Description

Technical Field

[0001] This utility model relates to the field of fixing fixture technology, and in particular to a disc fixing fixture. Background Technology

[0002] A disc fixture is a mechanical device whose main function is to fix disc-shaped objects and ensure that they maintain a stable position and posture during processing, testing, assembly and other operations. Its purpose is to restrict the degree of freedom of the disc and prevent the disc from translating, rotating and vibrating when subjected to external forces such as cutting forces during processing, squeezing forces during assembly and detection forces during testing, which would affect the accuracy of operation.

[0003] Existing disc clamping fixtures lower pressure plates by tightening bolts, pressing the disc onto the fixture's base and positioning plate. The shape and position of the pressure plates are designed according to the disc's shape and the location where pressure needs to be applied. For larger discs, multiple pressure plates may be used, distributed near the disc's edge and center to ensure even distribution of clamping force, thus achieving the effect of fixing the workpiece. However, in actual operation, due to the difficulty in achieving perfectly consistent bolt tightening, as well as the disc's shape errors and surface flatness differences, uneven clamping force can easily occur. This results in excessive clamping force in some areas and insufficient clamping force in others, leading to disc deformation during processing. Existing technology addresses this by... Personnel use torque wrenches with torque display and adjustment functions to pre-set appropriate torque values ​​based on the material, size, and processing requirements of the disc before clamping it. They then strictly follow the set torque values ​​to ensure that the clamping force applied to each bolt is consistent. However, after the screws have undergone repeated tightening and loosening processes, especially under high clamping forces, the thread surface will gradually wear due to friction, causing the material on the thread surface to gradually peel off. This reduces the fit accuracy between the screw, nut, and threaded hole, resulting in the thread not being able to provide sufficient friction to maintain the clamping force. Consequently, the disc becomes unstable during processing, causing damage to the processing equipment and products. Utility Model Content
