Description

Technical Field

[0001] The present application relates to the field of bearing assembly tools, and in particular to a motor bearing assembly tool. Background Art

[0002] The motor is mainly composed of a stator, a rotor, an output shaft and a casing, and bearings need to be installed on the output shaft to ensure stable rotation of the output shaft.

[0003] Currently, bearings are typically manually press-fitted onto the output shaft. To provide support, the shaft is typically placed against a workbench to press the bearing into the desired position. However, this method only allows for the installation of bearings on one side at a time. Installing bearings on the other side of the motor requires the operator to reposition themselves or the motor, resulting in inconvenience and low efficiency. This method warrants improvement. Utility Model Content

[0004] In order to improve the problem of being unable to simultaneously install bearings on the output shafts on both sides of the motor, resulting in low work efficiency, the present application provides a motor bearing assembly tool.

[0005] The motor bearing assembly tool provided in this application adopts the following technical solution:

[0006] A motor bearing assembly tool includes a workbench, a mounting seat fixed on the workbench, the mounting seat is used to support a rotor, the workbench is connected to two movable seats via a drive assembly, the drive assembly is used to drive the two movable seats towards or away from each other, the mounting seat is located between the two movable seats, and the movable seat is provided with a receiving seat for receiving the output shaft of the rotor.

[0007] By adopting the above technical solution, when in use, first, bearings are sleeved on the output shafts on both sides of the rotor, then the rotor is placed on the mounting seat, and the output shafts on both sides of the rotor are inserted into the corresponding receiving seats, with the bearings located between the rotor and the receiving seats. Subsequently, the drive assembly is started, driving the movable seat to drive the receiving seat to move toward the mounting seat, so that the receiving seat pushes the bearings toward the rotor until the bearings are pressed into the set position. During this process, because the drive assembly is connected to the two movable seats, that is, when the drive assembly is started, it will drive the two movable seats to move synchronously the same distance, thereby achieving the simultaneous installation of the bearings on the output ends of both sides of the rotor, convenient operation, and improved work efficiency.

[0008] Optionally, the driving assembly includes a driving rod and a driving motor, the driving rod passes through the mounting seat and is rotatably connected to the mounting seat, both ends of the driving rod are provided with threaded structures with opposite rotation directions, the two movable seats are respectively sleeved on the two ends of the driving rod and are threadedly connected to the driving rod, the driving rod rotates to drive the two movable seats closer to or away from each other, the driving motor is arranged on the workbench, the output end of the driving motor is coaxially fixed with one end of the driving rod, and is used to drive the driving rod to rotate about the central axis of the driving rod.

[0009] By adopting the above technical solution, the drive motor is started to drive the drive rod to rotate. Since the moving seat is threadedly connected to the drive rod, the moving seat is restricted by the workbench and cannot rotate along with the rotation of the drive rod, so that the moving seat moves on the workbench along the length direction of the drive rod. The threads at both ends of the drive rod rotate in opposite directions, so that the moving directions of the two moving seats are opposite, so that the two moving seats can simultaneously push the bearings toward the rotor by the same distance, completing the installation of the bearings on the two output shafts of the rotor and improving work efficiency.

[0010] Optionally, a slide is fixed on the workbench, and the slide is arranged along the length direction of the driving rod. The movable seat is placed on the slide and can move on the slide.

[0011] By adopting the above technical solution, when the driving rod drives the moving seat to move, the moving seat moves on the slide, and the slide plays a role of limiting and guiding, so that the moving seat will not stumble during the movement process, thereby increasing the stability of the movement of the moving seat.

[0012] Optionally, a buffer rod is provided on the movable seat, the buffer rod is parallel to the driving rod, and the buffer rod can move along the length direction of the driving rod on the movable seat, one end of the buffer rod can abut against the rotor, and a buffer spring is provided on the buffer rod, and the spring is located on the side of the movable seat close to the mounting seat.

[0013] By adopting the above technical solution, when the moving seat drives the receiving seat to push the bearing toward the rotor, the moving seat will also move in the same direction with the buffer rod, and the buffer rod protrudes from the side of the moving seat close to the rotor under the action of the buffer spring. Therefore, during the movement, the buffer rod will first abut against the rotor. At this time, the moving seat continues to move, so that the buffer spring is compressed by the extrusion force, thereby playing a buffering role, so that the moving seat will not directly collide with the rotor, making the rotor less likely to be damaged.

[0014] Optionally, a pressure plate is fixed to one end of the buffer rod close to the mounting seat, and the pressure plate abuts against the rotor.

