Technical Field

[0001] This utility model relates to the field of CNC technology, specifically to a CNC machining platform with a flipping function. Background Technology

[0002] In CNC machining, three-axis CNC machine tools are typically used for simple planar machining. However, with the development of industrial technology, the demand for machining complex curved surfaces is increasing, and traditional three-axis CNC machine tools can no longer meet the requirements of high-precision and high-efficiency machining. Therefore, CNC machining platforms have emerged. By adding rotary axes to three-axis machine tools, they enable the machine tools to perform more complex machining actions, thereby improving machining flexibility and accuracy. The advent of CNC machining platforms not only enables the machining of complex curved surfaces that are difficult for traditional three-axis machine tools to complete, but also improves machining efficiency, shortens production cycles, and reduces production costs. Furthermore, CNC machining platforms have broad application prospects in industries such as aerospace, automotive manufacturing, and mold manufacturing, providing strong technical support for these industries with high precision requirements.

[0003] While existing CNC machining platforms can perform complex machining of parts, some parts are fixed in place by fixtures, preventing further machining. This necessitates interrupting the machine operation, manually disassembling, flipping, and re-fixing the parts to complete the overall machining process. This process is not only time-consuming but also increases operational complexity and reduces machining efficiency. Therefore, this invention proposes a CNC machining platform with a flipping function. Summary of the Invention

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] In this embodiment, refer to Figures 1-8The present invention relates to a CNC machining platform with a flipping function, comprising a base 1, on which a fixed axis 2 and a moving axis 3 are mounted. The fixed axis 2 is fixedly mounted on the base 1. The base 1 is provided with a sliding component 1A and a drive component 1B that slide with the moving axis 3. The drive component 1B can be driven by a lead screw nut or a linear motor to achieve precise control of the moving axis 3. Both the fixed axis 2 and the moving axis 3 include a flipping mechanism and a bridge plate 4. A clamp 5 is provided on one side of the bridge plate 4. The clamp 5 can be an automatic clamp 5, such as an electrically controlled or hydraulic clamp 5, so that when the fixed axis 2 and the moving axis 3 are engaged, the workpiece can be positioned and clamped quickly and accurately, thereby completing the automated flipping operation. The flipping mechanism includes a base plate 6 and a first rotating component 7 and a first angle limiting component 8 located on both sides of the base plate 6. The sliding component 1A and the drive component 1B are both connected to the base plate 6 of the moving axis 3, so that the moving axis 3 slides back and forth on the base 1. The two ends of the bridge plate 4 are connected to the first rotating component 7 and the first angle limiting component 8, respectively, so that the first rotating component 7 drives the bridge plate 4 to rotate. Through the cooperation of the first rotating component 7 and the first angle limiting component 8, the bridge plate 4 can be flipped to different angles and positioned, thereby completing the precise flipping and positioning of the workpiece.

[0029] Furthermore, the bridge plate 4 is equipped with a second rotating component 9 and a second angle limiting component 10 that cooperate with the clamp 5. Through the cooperation of the second rotating component 9 and the second angle limiting component 10, the workpiece can achieve more complex angle adjustments, thereby adapting to different processing requirements. When the fixed shaft 2 and the moving shaft 3 are docked, the clamping surface of the workpiece can be adjusted by the cooperation of the second rotating component 9 and the second angle limiting component 10, thereby avoiding damage to critical parts of the workpiece. Users can install the second rotating component 9 and the second angle limiting component 10 on the moving shaft 3 and the fixed shaft 2 according to processing requirements. In this embodiment, the second rotating component 9 and the second angle limiting component 10 are only installed on the bridge plate 4 of the fixed shaft 2. Furthermore, both the first rotating component 7 and the second rotating component 9 are swing cylinders.

[0030] The first angle limiting assembly 8 includes a first driving member 8A and a rotating disk 8B for synchronization with the bridge plate 4. The first driving member 8A is located on one side of the rotating disk 8B. The outer side of the rotating disk 8B is surrounded by a plurality of limiting teeth 81B. The output end of the first driving member 8A is provided with a limiting tooth cone 81A that cooperates with the limiting teeth 81B. One end of the base plate 6 is equipped with an air inlet seat 15 for connecting to an external air source. A detachable limiting block 82B is provided on one side of the rotating disk 8B. When the bridge plate 4 needs to be fixed during handling or placement in a warehouse, the limiting block 82B can be used to lock the rotating disk 8B, thereby preventing unnecessary rotation of the bridge plate 4 due to vibration or accidental collision during transportation.

[0031] In this embodiment, the angle between two adjacent limiting teeth 81B is 10 degrees, allowing the adjustment angle of the rotating disk 8B to be 10 degrees or an integer multiple thereof. This method ensures that various angle requirements can be met, thus providing users with a highly customized solution. In actual use, users can select and replace rotating disks 8B with different adjustment angles according to their specific needs. This design makes the adjustment of the rotation angle more flexible and diverse, allowing users to easily adjust the bridge plate 4 to the optimal working angle according to different application scenarios and purposes.

