Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing tools, in particular to a thread milling cutter free of primer holes. Background Art

[0002] Traditional thread machining methods primarily involve turning threads with thread turning tools or manually tapping and threading with taps and dies. The development of CNC machining technology, particularly the advent of three-axis CNC machining systems, has enabled the implementation of a more advanced thread machining method: CNC milling. Compared to traditional thread machining methods, thread milling offers significant advantages in precision and efficiency, and is not restricted by thread structure or thread spin. For example, a single thread milling cutter can process internal and external threads with a variety of spins. Threads that do not allow for transition buckles or undercuts are difficult to machine using traditional turning methods or taps and dies, but are easily achievable using CNC milling. Furthermore, thread milling cutters are more than ten or even dozens of times more durable than taps, and the thread diameter can be easily adjusted during CNC milling, something difficult to achieve using taps and dies. Due to the many advantages of thread milling, milling has become a widely used process for large-scale thread production in developed countries.

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

Figure 3 This utility model Figure 2 The structural cross-sectional view of line AA, Figure 4 It is a structural schematic diagram of the clamp α of the present utility model.

[0019] The utility model provides a thread milling cutter without base hole drilling, comprising a tool handle 1, a tool body 2, a storage box 3, a chip groove 201, milling teeth 202, a drill tip 203, an output pipe 4, a pressure chamber 5, a nozzle 6, a receiving pipe 7 and a spraying pipe 8. The above solution solves the problem that each time a workpiece is processed, it is necessary to use an external object to pre-drill a hole in the workpiece before it can be processed, which affects the processing efficiency.

[0020] According to this specific embodiment, the cutter body 2 has two chip grooves 201, two groups of milling teeth 202 and a drill tip 203. The cutter body 2 is fixedly connected to the tool handle 1 and is located at one end of the cutter body 2. The two chip grooves 201 are distributed circumferentially along the axial center line of the cutter body 2. The two groups of milling teeth 202 are staggered along the circumference of the axial center line of the cutter body 2. The milling teeth 202 are fixedly connected to the cutter body 2 and are located on the outer surface of the cutter body 2. The drill tip 203 is fixedly connected to the cutter body 2 and is located at one end of the cutter body 2. The length of the drill tip 203 is 3 mm. The storage box 3 is fixedly connected to the tool handle 1 and is located at one end of the tool handle 1. The cooling components are fixedly connected to the tool handle 1 and the cutter body 2 and are located at one end of the tool handle 1 and the cutter body 2. The other end of the cooling component is fixedly connected to the storage box 3 and is located at one end of the storage box 3. The tool handle 1 is fixed to the bottom of the machine tool. The diameter of the tool handle 1 is 10 mm, the outer circle size of the thread of the cutter body is 8.2 mm, the length of the cutter body is 24 mm, the diameter of the drill tip is 8.5 mm, and the length of the bottom hole-free thread milling cutter is 75 mm. The workpiece is drilled by the set drill tip 203, thereby eliminating the need for drilling. The workpiece is milled by the two groups of milling teeth 202, which can effectively improve the milling accuracy and efficiency. The two drainage grooves effectively prevent debris from adhering to the cutter body 2. Coolant is added to the storage box 3 in advance, and the coolant in the storage box 3 is transported to the cutter body 2 through the cooling component to reduce the temperature generated during the milling process.

[0021] Among them, there is a center line between each group of milling teeth 202, and the milling teeth 202 form an angle α with the center line, and the angle α is 30°. The tooth pitch of the milling teeth 202 is 1.5 mm, and the angle α is 30°, which makes the stability between the two milling teeth 202 better and facilitates the continuous operation of the milling cutter.

[0022] Secondly, the cooling component includes an injection pipe and a pipeline. The injection pipe is fixedly connected to the storage box 3 and is located at one end of the storage box 3. The pipeline is fixedly connected to the injection pipe and is located at one end of the injection pipe. The coolant in the storage box 3 is transported to the pipeline through the injection pipe and then sprayed out through the pipeline.

[0023] At the same time, the injection pipe includes an output pipe 4, a pressure chamber 5 and a nozzle 6. The pressure chamber 5 is fixedly connected to the output pipe 4 and is located at one end of the output pipe 4. The nozzle 6 is fixedly connected to the pressure chamber 5 and is located at one end of the pressure chamber 5. The coolant enters the output pipe 4 and the pressure of the coolant is increased by the pressure chamber 5. Since the pressure chamber 5 is affected by the pressure, the coolant is sprayed out through the nozzle 6.

[0024] In addition, the pipeline includes a receiving tube 7 and a spraying tube 8. The receiving tube 7 is fixedly connected to the nozzle 6 and is located at one end of the nozzle 6. The spraying tube 8 is fixedly connected to the receiving tube 7 and is located at one end of the receiving tube 7. The nozzle 6 sprays the coolant into the receiving tube 7, and the receiving tube 7 sprays the coolant out through the spraying tube 8.

[0025] A bottom hole-free thread milling cutter according to the present embodiment is used. When it is used, the tool holder 1 is fixed to the bottom of the machine tool, and the workpiece is drilled by the provided drill tip 203, thereby eliminating the need for drilling. The workpiece is milled by the two groups of milling teeth 202, which can effectively improve the accuracy and efficiency of milling. The two discharge grooves effectively prevent debris from adhering to the cutter body 2. The angle α is 30°, which makes the stability between the two milling teeth 202 better and facilitates the continuous operation of the milling cutter. Coolant is added to the storage box 3 in advance. During processing, the coolant enters the output pipe 4 and the pressure of the coolant is increased through the pressure chamber 5. Since the pressure chamber 5 is affected by the pressure, the nozzle 6 sprays the coolant into the receiving pipe 7, and the receiving pipe 7 sprays the coolant through the spray pipe 8, so that it can be cooled quickly and the processing efficiency is improved.
