Description

Technical Field

[0001] This application relates to the field of nut feeding, and more specifically to a bidirectional feeding device based on nut materials. Background Technology

[0002] In the fastener manufacturing industry, nuts are common fastening components with huge market demand, and their processing efficiency and automation level directly affect the economic benefits of manufacturing enterprises. Currently, in the CNC turning process of nuts, manual feeding or semi-automatic feeding devices are usually used to feed materials to CNC lathes. Traditional nut feeding methods have the following main technical problems: First, most existing feeding devices can only feed materials to a single CNC lathe. When multiple CNC lathes are arranged in parallel in the workshop, each machine needs to be equipped with an independent feeding device, which not only increases equipment purchase and floor space costs, but also hinders the improvement of overall workshop processing efficiency and the intensive layout of the production line. Second, the material bins or trays of existing feeding devices are usually fixed structures. After a batch of materials is processed, the machine needs to be stopped for manual replenishment or tray replacement, which shortens the effective processing time of the equipment and affects the continuity of production cycle. Therefore, there is a need for a bidirectional feeding device for nuts that can simultaneously feed materials to two CNC lathes and achieve non-stop replenishment switching. Summary of the Invention

[0003] The main purpose of this application is to provide a bidirectional feeding device based on nut materials, wherein the bidirectional feeding device based on nut materials can effectively utilize its own structural configuration to achieve the advantages of simultaneously feeding multiple CNC lathes and switching between feeding and replenishing materials without stopping the machine.

[0025] It should be noted that the worktable 10 also has a through-slot structure 101, and the first drive assembly 22 has a first telescopic rod. The end of the first telescopic rod away from the first drive assembly 22 passes through the through-slot structure 101 and is placed at the bottom of the worktable 10.

[0026] Specifically, the lifting assembly 20 further includes an insertion plate 23, which is fixed to the end of the first telescopic rod and is perpendicular to the first telescopic rod.

[0027] Additionally, it should be noted that the bidirectional feeding device based on nut material further includes a rotating platform 30, which is located at the bottom of the workbench 10 and close to the ground. The bidirectional feeding device also includes multiple discharging devices 40, which are evenly distributed on the rotating platform 30. Those skilled in the art should understand that a second driving assembly (not shown in the figure) is also provided at the bottom of the rotating platform 30. This second driving assembly has a rotating shaft that is configured to drive the rotating platform 30 to rotate, allowing the positions of the multiple discharging devices 40 on the rotating platform 30 to continuously change. During rotation, the insertion plate 23 is configured to cooperate with one of the discharging devices 40, and the first driving assembly 22 lifts the corresponding discharging device 40 to the through-slot structure 101 or the upper side of the workbench 10 for subsequent material handling.

[0028] Specifically, the rotating platform 30 has a plurality of evenly distributed mounting notches 301, which are all located on the periphery of the rotating platform 30. Each mounting notch 301 has a positioning groove 302, with two positioning grooves 302 located on either side of the mounting notch 301 and communicating with it.

It is worth mentioning that a retaining plate (not shown in the figure) can be provided on the side of the base plate 411 away from the top plate 412. When the base plate 411 is placed into the mounting notch 301, the retaining plate contacts the sensing probe and the corresponding sensing device 100 to confirm that the tooling plate 41 is in place. Then, the rotating table 30 rotates by a predetermined angle so that the adjacent tooling plate 41 cooperates with the insertion plate 23. Specifically, the insertion plate 23 is configured to be placed between the top plate 412 and the base plate 411. When the insertion part moves upward a predetermined distance, the insertion plate 23 can lift the tooling plate 41 to a predetermined height to disengage from the corresponding mounting notch 301 and place it in the through groove structure 101. It should also be noted that the top plate 412 has an assembly groove 41201 on the side facing the bottom plate 411 that mates with the insertion plate 23. During the process of lifting the insertion plate 23, the top plate 412 is first placed in the assembly groove 41201, and then a force is applied to the tooling plate 41 to lift the corresponding worktable 10.

[0031] It should be noted that each of the feeding devices 40 includes a feeding rack 42, which is fixed to the top of the tooling plate 41, that is, the feeding rack 42 is fixed to the side of the top plate 412 away from the bottom plate 411.

The guide block 43 can be fixed to the tooling plate 41 by screws. In addition, the guide block 43 also has an opening and a guide groove 4301. The opening is connected to the guide groove 4301. The external nut placed in the placement cavity 4201 will fall into the guide groove 4301 along the strip-shaped stop 42011. At the same time, the side wall of the guide groove 4301 limits the movement position of the external nut. Specifically, each of the feeding devices 40 includes a pushing component 44, which is mounted on the tooling plate 41 and close to the opening of the guide block 43. The pushing component 44 includes a third driving component and a push block 441. The third driving component is fixed on the tooling plate 41 and has a second telescopic rod. The end of the second telescopic rod is fixedly engaged with the push block 441 and is pushed open within the guide groove 4301.
