Abstract

A dual-mode muffler valve automatic pre-twisting welding detection equipment is composed of a bracket, a torque measurement system, a drive system, a limit system, a welding system and a control system. The torque measuring system, driving system and control system are respectively fixed on the bracket, and the limit system and welding system are installed on the driving system. The torque measurement system transmits the torque to the static torque sensor through the asbestos plastic joint to realize the measurement of the torque, and at the same time isolates the impact of the heat and current generated by welding on the sensor; the drive system realizes the automatic clamping of the valve through the combination of linear motion and rotary motion and pre-twist; the limit system controls the motion boundary position of the drive system through linear motion limit and rotary motion limit; the welding system realizes the automatic welding of the torsion spring seat of the valve through the combination of cylinder and slide plate; the control system controls each The orderly movement of the system makes the three processes of pre-twisting, welding and testing of the dual-mode muffler valve automatically completed.

Description

technical field [0001] The invention belongs to the field of automatic assembly and detection devices for auto parts. Background technique [0002] With the rapid growth of car ownership, car exhaust noise pollution has become an increasingly prominent problem. At the same time, people have higher and higher requirements for car comfort, and car manufacturers urgently need to reduce exhaust noise to improve the noise level inside the car. The dual-mode muffler can effectively reduce the exhaust noise of the automobile, and at the same time reduce the volume and exhaust back pressure of the automobile exhaust muffler, and has a wide application prospect in the automobile exhaust system (Pang Jian. Automobile noise and vibration: Theory and Application, Beijing: Beijing Institute of Technology Press, 2006). [0003] The core component of the dual-mode muffler is the valve structure, which opens and closes under the action of high-temperature exhaust airflow, changes the airf...
