Detailed Description
The following will further describe the cutter head structure according to an embodiment of the present invention with reference to the accompanying drawings.
Please refer to fig. 1 to 3, as shown: the utility model relates to a tool bit structure 1, it is including installing portion 11 and a plurality of sword tooth 12.
The mounting portion 11 is also called a drill pipe or a base body.
Each cutter tooth 12 is arranged in the mounting portion 11 in a circular ring shape, and each cutter tooth 12 has at least one through hole 13, which is provided with a plurality of through holes 13 in the present invention as an embodiment.
In an embodiment of the present invention, the mounting portion 11 is a cylindrical body, and the cutter teeth 12 are arranged in a longitudinal circular ring shape at an end portion of the mounting portion 11.
When the utility model is used, the tool bit structure 1 can be assembled on a drilling machine 2 (such as an RC drilling machine or various drilling machines) by the mounting part 11, and the tool bit structure 1 is driven by the drilling machine 2 to rotate at a high speed, so as to utilize each cutter tooth 12 to perform the required drilling operation; after a period of use, when the cutter teeth 12 are worn to the positions of the through holes 13, one or more acute angles are formed on the end surfaces of the cutter teeth 12 due to the damage of the through holes 13, so as to improve the cutting sharpness of the cutter teeth 12 during cutting, and prevent the cutter teeth 12 from slipping due to wear, thereby prolonging the service life of the cutter head structure 1.
In an embodiment of the present invention, each blade 12 has a blade 121, a connecting surface 122 and a blade surface 123, each connecting surface 122 is disposed on one end edge of each blade 121, each blade surface 123 is disposed on the other end edge of each blade 121, each connecting surface 122 is disposed on the mounting portion 11, and the through hole 13 is disposed on each blade 121. In this way, when the drilling machine 2 drives the cutter head structure 1 to rotate at a high speed, the required drilling (or cutting) operation can be performed by using the cutting edge face 123 of each cutter tooth 12; after a period of use, when the cutting edge surfaces 123 are worn to the positions of the through holes 13 of the cutter bodies 121, acute angles are generated on the end surfaces of the cutter bodies 121 of the cutter teeth 12 due to the damage of the through holes 13, so that the acute angles generated by the through holes 13 on the cutter bodies 121 are used to replace the cutting edge surfaces 123 for drilling (or cutting) operations, thereby maintaining the sharpness of the cutter teeth 12, avoiding the situation that the cutter teeth 12 slip due to wear, and further prolonging the service life of the cutter head structure 1.
In an embodiment of the present invention, each cutter tooth 12 is made of diamond (or other industrial elements). Thus, the cutter head structure 1 can drill (or cut) a harder object by using each cutter tooth 12, so as to maintain the stability during use, and the utility model can meet the requirements of practical use.
In an embodiment of the present invention, the through holes 13 are regularly arranged on the blade 121 of each blade 12. Thus, when the cutting head structure 1 is used for a period of time, and the cutting edge surfaces 123 are worn to the through holes 13 of the cutter bodies 121, the end surfaces of the cutter bodies 121 of the cutter teeth 12 can generate a plurality of acute angles due to the simultaneous damage of the through holes 13, so that the acute angles generated by the through holes 13 on the cutter bodies 121 are used to replace the cutting edge surfaces 123 for performing the required drilling (or cutting) operation, thereby maintaining the sharpness of the cutter teeth 12, avoiding the slippage of the cutter teeth 12 due to the wear, and further prolonging the service life of the cutting head structure 1.
Referring to fig. 4, as shown: in an embodiment of the present invention, the through holes 13 are irregularly arranged on the blade 121 of each blade. This is done. When the cutting head structure 1 is used for a period of time, and the cutting edge surfaces 123 are worn to the positions of the through holes 13 of the cutter bodies 121, the end surfaces of the cutter bodies 121 of the cutter teeth 12 can generate a plurality of acute angles due to the respective damages of the through holes 13, so that the acute angles generated by the through holes 13 on the cutter bodies 121 are used to replace the cutting edge surfaces 123 for performing required drilling (or cutting) operation, thereby maintaining the sharpness of the cutter teeth 12, avoiding the situation that the cutter teeth 12 slip due to wear, and further prolonging the service life of the cutting head structure 1.
Referring to fig. 5, as shown: in an embodiment of the present invention, each through hole 13 is a knife tooth 12 regularly arranged in one portion, and each through hole 13 is a knife tooth 12 irregularly arranged in another portion, for example: the through holes 13 arranged regularly and irregularly can be respectively arranged on the cutter teeth 12 in a staggered manner. Thus, when the cutting head structure 1 is used for a period of time, and the blade surfaces 123 of some of the cutter teeth 12 are worn to the positions of the through holes 13 of the cutter bodies 121, the end surfaces of the cutter bodies 121 of some of the cutter teeth 12 can generate a plurality of acute angles due to the damage of the through holes 13, so that the acute angles generated by the through holes 13 on the cutter bodies 121 are used for replacing the blade surfaces 123 to perform the required drilling (or cutting) operation; in addition, when the cutting head structure 1 is used for a while, and the blade surfaces 123 of the other portion of the cutter teeth 12 are worn to the positions of the through holes 13 of the cutter bodies 121, the end surfaces of the cutter bodies 121 of the other portion of the cutter teeth 12 are acutely angled due to the breakage of the through holes 13, so that the acute angle formed by the through holes 13 in the cutter bodies 121 is used to perform a desired drilling operation instead of the blade surfaces 123. Therefore, one part of the cutter teeth 12 and the other part of the cutter teeth 12 are matched with each other for use, so that the sharpness of each cutter tooth 12 is kept, the phenomenon that each cutter tooth 12 slips due to abrasion is avoided, and the purpose of prolonging the use of the cutter head structure 1 is achieved.
Referring to fig. 6, as shown: in an embodiment of the present invention, the mounting portion 11 is a disk-shaped body, and the cutter teeth 12 are arranged in a horizontal circular ring shape on an outer periphery of the mounting portion 11. Thus, the cutting head structure 1 can be assembled to a cutting machine (for example, an RC cutting machine or various cutting machines, not shown) by the mounting portion 11, and when the cutting head structure 1 is driven by the cutting machine to rotate at a high speed, the cutting operation can be performed by the blade face 123 of each blade tooth 12; after a period of use, when the blade surfaces 123 are worn to the positions of the through holes 13 of the blade bodies 121, the end surfaces of the blade bodies 121 of the cutter teeth 12 generate acute angles due to the damage of the through holes 13, so that the acute angles generated by the through holes 13 on the blade bodies 121 are used to replace the blade surfaces 123 for performing required cutting operations, thereby maintaining the sharpness of the cutter teeth 12, avoiding the situation that the cutter teeth 12 slip due to wear, and further prolonging the use of the cutter head structure 1.
To sum up, the embodiment of the utility model provides a tool bit structure can be with the utility model discloses a tool bit structure is installed in drilling machine or cutting machine through the portion of installing to carry out the cutting work of drilling or cutting through the sword tooth, when the sword tooth has fenestrate position to the sword tooth because of wearing and tearing, alright make perforation damage and produce one or more acute angles, sharpness when cutting promotes, avoids the sword tooth to skid when cutting simultaneously, and then increases the sharpness of cutting, and the life of extension tool bit structure.
