Abstract
The utility model provides a rotating tray used in the stamping working procedure for a stator punching sheet for purpose of eliminating the cumulative stacking height error of stators due to the thickness error of a silicon steel sheet. The rotating tray comprises a base plate and a cover plate, wherein the cover plate can rotate around a fixed axis relative to the base plate. When the rotating tray is in use, the single-piece materials to be blanked or the blanking pieces for mark slots to be stamped and positioning key slots to be stamped are placed on the rotating tray by stacking, and when 60 to 80 pieces are stamped, the rotating tray rotates for 90 degrees during the blanking process or during the process of stamping the mark slots and the positioning key slots; and the rotating tray rotates for 90 degrees, and the thicker (or thinner) position with different heights of the single-piece material or the blanking pieces rotates in the stacking height direction, so that the cumulative stacking height error of the stator iron core for the silicon steel sheet can be eliminated during the installation of the stator iron core.
Description
Technical field
The utility model relates to a kind of simple frock that the silicon steel sheet stator core laminates the accumulation difference in height that is used to eliminate, and specifically, is a kind of rotary-tray that is applied in the punch process operation of stator punching.
Background technology
Local higher or local phenomenon on the low side always appears in the punching of electric machine stator iron full circle type when laminating, along with the increase of every electric machine stator iron silicon steel sheet quantity, this kind phenomenon can be obvious further.As when using the thick stator punching of 0.5mm to laminate 1100, local height difference even can reach more than the 4mm has seriously exceeded the design allowed band of stator core sometimes.Tracing it to its cause, is because the excessive phenomenon of local burr has appearred in stator punching when punch process on the one hand; Then be on the other hand since silicon steel coiled material itself intrinsic thickness accumulation of error generation.The utility model mainly is the solution at the latter.
The electrician in the operation of rolling, always can occur middle phenomenon of sparing with the both sides became uneven with the silicon steel coiled material.According to national standard, the electrician with the silicon steel coiled material in 1 meter width range, the thickness error be not more than 0.02mm be qualified.Field practice is found, the phenomenon that silicon steel coiled material ubiquity thick middle both sides are thin, and the silicon steel coiled material 1 of expansion as shown in Figure 1, in general part (being two parts between the dotted line among the figure) 11 is always thicker than its edge parts at both sides 12 therebetween.The coiled material thickness error that Different Silicon coil of strip material producer is provided also has nothing in common with each other.
The punch process operation of making full circle type stator punching with the silicon steel coiled material is generally (referring to Fig. 2):
1, cuts material, silicon steel coiled material (coiled strip) 1 along the line 3 is cut into monolithic material 2;
2, to monolithic material 2 blankings, promptly fall cylindrical 21 and centre bore 22 (as shown in Figure 2) obtain the blanking sheet;
3, to the blanking sheet towards outer marker groove and positioning spline;
4, jet-bedding separates.
Initial under the situation of no relevant tool, mainly adopt the nature transposition, promptly the blanking sheet is placed at random when blanking, so also can eliminate the thickness error of part.But the raising that requires along with the quality of production, Huan Wei no thoroughness has become gradually to influence stator core with unsteadiness and has laminated accuracy factors naturally.
Summary of the invention
The purpose of this utility model provides a kind of punch process operation that is used for stator punching, laminates the rotary-tray of accumulation height error with effective elimination because of silicon steel sheet self thickness error causes stator.
A kind of being used to eliminated the rotary-tray that the silicon steel sheet stator core laminates the accumulation difference in height, comprises base plate, cover plate, and described cover plate can rotate around a fixed axis with respect to base plate.
During use, will treat the monolithic material of blanking or treat that the blanking sheet windrow of stamp mark groove and positioning spline is placed on the rotary-tray that 60 to 80 of every stamping-outs revolve rotary-tray to turn 90 degrees and get final product when carrying out blanking or stamp mark groove and positioning spline.Owing to revolve and turn 90 degrees, make the place of thicker (perhaps thinner) different-thickness of monolithic material or blanking sheet rotate along with the short transverse of stacking, when being mounted to stator core like this, can eliminating the silicon steel sheet stator core and laminate the accumulation difference in height.Therefore the beneficial effects of the utility model are: can effectively eliminate because of silicon steel sheet and laminate the accumulation height error because of the stator that self thickness error causes.
For above-mentioned rotary-tray, in order to make base plate and cover plate coaxial rotation flexible, on the opposite face of base plate and cover plate, respectively have a relative annular groove, the cross section of annular groove is V-shaped; A plurality of balls are arranged in the relative annular groove; Cover plate rotates with respect to base plate by the described ball that can roll in relative annular groove.
For above-mentioned rotary-tray, have the location hole coaxial on the cover plate with described fixed axis, to pass location hole with the coaxial locating shaft of described fixed axis and be fixed on the base plate, the top of locating shaft is lower than the upper surface of cover plate; Gapped between location hole and the locating shaft.Locating shaft has and prevents from effectively to break away from base plate when cover plate from rotating, and has guaranteed that cover plate rotates around fixed axis all the time.
For above-mentioned rotary-tray, the cross section of annular groove is 120 ° V-arrangement, and the case hardness of V-ring groove and ball all is not less than 45～48HRC.
