Description
TECHNICAL FIELD
[0001] The utility model belongs to the field of gas turbine manufacturing, concretely relates to a low pressure static vane ring plate rivet hole drilling die. BACKGROUND
[0002] The gas turbine is with air as medium, relies on the air suction of compressor and carries out the continuous compression to the air, the compressed air enters the combustion chamber with the fuel mixture, the pressure surges. The high temperature and high pressure gas is ejected from the combustion chamber, one hand promotes the compressor to compress the air to carry on the thermodynamic cycle, one hand promotes the turbine blade to do the work. The whole process is a transformation from the heat energy and potential energy of gas (fuel) to kinetic energy. Since the static vane ring is very common in the assembly of gas turbine and aeroengine, needs to bear several hundred degrees of high temperature and air flow pressure in the working process of compressor, and the high temperature, high corrosive working environment makes the self characteristic of static vane ring itself require higher. At present, the plate rivet hole on the inner ring of low pressure static vane ring belongs to inclined plane hole processing, needs to be processed in five-axis machining center, and it is more time-consuming and laborious. Since the precision requirement is not high, a kind of quick and simple drilling die device is needed to assist processing. SUMMARY
[0003] The utility model provides a low pressure static vane ring plate rivet hole drilling die.
[0004] A low pressure static vane ring plate rivet hole drilling die, including positioning plate, bottom plate, cylindrical pin and jackscrew, the positioning plate and bottom plate upper end are connected through cylindrical pin and are fixed through screw, the positioning plate and bottom plate lower end are processed as notch, and the bottom plate is equipped with jackscrew.
[0005] Further, the positioning plate, bottom plate and cylindrical pin are all made of bearing steel Gcr15 material and are subjected to heat treatment quenching and surface blackening treatment.
[0006] The utility model has the advantages that the utility model utilizes the inner ring inner side outer diameter size and wire cutting notch to be positioned, uses the form of clamping plate to be fixed on the inner ring with the aid of jackscrew, and is drilled through guide hole. Mainly play the function of drilling guide aid, not only save the processing cost of machine tool, also improve the processing efficiency. BRIEF DESCRIPTION OF DRAWINGS
[0007] Fig. 1 It is the overall structural drawing of the utility model;
[0008] Fig. 2 It is the structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0009] The utility model will be further described below in connection with the drawings.
[0010] AsFigs. 1-2 As shown in the drawing, a low-pressure static vane ring plate rivet hole drill jig comprises a positioning plate 1, a bottom plate 2, a cylindrical pin 4 and a top wire 5; the positioning plate 1 and the bottom plate 2 are connected through the cylindrical pin 4 at the upper end and are fixed through a screw; the lower end of the positioning plate 1 and the bottom plate 2 is processed into a notch, and the bottom plate 2 is provided with the top wire 5. All non-standard parts are made of bearing steel Gcr15 material and are subjected to heat treatment quenching and surface blackening treatment.
[0011] The working principle of the utility model is as follows: the low-pressure static vane ring is placed on the working platform, the plate rivet hole drill jig is positioned and installed on the inner ring with the inner diameter of the inner ring and the wire cutting notch as the positioning, the drill jig is fixed with the inner ring through the self-provided fixed top wire, the inner ring is drilled at the inclined surface through the hand drill along the guide hole after the drill jig is fixed.
[0012] The utility model adopts the clamping plate mode and positions and clamps with the inner ring size, has the characteristics of simple and convenient installation, firm fixing mode, simple and stable processing, not only saves the processing cost of using five-axis machine tool, but also greatly improves the processing efficiency under the premise of ensuring the accuracy of manual drilling.
