Description

Technical Field

[0001] This utility model relates to the field of CNC machining auxiliary equipment technology, specifically a CNC machine product loading and unloading device. Background Technology

[0002] In the field of machinery manufacturing, CNC machine tools have become core equipment for parts processing due to their high precision and high efficiency. With the rapid development of the manufacturing industry, the demand for automation in CNC machining is increasing. The loading and unloading process, as a crucial step in the CNC machining process, directly impacts the overall production progress. Initially, CNC loading and unloading relied entirely on manual operation. Operators had to manually place the products to be processed into the machine tool's machining area and then remove the processed products after machining. This method was limited by the speed of manual operation, resulting in extremely low efficiency, and required operators to frequently approach the running machine tool, posing significant safety hazards.

[0003] To address the shortcomings of manual loading and unloading, semi-automatic loading and unloading equipment has emerged. This type of equipment is typically installed outside the CNC machine tool, transporting products via conveyor belts, from which manual assistance is required to transfer the products inside the machine tool. However, this method still has significant drawbacks: firstly, the equipment occupies a large amount of external space, making it unsuitable for compact production layouts; secondly, manual intervention is still required for the transfer of products between the outside and inside of the machine tool, failing to achieve full automation; thirdly, the lack of precise positioning mechanisms results in insufficient positioning accuracy when products are placed in the processing area, affecting processing quality; and fourthly, the loading and unloading actions are difficult to coordinate with the machine tool's processing rhythm, easily leading to excessively long waiting times and limited improvements in production efficiency. Existing technologies have also seen some attempts at in-machine loading and unloading, but these often suffer from complex structures and poor compatibility, only adapting to specific CNC machine tool models and specific product specifications. Furthermore, the connection between feeding and unloading is not smooth enough, failing to effectively solve the core pain points of positioning accuracy and operational efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1As shown, a CNC machine tool in-machine product loading and unloading device includes a frame 1, a gripper mechanism 2 inside the frame 1, an automatic hopper mechanism 3 below the gripper mechanism 2, a fixture 4 outside the automatic hopper mechanism 3, a cutter head 5 above the gripper mechanism 2, and a leveling and buffering mechanism 6 on the cutter head 5. The frame 1 serves as the base of the entire device, supporting and fixing key components such as the gripper mechanism 2, the automatic hopper mechanism 3, and the fixture 4, ensuring the stability and reliability of the overall structure. During CNC machine tool processing, the gripper mechanism 2 automatically picks up the product to be processed from the automatic hopper mechanism 3 and accurately places it on the fixture 4. After processing, the product is removed from the fixture 4 and returned to the automatic hopper mechanism 3, realizing automatic product loading and unloading. The automatic hopper mechanism 3 has a large storage capacity, reducing the number of manual loading operations. Its layered design facilitates management and product handling. A sealing device effectively prevents debris generated during processing from entering the hopper. It stores both finished and unfinished products, and automated control enables orderly loading and unloading, reducing manual intervention and improving production efficiency. The sealing device ensures a clean processing environment, enhancing product quality. The fixture 4 provides stable support and fixation for the product during CNC machining, ensuring machining accuracy and product quality. The cutter head 5 serves as the mounting base for the leveling and buffering mechanism 6, providing stable support and rotation. After the product is placed on the fixture 4, the leveling and buffering mechanism 6 levels the product, eliminating surface unevenness and stress concentration, improving machining accuracy and product quality. Automated loading and unloading significantly reduces manual intervention and waiting time, increasing the machining efficiency and production capacity of the CNC machine tool. The automated loading and unloading process reduces the possibility of human error, while the leveling and buffering mechanism 6 improves the stability and consistency of product processing, thereby enhancing product quality.

[0020] like Figure 3As shown, the material gripper mechanism 2 includes a vertical slide rail 21 and a vertical slide cylinder 22. A fixed frame 23 is slidably mounted on one side of the vertical slide cylinder 22, and a fixed arm 24 extends outward from the outside of the fixed frame 23. A suction cup 25 is mounted at the end of the fixed arm 24. A horizontal plate 26 is provided above the vertical slide cylinder 22, and a horizontal slide cylinder 27 is provided on the horizontal plate 26. A horizontal slide rail 28 is provided on one side of the horizontal slide cylinder 27, and a flat plate 29 is slidably connected to the horizontal slide rail 28. The vertical slide rail 21 provides a stable linear motion track. The vertical slide cylinder 22 is driven by a servo motor to achieve high-precision positioning of the fixed frame 23 in the vertical direction, ensuring that the suction cup 25 can accurately reach the product gripping position. The fixed frame 23 and the vertical slide cylinder 22 are connected to the vertical slide cylinder 22. The slide cylinder 22 is tightly connected to ensure stability during movement and prevents shaking. The suction cup 25 is made of highly elastic material, which can generate a large suction force to ensure that the product will not slip during gripping. The horizontal plate 26 serves as the mounting base for the horizontal slide cylinder 27, providing stable support and ensuring that the horizontal slide cylinder 27 remains stable during movement. The horizontal slide rail 28 provides a stable linear motion track, ensuring that the flat plate 29 remains smooth during movement and is not prone to jamming or jumping. Through precise motion control in the vertical and horizontal directions, the gripper mechanism 2 can achieve high-precision positioning and stable gripping of the product, ensuring accurate placement and movement of the product during CNC machine tool processing.

