The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] Example 1

[0039] As attached Figure 1 and attached Figure 2 As shown, the utility model discloses a bearing seal ring press-in auxiliary tooling for pressing the seal ring 53 into the bearing 5, and the utility model is only applicable to the bearing 5 whose inner ring 51 is higher than the outer ring 52. For details, please refer to the attached Figure 3 The press-in auxiliary tooling of the bearing seal ring mainly includes: a pressure-bearing device 2, a pressing device 1 and a supporting device 3. When in use, the pressure-bearing device 2 is placed on the workbench; then, the bearing 5 with the sealing ring 53 is placed vertically into the pressure-bearing cylinder 22 on the pressure-bearing device 2; then, the supporting device 3 is pressed against both sides of the outer ring 52 of the bearing 5, which can play a role in positioning the bearing 5 to a certain extent; then, the pressing device 1 is placed above the bearing 5, so that the pressing cylinder 12 on the pressing device 1 is facing the sealing ring 53 on the bearing 5; at this time, the tooling and the bearing 5 are placed as a whole directly below the working end of a press, the press is started, and the pressing device 1 is pressed down; in this process, the pressing cylinder 12 and the pressure-bearing cylinder 22 are pressed against the sealing ring 53, and the sealing ring 53 gradually fits tightly against the retaining frame, balls, inner ring 51 and outer ring 52; finally, the sealing ring 53 is accurately pressed into the bearing 5, and the retaining frame and balls of the bearing 5 are separated from the external environment, thereby protecting the internal structure of the bearing 55.

[0040] The specific structure of the press-in auxiliary tooling for the bearing seal ring is as follows: a pressure-bearing device 2 is provided on its lower side, and the pressure-bearing device 2 includes a bottom plate 21, and a pressure-bearing cylinder 22 is provided at the top of the bottom plate 21, and the top of the pressure-bearing cylinder 22 is open; a pressing device 1 is provided on the upper side of the pressure-bearing device 2, and a top plate 11 is provided on the pressing device 1, and a pressing cylinder 12 is provided at the bottom of the top plate 11, and the bottom of the pressing cylinder 12 is open, and the axial center of the pressing cylinder 12 coincides with the axial center of the pressure cylinder 22; a supporting device 3 is provided at the top of the bottom plate 21, and the supporting devices 3 are symmetrically arranged on both sides of the pressure cylinder 22. Compared with the existing technology, the utility model simplifies the corresponding structure, thereby reducing the cost.

[0041] In a specific application scenario, the outer diameter of the pressure-bearing cylinder 22 is equal to the inner diameter of the outer ring 52 of the bearing 5, and the inner diameter of the pressure-bearing cylinder 22 is equal to the outer diameter of the inner ring 51 of the bearing 5; in addition, the pressure-bearing cylinder 22 is substantially arranged at the center of the top of the bottom plate 21, and the depth of the pressure-bearing cylinder 22 is equal to the distance between the bottom end of the inner ring 51 and the sealing ring 53, and the pressure-bearing cylinder 22 is equal to the inner diameter of the outer ring 52 of the bearing 5. Figure 1The bearing 5 is suspended above the pressure-bearing cylinder 22. When the bottom end of the inner ring 51 of the bearing 5 contacts the bottom end of the inner cavity of the pressure-bearing cylinder 22, the top end of the pressure-bearing cylinder 22 will press against the sealing ring 53 located on the bottom side of the bearing 5. Under normal circumstances, the retainer in the bearing 5 is divided into an upper retainer and a lower retainer. The upper retainer is set on the upper side of the bearing 5, and the lower retainer is set on the bottom side of the bearing 5. Therefore, there are two sealing rings 53 on the bearing 5, which are set on the upper retainer and the lower retainer respectively. This design ensures the sealing of the upper and lower parts of the bearing 5 at the same time. When in use, the bearing 5 is placed vertically into the pressure-bearing cylinder 22. Due to the design of the pressure-bearing cylinder 22, the bearing 5 located inside the pressure-bearing cylinder 22 will not shake or tilt, thereby achieving the purpose of supporting the bearing 5.

[0042] In a specific application scenario, there is a pressing device 1 above the pressure-bearing device 2, and the outer diameter of the pressing cylinder 12 of the pressing device 1 is equal to the inner diameter of the outer ring 52 of the bearing 5, and the inner diameter of the pressing cylinder 12 is equal to the outer diameter of the inner ring 51 of the bearing 5; the pressing cylinder 12 is roughly arranged at the center position of the bottom end of the top plate 11, and the inner diameter of the sealing ring 53 is equal to the outer diameter of the inner ring 51 of the bearing 5, and the depth of the pressing cylinder 12 is equal to the depth of the sealing ring 53 pressed into the bearing 5. During use, the pressing device 1, placed directly below the press, is pressed. Because the axial center of the pressing cylinder 12 coincides with the axial center of the pressure cylinder 22, the pressing cylinder 12 squeezes the sealing ring 53 on the upper side of the bearing 5, while the pressure cylinder 22 squeezes the sealing ring 53 on the lower side of the bearing 5. After a period of time, the sealing ring 53 is accurately pressed into the bearing 5. The press returns to its initial position, and the user removes the pressing device 1. Then, the bearing 5 is removed from the pressure cylinder 22, thereby achieving the purpose of pressing the sealing ring 53 into the bearing 5. Due to the design of the pressing cylinder 12 and the pressure cylinder 22, the sealing ring 53 is evenly stressed, and the sealing performance of the bearing 5 can meet high requirements.

