Description

Technical Field

[0001] The invention relates to the field of rolling guide rails, in particular to a rolling composite slide rail. Background Art

[0002] Rolling guides are widely used. As prefabricated guide rail components, they can be easily installed and used as long as the installation surface is processed on the base. However, in use, high-speed reciprocating motion often causes the guide rail to heat up. In particular, since the slide rail is long, the temperature changes, which has a greater impact on the entire length, while the temperature change of the base is small. This will cause inconsistent thermal expansion length and form internal stress. Without considering the heat generated by movement friction, the thermal expansion coefficient and thermal conductivity of the slide rail and the base should be as consistent as possible. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a rolling composite slide rail, which can effectively solve the deficiencies in the prior art.

[0004] The present invention is realized through the following technical scheme: it is composed of a plurality of short slide rail seats and at least two long slide rails, the short slide rail seats are provided with mounting surfaces and mounting holes, and long slide rail positioning stoppers, the short slide rail seats are arranged in a straight line, the long slide rails are provided with stoppers and roller raceways that match the short slide rail seats, the length of the long slide rail is the full length of the guide rail, the stoppers on the short slide rail seats and the long slide rails are abutted against each other, and the long slide rails are positioned in directions other than the length direction.

[0005] As a preferred technical solution: the positioning stop can be a double inclined surface relative to the seat surface or an I-shaped stop parallel to the bottom surface and perpendicular to the bottom surface.

[0006] As a preferred technical solution: elastic force is used to press the positioning stoppers between the long slide rails to make them fit together.

[0007] As a preferred technical solution: the short slide rail seat can be divided into two separate groups on the left and right, with a group of long slide rail positioning stops on each side.

[0008] The beneficial effects of the present invention are as follows: the present invention is composed of a plurality of short slide rail seats and at least two long slide rails; the short slide rail seats can be installed on a base in sections, and have stoppers fitted with the long slide rails, for limiting the displacement of the long slide rails except in the length direction; there are gaps between the short slide rail seats, serving as expansion joints; the long slide rails have stoppers fitted with the short slide rail seats and raceways for roller rolling, and can freely expand and contract relative to the short slide rail seats and the base in the length direction, thereby eliminating thermal stress, and can be used for bases such as natural stone with good thermal stability.

[0021] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0022] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0023] In the description of the present invention, it is necessary to understand that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end" and the like indicate orientations or positional relationships based on the orientations 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.

[0024] In addition, in the description of the present invention, “plurality” means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0025] Terms such as "upper", "above", "lower", "below", etc. used in the present invention to indicate spatial relative positions are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. Terms of spatial relative position may be intended to include different orientations of the device in use or operation in addition to the orientation shown in the drawings. For example, if the device in the figure is turned over, the unit described as being "below" or "beneath" other units or features will be located "above" the other units or features. Therefore, the exemplary term "below" can encompass both the above and below orientations. The device may be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptors used herein interpreted accordingly.

[0026] In the present invention, unless otherwise clearly specified and limited, the terms "disposed", "socketed", "connected", "through", "plugged" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Example 1

[0028] like Figure 1 As shown, there are several double-bevel stopper slide rail short seats 1 arranged in a straight line. Figure 6 As shown, a bottom surface 1002 and two side surfaces 1003 adjacent to the bottom surface can be used as mounting surfaces and installed on a base. There are double-bevel stoppers 1001 on the left and right sides of the middle to cooperate with the long slide rails 2. The length of the two long slide rails 2 is the full length of the roller guide rail. There are double bevels that cooperate with the double bevels on the double-bevel stopper slide rail short seat 1. Opposite to it is a ball roller groove for the ball roller 3 to roll. On the outside of the roller are the rolling guide slider and the ball circulation mechanism (not shown in the figure). The ball raceway on the slider is smaller than the actual size, so that the slider exerts pressure on the roller toward the middle. There are expansion joints 9 for thermal expansion and contraction between each section of the double-bevel stopper slide rail short seat 1, which is used for a rolling guide rail that cooperates with a natural granite base. The length of each section of the slide rail short seat is 100mm, leaving a gap of 0.1mm in the middle. When the operating ambient temperature is 30°C higher than the assembly ambient temperature, the elongation of each section of the slide rail short seat is approximately 0.03mm, and a gap of 0.1mm is sufficient.

[0029] Example 2

[0030] The difference from the first embodiment is that the roller is a cylindrical roller 4, such as Figure 2 As shown, the difference between the double-bevel stop cylindrical roller guide rail 201 and the long guide rail 2 is that there is a flat and inclined raceway with cylindrical rollers 4 on the outside.

[0031] Example 3

[0032] Unlike Example 1 and Example 2, Figure 3 As shown, the stop between the I-shaped stop rail short seat 101 and the I-shaped stop ball roller rail 202 is an I-shaped stop, and the three I-shaped stop surfaces 1004 on the I-shaped stop rail short seat 101 cooperate with the stop surface of the I-shaped stop ball roller rail 202. Figure 4 The figure shows the I-shaped stop surface on the I-shaped stop rail short seat 101, which cooperates with the I-shaped stop cylindrical roller rail 203, and has a cylindrical roller 4 on the outside.

[0033] Example 4

[0034] Different from Example 3, Figure 5 As shown, the stop size of the I-shaped stop rail short seat 101 is larger than the stop size of the I-shaped stop cylindrical roller rail 203, and the gap between the two is supported by an elastic member 7 to press the I-shaped stop cylindrical roller rail 203 to one side of the stop.

[0035] Example 5

[0036] Different from Example 3, Figure 7 and Figure 8 As shown, Figure 7 There are holes and countersunk holes on the double-sided double-bevel stop ball roller with screw compression slide 204, and the corresponding double-bevel stop slide short seat 1 also has a through hole. There are long studs 5, nuts 6 and elastic parts 7 to elastically compress the double-sided double-bevel stop ball roller with screw compression slide 204 on both sides onto the stops on both sides of the double-bevel stop slide short seat 1.

[0037] Figure 8 and Figure 7 Similarly, a single-sided short screw 8 and an elastic member 7 elastically press the I-shaped stop ball roller with screw compression rail 205 into the I-shaped stop of the I-shaped stop rail short seat 101. Due to the elastic force, the long rail 2 is pressed toward the rail short seat, and the outer slider and the rail roller can be arbitrarily set to a pre-tightened or clearance state.

[0038] Example 6

[0039] Different from the above embodiments, Fig. 9 As shown, the short slide rail seat can be configured as two groups of separated short slide rail seats 102 separated on the left and right sides, so that the distance between the long slide rails 2 on both sides becomes longer, and a group of long slide rails 2 plus a slider can be used independently.

[0040] The beneficial effects of the present invention are as follows: the present invention is composed of a plurality of short slide rail seats and at least two long slide rails; the short slide rail seats can be installed on a base in sections, and have stoppers fitted with the long slide rails, for limiting the displacement of the long slide rails except in the length direction; there are gaps between the short slide rail seats, serving as expansion joints; the long slide rails have stoppers fitted with the short slide rail seats and raceways for roller rolling, and can freely expand and contract relative to the short slide rail seats and the base in the length direction, thereby eliminating thermal stress, and can be used for bases such as natural stone with good thermal stability.

[0041] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
