Definitions

  • the invention relates to a guide rail for a linear bearing with a plurality of through openings arranged one behind the other in the longitudinal direction of the rail and extending from the top of the rail for receiving fastening elements, with a longitudinal groove open to the top of the rail and extending over the length of the guide rail, and with a longitudinal groove and the through openings outwardly covering closure body, which is partially or completely inserted into the longitudinal groove, wherein it is pressed into the guide rail under elastic deformation and is fastened there due to its restoring spring force.
  • Guide rails are used on machine tools and must be replaced as wear parts from time to time. Therefore, they are often attached to the machine frame with screws.
  • a cover band is used to close the bores for the screws as a closure body, which covers the entire width of the guide rail when pressed into the longitudinal groove of the guide rail bulges. Due to its return spring force, the masking tape claws into the side surfaces of the longitudinal groove, so that it is held in the groove along two contact lines. The space of the through openings is closed to the outside along these lines of contact.
  • the cover band does not have flat sealing surfaces for the front seals of a guide carriage which can be moved along the guide rail, which can have a disadvantageous effect on the seal.
  • a guide rail is known in which a cover plate, which (forming a flat Dichtf kiee, rests with the angled edge portions within a longitudinal groove of the guide rail on the inclined side surfaces. This results in an arrangement of the shroud relative to the guide rail as with a dovetail guide, but when installing the cover plate, it must be inserted from one end into the guide rail in the longitudinal direction of the rail.
  • the published patent application DE 195 24 810 A1 shows and describes an arrangement for closing bores in a guide rail, in which two projecting resilient retaining strips for attachment are formed on a cover band used as a closure body and rest against the edges within a longitudinal groove of the guide rail , These are located on two inclined webs, which are formed by milling out the guide rail. The retaining strips can be pushed into the resulting dovetail profile of the longitudinal groove when installing the cover tape. As a result of the two inclined webs, however, there is a disadvantageous production of the guide rail.
  • the invention is based on the object of providing a simply constructed guide rail with a flat sealing surface for the front seals of a guide carriage, which enables the closure body to be mounted easily.
  • the closure body consists of an outer cover band and in relation to the guide rail an inner clamping band fastened thereon is formed, which has clamping regions and spacers arranged between the cover band and the clamping regions.
  • the clamping band deforms when the closure body is pressed in and claws firmly in the longitudinal groove.
  • the effect of the resulting deformation is compensated for by the spacer and is therefore not passed on to the masking tape. Therefore, the masking tape does not bulge.
  • the clamping band can be made in one piece with the clamping areas and the spacers. Spacers which extend continuously in the longitudinal direction and spacers in several individual sections can be formed on the clamping band and connected to the cover band. The fact that a plurality of individual spacers are formed one behind the other on a clamping band means that it can be rolled.
  • the masking tape and the clamping tape can be glued or welded together, for example.
  • the guide rail can have two insertion grooves running in the longitudinal direction, each adjoining the longitudinal groove, into which the clamping areas of the clamping band are pressed.
  • the longitudinal groove in the guide rail can be designed such that it has shoulders on its long sides.
  • the masking tape can be arranged on the guide rail with edge regions lying on the top of the rail. But it is also possible that Insert the closure body into the guide rail so that the cover strip forms a common, flat outer surface with the top of the rail.
  • Embodiments of the invention are shown in the drawing in comparison with a previously known guide rail, which is described in more detail below. Show it:
  • Figure 1 is an end view of a closure body for a guide rail according to the invention
  • Figure 2 shows the cross section of a guide rail, in which the closure body according to Figure 1 is partially inserted;
  • Figure 3 shows a further closure body in an end view
  • FIG. 4 shows a representation corresponding to FIG. 2 with the further closure body
  • Figure 5 shows the cross section of a guide rail, in which a closure body is fully inserted in a third embodiment
  • FIG. 6 shows a perspective view of the clamping band of the closure body according to FIG. 5;
  • FIG. 7 shows the cross section of a guide rail into which a closure body is completely inserted in a fourth embodiment
  • Figure 8 is a perspective view of a longitudinal portion of a previously known guide rail, the longitudinal groove of which is rectangular in cross section, with an end face cut in the region of a through opening;
  • FIG. 9 shows an enlarged section of the end face according to encirclement IX of FIG. 8;
  • FIG. 10 shows a cross section through the guide rail according to FIG. 8.
