3 axis painting manipulator we manufacture, three axis parts are installed around the linear guide in Taiwan silver by the beam, the linear guide 1500, on a series of bolt spacing 100 counterbore, connected by six angle bolts and frame. On the linear guide hole due to the relatively dense, a hole painting is the main line we tapped due to the quality of the reasons often centredistanceofhole difficult to ensure that the mounting rails around there are parallel degree error guide to sports bad, want to ask Master is similar to the structure is how to deal with.
Your rail installation is not correct, huh? Screw hole assembly, fitter, have nothing to do with it. If you don't even have a baseline, it's a waste of the linear guide. This is not the most important relationship with the screw hole position. It is important to install the mounting surface of the linear guide rail. The bottom of the rail must be machined with straightness, and then a side must have a datum plane, which can be used as a benchmark for either the inside or the outside of the two rail. The machining must be done directly with a planer and a guide rail. When installing, tighten the screw slightly first, then the other side of the benchmark is compressed with several wedges, which may be troublesome if you use a shelf with a head screw. The guide block connected with the upper slide plate also has the same positioning principle, but only one rail, the slider above needs to be positioned (Ji Zhun), and the other side can not be positioned. If the accuracy requirements are high, you must also use the wire table to adjust the screws on the guide rail one by one.
Upstairs said yes, your rail installation in the face of wrong ah? If you don't even have a baseline, it's a waste of the linear guide. This is not the most important relationship with the screw hole position. It is important to install the mounting surface of the linear guide rail. The bottom of the rail must be machined with straightness, and then a side must have a datum plane, which can be used as a benchmark for either the inside or the outside of the two rail. But in the assembly, they can not do the benchmark, the first step is to measure the verticality of the bottom surface of the guide rail straightness and the bottom surface and the side of the rail, and leading after the installation, and side gauge parallelism and two gauge high (parallel horizontal), how do you measure?
I think you used in the manipulator, so I think, installation of precision linear guide should not be very high, so as long as the installation process can be a good (one installation, there is the backing surface, like precision is not high, the general grinding machine directly grinding can be, if you need some high precision tooling, gauge). There is a mounting hole you said from the partial problems, I suggest that you first will put in the linear guide installation, on the side surface and make the firm Hill, both ends and the middle three screws and screw drill press block, then the three screw and three screw pressing block, finally the linear guide rail installed in three, screw holes have hit on the screw, three pieces of pressing block also tightened, and make the other hole, finally screw holes can be! If it doesn't work, you can hit the hole in the CNC milling machine or digital display milling machine, and finally hit it by drilling machine!
The accuracy of the mounting surface of the rolling linear guide rail requires the mounting surface of a single rail pair, and its plane accuracy can be slightly lower than the running accuracy of the guide rail pair. When two or more rail pairs are used in the same plane. This is a total, everything is based on this operation, and the following details, you can see the information I give you I.
