Abstract

The invention particularly relates to an assembling and welding clamp for an integrated connecting handle. The assembling and welding clamp comprises a supporting component, a positioning component and a locking component, wherein the upper end of the supporting component is in threaded connection with the positioning component, and the locking component penetrates through the central position ofthe positioning component and is connected with the positioning component. According to the assembling and welding clamp for the integrated connecting handle, the assembling and welding difficulty ofthe integrated connecting handle is lowered, welding deformation can be effectively controlled, and it is guaranteed that assembling and positioning of the product meet the using requirement.

Description

technical field [0001] The invention relates to the technical field of fuel assembly assembly, in particular to an integrated connecting handle assembly welding fixture. Background technique [0002] The control rod assembly mainly controls the reaction of the core by gradually inserting or withdrawing the control rod into the fuel assembly. The CF connecting handle is one of the key parts of the Hualong No. 1 nuclear fuel control rod assembly. It is mainly used for suspending and positioning the control rod bundle, ensuring that the control rod can be quickly inserted into the fuel assembly during emergency shutdown, and absorbing the remaining impact energy at the end of the rod drop stroke. , to prevent impact damage to fuel assemblies. The one-piece connecting handle is a new product, in the shape of a star, which consists of one integrated handle body and 24 connecting rods. Because the control rod bundle that is suspended and positioned below it is to be quickly dropp...
