Description
Technical field
The utility model relates to toolroom machine field, the technical field of the cutter structure of espespecially replaceable cutter head.
Background technology
Press, general high-speed steel tool is formed by high-speed steel material institute car system, because the hardness of high-speed steel is lower, easily produce loss, therefore its service life is short at this cutting portion after repeatedly using.Therefore, dealer is in order to extend cutting-tool's used life, and the wolfram steel material that hardness can be adopted high is to manufacture cutter, but expensive due to wolfram steel, all manufactured by wolfram steel to whole cutter, its cost is quite high, and still whole cutter must be abandoned after its consume, considerably cost of idleness.
Refer to shown in Fig. 4, then just by dealer by a cutter hub 92 and a handle of a knife 91 form an existing replacing cutter 9, wherein the material of this handle of a knife 91 is made by general steel, and a cutting part 921 material set by cutter hub 92 is usually made by wolfram steel material.This cutter hub 92 establishes this cutting portion 921 bottom it again, and the center, top of this cutter hub 92 is provided with one in conjunction with screw rod 922, this can be inserted in combination for one set by one end of a handle of a knife 91 in conjunction with screw 911 in conjunction with screw rod 922, and this in conjunction with screw 911 with this in conjunction with screw rod 922 after being socketed, utilizing thread locking combination, this cutter hub 92 is firmly being incorporated on this handle of a knife 91.
But above-mentioned existing replacing cutter 9, because its handle of a knife 91 uses general steel, therefore its lateral rigidity still dislikes not enough, in the machining amount of feeding is large when, easily has shake cutter phenomenon and damages the machined surface of tungsten steel blade and workpiece, the space be improved in fact.
Moreover, above-mentioned existing replacing cutter 9 uses thread locking combination, higher precision cannot be reached, when causing this cutter 9 to be used in processing machine, under running up, easily cause outside this processing machine shakes, be machined in the machined surface of workpiece, easy generation tool marks, so just cannot the precision of lifting workpieces machined surface.
Summary of the invention
In view of the problem points of above-mentioned existing cutter, so therefore the utility model creator creates the utility model cutter structure, its main object: the cutter structure being the alternate form cutter head providing low cost; Secondary objective of the present utility model: be the cutter structure that high rigidity, high-precision alternate form cutter head are provided.
For reaching above-mentioned purpose, the cutter structure institute application technology means of the utility model alternate form cutter head include: a handle of a knife, and be the body of rod of tool one first external diameter, a joint portion is extended in one end, and this joint portion is formed with one second external diameter; And a cutter head, for tool one is in conjunction with the bite portion of hole slot, and this combined hole groove is formed with an internal diameter, and this internal diameter size is less than the second external diameter of the joint portion of this handle of a knife, and this must be inserted in combination for the joint portion of this handle of a knife in conjunction with hole slot again; By heating this cutter head and cooling, use the sintering theory expanded with heat and contract with cold, thus can install for this cutter head, dismantle on the joint portion of this handle of a knife.
Second outside dimension of this handle of a knife above-mentioned is less than the first outside dimension of this handle of a knife.
This handle of a knife above-mentioned is made by wolfram steel material.
This cutter head above-mentioned is made up of a tool rest, multiple blade, and the plurality of blade must be arranged on this tool rest, and this tool rest is made by heat resisting steel.
The cutter structure above technological means of the utility model alternate form cutter head, following effect can be reached:
The utility model cutter structure uses the sintering theory expanded with heat and contract with cold, can install for this cutter head, dismantle in this handle of a knife, treat the service life of this cutter head at the end, the removable cutter head renewed, and the Master Cost of handle of a knife can be saved, and then produce the cutting tool of low cost.
Due to the handle of a knife of the utility model cutter structure, use made by wolfram steel material, therefore its lateral rigidity is enough, precision can be promoted about to the margin of tolerance of 0.003mm, even if the utility model cutting tool is in the machining of roughing feed when, its machining accuracy, also has the effect of lifting.

Detailed description of the invention
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
First, refer to shown in Fig. 1 ~ Fig. 3, the utility model is about a kind of cutter structure of alternate form cutter head, and namely the cutting tool of this alternate form cutter head includes: handle of a knife 10 and a cutter head 20; Wherein,
This handle of a knife 10, for a joint portion 111 is extended in the body of rod 11 one end of tool one first outside diameter d 1, and this joint portion 111 is formed with one second outside diameter d 2, and the second outside diameter d 2 size of this handle of a knife is less than the first outside dimension d1 of this handle of a knife again; Special one carries, and this handle of a knife 10 is set to made by wolfram steel material; And
This cutter head 20, for tool one is in conjunction with the bite portion of hole slot 211, and this is formed with an internal diameter D in conjunction with hole slot 211, and this internal diameter D size is less than the second outside diameter d 2 of the joint portion 111 of this handle of a knife 10, and this is inserted in combination in conjunction with hole slot 211 for the joint portion 111 of this handle of a knife 10 again; Further, this cutter head 20 is made up of a tool rest 21, multiple blade 22, and the plurality of blade 22 is arranged on this tool rest 21, and this tool rest 21 is made by heat resisting steel.
The each element of above forms the cutting tool 1 of the utility model alternate form cutter head, this cutter head 20 is heated and cooled, use the sintering theory expanded with heat and contract with cold, can install for this cutter head 20, dismantle on the joint portion 111 of this handle of a knife 10, treat the service life of this cutter head 20 at the end, the removable cutter head 20 renewed, and the Master Cost of handle of a knife can be saved, and then produce the cutting tool of low cost.That is when mounting cutter, obtain and in advance this cutter head 20 is heated, it is made to expand because of expansion in conjunction with hole slot 211, and then the joint portion 111 of the body of rod 11 of this handle of a knife 10 is inserted in is installed on this in conjunction with in hole slot 211, this must press from both sides in conjunction with hole slot 211 and restraint this body of rod 11, this handle of a knife 10, cutter head 20 to be combined securely after cooling.
Moreover, the handle of a knife 10 of the cutting tool 1 of the utility model alternate form cutter head, use made by wolfram steel material, therefore its lateral rigidity is enough, precision can be promoted about to the margin of tolerance of 0.003mm, even if the utility model cutting tool is in the machining of roughing feed when, its machining accuracy, also has the effect of lifting.
