DETAILED DESCRIPTION

[0021] The core of the present invention is to provide a bearing auxiliary installation device, so that the installation of the bearing can be completed by one person, thereby improving the installation efficiency.

[0022] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0023] like Figure 1 and Figure 2 As shown, the bearing auxiliary installation device disclosed in the embodiment of the present invention comprises a workbench 1, a rotating shaft positioning table 2, a clamping assembly 3 and a bearing clamping assembly 9. Among them, the workbench 1 is a supporting component of the bearing auxiliary installation device, which is used to realize the installation of other components.

[0024] The shaft positioning platform 2 is disposed on the workbench 1 and has a positioning groove for positioning the shaft 4. The positioning groove only needs to be able to prevent the shaft 4 from rolling on the shaft positioning platform 2, and the axial movement of the shaft 4 can be limited by the clamping assembly 3.

[0025] The clamping assembly 3 is arranged on the rotating shaft positioning platform 2, and is used to clamp the rotating shaft 4 to limit the sliding of the rotating shaft 4 in the positioning groove along the axial direction, so that the rotating shaft 4 can remain motionless when the bearing 5 is pushed onto the rotating shaft 4. The bearing clamping assembly 9 is slidably arranged on the workbench 1, and is arranged relative to the rotating shaft positioning platform 2 to move in the direction close to and away from the rotating shaft positioning platform 2. The bearing clamping assembly 9 is used to clamp the bearing 5. During installation, the bearing 5 is first clamped on the bearing clamping assembly 9, and then the bearing clamping assembly 9 is pushed to move in the direction close to the rotating shaft positioning platform 2 until the bearing 5 is inserted into the rotating shaft 4.

[0026] It should be noted that when installing the bearing 5, the bearing 5 also needs to be heated so that the bearing 5 expands due to the heat, so as to facilitate sleeve installation on the rotating shaft 4. In addition, the rotating shaft 4 is not limited to the rotating shaft of the motor, but can also be a rotating shaft used in other equipment. As long as the shaft needs to be installed with a bearing, it can be assisted by the bearing auxiliary installation device disclosed in the embodiment of the present invention.

[0027] The bearing auxiliary installation device provided by the present invention has a rotating shaft positioning platform 2 arranged on a workbench 1, and the rotating shaft 4 can be supported by the rotating shaft positioning platform 2. The rotating shaft 4 supported on the rotating shaft positioning platform 2 can be clamped by the clamping assembly 3 on the workbench 1 to prevent the rotating shaft 4 from moving on the rotating shaft positioning platform 2. The clamping assembly 3 can replace the personnel to fix the rotating shaft placed in the positioning groove of the rotating shaft positioning platform 2, thereby reducing the labor intensity of the operator. The bearing clamping assembly 9 on the workbench 1 can be used to clamp the bearing 5, and the bearing clamping assembly 9 is slidably matched on the workbench 1. By pushing the bearing clamping assembly 9 to slide, the bearing 5 clamped on the bearing clamping assembly 9 can be pushed into the rotating shaft 4 to realize the installation of the bearing 5. The bearing 5 can also be disassembled by the reverse sliding of the bearing clamping assembly 9, so that a single person can complete the entire installation and disassembly process, effectively improving the work efficiency.

[0028] By using the bearing auxiliary installation device disclosed in this embodiment, the rotating shaft 4 and the bearing 5 can be conveniently fixed, reducing the installation time. Moreover, since the positions of the rotating shaft 4 and the bearing 5 are constrained, when installing, it is only necessary to push the bearing clamping assembly 9 to move, so the installation experience is not required to be high, and it is easier to ensure the installation accuracy, avoiding the problems of increased noise and vibration during the operation of the motor due to insufficient installation accuracy. It is easier to achieve installation standardization and ensure the consistency of each installation.

[0029] like Figure 3 and Figure 4As shown, in this embodiment, the clamping assembly 3 may include a lifting slider 304, a swing rod 306 and a driving assembly. Among them, the rotating shaft positioning platform 2 is provided with a lifting slide groove, and the lifting slider 304 is slidably arranged in the lifting slide groove, so that the lifting slider 304 can only perform lifting actions along the lifting slide groove, and the lifting slide groove is equivalent to a guide structure for the reciprocating motion of the lifting slider 304.

