Description

Technical Field

[0001] This utility model relates to the field of current transformer manufacturing technology, and in particular to a flipping tool for conveniently wrapping the ring of an inverted current transformer. Background Technology

[0002] The wrapping of the inverted current transformer ring requires manual operation due to the special nature of its insulation structure. In this purely manual operation, the ring is placed on the operating table, with the straight end supported by a bracket. After completing the insulation wrapping of half a circle, two operators need to move the entire transformer body from one end to the other end using the ring as a fulcrum before wrapping the insulation of the other half of the circle.

[0003] The entire wrapping process involves dozens of these operations, which greatly reduces wrapping efficiency. Furthermore, because the center of gravity of the inverted product is located at the wrapping point of the ring, the insulation at the lower end of the ring becomes uneven in thickness due to repeated rolling during these operations, affecting product performance and posing potential quality risks.

[0004] Therefore, in response to the problem that the insulation at the lower end of the ring is repeatedly crushed during the existing main insulation wrapping process, resulting in uneven insulation thickness, a flipping tool for convenient wrapping of the ring of an inverted current transformer can be designed. By flipping the wrapping method, the operation steps of the wrapping process are optimized, the product performance and quality are guaranteed, and the convenience of wrapping the ring of the transformer is effectively improved. Utility Model Content

The second support plate supports the main insulation ring, thereby optimizing the wrapping process, ensuring product performance and quality, and improving the convenience of the transformer ring wrapping operation.

[0014] The beneficial effects of this utility model are:

[0015] 1. During the wrapping operation, the end of the main insulation straight line is placed by setting up a flipping clamp, and the end of the main insulation straight line is clamped and fixed by using an arc-shaped clamp. The support position of the main insulation is changed by lifting and moving the bracket, thereby completing the straight wrapping operation. The scissor lift is moved to the bottom of the main insulation ring, and the height of the second support plate is adjusted by extending and retracting the second hydraulic rod. The main insulation ring is supported by the second support plate. The main insulation is easily flipped by the flipping clamp and the scissor lift, which facilitates the wrapping operation of the main insulation ring. This solves the problem that the wrapping efficiency is low in most current transformer wrapping processes, and the insulation at the lower end of the ring may be repeatedly crushed, resulting in uneven insulation thickness throughout the ring, affecting product performance and posing quality risks. This improves the convenience of current transformer ring wrapping operation. Attached Figure Description

The flipping motor 201 drives the turntable 203 to rotate, and rotating the turntable 203 causes the main insulation 1 to flip. The clamping assembly includes a bidirectional adjusting screw 301 and a servo motor 3. 02 and connecting block 303; a bidirectional adjusting screw 301 is provided on the inner side of the turntable 203, and a servo motor 302 is provided on the outer side of the turntable 203.
