The quartz ingot lifting apparatus is by rack 1, slide 2, rotation lift mechanism, driving screw rod 3, splined shaft 4 and clump weight 5
It constitutes (referring to Figure of description 1,2 and 3).
Slide 2 is slidably fitted with by upright slide rail 6 in rack 1；Equipped with rotation lift mechanism on slide 2；Rotation is lifted
Mechanism is made of reverse box 11, supporting plate 12, adjustment frame, kinematic link 13, universal joint 14 and support shaft 15 (referring to explanation
Book attached drawing 5).
Adjustment frame (referring to Figure of description 5 and 6) is housed on slide 2；Adjustment frame is by shield 20, cross slide 21 and indulges
It is constituted to slide plate 22.
Shield 20 is fixed on slide 2；Cross slide 21 is equipped with by the sliding of horizontal slide rail 23 in shield 20；Laterally
Longitudinal slide 22 is equipped with by the sliding of longitudinal slide rail 29 on slide plate 21.
It is equipped on the slide 2 of 21 side of cross slide by assembling stand activity and laterally adjusts screw rod 24；Laterally adjust screw rod
24 one end is threadedly coupled with cross slide 21；When turn laterally adjusts screw rod 24, adjustment screw 24 can drive cross slide 21
Transversely sliding rail 23 moves back and forth.
Longitudinally adjusted screw rod 25 is movably installed with by assembling stand on the cross slide 21 of 22 side of longitudinal slide；It is longitudinal to adjust
Whole screw rod 25 is threadedly coupled with longitudinal slide 22；When the longitudinally adjusted screw rod 25 of turn, longitudinally adjusted screw rod 25 can drive longitudinal cunning
Sliding rail 29 moves back and forth plate 22 along longitudinal direction.
By bearing block 16 equipped with support shaft 15 on longitudinal slide 22；Cross slide 21 and longitudinal slide 22 is arranged such
Purpose be: so that people are by the longitudinally adjusted screw rod of turn 25 and laterally adjust screw rod 24, reach adjusting support shaft 15
The purpose of position, to make to support the supporting plate 12 in shaft 15 corresponding with quartzy ingot.
The mode that the upper end of support shaft 15 is connected through a screw thread is fixed with supporting plate 12；Bearing block 16 and support shaft 15 are worn
The lower section of slide 2 is extended to after the adjustment hole crossed on cross slide 21；The aperture of adjustment hole is greater than the outer diameter of bearing block 16, so
Certain space can be provided for the movement of bearing block 16, drive bearing block 16 and support shaft so as to avoid longitudinal slide 22
In 15 moving process, the problem of interfering collision with cross slide 21.
The bottom end of bearing block 16 is fixed with reverse box 11；Support the lower end of shaft 15 and the output of reverse box 11
End connection.When the rotation of the input terminal of reverse box 11, the output end of reverse box 11 can drive support shaft 15 synchronous
Rotation.
Transmission shaft 17(is equipped with referring to Figure of description 5 by bearing block 16 on the slide 2 of 11 side of reverse box)；It passes
One end of moving axis 17 is connected with kinematic link 13 by universal joint 14.
Kinematic link 13 is made of spline connecting rod 26 and link rod sleeve 27；It is slidably installed in link rod sleeve 27 by spline
There is spline connecting rod 26；Opposite slide can occur when spline 26 stress of connecting rod with link rod sleeve 27；One end of spline connecting rod 26 passes through
Universal joint 14 is connect with transmission shaft 17；The other end of link rod sleeve 27 is connected by the input terminal of universal joint 14 and reverse box 11
It connects.The purpose that kinematic link 13 is arranged such is: first is that enabling transmission shaft 17 will by universal joint 14 and kinematic link 13
Power is sent to the input terminal of gear-box 11；Second is that adjusting support by laterally adjusting screw rod 24 and longitudinally adjusted screw rod 25 and turning
During the position of axis 15, reverse box 11 can be relatively moved with transmission shaft 17；It so can avoid kinematic link 13
When in straight-bar, kinematic link 13 hinders the generation of the mobile problem of reverse box 11.
Spline housing 18 is equipped with by bearing block 16 on the slide 2 of 17 side of transmission shaft；18 inside of spline housing and splined shaft 4 are sliding
Dynamic engagement connection；During slide 2 is moved up and down along upright slide rail 6, spline housing 18 can be driven in flower by bearing block 16
It is moved up and down on key axis 4；And in this course, spline housing 18 can be driven to rotate synchronously when splined shaft 4 rotates.
It is connect by taper gear pair 19 with one end of transmission shaft 17 outside spline housing 18.Splined shaft 4 can pass through when rotating
Spline housing 18 and taper gear pair 19 drive transmission shaft 17 to rotate synchronously.
By lead screw motor 7 and speed reducer equipped with driving screw rod 3, driving screw rod 3 and slide 2 in the rack 1 of 2 side of slide
It is threadedly coupled (referring to Figure of description 3)；Lead screw motor 7 can drive driving screw rod 3 to rotate when working by speed reducer；Drive silk
Slide 2 can be driven to move up and down in rack 1 along upright slide rail 6 in 3 rotation process of bar.
Drive 3 side of screw rod that splined shaft 4 is housed by driving motor 8 and speed reducer；Splined shaft 4 and rotation lift mechanism
Spline housing 18 connects.Splined shaft 4 is driven to rotate when driving motor 8 acts.
It drives in the rack of 3 side of screw rod and is shelved with clump weight 5；Leading block 9 is housed in the rack 1 of 5 top of clump weight；
Traction steel wire 10 has been tied on clump weight 5；One end of traction steel wire 10 connect (ginseng with the upper end of slide 2 after bypassing leading block 9
See Figure of description 2).
In the rack 1 of 2 upper end of slide and flexible seal closure 28 is respectively provided in the rack 1 of 2 lower end of slide；Each flexible sealing
Cover 28 is connected with slide 2 respectively.Each flexible seal closure 28 is made of the seal closure monomer of multiple mutual pivot bush units (says respectively
Do not show in bright book attached drawing)；Its function of having contraction or elongation when flexible 28 stress of seal closure；Flexible seal closure 28 is set
Purpose is: first is that rack 1 is isolated from the outside world, avoiding extraneous dust (impurity), enters the internal influence driving of rack 1
The rotation of screw rod 3 and splined shaft 4；During two move up and down slide 2, the seal closure 28 that stretches being capable of moving with slide 2
Make and act, the generation of the movement problem of slide 2 is hindered so as to avoid flexible seal closure 28.
The quartz ingot lifting apparatus adjusts supporting plate by laterally adjusting screw rod 24 and longitudinally adjusted screw rod 25 first when work
12 position keeps it corresponding with the quartzy ingot discharge port of combustion furnace.Subsequent start-up lead screw motor 7 and driving motor 8；Screw rod electricity
Slide 2 is driven slowly to move down along upright slide rail 6 by driving screw rod 3 when machine 7 works；Driving motor 8 drives spline at the same time
Axis 4 rotates synchronously；Pass through spline housing 18 in 4 rotation process of splined shaft, taper gear pair 19, transmission shaft 17, kinematic link 13, change
Supporting plate 12 is driven to rotate synchronously to gear-box 11 and support shaft 15；It can so be realized during rotation by supporting plate 12
Lift the purpose that quartzy ingot moves down；Meet the needs of production and application.
The quartz ingot lifting apparatus structure is simple, easy to use, makes driving motor far from high-temperature area, solves existing
The high failure rate and repair frequent problem that lifting apparatus has when motor is mounted on slide, meet enterprise's production and application
It needs.
