Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically relating to an elastic gap-eliminating device for the guide side of a machine tool guideway. Background Technology

[0002] During machine tool processing, the guiding accuracy of the guide rails directly affects the machining quality and the stability of equipment operation. With increased usage time, gaps can easily form between guide rail pairs due to wear or assembly errors, leading to problems such as vibration, creep, and even positioning deviations when the machine tool is running at high speed or under heavy load. Traditional guide rail gap adjustment methods are mostly rigid clamping or structurally fixed adjustments, lacking elastic compensation capabilities, making it difficult to adapt to dynamically changing working conditions, and the adjustment process is cumbersome and has limited effectiveness.

[0003] In existing technologies, traditional machine tool guideway clearance adjustment devices mostly employ rigid clamping or fixed structural adjustment methods, making it difficult to achieve dynamic compensation and elastic elimination of guideway clearance. This leads to problems such as excessive clearance and decreased guiding accuracy after prolonged machine tool operation due to guideway wear or assembly errors, affecting machining accuracy and equipment stability. Although some devices have certain adjustment functions, their complex structure, inconvenient adjustment, and inability to flexibly adapt to actual working conditions limit their application range.
