Abstract
It the utility model is related to a kind of CNC machining centers and extend handle of a knife with the formula that is integrally formed, the extension handle of a knife includes a tubular extension rod main body, one end of the tubular extension rod main body forms the stage portion that diameter becomes larger relative to extension rod main body vertically, and the outer end face of the stage portion, which axially extends, forms a round table-like extension;A locking nut is arranged with the periphery of stage portion and round table-like extension, one end inner wall of locking nut forms inner protuberant ring prominent inwardly, and extension rod main body is piercing in the inner protuberant ring, the inner face of inner protuberant ring is opposite with the inner face of stage portion, and assembly clearance is formed between the outer wall of the inner wall of locking nut and round table-like extension.The utility model extends handle of a knife and uses integral structure, and round table-like extension can carry out assembly and connection with the operator handle of various specifications, and versatility is good, is of relatively low cost;Extending handle of a knife integral structure itself need not assemble, and uniformity is good, it can be ensured that precision, so as to improve the precision of CNC small-bores deep processing.
Description
Technical field:
Machining tool technical field is the utility model is related to, refers in particular to a kind of more CNC machining centers with being integrally formed formula
Extend handle of a knife.
Background technology:
With the development of Computerized Numerical Control processing technology, manufacture field often some need to use path deep processing cutter, it is big at present
Majority is that customization lengthens cutter or realized by the extension rod of staight shank, and the cost of manufacture that customization lengthens cutter is high, general
Property it is not strong, and use staight shank extension rod mode, it is main to coordinate ER collet chucks (being also known as ER collets) assembling to extend to be formed, this group
Conjunction mode there are precision it is inadequate the defects of, influence deep processing precision.
Utility model content:
The purpose of the utility model is to overcome the shortcoming of existing product, there is provided a kind of more CNC machining centers one
Formation type extends handle of a knife.
The technical solution adopted in the utility model is:A kind of CNC machining centers extend handle of a knife, the extension with the formula that is integrally formed
Handle of a knife includes a tubular extension rod main body, and one end of the tubular extension rod main body forms diameter relative to extension rod vertically
The stage portion that main body becomes larger, the outer end face of the stage portion, which axially extends, forms a round table-like extension;In stage portion and
The periphery of round table-like extension is arranged with a locking nut, and one end inner wall of locking nut forms inner protuberant ring prominent inwardly,
And extension rod main body is piercing in the inner protuberant ring, the inner face of inner protuberant ring is opposite with the inner face of stage portion, the inner wall of locking nut
Assembly clearance is formed between the outer wall of round table-like extension.
The outer wall of the tubular extension rod main body is from stage portion to the other end in gradually Small Taper shape.
Round table-like extension axially inside offers the axis hole communicated with tubular extension rod main body, and the inner wall of axis hole is opened
Equipped with internal thread.
The utility model extends handle of a knife and uses integral structure, round table-like extension can with the operator handles of various specifications into
Row assembly and connection, versatility is good, is of relatively low cost;Extending handle of a knife integral structure itself need not assemble, and uniformity is good, can
Precision is ensured, so as to improve the precision of CNC small-bores deep processing.
Brief description of the drawings:
Fig. 1 is the sectional view that the utility model extends handle of a knife.
Embodiment:
The utility model is further illustrated with reference to specific embodiments and the drawings.
As shown in Figure 1, described in the utility model is that a kind of CNC machining centers extend handle of a knife 1 with the formula that is integrally formed, this prolongs
Long-cutter holder 1 includes a tubular extension rod main body 11, and one end of the tubular extension rod main body 11 forms diameter vertically
The stage portion 12 to become larger relative to tubular extension rod main body 11, the outer end face of the stage portion 12, which axially extends, forms a round platform
Shape extension 13;It is arranged with a locking nut 2 in the periphery of stage portion 12 and round table-like extension 13, the one of locking nut 2
End inner wall forms inner protuberant ring 21 prominent inwardly, and tubular extension rod main body 11 is piercing in the inner protuberant ring 21, inner protuberant ring 21
Inner face is opposite with the inner face of stage portion 12, formation group between the outer wall of the inner wall of locking nut 2 and round table-like extension 13
Fill gap 100.
It is attached in use, handle of a knife 1 will be extended with operator handle, round table-like extension 13 is inserted into operator pommel portion, is made
Round table-like 13 outer wall of extension and operator handle inner end wall are inconsistent, and locking nut 2 is connected with the external screw thread for handle outer wall of operating, and is utilized
The inner protuberant ring 21 of locking nut 2 is contradicted with 12 inner face of stage portion so that round table-like extension 13 and operator handle locking, tubular
Extension rod main body 11 is integrally formed with stage portion 12, round table-like extension 13, therefore the whole handle of a knife 1 that extends can essence with operator handle
Really stably connect;It is the connecting portion 14 of connection cutter inside the other end of tubular extension rod main body 11, connects cutter.
The outer wall of the tubular extension rod main body 11 is from stage portion to the other end in gradually Small Taper shape, on the one hand convenient locking
Nut 2 is inserted in, and can also increase the scope for being applicable in small-bore deep processing.
Round table-like extension 13 axially inside offers the axis hole 131 communicated with tubular extension rod main body, and axis hole 131
Inner wall offer internal thread 132, cutter or other instruments can also be connected in it, realize positive and negative use.
The utility model extends handle of a knife and uses integral structure, and round table-like extension 13 can be with the operator handle of various specifications
Assembly and connection is carried out, versatility is good, is of relatively low cost;Extending handle of a knife integral structure itself need not assemble, and uniformity is good,
Precision is can ensure that, so as to improve the precision of CNC small-bores deep processing.
