Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool loading devices, and more specifically, to a CNC machine tool loading structure that can be automatically positioned. Background Technology

[0002] CNC machine tools, also known as CNC lathes or computer numerical control lathes, are currently the most widely used and prevalent type of CNC machine tool in China. Patent publication number CN220825708U discloses an automatically positioned CNC machine tool loading structure, relating to the field of CNC machine tool loading. To address the problem that existing CNC machine tool loading devices, due to the symmetrical fixing of third connecting plates at both ends of the sliding rod, prevent the placement box from smoothly reaching the first transport plate, leading to loading failures, an automatically positioned CNC machine tool loading structure is proposed. This structure includes a frame mounted on the outer wall of the CNC machine tool. A material storage device is located on the side of the frame away from the CNC machine tool. Moving devices are mounted on the upper surfaces of both sides of the frame, each equipped with a loading device. Conveying devices are mounted on the inner walls of both sides of the frame, each equipped with a feeding device. The automatic positioning structure of the CNC machine tool ensures that the feeding process can proceed normally and will not fail. The fixed block automatically positions the raw material, ensuring the stability of the feeding process and thus ensuring the normal operation of the CNC machine tool.

[0003] While existing technologies can achieve stable feeding and automatic positioning of materials through multi-stage conveying, certain problems still exist in actual use. For example, during the process of materials entering the storage bin from the inlet, the height difference between the outlet and the material can cause the electric telescopic rod inside the storage bin to collide, deform, or be damaged. Additionally, the position of the material inside the bin may change, further affecting the intended placement of the material during feeding and reducing the positioning effect. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an automatically positioning CNC machine tool loading structure. It can effectively buffer and decelerate materials when they enter the storage bin, preventing overall deformation and excessive positional changes that could affect positioning due to height differences. It can also protect the internal electric telescopic rod, and the buffer component can be adjusted in length to accommodate materials of different widths, thus achieving effective buffering and deceleration, thereby improving the overall applicability of the device.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An automatic positioning CNC machine tool loading structure includes a storage bin, a feeding port on the side of the storage bin, a loading platform fixedly installed at the bottom of the feeding port, an inclined plate fixedly installed on one side of the loading platform, a fixing plate fixedly installed on the outer side of the inclined plate, an arc-shaped guide rod fixedly installed on the surface of the fixing plate, a spring movably sleeved on the surface of the arc-shaped guide rod, and a buffer assembly fixedly connected to one end of the spring.

[0009] Furthermore, an electric telescopic rod is fixedly installed on the inner wall of the storage box below the inclined plate, and a pusher plate is fixedly installed on the outer end of the electric telescopic rod. A spring door is rotatably installed inside the storage box on the left side of the same horizontal plane as the pusher plate.

[0010] Furthermore, several rotating columns are rotatably mounted on the top of the loading platform, and the outer edge of the loading platform is set with a rounded corner structure.

[0011] Furthermore, the buffer assembly includes a limiting rotating rod, a connecting rod fixedly installed on the outer side of the bottom end of the limiting rotating rod, a guide ring fixedly installed on the outer end of the connecting rod, a telescopic box fixedly installed on the top end of the limiting rotating rod, an installation ring fixedly installed on the outer wall of the telescopic box, a screw rotatably installed inside the installation ring, a transmission plate threaded on the surface of the screw, a sleeve rod fixedly connected to one end of the transmission plate, an outer end rod integrally formed on the outer end of the sleeve rod, and a roller rotatably installed inside the outer end of the outer end rod.

[0012] Furthermore, the guide ring is movably sleeved on the surface of the arc-shaped guide rod, the side of the guide ring and one end of the spring are fixedly connected to each other, and the limiting rotating rod is rotatably installed inside the inclined plate.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution utilizes a loading platform and rotating column to allow materials to enter the storage box more effectively without causing significant friction with the surface of the loading platform, thus ensuring the material surface remains intact. Furthermore, the inclined plate above the electric telescopic rod effectively protects the electric telescopic rod, preventing materials from falling and causing collision damage to the electric telescopic rod.

[0018] (2) This solution utilizes a buffer component that works with an arc-shaped guide rod and a spring to provide horizontal resistance, thereby effectively slowing down and buffering the material falling along the inclined plate, preventing it from entering the storage bin too quickly, causing deformation of itself and impact deformation of the inner wall of the storage bin.

[0019] (3) This solution utilizes the buffer component to adapt to the falling workpieces of different widths by changing its own length, which improves the applicability of the device itself. Secondly, the buffer component can be designed symmetrically to make the falling workpiece move down along the center line of the inclined plate, ensuring the correction of the initial position and further improving the practicality of the device.

