Description
Technical field
The present invention relates to motor stator upset frock, be specially large-size stator 180 degree upset clamping devices.
Background technology
Large-size stator (about 25 tons of weight, diameter 4800mm) therefore can't carry out clamping in outer radius owing to assembling coil at the external diameter slotted vane, can only stop portion be installed at stator and carry out clamping.
Prior art is to penetrate a mandrel at the seam position of stator when carrying out the upset of large-size stator 180 degree, utilizes stator inner hole seam end face screw to be connected with a plurality of bolts on the mandrel; End with mandrel is the center, lifts by crane with overhead traveling crane, utilizes moving of overhead traveling crane after the lifting; Realize 90 ° upset earlier; And then be the center with the other end of mandrel, utilize the overhead traveling crane lifting to move once more, thereby realize that 180 ° of stator stand up.This flipped form labour intensity is high, and efficient is low, needs the frequent assembling-disassembling bolt of operating personnel, overturns about a time spent 2h; Poor stability in switching process, needs the meticulous cooperation of operative employee and overhead traveling crane.
Adopt two column machines of standing up to realize that stator overturns safely and efficiently; But, in switching process, produce following problem: one, in turning over the process of turnback, have the fit-up gap between the positioning disc because of stator seam endoporus and tipper owing to lacking and standing up the supporting clamping device of machine; Be turned to 90 when spending; The effect of stator dead weight produces positioning disc to be impacted, and will produce damage to stator seam endoporus, positioning disc, can cause damage to the machine of standing up when serious; Two, how to guarantee that stator has reliable mechanical to clamp, and can not cause the stator landing after turning over turnback; The 3rd, how clamping before and after upset and dismounting realize fast automatic.In order to address the above problem, designed this cover upset clamping device.
Summary of the invention
The present invention is present owing to lacking and standing up the supporting clamping device of machine in order to solve, and adopting pair column machines of standing up to carry out the problem that exists when large-size stator 180 overturns, provides a kind of large-size stator 180 to spend the upset clamping devices.
The present invention adopts following technical scheme to realize: large-size stator 180 degree upset clamping devices, comprise base for supporting, and the last supporting surface of base for supporting is fixed with at least four hydraulic cylinders, and the expansion link end of hydraulic cylinder is fixed with briquetting; Comprise that also the upper surface is the annulus of inner conical surface, briquetting is the male cone (strobilus masculinus) that cooperates with the inner conical surface of annulus with the contact-making surface of annulus upper surface.During use, the workbench of base for supporting and tipper fixes, and large-size stator is hung on clamping device; Make the seam of large-size stator be supported in the last supporting surface of base for supporting; With the upper surface is that the annulus of inner conical surface places on the seam of large-size stator, cooperating between the Driven by Hydraulic Cylinder briquetting, the inner conical surface through annulus and the male cone (strobilus masculinus) of briquetting; Annulus is compressed, thus the clamping of realization large-size stator.
Further, supporting surface is fixed with positioning disc on base for supporting, and hydraulic cylinder is fixed on the positioning disc; The briquetting bottom is provided with T shape slide block, has the T shape chute (the T shape slide block that is the briquetting bottom is embedded in the T shape chute on the positioning disc) that cooperates with the T shape slide block of briquetting bottom on the positioning disc, like this; Not only can realize guiding to briquetting; More crucial is large-size stator is after turning over turnback, and T shape slide block is just hung in T shape chute, guarantees that more large-size stator does not drop; Further, the anchor ring of positioning disc is the conical surface (upper diameter is little, lower diameter is big), the guiding when being used for the large-size stator lifting, the i.e. installation of the seam of more convenient large-size stator supporting surface on base for supporting.
Large-size stator 180 degree upset clamping devices of the present invention are corollary apparatus of tipper; Can fully clamp large-size stator; Avoided large-size stator in switching process, to have the damage that the mobile impact that produces produces stator seam endoporus, tipper and after turning over turnback, do not dropped because of the large-size stator Heavy Weight because of the gap; Solved the technical barrier that large-size stator stands up; Improved production efficiency and the fail safe of standing up process, but standing up of Rapid Realization large-size stator batch raised the efficiency 8 times.Simultaneously, guaranteed that stator has reliable mechanical to clamp, and can not cause the stator landing after turning over turnback; Can also be fast automatic clamping and dismounting before and after the realization upset.
