Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a machine tool feeding device. Background Technology

[0002] In the field of machinery manufacturing, machine tools, as core processing equipment, directly affect production efficiency and product quality through their processing efficiency, workpiece accuracy, and ease of operation. The loading and unloading processes in machine tool processing, as crucial steps connecting the pre- and post-processing stages, have become important factors restricting the improvement of overall machine tool processing efficiency due to their degree of automation and process rationality.

[0003] In traditional machine tool processing, workpiece unloading and loading often employ a "step-by-step independent operation" mode: after a workpiece is finished, the operator must first manually or with simple tools remove the finished old workpiece from the machine tool's processing area. After the old workpiece is cleaned up, the new workpiece to be processed is then moved to the processing area and positioned. This process involves a significant time interval between unloading and loading, and requires manual intervention throughout. This not only causes the machine tool to be in a prolonged downtime during workpiece changeover, but also significantly reduces equipment utilization. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a machine tool feeding device that significantly improves overall processing efficiency, is particularly suitable for batch workpiece processing scenarios, and effectively enhances equipment utilization.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A machine tool processing loading device includes a worktable with a loading window in the middle. A rotating plate is provided inside the loading window, and the rear end of the rotating plate is rotatably connected to the left and right rear ends of the loading window. A first loading port is provided in the middle of the rotating plate. Trapezoidal plates are fixedly connected to the lower sides of both ends of the rotating plate. A collection box is fixedly connected to the lower side of the worktable. A first opening is provided on the upper front side of the collection box. A first pull-out box is movably connected to the inner side of the first opening. The lower side of the trapezoidal plate is close to the upper side of the first pull-out box. Movable components for connecting to the collection box are provided on both the left and right sides of the first pull-out box. A second pull-out box is movably connected to the lower front side of the collection box. A fixed plate is fixedly connected to the front side of the first pull-out box. An arc-shaped plate is installed on the upper rear side of the fixed plate through a connecting component.

[0006] Furthermore, the movable component includes fixed ears fixedly connected to the left and right sides of the front end of the first pull-out box, and movable rods fixedly connected to the rear sides of the upper and lower ends of the fixed ears, with the rear end of the movable rods passing through the inside of the collection box.

[0007] Furthermore, a first electric push rod is installed inside the left end of the collection box, and the drive end of the first electric push rod is fixedly connected to the middle of the rear side of the fixing ear.

[0008] Furthermore, the connecting assembly includes a first connecting plate fixedly connected to the rear side of the upper end of the fixed plate, a second connecting plate rotatably connected to the rear end of the first connecting plate, a first connecting member fixedly connected to the rear end of the second connecting plate, a second connecting member installed on the inner side of the first connecting member, and an arc-shaped plate fixedly connected to the rear end of the second connecting member.

[0009] Furthermore, a second opening is provided at the center of the front end of the first connecting plate, and a spring is provided inside the second opening.

[0010] Furthermore, the upper end of the spring is fixedly connected to the lower front end of the second connecting plate, and the lower end of the spring is fixedly connected to a protruding plate, the front end of which is fixedly connected to the middle of the rear side of the fixed plate.

[0011] Furthermore, a second discharge port is provided at the middle of the rear end of the first pull-out box, and support plates are fixedly connected to the lower sides of both the left and right ends of the workbench.

[0012] Furthermore, side plates are fixedly connected to the upper sides of both the left and right ends of the workbench, and a second electric push rod is fixedly connected to the middle of the side plate. A pad is fixedly connected to the driving end of the second electric push rod.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the unloading of old workpieces and loading of new workpieces are integrated. The core action of moving the first pull-out box via the first electric push rod simultaneously completes multiple key operations: as the first pull-out box moves backward, the new workpiece is smoothly transported to the processing area via the arc-shaped plate, and the trapezoidal plate is pushed to flip the rotating plate, opening the unloading window so that the processed old workpiece falls into the first pull-out box along the inclined rotating plate. The entire process requires no additional steps, significantly shortening workpiece changeover time and avoiding the time interval of "unloading first, then loading" in traditional processing. This significantly improves overall processing efficiency, making it particularly suitable for batch workpiece processing scenarios and effectively increasing equipment utilization.

[0014] 2. In this utility model, the operator only needs to place the new workpiece in advance on the arc plate. The subsequent "loading-unloading-resetting" process is automatically driven by the electric push rod. There is no need for manual handling or adjustment of the workpiece position, which reduces the labor intensity and safety risks in the manual handling process. The finished old workpiece automatically falls into the first pull box and slides along the inclined surface inside the box to the front area. The operator can take out the old workpiece after the device is reset, avoiding the trouble of sorting out the old workpiece scattered, and further improving the convenience of operation.

