Electroslag Pressure Welding Fixture Concentrically Contracted

Abstract

The invention particularly provides an electro-slag pressure welding clamp achieving coaxial retraction. The electro-slag pressure welding clamp achieving coaxial shrinkage is characterized by comprising a control box, a jaw sliding opening, an upper jaw, a lower jaw and a gear bearing are arranged in the control box, wherein an upper sliding rack is arranged on the back side face of the upper jaw, a lower sliding rack is arranged on the back side face of the lower jaw, the upper side and lower side of the upper sliding rack and the upper side and lower side of the lower sliding rack are provided with horizontal sliding ways correspondingly, the upper sides and the lower sides of the horizontal sliding ways are provided with horizontal sliding shafts, the horizontal sliding shafts are installed in the horizontal sliding ways, tooth buckles are arranged on the gear bearing and are mechanically connected with the upper sliding rack and the lower sliding rack, so that a gear transmissiondevice is formed, and a torque spanner is arranged on the gear bearing. According to the electro-slag pressure welding clamp achieving coaxial retraction, the upper jaw and the lower jaw conduct axisretraction at the same time under the action of external force, so that the purpose of axis clamping of reinforcing steel bars is achieved, the eccentricity degree can be controlled during reinforcingsteel bar welding, and therefore the purposes of guaranteeing the project quality, saving labor and reducing the construction cost are achieved.

Description

technical field [0001] The invention relates to the field of welding construction, in particular to an electroslag pressure welding jig with concentric contraction. Background technique [0002] Electroslag pressure welding is to place two steel bars in a vertical butt joint form, use the welding current to pass through the gap between the two steel bars, form an arc process and an electroslag process under the flux layer, generate arc heat and resistance heat, melt the steel bars, and pressurize. A pressure welding method. However, during this process, the welding machine fixture cannot effectively control the axis butt joint during welding of heterosexual steel bars, which makes it difficult for operators to operate and control the quality of the project during the construction process. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects and provide a fixture for electroslag pressure welding so as to control ...
