Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically to an automatic feeding mechanism for irregularly shaped riveted parts in a riveting machine. Background Technology

[0002] A riveting machine is a mechanical device used to join materials such as metal and plastic using rivets or riveted parts. Its working principle is to use pressure or impact to deform the rivet, forming a permanent fastened joint. It is widely used in industries such as automotive, aerospace, electronics, and construction. Riveting machines can be divided into manual, pneumatic, hydraulic, and CNC types, and are characterized by high connection strength, good shock resistance, and strong sealing.

[0003] However, existing riveting machines typically only have one fixed station for loading materials. Operators or mechanical devices must first remove the stamped riveted parts from the station before placing the blank to be stamped in, before proceeding to the next process. This results in intermittent pauses in the processing, severely impacting production efficiency and making it difficult to meet the demands of automation and mass production. To address these issues, the inventors have proposed an automatic loading mechanism for irregularly shaped riveted parts in riveting machines. Utility Model Content

[0004] In order to solve the problem of low continuous feeding efficiency of irregular riveting parts for riveting machines, the purpose of this utility model is to provide an automatic feeding mechanism for irregular riveting parts for riveting machines.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: an automatic feeding mechanism for irregularly shaped riveting parts for a riveting machine, comprising a base plate, a limiting platform fixedly installed at the top of the base plate, a through groove in the middle of the limiting platform, a turntable rotatably connected to the top of the base plate above the limiting platform, the rotating shaft of the turntable movably passing through the through groove, four centrally symmetrically distributed work station slots at the top of the turntable, a mounting frame fixedly connected to the top of the base plate near the turntable, one side of the top of the mounting frame rotatably connected to the rotating shaft of the turntable, a feed pipe communicating with the interior of the mounting frame fixedly connected to the top of the mounting frame, riveting parts bodies arranged inside the feed pipe, and a riveting machine body disposed on the top of the base plate near the limiting platform.

[0006] Preferably, a rotating wheel is fixedly connected to the outer side of the turntable shaft. The side of the rotating wheel has four arc-shaped grooves that are centrally symmetrically distributed. A shift groove is formed between two adjacent arc-shaped grooves. A stepper motor is fixedly installed on the top of the base plate near the rotating wheel. A grooved wheel is fixedly connected to the drive end of the stepper motor. A shift rod is fixedly connected to one side of the grooved wheel. A shift pin is fixedly connected to the top of the shift rod away from the grooved wheel. The shift pin is movably engaged in the shift groove.

[0007] Preferably, a support column is fixedly connected to the top of the base plate and below the side of the limiting platform near the riveting machine body. The top of the support column is in contact with the bottom surface of the limiting platform, and the central axis of the support column is in the same straight line as the central axis of the stamping head of the riveting machine body.

[0008] Preferably, a limiting frame is fixedly connected to the bottom of the turntable and below the work station slot. The ground of the limiting frame is in contact with the top of the groove wheel. A discharge slot is provided on the side of the limiting platform away from the feed pipe. The area of ​​the discharge slot is larger than the area of ​​the inner ring of the limiting frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] By continuously placing the riveted parts into the feed tube, a stepper motor drives the groove wheel, lever, and pin to rotate. When the work station slot rotates to directly below the feed tube, the riveted parts fall into the limiting frame under gravity. As the through slot continues to rotate, the riveted parts rotate to directly below the punch head of the riveting machine body. The riveted parts are then punched. When the turntable rotates the limiting frame containing the processed riveted parts to above the unloading slot, the riveted parts automatically fall out of the limiting frame under gravity for collection, thus achieving automatic unloading of the riveted parts and further improving the continuous processing efficiency of the riveted parts.

[0017] 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.

[0018] Example: Figure 1-4 As shown, this utility model provides an automatic feeding mechanism for irregularly shaped riveting parts for a riveting machine, including a base plate 1, a limiting platform 2 fixedly installed at the top of the base plate 1, a through groove 3 opened in the middle of the limiting platform 2, a turntable 4 rotatably connected to the top of the base plate 1 and above the limiting platform 2, the rotating shaft of the turntable 4 movably passing through the through groove 3, four station slots 5 centrally symmetrically distributed at the top of the turntable 4, a mounting frame 6 fixedly connected to the top of the base plate 1 near the turntable 4, one side of the top of the mounting frame 6 rotatably connected to the rotating shaft of the turntable 4, a feed pipe 7 fixedly connected to the top of the mounting frame 6 communicating with the inside of the mounting frame 6, the riveting part body 8 arranged inside the feed pipe 7, and a riveting machine body 9 provided at the top of the base plate 1 near the limiting platform 2.

