Description

Technical Field

[0001] The invention relates to the technical field of linear guide rails, and in particular to a spliced ​​false rail for a linear guide rail. Background Art

[0002] There are many types of sliders with various structures. According to the rolling element type, they include ball type and roller type. According to the groove type, they include arc groove, Gothic groove and plane groove. According to the contact structure, they include DF structure, DB structure and double Gothic groove. According to the external dimensions, they include long and short sliders, wide and narrow sliders, high and low sliders and multi-groove sliders.

[0003] Patent TWI263001B discloses a combined clamping rail for a linear slide rail, where the clamping rail units can be spliced ​​in the length direction. However, the structure of the clamping rail unit is limited to only adapt to one type of linear slide rail, and cannot adapt to different types of linear slide rails.

[0004] Patent CN210859558U discloses a clamping rail, which can adapt to face-to-face (DF) and back-to-back (DB) linear slides by setting retaining surfaces with different orientations and spacings on the clamping rail. However, once the clamping rail is manufactured, its size is fixed and it can only adapt to linear slides of corresponding sizes. When the opposite length, width, height, number of raceways, and contact structures of the slider are different, the clamping rail cannot be adapted and the slider of the corresponding size needs to be re-customized.

[0005] Patent CN218718212U discloses a combined clamping rail of a linear slide and a slider device having the combined clamping rail, wherein a second clamping rail that can be spliced ​​is arranged in the first clamping rail to raise the height of the first clamping rail. However, the second clamping rail does not need to be adapted to the slider, but only serves to raise the height.

[0006] Since the slider of the linear guide rail may malfunction during use, the customer may need to replace a single slider or several sliders. However, the dummy rails manufactured by the manufacturer are often integral dummy rails that are compatible with the entire set of linear guide rails. It is impossible to re-mold and manufacture a single dummy rail just because individual sliders need to be replaced. This results in huge waste in later maintenance and replacement.

[0007] The dummy rail is assembled on the slider and keeps the rolling element from falling off until the slider is installed on the track body. There are many types of sliders, such as different lengths, widths, heights, numbers of raceways, and contact structures. As a result, the dummy rail needs to be made into various shapes according to the different types of sliders, making it difficult to achieve interchangeability of the dummy rails, requiring a large number of molds, and increasing mold costs and management costs. Summary of the invention

[0008] The technical problem to be solved by the present invention is: in order to solve the technical problem that the dummy rail in the prior art cannot adapt to different types of sliders, the present invention provides a splicing dummy rail for a linear guide rail, which can adapt to different types of sliders through splicing, thereby reducing the number of manufacturing molds and reducing costs.

[0009] The technical solution adopted by the present invention to solve its technical problem is: a spliced ​​dummy rail for a linear guide rail, which is used for a movable setting of a slider, the slider includes multiple rolling bodies, and the spliced ​​dummy rail includes at least one dummy rail unit; the dummy rail unit includes a component A, and the component A includes a supporting part and a splicing part. The multiple components A are connected by the splicing part, and the supporting part of each component A is in contact with the rolling body.

[0010] Furthermore, in order to adapt to sliders of different heights and widths, the splicing portion includes a height splicing portion and a width splicing portion, and the components A are detachably connected to each other via the height splicing portion and / or the width splicing portion.

[0011] Further, in order to adapt the DB structure slider and the DF structure slider, the support parts of the components A adjacent to each other in the height direction are arranged opposite to each other or facing each other, and the support parts of the components A adjacent to each other in the width direction are arranged facing each other.

[0012] Furthermore, in order to enable the dummy rail unit to form a spliced ​​dummy rail of different lengths according to length requirements, the splicing portion further includes a length splicing portion, and the components A are detachably connected to each other via the length splicing portion.

[0013] Furthermore, in order to effectively support the rolling body, the support portion is tangent to the rolling body, and the support portion is inclined with respect to the horizontal plane to support the rolling body.

[0014] Furthermore, in order to ensure the supporting effect, the angle between the supporting portion and the horizontal direction is 45°±3°.

[0015] Furthermore, the rolling body is a ball or a roller.

[0016] Furthermore, in order to further improve the versatility of the dummy rail, the dummy rail unit also includes a component B having a splicing portion, the splicing portion includes a width splicing portion and a height splicing portion, and any component B is detachably connected to component A and other components B through the width splicing portion and / or the height splicing portion.

[0017] Furthermore, in order to satisfy the requirement that the components B can be spliced ​​in the length direction, the components B also include a length splicing portion, and the components B are detachably connected to each other through the length splicing portion.

