Description

Technical Field

[0001] The utility model relates to the technical field of numerical control milling machines, and specifically relates to a numerical control milling machine which is convenient for disassembling and assembling processing parts. Background Art

[0002] Existing CNC milling machines often present numerous inconveniences when it comes to disassembling and adjusting parts. Traditional CNC milling machines often require complex mechanical structures or tools to disassemble and assemble parts, which not only increases operational difficulty but also reduces efficiency. Furthermore, traditional CNC milling machines also have limitations in their ability to secure and adjust parts during machining, impacting both precision and safety.

[0003] To address these issues, several existing solutions have emerged, such as electric slides and pneumatic clamps. However, these solutions still have limitations and shortcomings in practical applications. For example, while electric slides can achieve automated control, they are expensive and complex to maintain. While pneumatic clamps can quickly clamp parts, their grip strength and stability still need to be improved. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a CNC milling machine for convenient disassembly and assembly of processing parts, comprising a milling machine base, the milling machine base is provided with a support plate, and the support plate is provided with a slide rail, a pad and a bracket in sequence from front to back; a hollow slider is provided on the slide rail for sliding, the hollow slider is provided with a connecting plate, a threaded locking rod is inserted into the connecting plate, and the lower end of the threaded locking rod extends to the lower side of the connecting plate; a hydraulic cylinder is provided on the bracket, the telescopic end of the hydraulic cylinder is adjacent to the pad, the telescopic end of the hydraulic cylinder is provided with a propulsion push rod, and an abutment plate corresponding to the propulsion push rod is provided on the connecting plate; the abutment surface of the abutment plate is provided with a first clamping groove, a second clamping groove, a third clamping groove and a fourth clamping groove in a horizontal direction, and the notches of the first clamping groove, the second clamping groove, the third clamping groove and the fourth clamping groove are enlarged at a time.

[0006] Preferably, a friction surface is provided on the slide rail, and the threaded locking rod abuts against the friction surface when rotating and locking.

[0007] Preferably, the number of the hollow sliding blocks is 2, which are respectively arranged on the left and right sides of the lower end surface of the connecting plate.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3 This utility model provides a technical solution: a CNC milling machine designed specifically for convenient assembly and disassembly of machined parts. The milling machine boasts a compact yet powerful structure, primarily comprising a milling machine base 1, atop which is mounted a support plate 2. The surface of the support plate 2 is arranged, from front to back, with slide rails 3, a pad 4, and a bracket 5. The rational layout of these components ensures the stability and accuracy of the milling machine.

[0020] A hollow slider 6 is slidably mounted on the slide rail 3, with a connecting plate 7 fixed above it. A threaded locking rod 8 is inserted into the connecting plate 7, with its lower end extending below the connecting plate 7 to facilitate precise locking and adjustment. A hydraulic cylinder 9 is mounted above the bracket 5, with its telescopic end adjacent to the pad 4, ensuring flexible operation of the milling machine. A propulsion rod 10 is attached to the telescopic end of the hydraulic cylinder 9, while a corresponding abutment plate 11 is mounted on the connecting plate 7.

[0021] The abutment surface of the abutment plate 11 is provided with four horizontally arranged grooves: a first groove 12, a second groove 13, a third groove 14, and a fourth groove 15. The slots of these four grooves increase in size to accommodate parts of varying sizes, thereby enhancing the versatility and flexibility of the milling machine. A friction surface 16 is also designed on the surface of the slide rail 3. When the threaded locking rod 8 is rotated and locked, it contacts the friction surface 16, ensuring the stability of the connecting plate 7 and thus guaranteeing machining accuracy.

[0022] To further enhance the stability and load-bearing capacity of the milling machine, two hollow slides 6 are designed, mounted on the left and right sides of the lower end surface of the connecting plate 7. Furthermore, three brackets 5 are evenly distributed laterally to ensure structural stability and uniform load distribution throughout the milling machine, thereby enhancing its reliability and durability.

[0023] To facilitate operator adjustment and maintenance, an L-shaped pull rod 17 is designed on the outer wall of the connecting plate 7. The longitudinal rod of the L-shaped pull rod 17 extends upward, allowing the operator to pull and adjust it, thereby achieving precise control of the connecting plate 7. Through these carefully designed structures and components, the CNC milling machine not only improves machining efficiency but also greatly simplifies the assembly and disassembly process, making operation more convenient and improving production efficiency.

[0024] Working principle: When the present invention is working, the CNC milling machine allows the connecting plate 7 to slide freely in the horizontal direction through the combination of the slide rail 3 and the hollow slider 6, thereby adjusting the position of the processed parts.

[0025] When the parts are placed on the pad 4, the threaded locking rod 8 is rotated so that its lower end is in close contact with the friction surface 16 on the slide rail 3, thereby achieving stable fixation of the connecting plate 7 and the parts thereon.

[0026] The hydraulic cylinder 9 on the bracket 5 is started, and its telescopic end pushes the propulsion rod 10 to move forward until it contacts the abutment plate 11 on the connecting plate 7.

[0027] The abutting plate 11 is provided with first to fourth clamping grooves 12 to 15 of different sizes. According to the shape and size of the part, a suitable clamping groove is selected for clamping.

[0028] Precise control of the hydraulic cylinder 9 enables the push rod 10 to apply appropriate pressure to ensure that the part does not move or loosen during the processing.

[0029] After the parts are firmly clamped, the CNC milling machine starts the processing operation. Since the position of the connecting plate 7 and the parts can be flexibly adjusted, the parts processing requirements of different shapes and sizes can be adapted.

[0030] During the processing, the CNC system will control the movement trajectory and speed of the milling cutter according to the preset program to ensure processing accuracy and efficiency.

[0031] When different parts need to be processed, it is only necessary to loosen the fixation of the connecting plate 7 by rotating the threaded locking rod 8, and then slide the hollow slider 6 to adjust the position or remove the connecting plate 7 for replacement.

[0032] The telescopic end of the hydraulic cylinder 9 can be retracted to separate the propulsion rod 10 from the abutment plate 11, making it easier to disassemble and replace parts.

[0033] The L-shaped pull rod 17 on the outer side wall of the connecting plate 7 provides additional operational convenience. By pulling the longitudinal rod portion of the L-shaped pull rod 17, the position of the connecting plate 7 can be assisted to be adjusted or other auxiliary operations can be performed.

[0034] In summary, the CNC milling machine achieves rapid positioning, stable clamping and flexible processing of parts through the coordinated work of components such as slide rails, hollow sliders, and hydraulic cylinders. It also facilitates the disassembly and replacement of parts, thereby improving processing efficiency and flexibility.
