Description
Technical Field
The invention relates to the technical field of machining tools, in particular to a positive and negative combined type multipurpose tool.
Background
As the competition of the processing industry increases, the processing industry places higher demands on the time and quality required for processing. The traditional process needs the working procedures of drilling, milling and surface milling and the like for hole processing, and can be realized only by a plurality of cutters.
Therefore, there is a need in the art for a tool that can integrate the functions of multiple tools and can be used for multiple machining processes at a time.
Disclosure of Invention
The object of the invention is to solve the problems existing in the prior art
The technical scheme adopted for achieving the purpose of the invention is that the positive and negative composite multipurpose cutter is characterized by comprising a cutter handle and a cutter body.
A circle of annular groove is formed in the outer wall of the knife handle.
The integral structure of the cutter body is of a double-edge straight groove-shaped structure.
The cutter body comprises an end structure, a connecting structure, a middle structure and a head structure which are sequentially connected from left to right.
One end of the end structure of the cutter body is connected with the end face of the cutter handle.
The diameter of the end face of one end, connected with the end structure, of the connecting structure is larger than that of the end face of one end, connected with the middle structure, of the connecting structure.
One end of the head structure is of a tip structure, and the other end of the head structure is connected with the end face of the middle structure.
The maximum diameter of the head structure is greater than the diameter of the middle structure and less than the diameter of the end structures.
The tip structure of the head structure comprises two end edges. Two cooling holes are further formed in the tip structure surface of the head structure.
The two end edges are in a central symmetrical structure. The two cooling holes are also centrosymmetric.
The head structure is provided with a top rear angle.
Furthermore, the cutter bar and the cutter body are both made of hard alloy materials.
Furthermore, the cutter groove and the cutting edge of the combined type cutter are both formed by grinding diamond.
The technical effects of the present invention are undoubted, and the present invention has the following advantages:
1) in the traditional processing, only drilling and front chamfering can be carried out, reverse chamfering cannot be processed in place, and products can be processed or reinstalled by reversing the products;
the back corner of the centre designed at the front end of the cutter can be chamfered on the front side and the back side, so that the processing time is greatly reduced, and the working efficiency is improved;
2) the invention integrates multi-directional processing points, improves the traditional efficiency by 3-5 times, greatly reduces the cost and enables the cutter to be more stable.
Drawings
FIG. 1 is a schematic view of a cutter in embodiment 1;
fig. 2 is a schematic end view of the tool of fig. 1.
In the figure: the tool comprises a tool shank 1, an annular groove 101, a tool body 2, an end structure 201, a connecting structure 202, a middle structure 203, a head structure 204, an end edge 2041 and a cooling hole 2042.
Detailed Description
The present invention is further illustrated by the following examples, but it should not be construed that the scope of the above-described subject matter is limited to the following examples. Various substitutions and alterations can be made without departing from the technical idea of the invention and the scope of the invention is covered by the present invention according to the common technical knowledge and the conventional means in the field.
Example 1:
as shown in fig. 1 and 2, a positive and negative composite multipurpose tool is characterized by comprising a tool shank 1 and a tool body 2.
A circle of annular groove 101 is formed in the outer wall of the cutter handle 1.
The whole structure of the cutter body 2 is a double-edge straight groove structure.
The cutter body 2 comprises an end structure 201, a connecting structure 202, a middle structure 203 and a head structure 204 which are connected in sequence from left to right.
One end of the end structure 201 of the cutter body 2 is connected with the end surface of the cutter handle 1.
The connecting structure 202 has a larger diameter at the end connected to the end structure 201 than at the end connected to the middle structure 203.
One end of the head structure 204 is an apex structure, and the other end is connected with the end face of the middle structure 203.
The maximum diameter of the head structure 204 is greater than the diameter of the central structure 203 and less than the diameter of the end structure 201.
The tip structure of the head structure 204 includes two end edges 2041. Two cooling holes 2042 are also formed in the tip structure surface of the head structure 204.
The two end edges 2041 are of a central symmetrical structure. The two cooling holes 2042 are also centrosymmetric.
The head structure 204 is provided with tip relief angles.
The cutter bar 1 and the cutter body 2 are both made of hard alloy materials.
The cutter groove and the cutter edge of the combined type cutter are both formed by grinding diamond.
In the traditional processing, only drilling and front chamfering can be carried out, reverse chamfering cannot be processed in place, and products can be processed or reinstalled by reversing the products;
the back corner of the centre designed at the front end of the cutter in the embodiment can be chamfered on the front side and the back side, so that the processing time is greatly reduced, and the working efficiency is improved; the cutter in this embodiment has still fused diversified processing point, makes traditional efficiency improve 3 ~ 5 times, and the cost is reduced of very big degree makes the cutter more stable.
