Description

Technical Field

[0001] This utility model relates to the field of CNC milling machine technology, specifically to a chip cleaning device for CNC milling machines. Background Technology

[0002] The full name of a CNC milling machine is "numerical control milling machine," abbreviated as CNC milling machine in English. Its core function is to replace traditional manual operation, automatically completing the movement, rotation, and cutting actions of the milling cutter according to a pre-programmed program, and ultimately processing the raw material into parts that meet the design requirements.

[0003] Currently, during CNC milling machine processing, a large amount of metal or non-metal debris is easily generated. If this debris is not cleaned in time, it will continue to accumulate on the machining table and around key moving parts such as guide rails and lead screws, not only causing clutter in the work area but also seriously affecting machining accuracy and equipment lifespan. Traditionally, this cleaning work is highly dependent on manual labor, requiring operators to frequently stop the machine and use manual tools to clean each piece individually. This not only results in long cleaning cycles and low efficiency but also increases the physical burden on workers and the safety risks associated with contact with sharp debris.

[0016] 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.

[0017] Please see Figures 1-5 This utility model provides a technical solution: Example 1: Please see Figures 1-5 A chip removal device for a CNC milling machine includes a frame 1, a milling device 2, a worktable 3, and a tilting device 4. The milling device 2 is mounted on the frame 1 and is used to mill raw materials. The worktable 3 is located below the milling device 2 and is used to place raw materials. The tilting device 4 includes a drive shaft 41, a housing 42, a worm gear 43, a worm 44, and a tilting motor 45. The drive shaft 41 is rotatably connected to the frame 1, the housing 42 is fixedly connected to the frame 1, the drive shaft 41 is fixedly connected to the worktable 3, the worm gear 43 is fixedly connected to the drive shaft 41, the worm 44 and the worm gear 43 are both rotatably connected inside the housing 42, and the worm 44 meshes with the worm gear 43. The tilting motor 45 is fixedly connected to the housing 42, and the output end of the tilting motor 45 is connected to the worm gear. 44 Fixed connection; During processing, the raw material is placed on the worktable 3, and the milling device 2 performs the milling operation; After processing, the tilting motor 45 is started, which drives the worm gear 44 to rotate, drives the worm wheel 43 and the drive shaft 41 to rotate, thereby causing the worktable 3 to tilt around the drive shaft 41. The debris falls off automatically under the action of gravity, completing the debris cleaning work; The tilting device 4 utilizes the self-locking characteristic of the worm wheel 43 and worm gear 44 transmission to enable the worktable 3 to be reliably locked at any tilting angle, making it difficult for the worktable 3 to be accidentally deflected due to external force or vibration during operation. While realizing automatic debris cleaning and improving work efficiency, it further ensures the safety of operation and solves the problems of low efficiency and safety risks of manual cleaning.

[0018] Please see Figure 1 and Figures 3-5 A positioning device 5 is installed on the frame 1 to position the worktable 3. The positioning device 5 includes an electric push rod 51, a positioning plate 52, and a pin 53. The electric push rod 51 is fixedly connected to the frame 1, the positioning plate 52 is fixedly connected to the worktable 3, and the output end of the electric push rod 51 is fixedly connected to the pin 53. The positioning plate 52 has a hole 54 for the pin 53. During the machining process, the electric push rod 51 pushes the pin 53 into the hole 54 of the positioning plate 52, locking the worktable 3 in the machining position. After the machining is completed, the electric push rod 51 retracts, causing the pin 53 to disengage from the hole 54, releasing the positioning for subsequent flipping and cleaning. This positioning device 5 achieves precise positioning and rigid fixation of the worktable 3 during milling through electromechanical interlocking, suppressing possible vibrations and displacements during the machining process. This ensures the machining accuracy of the parts and provides a prerequisite for safe flipping and cleaning.

[0019] Please see Figure 1 and Figures 3-5 A wedge-shaped surface 55 is formed between the side of the pin 53 and the end face near the insertion hole 54. When the electric push rod 51 pushes the pin 53 to move, the wedge-shaped surface 55 at its end first contacts the edge of the insertion hole 54 of the positioning plate 52. Through the guiding and squeezing action of the inclined surface, the slight positional deviation between the pin 53 and the insertion hole 54 is automatically corrected, and the worktable 3 is driven to make fine adjustments until the pin 53 is fully embedded in the insertion hole 54. This wedge-shaped surface 55 structure realizes the automatic centering and smooth insertion of the pin 53, overcomes the positioning jamming problem caused by processing errors or vibration, and improves the operational reliability and service life of the positioning device 5.

