Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment: as shown in Figure 1 to Figure 2, the utility model provides a kind of novel thyristor top-pressure mechanism, it is characterized in that, comprise disc spring push rod 1, axle sleeve baffle plate 2, locking nut 5 and mounting panel 7, it is characterized in that, described disc spring push rod 1 one end is sleeved in described mounting panel 7, and described disc spring push rod 1 is fixed by described locking nut 5 with described mounting panel 7 junction, the other end of described disc spring push rod 1 connects busbar 8, and the periphery of described disc spring push rod 1 has been set with disc spring 4, the outer race of described busbar 8 is provided with disc spring axle sleeve 3, and described busbar 8 side connects bolt 6 by crossed countersunk head screw 9, described axle sleeve baffle plate 2 is set on bolt 6.
Further, described disc spring push rod 1 uses 45# steel overall processing, and described disc spring push rod 1 forms an entirety by disc spring axle sleeve 3 and bolt 6 with described disc spring 4.
Further, one end of described locking nut 5 is connected with described mounting panel 7 by arranging annular small boss, and described locking nut 5 end face adopts C10 chamfering end face.
Disc spring push rod 1 is main load-carrying construction when hydraulic loading mechanism pressurizes, use 45# steel overall processing, structural strength is high, each installation face of cylinder axiality is better, the quality of fit avoiding common splicing structure is low, total device comprise disc spring, axle sleeve etc. coordinate be that concentricity is poor, the steady and problem of skewness of complex structure, pressurization., be integrally fixed by the push rod that four disc springs 4 are housed by top disc spring axle sleeve 3, busbar 8 and bolt 6, device globality is better, ensure that pressurized operation is safer, it is convenient to safeguard meanwhile.
Locking nut 5 major function is after the distortion of valve heap disc spring, push rod have moved axially pressurization, is maintained by institute's plus-pressure by the mode that nut is locked on a mounting board.New design locking nut 5 structure compares conventional hexagonal locking nut used when conventional valve heap pressurizes, one section adopts the face of cylinder directly to insert mounting panel 7 center mounting hole, leave annular small boss by the face of cylinder and ensure the precision-fit with installing hole on mounting panel 7, thus it is consistent to ensure that centre-height piled by jack unit center and thyristor radiator valve, guarantees pressure effect; Due to boss and installing hole contact internal walls limited area when pressurization, there is not the frictional force situation stuck when pressurizeing too greatly coordinated with installing hole; Clamping screw one end face adopts the end face of C10 chamfering, when press-fiting can under pressure with mounting panel 7 centre bore center auto-alignment
Disc spring 4 is pushed up laminated structure and external valve and is piled copper bar radiator etc. when being connected, first being fixed on by bolt by crossed countersunk head bolt 9 press-fits on copper bar, again it is fixed in first order radiator card by bolt entirety, jack unit can be carried out so easily coordinate with the installation that valve piles mounting blocks and radiator two ends, ensure radiator, thyristor center and jack unit center point-blank, realize valve to pile each components and parts center and unanimously do not rock, valve heap bulk strength improves.
Inside, disc spring axle sleeve 4 one end is processed with boss, can axis cover baffle plate 2 be bolted to push rod and limited with behind one end, prevent disc spring axle sleeve and disc spring from skidding off from push rod upper end, by the boss of disc spring push rod mid portion, above-mentioned parts is all limited simultaneously, become as a whole.The reliability of mechanism is ensured during pressurization.
During press-loading apparatus pressurization, mounting panel centre bore is goed deep in charger top, ensures pressurization top and the centering of disc spring push rod 1, ensures to press-fit operating efficiency and quality.
When installing and use this this Novel thyristor top-pressure mechanism, first need device overall package: disc spring push rod 1 bottom belt screw thread, above directly locking nut 5 being spun on.Then, four disc springs 4 are placed on the thicker top of disc spring push rod 1 diameter, subsequently disc spring axle sleeve 3 is enclosed within the upper of the disc spring 4 at push rod top, axle sleeve baffle plate 2 is fixed on disc spring push rod 1 top by the crossed countersunk head screw 9 of two M4*8 the most at last, restriction push rod top disc spring 4 does not outwards skid off with disc spring axle sleeve 3.Disc spring push rod 1 bottom belt screw thread one end is inserted in the installing hole of valve heap disc spring side after completing overall assembling.Then, the bolt 6 be fixed on by crossed countersunk head screw 9 on copper bar is directly inserted in disc spring push rod 1 top mounting holes, eventually through pan head screw, copper bar and radiator is fixed as a whole, complete the disc spring 4 of silicon stack and possess pressurized conditions.
During concrete pressurized operation, first stretch in mounting panel 7 centre bore by special hydraulic loading device top, on special top, processing can insert the alignment pin of disc spring push rod 1, puts into pressurization back-up block subsequently in the chute of mounting panel 7 both sides.During manual pressure, moving in the same direction in the pressure left and right, top that disc spring push rod 1 is subject to hydraulic means central ejector rod, forces disc spring 4 to deform.Until the pressure gauge display institute plus-pressure of hydraulic means arrived require time, stop pressurized operation, locking nut 5 is threaded to mounting blocks 7 central hole and uses frock spanner band tight by rapid craft, confirm tighten after by slow for hydraulic means pressure release, hydraulic means and pressurization bracing or strutting arrangement are removed after Pressure gauge display pressure is all laid down, the pressurization of whole valve heap completes.
The utility model provides a kind of novel thyristor top-pressure mechanism, adopt the higher disc spring push rod 1 of intensity to avoid the quality of fit of common splicing structure is low, total device comprise disc spring, axle sleeve etc. coordinate be that concentricity is poor, the steady and problem of skewness of complex structure, pressurization, overall construction intensity is high, associativity good, ensure that pressurized operation is safer, it is convenient to safeguard; It is consistent that new design locking nut 5 ensure that centre-height piled by jack unit center and thyristor radiator valve, guarantees pressure effect; Whole device not only difficulty of processing little, life-span long, easy to maintenance, and simplify the pressurization operation of thyristor valve heap, guarantee that pressure distribution is uniform.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
