The specific embodiment
A kind of lean tube radial hole tool; Central shaft hole on the tailstock 7 of lathe is equipped with tailstock mandrel 8; There is annular groove 21 in portion of tailstock core back-end; Coaxial dome platform 17 and eccentric ladder pin-and-hole 18 are arranged on the tailstock mandrel front end face, on the eccentric ladder pin-and-hole ladder pin 13 is arranged, circumferential spacing screw slot 20 is arranged on the tailstock mandrel axial plane; There is screw the below of tailstock outer face upper shaft hole; Adjusting rod 14 is housed on the screw, raised flanges dish 22 is arranged on the adjusting rod, ring flange cooperates with the annular groove 21 of portion of tailstock core back-end; Spacing screw rod screw is arranged on the tailstock side; Spacing screw rod 16 is housed on the spacing screw rod screw, locking nut 12 is arranged on the spacing screw rod, spacing screw rod inner end cooperates with spacing screw slot on the tailstock mandrel; On the dividing head 11 relative the dividing head mandrel is housed with the other end of tail stock for machine tool.
The spacing screw rod that leads in the tailstock central shaft hole is housed on the tailstock side, on the spacing screw rod locking nut is arranged, spacing screw rod inner end cooperates with spacing screw slot on the tailstock mandrel; On the dividing head relative dividing head mandrel 10 is housed with the other end of tail stock for machine tool.
Connecting rod 3 is equipped with in the adjusting rod outer end, and interlinking lever end is equipped with crank 23.Crank is made up of with spring washer 4, nut 5 long soket head cap screw 1, and crank is with rubber tube 2 outward,
Spacing handwheel 6 is equipped with in spacing screw rod outer end.
This frock is to process and design to lean pipe Fig. 1, the radial hole shown in 2.
The design of this frock is to unite completion by the tailstock after dividing head and the repacking.
2.1 the principle (seeing Fig. 3,4,5) that frock is main
To be divided into 4 little assemblings like Fig. 3,4, assembly drawing shown in 5: the assembling of (1) connecting rod assembling (2) tailstock mandrel assembling (3) tailstock assembling (4) dividing head
(1) connecting rod assembling
Form by long soket head cap screw 1, rubber tube 2,4,3 nuts 5 of 3,3 spring washers of connecting rod, adjusting rod 14, short soket head cap screw 15.Concrete assembly relation is as shown in Figure 3.This assembling mainly is to accomplish moving axially of tailstock mandrel 8, thereby reaches the axial location of lean pipe 9 and the purpose of conveniently assemble and disassemble lean pipe 9.
(2) tailstock mandrel assembling
Form (seeing Fig. 5 A-A cutaway view) by tailstock mandrel 8, ladder pin 13.The interference of ladder pin is assemblied on the tailstock mandrel 8, forms the mandrel that cooperates with lean pipe 9 eccentric orfices.
(3) tailstock assembling
Form by spacing handwheel 6, tailstock 7, tailstock mandrel 8, spacing screw rod 16, locking nut 12.Concrete assembly relation is seen Fig. 3.The key component of this assembling is seen the partial sectional view of Fig. 4 left view, and spacing handwheel 6 cooperates with the spacing screw slot of tailstock mandrel 8.
During the processing radial hole, spacing screw rod 16 holds out against at the bottom of the spacing screw slot of tailstock mandrel 8 (see figure 4)s, and locking nut 12 is tightened, and has limited moving axially and circumferentially rotating of tailstock mandrel 8.Thereby guaranteed the position relation between radial hole and the eccentric orfice.
When unloading workpiece, unclamp locking nut 12, and unscrew spacing screw rod 16.
(4) dividing head assembling
Be made up of dividing head mandrel 10, dividing head 11, assembly relation is seen Fig. 3.This assembling has realized the axial location of lean pipe 9.
More than the assembly relation of 4 little assemblings see Fig. 3,4,5.The synergy of these 4 little assemblings has realized the processing of lean pipe 9 radial holes.
