Description

Technical Field

[0001] This utility model relates to the field of mechanical processing automation technology, and in particular to an automatic feeding device. Background Technology

[0002] In the field of lathe machining, spring components face numerous challenges during processing due to their unique structure and material properties. Currently, the machining of spring components mainly relies on manual operation, presenting the following technical problems:

[0003] 1. Difficulty in machining the head of spring parts: The head of spring parts is usually quite rough and needs to be machined to achieve a smooth and aesthetically pleasing finish. However, due to the irregular shape of the spring, it cannot be stably clamped directly using conventional fixtures. Auxiliary tools such as ferrules must be used for fixation, which increases the complexity of machining.

[0004] 2. Insufficient precision of manual clamping: Springs have elastic deformation characteristics, and it is difficult to ensure consistency when manually using a master clamping set, which easily leads to clamping errors, resulting in unstable machining accuracy and affecting product quality.

[0005] 3. Low production efficiency: The existing processing method relies on manual operation. The clamping process is cumbersome and time-consuming. One operator can usually only be responsible for one machine tool, which limits the production capacity and makes it difficult to meet the needs of mass production. The labor cost is also high.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] Example:

[0030] This embodiment describes the structure of an automatic feeding device.

[0031] like Figure 1 As shown, Figure 1This is a three-dimensional structural diagram of an automatic feeding device according to this utility model. The automatic feeding device includes: a vibratory feeder 1, a feeding device, and a pneumatic robotic arm picking device 12. The vibratory feeder 1 is connected to the feeding device, and the pneumatic robotic arm picking device 12 is located in front of the feeding device. The material is fed into the feeding device via the vibratory feeder 1. The orientation of the spring material has been processed by the vibratory feeder before being fed into the feeding device, and the spring material is oriented and conveyed into the feeding device. After being discharged from the feeding device, the material is taken out by the pneumatic robotic arm picking device 12 and placed into the fixture of the lathe spindle 7 for stable clamping. The lathe's cutting tool device 8 processes the head of the spring material. This process achieves automated feeding, clamping, and head processing, reducing manual intervention and improving processing accuracy and production efficiency.

[0032] like Figure 2 , 3 As shown, Figure 2 This is a schematic diagram of the automatic feeding device of this utility model. Figure 3 This is a schematic diagram of the first ejector pin and the second ejector pin in this utility model. In a preferred embodiment, the feeding device includes a first feeding device 3 and a second feeding device 9. The first feeding device 3 is located above the second feeding device 9, and both the first feeding device 3 and the second feeding device 9 are driven by a pneumatic device 4.

[0033] The first feeding device 3 is equipped with a vertically penetrating feeding channel 19 to ensure that the direction of the material does not change during the feeding process. The feeding channel 19 corresponds to the feeding port of the vibrating plate 1, and the material enters the feeding channel after passing through the vibrating plate.

[0034] To control the feeding order and frequency of spring components and to facilitate subsequent component clamping for accuracy, a first feeding ejector pin 14 and a second feeding ejector pin 15 are provided in the first feeding device 3. The first feeding ejector pin 14 is located above the second feeding ejector pin 15. The first feeding ejector pin 14 and the second feeding ejector pin 15 are connected vertically by a connecting rod 16. The cylinder device 4 drives the connecting rod 16 to move the first feeding ejector pin 14 and the second feeding ejector pin 15 back and forth, pushing the component to the second feeding device 9. A feeding hole 17 is provided on the second feeding ejector pin 15.

[0035] Under the action of the first and second feeding ejector pins, the material enters the first feeding device sequentially through the vibrating plate, one at a time, to ensure feeding frequency and improve clamping efficiency and accuracy. The working principle of the first and second feeding ejector pins: When the first part enters the feeding channel 19, under the action of the cylinder device 4, the first feeding ejector pin 14 and the second feeding ejector pin 15 are moved to one side of the feeding channel 19. However, since the length of the second feeding ejector pin 15 is designed to be longer than that of the first feeding ejector pin 14, the second feeding ejector pin 15 is not completely away from the feeding channel 19. Therefore, the first part entering the feeding channel 19 falls onto the second feeding ejector pin 15. The feeding device operates continuously and automatically. Then, the cylinder device drives the first feeding ejector pin 14 and the second feeding ejector pin 15 to reset. At the same time, the second part enters the feeding channel 19 and is held by the first feeding ejector pin 14. The first part on the second feeding ejector pin 15 falls through the feeding hole 17 to the second feeding device 9 as the second feeding ejector pin moves. The first and second feeding ejector pins, in conjunction with the cylinder device, repeat the above movements to ensure that the spring parts are discharged one by one, which not only allows for accurate clamping after material extraction but also improves the discharge efficiency.

