Description

Technical Field

[0001] This invention relates to the field of computer numerical control technology, and specifically to a detachable cleaning device and method for CNC milling machines. Background Technology

[0002] In the field of CNC milling, with the development of precision manufacturing technology, the requirements for workpiece machining accuracy are constantly increasing. However, the metal chips, dust, and other waste generated during the machining process have become key factors affecting machining quality and equipment lifespan. During milling, drilling, and other machining operations, waste will continuously accumulate on the worktable surface, workpiece clamping gaps, and equipment transmission areas. If it is not cleaned in a timely and effective manner, it will not only cause secondary friction between the tool and the workpiece, leading to increased machining dimensional errors, but may also cause jamming and wear of core transmission components such as guide rails and lead screws, significantly reducing the service life of the equipment. At the same time, the dust environment formed by the accumulation of waste will also have adverse effects on the workshop operating environment and the respiratory health of operators.

[0003] The existing technology still has the following technical defects: Although the traditional manual cleaning mode is flexible in operation, the sharp edges of metal shavings can easily cut the operator's hands, and the risk of dust inhalation is high, posing a significant safety hazard; while existing integrated cleaning devices mostly adopt a fixed installation structure, which cannot be disassembled according to the needs of milling machine maintenance and component replacement, resulting in cumbersome disassembly and assembly procedures during equipment maintenance and seriously affecting operation and maintenance efficiency; most existing cleaning devices' displacement mechanisms can only achieve movement in one direction, lacking the function of precise adjustment in both lateral and longitudinal directions; at the same time, the height and angle of the suction components are fixed, and cannot be flexibly adjusted according to the thickness and distribution of waste accumulation, resulting in poor cleaning effect on waste in different accumulation states and difficulty in achieving full coverage cleaning of the processing area. Summary of the Invention

[0004] The purpose of this invention is to provide a detachable cleaning device and method for CNC milling machines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a detachable cleaning device for a CNC milling machine, comprising a fixed frame:

[0006] The inner wall of the fixed frame is provided with an adapter mechanism for assisting installation, the inner wall of the fixed frame is provided with a locking mechanism for fastening installation, the inner side of the adapter mechanism is provided with a moving mechanism for displacement cleaning, and the lower part of the moving mechanism is provided with a suction mechanism for adjusting cleaning.

[0007] The locking mechanism includes a rotating component disposed on the back of the fixed frame and an elastic component connected to the rotating component. A sliding component and an insertion component connected to the sliding component are disposed on the outer side of the elastic component.

[0008] The moving mechanism includes an installation component disposed inside the fixed frame and a displacement component connected to the installation component. A support component is also disposed on the top of one side of the installation component.

[0009] The suction mechanism includes a pushing component disposed below the displacement component and a rotating component connected to the pushing component.

[0010] For example, the adapter mechanism includes a groove formed at the center of the surface of the fixed frame, a second sliding groove formed on both sides of the surface of the fixed frame, a first sliding groove formed at the end of the surface of the fixed frame, and a fixed seat fixedly installed at both ends of the back of the fixed frame.

[0011] For example, the rotating assembly includes a first motor fixedly mounted on the back of the fixed frame and a rotating block keyed to the output shaft of the first motor, the rotating block being located inside the groove.

[0012] For example, the elastic component includes a spring and a telescopic rod fixedly installed on the inner sidewall of the groove, with a vertical plate fixedly installed at the inner end of the spring and the telescopic rod, and the spring located on the outer side of the telescopic rod.

[0013] For example, the sliding assembly includes a connecting plate and a first slide bar fixedly installed on the outside of the vertical plate, the connecting plate and the first slide bar being fixedly connected, and the first slide bar sliding inside the second slide groove.

[0014] For example, the insertion assembly includes a fixing plate fixedly mounted on the outer end of the connecting plate, and an insertion block is fixedly mounted on the outer side of the fixing plate.

[0015] For example, the mounting assembly includes a second slide bar slidably connected inside the first slide groove and a mounting plate fixed to the inner side of the second slide bar;

[0016] The displacement assembly includes a first electric slide fixedly installed on the top of a mounting plate on one side and a second electric slide fixed to the top of the moving end of the first electric slide.

[0017] The support assembly includes a support plate fixedly installed on the top of the mounting plate on the other side and a slide rod fixed to the inner side of the support plate. A slide sleeve is slidably connected to the outer side of the slide rod, and the top of the slide sleeve is fixed to the second electric slide table.

[0018] For example, the pushing component includes a mounting frame fixedly mounted on the moving end of the second electric slide and an electric push rod fixed to the inner sidewall of the mounting frame, wherein a carrier plate is fixedly mounted on the output end of the electric push rod.

[0019] For example, the rotating assembly includes a second motor fixedly mounted on the top of the carrier plate and a suction head keyed to the output shaft of the second motor, the discharge end of the suction head being connected to a flexible hose.

