It shelves 1 bottom and is provided with jig mainboard 2,2 two sides of jig mainboard are fixed with push plate cylinder 3,3 piston-rod end of push plate cylinder
It is connected with the top surface of 4 two sides of push plate;2 bottom surface of jig mainboard is provided with multiple nut crawl needles 5, and nut grabs 5 end of needle
It tightens pushing cylinder 6 across push plate 4 and is socketed on the outside of nut crawl 5 end of needle, tighten 6 front end of pushing cylinder and be fixed on 4 bottom surface of push plate in end;
2 top surface of jig mainboard is provided with the first mounting plate 7, and ejector retainner plate cylinder 8,8 piston of ejector retainner plate cylinder are fixed on the first mounting plate 7
Bar end is fixed with ejector retainner plate 9, and 9 bottom of ejector retainner plate is provided with nut eject pin 10, and 10 end of nut eject pin passes through and controls
Has mobile 5 inside of insertion nut crawl needle of mainboard 2.
The jig mainboard 2 is additionally provided with the second mounting plate 11, and second mounting plate 11 is fixed with folder product cylinder 12,
12 piston-rod end of folder product cylinder is connected with folder production board 13, and folder 13 bottom of production board is provided with finger cylinder 14.
2 bottom surface of jig mainboard is provided with limited block 15, when for manipulator movement jig mainboard, limited block and mold
When being in contact, manipulator stops movement.
4 bottom surface of push plate is provided with positioning guide column 16, mutually positions for push plate and nut station and mold.
2 bottom surface of jig mainboard is provided with guide post 17, and the guide post 17 is inserted into 4 bottom surface of push plate and is provided with guide sleeve 18, uses
It is mutually positioned in jig mainboard with push plate.
Further include nut station 19, nut pilot pin 20, the nut positioning are provided on the nut station 19
Nut 21 is placed on needle 20.
The nut crawl needle 5 is arranged in two rows, and every row is provided with multiple nut crawl needles 5, each 5 end of nut crawl needle
End outside, which is socketed with, tightens pushing cylinder 6, and inside grabs needle 10 inserted with nut.
Embodiment 1:
The design forming jig is connected with manipulator when in use, by manipulator mounting rack, mechanical hand-motion molding
Jig moves between product component platform, nut station, processing mold, and product component is taken, nut is taken, nut is put for completion
The process set.
As shown in figure 4, multiple nut crawl needles are fixed on jig mainboard in two rows structure, tighten pushing cylinder and be fixed on
In push plate, nut eject pin is fixed on ejector retainner plate, and push plate cylinder is fixed on jig mainboard, make to tighten pushing cylinder complete ejection with
Fallback action, ejector retainner plate cylinder are fixed on jig mainboard, and nut eject pin is made to complete ejection and fallback action.
Multiple nuts are put into the nut pilot pin of nut station, nut station is horizontal positioned, and manipulator will be controlled
Have mainboard rotation to be inserted into nut station downward, realizes that precise positioning, limited block contact nut station by positioning guide column
When limit, nut is precisely directed into nut crawl needle, and nut is close to nut eject pin.At this point, manipulator, which issues, releases signal
Push plate cylinder is given, push plate cylinder makes push plate travel forward, and the tightening extruding nut after pushing cylinder travels forward being fixed in push plate is grabbed
Needle is taken, nut grabs the fixed simultaneously binding nut of needle, and jig mainboard exits nut station, and it is dynamic to complete forming jig crawl nut
Make.
Jig mainboard is rotated return by manipulator, and jig mainboard is inserted into mold, positioning guide column and mode are passed through
Precise positioning, when limited block contacts mode limit, nut has been directed into mould inner nut pilot pin, and manipulator issues back-off signal
Push plate cylinder is given, push plate cylinder drives push plate, makes to tighten pushing cylinder return, nut grabs needle and unclamps nut.Manipulator issues top again
Signal gives ejector retainner plate cylinder out, moves ejector retainner plate, and nut eject pin ejection, nut is pushed up to mould inner nut pilot pin bottom,
Multiple nuts are completed to be embedded to the movement of mold.
Jig mainboard is exited mold by manipulator, and jig mainboard completes multiple nut crawl burying forming movements.This jig
In nut grasping mechanism, nut can be securely fixed, when jig mainboard multi-direction translation, overturning when nut do not fall out, can
Cooperate vertical molding machine, Horizontal molding machine uses.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
