Description

Technical Field

[0001] This utility model relates to the field of testing technology, specifically a universal maintenance bench for a demagnetizing current controller. Background Technology

[0002] Currently, when the demagnetizing current controller malfunctions, it can only be repaired on a prototype. The prototype is large and heavy, making it inconvenient to move, and is generally fixed in the laboratory for use.

[0003] When overhauling a demagnetizing current controller, the magnetic sensor needs to be debugged as well. However, the magnetic sensor is usually placed as a separate component on a dedicated platform. During maintenance, at least two people are required: one to manually rotate the magnetic sensor and the other to measure the signal. Single-person operation is not possible, making maintenance inconvenient and inefficient. Furthermore, because the magnetic sensor is placed on a flat surface, it cannot rotate smoothly horizontally during manual rotation, resulting in slight vertical wobble and significant human error in signal measurement. Moreover, since the rotation speed and angle of the magnetic sensor cannot be precisely controlled, quantitative analysis of the measured signal is impossible. Therefore, during maintenance, only a rough observation of whether the key signals of the demagnetizing current controller change accordingly is possible; the magnitude of these changes cannot be analyzed, and the dynamic performance of the demagnetizing current controller cannot be tested. Summary of the Invention

[0004] The purpose of this utility model is to provide a universal maintenance bench for demagnetizing current controllers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a universal maintenance platform for a demagnetizing current controller, comprising a base plate, several self-locking casters mounted on the bottom of the base plate, a cabinet and a support base fixed above the base plate, a display screen and an operation panel mounted on the support base, a maintenance interface for inserting the demagnetizing current controller during testing provided on the top of the cabinet, a conveyor plate rotatably connected to the support base, several workstations provided on the conveyor plate, a servo motor fixed inside the upper end of the support base, a reducer connected to the end of the motor shaft of the servo motor, a fixed rod fixed to the output end of the reducer, a turntable fixed to the top of the fixed rod, a magnetic sensor mounted on the turntable, and an adjustment component for adjusting the horizontal position of the magnetic sensor also provided on the turntable.

[0006] By adopting the above technical solution, the universal maintenance bench for the demagnetizing current controller has the advantages of convenient operation. This maintenance bench has a maintenance interface on the cabinet for connecting the demagnetizing current controller. It relies on the operation panel and display screen for display and operation, and is mainly responsible for the signal acquisition, processing, and display of the demagnetizing current controller. The turntable's speed and angle are precisely controlled by a servo motor. The magnetic sensor is fixedly mounted on the turntable and its position can be adjusted using adjustment components. When the turntable rotates, the magnetic sensor rotates accordingly, thus enabling precise control of the magnetic sensor's rotation angle and speed, achieving continuous and accurate signal measurement. The servo motor is controlled by pulse control. Maintenance personnel only need to connect the demagnetizing current controller to be tested to the maintenance interface. The maintenance bench will automatically acquire and analyze the key signals of the demagnetizing current controller, then determine the fault point, and display the fault problem and repair suggestions on the display screen. The above maintenance process can be completed by only one person, improving maintenance efficiency. Fixing the magnetic sensor on the turntable ensures smooth rotation and avoids human error caused by manual rotation. Furthermore, by precisely controlling the rotation angle and speed of the magnetic sensor, quantitative analysis of the measurement signal can be performed during maintenance. This allows for quantitative analysis of the relationship between the changes in the key signals of the demagnetizing current controller and the changes in the input signal, and enables testing of the dynamic performance of the demagnetizing current controller.

The fixed base is fixed above the turntable, the sliding groove is formed in the fixed base for the bearing seat to slide horizontally, the screw is threadedly connected to the bearing seat, and the magnetic sensor is fixed to the bearing seat by screws.

[0008] By adopting the above technical solution, rotating the screw can drive the support seat to slide within the sliding groove on the fixed seat, thereby realizing the translation of the magnetic sensor within the turntable. A level can be used to easily adjust the horizontal position of the magnetic sensor.

[0009] Preferably, the sliding groove is a dovetail groove, and the cross-section of the bearing seat is a dovetail shape that matches the sliding groove.

[0010] By adopting the above technical solution, when the sliding groove adopts a dovetail groove, it has the advantage of stable sliding.

[0011] Preferably, the screw is externally threaded with a pressure ring, and a spring washer is provided between the pressure ring and the fixed seat.

[0012] By adopting the above technical solution, the screw can be locked using a pressure ring and a spring washer.

[0013] Preferably, the plurality of workstations are separated by partitions, and the plurality of partitions are connected and fixed to each other.

[0014] By adopting the above technical solution, multiple instruments to be tested can be placed on the conveyor tray, and the separator can separate them.

[0015] Preferably, two door stops are hinged to one side of the cabinet.

[0016] By adopting the above technical solution, the door can facilitate the use of the storage area and electrical installation area inside the cabinet.

[0017] Preferably, the top surface of the cabinet and the wall surface of the support base are respectively provided with a layer of anti-fouling coating.

[0018] By adopting the above technical solutions, the antifouling coating can improve the antifouling effect.

[0019] Compared with existing technologies, the advantages of this utility model are as follows: The universal maintenance platform for demagnetizing current controllers is convenient to operate; the platform has a maintenance interface on the cabinet for connecting the demagnetizing current controller, and relies on the operation panel and display screen for display and operation, mainly responsible for signal acquisition, processing, and display of the demagnetizing current controller.

Maintenance personnel only need to connect the demagnetizing current controller to be tested to the maintenance interface, and the platform will automatically acquire and analyze the key signals of the demagnetizing current controller, then determine the fault point of the demagnetizing current controller, and display the fault problem and repair suggestions on the display screen. The above maintenance process can be completed by only one person, improving maintenance efficiency; fixing the magnetic sensor on the turntable ensures smooth rotation and avoids human error caused by manual rotation. Furthermore, by precisely controlling the rotation angle and speed of the magnetic sensor, quantitative analysis of the measurement signal can be performed during maintenance. This allows for quantitative analysis of the relationship between the changes in the key signals of the demagnetizing current controller and the changes in the input signal, and enables testing of the dynamic performance of the demagnetizing current controller.
