specific Embodiment approach 1

[0019]Specific implementation mode one, combinationfigure 1 Explaining this embodiment, an EMU wiper installation inspection device is composed of a power supply module, a control module, a data communication module, a wireless controller, an electrical connection port, a wiper liquid water tank, a liquid pump motor, and a liquid valve. Switches, liquid output ports, etc.; the electrical part is connected to the control module and data communication module by the power module to provide power for it. The wireless control module sends various operating condition control commands to the control module through the data communication module. The connection port outputs power of different standards to the wiper motor and collects the feedback signal of the wiper motor to form precise control. The wiper motor mechanism is controlled to drive the wiper arm to complete the stroke and swing speed under different working conditions. The control module outputs voltage to the liquid pump motor ...

specific Embodiment approach 2

[0020]Specific implementation mode two, combinationfigure 2In this embodiment, the method for installing the wiper system based on the wiper installation inspection device of the EMU is described. The method is implemented by the following steps:

[0021]1. Fix the wiper motor mechanism (integrated frame with wiper motor and wiper arm transmission mechanism) and the wiper liquid nozzle on the steel structure of the EMU car body, and then place the EMU wiper installation inspection device inside the EMU vehicle. The electrical connection port is connected to the wiper motor, the liquid output port is connected to the wiper liquid nozzle input end, the system power is turned on, the liquid valve switch is turned on, and the operation area is outside the vehicle.

[0022]2. Press the "center" function key on the wireless controller, and the data communication module decodes the transmission control module to control the wiper motor mechanism to run to a specified angle and stay there through...

Abstract

The invention discloses a windshield wiper system installation method based on a motor train unit windshield wiper mounting inspection device, relates to the technical field of motor train unit manufacturing, and solves problems that according to an existing mounting method, wiper arm middle position deviation and wiper arm shaking are likely to occur, and dynamic matching of data cannot be achieved. According to the installation method for optimizing the windshield wiper system based on the motor train unit windshield wiper installation inspection device application, accurate adjustment of installation data of all working condition positions can be achieved in the assembly stage; meanwhile, all dynamic performance inspection is achieved, the product quality is improved, the labor intensity is reduced, and production resource waste is avoided. The installation process is improved, and the adjustment efficiency and quality data accuracy are improved; in the installation process of an assembly site, all-working-condition installation data of the windshield wiper system can be checked, the measurement means is improved, and the adjustment precision is improved; all operation conditions of the windshield wiper are achieved through the motor train unit windshield wiper installation inspection device, and the installation quality is inspected through dynamic functionality.

Description

Technical field[0001]The invention relates to the technical field of EMU manufacturing, in particular to a wiper system installation method based on an EMU wiper installation inspection device.Background technique[0002]In the current EMU production process, the wiper system is positioned at the assembly site based on the size of the lower edge of the wiper blade and the right edge of the windshield glass of the cab. The wiper arm with the wiper fluid nozzle and the wiper in the wiper motor mechanism are positioned. The two connecting bolts of the arm drive mechanism are tightened, and the wiper arm pressure is adjusted according to 40Nm±2. However, due to the dimensional tolerances and differences in friction coefficients of the windshield glass of the EMU, problems such as the position deviation of the brush arm and the jitter of the brush arm often occur when the vehicle enters the commissioning site for functional tests. Once the above problems occur, it is necessary for the asse...