[0043] In a specific application scenario, the supporting device 3 provided on the top of the bottom plate 21 includes a connecting seat 31, a telescopic block 32, a supporting block 34 and a distance detector 33. Figure 1 and attached Figure 2As shown, the connecting seats 31 of the supporting device 3 are symmetrically arranged on both sides of the pressure-bearing cylinder 22, and the depth of the pressing cylinder 12 is less than the distance between the top plate 11 and the connecting seat 31; the telescopic block 32 is arranged on the side of the connecting seat 31 facing the pressure-bearing cylinder 22; normally, a cylinder is arranged inside the connecting seat 31, and one end of the cylinder is connected to a pipeline system, which is used to transport the high-pressure airflow required for the cylinder to work; in addition, a regulating valve is provided on the cylinder, which is used to control the flow rate of the airflow; the end of the telescopic block 32 close to the connecting seat 31 is connected to the working end of the cylinder; at the same time, the regulating valve is electrically connected to a control panel 4, which can change the parameters of the regulating valve to control the extension and contraction distance of the cylinder; a distance detector 33 is provided on the top of the telescopic block 32, which The detector 33 is located near the supporting block 34, and the distance detector 33 is electrically connected to the control panel 4; the distance detector 33 can be a distance sensor, which can transmit the real-time distance between itself and the outer ring 52 of the bearing 5 to the control panel 4, and the corresponding distance information will be displayed on the screen of the control panel 4, and the distance information will be compared with the pre-set value; of course, the user can make reasonable adjustments to the position of the distance detector 33 according to his own needs, as long as the distance detector 33 can detect the distance between the telescopic block 32 and the outer ring 52 of the bearing 5, the corresponding content will not be repeated here; the telescopic block 32 is provided with a supporting block 34 at one end close to the pressure-bearing cylinder 22, and the supporting block 34 is generally arc-shaped, and the supporting block 34 is adapted to the outer peripheral surface of the outer ring 52 of the bearing 5. When in use, the distance value between the telescopic block 32 and the outer ring 52 of the bearing 5 is set in advance on the control panel 4; then, the bearing 5 is placed vertically into the pressure cylinder 22; then, the button corresponding to the control regulating valve on the control panel 4 is pressed. At this time, the air flows into the cylinder through the pipeline system, and the working end of the cylinder extends, and the cylinder moves with the telescopic block 32 toward the outer ring 52 of the bearing 5; in this process, the distance detector 33 on the telescopic block 32 will detect the real-time distance between the telescopic block 32 and the outer ring 52 of the bearing 5 in real time, and transmit the distance information to the control panel 4 in real time, and the information will be displayed on the screen of the control panel 4 , for the user to view; at the same time, the control panel 4 compares this distance information with the preset distance value in real time; if the detected value is greater than the set distance value, the control panel 4 drives the regulating valve to continue to let in airflow, and the working end of the cylinder continues to move with the telescopic block 32 toward the outer ring 52 of the bearing 5; when the detected value is equal to the set distance value, the control panel 4 immediately drives the regulating valve to stop letting in airflow, and the working end of the cylinder stops moving. At this time, the supporting block 34 on the telescopic block 32 just rests against the outer ring 52 of the bearing 5, thereby playing a role in assisting the positioning of the bearing 5 in the pressure cylinder 22.

