Description

Technical Field

[0001] This utility model relates to the field of gear assembly equipment technology, specifically to an automatic gear riveting machine. Background Technology

[0002] When assembling gear shafts and gear plates, an automatic riveting machine is used to rivet the gear shafts and gear plates together, which is one method of assembling gear shafts and gear plates.

[0003] Chinese patent document CN217776141U discloses an automatic gear riveting machine. The second groove in the gear receiving block extends through both sides of the gear receiving block along the conveying direction of the second conveying groove. When the first electric push rod pushes the gear into the second groove, the gear that has been riveted can be ejected. There is no need to set up an additional unloading drive mechanism, which further reduces the energy consumption of the device.

[0004] In the above scheme, the first electric push rod pushes the gear to push the riveted gear out of the second groove, and the positioning electric push rod moves the gear back to position. During use, a certain distance needs to be maintained between the extended end of the positioning electric push rod wheel and the gear receiving block, which makes the movement stroke of the positioning electric push rod longer, resulting in a larger size of the positioning electric push rod and increasing the overall size of the device. In addition, since the positioning electric push rod is above the discharge plate, the unloading of the riveted gear is affected. Utility Model Content

[0027] Example 1

[0028] like Figure 1-5 As shown, the present invention proposes an automatic gear riveting machine, which includes a mounting frame 1, a hydraulic cylinder 2, and a limit rod;

[0029] The hydraulic cylinder 2 is mounted on the top of the mounting bracket 1 and its extended end extends to the inside of the mounting bracket 1. The extended end of the hydraulic cylinder 2 is provided with a pressing block 3 for supporting the gear and riveting the gear to the shaft in the use state.

[0030] There are four limit rods, which are symmetrically installed on both sides of the inside of the lower pressure block 3. The ends of the limit rods are provided with adjustment components for rotating the limit rods in use and limiting the position of the limit rods relative to the gears.

[0031] In an optional embodiment, the lower pressure block 3 has a working cavity 4 in the middle that cooperates with the gear and shaft, and the two ends of the working cavity 4 are through. The bottom end of the working cavity 4 and the rear part of the lower pressure block 3 is provided with a notch 6. The width of the notch 6 is smaller than the diameter of the gear. It is used to transport the gear to the four limit rods through the working cavity 4 during use, and to move the gear outward to discharge material after riveting with the shaft through the notch 6.

[0032] In this embodiment, a working cavity 4 is provided in the middle of the lower pressure block 3, and the two ends of the working cavity 4 are through-holes. The gear is placed in the working cavity 4. At the same time, the adjustment component drives one end of the four limiting rods to move towards the side wall of the working cavity 4, and the limiting rods rotate in the working cavity 4, so that the other end of the limiting rods moves towards the middle of the working cavity 4. The four limiting rods restrict the gear in the middle of the working cavity 4 and are located directly above the shaft, so that the gear and shaft are accurately positioned. The hydraulic cylinder 2 drives the lower pressure block 3 to move down, so that the lower pressure block 3 passes through the notch 6 and rivets with the gear, so that the riveting accuracy of the gear and shaft is high. At the same time, the above arrangement is reversed so that the four limiting rods are placed in parallel, so that the gear and shaft are separated from the lower pressure block 3, thereby realizing the continuous riveting operation of the gear and shaft.

[0033] Example 2

[0034] like Figure 3-5 As shown, the automatic gear riveting machine proposed in this utility model differs from the first embodiment in that the limiting rod includes a stop rod 7, a single-headed bolt 8, and a nut 12.

[0035] The stop lever 7 is installed in the working chamber 4;

[0036] A single-headed bolt 8 passes through the lower pressure block 3 and the stop bar 7 and is installed on the lower pressure block 3;

[0037] Nut 12 is located at the top of the lower pressure block 3 and is connected to the single-headed bolt 8.

