Abstract
Description
Technical Field
[0001] This utility model relates to the field of workpiece feeding technology, specifically a feeding mechanism for processing ring-shaped workpieces. Background Technology
[0002] Ring-shaped workpieces refer to mechanical parts with a ring shape, which are widely used in many industrial fields, especially for the housing of automotive airbag ignition generators.
[0003] In the prior art, a Chinese utility model patent discloses a ring-shaped workpiece feeding device (publication number: CN208345269U). Specifically, it discloses that in use, the ring-shaped workpiece is placed on the mounting bracket, and the feeding trolley is fixed directly below the lifting device using a trolley fixing device. The conveying device is fixedly installed on the lifting device. The lifting device drives the conveying device to descend, and the conveying device pushes the ring-shaped workpiece to move gradually along the mounting bracket. This ensures that the robot arm can always grasp the ring-shaped workpiece located at the top of the mounting bracket. When the robot arm grasps, it can pass through the inner hole of the ring-shaped workpiece for conveying, which facilitates the robot arm passing through the inner hole of the ring-shaped workpiece.
[0004] However, when using this existing technology, the ring-shaped workpiece may wobble on the mounting bracket. Once the ring-shaped workpiece wobbles, the workpieces will collide with each other, causing damage to the workpiece.
[0005] Therefore, this utility model provides a feeding mechanism for processing ring-shaped workpieces to solve the above problems. Utility Model Content
[0006] This utility model provides a feeding mechanism for processing ring-shaped workpieces, aiming to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A feeding mechanism for processing annular workpieces includes a base platform. A longitudinal plate is fixedly installed on the top surface of the base platform. Two sets of transverse plates are fixedly installed on the sides of the longitudinal plate. A connecting block is rotatably installed in each set of transverse plates. A carrying rod is fixedly installed on the side of the connecting block. The carrying rod has a hollow cavity. A symmetrical slot is opened on the outer surface of the carrying rod. An insert plate is movably inserted into the slot. An arc-shaped plate adapted to the surface of the carrying rod is fixedly installed on the top surface of the insert plate. A pressing component is provided at the end of the carrying rod away from the connecting block. The pressing component is used to adjust the position of the insert plate. A driving component is provided on the two sets of transverse plates. The driving component is used to adjust the angle of the carrying rod.
[0009] As a further optimization, the insert plate is inclined on the side near the extrusion assembly.
[0010] As a further optimization, the extrusion assembly includes a bolt threaded into one end of the load rod, and an extrusion block is rotatably mounted on one end of the bolt inside the load rod via a bearing. Both sides of the extrusion block are inclined, and both sides of the extrusion block are tightly attached to the inclined surface of the insert plate. A limit assembly is provided between the insert plate and the extrusion block.
[0011] As a further optimization, the limiting component includes a groove formed on the inclined surface of the insert plate, and a slider fixedly installed on the side of the extrusion block is slidably inserted into the groove.
[0012] As a further optimization, limit grooves are provided on both sides of the inner wall of the slide, and limit rods that are slidably inserted and fixedly installed on both sides of the slider are installed in the limit grooves.
[0013] As a further optimization, the drive assembly includes a rotating rod disposed between two sets of horizontal plates.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1: This utility model provides a feeding mechanism for processing ring-shaped workpieces, such as... Figures 1 to 5 As shown, the feeding mechanism includes a base platform 1, a longitudinal plate 2 fixedly installed on the top surface of the base platform 1, two sets of transverse plates 3 fixedly installed on the sides of the longitudinal plate 2, a connecting block 4 rotatably installed in each set of transverse plates 3, a carrying rod 5 fixedly installed on the side of the connecting block 4, the carrying rod 5 having a hollow interior, symmetrical slots 12 opened on the outer surface of the carrying rod 5, insert plates 13 movably inserted into the slots 12, an arc-shaped plate 6 adapted to the surface of the carrying rod 5 fixedly installed on the top surface of the insert plate 13, a pressing component provided at the end of the carrying rod 5 away from the connecting block 4, the pressing component being used to adjust the position of the insert plate 13, and a driving component provided on the two sets of transverse plates 3, the driving component being used to adjust the angle of the carrying rod 5.
[0026] In Example 2, based on Example 1, the insert plate 13 is inclined on the side near the extrusion assembly.
[0027] In Example 3, based on Example 2, the extrusion assembly includes a bolt 14 threaded into one end of the carrying rod 5. The bolt 14 is located inside the carrying rod 5 and an extrusion block 15 is rotatably mounted on one end via a bearing. Both sides of the extrusion block 15 are inclined and are tightly attached to the inclined surface of the insert plate 13. A limit assembly is provided between the insert plate 13 and the extrusion block 15.
[0028] In Example 4, based on Example 3, the limiting component includes a groove 16 formed on the inclined surface of the insert plate 13. A slider 18 fixedly installed on the side of the extrusion block 15 is slidably inserted into the groove 16. The arrangement of the groove 16 and the slider 18 can prevent the extrusion block 15 from being misaligned.
[0029] In Example 5, based on Example 1, limiting grooves 17 are provided on both sides of the inner wall of the slide groove 16. Limiting rods 19 are slidably inserted and fixedly installed on both sides of the slider 18 in the limiting grooves 17. The setting of the limiting grooves 17 and the limiting rods 19 can prevent the slider 18 from detaching from the slide groove 16, so that the insert plate 13 and the extrusion block 15 are always in contact.
[0030] In Example 6, based on Example 1, the drive assembly includes a rotating rod 7 disposed between two sets of horizontal plates 3. The two ends of the rotating rod 7 pass through the horizontal plates 3 and are fixedly inserted into the connecting block 4. A driven bevel gear 11 is fixedly sleeved in the middle of the rotating rod 7. A driving bevel gear 10 is meshed on the surface of the driven bevel gear 11. A brake motor 9 is fixedly inserted into the side of the driving bevel gear 10 and disposed on the side of the longitudinal plate 2. The output end of the brake motor 9 is fixedly connected to the driving bevel gear 10.
[0031] In Example 7, based on Example 1, a limiting ring 8 is fixedly sleeved on the outer peripheral surface of the carrying rod 5 near the connecting block 4. The limiting ring 8 can prevent the annular workpiece on the carrying rod 5 from contacting the connecting block 4.
[0032] When using this invention, first place the base platform 1 within the range of motion of the robotic arm. Then, sequentially attach the annular workpiece to the surfaces of the two carrying rods 5. The angle of the two carrying rods 5 can then be adjusted via the brake motor 9, making it easier for the robotic arm to pick up the annular workpiece from the carrying rods 5. Specifically, when the brake motor 9 is activated, its output drives the driving bevel gear 10 to rotate, which in turn drives the driven bevel gear 11 to rotate. The driven bevel gear 11 then drives the rotating rod 7 to rotate, causing the two connecting blocks 4 to rotate, ultimately adjusting the angle of the carrying rods 5. For the purpose of this device, during idle periods, to prevent the annular workpiece from wobbling on the carrying rod 5, the operator can tighten bolt 14. Bolt 14 will push the pressing block 15 to move. The movement of the pressing block 15 will cause the two insert plates 13 to move outward. The outward movement of the insert plates 13 will allow the arc plate 6 to press against the inner wall of the annular workpiece, thereby pressing and fixing the annular workpiece on the carrying rod 5. The pressing and fixing by the arc plate 6 can fix annular workpieces of various sizes, preventing the annular workpieces on the carrying rod 5 from colliding with each other after the device is impacted.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