[0032] In addition, support seats 6A are provided on both sides of the base plate 6, and rotatable rotating seats 6B are provided on the support seats 6A. A placement seat 6C for connecting to the bridge plate 4 is provided on one side of the rotating seat 6B. The rotating disk 8B and the first rotating component 7 are both connected to the bridge plate 4 through the rotating seat 6B. The rotating seat 6B is rotatably mounted on the support seat 6A through bearings and connected to the bridge plate 4 through the placement seat 6C. The rotating seat 6B is connected to the first rotating component 7 and the rotating disk 8B through connector 6D and adjusting disk 6E, respectively. The bearings enable the rotating seat 6B to rotate flexibly, ensuring the stability and accuracy of the bridge plate 4 at different angles.

[0033] A third angle limiting component 11 for cooperating with the rotating seat 6B is installed on the outer side of the first rotating component 7. Both the second angle limiting component 10 and the third angle limiting component 11 include a stop plate 12 and a third driving component 13. The output end of the third driving component 13 is provided with a pin 14 that cooperates with the stop plate.

[0034] In this embodiment, four third driving elements 13 are provided, which are distributed in four directions on the outer circumference of the swing cylinder. The four third driving elements 13 are sequentially divided into a first driving element 13A, a second driving element 13B, a third driving element 13C, and a fourth driving element 13D. The gear shift plate 12 is installed on the side of the rotary seat 6B near the swing cylinder.

[0035] like Figure 8As shown, the gear shift plate 12 is provided with a gear shift groove, which has an inner groove 12A and an outer groove 12B. Both the inner groove 12A and the outer groove 12B have an included angle of 90 degrees. The first drive element 13A engages with the inner groove 12A via a pin 14, and the second drive element 13B and the third drive element 13C engage with the outer groove 12B via pins 14, allowing for fixed angle restrictions of 90 degrees, 180 degrees, and 270 degrees. When a 90-degree rotation is required, the gear shift groove is restricted by the pins 14 on the first drive element 13A and the second drive element 13B. Simultaneously, the pins 14 on the third drive element 13C and the fourth drive element 13D are retracted to avoid affecting the rotation of the bridge plate 4. When a 180-degree or 270-degree angle rotation is required, the pins 14 on the first, second, and fourth drive elements 13D are retracted, and the gear shift groove is restricted by the pin 14 on the third drive element 13C. Furthermore, when rotating 180 degrees, adjustment must be completed by rotating in the opposite direction.

[0036] The gear shift plate 12 is also provided with three tapered holes 12C that cooperate with the fourth drive element 13D. The tapered holes 12C are arranged around the gear shift plate, and the tapered holes 12C form an included angle of 120 degrees. In use, the pin 14 on its output end can be pushed by the fourth drive element 13D to cooperate with the tapered holes 12C to lock the tilt angle of the bridge plate 4.

[0037] The arrangement of the first drive element 13A, the second drive element 13B, the third drive element 13C, and the fourth drive element 13D allows the user to quickly adjust the bridge plate 4 to the commonly used tilt angle during operation, thereby improving work efficiency. When using the third drive element 13, the fixing block on the second drive element must be retracted to avoid affecting the rotation of the bridge plate 4. Similarly, when using the second drive element, all the pins 14 on the third drive element 13 must be retracted. Furthermore, the included angle between the inner groove 12A and the outer groove 12B can be 30 degrees or 45 degrees. In actual use, different angled stop plates 12 can be replaced according to different requirements to adapt to different rotation angle needs.

[0038] Furthermore, the sliding component 1A is either a linear guide module or a rigid guide module. By sliding the linear guide module or the rigid guide module, the moving shaft 3 slides smoothly on the base 1, thereby achieving docking with the fixed shaft 2. The linear guide module is suitable for high-speed, high-precision machining applications, while the rigid guide module is suitable for heavy cutting and the machining of large molds. In this embodiment, a linear guide module is installed on the base 1, thereby enabling the moving shaft 3 to maintain high positioning accuracy and repeatability.

[0039] The beneficial effects of this utility model are as follows: Through the cooperation of the first rotating component 7 and the first angle limiting component 8, both the moving shaft 3 and the clamp 5 on the fixed shaft 2 can be flipped, thereby driving the workpiece to perform multi-angle processing. Furthermore, through the cooperation of the sliding component 1A and the driving component 1B, the moving shaft 3 and the clamp 5 on the fixed shaft 2 cooperate with each other to achieve workpiece docking and flipping, thereby improving processing efficiency while ensuring processing accuracy.
