Abstract
The utility model belongs to machining cutter field, in particular to multipurpose boring cutter pole solves the unable problem of processing blind hole and poor stability of current boring cutter pole. Multipurpose boring cutter pole includes cutter bar body, and the blade mounting hole has been seted up to cutter bar body's one end, is equipped with the core bar in the core bar mounting hole of cutter bar body inside to pass through clamp bolt. The utility model discloses a multipurpose boring cutter pole one end includes the blade mounting hole, and the boring cutter piece can be followed the direction of perpendicular to cutter bar body axis and installed in the blade mounting hole to the processing of adaptation blind hole, fix the boring cutter piece through the core bar, structural stability is strong, in addition, multiple boring cutter piece can also be installed to the blade mounting hole to adapt to the processing in multiple hole.
Description
Technical field
The utility model belongs to machining tool field, particularly a kind of Multipurpose boring cutter bar.
Background technology
At present, boring cutter is roughly divided into Split type boring cutter bar and monoblock type boring cutter bar.But Split type boring cutter bar is that bolt withstands blade on front side of knife bar, and in process, bolt head easily withstands blind via bottom, cannot be worked into hole depth size.And the raw material of monoblock type boring cutter bar are carbide cutter tool, such as, during the part of or dark blind hole high in workhardness, easily there is cutter phenomenon of shaking in carbide alloy boring cutter, then directly collapses cutter time serious, and collapse cutter fragment and not easily take out in part, causes whole part rejection.
Utility model content
The utility model provides a kind of Multipurpose boring cutter bar, cannot processing blind hole and the problem of poor stability to solve existing boring cutter bar.
The technical solution of the utility model:
A kind of Multipurpose boring cutter bar, comprising:
Cutter bar body, one end of described cutter bar body offers blade mounting holes, and the axes normal of described blade mounting holes is in the axis of described cutter bar body;
Core bar installing hole, is positioned at the inside of described cutter bar body, extends, and be communicated with described blade mounting holes from the end face of the described cutter bar body other end along the axis direction of described cutter bar body;
Core bar, is arranged in described core bar installing hole;
Hold-down bolt, is fixedly installed in the described core bar installing hole of the end of the described cutter bar body other end, and contacts with described core bar one end end face.
Alternatively, the described core bar installing hole place being provided with described hold-down bolt offers the internal thread mated with described hold-down bolt.
Alternatively, described cutter bar body is coniform, and the diameter arranging the cutter bar body at described blade mounting holes place is less than the diameter of the cutter bar body arranging described hold-down bolt place.
The beneficial effects of the utility model:
Multipurpose boring cutter bar one end of the present utility model comprises blade mounting holes, and boring blade can be arranged on blade mounting holes from the direction perpendicular to cutter bar body axis, to adapt to the processing of blind hole; Be fixed by boring blade by core bar, structural stability is strong; In addition, blade mounting holes can also install multiple boring blade, to adapt to the processing of multiple hole.

Detailed description of the invention
Below in conjunction with accompanying drawing, the paddle molding mould involved by the utility model is described in further details.
As shown in Figures 1 to 5, a kind of Multipurpose boring cutter bar of the present utility model, comprises cutter bar body 1.
Cutter bar body 1 can be multiple applicable shape, but it has at least a part of outer ring surface to be match with the tool rest 6 of lathe, can be arranged on tool rest 6.In the present embodiment, cutter bar body 1 entirety is in coniform, and wherein, the diameter arranging the cutter bar body 1 at blade mounting holes 2 place (left end in Fig. 1) is less than the diameter of the cutter bar body 1 arranging hold-down bolt 3 place (right-hand member in Fig. 1).
One end (left end in Fig. 1) of cutter bar body 1 offers blade mounting holes 2, and the axes normal of blade mounting holes 2 is in the axis of cutter bar body 1.Blade mounting holes 2 is generally square, matches with the installation end of boring blade 5, and boring blade 5 is loaded in blade mounting holes 2 by installation end, is slidably matched with face each in blade mounting holes 2.
Core bar installing hole, is positioned at the inside of cutter bar body 1, extends, and be communicated with blade mounting holes 2 from the end face of cutter bar body 1 other end (right-hand member Fig. 1) along the axis direction of cutter bar body 1.Be provided with core bar 4 in core bar installing hole, the length of core bar 4 is less than the length of core bar installing hole.
The core bar installing hole place of cutter bar body 1 right-hand member offers internal thread, and internal thread place is provided with hold-down bolt 3, is greater than or equal to the length of core bar installing hole after the length of hold-down bolt 3 and core bar 4.By hold-down bolt 3 contact with core bar 4 end face, by core bar 4 fixed press in core bar installing hole, thus by core bar 4 by boring blade 5 fixed press is blade mounting holes 2 in, last overall loading tool rest 6.
Multipurpose boring cutter bar one end of the present utility model comprises blade mounting holes 2, and boring blade 5 can be arranged on blade mounting holes 2, to adapt to the processing of blind hole from the direction perpendicular to cutter bar body 1 axis.Be fixed by boring blade 5 by core bar 4, structural stability is strong.Blade mounting holes 2 can also install multiple boring blade 5, to adapt to the processing of multiple hole.In addition, Multipurpose boring cutter bar of the present utility model dismounting easily, blade fast changeable and can various blind hole be processed.
As shown in Figure 5, in process, axial length (direction perpendicular to cutter bar body 1 axis) also by regulating hold-down bolt 3 to carry out regulating boring cutter sheet 5, thus control the processing radial depth of boring blade 5, can not only processing deep blind-hole, can also make the stepped hole on complex parts on a chassis bed once clamping complete, avoid repeated removal, thus the axiality improved between each hole and precision.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the original prerequisite of the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
