Description

Technical Field

[0001] This utility model relates to the field of CNC machining equipment technology, and in particular to a CNC dust collection device. Background Technology

[0002] CNC, or Computer Numerical Control, is an important tool in modern manufacturing. It uses computer programs to precisely control the movement and machining operations of machine tools. CNC can achieve high-precision machining of complex-shaped parts, and is characterized by high efficiency, high consistency, and high flexibility. It is widely used in many fields such as aerospace, automotive, mold making, and electronics. For example, in aero-engine manufacturing, CNC can machine high-precision blades; in mold making, it can create precise cavities. The continuous development of CNC technology has promoted the automation and intelligentization of manufacturing, improved product quality and production efficiency, and reduced labor costs and errors.

[0003] Existing technologies, such as the utility model patent with publication number CN220312688U, disclose a dust collection device during CNC machining of composite materials. This patent uses a cover installed on the outside of the CNC spindle, with a duct connected to the side of the cover; it also includes: a fixing seat, fixedly installed on the inside of the cover, with a dust-blocking brush on the outside of the fixing seat; a dust collection pipe, integrally set at the lower end of the cover, with a telescopic sleeve movably connected to the outside of the lower end of the cover, and a return spring sleeved on the outside of the dust collection pipe; the cover is sleeved with the CNC spindle, and the axial direction of the upper inner side of the cover is equiangular. The device is equipped with spring steel balls that engage with the CNC spindle. An O-shaped rubber ring is embedded in the inner wall of the housing. This dust collection device for CNC machining of composite materials can be easily mounted on the outside of the CNC spindle to cover the tool, allowing for comprehensive dust collection at the tool's working area. It is suitable for machining various curved surfaces, addressing the problem that some existing dust collection devices have limited suction range due to the suction pipe being located outside the tool head, resulting in insufficient dust collection and other defects.

[0004] In the process of using a vacuum cleaner to process waste, existing vacuum cleaners, such as the one described above, separate the installation chamber and the suction chamber with a dust-blocking brush, and install the suction pipe on the outside of the casing. When the vacuum cleaner is in operation, because the installation chamber and the suction chamber are in a connected state, the space inside the casing is relatively large. This causes the suction pipe to be affected by the internal space of the casing, resulting in a decrease in the suction power generated by the suction pipe. Furthermore, when the suction power of the suction pipe is insufficient, some debris will accumulate in the adsorption space formed by the casing and will be difficult to be sucked away by the suction pipe in time, thereby interfering with the normal operation of the cutting tool. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the suction power of the suction pipe is reduced due to the influence of the internal space of the casing during operation, and when the suction power of the suction pipe is insufficient, some debris will accumulate in the adsorption space formed by the casing and be difficult to be sucked away by the suction pipe in time, thereby interfering with the normal operation of the cutting tool. Therefore, a CNC dust collection device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a CNC dust collection device, comprising a rotating shaft, a cutting tool, and an auxiliary component, wherein the cutting tool is mounted on the lower surface of the rotating shaft, and the auxiliary component is disposed on the surface of the rotating shaft;

[0007] The auxiliary components include an assembly unit, which includes a T-shaped sleeve. The T-shaped sleeve is fitted onto the surface of the rotating shaft. The surface of the T-shaped sleeve has an insertion hole. A fixing bolt is installed on the inner wall of the T-shaped sleeve at the insertion hole. The surface of the rotating shaft has a threaded groove. The fixing bolt is threadedly connected to the inner wall of the threaded groove. A connecting sleeve is fixedly connected to the lower surface of the T-shaped sleeve. A guide frame is fixedly connected to the surface of the connecting sleeve. A compression spring is fixedly connected to the lower surface of the T-shaped sleeve.

[0008] The auxiliary components also include a shielding unit, which includes a force-carrying ring that is slidably connected to the inner wall of the guide frame. The force-carrying ring is fixedly connected to the lower surface of the compression spring. A shield is fixedly connected to the lower surface of the force-carrying ring. A dust suction connector is fixedly connected to the outer circumference of the shield. A sealing disc is fixedly connected to the inner wall of the force-carrying ring. Brush bristles are fixedly connected to the inner wall of the sealing disc. A cover plate is fixedly connected to the upper surface of the sealing disc. The cover plate fits onto the surface of the blade. A U-shaped groove is provided on the arc surface of the connecting sleeve. The U-shaped groove is adapted to the diameter of the dust suction connector.

[0009] Preferably, there are three fixing bolts arranged in a circumferential array about the T-shaped sleeve. The T-shaped sleeve can be stably installed on the rotating shaft by the fixing bolts, thereby ensuring the stability of the T-shaped sleeve in the working state.

[0010] Preferably, there are four guide frames arranged in a circular array about the connecting sleeve. The guide frames can guide the movement direction of the load-bearing ring to ensure the stability of the load-bearing ring in the moving state.