[0015] By adopting the above technical solution, when the receiving seat presses the bearing toward the rotor, the bearing will eventually be pressed against the pressure plate. The pressure plate plays a supporting role, so that there is a force surface for pressing the bearing, and there is no need to use the rotor as a force surface, so that the rotor is not easily damaged by pressure, thereby extending the service life of the rotating shaft.

[0016] Optionally, a placement rod is fixed on the mounting seat, the placement rod is vertically arranged, and the bottom end of the placement rod is fixed to the mounting block.

[0017] By adopting the above technical solution, the bearing to be installed is pre-mounted on the placement rod. During installation, the bearing can be directly taken from the placement rod, which is convenient to operate and improves work efficiency.

[0018] Optionally, the mounting seat is provided with two oppositely arranged support plates, which are symmetrically arranged with the central axis of the receiving seat as the axis. One end of the support plate close to the central axis of the receiving seat is hinged to the mounting seat, and the other end is tilted upward, and the rotor can be placed on the two support plates.

[0019] By adopting the above technical solution, when the size of the rotor is large, the side wall of the rotor will contact the support plate. The larger the rotor, the heavier the weight. At this time, the support plate plays a supporting role, sharing the supporting force of the rotor output shaft to prevent the output end of the rotor from bending and breaking, thereby extending the service life of the output shaft.

[0020] Optionally, a screw rod is vertically inserted into the mounting seat, the screw rod is rotatably connected to the mounting seat, and the top end of the screw rod abuts against the bottom wall of the support plate.

[0021] By adopting the above technical solution, the screw is rotated to move up and down, and the support plate is overlapped on the top of the screw under the action of gravity, so that the inclination angle of the support plate changes, which can support rotors of different sizes and has better applicability.

[0022] In summary, this application has at least one of the following beneficial effects:

[0023] 1. When in use, first install bearings on the output shafts on both sides of the rotor, then place the rotor on the mounting seat, and at the same time, insert the output shafts on both sides of the rotor into the corresponding receiving seats, with the bearings located between the rotor and the receiving seats. Then start the drive assembly, drive the movable seat to drive the receiving seat to move toward the mounting seat, so that the receiving seat pushes the bearings toward the rotor until the bearings are pressed into the set position. During this process, because the drive assembly is connected to the two movable seats, that is, when the drive assembly is started, it will drive the two movable seats to move synchronously the same distance, thereby completing the installation of the bearings on the output ends of both sides of the rotor at the same time, which is convenient to operate and improves work efficiency.

[0024] 2. Start the drive motor to drive the drive rod to rotate. Since the moving seat is threadedly connected to the drive rod, and the moving seat is restricted by the workbench, it cannot rotate along with the rotation of the drive rod, so that the moving seat moves on the workbench along the length direction of the drive rod. The threads at both ends of the drive rod rotate in opposite directions, so that the two moving seats move in opposite directions, so that the two moving seats can simultaneously push the bearing toward the rotor by the same distance, completing the installation of the bearings on the two output shafts of the rotor and improving work efficiency.

[0027] The following is combined with Figure 1 This application is described in further detail.

[0028] The embodiment of the present application discloses a motor bearing assembly tool. Figure 1 The motor bearing assembly tooling includes a horizontally positioned workbench 10, to which a mounting base 20 is fixed. A drive assembly 30 is connected to the mounting base 20. The drive assembly 30 includes a drive rod 31 and a drive motor 32. The drive rod 31 is horizontally positioned and passes through the mounting base 20. The drive rod 31 is capable of rotating on the mounting base 20. Both ends of the drive rod 31 are provided with threaded structures with opposite rotation directions, i.e., the drive rod 31 is a bidirectional screw. The drive motor 32 is mounted on the workbench 10. The output end of the drive motor 32 is coaxially fixed to one end of the drive rod 31, and is used to drive the drive rod 31 to rotate about the central axis of the drive rod 31.

[0029] Reference Figure 1 , a moving seat 40 is respectively sleeved on both ends of the driving rod 31, the moving seat 40 is located on both sides of the mounting seat 20, and the distance between the two moving seats 40 and the mounting seat 20 is equal. The driving seat is threadedly connected to the driving rod 31, and a slide 11 is fixed on the workbench 10. The slide 11 is arranged along the length direction of the driving rod 31. The slide 11 is embedded in the bottom of the moving seat 40. When the driving motor 32 is started, the driving rod 31 is driven to rotate, driving the two moving seats 40 on the slide 11 along the length direction of the driving rod 31 to approach or move away from each other.

