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 center hole of the two ends of main shaft 6, be all provided with one and insert stifled 1, at main shaft 6 circumference, 4, four fanning strip 4 outer round surface of four fanning strips are installed and are provided with at least twice clip 5; In main shaft 6 pyramid shaft shoulder sides (right side of Fig. 1) having closed 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, between this frock backing plate 10 and positioning body 7 inner faces, be provided with backing plate 8, 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 faces are provided with arm-tie 13, between arm-tie 13 and backing plate 8, by long bolt 11, are connected, and realization is strained and fixed.
As shown in Figure 3, in order to pass through the pyramid of main shaft 6 left ends, backing plate 8 is two halves dissection type symmetrical structure, between two halves part split surface, leaves 10 ± 1mm gap, and backing plate 8 is provided with a circle screwed hole (embodiment is 6) along circumference inner ring, for being connected with arm-tie 13; Backing plate 8 is provided with a circle screwed hole (embodiment is 4 groups, 4 every group) in addition along circumference outer ring, for being connected with frock backing plate 10 and fanning strip 4, these backing plate 8 halves required thicknesses, with processing, guarantee consistency of thickness, and depth of parallelism franchise 0.03mm.
As shown in Figure 4, positioning body 7 is set to two halves part dissection type symmetrical structure, two halves part positioning body 7 is connected and fixed by bolt 3 12 correspondences along between the ear seat at diameter two ends, deciliter face that two halves part positioning body is 7 leaves 2 ± 0.2mm gap, guarantee handle and rear and main shaft 6 firm positions, can bear clamping force and cutting force after group circle, the thickness of positioning body 7 both ends of the surface leaves allowance, and rear processing both ends of the surface thickness, must guarantee that size L(is the installing space length of fanning strip 4), with reference to Fig. 1 and Fig. 8, size L presses formula below and calculates:
L=L1-L2+H，
Wherein: L1 is the length of fanning strip 4, L2 be fanning strip 4 left sides apart from the distance of main shaft 6 pyramid left sides, H is the thickness of backing plate 8,
As shown in Figure 5, a plurality of and the unthreaded hole (embodiment is 6) that is uniformly distributed along the circumference on arm-tie 13, in use with backing plate 8 by long bolt 11 carry out handle with.
As shown in Figure 6, on axle end baffle plate 2, be uniformly distributed along the circumference four groups of handles and unthreaded hole (embodiment is four groups, every group each 2), in use with fanning strip 4 by bolt 1 carry out handle with.
As shown in Figure 7, radially uniform a plurality of screwed holes on clip 5 (4 of embodiment), and correspondence disposes many jackscrews (4 of embodiment), in use by four fanning strips, 4 clampings, prevents that in process, fanning strip 4 is loosening.
The assembling main points of above-mentioned dissection type backing plate positioner are:
As shown in Fig. 1, Fig. 8, positioning body 7 is closed to when location at the outer bundle of circles of main shaft 6, size L(in survey map 8 is for determining fanning strip and main shaft relative axial position), ensure 0.3～0.8mm allowance, with handle, close bolt 3 12 tight two halves part positioning bodies 7, guarantee positioning body 7 both ends of the surface alignment, upper lathe processing positioning body 7 both ends of the surface, press ± 0.2mm of size L controls, and guarantee that positioning body 7 both ends of the surface are vertical with main shaft 6 axis, 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, by backing plate 8 and arm-tie 13 during respectively with positioning body 7 both ends of the surface location, 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(inspection 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, with flat board, recheck, require this end face flatness to be not more than 0.05mm, after meeting the demands, can be connected by long bolt 11.
As shown in Figure 1, before 8, fanning strip 4 and backing plate close, with two clips, 5 adapted jackscrews, four fanning strips 4 are clamped respectively, due to inclined-plane component effect, frock backing plate 10 end faces (coplanar with fanning strip 4 end faces) are sturdy with backing plate 8 locating surfaces, at 29, bolt and front, with clearance gauge, detect, composition surface periphery 0.05mm clearance gauge does not enter, can with, prevent distortion.
As shown in Figure 1, in order to prevent that fanning strip 4 from producing distortion, clip 5 must be positioned at main shaft 6 and fanning strip 4 contact-making surface places, inclined-plane, and in process, clip 5 must not unclamp, and during play clip 5, can not unclamp two clips 5, one by one plaies simultaneously simultaneously.
The present invention utilizes the method for dissection type backing plate processing fanning strip cylindrical, according to following steps, implements:
First, on main shaft 6, handle closes positioning body 7, 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, processing positioning body 7 both ends of the surface, and press ± 0.2mm of size L controls, and guarantee that positioning body 7 both ends of the surface are vertical with main shaft 6 axis, franchise is not more than 0.02mm, guarantees that positioning body 7 both ends of the surface are parallel to each other, and franchise is not more than 0.02mm;
Secondly, on main shaft 6, pack four fanning strips 4 into, with two groups of clips, 5 adapted jackscrews, clamp respectively four fanning strips 4, backing plate 8 is fixed by frock backing plate 10 and fanning strip 4 stub ends, and held connecting axle end-stopping plate 2 fanning strip 4 microcephalies; Use long bolt 11 that arm-tie 13 is connected with backing plate 8 and wouldn't with leveling ruler, check that backing plate 8 end face flatnesses are not more than 0.05mm tightly, recheck backing plate 8 both ends of the surface and fanning strip 4 and positioning body 7 end clearances, be all not more than 0.05mm;
Finally, tight long bolt 11, carry out the Excircle machining of fanning strip 4.
The inventive method is simple, and apparatus structure used is simple, and the problem that axially cannot locate while having solved fanning strip Excircle machining, has reduced difficulty of processing, has improved crudy, has reduced manufacturing cost simultaneously.
