Description

Technical Field

[0001] This utility model relates to the technical field of loading devices for CNC machine tools, and more specifically, it relates to a loading device for CNC machine tools. Background Technology

[0002] CNC machine tools analyze pre-programmed control codes or symbolic instructions, converting them into digital signals, which are then transmitted to the CNC system via an information carrier. After processing, the system sends various control commands to the machine tool, driving it to automatically complete precision machining according to the design drawings, accurately realizing the shape and dimensions of the parts.

[0003] However, existing CNC machine tools still have the following problems when in use: 1. Currently, CNC machine tools typically rely on manual labor to feed bar stock into the feed hole. This repetitive operation, which involves long periods of time and high frequency, easily leads to worker fatigue, resulting in high labor intensity and impacting overall production efficiency and work stability.

[0004] 2. Existing CNC machine tool loading devices often lack the ability to adapt to bar stock of different lengths. Due to structural or control limitations, they are difficult to adjust flexibly to meet the processing needs of materials of various specifications, thus limiting the diversity and compatibility of production.

[0005] 3. Existing machine tool feeding mechanisms often fail to consistently feed only one bar at a time when pushing bar stock. This unstable feeding method easily leads to jamming, leakage, or processing interruption, affecting the reliability of continuous production and processing quality.

[0006] In view of this, we propose a feeding device for CNC machine tools. Utility Model Content

[0007] In view of the problems existing in the prior art, this utility model provides a feeding device for CNC machine tools to solve the technical problems mentioned in the background art. Technical solution

[0009] The present invention is further configured such that the central axis of the guide shell coincides with the circumferential center of the feed inlet of the CNC machine tool.

[0010] The present invention is further configured such that the inner wall of the extended shell is flush with the inner wall of the supporting shell.

[0011] The present invention is further configured such that the pushing structure includes a bracket, the bracket is fixedly connected to an electric push rod two, and the telescopic end of the electric push rod two is fixedly connected to a push plate.

[0012] The present invention is further configured such that the extended shell is fixedly connected to and communicates with a fixing ring, the push plate is located inside the fixing ring, and the push plate and the fixing ring are slidably engaged.

[0013] The present invention is further configured such that the feeding structure includes two limiting plates, which are slidably connected to the upper sides of the support shell and the extension shell, respectively, and a telescopic rod is fixedly connected between the two limiting plates.

[0014] The present invention is further configured such that the lower sides of the extended shell and the supporting shell are slidably connected to the limiting plate two, and the two limiting plates two are fixedly connected to the telescopic rod two.

[0015] The present invention is further configured such that a gap is provided between the first limiting plate and the adjacent second limiting plate, a connecting frame is fixedly connected between the first limiting plate and the adjacent second limiting plate, and an electric push rod three is fixedly connected to both the extension shell and the support shell, with the telescopic end of the electric push rod three being fixedly connected to the connecting frame. Beneficial effects

[0016] Compared with the prior art, this utility model provides a feeding device for CNC machine tools, which has the following beneficial effects: This invention uses an electric push rod to drive the extension shell to slide, allowing for flexible adjustment of the overall length of the material-containing cavity formed by the support shell and the extension shell. This design enables the feeding device to adapt to and accommodate rod-shaped materials of different lengths, improving the versatility of the equipment and solving the limitation of traditional feeding devices that can only be used for materials of specific lengths due to their fixed dimensions.

[0017] This invention employs a precision feeding structure consisting of a first limiting plate and a second limiting plate. These two plates are linked by an electric push rod to achieve an alternating action of "releasing one piece and blocking the next." This mechanical interlocking mechanism ensures that only one rod-shaped material can enter the guide shell sequentially, avoiding the risk of multiple materials rolling down or jamming simultaneously, thus guaranteeing the continuity and reliability of feeding the CNC machine tool.

[0018] The entire feeding process of this invention, including cavity length adjustment, material release one piece at a time, and final push into the machine tool, is automatically completed by electric push rods and other electronically controlled components. This achieves precise docking and collaborative operation with CNC machine tools, greatly reducing manual intervention and improving the automation level and overall work efficiency of the production line.

