There is also a fine-tuning step between step S3 and step S4, in which after the rolling element 19 and the rod material to be fixed are against each other, the fixed rod material is moved again by the clamping assembly 2 for fine-tuning.
[0052] The rod material fixing device, rod material welding equipment, rod material fixing and welding method of the present invention gradually increases the diameter of the end of the positioning rod 172 close to the first baffle 131 from the end to the middle position, so that the end side wall of the positioning rod 172 has a guiding function, and the positioning rod 172 cooperates with the positioning hole of the plate material 6 to be fixed, so that the positioning rod 172 can position the plate material 6 to be fixed, and the center line of the mounting hole 61 of the plate material 6 to be fixed is in line with the center line of the rod material to be fixed, thereby improving the welding accuracy of the plate material and the rod material. The rolling element 19 cooperates with the clamping assembly 2 to allow the rod material to be fine-tuned.
[0053] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
