Description

Technical Field

[0001] This utility model relates to the fields of mechanical engineering and automation technology, and in particular to an automatic feeding device for rivets. Background Technology

[0002] An automated rivet feeder is a device specifically designed to improve production efficiency, especially in large-scale manufacturing environments, by automating the supply of rivets to rivet guns. This device is typically fixed in a specific location on a workbench or production line to ensure convenient assembly operations for operators. It includes a storage bin for holding a large quantity of rivets and a feed rail that transports the rivets from the storage bin to the rivet gun.

[0003] However, a major limitation of this type of automatic feeding device is its fixed installation position, which cannot be adjusted in height or angle. Due to the lack of lifting capabilities, the device's height remains constant after installation, while certain specific requirements on the production line, such as handling workpieces of different sizes or types, may necessitate adjusting the feeding device's height. This fixed design limits the device's flexibility and adaptability, thus impacting overall work efficiency.

[0004] Therefore, it is necessary to provide an automatic feeding device for rivets to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic feeding device for rivets.

[0006] This utility model provides an automatic feeding device for rivets, comprising:

[0007] Support body;

[0008] A tabletop, which is disposed on the upper side of the main body of the support;

[0009] The main body of the device is mounted on the surface of the table.

[0010] The lifting assembly includes a threaded rod and two sets of lifting components. Both ends of the threaded rod are rotatably connected to the main body of the support. Each set of lifting components includes a threaded block, a first connecting frame, a movable arm, and a second connecting frame. The threaded block is threadedly connected to the circumferential surface of the threaded rod. The first connecting frame is fixedly connected to the surface of the threaded block. The movable arm is rotatably connected to the circumferential surface of the round rod portion of the first connecting frame. The round rod portion of the second connecting frame is rotatably connected to the movable arm, and the second connecting frame is fixedly connected to the surface of the table.

[0011] Preferably, the surface of the tabletop is fixedly connected with a plurality of sliding rods, each of which is slidably connected to the inner wall of each sleeve of the support body.

[0012] Preferably, the device further includes multiple sets of stabilizing components, each set of stabilizing components including a roller and a connecting rod, wherein the connecting rod is fixedly connected to the surface of the threaded block, and the roller is rotatably connected to the circumferential surface of the connecting rod.

[0013] Preferably, it also includes a rotating assembly, which includes a handle and a connecting plate. The connecting plate is fixedly connected to one end of the threaded rod, and there are two handles, both of which are slidably connected to the connecting plate.

[0014] Preferably, the threaded rod has a limit nut connected to its surface thread.

[0015] Preferably, the two sets of lifting components are symmetrical about the middle position of the threaded rod.

[0016] Compared with related technologies, the automatic feeding device for rivets provided by this utility model has the following advantages:

[0017] 1. This utility model effectively solves the problem of traditional automatic rivet feeding devices being unable to adapt to different working conditions due to their fixed installation height, by setting up a heightable table structure and a manual adjustment mechanism. Previously, once the equipment was installed, its feeding height could not be flexibly adjusted according to the operator's height, worktable size, or product type, leading to inconvenience and even affecting production efficiency. This device, however, rotates the handle to drive the threaded rod, causing the threaded blocks on both sides to move synchronously in opposite directions, thereby achieving smooth lifting and lowering of the table and the main body of the device. Operators can adjust to the optimal working height according to actual needs, significantly improving the applicability and operational comfort of the equipment, while also increasing feeding accuracy and assembly efficiency.

[0018] 2. The device adopts a stability design combining slide bars and rollers, combined with symmetrically distributed lifting components, to ensure smooth and wobbly table lifting process. At the same time, the quick locking and disengagement functions of the limit nut and handle enhance the reliability of equipment operation, simplify the operation process, and reduce maintenance costs. The overall structure combines practicality and safety. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 4 An automatic feeding device for rivets, comprising:

[0026] Support body 3;

[0027] Tabletop 2 is located on the upper side of the main body of the support 3;

[0028] Device body 1, which is mounted on the surface of table 2;

[0029] The lifting assembly includes a threaded rod 501 and two sets of lifting components. Both ends of the threaded rod 501 are rotatably connected to the bracket body 3. Each set of lifting components includes a threaded block 502, a first connecting frame 503, a movable arm 504, and a second connecting frame 505. The threaded block 502 is threadedly connected to the circumferential surface of the threaded rod 501. The first connecting frame 503 is fixedly connected to the surface of the threaded block 502. The movable arm 504 is rotatably connected to the circumferential surface of the round rod portion of the first connecting frame 503. The round rod portion of the second connecting frame 505 is rotatably connected to the movable arm 504, and the second connecting frame 505 is fixedly connected to the surface of the table 2.

