Description

Technical Field

[0001] This utility model relates to the technical field of motor processing equipment, and more particularly to a stable pressing mechanism for a micro motor housing and magnetic strip. Background Technology

[0002] In the assembly process of a micro motor, sheet-like magnetic strips need to be wound into a circle and pressed into the inner cavity of the housing. In existing assembly equipment, the housing is mounted above the magnetic strip and fixed to a mounting base. The left and right sides of the mounting base are fixed to a bracket with screws.

[0003] To adjust the concentricity of the housing and the magnetic strip, the screws are first loosened, then the mounting base is moved for fine-tuning before tightening the screws again. This adjustment method is not only very inconvenient, but also cannot guarantee precise concentricity. Furthermore, the mounting base is only fixed to the bracket by screws on the left and right sides. After repeated pressing and impact between the magnetic strip and the housing, the mounting base may loosen, causing concentricity to shift.

[0004] If the housing and the rack cannot be concentric, the magnetic strip will rub against the inner wall of the housing, leading to decreased motor performance, increased vibration, or even failure. Utility Model Content

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] This embodiment provides a stable pressing mechanism for a micro motor housing and a magnetic strip. In this embodiment, it includes a support assembly and a pressing mechanism. The support assembly is provided with a mounting station for mounting the housing 1. The magnetic strip is located below the mounting station. The pressing mechanism is used to drive the magnetic strip to lift and press it into the inner cavity of the housing 1.

[0033] like Figure 1 and Figure 2 As shown, the support assembly includes a fixed component and a movable component. The movable component includes a base 2 and a base plate 3. The outer shell 1 is mounted on the base 2, and the base 2 is movably mounted on the base plate 3 and can translate relative to the base plate 3 in the X direction. The base plate 3 is movably mounted on the fixed component and can translate relative to the fixed component in the Y direction. The coordinated displacement of the base 2 and the base plate 3 allows for the adjustment of the horizontal position of the outer shell 1, ensuring that the outer shell 1 and the magnetic strip are vertically coaxial. By translating the base 2 left and right and the base plate 3 forward and backward, the horizontal position of the outer shell 1 can be adjusted, bringing the outer shell 1 and the magnetic strip to the same axis. The adjustment method is simple, convenient, quick, precise, and stable.

[0034] The base 2 is provided with a horizontal adjustment plane one, which is fitted and assembled with the base plate 3. The base 2 can be translated relative to the base plate 3 through the adjustment plane one. The base plate 3 is provided with a horizontal adjustment plane two, which is fitted and assembled with a fixing component. The base plate 3 can be translated relative to the fixing component through the adjustment plane two. By using the horizontal adjustment plane one and adjustment plane two for fine-tuning and installation fixation, compared with the side-fixed adjustment method in the prior art, the horizontal adjustment plane of this utility model can make the adjustment more precise and stable, the connection more secure, and reduce loosening caused by pressing and impact.

[0035] The fasteners are fixed to the frame of the motor assembly equipment. The fasteners include a front support block 4 and a rear support block 5, which are spaced apart. The front and rear ends of the base plate 3 are respectively mounted on the front support block 4 and the rear support block 5. The base 2 has several oblong holes 6, each extending along the X-direction. The base plate 3 has several oblong holes 7, each extending along the Y-direction. The base plate 3 also has an adjustment groove 8, into which the base 2 is embedded and can move along the X-direction. A protrusion 9 integrally formed with the base 2 is fixed to the bottom of the base 2. A through hole 10 extending vertically through the base plate 3 is provided, through which the protrusion 9 extends beyond the base plate 3. The aforementioned installation position is located on the protrusion 9.

[0036] like Figure 3 and Figure 4 As shown, the base 2 is provided with a magnetic fixing component for fixing the outer shell 1. The magnetic fixing component includes a positioning block 11 and a driving component 12 for driving the positioning block 11 to rise and fall. The positioning block 11 is connected to the end of the driving component 12 through a connecting rod 13. The driving component 12 drives the positioning block 11 to descend, attract, fix, and position the outer shell 1. Several magnetic blocks are fixedly embedded in the bottom of the positioning block 11. After the positioning block 11 descends, it abuts against the outer shell 1 and is magnetically fixed to the outer shell 1 through the magnetic blocks. The positioning block 11 is also provided with a positioning hole. The outer shell 1 is provided with a protruding shaft. After the positioning block 11 descends, the shaft of the micro motor is positioned by pressure and the hole on the part, so that the shaft is inserted into the positioning hole to form a positioning. The base 2 is provided with a through hole 18 for the positioning block 11 to rise and fall. After the positioning block 11 passes through the through hole 18, it is magnetically fixed to the outer shell 1.

[0037] Because there are specific angle requirements for inserting the magnetic strip into the housing 1, after the housing 1 is transported to the installation station, it is necessary to rotate the housing 1 by 90° to the required position before inserting the magnetic strip.

[0038] The bracket assembly is also equipped with a rotary drive mechanism for driving the housing 1 to rotate vertically and adjusting the assembly angle between the housing 1 and the magnetic strip. This rotary drive mechanism includes a mounting base 14, a gear 15, and a rack 16. The mounting base 14 is fixedly mounted on the base 2. The connecting rod 13 is rotatably mounted on the mounting base 14. The gear 15 is sleeved on the outer circumference of the connecting rod 13 and fixedly connected to it. The rack 16 is horizontally slidably mounted on the mounting base 14 and meshes with the gear 15. The mounting base 14 is also equipped with a second drive component 17 for driving the rack 16 to translate and causing the gear 15, connecting rod 13, and positioning block 11 to rotate as a whole. A floating joint 25 is provided at the end of the first drive component 12, through which the connecting rod 13 is fixedly connected to the end of the first drive component 12.

[0039] like Figure 3 As shown, the rotary drive mechanism also includes an angle limiting component for limiting the rotation range of the housing 1. This angle limiting component includes a limiting block 19, an adjusting block 20, and limiting screws 21. The limiting block 19 is sleeved on the outer periphery of the connecting rod 13 and fixedly connected to it. The adjusting block 20 is fixedly mounted on the mounting base 14. Two limiting screws 21 are spaced apart and screwed onto the adjusting block 20, with the ends of the limiting screws 21 facing the adjusting block 20. The connecting rod 13 drives the limiting block 19 to rotate synchronously. The limiting block 19 has two abutment surfaces 22. When the limiting block 19 rotates, the two abutment surfaces 22 can rotate to abut against the two limiting screws 21. By rotating the adjusting screws, their positions are moved, thereby limiting the rotation angle of the housing 1.

[0040] The first driving component 12 and the second driving component 17 are cylinders. The first driving component 12 is fixed to the mounting base 14 by the first corner bracket 23, and the second driving component 17 is fixed to the mounting base 14 by the second corner bracket 24.
