[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be pointed out that the technical solution and design principles of the present invention will be described in detail below only with an optimized technical solution, but the protection scope of the present invention does not limited to this.

[0022] The described embodiment is a preferred implementation of the present invention, but the present invention is not limited to the above-mentioned implementation, without departing from the essence of the present invention, any obvious improvement, replacement or modification that those skilled in the art can make Modifications all belong to the protection scope of the present invention.

[0023] like figure 1 , figure 2 As shown, the vehicle tailgate sealing ring matching surface detection device for actual working conditions simulation of the present invention is composed of a frame module, a working condition simulation module, a positioning module, a measurement module, a control module and a host computer, wherein the frame module is used for installing Each module of the fixed detection device includes the bottom plate and the supporting frame; the working condition simulation module is used to simulate the actual working condition, including the sealing ring supporting sheet metal; the positioning module is used to install and fix the tailgate of the car to be tested, including 3 positioning pads, 2 counterpart bolt positioning blocks, 1 counterpart positioning lock and 2 fixed torque wrenches; the measurement module is used to measure the matching surface data of the tailgate seal ring, including sensor reference table, displacement sensor and zero calibration block; control module It is used to control the measurement process, including PLC controller and solenoid valve; the host computer is used to store, analyze and display the measurement results.

[0024] The bottom plate is used to carry various functional components;

[0025] The support frame is used to install the working condition simulation module, the positioning module and the measurement module, and is located on the bottom plate;

[0026] The sealing ring supports the sheet metal, installed on the supporting frame, and is used to carry the pasted sealing strip during the measurement, and is designed according to the profiling of the vehicle to be tested; the sealing ring supporting sheet metal is composed of multiple sections, and each section of the supporting sheet metal is used To install the displacement sensor; in this specific embodiment, the sealing ring support sheet metal is made up of 12 sections;

[0027] The positioning pad is located on the support frame and is used for installing the positioning block of the counterpart bolt and the positioning lock of the counterpart;

[0028] The counterpart bolt positioning block is designed according to the counterpart of the tailgate of the vehicle to be tested, and is used to tighten the tailgate of the vehicle and connect it to the detection device to simulate the actual loading state and install it on the positioning pad;

[0029] The positioning lock of the counterpart is designed according to the counterpart of the tailgate of the vehicle to be tested. It is used to connect the product lock of the tailgate of the vehicle to the detection device, simulate the actual loading state, and install it on the positioning pad;

[0030] Fixed torque wrench, which is used to quantitatively control the locking force when the tailgate of the car to be tested is positioned and locked with the counterpart bolt;

[0031] The sensor reference platform is used to install the displacement sensor, and is located between each supporting sheet metal, and is fixed on the supporting frame; in this specific embodiment, there are 12 sensor reference platforms, located between the 12 sections of sealing ring supporting sheet metal;

[0032] The displacement sensor is installed on the sensor reference platform, and is used to detect the matching surface size of the sealing ring; in this specific embodiment, there are 12 displacement sensors, which are respectively installed on the 12 sensor reference platforms;

[0033] Zero calibration block, used for sensor zero calibration;

[0034] The PLC controller is used to control the detection process and is connected with the solenoid valve and the host computer;

[0035] Solenoid valve, used to control the air supply of the displacement sensor.

[0036] figure 2 Shown is the flow chart of the detection method for the matching surface of the automobile tailgate seal ring simulated in actual working conditions, including the following steps:

[0037] (1) Paste the sealing strip, paste the sealing strip on the supporting sheet metal of the sealing ring and zero it;

[0038] (2) Install the tailgate of the car, use a fixed torque wrench to connect the tailgate of the car with the bolt positioning block of the opponent's bolt, and fix the product with the positioning lock of the opponent's part. If the product is too deformed and the installation cannot be completed, replace the product ;

[0039] (3) The displacement sensor collects data, the upper computer system starts the detection process, and the displacement sensor automatically collects data from the sealing ring matching surface;

[0040] (4) The PLC controller reads the data collected by the displacement sensor and transmits it to the upper computer system;

[0041] (5) The upper computer system reads, analyzes and displays the test results;

[0042] (6) The sensor returns automatically;

[0043] (7) Release the fixed connection between the counterpart bolt positioning block, the counterpart positioning latch and the tailgate of the vehicle, and remove the tailgate of the vehicle.