[0024] Please see Figures 1-5A feeding device for a CNC machine tool includes a lifting platform 2 located on the feeding side of the CNC machine tool 1. Four columns 3 are fixedly connected to the lifting platform 2, and a support shell 4 is fixedly connected to the four columns 3. A guide shell 5 is fixedly connected to and communicates with the support shell 4. An extension shell 6 is slidably connected between the guide shell 5 and the support shell 4. A fixing plate 7 is fixedly connected to the upper side of the support shell 4, and a fixing column 8 is slidably connected to the fixing plate 7. A fixing plate 9 is fixedly connected to the upper side of the extension shell 6, and the fixing column 8 is fixed to the fixing plate 9. An electric push rod 10 is fixedly connected to the guide shell 5, and the telescopic end of the electric push rod 10 is fixedly connected to the extension shell 6. The extension shell 6 is provided with a pushing structure, and a discharging structure is provided between the extension shell 6 and the support shell 4. The central axis of the guide shell 5 coincides with the center circumferential direction of the feed inlet of the CNC machine tool 1. The inner wall of the extension shell 6 is flush with the inner wall of the support shell 4.

[0025] Please see Figure 2 and Figure 4 The material pushing structure includes a bracket 11, an electric push rod 12 fixedly connected to the bracket 11, and a push plate 13 fixedly connected to the telescopic end of the electric push rod 12; the extension shell 6 is fixedly connected to and connected to a fixing ring 14, the push plate 13 is located inside the fixing ring 14, and the push plate 13 and the fixing ring 14 are in sliding fit.

[0026] Please see Figure 2 , Figure 4 and Figure 5 The feeding structure includes two limiting plates 15, which are slidably connected to the upper sides of the support shell 4 and the extension shell 6, respectively. A telescopic rod 16 is fixed between the two limiting plates 15. Limiting plates 17 are slidably connected to the lower sides of the extension shell 6 and the support shell 4, and a telescopic rod 18 is fixed between the two limiting plates 17. A gap is provided between the limiting plates 15 and the adjacent limiting plates 17. A connecting frame 19 is fixed between the limiting plates 15 and the adjacent limiting plates 17. Electric push rods 20 are fixed to both the extension shell 6 and the support shell 4. The telescopic end of the electric push rod 20 is fixed to the connecting frame 19.

[0027] The working principle of this utility model: Control the lifting platform 2, adjust the height of the support shell 4 and guide shell 5 to align the guide shell 5 with the feed inlet of the CNC machine tool 1, and activate the electric push rod 10. The telescopic end of the electric push rod 10 drives the extension shell 6 to slide along the support shell 4 and guide shell 5. Adjust the width between the extension shell 6 and the support shell 4 according to the length of the rod-shaped material to accommodate rod-shaped materials of different lengths. During the above process, the fixing plate 2 9 drives the fixing column 8 to slide along the fixing plate 1 7, and the distance between the two limiting plates 1 15 and the two limiting plates 2 17 increases. The telescopic ends of the telescopic rod 1 16 and the telescopic rod 2 18 extend, further increasing the stability between the extension shell 6 and the support shell 4. Then, place the rod-shaped material into the cavity formed by the support shell 4 and the extension shell 6, and the rod-shaped material is neatly arranged between the extension shell 6 and the support shell 4.

[0028] Initially, the two limiting plates 15 block the bottommost rod-shaped material. When the CNC machine tool 1 loads the material, it controls the two drive rods 3. The telescopic ends of the electric drive rods 3 and 20 drive the connecting frame 19 to move upward. The connecting frame 19 drives the limiting plates 15 and 2 to move upward. The limiting plates 15 release the obstruction of the first rod-shaped material, and the limiting plate 2 17 is inserted between the first and second rod-shaped materials. When the two limiting plates 15 release the obstruction of the first rod-shaped material, the first rod-shaped material rolls into the guide shell 5, and the two limiting plates 2 17 block the second rod-shaped material.

[0029] Then, the electric push rod 212 is activated. The telescopic end of the electric push rod 212 drives the push plate 13 to slide along the guide shell 5, thereby pushing the rod-shaped material into the feed hole of the CNC machine tool 1. Subsequently, the telescopic end of the electric push rod 212 is controlled to drive the push rod to reset. When the telescopic ends of the two electric push rods 320 are controlled to reset, the limiting plate 15 and the limiting plate 27 both move downward. The limiting plate 27 gradually releases the obstruction of the rod-shaped material. After the limiting plate 15 and the limiting plate 27 are reset, the rod-shaped material rolls downward along the support shell 4 and the extension shell 6. The limiting plate 15 blocks the bottommost rod-shaped material again, thereby realizing that the rod-shaped material is pushed into the feed hole of the CNC machine tool 1 in sequence, improving the stability of feeding.
