Abstract

The present invention relates to a rail structure of a linear guide rail and a covering band therefor. The covering band covers up the guide rail which has a guiding surface. On each of two lateral sides of the guiding surface a fastening portion with a thickness is disposed. The covering band comprises a capping surface covering the guiding surface and at least two consecutive bent segments extending from the capping surface in a direction towards the fastening portion. A fastening recess is formed with the capping surface and the bent segments, for tightly engaging the fastening portion. Thereby the vertical combining strength of the joined covering band and guide rail is enhanced.

Description

Track structure of linear slide and its cover tape

The invention relates to a track structure of a linear slide rail and a cover belt thereof, in particular to a buckle portion having a buckled groove to be fastened to the two sides of the slide rail, and the buckle gap has a fastening gap. The fastening gap is equal to the thickness of the fastening portion, and the joint rigidity of the cover tape and the slide rail in the upper and lower directions can be improved.

When the linear slide rail is used, a plurality of bolt holes are generally arranged along the axial direction on the slide rail, and the slide rail is fixed on the working platform by bolts. In actual use, dust or oil stains often accumulate in the bolt holes, so that when the sliding body rigid body runs through the bolt hole position, dust and dirt enter the sliding body body, hindering the rolling of the rolling bodies in the sliding body body, resulting in rolling The sliding body rigid body does not run smoothly. Therefore, in order to avoid this phenomenon, it is common to cover the bolt holes with a hole cover or a cover tape to prevent the bolt holes from being contaminated with dust or oil.

Wherein, the use of the hole cover to cover the bolt hole is more troublesome than the need to insert the hole cover into the bolt hole in sequence, and the hole cover is plugged in the bolt hole, which may not easily maintain the surface of the sliding rail due to machining tolerance, and still The accumulation of dust and dirt; or the force exerted on the hole cover when the sliding body is running, the hole cover will sink and form a lack of grooves to accumulate dust and dirt.

The cover tape is a long-shaped sheet-like body that covers the surface of the slide rail with a cover tape to solve the defect caused by the use of the hole cover.

One of the combination of the cover tape and the slide rail is, for example, US Patent No. 20090257692 "Guide rail with a cover strip for a linear bearing", US Patent No. 6,749,338 "Arrangement of a cover band on a linear guide", German patent 19919247 "Guide rail for linear bearing, with two insertion grooves running longitudinally to connect to longitudinal groove" or PCT Patent No. 0133090 "Guide rail for a linear bearing" and the like. The utility model adopts an elongated notch on the surface of the sliding rail, and the covering tape has an elastically deformable latching portion, and the covering strip covers the elongated notch on the surface of the sliding rail, so that the elastically deformable latching portion is elastically deformed. The cassette is on the inner surface of the elongated slot and the surface of the cover strip is flush with the upper surface of the slide rail.

Also, the Republic of China Patent No. 201139880, "The Cover for Sports Guides and Motion Guides", US Patent No. 5622433, "Top cover along with a track rail unit and guide unit on which it is equipped", German Patent No. No. 10032473 "Guide rail for linear bearing has cover belt composed of two angle-edged sheet strips" or German Patent No. 2,952,290, "Anordnung zum Verschliessen von Bohrungen in einer Führungsschiene" and the like. A counterbore is provided on the slide rail, and an insert is disposed under the cover tape, and the cover tape is elastically deformed into the counterbore of the slide rail by the insert to fix the cover tape on the slide rail.

In the foregoing two methods, since the latching portion or the embedding portion of the cover tape has been deformed in the inner surface of the elongated slot or the counterbore, it is difficult to remove the repair and replacement; and the cover tape only uses the elastic support card, so The joint rigidity in the upper and lower directions of the vertical slide rail is poor, and the cover belt may be shaken and unstable.

There are also US Patent No. 5,575, 566, "Linear motion guide cover band", US Patent No. RE42885 "Linear guide device" or US Patent No. 6,592,261 "Motion guide device". The elastic covering members are provided on both sides of the covering tape, and the covering tape is fixed on the sliding rail by the elastic clamping members being clamped on both sides of the sliding rail. In this way, the elastic support is used, and there is a lack of rigidity in the upper and lower directions of the vertical slide rail. In addition, when the cover tape of the above-mentioned front case is clamped on both sides of the slide rail, the width of the cover belt is smaller than that of the slide rail. The width of the two sides is slightly wider, so when the sliding body rigid body is placed on the sliding rail, the covering tape may affect the smoothness of the rigid body running of the sliding seat; and the elastic clamping member end of the above-mentioned front cover tape is exposed, and because of the machining Factor, the end of the elastic grip of the cover tape may have sharp points, which may cause scratches when exposed.
