  Analysis of linear motion accuracy of hydraulic coiling machine

  1) Select a reasonable type of tracking shape and rail combination.

  The shape of the machine guide rail is many, such as rectangular, triangular and dovetail, etc. From the combination of the guide rail and the guide rail, a double rectangle, a double triangle or a combination of a rectangle and a triangle can be used.

  2) Improve the manufacturing precision of the guide plate of the coiling machine.

  As far as possible, improving the machining accuracy of the guide rail and matching the contact precision is the key to improving the accuracy of the linear soil movement. Therefore, when using the guide rail grinding machine to guide the worktable guide rail, it is necessary to improve the precision of the grinding. The precision of the machine guide rail is often used for scraping. And other methods of processing.

  3) Use static pressure rail or plastic rail.

  The structure of the hydrostatic guide rail is such that there is a laminated I oil between the worktable and the bed rail, which can equalize the straightness error of the guide rail surface and prevent the wear of the guide rail, thereby improving the linear freight rate.

  The Yan plastic-plastic guide rail is made of PTFE plastic guide rail soft belt and is fixed on the guide rail surface with adhesive. This kind of guide rail can be lubricated and lubricated. Because its dynamic and static friction coefficients are similar, the crawling phenomenon can be eliminated. The positioning accuracy is high, and the plastic guide mushroom has small damage, which can improve the precision of the machine tool.
