Description

Technical Field

[0001] This utility model relates to the technical field of motor encoder bracket structure, and in particular to a motor encoder bracket structure. Background Technology

[0002] As a signal feedback device, the encoder is installed and connected to the motor through components such as encoder connectors, connecting shafts, and couplings, and is crucial to the normal operation of the motor. When connecting the encoder to the motor, the accuracy requirements for radial runout and shaft misalignment during encoder operation necessitate careful consideration of the bracket structure used for encoder installation.

[0003] Existing motor encoder bracket structures are mostly fixed, which cannot provide effective support and angle adjustment for motor encoder installation in different environments. Therefore, it is necessary to design a motor encoder bracket structure. Utility Model Content

[0004] Therefore, it is necessary to provide a motor encoder bracket structure to address the technical problem that the aforementioned motor encoder bracket structure cannot be angle-adjusted.

[0005] To achieve the above objectives, this utility model provides a motor encoder bracket structure, including a base and a mounting bracket. A U-shaped frame is mounted on the base, and slots are provided on both sides of the U-shaped frame. Pressure plates are slidably engaged in the slots. A rotating shaft is rotatably mounted on the U-shaped frame, and the top end of the rotating shaft is hinged to the mounting bracket. Both pressure plates are provided with arc-shaped grooves centered on the rotating shaft. Connecting blocks are slidably engaged in the arc-shaped grooves. Connecting rods are hinged to the connecting blocks, and the end of the connecting rod away from the connecting block is hinged to the mounting bracket. A drive mechanism is mounted on the U-shaped frame, and the output end of the drive mechanism is connected to the rotating shaft for transmission. A threaded rod is rotatably mounted on one of the pressure plates, and a mounting plate is mounted on the U-shaped frame. The threaded rod is threadedly connected to the mounting plate.

[0006] Preferably, the drive mechanism includes a first gear, the bottom of which is mounted on a rotating shaft, and a second gear is rotatably mounted on a U-shaped frame, with the first gear and the second gear meshing together.

[0007] Preferably, the threaded rod two has a locking block on it, and the gear two has a square limiting groove. The locking block is slidably engaged in the square limiting groove, and the threaded rod two is configured to cooperate with the U-shaped frame.

[0008] Preferably, rotating wheels are rotatably installed on both sides of the bottom of the two connecting blocks, and the rotating wheels abut against the inner wall of the arc-shaped groove.

[0009] Preferably, both connecting blocks are rotatably mounted with universal support wheels at their bottoms.

[0010] Preferably, the rotating shaft and the two connecting rods are provided with rounded corners.

[0011] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0012] 1. The pressure plate moves up and down via the threaded rod, which in turn drives the mounting bracket to deflect via the connecting rod. It can also drive the connecting rod on the other side to deflect in the opposite direction, thereby allowing the mounting bracket to adjust its tilt angle around the top of the rotating shaft.

[0013] 2. When the rotating shaft is driven to rotate by the drive mechanism, the mounting bracket can drive the connecting rod to slide in the arc groove, thereby enabling the entire mounting bracket to rotate to a certain extent, thus coping with the installation of motor encoders in various environments.

[0019] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] Please see Figures 1 to 4This application provides a motor encoder bracket structure suitable for larger motor encoders. It includes a base 1 and a mounting bracket 2. A U-shaped frame 3 is fixedly mounted on the base 1. Slots 19 are provided on both sides of the U-shaped frame 3. Pressure plates 4 are slidably engaged within the slots 19. A gap and friction exist between the pressure plates 4 and the slots 19, thereby balancing the pressure inside and outside the slots 19 and reducing the shaking of the mounting bracket 2 caused by motor encoder vibration through friction. A rotating shaft 5 is rotatably mounted on the U-shaped frame 3. The top end of the rotating shaft 5 is connected to the mounting bracket 2. The hinged joint has an arc-shaped groove 6 on both pressure plates 4 with the rotating shaft 5 as the center. A connecting block 20 is slidably engaged in the arc-shaped groove 6. A connecting rod 7 is hinged on the connecting block 20. The end of the connecting rod 7 away from the connecting block 20 is hinged to the mounting frame 2. A drive mechanism 8 is mounted on the U-shaped frame 3. The output end of the drive mechanism 8 is connected to the rotating shaft 5 for transmission. A threaded rod 9 is rotatably mounted on one of the pressure plates 4. A mounting plate 10 is fixedly mounted on the U-shaped frame 3. The threaded rod 9 is threadedly connected to the mounting plate 10. The above hinges are preferably connected by a pin.

