[0025] The following is combined with Figure 1-Figure 5 The utility model is described in further detail:

[0026] like Figure 1 As shown, this embodiment discloses a multi-layer welding head, including a base 1, a first clamping unit 2, a second clamping unit 3, a floating clamp assembly 4 and a heating assembly 5. The bottom of the base 1 is movably connected to the welding machine body through a guide rail pair. The first clamping unit 2 and the second clamping unit 3 are symmetrically arranged on the two adjacent sides of the base 1 and are movably connected to the base 1 through the guide rail pair. There are four groups of floating clamp assemblies 4, which are movably connected to the first clamping unit 2 and the second clamping unit 3 through the guide rail pair, and the clamping ends of the floating clamp assembly 4 are relatively arranged. The heating assembly 5 is movably connected to the base 1; the guide rail pair includes a guide rail and a slider matching the guide rail, and the slider is movably connected to the guide rail.

[0027] like Figure 2 As shown, the floating pressure clamp assembly 4 includes a first pressure clamp 41, a second pressure clamp 42, a fixed clamp 43 and a cylinder. The first clamping unit 2 and the second clamping unit 3 are both provided with multiple sections of evenly spaced linear guide rails. The fixed clamp 43 is fixedly connected to the first clamping unit 2 and the second clamping unit 3 by fastening bolts. The first pressure clamp 41 and the second pressure clamp 42 are movably connected to the linear guide rails in sequence, and the two are movably connected to the fixed clamp 43 through the cylinder; the second pressure clamp 42 and the fixed clamp 43 are provided with a clearance groove 44.

[0028] like Figure 3 As shown, a V-shaped guide rail is provided on the upper surface of the base 1, and the first pressing unit 2 and the second pressing unit 3 are movably connected to the V-shaped guide rail through a pressing cylinder 7, and the cylinder body of the pressing cylinder 7 is fixedly installed above the base 1 through a connecting plate.

[0029] like Figure 4 As shown, the heating assembly 5 includes a bracket 51, a heating cylinder 52 and a heating plate 53. The bracket 51 is fixedly installed above the base 1 by fastening bolts, the cylinder end of the heating cylinder 52 is fixedly connected to the bracket 51 by fastening bolts, and the heating plate 53 is movably connected to the base 1 through the heating cylinder 52.

[0030] like Figure 5 As shown, the pushing assembly 6 includes a pushing plate and a pushing cylinder. The cylinder end of the pushing cylinder is fixedly connected to the first clamping unit 2 by a fastening bolt. A linear guide rail is provided on the side end face of the base 1, and the pushing plate is movably connected to the linear guide rail through the pushing cylinder.

[0031] The working principle of a multi-layer welding head of the utility model is:

[0032] According to the welding requirements of the processed profile, the position of the floating pressure clamp assembly 4 and the heating plate 53 is confirmed in advance. The heating plate 53 is driven by the heating cylinder 52 and is close to the floating pressure clamp assembly 4 to facilitate the subsequent heating of the profile; the profile is placed in the makeshift groove 44 of the fixed clamp 43 and the second pressure clamp 42 in sequence, and the cylinder is started. The piston part is based on the cylinder body feed movement, and the first pressure clamp 41 and the second pressure clamp 42 are pulled by the piston part to move synchronously and close step by step, thereby compacting the double-layer profile. Four sets of floating clamp assemblies 4 can melt and weld eight products at the same time; the first clamping unit 2 and the second clamping unit 3 are driven by the clamping cylinder 7 to move above the base 1 to clamp the profile; after the profile is welded, the clamping cylinder 7 and the heating cylinder 52 retreat in turn to release the restriction on the heating plate 53, and then the clamping cylinder 7 is fed and closed again to make the profile butt-fused; finally, the cylinder is lifted, the clamping cylinder 7 retreats, and the pusher plate is driven by the pusher cylinder to move above the base 1 to take out the profile and complete the fusion welding.

[0033] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
