Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figures 1 and 2, the manual gear welding machine of the present invention includes a frame 1, on which a saw blade chuck 2 for installing a saw blade 7, a guide rail 6, and a sliding fit with the guide rail 6 are arranged. The sliding platform 3 is provided with a welding torch 4 and a sawtooth alloy block fixing bracket 5 on the sliding platform 3; the end of the sawtooth alloy fixing bracket 5 adjacent to the saw blade chuck 2 is located outside the sliding platform 3, and the The flame spraying direction of the torch 4 is directed toward the end adjacent to the sawtooth alloy block fixing bracket 5 and the saw blade chuck 2 .

In order to ensure the relative position of the saw blade 7 and the sawtooth alloy block when repairing. In use, both the saw blade chuck 2 and the sawtooth alloy block fixing bracket 5 can be non-adjustable, and the saw blade 7 and the sawtooth alloy block can be positioned first and then fixed on the welding machine to ensure that the saw blade 7 and the sawtooth alloy The relative positional relationship of blocks after fixing. But preferably, it is set to be adjustable, specifically, the saw blade chuck 2 can be an indexing adjustment mechanism, and the sawtooth alloy block fixed bracket 5 is fixed; it can also be that the saw blade chuck 2 is fixed, and the sawtooth alloy block fixed bracket Platform 5 is an adjustment mechanism; or both are adjustment mechanisms. Therefore, the saw blade chuck 2 and the sawtooth alloy block fixing bracket 5 can be composed of various structures.

Specifically, in order to simplify the mechanism and facilitate operation, the saw blade chuck 2 includes a connecting shaft 21 and two coaxially installed disc bodies 22, and the saw blade 7 is located between the two disc bodies 22; the connecting shaft 21 One end is fixedly connected to the frame 1, and the other end is provided with a lock nut threadedly matched with it; the disc body 22 on one side of the frame 1 is fixedly connected to the connecting shaft 21, and the disc body 22 on the other side is provided with a rotating handle 23 and is fixedly connected with the saw blade 7; the saw blade 7 and the disc body 22 fixedly connected with it are sleeved on the connecting shaft 21 and locked with the locking nut.
