[0012] The present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0013] A kind of Figure 1-2 The four-axis machining fixture for the door lock component shown includes a rotating shaft connecting plate 1 and a fixture base plate 2. The fixture base plate 2 is vertically arranged on the rotating shaft connecting plate 1. A reinforcing diagonal support block 11 is arranged between the rotating shaft connecting plate 1 and the fixture base plate 2, thereby ensuring the structural strength of the fixture. A positioning seat 3 is provided on the fixture base plate 2, and a clamping device 4 is provided in the opposite direction of the positioning seat 3 for positioning and clamping the door lock component. An auxiliary support block 5 is provided on the positioning seat 3, and the auxiliary support seat 5 is used to prevent the door lock component from rotating. The auxiliary support seat 5 is also used to provide auxiliary support for the side when the side of the workpiece is processed, thereby ensuring that no deformation occurs during the machining process. The positioning seat 5 has a cylindrical positioning boss 6, and a plurality of equal-height support platforms 7 are distributed annularly on the lower outer periphery of the cylindrical positioning boss 6. The number of equal-height support platforms 7 is at least three, thereby providing a plane for positioning the door lock component. Auxiliary support block 5 is mounted on the top surface of cylindrical positioning boss 6. A side surface of the auxiliary support block 5, perpendicular to the radial direction of cylindrical positioning boss 6, serves as an auxiliary support surface 9. This surface is equipped with multiple relief grooves 10, ensuring effective support for the door lock surface and ensuring machining accuracy. The top surface of cylindrical positioning boss 6 is provided with multiple hollowed-out holes 8 extending through the fixture base plate 2. These holes allow a machine tool's tool to penetrate the interior of the door lock component and perform reverse machining on the internal end surface.
