AI Technical Summary
In the process of manufacturing gas turbine positioners, existing technologies are unable to achieve rapid positioning and repetitive positioning, resulting in the problem of multiple clamping and alignment.
A gas turbine positioner turning fixture including a positioning device and a clamping device was designed. The positioner is restricted by the base and positioning pins and fixed by bolts, pins and pressure plates. Combined with the alignment datum, it can achieve rapid positioning and multiple machining.
It enables rapid clamping and repeated positioning of both left and right structural locators, reducing the number of clamping and alignment operations and improving processing efficiency.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the field of gas turbine fixture, concretely relates to a gas turbine positioner turning fixture. BACKGROUND
[0002] The gas turbine positioner is one of the core components of the gas turbine and is an important component of the combustion chamber. The positioner is connected with the flame tube positioner bushing in a matched mode to fix the assembly position of the flame tube. The positioner is a special-shaped structure casting, and each type of gas turbine includes left and right positioners of two specifications. In the machining process of the positioner, a Stellite alloy sheet needs to be welded to the front cylindrical body of the positioner to ensure the strength of the assembly surface and prevent the flame tube from shaking due to wear during the operation of the gas turbine. The positioner needs to be turned twice. The first turning is to weld the Stellite alloy sheet, and the second turning is to process the positioner to the required size after stress relief heat treatment. The premise of turning the front section of the positioner is to ensure that the front cylindrical body of the product is located at the center of the fixture. SUMMARY
[0003] The utility model discloses a gas turbine positioner turning fixture which can quickly position and align the turning reference and realize repeated positioning and multiple processing.
[0004] A gas turbine positioner turning fixture includes a positioning device and a pressing device. The positioning device includes a base body and a positioning pin. The lower end of the base body is cylindrical, and the upper end is a profile boss processed according to the angle of the positioner. The positioner is placed on the tooling, and the positioning pin and the profile boss of the base body limit the position of the positioner. The pressing device includes a bolt pin and a pressing plate. After the positioner is placed in the tooling, the two bolt pins are connected with the base body to assist in fixing, and then the pressing plate is connected with the base body to press.
[0005] Further, the base body is provided with an alignment reference which is arranged on the base body base.
[0006] The utility model has the advantages that:
[0007] The utility model only needs to adjust the position of the positioning pin to meet the clamping and turning of the left and right positioners, and the positioner does not need to be clamped and aligned multiple times. BRIEF DESCRIPTION OF DRAWINGS

[0012] The utility model will be further described below with reference to the drawings.
[0013] As Figs. 1-3 shown, a gas turbine locator turning fixture, comprising a positioning device, a pressing device and an alignment reference, the positioning device 1 comprising a base body 4 and a positioning pin 5, the lower end of the base body 4 being cylindrical, the upper part being a profile boss processed according to the angle of the locator, ensuring that the positioning front-end cylinder is located at the turning processing position.
[0014] The locator is placed on the tooling, and the profile boss of the positioning pin 5 and the base body 4 limits the position of the locator, ensuring the uniqueness of the position.
[0015] The pressing device comprises a bolt pin 6 and a pressing plate 7, and after the locator is placed in the tooling, the two bolt pins 6 are connected with the base body 4 through threads for auxiliary fixing, and then the pressing plate 7 is connected with the base body 4 through bolts for pressing, so as to prevent the locator from moving during processing, and the alignment reference 3 is located on the base of the base body 4, and after the tooling is clamped, the machining reference is quickly determined by detecting the runout of the cylinder.
[0016] The positioning device 1 of the utility model has positioning parts, realizes the function of rapid positioning, the pressing device 2 has fixing parts, realizes the function of fixing parts during processing, the alignment reference 3 realizes the functions of repeated positioning of the locator and multiple processing.
[0017] The above only describes the preferred embodiments of the utility model and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
