Description

Technical Field

[0001] This utility model relates to the technical field of micro motor production and processing equipment, and in particular to a housing riveting device for micro motor production that is easy to adjust. Background Technology

[0002] Micromotors are key power components in automated equipment, precision instruments, and consumer electronics, and their production process demands high precision and efficiency. In the manufacturing of micromotor housings, riveting is a crucial step, used to connect or shape certain parts of the housing. The riveting device is the core equipment for this process, and its performance directly impacts product quality and production efficiency.

[0003] Before riveting, a clamping mechanism is needed to securely fix the micro motor housing to the worktable. However, there are many models of micro motors on the market with varying sizes, which requires the clamping mechanism of the riveting device to have good adjustability to adapt to workpieces of different specifications. Currently, the clamping mechanisms equipped in some conventional riveting devices are inconvenient to adjust.

[0004] For example, many fixture spacing adjustments rely on manually moving each clamping block and tightening it with bolts. This method is not only cumbersome and time-consuming, but also makes it difficult to ensure precise positioning and alignment of the two fixtures, easily leading to clamping errors and affecting subsequent riveting accuracy. When frequent changes between different batches of motor products are required for production, this inefficient adjustment method will severely slow down the production pace, becoming a bottleneck restricting overall production efficiency. At the same time, the stability of the fixture's position after locking is also crucial to the riveting quality. If the locking structure is unreliable, the impact vibrations generated during riveting may cause the fixture to loosen, leading to workpiece displacement and defective products.

[0005] Therefore, this utility model proposes a housing riveting device for micro motor production that is easy to adjust, in order to overcome the shortcomings of the prior art. Utility Model Content

[0013] 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.

[0014] Reference Figures 1-5 The present invention provides an embodiment of a micro motor housing riveting device that is easy to adjust, comprising a worktable 8, and a riveting mechanism and a clamping assembly 5 disposed above the worktable 8. The worktable 8 serves as the mounting base for the entire device, and the riveting mechanism is used to perform riveting operations on the micro motor housing. The riveting mechanism includes a threaded rod 2, a movable plate 1, and a riveting body 7. The threaded rod 2 is fixedly connected to the frame above the worktable 8. The movable plate 1 is connected to the threaded rod 2 to achieve up-and-down reciprocating motion. The riveting body 7 is fixedly connected to the bottom of the movable plate 1. The bottom of the riveting body 7 is detachably connected to a riveting head 3, and the bottom end of the riveting head 3 is fixedly connected to a cutting head 6. The clamping assembly 5 is used to quickly adjust and stably clamp the micro motor housing placed on the worktable 8. The clamping assembly 5 includes a gear 512, a first moving column 505, a turntable 511, a locking tooth 516 and a first handle 501 and a second handle 503 respectively connected to the turntable 511 and the locking tooth 516 in a transmission connection. Gear 512 is rotatably connected inside the worktable 8. Two first moving columns 505 mesh with gear 512 through rack and pinion transmission, so that when gear 512 rotates, it can drive the two first moving columns 505 to move synchronously towards each other or away from each other. A first moving block 506 is fixedly connected to the front end of each first moving column 505, and a clamp 507 is fixedly connected to the top of the first moving block 506. Turntable 511 is rotatably connected to the inside of workbench 8. Gear 512 is fixedly connected to the lower end of turntable 511. First handle 501 is connected to turntable 511. By operating first handle 501, turntable 511 and gear 512 can be driven to rotate synchronously, thereby adjusting the distance between the two clamps 507. The locking tooth 516 is rotatably connected to the inside of the worktable 8. The end of the locking tooth 516 is designed to engage or disengage with the teeth on the outer periphery of the gear 512. The second handle 503 is connected to the locking tooth 516 via the second moving block 518. Operating the second handle 503 can drive the locking tooth 516 to rotate, thereby locking or unlocking the gear 512. The first handle 501 is located in the first groove 502 on the side wall of the workbench 8, which makes it convenient for the operator to rotate. The second handle 503 is located in the second groove 504 on the side wall of the workbench 8, which makes it convenient for the operator to turn. The first moving column 505 is slidably connected to the third groove 508 inside the worktable 8. The third groove 508 provides precise guidance for the linear reciprocating motion of the first moving column 505. The locking tooth 516 is rotatably connected around the axis of the third fixed post 517. The second moving block 518 is slidably connected in the fourth groove 519 on the inner wall of the worktable 8. The second handle 503 is fixedly connected to the second moving block 518. The second moving block 518 is drivenly connected to the locking tooth 516. By moving the second handle 503, the second moving block 518 is driven to slide in the fourth groove 519, thereby driving the locking tooth 516 to rotate around the axis of the third fixed post 517. To enable the locking tooth 516 to automatically reset and lock the gear 512, the clamping assembly 5 also includes a second spring 514. One end of the second spring 514 is fixedly connected to the locking tooth 516, and the other end is fixedly connected to the second fixing post 515 inside the worktable 8. The second fixing post 515 is fixed to the outer wall of the first fixing post 513. When the second handle 503 is moved to release the lock, the second spring 514 is stretched. When the second handle 503 is released, the rebound force of the second spring 514 will drive the locking tooth 516 to automatically reset and mesh with the gear 512. To provide cushioning during workpiece clamping and prevent damage to the workpiece, at least one of the clamps 507 is connected to a second moving column 509 at its rear. The second moving column 509 is slidably connected inside the worktable 8. The rear end of the second moving column 509 abuts against one end of the first spring 510, while the other end of the first spring 510 is fixed to the inner wall of the worktable 8. When the clamp 507 contacts the workpiece and continues to be squeezed, the second moving column 509 will compress the first spring 510, and the elastic force generated by the first spring 510 will be used to achieve flexible clamping. As a preferred embodiment, in order to enable quick replacement of the riveting head 3 and improve production flexibility, the riveting head 3 is detachably connected to the bottom of the riveting body 7 via the quick-release assembly 4; Specifically, the quick-release assembly 4 includes a first fixing ring 401, a sealing ring 403, a fixing tooth 402, and a second fixing ring 404. The first fixing ring 401 is sleeved on the top of the riveting head 3 and is used to cooperate with the mounting groove of the riveting body 7. The sealing ring 403 is a ring made of an elastic material and is sleeved on the outer periphery of the first fixing ring 401. The fixing tooth 402 is disposed between the sealing ring 403 and the second fixing ring 404. The second fixing ring 404 is rotatably sleeved on the outer periphery of the fixing tooth 402 and the sealing ring 403. The inner wall of the second fixing ring 404 is provided with a cam track, and the fixing tooth 402 is provided with a protrusion that cooperates with the cam track. When the second fixing ring 404 is rotated, the cam track on the inner wall will drive the protrusion on the fixing tooth 402, causing the fixing tooth 402 to move radially contracting or expanding. When contracting, the fixing tooth 402 will squeeze the sealing ring 403 inward, causing the sealing ring 403 to be deformed by pressure and tightly hold the first fixing ring 401, thereby firmly locking the riveting head 3 on the riveting body 7. Reverse rotation will release the pressure and achieve quick disassembly.

