2results about How to "Reduce wear effect" patented technology

This utility model relates to the field of transformer technology, and more particularly to a transformer with multi-layer coating. It includes a main body and a recess formed on the main body, with a wear-resistant layer coated inside the recess. Two protective plates (first type) corresponding to the recess are provided on the main body. A moving component is provided on the main body to move the first protective plates. A second protective plate (second type) protecting the recess is placed between the two first protective plates. Uniformly distributed intercepting rods protecting the transformer are integrally connected between the two second protective plates. This utility model protects the transformer by coating the recess with a wear-resistant layer, thereby reducing external wear. The moving component on the main body prevents the wear-resistant layer from being applied, and the reinforcing mechanism locks the position of the first protective plates, enabling the first and second protective plates and the intercepting rods to provide impact protection for the main body, thus protecting the internal components.

The utility model discloses a kind of tool changing mechanism of vertical machining center with self-locking function, the utility model relates to tool changing mechanism technical field, including base, the center of base upper end is fixed with connecting column, the center position of connecting column side wall is rotatably provided with tool holder;The utility model has the advantages that tool changing mechanism can lock tool, can ensure that tool is always firmly locked in the whole process of tool changing operation and tool holder rotation, eliminates the situation that tool and tool holder are separated, effectively avoids the occurrence of tool dropping accident;Tool changing mechanism can drive the ball below it to roll when tool holder rotates, effectively reduces the friction and abrasion between each component in tool holder rotation process by the rolling effect of ball, significantly prolongs the service life of tool holder and related components, and vibration generated when tool holder rotates can also be absorbed, further weaken the abrasion influence caused by vibration.