[0030] Reference Figure 1A receiving seat 41 is fixed on the movable seat 40. When in use, bearings are first installed on the output shafts on both sides of the rotor. Then the rotor is placed on the mounting seat 20. At the same time, the output shafts on both sides of the rotor are inserted into the corresponding receiving seats 41, and the bearings are located between the rotor and the receiving seats 41. Then, the drive motor 32 is started to drive the movable seat 40 to drive the receiving seat 41 to move toward the mounting seat 20, so that the receiving seat 41 pushes the bearings toward the rotor until the bearings are pressed into the set position. During this process, because the drive rod 31 is connected to the two movable seats 40, that is, when the drive rod 31 rotates, it will drive the two movable seats 40 to move synchronously the same distance, thereby achieving the simultaneous installation of the bearings on the output ends of both sides of the rotor, convenient operation, and improved work efficiency.

[0031] Reference Figure 1 To prevent the receiving seat 41 from pushing the bearing against the rotor, which would directly collide with the rotor and apply pressure to the rotor that could damage it, a buffer rod 50 is provided on the movable seat 40. The buffer rod 50 is arranged horizontally and extends along the length of the drive rod 31. The buffer rod 50 can move along the length of the drive rod 31 on the movable seat 40. A pressure plate 52 is fixed to the end of the buffer rod 50 near the rotating seat. The pressure plate 52 can abut the rotor. A buffer spring 51 is sleeved on the buffer rod 50 and is located on the side of the movable seat 40 near the mounting seat 20.

[0032] When the moving seat 40 drives the receiving seat 41 to push the bearing toward the rotor, the moving seat 40 will also move in the same direction with the buffer rod 50, and the buffer rod 50 protrudes from the side of the moving seat 40 close to the rotor under the action of the buffer spring 51. Therefore, during the movement, the buffer rod 50 will first abut against the rotor. At this time, the moving seat 40 continues to move, so that the buffer spring 51 is compressed by the extrusion force, thereby playing a buffering role, so that the moving seat 40 will not directly collide with the rotor, making the rotor less likely to be damaged.

[0033] At the same time, the receiving seat 41 presses the bearing toward the rotor, and eventually the bearing will be pressed onto the pressure plate 52. The pressure plate 52 plays a supporting role, so that there is a force surface for pressing the bearing, and there is no need to use the rotor as a force surface, so that the rotor is not easily damaged by pressure, thereby extending the service life of the shaft.

[0034] Reference Figure 1 To facilitate the installation of the bearing, a placement rod 21 is fixed to the mounting base 20. The placement rod 21 is vertically arranged, and the bottom end of the placement rod 21 is fixed to the mounting block. The bearing to be installed is pre-placed on the placement rod 21. During installation, the bearing can be directly removed from the placement rod 21, which is convenient and improves work efficiency.

[0035] Reference Figure 1When the rotor is larger, its weight also increases. To prevent the rotor's output shaft from bending or breaking on the support base 41, two opposing support plates 60 are provided on the mounting base 20. The two support plates 60 are arranged symmetrically about the central axis of the support base 41. One end of the support plate 60, closest to the central axis of the support base 41, is hinged to the mounting base 20, while the other end is tilted upward. A screw 70 is provided below the support plate 60. The screw is vertically inserted into the mounting base 20 and threadedly connected to the mounting base 20. The top end of the screw 70 abuts the bottom wall of the support plate 60.

[0036] When the rotor is large, its sidewalls come into contact with support plate 60. This provides support, distributing the force applied to the rotor's output shaft to prevent bending or fracture at the rotor's output end, thereby shortening the output shaft's service life. Rotating screw 70 causes it to move up and down, and gravity causes support plate 60 to overlap the top of screw 70, changing its inclination angle. This allows it to support rotors of varying sizes, improving its adaptability.

[0037] The implementation principle of a motor bearing assembly tool in an embodiment of the present application is as follows: when in use, first, bearings are sleeved on the output shafts on both sides of the rotor, then the rotor is placed on the mounting seat 20, and at the same time, the output shafts on both sides of the rotor are inserted into the corresponding receiving seats 41, and the bearings are located between the rotor and the receiving seats 41, and then the drive assembly 30 is started, driving the movable seat 40 to drive the receiving seat 41 to move toward the mounting seat 20, so that the receiving seat 41 pushes the bearing close to the rotor until the bearing is pressed into the set position. In this process, because the drive assembly 30 is connected to the two movable seats 40, that is, when the drive assembly 30 is started, it will drive the two movable seats 40 to move synchronously the same distance, thereby achieving the simultaneous completion of the installation of the bearings on the output ends of both sides of the rotor, which is convenient to operate and improves work efficiency.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
