Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a feeding device. Background Technology

[0002] Impellers are commonly used in fluid machinery such as pumps, turbines, and compressors. They have complex shapes and are made of various materials, including metals, plastics, and composites. Manufacturing impellers requires high-precision machining, especially the blades, which may involve processes such as casting and CNC machining. To enable rapid impeller machining, impeller processing equipment is rapidly evolving towards higher precision, intelligence, green manufacturing, and flexibility.

[0003] To facilitate rapid material loading, reduce manual intervention, lower production costs, and ensure product quality, automatic feeding devices are typically used to feed the raw materials for processing impellers. However, since impellers may have different sizes, shapes, and materials, if the feeding device cannot be flexibly adjusted, it needs to be readjusted when changing products, which increases downtime and costs. For example, the unloading device needs to be readjusted to fit impellers of different sizes, and the robotic arm used for loading also needs to be reprogrammed to ensure it can pick up the raw materials, all of which affect production efficiency.

[0004] Therefore, it is necessary to provide a feeding device to address the aforementioned technical problems.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0043] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0044] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0046] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0047] Reference Figures 1-4 As shown, the feeding device in this embodiment includes a base 1, a conveying mechanism 2, a discharging mechanism 3, and a driving mechanism 4. The conveying mechanism 2 is mounted on the base 1; the discharging mechanism 3 is positioned above the conveying mechanism 2 and includes a base plate 31 mounted on the conveying mechanism 2, a rotating component 32 rotatably mounted on the base 1, a support rod 33 fixedly mounted on the rotating component 32, and a first pallet 34 and a second pallet 35 fixedly mounted on the base plate 31. The first pallet 34 and the second pallet 35 are respectively provided with different first grooves 341 and second grooves 351, and the support rod 33 is sequentially inserted into the first groove 341 and the second groove 351. The driving mechanism 4 is linked to the conveying mechanism 2 and is used to drive the conveying mechanism 2 to transport the discharging mechanism 3. Specifically, in this embodiment, there are three support rods 33, which are arranged in an equilateral triangle to form a placement space where impeller blanks can be placed so that they fall out during the conveying process of the discharging mechanism 3. In this embodiment, the support rod 33 can rotate along its axial direction under the action of the rotating member 32, so that the size of the placement space can be changed to accommodate impeller blanks of different sizes, thereby ensuring production efficiency and reducing production costs.

[0048] The specific method for adjusting the position of the support rod 33 is as follows: rotate the first support plate 34. Since the support rod 33 is inserted into the first groove 341 and the first groove 341 on the first support plate 34 is a curved groove, when the first support plate 34 is rotated, the position of the support rod 33 can change along the extension direction of the first groove 341, thus changing the size of the placement space. Of course, the first groove 341 in this application can also be a straight groove or a combination of curved and straight grooves, and the second groove 351 can also be one of curved grooves, straight grooves, or a combination of both, all of which should be within the protection scope of this application.

[0049] To lock the position of the support rod 33 using the first groove 341 and the second groove 351, ensuring that the position of the support rod 33 does not change, refer to Figure 3 , Figure 4As shown, on the plane where the first groove 341 is located, the projection of the second groove 351 partially coincides with the first groove 341. In this embodiment, the outer wall of the support rod 33 abuts against the inner wall of the first groove 341 and the inner wall of the second groove 351, respectively. Based on this design, the four points on the support rod 33 are limited and cannot rotate with the rotating member 32.

[0050] Preferably, when using a robotic arm for feeding, to ensure automatic feeding of the impeller material without adjusting the robotic arm parameters, refer to... Figure 2 , Figure 5 , Figure 6 As shown, the feeding device in this embodiment also includes an adjustment mechanism 8 mounted on the base 1. The adjustment mechanism 8 is used to adjust the position of the feeding mechanism 3. The adjustment mechanism 8 can be a drive structure with linear drive function, such as a cylinder or hydraulic cylinder. When the feeding mechanism 3 moves onto the adjustment mechanism 8, its position can be adjusted to match the gripping path of the robotic arm.

[0051] To facilitate the transfer of material from conveyor mechanism 2 to unloading mechanism 3, refer to... Figure 2 , Figure 5 As shown, the conveying mechanism 2 in this embodiment includes a driving sprocket 21, a driven sprocket 22, and a chain 23 meshing with the driving sprocket 21 and the driven sprocket 22, all linked to the driving mechanism 4. The feeding mechanism 3 is mounted above the chain 23. When the output shaft of the driving mechanism 4 rotates, it drives the driving sprocket 21 to rotate, thereby driving the chain 23 to rotate. Under the drive of the chain 23, the driven sprocket 22 also rotates, so that the chain 23 can rotate under the action of the driving mechanism 4. Since the feeding mechanism 3 is placed above the chain 23, it can move along the direction of movement of the chain 23 under the drive of the chain 23.

