Description

Technical Field

[0001] The invention relates to the field of linear guide rail installation, in particular to increasing installation datums for four-row ball linear guide rails. Background Art

[0002] During the installation of linear guide rails, force leveling blocks are usually used on the left and right sides of the guide rails to accurately position the left and right sides of the guide rails. However, for guide rails with limited installation conditions, especially guide rails that cannot be installed with force leveling blocks, smaller positioning equipment is needed to assist in the positioning and installation of the guide rails. The offset of the guide rails can also be accurately adjusted during the positioning and installation. However, the existing force leveling blocks cannot meet the installation positioning method under such special circumstances.

[0003] Therefore, we propose a four-row ball linear guide with an additional mounting base to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a four-row ball linear guide with an increased installation reference to solve the problems raised in the above-mentioned background technology. The technical solution of the present invention provides a solution that is significantly different from the prior art in order to solve the technical problem that the prior art solution is too single.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The four-row ball linear guide rail increases the installation reference, including a slide rail and a mounting seat. Needle gauges are installed at the bottom of both sides of the slide rail, and conical bolts are installed on the surface of the mounting seat. The side surfaces of the conical bolts fit the needle gauges.

[0007] In a further embodiment, the bottom edges of both sides of the slide rail are provided with bevel chamfers, and the needle gauge is simultaneously fitted with the bevel chamfers and the bevel of the conical bolt.

[0008] In a further embodiment, a recessed layer is provided on the surface of the needle gauge, and the conical bolt is in contact with the recessed layer and is located at the lowest point of the recessed layer.

[0009] In a further embodiment, the conical bolt comprises a conical outer sleeve and an inner bolt, the conical outer sleeve is sleeved on the outer side of the inner bolt, and the conical outer sleeve and the recessed layer are in contact with each other.

[0010] In a further embodiment, the outer side of the conical outer sleeve is provided with saw teeth, and the surface of the recessed layer is provided with grooves matching with the saw teeth.

[0011] In a further embodiment, the bottom surface of the inner bolt nut and the bottom of the inner cavity of the conical outer sleeve are both provided with serrated surfaces.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The present application adopts a needle gauge as the supporting structure of the bottom of its guide rail, and uses a conical bolt to press the side of the needle gauge. As the degree of tightening of the conical bolt increases, the needle gauge gradually presses against the guide rail, thereby raising the height of the guide rail on that side by means of the pressing method, and both sides can be adjusted, thereby ensuring the balance of the left and right sides of the guide rail. The leveling method occupies less space, and the leveling method can be more precise and subtle, and each set of needle gauges and bolts is arranged at multiple intervals, so that every part of the guide rail can be adjusted, and there are more adjustment points, which can not only meet the existing leveling methods but also meet the requirements of narrow spaces.

[0019] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" 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 limiting the present invention. In addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", and the like 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.

[0020] 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 by specific circumstances.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-4 In the embodiment of the present invention, a four-row ball linear guide increases the installation reference, including a slide rail 1 and a mounting seat 4, a needle gauge 2 is installed at the bottom of both sides of the slide rail 1, a conical bolt 3 is installed on the surface of the mounting seat 4, the side of the conical bolt 3 is fitted with the needle gauge 2, and a chamfer is provided on the bottom edges of both sides of the slide rail 1. The needle gauge 2 is fitted with the chamfer and the chamfer of the conical bolt 3 at the same time, and the chamfer can better cooperate with the circular cross section of the needle gauge 2.

[0023] When installing and leveling the guide rail, place the needle gauges 2 at intervals on the left and right sides of the guide rail. The needle gauges 2 are located at the chamfered edge of the bottom edge of the slide rail 1. Then align the conical bolts 3 with each bolt hole for installation. Each conical bolt 3 is fixed to each needle gauge 2. As the depth of the conical bolt 3 decreases, the needle gauge 2 can be pushed sideways. The slide rail 1 on the side is squeezed by the needle gauge 2, thereby increasing the height of the slide rail 1 on this side, thereby keeping the upper surface of the slide rail 1 in a flat state.

[0024] Example 2: Please refer to Figure 1-4 , which is different from Example 1 in that: a recessed layer 201 is provided on the surface of the needle gauge 2, the conical bolt 3 is in contact with the recessed layer 201 and is located at the lowest part of the recessed layer 201, and the conical bolt 3 is located at the bottom of the needle gauge 2 and also in the middle, so as to keep the restriction on the needle gauge 2 always in the middle position.

[0025] The conical bolt 3 includes a conical outer sleeve 301 and an inner bolt 302. The conical outer sleeve 301 is sleeved on the outer side of the inner bolt 302. The conical outer sleeve 301 and the recessed layer 201 are in contact with each other. The conical outer sleeve 301 and the outer side of the needle gauge 2 are in contact with each other. The more the conical structure moves downward, the more it can squeeze the needle gauge 2 to both sides.

[0026] The outer side of the conical outer sleeve 301 is provided with serrations, and the surface of the recessed layer 201 is provided with sawtooth grooves 202 that match with the sawtooth grooves 202. The sawtooth structure of the conical outer sleeve 301 can cooperate with the sawtooth grooves 202 to produce a gear meshing effect, thereby driving the needle gauge 2 to move laterally.

[0027] The bottom surface of the nut of the inner bolt 302 and the bottom of the inner cavity of the conical outer sleeve 301 are both provided with serrated surfaces, and the serrated surfaces of the bottom surface of the nut of the inner bolt 302 and the bottom of the inner cavity of the conical outer sleeve 301 are for improving the friction effect between the two.

[0028] Furthermore, in order to prevent the bolt from loosening, the conical bolt 3 can be divided into two parts: a conical outer sleeve 301 and an inner bolt 302. As the inner bolt 302 is continuously screwed downward, the conical outer sleeve 301 does not rotate, and the conical outer sleeve 301 and the inner side of the needle gauge 2 are raised to keep the conical outer sleeve 301 always at the lowest point in the center of the recessed layer 201. When the inner bolt 302 is loose, the inner bolt 302 rotates and drives the conical outer sleeve 301 through the serrated layer 303. The conical outer sleeve 301 can engage with the serrated groove 202 during rotation, and has a tendency to push the recessed layer 201 to rotate. In this way, the needle gauge 2 can be pushed to move laterally as a whole, and the conical outer sleeve 301 can move toward the highest point of the recessed layer 201 during the lateral movement, thereby reversely pressing the needle gauge 2 and the slide rail 1, so that the slide rail 1 has a tendency to react, further preventing the inner bolt 302 from loosening.

[0029] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