[0021] like Figure 3 and Figure 4 As shown, the automatic hopper mechanism 3 includes a hopper base plate 31, on which a linear slide rail 32 is mounted. A slide cylinder 33 is mounted on one side of the linear slide rail 32, and two limiting hoppers 34 are mounted above the linear slide rail 32. The limiting hoppers 34 are directly and fixedly connected to the hopper base plate 31 via a first guide shaft 36. A protective plate 37 is mounted on the other side of the automatic hopper mechanism 3, and a first compression spring 38 is mounted on the outer wall of the protective plate 37. A positioning pin 35 is mounted on the inner bottom surface of the limiting hoppers 34. The linear slide rail 32 adopts a rolling friction design, combining dynamic friction and static friction. With minimal differences and no slippage, the precise movement of the limiting hopper 34 is ensured when driven by the slide cylinder 33. The limiting hopper 34 is used to orderly store products to be processed or already processed. After being fixed by the guide shaft, it cooperates with the slide cylinder 33 to achieve rapid positioning and transfer of materials. The protective plate 37 and the spring form a buffer system to protect the stability of the hopper mechanism during high-speed movement or emergency stop, while reducing noise. The positioning pin 35 is inserted into the corresponding hole of the material or fixture 4 to ensure the consistency of the position each time and avoid processing errors caused by position deviation.

[0022] like Figure 5As shown, the leveling and buffering mechanism 6 includes a second guide shaft 61, on which a screw 62 is fixed, and a second compression spring 63 is provided below the guide shaft. The precise cooperation between the second guide shaft 61 and the screw 62 ensures that the leveling head moves vertically without deviation. Combined with the adaptive pressure control of the spring, the flatness of the product surface is guaranteed.

[0023] like Figure 2 As shown, a speed regulating valve 14 is provided on the inner wall of the equipment frame 1, and a bamboo tube 15 is connected to the speed regulating valve 14; the speed regulating valve 14 can adjust the water output rate according to the washing requirements of the logo to ensure that qualified products can be successfully washed out.

[0024] like Figure 1 As shown, the bottom of the equipment frame 1 is provided with an adjustable support foot 12, which is threadedly connected to the equipment frame 1. The bottom of the adjustable support foot 12 is provided with an anti-slip pad 13; on smooth or sloping ground, it prevents the equipment from sliding due to vibration or external force, ensuring operational safety.

[0025] like Figure 1 As shown, a protective cover plate 11 is provided on the outside of the equipment frame 1. The protective cover plate 11 is detachably connected to the equipment frame 1. The protective cover plate 11 is connected to the equipment frame 1 by a buckle, bolt or quick-release structure, and can be installed or removed without tools. The cover plate prevents external objects from hitting the precision parts inside the equipment, avoiding the decrease in accuracy or failure of function caused by collision.

[0026] Working principle: The manual feeder places 30 layers of material into the limiting hopper 34. The suction cup 25 picks up the material pieces from the hopper and moves them onto the fixture 4 via the XYZ axes of the CNC machine. Then, the buffer mechanism flattens the product on the fixture 4. When the product is placed on the fixture 4, the limiting hopper 34 will be closed by a cylinder. Then, the CNC machine processes the product and uses the bamboo tube 15 to wash out the outline of the logo. The suction cup 25 picks up the processed product and puts it into the hopper for unloading. When the hopper is full of 30 pieces, the manual feeder moves the hopper out for unloading.

[0027] In summary, this CNC machine tool's in-machine product loading and unloading equipment achieves automatic product conveying through the gripper mechanism 2 and the automatic hopper mechanism 3, replacing manual operation, reducing frequent picking and placing, avoiding defects caused by human error, improving production efficiency, saving labor costs, and solving the problems of low efficiency and high safety hazards of manual operation. Since all components are assembled on the equipment frame 1, the structure is compact and the action coordination is strong. The feeding, positioning, and picking actions are smoothly connected and can be precisely matched with the processing rhythm of the CNC machine tool, reducing waiting time and significantly improving production efficiency.
