Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] Such as Figure 1~3 As shown, the phase shifter lock pin gap detection equipment includes a rotor positioning seat 2, the rotor positioning seat 2 is fixedly connected with the working platform 1, and a rotating table 3 is arranged on the rotor positioning seat 2 to be able to rotate freely. Place the product to be tested on the rotor positioning seat 2. The inside of the product is the rotor shaft hole. The upper end of the rotor positioning seat 2 extends into the rotor shaft hole. The rotating table 3 uses positioning pins to position the product rotor, and then locks the rotor in the On the bolt positioning hole 21 of the rotor positioning seat 2.

[0022] A connection block 4 is connected to the turntable 3, and a group of cylinder jacking mechanisms are arranged symmetrically on the left and right sides of the connection block 4, and the jacking cylinder 5 dri...

Abstract

The invention discloses phase shifter locking pin gap detection equipment and detection method. A product rotor is positioned on a rotor positioning seat, a product locking pin hole is rotated to the side by using a turning table and a jacking mechanism, a detection cylinder is started, a detection head replaces a previous jacking cylinder to continuously keep the locking pin hole on the side, the jacking cylinder on the other side jacks in the opposite direction, the detection head is passively moved a stroke, the stroke is acquired by a data processor and converted into a locking pin gap value to be detected. The equipment and the method can quickly and effectively detect whether the product locking pin gap is qualified, and make a qualified label.

Description

technical field [0001] The invention relates to a detection device and a detection method for a lock pin gap of a phase shifter in a variable valve timing control system (VVT) of an engine. Background technique [0002] With the development of technology, variable valve timing system (VVT) technology is more and more widely used in the field of passenger cars. Due to the requirements of environmental protection regulations and energy consumption regulations, VVT technology has become the standard configuration of passenger cars. However, due to the structural characteristics of the traditional hydraulically actuated VVT, if there is a large gap between the lock pins when the engine is cold, there may be a short-term abnormality due to the lack of sufficient oil in the phase-driven actuator. ring. When the oil fills the working cavity, the abnormal sound will be eliminated automatically. Although the abnormal sound time is very short, it will have a certain impact on the co...
