Specific embodiment
Technical solution of the present invention is further described below with reference to specific example, but not as to technical side
The limitation of case.
It is illustrated by taking 50 double-screw extruder screw of section Asia φ as an example, screw diameter 50mm, screw head diameter 30mm.
Flange outer diameter 260mm, centre bore internal diameter 100mm, periphery are uniformly provided with 6 12 through-holes of Φ and 50 extruder of section Asia φ
The matching of barrel mounting hole；The threaded hole of 2 M25 is symmetrically opened on horizontal center line as guide rail mounting hole；On vertical center line
1 40 hole Φ Fang Kaiyou, embedded bearing, for fixing lead screw.
Back seat is "convex" shaped structure, and long 210mm, high 150mm are provided with 2 M25 threaded holes with flange corresponding position and are used for
Fixed guide rail, 1 40 hole Φ, embedded bearing are installed for lead screw.
Locking bed is identical as back seat shape, and a pair of of 35 hole Φ, embedded bearing, for leading is respectively set with back seat corresponding position
Rail passes through and 1 40 hole Φ, embedded bearing, installs for lead screw, threaded puller bolt hole is arranged on guide rail hole line,
Setting mounting hole corresponding with locking jacket simultaneously, for fixing locking jacket；
Locking jacket is " ∞ " jacket cylinder, and gabarit major diameter is 92mm, and minor axis 32mm, inner cavity is that a pair of of mouth diameters are
30.3mm, base diameter are 31.2mm through-hole, through-hole spacing and screw rod pitch match to be removed；
Locking inner sleeve is band round-ended cylinder, and intracavity diameter 30mm, oral area outer diameter is 30.4mm, and with a thickness of 2mm, bottom outer diameter is
31.1mm, with a thickness of 5.5mm, oral area is symmetrically provided with the rectangle longitudinal extension slot of 2 1.5mm；
After locking inner sleeve and locking jacket taper are embedded in locking jacket in the same direction, locking jacket is fixed on locking bed, is pushed up
The M12 bolt that tight bolt is length 100mm, out of the other side insertion locking bed threaded hole.
Lead screw is the Φ 30*10 ball-screw of length 1600mm, is each passed through back seat and locking bed, one end warp by bearing
Bearing and flanged joint, the other end install handwheel.Lead screw is vertical with back seat, locking bed.
