Description

Technical Field

[0001] This utility model relates to the field of tool chip removal technology, and in particular to a tool chip removal groove structure. Background Technology

[0002] Chip evacuation grooves are special structures designed on cutting tools. Their main function is to help effectively remove chips, ensuring that chips can be discharged smoothly, thereby avoiding chip entanglement and blockage, and ensuring the smooth progress of the machining process. Chip evacuation grooves are usually designed on the rake face of the cutting tool, and their shape and size have a direct impact on the chip discharge effect.

[0003] Existing technology, with publication number CN208961071U, discloses a chip removal structure for machining difficult-to-break materials. This tool has an insert at the head and a tool shank at the rear. The tool has an internal cooling hole that extends through both ends of the tool along its axial direction. The tool also has an external drainage groove. When the tool leaves the workpiece, the external drainage groove flushes away the chips trapped on the tool. The external drainage groove includes a radial through-slot extending radially through the rear end face of the tool shank and an axial groove extending axially along the outer wall of the tool. The radial through-slot communicates with the rear end of the internal cooling hole, and the rear end of the axial groove communicates with the radial through-slot. The technical solution adopted in this invention is that during machining, the internal cooling hole in the middle provides internal cooling while simultaneously removing chips. When the tool leaves the workpiece, the external drainage groove flushes away the chips trapped on the tool, thus solving the problem of chips affecting continuous machining.

[0004] When workers need to remove chips from the cutting tool, they install chip removal grooves on the machining components to guide the metal chips out. However, in the existing chip removal groove structure, metal chips may get stuck or stick to the groove during use, causing the cutting tool to drive the metal chips to rub against the workpiece, which in turn causes scratches on the surface of the workpiece.

A support sleeve 33 is fixedly connected to the outer side of the component holder 2. A drive motor 31 is fixedly connected inside the support sleeve 33. A fan blade 32 is fixedly connected to the drive end of the drive motor 31. The fan blade 32 is located inside the support sleeve 33. A connecting rod 36 is threadedly connected to the bottom end of the support sleeve 33. The connecting rod 36 is inserted into the interior of the component holder 2. An air inlet 34 is provided at the top end of the processing component 1. An air chamber 35 is provided inside the processing component 1. The air inlet 34 communicates with the air chamber 35. The air blowing hole 38 communicates with the air chamber 35. A limiting plate 37 is fixedly connected to the bottom end of the support sleeve 33. The limiting plate 37 is located on one side of the connecting rod 36. The limiting plate 37 can cooperate with the support sleeve 33 to limit the connecting rod 36. A blocking device 4 is provided at the top end of the processing component 1. The blocking device 4 includes a threaded ring 43, which is threadedly connected to the top end of the processing component 1.

[0023] In this embodiment, the threaded ring 43 can cooperate with the processing component 1 to support the extrusion rod 44.

[0024] In this embodiment: the inner side of the threaded ring 43 is threaded with a pressing rod 44, which is located inside the air cavity 35. The pressing rod 44 can cooperate with the threaded ring 43 to guide the extension of the pressing rod 44.

[0025] Specifically, a filter screen 41 is placed inside the air chamber 35, and the squeeze rod 44 is inserted into the top of the filter screen 41.

[0026] In this embodiment, the filter screen 41 can be used in conjunction with the air chamber 35 to prevent metal shavings from entering.

[0027] Specifically, the outer surface of the filter screen 41 is provided with air holes 42, and some of the air holes 42 are aligned with the air blowing holes 38.

[0028] In this embodiment, the air vent 42 can be used in conjunction with the filter screen 41 to achieve the purpose of air discharge.

[0029] Working principle: By setting up the chip removal device 3, when the worker needs to remove metal chips from the inside of the discharge trough 5, the drive motor 31 is started. The drive motor 31 drives the fan blade 32, which rotates and pushes air into the connecting rod 36. The connecting rod 36 guides the air to the air inlet 34, which in turn guides the air into the air chamber 35. Once the air chamber 35 is full, it is discharged through the air blowing hole 38. The air blows out the metal chips stuck or adhering to the inside of the discharge trough 5. By setting up the chip removal device 3, metal chips inside the discharge trough 5 can be effectively removed, avoiding friction between the cutting tool and the workpiece caused by metal chips during operation, thereby reducing scratches on the surface of the workpiece.

When the interior of the filter screen 41 is filled with air, the unblocked air vents 42 guide the air to blow towards the air vents 38. By setting the blocking device 4, metal shavings can be effectively blocked, preventing them from entering the air chamber 35 and affecting the gas flow, thereby improving the chip removal effect of the chip removal device 3.
