Description

Technical Field

[0001] This utility model relates to the field of motor control board technology, specifically an easy-to-install servo motor control board. Background Technology

[0002] Servo motors can control speed and position with extremely high accuracy. They can convert voltage signals into torque and speed to drive the controlled object. The rotor speed of a servo motor is controlled by the input signal and can respond quickly. In automatic control systems, they are used as actuators and have characteristics such as small electromechanical time constant and high linearity. They can convert received electrical signals into angular displacement or angular velocity output on the motor shaft. Servo motors are divided into two main categories: DC and AC servo motors. Their main characteristic is that they do not rotate when the signal voltage is zero, and their speed decreases uniformly as the torque increases. A servo system is an automatic control system that enables the output controlled variables such as the position, orientation, and state of an object to follow any changes in the input target (or given value).

[0003] Servo motors primarily rely on pulses for positioning. Essentially, a servo motor receives one pulse and rotates by the corresponding pulse angle, thus achieving displacement. Because servo motors themselves have the function of generating pulses, they emit a corresponding number of pulses for each rotation angle. This creates a feedback loop, or closed loop, between the pulses received and the received pulses. The system then knows how many pulses were sent to and received by the servo motor, allowing for precise control of the motor's rotation and achieving accurate positioning down to 0.001mm. DC servo motors are divided into brushed and brushless motors. Brushed motors are low-cost, simple in structure, have high starting torque, wide speed range, and are easy to control. However, they require maintenance, which is inconvenient (replacing carbon brushes), generates electromagnetic interference, and is sensitive to environmental conditions. Therefore, they are suitable for cost-sensitive general industrial and civilian applications. Servo motors are controlled by a control circuit board. Existing motor control boards are typically secured with screws or similar structures within the mounting frame. After prolonged use, these screws corrode, making disassembly and maintenance of the motor control board extremely difficult. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-install servo motor control board, which solves the problem that existing motor control boards are fastened with screws and other structures inside the mounting frame. After a long period of use, the screws rust, making it extremely difficult to disassemble and maintain the motor control board.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install servo motor control board, comprising a mounting frame, a control board body disposed inside the mounting frame, a fastening structure fixedly connected to the left side of the control board body, a positioning groove on the left side of the fastening structure, a limiting block engaged inside the positioning groove, a crossbar fixedly connected to the left side of the limiting block, a groove on the left inner wall of the mounting frame, a slot on the left side of the mounting frame, a through hole connecting the slot and the groove, a movable connection between the surface of the crossbar and the interior of the through hole, a first spring sleeved on the surface of the crossbar, a left end of the first spring fixedly connected to the left inner wall of the groove, and a right end of the first spring fixedly connected to the left side of the limiting block. A pull ring is fixedly connected to the left end of the crossbar. The pull ring is located inside the slot. Pulling each pull ring outward causes the limiting block to retract into the groove. Then, tilt the control board body forward and place it into the mounting frame so that the bottom of the control board body contacts the surface of the support plate structure. Then, press the control board body downward so that the support plate structure retracts into the open slot. Then, straighten the control board body and fully insert it into the mounting frame. Slowly release the control board body. At this time, the second spring will push the support plate structure to move upward. The support plate structure will drive the control board body to move upward and drive the locking plate to engage with the limiting slot. Finally, release the pull ring so that the first spring pushes the limiting block to reset and engage with the corresponding positioning slot. This completes the installation of the control board body. Disassembly is done by reversing the above steps.

[0007] Furthermore, the inner bottom wall of the mounting frame is provided with an open groove, and a second spring is fixedly connected to the inner bottom wall of the open groove.

[0008] Furthermore, there are two second springs, which are symmetrically arranged about the central axis of the mounting frame.

[0009] Furthermore, a support plate structure is fixedly connected to the top of the second spring, and the upper surface of the support plate structure overlaps with the bottom of the control board body.

[0010] Furthermore, a limiting groove is formed in the inner top wall of the mounting frame, and a retaining plate is engaged inside the limiting groove. The lower surface of the retaining plate is fixedly connected to the top of the control board body.

[0011] Furthermore, the number of fastening structures is four, and the four fastening structures are arranged at the four corners of the control plate body.

[0012] This utility model provides an easy-to-install servo motor control board. It has the following advantages:

[0013] This easy-to-install servo motor control board uses the interplay of an open slot, a second spring, a support plate structure, a limiting slot, and a locking plate to pre-limit the top and bottom of the control board body. Then, through the interplay of through holes, slots, pull rings, crossbars, grooves, a first spring, a fastening structure, a positioning slot, and a limiting block, the control board body is completely fixed. Furthermore, disassembling the control board body for maintenance is equally convenient. This solves the problem that existing motor control boards, which use screws for fastening within the mounting frame, often become extremely difficult to disassemble and maintain after prolonged use due to screw corrosion.
