The utility model discloses a device for releasing the twist alarm of inner milling center frame, which is used for milling the main journal of crankshaft and the connecting rod journal. A sliding table is arranged on the left side of the center frame and connected with the guide rail horizontally arranged on the bed. A connecting rod is fixed on the sliding table. A frame is fixedly connected with the sliding table. A connecting plate is arranged on the frame. A through hole is drilled on the lower right side surface of the center frame. A second oil cylinder is arranged on the lower right side surface of the center frame. A guide hole is drilled on the end surface of the center frame close to the second oil cylinder. A traction mechanism is arranged between the two guide grooves and at the lower end of the center frame. A first oil cylinder is vertically downwardly arranged on the upper surface of the center frame above the traction mechanism. The piston rod of the first oil cylinder is directly inserted into the square hole of the center frame. When the center frame is horizontally moved, the sliding table drives the connecting rod and the connecting plate to move. The piston rod of the first oil cylinder is inserted into the connecting rod in the guide hole. The piston rod of the first oil cylinder tightly presses the connecting plate on the lower side of the square hole. Since the center frame has three points that can be affected by the traction force, the parallel traction force between the center frame and the guide rail can be effectively maintained.

The utility model relates to the technical field of pipe processing, and discloses a pipe production device convenient to fix, which comprises a mounting plate, and a driving motor is fixedly mounted on the surface of the mounting plate. According to the pipe production device convenient to fix, a rotating rod rotates on the surface of a movable frame to fix the surface of a pipe, then a driving motor drives a threaded rod to rotate, the movable frame moves to drive the pipe to be pulled, a rolling shaft frame guarantees stable movement of the pipe, meanwhile, the rotating motor rotates to drive a lead screw to rotate, and a moving block moves; secondly, due to the arrangement of the rubber protruding blocks, the cambered surface of the pipe is better attached, along with traction of the pipe and rotation of the roller, the rubber pad is attached to the surface of the pipe, and the rubber protruding blocks limit the cambered surface of the upper side of the pipe; therefore, the traction after the pipe is fixed is ensured.

The application discloses a cable processing threading machine, and relates to the technical field of cable processing, which comprises a workbench, a traction assembly, a touch panel, a fixed rack and a movable rack, and further comprises two groups of threading assemblies, each of which comprises a top plate, a limiting piece, a flexible rope and a plurality of threading blocks. Through the improved combination state of the threading blocks and the cooperation of the flexible rope, all the drooping threading blocks can be quickly and synchronously reset to a horizontal linear type through the "pulling" action of the flexible rope. For multi-core gray cable, the original scheme needs to be manually pushed back block by block, while the present scheme only needs to be pulled once, and the operation time is shortened from minutes to seconds. The flexible rope allows the threading blocks to freely find the lowest energy state under the action of gravity, and even if the gap between the plug-in surfaces changes due to slight wear, the V-shaped state can still be naturally formed, reducing the operation difficulty of the user.
