Description

Technical Field

[0001] This utility model relates to the field of servo motor technology, and in particular to a compact servo motor. Background Technology

[0002] Compact servo motors are small, high-efficiency electric drive systems typically used in applications with limited space and high precision requirements. They employ servo control technology and use a feedback system to precisely control the motor's speed, position, and torque to achieve high-performance drive, and are commonly found in everyday life.

[0003] Existing technologies, such as the utility model patent with publication number CN208479404U, disclose a compact hybrid stepper integrated servo motor. This patent includes a controller, a serial interface cable, and a motor body. The controller includes a housing and control components. The housing includes a rear end cover and a bracket. The control components include a serial interface and two PCB circuit boards. The serial interface includes a connecting plate and a trapezoidal connector. The motor body is mounted on the bracket. One end of the motor body's shaft extends into the rear end cover, and a bushing is fitted onto one end of this end of the shaft. A magnet is fitted onto the other end of the bushing. The motor body's shaft is perpendicular to the PCB circuit boards. A magneto-electric encoder is positioned on the PCB circuit board near the magnet, corresponding to the position of the magnet. This utility model offers high reliability, wide availability, and facilitates product standardization and rapid component replacement. Furthermore, it is easy to assemble, which is beneficial for mass production, thereby reducing costs.

[0004] In daily use, it has been found that when operating servo motors, because general servo motors are fixed and integrated, while compact servo motors are small in size and operate at high efficiency, they are prone to internal maintenance after long-term use. This makes it inconvenient to disassemble and maintain the servo motor. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that, during the operation of servo motors, since general servo motors are fixed and integrated, while compact servo motors are small in size and operate at high efficiency, they are prone to internal maintenance over a long period of time, which makes it inconvenient to disassemble and maintain the servo motor.

[0006] To solve the above-mentioned technical problems, this utility model provides a compact servo motor, including: a mounting plate, a motor cover plate, a motor frame, and a mounting mechanism. The motor cover plate and the motor frame are both disposed on the upper surface of the mounting plate. The motor cover plate and the motor frame are fixedly connected by the mounting mechanism, which is disposed on the surface of the motor cover plate and the motor frame. The mounting mechanism includes two connecting brackets, one end of which is fixedly connected to the side wall of the motor cover plate. An adjusting plate is rotatably connected to the inner wall of the connecting bracket. An insert block is fixedly connected to the surface of the motor frame. The insert block has a U-shaped cross-section. Positioning plates are fixedly connected to both side walls of the insert block. The surface of the adjusting plate is engaged with the inner wall of the insert block. A sliding frame is slidably connected to the surface of the adjusting plate. A rotating shaft is threaded through both sides of the sliding frame. One end of the rotating shaft is threadedly connected to the surface of the positioning plate.

[0007] The effect achieved by the above components is that, during the operation of a compact servo motor, there will be situations where the servo motor needs to be disassembled for maintenance. At this time, the mounting mechanism set on the surface of the motor frame and the motor cover can be used to effectively disassemble and limit the operation of the servo motor.

[0008] Preferably, a protective pad, which is a rubber pad, is fixedly connected to the side of the sliding frame near the surface of the inlay block.

[0009] The effect achieved by the above components is that when the sliding frame is pressed and fixed with the inlay block on one side, the rubber protective pad can effectively protect against excessive compression damage.

[0010] Preferably, both ends of the inner wall of the connecting frame are fitted with coil springs, and the two ends of the coil springs are fixedly connected to the adjusting plate and the connecting frame, respectively.

[0011] The effect achieved by the above components is that the torsional force generated by the coil spring can effectively squeeze and limit the position of the adjusting plate, preventing the adjusting plate from shaking during use.

[0012] Preferably, positioning frames are fixedly connected to both ends of the side wall of the motor frame. The positioning frames are elastic frames. Positioning blocks are fixedly connected to both ends of the side wall of the motor cover. The cross-section of the positioning blocks is barbed, and the surface of the positioning blocks is engaged with the inner wall of the positioning frames.

[0013] The effect achieved by the above components is that, during the process of locking and limiting the motor frame and the motor cover, the positioning block and the positioning frame can be effectively locked and limited, and the motor frame and the motor cover can be temporarily fixed in a convenient and quick manner.

[0014] Preferably, a positioning mechanism is fixedly connected to the surface of the mounting plate at the position corresponding to the motor frame. The positioning mechanism includes a support frame, and an adjusting rod is rotatably connected to the surface of the support frame. The arc surface of the adjusting rod is provided with threads in opposite directions. Both ends of the adjusting rod are threadedly connected to extrusion plates. The cross-section of the extrusion plates is inverted "Z" shape. A limit frame is fixedly connected to the side wall of the motor frame. A limit post is fixedly connected to the inner wall surface of the limit frame. The arc surface of the limit post is inserted into the upper surface of the extrusion plate.

[0015] The effect achieved by the above components is that, during the operation of the servo motor, the positioning mechanism set on the surface of the mounting plate can effectively support and fix the servo motor, facilitate the installation operation on the surface of the servo motor, and help protect the surface of the servo motor.

[0016] Preferably, an auxiliary rod is slidably connected to the bottom surface of the extrusion plate, and one end of the auxiliary rod is fixedly connected to the surface of the support frame.

[0017] The effect achieved by the above-mentioned components is that, during the process of adjusting the position of the extrusion plate, the auxiliary rod can be used for guidance and limitation to prevent the extrusion plate from shifting or deviating in position.

[0018] Preferably, the two ends of the adjusting rod are provided with a plurality of friction grooves, and the plurality of friction grooves are evenly distributed on the two ends of the adjusting rod.

[0019] The effect achieved by the above-mentioned components is that, during the rotation of the adjusting rod, the friction grooves on the arc surface of the adjusting rod can be used to increase friction, making it easier to operate and use the adjusting rod effectively.

[0020] Compared with related technologies, the compact servo motor provided by this utility model has the following beneficial effects:

[0021] By operating the installation mechanism, the fixed limit between the motor frame and the motor cover plate is achieved. The adjustment plates on both sides of the motor cover plate can be connected with the inlay blocks fixed on the surface of the motor frame. At the same time, the sliding frame is used to abut against it. Then, the positioning plates fixed on both sides of the inlay block are threaded and limited by the rotating shaft. This facilitates the disassembly and maintenance of the entire servo motor.

[0022] By operating the positioning mechanism, the entire servo motor is supported and protected. The servo motor can be supported by the support frame set on the surface of the mounting plate. At the same time, the pressing plates at both ends of the adjusting rod are used to press and limit the position of the servo motor, which helps to better position and protect the servo motor.
