Description
Technical field
The utility model relates to a kind of high-pressure turbine blade clamping device, after blade spreading, especially carries out profile add easy to operate fixture in man-hour.
Background technology
High-pressure turbine blade is the core component of engine most critical, has a direct impact the thrust-weight ratio, working life etc. of engine.Blade adopts axial dovetail configuration to be connected with wheel disc, makes opposing seal formula move with outer casing, can cause blade and the contact wear of obturaging, cause blade tip to wear and tear, must carry out spreading reparation to blade tip under the centrifugal action that High Rotation Speed produces.Spreading reparation and the processing of the profile after repairing all need to clamp blade, locate, and require blade tenon firm grip, blade tip locus is fixed and is easy to Repair gene.General clamping device, for ensureing that firm grip adopts blade tenon and blade tip two ends fixed form usually, uses the servicing units such as servo cylinder to realize by multistage adjusting knob acting in conjunction.Its weak point is complex structure, and blade tip can not be carried out Repair gene by holder, and complex operation, wastes time and energy.
Summary of the invention
Can not to the deficiency of blade tip position Repair gene, complex structure and complex operation for overcoming general clamping device, the utility model provide a kind of structure simple, easy to operate, clamp reliable and stable clamping device.
The technical solution adopted in the utility model is: a kind of high-pressure turbine blade profile processing fastening clamp device, there is the pedestal that is shaped with rectangular through-hole, it is characterized in that: be shaped with in rectangular through-hole upper end clamping high-pressure turbine blade 1) tight power open slot 2, rectangular through-hole lower end is shaped with to be communicated with downwards runs through slotted eye 4 open seam, and the longitudinal end face screw screw by pedestal one end clamping limb 3 of fastening screw 8 being equipped with fastening adjustment joystick knob 7 is connected the other end clamping limb 3 of pedestal with rectangular through-hole.
The utility model has following beneficial effect compared to prior art.
The utility model utilizes the elastic stress effect of tight power open slot 2 clamp material self of pedestal rectangular through-hole upper end, clamping blade tenon, can ensure that clamping is firm, not only blade tip position does not need clamping, and clamping device structure simple, be convenient to machined, clamp reliable and stable.Utilize rectangular through-hole lower end to be shaped with to be communicated with downwards and run through slotted eye 4 open seam elongated hole and run through groove, when being with tight tightening knob to fix tenon, clamping limb can not occur bending and deformation.
The utility model adopts the longitudinal end face screw screw by pedestal one end clamping limb 3 of the fastening screw 8 being equipped with fastening adjustment joystick knob 7 to be connected the other end clamping limb 3 of pedestal with rectangular through-hole, only needs low-force reliablely and stablely can fix high-pressure turbine blade 1 tenon.Because of chucking power be mainly derived from elongated hole run through groove distortion produce active force, clamping device agent structure only needs disposable Linear cut to complete machined, and structure is simple.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the organigram of the utility model pressure turbo blade profile processing fastening clamp device first embodiment.
Fig. 2 is the profile of Fig. 1 fastening clamp device.
Fig. 3 is the organigram of the utility model second embodiment.
1. high-pressure turbine blades in figure, 2 tight power open slots, 3 clamping limbs, 4 run through groove, 5 fixed card slots, 6 pedestals, 7. fastening adjustment joystick knob, 8 fastening screws, 9 pins, 10 pressure handles.
Detailed description of the invention
In Fig. 1, Fig. 2, the utility model fastening clamp device has the pedestal 6 that is shaped with rectangular through-hole, and pedestal 6 is main bodys of clamping device, and rectangular through-hole can be, but not limited to be rectangular through-hole, also can circular hole or elliptical aperture.The tight power open slot 2 of clamping high-pressure turbine blade 1 is shaped with in rectangular through-hole upper end.Tight power open slot 2 is clamp systems of clamping vane tip bare terminal end, and notch two ends are shaped with circular arc flange.Rectangular through-hole lower end is shaped with to be communicated with downwards runs through slotted eye 4 open seam, to increase tight power open slot 2 elastic acting force.The longitudinal end face screw screw by pedestal one end clamping limb 3 of fastening screw 8 being equipped with fastening adjustment joystick knob 7 is connected the other end clamping limb 3 of pedestal with rectangular through-hole.Fixed card slot 5 is shaped with in longitudinal both sides of pedestal 6.
When carrying out blade clamping, first clamping device fixed card slot 5 is put into blade spreading or profile process equipment to fix, again high-pressure turbine blade 1 tenon is put into tight power open slot 2, rotational fastener adjusting knob handle 7, the tight power open slot 2 of gripping apparatus grips vane tip is closely cooperated with high-pressure turbine blade 1 tenon groove, and band tightly consolidates adjusting knob handle 7 until high-pressure turbine blade 1 tenon is fixed.The mounting means of clamping device is as follows: clamping device pedestal 6 is put into blade spreading or profile process equipment, fixed card slot 5 is pushed down with pressing plate, fix pedestal 6, again high-pressure turbine blade 1 tenon is put into vane tip bare terminal end 2, ensure that high-pressure turbine blade 1 tenon and vane tip bare terminal end are fitted, then rotational fastener adjusting knob handle 7, clamping high-pressure turbine blade 1 tenon.After clamping, with hand moving vane blade tip, namely blade does not shake proves that blade clamps.If there is gentle agitation can continue to screw fastening adjustment joystick knob 7 until the clamping of high-pressure turbine blade 1 tenon.Clamping device is got except mode is as follows: first unclamp fastening adjustment joystick knob 7, takes off high-pressure turbine blade 1, then unclamps the pedestal 6 that pressing plate removes clamping device.
In an alternative embodiment as shown in fig. 3, the another kind of pressure handle tightening structure adopting and run through the fastening clamp device of groove function is described.Fastening adjustment joystick knob 7 has mainly been changed into the pressure handle 10 assembled by pin 9 by this structure; Change fastening screw 8 and the matching thread end of former fastening adjustment joystick knob into logical excellent polished rod.Add and coordinate pin 9 between pressure handle 10 with fastening screw 8.Pressure handle 10 head, by its eccentric orfice, makes pressure handle 10 press down the logical excellent polished rod of tension in process, thus drives the tight power open slot 2 of clamping device, clamping blade top bare terminal end.Driving clamping limb 3 by pressure handle 10 being pressed to upright position, realizing the effect of clamping blade tenon.This structure has advantage easy and simple to handle.
Professional and technical personnel in the field, according to above-mentioned disclosed fastening clamp device, can realize or use the utility model.It will be apparent for running through the multiple amendment of groove Functional Design to those skilled in the art according to the utility model.Therefore the utility model can not be restricted to specific embodiment disclosed herein, but will meet the most wide region consistent with running through groove function.