[0052] To facilitate the feeding mechanism 3, the feeding device in this embodiment also includes a rolling unit mounted on the base 1. The rolling unit surrounds the chain 23, and its top is flush with the top of the chain 23. According to this design, when the feeding mechanism 3 moves under the drive of the chain 23, the bottom plate 31 can contact the rolling unit, thereby ensuring that the feeding mechanism 3 always remains relatively horizontal and does not vibrate, thus preventing the impeller material from falling out of the placement space.

[0053] To ensure that the unloading mechanism 3 can be placed on the rolling unit during the conveying process, so that the rolling unit can provide stable support without excessively affecting the conveying of the unloading mechanism 3, refer to... Figure 5As shown, the rolling unit in this embodiment includes a first rolling unit 51 and a second rolling unit 52. The first rolling unit 51 and the second rolling unit 52 are arranged in an elongated oval shape, and the interval between the first rolling unit 51 and the second rolling unit 52 is less than or equal to the length of the base plate 31. According to this design, when the feeding mechanism 3 runs on the rolling unit, the base 1 can be located on the first rolling unit 51 and the second rolling unit 52.

[0054] Specifically, in order to facilitate the rolling of roller 501 unit on the lower surface of base 1 and ensure smooth and stable conveying by feeding mechanism 3, refer to Figure 5 As shown, the rolling unit in this embodiment includes rollers 501 and bullseye wheels 502. The axis of rollers 501 is set in the horizontal direction, and the rollers 501 are arranged in a straight line. The bullseye wheels 502 are arranged in a semi-circular arc at least in part.

[0055] Preferably, refer to Figure 5 As shown, the feeding device in this embodiment also includes a first limiting plate 61 installed above the chain 23 and two second limiting plates 62 installed on the outside of the rolling unit and symmetrically arranged. The gap between the two second limiting plates 62 and the first limiting plate 61 is less than the length of the base plate 31. According to this design, the base plate 31 can be limited by the first limiting plate 61 and the second limiting plate 62, thereby limiting the feeding mechanism 3 to prevent it from shifting its position on the rolling unit or even falling off the rolling unit.

[0056] Optional, refer to Figure 3 , Figure 6 As shown, the feeding device in this embodiment also includes a lifting mechanism 7. The lifting mechanism 7 includes a driving component 71, a lifting plate 72 linked to the driving component 71, two lifting rods 73 fixedly installed on the lifting plate 72, and two lifting blocks 74 fixedly installed on the two lifting rods 73 respectively. The lifting blocks 74 are located above the base 1 and below the second support plate 35. Since the distance between the two lifting blocks 74 is greater than the width of the base plate 31 and the diameter of the first support plate 34, and the distance between the two lifting blocks 74 is less than the diameter of the second support plate 35, when the lifting blocks 74 move upward under the drive of the lifting rods 73, they can drive the second support plate 35 to move upward, thereby pushing the impeller blank upward. The driving component 71 can be a linear drive mechanism with linear drive function, such as a Z-axis servo, stepper, cylinder, magnetic drive, or hydraulic drive, which is acceptable to those skilled in the art. Based on this design, when enough impeller blanks are placed on the feeding mechanism 3, the impeller blanks can be transported to the next process by means of a robotic arm or manual labor. During this process, the impeller blanks can be lifted upward by the lifting mechanism 7 to match the material grabbing path of the robotic arm or manual labor, thereby reducing the feeding time.

[0057] Preferably, to facilitate automatic sensing, impeller blanks are placed in the placement space, as per [reference]. Figure 2 As shown, the feeding device in this embodiment also includes a sensing mechanism 9. The sensing mechanism 9 includes a first fixed rod 91 and a second fixed rod 92 mounted on the base 1, and a transmitter 93 and a receiver 94 respectively mounted on the first fixed rod 91 and the second fixed rod 92. The distance between the first fixed rod 91 and the second fixed rod 92 is greater than the maximum dimension of the base plate 31 in the horizontal direction. According to this design, the transmitter 93 emits photoelectric light, and the receiver 94 determines whether it receives the photoelectric light. When it receives the photoelectric light, the feeding mechanism 3 does not have a sufficient number of impeller blanks. When it does not receive the photoelectric light, the feeding mechanism 3 has a sufficient number of impeller blanks.

[0058] In order to cooperate with the lifting mechanism 7 and to lift the impeller blank into place, refer to Figure 2 , Figure 6 As shown, in this embodiment, the transmitter 93 and receiver 94 are at the same horizontal height. There are two sets of transmitters 93 and receivers 94. The height of the uppermost transmitter 93 and receiver 94 is less than or equal to the height of the support rod 33, and the height of the lowermost transmitter 93 and receiver 94 is greater than the height of the second support plate 35. When the uppermost receiver 94 receives the photoelectric signal emitted by the transmitter 93, the lifting mechanism 7 does not lift the impeller blank into position. When the uppermost receiver 94 receives the photoelectric signal emitted by the transmitter 93, the lifting mechanism 7 lifts the impeller blank into position.
