Detailed Implementation

[0029] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In the description of this application, when a feature is referred to as "setting", "fixing", or "connecting" to another feature, it can be set, fixed, or connected to the other feature directly, or it can be set, fixed, or connected to the other feature indirectly.

[0031] Please see Figure 1-4 This application provides the following technical solution: a small bearing seal ring installation device, comprising:

[0032] The base assembly includes a fixedly mounted bottom base 5 and a top base 1.

[0033] Specifically, the base assembly adopts a layered design, which is structurally stable and facilitates the arrangement and coordination of various functional components, thereby improving the overall rigidity and stability of the equipment. During installation, the bottom base 5 is fixed to the workbench, and the top base 1 is connected to the bottom base through columns or frames to form a stable installation space.

[0034] Positioning component 8 is provided on the bottom base 5 and is used to fix bearing 7.

[0035] Specifically, the positioning component 8 enables rapid and precise positioning of the bearing, preventing it from shifting during installation and ensuring the alignment of the sealing ring assembly.

[0036] The expansion assembly includes a stepped column 9 disposed above the positioning assembly 8 and a cone 3 slidably disposed within the stepped column 9. The lower part of the stepped column 9 is provided with a plurality of elastic expansion claws 11 arranged around the cone 3.

[0037] Specifically, the axial movement of the cone 3 evenly expands the elastic expansion claw 11, thereby smoothly opening the sealing ring and preventing its deformation or damage.

[0038] The driving component includes a first driving component 2 and a third driving component 10 disposed on the top base 1. The first driving component 2 is connected to the cone 3 and is used to push it to move axially to expand the elastic expansion claw 11. The telescopic end of the third driving component 10 is connected to the outer side of the stepped column 9 through a connecting plate 4.

[0039] Specifically, the dual-drive design enables step-by-step control with an adjustable sequence of actions to accommodate the installation requirements of sealing rings of different specifications. The third drive component 10 pushes the stepped column 9 down to press it above the sealing ring, while the first drive component 2 then pushes the cone 3 down to complete the expansion.

[0040] The push assembly 6 is located on the bottom base 5 and is used to push the sealing ring toward the bearing 7.

[0041] Specifically, the push assembly and the expansion assembly work together to achieve an integrated operation of expanding and pressing the sealing ring, improving assembly efficiency. After the elastic expansion claw 11 opens the sealing ring, the push assembly 6 pushes the sealing ring upward until it is pressed into the sealing groove of the bearing 7.

[0042] Furthermore, the pushing assembly 6 includes a second driving member 62 and a pushing member 61 disposed at its end, wherein the second driving member 62 is fixed to the bottom base 5.

[0043] Specifically, the modular design facilitates maintenance and replacement, and the pusher 61 can be adapted to different types of sealing rings.

[0044] Furthermore, the positioning component 8 includes a fourth driving member 81 and a sleeve 82 driven therefrom, wherein a stepped positioning sleeve 83 is provided inside the sleeve 82.

[0045] Furthermore, the stepped positioning sleeve 83 has a stepped inner hole structure, which is used to cooperate with the stepped column 9 and the bearing 7 respectively.

[0046] Specifically, the stepped positioning sleeve 83 is a three-level serial inner sleeve. The three-level serial inner sleeve structure achieves precise centering and layered limiting, avoiding skewing during installation.

[0047] Furthermore, the pushing component 61 is an electromagnet.

[0048] Specifically, during the unloading process, the electromagnet attracts and fixes the bearing 7 after installation, so that the positioning component 8 can be quickly moved away.

[0049] Furthermore, it also includes a horizontally positioned fifth drive component 12, with a push plate at its end for unloading the bearing 7 after the seal ring is installed.

[0050] Specifically, automated unloading reduces manual intervention and improves the continuous operation capability of the production line. After installation, the fifth drive component 12 pushes the push plate to send the bearing 7 into the collection tank.

[0051] Furthermore, the driving component is one of a pneumatic telescopic rod, a hydraulic cylinder, or an electric push rod.

[0052] Specifically, the driving components include a first driving component 2, a second driving component 62, a fourth driving component 81, a third driving component 10, and a fifth driving component 12.

[0053] Furthermore, the elastic expansion claw 11 consists of multiple arc-shaped elastic sheets, which are arranged around the lower end of the stepped column 9.

[0054] Specifically, the arc design ensures uniform distribution of expansion force, and the elastic material has good resilience, extending its service life. When the cone 3 is pressed down, the elastic sheet bends and expands outward; when it retracts, it automatically returns to its original shape, facilitating the next operation.

[0055] Specifically, the guide structure ensures the straightness of axial movement and repeatability of positioning, avoiding swaying.

[0056] Furthermore, a guide structure is provided between the top base 1 and the bottom base 5 to ensure the movement accuracy of the stepped column 9 and the cone 3.

[0057] Furthermore, it also includes a control system, which coordinates the sequence and stroke of the various driving components.

[0058] Specifically, by programming with a PLC or microcontroller, the timing, stroke, and speed of each driving component can be set to achieve one-button operation.

[0059] When using the equipment: Secure it to the workbench and connect the air and power sources. Check that all drive components are properly connected and that the control system is ready.

[0060] Place the small bearing 7, to be fitted with the sealing ring, into the stepped positioning sleeve 83 of the positioning assembly 8.

[0061] Place the sealing ring in the installation position above the bearing 7, start the third drive component 10, push the stepped column 9 down as a whole, so that the elastic expansion claw 11 enters the inner hole of the sealing ring.

[0062] The first driving component 2 is activated, which pushes the cone 3 to move axially downward, opening the elastic expansion claw 11 and causing the sealing ring to expand evenly.

[0063] The third drive component 10 continues to extend, smoothly pushing the expanded sealing ring into the sealing groove of the bearing 7.

[0064] After the sealing ring is installed, the electromagnet is activated, attracting the bearing. Under the action of the driving component, the cone 3 and the elastic expansion claw 11 move away in sequence. Then, the fourth driving component 81 extends to move the sleeve 82 away.

[0065] When the electromagnet is de-energized, the fifth drive component 12 is activated, pushing the push plate to push the installed bearing into the collection tank, thus completing the automated unloading.

[0066] Each drive component returns to its initial position in the preset sequence of the control system, ready for the next installation.

[0067] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
