The specific embodiment
Like Fig. 1 and shown in Figure 4; The automatic modified gear of a kind of block, it comprises the tensioner belt wheel 35 and driving pulley 3 that is arranged at track base 36 two ends respectively, driving pulley 3 is driven by the servomotor output shaft; Tensioner belt wheel 35 and driving pulley 3 are with 4 transmissions synchronously through what hold the two; Block 28 is set on the take-up housing 22 of line slideway slide block 39 and with synchronously with 4 small pulleys 8 that cooperate, small pulley 8 is provided with arrangement of clutch, this arrangement of clutch realize small pulley 8 with synchronously with 4 combination with separate.Motor bearing 5 and expansion tightening wheel bearing 34 are fixed on the two ends of track base 36 through screw, and servomotor 1 is fixed on the motor bearing 5, be with synchronously 4 with driving pulley 3 and 35 engagements of tensioner belt wheel, regulate expansion tightening wheel bearings 34 by tightening piece 30 and come tensioner to be with 4 synchronously; Said support set 9 turn 90 degrees placement for the dextrorotation of hollow convex shape, in support set 9 left part cavitys, bearing 16 is set, the inner ring tight fit of the outer ring of bearing 16 and support set 9; Friction sleeve 15 and external friction cover 10 in said arrangement of clutch comprises, the outer ring of external friction cover 10 and the inner ring tight fit of bearing 16; Small pulley 8 is fixedly connected with external friction cover 10; One have positioning key 37 axle 11 pass successively in friction sleeve 15, external friction cover 10 is connected with cylinder 12 piston rods with support set 9, cylinder piston rod shrinks interior friction sleeve 15 and external friction and overlaps 10 and hold tightly through friction; The inwall of support set 9 all has keyway with axle on 11, and positioning key 37 cooperates with the keyway of support set 9 axle 11 is positioned and leads; Interior friction sleeve 15 is fixedly connected with axle 11; The position that on axle 11, is arranged in external friction cover 10 is provided with compression spring 13.Interior friction sleeve 15 is connected with axle 11 through key 38.
As shown in Figure 2, saidly be meant and on take-up housing 22, be connected with gripper shoe 14 in that small pulley 8 is set on the take-up housing 22, be fixedly connected with support set 9 on the gripper shoe 14, small pulley 8 is set on support set 9.
The cylinder 12 that on gripper shoe 14, fixedly installs magnetic valve 24 and controlled by magnetic valve 24, said arrangement of clutch is connected with the piston rod of cylinder 12.
As shown in Figure 7, the symmetrical mounting bracket 21 of difference in the take-up housing both sides, minor axis 27 is being installed under the support of little bearing 40 on the support 21, and minor axis 27 is distributed in the both sides of small pulley 8.Synchronously with 4 walk around minor axis 27 and small pulley 8 engagements increase small pulley 8 cornerite, increase small pulley 8 and, make transmission more steady synchronously with 4 total number of teeth in engagement.
Directly control servomotor 1 through the control system, see Fig. 5, the axle of servomotor 1 is connected through key with driving pulley 3, and 4 transmissions are with in the rotation drive of servomotor 1 synchronously.Produce the displacement that power can be controlled block respectively with 4 with the engagement of small pulley 8 synchronously; Small pulley 8 is controlled through arrangement of clutch and is seen Fig. 4; This arrangement of clutch is directly controlled magnetic valve 24 through the control system and is come the flexible of control cylinder 12 piston rods, can realize the automatic displacement of each back backgauge block through this arrangement of clutch.
When block needs displacement; See Fig. 3 and Fig. 4; Solenoid control cylinder piston rod contraction bands moving axis 11 compression springs 13; At the inboard positioning and guidings that play a part of support set 9, interior friction sleeve 15 is connected with axle 11 through key 38 axle 11 through positioning key 37, and cylinder piston rod shrinks interior friction sleeve 15 and external friction and overlaps 10 and hold tightly through friction; Bearing 16 inner rings can not change.Small pulley 8 is fixed through screw through gland 7 and external friction cover 10; The outer ring of external friction cover 10 and the inner ring tight fit of bearing 16; The inner ring tight fit of the outer ring of bearing 16 and support set 9 supports cover 9 to be fixedly connected with gripper shoe 14, and gripper shoe 14 is connected on the take-up housing 22 of line slideway slide block 39; Be connected with block 28 on the take-up housing 22, small pulley 8 links together with block 28.So be with 4 transmissions synchronously when servomotor 1 main shaft drives to drive when driving pulley 3 rotates; With synchronously with the small pulley 8 of 4 engagements since the inner ring of bearing 16 can not rotate; So small pulley 8 can only be realized the displacement of block 28 along with on line slideway 20, doing rectilinear motion with the block 28 on the 4 drive take-up housings 22 synchronously.
When block does not need displacement, see Fig. 3, the magnetic valve dead electricity; Cylinder piston rod resets by compression spring 13, the cylinder piston rod elongation, and interior friction sleeve 15 was opened with the external friction cover in 10 minutes; 10 outer ring tight fits are overlapped in bearing 16 inner rings and external friction; Bearing 16 outer rings and support set 9 inner ring tight fits, because external friction cover 10 is separated with interior friction sleeve 15, the inner ring of bearing 16 can rotate; Support cover 9 and gripper shoe 14 take-up housings 22 to interconnect, take-up housing 22 is fixed on the slide block 39, so support set 9 can only be done rectilinear motion along guide rail 20; When driving to drive when driving pulley 3 rotates, servomotor 1 main shaft is with 4 transmissions synchronously; With synchronously with the small pulley 8 of 4 engagements since the inner ring of bearing 16 can rotate; So small pulley 8 is along with being with 4 to rotate synchronously; Skidding appears in small pulley 8, and the slide block 39 that is connected on the take-up housing 22 is static on guide rail 20.
See Fig. 2 and Fig. 3, the position of block 28 displacements, near switch I 41 with between near switch II 44, switch frame 43 is fixed on the track base 36, is fixed near switch on the U type groove of switch frame 43; Tablet 42 is connected with take-up housing 22; Tablet 42 moves with block 28; Near switch I 41 with near switch II 44 are two extreme positions of block 28, have realized that block positions the plate of Breadth Maximum and the plate of minimum widith, and two extreme positions also are the reference positions of block 28.When tablet 42 when contacting near switch; Signal feedback near switch is given system as a reference; By the displacement of the parameter set in system control block, to the automatic displacement of plate block of different in width, guarantee more accurately each block the distance that will move.
Said, every cover arrangement of clutch all has independent solenoid control, directly controls the elongation and the contraction of the cylinder piston rod that every group of magnetic valve link to each other through the control system, and block can be adjusted displacement as required automatically.Interstage sleeve 2, back-up ring 6, back-up ring 17, bearing cap 31, axle bumper cover 33 play the role of positioning, and gland 7 plays the positioning dust-proof effect.Screw on the regulating block 23 can guarantee post 29 and the positioning accuracy of plate contact point on same horizontal linear to the fine setting of plate 26 front and back.