[0011] Preferably, the compression spring is located on the inner wall of the connecting sleeve. The compression spring can constrain the position of the load ring to ensure the stability of the load ring during operation.

[0012] Preferably, the load-bearing ring is slidably connected to the inner wall of the connecting sleeve. The load-bearing ring can support and restrict the position of the connecting sleeve, thereby ensuring that the connecting sleeve can shield the tool.

[0013] Preferably, the shield is fitted onto the surface of the blade, and the vacuum connector is connected to the inner wall of the shield. The vacuum connector allows the user to install a vacuum hose, thereby ensuring that the vacuum hose can assist the vacuum connector in vacuuming operations.

[0014] Preferably, the brush is in contact with the surface of the tool, and the brush can be used to initially clean the debris attached to the surface of the tool when the tool is working.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, by setting auxiliary components, before the equipment operates, a T-shaped sleeve is fitted onto the surface of the rotating shaft, and a fixing bolt is tightened. The fixing bolt, in conjunction with the T-shaped sleeve, allows the remaining auxiliary component structures to be installed on the rotating shaft surface. Simultaneously, the dust suction pipe of the dust collection mechanism is fixed to the dust suction connector, thus completing the overall installation of the auxiliary components. When the equipment operates, the rotating shaft, in conjunction with the T-shaped sleeve, pushes the connecting sleeve. Under the action of a compression spring, the connecting sleeve pushes the load-bearing ring, which in turn pushes the shielding cover against the workpiece surface. When the cutting tool performs cutting, the shielding cover engages with the tightening mechanism... The sealing disc blocks the chips generated by the cutting tool, confining them to a small area. The blocked chips are then sucked away from the machining area by the suction connector and suction mechanism. When the shaft pulls the tool back to its original position, the tool gradually passes through the brush bristles, which clean the chips off the tool surface. By incorporating auxiliary components, the suction chamber of the device is reduced in size, increasing the suction power and mitigating the problem of reduced suction power caused by an excessively large suction chamber. This further improves the stability of the suction device. Attached Figure Description

Brush bristles 325 are fixedly connected to the inner wall of the sealing disc 324. A cover plate 326 is fixedly connected to the upper surface of the sealing disc 324. The cover plate 326 is sleeved with the surface of the cutter 2. A U-shaped groove 327 is provided on the arc surface of the connecting sleeve 314. The U-shaped groove 327 is adapted to the diameter of the dust suction connector 323.

[0027] Specifically, there are three fixing bolts 313, which are arranged in a circumferential array about the T-shaped sleeve 311. The T-shaped sleeve 311 can be stably installed on the rotating shaft 1 by fixing bolts 313, thereby ensuring the stability of the T-shaped sleeve 311 in the working state.

[0028] Specifically, there are four guide frames 315, which are arranged in a circular array about the connecting sleeve 314.

[0029] In this embodiment, the guide frame 315 can guide the movement direction of the load ring 321 to ensure the stability of the load ring 321 in the moving state.

[0030] Specifically, the compression spring 316 is located on the inner wall of the connecting sleeve 314. The position of the load ring 321 can be constrained by the compression spring 316 to ensure the stability of the load ring 321 in operation.

[0032] In this embodiment, the position of the connecting sleeve 314 can be supported and restricted by the load-bearing ring 321, thereby ensuring that the connecting sleeve 314 can shield the tool 2.

[0033] Specifically, the shield 322 is fitted onto the surface of the blade 2, and the vacuum connector 323 is connected to the inner wall of the shield 322.

The fixing bolt 313, in conjunction with the T-shaped sleeve 311, allows the remaining auxiliary components 3 to be installed on the surface of the rotating shaft 1. Simultaneously, the dust suction pipe of the dust suction mechanism is fixed to the dust suction connector 323 to complete the overall installation of the auxiliary components 3. When the equipment is working, the rotating shaft 1, in conjunction with the T-shaped sleeve 311, pushes the connecting sleeve 314. Under the action of the compression spring 316, the connecting sleeve 314 pushes the load-bearing ring 321. The load-bearing ring 321 pushes the shield 322 against the workpiece surface. When the tool 2 performs cutting, the shield... The baffle 322, in conjunction with the sealing disc 324, shields the chips generated by the cutting tool 2, confining them to a small area. The shielded chips are then sucked away from the processing area by the suction connector 323 and the suction mechanism. When the rotating shaft 1 pulls the tool 2 back to its original position, the tool 2 gradually passes through the brush 325, which cleans the chips from the surface of the tool 2. By setting the auxiliary component 3, the suction chamber of the device is reduced in size, and the suction power of the device is increased. This reduces the problem of reduced suction power caused by an excessively large suction chamber and further improves the stability of the suction device.