[0030] There are two swing rods 306, which are symmetrically arranged on both sides of the lifting slider 304 and rotatably connected to the rotating shaft positioning platform 2. The first end of the swing rod 306 abuts against the lifting slider 304, and is subjected to the lifting action of the lifting slider 304. The swing rod 306 swings back and forth, so that the second ends of the two swing rods 306 move closer to and away from each other to clamp and release the rotating shaft 4. In this embodiment, the swing rod 306 is moved to swing by the lifting action of the lifting slider 304. Since the two swing rods 306 are respectively located on both sides of the lifting slider 304, when the two swing rods 306 swing, the second ends of the two swing rods 306 move closer to or away from each other. When they are closer to each other, the rotating shaft 4 located between the two swing rods 306 can be clamped; when they are away from each other, the rotating shaft 4 can be released.

[0031] It should be noted that, in order to provide the two swinging rods 306 with a swinging degree of freedom, the rotating shaft positioning platform 2 should have a swinging groove capable of accommodating the swinging rods 306, and the swinging groove can ensure that the swinging rods 306 will not interfere with the rotating shaft positioning platform 2 when swinging back and forth between the extreme positions. Since there are two swinging rods 306, the swinging grooves should also be symmetrically arranged on both sides of the positioning groove of the rotating shaft positioning platform 2. Before the rotating shaft 4 is placed in the positioning groove, the swinging rods 306 should be driven to an open state away from each other to ensure that the rotating shaft 4 can be placed in the positioning groove.

[0032] The driving assembly is used to drive the lifting slider 304 to perform a lifting motion along the lifting slot. The present embodiment does not limit the specific structure of the driving device, as long as it can drive the lifting slider 304 to perform a lifting motion along the lifting slot.

[0033] Furthermore, a first positioning wheel 305 for abutting against the lower part of the rotating shaft 4 is provided on the top of the lifting slider 304. When the lifting slider 304 rises, the first positioning wheel 305 can abut against the lower part of the rotating shaft 4. When the lifting slider 304 descends, the first positioning wheel 305 can be out of contact with the rotating shaft 4.

[0034] The second end of the swing rod 306 is provided with a second positioning wheel 307 for abutting against the side of the rotating shaft 4. As the lifting slider 304 rises, the swing rod 306 swings, and the second positioning wheel 307 gradually approaches the side of the rotating shaft 4 until it abuts against the side of the rotating shaft 4. In this way, the bottom and two sides of the rotating shaft 4 have three abutment points (the first positioning wheel 305 and the two second positioning wheels 307). It should be noted that the axes of the first positioning wheel 305 and the second positioning wheel 307 can be parallel to the axis of the rotating shaft 4 to avoid the first positioning wheel 305 and the second positioning wheel 307 from rubbing against each other when they contact the rotating shaft 4 and scratching the rotating shaft 4.

[0035] The first end of the swing rod 306 is provided with a roller 308. The side wall of the lifting slider 304 is an inclined surface with acute angles to both the vertical direction and the horizontal direction. The roller 308 abuts against the side wall of the lifting slider 304. The distance between the two side walls of the lifting slider 304 gradually increases from top to bottom. The first end of the swing rod 306 contacts the side wall of the lifting slider 304 through the roller 308, which can reduce the friction between the two, making it easier for the lifting slider 304 to push the swing rod 306 to swing.

[0036] In a specific embodiment of the present invention, the first ends of the two swinging rods 306 are connected by a reset elastic member 309, and the reset elastic member 309 is used to pull the first ends of the two swinging rods 306 to fit the lifting slider 304. That is, under the elastic force of the reset elastic member 309, the first ends of the swinging rods 306 are always in contact with the side wall of the lifting slider 304, that is, when the roller 308 is provided at the first end of the swinging rod 306, the roller 308 is always in contact with the side wall of the lifting slider 304 and is not affected by the lifting action of the lifting slider 304.

[0037] In a specific embodiment of the present invention, the driving assembly may include a push block 303 and a piston cylinder 301. A push slot slidably matched with the push block 303 should be provided on the rotating shaft positioning platform 2, so that the push block 303 moves in a predetermined direction.

[0038] The bottom wall of the lifting slider 304 is an inclined surface, and the push block 303 cooperates with the bottom wall of the lifting slider 304. As the push block 303 contacts the lifting slider 304 at different positions, the height of the lifting slider 304 is different. The piston cylinder 301 is used to push the push block 303 to reciprocate, so as to drive the lifting slider 304 to perform a lifting action. The piston cylinder 301 can be a hydraulic cylinder or a pneumatic cylinder. The piston rod of the piston cylinder 301 pushes the push block 303 to reciprocate, thereby controlling the lifting slider 304 to perform a lifting action.

[0039] In order to ensure that the clamping assembly 3 has a better clamping force on the rotating shaft 4, a plurality of lifting sliders 304 can be provided, and each lifting slider 304 is correspondingly provided with a swing rod 306 and a push block 303. Taking two lifting sliders 304 arranged in parallel as an example, the two lifting sliders 304 are correspondingly provided with a swing rod 306 and a push block 303.

