Abstract

The utility model discloses a cutter arbor which is used for machining and belongs to the technology of a cutter class and a cutting-tool class. The utility model comprises a main body of the cutter arbor and a press plate, a cutter groove is opened in the front middle of the main body of the cutter arbor to store a blade, a rabbet is opened on the position of the press plate, the position is corresponding to the cutter groove, the press plate is connected with the main body of the cutter arbor by screws to fasten the blade, three to six countersunk threaded holes of M6 are drilled on the upper face of the main body of the cutter bar to compact the blade from the upper face. The utility model overcomes the shortcomings that the existing lathe tool needs to grind when in use, the human power and the electric force are wasted, the utilization ratio of high speed steel materials is low, etc. The labour productivity can be raised more than 20%, and the utilization ratio of the materials can be raised more than 3 times.

Description

A kind of knife bar

The utility model relates to the knife bar that a kind of machining is used, and belongs to cutter, cutlery class technology.

China's used lathe tool specification at present mostly is 12 * 12mm, 14 * 14mm, 16 * 16mm, 18 * 18mm, is ground to the wide cutter head of 1-5mm in the cutting use.This has not only wasted a large amount of manpowers, electric power, and has more seriously wasted the high-speed steel material of mass expensive, and stock utilization only has 10-20%.

The purpose of this utility model be for provide a kind of simple in structure, easy to use, can raise labour productivity, reduce power consumption and improve the knife bar of high-speed steel stock utilization.

The technical solution of the utility model is achieved in that a kind of knife bar, constitute by knife bar main body (2) and pressing plate (4) two parts, front in knife bar main body (2) is drilled with a screw respectively for four jiaos, its central part has the cutter groove (6) that a wide 12-18mm, dark 3-5mm, length equate with knife bar main body (2), so that deposit tool section (1); Be provided with the countersunk head screw (3) of 3-6 M6 directly over knife bar main body (2), countersunk head screw (3) runs through knife bar main body (2), so that compress tool section (1) from above; Pressing plate (4) is in knife bar main body (2) front, and its size equates that with the front of knife bar main body (2) high 1mm is left in the corresponding position of pressing plate (4) and cutter groove (6), and the wide seam that equates of wide and cutter groove (6) is so that compress tool section (1) more firmly; Four jiaos of four screw corresponding positions, front with knife bar main body (2) of pressing plate (4) are drilled with a through hole respectively, so that the screw of screwing on compresses tool section (1) from the front.

The utility model in use can be raised labour productivity more than 20%, reduces power consumption 10%, and the high-speed steel material of costliness can be made full use of, and increases operation rate more than 3 times.

Fig. 2 is an A-A cutaway view of the present utility model

Is that example is described in further detail the utility model below in conjunction with accompanying drawing with the C620 tool holder of lathe.

Leave a wide 14mm in the front of knife bar main body (2), the cutter groove (6) of dark 5mm, bore a screw respectively for four jiaos in the front of knife bar main body (2) again, directly over it, bore the countersunk head screw (3) of 3 M6 then, so that be screwed into the countersunk head soket head cap screw, tool section (1) is compressed from above, pruned in the positive both sides of pressing plate (4) of thick 4mm, high 1mm is reserved in middle and cutter groove (6) corresponding position, the seam of wide 14mm, the back is bored a through hole respectively in four screw corresponding positions of Qi Sijiao and knife bar main body (2), so that screw on screw, compress knife bar (1) from the side, promptly get a kind of knife bar described in the utility model.

Claims

1, a kind of knife bar, it is characterized in that: it is made up of knife bar main body (2) and pressing plate (4) two parts, front in knife bar main body (2) is drilled with a screw respectively for four jiaos, its central part has a wide 12-18mm, the long cutter groove (6) that equates with knife bar main body (2), be provided with the countersunk head screw (3) of 3-6 M6 directly over it, screw (3) runs through knife bar main body (2); The front of knife bar main body (2) is provided with pressing plate (4), and four jiaos of four screw corresponding positions with knife bar main body (2) front of pressing plate (4) are drilled with a through hole respectively.

2, a kind of knife bar as claimed in claim 1 is characterized in that high 1mm is left, the seam that width wide and cutter groove (6) equates in the corresponding position of pressing plate (4) and cutter groove (6).
