One briquetting 703 and a fixed block 704；Each 702 piston rod end of compression cylinder is pierced by downwards support plate 701 and and briquetting
703 are sequentially connected, and each briquetting 703 is sequentially connected with the fixed block of lower section 704 realizes that oriented sliding is connect again；Compression cylinder
702nd, briquetting 703 is collectively referred to as pedestal compressing unit with fixed block 704, and all pedestal compressing units are being located at positioning plate 803 just
Top, there are one positioning fixtures for each 704 lower face of fixed block setting.
Such as Figure 17, the structure of positioning fixture is to be included in bottom plate 709 there are one each 704 lower face of fixed block fixations, often
A 709 lower surface of bottom plate is provided with 4 the second raised items 706 side by side, and it is U-shaped to be equipped with second between adjacent second raised item 706
Slot 707 is provided with groove in second U-type groove 707, and positioning pin 708,708 bottom of positioning pin and place groove are provided in the groove
Spring is provided between bottom；
The width of second raised item 706 is matched with the width of the pole slot 108 of 1 upper surface of pedestal, the width of the second U-type groove 707
Degree is matched with the width of the first raised item 109 on pedestal 1；Positioning pin 708 is matched with the location hole 107 on pedestal 1；Due to cunning
Bar 705 is passed through from fixed block 704, and spring, therefore positioning fixture are provided between 708 bottom of positioning pin and bottom portion of groove
And the height of positioning pin 708 can be finely adjusted according to the actual height of pedestal 1, prevent from damaging by pressure pedestal 1.
Above-mentioned each mechanism is connect with central controller, receives the instruction being uniformly coordinated, and realizes step-type operation.
The present invention the course of work be,
1) pedestal 1 for assembling part product is transmitted to 803 arrival end of positioning plate, positioning plate 803 by feeding conveying belt 801
Cylinder 1, cylinder 2 15 and cylinder 3 16 on the side plate of both sides stretch out simultaneously, and each fixture block 19 is stuck in the both sides of pedestal 1, will
Pedestal 1 clamps；The piston rod of cylinder 4 17 stretches out, and positioning slide plate 806 is pushed to be moved forward along rectilinear orbit 805, is positioned
Slide plate 806 drives pedestal 1 to be moved on first slot unit, and then the piston rod of cylinder 3 16 is retracted, and unclamps pedestal 1；It connects
It, the piston rod stretching of first compression cylinder 702 pushes down on briquetting 703, and briquetting 703 is pressed downward fixed block 704 and locating clip
Have, the second raised item 706 correspondence on positioning fixture is pressed in the pole slot 108 of pedestal 1, and positioning pin 708 stretches into corresponding positioning
In hole 107, agree with positioning fixture and pedestal 1, pedestal 1 is prevented to be subjected to displacement；
2) while pedestal 1 positions, the cylinder 6 142 in screw feed mechanism 12 pushes horizontal slide plate 124 along dampening
The direction level of smooth rail 123 slides into the top of screw changement 11；Cylinder 5 120 pushes vertical slide plate 122 along perpendicular
The direction of straight sliding rail 121 moves down, until the second dop of the second screw collet 128 on screw feed mechanism 12 and lower section
Screw changement 11 on collet framed bent 117 on screwing through hole 118 correspond；Then, in screw feed mechanism 12
Cylinder 7 126 start, will from screw feeding mechanism 5 enter ejector sleeve 127 screw pass sequentially through the second screw collet 128, folder
Head framed bent 117 is pushed into corresponding first screw collet 113；
3) screw is sent into after the first screw collet 113 in cylinder 5 120 and the band of cylinder 6 142 by screw feed mechanism 12
Dynamic lower reset；At this point, the direction of the first dop 110 on the first screw collet 113 is directed downwardly, in the first dop 110
The opening direction of screw be also directed downwardly；Then, multiple reversing motors on screw changement 11 start to rotate, and make correspondence
Reversing motor transmission shaft on the first screw collet 113 direction occur 180 ° overturning, the side of the first dop 110 after overturning
To upward, the nail mouth direction of the screw in the first dop 110 is also upward；Then, the spindle motor in 2 10 outside of supporting rack
Start to rotate, screw changement 11 is driven to be moved to the lower section of positioning plate 803 along 6 direction of leading screw；On workbench 3
The piston rod of cylinder 8 141 fixed frame in lock screw mechanism 13 is pushed to be moved to the lower section of first slot unit；
4) when pedestal 1 is located at the surface of first slot unit, lock screw mechanism 13 is located at first slot unit
Underface when, the cylinder 9 136 below first slot unit pushes screwdriver bit fixture 13 along 137 direction of slideway toward moving up
It is dynamic, screwdriver bit 139 is made to be stretched into the first screw collet 113 from the nail mouth 118 on collet framed bent 117, and with the first screw collet 113
In screw screw terminal contradict, then push screw worn from the slot 804 on the first dop 110, positioning plate 803 successively
Go out, finally enter corresponding on pedestal 1 lock in hole；Then, electric screwdriver 135 starts, and screwdriver bit 139 is driven to rotate, and completes corresponding lock
Attached hole locks；
5) it after the completion of first slot unit locks, participates in the screwdriver bit locked 139 and is returned back under the drive of cylinder 9 136
The underface of first slot unit；The piston rod of first compression cylinder 702 is retracted, affiliated briquetting 703, fixed block 704
Initial position is returned to positioning fixture reset；The piston rod of cylinder 4 17 pushes positioning slide plate 806 to continue to move along simultaneously, makes
Pedestal 1 is moved on second slot unit；Meanwhile the piston rod of cylinder 8 141 pushes 13 to the second slots of lock screw mechanism
The lower section of hole unit；Then, the cylinder 9 136 below second slot unit pushes screwdriver bit fixture 13 along 137 direction of slideway
Up move, screwdriver bit 139 made to be stretched into the first screw collet 113 from the nail mouth 118 on collet framed bent 117, and with the first screw
The screw terminal of screw in collet 113 contradicts, and then pushes screw successively from the slot on the first dop 110, positioning plate 803
It is pierced by 804, finally enters corresponding on pedestal 1 lock in hole；Then, electric screwdriver 135 starts, 130 band of rotary shaft of electric screwdriver 135
Dynamic screwdriver bit 139 rotates, and completes the part and locks locking for hole；
Above procedure is repeated, until the hole that locks for needing to lock on pedestal 1 is all locked by screw.
