Abstract
The utility model discloses a hollow blade correction tool, which comprises a support frame and a power device. The support frame is formed by a support, and a seat and a cross beam which are arranged on the support in parallel. The power device is mainly formed by an electric pump and a hydraulic cylinder. The cross beam is provided with a through slot perpendicular to ground, the hydraulic cylinder is movably mounted inside the through slot of the cross beam, the seat is arranged below the cross beam, and a molded line block matching with a molded line of a corrected hollow blade is arranged on the seat. The hollow blade correction tool corrects deformation of a hollow blade and minimizes the deformation, thereby guaranteeing smooth fine machining on the hollow blade of a next procedure. The hollow blade correction tool has the advantages of high correction precision, high product quality and short production cycle.
Description
Technical field:
The utility model is a kind of rectification frock of hollow blade, and is main with the rectification of doing the lagging edge distortion of nuclear power hollow blade welding back.
Background technology:
Hollow blade is in process, and the lagging edge distortion after the phenomenon that easily deforms after welding, the especially welding of nuclear power hollow blade is more outstanding.There is not a kind of Special Equipment to correct at present with the hollow blade of the distortion of opposing, when being corrected, the hollow blade of distortion to spend the plenty of time, work difficulty is very big, and deflection can not be effectively reduced, influence the fine finishining that subsequent processing carries out hollow blade, so just had a strong impact on the quality of production and the production cycle of hollow blade.
Summary of the invention:
The purpose of this utility model is in order to improve the quality of hollow blade, to shorten the process-cycle, a kind of rectification frock that can overcome the special-purpose hollow blade of above-mentioned prior art deficiency being provided.
The utility model is realized by the following technical solutions:
A kind of rectification frock of hollow blade, comprise bracing frame and power set, support frame as described above is made of base that is parallel to each other on support, the support and crossbeam, described power set mainly are made of electrodynamic pump and hydraulic jack, described crossbeam has groove perpendicular to the ground, the hydraulic jack activity is assemblied in the groove of crossbeam, and base is located at the below of crossbeam, is provided with on base and the suitable molded lines cushion block of molded lines of being corrected hollow blade.
Has the groove that the molded lines cross section on hollow blade and the molded lines cushion block aligns on the described molded lines cushion block.
Described hydraulic jack is assemblied on the crossbeam by roller and securing member activity.
The electrodynamic pump of described power set is arranged on the power set support on the bracing frame.
Groove on the described crossbeam is provided with along crossbeam length.
The beneficial effects of the utility model are:
Adopt above-mentioned frock that the distortion of hollow blade is corrected, it is minimum that deflection is dropped to, and guaranteed that subsequent processing carries out smoothly to the fine finishining that hollow blade carries out, and has precision height, product quality height, the characteristics with short production cycle of correcting.
Description of drawings:
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the support frame structure schematic diagram in the parts of the present utility model.
Code name implication among the figure:
The 1-base; The 2-support; The 3-electrodynamic pump; The 4-hydraulic jack; The 5-crossbeam; 6-molded lines cushion block; 7-power set support; The 8-roller; The 9-securing member.
The specific embodiment:
Referring to Fig. 1～Fig. 3: the utility model comprises bracing frame and power set, and bracing frame is made of base 1 that is parallel to each other on support 2, the support 2 and crossbeam 5, and crossbeam 5 has groove perpendicular to the ground, and this groove is provided with along crossbeam length.The support 2 of crossbeam 5 one ends and this end is provided with power set support 7, and bracing frame mainly is to be welded by various channel-section steels and gusset, and is simple in structure.Power set are made of electrodynamic pump 3, hydraulic jack 4, Pressure gauge and gauge stand, hydraulic jack 4 is assemblied in the groove of crossbeam 5 by roller 8 and securing member 9, crossbeam 5 is blocked, hydraulic jack 4 under the effect of electrodynamic pump 3 can be on crossbeam 5 move left and right, the assembling mode of hydraulic jack on crossbeam is various, for example, can also be that the hydraulic jack upper and lower all is a roller etc., no matter how fixing, just passable as long as hydraulic jack slides in can the groove on crossbeam.Electrodynamic pump 3 is arranged on the power set support 7 on the bracing frame.Base 1 is located at the below of crossbeam 5, is provided with on base 1 and the suitable molded lines cushion block 6 of molded lines of being corrected hollow blade, has the groove that the molded lines cross section on hollow blade and the molded lines cushion block aligns on this molded lines cushion block 6.
The utility model is work like this:
With the hollow blade behind the welding deformation be placed on the suitable molded lines cushion block 6 of its molded lines on, according to molded lines cross section and the alignment of the molded lines cross section on the molded lines cushion block 6 of the position of groove on the molded lines cushion block 6, then hollow blade is fixed simultaneously hollow blade.Then start the electrodynamic pump 3 of power set, at hydraulic jack 4 under the effect of electrodynamic pump 3 in move left and right on the crossbeam 5 (hydraulic jack 4 also can be manually moves on crossbeam 5), the hollow blade deformation place that centering need be corrected, hydraulic jack 4 stretches to the deformation place of hollow blade, press to this position, vane type line cross section to distortion is carried out orthopedic one by one, the deformation place of hollow blade is corrected like this, it is minimum that the deflection of hollow blade deformation place is dropped to, and guarantees that subsequent processing carries out smoothly to the fine finishining that hollow blade carries out.
