Abstract
The utility model provides a turbomachine web clamp including a base, a pillar, an upper disc, a positioning ring, and a pressing hook. The upper disc is fixed on the base via the pillar, the positioning ring and the pressing hook are fixed on the upper disc, and the pressing hook determines the direction of the hook via a pin. The turbomachine web clamp is characterized in that an expansion clamp body is fixed on the axis of the upper disc, an inclined plane expansion bolt is arranged on the expansion clamp body, an inclined plane expansion ring is sleeved on the inclined plane expansion bolt, a gland is arranged at the upper end of the inclined plane expansion bolt, a positioning side block is arranged between the gland and the expansion clamp body, and the inner end of the positioning slide block is tightly attached on the inclined plane expansion ring. The clamp is advantageous in improving the rigidity of webs, ensuring the machining quality of the webs, reducing the technical requirements on workers, improving the machining efficiency, and reducing the workers' labor intensity. The clamp can be applied to the machining of other turbomachine webs only by replacing a height adjusting gasket and an expansion slide block.
Description
Technical field
The utility model relates to turbine web anchor clamps.
Background technology
Along with the extensive use of blisk on aero-engine, following high thrust-weight ratio, bypass ratio engine make Blisk more complicated, the excellent application on blisk such as material, the blisk manufacturing technology has been proposed higher challenge, China drops into a large amount of human and material resources the blisk manufacturing technology is studied, seek low cost, low pollution, high efficiency, high-quality composite manufacturing, to satisfy aero-engine to the demand of blisk.
Because the blisk material is high temperature alloy and titanium alloy, it all is difficult-to-machine material, especially when turning blisk web, web occurring especially should not process, easily distortion, be difficult to guarantee machining accuracy, technical ability requirement to the operator is very high, is to rely on the processing experience to be processed in turning fully, and adds man-hour at finish turning, also be the processing mode that adopts little cutting-in, working (machining) efficiency is very low.Because need to repeatedly change cutter adds the worker, has increased the processing risk.Improved workman's labour intensity.
Process at present blisk, the design of anchor clamps mainly contains the trend of three aspects,
1) adopts the supplemental support (flexible support) of floating
2) adopt adjustable fixed support
3) adopt the shape identical with the web profile as the anchor clamps of locating surface
Adopt the benefit of the supplemental support (flexible support) of floating to be, positioning phenomenon can not appear, but a very large shortcoming is arranged also, the coefficient of stiffiness that is exactly spring is certain, the result causes elastic force to be fixed, we wish good rigidly when surplus is large, the result will cause accurately machined the time, cause the web sex change to strengthen because support force is excessive, and sex change is not easy control, if the elastic force of spring is too small, does not have again the effect of location, and all be a support, support effect is not good.
Adopt adjustable fixed support, the web sex change that can avoid the pressure of spring to cause, but his shortcoming is: when adjusting the dynamics that we support, be difficult to allow all strong points stressed evenly, and inevitably have the upwards trend of jack-up part, produced and crossed the location.Along with the removal of surplus, inhomogeneous power can make web produce sex change, and this sex change just is introduced in the mismachining tolerance of parts all, even if use the method for playing table to support adjustment, but when locking support force is changed.Like this, reduced the machining accuracy of part, and all be a support, support effect is not good.
The benefit that adopts such anchor clamps is not introduce the part deformation that external force causes, improves the machining accuracy of part, and shortcoming is: after the rough turning processing, heat-treat, cause the web distortion.Actual parts can not and the completely gapless applying of locating surface of anchor clamps.So just the gap between part and the anchor clamps locating surface is incorporated in the mismachining tolerance.Reduced the machining accuracy of web.
By the analysis to above three kinds of typical anchor clamps, draw: above three kinds of anchor clamps are in order to guarantee the machining accuracy of web, when the restriction vertical direction moves, all adopted the support (supplemental support/fixed support) of vertical direction, part just has been subject to the impact of external force on vertical moving direction like this, has affected on the contrary the machining accuracy of part.
Summary of the invention
The purpose of this utility model is to provide a kind of turbine web anchor clamps without the vertical direction support.
The utility model provides a kind of turbine web anchor clamps, mainly comprise base, pillar, upper disk, locating ring and pressure hook, upper disk is fixed on the base by pillar, locating ring and pressure hook are fixed on the disk, pressure hook is determined its hook direction with pin, it is characterized in that: be fixed with the expansion chuck body on the axis of upper disk, the inclined-plane cinch bolt is housed on the expansion chuck body, cover has the inclined-plane distensible ring on the inclined-plane cinch bolt, there is gland cinch bolt upper end, inclined-plane, gland is fixed on the expansion chuck body, the inclined-plane cinch bolt is regulated its upper-lower position with nut, between gland and expansion chuck body positioning sliding block is housed, the inner of positioning sliding block is close on the inclined-plane distensible ring.
During use, use first the centering band of clamp base that anchor clamps are carried out centering, then according to the requirement of part drawing part is carried out centering, use the pressure hook compressing component, the size of positioning sliding block during afterwards according to jig Design, hole in the web is carried out rough turn, make in the web hole dimension near expansion positioning body size.Then the expansion anchor clamps are put into anchor clamps.Use suitable power, screw the nut of inclined-plane cinch bolt with spanner, make hole in the positioning sliding block swelling web.
The turbine web anchor clamps that the utility model provides, its expansion chuck body can be fixed on the upper disk with screw rod and nut, in order to up load and unload the expansion anchor clamps on the disk.
The turbine web anchor clamps that the utility model provides, its pressure hook afterbody can have screw thread, is fixed on the upper disk with nut, in order to regulate the thickness that the spacing of pressure hook and locating ring is adapted to turbine web centring ring.
The turbine web anchor clamps that the utility model provides can have the adjustment packing ring between its expansion chuck body and the upper disk, so that the height of guide runner is consistent with hole in the web.
The turbine web anchor clamps that the utility model provides, its advantage is: the overall stiffness that well improves web, and be without crossing the auxiliary rigid support in location, the solution of this anchor clamps success the errors introduced because of support force of other rigid support, affect the problem of machining accuracy.Use these anchor clamps can guarantee the requirement on machining accuracy of part, guarantee the blisk crudy, reduce the specification requirement to the workman, improve working (machining) efficiency, reduce the cost labor strength, reduce the processing risk.And this anchor clamps machining accuracy is not high, and processing cost is moderate.These anchor clamps adopt modularized design, as long as change Height Adjustment packing ring and two parts of positioning sliding block, just can be applied in the processing of other turbine webs.Saved cost, shortened the manufacturing cycle of anchor clamps, can sound assurance the timely payment of part.
