The tip 9 of 6 one end of top plate is between two inclined-plane A4 of 8 other end of a side locking tabs 2 and another side locking tabs of splayed distribution,
For the other end of screw rod 12 to being equipped with slotted hole A5 between middle part, the middle part of the top plate 6 is equipped with slotted hole B7, top plate 6 it is oval
Hole B7 length is 12 slotted hole A5 of screw rod one point five again to the long circular shaft between twice, with 12 slotted hole A5 structure matching of screw rod
14 middle parts are through in the slotted hole B7 of top plate 6, and the both ends of the long circular shaft 14 are fixedly connected in the slotted hole A5 of screw rod 12, institute
14 outer rim of long circular shaft at the middle part being slidably connected in slot 16 in the middle part of top plate 6 is stated, the other end of top plate 6 is exposed in the another of screw rod 12
One end end face direction.
It is suitable for the application of the self-locking screw rod of blind hole implantation, including workpiece subscript orifice position, work in conjunction with described in attached drawing 1 to 11
Preparation that part is beaten before blind hole, the matched reaming bit of selection, reaming gets annular in the middle part of the blind hole of workpiece using reaming bit
Slot reaming, the implantation for clearing up blind hole and screw rod;
A, workpiece subscript orifice position;
According to design drawing in 19 subscript orifice position of workpiece, workpiece 19 is fixed on the sliding platen of drilling machine, keeps hole location corresponding
Drill bit;
B, workpiece beats blind hole;
Opening equipment punches drill bit at mark hole location, and hole depth must satisfy subsequent reaming and need to obtain blind hole 21;
C, matched reaming bit is selected;
Select reaming bit bearing 35 and drilling rod 28 diameter matched with the aperture of blind hole 21 or slightly carefully;
D, the preparation before reaming;
By in the clamping piece 24 of the clamping end insertion bench drill chuck 23 of reaming bit drilling rod 28, chuck 23 is screwed by clamping piece
24 fix the clamping end of drilling rod 28, then by the bearing of reaming bit 35, cylinder 34, connection sheet 32, link block 30 and drilling rod
28 one end end is along blind hole 21 is entered, and the outer ring of bearing 35 withstands on the close perimeter wall at 21 inner end bellmouth bottom 20 of blind hole at this time
On;
E, annular groove reaming is got in the middle part of the blind hole of workpiece using reaming bit;
The main shaft for starting drilling machine drives reaming bit rotation, makes to slide the workpiece on platen towards reaming bit direction by rolled round
Mobile, the outer ring of bearing 35 withstands on 21 inner end of blind hole at this time, and water pipe 25, the inner ring of bearing 35 and reaming is arranged on 21 top of blind hole
28 synchronous rotary of drilling rod of drill bit, the junction stress bending of the connection sheet 32 being squeezed at this time and link block 30, and meanwhile it is convex
Alloy face on bittiness 32 starts to carry out surrounding cutting in the middle part of to blind hole 21, and the synchronous cooling water 26 flowed out by water pipe 25 is fought each other
The cooling of hole process, the iron filings and water 27 of drill process outflow extand rearward to 28 middle part of drilling rod by the slot that 28 front end of drilling rod is arranged
The slot outflow, until getting satisfactory annular groove reaming 22 at the middle part of blind hole 21;Drilling machine power supply is closed, rolled round is passed through
Making to slide the movement of workpiece 19 on platen makes reaming bit exit blind hole 21;
F, blind hole is cleared up;
It is fulfiled assignment using giant to being rinsed in blind hole 21;
G, the implantation of screw rod;
Metal adhesive liquid is poured into the drying blind hole 21 with annular groove reaming 22, and a side locking tabs 2 and another side locking tabs 8 are pressed
It is pressed in the slot 16 of screw rod 12, blind hole 21 is inserted into using the other end of screw rod 12, when the other end end of screw rod 12 is close to blind hole
When 21 bottom hole 20, top plate 6 is just contacted with the bottom hole 20 of blind hole 21, and 9 liang of inclined-plane B18 of the tip of 6 one end of top plate are respectively to one at this time
The protrusion 1 of the inclined-plane A4 of side locking tabs 2 and another side locking tabs 8 application pressure, a side locking tabs 2 and another side locking tabs 8 is just in annular
In slot reaming, the implantation for obtaining screw rod 12 is solidified to metal adhesive liquid, and the external screw thread 11 of 12 outer end of screw rod can be with other works
