Description

Technical Field

[0001] This utility model relates to the field of milling technology, specifically to a ball end mill with stable vibration reduction. Background Technology

[0002] Milling is a common machining method. A milling machine fixes the workpiece on a worktable and uses a rotating milling cutter to perform cutting operations. Milling is commonly used for machining materials such as metals and plastics, and can perform various machining operations such as planar, curved, grooving, and hole machining. During milling, operators need to select appropriate tools, machining parameters, and process routes according to the requirements of the workpiece to ensure machining quality and efficiency. Milling is widely used in fields such as machinery manufacturing, aerospace, automotive manufacturing, and mold manufacturing, and is one of the most common machining methods in manufacturing. With the development of CNC technology, CNC milling machines have replaced traditional milling machines as the mainstream, improving machining accuracy and production efficiency, and promoting the development of industrial manufacturing.

[0003] Most existing ball end mills are integrally designed, resulting in relatively low overall strength. This limits their ability to absorb stress during product machining, making them prone to resonance and affecting product quality. To address this, we propose a stable and vibration-damping ball end mill. Utility Model Content

[0004] The purpose of this invention is to provide a stable and vibration-damping ball end mill that absorbs machining load stress, thereby solving the problem that most existing ball end mills are integrally designed, have relatively low overall strength, and have limited absorption effect on load stress during product machining, which easily leads to resonance and affects the machining quality of the product.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stable and vibration-damping ball end mill, comprising a body and an alloy reinforcing post, wherein a reinforcing hole A is provided in the middle of the body, an alloy reinforcing post is installed inside the reinforcing hole A, an alloy reinforcing rod is installed at the bottom of the alloy reinforcing post, a reinforcing hole B is provided inside the body on the outer surface of the alloy reinforcing rod, and the alloy reinforcing rod is fitted inside the reinforcing hole B.

[0006] Preferably, the main body has a clamping groove in the middle of its bottom, and a spherical blade is installed inside the clamping groove by a locking screw.

[0007] Preferably, the main body has a spring groove located at the clamping slot position, a compression rod is installed inside the spring groove, a pressure ring is installed at the bottom of the compression rod, a spring is installed inside the spring groove at the top of the compression rod, and the spring groove is filled with damping rubber.

[0008] Preferably, the alloy reinforcing column and reinforcing hole A, and the alloy reinforcing rod and reinforcing hole B are all interference fit.

[0009] Preferably, the top of the main body is provided with a connecting hole, and a pressure plate is installed inside the connecting hole by a positioning screw, and a pull rod is installed inside the pressure plate.

[0010] Preferably, the tie rod is sleeved on the top of the alloy reinforcing column, and the tie rod and the alloy reinforcing column are connected by a threaded connection.

[0011] Preferably, the main body has a disassembly groove at the bottom of the connection hole, and the outer surface of the alloy reinforcing column has a slot near the top.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model achieves the effect of absorbing machining load stress by setting up a main body, reinforcing hole A, reinforcing hole B, alloy reinforcing rod and alloy reinforcing column. This solves the problem that most existing ball end mills adopt an integral setting, which has relatively low overall strength and limited effect on absorbing load stress during product processing. It is easy to generate resonance and affect the processing quality of the product. This invention reduces the probability of milling cutter resonance and thus improves the processing quality of milling cutter.

[0014] 2. This utility model achieves the effect of limiting and supporting the ball insert by setting a pressure ring, a compression rod, damping rubber and a spring, so as to solve the problem that the existing ball insert is prone to loosening after long-term use and clamping, which can easily lead to the vibration of the milling cutter. It reduces the vibration probability of the milling cutter and thus improves the machining quality of the milling cutter.

[0015] 3. This utility model achieves the effect of convenient removal of the alloy reinforcing column by setting up a pressure plate, tie rod, alloy reinforcing rod and alloy reinforcing column, so as to solve the problem that the existing milling cutter needs to be discarded as a whole after it is damaged, which wastes a lot of resources and affects the economic use of the milling cutter. It improves the reuse rate of the alloy reinforcing column, thereby improving the economic use of the milling cutter. Attached Figure Description