[0038] In an optional embodiment, the bottom end of the lower pressure block 3 is provided with a slot 11, and the bottom end of the single-headed bolt 8 is hexagonal. When the single-headed bolt 8 and the lower pressure block 3 are installed together, the bottom end of the single-headed bolt 8 is accommodated in the slot 11. This is used to restrict the rotation of the single-headed bolt 8 during use, so as to prevent the rotation of the stop bar 7 from causing the single-headed bolt 8 to rotate and thus causing the single-headed bolt 8 to fall off.

[0039] In this embodiment, the stop rod 7 is rotatably installed in the working cavity 4 by the cooperation of the single-headed bolt 8 and the nut 12, so that the rotation of the stop rod 7 drives the gear to adjust its position, and the cooperation of the four stop rods 7 limits the gear, ensuring that the gear is accurately positioned in the working cavity 4.

[0040] Example 3

[0041] like Figure 3 and Figure 5 As shown, the automatic gear riveting machine proposed in this utility model differs from the first embodiment in that the adjustment component includes an electric push rod 5 and a connecting shell 10.

[0042] The electric push rod 5 is installed on the side of the lower pressure block 3 and its extended end extends into the working chamber 4. During use, it extends and retracts by the forward and reverse rotation of the motor. This is the prior art and is only for illustration in the figure.

[0043] The connecting housing 10 is installed at the extended end of the electric push rod 5 and is slidably connected to the ends of the two stop rods 7.

[0044] In an optional embodiment, the side of the connecting shell 10 is provided with a sliding groove 13, the shape of the stop rod 7 is L-shaped, and the upper and lower end faces of one end of the stop rod 7 are provided with connecting posts 14. When the stop rod 7 and the connecting shell 10 are installed together, the connecting posts 14 are fitted and accommodated in the sliding groove 13. This is used to place multiple stop rods 7 in a parallel state through the connecting shell 10 during use, and to allow the stop rods 7 to rotate on the single-headed bolt 8 through the cooperation of the sliding groove 13 and the connecting posts 14.

[0045] In an optional embodiment, a tension spring 9 is provided on the other side of the stop rod 7. The two ends of the tension spring 9 are connected to the side wall of the stop rod 7 and the working cavity 4, respectively, to limit the position of the stop rod 7 during use and prevent the stop rod 7 from rotating downwards to the middle of the pressure block 3 due to the gap when it is placed in parallel.

[0046] In this embodiment, the electric push rod 5 drives the connecting shell 10 to move towards the side wall of the working cavity 4. This causes the connecting shell 10 to rotate the two stop rods 7 in the working cavity 4 through the cooperation of the sliding groove 13 and the connecting column 14. The end of the stop rod 7 moves towards the center of the working cavity 4, thereby driving the gear to adjust its position. The stop rod 7 also limits the position of the gear, ensuring that the gear is stable and without deviation during the riveting process, thus improving the riveting accuracy.

[0047] In this invention, a working cavity 4 is provided in the middle of the lower pressure block 3, and the two ends of the working cavity 4 are through-holes, so that the gear is placed in the working cavity 4. At the same time, two electric push rods 5 drive the connecting shell 10 to move synchronously towards the side wall of the working cavity 4. The connecting shell 10 drives the two stop rods 7 to rotate in the working cavity 4 through the cooperation of the sliding groove 13 and the connecting column 14. This causes the ends of the four stop rods 7 to move synchronously towards the middle of the working cavity 4, thereby adjusting the position of the gear by the stop rods 7. The cooperation of the four stop rods 7 also limits the gear, ensuring that the gear is stable and without deviation during the riveting process, thus improving the riveting accuracy and efficiency. At the same time, the hydraulic cylinder 2 drives the lower pressure block 3 to move down, so that the lower pressure block 3 passes through the notch 6 and rivets with the gear. The electric push rod 5 drives the connecting shell 10 to move towards the middle of the connecting shell 10. At the same time, the tension spring 9 generates tension, so that the four stop rods 7 are placed in parallel, so that the gear to be riveted is pushed out of the working cavity 4 after riveting. This achieves continuous riveting of the gear and the shaft.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
