Description

Technical Field

[0001] This utility model relates to the field of micro motor manufacturing technology, and in particular to an adjustable micro motor housing riveting device. Background Technology

[0002] In the production process of micro motors, the housing is riveted to securely fix rivets or press-fit parts to designated positions on the housing through physical extrusion, thereby achieving a reliable connection between the housing and other components (such as end caps, bearing seats, etc.). This process ensures precise assembly of each component, enhances the stability and sealing of the overall structure, and prevents components from loosening or falling off due to vibration, external forces, or other factors. At the same time, it can improve production efficiency, reduce problems such as thermal deformation and stress concentration that may be caused by traditional processes such as welding, and ensure the performance reliability and service life of the micro motor during operation.

[0003] Chinese Patent Publication No. CN221978765U discloses a housing riveting device for micro-motor production. The device includes a horizontal base plate. A riveting assembly for micro-motor housing production is fixedly connected to the top right side of the horizontal base plate. A load-bearing replacement assembly for holding the micro-motor rotor is rotatably connected to the top of the horizontal base plate. The load-bearing replacement assembly includes a central shaft rotatably connected to the top of the horizontal base plate. A horizontal plate, circular in shape, is fixedly connected to the top of the central shaft. The surface of the horizontal plate has a circular groove. This utility model relates to the field of riveting device technology. Before riveting, the worker can quickly connect the bottom insert rod of the placement plate to the circular groove. During riveting, simply rotating the horizontal plate 90 degrees and then starting the riveting machine completes the process. The worker has ample time and space to prepare a spare riveting structure, significantly improving riveting efficiency.

[0004] While existing technology allows the machine housing to be positioned below the riveting machine for riveting by rotating a horizontal plate during the riveting process, the rotation speed and angle of the horizontal plate are manually controlled and cannot be automatically rotated, thus reducing the work efficiency of the operators.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Reference Figure 1-5An adjustable micro motor housing riveting device includes a processing table 1, a riveting machine 2 on the top of the processing table 1, and a placement assembly 3 on the top of the processing table 1 and below the riveting machine 2. The placement assembly 3 includes a rotating shaft 301, a placement table 302, a four-jaw chuck 303, bearing balls 304, a transmission shaft 305, a gear 306, an electric push rod 307, and a rack 308. The rotating shaft 301 is rotatably connected to the top of the processing table 1, the placement table 302 is fixedly connected to the top of the rotating shaft 301, the four-jaw chuck 303 is fixedly installed on the top of the placement table 302 in a parallel arrangement, the bearing balls 304 are rotatably connected to the bottom of the rotating shaft 301, the transmission shaft 305 is fixedly connected inside the rotating shaft 301 and located inside the processing table 1, the gear 306 is fixedly connected to the side surface of the transmission shaft 305, the electric push rod 307 is fixedly installed on the right side of the processing table 1, and the rack 308 is fixedly connected to the telescopic end of the electric push rod 307.

[0025] To set up component 3, the operator first places the machine housing to be processed on top of the four-jaw chuck 303. Then, the four-jaw chuck 303 is activated to clamp and fix the machine housing. Next, the electric push rod 307 is activated, causing its extension end to drive the rack 308 to extend. During its movement, the rack 308 engages with the gear 306, thus driving the drive shaft 305, the rotating shaft 301, and the placement table 302 to rotate 180°, thereby clamping the machine housing. The machine is moved directly beneath the riveting machine 2, and the unactivated four-jaw chuck 303 moves to the operator's position. The operator then places another housing on the four-jaw chuck 303 at the designated clamping height. The riveting machine 2 is then activated to rivet the housing located directly beneath it. After riveting is complete, the electric push rod 307 is activated again, causing its telescopic end to retract the rack 308, thereby rotating the placement table 302 180° in the reverse direction for the next riveting operation. This invention, through the placement component 3, allows the rotation angle and speed of the placement table 302 to be controlled by the telescopic extension and retraction speed of the electric push rod 307. This not only effectively improves the convenience of riveting operations for operators but also significantly increases their work efficiency and simplifies operation.

