Detailed description of the invention
Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 1 and Figure 2, the utility model comprises adjustable supports 1, bracing frame 2, stator supporting disk 3, rotor supports dish 4, guiding mechanism 5; The bottom surface of bracing frame 2 arranges adjustable supports 1; Bracing frame 2 upper surface is provided with stator supporting disk 3 to be used for supporting stator, is linked together by bolt and bracing frame 2; In the middle of bracing frame, governor motion 5 is set, for adjusting the assembly precision between rotor and stator; Described governor motion also can move by rotor driven vertically, facilitates the assembling of rotor upper level blade, in order to avoid gouge blade; ; Guiding mechanism is also provided with dial framework, and dial framework drives and detects table rotation; Rotor supports dish 4 is arranged on above stator supporting disk 3, for supporting whole rotor;
Described guiding mechanism comprises pull bar 6, positioning seat 7, connecting pin 8, list catenation seat 9, holding screw 1O, rocking bar 11, handle 12, rotating shaft 13, thread bush 14, table holder 15, cover 16, linear bearing 17, adapter sleeve 18, thrust bearing 19, fixed axis 2O, rotor supports dish 4 has three positioning seats 7, be uniformly distributed along the circumference, be used for locating the center of rotor one-level dish, the effect of pull bar 6 is strained and fixed by one-level dish after one-level dish adjustment assembly precision, keeps its assembly precision; Adapter sleeve 18 is connected with stator supporting disk 3 by bolt; Rotor supports dish 4 and fixed axis 20 utilize connecting pin 8 to link together, fixed axis 20 can rotor driven supporting disk 4 times, lower movement; Installed 2 linear bearings 17 between adapter sleeve 18 and fixed axis 2O lower end, the effect of linear bearing 17 makes fixed axis 20 move flexibly, reduces friction; The upper end of fixed axis 20 is fixed by holding screw 1O and thread bush 14 circumference, can rotate with thread bush 14; It is rotating shaft 13 in fixed axis 2O, rotating shaft 13 has installed rocking bar 11, rotating rocker 11, driven rotary axle 13 rotates, and because rotating shaft 13 is axially fixing, can not move axially, can only be that thread bush 14 drives fixed axis 20 to move vertically, in the bottom of rotating shaft 13, thrust bearing 19 is set, not only can supporting rotating shaft, also make rotating shaft 13 rotate more flexible; Be list catenation seat 9 outside fixed axis 20, table holder 15 screw and list catenation seat 9 are fixed, and are used for installing the table detecting and beat; Because table operationally needs circumferentially to rotate, handle 12 being installed by table holder 15, in order to reduce pivoting friction, in table holder 15, also having added the cover 16 that two have white lubricating function.
Using method of the present utility model is:
First adjust adjustable supports 1, eliminate the error existed because work ground is uneven, detect with horizon rule, assembling device is adjusted to level.Be put into after stator is sling on stator supporting disk 3, fix with bolt.Be put on rotor supports dish 4 by one-level dish, adjust the gap between itself and stator, after accomplishing fluently level, rotating rod 6, drives positioning seat 7 outwards movement, by fixing for one-level dish radial direction, keeps radial clearance tolerance between stator within ± 0.002 II II n.Rotating rocker 11, makes fixed axis 20 rotor driven supporting disk 4 rise, one-level dish is raised, in order to avoid gouge blade.After highly mixing up, start a grade blade is installed; After one-level blades installation is complete, rotating rocker 11, fixed axis 2O rotor driven supporting disk 4 is declined, until size L 1 position, one-level dish has assembled.Size L 1 is the difference in height between stator and one-level dish, has done axial limiting to fixed axis 20 when device is assembled, as long as drop to minimum, L 1 position will be reached, make simple to operate like this, convenient, reduce workman's detection time, improve efficiency of assembling, ensure that assembly precision simultaneously.Then secondary dish is assembled, detection table is arranged on table holder 15, and rotary handle 12 drives the table holder 15 on list catenation seat 9 to rotate, also drive table to rotate simultaneously, the height of adjustment form and position, with detecting the flatness of secondary dish and beating, also will detect the axiality of secondary dish and one-level dish, adjustment secondary dish, after each accurate values reaches matching requirements, fastening secondary dish, installs two grade blades; By that analogy, until complete the assembling of six grades of dishes and blade, whole low-pressure turbine has assembled.Rotating rod 6, drive positioning seat 7 to move inwards, the radial direction removing one-level dish is fixed, and the connecting bolt of dismantle stator and stator supporting disk, just can hang away low-pressure turbine, and whole assembling process is complete.
