An additive repair device for internal threads is provided. The device includes a moving assembly, a rotating assembly, a speed regulation assembly, a gear assembly, an additive assembly, and a connecting assembly. The moving assembly includes a drive part and a linear movement mechanism. The additive assembly is connected to the linear movement mechanism through the connecting assembly. One end, which is far away from the drive part, of the linear movement mechanism is connected to an input end of the speed regulation assembly through the gear assembly. The rotating assembly includes a clutch mechanism and a clamping mechanism. The clutch mechanism includes a clutch outer gear and a clutch inner gear. The clutch outer gear is arranged at an output end of the speed regulation assembly. The clamping mechanism is fixed to one end, which is far away from the speed regulation assembly, of the clutch inner gear.

An electromagnetic pulse additive device for a connection ring of a heavy-lift carrier rocket is provided. The device includes brackets, a gear disk rotatably matched with the annular ground rail through a plurality of rolls arranged in a circumferential direction of the gear disk, a first drive motor, an annular ground rail, and a guide rail in a semicircular shape arranged at top ends of the brackets. An output shaft of a first drive motor is fixedly provided with a first drive gear engaged with the gear disk. The guide rail is slidably provided with three lifting modules which respectively drive a bending module, an electromagnetic head arranged electromagnetic coil electrically connected with a capacitor and a discharge circuit, and a rotational friction and extrusion module including a second drive motor and a friction bar fixedly connected to an output shaft of the second drive motor to rise and fall.

The present invention discloses an automatic grinding device for weld beading on the inner wall of a pipeline with a large length to diameter ratio. The automatic grinding device includes a supporting module, and a walking module, a working module and a control module which are arranged on the supporting module, where the walking module is used for moving the supporting module to the butt welding position of the pipeline; the working module is used for grinding the weld beading; and the control module is used for controlling the actions of the walking module and the working module. When the pipeline rotates along the axial direction, the position of the grinding device can remain at the bottom of the pipeline, rather than rotating together with the pipeline, and the elimination of weld beading on the whole circumference at the butt welding position of the pipeline is realized.