[0017] 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.

[0018] Reference Figures 1-5This utility model provides an embodiment of a machine tool processing feeding device, including a worktable 1. A feeding window 2 is provided in the middle of the worktable 1. A rotating plate 3 is provided inside the feeding window 2. The rear end of the rotating plate 3 is rotatably connected to the left and right sides of the rear end of the feeding window 2. A first feeding port 4 is provided in the middle of the rotating plate 3. Trapezoidal plates 5 are fixedly connected to the lower sides of both the left and right ends of the rotating plate 3. A collection box 6 is fixedly connected to the lower side of the worktable 1. A first opening 7 is provided on the front upper side of the collection box 6. A first pull-out box 8 is movably connected to the inner side of the first opening 7. The lower side of the trapezoidal plate 5 is in close contact with the upper side of the first pull-out box 8. The lower front side of the collection box 6 is movably connected to the upper side of the first pull-out box 8. The first pull-out box 8 is connected to a second pull-out box 20. A fixed plate 12 is fixedly connected to the front side of the first pull-out box 8. An arc-shaped plate 15 is installed on the upper rear side of the fixed plate 12 through a connecting component. Fixed ears 9 are fixedly connected to the left and right sides of the front end of the first pull-out box 8. Movable rods 10 are fixedly connected to the rear sides of the upper and lower ends of the fixed ears 9. The rear end of the movable rods 10 passes through the inside of the collection box 6. A first electric push rod 11 is installed inside the left end of the collection box 6. The drive end of the first electric push rod 11 is fixedly connected to the middle of the rear side of the fixed ears 9. A second discharge port 19 is opened in the middle of the rear end of the first pull-out box 8. Support plates 23 are fixedly connected to the lower sides of both the left and right ends of the workbench 1.

[0019] The operator places the new workpiece to be processed on the arc plate 15 in advance to prepare for subsequent loading. The operator then activates the first electric push rod 11 installed inside the left end of the collection box 6. The drive end of the first electric push rod 11 retracts backward, causing the fixed ear 9, which is fixedly connected to it, to move backward. Since the fixed ear 9 is fixed to the left and right sides of the front end of the first pull-out box 8, the first pull-out box 8 moves backward synchronously with the fixed ear 9. During this process, the rear ends of the movable rods 10, which are fixedly connected to the upper and lower ends of the fixed ear 9, pass through the inside of the collection box 6. The cooperation structure between the movable rods 10 and the collection box 6 effectively restricts the movement trajectory of the first pull-out box 8, ensuring that the first pull-out box 8 always maintains a stable linear movement. When the first pull-out box 8 moves backward, the fixed plate 12, which is fixedly connected to its front side, moves synchronously. The rear side of the upper end of the fixed plate 12 is connected to the arc plate 15 through a connecting assembly. The first connecting plate 13 in the connecting assembly is fixed to the fixed plate 12 and moves backward together with the fixed plate 12, thereby driving the arc plate... As the first pull-out box 8 moves backward, the new workpiece placed on the arc plate 15 is smoothly transported to the processing area above the workbench 1. During the backward movement of the first pull-out box 8, its rear end gradually contacts the rear end of the trapezoidal plate 5, which is fixedly connected to the lower sides of the left and right ends of the rotating plate 3. As the first pull-out box 8 continues to move backward, the trapezoidal plate 5 drives the rotating plate 3 to rotate downward around its rear end under the action of gravity. The front end of the rotating plate 3 gradually tilts downward, causing the unloading window 2 opened in the middle of the workbench 1 to gradually open. At this time, the old workpiece is released, and under the action of gravity, the old workpiece slides down along the plane of the tilted rotating plate 3 and falls into the first pull-out box 8 below through the opened unloading window 2. Since the first pull-out box 8 has an inclined structure inside, the old workpiece slides along the inclined surface to the front end area of ​​the first pull-out box 8, completing the unloading and collection of the old workpiece. The first pull-out box 8 continues to move backward until the arc plate 15 accurately transports the new workpiece to the processing area of ​​the workbench 1, clamps and fixes the new workpiece, and completes the loading and positioning of the new workpiece.

[0020] During the workpiece processing, a large amount of processing debris is generated. Since the rotating plate 3 has a first discharge port 4 in the middle, these debris will fall into the collection box 6 fixedly connected to the lower side of the worktable 1 through the first discharge port 4 during the processing, and finally settle in the second pull-out box 20 movably connected to the lower front side of the collection box 6. When the debris in the second pull-out box 20 accumulates to a certain amount, the operator can directly pull out the second pull-out box 20 from the collection box 6 to clean the debris. After cleaning, the second pull-out box 20 is put back into the collection box 6 to realize convenient collection and treatment of debris.

