Embodiment Construction

[0030] Examples such as Figure 1-3 As shown, the special device for rough and fine turning of gas turbine bearing seat includes base 1, facing pressure plate 2, side pressure plate 5, contour block 4, counterweight block 6 and hexagon socket bolts.

[0031] The base 1 provides a platform for the bearing seat M to be processed and the tooling. It is rigid enough to reduce the deformation of the bearing seat M to be processed; Find the correct efficiency.

[0032] The base 1 is a disk-shaped base, and the side pressure plate 5 is fixedly connected to the position of the disk surface of the base 1 near the outer edge of the disk surface. The number of the side pressure plates 5 is two, and the two side pressure plates 5 are arranged symmetrically along the axis of the base 1.

[0033] Each side pressure plate 5 includes two oppositely arranged first right-angle pressure plates 7, a first transverse pressure plate 8 is fixedly connected between the two first right-angle pressure...

Abstract

The invention discloses a special device for rough and finish turning of a gas turbine bearing base. The device comprises a base; and the base is fixedly connected with two side pressing plates for fixing bosses on two sides of a bearing base to be machined. The device has the beneficial effects of improving the workpiece machining quality and machining efficiency, effectively accelerating the workpiece rotating speed, accelerating the cutting speed by above 55%, improving the surface machining quality and machining precision to a certain extent and controlling the finish-turned inner hole precision within 0.01 mm.

Description

technical field [0001] The invention relates to a special device for rough and fine turning of bearing seats of gas turbines, which is used for rough and fine turning of bearing seats of various types of gas turbines. Background technique [0002] In the turning process of the gas turbine bearing seat, due to the irregular shape of the workpiece, centrifugal force will be generated during the rotation process, resulting in poor machining accuracy of the inner diameter; the clamping and alignment of the bearing seat is difficult, and the general clamping tool is difficult to achieve; Clamping is time-consuming and labor-intensive, not only inefficient, but also difficult to guarantee the precision requirements of the processed workpiece. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tool that can not only facilitate the clamping and alignment of the workpiece, but also facilitate the rapid adjustment of the di...