[0020] A method, applied to the aforementioned removable cleaning device for a CNC milling machine, includes the following steps:

[0021] Step 1: Adapt to the installation steps. Align the fixed frame with the preset installation position on the CNC milling machine worktable. Use the fixed seat to achieve the initial positioning of the fixed frame and the milling machine worktable to ensure the stability of the subsequent mechanism installation reference. Then, align the second slide bar with the first slide groove and insert it into it to complete the pre-connection installation.

[0022] Step 2, Locking Installation Step: Start the first motor. The first motor drives the rotating block to rotate and contact the vertical plate. The vertical plate compresses the spring and drives the telescopic rod to retract, thereby pushing the connecting plate and the first slide bar to slide along the second slide groove, so that the insert block on the outside of the fixed plate is inserted into the preset locking hole of the CNC milling machine worktable, completing the fastening and locking of the fixed frame and the milling machine.

[0023] Step 3: Move the cleaning position. Based on the distribution of waste in the milling machine processing area, start the first electric slide to drive the second electric slide to move laterally. The slide rod and slide sleeve on the inner side of the support plate cooperate to guide the second electric slide to drive the suction mechanism below to move precisely above the area to be cleaned.

[0024] Step 4, suction adjustment step: start the electric push rod and push the carrier plate to move up and down along the mounting frame, adjust the vertical distance between the suction head and the milling machine surface, then start the second motor, the second motor drives the suction head to rotate, adjust the suction angle of the suction head so that the suction head fits the waste accumulation area.

[0025] Step 5, waste removal step: Connect the negative pressure air source of the suction head, and use the suction head to adsorb metal shavings and dust generated by CNC milling. The adsorbed waste is transported to the preset collection device through the hose connected to the discharge end of the suction head. At the same time, the suction head is moved to full coverage by the first electric slide and the second electric slide to achieve a complete cleaning of the processing area.

[0026] Step six, disassembly and storage steps: After cleaning, turn off the negative pressure air source and all drive components, start the first motor in reverse, the rotating block resets, the spring elastically rebounds and drives the insert block to disengage from the milling machine locking hole, the locking state is released, and the structure can be separated and installed along the first slide groove.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. This invention solves the pain points of existing integrated cleaning devices that cannot be disassembled and have complicated maintenance procedures by using the coordinated design of the adaptation mechanism and the locking mechanism, the installation method of initial positioning by the fixed seat, locking by the first motor driving the plug, and the disassembly logic of unlocking and separating by reversing the motor. It achieves precise adaptation of the device to CNC milling machines of different specifications and improves the efficiency of installation and disassembly.

[0029] 2. This invention utilizes the lateral and longitudinal coordinated displacement of the first and second electric slides through a moving mechanism, combined with the guiding support of the slide rod and slide sleeve, to achieve precise positioning of the suction mechanism. The suction mechanism adjusts its height via an electric push rod and rotates and adjusts its angle by driving the suction head with a second motor, making it adaptable to waste accumulation scenarios of different thicknesses and distribution patterns. This achieves full coverage cleaning of the processing area without any dead angles, resulting in improved cleaning coverage compared to traditional devices with single-direction displacement and fixed suction angles.

[0030] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention can be realized and obtained by means of the structures pointed out in the description and the drawings. Attached Figure Description

[0062] Align the fixed frame 1 with the preset installation position on the CNC milling machine worktable, and complete the initial positioning with the help of the fixed base 24. The second slide bar 41 is pre-slidably located inside the first slide groove 21. Then, take out the second slide bar 41, align it with the first slide groove 21, and insert it into it to complete the pre-installation connection. Start the first motor 31. The first motor 31 drives the rotating block 32 to rotate and abut against the vertical plate 35.

The slide rod 45 on the inner side of the support plate 44 cooperates with the slide sleeve 46 to guide the second electric slide 47 to drive the suction mechanism 5 below to move precisely above the area to be cleaned.

[0070] Step 4, suction adjustment step: start the electric push rod 52 and push the carrier plate 53 to move up and down along the mounting frame 51, adjust the vertical distance between the suction head 55 and the milling machine surface, then start the second motor 54, the second motor 54 drives the suction head 55 to rotate, adjust the suction angle of the suction head 55 so that the suction head 55 fits the waste accumulation area.

[0071] Step 5, waste removal step: Connect the negative pressure air source of the suction head 55, and use the suction head 55 to adsorb metal shavings and dust generated by CNC milling. The adsorbed waste is transported to the preset collection device through the hose 56 connected to the discharge end of the suction head 55. At the same time, the suction head 55 is moved to full coverage by the first electric slide table 43 and the second electric slide table 47 to achieve comprehensive cleaning of the processing area.
