A device and method for cleaning throttle valves in batches

Abstract

The invention relates to a device and method for massively cleaning throttle valves and belongs to the technical fields relevant to mechanical engineering and vehicle engineering. A device part mainly comprises a base. Multiple throttle valve location and immersion mechanisms are arranged on the base. Each throttle valve location and immersion mechanism comprises a support and a lifting oil cylinder, wherein each support and the corresponding lifting oil cylinder are fixedly connected with the base. A throttle valve mounting seat is mounted on each support in a sliding manner. An opened cup is fixedly connected to each lifting oil cylinder, and each opened cup is located below the corresponding throttle valve mounting seat. One or more supports are provided with servo motor controllers. Each servo motor controller is provided with multiple signal output lines. According to the device and method for massively cleaning the throttle valves, a novel structure is designed, and the lower portions of annular side faces of throttle valve plates can be immersed in a standard throttle valve cleaning agent so that sealing of the throttle valves cannot not be damaged basically while part of carbon deposition of the throttle valve plates can be removed; in addition, harm to bodies of technical personnel can be lowered; and the device and method are quite applicable to vehicle repair enterprises and vehicle design and component suppliers.

Description

technical field [0001] The invention relates to the related technical fields of mechanical engineering and vehicle engineering, in particular to a device and method for cleaning throttle valves in batches. Background technique [0002] Throttle valve (throttle valve) is a controllable valve used to control the air entering the engine. After entering the intake pipe, it is mixed with gasoline to become a combustible mixture and participate in combustion to do work. [0003] In terms of control mode and structure, throttle valves generally include mechanical throttle valves and electronic throttle valves. [0004] The mechanical throttle generally applies a torque to the valve plate through a zipper (or called a pull wire) to overcome the torque of the torsion spring of the throttle assembly itself, so that the valve plate rotates relatively to realize the opening of the throttle (that is, intake air). [0005] The main difference between the electronic throttle valve and the...

Problems solved by technology

[0021] Although this device can keep the valve plate in the open state for a long time, it still belongs to "removing and cleaning the throttle valve with carburetor cleaning agent" in essence, because the throttle valve assembly cannot be rotated as a whole after it is fixed, so there are still influences. Disadvantages of service life of valve and health of technicians

[0022] At the same time, the existing electronic throttle valves all use a servo motor and a torque conversion mechanism to drive the valve plate to rotate, and the servo motor is usually located inside the throttle valve assembly, and the non-output end of the output shaft of the servo motor exposed outside the motor housing is only It is about 2mm, so it is difficult to use the rotating disk and the matching structure in the above scheme to drive the output shaft of the servo motor to rotate
