[0015] Example 1, as Figures 1 to 4As shown, this utility model proposes a riveting device for a micro motor end cap, including a frame 1, a riveting mechanism 3, a motor housing placement mechanism 2, an adjustment component, multiple sets of abutment seats 6, and multiple sets of riveting joints 7. A lifting component 101 is installed at the top of the frame 1. The lifting component 101 is a hydraulic rod equipped with a displacement sensor, which can monitor the displacement distance of the riveting mechanism 3 in real time, ensuring precise and controllable riveting stroke. The riveting mechanism 3 is detachably connected to the output end of the lifting component 101. The riveting mechanism 3 is driven by the lifting component 101 to move and adjust along the height direction of the frame 1. The motor housing placement mechanism 2 is detachably mounted on the frame by bolts. Located above and below the riveting mechanism 3, the motor housing placement mechanism 2 and the riveting mechanism 3 both include a fixed base 4 and an adjustment component. The motor housing placement mechanism 2 and the riveting mechanism 3 have different sizes to accommodate different functional requirements. A groove 401 is provided on the fixed base 4, and the adjustment component is set in the groove 401, including a rotating seat 5, a guide groove 502, and a slide bar B504. The rotating seat 5 is driven to rotate and adjust along the groove 401 by a driving component installed inside the fixed base 4. The driving component consists of a servo motor, a gear transmission component, a rotating shaft and reducer, and an encoder. The servo motor drives the rotating shaft to rotate through the gear transmission component. The encoder precisely controls the rotation angle to ensure adjustment accuracy. A clearance groove 501 is provided in the middle of the rotating seat 5 to accommodate the motor's rotor shaft. The diameter of the clearance groove 501 is larger than the rotor shaft diameter, facilitating the placement of rotor shafts of different sizes. Multiple sets of guide grooves 502 are evenly distributed on the rotating seat 5, and slide rods A503 are slidably connected inside the guide grooves 502. Multiple sets of slide rods B504 are provided, and these slide rods B504 are slidably inserted into the side wall of the fixed seat 4, with each slide rod B504 fixedly connected to its corresponding slide rod A503. Multiple sets of abutment seats 6 are evenly installed in the motor housing placement mechanism 2, supporting multiple sets of slide rods B504. On the 4th, multiple sets of abutment seats 6 are driven by the adjustment component to synchronously converge or move away from each other radially along the corresponding groove 401; multiple sets of rivet joints 7 are evenly installed on multiple sets of slide rods B504 in the riveting mechanism 3. Multiple sets of rivet joints 7 are driven by the adjustment component to synchronously converge or move away from each other radially along the corresponding groove 401. A telescopic rod is installed in the relief groove 501 on the rotating seat 5 in the riveting mechanism 3. A pressure plate 702 is installed at the bottom of the telescopic rod. The telescopic rod consists of a sleeve installed in the relief groove 501, a sleeve rod that slides to connect the inner wall of the sleeve, and a spring installed inside the sleeve. The other end of the spring is connected to the sleeve rod.

[0016] Furthermore, multiple sets of sliding rods are integrally formed on the rotating seat 5, and the multiple sets of sliding rods are evenly distributed on the rotating seat 5. Correspondingly, annular grooves are opened in the groove 401. The ends of the multiple sets of sliding rods away from the rotating seat 5 are slidably connected to the annular grooves, thereby improving the rotational stability of the rotating seat 5 along the fixed seat 4.

[0017] Furthermore, a guide opening 402 is provided on the side wall of the fixed base 4, and the cross-section of the slide rod B504 is square. The slide rod B504 is slidably connected to the guide opening 402. The square shape avoids the slide rod B504 from rotating and interfering with the adjustment when it slides along the fixed base 4.

[0018] Furthermore, the motor housing placement mechanism 2 has at least three sets of guide grooves 502, slide bars A503 and B504 in the adjustment components to ensure three-point positioning of the motor housing and guarantee its stability. The number of guide grooves 502, slide bars A503 and B504 in the adjustment components of the riveting mechanism 3 can be preset according to the number of riveting points on the micro motor end cover, supporting single-point and multi-point synchronous riveting, improving adaptability and work efficiency. The abutting end of the abutting seat 6 is arc-shaped and equipped with an anti-slip pad. Pressure sensors are installed between the abutting end of the abutting seat 6 and between the riveting head 7 and the socket B701 to monitor the contact pressure in real time, preventing excessive pressure from damaging the workpiece or insufficient pressure from causing positioning or riveting failure.

[0019] In this embodiment, the micro motor housing is placed into the groove 401 in the motor housing placement mechanism 2, so that the rotor shaft of the micro motor is placed in the clearance groove 501 of the rotating seat 5, thereby initially limiting the micro motor. Then, the controller starts the drive to drive the rotating seat 5 to rotate. As the rotating seat 5 rotates, it pushes the slide bar A503 through the guide groove 502, causing multiple sets of slide bars B504 to radially converge, thereby driving multiple sets of abutment seats 6 to fit the arc-shaped ends against the outer wall of the housing. After the pressure sensor feedback that the pressure reaches the standard, it stops, thereby clamping and limiting the stability of the micro motor to avoid displacement interference during subsequent riveting. According to the size of the micro motor to be riveted, the controller starts the drive mechanism in the riveting mechanism 3 to drive multiple sets of rivet joints 7 to synchronously converge radially or move away from each other, so that the rivet joints 7 and the micro motor are aligned. The upper riveting point is adapted, and the adjustment component can be set to accommodate the clamping or riveting of micro motors of different sizes, making it more widely applicable and convenient and quick to adjust. Place the end cap aligned with the end of the housing, ensuring that the riveting point on the end cap coincides with the riveting point on the micro motor housing. At this time, the riveting point corresponds to the riveting head 7 in the riveting mechanism 3. The controller starts the lifting component 101 to drive the riveting mechanism 3 to descend. The pressure plate 702 contacts the end cap first. As the riveting mechanism 3 continues to move down, the telescopic rod is compressed, which in turn drives the pressure plate 702 to press the end cap tightly onto the micro motor to prevent displacement. After the riveting head 7 contacts the end cap, pressure is applied according to the preset stroke to complete the riveting. After the riveting is completed, the lifting component 101 rises, and the adjustment component drives the abutment seat 6 and the riveting head 7 to move away synchronously, and the finished product is taken out.

[0020] Example 2, as Figure 2 and Figure 4As shown, the riveting device for the end cap of a micro motor proposed in this utility model, compared with Embodiment 1, has a slot 505 on one end of the slide bar B504 located inside the groove 401, and a socket A601 integrally formed on the end of the abutment seat 6 away from the abutment end. The socket A601 is inserted into the corresponding slot 505, and the socket A601 and the slot 505 are fixed together by fastening bolts. A socket B701 is detachably installed on the riveting head 7 by bolts. The socket B701 is inserted into the corresponding slot 505, and the socket B701 and the slot 505 are fixed together by fastening bolts.

[0021] In this embodiment, the abutment seat 6 and the rivet joint 7 are pre-set with multiple models. According to the motor model, the fastening bolts are removed, and the appropriate abutment seat 6 or rivet joint 7 is replaced. The abutment seat 6 and the rivet joint 7 are inserted into the slot 505 through the socket A601 and the socket B701, and then fixed with the fastening bolts. According to the number of riveting points, the number of installation groups of the slide bar B504 and the rivet joint 7 in the riveting mechanism 3 is confirmed. The angle of the rotating seat 5 is adjusted by setting the encoder. The workpiece placement, positioning, riveting, and resetting steps in Embodiment 1 are repeated to complete the riveting of motor end caps of different specifications.

[0022] 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.
