Technical Field

[0001] This utility model relates to the technical field of fastening nut processing equipment, specifically to an automatic loading and unloading device for a fastening nut punch press. Background Technology

[0002] A fastener nut is a common fastener, primarily used with bolts, studs, or machine screws to achieve a secure connection between two parts. Nuts are typically flat hexagonal prisms, but can also be flat square or flat cylindrical, with an internal threaded hole that matches the external thread of the bolt. Key characteristics of fastener nuts include ease of installation, integral design, convenient disassembly, and reusability. A fastener nut punch press is a type of stamping press used to deform fastener nuts to achieve the desired shape.

[0003] However, existing fastening nut punching machines require multiple power devices to drive the fastening nuts for loading, unloading, and moving, resulting in a complex overall structure and high production costs. Utility Model Content

[0034] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0035] Example 1

[0036] like Figures 1-2 As shown, this embodiment proposes:

[0037] An automatic loading and unloading device for a fastening nut punch press includes a worktable 1, a punching mechanism 2 fixed to the rear side of the top wall of the worktable 1, and further includes:

[0038] Limiting ring 3 is fixed on the top wall of workbench 1. A feeding plate 4 is rotatably installed inside the limiting ring 3. A storage trough 5 is symmetrically opened on the side wall of the feeding plate 4.

[0039] The feeding component 6 is installed on the top wall of the workbench 1, and the side wall of the limiting ring 3 has a feeding port corresponding to the position of the feeding component 6.

[0040] Collection box 8 is mounted on the front wall of workbench 1 via support frame 9. An inclined feeding groove 7 is provided on the front side of workbench 1 corresponding to the position of collection box 8, and a feeding port is provided on the side wall of limiting ring 3 corresponding to the position of feeding groove 7.

[0041] The Geneva mechanism 10 is installed inside the workbench 1. The workbench 1 is equipped with a motor 11 that drives the Geneva mechanism 10 to work. The Geneva mechanism 10 is used to drive the feeding disc 4 to rotate. The Geneva mechanism 10 drives the feeding assembly 6 to work through the transmission mechanism 13.

[0042] There are two support frames 9, and the support frames 9 are L-shaped and are symmetrically arranged on the front wall of the worktable 1.

[0043] In this embodiment, the limiting ring 3 is used to cooperate with the storage trough 5 on the feeding tray 4 to transmit the fastening nut. The feeding tray 4 is driven to rotate intermittently by the grooved wheel mechanism 10. Each time the feeding tray 4 stops moving, there is a storage trough 5 located below the stamping mechanism 2. The stamping mechanism 2 can punch holes in the fastening nut. When the stamped fastening nut moves to the position of the unloading trough 7, it can fall into the collection box 8 for collection. At the same time, the grooved wheel mechanism 10 can drive the feeding component 6 to work through the transmission mechanism 13 to continuously feed the material into the storage trough 5. The overall linkage is strong and the degree of automation is high.

[0044] Example 2

[0045] like Figures 3-4 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes:

[0046] The feeding assembly 6 includes a feeding pipe 61, and a limit pipe 62 is fixed at the bottom end of the feeding pipe 61;

[0047] The limiting tube 62 is fixed to the top wall of the workbench 1, and a push block 63 is slidably installed inside the limiting tube 62;

[0048] A connecting rod 64 is fixed to the side wall of the push block 63, and a limit frame 65 is fixed to the other end of the connecting rod 64.

[0049] A limiting post 66 is slidably installed inside the limiting frame 65. A turntable 67 is fixed at the bottom of the limiting post 66 and is rotatably installed on the top wall of the workbench 1.

[0050] The workbench 1 has an installation slot 12, and the grooved wheel mechanism 10 is installed in the installation slot 12.

[0051] The Geneva mechanism 10 includes a Geneva wheel 101, which is rotatably mounted in the mounting groove 12 via a mounting shaft. The mounting shaft of the Geneva wheel 101 passes through the top wall of the workbench 1 via a bearing and is fixedly connected to the center of the bottom wall of the feeding tray 4. A matching active dial 102 is installed on one side of the Geneva wheel 101.

[0052] The active dial 102 is rotatably mounted in the mounting groove 12 via a rotating shaft. The power shaft of the motor 11 is fixed at the axial position of the bottom wall of the active dial 102. A cylindrical pin 103 that cooperates with the grooved wheel 101 is fixed on the outer edge of the top wall of the active dial 102.

[0053] The transmission mechanism 13 includes a drive gear 131, which is fixed on the rotating shaft of the drive dial 102 and is meshed with a transmission gear 132.

[0054] The transmission gear 132 is rotatably mounted on the bottom wall of the mounting groove 12, and the transmission gear 132 is meshed with the driven gear 133.

[0055] A rotating shaft 134 is fixed at the top axis of the driven gear 133;

[0056] The top of the rotating shaft 134 passes through the top wall of the worktable 1 via a bearing and is fixedly connected to the bottom axis of the turntable 67.

[0057] The driving gear 131 and the driven gear 133 are the same size.

[0058] The number of grooves in the groove wheel 101 is the same as the number of storage troughs 5, and their positions correspond to each other.

[0059] In this embodiment, the motor 11 drives the Geneva mechanism 10 to work. The Geneva mechanism 10 drives the feeding disc 4 to move intermittently, while simultaneously driving the feeding assembly 6 through the transmission mechanism 13, continuously replenishing the storage trough 5 with fastening nuts to be processed. When the Geneva mechanism 10 is working, the motor 11 drives the active dial 102 to rotate. The active dial 102 drives the Geneva wheel 101 to rotate intermittently through the cylindrical pin 103. The Geneva wheel 101 drives the feeding disc 4 to rotate synchronously. During the rotation of the Geneva wheel 101 by the active dial 102, the active dial 102 drives the rotating shaft 134 to rotate through the active gear 131, transmission gear 132, and driven gear 133. The rotating shaft 134 drives the turntable 67 to rotate. At this time, the turntable 67 drives the push block 63 through the limiting post 66, limiting frame 65, and connecting rod 64. Away from the feeding disc 4, while the active dial 102 rotates without driving the grooved wheel 101 to rotate, the active dial 102 drives the rotating shaft 134 to rotate through the active gear 131, the transmission gear 132 and the driven gear 133. The rotating shaft 134 drives the turntable 67 to rotate. At this time, the turntable 67 drives the push block 63 to move towards the feeding disc 4 through the limiting post 66, the limiting frame 65 and the connecting rod 64. At this time, the fastening nut in the feeding pipe 61 is pushed into the storage tank 5. The above operation is continuously repeated to complete the continuous feeding and unloading of the fastening nut.

[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