[0026] Furthermore, a connecting slide 4 is slidably mounted on the top of the processing table 1. The connecting slide 4 is fixedly connected to c by bolts. A movable component 5 is provided on the top of the processing table 1 and the bottom of the connecting slide 4.

[0027] By fixing the riveting machine 2 with bolts, it is convenient for staff to maintain and repair the riveting machine 2 in the future.

[0028] Furthermore, the moving component 5 includes a limiting slide 501, a moving slide 502, a lead screw 503, a stepper motor 504, a limiting slider 505, and a threaded hole 506. The limiting slide 501 is symmetrically distributed on the top inner wall of the processing table 1, the limiting slider 505 is fixedly connected to the bottom of the connecting slide 4, and the stepper motor 504 is fixedly installed on the back of the processing table 1.

[0029] A movable slide 502 is formed on the top inner wall of the processing table 1 and is located between the limiting slides 501. A lead screw 503 is rotatably connected inside the movable slide 502. A stepper motor 504 is drivenly connected to the lead screw 503. A threaded hole 506 is formed inside the limiting slider 505 and is threadedly connected to the lead screw 503. The limiting sliders 505 are symmetrically distributed and fixedly connected to the bottom of the connecting slide 4. The limiting sliders 505 are adapted to the limiting slides 501.

[0030] The movable component 5, by activating the stepper motor 504, drives the lead screw 503 at the transmission end to rotate. During the rotation of the lead screw 503, due to the threaded connection between the threaded hole 506 and the lead screw 503, and the matching of the limiting slider 505 and the limiting groove 501, the connecting slide 4 can move back and forth. This invention, through the movable component 5, allows the connecting slide 4 and the riveting machine 2 fixed on its top to move via the rotation of the lead screw 503 driven by the stepper motor 504, thus facilitating the adjustment of the distance of the riveting machine 2 by the operator and effectively improving practicality and convenience.

[0031] Furthermore, a control button 6 is movably installed on the top of the processing table 1, and a support column 7 is fixedly connected to the bottom of the processing table 1. An anti-slip pad 8 is fixedly connected to the bottom of the support column 7.

[0032] The installation of the anti-slip mat 8 increases the friction between the device and the surface on which it is placed.

[0033] The end of the drive shaft 305 away from the rotating shaft 301 is rotatably connected to the inside of the processing table 1, and the rack 308 is meshed with the gear 306.

[0034] In summary:

[0035] In use, the riveting machine 2 is first fixedly installed on the top of the connecting slide table 4 with bolts, and the stepper motor 504 is started, so that the stepper motor 504 drives the lead screw 503 at the transmission end to rotate. During the rotation of the lead screw 503, due to the threaded connection between the threaded hole 506 and the lead screw 503, and the matching between the limiting slider 505 and the limiting slide groove 501, the connecting slide table 4 can be driven to move back and forth, thereby adjusting the position of the riveting machine 2 so that the riveting machine 2 is located directly above the placement table 302.

[0036] Next, the operator places the machine housing to be processed on top of the four-jaw chuck 303. The four-jaw chuck 303 is then activated to clamp and secure the machine housing. The electric push rod 307 is then activated, causing its extension end to extend the rack 308. During this movement, the rack 308 engages with the gear 306, thus rotating the drive shaft 305, the rotating shaft 301, and the placement table 302 180°, moving the clamped machine housing to the riveting position. Directly below the press 2, the unactivated four-jaw chuck 303 moves to the operator's front. The operator then places another housing on the four-jaw chuck 303 at the specified clamping height. The press 2 can then be restarted to rivet the housing located directly below it. After riveting is completed, the electric push rod 307 is restarted, causing the extension end of the electric push rod 307 to retract the rack 308, thereby causing the placement table 302 to rotate 180° in the opposite direction for the next riveting operation.
