Abstract

The utility model provides a cutting machining fixture of a turbine rotor shaft groove. The cutting machining fixture of the turbine rotor shaft groove guarantees rigidity of the turbine rotor shaft, effectively prevents bending deformation of the turbine rotor shaft in the machining process, and improves machining precision of the turbine rotor shaft. The cutting machining fixture of the turbine rotor shaft groove comprises a clamping flexible claw, and a copper sleeve is arranged on the clamping flexible claw. The cutting machining fixture of the turbine rotor shaft groove is characterized in that the copper sleeve stretches out of the end face of the clamping flexible claw, a locating rod is arranged on a cutting knife, and a locating block is arranged on the position, corresponding to the locating rod, of a rack.

Description

The clamp for cutting of turbine rotor axial trough
Technical field
The utility model relates to the technical field of workpiece positioning clamp, is specially a kind of clamp for cutting of turbine rotor axial trough.
Background technology
In the cutting technology of turbine rotor groove; turbine rotor will be installed the location; see Fig. 1; existing anchor clamps locate mode for first by top turbine rotor shaft is held out against after; adopt the again clamping of 1 pair of turbine rotor shaft tool setting point of soft pawl; the location that has guaranteed turbine rotor shaft clamps; 2 turbine rotor shafts that process of recycling copper sheathing protect; guaranteed the crudy of turbine rotor shaft; because it is oversize that copper sheathing can not stretch out soft pawl; affect feed; but the diameter of axle of turbine rotor shaft is thinner, and longer, copper sheathing stretch out soft pawl too weak point can have influence on the rigidity of turbine rotor shaft; cause turbine rotor shaft in processing flexural deformation, affected the machining accuracy of turbine rotor shaft.
Summary of the invention
For the problems referred to above, the utility model provides a kind of clamp for cutting of turbine rotor axial trough, has guaranteed the rigidity of turbine rotor shaft, prevents that effectively turbine rotor shaft from processing flexural deformation, having improved the machining accuracy of turbine rotor shaft.
Its technical scheme is such: a kind of clamp for cutting of turbine rotor axial trough, it comprises the soft pawl of clamping, be provided with copper sheathing on the soft pawl of described clamping, it is characterized in that: described copper sheathing stretches out the soft pawl end face of described clamping, be provided with backstay on the cutter, corresponding described backstay is provided with locating piece on the frame.
In the said structure of the present utility model, because stretching out, copper sheathing clamps soft pawl end face, be provided with backstay on the cutter, corresponding backstay is provided with locating piece on the frame, and copper sheathing stretches out and clamps soft pawl end face, guaranteed the rigidity of turbine rotor shaft, prevent that effectively turbine rotor shaft from processing flexural deformation, having improved the machining accuracy of turbine rotor shaft, be provided with backstay on the cutter, corresponding backstay is provided with locating piece on the frame, has guaranteed the security of feed.
Description of drawings
Fig. 1 is the clamp for cutting master TV structure figure of existing turbine rotor axial trough;
Fig. 2 is the main TV structure figure of the clamp for cutting of the utility model turbine rotor axial trough.
The specific embodiment
See Fig. 2; a kind of clamp for cutting of turbine rotor axial trough; it comprises the soft pawl 1 of clamping, clamps on the soft pawl 1 and is provided with copper sheathing 2, and copper sheathing 2 stretches out and clamps soft pawl end face 3; be provided with backstay 5 on the cutter 4; corresponding backstay 5 is provided with locating piece 7 on the frame 6, and turbine rotor shaft 8 is placed on (copper sheathing 2 plays a part protection turbine rotor shaft 8 machined surfaces) in the chuck 9 by copper sheathing 2, and top 10 withstand turbine rotor shaft 8; clamp by clamping soft pawl 1, realized that the location of turbine rotor shaft 8 clamps.