  • a cover band 1 which consists of a resilient band material, for example a steel sheet, is inserted in a longitudinal groove 2 of the guide rail 5.
  • the longitudinal groove starts from the upper side 3 of the rail and has a somewhat smaller width than the cover strip 1. This therefore had to bulge out towards the guide rail 5 when it was pressed into the longitudinal groove.
  • a cover band 7 shown in FIGS. 1 and 2 for a guide rail 5 according to the invention is fixedly connected to a gill band 8, which lies on the surface of the cover band 7 which faces the interior of the guide rail 5.
  • This clamping band 8 is provided at its longitudinal ends with two bent spacers 9, which in turn merge into clamping regions 10, namely clamping legs 10, which are bent towards the inside of the guide rail 5.
  • the guide rail 5 is provided on its upper side with a central longitudinal groove 11 which serves to hold the clamping band 8.
  • two insertion grooves 12 are additionally machined into the guide rail 5, which correspond to the position of the clamping legs 10 and the spacers 9 and start from the longitudinal groove 11.
  • the clamping legs 10 have a slightly larger length. They therefore bend resiliently when the cover strip 7 with the clamping strip 8 is pressed into the longitudinal groove 11 and the insertion grooves 12 of the guide rail 5.
  • the clamping legs 10 grip the guide rail 5 and thus hold the cover band 7, which rests with its edge regions on the top side 3 of the rail, in its position.
  • the spacers 9 on the clamping band 8 are bent at right angles. However, they can also be set slightly laterally, for example forming an angle with the region of the clamping band 8 which is in contact with the cover band 7 and deviates by 5 ° from the right angle. This makes it easier to assemble.
  • the embodiment of the closure body shown in FIGS. 3 and 4 differs from this embodiment in that the clamping band 13 fastened to the cover band 7, with its spacers 9 bent at right angles, has clamping legs 14 which are bent at right angles to the outside of the guide rail 5.
  • the longitudinal groove 15 of the guide rail 5 is made deeper so that the spacers 9 are not laterally guided and can dodge to the inside of the guide rail 5 if the cover band 7 with the clamping band 13 is pressed into the longitudinal groove 15 until the clamping band 7 on the top of the rail 3 is present.
  • the clamping limbs 14 grip the outer boundary walls of the longitudinal groove 15 of the guide rail 5.
  • a clamping band 16 with clamping legs 17 in the form of a sheet metal strip is designed for a guide rail 5 according to the invention, on which spacers 18 arranged one after the other at intervals along the longitudinal center line are formed. These are attached to the inner surface of the cover strip with respect to the guide rail 5. With its outer surface, the cover band 7 forms, together with the top side of the rail 3, a flat contact surface for the front seals of the guide carriage to be used.
  • the longitudinal groove 19 of the guide rail 5 is designed with steps. Thus, it has an area with a slightly smaller width than the width of the clamping band 16, so that the clamping legs 17 grip the guide rail 5 here. Below that are paragraphs 20 which limit the depth of insertion of the closure body. Over the area with the shoulders 20, the longitudinal groove 19 has an area of even greater width, in which the cover band 7 is accommodated.
  • FIG. 7 An embodiment similar to this embodiment is shown in FIG. 7.
  • the closure body inserted into the longitudinal groove 19 of the guide rail 5 differs only in the embodiment of its clamping band 21, which is designed with its clamping legs 22 and at least one spacer 23 as a one-piece bent sheet metal part.
