Description

Technical Field

[0001] This utility model relates to a feeding device, and more particularly to a clamping feeding device. Background Technology

[0002] In many applications, it is necessary to machine circular sheets of material. Circular sheets refer to discs with a certain thickness, such as circular magnet raw materials. (See also...) Figure 12 Before magnetization, precision machining (such as grinding, chamfering, drilling, etc.) is required. The current mainstream feeding scheme is a vibratory feeder with a linear feeding track. However, in actual production, problems such as jamming and stacking frequently occur, leading to increased equipment downtime and decreased processing yield, which has become a key bottleneck restricting production capacity. On the other hand, the feeding method using intelligent robotic arms is more expensive, more difficult to operate, requires high skills from operators, and requires a certain amount of installation space.

The rotation axis of the clamping plate is parallel to the ejection direction of the ejection mechanism. The clamping plate has a tendency to move closer to the clamping groove 6a to clamp the sheet material 9 in the clamping groove 6a. The discharge end of the feeding channel 20 is provided with a contact block for contacting the clamping plate to open the clamping plate outward.

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] See Figures 1-11 This utility model provides a clamping and feeding device, including a support plate 1, which can be fixedly connected to a machine tool (for machining) and serves as a mounting carrier. A feeding mechanism 2 and a transverse moving mechanism are mounted on the support plate 1.

[0036] The feeding mechanism 2 is used to feed the sheet material 9. A feeding channel 20 is formed on the feeding mechanism 2 to allow the sheet material 9 to pass through. In this embodiment, the feeding channel 20 is arc-shaped and its discharge end is vertical, so that the sheet material 9 can be discharged in a vertical state. Its inlet end is used to connect with the vibrating plate. The sheet material enters the feeding channel 20 in a state parallel to the horizontal plane.

[0037] The lateral movement mechanism includes a first slide block 31 and a first drive device 32 for driving the first slide block 31 to move laterally. A baffle plate is provided on the first slide block 31. The baffle plate can block the discharge port at the lower end of the feeding channel 20. After the material is received, the discharge port is blocked to prevent the sheet material from continuing to slide down.

[0038] A dual-axis moving mechanism is installed on the lateral moving mechanism. The dual-axis moving mechanism can move as a whole with the lateral moving mechanism. It includes a mounting base, which can realize longitudinal horizontal movement and vertical lifting. The longitudinal horizontal movement is horizontal movement that is perpendicular to the lateral horizontal movement, and the longitudinal lifting is movement that is perpendicular to the horizontal plane. The lateral horizontal movement, longitudinal horizontal movement and vertical lifting are all perpendicular to each other.

[0039] Specifically, the dual-axis moving mechanism includes a longitudinal moving mechanism and a vertical lifting mechanism mounted on the longitudinal moving mechanism. The longitudinal moving mechanism includes a second slide 41 and a second drive device 42 for driving the second slide 41 to move longitudinally and horizontally. The vertical lifting mechanism includes a third slide 51 and a third drive device 52 for driving the third slide 51 to move vertically and vertically. The mounting base is mounted on the third slide. Both the second and third drive devices are cylinders, which are low in cost, fast in response, and easy to operate.

[0040] A clamping mechanism 6 is installed on the mounting base. The clamping mechanism 6 is used to clamp the sheet material 9 at the outlet end of the feeding channel 20 and move it onto the chuck of the machine tool located at the lower end of the support plate 1.

[0041] Meanwhile, an ejector mechanism is also installed on the mounting base. The ejector mechanism can eject the sheet material in the clamping mechanism, so that the sheet material 9 in the clamping mechanism enters the clamping range of the machine tool chuck, ensuring the accurate positioning of the sheet material 9. The ejection direction of the ejector mechanism is perpendicular to the sheet material 9 in the clamping mechanism 6. The ejection direction of the ejector mechanism in this application is parallel to the longitudinal horizontal movement direction of the mounting base, which facilitates the overall installation on the machine tool and ensures the feeding accuracy. The ejector mechanism also includes a fourth slide 71, an ejector rod 711, and an ejector cylinder 72. The fourth slide 71 can realize longitudinal horizontal movement. The ejector rod 711 is detachably installed on the fourth slide 71, and its axis is parallel to the sliding direction of the fourth slide. Different specifications of ejector rods can be replaced according to different sheet materials. The output end of the ejector cylinder 72 is connected to the fourth slide and is used to drive the fourth slide to move longitudinally horizontally, so that the ejector rod moves closer to or away from the clamping mechanism to realize ejection.

