Description

Technical Field

[0001] This utility model relates to a single-flute micro end mill, specifically a single-flute micro end mill that facilitates heat dissipation and chip removal, belonging to the field of end mill technology. Background Technology

[0002] In high-end fields such as radar, communications, detection, electronic countermeasures navigation, computer terminal display, automatic control, and medical diagnosis and treatment, including aerospace, biomedicine, and space communications, complex, high-precision, high aspect ratio micro-components are increasingly widely used. The microstructure machining quality of these micro-components directly affects their performance. Currently, single-flute micro-milling cutters, a type of milling cutter, are commonly used for machining these micro-components.

[0003] In the prior art, such as the single-flute micro milling cutter with a polygonal straight-edged head disclosed in CN216881918U, the present invention, during milling, injects coolant into the water inlet hole, allowing the coolant to flow through the coolant tank and then out from the water outlet hole, thereby removing heat from the cutter head and the surface of the straight cutting edge, preventing high temperature from damaging the straight cutting edge and electronic components. Moreover, during processing, the centering of the cutter head end face is fixedly set, which enables rapid positioning of the workpiece and improves milling efficiency.

[0004] However, in implementing the relevant technology, it was found that the single-flute micro end mill with a polygonal straight-edged head as described above has the following problems: In the prior art, heat dissipation is achieved by cooling with coolant water. However, in actual use, when machining some workpieces for electronic components, the coolant may affect the electronic components, resulting in limitations. In view of this, a single-flute micro end mill that facilitates heat dissipation and chip removal is provided to overcome the above defects. Utility Model Content

[0005] This invention addresses the technical problem of coolant potentially affecting electronic components during machining, leading to limitations in processing technology. It provides a single-edged micro-milling cutter that facilitates heat dissipation and chip removal.

[0006] The present invention achieves the above objectives through the following technical solution: a single-edged micro milling cutter that facilitates heat dissipation and chip removal, comprising a connecting cylinder, a cutter shank extending from the bottom end of the connecting cylinder, and a cutter head fixed below the cutter shank, and a cooling mechanism provided on the outside of the connecting cylinder;

[0007] The cooling mechanism includes a battery assembly, which is fixed to the outer wall of the connecting cylinder and has a charging port on its outer wall. A cooling plate is provided below the battery assembly. A limit block is fixed to one end of the blade extending out of the connecting cylinder, and a locking block is provided on the outside of the limit block.

[0008] As a further improvement of this utility model: the battery assembly further includes a limiting ring, which is fixed to the outer wall of the end of the knife bar located outside the connecting cylinder, and an installation sleeve is fitted on the outside of the limiting ring.

[0009] As a further improvement of this utility model: the cooling plate is closely fitted with the card block, and the card block and the limiting block form a sliding structure.

[0010] As a further improvement of this utility model: a positioning block is fixed on the two axially opposite surfaces of the card block, and a positioning groove is opened on the outer wall of the limiting block corresponding to the position of the positioning block.

[0011] As a further improvement of this utility model: the limiting block is provided with a ventilation mechanism, the ventilation mechanism includes a guide groove, the guide groove is opened below the external cooling plate of the connecting cylinder, and the guide groove is provided with a flow port inside.

[0012] As a further improvement of this utility model: the ventilation mechanism further includes a flow cavity, which is opened inside the limiting block, and the outer wall of the cutter head is provided with a flow hole.

[0013] As a further improvement of this utility model: the flow port is connected to the flow cavity, and the flow cavity is connected to the flow hole.

