Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the disc type gear gear shaving technology equipment in embodiment is mainly made up of mandrel 1, outer cone elastic expansion-sleeve 2, the first straight pin 3, the second straight pin 4, inner cone elastic expansion-sleeve 5, disk spring group 6, pressing plate 8 and center sleeve 9.
As shown in Figure 1, described mandrel 1 center, left side is provided with centre bore 1a, limited location platform 1b, tensioner section 1c and hold-down segment 1d on mandrel 1, the tensioner section 1c that described outer cone elastic expansion-sleeve 2 is sleeved on mandrel 1 above also can move axially, described inner cone elastic expansion-sleeve 5 is sleeved on outer cone elastic expansion-sleeve 2, and the male cone (strobilus masculinus) of outer cone elastic expansion-sleeve 2 matches with the inner conical surface of inner cone elastic expansion-sleeve 5; Described the first straight pin 3 and the second straight pin 4 are radially fixed on mandrel 1, and outer cone elastic expansion-sleeve 2 and inner cone elastic expansion-sleeve 5 are respectively processed with many places breach at circumferencial direction, and the first straight pin 3 and the second straight pin 4 are embedded in breach; Described disk spring group 6, pressing plate 8 and center sleeve 9 are sleeved on the hold-down segment 1d of mandrel 1 successively, outer cone elastic expansion-sleeve 2 end faces are pressed on disk spring group 6 tops, one end, disk spring group 6 other ends withstand on pressing plate 8, pressing plate 8 compresses by the center sleeve 9 being sleeved on mandrel 1, center sleeve 9, center sleeve 9 centers, right side are provided with center hole 9a, and the centre bore 1a on this center hole 9a and mandrel 1 left side is positioned on same axis.
As shown in Figure 1, in the utility model embodiment, the breach interlaced arrangement in a circumferential direction on breach and inner cone elastic expansion-sleeve 5 on described outer cone elastic expansion-sleeve 2 is even to guarantee outer cone elastic expansion-sleeve 2 and inner cone elastic expansion-sleeve 5 harmomegathus amount when the tensioner.Preferably, the breach on described outer cone elastic expansion-sleeve 2 and inner cone elastic expansion-sleeve 5 is U-shaped breach.
As shown in Figure 1, described the first straight pin 3 is that outer cone elastic expansion-sleeve 2 comes off from mandrel 11 when preventing from taking out workpiece gear 7, described the second straight pin 4 is too much motions to the inside of inner cone elastic expansion-sleeve 5 when preventing tensioner, and the first straight pin 3 and the second straight pin 4 positioning workpieces gear 7 more reliably, facilitate the handling action of workpiece gear 7, greatly improved the simplicity of operation.
As shown in Figure 1, have six disk springs in described disk spring group 6, they are pressed diagramatic way and arrange.The medial surface of described pressing plate 8 is provided with cavity 8a, and described disk spring group 6 one end are placed in this cavity 8a.
Operation principle of the present utility model is as follows:
When concrete application, the centre bore 1a on the center hole 9a on center sleeve 9 right sides and mandrel 1 left side is top fixing with lathe two ends respectively.When starting after the top hydraulic pressure of tailstock tool, tailstock centre hydraulic, promotes center sleeve 9 and pressing plate 8, and pressing plate 8 shrinks disk spring group 6.In the time arriving corresponding pressure, pressing plate 8 contacts with the end face of workpiece gear 7.Under the effect of tailstock centre pressure, disk spring group 6 acts on inner cone elastic expansion-sleeve 5, inner cone elastic expansion-sleeve 5 is inwardly moved, under the effect of interior male cone (strobilus masculinus), make also spreading slowly of outer cone elastic expansion-sleeve 2, until tensioner workpiece gear 7 endoporus centering, now tailstock centre pressure is dispersed to pressing plate 8, make it also to complete reliable location with the end face of workpiece gear 7, both completed the centering of workpiece gear 7, also completed the end face positioning compression of workpiece gear 7.
When after workpiece gear 7 completion of processing, close the top hydraulic pressure of tailstock tool, the top pressure of tailstock tool disappears, and under the elastic force effect of disk spring group 6, pressing plate 8 unclamps and separates with workpiece gear 7 end faces.Shrink respectively at outer cone elastic expansion-sleeve 2 and inner cone elastic expansion-sleeve 5, leave the endoporus of workpiece gear 7, now can conveniently take out workpiece gear 7.
