Description

Technical Field

[0001] This utility model relates to the field of machining center technology, and in particular to a CNC gantry machining center. Background Technology

[0002] CNC gantry machining centers are advanced CNC machine tools widely used in machinery manufacturing, automobile manufacturing, aerospace and other fields. They rely on cutting tools to remove material from workpieces, achieving the required precision in workpiece geometry, contours, and dimensions. They can perform various machining processes, such as drilling, milling, boring, tapping, and grinding. With their high precision, high efficiency, high reliability, wide applicability, and user-friendly human-machine interface, CNC gantry machining centers play a vital role in modern industrial manufacturing.

[0003] When a CNC gantry machining center mills a workpiece using a cutting tool, it generates a significant amount of debris. Due to friction between the tool and the workpiece, the temperature of these debris can range from 100°C to 120°C. The high-speed rotation of the cutting tool and the movement of the workpiece cause the debris to splash at high speeds. If these hot debris come into contact with the exposed lead screw during this splashing process, they can easily adhere due to the large temperature difference. If not handled promptly, the debris will harden on the lead screw after cooling, which will damage the thread accuracy of the lead screw, causing deviations in the fit between the lead screw and the connecting parts. This will affect the accuracy and stability of the entire transmission system. This decrease in accuracy will directly affect the quality of the machined workpiece, making it unable to meet design requirements and potentially leading to serious equipment failures. Therefore, this application provides a CNC gantry machining center to meet this need. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a CNC gantry machining center to solve the problem of iron filings adhering to the lead screw, causing deviations in the fit between the lead screw and the connecting parts, which in turn affects the accuracy and stability of the entire transmission system.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a CNC gantry machining center, including a machining platform and a chip removal machining table disposed in the machining platform.

[0031] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a CNC gantry machining center, including a machining platform 1 and a chip removal machining table 4 disposed in the machining platform 1. A first lead screw 9 is rotatably disposed in the machining platform 1 to drive the chip removal machining table 4 to move, and cleaning plates 2 for cleaning the first lead screw 9 are embedded in both ends of the machining platform 1. A drive mechanism for driving the two cleaning plates 2 to move towards each other is installed in the machining platform 1. A through hole 17 is opened at the center of the cleaning plate 2, and a cleaning brush 15 tightly connected to the lead screw is fixed in a ring array on the inner wall of the through hole 17.

[0032] A milling cutter processing device 3 is installed above the processing platform 1, and a drive motor 6 connected to the first lead screw 9 is fixed to the outer wall of the processing platform 1. A first connecting seat 20 is fixed at the center of the bottom end face of the chip removal processing table 4, and a second connecting seat 21 is fixed at both ends of the bottom of the chip removal processing table 4. Supporting slide rods 5 are fixed on both sides of the inner wall of the processing platform 1 and are slidably inserted into the second connecting seat 21. The first lead screw 9 is threaded into the first connecting seat 20. After the drive motor 6 is started, it drives the first lead screw 9 to rotate. During the rotation of the first lead screw 9, it drives the first connecting seat 20 and the chip removal processing table 4 to reciprocate in the processing platform 1. During the movement of the chip removal processing table 4, the second connecting seat 21 moves on the supporting slide rod 5. Since the chip removal processing table 4 will block the iron chips, the first lead screw 9 located below the chip removal processing table 4 will not be affected by the iron chips. Therefore, even if the chip removal processing table 4 is not at the center of the processing platform 1, the two cleaning plates 2 can still meet the cleaning needs of both ends of the first lead screw 9 without moving to the center position.

[0033] like Figures 3 to 5 As shown, the driving mechanism includes a second lead screw 14 symmetrically installed in the processing platform 1 and a cleaning motor 7 fixed to the side wall of the processing platform 1. The shaft of the cleaning motor 7 is fixed to the second lead screw 14. A protective cover 8 is fixed in the middle of the processing platform 1 and sleeved on the second lead screw 14. The bottom end of the protective cover 8 has a groove 19. Cleaning rings 18 are fixedly installed at both ends of the cleaning plate 2. The cleaning rings 18 fit snugly onto the support slide rod 5. Connecting plates 13 are fixed on both sides of the bottom end face of the cleaning plate 2. A moving block 11 is sleeved on the second lead screw 14. A screw hole 16 is opened at the center of the moving block 11, and the bottom end of the moving block 11 passes through the protective cover 8 and is fixed to the connecting plate 13. The second lead screw 14 is threaded. The two ends in opposite directions are threaded into the screw holes 16 on the two moving blocks 11 respectively. The two second lead screws 14 are fixedly sleeved with synchronous pulleys 12 at one end of the processing platform 1. The synchronous pulleys 12 are meshed and sleeved with a synchronous belt 10. When the cleaning motor 7 is started, it drives the second lead screws 14 to rotate. The second lead screws 14 cause the two cleaning plates 2 to move towards each other. During the movement of the cleaning plates 2, the cleaning brush 15 cleans the iron filings on the surface of the first lead screw 9, avoiding the iron filings adhering to the first lead screw 9 and affecting the accuracy and stability of the entire transmission system. The moving block 11 in the second lead screw 14 passes through the bottom of the protective cover 8 and is fixed to the connecting plate 13 on the cleaning plate 2. The protective cover 8 protects the surface of the second lead screw 14.

[0034] The working principle of the technical solution provided by this utility model is as follows:

[0035] In use, after the drive motor 6 starts, it drives the first lead screw 9 to rotate. During the rotation of the first lead screw 9, it drives the first connecting seat 20 and the chip removal processing table 4 to reciprocate in the processing platform 1. During the movement of the chip removal processing table 4, the second connecting seat 21 moves on the support slide rod 5. When cleaning the first lead screw 9, the cleaning motor 7 is started to drive the second lead screw 14 to rotate. The two second lead screws 14 rotate simultaneously through the synchronous pulley 12 and the synchronous belt 10. The second lead screw 14 causes the two cleaning plates 2 to move towards each other. During the movement of the cleaning plates 2, the cleaning brush 15 cleans the iron filings on the surface of the first lead screw 9. The cleaning rings 18 at both ends of the cleaning plates 2 clean the iron filings on the surface of the support slide rod 5, avoiding the iron filings adhering to the first lead screw 9 and affecting the accuracy and stability of the entire transmission system. The moving block 11 in the second lead screw 14 passes through the bottom of the protective cover 8 and is fixed to the connecting plate 13 on the cleaning plate 2. The protective cover 8 protects the surface of the second lead screw 14 and avoids the iron filings from affecting the second lead screw 14.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
