[0002] As an economical and rapid process for modifying material surfaces, hardfacing is increasingly being used in the manufacture and repair of parts across various industrial sectors. To maximize the effectiveness of the hardfacing layer, it is desirable to employ a hardfacing method that exhibits minimal base material dilution, a high deposition rate, and excellent hardfacing layer performance—in other words, a high-quality, efficient, and low-dilution hardfacing technology.
[0003] In the production of sector rollers in the prior art, it is necessary to change the surface material properties of the rollers by surfacing welding according to the use requirements, so as to improve the wear resistance and corrosion resistance of the workpiece. During surfacing welding, the rollers are usually clamped and fixed by a clamp. If the clamp is not clamped tightly enough or the clamp is damaged and loose, it is easy to cause the roller to fall, posing a certain safety hazard. Therefore, a sector roller surfacing welding tool is needed. Utility Model Content

[0012] By adopting the above technical solution, one end of the roller can be supported by the fixing plate without affecting the normal rotation of the roller, thereby reducing the load on the output shaft of the motor.
[0013] Optionally, support columns are fixedly connected to the four corners of the bottom end of the workbench.
[0014] The adoption of the above technical solution is conducive to providing stable support for the workbench.
[0015] Optionally, there are two extension screws, and the two extension screws are symmetrically arranged on the left and right.
[0016] By adopting the above technical solution, the baffle can be locked, further improving the firmness of the baffle installation.
[0017] Optionally, the baffle and the limiting plate are an integrated structure.
[0018] The adoption of the above technical solution is conducive to improving the firmness of the connection between the baffle and the limit plate.
[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0020] The technical solution of the present application can install the baffle through the mounting frame, and then fix the baffle through the extended screw. The baffle blocks both sides of the roller, which can prevent the roller from accidentally falling and hitting the surrounding staff. Under the action of the limit plate, the roller can be prevented from falling and bouncing again, further improving the protection effect for the surrounding staff. Through the mutual cooperation of the above structures, safety hazards can be avoided during the surfacing welding of the roller. BRIEF DESCRIPTION OF THE DRAWINGS
