Description

Technical Field

[0001] This utility model relates to a gantry machining device, specifically a gantry machining device with a built-in chip removal structure, belonging to the field of gantry machining technology. Background Technology

[0002] CNC gantry milling machines are commonly used machine tools in modern industry, possessing strong processing capabilities and high processing efficiency.

[0017] This utility model provides a gantry machining device with a built-in chip removal structure.

[0018] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The system includes a machine tool body 1, a protective housing 100 mounted on top of the machine tool body 1, a door mounted on the front of the protective housing 100, a processing equipment mechanism 3 mounted on top of the machine tool body 1, a movable processing table mechanism 2 mounted inside the machine tool body 1, chip removal grooves 4 on both sides of the machine tool body 1, and two connecting grooves 200 symmetrically distributed with respect to the vertical center line of the machine tool body 1 at the bottom of the machine tool body 1. The two ends of the connecting grooves 200 are respectively connected to the two chip removal grooves 4, and the connecting grooves 200 are V-shaped. Screw shafts 5 are installed inside the chip removal grooves 4, and one end of each screw shaft 5 passes through one side of the inside of the two chip removal grooves 4 and is rotatably connected to the machine tool body 1. The other side of the inside of each chip removal groove 4 is formed with... Two auger shafts 5 have two circular holes, and their other ends pass through the two circular holes and extend to the outside of the machine tool body 1. A transmission structure is provided between the two auger shafts 5. Multiple convex grooves 555 are opened on the outside of the auger shafts 5. A convex insert plate 501 is slidably arranged inside the convex grooves 555. A auger blade 500 is fixedly connected between the multiple convex insert plates 501. The auger blade 500 is arranged inside the chip removal groove 4. An annular rotating seat 10 is sleeved on the outside of the other end of the auger shaft 5. Multiple convex abutment plates 11 are installed on the inside of the annular rotating seat 10. The convex abutment plates 11 are slidably arranged inside the convex grooves 555 and in contact with the convex insert plates 501. An annular frame 12 is rotatably connected to the outside of the annular rotating seat 10. A connection structure is provided between the annular frame 12 and the machine tool body 1.

[0019] The connecting structure includes a cylinder 9, which is sleeved on the outer side of the other end of the auger shaft 5. The cylinder 9 is fixedly connected to the machine tool body 1 and communicates with a circular hole. Multiple positioning grooves 900 are provided on one side of the cylinder 9, and positioning rods 13 are provided inside each of the multiple positioning grooves 900. The multiple positioning rods 13 are fixedly connected to the ring frame 12. Slots 14 are provided on the outer side of each of the multiple positioning rods 13. A rotating plate 15 is rotatably connected to the outer side of the cylinder 9. Multiple arc-shaped grooves 16 are provided on one side of the rotating plate 15. Circular blocks 17 are slidably arranged inside each of the multiple arc-shaped grooves 16. Insert blocks 18 are installed at one end of each of the multiple circular blocks 17. The insert blocks 18 pass through the outer side of the cylinder 9 and extend into the slot 14. The insert blocks 18 are slidably connected to the cylinder 9. The structure also includes a sliding groove 19 and a rectangular tube 21. The sliding groove 19 is opened on the other side of the rotating plate 15. Two circular grooves 20 are formed inside the sliding groove 19. The rectangular tube 21 is set on the other side of the rotating plate 15. One end of the rectangular tube 21 is fixedly connected to the machine tool body 1. A rectangular block 22 is slidably arranged inside the rectangular tube 21. A cylindrical block 23 is fixedly connected to one end of the rectangular block 22. The cylindrical block 23 is set inside one of the circular grooves 20. A spring 24 is provided inside the rectangular tube 21. The two ends of the spring 24 are fixedly connected to the rectangular block 22 and the rectangular tube 21, respectively. A limit groove 210 is opened on the front side of the rectangular tube 21. A push rod 25 is slidably arranged inside the limit groove 210. One end of the push rod 25 is fixedly connected to the rectangular block 22.

[0020] Specifically, pushing the push rod 25 causes it to slide inside the limiting groove 210, while the spring 24 is elastically compressed. When the push rod 25 slides to one side of the limiting groove 210, the rectangular block 22 drives the cylindrical block 23 to move into the sliding groove 19. The cylindrical block 23 then moves out from one of the circular grooves 20. Next, rotating the rotating plate 15 causes multiple circular blocks 17 to slide inside multiple arc-shaped grooves 16, and these blocks drive multiple insert blocks 18 to move out from multiple slots 14. When the rotating plate 15 rotates to a certain position, the spring 24 elastically returns to its original position, and the cylindrical block 23 is then engaged in the sliding groove. In another circular groove 20 within the moving groove 19, the rotating plate 15 is limited. Then, the operator pulls the positioning rod 13, which, through the annular frame 12, drives multiple convex abutment plates 11 to be pulled out from multiple convex grooves 555. This allows for the disassembly of components such as the annular rotating seat 10 and the annular frame 12. Further pulling the auger blade 500 outward causes multiple convex insert plates 501 to be moved out from multiple convex grooves 555, thus completing the disassembly of the auger blade 500. Through this structural design, the auger blade 500 can be replaced individually, facilitating timely replacement of worn blades and reducing maintenance costs.

[0021] The ring-shaped rotating seat 10, the ring-shaped frame 12, and the positioning rod 13 provide support for the auger shaft 5, ensuring its stability during operation.

[0022] The mobile processing table mechanism 2 and the processing equipment mechanism 3 are existing technical structures and will not be described in detail in this embodiment.

[0023] Example 2, please refer to Figure 1 , Figure 2 and Figure 3 The transmission structure includes a protective frame 7, which is fixedly connected to one side of the machine tool body 1. The protective frame 7 has two sprockets 6 inside, which are fixedly connected to the outer side of one end of two auger shafts 5 respectively. The two sprockets 6 are connected to each other by chain drive. A motor 8 is fixedly connected to one side of the protective frame 7. The output end of the motor 8 passes through one side of the protective frame 7 and is rotatably connected to the protective frame 7. The output end of the motor 8 is fixedly connected to one of the auger shafts 5. A disassembly plate 700 is fixedly connected to the top of the protective frame 7 by bolts.

[0024] Specifically, after the personnel clean the chips into the two chip discharge slots 4 and the two connecting slots 200, they start the motor 8. The model of the motor 8 is not specifically limited, but is based on the equipment. The output end of the motor 8 drives the sprocket 6 on one of the auger shafts 5 to rotate. The two sprockets 6 are driven by the chain, so the two auger shafts 5 can drive the two auger blades 500 to rotate, which can discharge the chips inside the device. The top of the protective frame 7 is fixedly connected to a disassembly plate 700 by bolts. The disassembly plate 700 can be disassembled to facilitate personnel to maintain the sprocket 6 and apply lubricating oil, ensuring the normal operation of the transmission structure and extending the service life of the equipment.