[0018] Furthermore, in order to realize the rapid splicing of component A and component B, the splicing portion is a splicing column and a splicing hole provided on the corresponding surfaces of component A and component B.

[0019] Furthermore, in order to provide a splicing margin, an elastic member is provided between the engaging column and the engaging hole connected thereto.

[0020] Furthermore, in order to provide a splicing margin, the component A and the component B are made of elastic material.

[0021] Furthermore, the slider is a DB structure slider, a DF structure slider and a roller type slider.

[0022] Furthermore, the slider has two channels, four channels, six channels or eight channels.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The spliced ​​dummy rail for the linear guide rail of the present invention is formed by splicing component A and component B in the width direction, height direction and length direction to form a dummy rail unit, which can adapt to sliders with different widths, heights, numbers of raceways and contact structures.

[0025] The linear guide rail of the present invention uses a spliced ​​dummy rail, and the components A and B are similar to standard parts.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0040] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] A spliced ​​false rail for a linear guide rail is used for movable arrangement of a slider, wherein the slider comprises a plurality of rolling bodies 2.

[0043] The spliced ​​dummy rail includes at least one dummy rail unit; the dummy rail unit includes a component A, and the component A includes a support portion a4 and a splicing portion. Multiple components A are connected by the splicing portion, and the support portion a4 of each component A is in contact with the rolling body 2.

[0044] The upper and lower surfaces of component A are the height splicing degree a1, and the right side surface is the width splicing part a2, so that multiple components A can be spliced ​​in the width and height directions to form a false rail unit.

[0045] The front and rear surfaces of the component A are length joints a3, through which the dummy rail unit can be assembled into a spliced ​​dummy rail in the length direction.

[0046] The support portion a4 of the component A is an inclined surface and is in tangential contact with the rolling element 2. Especially for a slider using a ball as the rolling element 2, the support portion a4 with an inclined plane can also provide good support for the ball, and the ball will not slide off the slideway. The preferred angle between the support portion a4 and the horizontal plane is 45°±3°. The inclined support portion a4 will provide a force perpendicular to the support portion a4 to the ball, pushing the ball into the slideway.

[0047] The support portion a4 does not need to be configured as an arc surface that cooperates with the ball as in the prior art. The planar support portion a4 can greatly reduce the manufacturing cost and can be adapted to both the roller and the ball.

[0048] According to the type of the slider, the preferred component A adopts a trapezoidal structure, and a spliced ​​false rail adapted to the slider can be formed only by the component A. The specific splicing method is detailed in the following embodiments.

[0049] In order to meet the needs of various types of sliders, component B can be added for splicing to form a more versatile false rail unit.

[0050] Component B also includes a height splicing portion b1, a width splicing portion b2 and a length splicing portion b3. Component B can be spliced ​​with component A, and components B can also be spliced ​​with each other. Component B is a rectangular parallelepiped structure. According to the type of the slider, components A and B can be reasonably selected and spliced ​​to form a splicing type false rail adapted to the slider. The specific splicing method is detailed in the following embodiments.

[0051] The above-mentioned joint parts all adopt the structure of joint columns and joint holes, and can be quickly joined by simple insertion, thereby improving assembly efficiency.

[0052] Component A and component B are made of elastic materials. 70% to 90% of thermoplastic polyester elastomer (TPEE) and 30% to 10% of thermoplastic polyester resin (PBT) are selected. PBT ensures the mechanical strength and rigidity of the dummy rail. TPEE ensures that the dummy rail has elastic rebound ability and provides a splicing margin for the slider. Since different types of sliders may have slight size differences, using components A and B with a certain elastic deformation ability can compensate for the impact of the size difference and provide a splicing margin for the slider.

[0053] Similarly, for sliders of special sizes customized by a very small number of customers, an elastic member is provided between the coupling column and the coupling hole connected thereto, and the elastic deformation of the elastic member can also provide a splicing margin for the slider.

[0054] Embodiment 1, as Figure 4 As shown, a dummy rail is constructed for a four-channel slider of a standard DF structure. Four components A are assembled through a height joint a1 and a width joint a2, and the support parts a4 of the components A on the same side are arranged opposite to each other, with the support part a4 of the upper component A facing upward and the support part a4 of the lower component A facing downward, thereby forming a single dummy rail unit. Then, according to the length of the slider, multiple dummy rail units are assembled into a spliced ​​dummy rail through a length joint, and the slider is assembled onto the spliced ​​dummy rail, so that the four balls of the slider are supported by the corresponding support part a4 of the component A.

