Welding equipment for producing numerical control lathe shell

The utility model discloses welding equipment for producing a numerical control lathe shell, which comprises a device main body, a welding module is arranged in the device main body, a fixing plate is fixedly connected to the inner wall of the device main body, a hole is formed in the fixing plate, a sliding groove is formed in the device main body, and a filter screen is slidably connected to the interior of the sliding groove. According to the welding equipment for producing the numerical control lathe shell, through the arrangement of the draught fan, operators do not need to sweep chippings on the surface of the fixing plate manually, through cooperation of holes and a filter screen, the chippings can stably stay on the surface of the filter screen under the action of wind power, and therefore the chippings are prevented from falling off. Through mutual cooperation of an inserting rod, a pulling plate and a first spring, the filter screen can be fixed, the filter screen is stabilized in the device body, t
