Description

Technical Field

[0001] This utility model relates to the technical field of aluminum welding machines, and in particular to a clamping mechanism and an aluminum welding machine. Background Technology

[0002] An aluminum welding machine is a device specifically designed for welding aluminum and aluminum alloy materials. It melts and bonds the materials by heating or pressurizing them.

[0003] A welding platform is a platform used to support and fix the workpiece to be welded. It is typically used to ensure the stability of the workpiece and the quality of the weld during the welding process. The welding platform and the aluminum welding machine can be integrated into the design, with the aluminum welding machine as part of the welding platform, allowing direct operation on the platform. In use, the workpiece to be welded is first placed on the welding platform and secured in the appropriate position using clamps, locating pins, or other fixing devices. Then, the aluminum welding machine is started to begin the welding operation.

[0004] However, existing pipe welding clamping tools use rigid clamping tools, which compress both ends of the pipe to bring the two pipes to be welded into contact. Rigid clamping can apply excessive pressure to one end of the pipe, causing displacement during clamping, leading to localized deformation and affecting the weld quality. Furthermore, if the pipe is subjected to uneven clamping forces during welding, welding stress will be generated within the pipe, resulting in cracks or deformation after welding.

[0043] Example 1

[0044] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a clamping mechanism. This device includes...

[0045] The mounting unit 100 includes a mounting base 101, a support base 102 disposed on the mounting base 101, and an adjustment clamp 103 disposed on the mounting base 101; the mounting base 101 is mounted on the welding platform 401 and is used to fix the support base 102 and the adjustment clamp 103.

[0046] The internal support unit 200 includes a fixed column 201 mounted on the adjusting clamp 103, a fixed plate 202 mounted on the fixed column 201, and an internal support assembly 203 mounted on the fixed plate 202; and an auxiliary unit 300 includes a hydraulic base 301 mounted on the support base 102, a telescopic rod 302 slidably mounted on the hydraulic base 301, and a positioning assembly 303 mounted on the telescopic rod 302. The internal support assembly 203 on the adjusting clamp 103 provides internal support and positioning for one end of the pipe, and the positioning assembly 303 on the support base 102 is used to position and fix the weld joint of the pipe. The combined use of the positioning assembly 303 and the internal support assembly 203 fixes and limits the pipe to be welded on the adjusting clamp 103, preventing the pipe from shifting during the welding process due to excessive holding force of the adjusting clamp 103.

[0047] The inner support assembly 203 includes a groove 203a disposed on the fixed plate 202, a sliding plate 203b slidably disposed on the groove 203a, a connecting column 203c disposed on the sliding plate 203b, a limiting rod 203d disposed on the sliding plate 203b, an adjusting circular plate 203e rotatably disposed on the groove 203a, a transmission column 203f disposed on the adjusting circular plate 203e, and an adjusting bolt 203g movably disposed on the transmission column 203f; the adjusting circular plate 203e is provided with an arc-shaped groove 203h that matches the limiting rod 203d, and the adjusting bolt 203g is provided with a positioning groove 203i. The rotation of the adjusting bolt 203g drives the rotation of the transmission column 203f, which in turn drives the rotation of the adjusting disc 203e. The adjusting bolt 203g is provided with a positioning groove 203i. The transmission column 203f moves in the positioning groove 203i of the adjusting bolt 203g, which prevents the adjusting bolt 203g from moving due to rotational displacement during rotation. This keeps the adjusting disc 203e in a fixed position in the groove 203a and causes it to rotate, thus driving the limit rod 203d to move in the arc groove 203h.

[0048] The inner support assembly 203 also includes a slide rail 203j disposed on the fixed plate 202, a limiting groove 203k disposed on the slide rail 203j, a slider 203l disposed on the connecting column 203c, a connecting plate 203m disposed on the slider 203l, and an inner support bar 203n disposed on the connecting plate 203m.

[0049] The connecting column 203c is slidably disposed in the limiting groove 203k, which limits the movement of the connecting column 203c and prevents it from sliding out of the slide rail 203j. The slider 203l is slidably disposed on the slide rail 203j, and one end of the inner support bar 203n is triangularly pyramidal. The inner support bar 203n is connected to the slider 203l through the connecting plate 203m. The slider 203l moves on the slide rail 203j, which can drive the expansion and contraction of the inner support bar 203n, thereby providing internal support for the positioning of one end of pipes of different diameters. The barb at one end of the inner support bar 203n makes the contact between the inner support bar 203n and the inner wall of the pipe more compact, increasing the tension of the inner support assembly 203 in positioning one end of the welded pipe, and preventing the pipe from falling off the inner support bar 203n due to excessive holding force of the adjusting clamp 103.

[0050] During use, firstly, the operator adjusts the height and angle of the adjusting clamps 103 at both ends of the mounting base 101 according to the horizontal length of the welded pipe. Then, the two ends of the pipe are fixed to the inner support components 203 on the adjusting clamps 103. The welded pipe is then placed on the positioning component 303 of the auxiliary unit 300. Next, the operator rotates the adjusting bolt 203g at one end of the adjusting disc 203e. The rotation of the adjusting bolt 203g causes the adjusting disc 203e to rotate in the groove 203a, and the limiting rod 203d moves in the arc groove 203h. The movement of the limiting rod 203d in the arc groove 203h will cause the sliding plate 203b to move in the middle. The movement of the sliding plate 203b will cause the connecting column 203c and the slider 203l to move on the slide rail 203j. The inner support bar 203n is connected to the slider 203l through the connecting plate 203m. The slider 203l moves on the slide rail 203j, which can drive the expansion and contraction of the inner support bar 203n, thereby positioning and supporting one end of the welded pipe, preventing the rigid clamping tool from causing the pipe to shift during pipe welding, thereby improving the welding quality and the performance of the welded pipe.

