Description

Technical Field

[0001] This utility model relates to the technical field of guiding equipment for lifting, pushing or raising mechanisms, and in particular to a compact adjustable guiding mechanism and its application as a guide column. Background Technology

[0002] Rising columns, as crucial mechanical components for achieving vertical lifting, are widely used in industrial humanoid robot lifting, logistics equipment, and automated production lines. The guide mechanism is a core component of the rising column, and its performance directly affects its stability and reliability. Currently, common guiding mechanisms for rising columns on the market mainly include slider guide rail solutions and some complex, high-end guide mechanism designs.

[0003] While existing slider-guided systems offer some guidance, they have significant shortcomings. Firstly, their force design is overly redundant. In lifting column scenarios, most of the force from above is borne by the electric cylinder, with the guiding mechanism primarily maintaining stability. The excessive force design of the slider-guided system leads to material waste and increased costs. Secondly, this solution occupies a large space, creating significant gaps between the inner and outer layers of the lifting column. This not only increases the overall collision volume of the lifting column's outer shell but also hinders a compact and aesthetically pleasing design, making it difficult to meet the space-constrained requirements of applications such as lifting industrial humanoid robots. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a compact and adjustable guiding mechanism and a guide column for its application.

[0005] This utility model proposes a compact and adjustable guide mechanism, including a mounting base. Unlike the prior art, the mounting base has a mounting groove, a bracket is provided in the mounting groove, and a roller is rotatably mounted on the bracket. The roller has a portion extending out of the mounting groove, and the distance by which the roller extends out of the mounting groove is adjustable.

[0006] As a further optimization of this utility model, the roller is rotatably mounted on the mounting shaft, and the mounting shaft is fixed on the bracket.

[0007] As a further optimization of this utility model, the bracket is provided with a sliding member, and the mounting base is provided with a sliding groove. The sliding member slides in the sliding groove to adjust the distance by which the roller extends out of the mounting groove.

[0008] As a further optimization of this utility model, it also includes a wedge block, which is located between the bottom surface of the mounting groove and the bracket. The mounting base is provided with an adjusting member, which abuts against the wedge block. The distance of the roller extending out of the mounting groove is adjusted by adjusting the distance of the adjusting member extending into the mounting groove.

[0009] As a further optimization of this utility model, the wedge block and the bracket are in surface contact, and the side of the wedge block opposite to the bracket is an inclined surface that gradually slopes away from the bracket from the side closer to the adjusting member. The wedge block is slidably installed in the mounting groove along the direction of displacement of the adjusting member into the mounting groove.

[0010] As a further optimization of this utility model, the side of the wedge block away from the bracket is in surface contact with the bottom surface of the mounting groove.

[0011] As a further optimization of this utility model, the sliding member is cylindrical, and the axis of the sliding member coincides with the axis of the roller.

[0012] As a further optimization of this utility model, the mounting base is provided with a mounting extension, and the mounting extension has mounting holes.

[0013] A guide post includes an inner post and an outer post sleeved outside the inner post, with a sliding gap between the outer post and the inner post, and a guide mechanism provided within the sliding gap, the guide mechanism being the aforementioned compact and adjustable guide mechanism.

[0014] As a further optimization of this utility model, the guiding mechanism includes a first guiding mechanism, the mounting base of which is installed on the inner wall of the outer column, and the rollers of the first guiding mechanism abut against the outer wall of the inner column; and / or:

[0015] The guiding mechanism includes a second guiding mechanism, the mounting base of which is installed on the outer wall of the inner column, and the rollers of the second guiding mechanism abut against the inner wall of the outer column.

[0016] The present invention proposes a compact and adjustable guide mechanism and its application guide column. The guide mechanism has a simple structure, low cost and compact structure. By adjusting the distance of the roller extending out of the mounting groove, the installation of the guide mechanism is facilitated while ensuring its guiding effect.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] like Figures 1-3 The compact and adjustable guide mechanism shown includes a mounting base 1 with a mounting groove 10 on one side. A bracket 2 is provided within the mounting groove 10 and can slide relative to the mounting groove 10. Preferably, to facilitate the sliding limit of the bracket 2 relative to the mounting groove 10, the side of the mounting groove 10 contacts the side of the bracket 2. A roller 3 is rotatably mounted on the bracket 2, and the roller 3 has a portion extending beyond the mounting groove 10. The distance the roller 3 extends beyond the mounting groove 10 is adjustable. The roller 3 can be mounted on the bracket 2 via a bearing. In this embodiment, preferably, the roller 3 is a bearing, mounted on a mounting shaft 4, and the mounting shaft 4 is fixed to the bracket 2. Specifically, a 617 / 3-ZZ bearing is used as the core roller 3. This bearing has good rotational flexibility and sufficient structural strength to meet the force requirements for maintaining stability of the guide mechanism in the lifting column.

