The invention discloses a magnet yoke assembling positioning guider and a magnet yoke assembling method. During assembling, the magnet yoke assembling positioning guider is placed between two adjacent layers of magnet yokes. The magnet yoke assembling positioning guider comprises V-shaped projections (1) and V-shaped recessed blocks (2), wherein the V-shaped projections (1) and the V-shaped recessed blocks (2) cooperate with each other and are connected through connecting pieces (3). After accurate positions are found, the V-shaped blocks (1) and the V-shaped recessed blocks (2) are respectively welded firmly to two adjacent layers of magnet yoke points; after the connecting pieces (3) are cut off, the two adjacent magnet yokes are then disconnected, spot welding positions are consolidated, and the magnet yoke assembling positioning guider is installed in such a way; and during installation, magnet yokes, welded with the V-shaped blocks (1) and the V-shaped recessed blocks (2), in the two adjacent layers of magnet yokes are piled up, and small ends of bosses of the V-shaped blocks (1) are enabled to be inserted into large ends of grooves of the V-shaped recessed blocks (2), such that guiding and positioning are automatically carried out.
Description
Technical field
The present invention relates to technical field of hydraulic generators, especially relate to a kind of multilayer yoke assembling and positioning guider and multilayer yoke assembly method.
Background technology
Hydraulic turbine generator magnet yoke is the key components and parts of unit, is usually connected with generator shaft in the mode of hot jacket, and main shaft and yoke are that interference fit is connected.Yoke outer ring is polygonized structure, and each planar design has T-shaped or dovetail slot, and excitation winding magnetic pole is fixed in each plane by taper key.By the needs that hydraulic generator model and electromagnetism calculate, thickness and the diameter excursion of yoke are very large.When thickness and diameter exceed casting and manufacturing limit or have aeration structure to need, yoke layering will be considered.Now that the course of processing or hot jacket assembling process each layering yoke all need accurate overlapping location can ensure the form and position tolerance of each plane of yoke polygon and each T-slot, dovetail slot.Otherwise cannot taper key accurate fixed excitation winding magnetic pole be passed through.Particularly when hot jacket yoke, each layering yoke tapping temperature is 300 ~ 350 degree, and personnel are difficult near operation, and as operate miss does not complete accurate location within the time limited, yoke also can be caused to extract, and economic loss is serious.Be all in the past by position limitation method or repeatedly adjusting method meet design requirement, but form and position tolerance is difficult to accurately to ensure, efficiency is extremely low, and separately after cannot accurate recovery.
Summary of the invention
In order to overcome the defect of prior art, the invention provides a kind of yoke process and assemble locating guide device and yoke assembly method, being difficult to ensure with upper magnet yoke form and position tolerance in assembling and hot jacket process to solve prior art two layers, the technical problem that efficiency is extremely low.
In order to solve the problems of the technologies described above, on the one hand, the invention provides a kind of yoke assembling and positioning guider, it comprises, and to have cross section be trapezoidal or the V-type projection of triangle boss; Having cross section is recessed piece of V-type that is trapezoidal or triangular groove; Described V-type projection and recessed piece of V-type cooperatively interact, and are connected between them by connector.
As optimal technical scheme, yoke assembling and positioning guider provided by the invention, described connector is sunk screw.
As further improvement opportunity scheme, yoke assembling and positioning guider provided by the invention, after described V-type projection and recessed piece of V-type are connected, has the gap for being convenient to cut off described connector between described V-type projection and V-type recessed piece of two opposite faces.
In order to solve the problems of the technologies described above, on the other hand, the invention provides a kind of yoke assembly method, comprise the following steps:
At least two group yoke assembling and positioning guiders are placed between adjacent two layers yoke respectively; Described yoke assembling and positioning guider comprises that to have cross section be trapezoidal or the V-type projection of triangle boss; Having cross section is recessed piece of V-type that is trapezoidal or triangular groove; Described V-type projection and recessed piece of V-type cooperatively interact, and are connected between them by connector; The yoke of adjacent two layers requires that reference circle is consistent, positional symmetry;
After capturing position, by described V-type projection and recessed piece of V-type firm with the yoke spot welding of adjacent two layers respectively;
After connector is cut off, then adjacent two layers yoke is taken apart, consolidate spot welding position, complete the installation of yoke assembling and positioning guider;
Being stacked together being welded with V-type projection in adjacent two layers yoke with the yoke being welded with recessed piece of V-type again during installation, making the microcephaly of the boss of V-type projection insert in the major part of the groove of recessed piece of V-type, automatically carrying out leading and locating.
Technical scheme provided by the invention, by using yoke assembling and positioning guider, after the microcephaly of the boss of V-type projection being inserted the major part of the groove of recessed piece of V-type, achieves automatic guide and location, efficient quick dexterously, precisely errorless.After taking apart can fast, accurate recovery, ensure the morpheme meter of layering yoke.In the assembling of multilayer yoke, significantly can increase work efficiency in hot jacket process, avoid the overproof and economic loss of the product that causes because of misoperation.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and form a application's part, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