[0015] Working principle: Before clamping the micro motor housing, the second handle 503 located in the second groove 504 is first moved. The second handle 503 drives the second moving block 518 to slide in the fourth groove 519, thereby driving the locking tooth 516 to rotate around the axis of the third fixed post 517, so that the end of the locking tooth 516 disengages from the gear 512. At this time, the gear 512 is in an unlocked state that can rotate freely. Next, rotate the first handle 501 located in the first groove 502. The first handle 501 drives the turntable 511 and the fixedly connected gear 512 to rotate. The gear 512 drives the two first moving columns 505 to move synchronously towards or away from each other in the third groove 508 through rack and pinion transmission. This causes the first moving block 506 and the clamp 507 to quickly adjust the spacing to the appropriate position. Then, release the second handle 503. Under the elastic force of the second spring 514, the locking teeth 516 automatically reset and mesh with the gear 512, locking the spacing of the clamp 507. Place the micro motor housing between the two clamps 507, and slightly rotate the first handle 501 again to clamp the housing with the clamps 507. When the clamps 507 contact the housing, the second moving column 509 on one side will be pressed and compress the first spring 510. The elastic force provided by the first spring 510 achieves stable and flexible clamping of the housing. Then, by rotating the threaded rod 2, the moving plate 1, the riveting body 7 and the riveting head 3 are driven to descend, and the riveting operation is completed by the cutter head 6. When it is necessary to replace the rivet head 3, rotate the second retaining ring 404 in the quick-release assembly 4 in the opposite direction. The second retaining ring 404 drives the retaining teeth 402 to expand radially, releasing the compression on the sealing ring 403, so that the old rivet head 3 can be easily removed and replaced with a new one.
