Abstract
The utility model relates to a chief axle cutter seat structure of an automatic cutting machine, consisting of a body and a pressure cover. A cutter hole is equipped for putting into the cutter on the axle direction of the body, the pressure cover group is equipped outside the body, and turning the pressure cover can force the body to clamp the cutter. Therein at least one continuity twist rifle is equipped inside the inner wall of the cutter hole, and extends along the cutter hole axle. When the cutter group is equipped inside the cutter hole, at least one continuity twist rifle is contacted with the cutter surface in twist form, and provides an operating force to clamp the cutter smoothly and equably. Also one end of the rifle does not pass through the end face of the cutter hole, and can prevent the cuttings coming into the blade. In addition a protective ring is equipped between the body and the pressure cover, and the protecting ring has an end covers outside the pressure cover surface, to prevent the cutting affects the rotating of the pressure cover.
Description
[technical field]
The utility model is about a kind of tool rest structure, refers in particular to the tool rest structure that supplies to be assembled in the main shaft of an automatic cutter and supply cutter plant installation.
[background technology]
Automatically cutter comprises comprehensive machine, automatic lathe, automatic milling machine etc.The main shaft of general automatic cutting processing machine can provide high speed rotating, and therefore group is located at the tool rest of this main shaft one end, and the cutter on the tool rest, can rotate by synchronous high-speed, so that working substance is carried out machining.
See also Fig. 1 to shown in Figure 3, one tool rest (10) comprises a body (12), this body one end formation one pushes away pulls out end (14) for (not shown) in the main shaft of inserting cutting processing machine, and the other end is defined as tool bore end (16) and axially forms a tool bore (18) and can insert for a cutter (not shown).
Another packing cover (20) is nested with the outer surface at the tool bore end (16) of this body (12), and it is relative that this packing cover (20) inner face and tool bore end (16) outer surface have a tapering, and be provided with plural rolling member (22) between this packing cover (20) and this tool bore end (16).So, rotating this packing cover (20) can make this tool bore end (16) form the gathering packing because of the tapering relative motion.
Specifically, this tool bore (18) internal face is more established plural conduit (30) along axial system, and mat plural number conduit (30) can make this tool bore end (16) have more the elastic deformability, can contact the effect that improves clamp-on tool with cutter because of each conduit (30).
Yet, in case when the depth of each conduit (30), length were uneven, the active force of clamping cutter also can be uneven.Under tool rest (10) and cutter high speed rotating, this cutter is easy to generate and rocks.
In addition, an end of each conduit (30) all makes the end face of this tool bore end (16) form breach, and the cutting swarf that makes processing be produced enters and is detained in this tool bore (18), influences the symmetry of this tool bore (18) internal face, cutter can't be stabilized clamp.
In addition, between these packing cover (20) one ends and tool bore end (16) are held, be not formed with a spacing (32), cause cutting swarf residual easily, influence the turn of this packing cover (20).
The conduit of the tool rest structure that prior art disclosed must careful processing so that each conduit depth, length are identical, cause processing to be difficult for; Cutting swarf enters the effect that influences clamp-on tool in the tool bore from each conduit end easily; And cutting swarf can remain in this tool rest surface and influence this packing and overlap shortcomings such as rotation,
[novel content]
Main purpose of the present utility model is to provide a kind of main shaft tool rest structure of automatic cutter, to solve aforementioned every shortcoming.
The utility model is to realize like this, it comprises a body and a packing cover, wherein this body shaft is inserted for a cutter to offering a tool bore, this is external and this packing cover group is established, and rotating this packing cover can force this body to grip this cutter, this tool bore internal face system is established at least one helical form rifling, and this set of knives is located in this tool bore, and this at least one rifling contacts with this tool surface with spiral round form; It more comprises a retaining ring, and this retaining ring group is located between this body and this packing cover, and this retaining ring one end is nested with at this packing cover outer surface.
The main shaft tool rest structure of automatic cutter provided by the utility model, its internal face system at tool bore is established spiral helicine rifling, so cutter is inserted in this tool bore, then this rifling contacts with cutter in spiral round mode, therefore can provide more firm clamping effect to cutter, and rifling is that each conduit that the continuity structure can solve prior art causes the uneven shortcoming of each conduit because of independently adding trade union.In addition, an end of rifling can not form opening at the end face of tool bore end, so cutting swarf can not enter in this tool bore.
The retaining ring of the utility model can seal prior art and disclose the spacing that is positioned between this packing cover and tool bore end end, makes cutting swarf can not influence the rotation of this packing cover.

[specific embodiment]
See also Fig. 4 to shown in Figure 7, a tool rest (40) is the combination that comprises a body (50) and a packing cover (60).Wherein an end of this body (50) forms to push away and pulls out end (52) for inserting in the main shaft of cutting processing machine, and the other end forms tool bore end (54) and axially has tool bore (56).Internal face system that it should be noted that this tool bore (56) is established at least one rifling (58).This rifling (58) is the continuity spiral structure, and extending axially along tool bore (56).An end of this rifling (58) does not appear the end face (55) of this tool bore end (54) again.
This packing cover (60) is set in this tool bore end (54), and is equipped with plural rolling member (70) between this packing cover (60) and this tool bore end (54).This packing cover (60) but mat should plural number rolling member (70) and is easier to rotate relative to this tool bore end (54).This packing cover (60) all has tapering with tool bore end (54), makes its displacement so rotate this packing cover (60), then this tool bore end (54) is formed the packing effect.
Be to insert in this tool bore (56) and this tool bore end (54) when bringing together with this cutter of clamping with a cutter (not shown), this rifling (58) can touch state to axial formation circle solderless wrapped connection that should cutter, so, this cutter shaft can make this cutter obtain stable and uniform clamping action power to all contacting with this rifling (58) everywhere.
In addition, because these rifling (58) one ends do not appear the end face (55) of this tool bore end (54), so cutting process, cutting swarf can not enter this tool bore (56) inside from the end face (55) of this tool bore end (54), have the effect of even clamping cutter so can guarantee this tool bore (56).
See also Fig. 8, shown in Figure 9, the utility model more can set a retaining ring (80).This retaining ring (80) is that group is located between tool bore end (54) end and this packing cover (60) of this body (50), and these retaining ring (80) one ends are nested with at this packing cover (60) outer surface, so this retaining ring (60) can seal the spacing between this this packing cover (60) and tool bore end (54) end, during machining, cutting swarf can not enter between this packing cover (60) and tool bore end (54) end, so can not influence the rotation of this packing cover (60).
