TECHNICAL FIELD

[0001] The utility model relates to transformer welding processing technical field, concretely is positioning frock for transformer welding processing. BACKGROUND

[0002] Dry-type transformer is a kind of power transformer that does not use liquid insulating medium, but relies on solid insulating material to realize electrical insulation between winding and core. Its core structure is composed of the core stacked by silicon steel sheet and copper or aluminum winding wrapped with high-strength insulating material, and the overall design pays attention to the balance of heat dissipation and insulation performance.

[0003] When installing protective plates for dry-type transformers in harsh industrial environments, the traditional manual welding method has many pain points.

[0023] Please refer to Figures 1 to 7 The utility model provides two kinds of embodiments:

[0029] The motor one 11 and the motor two 28 are selected to be servo motors. From the structure, the servo motor is mainly composed of a motor body, an encoder and a controller. The motor body usually adopts the design of a permanent magnet synchronous motor or a direct current brushless motor. The rotor is composed of a high-performance permanent magnet, and the stator contains a precisely wound three-phase winding. The high-resolution encoder installed next to the rear part of the motor is a key component of the servo system. It can be photoelectric, magnetic or rotary transformer, which is used to monitor the accurate position and speed of the rotor in real time.

[0030] The working principle starts from the controller receiving position, speed or torque instructions from the upper system. These instructions are compared with the actual operating parameters fed back by the encoder to generate an error signal. The PID algorithm inside the controller dynamically adjusts this error, and outputs a PWM-modulated three-phase current to drive the motor to operate. When the motor rotates, the encoder continuously detects the rotor position, forming a closed-loop feedback, so that the system can correct the deviation from the target value in real time. This closed-loop control mechanism makes the servo motor have a dynamic response characteristic that ordinary motors cannot match, and it can maintain stable motion accuracy even when the load changes.
