Can holes drilled through, blind hole, replace special tool, can expand, spot-facing, fraising or carry out the processing such as tapping.Workpiece is motionless in process,
It allows cutter to move, by center cutter alignment hole center, and cutter is made to rotate.
When being processed to workpiece on drilling machine, main shaft moves downward, and axial distance is increasingly longer, rigidly worse and worse,
Diameter, which is jumped, also gradually to be increased, and since drill bit is swung, drill bit is not sharp, drill bit back angle is big etc., that drill bits self problem is easy to cause hole wall is thick
The defects of rough, drilling expands, hole is in polygonal, and due to auger axis and work top out of plumb, workpiece is loosened or is fixed not
The reasons such as tight be easy to cause broken drill, bore position deflection, it is crooked the defects of.And during the hole processed on existing drilling machine is mostly
The hole of small size, cutter diameter is often smaller, and axial dimension is larger, be easy to cause the Form and position error in hole.For cylinder, pipe
The non-flat noodles workpiece such as class, spherical surface is drilled more difficult above it due to the skidding of drill bit.
Utility model content
The utility model for existing drilling machine bore non-flat noodles workpiece there are drill slipping, drilling is time-consuming and laborious, drilling essence
The deficiencies of spending low, drill bit frangibility, high workpiece scrappage proposes a kind of drilling machine auxiliary clamp, can promote drilling processing efficiency, carry
Borehole accuracy is risen, the loss of machining tool is reduced.
The technical solution of the utility model：A kind of drilling machine auxiliary clamp, it is characterised in that：The fixture is by pedestal, Zuo Jia
Pawl, right clamping jaw and positioning bolt are constituted, and the middle of the base is equipped with locating slot, and clamping jaw is equipped at left and right sides of the locating slot
The side wall of placing groove, the clamping jaw placing groove is equipped with location hole, and the left clamping jaw and the setting of right clamping jaw are placed in the clamping jaw
In slot, the left and right clamping jaw is made of clamping face and mobile bar, and the medial surface of the clamping face is arcwall face, the movement
Bar, which moves up and down, to be acted in clamping jaw placing groove, and is fixed in clamping jaw placing groove by the positioning bolt in location hole.
The locating slot is semicircle locating slot.
The mobile bar is the mobile bar of rectangular in cross-section, and the width of mobile bar is the 1/3 of base width, the height of mobile bar
Degree is slightly above the groove depth of clamping jaw placing groove.
The medial surface of the clamping face is arcwall face identical with positioning groove radius, and the arc length of clamping face is locating slot arc length
1/2.
Quantity of the clamping jaw placing groove per side positioning hole is 2, and the hole heart of location hole is in clamping jaw and places groove height side
To centre position, all location holes are all in the same horizontal plane.
The beneficial effects of the utility model are：The utility model proposes a kind of drilling machine auxiliary clamp, structure novel, work
Clear principle is made of pedestal, clamping jaw, positioning bolt in structure, and locating slot and clamping jaw placing groove are arranged on pedestal, and clamping jaw is placed
Left and right clamping jaw is set in slot, positioning is clamped by locating slot and left and right clamping jaw collective effect to machined part, passes through positioning
Bolt realizes that the utility model, can be effectively to the axis of different-diameter compared with traditional fixture to the clamping and positioning of left and right clamping jaw
Class part is clamped drilling, the phenomenon that effectively preventing drill slipping, and drilling is time saving and energy saving, borehole accuracy is high, effective protection
Drill bit, reduces the loss of machining tool, reduces workpiece scrappage, further improve drilling processing efficiency.
