Technical Field

[0001] This utility model belongs to the field of transmission component technology, and in particular relates to a linear guide slider structure. Background Technology

[0002] Linear guide slider structure is a device widely used in industrial production to achieve precise linear reciprocating motion. For example, a linear guide slider disclosed in patent application number CN202421779889.3 is used in computer pattern making machines. It includes a slider that is slidably mounted on a guide rail. Both ends of the slider are equipped with end caps. The slider and end caps are provided with ball circulation channels. Balls are provided in the ball circulation channels. The balls slide in cooperation with ball grooves provided on both sides of the guide rail. The end caps are provided with oil nozzles that communicate with the ball circulation channels. The slider is provided with a main oil passage that connects to the oil nozzles. The main oil passage extends along the direction of the guide rail. Both ends of the main oil passage are provided with branch oil passages that communicate with the ball circulation channels. Filter grooves are provided on the inner walls on both sides of the middle of the main oil passage.

[0003] During use, the existing linear guide slider structure is prone to bending or misalignment under the influence of external forces when installed over long distances. Furthermore, foreign objects can easily accumulate between the guide rail and the slider, affecting the working stability of the linear guide slider structure. Therefore, it is necessary to make improvements. Utility Model Content

[0040] In one embodiment of this utility model, the linear guide rail slider structure includes: a guide rail 1, on which a slider 2 is arranged;

[0041] It also includes: a base 3, which is composed of a base plate 30, a side plate 31 and an extension 32. There are multiple bases 3 and they can be fixedly connected to each other by a support connector 4; a protective cover plate 5, which is arranged on the top of the base 3 to prevent foreign objects from entering the base 3; and a support sliding block 6, which is movably mounted on the base 3 by a guide rail 1 and a slider 2. The support sliding block 6 can be driven by a drive unit 7 to move back and forth linearly along the length of the base 3. The support sliding block 6 includes an insertion cavity 60 for accommodating the protective cover plate 5 and a plug-in part 61 that cooperates with the extension 32.

[0042] The base plate 30 is provided with a placement part 33 for mounting the guide rail 1 and the drive unit 7.

One end of the lower panel 63 is fixedly connected to one insertion part 61, and the other end has a gap 65 communicating with the insertion cavity 60 between it and another insertion part 61. The gap 65 is used to accommodate the support connector 4.

[0047] The upper panel 62 can be fixedly connected to industrial equipment in a conventional manner. The insertion part 61 is formed on the inner side of the side panel in such a way that it forms a plurality of bent parts that surround the extension part 32 of the base 3, so that the extension part 32 can be inserted into the insertion part 61. The connecting part 64 is also groove-shaped so as to be fixedly connected to the drive unit 7.

The mover 72 is fixedly mounted on the connecting part 64 of the lower panel 63. The mover 72 of the linear motor moves on the stator 70 to drive the support sliding block 6 to move.

[0050] Preferably, conventional end caps can be installed on both sides of the base 3.

[0051] The protective cover 5 is roughly in the shape of an inverted channel steel. The size of the protective cover 5 roughly covers the open top of the base 3 in both the longitudinal and transverse directions. The downward-extending parts on both sides of the protective cover 5 can cooperate with the extension part 32 of the base 3 to form staggered blocking areas to block foreign objects. The bottom surface of the protective cover 5 can be connected and fixed to the support connector 4. The two ends of the protective cover 5 can be connected and fixed to the end caps.

[0052] The support connector 4 further includes: a first support connector 40, which is rod-shaped and used to fix the adjacent base 3; and a second support connector 41, which includes an insert plate 410 and a support plate 412 fixed above the insert plate 410 by a vertical support rod 411.

[0053] The base plate 30 has two semi-grooves 300 on each side of its end. The semi-grooves 300 on adjacent base plates 30 can be combined to form a complete groove that mates with the first support connector 40 and the insert plate 410, respectively. The first support connector 40 and the insert plate 410 can be fixedly connected to the complete groove with bolts. The support plate 412 is fixedly connected to the bottom surface of the protective cover plate 5.

[0054] The vertical support rod 411 includes a plate body connected to the insert plate 410 and a support rod portion extending vertically upward from the plate body. The support plate 412 is fixedly installed at the top of the support rod portion. The plate body and the insert plate can be fixedly connected by conventional bolts.

[0055] In this embodiment, multiple bases 3 are fixedly connected by support connectors 4 to achieve long-distance splicing. At the same time, in cooperation with the protective cover plate 5 and the support sliding block 6, the splicing stability of the linear guide slider structure during long-distance installation can be improved, the risk of deformation can be reduced, and the accuracy of linear motion can be ensured. Meanwhile, through the cooperation of the protective cover plate 5, the inner cavity 34, the extension part 32 and the insertion part 61, the phenomenon of foreign object intrusion can be effectively prevented, the phenomenon of foreign object accumulation between the guide rail 1 and the slider 2 can be reduced, and the working stability of the linear guide slider structure can be further improved.

[0056] In another embodiment, the guide rail 1 further includes: a sliding layer 8, which is a copper alloy layer and has colored reflective properties; and a guide groove 9, which is disposed on both sides of the guide rail 1, and the surface of the guide rail 1 groove has a different roughness than the sliding layer 8.

[0057] Preferably, the bottom of the guide rail 1 is a base layer, which can be hypoeutectoid steel or stainless steel. The sliding layer 8 is arranged above the base layer, and the surface arithmetic mean roughness of the guide groove 9 is less than 60% of the surface roughness of the sliding layer 8.

[0058] Preferred, the copper alloy of sliding layer 8 contains tin, nickel, iron and other components to enhance wear resistance and colored reflective properties.

[0059] In this embodiment, the sliding layer 8 will gradually wear down as the linear guide rail slider structure reciprocates. The surface of the upper sliding layer 8, which is composed of wires, will gradually disappear. Due to the difference in roughness between the inner surface of the guide groove 9 and the exposed surface of the sliding layer 8, the gloss of the reflected light is different, thus forming a clear outline. At the same time, the visual contrast is further amplified by the specific wavelength reflection (red / yellow) of the copper alloy, so that the user can quickly judge the wear state of the sliding layer 8 by using the difference in light reflection, and thus replace and maintain the slider 2 of the guide rail 1 in a timely manner.

[0060] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
