A method for repairing crack defects in aluminum alloy specimens using a pointed thin-film acoustic electrode, belonging to the field of aluminum alloy specimen repair, includes: (1) determining the crack repair requirements based on the service environment of the aluminum alloy specimen, and determining the required solder according to the repair requirements; (2) ultrasonically cleaning the inside of the crack; (3) ultrasonically repairing the crack to be repaired; first, the specimen is placed on a heating platform for heating. After heating to the specified temperature, the solder is placed inside the crack. After the solder is completely melted, the pointed thin-film acoustic electrode is inserted into the solder, and the ultrasonic treatment is turned on for repair; (4) after the repair is completed, the microstructure and properties of the weld are tested. This repair method is highly operable. The repair process under ultrasonic action can be carried out directly in an atmospheric environment without the need for protective gas or special environment, reducing repair costs and adapting to various complex shapes, small widths, and large depths of cracks.

The utility model discloses a tool for connecting a hose and a connector in a matched mode, the tool comprises a base, a hose clamping assembly, a connector clamping assembly and a driving assembly, and the base comprises an assembly axis alpha; the hose clamping assembly is connected to the base in a sliding mode. The connector clamping assembly is rotatably connected to the base; the driving assembly is used for driving the connector clamping assembly so that the connector clamping assembly can be close to or away from the hose clamping assembly while rotating around the assembling axis alpha. The driving assembly can drive the connector clamping assembly to rotate around the assembling axis alpha, and meanwhile the connector clamping assembly gets close to or gets away from the hose clamping assembly in the axis direction, so that the connector synchronously completes axial propelling in the rotating process. The composite motion mode of rotation and linear feeding remarkably shortens the matching time, and is particularly suitable for quick assembly scenes with precision requirements.

The application relates to a highway pavement anti-collapse crack detection and filling device and relates to the technical field of pavement construction.The device comprises a carrying vehicle, a crack tester arranged on the carrying vehicle, a stand column vertically connected to the carrying vehicle, a rotating seat rotatably connected to the stand column, a drilling assembly arranged on the stand column and comprising a vertically downward drilling head and a drilling snap ring detachably connected to the rotating seat, the height difference between the drilling head and the drilling snap ring being fixed, a filling assembly arranged on the carrying vehicle and comprising a pouring gun slidingly arranged on the stand column and a filling snap ring detachably connected to the rotating seat, the height difference between the pouring gun and the filling snap ring being fixed, the gun mouth vertically downward, and the pouring gun being used for pouring foaming crack filling agent to the lower part of the pavement, and a lifting assembly arranged on the stand column and used for lifting the drilling assembly or the pouring gun above the drilling point position. The application has the effects of reducing damage to the original pavement and shortening the repair time.
