Abstract
The utility model relates to a three-core cutting tool used for mechanical processing. At present, a square cutter is utilized widely in mechanical processing for aligning the cutting tool through shims. The alignment of the cutting tool is not accurate and is troublesome, and a plurality of shims and cutting tool bodies are wasted. The three-core cutting tool of the utility model utilizes the rotation of a cutting tool bar in the arc chutes of the cutting tool bodies and a gland bush to align the cutting tool. The three-core cutting tool has simple structure, convenient use, accurate cutting tool alignment, rapidity, time saving, labor saving, cutting tool material saving and cutting tool shim saving.
Description
The Three-core cutting tool that the utility model relates to belongs to the new-type cutter in the machining.
For a long time, being still of extensively adopting in the machining (particularly turner) prolonged the carbide bit that seat gets off decades and is welded on the square knife bar, then knife bar is fixed by bolts on the cutter platform, utilizes edge bearing to finish the adjustment of cutter to workpiece centre.
By researching and analysing, this kind method has following several shortcoming:
1, the center is bothered
Cutter head is mainly finished by the edge bearing of adjusting pad under square knife bar workpiece centre.Because the situation of suitable edge bearing is selected in frequent appearance repeatedly for use during tool setting,, be difficult to grasp the accuracy of tool setting again so promptly wasted the plenty of time for no reason.
2, waste knife bar material
Cutter head only accounts for the minimum part of cutter hub, and knife bar really accounts for the overwhelming majority of cutter hub.Because the requirement of cutter intensity, this most of knife bar can not save again, thereby has wasted high-quality steel greatly.
3, cutter real work angle is difficult for grasping
The geometric angle of cutter is a grinding-shaping before upper slitter, and the another one-tenth in back is constant on the tightening tools platform, and the strictness of this cutting-tool angle to the grinding of tool geometry angle with when using is grasped, and has brought a lot of inconvenience.
4, waste a large amount of edge bearings
Point of a knife is mainly finished by edge bearing the height of workpiece centre, loses a large amount of edge bearings.
5, point of a knife is difficult for accurately workpiece centre
The variable thickness of edge bearing meets the size of required edge bearing surely fully, so often will add which floor edge bearing, even like this, also is difficult to grasp the thickness of required edge bearing, often causes point of a knife to be higher or lower than workpiece centre.
The purpose of this utility model is: provide a kind of simple in structure, easy to use, tool setting accurately, save time rapidly, laborsaving, the novel Three-core cutting tool of saving cutter hub material and edge bearing material.
The utility model is achieved in that traditional square knife bar is changed into cylinder shape knife rod, and the length of knife bar is about 1/2nd of former knife bar length.The cutter hub of novel knife bar is used for the part of clamping knife bar, has arc-shaped slot, and the deep-slotted chip breaker top should have an arc flute profile gland relatively, and fastening bolt is arranged.The diameter of column type knife bar and cutter hub arc-shaped slot and gland arc-shaped slot are consistent.The shank of cutter hub is cylindrical, and is carved with groove at shank near on the arc-shaped slot plane.What be used for clamping cutter hub shank is the circle hole shape elastic jacket of side opening one by one, and the body diameter of its circular hole and cutter hub shank equates.Utilize rotation and cutter hub the rotation chuck in of knife bar in cutter hub and gland deep-slotted chip breaker to finish tool setting work.
Because this kind method of work is to utilize knife bar and cutter hub to be rotatably assorted with the center of oneself separately, finish tool setting work, so saved a large amount of edge bearings and tool setting time, make tool setting more accurately, rapidly.
Because the rotation by knife bar and cutter hub, can change the position of cutting plane and major flank again, thus the several main angle of cutters such as change anterior angle, relief angle, cutting angle, and promptly the method by grinding just can not change cutting-tool angle.
Also because the contraction in length of knife bar is about 1/2nd of a former square knife bar, so saved a large amount of high-quality steel.
But the utility model Three-core cutting tool processing excircles, endoporus, plane, stage, screw thread, groove, cut-out etc.
The utility model Three-core cutting tool is exactly a knife bar with the deep-slotted chip breaker of cutter hub and gland is the center, rotatable 180 °.Cutter hub is rotatable 180 ° of center with the chuck.Cooperate by the rotation of prolonging these two axis, find the center of suitable cutter workpiece.
The concrete structure of utility model is provided by following enforcement series and accompanying drawing thereof.
Figure one is the installation diagram of knife bar, cutter hub chuck.Figure two is gland and bolts assemblies figure.Figure three is A-A section perspective views of figure one.Figure four is that the B of figure one is to view.
(1) cutter hub (2) chuck (5) knife bar among the figure one.(3) gland (4) bolt among the figure two.
Below in conjunction with accompanying drawing concrete device and the working condition thereof that the utility model proposes is described further.
This cutter is shown in figure one, elder generation packs knife bar (5) in the cutter hub (1) that has the semicircular arc groove, again bolt (4) is fixed in the screwed hole of cutter hub (1) gently together with gland (3) (as figure two), can rotate the knife bar (5) that is stuck in cutter hub (1) semicircular arc groove and gland (3) the semicircular arc groove gently with hand is as the criterion, knife bar (5) together with cutter hub (1) in the elastic jacket of packing into (2), the cutter platform of packing into, adjust cutter platform bolt, can rotate cutter hub (1) gently with hand and be as the criterion, begin tool setting work afterwards.The method of work is to match and finish by the rotation and the rotation of cylindrical shank in chuck (2) hole of cutter hub (1) of knife bar (5) in cutter hub (1) and gland (3) semicircular arc groove.After meeting required cutter height fully, with the locking of cutter platform bolt, then that the bolt on the cutter (4) is fastening, then this cutter is finished the tool setting task, starts working earlier.
Utilize said method, not only can adjust the centre-height of cutter, also can adjust the geometric angle of cutter workpiece.Shown in figure one, when knife bar (5) rotated in the semicircular arc groove of cutter hub (1) and gland (3), owing to the position, cutting plane changes, and the angle of the angle of wedge was changeless, and then the anterior angle relief angle changes.Equally, the cutting plane changes when cutter hub (1) rotates in chuck (2), causes the anterior angle relief angle to change, and utilizes the variation of this cutting-tool angle, can increase the intensity of point of a knife part, reduces the grinding number of times of cutter.
Claims (2)
1, a kind of Three-core cutting tool that need not use edge bearing, it is characterized in that: the shank of knife bar (5) is cylindrical, it is the semicircular arc groove that cutter hub (1) is used for the position of clamping knife bar (5), compressing the gland (3) of knife bar (5) and the contact portion of knife bar (5) is the semicircular arc groove, unclamp the center line that fastening bolt (4) knife bar (5) can prolong cutter hub (1) deep-slotted chip breaker and gland (3) deep-slotted chip breaker, rotate 180 °.
2, according to the said Three-core cutting tool of claim 1, the shank that is characterised in that cutter hub (1) is cylindrical, and is carved with groove, and chuck (2) is the elastic jacket of a side opening, unclamps cutter platform fastening bolt, and cutter hub (1) can rotate 180 ° in chuck (2).
