DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described in detail below in conjunction with specific embodiments: Example 1

[0028] See also Figure 1-9 A press-fitting device for assembling an electromagnetic brake comprises a press-fitting platform 1, a support frame 2 is fixed on the press-fitting platform 1, a mounting groove 12 for the electromagnetic brake 4 to be clamped is provided on the press-fitting platform 1, a guide sleeve 6 for placing a bearing 5 is fixed on the press-fitting platform 1, the guide sleeve 6 corresponds vertically to the mounting groove 12, two symmetrically arranged support plates 27 are radially slidably installed on the guide sleeve 6, an elastic positioning component for limiting the position of the support plate 27 is installed on the guide sleeve 6, a lifting frame 7 is vertically slidably installed on the support frame 2, a vertically arranged rotating shaft 18 is rotatably installed on the lifting frame 7, and a rotating sleeve 1 is slidably sleeved on the rotating shaft 18 7. A vertical spring 46 is fixed between the rotating sleeve 17 and the rotating shaft 18. A clamping strip 44 fixed to the side wall of the rotating shaft 18 is slidably installed on the inner wall of the rotating sleeve 17. A rotating transmission component for driving the rotating shaft 18 to rotate is installed on the lifting frame 7. A rotating frame 11 vertically corresponding to the bearing 5 is fixed to the bottom of the rotating sleeve 17. An inner support clamping component for clamping the inner ring of the bearing 5 is slidably installed on the rotating frame 11. A cylinder 3 is fixed on the support frame 2. A servo motor 13 is fixed on the press-fitting table 1. The output shaft of the servo motor 13 is driven and connected to a counter-clamping component for fixing the electromagnetic brake 4.

[0029] When assembling the electromagnetic brake 4 and the bearing 5 , the electromagnetic brake 4 is placed on the mounting groove 12 , the electromagnetic brake 4 is clamped and fixed by the opposing clamping components, the bearing 5 is placed inside the guide sleeve 6 , and the bearing 5 is supported by the support plate 27 .

[0030] The downward movement of the lifting frame 7 can drive the rotating shaft 18 to move vertically downward, so that the rotating sleeve 17 and the rotating frame 11 move downward, and the inner support clamping assembly limits the inner ring of the bearing 5. The inner support clamping assembly and the downward movement of the rotating frame 11 can realize the vertical downward pressure on the bearing 5, so that the bearing 5 enters the electromagnetic brake 4 for assembly.

[0031] Specifically, the internal support clamping assembly includes a translation frame 28 slidably mounted on the rotating frame 11, a connecting spring 33 is fixed between the translation frame 28 and the rotating frame 11, an internal support block 29 is fixed to the bottom of the translation frame 28, a wedge surface 32 opposite to the bearing 5 is provided on the internal support block 29, and a push inclined surface 43 corresponding to the rotation of the internal support block 29 is provided on the support plate 27.

[0032] When the rotating frame 11 moves downward, the inner support block 29 moves downward vertically, and the wedge surface 32 of the inner support block 29 slides against the bearing 5. At this time, the inner support block 29 slides toward the rotating sleeve 17. When the wedge surface 32 passes over the lower end of the bearing 5, under the elastic action of the connecting spring 33, the inner support block 29 clamps the inner ring of the bearing 5 from the inside, and the inner support block 29 can support the bottom end of the bearing 5, which effectively ensures the stability of the pressing process of the bearing 5 and improves the pressing quality of the bearing 5.

[0033] The rotating transmission assembly of the device includes a bevel gear I8 rotatably mounted on the lifting frame 7, the bevel gear I8 is meshed with a bevel gear II9, the bevel gear II9 is ​​coaxially fixed with the rotating shaft 18, a rotating gear 19 is coaxially fixed on the bevel gear I8, and the rotating gear 19 is meshed with a fixed rack 20 vertically fixed on the support frame 2.

[0034] During the vertical downward movement of the lifting frame 7, the rotating gear 19 moves vertically downward and meshes with the fixed rack 20 to realize rotation. The rotating gear 19 drives the bevel gear I8 to rotate, and the bevel gear I8 drives the bevel gear II9 meshing therewith to rotate. The bevel gear II9 drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the rotating sleeve 17 to rotate through the clamping strip 44, so that the rotating frame 11 can rotate, that is, when the rotating frame 11 pushes the bearing 5 downward, the force position of the rotating frame 11 on the upper end surface of the bearing 5 is automatically adjusted, so as to ensure that the bearing 5 is stably stressed, avoid the bearing 5 from tilting, and greatly improve the press-fitting quality of the bearing 5. Example 2

[0035] See also Figure 1-9On the basis of Example 1, in addition, the elastic positioning component of the device includes a fixed plate 39 fixed on the guide sleeve 6, a connecting plate 38 is vertically slidably installed on the fixed plate 39, a push spring 37 is fixed between the connecting plate 38 and the fixed plate 39, a positioning block 40 is fixed at the lower end of the connecting plate 38, two triangular grooves 41 are provided on the support plate 27 to be plugged with the positioning block 40, a vertical plate 45 is fixed at the bottom of the support plate 27, and a traction spring 42 is fixed between the vertical plate 45 and the guide sleeve 6.