[0042] This application sets up a transverse moving mechanism and a dual-axis moving mechanism to form a three-axis moving system, which can achieve precise positioning of sheet material in three-dimensional space. Its structure is compact, manufacturing cost is low, and operational stability is good, enabling rapid and accurate sheet material transfer. A baffle plate is set on the transverse moving mechanism. When the clamping mechanism finishes receiving the material and moves away from the lower outlet of the feeding channel 20, the baffle plate automatically blocks the outlet to prevent the sheet material from slipping. This linkage eliminates the need for additional parts and operations, improving structural compactness, simplifying the process, and increasing efficiency. The clamping mechanism 6 can stably clamp the sheet material 9, improving transfer accuracy. Combined with the precise ejection of the ejector mechanism, it ensures the sheet material smoothly enters the chuck, improving clamping accuracy. It enables the sheet material to be quickly and accurately positioned to the machine tool chuck, significantly improving processing efficiency and product quality. There is no jamming, high operational reliability, reduced manual intervention, and automated, efficient operation, improving overall production efficiency.

[0043] Specifically, the clamping mechanism 6 is provided with a clamping groove 6a. The upper end and both ends of the clamping groove 6a are open. The upper end is open and is located directly below the outlet end of the feeding channel when receiving material, connected to the lower end of the feeding channel 20, so that the sheet material 9 can slide smoothly into the clamping groove 6a. The front end is open, with one end facing the direction of the machine tool chuck, used to push the sheet material to the machine tool chuck, and the other end away from the direction of the machine tool chuck, used for the action of the ejector mechanism. This end can be completely open or have a separate ejector hole. A clamping plate is hinged to one side of the clamping groove 6a, and the rotation axis of the clamping plate is... The line is parallel to the ejection direction of the ejection mechanism. In this application, it is perpendicular to the sheet material. The clamping plate has a tendency to move closer to the clamping groove 6a, thereby clamping the sheet material 9 in the clamping groove 6a. At the same time, a contact block is provided at the discharge end of the feeding channel 20. When the clamping mechanism 6 moves closer to the feeding channel 20 in a horizontal direction, the contact block can contact the upper end of the clamping plate and open the contact block of the clamping plate outward, so that the sheet material can smoothly enter the high clamping groove. Therefore, in order to achieve better opening, a contact part 621 is provided at the top of the clamping plate for contacting the contact block.

[0044] The clamping plate structure generates continuous inward pressure under the action of elasticity. After the sheet material enters the clamping groove, it is automatically clamped during movement. At the same time, when the clamping mechanism is horizontally close to the discharge port, the clamping plate (contact part) can contact the contact block, physically opening the clamping plate and making the clamping groove form a resistance-free material receiving port. When the clamping mechanism is horizontally away from the discharge port, the clamping plate separates from the contact block and automatically closes under the action of elasticity, achieving stable clamping of the sheet material and ensuring that it does not shift during movement. The linkage of the clamping plates is achieved mechanically, with a compact structure, no need for additional cylinders or motors or other power sources, low cost, high operational stability, and low failure rate.

[0045] In this embodiment, the clamping mechanism 6 includes a material placement seat 61, the top surface of which forms a material placement surface 610. A first side of the material placement surface 610 is provided with an abutment surface 611, which is the side close to the baffle plate and forms an L-shape. A clamping plate 62 is hinged to the second side of the material placement seat 61. The inner wall of the clamping plate 62 forms a clamping surface. A clamping groove 6a is formed between the clamping surface, the material placement surface 610, and the abutment surface 611. At the same time, an elastic component 63 is provided on the material placement seat 61. This elastic component can be a compression spring or a torsion spring, which causes the clamping surface to tend to move closer to the clamping groove 6a to achieve clamping of the sheet material. Its structure is simple and compact, with low manufacturing cost and good operational reliability. In this application, the material placement surface 610 is U-shaped or V-shaped, which can achieve stable support for the sheet material and has an automatic centering function with high positioning accuracy.

[0046] In order to reduce the rotation stroke and improve the smoothness of operation, in this embodiment, a limiting part 612 is formed at the end of the material placement seat 61. The limiting part 612 can contact the clamping plate 62, thereby limiting the clamping plate and preventing the clamping plate from rotating excessively. On the one hand, it can prevent the clamping plate from being damaged due to excessive rotation, and on the other hand, it can ensure that the upper end of the clamping plate can smoothly contact the contact block to realize the automatic opening of the clamping plate and ensure its stable clamping.

