The specific embodiment
In Fig. 1, a kind of drilling tool mold of motor bed-plate end-face hole comprises a bushing plate 1.This bushing plate 1 adopts carbon structural steel.
For the weight that reduces mold with make things convenient for picking and placeing of mold, as shown in Figure 1 and Figure 2, have a technology cavity 2 that connects at its axis of bushing plate 1 upper edge.
Press the setting of support model and position, lug limit,, drill bushing 3 is arranged, guiding drill bit during in order to boring in this bushing plate 1 tight fit according to the boring exact position of support end-face hole.The present invention selects 4 drill bushings for use according to the support model that will process, and promptly drill bushing 301,302,303,304, and drill bushing all adopts the T10A Quenching Treatment, in case serious wear between drill bit and drill bushing, increases the service life of mold.
In Fig. 2, on the circumferential end surfaces of bushing plate 1 one sides, have the mold seam 4 that matches with the electric machine stand seam.
In Fig. 1, Fig. 2, on the bushing plate 1 of corresponding mold seam 4 opposite sides, be symmetrically fixed with two bearings 501,502, between the bearing hole of two bearings 501,502, be equipped with rotating locating rack 6, the a positioning block 7 that is fixedly connected on the positioning end of this locating rack 6, this locating piece 7 contact with the support footing realizes circumferentially location.
As shown in Figure 1, locating rack 6 by be assemblied between two bearing holes turning cylinder 601 and on this turning cylinder two backstays 602,603 of being fixedly connected of symmetry form, locating piece 7 is fixedly connected on the positioning end of two backstays 602,603.The line of centres of two drill bushings 303,304 on the locating surface 701 of locating piece 7 and the bushing plate 1 is parallel.If when fixing welding, cause the position of locating piece 7 to be subjected to displacement and can't guarantee the depth of parallelism, can on abrasive machine, carry out reconditioning, until with till the line of centres of two drill bushings 303,304 on the bushing plate 1 is parallel to locating surface 701.
In Fig. 1, Fig. 2, on locating rack 6, be provided with the torsionspring 8 that the locating piece 7 that can make on the locating rack produces thrust.
As shown in Figure 1, torsionspring 8 is two, and promptly torsionspring 801,802, and the rotation direction of torsionspring 801,802 is opposite, and it is corresponding respectively to be sleeved on the turning cylinder 601 of 502 of backstay 602 and bearing 501 and backstay 603 and bearings.Two working ends of torsionspring 801 can act on respectively on bearing 501 and the backstay 602, also can act on bushing plate 1 and the backstay 602; Two working ends of torsionspring 802 are can act on respectively on bearing 502 and the backstay 603 equally, also can act on bushing plate 1 and the backstay 603.
The present invention is in order further to avoid center and lug deflection after support shaft extension end is holed too big, correspondence is processed with technology gap 901,902 respectively on the bushing plate 1 of drill bushing 301 both sides, to form a pre-determined bit boss 10 on bushing plate 1, the profile of this pre-determined bit boss 10 is consistent with support lug appearance profile.After laying mold, before the boring, can with the naked eye observe the profile and the support lug appearance profile deviation size of the pre-determined bit boss 10 of technology gap formation.Be exactly to bore not flanged and during in another effect of the pre-determined bit boss 10 that forms owing to two technology gap 901,902 on the bushing plate 1 not with the support hole of footing, can utilize itself and support lug to position, carry out rig seat end-face hole again, enlarged the versatility of mold.
As shown in Figure 3, on the vertical down workbench 13 that is placed on radial drilling machine of support 11 behind the milling support footing and flange union end, the present invention is placed on the support seam, pull-up locating rack 6 puts down again, elastic force by torsionspring 8, locating piece 7 is compressed on the plane that is attached to support footing 12, but whether the pre-determined bit boss profile and the support lug appearance profile of the formation of the technology gap on the perusal bushing plate at this moment be unanimous between the higher and lower levels, with position and the lug deflection after further preventing to hole, start drilling machine then, drill bit 14 guides so that the support end face is holed through drill bushing 3.
Special feature of the present invention is to have used two torsionsprings, because same specification can not be considered in the effect of spring Support because the problem that the high tolerance in center is big or the non-standard center of same specification motor height brings, no matter the support center is partially high The difference size, torsionspring all can tightly be pressed in the locating piece on the locating rack on the foot plane. Like this with the support after the milling No matter footing location has all guaranteed the position degree of support end-face hole and support foot plane in theoretical or the practice. The present invention has reasonable in design, and cost is low, and is easy to use, and the advantage of accurate positioning can increase substantially production efficiency, Reduce production costs, the machining accuracy height of workpiece, interchangeability is good.