[0036] During the rotation of the rotating frame 11, the inner support block 29 rotates accordingly, and the inner support block 29 pushes the push inclined surface 43 of the support plate 27, so that the support plate 27 slides away from the bearing 5. Under the elastic push action of the push spring 37, the positioning block 40 switches from the originally inserted triangular groove 41 to another triangular groove 41 to position the push inclined surface 43. At this time, the inner support block 29 supports the bearing 5, so that the bearing 5 can move downward stably without being blocked by the support plate 27.

[0037] In addition, a cylinder 3 is fixed on the pressing table 1 of the device, a vertically arranged sliding frame 23 is fixed on the free end of the cylinder 3, a sliding rack I24 is fixed on the sliding frame 23, a sliding rack II25 is fixed on the lifting frame 7, a central gear 26 meshing with the sliding rack I24 and the sliding rack II25 is rotatably installed on the support frame 2, a push ring plate 21 is fixed on the sliding frame 23, and the push ring plate 21 vertically corresponds to the wedge surface 32.

[0038] Through the provided cylinder 3, the cylinder 3 can drive the sliding frame 23 and the sliding rack I24 to move vertically, the sliding rack I24 drives the central gear 26 to rotate, the central gear 26 drives the sliding rack II25 to move, and the sliding rack II25 drives the lifting frame 7 to lift and slide, thereby realizing the vertical movement of the rotating frame 11 and pressing the bearing 5 and the electromagnetic brake 4.

[0039] In addition, an extension plate 31 is fixed on the rotating sleeve 17, a rotating frame 30 is rotatably mounted on the extension plate 31, a torsion spring 34 is fixed between the rotating frame 30 and the extension plate 31, a wedge block 35 is fixed at one end of the rotating frame 30, and a push plate 36 horizontally opposite to the wedge block 35 is fixed on the translation frame 28.

[0040] After the electromagnetic brake 4 and the bearing 5 are assembled, the wedge surface 32 is pushed during the upward movement of the push ring plate 21, so that the inner support block 29 slides toward the rotating sleeve 17, and then the push plate 36 fixed on the inner support block 29 pushes the wedge block 35, so that the wedge block 35 drives the rotating frame 30 to rotate. When the push plate 36 passes over the wedge block 35, the rotating frame 30 is reset under the torsion action of the torsion spring 34, and then the push plate 36 and the translation frame 28 are temporarily locked. At this time, the wedge surface 32 does not contact the bearing 5, and the sliding frame 23 is driven downward by the cylinder 3 to realize the push ring plate 21 away from the electromagnetic brake 4. At the same time, the rotating frame 11 moves upward and moves out of the electromagnetic brake 4, so that the electromagnetic brake 4 is conveniently removed from the press-fitting table 1.

[0041] In addition, a reset ring 10 is fixed on the support frame 2 and is sleeved on the outside of the rotating sleeve 17. The reset ring 10 vertically corresponds to the end of the rotating frame 30 away from the wedge block 35. When the rotating frame 11 moves up to the rotating frame 30 and is pushed by the reset ring 10, the rotating frame 11 rotates to separate it from the push plate 36, and is reset under the elastic action of the connecting spring 33, which is convenient for the next assembly operation of the electromagnetic brake 4 and the bearing 5.

[0042] The opposing clamping components of the device include two threaded rods 14 coaxially fixed to the output shaft of the servo motor 13, the threads of the two threaded rods 14 have opposite rotation directions, each threaded rod 14 is threadedly sleeved with a threaded sleeve block 15 slidably connected to the press-fitting table 1, a clamping block 16 is fixed to the threaded sleeve block 15, and the clamping block 16 is provided with a clamping inclined surface 22 that abuts against the electromagnetic brake 4.

[0043] After the electromagnetic brake 4 is installed on the press-fitting table 1, the servo motor 13 drives the threaded rod 14 to rotate, and the threaded rod 14 drives the threaded sleeve 15 to move. At this time, the two threaded sleeves 15 approach each other, thereby achieving the clamping inclined surfaces 22 approaching each other and clamping the electromagnetic brake 4, which greatly improves the stability of the assembly process of the electromagnetic brake 4 and the bearing 5.

[0044] In summary, the inner support block 29 provided in the present invention can clamp the inner ring of the bearing 5, so that the rotating frame 11 can drive the inner ring of the bearing 5 to rotate, and achieve the guiding effect of the pressing process of the bearing 5 by means of its own structure, and the rotating frame 11 can rotate when vertically moving downward to press the bearing 5, so as to achieve uniform pressure on different axial positions of the bearing 5, greatly improving the press-fitting stability of the bearing 5 and the electromagnetic brake 4, and significantly improving the assembly quality of the electromagnetic brake 4. Before the inner support block 29 of the present invention provides internal support for the bearing 5, it can provide preliminary support for the bearing 5 inside the guide sleeve 6 before press-fitting, and when the inner support block 29 pushes the bearing 5, since the inner support block 29 drives the rotation of the inner ring of the bearing 5, the inner support block 29 supports the bottom of the bearing 5 after the support plate 27 is away from the bearing 5, which plays a stable limiting effect on the bearing 5, and further improves the assembly stability of the bearing 5 and the electromagnetic brake 4.
