Abstract
The utility model relates to a kind of shaping knife bar for worked door hinge body part circular arc, comprise the clamping part and operate portions that are connected, described operate portions comprises front end workpiece and the rear end workpiece of coaxial setting, described front end workpiece, rear end workpiece, clamping part connect successively, the diameter of described front end workpiece is less than the diameter of rear end workpiece, and described operate portions sidewall is provided with chip area.Compared with prior art, the utility model has and can improve the advantages such as working (machining) efficiency.
Description
Technical field
The utility model relates to a kind of arc machining cutter, especially relates to a kind of shaping knife bar for worked door hinge body part circular arc.
Background technology
In machining, often can run into some products and contain one group of concentric holes system and need processing, and the axiality in the system of hole between Kong Yukong requires stricter.As existing processing technology is arranged to different size gradation processing, hole or the circular arc of Φ 32 and Φ 40 (or other different size) is processed as a workpiece needs, then adopt two slotting cutters being of a size of Φ 32 and Φ 40 to process at twice, Milling Process goes out two isocentric circular arc.This mode lathe is long for non-cutting time, and the process rhythm time is long, and efficiency is low, and cost is very high, and form and position tolerance concentricity comparatively Customers ' Legal Right, causes product competitiveness in the market to decline.
Summary of the invention
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of shaping knife bar for worked door hinge body part circular arc improving working (machining) efficiency is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of shaping knife bar for worked door hinge body part circular arc, comprise the clamping part and operate portions that are connected, described operate portions comprises front end workpiece and the rear end workpiece of coaxial setting, described front end workpiece, rear end workpiece, clamping part connect successively, the diameter of described front end workpiece is less than the diameter of rear end workpiece, and described operate portions sidewall is provided with chip area.
The end of described front end workpiece is evenly distributed with three the first cutting planes, and the end face of three the first cutting planes in one plane;
The end of described rear end workpiece is evenly distributed with three the second cutting planes, and the end face of three the second cutting planes in one plane;
Described first cutting plane is all removably connected a blade by blade fastening bolt holes with the second cutting plane.
Described chip area is located between two adjacent the first cutting planes, and extends between two adjacent the second cutting planes.
Described clamping part is provided with the installing hole for described shaping knife bar being fixed on lathe.
The ratio that the diameter of described front end workpiece is less than the diameter of rear end workpiece is 2 ~ 4: 5.
Compared with prior art, the utility model has the following advantages:
1, one-shot forming reduces process time, improves working (machining) efficiency;
2, the concentricity of two circular arcs can effectively be ensured in the utility model two process;
3, the utility model adopts detachable blade, and knife bar only needs more allowing blade replacement can continue processing, without the need to reconditioning;
4, side, utility model works portion is provided with chip area, processes convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As Figure 1-Figure 2, a kind of shaping knife bar for worked door hinge body part circular arc that the utility model embodiment provides, comprise the clamping part 2 and operate portions 1 that are connected, operate portions comprises front end workpiece and the rear end workpiece of coaxial setting, front end workpiece, rear end workpiece, clamping part 2 connect successively, and the diameter of front end workpiece is less than the diameter of rear end workpiece, and its ratio can be set as 2 ~ 4: 5 as required, if front end workpiece is Φ 32, rear end workpiece is Φ 40.
The end of front end workpiece is evenly distributed with three the first cutting planes 3,120 °, interval setting between two, and the end face of three the first cutting planes 3 in one plane; The end of rear end workpiece is evenly distributed with three the second cutting planes 4,120 °, interval setting between two, and the end face of three the second cutting planes 4 in one plane; First cutting plane 3 is all removably connected a blade 5 by blade fastening bolt holes 6 with the second cutting plane 4.
Operate portions 1 sidewall is provided with chip area 7, and chip area 7 is located between two adjacent the first cutting planes 3, and extends between two adjacent the second cutting planes 4.
Clamping part 2 is provided with the installing hole 8 for shaping knife bar being fixed on lathe, can fixingly on lathe easily use.
Shaping knife bar of the present utility model, after installing blade, is fixed on lathe, the mode of Milling Process can once complete the processing of two different-diameter isocentric circular arc, decrease process time.
