[0002] The slant bed CNC lathe is a high-precision and high-efficiency automated machine tool. Equipped with a multi-station turret or a power turret, the machine tool has a wide range of process performance and can process linear cylinders, oblique cylinders, arcs and various complex workpieces such as threads, grooves, and worms. It has various compensation functions such as linear interpolation and circular interpolation, and has played a good economic effect in the mass production of complex parts. The plane where the two guide rails of the slant bed CNC lathe are located intersects with the ground plane to form an inclined plane with angles of 30°, 45°, 60°, and 75°. The bed of the slant bed CNC lathe is a right triangle. Obviously, under the same guide rail width, the X-direction slide of the slant bed is longer than that of the flat bed. The practical significance of its application in the lathe is that more tool positions can be arranged. The cross-sectional area of ​​the slant bed CNC lathe is larger than that of the same specification flat bed, that is, it has stronger anti-bending and anti-torsion capabilities.

[0003] When processing the linear rail surface of a CNC lathe with an inclined bed, the linear rail surface and the spindle of the machining center need to remain perpendicular to ensure the accuracy of the linear rail surface. Due to the complex structure of the inclined bed, the existing fixture cannot quickly position the inclined bed and cannot ensure that the linear rail surface and the spindle remain perpendicular, which affects the machining accuracy and has low clamping efficiency. The operator needs to adjust the fixture many times, which consumes a lot of physical energy. Utility Model Content

The 60-degree support seat is a straight triangular prism with a hollow interior. The side surface where the hypotenuse is located has an angle of 60 degrees with the ground, and the bevel is evenly distributed with a number of threaded holes, the threaded holes are perpendicular to the bevel, and an adjusting push rod is installed in the threaded hole. There are a number of pads A on the bevel. The 30-degree support seat is a straight triangular prism with a hollow interior. The side surface where the hypotenuse is located has an angle of 30 degrees with the ground, and the bevel is evenly distributed with a number of threaded holes, the threaded holes are perpendicular to the bevel, and a number of pads B are fixed on the bevel by screws. The 60-degree support seat and the 30-degree support seat have a flange on the side in contact with the workbench, and are fixed to the milling machine workbench through the flat plate A, the pillar A, and the T-block.

[0006] Preferably, the 60-degree support seat and the 30-degree support seat are manufactured by a casting process and are formed by precision milling.

The 60-degree support seat and the 30-degree support seat are used to support the inclined bed. The processing angle of the inclined bed is adjusted. The inclined bed is adjusted to the point where the linear rail surface is perpendicular to the main axis. The two sides of the inclined bed are processed to form a process reference surface, which is fitted with the 60-degree support seat and the 30-degree support seat. Before use, according to the size of the inclined bed, multiple groups of 60-degree support seats and 30-degree support seats can be selected to provide support for the inclined bed to ensure that the inclined bed is balanced in force.
