Description

Technical Field

[0001] This invention relates to the field of circular arc guide rail pair technology, specifically to a method for installing circular arc guide rail pairs. Background Technology

[0002] The circular arc guide rail pair is a guiding and load-bearing component of the support mechanism. Its performance directly affects the operating accuracy and load-bearing capacity of the mechanism. It is required to have characteristics such as high load-bearing capacity, high rigidity, high stability, high operating accuracy, long service life, low coefficient of friction, and surface corrosion resistance.

[0003] The ultra-large circular arc guide rail pair is a type of circular arc guide rail pair capable of withstanding comprehensive loads, including large axial and radial loads and overturning moments. It consists of a guide rail with an outer diameter of 16240mm and multiple slider assemblies mounted on the guide rail. When the diameter of the circular arc guide rail pair exceeds 9mm, the large size of the parts makes it difficult to guarantee the required machining accuracy. Continuous adjustments are necessary during installation to ensure the final installation accuracy of the guide rail pair. Currently, there is a lack of installation methods specifically for ultra-large circular arc guide rail pairs. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a method for installing arc guide rail pairs, which is designed for ultra-large arc guide rail pairs. It allows for continuous adjustments during the installation process to ensure the installation accuracy of the guide rail pairs. The steps and measurement methods are reasonable, thereby improving installation efficiency.

[0005] To achieve the above objectives, the present invention provides a method for installing an arc-shaped guide rail pair. The arc-shaped guide rail pair includes a guide rail base. The guide rail base is provided with a first inner guide rail, a second inner guide rail, a first outer guide rail, and a second outer guide rail. The first inner guide rail and the second inner guide rail are arranged opposite to each other at the same radial position on the guide rail base. The first outer guide rail and the second outer guide rail are arranged opposite to each other at the same radial position on the guide rail base. A plurality of first inner slider assemblies are provided on the first inner guide rail. A plurality of second inner slider assemblies are provided on the second inner guide rail. A plurality of first outer slider assemblies are provided on the first outer guide rail. A plurality of second outer slider assemblies are provided on the second outer guide rail. It includes the following steps: Step S100: Install a first outer guide rail on the guide rail base, and install a first outer slider assembly on the first outer guide rail; Step S200: Using the first outer slider assembly as a reference, measure the radial runout and axial runout of the first inner guide rail using the first measuring frame, and adjust them until both the radial runout and axial runout are less than or equal to the threshold. Step S300: Using the first outer slider assembly as a reference, use the second measuring frame to measure the radial runout and axial runout of the second outer guide rail, and make adjustments until both the radial runout and axial runout are less than or equal to the threshold. Step S400: Install the second outer slider assembly on the second outer guide rail, and use the second outer slider assembly as a reference to measure the radial runout and axial runout of the second inner guide rail with the third measuring frame, and make adjustments until the radial runout and axial runout are both less than or equal to the threshold. Step S500: Install multiple first inner slider assemblies on the first inner guide rail and multiple first outer slider assemblies on the first outer guide rail; Step S600: Adjust the height of multiple first inner slider assemblies and multiple first outer slider assemblies to be equal; Step S700: Install multiple second inner slider assemblies on the second inner guide rail and multiple second outer slider assemblies on the second outer guide rail; Step S800: Adjust the height of multiple second inner slider assemblies and multiple second outer slider assemblies to be equal, and complete the installation.

[0006] Further, in step S200, using the first outer slider assembly as a reference, the radial runout and axial runout of the first inner guide rail are measured using the first measuring frame, and adjustments are made until both the radial runout and axial runout are less than or equal to the threshold. Specifically, this includes: Step S210: One end of the first measuring frame is fixed to the end face of the first outer slider assembly away from the first outer guide rail. The first measuring instrument and the second measuring instrument are installed on the other end of the first measuring frame. The measuring end of the first measuring instrument contacts the outer diameter of the first inner guide rail and is zeroed. The measuring end of the second measuring instrument contacts the end face of the first inner guide rail away from the guide rail base and is zeroed. Step S220: Drag the first outer slider assembly to move the first measuring frame, and observe the readings of the first measuring meter and the second measuring meter; Step S230: Continuously adjust the first inner guide rail by using a shim and ruler until the radial runout and axial runout of the first inner guide rail are both less than or equal to the threshold.

[0007] Further, in step S300, using the first outer slider assembly as a reference, the radial runout and axial runout of the second outer guide rail are measured using the second measuring frame, and adjustments are made until both the radial runout and axial runout are less than or equal to the threshold. Specifically, this includes: Step S310: One end of the second measuring frame is fixed to the first outer slider assembly, and a third measuring instrument and a fourth measuring instrument are installed on the other end of the second measuring frame. The measuring end of the third measuring instrument contacts the outer diameter of the second outer guide rail and is zeroed. The measuring end of the fourth measuring instrument contacts the end face of the second outer guide rail away from the guide rail base and is zeroed. Step S320: Drag the first outer slider assembly to move the second measuring frame, and observe the readings of the third and fourth measuring instruments; Step S330: Continuously adjust the second outer guide rail by using a shim and ruler until the radial runout and axial runout of the second outer guide rail are both less than or equal to the threshold.

[0008] Further, in step S400, a second outer slider assembly is installed on the second outer guide rail, and using the second outer slider assembly as a reference, the radial runout and axial runout of the second inner guide rail are measured using a third measuring frame, and adjustments are made until both the radial runout and axial runout are less than or equal to the threshold. Specifically, this includes: Step S410: Install the second outer slider assembly on the second outer guide rail; Step S420: One end of the third measuring frame is fixed to the second outer slider assembly. The fifth measuring instrument and the sixth measuring instrument are installed on the other end of the third measuring frame. The measuring end of the fifth measuring instrument contacts the outer diameter of the second inner guide rail and is zeroed. The measuring end of the sixth measuring instrument contacts the end face of the second inner guide rail away from the guide rail base and is zeroed. Step S430: Drag the second outer slider assembly to move the third measuring frame, and observe the readings of the fifth and sixth measuring gauges; Step S440: Continuously adjust the second inner guide rail using the shim gauge until the radial runout and axial runout of the second inner guide rail are both less than or equal to the threshold.

[0009] Furthermore, the threshold is 0.05 mm.

[0010] Further, step S600 includes detecting the height difference between the multiple first inner slider assemblies and the multiple first outer slider assemblies using a level, adjusting them to be at the same height, and correcting the first inner slider transition seat and / or the first outer slider transition seat.

[0011] Further, step S800 includes detecting the height difference between the multiple second inner slider assemblies and the multiple second outer slider assemblies using a level, adjusting them to be at the same height, correcting the second inner slider transition seat and / or the second outer slider transition seat, and completing the installation.

[0012] The beneficial effects of this invention are as follows: For ultra-large circular arc guide rail pairs, and for complex systems with double-layer guide rails and multiple slider assemblies on each guide rail, an overall installation scheme is proposed. This scheme allows for continuous adjustments during installation, ultimately ensuring the installation accuracy of the guide rail pairs. The steps are smoother, the measurement method is more reasonable, and repeated measurements and adjustments are avoided, thereby improving installation efficiency. Attached Figure Description
