Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As depicted in figs. 1 and 2, the structure of the dissection type backing plate positioner that the inventive method relies on is, comprise main shaft 6, in the two ends center hole of main shaft 6, be all provided with one insert stifled 1, at main shaft 6 circumference, four fanning strips, 4, four fanning strip 4 outer round surface are installed and are provided with at least twice clip 5; In main shaft 6 pyramid shaft shoulder side (right side of Fig. 1), conjunction there is positioning body 7, four fanning strip 4 stub ends are respectively arranged with a frock backing plate 10 in the end face groove of positioning body 7, backing plate 8 is provided with between this frock backing plate 10 and positioning body 7 inner face, backing plate 8 is fixedly connected with frock backing plate 10 and fanning strip 4 by bolt 29, and four little head ends of fanning strip 4 are fixedly connected with an axle end baffle plate 2 towards the end face (left side of Fig. 1) of the other end jointly by bolt 1; Positioning body 7 outer face is provided with arm-tie 13, is connected between arm-tie 13 with backing plate 8 by long bolt 11, realizes being strained and fixed.
As shown in Figure 3, in order to the pyramid by main shaft 6 left end, backing plate 8 is two halves dissection type symmetrical structure, leaves 10 ± 1mm gap between two half split surfaces, and backing plate 8 circumferentially inner ring is provided with a circle screwed hole (embodiment is 6), for being connected with arm-tie 13; Backing plate 8 circumferentially outer ring is provided with a circle screwed hole (embodiment is 4 groups, often organizes 4) in addition, and for being connected with frock backing plate 10 and fanning strip 4, this backing plate 8 halves required thickness, with processing, ensures consistency of thickness, and depth of parallelism franchise 0.03mm.
As shown in Figure 4, positioning body 7 is set to two half dissection type symmetrical structures, be connected and fixed by bolt 3 12 correspondence between the ear seat at two half positioning bodies 7 diametrically two ends, 2 ± 0.2mm gap is left in a deciliter face between two half positioning bodies 7, ensure handle and rear with main shaft 6 firm position, the clamping force after group circle and cutting force can be born, the thickness of positioning body 7 both ends of the surface leaves allowance, and aft-loaded airfoil both ends of the surface thickness, the installing space length of size L(and fanning strip 4 must be ensured), formulae discovery is below pressed with reference to Fig. 1 and Fig. 8, size L:
L=L1-L2+H，
Wherein: L1 is the length of fanning strip 4, L2 is the distance of fanning strip 4 left side apart from main shaft 6 pyramid left side, and H is the thickness of backing plate 8,
As shown in Figure 5, arm-tie 13 is uniformly distributed along the circumference multiple handle and unthreaded hole (embodiment is 6), in use with backing plate 8 by long bolt 11 carry out handle and.
As shown in Figure 6, axle end baffle plate 2 is uniformly distributed along the circumference four groups of handles and unthreaded hole (embodiment is four groups, often organizes each 2), in use with fanning strip 4 by bolt 1 carry out handle and.
As shown in Figure 7, radially uniform multiple screwed hole (embodiment 4) on clip 5, and correspondence is configured with more than one piece jackscrew (embodiment 4), is clamped by four fanning strips 4 in use, prevents fanning strip 4 in process from loosening.
The assembling main points of above-mentioned dissection type backing plate positioner are:
As shown in Fig. 1, Fig. 8, by positioning body 7 when the outer bundle of circles of main shaft 6 closes location, size L(in survey map 8 is used for determining fanning strip and main shaft relative axial position), ensure 0.3 ~ 0.8mm allowance, with a conjunction bolt 3 12 tight two half positioning bodies 7, ensure the alignment of positioning body 7 both ends of the surface, upper lathe locating and machining body 7 both ends of the surface, size L presses ± 0.2mm control, and ensure positioning body 7 both ends of the surface and main shaft 6 axes normal, franchise is not more than 0.02mm, and both ends of the surface are parallel to each other, and franchise is not more than 0.02mm.
According to structure shown in Fig. 1, when backing plate 8 and arm-tie 13 are located with positioning body 7 both ends of the surface respectively, end face must be adjacent to positioning body 7 both ends of the surface respectively, clearance control 0.05mm clearance gauge when being not more than 0.05mm(and checking in composition surface does not enter for suitable), backing plate 8 just becomes towards the big end surface of fanning strip 4 the length direction locating surface that fanning strip 4 adds man-hour, recheck with flat board, require that this end face plane degree is not more than 0.05mm, the rear that meets the demands is connected by long bolt 11.
As shown in Figure 1, before fanning strip 4 and backing plate 8 handle close, with two pieces clip 5 adapted jackscrew, four fanning strips 4 are clamped respectively, due to inclined-plane component effect, frock backing plate 10 end face (coplanar with fanning strip 4 end face) is sturdy with backing plate 8 locating surface, on 29, bolt with front, detect with clearance gauge, composition surface periphery 0.05mm clearance gauge does not enter, can with, prevent distortion.
As shown in Figure 1, in order to prevent fanning strip 4 from producing distortion, clip 5 must be positioned at main shaft 6 and fanning strip 4 contact of incline plane face place, and simultaneously in process, clip 5 must not unclamp, and during play clip 5, can not unclamp two pieces clip 5 simultaneously, can only play one by one.
The present invention utilizes dissection type backing plate to process the method for fanning strip cylindrical, implements according to following steps:
First, closing positioning body 7 on main shaft 6, the installing space length dimension L allowance of fanning strip 4 is 0.3 ~ 0.8mm, upper lathe inserts stifled 1 location with two ends, locating and machining body 7 both ends of the surface, and size L presses ± 0.2mm control, and ensure positioning body 7 both ends of the surface and main shaft 6 axes normal, franchise is not more than 0.02mm, and ensure that positioning body 7 both ends of the surface are parallel to each other, franchise is not more than 0.02mm;
Secondly, main shaft 6 loads four fanning strips 4, clamps four fanning strips 4 respectively with two groups of clip 5 adapted jackscrews, backing plate 8 is fixed by frock backing plate 10 and fanning strip 4 stub end, and at fanning strip 4 little head end connecting axle end-stopping plate 2; Use long bolt 11 to be connected with backing plate 8 by arm-tie 13 and tightly, wouldn't be not more than 0.05mm with leveling ruler inspection backing plate 8 end face plane degree, reinspection backing plate 8 both ends of the surface and fanning strip 4 and positioning body 7 end clearance, be all not more than 0.05mm;
Finally, tight long bolt 11, the Excircle machining of fanning strip 4 is carried out.
The inventive method is simple, and apparatus structure used is simple, and the problem axially cannot located when solving fanning strip Excircle machining, reduces difficulty of processing, improve crudy, reduce manufacturing cost simultaneously.
