Abstract

Automatic pre-twisting, welding and detecting equipment for a dual-mode silencer valve is composed of a support, a twisting force measuring system, a driving system, a limiting system, a welding system and a control system, wherein the twisting force measuring system, the driving system and the control system are fixed to the support, and the limiting system and the welding system are installed on the driving system. The twisting force measuring system transmits the moment of force to a static torque sensor for measuring the moment of force through an asbestos plastic connector, and impact of heat and currents generated by welding to the sensor is isolated; the driving system realizes automatic clamping and pre-twisting of the valve through the combination of linear motion and rotational motion; the limiting system controls the motion boundary position of the driving system through linear motion limitation and rotational motion limitation; the welding system automatically welds a valve torsion spring fixing base through the combination of an air cylinder and a sliding plate; the control system controls orderly motion of the other systems through programs, and pre-twisting, welding and detecting of the dual-mode silencer valve can be 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...