[0044] The above content is mainly aimed at scenarios with high sealing requirements. This embodiment also considers another scenario. For example, the bearing 5 used in industry needs to have high high temperature resistance, and the sealing of the bearing 5 only needs to meet certain requirements, that is, the sealing requirements for the bearing 5 are relatively low. The specific solution is as follows: when the outer diameter of the inner ring 51 of the bearing 5 is smaller than the inner diameter of the pressing cylinder 12 and the pressure cylinder 22, and the inner diameter of the outer ring of the bearing 5 is greater than or equal to the outer diameter of the pressing cylinder 12 and the pressure cylinder 22, the bearing 5 placed in the pressure cylinder 22 may tilt if it is not under the action of external force. When the bearing 5 is tilted, the user can manually place the bearing 5 flat on the bottom of the inner cavity of the pressure-bearing cylinder 22; at the same time, operate the control panel 4, and under the action of the above-mentioned supporting device 3, the bearing 5 is fixed in the pressure-bearing cylinder 22, and the user releases the bearing 5; then, place the pressing device 1 above the bearing 5, so that the pressing cylinder 12 of the pressing device 1 is opposite to the pressure-bearing cylinder 22, that is, the axial center of the pressing cylinder 12 coincides with the axial center of the pressure-bearing cylinder 22, as shown in the attached figure. Figure 1 As shown; then, the tooling and the bearing 5 are placed as a whole directly below the working end of a press, the press is started, and the pressing device 1 moves toward the pressure cylinder 22; in this process, part of the area of ​​the sealing ring 53 in the bearing 5 is squeezed by the pressing cylinder 12 and the pressure cylinder 22; after a period of time, the press returns to the initial position, and the user removes the pressing device 1; then, the bearing 5 is taken out of the pressure cylinder 22, and the sealing performance of the bearing 5 can meet lower requirements; at the same time, such a design can be applied to the pressing-in processing of more types of sealing rings of bearings 5, thereby expanding the scope of use or usage scenarios of the tooling to a certain extent, but the corresponding specifications or sizes of the processed bearings need to meet the requirements described in this paragraph.

[0045] The present invention also considers another specific application scenario, which is described as follows: the outer diameter of the outer ring 52 of the bearing 5 is fixed, and the outer diameter of the inner ring 51 of the bearing 5 is smaller than the inner diameter of the pressing cylinder 12 and the pressure cylinder 22, and the inner diameter of the outer ring of the bearing 5 is greater than or equal to the outer diameter of the pressing cylinder 12 and the pressure cylinder 22. The positions of the telescopic block 32 and the supporting block 34 in the supporting device 3 can remain unchanged, as long as the supporting block 34 can support the outer ring 52. In this case, the above-mentioned cylinder, piping system, control panel, regulating valve and distance detector 33 can be omitted. Therefore, the design of this section can further reduce the cost of the auxiliary tooling for pressing the bearing seal ring.

[0046] In order to control the working condition of the holding device 3, as shown in the attached Figure 1 As shown, the control panel 4 is provided on the bottom plate 21. In a specific application scenario, the control panel 4 is provided at the lower right corner of the top of the bottom plate 21; of course, the position of the control panel 4 can be appropriately adjusted according to the needs of the user, and the corresponding content is not repeated here.

[0047] Example 2

[0048] As attached Figure 1 As shown, the utility model discloses a pressing auxiliary tool for a bearing sealing ring, which is used to improve the working efficiency of the above-mentioned embodiment 1. In addition to the components in the above-mentioned embodiment 1, a positioning column 13 is also provided. The positioning column 13 can play the role of quickly assembling the pressing device 1 and the pressure-bearing device 2, thereby improving the working efficiency to a certain extent.

[0049] In a specific application scenario, a positioning column 13 is provided at the bottom end of the top plate 11 of the pressing device 1. Figure 1 As shown, positioning columns 13 are symmetrically provided on the front and rear sides of the bottom end of the top plate 11, and two positioning holes matching the positioning columns 13 are opened at the top of the bottom plate 21 of the pressure-bearing device 2. The depth of the positioning hole is equal to the depth of the pressing cylinder 12 in the pressing device 1, and the outer diameter of the positioning column 13 is equal to the inner diameter of the positioning hole; in addition, the distance between the positioning column 13 and the pressing cylinder 12 is equal to the distance between the positioning hole and the pressure-bearing cylinder 22; of course, the user can make corresponding adjustments to the position and number of the positioning columns 13 according to his own needs. At the same time, corresponding positioning holes need to be opened on the bottom plate 21. The specific content will not be repeated here. After placing the bearing 5 into the pressure-bearing cylinder 22, the user inserts all the positioning posts 13 on the pressing device 1 into all the positioning holes on the pressure-bearing device 2. At this time, the pressing cylinder 12 must be opposite to the pressure-bearing cylinder 22, that is, the axial center of the pressing cylinder 12 coincides with the axial center of the pressure-bearing cylinder 22. This design can quickly assemble the tooling; in addition, if the positioning post 13 is not provided and the pressing cylinder 12 is not provided at the exact center of the top plate 11, when the pressing device 1 is placed on the bearing 5, the side of the pressing device 1 close to the pressing cylinder 12 will be heavier and the side away from the pressing cylinder 12 will be lighter, and the lighter side may tilt toward the heavier side; however, after providing the positioning post 13 and the positioning hole, even if the pressing cylinder 12 is not provided at the exact center of the top plate 11, as long as the positioning post 13 is inserted into the positioning hole, the pressing cylinder 12 will not tilt, thereby improving the working efficiency of the bearing seal ring pressing auxiliary tooling to a certain extent.
