Problems solved by technology

The traditional intake manifold is a metal casting. At present, most intake manifolds are made of aluminum alloy. Due to the complex structure of the intake manifold, metal mold sand casting is generally used. The surface is rough, the inflation resistance is large, and the quality is large. In order to meet the requirements of reducing weight, reducing fuel consumption, improving engine performance and reducing emissions, some automobile manufacturers have begun to use nylon plastic intake manifolds. Plastic intake manifolds have the advantages of light weight, low production costs, small airflow resistance, and low noise. Advantages, however, because the strength of plastic is not as strong as metal, in order to ensure that the plastic intake manifold can work reliably, it is necessary to embed a metal sleeve on the connecting end of the plasti...

Abstract

The invention discloses a detection device for metal embedded pieces of a plastic intake manifold. The detection device for the metal embedded pieces of the plastic intake manifold comprises a frame, a detection probe signal processor and an alarm apparatus, an operating platform is arranged in the middle of the frame, an intake manifold fixing table plate is arranged on the operating platform, positioning protruding blocks matched with exhaust ports of the intake manifold are arranged on the intake manifold fixing table plate, fixed detection probes for detecting an intake manifold engine connecting flange face metal sleeve are further arranged on the intake manifold fixing table plate, and a movable detection mechanism for detecting throttle valve connecting flange face nuts is further arranged at the portion, on the lateral side of the intake manifold fixing table plate, of the frame. By means of the detection device, whether embedding missing of the metal embedded pieces in the plastic intake manifold occurs or not and whether embedding of the metal embedded pieces meets the design requirement or not can be rapidly detected, and the detection device has the advantages that the detection speed is high, the detection result is high in accuracy, and the labor intensity of workers is low.

Example Embodiment

[0011] The detection device of the plastic intake manifold metal implanted part of the present invention will be further described in detail below with reference to the accompanying drawings.
[0012] Such as figure 1 As shown, the plastic intake manifold metal implant detection device of the present invention includes a frame 2, a detection probe signal processor 8 and an alarm 7. An operating platform is provided in the middle of the frame, and an air intake is provided on the operating platform Manifold fixing platen 11, the intake manifold fixing platen is provided with positioning protrusions 10 that match the exhaust ports of the intake manifold, and a detection intake manifold is also provided on the intake manifold fixing platen The fixed detection probe 9 of the metal sleeve on the flange surface of the engine connecting flange is also provided on the frame on the side of the fixed platen of the intake manifold to detect the movement detection mechanism 6 of the nut on the flange surface of the throttle valve connection. There is a bracket nut movement detection mechanism (12, 13) for detecting the intake manifold bracket nut, and an engine cover nut movement detection mechanism 3 and a temperature sensor nut movement detection mechanism are also provided on the frame above the intake manifold fixed platen 4. Pressure sensor nut movement detection mechanism 5. The movement detection mechanism includes a fixed base 15 on which a driving cylinder 17 is fixed, and a movable flange plate 14 is provided at the end of the piston of the driving cylinder. A detection probe 9 is provided, and a guide rod 16 is provided on the back of the moving flange plate. A guide hole matching the guide rod is provided on the base. The driving cylinder is connected to the control solenoid valve through the guide tube 1, and the detection probe transmits the signal through a wire. To the signal processor of the detection probe. The detection probe is a detection probe with metal detection and positioning functions.
[0013] figure 2 Shows the use state of the plastic intake manifold metal implant detection device of the present invention. The plastic intake manifold 18 exhaust port surface and the intake manifold fixed platen are attached and fixed by positioning bumps to make The fixed detection probe is attached to the implanted area of ​​the casing on the flange surface of the intake manifold engine connection, and the control solenoid valves are activated to make the detection probes of all the mobile detection mechanisms close to the implanted area of ​​the corresponding metal implant 19. , Each detection probe transmits the detection signal to the detection probe signal processor, and the processor judges whether the metal implant is leaked or not, and the alarm outputs the corresponding prompt signal. After the detection is completed, the cylinder of each detection mechanism is moved Reset, move the plastic intake manifold out of the detection device to complete a detection.