[0021] In this embodiment, the threaded rod 9 is threadedly connected to the mounting plate 10. When the threaded rod 9 rotates, it drives the pressure plate 4 to move up and down. The pressure plate 4 then drives the connecting rod 7 to move up and down within the slot 19, allowing the mounting frame 2 to rotate around the hinged end of the rotating shaft 5. Meanwhile, the connecting rod 7 on the other side, driven by the mounting frame 2, can move up and down in the opposite direction. The hinges between the connecting rods 7 on both sides and the mounting frame 2, as well as the hinges between the connecting rods 7 and the connecting block 20, ensure that when the mounting frame 2 rotates around the top of the rotating shaft 5, the connecting rod 7... The connecting rod 7 can balance lateral movement through hinge deflection. After adjustment, the threaded rod 9 and the mounting plate 10 are threaded together to achieve fixation. The drive mechanism 8 can drive the rotating shaft 5 to rotate. The drive mechanism 8 can drive the motor. Manual rotation drive is preferred. Under the connection of the mounting frame 2, the two connecting rods 7 can drive the connecting block 20 to slide in the arc groove 6 on its corresponding pressure plate 4. Finally, the mounting frame 2 can deflect concentrically around the rotating shaft 5 to a certain extent, so that the motor encoder can be installed in different directions.

[0022] In some embodiments, in order to facilitate the drive mechanism 8 to drive the rotating shaft 5 to rotate, a gear 11 is installed at the bottom of the rotating shaft 5, and a gear 2 12 is installed at the output end of the drive mechanism 8, with the gear 11 and the gear 2 12 meshing together.

[0023] In some embodiments, to further improve the stability of the motor encoder after installation, a threaded rod 21 is provided, on which a locking block 22 is fixedly installed. A square limiting groove is provided on the gear 12, and the locking block 22 is slidably engaged in the square limiting groove. The threaded rod 21 is configured to cooperate with the U-shaped frame 3. During use, the threaded rod 21 can be pulled up through the locking block 22, so that the locking block 22 is no longer engaged in the U-shaped frame 3. Then, the threaded rod 21 drives the locking block 22 to rotate, thereby driving the gear 12 to rotate through the engagement of the locking block 22 with the square limiting groove. After the rotation adjustment is completed, the threaded rod 21 is lowered so that the locking block 22 is simultaneously engaged in the square limiting groove and the groove provided in the U-shaped frame at its bottom, thereby preventing the rotating shaft 5 from shaking through the locking block 21.

[0024] In some embodiments, in order to reduce the friction between the connecting block 20 and the inner wall of the arc groove 6 when the connecting block 20 slides in the arc groove 6, rotating wheels 13 are rotatably installed on both sides of the bottom of the two connecting blocks 20, and the rotating wheels 13 abut against the inner wall of the arc groove 6.

[0025] In some embodiments, to reduce the friction between the connecting block 20 and the bottom wall of the arc groove 6 when the connecting block 20 slides in the arc groove 6, universal support wheels 14 are rotatably mounted on the bottom of both connecting blocks 20.

[0026] In some embodiments, to prevent the rotating shaft 5 and the connecting rod 7 from colliding with the mounting bracket 2 and the connecting block 20 when they rotate, rounded corners are provided on the rotating shaft 5 and the two connecting rods 7.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