[0040] The push blocks 303 corresponding to the two lifting sliders 304 are connected through a linkage rod 302, and the output end of the piston cylinder 301 is connected to the linkage rod 302. The linkage rod 302 applies the push and pull force output by the piston cylinder 301 to each push block 303 to drive each push block 303 to move synchronously, thereby controlling each lifting slider 304 to rise and fall synchronously, and each swing rod 306 to swing synchronously.

[0041] like Figure 1 As shown, the bearing clamping assembly 9 is slidably arranged on the workbench 1 through the support assembly, and the support assembly includes a sliding plate 7 and a mounting block 8 arranged on the sliding plate 7. The sliding plate 7 and the mounting block 8 can be provided with a support column according to the height of the rotating shaft 4 to increase the height of the mounting block 8. The support column can be a support column with a fixed height, or a lifting column with a lifting function to adjust the height of the mounting block 8, thereby meeting the requirements of the rotating shaft 4 of various diameters, so that the bearing 5 and the rotating shaft 4 remain coaxial.

[0042] The bearing clamping assembly 9 is arranged on the mounting block 8, and the workbench 1 is provided with a guide portion 6 that slidably cooperates with the sliding plate 7. The guide portion 6 can be a slide rail or a slide groove, and a structure that cooperates with the guide portion 6 needs to be provided on the sliding plate 7. For example, when the guide portion 6 is a slide rail, a slide groove that cooperates with the slide rail should be provided on the sliding plate 7; when the guide portion 6 is a slide groove, a slide rail that cooperates with the slide rail should be provided on the sliding plate 7 to facilitate the reciprocating sliding of the sliding plate 7.

[0043] like Figure 5 As shown, in this embodiment, the bearing clamping assembly 9 includes a fixed plate 901, a screw 906, a drive motor 905, a movable plate 907 and a clamping arm 904. The fixed plate 901 is arranged on the mounting block 8, and the fixed plate 901 mainly serves as a mounting base for other components of the bearing clamping assembly 9.

[0044] The screw rod 906 is rotatably disposed on the fixed disk 901, and the fixed disk 901 can support the screw rod 906; the driving motor 905 is disposed on the fixed disk 901 and is drivingly connected to the screw rod 906. It should be noted that the driving motor 905 can be embedded in the mounting block 8.

[0045] The movable plate 907 is threadedly matched with the screw rod 906, and the driving motor 905 drives the screw rod 906 to rotate. Since the movable plate 907 is threadedly matched with the screw rod 906, the movable plate 907 moves along the axial direction of the screw rod 906, and the moving direction is related to the rotation direction of the screw rod 906. The moving direction of the movable plate 907 can be controlled by controlling the rotation direction of the screw rod 906.

[0046] There are at least two clamping arms 904, and in this embodiment, there are four clamping arms 904. Of course, the clamping arms 904 can also be designed to be other numbers, as long as they are more than two. Each clamping arm 904 is used to clamp the bearing 5, and is evenly arranged around the fixed disk 901. The clamping arm 904 is hinged to the fixed disk 901 through the first connecting rod 903, and is hinged to the movable plate 907 through the second connecting rod 908. When the movable plate 907 moves along the axial direction of the screw rod 906, it can pull the clamping arm 904 to swing through the second connecting rod 908, thereby causing each clamping arm 904 to fold and open. When each clamping arm 904 is folded, it can clamp the bearing 5; when each clamping arm 904 is opened, it can release the bearing 5.

[0047] Further, the fixed disk 901 and the movable plate 907 may both be circular disks and coaxially arranged, and the diameter of the movable plate 907 is smaller than the diameter of the fixed disk 901. It should be noted that the fixed disk 901 and the movable plate 907 may also be plates of other shapes, not limited to circular.

[0048] In order to enable the clamping arm 904 to better clamp the bearing 5 , the clamping arm 904 may be provided with a groove matching the bearing 5 , and the groove is used to lock the bearing 5 to prevent the bearing 5 from moving axially, thereby ensuring the clamping stability of the clamping arm 904 .

[0049] A limit plate may be provided at one end of the screw rod 906 away from the driving motor 905 to form a limit for the movable plate 907 to prevent the movable plate 907 from being separated from the screw rod 906. The fixed disk 901 may be provided with a mounting portion 902, and the first connecting rod 903 is hinged to the fixed disk 901 through the mounting portion 902. One end of the first connecting rod 903 is hinged to the clamping arm 904, and the other end is hinged to the mounting portion 902. In this embodiment, by providing the mounting portion 902, the first connecting rod 903 can be hinged to the outside of the fixed disk 901, which makes it easier to maintain the angle of the clamping arm 904, so that the clamping arm 904 maintains a better clamping angle and improves the clamping effect. It should be noted that the first connecting rod 903 may also be directly hinged to the fixed disk 901. There may be multiple first connecting rods 903, that is, each clamping arm 904 is connected to multiple first connecting rods 903.

