[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1 Reference Figure 1 and Figure 4This is the first embodiment of the present invention. This embodiment provides an auxiliary component for welding heat dissipation fins. The auxiliary component for welding heat dissipation fins includes a welding assembly 100 and a clamping assembly 200. The welding assembly 100 is used to facilitate welding operations on finned tubes, and the clamping assembly 200 is used to clamp finned tubes, thereby further improving processing efficiency.

[0028] Specifically, the welding assembly 100 includes a worktable 101, support legs 102, a fixed plate 103, a movable plate 104, a clamping tube 105, a guide tube 106, a moving part 107, a welding part 108, and a rotating part 109. The support legs 102 are fixed to the four corners of the bottom of the worktable 101, the fixed plate 103 is fixed to one side of the top of the worktable 101, the movable plate 104 slides on the other side of the top of the worktable 101, the clamping tube 105 is rotatably connected to the fixed plate 103 and the movable plate 104, the guide tube 106 is fixed to the end of the clamping tube 105, the moving part 107 is disposed on the top of the worktable 101, the welding part 108 is disposed between the fixed plate 103 and the movable plate 104, and the rotating part 109 is disposed on the worktable 101 and cooperates with the clamping tube 105.

[0029] The bottom of the support leg 102 is fixed with an anti-slip pad to improve the stability of the device during use. The movable plate 104 can move left and right through the movable part 107, which facilitates the clamping operation of finned tubes of different lengths. The guide tube 106 is trumpet-shaped. When installing the finned tube, it can be placed in the guide tube 106 first, so that it can be placed in the clamping tube 105 more conveniently and effortlessly. The clamping tube 105 is connected to the fixed plate 103 and the movable plate 104 through bearings, so that the clamping tube 105 can rotate during welding. The welding part 108 is used to hold the welding torch and makes it easier to move the welding torch left and right to operate on any position on the finned tube. At the same time, the rotating part 109 allows the operator to rotate the finned tube by stepping on it, without manual rotation, which greatly improves the welding efficiency.

[0030] The clamping assembly 200, disposed within the clamping tube 105, includes a rotating plate 201, an arc-shaped plate 202, a connector 203, a movable disc 204, a first spring 205, a lifting member 206, a top plate 207, and fasteners 208. The clamping tube 105 has evenly distributed mounting grooves S. The rotating plate 201 is rotatably connected to the mounting grooves S. The arc-shaped plate 202 is disposed at the end of the rotating plate 201. The connector 203 is disposed on the outer side of the arc-shaped plate 202. The movable disc 204 slides within the clamping tube 105. The two ends of the first spring 205 are respectively fixed to the movable disc 204 and the inner wall of the clamping tube 105. The lifting member 206 is disposed on the movable disc 204. The top plate 207 is fixed to the inner wall of the clamping tube 105. The fasteners 208 are disposed on the surface of the clamping tube 105.

[0031] The rotating plate 201 is rotatably connected to the mounting groove S via a shaft. Four rotating plates 201 are provided in the mounting groove S, evenly distributed in a ring on the clamping tube 105. The arc-shaped plate 202 can fit the finned tube, and the connecting piece 203 allows the arc-shaped plate 202 to rotate when clamping the finned tube, thus making its inner side fit the finned tube more closely and improving clamping stability. Anti-slip pads and barbs are fixed to the inner side of the arc-shaped plate 202 to increase the friction between it and the finned tube, thereby further improving its stability. Qualitatively, four top plates 207 are provided, evenly distributed in a ring on the side of the inner wall of the clamping tube 105. The movable disk 204 has corresponding grooves, thus forming a push ring on the inner side of the four top plates 207. When the movable disk 204 moves outward, the push ring pushes the ends of the four top plates 207 to expand outward, thereby making them fit against the inner wall of the finned tube, further improving the stability of the finned tube installation from the inside. In addition, rubber blocks are fixed on the top plates 207 to increase the friction between them and the finned tube.

