specific Embodiment approach 1

[0008] Specific implementation mode 1: Combination Figure 1-Figure 5 Explain that a clamping dual-purpose tool holder for flat-rotating disk processing in this embodiment includes a cylinder 1, an octahedron 2, two connecting bodies 3, and two shank keys 4;

[0009] The cross-sectional shape of the shank key 4 is a waist shape, the longitudinal section of the connecting body 3 is a T-shape, the octahedron 2 is a longitudinal cross-sectional shape of an octahedron with a rectangular upper end and an isosceles trapezoid at the lower end, etc. The long base side of the waist trapezoid is coplanar with the long side of the rectangle. The cylinder 1 has round holes 1-2 along its axial direction from one end face to the radial center line MN. The round holes 1-2 are used for installation. Tool holder, the cylinder 1 is machined with rectangular holes 1-5 along its axial direction from the other end surface to the radial center line MN. The rectangular holes 1-5 are used to install the...

Abstract

The invention provides a mounting and clamping dual-purpose knife set for facing head machining, especially for the machining of a facing head of an inner die cavity of an assembly of a steam turbine, in order to solve the problems of the existing knife set for machining the inner cavity of the assembly of the steam turbine, such as failure in universality, poor adaptability and difficulty in machining of the inner die cavity of the assembly of the steam turbine. The mounting and clamping dual-purpose knife set provided by the invention comprises a cylinder, an octahedron, two connecting bodies and two handle keys, the cylinder is provided with a round hole in the axial direction on one side from one end face to a center line, the cylinder is provided with a rectangular hole in the axial direction on one side from the other end face to the midperpendicular, the cylinder and the octahedron are integrated into a whole, the two connecting bodies are arranged on the lower end face of the octahedron in parallel, the octahedron and the two connecting bodies are integrated into a whole, the lower end face of the octahedron between the two connecting bodies is provided with two handle keys in parallel in the axial direction of the cylinder, and the two handle keys are connected with the octahedron. The mounting and clamping dual-purpose knife set is used for facing head machining.

Description

Technical field [0001] The invention relates to a clamping dual-purpose tool sleeve used for processing the inner cavity of a part sleeve of a steam turbine. Background technique [0002] The shape and structure of the part sleeve of the steam turbine are complicated, and some processes require turning. However, due to the shape and structure of the workpiece, it cannot be processed on a lathe. The only option is to use a flat-rotating disk attachment on a boring and milling machine. The flat-rotating disk processing is better than a lathe Machining has its advantages. The lathe uses the workpiece to rotate and the tool performs linear movement to complete the machining. The cutting speed cannot be very large and there are limitations. In the case of boring and milling machines, the workpiece does not move. The tool moves linearly while rotating at high speed to complete the turning processing of the profile. The high-speed rotation of the tool for flat-rotation processing is hig...
