[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] See Figure 1-2As shown, a machining feeding device includes a support frame 1, on which a lifting mechanism 2 and a rotating mechanism 3 are provided; a bearing plate 4 is provided on the rotating mechanism 3, and the bearing plate 4 can rotate 180° each time driven by the rotating mechanism 3; a pair of storage mechanisms 5 for placing materials are provided on the bearing plate 4. In use, the storage mechanisms 5 rotate with the bearing plate 4, so that one set of storage mechanisms 5 is always in the workpiece feeding position (supplying material to the machine tool), and the other set of storage mechanisms 5 is always in the workpiece loading position (loading material into the storage mechanism 5); two sets of first clearance holes 41 are opened on the bearing plate 4 located directly below each set of storage mechanisms 5, but not limited to two sets, other sets can also be set as long as the requirements are met; the lifting mechanism 2 is located at the feeding position, and the upper end of the lifting mechanism 2 can lift the material in the storage mechanism 5 that has rotated to the feeding position after passing through the first clearance holes 41.

[0031] Further, see Figure 3 As shown, in this embodiment, the rotating mechanism 3 includes a turntable assembly 31. The lower end of the turntable assembly 31 is connected to a first drive motor 33 via a first synchronous pulley assembly 32. During installation, after the turntable assembly 31 is mounted on the support frame 1, the bearing plate 4 is fixed on the turntable of the turntable assembly 31, and the first drive motor 33 is fixed on the support frame 1 via a corresponding motor support seat. During use, the first drive motor 33 drives the turntable of the turntable assembly 31 to rotate via the first synchronous pulley assembly 32, thereby driving the bearing plate 4 to rotate.

[0032] Further, see Figure 4 As shown, in this embodiment, the storage mechanism 5 includes a fixed plate 51, a movable plate 52 is disposed above the fixed plate 51, and a first guide shaft 53 is disposed along the edge of the movable plate 52. The lower end of the first guide shaft 53 is fixed to the fixed plate 51, and the upper end of the first guide shaft 53 is connected together by a fixed frame 54. During feeding, the materials to be processed are placed sequentially on the movable plate 52. During feeding, the lifting mechanism 2 lifts the materials sequentially via the movable plate 52. In this embodiment, in order to enable the upper end of the lifting mechanism 2 to lift the movable plate 52, a second clearance hole 511 is provided on the fixed plate 51, and the second clearance hole 511 is located below the movable plate 52. During lifting, see... Figure 2 As shown, the upper end of the lifting mechanism 2 passes through the first clearance hole 41 and then through the second clearance hole 511 to lift the movable plate 52.

[0033] In this embodiment, after the storage mechanism 5 is loaded onto the support plate 4, a corresponding second clearance hole 511 is formed on the fixing plate 51 located directly above each group of first clearance holes 41. That is, each group of fixing plates 51 has two groups of second clearance holes 511. At this time, the size of the second clearance hole 511 is not smaller than the size of the corresponding first clearance hole 41. Of course, the number of second clearance holes 511 is only one implementation method and is not intended to limit the scope of this application. In actual installation, only one group of second clearance holes 511 can be formed. In this case, the two groups of first clearance holes 41 below each group of fixing plates 51 are located within the range of the second clearance holes 511.

[0034] Furthermore, in this embodiment, see Figure 3-4 As shown, to prevent the storage mechanism 5 from shifting upwards on the support plate 4 during the lifting of materials within the storage mechanism 5, a through hole 512 is provided on the fixing plate 51, and a pin 42 corresponding to the through hole 512 is provided on the support plate 4. The upper outer surface of the pin 42 is provided with external threads; see also Figure 1 As shown, after the storage mechanism 5 is loaded onto the support plate 4, the pin 42 is inserted into the corresponding through hole 512, and then the nut is screwed in and tightened. It should be noted that, with the above locking method, when loading materials into the storage mechanism 5, the storage mechanism 5 can be locked onto the support plate 4, and then the materials can be loaded into the storage mechanism 5 through the upper opening of the storage mechanism 5 in sequence; or the materials can be loaded into the storage mechanism 5 first, and then the storage mechanism 5 and the materials can be placed together on the support plate 4 and locked.