[0020] Please see Figure 1 and Figures 3-5 Several positioning devices 5 are arranged in a rectangular array around the worktable 3. When the worktable 3 needs to be locked, the multiple positioning devices 5 arranged in a rectangular array around it act synchronously. Each electric push rod 51 pushes the pin 53 with a wedge-shaped surface 55 and accurately inserts it into the corresponding positioning plate 52's insertion hole 54. This layout forms a uniformly distributed rigid constraint through multi-point synchronous locking, suppressing the multi-dimensional deformation and vibration that may occur during the worktable 3 during processing, ensuring a uniform distribution of positioning force, thereby greatly improving the overall rigidity and positioning stability of the large worktable 3 during heavy-duty milling. When the worktable 3 is flipped, the fallen debris falls into the material collection box 6 that is slidably connected below under the action of gravity. After cleaning, the operator can easily pull out the material collection box 6 full of debris along the slide rail for centralized processing. The material collection box 6 is designed to achieve automatic collection and rapid removal of debris through a sliding dust collection method, effectively preventing debris from scattering and contaminating the machine tool and working environment, greatly improving cleaning efficiency and maintaining the cleanliness of the work site.

[0021] Please see Figure 1 The frame 1 is slidably connected to a collection box 6, which is located below the workbench 3. When the workbench 3 is flipped, the falling debris falls into the collection box 6 directly below under the action of gravity. After cleaning, the operator can easily pull out the collection box 6 full of debris along the slide rail for centralized processing. The design of the collection box 6 realizes the automatic collection and rapid removal of debris through the sliding dust collection method, which improves the cleaning efficiency and keeps the work site clean.

[0022] Example 2: Please see Figures 1-2 The milling device 2 includes a translation frame 21, a lifting seat 22, a mounting plate 23, and a CNC milling cutter 24. The translation frame 21 is fixedly connected to the machine frame 1, the lifting seat 22 is slidably connected to the translation frame 21, the mounting plate 23 is slidably connected to the lifting seat 22, and the CNC milling cutter 24 is fixedly connected to the mounting plate 23. In use, the translation frame 21 is fixedly connected to the machine frame 1 to provide a transverse foundation, the lifting seat 22 slides vertically along the translation frame 21 to adjust the height of the milling cutter, and the mounting plate 23 drives the CNC milling cutter 24 to perform horizontal feed through the lifting seat 22. This three-axis linkage structure realizes the precise trajectory movement of the milling cutter in three-dimensional space through rigid sliding combination, which can not only complete the precision machining of complex curved surface parts, but also effectively disperse cutting vibration through the integral machine frame 1 structure, ensuring the stability and machining accuracy of the milling process.

[0023] Please see Figures 1-2Both the translation frame 21 and the lifting seat 22 include a base 25, an adjusting motor 26, a lead screw 27, and a threaded sleeve 28. The adjusting motor 26 is fixedly connected to the base 25, the lead screw 27 is rotatably connected to the base 25, the threaded sleeve 28 is threadedly connected to the lead screw 27, the output end of the adjusting motor 26 is fixedly connected to the lead screw 27, the lifting seat 22 is fixedly connected to the threaded sleeve 28 on the translation frame 21, and the mounting plate 23 is fixedly connected to the threaded sleeve 28 on the lifting seat 22. In use, the adjusting motor 26 is fixed to the base 25 and drives the lead screw 27. The rotation of rod 27 drives the threaded sleeve 28, which is threaded to it, to produce precise linear displacement. The lifting seat 22 moves laterally via the threaded sleeve 28 of the translation frame 21, while the mounting plate 23 is vertically fed via the threaded sleeve 28 of the lifting seat 22. The milling device 2 can achieve precise positioning of the milling cutter in both horizontal and vertical directions and has a transmission self-locking function, effectively resisting cutting reaction forces during machining, ensuring the accuracy and stability of the milling trajectory, and providing reliable motion control for precision machining.
