Abstract
The utility model discloses a novel thread milling cutter. Comprises a cutter bar, a chip groove, a positioning groove and a thread blade; chip grooves are symmetrically arranged on the cutter rod, extend from the end part of the cutter rod to the middle section of the cutter rod, and are provided with positioning grooves; the outer side surface of the thread blade is a thread surface, the inner side surface of the thread blade is a positioning surface, the positioning surface is structurally matched with the positioning groove, the thread blade is installed in the positioning groove through the positioning surface, and the thread surface of the thread blade is higher than the surface of the cutter bar; the locating slot is a dovetail groove structure, and the locating surface is a wedge block matched with the dovetail groove. The utility model discloses a detachable only needs the screw thread blade to adopt carbide to make, greatly reduced cutter material cost. After the threaded blade reaches the service life, only the threaded blade needs to be replaced, repeated tool setting and alignment are not needed, and the machining efficiency is improved. The thread blade is positioned by adopting a dovetail groove, the contact area between the thread blade and the positioning groove is large, the fixation is firmer, and the impact resistance is strong.
Description
The technical field is as follows:
the utility model belongs to the technical field of the cutter production, in particular to novel thread milling cutter.
Background art:
the conventional thread milling cutter is usually made of integral hard alloy, the production and machining cost is high, and the whole thread milling cutter needs to be replaced after the cutter reaches the service life, so that the material cost is increased. The replaced cutter still needs to be repeatedly set, and the machining efficiency is influenced.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.
The utility model has the following contents:
an object of the utility model is to provide a novel thread milling cutter to overcome the defect among the above-mentioned prior art.
In order to achieve the above object, the utility model provides a novel thread milling cutter, include: the cutter bar, the chip groove, the positioning groove and the thread blade; chip grooves are symmetrically arranged on the cutter rod, extend from the end part of the cutter rod to the middle section of the cutter rod, and are provided with positioning grooves; the outer side surface of the thread blade is a thread surface, the inner side surface of the thread blade is a positioning surface, the positioning surface is structurally matched with the positioning groove, the thread blade is installed in the positioning groove through the positioning surface, and the thread surface of the thread blade is higher than the surface of the cutter bar; the locating slot is a dovetail groove structure, and the locating surface is a wedge block matched with the dovetail groove.
Preferably, in the technical scheme, the positioning groove accounts for 60% of the length of the chip removal groove.
Compared with the prior art, the utility model discloses following beneficial effect has:
the blades of the thread milling cutter are detachable, and only the thread blades are made of hard alloy, so that the material cost of the cutter is greatly reduced. After the threaded blade reaches the service life, only the threaded blade needs to be replaced, repeated tool setting and alignment are not needed, and the machining efficiency is improved. The thread blade is positioned by adopting a dovetail groove, the contact area between the thread blade and the positioning groove is large, the fixation is firmer, and the impact resistance is strong.

The specific implementation mode is as follows:
the following detailed description of the embodiments of the present invention is provided, but it should be understood that the scope of the present invention is not limited by the embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
Example 1
As shown in fig. 1-5, a novel thread milling cutter comprises a cutter bar 1, a chip groove 2, a positioning groove 3 and a thread blade 4; chip grooves 2 are symmetrically formed in the cutter rod 1, the chip grooves 2 extend from the end part of the cutter rod 1 to the middle section of the cutter rod 1, positioning grooves 3 are formed in the chip grooves 2, and the positioning grooves 3 account for 60% of the length of the chip grooves 2; the outer side surface of the thread blade 4 is a thread surface 5, the inner side surface of the thread blade 4 is a positioning surface 6, the positioning surface 6 is structurally matched with the positioning groove 3, the thread blade 4 is installed in the positioning groove 3 through the positioning surface 6, and the thread surface 5 of the thread blade 4 is higher than the surface of the cutter bar 1; the positioning groove 3 is of a dovetail groove structure, the positioning surface 6 is a wedge block matched with the dovetail groove, and the threaded blade 4 is fixed on the positioning groove 3 by inserting the wedge block into the dovetail groove.
As shown in fig. 6, the thread milling cutter drills and mills the workpiece to form a threaded hole. The thread milling cutter has the advantages that the thread blade 4 is detachable, and the thread blade 4 is made of hard alloy, so that the material cost of the cutter is greatly reduced. After the threaded blade 4 reaches the service life, only the threaded blade 4 needs to be replaced, repeated tool alignment is not needed, and the machining efficiency is improved. Threaded blade 4 adopts the dovetail location, compares in the current structure of adopting the screw to fix the blade, and threaded blade 4 is big with the 3 indirect contact areas of constant head tank, and is fixed more firmly, and is able to bear or endure the impact force by force.
The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the invention and various alternatives and modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