[0032] The first spring 205 applies an outward force to the movable plate 204. When the finned tube is pulled out of the clamping tube 105, the first spring 205 pushes the movable plate 204 to move outward along with the finned tube. At this time, the top plate 207 has a restoring elastic force, thus separating from the finned tube. At the same time, during the outward movement of the movable plate 204, the lifting member 206 pushes the rotating plate 201 outward, so that the arc plate 202 separates from the finned tube, thus completing the reset operation and preventing the arc plate 202 from hindering the subsequent installation of the finned tube. The fastener 208 is used to push and squeeze the rotating plate 201, so that the arc plate 202 can fit more firmly on the finned tube.

[0033] Example 2 Reference Figures 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the movable component 107 includes a receiving plate 107a, a mounting plate 107b, and a threaded rod 107c. The receiving plate 107a is fixed to the top of the workbench 101, the mounting plate 107b is fixed to the right side of the top of the workbench 101, and the threaded rod 107c is rotatably connected between the receiving plate 107a and the mounting plate 107b, and is threadedly connected to the movable plate 104.

[0035] The top of the receiving plate 107a is arc-shaped. When it is necessary to clamp the finned tube, it can be placed on the top of the receiving plate 107a first, which makes it convenient for the staff to install it. When it is necessary to adjust the distance between the movable plate 104 and the fixed plate 103 to accommodate finned tubes of different lengths, the threaded rod 107c is manually rotated. The threaded rod 107c drives the movable plate 104 to move left and right. There are two guide rods fixed between the receiving plate 107a and the mounting plate 107b. They pass through the movable plate 104 and limit and guide the movable plate 104 to prevent it from deviating during left and right movement.

[0036] The welded component 108 includes a connecting block 108a, a sliding rod 108b, a protruding strip 108c, and a movable block 108d. The connecting block 108a is fixed to the side of the fixed plate 103 and the movable plate 104. One end of the sliding rod 108b is fixed to one side of the connecting block 108a, and the other end slides on the other side of the connecting block 108a. The protruding strip 108c is fixed to the side of the sliding rod 108b. The movable block 108d slides on the sliding rod 108b and has an arc-shaped groove K inside it. The protruding strip 108c slides in the arc-shaped groove K.

[0037] The connecting block 108a is rectangular. A hole is provided in the middle of the connecting block 108a on the movable plate 104, and the slide rod 108b can slide in the hole. The other end of the slide rod 108b is fixed to the connecting block 108a on the fixed plate 103. The protrusion 108c is used to limit the movable block 108d. It slides in the arc groove K, so that the movable block 108d can rotate at a certain angle during operation, which makes it convenient for the operator to adjust the welding angle during welding. At the same time, the movable block 108d can slide left and right on the slide rod 108b to adjust the welding position and improve its applicability. The protrusion 108c and the arc groove K are provided with elastic elements to push the movable block 108d to facilitate its reset, so that it is always in a position perpendicular to the finned tube when idle, which makes it convenient to fix the welding gun on the movable block 108d.

[0038] The welding component 108 also includes a clamping plate 108e and an elastic band 108f. The clamping plate 108e is fixed to the top of the movable block 108d, and the elastic band 108f is fixed to the clamping plate 108e.

[0039] The plate 108e is inclined and has an arc-shaped groove on its top. The operator can place the welding gun in the arc-shaped groove and secure it with the elastic band 108f. This allows the operator to adjust the welding position and angle by simply rotating and moving the movable block 108d, without having to hold the welding gun all the time, which greatly improves the welding efficiency.

[0040] The rotating component 109 includes a gear 109a, a toothed plate 109b, a connecting rod 109c, and a fixing rod 109d. The gear 109a is fixed to the end of the clamping tube 105. The toothed plate 109b meshes with the side of the gear 109a. The connecting rod 109c is fixed to one side of the toothed plate 109b. The fixing rod 109d is fixed to the bottom of the connecting rod 109c. A moving groove L is provided on the movable plate 104, and the connecting rod 109c slides in the moving groove L.

