As shown in Figures 2 to 4, boring grab provided in this embodiment can conveniently, the clamping of stable realization L shape chaining plate
Positioning, can effectively improve the accuracy of drilling.
The boring grab that this programme provides can be used for the Set and Positioning in L shape chaining twist drill hole, it is of course also possible to be used for
Set and Positioning in Workpiece boring similar with L shape chaining plate.
The boring grab that this programme provides includes the first positioning plate 4, and the second positioning plate 5 ships and resell on another market 6, support 7, the first pressure
Plate 8, the first lock nut 9, guide sleeve 10, draw bar 11, the second pressing plate 12, the second lock nut 13, positioning pin 14.
The boring grab that this programme provides includes in horizontally disposed first positioning plate 4, and first positioning plate 4 is used for
The support of L shape chaining plate short slab 1 positions, and 4 edge of the first positioning plate is provided with the second positioning plate 5 to intersect vertically, institute
The support that the second positioning plate 5 is stated for L shape chaining plate long slab 3 positions.
In the present solution, be provided on the first positioning plate 5 left and right separately arrange ship and resell on another market 6 with support 7, it is described ship and resell on another market 6 with
The support 7 is each perpendicular to first positioning plate 5, is provided with the first pressing plate 8 above ship and resell on another market 6 and the support 7, described
First pressing plate, 8 right end is hinged with the support 7, and 8 left end of the first pressing plate ships and resell on another market 6 with described by the first lock nut 9
Detachable connection, compression of first pressing plate 8 for L shape chaining plate short slab 1 are limited, are provided on first pressing plate 8
The perpendicular guide sleeve 10 with first positioning plate 5, the guide sleeve 10 are walked for peripheral hardware drilling rod.
Guide sleeve 10 guarantees to glance off during drilling rod feeding for playing guiding role to walking for drilling rod.
To further increase drilling efficiency, guide sleeve 10 can be arranged multiple simultaneously in this programme, then set simultaneously in the present embodiment attached drawing
2 are equipped with, in this way, the boring grab can carry out bore operation by 2 L shape chaining plates of clamping simultaneously.
Specifically, when the first lock nut 9 with ship and resell on another market 6 release when, the first pressing plate 8 can be that fulcrum is clockwise with support 7
Overturning, when overturning to a certain extent when, L shape chaining plate short slab 1 hole to be drilled, which can be then placed into, ships and resell on another market 6 with 7 the two of support
Between, at this point, again turning counterclockwise the first pressing plate 8 for fulcrum with support 7, the first pressing plate 8 will cover L shape chaining plate short slab 1
On, then the first lock nut 9 is tightened on and is shipped and resell on another market on 6, in this way, the first pressing plate 8 can compress L shape chaining plate short slab 1
On the first positioning plate 5.
In the present solution, the draw bar 11 perpendicular with second positioning plate 5 is provided on the second positioning plate 5, it is described to lead
Draw that be inserted with above bar 11 can be along the second pressing plate 12 that the draw bar 11 moves up and down, and second pressing plate 12 can be forwards, backwards
Direction inclination, compression of second pressing plate 12 for L shape chaining plate long slab 3 are limited, are provided with above second pressing plate 12
Second lock nut 13 and second lock nut 13 are set in 11 top of draw bar.
Specifically, when L shape chaining plate long slab 3 is put between the second positioning plate 5 and the second pressing plate 12, due to the second pressure
Plate 12 can be moved up and down in draw bar 11 and can be tilted forward and backward, therefore, when the second lock nut 13 screws down,
The distance between second pressing plate 12 and the second positioning plate 5 can be gradually reduced, meanwhile, the second pressing plate 12 can be automatically inclined when compression
Turn certain angle, the second pressing plate 12 can be more gradually sloped up to its lower surface and be bonded with the upper surface of L shape chaining plate long slab 3, when
