Abstract

The utility model provides a tip which comprises a tip core and a tip seat. The tip seat is detachably connected with one end of the tip core. Compared with the prior art, the tip has the advantages that due to the fact that the tip comprises the tip core and the tip seat which are detachably connected, when the tip core is damaged, the whole tip does not need to be replaced, only the tip core needs to be replaced, a proper tip core can be used for operation according to the needs for machining different workpieces during a using process, production cost is lowered, the length of a small section close to the tip head portion of the tip core is at least 50mm, and the cross section area of the small section is not larger than 3/5 of the cross section area of a large section, so that during machining, when the outer diameters of the workpieces are small or machining depth is high, a milling cutter and a grinding wheel have large space to avoid the tip and cannot touch the tip. Accordingly, the tip is protected from damage during a machining process, the machined workpieces cannot be affected, and machining accuracy is guaranteed.

Description

A kind of top

Technical field

The utility model relates to a kind of top.

Background technology

When coming card engaging workpiece to carry out milling or grinding with tradition is top, because the workpiece external diameter is less or working depth when darker, milling cutter and emery wheel usually touch top easily.So not only can damage toply, and can impact workpiece to be machined, machining accuracy is difficult to guarantee, has also increased production cost simultaneously; And traditional toply when top pointed nose is damaged, whole toply all can only be changed, caused waste, also increased cost.

The utility model content

The utility model proposes a kind of toply, solved deficiency of the prior art, improved the precision of processing, having ensured simultaneously can be not damaged in the top process using yet, and has reduced production cost.

The technical solution of the utility model is achieved in that a kind of top, comprises top core and the dead head that removably connects with the one end.

Further, described top core comprises pointed nose and trunk portion, and described trunk portion comprises heavy in section section and small bore section, and this small bore segment length is at least the pointed nose of 50mm and close top core.

Further, the cross-sectional area of described small bore section is not more than 3/5 of heavy in section section cross-sectional area.

Further, described dead head is Morse taper shank.

Further, have the groove that is complementary with top core on the end face of the end that described dead head is connected with top core, have the screw hole that inserts hold-down screw from the dead head outer surface on the side of this groove.

Further, described screw hole is 1-4.

Further, described screw hole is 1.

Compared with prior art, the beneficial effects of the utility model are: after adopting said structure, because top top core and the dead head that removably connects that comprise, when top core is damaged, need not change again whole top, only needing to change top core gets final product, and in the process of usefulness, also can operate according to the more suitably top core of needs replacing of processing different workpieces, reduced production cost; And because the small bore segment length of close top core pointed nose is at least 50mm, the cross-sectional area of small bore section is not more than 3/5 of heavy in section section cross-sectional area, adding man-hour, when less the or working depth of workpiece external diameter is darker, it is top that milling cutter and emery wheel have larger space to avoid, and can not touch top again.Can protect so top can be not damaged in process, and can not impact workpiece to be machined, machining accuracy is guaranteed, and has also reduced production cost simultaneously.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is one of them embodiment of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the top view of the utility model embodiment;

Fig. 2 is the side schematic view after the utility model embodiment assembling.

Among the figure: 1, top core; 11, pointed nose; 12, heavy in section section; 13, small bore section; 2, dead head; 3, screw hole; 4, screw.

The specific embodiment

The below is clearly and completely described the technical scheme in the utility model, and obviously, described embodiment only is several embodiment wherein of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

As depicted in figs. 1 and 2, a kind of top, comprise top core 1 and the dead head 2 that removably connects with the one end, described dead head 2 is Morse taper shank, described top core 1 comprises pointed nose 11 and trunk portion, described trunk portion comprises heavy in section section 12 and small bore section 13, these small bore section 13 length are at least the pointed nose 11 of 50mm and close top core 1, the cross-sectional area of described small bore section 13 is not more than 3/5 of heavy in section section 12 cross-sectional areas, have the groove that is complementary with top core 1 on the end face of the end that described dead head 2 is connected with top core 1, have the screw hole 3 that inserts hold-down screw 4 from dead head 2 outer surfaces on the side of this groove, described screw hole 3 is 1-4.

In the present embodiment, top core 1 is end face band point cylinder steel part, with milling machine along mill on one side its its cylindrical cross-section long-pending 2/5, milling length is 50mm, be that small bore section 13 length are 50mm, the cross-sectional area of small bore section 13 is 3/5 of heavy in section section 12 cross-sectional areas, and described screw hole 3 is 1, dead head 2 and top core 1 is tightened by screw 4 in when assembling and can carry out processing work.

Because small bore section 13 length near top core 1 pointed nose 11 are at least 50mm, the cross-sectional area of small bore section 13 is not more than 3/5 of heavy in section section 12 cross-sectional areas, adding man-hour, when the less or working depth of workpiece external diameter was darker, milling cutter and emery wheel can not touch top again.Can protect so top can be not damaged in process, and can not impact workpiece to be machined, machining accuracy is guaranteed, and has also reduced production cost simultaneously; And in the process of usefulness, also can operate according to the more suitably top core 1 of needs replacing of processing different workpieces.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
