Three-dimensional linear rolling guide rail

Abstract

The invention provides a three-dimensional linear rolling guide rail. The guide rail comprises X-direction sliding rails, X-Y direction two-dimensional sliding bases, a Y-Z integrated two-dimensionalsliding rail and Z-direction sliding bases, wherein the Y-Z integrated two-dimensional sliding rail comprises a Y-axis sliding rail body and at least one Z-axis sliding rail body fixedly integrated with the Y-axis sliding rail body; the Z-axis sliding rail bodies are connected with the Z-direction sliding bases which slide along the Z axis; the Y-axis sliding rail bodies are connected with the atleast one X-Y direction two-dimensional sliding bases which slide along the Y axis; and the X-Y direction two-dimensional sliding bases are connected with the X-direction sliding rails which slide along the X axis. When the three-dimensional linear rolling guide rail is used for forming a corner limiter, the three-dimensional sliding rail is only connected with an upper mounting plate used for mounting an optoelectronic device and a lower mounting plate connected with a foundation, the structure is compact, and connecting components (plates) adopting a one-dimensional guide rail structure anda large number of bolts are abandoned; and in addition, the structural rigidity is good, and a corner limiting function is stable and reliable.

Description

technical field [0001] The invention relates to the field of vibration isolators, in particular to a three-dimensional linear rolling guide. Background technique [0002] At present, the attitude measurement and control photoelectric equipment, such as inertial navigator, gyroscope, radar, optical platform, etc., are mainly installed on the vehicle by rigid installation, and there are also a small amount of elastic installation. [0003] 1 rigid mount [0004] The coordinates (X 0 , Y 0 ,Z 0 ) and the state of pose parameters (ѰX, ѰY, ѰZ) maintain good stability and reliability. However, the requirements for the environmental adaptability of such electronic devices are relatively high, especially for their ability to resist strong shocks and strong vibrations. Sometimes even if their electrical properties and structure are reinforced, they cannot meet the requirements for use, resulting in a state where no qualified optoelectronic products are available. At this time, ...

The second is the six-link shock isolator given in the "Design of Shock Isolator for Shipborne Laser Inertial Navigation System" without compensation of photoelectric signal equipment for angular displacement error

[0026] 1. The processing accuracy and shape and position tolerance requirements of the connecting parts are very high;

[0027] 2. Multi-layer screw installation, resulting in poor overall structural rigidity, under strong impact, the corner limit accuracy decreases

The advantage is that the X-axis and Y-direction sliding seats are integrated, which reduces the connecting pieces between the X-axis and Y-axis sliding seats. The disadvantage is that the Z-axis still needs additional connecting pieces.
