Movable connector rapid positioning and clamping tool used for pipelines

Abstract

The invention relates to the field of positioning and clamping tools, in particular to a movable connector rapid positioning and clamping tool used for pipelines. The movable connector rapid positioning and clamping tool comprises an opening chuck used for clamping a movable connector. The movable connector rapid positioning and clamping tool is characterized by further comprising a clamping body used for positioning the movable connector; the clamping body comprises a movable piston assembly and a movable positioning and clamping head connected with the piston assembly; the positioning and clamping head can extend into a positioning hole of the movable connector so that the rotation central line of the movable connector and the rotation central line of the positioning and clamping head can coincide. The movable connector rapid positioning and clamping tool has the advantages that the labor intensity is lowered during the clamping work of movable connector assembling, the assembling efficiency is improved, the clamping quality of the movable connector is improved, the clamping deformation of the movable connector can be eliminated so that the assembling quality can be improved, the positioning accuracy of the movable connector is improved, and the automatic connection of the movable connector and the pipelines can be achieved through the mechanical device.

Description

technical field [0001] The invention relates to the field of positioning and clamping tooling, in particular to a quick positioning and clamping tooling for a flexible joint for pipelines. Background technique [0002] A large number of metal pipe threads are used to connect pipelines in brakes and living devices on railway vehicles. The characteristics of the car body structure make the pipeline layout complicated and require a large number of unions to connect the pipeline system. Due to the unique shape and structure of the joint and the need to carry a large moment load during assembly, the clamping method of the threaded connection between the joint and the pipeline has always been clamped by manual vise, which has the following problems: 1. The labor intensity of the clamping operation Large, low efficiency; 2. The clamping force is not easy to control. If the clamping force is too large, the joint will deform and affect the assembly quality. If the clamping force is...

Problems solved by technology

Due to the unique shape and structure of the joint and the need to carry a large moment load during assembly, the clamping method of the threaded connection between the joint and the pipeline has always been clamped by manual vise, which has the following problems: 1. The labor intensity of the clamping operation Large, low efficiency; 2. The clamping force is not easy to control. If the clamping force is too large, the joint will deform and affect the assembly quality. If the clamping force is too small, the joint cannot be effectively fixed and the assembly operation cannot be completed; 3. The positioning and fastening of the joint The stability of the joint is poor, and the connection between the union and the pipeline can only be done manually, and it is impossible to implement mechanization and automation.