[0051] Example 2

[0052] Reference Figures 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0053] The positioning component 303 includes a limiting post 303a disposed on the support base 102, a push plate 303b slidably disposed on the limiting post 303a, an anti-slip wheel 303c rotatably disposed on the push plate 303b, and a triangular plate 303d disposed on the push plate 303b; a telescopic rod 302 is disposed on the push plate 303b. The extension and retraction of the telescopic rod 302 in the hydraulic base 301 controls the sliding of the push plate 303b on the limiting post 303a.

[0054] Compared to Embodiment 1, the positioning component 303 further includes a spring 303e movably mounted on the push plate 303b at one end, a clamping plate 303f mounted on the other end of the spring 303e, an anti-slip wheel 303g mounted on one end of the clamping plate 303f, and a roller 303h mounted on the other end of the clamping plate 303f. The extension and retraction of the spring 303e provides clamping force between the clamping plate 303f and the push plate 303b. The movement of the push plate 303b drives the roller 303h to move on the triangular plate 303d, changing the angle between the clamping plate 303f and the push plate 303b. The change in angle controls the change in the clamping force between the clamping plate 303f and the push plate 303b, thereby facilitating the control of the clamping force on the surface of pipes of different diameters.

[0055] The clamping plate 303f is slidably mounted on the support base 102 via a fixed axis 303i. The fixed axis 303i is used to position the rotating clamping plate 303f.

[0056] During use, after the operator positions one end of the pipe on the inner support assembly 203, the height of the telescopic rod 302 is controlled by the hydraulic base 301. The rise or fall of the telescopic rod 302 controls the movement of the push plate 303b on the limiting post 303a. The movement of the limiting post 303a causes the triangular plate 303d to rise or fall. The roller 303h at one end of the clamping plate 303f slides on the triangular plate 303d, thereby controlling the angle between the clamping plate 303f and the push plate 303b. The spring 303e is used to provide the angle between the clamping plate 303f and the push plate 303b. By controlling the movement of the push plate 303b, the angle between the clamping plate 303f and the push plate 303b is controlled, thereby positioning and clamping the weld joints of pipes of different diameters welded by the operator, preventing the pipes from shifting during the welding process. By controlling the position and angle of the pipe, the adjustment time can be reduced and the welding process can be accelerated. Accurate positioning can ensure the consistency and uniformity of the weld joint, thereby improving the overall quality of the pipe welding.

[0057] The remaining structure is the same as that in Example 1.

[0058] Example 3

[0059] Reference Figures 1-7 This is the third embodiment of the present invention, which differs from the second embodiment in that: an aluminum welding machine includes a support unit 400, comprising a welding platform 401 disposed on a mounting base 101, and a support component 402 disposed on the welding platform 401; and an aluminum welding unit 500, comprising an aluminum welding machine body 501 disposed on the support component 402, and a control component 502 disposed on the aluminum welding machine body 501. The welding body is disposed on the support component 402, and in conjunction with the welding platform 401, the inner support component 203 on the adjusting clamp 103, and the positioning component 303 on the support base 102, the aluminum welding machine body 501 provides more stable pipe fixation during welding, thereby improving the welding quality of the aluminum welding machine body 501.

[0060] Compared to Embodiment 2, the support assembly 402 further includes a support frame 402a disposed on the welding platform 401, and a receiving box 402b disposed on the support frame 402a; the receiving box 402b is provided with an aluminum welding machine body 501. The aluminum welding machine body 501 performs welding processing on the pipes on the support base 102.

[0061] The control component 502 includes an adjustment knob 502a and an adjustment button 502b on the aluminum welding machine body 501, and an insertion hole 502c on one side of the adjustment button 502b. A mounting groove 502d is provided on the aluminum welding machine body 501, and a welding torch base 502e is movably mounted on the mounting groove 502d. The aluminum welding machine body 501 has heat dissipation holes 502f, which are strip-shaped and arranged in a linear array. The welding torch base 502e is fixedly connected to the welding torch used in the welding process to weld the pipes to be welded.

[0062] The heat dissipation hole 502f is located directly below the mounting base 502g, which has a second socket 502h for connecting other devices.

[0063] During use, the operator manipulates the adjustment knob 502a and adjustment button 502b of the aluminum welding machine body 501 to set the parameters required for pipe welding, connects the welding gun to the welding gun base 502e, and then welds the pipe to be welded on the support base 102. When it is necessary to connect other equipment, the other equipment can be connected and used through the first socket 502c and the second socket 502h.

[0064] The use of the internal support component 203 and the positioning component 303 increases the stability of the welded pipe during the welding process, increases the uniform clamping force at both ends of the pipe, reduces the welding stress generated inside the pipe, avoids cracks or deformation of the pipe after welding, and allows the welding operation to be carried out more quickly without frequent adjustments, thus increasing the practicality of the aluminum welding machine.

[0065] The remaining structure is the same as that in Example 2.
