tightened, the first locking screw abuts against the crossbar. The mounting base is used to mount the welding torch. The mounting base is connected to the slider via a connecting rod. When the limit block rotates to abut the limit screw, the connecting rod is in an inclined state.

[0005] Furthermore, a strip groove is provided around the crossbar, with the length direction of the strip groove parallel to the length direction of the crossbar. A through hole is provided on the slider, penetrating both sides of the slider. A slider is provided in the through hole, and the slider is slidably connected to the strip groove.

[0006] Furthermore, when the first locking screw is tightened, the first locking screw is located in the slot, and the bottom of the first locking screw abuts against the bottom wall of the slot.

[0007] Furthermore, the connecting rod is perpendicular to the crossbar, and the connecting rod is slidably connected to the slider, with the sliding direction of the connecting rod parallel to its own length direction.

[0008] Furthermore, a second locking screw is threaded onto one side of the slider. When the second locking screw is tightened, it abuts against the connecting rod.

[0009] Furthermore, the top of the connecting rod extends through the top of the slider and connects to a second connecting plate. A second adjusting screw parallel to the slider is rotatably connected to the second connecting plate. The slider has a second threaded hole that passes through its top and bottom, and the second adjusting screw is threaded into the second threaded hole.

[0010] Furthermore, a third connecting plate is provided at the end of the crossbar away from the vertical bar. A third adjusting screw parallel to the crossbar is rotatably connected to the third connecting plate. A third threaded hole is provided on the slider, penetrating both sides therethrough. The third adjusting screw is threadedly connected to the third threaded hole.

[0011] Furthermore, the vertical rod is vertically mounted on a support platform, and the bottom of the support platform has an upward-facing connection hole. A fixing screw is installed in the connection hole, and the fixing screw is threadedly connected to the bottom of the vertical rod.

[0012] The beneficial effects of this utility model are as follows: 1. After welding is completed, lift the welding torch upwards and rotate the crossbar to avoid the welded bellows joint and bellows, making it easier to remove the bellows joint and bellows. Finally, lower the welding torch. Because the bottom of the limit screw will continue to block the limit block, the welding torch will automatically reset due to its own gravity. 2. The position of the connecting rod can be adjusted by tightening or loosening the second locking screw, thereby adjusting the height of the welding torch to accommodate the welding of bellows joints of various sizes.

Detailed Implementation

[0020] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0021] This application provides a welding torch holder, such as... Figures 1-6 As shown, it includes a vertical rod 1, a slider 4, a mounting base 5, etc.

[0022] Specifically, the top of the periphery of the vertical rod 1 is rotatably connected to one end of a horizontal rod 2. A limit ring 3 is coaxially connected to the horizontal rod 2, and a limit block 301 is provided around the periphery of the limit ring 3. A first connecting plate 102 is provided at the top of the vertical rod 1. One side of the first connecting plate 102 protrudes from the side of the vertical rod 1 near the limit ring 3. A vertically arranged limit screw 103 is threaded on the first connecting plate 102, and the bottom of the limit screw 103 is within the rotation range of the limit block 301. A slider 4 is slidably connected to the horizontal rod 2 along the length direction of the horizontal rod 2. A first locking screw 403 is threaded on the slider 4. When the first locking screw 403 is tightened, the first locking screw 403 abuts against the horizontal rod 2. A mounting base 5 is used to install a welding torch 6. The mounting base 5 is connected to the slider 4 through a connecting rod 501. When the limit block 301 rotates to abut against the limit screw 103, the connecting rod 501 is in an inclined state.

[0023] In actual use, the vertical rod 1 can be fixed to the welding workbench, and the welding torch 6 can be fixed to the mounting base 5. The height of the bottom of the limit screw 103 can be adjusted by turning the limit screw 103 upward, so that the limit block 301 can rotate within a certain range, thereby allowing the connecting rod 501 to rotate with the horizontal bar 2 to adjust the height of the bottom of the welding torch 6. The welding fixture for the corrugated pipe joint is placed below the welding torch 6. Then, the slider 4 is slid to align the welding torch 6 with the fixed corrugated pipe joint, and the first locking screw 403 is tightened to start welding. After welding is completed, the welding torch 6 is lifted upward, and the horizontal bar 2 is rotated to avoid the completed corrugated pipe joint and corrugated pipe, making it easy to remove the corrugated pipe joint and corrugated pipe. Finally, when the welding torch 6 is lowered, because the bottom of the limit screw 103 will continue to block the limit block 301, the welding torch 6 will automatically reset due to its own gravity.

[0024] For details, please refer to Figure 2 , Figure 3 , Figure 5 A strip groove 201 is formed around the periphery of the crossbar 2, with its length parallel to the length direction of the crossbar 2. A through hole 401 is formed on both sides of the slider 4, and a sliding strip 402 is installed within the through hole 401. The sliding strip 402 is slidably connected to the strip groove 201, thus allowing the slider 4 to move only along the length direction of the crossbar 2 and preventing it from rotating on the crossbar 2. More specifically, when the first locking screw 403 is tightened, it is positioned within the strip groove 201, and its bottom abuts against the bottom wall of the strip groove 201. This design increases the contact area between the bottom of the first locking screw 403 and the crossbar 2, improving the stability of the slider 4 after tightening.

[0025] Preferred options, please refer to Figure 5 , Figure 6 The connecting rod 501 is perpendicular to the crossbar 2 and is slidably connected to the slider 4. The sliding direction of the connecting rod 501 is parallel to its own length. Specifically, a second locking screw 406 is threaded onto one side of the slider 4. When the second locking screw 406 is tightened, it abuts against the connecting rod 501. With this setting, the position of the connecting rod 501 can be adjusted by tightening or loosening the second locking screw 406, thereby adjusting the height of the welding torch 6 to accommodate the welding of bellows joints of various sizes.

[0026] Preferred options, please refer to Figure 5 The top of the connecting rod 501 extends through the top of the slider 4 and connects to a second connecting plate 404. A second adjusting screw 405, parallel to the slider, is rotatably connected to the second connecting plate 404. The slider 4 has a second threaded hole penetrating its top and bottom, and the second adjusting screw 405 is threaded into the second threaded hole. By turning the second adjusting screw 405, the connecting rod 501 can be slowly moved along its axial direction, facilitating fine adjustments to the height of the welding torch 6. Specifically, a retaining ring can be provided around the second adjusting screw 405, so that the retaining ring abuts against the side of the second connecting plate 404 near the connecting rod 501, achieving a rotatable connection between the second adjusting screw 405 and the second connecting plate 404.

[0027] Preferred options, please refer to Figure 5 A third connecting plate 202 is provided at the end of the horizontal bar 2 away from the vertical bar 1. A third adjusting screw 203 parallel to the horizontal bar 2 is rotatably connected to the third connecting plate 202. A third threaded hole is provided on both sides of the slider 4, and the third adjusting screw 203 is threaded into the third threaded hole. By turning the third adjusting screw 203, the slider 4 can be moved slowly along the horizontal bar 2, which facilitates fine adjustment of the position of the slider 4.

[0028] Specifically, a retaining ring can also be provided around the third adjusting screw 203, so that the retaining ring abuts against the side of the third connecting plate 202 near the crossbar 2, thereby realizing the rotational connection between the third adjusting screw 203 and the third connecting plate 202.

[0029] For details, please refer to Figure 1 , Figure 4 The vertical rod 1 is vertically mounted on a support platform 7. The bottom of the support platform 7 has an upward-facing connection hole, and a fixing screw 104 is installed in the connection hole. The fixing screw 104 is threaded to the bottom of the vertical rod 1 for easy assembly.