[0047] To ensure the stability of the sheet material in the clamping slot when the clamping mechanism moves horizontally and disengages from the feeding channel 20, this embodiment provides a baffle surface 311 and abutment surface 312 on the baffle plate. The baffle surface 312 is a horizontal surface that blocks the outlet of the feeding channel 20, preventing the sheet material from detaching. The abutment surface 312 is located at the end of the baffle surface and is a vertical surface parallel to the horizontal direction, flush with the conveying surface of the feeding channel 20. During the horizontal movement of the clamping mechanism, the abutment surface 312 contacts the clamping mechanism. Since the clamping plate is not fully closed (clamped) at this time, it acts as a positioning surface to prevent the sheet material from deflecting or falling until the clamping plate is fully closed, ensuring smooth clamping of the sheet material. This prevents the sheet material from deflecting during the clamping process of the clamping plate, greatly improving the clamping accuracy and reliability of the sheet material, providing a solid foundation for subsequent processing steps, ensuring a dual improvement in production efficiency and product quality, and preventing jamming.

[0048] To reduce production costs and improve clamping accuracy, the sheet material can be appropriately pushed by the ejector mechanism (ejector rod) during receiving, so that the sheet material fits against the surface and forms a stable initial position, ensuring the clamping accuracy of the sheet material.

[0049] In this embodiment, the feeding channel 20 is arc-shaped, and the sheet material at its discharge end is perpendicular to the ejection direction of the ejection mechanism.

[0050] In this application, limit structures are provided at the limit positions of the horizontal moving mechanism, the longitudinal horizontal moving mechanism, and the vertical lifting mechanism. The position of the limit structure is adjustable and can be adjusted according to different workpieces, which provides good flexibility and adapts to various processing needs, while effectively avoiding mechanical damage caused by exceeding the limit.

[0051] The following is a brief description of the working method of the clamping and feeding device of this utility model. (See attached document for details.) Figure 11 ;

[0052] Step 1: Reset. At this time, the clamping mechanism is located at the discharge port directly below the feeding channel 20, and the clamping plate 62 is in a fully open state. The sheet material in the feeding channel 20 naturally slides into the clamping groove under the action of gravity.

[0053] Step 2: The lateral moving mechanism moves horizontally, driving the baffle plate and clamping mechanism to move horizontally in sync. The baffle plate blocks the outlet of the feeding channel 20 to ensure that no material is discharged. The clamping plate 62 gradually closes to clamp the sheet material. During this process, the back surface 312 serves as a support to ensure that the sheet material does not come off during clamping.

[0054] Step 3: After reaching the horizontal limit position, the longitudinal movement mechanism is activated, driving the clamping mechanism to move horizontally and longitudinally away from the feeding channel;

[0055] Step 4: After reaching the horizontal and longitudinal limit positions, the vertical lifting mechanism is activated, and the clamping mechanism moves vertically downward to the lower limit position. At this time, the clamping plate 62 is coaxial with the machine tool's chuck.

[0056] Step 5: After reaching the lower limit position, the longitudinal movement mechanism starts in reverse, driving the clamping mechanism to move horizontally and longitudinally back, moving towards the machine tool chuck to the limit position;

[0057] Step Six: After reaching the limit position, the push rod pushes the sheet material and pushes it into the slot of the machine tool chuck to achieve automatic feeding;

[0058] Then, perform the reset in the reverse order (steps six through one). Figure 11 The red arrow in the middle indicates the reset action; during the reset process in step one, the upper end of the clamping plate 62 contacts the contact block and is in the open state.

[0059] This utility model relates to a clamping and feeding device, which is equipped with a transverse moving mechanism and a dual-axis moving mechanism to form a three-axis moving system. This system enables precise positioning of sheet materials in three-dimensional space. It features a compact structure, small size, low manufacturing cost, and good operational stability, allowing for rapid and accurate sheet material transfer. A baffle plate is installed on the transverse moving mechanism. When the clamping mechanism finishes receiving the material and moves away from the lower outlet of the feeding channel, the baffle plate automatically blocks the outlet, preventing the sheet material from slipping. This linkage eliminates the need for additional parts and operations, improving structural compactness, simplifying the process, and increasing efficiency. The clamping mechanism provides stable clamping of the sheet material, improving transfer accuracy. Combined with the precise ejection of the ejector mechanism, it ensures the sheet material smoothly enters the chuck, further enhancing clamping precision. This utility model's clamping and feeding device enables rapid and precise positioning of sheet materials to the machine tool chuck, significantly improving processing efficiency and product quality. It eliminates jamming, has high operational reliability, reduces manual intervention, achieves automated and efficient operation, and improves overall production efficiency.

[0060] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
