Abstract
The utility model discloses a cutter extension rod, including an extension rod body, this extension pipe body inside axle center position forms a first perforation along the axial, and the tip forms the great gomphosis portion of diameter before the first perforation, and a spiral shell union pipe, spiral shell union pipe inlays establishes to be fixed in this gomphosis portion and forms a second perforation in inside axle center position along the axial, and this second perforation perisporium forms a screw thread portion, extension rod body be the tungsten steel pipe, spiral shell union pipe be the tool steel pipe, the diameter of second perforation is greater than first perforation and form the great holding part of diameter at the tip, and the screw thread portion forms the second perforation perisporium at this holding part rear side, the utility model discloses when using, provide cutter lock with the screw thread portion, because spiral shell union pipe and extension rod body are two different body, consequently, spiral shell union pipe can select the tool steel body that can directly process with the cutter and utilize the cutter processing screw thread portion, therefore, the utility model has the advantages of easy manufacture and low processing cost and provides the efficacy of prolonging the cutter.
Description
Technical field:
The utility model relates to a kind of part of milling cutter, refers to a kind of cutter extension rod that prolongs cutter especially.
Background technology:
Prior art cutter extension rod, please referring to Fig. 4, it has a wolfram steel body 40, forms a threaded portion 41 in the front end of wolfram steel body 40,, reaches whereby to prolong the effect of cutter for tool rest 30 screw locks with threaded portion 41.
Therefore the wolfram steel body of above-mentioned cutter extension rod is because hardness is harder, during machining screw portion 41, need carry out with discharge processing in wolfram steel body 40 front ends, causes processing inconvenience and the high problem of cost.
Other has a kind of existing cutter extension rod as shown in Figure 5, it has a wolfram steel bar 50, weld a tool steel body 51 in wolfram steel bar 50 front ends, in tool steel body 52, form a threaded portion 511, can make cutter carry out the processing of screw cutting portion 511 by softer tool steel body 51, therefore processing is comparatively saved trouble, yet, wolfram steel bar 50 aligns the weld job of tool steel body 51 owing to need higher precision, and is therefore also inconvenient in the processing.
The cutter extension rod of prior art all has machining screw portion and is difficult for and causes the high difficult problem of cost.
Summary of the invention:
The purpose of this utility model is to provide with the technological means that two-piece member combines the cutter extension rod of handling ease, to address the above problem.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
The cutter extension rod, it comprises an extension rod body, this prolongation tube body internal axis position forms one first perforation vertically, form the bigger fitting portion of a diameter in the first perforation leading section, and one screw togather pipe, this screws togather pipe and is embedded and is fixed in this fitting portion and forms one second perforation in the internal axis position vertically, forms a threaded portion in this second perforation perisporium.
Described extension rod body is the wolfram steel pipe, and the described pipe that screws togather is the instrument steel pipe, and the diameter of described second perforation forms the bigger holding part of a diameter greater than first perforation and in leading section, and described threaded portion is formed at the second perforation perisporium of this holding part rear side.
The described outer peripheral face that screws togather pipe tightly fits in the perisporium of described fitting portion.
Described screw togather the pipe brazing be incorporated in the described fitting portion.
Be provided with one deck AB glue-line between the perisporium of described outer peripheral face that screws togather pipe and described fitting portion.
When the utility model uses, provide the cutter screw lock with the threaded portion, because screwing togather pipe is two different bodys with the extension rod body, therefore, screwing togather pipe can select for use and can and utilize cutter machining screw portion with the direct tool steel body of processing of cutter, therefore, the utlity model has the low advantage of easy manufacturing processing cost and the effect that prolongs cutter is provided.

The specific embodiment:
The utility model is the cutter extension rod, see also Fig. 1-Fig. 3, it comprises that an extension rod body 10 and is incorporated into screwing togather of extension rod body 10 leading sections and manages 20, wherein, extension rod body 10 forms one first perforation, 11, the first perforation 11 vertically and forms the bigger fitting portion of a diameter 111 for circular hole and in leading section for circular wolfram steel straight tube and in the internal axis position.
Screw togather pipe 20 and be slightly larger than the circular tool steel pipe of fitting portion 111 for external diameter, screw part 20 is for inserting in the fitting portion 111 after sub-cooled is shunk earlier again, treating that screw part 20 replys can be embedded with the tight fit form whereby after the sizes is fixed in the fitting portion 111, screw togather pipe 20 and form one second perforation 21 in the internal axis position vertically, second perforation, 21 diameter forms the bigger holding part of a diameter 211 greater than first perforation 11 and in front end, forms a threaded portion 212 in second perforation, 21 perisporiums of holding part 211 rear sides.
The utility model screwed pipe 20 except be embedded the fitting portion 111 that is incorporated into extension rod body 10 with the tight fit form in, can also be with brazing or with the AB glue bond, be provided with one deck AB glue-line adhering technique means in screwing togather between pipe outer peripheral face and the fitting portion perisporium whereby, to screw togather pipe 20 in conjunction with being positioned fitting portion 111, when the utility model uses, provide tool rest 30 screw locks with threaded portion 212, the effect that reaches easy manufacturing whereby, cost is low and prolongs cutter.
