Specific embodiment
As depicted in figs. 1 and 2, the tongue piece of car puller hook includes head and tail portion, and head has 1 He of upper pin block being oppositely arranged
Draw-bore 3 is needed on lower pin block 2, upper pin block 1 and lower pin block 2, there are installation gap 4 between upper pin block 1 and lower pin block 2, is passed through
Inserted sheet on car puller hook is inserted into the installation gap 4, pin shaft is recycled to be sequentially connected pin block 1, inserted sheet and lower pin block 2, from
And tongue piece is installed on car puller hook.
As shown in Figure 3 and Figure 4, the present embodiment provides a kind of boring grab for car puller hook tongue piece hole, including pedestal 6,
Fixed frame 7, guide plate 8 and cylinder 9.Pedestal 6 is installed on drilling machine, and fixed frame 7 is welded on pedestal 6, and fixed frame 7, which is equipped with, to be used
In the limiting slot 10 for placing tongue piece, limiting slot 10 is horizontally disposed, and there are two connected open side 11, can pass through open side 11
Tongue piece is quickly put into limiting slot 10.Limiting slot 10 includes head limited wall 12 and tail portion limited wall 13, head limited wall 12
The rostral anterior of tongue piece can be abutted；Tail portion limited wall 13 can abut the tail portion of tongue piece, and specifically, there is a protrusion in the tail portion of tongue piece
Latch portion 5, tail portion limited wall 13 include transverse wall 14, longitudinal wall 15 and tapered wall 16, transverse wall 14, longitudinal wall 15 and tapered wall
16 be sequentially connected and formed with the matched lock buckling groove of latch portion 5, so that the tail portion of tongue piece is limited in lock buckling groove.
Guide plate 8 is welded on fixed frame 7, the interior pilot hole 17 being equipped with for starter of guide plate 8, and pilot hole 17
In the surface of pin hole 3 to be processed on tongue piece, drill bit may pass through pilot hole 17 to the head draw-bore 3 of tongue piece, make drilling more
Add accurate quick.
As shown in figure 4, cylinder 9 is installed on pedestal 6 by bolt, 9 output rods of cylinder towards the direction of fixed frame 7,
Cylinder 9 can drive output rod to resist the back head of tongue piece from direction of the outer side in open side 11 into limiting slot, and then to tongue piece
Apply clamping force.Through the above structure, this fixture presss from both sides the rostral anterior of tongue piece, back head and tail portion in all directions
Tight limit, ensure that the positioning accuracy and reliable clamping force to tongue piece.
As shown in figure 3, placing tongue piece in the matched supporting block 18 in gap 4 is equipped with and installed in limiting slot 10 on fixed frame 7
When, the upper pin block 1 of tongue piece and lower pin block 2 are horizontally stuck in the two sides up and down of supporting block 18, make supporting block 18 to upper pin block 1 into
Row reliably supports, and avoids causing upper 1 stress deformation of pin block and borehole accuracy to decline because upper pin block 1 is hanging when drilling
Problem.The cephalad direction that supporting block 18 can also limit tongue piece towards tongue piece is mobile, further improves the limit effect to tongue piece.

And it is connected to limiting slot 10.The hand of operator, which protrudes into feeding hand position slot 19, rapidly to carry out feeding under to tongue piece
Material, improves processing efficiency.
As shown in figure 4, the output rod of cylinder 9 is equipped with the force head 20 with inclined surface, the inclined surface of force head 20 can be resisted
The head of tongue piece, inclined surface apply pressure to tongue piece towards the direction of head limited wall 12 and the direction of tail portion limited wall 13 simultaneously,
It is clamped to tongue piece steadily in limiting slot 10, further ensures the limit reliability of tongue piece.
As shown in Figure 3 and Figure 4, clamping column 21 is equipped with by screw on pedestal 6, clamping column 21 is from the other side opposite with tongue piece
Abutting force head 20, avoids tongue piece from applying biggish reaction force and make to exert a force 20 skew of head or shaking to force head 20, protects
It has demonstrate,proved 20 pairs of tongue pieces of force head and has carried out reliable grip.
The course of work of this fixture are as follows: tongue piece is horizontally placed in limiting slot 10, the head of tongue piece is made to be located at head
The latch portion 5 of 12 one end of limited wall, tail portion is placed in lock buckling groove, and the upper pin block 1 of tongue piece and lower pin block 2 are stuck in supporting block
18 two sides up and down make supporting block 18 support upper pin block 1.Then start cylinder 9, the output rod of cylinder 9 stretches out, force head 20 from
The back head of tongue piece applies pressure to tongue piece, and tongue piece is clamped in limiting slot 10, and clamping column 21 is from force head 20 during this
The other side resist force head 20, avoid force head 20 skew or shake.Start drilling machine, drill bit is by leading on guide plate 8
To after hole 17, successively drill to upper pin block 1 and lower pin block 2.After drilling is completed, drill bit exits, and the output rod of cylinder 9 exits, from
Tongue piece is taken out at feeding hand position slot 19.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, although ginseng
The utility model is described in detail according to previous embodiment, it for those skilled in the art, still can be with
It modifies the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.It is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in practical
Within novel protection scope.
