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

[0031] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example 1: See Figure 1-Figure 4 The present invention provides a technical solution: a bearing pressing device for an automobile bearing seat, comprising a supporting mechanism 1, the supporting mechanism 1 comprising a fixing frame 101, the outer wall of the fixing frame 101 is fixedly connected with a supporting foot 102, the inner wall of the fixing frame 101 is fixedly connected with a dual-axis motor 103, the output end of the dual-axis motor 103 is fixedly connected with a rotating shaft 104, the outer wall of one side of the fixing frame 101 close to the dual-axis motor 103 is fixedly connected with a first motor 105, and the bottom outer wall of the fixing frame 101 is fixedly connected with a connecting rod 1 08, a curved rod 106 is fixedly connected to one side of the bottom of the fixing frame 101 near the connecting rod 108, a first through hole 107 is opened on the inner wall of the curved rod 106, a connecting frame 109 is fixedly connected to the outer wall of the fixing frame 101, a first hydraulic rod 110 is fixedly connected to the inner wall of one end of the connecting frame 109 away from the fixing frame 101, an auxiliary mechanism 2 is arranged at the output end of the first hydraulic rod 110, a second through hole 111 is opened on the inner wall of one side of the connecting frame 109 near the first hydraulic rod 110, and further comprises:

[0034] The adjusting mechanism 3 includes an adjusting plate 301 fixedly connected to the output end of the first motor 105, a laser emitter 304 is fixedly connected to the top outer wall of the adjusting plate 301, an auxiliary wheel 307 is rotatably connected to the bottom outer wall of the adjusting plate 301 through a rotating shaft, a third hydraulic rod 302 is fixedly connected to the inner wall of the adjusting plate 301, an output end of the third hydraulic rod 302 passes through the adjusting plate 301 and is fixedly connected to the first pressing plate 303, a clamping mechanism 4 is provided on both sides of the first pressing plate 303, the first motor 105 is used to adjust the inclination angle of the adjusting plate 301, and the first through hole 107 is used to limit the adjusting plate 301 When the position adjustment operation of the automobile bearing seat is performed, the third hydraulic rod 302 starts to work, and it applies a thrust to the automobile bearing seat through the first pressure plate 303, so that the automobile bearing seat moves toward the central area of ​​the adjustment plate 301. At the same time, the first motor 105 is started to adjust and control the rotation angle of the adjustment plate 301. During the rotation of the adjustment plate 301, it rolls on the inner wall of the first through hole 107 with the help of the auxiliary wheel 307. This rolling method can effectively disperse the friction and unstable force generated when the adjustment plate 301 rotates, thereby ensuring that the adjustment plate 301 remains stable during the angle adjustment process.

[0035] The auxiliary mechanism 2 includes a first sliding frame 201 fixedly connected to the output end of the first hydraulic rod 110, a third through hole 202 is opened on the outer surface of the first sliding frame 201, and a laser receiver 208 is fixedly connected to the bottom inner wall of the first sliding frame 201. When the automobile bearing is installed, the first motor 105 starts to operate and drives the adjustment plate 301 to adjust the rotation angle. As the angle of the adjustment plate 301 changes, the laser receiver 208 can receive the laser emitted by the laser transmitter 304, and use this as a basis to accurately determine whether the automobile bearing seat and the automobile bearing are in the same center line position. The first hydraulic rod 110 starts and pushes the first sliding frame 201 to move toward the automobile bearing seat. With the help of the pushing effect of the first sliding frame 201, the automobile bearing is driven to move to one side of the automobile bearing seat to complete the installation of the automobile bearing, ensuring that the automobile bearing and the automobile bearing seat can be accurately docked and installed in place.

[0036] The top outer wall of the first sliding frame 201 is fixedly connected with the second hydraulic rod 203, the output end of the second hydraulic rod 203 is fixedly connected with the first sliding block 204, the inner wall of the first sliding block 204 is rotatably connected with the rotating rod 205 through the rotating shaft, the second sliding block 206 is slidably connected to the inner wall of the third through hole 202, and the outer wall of the second sliding block 206 away from the rotating rod 205 is fixedly connected with the force plate 207. When performing the automobile bearing clamping task, the second hydraulic rod 203 starts to run and generates a pulling force to act on the first sliding block 204, and the pulling force causes the first sliding block 204 to move toward the position where the first sliding frame 201 is located. During the displacement process of the first sliding block 204, the second sliding block 206 is driven to slide in the third through hole 202 by the transmission of the rotating rod 205. Because the force plate 207 and the second sliding block 206 are connected to each other, when the second sliding block 206 slides, the force plate 207 moves synchronously and contacts with automobile bearings of different diameters, thereby applying a squeezing force to them.

[0037] Example 2: Please refer to Figure 5-Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: a first fixed shaft 305 is fixedly connected to the bottom outer wall of the adjustment plate 301, an end of the first fixed shaft 305 away from the adjustment plate 301 passes through the connecting rod 108 and is fixedly connected to a first spring 306, and an end of the first spring 306 close to the adjustment plate 301 is fixedly connected to the connecting rod 108. When the first motor 105 adjusts the angle of the adjustment plate 301, the adjustment plate 301 slides on the inner wall of the connecting rod 108 through the first fixed shaft 305, and the vibration of the adjustment plate 301 during the adjustment process is absorbed by the first spring 306, thereby ensuring the stability of the adjustment plate 301 during the adjustment process.

[0038] The clamping mechanism 4 includes a second sliding frame 401 slidably connected to the rotating shaft 104, and a fixed plate 402 is fixedly connected to the top outer wall of the second sliding frame 401. When the adjustment operation of the automobile bearing seat is started, the dual-axis motor 103 starts to operate, and drives the second sliding frame 401 to move toward the direction of the automobile bearing seat through the rotating shaft 104. As the second sliding frame 401 moves, the fixed plate 402 thereon gradually approaches the two ends of the automobile bearing seat. The fixed plate 402 clamps the automobile bearing seat by virtue of the contact pressure with the automobile bearing seat, and adjusts the position of the automobile bearing seat so that the automobile bearing seat can be accurately on the same center line as the automobile bearing.

[0039] The outer wall of the second sliding frame 401 is fixedly connected to a second motor 403, the output end of the second motor 403 runs through the second sliding frame 401 and is fixedly connected to a rotating frame 404, the second motor 403 is used to drive the rotating frame 404 to flip toward one side of the automobile bearing seat, the rotating frame 404 is used to clamp the two ends of the automobile bearing seat, and a second pressing plate 405 is provided on the outer wall of the end of the rotating frame 404 away from the second motor 403, and a second fixed shaft 406 is fixedly connected to the outer wall of the second pressing plate 405 on the side close to the rotating frame 404. One end away from the second pressure plate 405 penetrates the rotating frame 404 and is fixedly connected with the second spring 407. One end of the second spring 407 close to the second pressure plate 405 is fixedly connected with the rotating frame 404. After the automobile bearing seat is moved to a position on the same center line as the automobile bearing, the second motor 403 starts to work, and the second motor 403 drives the rotating frame 404 to rotate, and the second pressure plate 405 on the outer wall of the rotating frame 404 moves accordingly. The second pressure plate 405 applies pressure to the two ends of the automobile bearing seat, thereby tightly clamping and fixing the automobile bearing seat.
