Description

Technical Field

[0001] This utility model relates to the field of linear guide rails, and in particular to a high-speed linear track mechanism and module. Background Technology

[0002] Sliding guide rails are widely used in industrial equipment, CNC machine tools, automated production lines and other fields. Their core function is to support and guide moving parts to achieve high-precision, low-friction linear motion.

[0003] In existing technologies, guide rail lubrication systems mainly employ methods such as manual periodic oiling, gravity-fed oil supply from oil cups, or high-pressure spraying to lubricate the slider and guide rail. However, traditional lubrication devices typically use external oil circuits or independent lubrication units, resulting in complex structures and large space requirements. Furthermore, the uniform distribution of lubricating oil on the guide rail contact surface, especially under high-speed slider movement or prolonged operation, can easily lead to localized dry friction, causing accelerated wear on the guide rail and slider, and shortening their service life. Additionally, methods such as periodic oiling and gravity-fed oil supply make it difficult to adjust the oil supply in real time according to the slider's movement. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a high-speed linear track mechanism and module to improve the lubrication performance between the slider and the guide rail.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-speed linear track mechanism includes a guide rail and a slider that slides back and forth along the length of the guide rail. An immersion structure is provided in the slider so that lubricating oil is applied synchronously when the slider slides on the guide rail.

[0007] Furthermore, the slider includes a retainer located at an end position, and the wetting structure passes through the retainer to introduce lubricating oil between the retainer and the guide rail.

[0008] Furthermore, the immersion structure also includes an oil guide groove disposed on the retainer connecting the oil passage and the guide rail, the oil guide groove being located on the end face of the retainer facing the slider body.

[0009] Furthermore, the oil guide groove has a first guide groove and / or a second guide groove respectively leading to different sides of the guide rail, and the lubricating oil wets the guide rail through the first guide groove and / or the second guide groove under the action of gravity.

[0010] Furthermore, the end face protrudes towards the slider body relative to the oil guide groove.

[0011] Furthermore, an oil storage block is provided in the first guide groove and / or the second guide groove.

[0012] Furthermore, the first guide groove and / or the second guide groove are respectively connected to the first inner recess and / or the second inner recess of the guide rail.

[0013] Furthermore, the wetting structure introduces the lubricating oil between the cage and the guide rail through a cage oil passage that runs through the cage.

[0014] Furthermore, the cage oil passage is provided with internal threads.

[0015] The module includes the aforementioned high-speed linear guide mechanism.

[0016] The beneficial effects of this utility model are as follows:

[0017] The high-speed linear track mechanism and module provided by this utility model guides lubricating oil into the rolling elements by arranging an immersion structure in the slider cage. The oil guide groove's height difference oil storage structure has the advantages of restricting the oil flow path and maintaining uniform lubrication. Attached Figure Description

[0023] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. The above description is for the purpose of simplifying the description of this utility model and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0024] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include their plural forms. The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature but do not exclude the presence of one or more other features. The term “and / or” used in this specification includes any and all combinations of one or more of the relevant listed items.

[0025] In the specification, when an element is described as being "on," "fixed" to, "connected" to, or "joined" to another element, the element may be directly located on, fixed to, connected to, joined to, or in contact with the other element, or there may be an intermediate element present. In the specification, the description of a feature being arranged "adjacent" to another feature may refer to a feature having a portion that overlaps with the adjacent feature or a portion located above or below the adjacent feature.

[0026] It is understood that although the terms "first," "second," etc., may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Therefore, a first element may be referred to as a second element without departing from the teachings of this application.

[0027] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.

[0028] Figure 1 The overall structure of the high-speed linear track mechanism is shown, including a guide rail 100 and a slider 200 that is sleeved on the guide rail 100 and can slide back and forth along its length. The immersion structure 300 is integrated into the slider 200.

[0029] Reference Figures 2 to 4 The slider 200 consists of a slider body 220 and cages 210 disposed at both ends to maintain the position of the rolling elements within the slider 200 and control the height of the slider 200 relative to the guide rail 100. The cage 210 has a cage oil passage 320 that allows lubricating oil from the external oil supply pipe 310 to flow into the slider 200. Because rolling elements (not shown in the figure) that reduce friction between the slider 200 and the guide rail 100 are disposed in the common cavity 110, the lubricating oil flows into the rolling elements, maintaining the lubrication of the parts and extending their service life.

[0030] In a preferred embodiment, the cage oil passage 320 is provided with an internal thread to facilitate the connection and fixation of the oil supply pipe 310 to the cage oil passage 320 via a hard connector.

[0031] In a preferred embodiment, the wetting structure 300 is integrated into the retainers 210 at both ends of the slider 200.

[0032] The oil guide groove 212 of the immersion structure 300 is placed on the end face 211 of the retainer 210 facing the slider body 220. The end face 211 protrudes outward relative to the oil guide groove 212, which facilitates the flow of lubricating oil in the oil guide groove 212 and prevents it from overflowing due to the height difference. The rolling element of the slider 200 is in contact with the guide rail 100 at the first recess 120 and / or the second recess 130. The lower part of the oil guide groove 212 has a first guide groove 213 and a second guide groove 214 that lead to the first recess 120 and the second recess 130 of the guide rail 100, respectively. When the lubricating oil flows into the oil guide groove 212 from the oil passage 320 of the retainer through the oil passage opening 321, it flows downward under the action of gravity into the first guide groove 213 and the second guide groove 214, and finally into the first recess 120 and the second recess 130.

[0033] In a preferred embodiment, oil storage blocks (not shown in the figure) are further arranged in the first guide groove 213 and the second guide groove 214 to absorb and store lubricating oil and evenly release it onto the guide rail 100. The oil storage blocks are preferably porous elastic materials, such as sponges.