[0035] Further, see Figure 5As shown, in this embodiment, the lifting mechanism 2 includes a connecting plate 21. A rotatable lead screw 22 passes through the connecting plate 21 via a corresponding bearing seat. The lower end of the lead screw 22 is connected to a second drive motor 24 via a second synchronous pulley assembly 23. A lifting plate 25 is provided on the lead screw 22 above the connecting plate 21. Lifting rods 26 are provided on the lifting plate 25. The lifting rods 26 are divided into two groups, and a lifting block 27 is provided above each group of lifting rods 26. During installation, the connecting plate 21 is fixed on the support frame 1, and the upper end of the lead screw 22 is connected to the corresponding bearing seat. The seat is rotatably mounted on the support frame 1, and the upper end of the lifting rod 26 can slide through the support frame 1. At this time, each set of lifting blocks 27 is located directly below a set of the first clearance holes 41. During lifting, the second drive motor 24 drives the lead screw 22 to rotate through the second synchronous pulley assembly 23, thereby driving the lifting plate 25 to move up and down, thereby driving the lifting rod 26 to move up and down, thereby enabling the lifting blocks 27 to pass through the first clearance holes 41 and then through the second clearance holes 511 to lift the movable plate 52, thereby lifting the material.

[0036] In this embodiment, see further. Figure 5 As shown, in order to ensure the stability of the vertical displacement of the lifting plate 25, a second guide shaft 28 is provided on the connecting plate 21. The second guide shaft 28 can slide through the lifting plate 25 and its upper end is fixedly connected to the support frame 1.

[0037] Further, see Figure 1 As shown, in this embodiment, the support frame 1 is also provided with a pair of support positioning mechanisms 6. In use, the support positioning mechanisms 6 support both ends of the bearing plate 4 and position the bearing plate 4 after rotation.

[0038] In this embodiment, see Figure 6As shown, the support and positioning mechanism 6 includes a lifting cylinder 61. A support plate 62 is provided at the front end of the piston rod of the lifting cylinder 61. Two sets of third guide shafts 63 are provided at the lower end of the support plate 62, and two sets of positioning pins 64 are provided at the upper end of the support plate 62. The third guide shafts 63 and the positioning pins 64 are not limited to two sets; more sets can be provided. Positioning holes 43 adapted to the positioning pins 64 are provided on the bearing plate 4. During installation, the lifting cylinder 61 is fixed to the support frame 1. The three guide shafts 63 slidably pass through the support frame 1. In use, the lifting cylinder 61 drives the support plate 62 to move upward, so that the support plate 62 fits against the bearing plate 4, thereby supporting the bearing plate 4. The positioning holes 43 are inserted into the corresponding positioning holes 43 to position the bearing plate 4. It should be noted that when the bearing plate 4 needs to rotate, the lifting cylinder 61 drives the support plate 62 to move downward, and after the bearing plate 4 rotates, it returns to the support and positioning state.

[0039] Further, see Figure 1 As shown, in this embodiment, the support frame 1 is also equipped with a corresponding bracket 7 for a through-beam photoelectric sensor 8, which is located at the feeding position; the through-beam photoelectric sensor 8 controls the lifting mechanism 2 to lift one material thickness at a time.

[0040] The working principle of this utility model is as follows:

[0041] In use, materials are loaded into the two sets of storage mechanisms 5. When the material at the top of the storage mechanism 5 at the feeding position is removed, the second drive motor 24 starts, driving the lead screw 22 to rotate via the second synchronous belt pulley assembly 23. This drives the lifting plate 25 to move upward, thereby causing the lifting rod 26 to move upward, which in turn causes the lifting block 27 to move upward. The material is then lifted via the lifting movable plate 52. During the lifting process, when the photoelectric sensor 8 detects material, the second drive motor 24 stops. This process is repeated until all the material in the storage mechanism 5 at the feeding position is removed. 4. Start the lifting block 27 and drive it to descend and reset to the initial state. At the same time, the lifting cylinder 61 drives the support plate 62 to move down, releasing the support and positioning of the bearing plate 4. Then, the first drive motor 33 starts and drives the turntable of the turntable assembly 31 to rotate through the first synchronous belt pulley assembly 32, thereby driving the bearing plate 4 to rotate. This transfers the storage mechanism 5 located in the feeding position to the loading position, and the storage mechanism 5 located in the loading position to the feeding position. After the rotation is completed, the lifting cylinder 61 drives the support plate 62 to move up, restoring the support and positioning of the bearing plate 4. Then, the above feeding steps are repeated to continue feeding. This will not be described in detail here.

[0042] Among them, the storage mechanism 5, which completes the feeding from the feeding position and transfers to the loading position, is loaded with materials by the operator and awaits the next round of feeding.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
