[0002] In the production of miniature vacuum electronic devices, the quality of the machining of the microstructures on their tiny components directly affects their performance. Therefore, micro-milling cutters are often used to machine them, and micro-milling cutters are a type of milling cutter.

[0003] In the prior art, such as the single-edged micro milling cutter with chip removal groove disclosed in CN216881915U, a chip removal groove is provided on the lower side of the chip collection groove, and the chip collection groove is connected to the chip removal groove, which can clean up the waste chips generated by milling in a timely manner, avoid the accumulation of waste chips on the workpiece surface and cause secondary damage to the workpiece, and provide heat dissipation holes on the side of the cutter head near the cutting edge, which can dissipate heat from the cutter head and prevent high temperature from damaging it.

[0004] However, in implementing the relevant technology, it was found that the single-edged micro end mill with chip removal grooves has the following problems: Although the existing technology avoids chip accumulation by setting chip removal grooves and other components, in actual use, it only prevents chips from sticking to the machining points of the workpiece. Afterwards, the chips fly to the outer surface of the workpiece or even the worktable, requiring secondary cleaning. In view of this, a single-edged micro end mill with chip removal grooves is provided to overcome the above defects. Utility Model Content

[0005] This invention provides a single-edged micro-milling cutter with a chip removal groove to solve the problem of waste chips scattering onto the outer surface of the workpiece or even the operating table, requiring secondary cleaning.

[0006] The present invention achieves the above objectives through the following technical solution: a single-edged micro milling cutter with a chip removal groove, comprising a cutter bar, a cutter head fixed at the bottom end of the cutter bar, and a sliding groove formed on the outer wall of the cutter bar, wherein a cleaning mechanism is provided outside the sliding groove;

[0007] The cleaning mechanism includes a collar sleeved around the outside of the blade bar, with a connecting plate fixed to the bottom end of the collar. The connecting plate has a mounting groove inside, and a sliding block is slidably connected inside the mounting groove. A contact plate is fixed to the bottom end of the sliding block, and a brush is embedded in the bottom end of the contact plate. A support rod extends through the inside of the sliding block, and a spring is sleeved on the outside of one end of the support rod that extends through the sliding block.

[0008] As a further improvement of this utility model, the cleaning mechanism also includes a locking block, which is fixed at the position of the sliding groove on the outer wall of the collar, and a threaded sleeve is provided above the collar.

[0009] As a further improvement of this utility model: the collar and the tool holder form a sliding structure, and the tool holder is in close contact with the connecting plate.

[0010] As a further improvement of this utility model: the threaded sleeve is threadedly connected to the tool holder, and the threaded sleeve is tightly fitted to the collar.

[0011] As a further embodiment of this utility model: a storage mechanism is provided on one side of the contact plate, the storage mechanism includes a storage shell, the storage shell is disposed at one end of the contact plate, and a connecting block is embedded on one side of the outer wall of the storage shell, and a fastener is installed above the connecting block.

[0012] As a further improvement of this utility model: the storage mechanism also includes a storage groove, the outer wall of the storage shell is provided with a storage groove, and a guide block is provided on one side of the storage groove.

[0013] As a further improvement of this utility model: the storage shell is detachably connected to the connecting block, fasteners and the contact plate, and the storage shell is fixedly connected to the guide block by bolts.

[0014] The beneficial effects of this utility model are: the swivel groove allows the collar to be connected to the tool holder via the locking block, preventing the connecting plate from loosening during rotation, and the threaded sleeve is used to press it to prevent loosening. The connecting plate, through the cooperation of the mounting groove and the support rod, allows the sliding block to be pushed against the contact plate by the spring elasticity, allowing the brush to adhere to the workpiece. During processing, the brush sweeps away waste and pushes it outward, preventing accumulation and keeping the outer wall of the workpiece clean.

[0015] The connecting blocks and fasteners facilitate the disassembly and cleaning of the storage shell and the contact plate. The waste debris pushed by the brush passes through the collection groove and enters the storage shell along the guide block for unified collection, which facilitates unified cleaning later and avoids the need for secondary cleaning of waste debris. At the same time, the guide block prevents the waste debris from flowing back after entering. Attached Figure Description