[0041] During the welding process, the finned tube needs to rotate. At this time, the fixed rod 109d and the connecting rod 109c can move downward to drive the toothed plate 109b to move downward. During the downward movement, the toothed plate 109b drives the gear 109a to rotate, thereby causing the clamping tube 105 and the finned tube to rotate, which facilitates the operator to perform a circular welding operation. The connecting rod 109c is fixed with limit blocks on both sides of the moving groove L to limit the connecting rod 109c and prevent it from disengaging from the moving groove L, while also preventing it from rotating or shifting during the up and down movement.

[0042] The rotating component 109 also includes a horizontal plate 109e, a footrest 109f, and a second spring 109g. The horizontal plate 109e is fixed to the bottom of the two fixed rods 109d, the footrest 109f is fixed to the bottom of the horizontal plate 109e, and the two ends of the second spring 109g are fixed to the horizontal plate 109e and the worktable 101, respectively.

[0043] The second spring 109g applies an upward force to the horizontal plate 109e and the footrest 109f, facilitating the reset of the toothed plate 109b. During welding, the worker holds the movable block 108d with both hands to adjust its position and angle. While welding, one foot steps down on the footrest 109f, causing the footrest 109f and the horizontal plate 109e to move the fixed rod 109d and the toothed plate 109b downwards. This allows the toothed plate 109b to rotate the gear 109a and the clamping tube 105. The worker no longer needs to manually rotate the finned tube, greatly improving welding convenience and efficiency. After one round of welding, the foot is released from the footrest 109f. The second spring 109g then moves the footrest 109f and the horizontal plate 109e upwards, resetting the toothed plate 109b to its initial position for subsequent welding operations.

[0044] The workbench 101 has a rectangular groove located between the receiving plate 107a and the mounting plate 107b. The fixing rod 109d slides in the groove, so that when the movable plate 104 moves left or right, the fixing rod 109d can move with it. The horizontal plate 109e also has a rectangular groove, and the bottom end of the fixing rod 109d slides in the rectangular groove. At the same time, limit blocks are fixed on the surface of the fixing rod 109d and at the top and bottom of the horizontal plate 109e to prevent the fixing rod 109d from detaching from the rectangular groove on the horizontal plate 109e.

[0045] In use, the finned tube to be welded is installed in the clamping tube 105 on the fixed plate 103. Then, the threaded rod 107c is manually rotated, which drives the movable plate 104 to move left and right, so that the other end of the finned tube is inserted into the clamping tube 105 on the movable plate 104. The welding torch is then fixed to the clamping plate 108e by the elastic band 108f. At this time, the operator can adjust the welding angle and position of the welding torch by moving the connecting block 108a, eliminating the need for the operator to hold the welding torch at all times, thus improving the convenience of processing. During the welding process, the foot pedal 109f is stepped down by one foot, which drives the fixed rod 109d and the toothed plate 109b to move through the foot pedal 109f and the horizontal plate 109e. Moving downwards allows the toothed plate 109b to drive the gear 109a and clamping tube 105 to rotate, eliminating the need for manual rotation of the finned tube and greatly improving welding convenience and efficiency. After one round of welding, the foot is released from the footrest 109f, at which point the second spring 109g drives the footrest 109f and the horizontal plate 109e to move upwards, resetting the toothed plate 109b to its initial position for easy subsequent welding operations. This allows workers to weld damaged areas on the finned tube one round at a time, with more flexible control over the rotation of the finned tube, eliminating the need for additional personnel to rotate the finned tube while welding and greatly improving work efficiency.

