The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
Referring to accompanying drawing 1,2, the utility model boring grab, comprises chuck body 7, clamping device and stopping means.
Described chuck body top is 90 ° of V-shaped grooves.In the middle of bottom, along central shaft vertical direction, there is locating slot 17.There is through hole 20 in centre along central axis direction.Outside have left T-slot 18, the right T-slot 19 parallel with through hole in both sides.
Described clamping device comprises pressing plate 5, support 4, carrier base 10.Pressing plate 5 is a leverage component.The bearing pin 16 of take on support 4 swings as fulcrum.Its rear end fills an eccentric wheel 3.On eccentric wheel 3, there is one handle 24.Insert in carrier base 10 at the screw rod position of support 4 lower ends.By adjusting nut 2 and locking nut 1 adjusting pole 4 height.Carrier base 10 is arranged in the left T-slot of chuck body 7 18 by fastening bolt 25 and fastening nut 22.
Described stopping means comprises the adjustment screw 14 on gag lever post 15, baffle plate 13 and baffle plate.Gag lever post 15 is arranged in the through hole 20 of chuck body 7.
During work, the locating slot 17 along central shaft vertical direction in the middle of the bottom of chuck body 7 matches with the T-slot of Drilling machines bench by positioning key.Outside the have T-slot parallel with through hole 20 in both sides of chuck body 7; Wherein, left T-slot 18 is for installation and the adjustment of clamping device, and right T-slot 19 is for installation and the adjustment of drill sleeve device, and centre is used for mounting limit device gag lever post 15 along the through hole of central axis direction, to the bore position of workpiece 11 is positioned.
During work, pressing plate 5 is a leverage component.The bearing pin 16 of take on support 4 swings as fulcrum.Its rear end fills an eccentric wheel 3.On eccentric wheel 3, there is one handle 24.Workpiece in chuck body 7V shape groove 11 can be clamped, insert in carrier base 10 at the screw rod position of support 4 lower ends.By adjusting nut 2 and locking nut 1 adjusting pole 4 height.Carrier base 10 is for mounting bracket 4 and connecting clamp body 7, and carrier base 10 is arranged in the left T-slot of chuck body 7 18 by fastening bolt 25 and fastening nut 22.Make carrier base 10 can horizontally slip to adjust along left T-slot 18 position of clamping point, also increased the joint stiffness of the carrier base 10 in clamping device with chuck body 7 simultaneously.
As further improvement, the front end of pressing plate 5 is also equipped with a loose piece 6, when workpiece 11 diameters are when too small, or during lower than the upper plane of the V-shaped groove of chuck body 7, loose piece 6 is pulled downwards to turn 90 degrees and erect downwards, can expand the gripping range of pressing plate 5.
