Balance nut

Abstract

The invention relates to the technical field of fasteners, in particular to a balance nut which is of a hexagonal or cylindrical symmetrical balance structure. An inner hole of the nut is provided with an oblong hole with an eccentric circle structure, and a clamping groove around the outer wall of a collet chuck is clamped by two sides of a short shaft of the oblong hole; grooves are formed in one side of the short shaft of the oblong hole and used for weight reducing and balancing, so that the overall weight of the balance nut is uniformly distributed along the circumference; and a small groove is formed in the lower bottom face of the nut and serves as an installation mark, and good assembly and disassembly are achieved. The invention discloses the balance nut which has good dynamic balance and can ensure the stability of a machine tool spindle and a machining tool during high-speed rotation, so that the machining precision and the surface roughness can be ensured; after machining is completed, materials do not need to be removed from the surface, balance correction is not needed, and it is directly ensured that the overall weight is evenly distributed on the circumference structurally; and the collet chuck is easy to deform and easy and efficient to mount and dismount.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a balance nut. Background technique [0002] As is well known, more and more machining centers are used in the machining field at present, and the use of the machining center will use a tool, and the connection between the tool and the handle will use a handle nut. However, with the rapid development of high-speed and high-precision machining, the traditional eccentric structure of the shank nut can no longer meet the requirements of use. [0003] Traditional tool holder nuts have problems in structure, appearance and installation. In severe cases, they can cause vibration of the machine tool spindle and tool system, resulting in wear and tear of the machine tool and destructive accidents. There is an imbalance in the structural design. During the high-speed cutting process, it is easy to cause the chatter of the tool holder head, which will affect the accuracy and surface rou...

However, with the rapid development of high-speed and high-precision machining, the traditional eccentric structure of the shank nut can no longer meet the requirements of use

[0003] Traditional shank nuts have problems in structure, appearance and installation. In severe cases, they can cause vibration of the machine tool spindle and tool system, resulting in wear and tear of the machine tool and destructive accidents.

There is an imbalance in the structural design. During the high-speed cutting process, it is easy to cause the chatter of the tool holder head, which will affect the accuracy and surface roughness of the workpiece to be processed. After processing, it is necessary to drill holes on the surface to remove material to correct the dynamic balance and affect the appearance; During installation and disassembly, the collet is not easy to deform, which makes installation and disassembly difficult and reduces efficiency