[0046] Example 3 Reference Figures 4-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, the connector 203 includes a fixed shaft 203a, a connecting plate 203b, and a stop block 203c. The fixed shaft 203a is fixed to the end of the rotating plate 201, the connecting plate 203b is rotatably connected to both ends of the fixed shaft 203a, and the stop block 203c is fixed on the rotating plate 201.

[0048] The inner side of the connecting plate 203b is fixed to the arc plate 202. The connection plate 203b and the fixed shaft 203a enable the arc plate 202 to rotate, allowing the inner side of the arc plate 202 to rotate at a certain angle, fit against the surface of the finned tube, and limit and fix it, so that it can be used for finned tubes of different diameters. The stop block 203c applies a certain resistance to the rotation of the arc plate 202 to prevent it from moving too far outward, which would affect its rotation and limiting efficiency.

[0049] The lifting component 206 includes a lifting plate 206a and a third spring 206b. A fixing groove M is provided on the movable plate 204. The lifting plate 206a slides in the fixing groove M. The two ends of the third spring 206b are fixed to the inner wall of the fixing groove M and the lifting plate 206a, respectively.

[0050] The lifting plate 206a is subjected to the elastic force of the third spring 206b and has an outward movement force. When the movable plate 204 is pushed to the outside by the first spring 205 to reset, the lifting plate 206a will push the rotating plate 201 outward so that it can enter the mounting groove S in the initial state, preventing it from obstructing the finned tube from entering the clamping tube 105. The lifting plate 206a is fixed with sliders on both sides, and the inner wall of the fixing groove M is provided with a sliding groove. The slider slides in the sliding groove. The two limit the lifting plate 206a to prevent it from deviating during the telescopic movement, and at the same time prevent the lifting plate 206a from detaching from the fixing groove M.

[0051] The fastener 208 includes a threaded ring 208a and a top block 208b. The threaded ring 208a is threadedly connected to the clamping tube 105, and the top block 208b is disposed on one side of the threaded ring 208a.

[0052] The clamping tube 105 has a threaded surface, and the threaded ring 208a is connected to it. When installing the finned tube, the threaded ring 208a is manually rotated to move it outward, and the rotating plate 201 is pushed inward by the top block 208b, so that the arc plate 202 can fit more firmly against the surface of the finned tube. The threaded ring 208a has evenly distributed handles fixed on its surface, which makes it easier for the operator to rotate the threaded ring 208a.

[0053] The fastener 208 also includes a slide rail 208c and a slider 208d. The slide rail 208c is fixed to one side of the threaded ring 208a, and the slider 208d is fixed to the outside of the top block 208b and cooperates with the slide rail 208c.

[0054] The slide rail 208c has a T-shaped cross section, and the slider 208d has a T-shaped groove. The slide rail 208c slides in the groove, so that when the threaded ring 208a rotates, the top block 208b can move left and right with the threaded ring 208a and will not detach from the mounting groove S.

[0055] When performing repair welding on a finned tube, first place one end of the tube into the guide tube 106 on the fixed plate 103, and slowly insert it into the clamping tube 105. During insertion, the movable disc 204 will move inward, and the push ring will push the ends of the four top plates 207 outward, thus fitting them against the inner wall of the finned tube and improving the stability of the finned tube installation from the inside. At the same time, the lifting plate 206a moves to the other side of the rotating plate 201. At this time, manually rotate the threaded ring 208a, which drives the top block 208b to move, and the top block 208b pushes one side of the rotating plate 201 towards... The finned tube is pushed in the direction of the arc plate 202, which fits into the finned tube. The friction and clamping force between the two limit and fix the finned tube, improving its installation stability. Then, the movable plate 104 is moved closer to the fixed plate 103, so that the other end of the finned tube is inserted into the clamping tube 105 on the movable plate 104. The other end of the finned tube is fixed again by the above steps, which makes the installation of the finned tube more convenient and stable. When it is installed stably, it can rotate with the clamping tube 105, and the finned tube will not deviate during the rotation, which greatly improves the stability of the welding process.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
