The operation principle that this utility model end cap captures is: horizontal movement platform 2 horizontal movement, passes through horizontal displacement
Sensor 14 controls the distance of its horizontal movement, and radial motion platform 3 radial motion, passes through radial displacement afterwards
Sensor 12 controls the distance of its radial motion, finally realizes the centralized positioning of down-pressed pole assembly 72 and end cap 101,
Down-pressed pole assembly 72 moves downward afterwards.
End cap location bar 744 be can retraction rod, when capturing end cap 101, end cap location bar 744 and end cap 101
Hole, location when staggering, as it is shown on figure 3, end cap location bar 744 bounces back, touch and be built in end cap handgrip
During pressure transducer, pressure transducer sends signal and then control down-pressed pole assembly 72 rotates in a circumferential direction, and then drives
End cap handgrip 74 rotates in a circumferential direction, when end cap location bar 744 and location hole centering, and end cap location bar 744 resilience,
Complete the circumferentially positioned of end cap handgrip 74 and end cap 101.
Owing to end cap 101 is cast member, its outer surface is all non-machined surface except screwed hole boss, therefore, at end
During lid 101 assembling, select 745 times pressure side lids 101 of the 1st locating surface, as shown in Figure 4, Figure 5, again due to end
Lid 101 is thin-wall part, and week, downward pressure side lid 101 easily made it deform, and therefore, selected the 2nd locating surface 746
As the lower pressure surface of auxiliary, complete with the location of end cap 101 after, movable handgrip drives motor 743 driving activity to grab
Hands 742 radial motion, completes the clamping of end cap, and down-pressed pole assembly 72 moves upward to certain altitude afterwards.
Owing to the center of end cap 101, rotor assembly 102 and case component 103 is on a horizontal line, complete
After becoming the grasping movement of end cap 101, only need to send signal by horizontal displacement sensors 14, control horizontal movement
The motion of platform 2 can complete the centralized positioning of rotor grabbing assembly 8 and rotor assembly 102.Rotor grabbing assembly
After 8 are moved downwardly to certain position, under the drive of two-way cylinder 83, rotor handgrip 82 captures rotor assembly 102,
And move upward.
When rotor driven assembly 102 upwards time, rotor fixed position bar 728 blocks the keyway of rotor assembly 102 upper end,
Complete the location of rotor assembly 102 and end cap 101, so, when assembling rotor assembly 102, on rotor assembly
The location of positioning threads bar and case component 103, just can be by the location of end cap location bar 744 with case component
Realize.
It is that push rod 92 moves upward and withstands that the centralized positioning of rotor assembly 102 and case component 103 realizes process
Rotor assembly 102, separately, down-pressed pole assembly 72 moves downward rotor handgrip 82 with push rod 92 simultaneously afterwards,
When end cap location bar 744 is to position shown in Fig. 9, end cap location bar 744 is wrong with the hole, location of case component 103
Opening, its location mode as the location mode of end cap 101, completes end cap 101 and machine with end cap location bar 744
Shell component 103 circumferentially positioned.Left block 724, right block 725 are coordinated by inclined-plane with movable depression bar 722,
After having been assembled by rotor assembly 102, left block drives motor 726, right block to drive motor 727 to carry respectively
Left block 724, right block 725 radial motion, so, rotor assembly 102 is withstood in movable depression bar 722 one end,
The other end withstands spring 723, and depression bar body 721 can continue down moved end cap 101 and case component 103
Assembling, its installation diagram completed is as shown in figure 11.
