The two sets of support and positioning assemblies are slidably arranged with the two sets of slide rails. Two sets of clamping assemblies are symmetrically arranged at the top of the base, each clamping assembly having a spot welding assembly. In use, multiple heat sinks are positioned and supported by the two sets of support and positioning assemblies. Then, the two sets of clamping assemblies magnetically attract a straight tube. The two sets of clamping assemblies then move mirror-imagely, causing the arc-shaped grooves on both sides of the heat sinks to contact the straight tubes. Simultaneously, the clamping assemblies fix the left and right ends of the multiple heat sinks. Finally, the spot welding assembly is used to spot weld the contact parts between the heat sinks and the straight tubes, improving processing efficiency.

[0006] Preferably, the support positioning component includes a first slider, a first movable seat, a first positioning plate, and a first positioning slot. Two sets of first sliders are provided at the bottom of the first movable seat, each set of first sliders being slidably connected to a set of slide rails. A first positioning plate is provided at the top of the first movable seat, and multiple sets of first positioning slots are provided at the top of the first positioning plate. Based on the length of the heat sink, the first slider slides on the slide rails, thereby adjusting the distance between the two sets of first movable seats, and further adjusting the distance between the two sets of first positioning plates. After adjustment, the heat sink is placed into the first positioning slots where the two sets of first positioning plates overlap for positioning, improving flexibility.

[0007] Preferably, the clamping assembly includes a bearing housing, a motor, a lead screw, a second slider, a second movable seat, a second positioning plate, a second positioning slot, a magnet, and a mechanical cross arm. A set of bearing housings and a set of motors are respectively installed at the top of the base. A lead screw is installed at the motor output end, with one end of the lead screw rotatably connected to the bearing housing. Two sets of second sliders are installed at the bottom of the second movable seat, each set of second sliders being slidably connected to a set of slide rails. The second movable seat is threadedly connected to the lead screw. Two sets of second positioning plates and a set of mechanical cross arms are installed at the inner end of the second movable seat. Each set of second positioning plates has multiple sets of second positioning slots. Two sets of magnets are installed on the mechanical cross arm, and the magnets magnetically attract the straight tube. In use, multiple heat sinks are positioned through the first positioning slot, and the magnets magnetically attract the straight tube. The controller starts the two sets of motors, causing the two sets of second movable seats to mirror each other and move closer together, further allowing the straight tube to enter the arc-shaped opening of the heat sink. At the same time, the second positioning slots on the second positioning plate clamp and fix the left and right sides of the heat sink, improving convenience.

In use, the controller causes the movable bases to move intermittently at equal intervals on the electric slide rails, and the electric cylinders drive the spot welding mechanisms closer to the heat sink, thereby enabling the spot welding mechanisms to spot weld the contact area between the heat sink and the straight pipe, improving processing efficiency.

[0009] Preferably, the device also includes adjustable feet, with a set of adjustable feet provided at each of the four corners of the bottom of the base; the four sets of adjustable feet work together to provide stable support for the device and improve stability.

Then, two sets of clamping components magnetically attract a set of straight tubes. After that, the two sets of clamping components move in a mirror image, so that the arc-shaped slots on both sides of the heat sinks contact the straight tubes. At the same time, the clamping components fix the left and right ends of the multiple sets of heat sinks. Then, the spot welding components are used to spot weld the contact parts between the heat sinks and the straight tubes, thereby improving processing efficiency. Attached Figure Description
