[0003] The fixture for machining the base in this application is used on the aforementioned horizontal lathe for clamping parts used in the bottle-making machine: base 21. The horizontal lathe processes the base 21, as shown in the image. Figure 1 As shown, the base 21 includes main structures such as the shaft cylinder 2103. The shaft cylinder 2103 has a large opening slot 2102 on one side and a small opening slot 2101 on the other side. When the axial length of the base 21 is long, it is easy to wobble when using horizontal machining, and the holes at both ends and the small opening slot 2101 are prone to deformation. Ordinary fixtures cannot meet the requirements of coaxiality of the holes at both ends and no deformation at the opening slot. Utility Model Content

The base 1 and the support 3 are provided with hydraulic oil circuits for supplying oil to the three clamping hydraulic cylinders.

[0024] The base 1 is also provided with a support arm, an auxiliary support arm, a positioning structure and a limiting structure. The support arm, the auxiliary support arm and the positioning structure are arranged crosswise on the base 1 along the axis of the base 21. The positioning structure is provided with a vertical positioning block and a horizontal positioning block 14. The functional end of the vertical positioning block is set towards the large opening slot 2102 of the base 21. The functional end of the horizontal positioning block 14 is set opposite to the limiting structure, and the horizontal positioning block 14 and the limiting structure are set at both ends of the large opening slot 2102.

[0025] Specifically, the orientation of the base 1 is defined by its top, bottom, left, right, front, and back. The base 21 is placed on the fixture, with the small opening slot 2101 facing the rear and the large opening slot 2102 facing the front. When the first clamping arm 7 and the third clamping arm 9 clamp the housing 2105 and the shaft cylinder 2103 respectively, the small opening slot 2101 is located between the two support seats and is pressed against the upper end of the side wall of the small opening slot 2101 by the second clamping arm 8, effectively preventing deformation of the small opening slot 2101 during processing.

[0026] The first clamping hydraulic cylinder 4 and the third clamping hydraulic cylinder 6 are at the same height, while the second clamping hydraulic cylinder 5 is lower than the height of the first clamping hydraulic cylinder 4 and the third clamping hydraulic cylinder 6, in order to avoid the machining tool of the small opening slot 2101.
