Abstract

The utility model discloses a clamp bit, which comprises a knife bar and a long rod shaped blade, wherein, an elongated slot is arranged on the bar, the cutting sides of the blade are all sharpened into cutting angles, a chip-breaker groove is also sharpened on, the knife blade capable of sliding is inserted into the elongated slot, the section of the elongated slot is same as that of the knife blade. Because of the formed cutting sides, when the cutting part is local abraded or damaged, the knife blade is only needed to eject forward along the elongated slot in a suitable length and re-sharpen to the former cutting angle for reusing. Thus, the sharpening becomes simple and convenient. In addition, the long blade enables to sharpen for multi times, therefore having the long usage time and the elegant duality for teaching.

Description

A kind of mechanically-clamped turning tool

Technical field

The utility model relates to a kind of lathe tool that is used for cutting workpiece on the lathe, particularly a kind of mechanically-clamped turning tool.

Background technology

Mechanically-clamped turning tool, blade is fixed on the knife bar by the mode of mechanical clamping, without high-temperature soldering, has avoided the various defectives that produce because of welding, and its blade durability is good, thereby has obtained using widely.Existing mechanically-clamped turning tool, blade are generally less, the sharpening inconvenience, and only can the sharpening minority just need several times to change, its blade exchange is frequent, utilization rate is low.For the beginner, blade damaged easily when it used lathe tool especially, and it is very inconvenient often to need to change.

Summary of the invention

The utility model purpose is to provide a kind of sharpening simple, convenient, and blade utilization rate height, service time are long, and the mechanically-clamped turning tool of sharpening repeatedly.

Mechanically-clamped turning tool described in the utility model includes knife bar and blade, on its knife bar elongated slot is arranged, blade is elongated rod shape, and the equal sharpening of truncated sides becomes cutting angle, and sharpening has chip-breaker, blade inserts in the elongated slot slidably, and the cross sectional shape of elongated slot is consistent with the cross sectional shape of blade.

Blade is elongated rod shape, inserts in movably in the elongated slot, and after blade cut was was partly worn and torn or damaged, because therefore all sharpening shapings of blade cut side only need lathe tool is released suitable length forward along elongated slot, polishing into original angle once more can normally use.Its sharpening is simple, convenient.Blade is grown its repeatedly sharpening simultaneously, and service time is long, utilization rate height, good endurance.Blade is long simultaneously, and sharpening is fit to teaching and uses very much repeatedly.

The specific embodiment

Embodiment 1, as Fig. 1, Fig. 2, Fig. 3, a kind of lathe tool, knife bar 1 and blade 2 are arranged, on its knife bar 1 elongated slot 3 is arranged, blade 2 is elongated rod shape, the equal sharpening of truncated sides becomes cutting angle, and sharpening has chip-breaker 4, and blade 2 inserts in the elongated slot 3 slidably, and the cross sectional shape of elongated slot 3 is identical with the cross sectional shape of blade 2.

Blade 2 is elongated rod shape, insert in movably in the elongated slot 3, after the cutting tip wearing and tearing or damage of blade 2, because the cutting angle of blade cut side and chip-breaker 4 be sharpening shaping all, therefore only need blade is released suitable length forward along elongated slot 3, polishing into original angle once more can normally use.Its sharpening is simple, convenient.Blade 2 is grown its repeatedly sharpening simultaneously, and service time is long, good endurance.Blade is long simultaneously, and sharpening is fit to teaching and uses very much repeatedly.

As Fig. 4, but the equal sharpening bevel in the two ends of blade in the present embodiment when the upset blade, can be realized reverse cutting.

As Fig. 5, Fig. 6, but the equal sharpening in the both sides of blade 2 becomes cutting angle, and when the cutting tip of blade 2 one ends damaged, turning blade 2 continued to use, and does not need to take off at once sharpening, thereby can reduce the sharpening number of times, improves working (machining) efficiency.

Can match by guide rail with elongated slot 3 in blade 2 bottoms, its connection is more solid and reliable, can guarantee the sliding trace of blade along elongated slot.Guide rail can be dove-tail formula (as Fig. 7), also can be various forms such as straight trough form (as Fig. 8) or I-shaped flute profile formula.