[0050] like Figure 2 and Figure 6As shown, in a specific embodiment of the present invention, the bearing auxiliary installation device may further include a discharge assembly 11, and the discharge assembly 11 includes a horizontal moving platform 1101, a lifting moving platform 1102 and an electric clamp 1103.

[0051] The horizontal moving platform 1101 may be arranged on the workbench 1 or not, and may be arranged on one side of the workbench 1. The lifting moving platform 1102 is arranged at the output end of the horizontal moving platform 1101, and the horizontal moving platform 1101 can drive the lifting moving platform 1102 to move in the direction of approaching and moving away from the rotating shaft positioning platform 2.

[0052] The electric clamp 1103 is arranged at the output end of the lifting and moving platform 1102, and the lifting and moving platform 1102 can drive the electric clamp 1103 to perform lifting and lowering actions. The horizontal moving platform 1101 and the lifting and moving platform 1102 can be linear modules commonly used in the prior art, or other mechanisms capable of outputting linear displacement. An avoidance groove 10 is provided on the top of the rotating shaft positioning platform 2, and the electric clamp 1103 is located inside the avoidance groove 10, so that the electric clamp 1103 can clamp the rotating shaft 4 located in the positioning groove.

[0053] The working principle of the bearing auxiliary installation device disclosed in the embodiment of the present invention is as follows: When in use, the rotating shaft 4 is placed in the positioning groove on the top of the rotating shaft positioning platform 2, and the end where the bearing 5 needs to be installed is exposed outside the rotating shaft positioning platform 2, and then the piston cylinder 301 is started to operate, and the linkage rod 302 is pushed to drive the two pushing blocks 303 to move horizontally. During the movement of the pushing block 303, it cooperates with the different positions of the inclined surface at the bottom of the lifting slider 304. Under the action of the wedge structure, the lifting slider 304 is pushed to move upward, and the first positioning wheel 305 is driven to move upward to contact the bottom of the rotating shaft 4. In the process of the lifting slider 304 moving upward, the rollers 308 at both ends can be pushed, so that the swing rod 306 swings, and the second positioning wheel 307 is driven to move toward the direction of the rotating shaft 4, and finally the two second positioning wheels 307 are driven to fit the two sides of the rotating shaft 4 to fix the rotating shaft 4, thereby replacing the method of manual fixing by personnel in the prior art.

[0054] In order to limit the lifting position of the lifting slider 304, a corresponding position switch can be provided to prevent the lifting slider 304 from exceeding the limit position and thereby causing damage to the rotating shaft 4 or failing to clamp the rotating shaft 4.

[0055] After the shaft 4 is fixed, the bearing 5 is placed between the clamping arms 904, and then the driving motor 905 is started to operate, driving the screw 906 to rotate, and at the same time driving the movable plate 907 to move along the axial direction of the screw 906, so that the movable plate 907 moves toward the fixed plate 901, and drives the second connecting rod 908 to move, so that one end of the second connecting rod 908 pulls the clamping arm 904, and cooperates with the first connecting rod 903 to drive each clamping arm 904 to move toward the bearing 5 at the same time, and clamp the bearing 5 to fix it. After fixation, the sliding plate 7 is moved toward the direction of the shaft positioning platform 2 through the guide part 6, thereby driving the bearing 5 to move toward the shaft 4, and then the bearing 5 can be pushed into the shaft 4 to complete the installation of the bearing 5, and when the sliding plate 7 moves in the opposite direction, the bearing 5 can be disassembled, and the entire installation and disassembly process can be completed by one person.

[0056] After the bearing is installed, the piston cylinder 301 drives the push block 303 to reset, so that the lifting slider 304 can be reset, and the two swing rods 306 are reset under the action of the reset elastic member 309, and the restriction on the rotating shaft 4 is released. Then, the electric clamp 1103 is driven to move horizontally through the horizontal moving platform 1101, so that the clamping claws of the electric clamp 1103 move to the upper and lower sides of the rotating shaft 4, and then the rotating shaft 4 is grabbed by the electric clamp 1103. After grabbing, the electric clamp 1103 and the rotating shaft 4 can be driven to move upward through the lifting moving platform 1102, and the rotating shaft 4 is moved to the top of the rotating shaft positioning platform 2, which is convenient for personnel to take.
