Threaded blind hole is opened to spout bottom and handle of a knife bottom looks parallel and level, handle of a knife bottom center, and handle of a knife bottom threaded connection has a circular baffle, circular baffle top center be equipped with with screw thread blind hole looks fit bolt, the diameter of circular baffle equals with sword handle diameter and its the central axis coincides mutually. End milling cutter can not skid in machining center's chuck at during operation, its handle of a knife, ensured end milling cutter's machining precision, greatly reduced the disability rate of work piece.

Description

Slotting cutter

Technical field

This utility model belongs to cutting tool technical field, especially relates to a kind of slotting cutter.

Background technology

Slotting cutter has the peripheral edge being formed from peripheral part and the cutter head of the shear blade composition being formed at front end and handle of a knife.Machining center slotting cutter uses alligator clamp to overlap installation way mostly, is in cantilever position during use.Due to the restriction of machining center clamp, most handle of a knife is cylindrical, in Milling Processes, owing to slotting cutter is acted on by cutting force, there may come a time when that the phenomenon that slotting cutter skids in cutter holder occurs, even result in slotting cutter and drop completely, cause the phenomenon that workpiece is scrapped.

Utility model content

In place of the purpose of this utility model is intended to solve the deficiencies in the prior art, and provide a kind of slotting cutter being prevented effectively from skidding, reduce the scrappage of workpiece.

The purpose of this utility model is solved by following technical proposal:

A kind of slotting cutter, including cutter head and handle of a knife, it is characterised in that: described handle side walls is prolonged and is axially had chute, on chute, sliding connects journal stirrup, having tapped through hole on described journal stirrup, tapped through hole central axis is paralleled with handle of a knife central axis, also includes the screw matched with tapped through hole；

Described chute bottom and handle of a knife bottom flush, handle of a knife bottom centre has tapped blind hole, handle of a knife bottom thread connects has circular baffle plate, described circular baffle plate top center to be provided with the bolt that matches with tapped blind hole, and the diameter of circular baffle plate is equal with shank diameter and its center axis coincides.

The bar number of chute described in the utility model is 1 and more than 1, and number and the chute bar number of described journal stirrup are equal.

Compared to the prior art this utility model has the characteristics that and beneficial effect:

1, handle side walls sliding connects journal stirrup, is fixed with slotting cutter machining center clamp by handle of a knife by journal stirrup with screw, is prevented effectively from slotting cutter and skids in fixture, reduces the scrappage of workpiece.

2, the circular baffle plate arranged bottom handle of a knife can be prevented effectively from slotting cutter idle time, and journal stirrup recalls in chute, when journal stirrup sustains damage, it is possible to by lower for circular baffle plate dismounting and be replaced.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further details.

A kind of slotting cutter as shown in Figure 1, including cutter head 1 and handle of a knife 2, described handle of a knife 2 sidewall prolongs and axially has chute 3, on chute 3, sliding connects journal stirrup 4, tapped through hole 5 is had on described journal stirrup 4, tapped through hole 5 central axis is paralleled with handle of a knife 2 central axis, also includes the screw 6 matched with tapped through hole 5.

As shown in Figure 4, when slotting cutter is operated, in first guaranteeing chute 3, it is provided with journal stirrup 4, the handle of a knife 2 being provided with journal stirrup 4 is placed in the chuck of machining center, with chuck, handle of a knife is clamped.Offering the screwed hole matched with tapped through hole 5 on chuck, screw 6 is threaded into through hole 5 and screwed hole, fixed with chuck by journal stirrup 4, the handle of a knife 2 that can be prevented effectively from slotting cutter skids in fixture.

As shown in Figure 2 and Figure 3, described chute 3 bottom and handle of a knife 2 bottom flush, handle of a knife 2 bottom centre has tapped blind hole 7, handle of a knife 2 bottom thread connects circular baffle plate 8, described circular baffle plate 8 top center is provided with the bolt 9 that matches with tapped blind hole 7, and the diameter of circular baffle plate 8 coincides with handle of a knife 2 equal diameters and its center axis.The circular baffle plate 8 arranged bottom handle of a knife 2 can be prevented effectively from slotting cutter when not working, and journal stirrup 4 recalls in chute 3.And when journal stirrup 4 sustains damage, it is possible to circular baffle plate 8 is dismantled down and is replaced, it is ensured that journal stirrup 4 effectively works.

The bar number of chute 3 described in the utility model is 1 and more than 1, and number and 3 numbers of chute of described journal stirrup 4 are equal.The journal stirrup 4 of different number can be set according to demand, while ensureing the intensity of handle of a knife 2, be prevented effectively from handle of a knife 2 and skid in chuck.

Operationally, its handle of a knife 2 will not skid in the chuck of the work in-process heart slotting cutter described in the utility model, it is ensured that the machining accuracy of slotting cutter, greatly reduces the scrappage of workpiece.

Specific embodiment described herein is only to this utility model spirit explanation for example.Described specific embodiment can be made various amendment or supplements or use similar mode to substitute by this utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
