4results about How to "Save replacement time" patented technology

This utility model relates to the technical field of sun gear machining fixtures, specifically a sun gear hobbing composite fixture, including a base, a mandrel mounted at the center of the base, a clamping device mounted on the base, and a hydraulic nut located on the top of the mandrel. The clamping device includes a jaw mounted on the base, an adjusting rod rotatably connected to the jaw, and a pressure plate fixed on the base. The pressure plate has a raised long key. The jaw includes a jaw head section, a cylindrical section perpendicularly fixed to the jaw head section, and limiting keys symmetrically fixed on both sides of the cylindrical section. A threaded hole is opened in the center of the cylindrical section. The adjusting rod includes a threaded section, a middle section, and an end fixed in sequence. The middle section has an annular groove, and the end has a hexagonal shape. The threaded section of the adjusting rod is connected to the threaded hole in the cylindrical section. The long key is located in the annular groove of the middle section of the adjusting rod. This fixture can simplify the sun gear alignment steps, improve alignment efficiency, save process changeover time, and significantly improve production efficiency.

This utility model discloses a high-capacity power nickel-metal hydride battery, relating to the field of new energy battery technology. It includes a battery module mounting bracket and a cover plate rotatably connected to its surface. The battery module mounting bracket contains a fixing component, and the cover plate is fixed to the surface of the battery module mounting bracket via the fixing component. This high-capacity power nickel-metal hydride battery allows the battery module to be installed on the battery module mounting bracket via the cover plate and fixing component. Disassembly only requires pulling a lever to disengage the fixing rod from the fixing slot. Under the action of a first telescopic rod and a first spring, the cover plate is lifted, simplifying the installation and disassembly process of the battery module, shortening assembly time, and improving production efficiency. Simultaneously, the fixing component effectively prevents the battery module from loosening or being damaged by external forces such as vibration, ensuring safety and reliability during operation.

The application relates to the field of big data and data processing, and specifically discloses a report processing method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: obtaining a report file, and extracting a structure query statement in the report file; extracting a function, a table name and a field in the structure query statement; replacing the function in the structure query statement based on a mapping relationship to obtain an initial structure query statement; the mapping relationship represents the mapping between the function in a source database of a current running structure query statement and the function in a target database of a to-be-run structure query statement; replacing the table name and the field in the initial structure query statement based on a mapping dictionary to obtain an updated structure query statement; the mapping dictionary represents the mapping between the table name in the source database and the table name in the target database, and the mapping between the field in the source database and the field in the target database. The method can improve work efficiency.

The utility model discloses a kind of heating device for material barrel, including bottom plate, vertical pole is slidably connected on bottom plate, heating band is connected in the side of vertical pole, fixed block with clamping groove is connected in the other side of vertical pole, elastic expansion piece is connected in the side of heating band, the side of elastic expansion piece is slidably connected clamping block, clamping block clamps the clamping groove.The utility model has the advantages that: the device can heat the lower side of material barrel by heating plate, and by setting elastic expansion piece, clamping block and fixed block with clamping groove, it can realize quickly replacing heating band, not only reduce the labor intensity of staff, but also save replacement time.
