Description

Technical Field

[0001] The invention relates to the technical field of guide rail sliders, and in particular to a linear guide rail slider. Background Art

[0002] The linear guide slider carries the load of the workpiece or equipment and effectively transfers this load to the guide rail, playing the role of supporting the bearing. This support ensures the smooth movement of the load on the guide rail and provides a guarantee for stable operation.

[0003] In the existing public documents, the patent publication number CN116221273A discloses a slider of a linear guide rail, which forms a second arc-shaped return channel through the side of the end cover facing the return plate; the reverser is buckled in the end cover, and the first arc-shaped return channel and the second arc-shaped return channel form a steel ball return channel; the reverser forms a cavity on the side facing away from the end cover, so that the overall wall thickness of the reverser tends to be uniform, and the wall thickness of each part of the reverser is more uniform, ensuring the accuracy of the reverser, ensuring the smooth return of the steel ball, and reducing the running jump and noise of the steel ball return. However, the slider still has the following defects during use:

[0004] When the slider is used for sliding on the linear guide, it needs to contact the linear guide surface through the steel balls to achieve rolling contact, so that the slider can slide stably on the linear guide. However, during the assembly process, the position of the steel balls is fixed, and they need to be matched with linear guides of the same size to be used together. For linear guides of different sizes and models, it is difficult for the slider to adjust the contact between the upper and lower steel balls according to the specified contact force according to the size requirements of the linear guide. This results in poor adjustable applicability of the slider, and for this purpose a linear guide slider is provided. Summary of the invention

[0020] 3. The present invention adopts a constant pressure adjustment rolling assembly. The electric cylinder pushes the contact pressure sensor downward. The contact pressure sensor carries the concave frame downward. The linkage groove plate drives multiple support shafts downward.

[0044] The method of using the linear guide slider of the present invention is as follows:

[0045] First, when the present invention performs the lower fixed pressure adjustment, the linear guide is placed between the two lower shaft frames 34, and then the linear guide is fixedly installed on the upper surface of the platform, and the driving motor 27 is started by the controller 14, and the driving motor 27 drives the linkage screw 25 to rotate inside the support frame 24, and the linkage screw 25 carries the two threaded sleeves 26 to move closer to each other under the action of the thread transmission force. The two threaded sleeves 26 respectively carry the two linkage frames 28 to move closer to each other, one linkage frame 28 moves right, and the other linkage frame 28 moves left.

[0046] The linkage frame 28 drives the sliding rod 29 to move rightward, and the sliding rod 29 can move upward along the inner wall of the linkage frame 28. The sliding rod 29 carries two limit support rings 30 to move rightward and slide upward. The sliding rod 29 carries the extrusion block 31 to move upward, and the extrusion block 31 drives the sliding sleeve block 36 to move upward. The sliding sleeve block 36 slides upward along the outer wall of the inclined slide rod 37, and the sliding sleeve block 36 slides upward along the inner wall of the sliding support frame 38. The extrusion block 31 carries the docking pressure sensor 32 to move upward, and the docking pressure sensor 32 drives the linkage block 33 to move upward. The linkage block 33 drives the lower shaft frame 34 to move upward, and the lower shaft frame 34 drives multiple lower steel balls 35 to move upward. Another lower shaft frame 34 can move upward, and multiple lower steel balls 35 inside the lower shaft frame 34 can contact and contact the lower corner inclined surface of the linear guide. Multiple lower steel balls 35 inside another lower shaft frame 34 can be pressed and contacted and contact the other lower corner inclined surface of the linear guide. When the extrusion generates force, it acts on the linkage block 33 through the lower shaft frame 34, and the linkage block 33 acts on the docking pressure sensor 32. When the pressure value sensed by the docking pressure sensor 32 is the same as the value set by the controller 14, the drive motor 27 is turned off by the controller 14.

[0047] Secondly, when the present invention performs upper fixed pressure adjustment, the housing 1 is supported by two support blocks 2 to increase the stability of the housing 1, and the support blocks 2 support the sliding frame 3, and the reduction motor 5 is started by the controller 14, and the reduction motor 5 drives the screw 4 to rotate inside the sliding frame 3, and the screw 4 carries the sleeve block 6 to move downward under the action of the thread transmission force, and the sleeve block 6 moves downward along the inner wall of the sliding frame 3, and the sleeve block 6 carries the sleeve strip 7 to move downward, and the sleeve strip 7 carries the pressure sensor 8 to move downward.

[0048] The sliding shaft 10 carries two limit rings 17 and slides rightward on the sliding frame 9, and the linkage bar 11 carries the upper shaft frame 12 to tilt downward, and the upper shaft frame 12 carries multiple upper steel balls 13 to tilt downward, and the multiple upper steel balls 13 inside the upper shaft frame 12 contact the upper corner inclined surface of the linear guide. The multiple upper steel balls 13 inside another upper shaft frame 12 contact the other upper corner inclined surface of the linear guide. The extrusion force of the multiple upper steel balls 13 is transmitted to the upper shaft frame 12, and then transmitted to the linkage bar 11 by the upper shaft frame 12, and then transmitted to the sliding shaft 10 by the linkage bar 11, and then transmitted to the sliding shaft 10 by the sliding shaft 10 to the sliding frame 9, and the sliding frame 9 supports the support block 15, and the support block 15 supports the guide column 16, and the sleeve strip 7 slides down along the outer wall of the guide column 16, and the pressure sensor 8 can realize pressure sensing of the sliding frame 9. When the pressure value sensed by the pressure sensor 8 is the contact pressure set by the controller 14, the reduction motor 5 is turned off by the controller 14.

[0049] Then, when the present invention performs constant pressure adjustment rolling, the controller 14 starts the electric cylinder 39, and the electric cylinder 39 pushes the contact pressure sensor 40 downward, and the contact pressure sensor 40 carries the concave frame 41 downward, and the concave frame 41 carries the linkage slot plate 42 downward. The linkage slot plate 42 drives multiple support shafts 43 to move downward, and the support shafts 43 carry rollers 44 to move downward. Multiple rollers 44 are pressed on the upper surface of the linear guide rail. When multiple rollers 44 move downward and contact the upper surface of the linear guide rail, contact extrusion force is generated, which is then transmitted to the support shaft 43 through the roller 44, and the support shaft 43 is transmitted to the linkage slot plate 42, and the linkage slot plate 42 is transmitted to the concave frame 41. The concave frame 41 is transmitted to the contact pressure sensor 40. When the contact pressure sensor 40 senses the pressure value, the electric cylinder 39 is closed through the controller 14.

[0050] Finally, when the present invention performs linear sliding, when the housing 1 moves, it will drive the electric cylinder 39 to move, and the electric cylinder 39 carries the contact pressure sensor 40 to move, and the contact pressure sensor 40 carries the concave frame 41 to move. The concave frame 41 carries the linkage groove plate 42 to move, and the linkage groove plate 42 carries multiple support shafts 43 to move, and the rollers 44 on the support shafts 43 can roll on the upper surface of the linear guide. The multiple lower steel balls 35 inside the lower shaft frame 34 can roll on the lower corner inclined surface of the linear guide, and the multiple lower steel balls 35 inside another lower shaft frame 34 can roll on the other lower corner inclined surface of the linear guide. At the same time, the multiple upper steel balls 13 inside the upper shaft frame 12 can roll on the upper corner inclined surface of the linear guide. The multiple upper steel balls 13 inside another upper shaft frame 12 can roll on the other upper corner inclined surface of the linear guide, which can realize specified pressure contact adjustment for linear guides of different sizes, and the adjustment applicability is wider.
