Abstract
The invention relates to a tool for machining a casing pipe with buttress threads. The tool for machining the casing pipe with the buttress threads comprises a tool body, wherein two working faces are arranged on one side face of the tool body, a locating face is arranged on the opposite side face of the tool body, the two working faces are slopes, the inclined included angle between each working face and the horizontal plane is 5 degrees 5 minutes +/-5 minutes, two locating holes are formed in the tool body, a cutting tooth portion is arranged on each working face of the tool body, each cutting tooth portion is composed of a fine cutting tooth and a rough cutting tooth, the fine cutting teeth and the rough cutting teeth are of a buttress shape, and chip discharging circular-arc faces are arranged below the working faces. The tool for machining the casing pipe with the buttress threads is low in cutting resistance and high in machining accuracy; due to the fact that the chip discharging circular-arc faces are arranged on the tool body, the effect of chip discharging is improved, and scrap iron is prevented from intertwining and accumulating; due to the fact that the two locating holes are formed in the tool body, the tool can be firmly fixed; due to the facts that the two working faces are arranged on the tool body, and the working faces are arranged on the same side of the tool body, in the process of cutting operation, switching between the working faces can be more convenient.
Description
Technical field
The present invention relates to threading tool field, particularly a kind of for processing the cutter of BCSG.
Background technology
In turning processing, buttress thread is because total cutting depth is large, and tool dimension is subject to the restriction of trapezoidal thread physical dimension.On market, existing tool stiffness is poor, and precision is low, and cutting resistance and impulsive force are large, and chip removal is not smooth, and iron filings are easily wound around, and makes cutting edge excess Temperature, serious wear, cutting edge easy fracture.In addition, cutter working face is inconvenient to change, and inefficiency, and fixing insecure on lathe of cutter easily produce vibration.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides that a kind of cutting resistance is little, chip removal is smooth and easy, conversion work face is more convenient, fixation for processing the cutter of BCSG.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions: a kind of for processing the cutter of BCSG, comprise cutter hub, a side of described cutter hub is provided with two working faces, another relative side is provided with locating surface, described two working faces are inclined-plane, slanted angle between described each working face and horizontal plane be 5o15 ' ± 5 ', described cutter hub is provided with two locating holes, each working face of described cutter hub is provided with a cutting teeth portion, described each cutting teeth portion is comprised of 1 finishing tooth and 1 roughing tooth, described finishing tooth and roughing tooth are partially trapezoidal, described working face below is provided with chip removal arc surface.
Further, the radius of described chip removal arc surface is 0.8mm.
Further, the profile of tooth of finishing tooth and roughing tooth by tooth top circular arc-straight line profile of tooth, tooth at the bottom of circular arc-straight line profile of tooth and flank straight line profile of tooth form.
The invention has the beneficial effects as follows: of the present invention for processing the cutter of BCSG, its cutting teeth portion is comprised of 1 finishing tooth and 1 roughing tooth, and cutting resistance is little, and machining accuracy is high; Cutter hub is provided with chip removal arc surface, has strengthened chip removal effect, prevents winding and the accumulation of iron filings; Cutter hub is provided with two locating holes, makes cutter fixation; Cutter hub is provided with two working faces, and these two working faces are in the same side of cutter hub, and in cutwork, conversion work face is more convenient.
Accompanying drawing explanation
Fig. 1 is that the present invention is for processing the cutter structure schematic diagram of BCSG.
Fig. 2 be in Fig. 1 along the cutaway view of A-A line.
Fig. 3 is that the present invention is for processing the structural representation of the cutter cutting teeth portion of BCSG.
Number in the figure explanation: 1: cutter hub; 2: working face; 3: locating surface; 4: cutting teeth portion; 41: finishing tooth; 42: roughing tooth; 5: chip removal arc surface; 6: locating hole.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
As shown in Figure 1 to Figure 3, a kind of for processing the cutter of BCSG, comprise cutter hub 1, a side of described cutter hub 1 is provided with two working faces 2, another relative side is provided with locating surface 3, described two working faces 2 are inclined-plane, the slanted angle between each working face 2 and horizontal plane be 5o15 ' ± 5 ', cutter hub 1 is provided with two locating holes 6.Two locating holes 6 make fixing more firm on lathe of cutter, and two working faces 2 are positioned at the same side of cutter hub 1, make in work conversion work face more convenient.Each working face 2 of cutter hub 1 is provided with a cutting teeth portion 4, and each cutting teeth portion 4 is comprised of 1 finishing tooth 41 and 1 roughing tooth 42, and finishing tooth 41 and roughing tooth 42 are partially trapezoidal, and when processing buttress thread, cutting resistance is little, and machining accuracy is high.Working face below is provided with chip removal arc surface 5, and in the present embodiment, the radius R of chip removal arc surface is 0.8mm, strengthens chip removal effect.
In addition, the profile of tooth of finishing tooth and roughing tooth by tooth top circular arc-straight line profile of tooth, tooth at the bottom of circular arc-straight line profile of tooth and flank straight line profile of tooth form.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
