Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1-2, design an automatic rectify utility model frock at stator center, including, be fixed in chuck 1 on the lathe, chuck 1 upper portion is fixed with flabellum dish 3, flabellum dish 3 center department is equipped with location axle 5, location axle 5 with the main shaft of lathe is concentric.
Chuck 1 is syllogic disc structure, is equipped with slide 7 between per two sections, install in the slide 7 and be used for treating the locating piece 6 that the toper stator blank was carried out the centering, the inner circle of treating the toper stator blank cup joint in on the location axle 5, locating piece 6 is "L" shape, and its bottom is arranged in the slide 7, its upper portion height is higher than 3 upper surfaces of flabellum dish, flabellum dish 3 is including flabellum portion 4 and empty leaf portion 9, flabellum portion 4 through first bolt 8 lock in on the chuck 1, empty leaf portion 9 is located slide 7 top makes locating piece 6 is smooth slide in the slide 7, thereby it is right treat the excircle centering of processing toper stator blank.
In this utility model, the slide 7 will chuck 1 equalling divide into the three-section, flabellum dish 3 with chuck 1 is concentric, flabellum portion 4 of flabellum dish 3 will the flabellum dish 3 trisection, each 4 the size of flabellum portion is the same, first bolt 8 install in on the central line of flabellum portion 4, the central line of flabellum portion 4 with the central line coincidence of each section of chuck 1 minute dish.
Specifically, the chuck 1 is fixed on the lathe through a second bolt 2, and the second bolt 2 is installed on a center line of each section of the chuck 1.
Further, the fan blade part 4 of the fan blade disc 3 overlaps the chuck 1, and the first bolt 8 is located inside the second bolt 2.
In addition, the positioning blocks 6 comprise three groups, and the distance between each group of the positioning blocks 6 and the positioning shaft 5 is always equal. The three groups of positioning blocks 6 are completely the same in shape and size. Referring to fig. 2, here, we call the lower extreme horizontal part of locating piece 6 be collet 62, and the vertical part in upper end of locating piece 6 is clamping jaw 61, and it can be known with fig. 1, fig. 2 that this utility model's frock during operation, collet 62 is located and slides and drive clamping jaw 61 and slide in slide 7, and then makes clamping jaw 61 will wait to process the excircle centre gripping of toper stator blank.
More specifically, the diameter of the positioning shaft 5 is slightly smaller than the diameter of the inner circle of the conical guide vane blank to be processed. Because the inner chamber runner of waiting to process the toper stator blank is formed by the loam core, and is not in a die cavity with the excircle, when lower loam core, because of the influence in clearance, the interior circle and the excircle decentraction of blank can appear, but according to the production standard, the deviation in this kind of interior excircle centre of a circle is in certain within range, and this utility model discloses the diameter of well location axle 5 and the diameter deviation of waiting to process the interior circle of toper stator blank are no longer than the scope of the interior excircle centre of a circle deviation of waiting to process the toper stator blank that the production standard allows.
