The device comprises a hollow base, wherein the upper end of the hollow base is fixedly connected with a fixing frame through a plurality of supporting rods, the inner walls on the left and right opposite sides of the lower end of the fixing frame are rotatably connected with a lower die pressing roller through a rotating shaft, one end of the rotating shaft penetrates through and extends out of the fixing frame and is fixedly connected with a driven gear, the outer wall of the fixing frame is fixedly connected with a driving motor, and an output shaft of the driving motor is fixedly connected with a driving gear meshing with the driven gear. The die pressing device for resin tile production has the advantages that the distance between an upper die pressing roller and the lower die pressing roller can be quickly adjusted according to the required die pressing depth, and use is facilitated.

A shower door assembly with continuous adjustment, comprising a stationary frame, a movable frame and at least two adjustment assemblies disposed between the stationary frame and the movable frame, each of the adjustment assemblies comprising an adjustment device and a locking device for locking the adjustment device, characterized in that, the adjustment device comprises an adjustment element and a carrier element bearing the adjustment element, the adjustment element having smooth side surfaces exposed outside. The locking device of the present invention is able to lock the adjustment element at any position along the side surfaces of the adjustment element, such that the relative distance of the stationary and movable frames can be adjusted continuously.

The invention provides a pipeline vibration-absorption clamping hoop with an adjustable direction, and belongs to the technical field of vibration noise control. The pipeline vibration-absorption clamping hoop with the adjustable direction comprises a clamping hoop assembly and vibration absorption assemblies. The clamping hoop assembly comprises an upper clamping ring, a rubber gasket, a lower clamping ring and conversion connecting blocks. The upper clamping ring and the lower clamping ring are installed on the external circumference surface of the rubber gasket in a sleeving mode after the upper clamping ring and the lower clamping ring are connected in a butting mode. The two conversion connecting blocks are arranged between the upper clamping ring and the lower clamping ring, and the two ends of each conversion connecting block are connected with the upper clamping ring and the lower clamping ring respectively. Each vibration absorption assembly comprises a cantilever rod, mass component end blocks and a mass component middle block, wherein the mass component middle block and the cantilever rod are connected through threads, and the mass component end blocks penetrate through the cantilever rod and then are fixed to the two ends of the mass component middle block. The vibration absorption assemblies are fixedly arranged in threaded holes of the conversion connecting blocks of the clamping hoop assembly through the cantilever rods respectively. The pipeline vibration-absorption clamping hoop is compact in structure and adjustable in vibration absorption direction, can effectively restrain pipeline spectrum vibration of ships, and is low in demand of the installation space and convenient to disassemble, assemble and maintain.

The invention provides a compressor foot pad clamp. The compressor foot pad clamp comprises a rack, a rotating piece, a plurality of movable pieces, a plurality of transmission pieces and a pluralityof clamping pieces; the rotating piece is rotatably arranged on the rack around a preset axis; the plurality of movable pieces are arranged on the rack at intervals, and each movable piece is movablyarranged relative to the rack; the plurality of transmission pieces and the plurality of movable pieces are arranged in a one-to-one correspondence mode, one end of each transmission piece is hinged to the rotating piece, and the other end of each transmission piece is hinged to the corresponding movable piece; when the rotating piece rotates relative to the rack, the rotating piece drives the plurality of movable pieces to move through the plurality of transmission pieces so as to change the distance between at least two movable pieces; and the plurality of clamping pieces are installed on the plurality of movable pieces in a one-to-one correspondence mode so that a plurality of compressor foot pads can be grabbed through the plurality of clamping pieces. By means of the compressor foot pad clamp, the problem that in the prior art, a compressor foot pad clamp is poor in universality is solved.

A rotating device for fuselage assembly of a helicopter is disclosed. The rotating device has a split structure, and comprises a main body, a lower component, a rotating bracket and a hydraulic positioning mechanism. The rotating device of the invention solves the problems that the helicopter fuselage is difficult to be positioned and fixedly connected in the rotating device due to the large sizeand the heavy weight; the relative distance between the roller and the guide rail can be effectively adjusted when the rotating bracket is installed on the main body of the tooling; the rotating device has good openness, so that the rotating device can cooperate with a robot automatic assembly system to carry out hole drill, riveting and the like, can improve assembly speed and assembly quality, and can realize automatic assembly of the fuselage.
