Embodiment Construction

[0020] Below in conjunction with accompanying drawing, patent of the present invention is described in detail:

[0021] Such as figure 1 , figure 2 As shown, the present invention is made up of cutter bar 1, angle adjustment unit 2, adjustment locking unit 3, groove cutter 4, three compression screws 5, and described groove cutter 4 is the outsourcing standard groove cutter, is characterized in that: The cutter bar 1 described above has a chute at the end, and the positioning angle θ at which the slot cutter 4 is clamped on the cutter bar 1 is determined by the angles α and β on both sides of the chute on the inner circle of the workpiece, θ=α+(β -α) / 2, α is the angle of the side with a small slope of the groove on the inner circle of the workpiece, and β is the angle of the side with a large slope of the groove on the inner circle of the workpiece; three screws are arranged at the tool bar 1 to clamp the groove cutter 4 The angle adjustment unit 2 and the adjustment lockin...

Abstract

The invention relates to an angle-adjustable inner circle helical tooth and chute machining device. Structurally, a chute is formed in the end of a cutter rod, three screw holes are formed in a cutter rod clamping groove cutter, and the cutter rod is provided with an angle adjusting unit and an adjusting locking unit; and after the angle is adjusted, a locking screw of the adjusting locking unit is screwed and presses and fixes the angle adjusting unit, the groove cutter is closely attached to the positioning plane of a positioning plate of the angle adjusting unit for positioning, the groove cutter is pressed through two pressing screws close to the cutter rod clamping groove cutter, and the positioning plate of the angle adjusting unit is fixed to the cutter rod by screwing three pressing screws. Installing and using are convenient and fast, positioning is stable, the angle correction is adjusted within the angle adjusting range allowed by the device through a meshing gear pair of the angle adjusting unit, and reliable, convenient and efficient machining of the inner circle chute and helical teeth can be effectively guaranteed due to high precision of numerical control equipment. The device is easy and convenient to install and operate, and the requirement for the skill level of operators is low. The labor intensity of the operators is low during online machining.

Description

technical field [0001] The invention relates to an angle-adjustable inner circle helical gear and chute groove processing device, which can be widely used in the processing of rotary workpieces with helical teeth and chute grooves in the inner circle, and can be installed on a horizontal or vertical numerical control lathe. The angle adjustment unit installed on the tool bar adjusts and corrects the clamping angle of the groove cutter to be consistent with the angle of the processed inner circular chute, and the CNC program input into the CNC lathe controls the tool machining track to complete the processing of the inner circular helical teeth and chute. Background technique [0002] A steam turbine has two parts, the stator and the rotor. When working, the rotor rotates at high speed and the stator is fixed, so a certain gap must be maintained between the rotor and the stator to prevent mutual friction. When the steam flows through the various stages of the steam turbine, ...