[0028] Example 1:

[0029] Please see Figure 1-3 An automatic positioning CNC machine tool loading structure includes a storage box 1, a feeding port 2 on the side of the storage box 1, a loading platform 3 fixedly installed at the bottom of the feeding port 2, an inclined plate 4 fixedly installed on one side of the loading platform 3, a fixing plate 5 fixedly installed on the outer side of the inclined plate 4, an arc-shaped guide rod 6 fixedly installed on the surface of the fixing plate 5, a spring 7 movably sleeved on the surface of the arc-shaped guide rod 6, and a buffer assembly 8 fixedly connected to one end of the spring 7.

[0030] It should be noted that, apart from the loading platform 3 and the inclined plate 4 and the related structures provided on the surface of the inclined plate 4, all the rest in this application are existing components in the prior art documents. Therefore, the related connecting parts and structural functions inside and outside the existing components are consistent with those in the prior art documents. So the prior art will not be described in detail in this application.

[0031] An electric telescopic rod 9 is fixedly installed on the inner wall of the storage box 1 below the inclined plate 4. A pusher plate 10 is fixedly installed on the outer end of the electric telescopic rod 9. A spring door 11 is rotatably installed on the left side of the same horizontal plane as the pusher plate 10 inside the storage box 1. Several rotating columns 301 are rotatably installed on the top of the loading platform 3. The outer edge of the loading platform 3 is set as a rounded corner structure.

[0032] Specifically, the rounded corner structure at the outer end of the top surface of the loading platform 3 can better reduce surface loss during the upward movement of materials. Similarly, the rotating column 301 can make the movement of materials smoother and more unobstructed. Finally, the inclined plate 4 can make the materials mainly subject to gravity during the falling process, and the buffer component 8 can slow down the speed on both sides to ensure the integrity of the material's shape and the integrity of the inside of the storage box 1.

[0033] The buffer assembly 8 includes a limiting rotating rod 801. A connecting rod 802 is fixedly installed on the outer side of the bottom end of the limiting rotating rod 801. A guide ring 803 is fixedly installed on the outer end of the connecting rod 802. A telescopic box 804 is fixedly installed on the top end of the limiting rotating rod 801. An installation ring 805 is fixedly installed on the outer wall of the telescopic box 804. A screw 806 is rotatably installed inside the installation ring 805. A transmission plate 809 is threaded onto the surface of the screw 806. A sleeve rod 8010 is fixedly connected to one end of the transmission plate 809. An outer end rod 8011 is integrally formed on the outer end of the sleeve rod 8010. The internal rotating part is equipped with a roller 8012. The guide ring 803 is movably sleeved on the surface of the arc-shaped guide rod 6. The side of the guide ring 803 and one end of the spring 7 are fixedly connected to each other. The limiting rotating rod 801 is rotatably installed inside the inclined plate 4. One end of the screw 806 is fixedly installed with a rotating wheel 807. The surface of the telescopic box 804 is provided with a sliding groove 808 on the same side as the transmission plate 809. The transmission plate 809 is slidably installed inside the sliding groove 808. There are four buffer components 8. The four buffer components 8 are divided into two groups. The two groups of buffer components 8 are movably installed on the left and right sides of the inclined plate 4, respectively.

[0034] Specifically, the guide ring 803 is sleeved on the surface of the arc-shaped guide rod 6 to limit the overall rotation trajectory of the buffer assembly 8, so that it can be horizontally fixed by the thrust of the spring 7 in the stationary state, thus slowly blocking the passing material. The roller 8012 allows the material to pass through better by rolling, preventing excessive surface contact friction from affecting the falling of the material. Finally, the mounting ring 805 limits the rotation of the screw 806, ensuring stable transmission between it and the transmission plate 809.

[0035] The working principle of this utility model is as follows: First, adjust the outer end rod 8011 to a suitable position according to the size of the material. Rotate the rotating wheel 807 to drive the screw 806, so that the transmission plate 809 drives the sleeve rod 8010 to extend from the inside of the sliding groove 808, driving the outer end rod 8011 to move until the distance between the two outer end rods 8011 on opposite sides matches the width of the material. When the material enters the storage box 1 from the feed port 2, the material moves to the top surface of the inclined plate 4 along the rotation of the rotating column 301. During the process, when it contacts the outer end rod 8011, the outer end rod 8011 is pressured to drive the guide ring 803 to compress the spring 7, and then rotates around the center of the limiting rotating rod 801. The material always moves against the outer wall of the roller 8012. Because of the obstruction of the outer end rod 8011, the material speed is reduced, and it finally enters the storage box 1 along the inclined plate 4. Then it is pushed out by the pusher plate 10.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
