Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, and more particularly to an automatic loading device for a multi-functional numerically controlled lathe. Background Art

[0002] As a modern processing device, numerically controlled lathes play an important role in the machinery manufacturing industry due to their high precision and efficiency. Such lathes are usually equipped with multi-station turrets or power turrets and can perform complex machining tasks, such as machining of complex workpieces like straight cylinders, inclined cylinders, arcs, and threads, grooves, and worms. To achieve an automated processing process, numerically controlled lathes are often equipped with grippers (or robotic arms) to complete the grasping and placement of materials.

[0003] In the traditional processing process, the robotic arm moves the cylindrical parts to be processed from the loading area to the clamping and positioning mechanism on the lathe. After clamping, the lathe tool starts to machine the parts. After machining is completed, the robotic arm removes the finished products and grabs new parts to be processed from the loading area, repeating this process. In this mode, although the basic functions of automation are achieved, there are certain limitations. Specifically, currently, most multi-functional automatic loading systems can only place a limited number of parts to be processed on the loading table. In addition, due to the limitation of the telescopic length of the robotic arm, multiple loading tables cannot be closely arranged, which further limits the continuous working ability of the system. When the materials on the loading table are exhausted, the machine needs to be stopped for manual replenishment of new parts to be processed, which not only increases the workload of the operator but also reduces the overall production efficiency.

[0004] Therefore, in view of the above problems, there is an urgent need to propose an automatic loading device for a multi-functional numerically controlled lathe, which is of great significance for improving the overall performance and production efficiency of numerically controlled lathes. Summary of the Utility Model

[0005] In order to overcome the above-mentioned disadvantages existing in the prior art, the utility model provides an automatic loading device for a multi-functional numerically controlled lathe, which is of great significance for improving the overall performance and production efficiency of numerically controlled lathes.

[0006] The technical solution of the present utility model is: a multifunctional numerically controlled lathe automatic loading device, which includes a machine frame, a robotic arm, a first connecting seat, an annular chain plate conveyor, a second connecting seat, a grasping seat, a positioning rod and a placing table. A robotic arm is arranged on one side of the machine frame, and first connecting seats are arranged on both sides of the end of the robotic arm. An annular chain plate conveyor is arranged on the machine frame. A plurality of second connecting seats are evenly spaced on the conveyor belt of the annular chain plate conveyor. A positioning rod is arranged around the top of each second connecting seat. A placing table is inserted between the four positioning rods. At least four holes for placing materials are provided on the placing table, and grasping seats for grasping materials are inserted on both first connecting seats.

[0007] Preferably, it further includes a first guide rod, a first spring and a wedge block. First guide rods are arranged on both sides of the first connecting seat. Wedge blocks that are clamped with the adjacent grasping seats are slidably arranged on the two first guide rods, and a first spring is arranged between the wedge block and the adjacent first guide rod.

[0008] Preferably, it further includes a wedge plate, a second guide rod and a second spring. A second guide rod is arranged on one side of the first connecting seat. A wedge plate is slidably arranged on the second guide rod. A second spring is arranged between the wedge plate and the first connecting seat. Both ends of the wedge plate are inclined planes and are respectively in contact and cooperation with the adjacent wedge blocks.

[0009] Preferably, it further includes a fan. A fan is arranged at the end of the robotic arm between the two first connecting seats.

[0010] Preferably, it further includes a wind guide box. A wind guide box is arranged at the air outlet of the fan. The two sides of the wind guide box are inclined plane air outlets, and the two inclined plane air outlets respectively correspond to the grasping seats on both sides.

[0011] Preferably, the structure between the second connecting seat and the placing table is the same as that between the first connecting seat and the grasping seat.

[0012] Beneficial effects: 1. The present utility model transports the materials on the placing table through the annular chain plate conveyor, so that the distance between the placing table and the robotic arm is changed by moving. Coupled with the continuous transportation of the annular chain plate conveyor, the supply of materials is continuous. At the same time, considering the working time required by the robotic arm itself, it is ensured that the time for manually placing materials on the placing table is sufficient, thus avoiding the situation of forced shutdown for feeding due to the limitation of the working range of the robotic arm.

[0013] 2. The present utility model realizes the quick and simple replacement of the grasping seat and the placing table through the cooperation of the wedge plate and the wedge block, making the overall operation process simpler and more efficient, and thus improving the overall working efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The embodiments of the utility model will be described in detail below with reference to the attached drawings.

[0022] Embodiment: A multifunctional numerically controlled lathe automatic loading device, as Figures 1-4As shown in the figure, it includes a machine frame 1, a robotic arm 2, a first connecting seat 3, an endless chain plate conveyor 4, a second connecting seat 5, a gripping seat 6, a positioning rod 13, and a placement table 14. The machine frame 1 serves as the basic support structure of the entire device. A robotic arm 2 is fixedly arranged on the left side of the machine frame 1, and the robotic arm 2 can flexibly control the gripping of materials. First connecting seats 3 are arranged on both the left and right sides of the end of the robotic arm 2. An endless chain plate conveyor 4 is fixedly arranged on the top of the machine frame 1. The endless chain plate conveyor 4 is mainly responsible for the transportation of materials, enabling the distance between the materials and the robotic arm 2 to change, providing a distance convenient for the robotic arm 2 to grip the materials, and then cooperating with the telescopic operation of the robotic arm 2 itself to achieve the gripping of materials. Six second connecting seats 5 are evenly spaced on the conveyor belt of the endless chain plate conveyor 4. One positioning rod 13 is arranged at each of the four corners on the top of the second connecting seat 5. A placement table 14 is inserted between the four positioning rods 13, making the disassembly and assembly of the placement table 14 more convenient. Four holes for placing materials are provided on the placement table 14. The setting of the holes can ensure the stable placement of materials and can also ensure the transportation of a large amount of materials at one time, thereby improving the work efficiency accordingly. Moreover, gripping seats 6 for gripping materials are inserted on both of the first connecting seats 3. The gripping seats 6 can cooperate with the flexible telescopic operation of the robotic arm 2 itself to achieve the precise gripping of materials, thus ensuring the automatic loading of materials.

