However, the second method affects work efficiency because it needs to operate multiple hand levers one by one; also because the frame is fixed, it needs to be knocked off the mold after welding, which will also affect production efficiency and waste materials

Abstract

The invention discloses a welding tool clamp fixing and shaping a metal structure bottom frame. A rack with two three-legged metal frame type supporting base structures and a rectangular metal frame structural support are adopted, and the support is arranged on the rack through rotating shafts and bearings. A rotating positioning mechanism is arranged on one side of the rack, two sets of movable chucks are arranged on the two sides of the upper face of the rack. Each set of movable chuck is connected with guiding bearings, a guiding shaft and a clamping air cylinder. Each set of movable chuck is provided with a locking mechanism installing plate provided with a locking air cylinder, locking mechanisms and positioning clamps. An end cover positioning wheel, an intermediate gear positioning pin, a front gear positioning pin, a rear gear positioning pin, a fixed lock sleeve, a movable lock sleeve and an air cylinder demolding mechanism are arranged in the middle of the upper face of the rack. The welding tool clamp can perform tight clamping and loosening, demolding is flexible, operation is fast, a pneumatic tool can be manually controlled to carry out welding after the metal structure bottom frame is fixed and shaped, meanwhile, the welding precision is high, deformation is not liable to happen, and the work efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of electrical process equipment, in particular to a welding fixture for fixing and shaping the bottom frame of a metal structure. Background technique [0002] At present, products with high stability requirements for metal structures generally adopt welding and forming manufacturing methods. However, structural deformation caused by metal welding is a big problem they face. The traditional control method for deformation is to use clamping parts to fix and support the workpieces to be welded one by one in the chuck. Although this method has a certain effect on deformation control, the clamping speed is relatively slow. Work efficiency is not high. Another type of method is to weld the fixed block or the fixed frame and then press and fix it with a wrench clamp. However, the second method affects work efficiency because it needs to operate a plurality of wrench clamps one by one; a...