[0036] The structural design of the first feeding device solves the problems of operational complexity and difficulty in ensuring clamping accuracy in the existing technology, where spring parts still need to be fixed with auxiliary tools such as male and female sleeves during clamping. This utility model ensures that the direction of the spring parts does not change during the feeding process from the vibrating plate to the outlet by setting a vertically penetrating feeding channel in the first feeding device, thus ensuring the accuracy and consistency of clamping, ensuring the precision of material processing, and improving product quality.

[0037] like Figure 4 , 5 As shown, Figure 4 This is a schematic diagram of the cam structure and the rotatable workstation in this utility model. Figure 5 This is a schematic diagram of another angle showing the cam structure and the rotatable station in conjunction. In a preferred embodiment, to facilitate material handling and improve the speed and accuracy of clamping after discharge, a second feeding device is provided below the first feeding device. The second feeding device 9 includes a rotatable station 6 and a cam structure 5. The rotatable station 6 is mounted on mounting plates 18 on both sides of the rotatable station 6 via bearings, and the rotatable station can rotate along the bearings. The rotatable station 6 is located on the cam structure 5. When the cylinder device 4 drives the cam structure 5 to move, the cam structure 5 pushes the rotatable station 6 to flip. A material receiving port 10 is provided on the rotatable station 6 to receive the material discharged from the first feeding device 3.

[0038] In the preferred embodiment, the rotatable station 6 can be rotated 90° by the cam structure 5. After rotation, the material pick-up port 10 faces the pneumatic manipulator material pick-up device 12. Driven by the X-axis motor 11 and the Z-axis motor 13, the pneumatic manipulator material pick-up device 12 sends the workpiece to the fixture of the lathe spindle 7 and holds it stably so that the subsequent cutting tool device can process the workpiece.

[0039] Working principle: After being processed by the vibratory feeder 1, the material enters the feeding channel 19 in an orderly manner. The first feeding ejector pin 14 and the second feeding ejector pin 15 work together with the cylinder device 4 to control the material to be discharged one by one. The material falls into the picking port 10 on the rotatable station 6 one by one. The cylinder device 4 drives the cam structure 5 to move backward. The rotatable station 6 rotates 90° in the opposite direction to the cam structure 4. The picking port 10 is facing the pneumatic manipulator picking device 12. Driven by the motor, the pneumatic manipulator picking device 12 sends the material to the lathe for clamping and completes the processing of the material.

[0040] In this invention, a second feeding device is installed below the first feeding device, and a material pick-up port is set on a rotatable station, located directly below the feeding channel. After being fed by the first feeding device, the material falls precisely and stably into the pick-up port, where it is accurately gripped by a pneumatic robotic arm and transported to a lathe for further processing. The entire process is automated; the material's orientation remains unchanged from feeding to clamping, and the clamping position is precisely determined, ensuring consistent positioning of all materials. This improves the consistency of material clamping and consequently enhances the consistency of material processing quality.

[0041] In the preferred embodiment, the feeding device also has a sensor that detects whether there are any materials in the feeding device. When there are materials, the vibratory feeder stops moving; when there are no materials, the vibratory feeder moves to feed materials, thereby improving feeding efficiency.

[0042] In this invention, the positional arrangement of the feeding device, the pneumatic robotic arm picking device, and the lathe can be rationally arranged according to the actual production space. This invention does not impose any restrictions on the layout position, and the coordination between each action is controlled by the connected CNC lathe signal program. The use of the cylinder device, the pneumatic robotic arm picking device, the lathe spindle, and the cutting tool device is well known to those skilled in the art, and no improvements have been made in this invention; therefore, their detailed structures are not described in detail or shown in the accompanying drawings.

[0043] This utility model solution has been put into use and successfully applied to the mass production and processing of spring parts. Actual production statistics show that using this device increases production efficiency by 30%, reduces manpower by 80%, enhances the company's market competitiveness, and significantly improves production efficiency. Compared to existing technologies that rely on manual operation and have limited capacity, this utility model's automated continuous processing not only greatly saves labor costs but also meets the needs of large-scale production.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
