Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a clamping and fixing device which is convenient for processing a door-type frame. Background Art
[0002] The door-type frame is a rectangular frame with an open end. It is widely used in various occasions, such as the frames at both ends of some iron beds or the backrests of chairs, which are all formed by welding the door-type frame with other pipe fittings. However, since the door-type frame is open at one end, in order to improve the strength of the door-type frame and ensure that it will not deform during use, it is usually necessary to set a support rod at the inner end of the door-type frame.
[0003] Since the cross-section of some portal frames is cylindrical, when welding the support rod at the inner end of the portal frame, the portal frame is mostly placed flat on the ground or a plane, and then after simple fixation, the operator places the support rod in the portal frame for welding. However, according to this method, when welding, since the bottom is not convenient for welding, the welding may not be very strong, and there may be more than one support rod welded inside the portal frame. When welding other support rods, it is not convenient to translate the portal frame, and the staff needs to move around to perform welding. Due to the line length of the welding machine, the welding may be affected. Utility Model Content
