Fluorine-containing plastic-coated guide rail mechanism

Abstract

The invention discloses a fluorine-containing plastic-coated guide rail mechanism, and particularly relates to the field of machine tool machining and manufacturing. The mechanism comprises a base, wherein a static guide rail is installed in a groove in the left side of the base through an inner hexagonal screw, an adjusting pin and a movable guide rail are clamped in a groove in the right side of the base, an elastic pressing plate is installed at the left end of the top face of the base, fluorine-containing guide rail soft belts are attached to the bottom ends of the static guide rail and the movable guide rail, a sliding base is slidably installed on the top faces of the static guide rail and the movable guide rail, oil scraping plates are installed at the two ends of the sliding base, and bottom wedges are installed at the two ends of the bottom face of the sliding base through screws. The fixed guide rail and the movable guide rail are used for jointly supporting the sliding base, meanwhile, the position of the movable guide rail is finely adjusted through an adjusting pin, and the friction coefficient between the sliding base and the guide rail can be changed, so that sliding damping is increased or reduced, the moving precision of the plastic-coated guide rail is improved, the unique guide rail structure of the plastic-coated guide rail is more convenient to disassemble and assemble, the maintenance convenience is greatly improved, and the installation and maintenance efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of machine tool processing and manufacturing, and more specifically, the invention is a fluorine-containing plastic-coated guide rail mechanism. Background technique [0002] The plastic-coated guide rail uses an adhesive to bond the PTFE guide rail soft tape to the guide rail surface, so that the friction form of the traditional guide rail becomes a cast iron-plastic friction pair. [0003] PTFE guide rail soft belt is based on PTFE, adding copper powder, molybdenum disulfide and graphite filler mixed and sintered to make a guide rail soft belt. The characteristics of PTFE guide rail soft belt are: wear-resistant Good performance, the dynamic and static friction coefficient is basically close, and the friction factor is very low, which can prevent low-speed crawling and make the movement stable. Since the soft belt material of the polytetrafluoroethylene plastic guide rail itself has a lubricating effect, t...

Problems solved by technology

[0004] The existing plastic-coated guide rails still have some shortcomings in actual use. For example, the traditional plastic-coated guide rails adopt constant sliding damping and constant friction coefficient. In high-precision machine tool processing, the traditional plastic-coated guide rails are not easy to move. control, it is not suitable for the processing of high-precision machine tools, and due to space problems, the stud bolts used cannot adopt relatively large specifications, resulting in insufficient fixing strength of the wedge, and one-way fixing is also easy to cause the deflection of the wedge and the The precision is not stable, and the wedge adjustment block needs to protrude to the outside of the sliding part in the fixing method of this structure, it is difficult to plan and install the oil scraping and dust removal parts, which makes the machine tool not resistant to dirt, and even easily causes machine failure