[0023] As Figure 2 and Figure 3 shown in the figure, it further includes a first guide rod 7, a first spring 8, and a wedge block 9. Two first guide rods 7 are arranged on both the left and right sides of the first connecting seat 3. Wedge blocks 9 that are slidably arranged on the first guide rods 7 on both sides and are clamped with the adjacent gripping seats 6 are provided. The wedge blocks 9 can clamp and fix the positions of the gripping seats 6, and a first spring 8 is arranged between the wedge blocks 9 and the adjacent first guide rods 7, which can deform in cooperation with the operation of the wedge blocks 9 to provide a push for the subsequent reset of the wedge blocks 9.

[0024] As Figure 2 and Figure 3 shown in the figure, it further includes a wedge plate 10, a second guide rod 11, and a second spring 12. A second guide rod 11 is arranged at the rear side of the first connecting seat 3. A wedge plate 10 is slidably arranged on the second guide rod 11. A second spring 12 is arranged between the wedge plate 10 and the first connecting seat 3. The left and right ends of the wedge plate 10 are both inclined surfaces and are respectively in contact and cooperation with the adjacent wedge blocks 9 to push the wedge blocks 9 to release the clamping restriction on the gripping seats 6, so as to facilitate the quick replacement of the gripping seats 6. At the same time, the structure between the second connecting seat 5 and the placement table 14 is the same as the structure between the above-mentioned first connecting seat 3 and the gripping seat 6, using the same principle and components, and can also achieve the quick removal and replacement of the placement table 14.

[0025] As Figure 5As shown in the figure, it further includes a fan 15. The fan 15 is disposed at the end of the robotic arm 2 and is located between two first connection seats 3.

[0026] As Figure 5 shown in the figure, it further includes an air guide box 16. The air guide box 16 is disposed at the air outlet of the fan 15. The left and right sides of the air guide box 16 are both inclined air outlets, and the two inclined air outlets respectively correspond to the grasping seats 6 on both sides, so as to remove the debris on the surface of the grasping seats 6 and ensure the cleanliness of the material.

[0027] When the device needs to be used, ensure that the frame 1 is on a stable workbench. Then place the material to be used in the hole of the placement table 14. Start the annular chain conveyor 4, and drive the second connection seat 5 thereon to move in a circular trajectory through the annular chain conveyor 4. Then the second connection seat 5 transports the placement table 14, so that the placement table 14 can reach the robotic arm 2. Then start the robotic arm 2, and grasp the material on the placement table 14 through the grasping seat 6 on the robotic arm 2. During this process, the fan 15 can be started at the same time. The air guide box 16 is filled with air through the fan 15, and then the air outlets on both sides of the air guide box 16 blow on the grasping seats 6 on both sides to blow off some of the debris attached to the grasping seats 6, so as to ensure the cleanliness of the grasped material. In addition, because the operation of the robotic arm 2 is very flexible, and with two grasping seats 6, it can cooperate to complete the material grasping with higher efficiency. Here, because of the setting of the annular chain conveyor 4, the distance between the placement table 14 and the robotic arm 2 can be changed by moving, and it cooperates with the continuous transportation of the annular chain conveyor 4, thus avoiding the situation of stopping work for feeding due to the insufficient length of the robotic arm 2, effectively improving the overall work efficiency; if the model of the transported material is replaced, the staff needs to replace the placement table 14 for placing the material and the grasping seat 6 for grasping the material accordingly. First, the staff pushes the wedge plate 10, so that the wedge plate 10 slides on the second guide rod 11 close to the first connection seat 3 or the second connection seat 5. Then the second spring 12 deforms, and then the two ends of the wedge plate 10 will contact the corresponding wedge blocks 9 on both sides as it moves, and push the wedge blocks 9 on both sides through the inclined surfaces at both ends, so that the wedge blocks 9 slide on the first guide rod 7 away from the first connection seat 3 or the second connection seat 5, and the first spring 8 deforms accordingly. When the wedge blocks 9 on both sides are separated from the corresponding grasping seat 6 or placement table 14, the grasping seat 6 or placement table 14 to be replaced is released from the restriction of the wedge blocks 9. Then the staff can perform the corresponding replacement operation. In addition, the staff will release the wedge plate 10 later, and the corresponding first spring 8 and second spring 12 will reset accordingly, so that the above-mentioned components will return to their original positions. After that, if it is necessary to install the replacement components, repeat the above operations for installation.

[0028] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural or equivalent process transformation made by using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
