The photometric and spectroscopic data for three double-lined detached eclipsing binaries were collected from the photometric and spectral surveys. The light and radial velocity curves of each binary system were simultaneously analyzed using Wilson-Devinney (WD) code, and the absolute physical and orbital parameters of these binaries were derived. The masses of both components of ASASSN-V J063123.82+192341.9 were found to be M₁ = 1.088 ± 0.016 and M₂ = 0.883 ± 0.016 M_☉; those of ASAS J011416+0426.4 were determined to be M₁ = 0.934 ± 0.046 and M₂ = 0.754 ± 0.043M_☉; and those of MW Aur were derived to be M₁ = 2.052 ± 0.196 and M₂ = 1.939 ± 0.193 M_☉. Finally, the evolutionary status of these detached binaries was discussed based on their absolute parameters and the theoretical stellar models.