[0055] Embodiment 2, as Figure 5 As shown, a dummy rail is built for a high-assembly DF structure four-channel slider. Compared with a standard DF structure four-channel slider, the high-assembly DF structure four-channel slider mainly has a larger spacing between the balls in the height direction. Therefore, 4 components A and 2 components B are selected, and component B is spliced ​​between components A in the height direction to form a single dummy rail unit. Then, according to the length of the slider, multiple dummy rail units are assembled into a spliced ​​dummy rail in the length direction, and the slider is assembled to the spliced ​​dummy rail, so that the four balls of the slider are supported by the corresponding support part a4 of component A, and component B can raise the distance between components A that support the balls.

[0056] Embodiment 3, as Figure 6 As shown, a dummy rail is built for a wide DF structure four-channel slider. Compared with a standard DF structure four-channel slider, the high-assembly DF structure four-channel slider mainly has a larger spacing between the balls in the width direction. Therefore, 4 components A and 2 components B are selected, and component B is spliced ​​between components A in the width direction to form a single dummy rail unit. Then, according to the length of the slider, multiple dummy rail units are assembled into a spliced ​​dummy rail in the length direction, and the slider is assembled to the spliced ​​dummy rail, so that the four balls of the slider are supported by the corresponding support part a4 of component A, and component B can widen the distance between components A that support the balls.

[0057] Embodiment 4, as Figure 7 As shown, a four-channel slider is used to construct a fake rail for DB. Four components A and four components B are selected, and the support parts a4 of the components A on the same side are arranged opposite to each other in a splicing manner, and two components B are spliced ​​between two components A in the height direction to form a single fake rail unit. Then, according to the length of the slider, multiple fake rail units are assembled into a spliced ​​fake rail in the length direction, and the slider is assembled on the spliced ​​fake rail, so that the four balls of the slider are supported by the corresponding support parts a4 of the components A, and the components B can raise the distance between the components A supporting the balls.

[0058] In addition, there are other DF structural sliders and DB structural sliders of different widths and heights, and component B can be selectively spliced ​​in the height and width directions according to specific sizes, which will not be exhaustively described here.

[0059] Embodiment 5, as Figure 8 As shown, a dummy rail is built for two Gothic channel sliders. Four components A are selected and the support parts a4 of the components A on the same side are arranged oppositely to form a single dummy rail unit. Then, according to the length of the slider, multiple dummy rail units are assembled into a spliced ​​dummy rail in the length direction, and the slider is assembled on the spliced ​​dummy rail so that the four balls of the slider are supported by the corresponding support parts a4 of the components A.

[0060] Embodiment 6, as Fig. 9 As shown, a dummy rail is constructed for four German channel sliders. Eight components A are selected and divided into two groups. Two groups of dummy rail units are formed according to the construction method of Example 5, and each group of dummy rail units supports two balls. Then they are spliced ​​in the length direction to form a spliced ​​dummy rail.

[0061] In addition, the construction methods of the six-German groove sliders and the eight-German groove sliders are similar, and are not illustrated or described in detail here.

[0062] Embodiment 7, as Fig.10 As shown, a dummy rail is constructed for a roller type slider. The construction form of the dummy rail is the same as that of embodiment 1.

[0063] In addition, the construction method of roller-type sliders of different widths and heights is the same as the construction method of ball-type sliders, and will not be exhaustively described here.

[0064] The standard DF structure four-channel slider is a standard part, with the width distance of the slider channel as the reference width, and the height distance of the slider channel as the reference height. The channel width of the wide-width slider is 1.5 times and 2 times the channel width of the standard slider. The height of the high-group slider is 1.15 times the height of the standard slider, and the DB-type channel height spacing is also 1.15 times that of the DF type. Therefore, the width of component A is 0.5 times the reference width, and the height of component A is 0.5 times the reference height. The width of component B is 0.5 times the reference width, and the height of component B is 0.15 times the reference height, so that it can adapt to other sliders of different types, widths and heights. Therefore, components A and B are similar to standard parts and can form a pseudo rail that is similar to standardized.

[0065] By adopting the above-mentioned dummy rail unit, splicing can be performed according to the number and type of adapted sliders. A single slider or several sliders can be spliced ​​through the dummy rail unit to form spliced ​​dummy rails of different lengths, which greatly reduces the production cost.

[0066] In summary, the spliced ​​dummy rail for the linear guide rail of the present invention can be adapted to different types of sliders by splicing, thereby reducing the number of manufacturing molds and lowering costs.

[0067] The above description is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
