Abstract
The utility model provides a gas turbine dovetail tenon profile measuring tool location structure, dovetail tenon profile measuring tool location structure constitute as follows: the device comprises a base 1, a left positioning block 2, an ejector rod 3, a locking handle 4, an eccentric shaft 5, a tenon positioning pin 6, a right positioning block 7, a gasket 8, a hexagon nut 9 and an inner hexagon screw 10.
Description
Technical Field
The utility model relates to a measuring tool's location structural design and application technical field, in particular to gas turbine dovetail type tenon profile measuring tool location structure.
Background
In the manufacturing process of the gas turbine blade, a profile measuring tool is basically adopted to detect a blade profile curve, profile allowance and basin back offset, a blade tenon is usually adopted for positioning, most of the existing dovetail tenon positioning structures adopt a mode of positioning one side of a tenon profile and pressing the other side of the tenon profile, and due to the deviation generated by actual manufacturing, a blade profile central line can generate certain offset in the detection process and cannot be always positioned at the center of the measuring tool, so that the detection is deviated, the rework and repair of a large number of blades are caused, manpower and material resources are greatly wasted, and the production period is prolonged.
People hope to obtain a gas turbine dovetail tenon profile measuring tool positioning structure with excellent technology and reliable positioning.
Disclosure of Invention
The utility model aims at providing a gas turbine dovetail tenon profile surveys utensil location structure solves the dovetail tenon profile and surveys the problem that the utensil location produced the skew.
The dovetail tenon profile measuring tool positioning structure comprises the following components: the device comprises a base 1, a left positioning block 2, an ejector rod 3, a locking handle 4, an eccentric shaft 5, a tenon positioning pin 6, a right positioning block 7, a gasket 8, a hexagon nut 9 and an inner hexagon screw 10; the left positioning block 2 is fixed on the base 1 through an inner hexagon screw; the ejector rod 3 is positioned in the base 1; the eccentric shaft 5 is positioned in the base 1 and connected with the ejector rod 3; the tenon positioning pin 6 is fixed on the base 1 in an interference fit manner; the right positioning block 7 is fixed on the base 1 through an inner hexagon screw; the gasket 8 is fixed on the eccentric shaft 5 through a hexagon nut 9; the locking handle is fixed on the eccentric shaft 5 through threads.
The dovetail tenon is positioned by a left positioning block 2 and a right positioning block 7 to limit the rotation of the blade; the dovetail tenon is positioned by a tenon positioning pin 6 to limit the movement of the blade.
The eccentric shaft 5 rotates to drive the ejector rod 3 to move back and forth to clamp the blade tenon, and the left positioning block 2 and the right positioning block 7 are of a symmetrical structure, so that the blade profile center line can be ensured to be positioned at the center of the positioning structure of the measuring tool all the time without deflection.

The invention is further described below with reference to the accompanying drawings.
FIG. 1 is a schematic structural diagram of a dovetail profile measuring tool positioning structure of a gas turbine.
FIG. 2 is a cross-sectional view of a dovetail profile measuring tool positioning structure of a gas turbine.
Wherein: 1-a base; 2-a left positioning block; 3-a top rod; 4-locking a handle; 5, eccentric shaft; 6-tenon positioning pin; 7-right positioning block; 8-a gasket; 9-hexagonal nut; 10-socket head cap screw.
Detailed Description
According to the attached drawings, the dovetail tenon profile measuring tool positioning structure comprises the following components: the device comprises a base 1, a left positioning block 2, an ejector rod 3, a locking handle 4, an eccentric shaft 5, a tenon positioning pin 6, a right positioning block 7, a gasket 8, a hexagon nut 9 and an inner hexagon screw 10; the left positioning block 2 is fixed on the base 1 through an inner hexagon screw; the ejector rod 3 is positioned in the base 1; the eccentric shaft 5 is positioned in the base 1 and connected with the ejector rod 3; the tenon positioning pin 6 is fixed on the base 1 in an interference fit manner; the right positioning block 7 is fixed on the base 1 through an inner hexagon screw; the gasket 8 is fixed on the eccentric shaft 5 through a hexagon nut 9; the locking handle is fixed on the eccentric shaft 5 through threads.
The dovetail tenon is positioned by a left positioning block 2 and a right positioning block 7 to limit the rotation of the blade; the dovetail tenon is positioned by a tenon positioning pin 6 to limit the movement of the blade.
The eccentric shaft 5 rotates to drive the ejector rod 3 to move back and forth to clamp the blade tenon, and the left positioning block 2 and the right positioning block 7 are of a symmetrical structure, so that the blade profile center line can be ensured to be positioned at the center of the positioning structure of the measuring tool all the time without deflection.
This embodiment dovetail tenon profile measuring tool location structure has solved the problem that dovetail tenon blade profile central line and profile measuring tool center offset, and measuring blade profile curve, profile surplus and basin back of the body offset that can be accurate, actual operation is convenient, swift to it is with low costs.