[0026] When using this guide mechanism, the base is installed on a stationary component. The roller 3 abuts against the sliding member 5 that slides relative to the stationary component. During installation, the distance the roller 3 extends out of the mounting groove 10 is initially smaller than the distance the guide mechanism is installed on. After the mounting base 1 is installed on the stationary component, the distance the roller 3 extends out of the mounting groove 10 is adjusted to ensure that the roller 3 abuts against the sliding member 5 that slides relative to the stationary component, thereby achieving guidance. It should be noted that multiple sets of this guide mechanism can be set during the guiding process.

[0027] Specifically, the bracket 2 is provided with a slider 5, which is detachably mounted on the bracket 2. The mounting base 1 is provided with a sliding groove 11, and the slider 5 slides within the sliding groove 11 to adjust the distance by which the roller 3 extends out of the mounting groove 10. Figure 1 As shown, the sliding groove 11 can be an open groove, such as... Figure 2 As shown, the sliding groove 11 can be a waist-shaped groove. The sliding groove 11 is used to limit the profile of the roller 3 on the bracket 2. Specifically, in some embodiments, the tension stroke of the roller 3 is 0.26mm.

[0028] Preferably, the slider 5 is cylindrical, and can be mounted on the bracket 2 by means of threads or snap-fit, and the axis of the slider 5 coincides with the axis of the roller 3.

[0029] The distance from which the roller 3 extends out of the mounting groove 10 can be adjusted by the telescopic component. In order to reduce costs and ensure the compactness of the device, in this embodiment, a wedge 6 is specifically included. The wedge 6 is located between the bottom surface of the mounting groove 10 and the bracket 2. The position of the wedge in the mounting groove 10 can be adjusted. An adjusting component 7 is provided on the mounting base 1. The adjusting component 7 abuts against the wedge 6. The distance from which the adjusting component 7 extends out of the mounting groove 10 can be adjusted by adjusting the distance from which the roller 3 extends out of the mounting groove 10. The adjusting component 7 can be an adjusting bolt.

[0030] The wedge 6 is in surface contact with the bracket 2. The side of the wedge 6 opposite to the bracket 2 is an inclined surface that gradually slopes away from the bracket 2 from the side closer to the adjusting member 7. The wedge 6 is slidably installed in the mounting groove 10 along the direction of displacement of the adjusting member 7 into the mounting groove 10. When the adjusting member 7 is rotated to move into the mounting groove 10, the wedge 6 also moves accordingly, thereby causing the bracket 2 to move away from the bottom surface of the mounting groove 10 and increasing the displacement of the roller 3 extending out of the mounting groove 10.

[0031] Preferably, the side of the wedge 6 away from the bracket 2 is in surface contact with the bottom surface of the mounting groove 10, thereby increasing the clamping effect of the wedge 6 on the bracket 2.

[0032] To facilitate the installation of the mounting base 1, preferably, the mounting base 1 is provided with a mounting extension 12, and the mounting extension 12 has a mounting hole 120. The mounting base 1 is installed on a component by installing screws or other fasteners in the mounting hole 120.

[0033] like Figure 4 The guide column shown includes an inner column 9 and an outer column 8 sleeved outside the inner column 9. A sliding gap is formed between the outer column 8 and the inner column 9. A guide mechanism is provided in the sliding gap. The guide mechanism is a compact and adjustable guide mechanism. Multiple sets of guide mechanisms can be provided. In this embodiment, four sets of guide mechanisms are provided, and two non-adjacent sets of guide mechanisms are arranged opposite each other. The four sets of guide mechanisms are distributed at the four corners of the outer column 8.

[0034] like Figure 5 As shown, the guiding mechanism includes a first guiding mechanism 13, the mounting base 1 of the first guiding mechanism 13 is mounted on the inner wall of the outer column 8, and the roller 3 of the first guiding mechanism 13 abuts against the outer wall of the inner column 9; and

[0035] The guiding mechanism includes a second guiding mechanism 14. The mounting base 1 of the second guiding mechanism 14 is installed on the outer wall of the inner column 9. The roller 3 of the second guiding mechanism 14 abuts against the inner wall of the outer column. When the inner column 9 extends the distance from the outer column 8 to the maximum, the mounting base 1 of the second guiding mechanism 14 and the mounting base 1 of the first guiding mechanism 13 abut together, thereby realizing the function of limiting the inner column 9.
