[0023] Before detecting the trolley, it is necessary to measure whether the center distance of the two ends of the track is the same, and the center distance error of the two ends should be kept within ±1MM. The diagonal lines of the track of the vehicle detection frame 1 are measured to ensure that the measurement data is the same, and the diagonal line difference of the two ends of the detection guide rail 4 should be kept within ±2MM.

[0024] When measuring the assembly precision of the RGV trolley:

[0025] 1. Measure the concentricity of the trolley drive shaft. Measurement method: measure the outermost size of the trolley drive shaft from the track end, and compare whether the sizes of the two ends of the drive shaft are consistent, and the error is within ±1MM.

[0026] 2. Measure whether the wheels are parallel to the track. Measurement method: through the irradiation of two groups of light emitting photoelectric, whether the light spot receiving is normal, and the deviation range should be ensured to be positive and negative 0.5MM.

[0027] Specifically, the bottom of the adjusting seat 7 is provided with a limiting block 8, and the top of the adjusting seat 7 is connected with a connecting plate 9. The top of the chassis cross beam 2 is provided with a mounting guide groove 16, and the surface of the limiting block 8 is slidably connected to the inner wall of the mounting guide groove 16.

[0030] Further, the reference guide rail 13 is a structure for assembling the light detection device 6, and also serves as a carrier for the RGV vehicle, so that the RGV vehicle can be detected on the detection device and also serves as a carrier. At the same time, the light detection device 6 is convenient to install, and the running wheels 15 on both sides of the trolley frame 14 are detected by the light detection device 6. The fixed baffle 5 is mounted on the end of the reference guide rail 13, and can detect the concentricity of the running wheels 15.

[0031] The reference guide rails 13 are arranged in parallel, and the spacing of the reference guide rails 13 is matched according to the wheel spacing of different models of vehicles. One end of the reference guide rail 13 is a reference detection end, and the fixed baffle 5 is fixed to the end. When detecting the coaxiality of the vehicle, the end face of the fixed baffle 5 is used as the measurement reference. After the reference guide rail 13 is installed, the parallelism and the end reference of the reference guide rail 13 need to be calibrated.

[0032] Whether the center distance of the two ends of the measuring track is the same, the center distance error of the two ends should be kept within ±1MM. Measurement method: measure the length of the same side of the two tracks. Measure the diagonal lines of the two tracks, and the difference between the diagonal lines of the two ends should be kept within ±2MMM. Measurement method: measure the same point of the two tracks.