[0030] In the specific implementation process, the rotating component drives the threaded rod 501 to rotate. The two threaded blocks 502, due to their opposite thread directions, will move in opposite directions on the threaded rod 501, driving the moving arms 504 on both sides to unfold to the sides, thereby pushing the table 2 to rise. Conversely, it will fall. After the table 2 rises and falls, it drives the main body 1 of the device installed on it to adjust its height synchronously. This allows the operator to flexibly adjust the height of the rivet gun on the main body 1 of the device according to their own needs or the position of the workpiece, thereby improving the comfort of use and work efficiency.

[0031] refer to Figures 1 to 4 As shown, multiple sliding rods 4 are fixedly connected to the surface of the tabletop 2, and each sliding rod 4 is slidably connected to the inner wall of each sleeve of the support body 3.

[0032] In the above embodiment, multiple sliding rods 4 on the surface of the tabletop 2 slide synchronously within the sleeve of the support body 3. When the tabletop 2 is raised or lowered, the sliding rods 4 move up and down along the inner wall of the sleeve to provide additional support and guidance for the tabletop 2, preventing tilting or swaying during the raising and lowering process and improving overall stability.

[0033] refer to Figures 1 to 4 As shown, it also includes multiple sets of stabilizing components. Each set of stabilizing components includes a roller 601 and a connecting rod 602. The connecting rod 602 is fixedly connected to the surface of the threaded block 502, and the roller 601 is rotatably connected to the circumferential surface of the connecting rod 602.

[0034] In the above embodiment, rollers 601 are installed on the connecting rods 602 on both sides of the threaded block 502. When the threaded block 502 moves along the threaded rod 501, the rollers 601 roll on the surface of the bracket body 3, reducing frictional resistance and dispersing the force. At the same time, the rolling trajectory of the rollers 601 is consistent with the moving direction of the threaded block 502, further enhancing the stability and reliability of the lifting process.

[0035] refer to Figures 1 to 4 As shown, it also includes a rotating assembly, which includes a handle 701 and a connecting plate 702. The connecting plate 702 is fixedly connected to one end of the threaded rod 501. There are two handles 701, and both handles 701 are slidably connected to the connecting plate 702.

[0036] In the above embodiment, when the handle 701 is rotated, the two handles 701 control the connecting plate 702 to rotate, ensuring that the applied force is evenly transmitted to the threaded rod 501. The connecting plate 702 is fixed to the end of the threaded rod 501. The rotation of the handle 701 drives the threaded rod 501 to rotate smoothly. The operation is labor-saving and precise. The handle 701 can be pulled out directly to prevent accidental collisions that may cause safety hazards during equipment operation or storage.

[0037] refer to Figures 1 to 4 As shown, the threaded rod 501 has a limit nut 8 connected to its surface thread.

[0038] In the above embodiment, tightening the limiting nut 8 to make it fit tightly against the bracket body 3, and physically locking it to prevent the threaded rod 501 from continuing to rotate, ensuring that the table 2 remains fixed after being adjusted to a suitable height, and preventing the height change caused by external force or vibration from affecting the accuracy of the rivet feeding.

[0039] refer to Figures 1 to 4 As shown, the two sets of lifting components are symmetrical about the middle position of the threaded rod 501.

[0040] In the above embodiment, the two sets of lifting components are symmetrically distributed at the middle position of the threaded rod 501, so that the threaded block 502 is subjected to balanced force on both sides when it moves on the threaded rod 501, avoiding the threaded rod 501 from deflecting or jamming due to excessive load on one side. The symmetrical design also ensures that the moving arm 504 moves synchronously, so that the table 2 remains horizontal during the lifting process, improving the operational stability and service life of the equipment.

[0041] The working principle of the automatic feeding device for rivets provided by this utility model is as follows:

[0042] By rotating the handle 701, the threaded rod 501 is rotated, causing the threaded blocks 502 on both sides to move in opposite directions and drive the moving arm 504 to unfold, thereby raising and lowering the table 2. This allows for flexible adjustment of the height of the main body 1 of the device, solving the problems of inconvenient operation and poor adaptability caused by the fixed installation height of traditional automatic feeding devices. Operators can adjust the height according to the position of the workpiece or their own needs, improving efficiency and comfort. After adjusting to the appropriate height, the limit nut 8 is tightened to fix the position of the threaded rod 501, and the rivets are installed into the storage bin inside the main body 1. The main body 1 of the device is then started, and the rivets are pushed into the rivet gun in sequence through the feeding track inside the main body 1, completing the automatic feeding process. The entire process is stable and efficient, and is suitable for various production scenarios.

[0043] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
