Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0022] In the present invention, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Embodiment 1: Refer to Figures 1-6 , the present invention provides a technical solution: a micro-miniature deep groove ball bearing inner ring butt joint installation auxiliary device, including a bottom plate 1, an installation mechanism 1 is rotatably connected inside the bottom plate 1, a bearing inner ring 4 is clamped on the outer surface of the installation mechanism 1, a rolling element 5 is clamped on the outer surface of the bearing inner ring 4, a cage 7 is clamped on the outer surface of the rolling element 5, an installation mechanism 2 is fixedly connected to the upper surface of the bottom plate 1, a bearing outer ring 2 is clamped on the outer surface of the installation mechanism 2, and an auxiliary mechanism 8 is clamped inside the bottom plate 1. The installation mechanism 1 includes: A first screw 301, the first screw 301 is rotatably connected to the bottom plate 1, a slider plate 302 is threadedly connected to the outer surface of the first screw 301, a rotating column 1 303 is rotatably connected inside the slider plate 302, a threaded column 1 304 is fixedly connected to the outer surface of the rotating column 1 303, a through-hole cylinder 309 is threadedly connected to the outer surface of the threaded column 1 304, and a bellows 1 310 is fixedly connected to the outer surface of the through-hole cylinder 309. The bellows 1 310 is used to protect the threaded column 1 304.

[0024] The installation mechanism 1 further includes a through-hole frame 305, the outer surface of the threaded column 1 304 is fixedly connected to the outer surface of the through-hole frame 305, a first rotating shaft 306 is fixedly connected inside the through-hole frame 305, a bent metal plate 307 is rotatably connected to the outer surface of the first rotating shaft 306, a rubber bent plate 308 is fixedly connected to the outer surface of the bent metal plate 307, and the rotating column 1 303 is used to rotate the threaded column 1 304.

[0025] The outer surface of the first rotating column 303 is provided with a friction surface. The outer surface of the first corrugated pipe 310 is fixedly connected to the outer surface of the through-hole frame 305. The outer surface of the first rotating column 303 is in contact with the outer surface of the through-hole frame 305. The outer surface of the rubber bent plate 308 is in contact with the inner wall of the bearing inner ring 4. The bent metal plate 307 can be bent outwards to push the rubber bent plate 308. The first threaded column 304 is used to adjust the bent metal plate 307. During the inward bending process of the bent metal plate 307, the bent parts on both sides gradually approach, and the horizontal part correspondingly generates a displacement change. Due to the good rigidity and ductility of the metal, although deformation occurs during bending, the overall structure remains stable, providing a reliable support for subsequent pushing. The setting of the rubber bent plate 308 enables it to clamp and center without damaging the inner wall of the bearing inner ring 4, and ensures the stable rotation of the first threaded column 304 through the first corrugated pipe 310.

[0026] The second mounting mechanism 6 includes a through-hole plate 601. One of the through-hole plates 601 is fixedly connected to the upper surface of the bottom plate 1. The outer surface of the through-hole plate 601 is fixedly connected with a first arc-shaped plate 602. The outer surface of the through-hole plate 601 is fixedly connected with a protective cover 603. A worm 604 is slidably connected inside the protective cover 603. The outer surface of the worm 604 is fixedly connected with a second arc-shaped plate 605. The outer surface of the second arc-shaped plate 605 is fixedly connected with a rubber plate 606. The rubber plate 606 is used to limit the bearing outer ring 2.

[0027] The second mounting mechanism 6 further includes a worm gear 608. The worm gear 608 is in gear connection with the worm 604. The outer surface of the protective cover 603 is fixedly connected with a second corrugated pipe 607. The outer surface of the worm gear 608 is in gear connection with a gear set 609. The outer surface of the gear set 609 is in gear connection with a motor 610. The second corrugated pipe 607 is used to protect the worm 604.

[0028] The worm 604 is inserted into the second corrugated pipe 607. The worm gear 608 and the gear set 609 are both rotatably connected to the first arc-shaped plate 602. The motor 610 is rotatably connected to the first arc-shaped plate 602. The outer surface of the rubber plate 606 is in contact with the outer surface of the bearing outer ring 2. The motor 610 is used to drive the gear set 609. The central gear of the gear set 609 is hollow and has the same diameter as the through-hole of the protective cover 603, so as to ensure that when docking the bearing outer ring 2 and the bearing inner ring 4, the first mounting mechanism 3 can be inserted into the through-hole, without affecting the docking of the bearing outer ring 2 and the bearing inner ring 4, and when docking a smaller bearing, the first mounting mechanism 3 can cooperate with the second mounting mechanism 6 without mutual collision, and ensure the stable rotation of the worm 604 through the second corrugated pipe 607.

