[0019] Please refer to Figures 1-4 This utility model provides an auxiliary clamp for welding copper pipes of water heaters, including a base plate 1, a horizontal moving mechanism 2, a support seat 3, a bracket 4, a movable rod 5, a spring 6, a connecting seat 7, a rotating device 8, and a clamping wheel 9; The base plate 1 is provided with a receiving groove 11 along the X-axis direction, and the horizontal moving mechanism 2 is disposed in the receiving groove 11; the support base 3 is driven by the driving end of the horizontal moving mechanism 2, so that the support base 3 moves along the X-axis direction; the top of the support base 3 is provided with an arc-shaped groove 301 along the X-axis direction; the bracket 4 is disposed at one end of the support base 3 along the Y-axis direction, the movable rod 5 is slidably assembled on the bracket 4, the upper end of the movable rod 5 is provided with a limiting block 51, and the lower end of the movable rod 5 is connected to the connecting seat 7; the spring 6 is sleeved on the outer periphery of the movable rod 5, the upper end of the spring 6 is tightly abutting against the bracket 4, and the lower end of the spring 6 is tightly abutting against the connecting seat 7; the rotating device 8 is disposed at the bottom of the connecting seat 7; the clamping wheel 9 is driven by the driving end of the rotating device 8, and the clamping wheel 9 is located directly above the arc-shaped groove 301, and the clamping wheel 9 and the arc-shaped groove 301 cooperate to form a copper tube clamping station.

[0020] The base plate 1 provides support and accommodates the horizontal moving mechanism 2. The horizontal moving mechanism 2 drives the copper tube to move horizontally along the X-axis direction via the support seat 3, thereby adjusting the position of the copper tube in the X-axis direction. The limiting block 51 limits the downward movement range of the movable rod 5. The connecting seat 7 connects the movable rod 5 to the rotating device 8. The spring 6 causes the connecting seat 7, the rotating device 8, and the clamping wheel 9 to have a downward tendency, so that they can cooperate with the arc groove 301 to clamp the copper tube and prevent the copper tube from moving during welding. The rotating device 8 drives the clamping wheel 9 to rotate, thereby driving the copper tube to rotate, allowing the copper tube to be rotated and adjusted before welding.

[0021] Before fixing the copper tube, move the connecting seat 7 upward and compress the spring 6, then place the copper tube in the arc groove 301; then, release the connecting seat 7 so that the spring 6 drives the connecting seat 7 to reset, thereby clamping the copper tube; when horizontal adjustment is required, start the horizontal moving mechanism 2 for adjustment; when rotational adjustment is required, start the rotating device 8.

[0022] The auxiliary clamp for welding copper pipes in water heaters is equipped with a movable rod 5, a spring 6, a connecting seat 7, a rotating device 8, and a clamping wheel 9. The clamping wheel 9 engages with the arc-shaped groove 301, allowing the clamp to hold and fix heat exchange tubes of different diameters, thus expanding its applicability. Simultaneously, the horizontal moving mechanism 2 allows for lateral adjustment of the welding position of the copper pipe. Combined with the rotating device 8 and the clamping wheel 9, the copper pipe can be rotated and adjusted, facilitating flexible welding operations and improving the clamp's practicality.

[0023] Specifically, it also includes a sliding guide rod 302, one end of which is connected to the connecting seat 7, and the other end of which is slidably mounted on the bracket 4.

[0024] By adopting the above structure, the sliding guide rod 302 restricts the movement direction of the movable rod 5 and the connecting seat 7, preventing the movable rod 5 and the connecting seat 7 from shifting, making the process of the movable rod 5 driving the connecting seat 7 to move along the Z-axis more stable.

[0025] Specifically, the bracket 4 includes a connecting angle plate 41 and an L-shaped plate 42. The horizontal part of the connecting angle plate 41 is connected to the support base 3. The vertical part of the L-shaped plate 42 is provided with an oblong hole 420 along the Z-axis. The vertical part of the connecting angle plate 41 is detachably connected to the vertical part of the L-shaped plate 42 by bolts and the oblong hole 420. The movable rod 5 and the sliding guide rod 302 are respectively slidably assembled on the horizontal part of the L-shaped plate 42.

[0026] Using the above structure, the connecting angle plate 41 and the L-shaped plate 42 are connected by bolts and the waist-shaped hole 420. The position of the bolts on the waist-shaped hole 420 can be adjusted according to the specific situation, and the distance between the clamping wheel 9 and the arc groove 301 can be adjusted so that the clamping wheel 9 and the arc groove 301 can better clamp and fix the copper tube.

[0027] Furthermore, the support base 3 includes a translation slider 31, a lifting base 32, and two lifting cylinders 33. The bottom of the translation slider 31 is connected to the drive end of the horizontal moving mechanism 2. Extension plates 311 extend from both ends of the translation slider 31 along the Y-axis. One lifting cylinder 33 is disposed on the extension plate 311 on one side of the translation slider 31, and the other lifting cylinder 33 is disposed on the extension plate 311 on the other side of the translation slider 31. The drive ends of the two lifting cylinders 33 are respectively connected to the bottom of the lifting base 32. The arc-shaped groove 301 is disposed on the top of the lifting base 32.

[0028] With the above structure, the lifting cylinder 33 is started synchronously, which drives the lifting seat 32 to move relative to the translation slider 31 in the Z-axis direction, thereby realizing the longitudinal adjustment of the welding position of the copper tube and further improving the practicality of the fixture.

[0029] Furthermore, the support base 3 also includes a support base guide rod 34, the bottom of the lifting base 32 is provided with a sliding groove, one end of the support base guide rod 34 is connected to the translation slider 31, and the other end of the support base guide rod 34 is inserted into the sliding groove.

[0030] By adopting the above structure, the movement direction of the translation slider 31 and the lifting seat 32 is restricted by the support guide rod 34, so as to avoid the translation slider 31 and the lifting seat 32 from deviating, making the process of the lifting cylinder 33 driving the lifting seat 32 to move along the Z-axis more stable.

[0031] Preferably, the bottom of the arc-shaped groove 301 is provided with a roller groove, and a plurality of rollers 303 are rotatably assembled in the roller groove along the X-axis direction.

[0032] By adopting the above structure, the sliding friction between the copper tube and the roller groove is transformed into rolling friction, avoiding jamming and jumping, and avoiding the problem of scratches on the outer surface of the copper tube caused by sliding friction.

[0033] Specifically, the horizontal moving mechanism 2 includes a drive motor 21, a drive screw 22, and a drive block 23. The drive motor 21 is disposed at one end of the receiving groove 11. One end of the drive screw 22 is connected to the drive end of the drive motor 21. The other end of the drive screw 22 is rotatably mounted at the other end of the receiving groove 11. The middle part of the drive block 23 is threadedly connected to the drive screw 22. The drive block 23 passes through the opening of the receiving groove 11 and is connected to the support base 3.

[0034] The horizontal moving mechanism 2 is specifically a screw drive structure, which converts the rotational motion of the output shaft of the drive motor 21 into the linear motion of the drive block 23, thereby driving the support base 3 and the copper tube it holds to move horizontally along the X-axis.

[0035] Optionally, a toggle block 71 extends outward from one side of the connecting seat 7.

[0036] The actuating block 71 provides a driving point, allowing operators to directly move the connecting seat 7 by hand or with a tool. This structure facilitates the upward movement of the connecting seat 7 by the operator.

[0037] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
