2results about How to "Coaxiality error is small" patented technology

This utility model provides a clamping assembly for testing the peel force of optical fiber coatings. It relates to the field of material adhesion testing technology. The clamping assembly includes a single-column tensile testing machine. A lower clamp and an upper clamp are fixedly mounted on the single-column tensile testing machine. A mounting block is fitted onto the lower clamp. Two support frames are fixedly mounted between the inner walls of both sides of the mounting block, and both support frames are in contact with the lower clamp. Two rectangular blocks are fixedly mounted on one side of the mounting block. A threaded sleeve is rotatably mounted between the two rectangular blocks. Two threaded rods are threaded onto the threaded sleeve. Connecting arms are fixedly mounted at the ends of the two threaded rods that are far apart from each other. Adapter blocks are fixedly mounted on the tops of the two connecting arms. This utility model has the advantages of being able to calibrate the center lines of the lower clamp and the upper clamp, reducing coaxiality errors between them, and being quick and convenient to operate.

This utility model relates to the field of planetary reducer technology, specifically disclosing a fixing frame for processing planetary reducer housings, including: a base, a clamping mechanism on the top surface of the base, a top frame connected to the clamping mechanism via a support rod, and a pressing mechanism between the top frame and a pressing plate; the clamping mechanism drives the clamping plate to move via an adjustable bidirectional lead screw and sprocket chain transmission, and the pressing mechanism presses down on the pressing plate via a displacement bidirectional lead screw. Furthermore, the clamping plate is equipped with a rubber buffer pad, which, together with the auxiliary positioning mechanism's double-headed motor, unidirectional lead screw, and guide structure, achieves multi-directional coordinated fixing and adaptive positioning of the housing. This utility model solves the problems of insufficient positioning constraints and clamping deformation in traditional fixing frames, improves the stability and precision of housing processing, and enhances the applicability to housings of different specifications.
