12,12 top of movable plate is flushed with monitor station 5, and movable plate 12 digs 10 bottom of Shi Huiyu two pressure plates and offsets；Movable mouth
Left side is fixedly connected with supporting block 13, and supporting block 13 is for being supported movable plate 12.Level slidably connects in cavity 11
Movable block 14, movable block 14 are equipped with the first lozenges 17 and the second lozenges 18, the first lozenges 17 and the second lozenges 18
It is oppositely arranged.Guide plate 20 is fixed in cavity 11, guide plate 20 is located at the top of movable block 14, slides vertically on guide plate 20
It is connected with mandril 19, the bottom of mandril 19 is matched with the first lozenges 17, and the top slide of mandril 19 is connected to movable plate 12
Bottom.The right side of monitor station 5, which slides vertically, is connected with locating rod 21, and the top of locating rod 21 is equipped with cushion collar, locating rod 21
Bottom penetrates in cavity 11 and matches with the second lozenges 18, and locating rod 21 is opposite with 19 position of mandril.The front side of monitor station 5
Horizontally disposed notch 16 is offered on face, notch 16 is connected to cavity 11；Push rod 15, push rod are fixedly connected on movable block 14
15 sides far from movable block 14 are pierced by notch 16 and level is slidably connected in notch 16.Push rod 15 far from movable block 14 one
End is connected with noose 23, strut 24 is fixedly connected on the left of notch 16, noose 23 is socketed on strut 24.It is connected on pressing plate 10
Drawstring 22, the other end of drawstring 22 pass through 5 front side left part of monitor station and are fixed on movable block 14.
When initial, 12 left bottom of movable plate offsets with supporting block 13, movable plate 12 be in horizontality and with monitor station 5
Top surface flushes, and the top of locating rod 21 is pierced by monitor station 5 at this time, and the top of locating rod 21 is higher than the top surface of monitor station 5, so as to
Position-limiting action is played to the keyboard board 25 being put on monitor station 5.At this point, push rod 15 is located at the left end of notch 16, noose 23
It is socketed in strut 24；(i.e. 19 distance from top movable plate of mandril, 12 bottom surface does not have centainly with 12 bottom of movable plate at the top of mandril 19
Distance), pressing plate 10 is close to monitor station 5 and limited block 7 is located on monitor station 5.
When needing to detect keyboard board 25, noose 23 is removed from strut 24 first, is then pushed away to the right
Bar 15 pulls pressing plate 10 by drawstring 22 when movable block 14 moves to right, to make pressing plate 10 so that movable block 14 moves to right certain distance
On limited block 7 gradually separated with monitor station 5, the open-shaped state of pressing plate 10, work of the locating rod 21 in the second lozenges 18 at this time
Certain distance is moved down under, but the top of locating rod 21 is still higher than 5 top surface of monitor station, and mandril 19 is in the first lozenges
A certain distance is moved up under the action of 17, but 19 top of mandril does not still offset with movable plate 12, so movable at this time
Plate 12 is not flipped, and keyboard board 25 can be put on monitor station 5 by operator, and is made the right side of keyboard board 25 and determined
Position bar 21 offsets, to realize the Primary Location of keyboard board 25.
Then, push rod 15 is pushed to reset movable block 14 to the left, movable block 14 is resetted by drawstring 22 with dynamic pressure plate 10, from
And limited block 7 is allowed to be pressed on keyboard board 25, so that electromagnet 6 is powered at this time, electromagnet 6 is realized by the cooperation with limited block 7
Further positioning to keyboard board 25, prevents keyboard board 25 from shifting in the detection process.Meanwhile noose 23 being socketed again
Onto strut 24, movable block 14 is positioned, keyboard board 25 is further prevented to shift in the detection process.At this point, mandril
19 and locating rod 21 return to initial position.
Then, the motion profile of manipulator 8 is controlled by teaching machine 3, and grab is examined by digital display dial gauge 9
It surveys, and will test data and be transferred in computer 4, shown by the display of computer 4.This process and embodiment 1
Process is identical, is not repeated herein.
After the completion of keyboard board 25 detects, noose 23 is taken off from strut 24, pushes push rod 15 to the right, make push rod 15
It is moved to the right end of notch 16, locating rod 21 moves gradually downward along the second lozenges 18 during this, the top of locating rod 21
Portion is flushed with 5 top surface of monitor station, at this point, mandril 19 gradually offsets with the bottom plate of movable plate 12 and pushes work in conjunction with shown in attached drawing 5
Movable plate 12 is flipped up, and the left end of keyboard board 25 is propped up to come, so that keyboard board 25 be allowed to skid off from the right side of monitor station 5.
Movable plate 12 will push pressing plate 10 during being flipped up and be flipped up, so that limited block 7 is allowed to be gradually distance from monitor station 5,
Meanwhile movable block 14 pulls pressing plate 10 to stir upwards during moving right also by drawstring 22, makes limited block 7 gradually remote
From monitor station 5, after keyboard board 25 loses the limit of pressing plate 10, limited block 7 and locating rod 21, the meeting under the promotion of movable plate 12
It slides to the right, to leave the detection station of monitor station 5.If keyboard board 25 slides to have some setbacks to the right, operator can also
Keyboard board 25 to be removed manually, since the left side of keyboard board 25 at this time has been dug, operator can it is very convenient,
Rapidly keyboard board 25 is removed, and keyboard board 25 will not be damaged.
After the keyboard board 25 leaves the detection station of monitor station 5, operator can push push rod 15 mobile one to the left
Set a distance makes 21 top of locating rod be pierced by monitor station 5 again, and pressing plate 10 at this time is still within the state dug, limited block 7
It is separated with monitor station 5.At this point, another piece of keyboard board 25 to be detected is put into detection station by operator, make keyboard
The right end of bottom plate 25 is contacted with locating rod 21 and left end is located on movable plate 12, while keyboard board 25 being made to be located at two pressure plates 10
Lower section.
Then, continue to push push rod 15 to be moved to the left movable block 14 to the left, push rod 15 is allowed to be moved to the left end of notch 16.
Mandril 19 is moved gradually downward along the first lozenges 17 and is separated with 12 bottom of movable plate during this, and movable plate 12 is gradually extensive
Again to the position flushed with 5 top surface of monitor station, and locating rod 21 then gradually moves up along the second lozenges 18 and continues to wear
Monitor station 5 out make to be higher by 5 a certain distance of monitor station at the top of locating rod 21, to enhance locating rod 21 to keyboard board 25
Position-limiting action.At this point, keyboard board 25 is horizontally located on monitor station 5, digital display dial gauge 9 can be to the grab on keyboard board 25
It is detected.
What has been described above is only an embodiment of the present invention, and the common sense such as well known specific structure and characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these also should be considered as protection scope of the present invention, these all will not influence what the present invention was implemented
