Detailed description of the invention
The technical program a kind of vertical steel ball process equipment drives the pull-down pressuring machine of top lap pressurization by leading screw
Structure, servo deceleration motor drives one group of synchronous pulley, and big synchronous pulley passes through feed screw nut, drives leading screw to rotate, and leading screw drives
Top lap moves up and down；After top lap contacts with lower rotation dish, top lap and leading screw are not moving, feed screw nut meeting
Moving up under synchronous pulley drives, by a thrust bearing and disc spring, by pressure transmission to top lap, pressure is steady
Fixed, disc spring pressurize, the precise displacement of leading screw improves the accuracy of pressurization, and ensures to realize ball lapping machine maximum tonnage
40kN.Servo deceleration motor is arranged on lathe bed right back, also reduces the whole height of lathe simultaneously.It is embodied as such as Fig. 1
Shown in, leading screw 12 is sequentially connected lockhole nut 1 from top to bottom, has promoted spheric roller bearing 2, top board 3, feather key 4, dish
Spring abutment 11, disc spring pad 14, disc spring 15, bearing block 16, thrust ball bearing 17, feed screw nut 18, big synchronous pulley 21, further
Saying, the upper end of leading screw 12 has feather key 4, and leading screw 12 loads top board 3 by feather key, and the boss of described top board assembles
Having upper guide plate 5, described upper guide plate 5 is below equipped with the flange of emery wheel 6, and the two ends of top board 3 are respectively provided with spherical roller thrust axle
Holding 2, the top of leading screw, equipped with locking nut 1, carries out locking positioning, and the lower end of described leading screw 12 penetrates in disc spring seat 11, disc spring
Seat is arranged on lathe bed 7, and the top of described disc spring seat is equipped with gland 8 and lips tetrafluoro dust ring 9, described lips tetrafluoro dust ring
On equipped with dust cap 10, it is therefore an objective to preventing from entering in leading screw lapping liquid, the bottom of leading screw is equipped with plain cushion 14, disc spring 15 and bearing block
16, disc spring seat 11 is fastened on bed equipped with thrust ball bearing 17 and feed screw nut 18 and by ring flange 20 in described bearing block 16
On body 7, equipped with expansion sleeve 23 on the big synchronous pulley 21 of feed screw nut lower end, its motion comes from servo deceleration motor 25, band
Dynamic small synchronous pulley 24 transmits, and furtherly, is connected by belt between big synchronous pulley 21 and small synchronous pulley 24, and servo subtracts
Output shaft on speed motor 25 is connected with small synchronous pulley, and leading screw is to be ensured lubrication by the screw rod lubrication pipe 13 of dress on it.
As it is shown in figure 1, the upper end of leading screw 12 is in quick condition, servo deceleration motor 25 drives small synchronous pulley 24
Feed screw nut 18 rotary motion is made, say, that feed screw nut on the premise of disc spring is not by compression with big synchronous pulley 21
The convert rotational motion of 18 is that leading screw drives top board to move up and down with upper guide plate 5, is pressurized to and emery wheel when upper guide plate 5 moves down
After 6 contacts, upper guide plate 5 no longer moves, and leading screw 12 the most no longer moves, and now feed screw nut 18 is owing to floating upper end, big Timing Belt
Wheel 21 its continuation of drive rotates, and feed screw nut 18 rotates along with moving on leading screw, and feed screw nut is slowly upper to be moved, and disc spring 15 is slowly pressed
Contracting, then by pressure actuation top board and upper guide plate, thus reaches the purpose of dish pressurization, when upper guide plate separates with emery wheel 6,
Feed screw nut 18 first rotates and moves down, and waits that disc spring is replied normal, and feed screw nut the most only rotates, and is not moving down, and leading screw
12 drive top board to move up with upper guide plate 5, enter the release stage.
Equipped with proximity switch 19 in mechanism, described proximity switch is contained in the adjacent of ring flange 20, can control system maximum
Pressure and the maximum displacement of big synchronous pulley 21, come accurate by the closed loop system of displacement transducer 22 and servomotor 25
Control system pressure and feeding displacement.
Described gland 8, lips tetrafluoro dust ring 9, waterproof cover 10 are protection device, prevent leading screw from entering lapping liquid, it is ensured that
The feeding progress of leading screw.