[0029] The working principle of this embodiment is as follows: When using this kind of auxiliary device for butt-joint installation of the inner ring of a miniature deep groove ball bearing, the bearing inner ring 4 with rolling elements 5 and a cage 7 is inserted on the surface of the rubber bent plate 308 and centered. At this time, rotate the first rotating column 303 to drive the first threaded column 304 to rotate. Through the threaded connection between the first threaded column 304 and the through-hole cylinder 309, the first threaded column 304 and the through-hole cylinder 309 gradually coincide. At this time, through the restriction of the through-hole frame 305 and the first rotating shaft 306 on the bent metal plate 307, the bent part gradually approaches, the horizontal part moves outward, and the rubber bent plate 308 is pushed outward. At this time, driven by the first threaded column 304, the horizontal parts of the four groups of symmetrically arranged bent metal plates 307 are evenly pushed outward, so as to achieve centering while clamping the bearing inner ring 4. At this time, hold the bearing outer ring 2 and place it within the horizontal range of the rubber plate 606. At this time, driven by the motor 610 and through the transmission of the gear set 609, the worm gear 608 rotates and drives the worm 604 to move inward, thereby pushing the second arc-shaped plate 605 to move inside the protective cover 603, so that the rubber plate 606 contacts the outer surface of the bearing outer ring 2. At this time, driven by the motor 610, the three sets of rubber plates 606 provided move inward evenly, so as to achieve centering while clamping the bearing outer ring 2 and make it coincide with the axis of the bearing inner ring 4 to ensure the accuracy of butt-joint. At this time, driven by the first screw 301, the slider plate 302 moves inward, so that the bearing inner ring 4 with rolling elements 5 and a cage 7 is butt-jointed with the bearing outer ring 2.

[0030] Embodiment 2: Please refer to Figures 7-8 , on the basis of Embodiment 1, the present invention provides a technical solution: The auxiliary mechanism 8 includes a slider frame 801, the slider frame 801 is threadedly connected to the first screw 301, a second threaded column 802 is rotatably connected inside the slider frame 801, a bolt hole 804 is opened inside the second threaded column 802, a telescopic baffle 805 is fixedly connected to the outer surface of the slider frame 801, a first clamping block 803 is clamped inside the slider frame 801, a rotating sleeve 806 is rotatably connected inside the first clamping block 803, a second rotating column 807 is threadedly connected inside the rotating sleeve 806, and a supporting bent plate 808 is fixedly connected to the upper surface of the second rotating column 807. The telescopic baffle 805 is used to protect the slider frame 801.

[0031] The outer surface of the slider frame 801 is in contact with the upper surface of the bottom plate 1. The outer surface of the telescopic baffle 805 is fixedly connected to the outer surface of the first clamping block 803. The second threaded column 802 is threadedly connected to the first clamping block 803. The outer surface of the support bent plate 808 is in contact with the outer surface of the rubber bent plate 308. The support bent plate 808 is used to support the rubber bent plate 308. When the first clamping block 803 moves inside the slider frame 801, the telescopic baffle 805 ensures the stable movement of the first clamping block 803. Both the slider plate 302 and the bottom of the through-hole plate 601 are provided with clamping grooves to prevent affecting the movement of the slider frame 801 following the installation mechanism 1. The position of the first clamping block 803 is adjusted through the bolt hole 804, and the position of the first clamping block 803 is limited. When the docking auxiliary device is not in use, the support bent plate 808 can assist in supporting the rubber bent plate 308, ensuring the centering accuracy and extending the service life.

[0032] The working principle of this embodiment is as follows: When using this kind of micro-miniature deep groove ball bearing inner ring docking and installation auxiliary device, when inserting the bearing inner ring 4 with the rolling elements 5 and the cage 7 on the surface of the rubber bent plate 308 and placing it in the center, bolts can be inserted through the bolt hole 804, thereby realizing the rotation of the second threaded column 802, so that the first clamping block 803 moves inside the slider frame 801, and the position of the support bent plate 808 is adjusted through the rotating sleeve 806 and the second rotating column 807. Thus, when the installation mechanism 1 centers and clamps the bearing inner ring 4, by rotating the rotating sleeve 806, the second rotating column 807 pushes the support bent plate 808 upward to move, so that the support bent plate 808 limits the position of the inserted bearing inner ring 4, realizing the ability to place it in the center, ensuring the stability and accuracy of the centering and clamping of the installation mechanism 1. From the contact between the support bent plate 808 and the rubber bent plate 308, the auxiliary support for the installation mechanism 1 is realized, thereby ensuring that the installation mechanism 1 will not be eccentric due to the bearing inner ring 4 with the rolling elements 5 and the cage 7, and through the threaded connection between the slider frame 801 and the first screw 301, it can move following the movement of the installation mechanism 1, thereby realizing the docking of the bearing outer ring 2 and the bearing inner ring 4.
