The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0022] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a multi-head welding machine for cement grinding discs, comprising a positioning shell 1, a grinding disc base 2, and multiple grinding blocks 8. The grinding disc base 2 is placed inside the positioning shell 1. Multiple connecting grooves are recessed on the surface of the grinding disc base 2. Each connecting groove has an installation port 11 on its inner wall. Each inner wall of the positioning shell 1 has a slot 13 opposite to the installation port 11. One end of each grinding block 8 passes through the installation port 11 and is inserted into the slot 13. The other end of each grinding block 8 extends into the connecting groove. A frame-shaped cavity 10 is formed between the grinding block 8 and the connecting groove. Each frame-shaped cavity 10 contains brazing filler metal 9 for welding and fixing the grinding block 8 to the grinding disc base 2. Multiple welding guns 6 are movably mounted on the outer ring surface of the positioning shell 1.

[0024] In this embodiment, a groove 3 is provided on the outer ring surface of the positioning shell 1. Multiple sliders 4 are slidably installed in the groove 3. The outer sides of the sliders 4 all extend through the groove 3 to the outside and are all equipped with support frames 5. The other end of the support frame 5 extends to the top of the grinding disc base 2. The welding torch 6 is installed on the other end of the support frame 5 and is vertically facing the grinding block 8.

[0025] In this embodiment, the cross-sections of both the slider 4 and the groove 3 are T-shaped, and the support frame 5 is U-shaped.

[0026] In this embodiment, the inner diameter of the cavity of the positioning shell 1 matches the diameter of the grinding disc base 2, which can position the grinding disc base.

[0027] In this embodiment, an annular groove is provided on the inner wall surface of the positioning shell 1, and a magnet 12 is installed in the annular groove. The grinding disc base 2 is magnetically fixed by the magnet 12.

[0028] In this embodiment, the length and width of the mounting port 11 are both smaller than the length and width of the connecting groove, and the length and width of the mounting port 11 are matched with the length and width of the slot 13. The length and width of the mounting port and the slot are matched with the length and width of the grinding block to ensure the stability of the grinding block after insertion.

[0029] In this embodiment, the width of the support frame 5 is greater than the diameter of the welding torch 6, and handles 7 are installed on the outer side of the support frame 5. The handles facilitate pushing the support frame, and because the support frame is wider, it can block the flames sprayed from the welding torch, thus avoiding burns to the operator's hands.

[0030] In this embodiment, the welding torches 6 are all jet welding torches, which allow the ejected flames to cover the brazing filler metal and prevent it from melting rapidly.

[0031] Working principle: First, insert the grinding block into the slot, then put the grinding disc base into the positioning shell, and make the mounting port on the grinding disc base fit onto the grinding block to achieve the effect of circumferential positioning. The grinding disc base can be magnetically fixed by magnets to ensure its stability.

[0032] After the grinding block and grinding disc substrate are positioned, the brazing filler metal of the frame structure can be placed into the frame groove, and the welding torch can rotate along the slide. When rotating, hold the handle and pull the support frame. The movement of the support frame drives the slider, which moves along the slide. The movement of the support frame also drives the welding torch simultaneously until the welding torch is positioned opposite the grinding block below. The vertically downward sprayed flame can directly melt the brazing filler metal to achieve the purpose of rapid welding. Moreover, there are multiple welding torches, which can complete the welding of multiple grinding blocks at one time, increasing efficiency.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
