The invention provides a hinged pull rod assembly inspection tool which comprises a base, a telescopic piece, a pressure detection piece and a supporting seat, the telescopic piece and the supportingseat are both arranged on the base, the supporting seat is used for fixing a hinged pull rod, and the telescopic direction of the telescopic piece and the axis of the hinged pull rod are coaxially arranged. The pressure detection piece is connected with the movable end of the telescopic piece and located between the telescopic piece and the hinge pull rod. According to the hinge pull rod assembling and inspecting tool, pressing force is applied to the hinge pull rod through the telescopic piece, and outer sleeve assembling and welding, inner sleeve assembling and welding and spring installingof the pull rod are achieved; the pressure detection piece is arranged at the movable end of the telescopic piece, the pressing force applied by the telescopic piece can be directly measured, and themechanical property of the pull rod can be conveniently tested; and the problems that in an existing hinged pull rod assembling mode, time and labor are wasted in assembling operation, and clamping needs to be conducted again during testing are solved.
Description
technical field [0001] The invention relates to the technical field of assembly tooling for elastic parts, in particular to a tooling for assembly and inspection of hinged tie rods. Background technique [0002] The low-floor vehicle articulated device is a connecting device for low-floor vehicles. It is a vehicle component that enables the vehicles to be connected, transmits traction, braking force and impact force, and keeps a certain distance between the vehicles. [0003] The assembly process of the tie-rod hinge has its own assembly method in each company. At present, most of the assembly operations of the hinged tie rod are assembled through the jack rod with a hydraulic cylinder, and then the mechanical properties of the hinged tie rod are tested with special equipment. There is the problem of time-consuming and labor-intensive assembly work, and the problem that re-clamping is required during testing. [0004] To sum up, there is an urgent need for a hinged tie rod ...
