Abstract

The utility model discloses a composite groove molding milling cutter with rotatable machine-clamp, which is composed of a tool body 1, a tool seat 2, a tool chip 3, a screw 4 and a club screw 5. A set of tool seats 2 are circumferentially arranged around the tool body 1, around which is provided with a tool seat grooves, the tool seat positioned by the bottom surface and the both sides in the tool seat groove is fixed in the tool seat grooves by the screw 4. One or a plurality of tool chip grooves is arranged on every single tool seat within the same set of tool seats, the position of the tool chip groove varies with different tool seats 2, the tool chips are vertically positioned in the tool chip grooves and fixed by the club screw 5. Groove molding is formed by overlap cutting of tool chips with different positions in a same set. The utility model has the advantages of that: vertical installation of tool chips increases the wear resistance of the tool chips meanwhile ensures the processing accuracy, the tool chip is positioned on the tool seat, so the tool body is protected from tool clashing which may break the tool chip and the tool seat, thereby increasing the use ratio of the tool body.

Description

Machine clip variable-position groove profile built-up milling cutter

Technical field

The utility model relates to a kind of milling cutter, particularly machine clip variable-position groove profile built-up milling cutter.

Technical background

At present, processing steel pipe soldering opening milling cutter roughly has following 2 kinds: clip type paperback (paperback is meant that big of blade the is rake face) bevel cutter that (1) is commonly used, it is directly the method for blade with the machine folder to be clamped on the cutterhead, and this class milling cutter shortcoming is that blade abrasion is fast, and precision and stock-removing efficiency are low; (2) blade is upright is contained on the cutter hub, directly is fixed on the cutter hub with screw, and the shortcoming of this milling cutter is that cutter hub damages easily when blade is forged a knife, thereby has reduced the utilization rate of cutter hub.

Summary of the invention

The purpose of this utility model promptly is to overcome the shortcoming of prior art, provides a kind of precision to keep, the machine clip variable-position groove profile built-up milling cutter that blade is wear-resisting, and its cutter hub utilization rate height, and easy to loading and unloading.

The purpose of this utility model is achieved through the following technical solutions: machine clip variable-position groove profile built-up milling cutter is made up of cutter hub, tool rest, blade, screw and plum blossom screw, tool rest is arranged on the circumference of cutter hub in groups, the circumference of cutter hub is provided with the tool rest groove, tool rest is located by bottom surface and two sides in the tool rest groove, and is screwed in the tool rest groove; In same group of tool rest: be provided with one or more insert grooves on each tool rest, the insert groove position difference of establishing on the different tool rests, upright being contained in the insert groove of blade fixed with the plum blossom screw; The blade of middle diverse location overlaps mutually and cuts the groove profile on the same group.

By top narration as can be seen, the utlity model has following advantage: the upright dress of blade makes blade quite wear-resisting; Guaranteed machining accuracy when blade is wear-resisting; Because blade is mounted on the tool rest, thus when blade is forged a knife, damage can not hurt cutter hub with regard to just blade and tool rest, improved the utilization rate of cutter hub.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described: shown in Fig. 2, Fig. 3 a, Fig. 3 b, Fig. 3 c, Fig. 3 d, Fig. 3 e, a kind of machine clip variable-position groove profile built-up milling cutter, it is made up of cutter hub 1, tool rest 2, blade 3, screw 4 and plum blossom screw 5, tool rest 2 is arranged on the circumference of cutter hub 1 in groups, the circumference of cutter hub 1 is provided with the tool rest groove, tool rest is located by bottom surface and two sides in the tool rest groove, and is fixed in the tool rest groove with screw 4; In same group of tool rest, each tool rest is provided with one or more insert grooves 7, the insert groove 7 position differences that different tool rests 2 are established, and upright being contained in the insert groove of blade fixed with plum blossom screw 5, and blade 3 upright dresses are meant that big of blade is the back knife face; The blade of middle diverse location overlaps mutually and cuts the groove profile on the same group; In every group of tool rest the number of tool rest 2 with put in order can be identical also can be inequality.

Shown in Fig. 1 a, Fig. 1 b, every group of tool rest group comprised three tool rests 2, the insert groove 7 that all is provided with diverse location on each tool rest can overlap mutually when making blade 3 be positioned on wherein and cut steel pipe groove forming surface 6, with the plum blossom screw blade 3 is fixed in the insert groove again.