[0021] Reference Figures 1-5The connecting assembly includes a first connecting plate 13 fixedly connected to the rear side of the upper end of the fixed plate 12, a second connecting plate 14 rotatably connected to the rear end of the first connecting plate 13, a first connecting member 21 fixedly connected to the rear end of the second connecting plate 14, a second connecting member 22 installed on the inner side of the first connecting member 21, an arc-shaped plate 15 fixedly connected to the rear end of the second connecting member 22, a second opening 16 opened in the middle of the front end of the first connecting plate 13, a spring 17 provided in the inner side of the second opening 16, the upper end of the spring 17 fixedly connected to the lower side of the front end of the second connecting plate 14, a protruding plate 18 fixedly connected to the lower end of the spring 17, and the front end of the protruding plate 18 fixedly connected to the middle of the rear side of the fixed plate 12.

[0022] After the new workpiece is fixed, the device enters the component reset stage to prepare for the next processing cycle. The drive end of the first electric push rod 11 extends, pushing the fixing ear 9 and the first pull-out box 8 forward to reset. During the forward movement of the first pull-out box 8, the arc plate 15 gradually tilts downward under the contact with the new workpiece. The tilting of the arc plate 15 causes the second connecting plate 14 to rotate around the rear end of the first connecting plate 13. The lower front end of the second connecting plate 14 generates a pulling force on the spring 17 in the connecting assembly, causing the spring 17 to be stretched and store elastic potential energy. After the curved plate 15 completely passes over the new workpiece, the obstruction force it experiences disappears, the spring 17 releases its elastic potential energy, pulls the second connecting plate 14 to rotate in the opposite direction, and drives the curved plate 15 back to its initial horizontal state, completing the reset of the curved plate 15. At the same time, as the first pull-out box 8 continues to reset forward, its front end gradually contacts the front end of the trapezoidal plate 5, pushing the trapezoidal plate 5 to move upward, which in turn drives the rotating plate 3 to rotate upward around its rear end until the rotating plate 3 returns to a horizontal state, closes the feeding window 2 again, and the entire device completes the reset, waiting for the next processing instruction.

[0023] Reference Figures 1-5 Side plates 24 are fixedly connected to the upper sides of both the left and right ends of the worktable 1. A second electric push rod 25 is fixedly connected to the middle of the side plate 24. A pad 26 is fixedly connected to the driving end of the second electric push rod 25.

[0024] The second electric push rod 25 drives the pad 26 to move towards the center to fix the workpiece to be processed. The workpiece is then processed by external equipment. When the processing is completed and unloading and loading are required, the new workpiece is placed on the arc plate 15 for loading.

[0025] Working Principle: The second electric push rod 25 drives the pad 26 to move towards the center, fixing the workpiece to be processed. External equipment is then used for processing. After processing, when unloading and loading are required, a new workpiece is placed on the arc-shaped plate 15. Then, the first electric push rod 11 is activated, driving the first pull-out box 8 to move backward. Fixed ears 9 and movable rods 10 on the left and right sides of the first pull-out box 8 are used to maintain the stability of its movement. During the backward movement of the first pull-out box 8, the first connecting plate 13 and the second connecting plate 14 drive the arc-shaped plate 15 and the workpiece backward, sending the workpiece to the processing area. During this process, the rear end of the first pull-out box 8 moves backward and gradually contacts the rear end of the trapezoidal plate 5, causing the rotating plate 3 to rotate around its rear end. This causes the front end of the rotating plate 3 to tilt downward, opening the unloading window 2. At this time, the second electric push rod 25 releases the unloaded workpiece. The workpiece falls into the first pull-out box 8 along the plane of the rotating plate 3. It moves to the front end of the first pull-out box 8 via the inclined surface of the first pull-out box 8. Then, the first pull-out box 8 continues to move backward until the workpiece is delivered to the processing area by the arc plate 15 and fixed by the second electric push rod 25 and the pad 26. Then, the first electric push rod 11 drives the first pull-out box 8 to move forward. During the movement, the arc plate 15 will gradually tilt downward, thereby driving the second connecting plate 14 to rotate around the front end of the first connecting plate 13, thereby stretching the spring 17. After the arc plate 15 passes the workpiece, the spring 17 pulls the second connecting plate 14 to rotate, so that the arc plate 15 returns to its original position. As the first pull-out box 8 returns to its original position, the front end of the first pull-out box 8 contacts the front end of the trapezoidal plate 5, so that the rotating plate 3 returns to its original position, which is convenient for subsequent processing. The debris generated during processing is collected in the second pull-out box 20 through the first discharge port 4 for convenient subsequent centralized cleaning.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
