Description

TECHNICAL FIELD

[0001] The utility model relates to a welding device, especially a workbench with a welding box cover. BACKGROUND

[0002] Sand casting refers to the method for producing castings in sand molds, and a sand mold cover is indispensable in production because different workpieces require different sand molds, so the sizes of the sand mold covers are different, and the sand mold covers are cracked or deformed in use, so they become consumables in sand casting, so enterprises usually weld iron plates according to needs. Welding a sand mold cover requires surrounding and fixing the iron plates, and then welding the connecting parts, so an auxiliary tool for fixing the iron plates is needed during the welding process. After surrounding the iron plates, the workers need to weld multiple connecting parts around the workbench, which is very inconvenient and time-consuming and laborious.

[0003] Chinese patent CN206010272U discloses a rotary table with a brake device, which can rotate the workbench during welding. When rotation is needed, the rotary table is rotated by stepping on the foot pedal and using the handle. When the rotary table is rotated to the appropriate position, the foot pedal is released to fix the rotary table. However, the rotary table needs to be rotated by the handle, so the worker needs to put down the protective tool or welding gun to operate the rotary table, which is not convenient for welding. Moreover, the rotary table does not have a tool to fix the iron plates. UTILITY MODEL CONTENTS
