Below in conjunction with accompanying drawing to the invention each several part the operating process that rises and operation principle be described in detail.
The first step has been the adjustment of overall setup workbench, and the object of adjustment is the level and the upright position that ensure each parts.Frame as the support standing part of overall setup, the key component of the adjustment of overall setup workbench.The operation principle of frame: as shown in Figure 2, installing plate ensure that the level of whole mechanism to frame, and vertical plate, top plate supporting fix other each several parts, reinforcement ensure that the level of the vertical of vertical plate and top board respectively.Guide rail on vertical plate can grip mechanism to undercarriage piston rod and angle-adjusting mechanism leads, and ensures that these two parts move up and down in the Z-axis direction along vertical guide rail.
Second step has been the reset zeroing of overall setup, makes each parts get back to work origin, prepares assembly work.Lift cylinder is the key component of the reset zeroing realizing overall setup, and undercarriage piston rod can be driven to grip mechanism for it and angle-adjusting mechanism is elevated along Z axis, makes two mechanism kinematics to work origin.Operation principle: the piston rod of lift cylinder drives undercarriage piston rod to grip mechanism and angle-adjusting mechanism moves up and down along Z axis, the lifting that undercarriage piston rod grips mechanism and angle-adjusting mechanism is realized in assembling process, thus realize piston rod lift adjustment, make them move to work origin.
Second step is gripping of undercarriage piston rod and urceolus.Undercarriage piston rod grips mechanism and urceolus, and to grip mechanism be the key component gripped realizing undercarriage piston rod and urceolus, they realize gripping different-diameter undercarriage piston rod and urceolus respectively, and the even of 3 chucking powers can both be ensured, and fine adjustment can be carried out to chucking power.First undercarriage piston rod grips mechanism below.
Grip the operation principle of mechanism: upper mounted plate 218 and bottom plate 219 are fixed by link 217, what realize that upper mounted plate 218 and bottom plate 219 move is synchronous.Initiatively tooth bar 26 engages with two driving gears 22, two driving gears 22 engage with corresponding driven gear 23 respectively, driven gear 23 engages with corresponding driven tooth bar 7 again respectively, and two driven tooth bars 27 slidably reciprocate on bottom plate 219 by guide-track groove 25.Piston rod 51 drives initiatively tooth bar 26 to move, initiatively tooth bar 26 drives driving gear 22, driven gear 23, driven tooth bar 27 to move, final driven tooth bar 27 drives clamping unit to move, three screw elements 42 are just all tangent with the face of cylinder of undercarriage piston rod, three points of tangency, in same plane, realize gripping of undercarriage piston rod and urceolus.
The clamping to different-diameter undercarriage piston rod is realized: piston rod does stretching motion in assembling process, when driving initiatively tooth bar motion, through a series of transmission, three clamping units axially outwards move along it simultaneously, regulate like this and can clamp the larger undercarriage piston rod of diameter; Piston rod does contractile motion, and when driving initiatively tooth bar motion, through a series of transmission, three clamping units axially outwards move along it simultaneously, regulate like this and can clamp the less piston rod of diameter.We according to by regulating servo-electric cylinder piston rod to do stretching motion, when driving initiatively tooth bar motion, through a series of transmission, axially outwards can move along it the while of three clamping units, having carried out the clamping of different-diameter undercarriage piston rod.
Ensure 3 chucking powers evenly and can fine adjustment: because the size of mechanism 4 gears is identical, the size of 2 driven tooth bars is also identical, and the angle between three tooth bars is 120 °, then the position of these three chucking powers all with the axes intersect of piston rod, and in 90 ° of angles.These three power are applied on same point, make a concerted effort to be 0, and size are completely equal.Suppose that the power that servo electric jar provides is F, then the size of three chucking powers is F/3, and we realize carrying out fine adjustment to chucking power by regulating the power F of servo electric jar.
Urceolus grips mechanism, and the end face of three studs is just all tangent with the face of cylinder of urceolus, and three phase tangent lines are parallel to each other, thus makes urceolus keep vertically, achieving gripping of urceolus.Urceolus grips the operation principle of mechanism, clamp method, chucking power regulate that to grip mechanism with piston rod identical.
3rd step adjusts the height of undercarriage piston rod and angle, finds optimum assembling position.This step is divided into two parts: the Height Adjustment of piston rod and the adjustment of piston rod angle.
First be the Height Adjustment of piston rod: lift cylinder realizes undercarriage piston rod Height Adjustment key component, and it can drive undercarriage piston rod to be elevated along Z axis, undercarriage piston rod movement is to best assembling height.Servo electric jar bar drives piston rod to move downward along Z axis, till the lower surface of undercarriage piston rod overlaps with the upper surface of urceolus.
Next is the end plane angle adjustment of undercarriage piston rod: undercarriage piston rod end face angle-adjusting mechanism realizes piston rod end face angle adjustment key component, and it can realize piston rod and adjust along the direction of X-axis, Y-axis.
Undercarriage piston rod adjusts along the orientation angle of X-axis: the servo electric jar level in X-axis is moved to positive direction, its clamping unit heads on undercarriage piston rod and deflects to positive direction, undercarriage piston rod press against X-axis upper ejector pin level and moves to positive direction, and in X-axis, spring is compressed; In X-axis, servo electric jar level is moved to negative direction, is in compressive state because spring in X-axis compresses always, and deflect so X-axis upper ejector pin clamping unit heads on undercarriage piston rod to negative direction, X-axis upper ejector pin moves to negative direction.
Undercarriage piston rod adjusts along the orientation angle of Y-axis: the servo electric jar level in Y-axis is moved to positive direction, its clamping unit heads on undercarriage piston rod and deflects to positive direction, undercarriage piston rod press against Y-axis upper ejector pin level and moves to positive direction, and in Y-axis, spring is compressed; In Y-axis, servo electric jar level is moved to negative direction, is in compressive state because spring in Y-axis compresses always, and deflect so Y-axis upper ejector pin clamping unit heads on undercarriage piston rod to negative direction, Y-axis upper ejector pin moves to negative direction.
4th step is by undercarriage piston rod press-in urceolus, completes assembling.Assembling actuating unit realizes the key component of this step.Assembling cylinder operation principle: the piston rod of assembling cylinder moves downward along Z axis, and clamping unit press against the upper surface of undercarriage piston rod, is pressed in urceolus straight down, completes assembling, the degree of depth of press-in regulates by assembling cylinder.
The foregoing is only the preferred embodiment of the invention; not in order to limit the invention; within all spirit in the invention and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in the invention.
