This utility model discloses a polishing device for ceramic preparation molds, relating to the field of ceramic preparation molds. It addresses the problem in existing technologies where operators struggle to control the contact force between the mold and the polishing disc during polishing, thus affecting the stability of the polishing quality. The rotating shaft extends from its front end into a fixed cylinder and is fixedly connected to a force transmission cylinder. A telescopic groove is provided in the middle of the force transmission cylinder's interior. A guide rod is fixedly connected to the middle of the rear end face of the telescopic groove. A telescopic shaft is located inside the telescopic groove and at the front end of the guide rod. A push ring is connected to the front end of the middle of the guide rod. A force transmission spring is provided on the guide rod between the push ring and the rear end face of the telescopic groove. By incorporating the force transmission spring and the telescopic shaft structure, operators can obtain stable polishing force without precise pressure control, improving the uniformity and consistency of the polishing quality.

This application provides a smart energy meter insulation testing and fixing device, relating to the field of energy meter fixing. It includes a base, with a placement groove on the upper surface of the base. A bearing plate is slidably connected to the inner wall of the placement groove. The inner wall of the placement groove has a sliding groove and a clearance groove, which communicate internally. A displacement plate is slidably connected inside the sliding groove. A ratchet is fixedly connected to the upper surface of the displacement plate, and a telescopic rod is rotatably connected to the lower surface of the displacement plate. This application, through the cooperation of the base, placement groove, bearing plate, sliding groove, clearance groove, displacement plate, ratchet, telescopic rod, telescopic cylinder, L-shaped rod, and arc-shaped rod, achieves the following: when the energy meter is pressed down, the bearing plate drives the arc-shaped rod to rotate, thereby driving the displacement plate to retract inward and quickly clamp the energy meter using the self-locking action of the ratchet and the sliding plate. This solves the problem of time-consuming manual fixing and disassembly, and improves the efficiency of batch testing.

The bottom cover is of a hollow structure, and a damping device is arranged in the bottom cover. The middle seat is matched with the top cover to form a sealed space, and an electronic element is mounted in the sealed space through a bolt; a first elastic cushion and a second elastic cushion are arranged on the rod part of the bolt in a penetrating manner, and the second elastic cushion and the first elastic cushion are respectively clamped on the upper side and the lower side of the electronic element; the upper end and the lower end of the first elastic cushion and the upper end and the lower end of the second elastic cushion are each provided with a first groove, and the first grooves are annularly formed in the outer side of the rod part in a surrounding mode. According to the utility model, flexible contact between the electronic element and the buoy can be realized, and the shock resistance of the electronic element is improved.

This utility model discloses a large-scale hydro-generator guide vane clamping fixture, aiming to solve the problems of inconsistent support fixing points, easy damage to the guide vanes, incomplete clamping, and low standardization in existing clamping fixtures. The fixture is distributed at equal angles around the sliding rotor and includes a support base, support columns, guide vanes, and support bolts. The support columns connect to both ends of the guide vanes, and the support bolts are located in the middle of the guide vanes between the guide vanes and the support base. The support base has a connecting sleeve that is threadedly connected to the support column. Both ends of the guide vanes have rubber-coated pads, and the middle section is connected to the support bolts via the support sleeve and connecting block. The support bolts include a centering nut and a handwheel. This fixture ensures uniform clamping dimensions for the guide vanes, avoids damage and incomplete clamping, improves operational standardization, and provides an accurate benchmark for unit installation and commissioning.

This invention relates to the field of weld seam grinding, and more particularly to a straight seam welded pipe weld seam grinding system, aiming to alleviate the problem of sharp corners remaining after weld seam grinding in related technologies. The straight seam welded pipe weld seam grinding system includes a smooth transition mechanism, which comprises a first drive assembly and a first abrasive belt disposed on the first drive assembly. The first abrasive belt is configured to rotate about a rotation axis parallel to the weld pipe axis during grinding. A lifting frame mechanism is also included, which drives the smooth transition mechanism to move along a straight line, so that the straight segment of the first abrasive belt fits against the weld seam from the top of the weld seam. By incorporating the smooth transition mechanism, this straight seam welded pipe weld seam grinding system can significantly eliminate sharp corners in the weld seam, thereby ensuring the quality of subsequent anti-corrosion coating.
