Abstract
Description
Technical Field
[0001] This utility model relates to the field of coupling processing technology, and in particular to a coupling processing clamping and positioning frame. Background Technology
[0002] A coupling is a mechanical component used to connect a driving shaft and a driven shaft, enabling them to rotate synchronously and transmit motion and torque. It compensates for relative displacement between the two shafts, provides cushioning and shock absorption, and can transmit different torques depending on the model. A clamping positioning frame is used in the machining of a coupling for the following reasons: First, it ensures machining accuracy by firmly fixing the workpiece, limiting its movement and vibration, and ensuring that the machined dimensions and shape meet design requirements. Second, it improves machining efficiency by reducing the need for repositioning and adjusting the workpiece during machining, avoiding machining errors caused by displacement, and saving time. Third, it ensures machining safety by preventing the coupling from loosening or being thrown out during machining, ensuring the safety of personnel and equipment. This clamping positioning frame is crucial to the quality, efficiency, and safety of machining this type of coupling.
[0003] When using a traditional coupling machining clamping and positioning bracket, the first step is to inspect and clean it to ensure it is intact and free of impurities. Next, accurately place the bracket according to the coupling's shape and the positioning bracket's reference. Adjust the clamping device to apply a suitable clamping force evenly and securely fix the coupling. During machining, check its fixation status periodically. After machining is complete, loosen the clamping device and remove the coupling according to the specified procedure.
[0004] If traditional couplings are not effectively clamped and fixed during machining, displacement can occur due to cutting forces and vibrations. When turning the outer diameter, radial movement of the coupling makes it difficult to ensure the machined outer diameter meets design requirements, potentially leading to dimensions that are too large or too small. This makes precise assembly with other components difficult. Ineffective clamping and fixing also results in unstable coupling posture during machining, making it difficult to meet geometric tolerances such as cylindricity, roundness, and coaxiality. Furthermore, unstable coupling fixation can cause drilled holes to tilt, compromising relative positional accuracy with other holes or shafts and affecting subsequent installation and use.

This achieves the pushing and auxiliary positioning of the coupling, improving the working accuracy. Attached Figure Description
