Abstract
The utility model discloses a cutter bar of a milling cutter. The cutter bar comprises a taper shank section and a clamping section of the milling cutter, wherein the cutter bar is provided with a sleeve barrel on a middle section between the taper shank section and the clamping section of the milling cutter, the middle section and the sleeve barrel are in key connection or threaded connection or interference fit, the outer surface of the sleeve barrel is the outer surface of a rotator, and a bus bar at the outer surface of the rotator is a straight line or a broken line and/or a curve. Because the cutter bar is provided with the replaceable sleeve barrel between the taper shank section of the cutter bar and the clamping section of the milling cutter of the cutter bar, sleeve barrels with different shapes and/or different sizes can be sleeved on a milling machine according to conditions when the milling machine is used for processing workpieces with different shapes or larger sizes. In this way, the utility model can be used for milling and processing workpieces with various shapes and various sizes under the condition that the same milling machine uses the same cutter bar.
Description
Technical field
The utility model relates to a kind of cutting tool, is specifically related to a kind of knife bar of milling cutter.
Background technology
The knife bar of milling machine all is to be made of taper handle of a knife section, straight handle section and milling cutter clamping section in the prior art.Because the knife bar of existing milling cutter is overall structure; when the workpiece of milling machine processing special shape or larger-size workpiece; usually can produce the problem of movement interference, both knife bar can bump with workpiece, and this problem especially can often take place when horizontal milling machine milling workpiece.Therefore, be necessary existing milling cutter lever structure is improved.
The utility model content
The purpose of this utility model is to overcome defective of the prior art, and a kind of milling cutter knife bar of novel structure is provided, and the outer shape of this milling cutter knife bar and size can random variation, to be applicable to the workpiece of processing special shape and large-size.
For achieving the above object, the technical solution adopted in the utility model is a kind of milling cutter knife bar, this knife bar includes taper shank section and milling cutter clamping section, it is characterized in that described knife bar is equipped with sleeve on the stage casing between taper shank section and the milling cutter clamping section, key is connected between described stage casing and the described sleeve, or be threaded, or interference fit, the outer surface of described sleeve is the outer surface of rotary body, the bus of described rotary body outer surface is straight line or broken line and/or curve.
Be easy to be connected in order to make knife bar and sleeve be convenient to processing, preferable technical scheme comprises that described key connection includes flat key or spline.
Be easy to be connected in order to make knife bar and sleeve be convenient to processing, preferable technical scheme comprises that also the hand of spiral of described its screw thread that is threaded is opposite with the direction of rotation of milling cutter.
In order to be applicable to the processing of special shape and large-size workpiece, preferable technical scheme can be that described straightway is the straight line that parallels with the axis of described knife bar.
In order to be applicable to the processing of special shape and large-size workpiece, preferable technical scheme also can be that described straightway is the straight line that constitutes certain angle with the axis of described knife bar.
In order to be applicable to the processing of special shape and large-size workpiece, preferable technical scheme can also be that described broken line is the broken line that constitutes groove and/or boss on the surface of described knife bar.
In order to be applicable to the processing of special shape and large-size workpiece, preferable technical scheme can be again that described curve is the arcs of recesses line or is the convex curve.
In order to be applicable to the processing of special shape and large-size workpiece, preferable technical scheme can be that described curve is an arbitrary curve again.
Be easy to be connected in order to make knife bar and sleeve be convenient to processing, preferable technical scheme comprises that also described knife bar is provided with thread segment at an end of milling cutter clamping section.
Be easy to be connected in order to make knife bar and sleeve be convenient to processing, preferable technical scheme comprises that again described sleeve is steel bushing or is plastic sleeve.
Advantage of the present utility model and beneficial effect are: because this knife bar is provided with removable sleeve between its taper shank section and milling cutter clamping section, therefore milling machine can according to circumstances overlap the sleeve of loading onto different profiles and/or different size when the workpiece of processing difformity or large-size.So just can use under the situation of same knife bar, the workpiece of all kinds of shapes and various sizes is carried out Milling Process at same milling machine.And, then need the kind of knife bar more if employing is carried out method for processing according to the situation of workpiece to be machined to knife bar, and time-consuming, effort that processing is got up, cost is also higher.And in the technical solution of the utility model, only need make a kind of knife bar, and its sleeve can be made multiple shape with moulding, so both easy to use, be convenient to processing and fabricating again, also can reduce the cost of knife bar greatly.