[0019] A rotating wheel 10 is fixedly connected to the outer side of the rotating shaft of the turntable 4. Four arc-shaped grooves 11 are centrally symmetrically distributed on the side of the rotating wheel 10. A shift groove 12 is provided between two adjacent arc-shaped grooves 11. A stepper motor 13 is fixedly installed on the top of the base plate 1 near the rotating wheel 10. A grooved wheel 14 is fixedly connected to the drive end of the stepper motor 13. A shift rod 15 is fixedly connected to one side of the grooved wheel 14. A shift pin 16 is fixedly connected to the top of the shift rod 15 away from the grooved wheel 14. The shift pin 16 is movably engaged in the shift groove 12.

[0020] By adopting the above technical solution, the stepper motor 13 drives the grooved wheel 14, the lever 15 and the pin 16 to rotate. When the pin 16 rotates into the inside of the groove 12, it drives the rotating wheel 10 to rotate, thereby driving the turntable 4 to rotate. When the grooved wheel 14 rotates to the point where the convex surface of the grooved wheel 14 contacts the inner wall of the arc groove 11, the rotating wheel 10 is stationary as the grooved wheel 14 rotates. At this time, the stamping operation of the riveting body 8 is performed during the intermittent time. Since the rotating wheel 10 has four centrally symmetrically distributed grooves 12, the turntable 4 rotates 45 degrees when the grooved wheel 14 rotates one revolution, thereby realizing the continuous switching of the work station grooves 5 on the turntable 4.

[0021] A support column 17 is fixedly connected to the top of the base plate 1 and below the side of the limiting platform 2 near the riveting machine body 9. The top of the support column 17 is in contact with the bottom surface of the limiting platform 2, and the central axis of the support column 17 is in the same straight line as the central axis of the punch head of the riveting machine body 9.

[0022] By adopting the above technical solution and setting the support column 17, when the punching head of the riveting machine body 9 acts on the riveting part body 8, the support column 17 provides stable support for the limiting platform 2, thereby improving the stability of the equipment.

[0023] The bottom of the turntable 4 and below the work station slot 5 are fixedly connected to a limiting frame 19, and the ground of the limiting frame 19 is in contact with the top of the groove wheel 14.

[0024] By adopting the above technical solution, and by setting the limiting frame 19, when the riveting body 8 falls into the inside of the limiting frame 19, the limiting frame 19 is used to limit the riveting body 8 and prevent the position of the riveting body 8 from shifting.

[0025] A discharge trough 18 is provided on the side of the limiting platform 2 away from the feed pipe 7, and the area of ​​the discharge trough 18 is larger than the area of ​​the inner ring of the limiting frame 19.

[0026] By adopting the above technical solution and by setting up the feeding trough 18, when the turntable 4 drives the limiting frame 19, which contains the processed riveting body 8, to rotate above the feeding trough 18, the riveting part will automatically fall out from the inside of the limiting frame 19 for collection by the gravity of the riveting part.

[0027] Working principle: When stamping the riveting body 8, the riveting body 8 is continuously placed inside the feed tube 7. The stepper motor 13 drives the groove wheel 14, the lever 15 and the pin 16 to rotate. When the pin 16 rotates to the inside of the groove 12, it drives the rotating wheel 10 to rotate, thereby driving the turntable 4 to rotate 45 degrees. When the station slot 5 rotates to the bottom of the feed tube 7, the riveting body 8 falls into the inside of the limit frame 19 under the action of gravity. As the through slot 3 continues to rotate, the riveting body 8 rotates to the bottom of the stamping head of the riveting machine body 9. The stamping operation of the riveting body 8 is carried out during the intermittent time.

[0028] As the through groove 3 continues to rotate, when the turntable 4 drives the limiting frame 19, which contains the processed riveted part body 8, to rotate above the unloading groove 18, the riveted part automatically falls out from the inside of the limiting frame 19 for collection by gravity, thus realizing the automatic unloading operation of the riveted part body 8. This operation is repeated to realize the automatic continuous feeding operation of the riveted part body 8, further improving the processing efficiency of the riveted part body 8.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