[0014] The beneficial effects of this utility model are as follows: When the cutter bar is inserted into the connecting cylinder, it is prevented from shifting by sliding along the positioning groove through the positioning block. The locking block initially limits the positioning of the limiting block, and the mounting sleeve abuts against the limiting ring and the threaded connection of the connecting cylinder, thus enabling quick disassembly and replacement if problems occur. The battery assembly provides power to the cooling plate, which cools the locking block that is in contact with the cold end of the cooling plate and transfers the temperature to the limiting block, thereby reducing the temperature of the cutter bar and the cutter head and achieving a cooling and heat dissipation effect. When the connecting cylinder rotates, the gas enters the flow port through the guide groove and enters the interior of the connecting cylinder. It then enters the limiting block through the flow cavity and finally exits through the flow hole, which can drive the circulation of cold air and improve the heat dissipation effect.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] like Figures 1 to 4 As shown, a single-edged micro-milling cutter for easy heat dissipation and chip removal includes a connecting cylinder 1, a cutter shank 2 extending from the bottom end of the connecting cylinder 1, a cutter head 3 fixed below the cutter shank 2, and a cooling mechanism 4 disposed on the outside of the connecting cylinder 1. The cooling mechanism 4 includes a battery assembly 401 fixed to the outer wall of the connecting cylinder 1, a charging port 402 opening on the outer wall of the battery assembly 401, a cooling plate 403 disposed below the battery assembly 401, a limiting block 404 fixed to one end of the cutter shank 2 extending from the connecting cylinder 1, a locking block 405 disposed on the outside of the limiting block 404, and a limiting ring 406 fixed to the outer wall of the end of the cutter shank 2 located outside the connecting cylinder 1, with an mounting sleeve 407 sleeved on the outside of the limiting ring 406. Plate 403 and locking block 405 fit tightly together. Locking block 405 and limiting block 404 form a sliding structure. Positioning blocks 5 are fixed on the two axially opposite surfaces of locking block 405. Positioning grooves 6 are opened on the outer wall of limiting block 404 corresponding to the positions of positioning blocks 5. When the tool bar 2 is inserted into the connecting cylinder 1, it slides along the positioning grooves 6 through positioning blocks 5 to avoid displacement. The locking block 405 initially limits the limiting block 404 and cooperates with the mounting sleeve 407 to abut against the limiting ring 406 and the threaded connection of the connecting cylinder 1, so that it can be quickly disassembled and replaced when problems occur. The battery assembly 401 provides power to the cooling plate 403, so that the locking block 405 with the cold end of the cooling plate 403 can be cooled down and transferred to the limiting block 404, reducing the temperature of the tool bar 2 and the tool head 3 to achieve a cooling and heat dissipation effect. Example 2

[0022] In addition to all the technical features in Embodiment 1, this embodiment also includes: a ventilation mechanism 7 is provided inside the limiting block 404. The ventilation mechanism 7 includes a guide groove 701, which is located below the cooling plate 403 outside the connecting cylinder 1. A flow port 702 is provided inside the guide groove 701. The ventilation mechanism 7 also includes a flow cavity 703, which is located inside the limiting block 404. A flow hole 704 is provided on the outer wall of the cutter head 3. The flow port 702 communicates with the flow cavity 703, and the flow cavity 703 communicates with the flow hole 704. When the connecting cylinder 1 rotates, the gas enters the flow port 702 through the guide groove 701 and enters the interior of the connecting cylinder 1. It then enters the limiting block 404 through the flow cavity 703 and is finally discharged through the flow hole 704, which can drive the circulation of cold air and improve the heat dissipation effect.

[0023] Working principle: The connecting sleeve 1 is used to connect with machine tools and other equipment. The tool bar 2 and the tool head 3 are integrated. The tool bar 2 is inserted into the connecting sleeve 1 and is connected to the connecting sleeve 1 by thread through the mounting sleeve 407 against the limiting ring 406, which facilitates quick disassembly and replacement. The tool head 3 is equipped with a chip removal groove for chip removal. The connecting sleeve 1 limits the limiting block 404 through the internal fixed locking block 405, thereby limiting the tool bar 2 and increasing the torque bearing capacity during rotation. At the same time, it works with the positioning block 5 and the positioning groove 6 to prevent displacement during sliding disassembly and assembly. The battery assembly 401 is equipped with matching electronic components to open and close the cooling plate 403. The charging port 402 can charge the battery assembly 401. The cold end of the cooling plate 403 is attached to the locking block 405, which achieves heat dissipation through transmission. With the flow port 702 opened in the guide groove 701, air enters when the tool bar 2 rotates, flows through the flow cavity 703 and flows out through the flow hole 704, thereby driving the circulation of cold air and improving the heat dissipation effect.
