[0006] Therefore, the purpose of this utility model is to provide an automatic riveting device for micro motors, which solves the problem that existing micro motor riveting devices require workers to fix them first before riveting them, and when batch riveting of micro motors is required, each micro motor needs to be fixed and disassembled one by one, thus reducing the efficiency of micro motor riveting.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automatic riveting device for a micro motor includes a base. A first rotating rod is rotatably connected to the upper surface of the base. A circular plate is fixedly connected to the upper end of the first rotating rod. The upper surface of the circular plate has multiple placement holes, and a micro motor body is placed inside each placement hole. A driving mechanism is provided on the upper surface of the base. A transmission mechanism is provided between the driving mechanism and the first rotating rod. The driving mechanism drives the first rotating rod to rotate through the transmission mechanism. An annular block is fixedly connected to the upper surface of the base and is located below the circular plate. An L-shaped plate is fixedly connected to the upper surface of the base. A cylinder is fixedly connected to the lower surface of the L-shaped plate. A riveting pressure block is fixedly connected to the lower surface of the cylinder. The riveting pressure block matches the micro motor body.

[0009] Preferably, the drive mechanism includes a motor and a drive gear, the motor is fixedly connected to the upper surface of the base, and the drive gear is fixedly sleeved on the output end of the motor.

[0010] Preferably, the transmission mechanism includes a driven gear, a second rotating rod, a grooved wheel, and a dial. The second rotating rod is rotatably connected to the upper surface of the base. The driven gear is fixedly sleeved on the rod wall of the second rotating rod and meshes with the driving gear. The grooved wheel is fixedly sleeved on the rod wall of the first rotating rod. The dial is fixedly connected to the rod wall at one end of the second rotating rod and matches the grooved wheel.

[0011] Preferably, a discharge trough is provided on the outer side of the annular block, and the lower surface of the discharge trough is inclined.

[0012] Preferably, the inner wall of the annular block is provided with a placement groove, which is matched with the motor.

[0013] Preferably, the driven gear is larger than the driving gear.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model involves placing the assembled micro motor body inside the corresponding placement hole, and then rotating the circular plate to rotate it one by one to the bottom of the riveting block. Then, the cylinder is activated to rivet the outer shell of the micro motor body and the base together, thereby improving the riveting efficiency.

[0016] 2. In this utility model, by starting the motor, the driving gear rotates, which in turn drives the driven gear to rotate. Because the size of the driven gear is smaller than that of the driving gear, the speed of the driven gear is much smaller than that of the driving gear. Then the driven gear can drive the second rotating rod to rotate slowly, and then the dial can drive the grooved wheel to rotate intermittently, so that the micro motor body can move intermittently to the bottom of the riveting pressure block.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a micro motor automatic riveting device.

[0026] This utility model provides, for example Figure 1-4The illustrated automatic riveting device for a micro motor includes a base 1. A first rotating rod 2 is rotatably connected to the upper surface of the base 1. A circular plate 3 is fixedly connected to the upper end of the first rotating rod 2. The upper surface of the circular plate 3 has multiple placement holes, and a micro motor body 4 is placed inside each placement hole. A driving mechanism is provided on the upper surface of the base 1, and a transmission mechanism is provided between the driving mechanism and the first rotating rod 2. The driving mechanism drives the first rotating rod 2 to rotate through the transmission mechanism. An annular block 5 is fixedly connected to the upper surface of the base 1, and the annular block 5 is located below the circular plate 3. An L-shaped plate 6 is fixedly connected to the upper surface of the base 1, and a cylinder 7 is fixedly connected to the lower surface of the L-shaped plate 6. A riveting pressure block 8 is fixedly connected to the lower surface of the cylinder 7, and the riveting pressure block 8 matches the micro motor body 4.

[0027] The assembled micro motor body 4 is placed inside the corresponding placement hole. Then, by rotating the circular plate 3, it can be rotated one by one to the bottom of the riveting block 8. Then, the cylinder 7 is activated to rivet the outer shell of the micro motor body 4 and the base together, thereby improving the riveting efficiency.

[0028] In order for the circular plate 3 to rotate intermittently, such as Figure 1-3 As shown, the driving mechanism includes a motor 9 and a drive gear 10. The motor 9 is fixedly connected to the upper surface of the base 1, and the drive gear 10 is fixedly sleeved on the output end of the motor 9. The transmission mechanism includes a driven gear 11, a second rotating rod 12, a grooved wheel 13, and a dial 14. The second rotating rod 12 is rotatably connected to the upper surface of the base 1. The driven gear 11 is fixedly sleeved on the rod wall of the second rotating rod 12 and meshes with the drive gear 10. The grooved wheel 13 is fixedly sleeved on the rod wall of the first rotating rod 2. The dial 14 is fixedly connected to the rod wall at one end of the second rotating rod 12 and matches the grooved wheel 13. The size of the driven gear 11 is larger than the size of the drive gear 10. The inner wall of the annular block 5 is provided with a placement groove, which matches the motor 9.

[0029] Start the motor 9 to make the drive gear 10 rotate, which in turn drives the driven gear 11 to rotate. Because the size of the driven gear 11 is smaller than that of the drive gear 10, the speed of the driven gear 11 is much smaller than that of the drive gear 10. Then the driven gear 11 can drive the second rotating rod 12 to rotate slowly. Then the dial 14 can drive the grooved wheel 13 to rotate intermittently, so that the micro motor body 4 can move intermittently to the bottom of the riveting pressure block 8.

[0030] To facilitate the removal of motor 9, such as Figure 1-2 As shown, a discharge trough is provided on the outer side of the annular block 5, and the lower surface of the discharge trough is inclined.

[0031] Each discharge chute allows the riveted motor to fall out, making it easier to collect the motor 9.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
