Problems solved by technology

This method can ensure smooth joints and good air tightness in a short period of time, but due to the different materials of the colloid and the guide rail itself, its long-term stability and thermal stability are poor
The installation, production and testing of ultra-long air bearing guide rails have always been an important issue in the field of ultra-precision machining, but there is currently no mature technical solution that can be used for reference

Embodiment Construction

[0022] The installation method of the ultra-long air-floating guide rail of the present invention is that the first section guide rail 1 is installed and positioned, a mobile measuring platform 2 that can slide along the guide rail is installed on the guide rail 1, and a measuring device 3 is installed on the mobile measuring platform 2. The other guide rail 1 is connected with the first guide rail 1, slide the mobile measuring platform 2 to the joint of the two guide rails 1, measure the straightness of the upper surface and both sides of the joint of the two guide rails 1 through the measuring device 3, and press Calibrate according to the requirements of installation accuracy, and then connect the next section of guide rail 1 according to the above method until the last section of guide rail 1 is installed. This method of real-time control of installation accuracy can ensure the accuracy of the super-long air-floating guide rail, so that the air cushion will not leak at the ...

Abstract

This invention discloses an installation method and a device for supper long gas-floated guideways, which localizes a first section part and installs a mobile test platform on it sliding along the guiedway and installs a measurement device, connects the first section with another section and moves the platform to the joint of the two guideways to test the joint accuracy and correct it according to the requirement of installation accuracy, then connects a next section in terms of the said method till to the finish. The device includes groundsill, an adjustable pad iron, two or more than two guideways connected end to end, supporting beams and bases supported on the groundsill by the adjustable pad iron, the supporting beams are set in the installation slots on the base and the guideways are fixed on the supporting beams by fasteners.

Description

technical field [0001] The invention relates to the field of precision instruments, in particular to a method for installing an ultra-long air-floating guide rail and a device designed according to the method. Background technique [0002] Air bearing guide rail (gas static pressure guide rail) is the core technology in ultra-precision machining. It is generally used on ultra-precision machine tools, and the most common one is 1 to 2 meters long. The air bearing guide rail has no friction interference in the direction of movement, and it has good rigidity in the direction of restraint, which can well meet the needs of ultra-precision machining or testing. The precision of the air-floating guide rail is high, and the air-floating gap is required to be small, and the general working gap is less than 20 μm. Super-long air-floating guide rails are generally spliced ​​by multiple guide rails. Under the premise of ensuring high straightness, this must require smooth seams, good a...
