Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rails, in particular to a grinding device for rolling linear guide rails. Background Art

[0002] Rolling linear guides enjoy a wide range of applications, primarily in industrial automation, manufacturing, medical equipment, and scientific research laboratories. As a crucial mechanical transmission component, rolling linear guides enjoy a wide range of applications, primarily due to their high precision, high efficiency, and long life. With the increasing demand for industrial automation, rolling linear guides are increasingly used in automated production lines, controlling the position of robots, workpiece fixtures, and other key components to improve production efficiency and quality.

[0003] In order to ensure the dimensions of the guide rail and the slider after they are matched, the height and side dimensions of the slider need to be ground after it is assembled on the guide rail. The existing grinding method is to push the slider onto the guide rail after it is assembled, and then grind its height and side dimensions. Because grinding wheel dust is generated during grinding and the grinding wheel dust will melt into the grinding fluid, some of the grinding fluid will enter the interior of the slider. The grinding fluid with grinding wheel dust will affect the life and operation of the slider and guide rail. The slider needs to be completely disassembled to completely remove the grinding wheel dust. The assembly of the slider is very cumbersome, and the secondary assembly of the slider wastes a lot of labor costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is: the utility model provides a grinding device for a rolling linear guide rail, which supports and positions the slider through the grinding device, eliminates the need to assemble the slider, eliminates the possibility of component damage in this process, improves the processing quality of the product, and improves the product processing efficiency.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a grinding device for a rolling linear guide rail, comprising: a support for placing a slider; a support plate connected to a lifting component on the support and driven up and down by the lifting component; the support has a lower supporting surface, and the support plate has an upper supporting surface. The support plate moves upward so that the upper supporting surface first contacts the upper raceway of the slider, and then the lower raceway of the slider contacts the lower supporting surface to fix the slider.

[0006] Furthermore, in order to use the upper raceway and the lower raceway as machining reference positioning surfaces, when the slider is fixed, a portion of the upper support surface completely fits the upper raceway, and a portion of the lower support surface completely fits the lower raceway.

[0007] Furthermore, in order to ensure that the upper support surface and the lower support surface can accurately position the corresponding raceways, the upper support surface is arranged parallel to the upper raceway, and the lower support surface is arranged parallel to the lower raceway.

[0008] Furthermore, in order to achieve stable support for the slider, the upper supporting surface and the lower supporting surface are both planes inclined relative to the horizontal direction.

[0009] Furthermore, the upper support surface is arranged axially symmetrically on the support plate, and the lower support surface is arranged axially symmetrically on the support.

[0010] Furthermore, in order to improve the positioning progress of the slider and ensure the precise grinding of the slider, the angle between the extension lines of the two upper supporting surfaces is 90°, and the angle between the extension lines of the two lower supporting surfaces is 90°.

[0011] Furthermore, the support includes a base and a support column. When the slider is in a non-elevated state, the bottom surface of the slider is arranged on the base, and the lower support surface is provided on the support column.

[0012] Furthermore, in order to prevent the slider from having an excessive stroke that affects processing efficiency and positioning accuracy, the clearance between the slider and the support platform after the slider is lifted is 6-10 mm.

[0013] Furthermore, in order to prevent the remaining parts of the pillar and the support plate from touching the slider, there is a gap between the left and right side surfaces of the pillar and the support plate and the slider.

[0014] Furthermore, the lifting component is a hydraulic cylinder, the cylinder barrel of the hydraulic cylinder is installed in the support, and the upper end of the piston rod of the hydraulic cylinder is connected to the support plate.

The reference does not change during processing, effectively ensuring the processing accuracy.

[0017] 2. The grinding device of the rolling linear guide rail of the utility model does not require the slider to be assembled with the slider return cover, upper and lower retaining frames, inserts, rollers and other parts, eliminating the possibility of parts damage in this process, reducing costs, reducing the possibility of damage to the guide rail raceway and slider raceway, and improving the processing quality of the product.

[0018] 3.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply 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 a limitation on the present invention. In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1 As shown, a grinding device for a rolling linear guide includes a support 1. A hydraulic cylinder 2 is mounted within the support 1. The cylinder barrel of the hydraulic cylinder 2 is mounted within the support 1, and the upper end of the piston rod of the hydraulic cylinder 2 is connected to a support plate 3. The hydraulic cylinder 2 is used to drive the upper support seat to move up and down.

[0028] The support 1 includes a support 11 and a support column 12. When installing the slider 4, the slider 4 is translated onto the support 11, and the support 11 first supports the slider 4.

[0029] The pillar 12 has a lower support surface 13, and the support plate 3 has an upper support surface 31. Both the upper support surface 31 and the lower support surface 13 are planes inclined relative to the horizontal. The upper support surface 31 is arranged axially symmetrically on the support plate 3, and the lower support surface 13 is arranged axially symmetrically on the support 1. The upper support surface 31 is arranged parallel to the upper raceway, and the lower support surface 13 is arranged parallel to the lower raceway. The upper support surface 31 and the lower support surface 13 correspond to the number of raceways of the slider 4. This ensures that the upper support surface 31 and the lower support surface 13 can perfectly fit the raceways, allowing the raceway of the slider 4 to serve as the processing reference positioning surface, ensuring that the reference does not change during processing.

[0030] The angle between the extension lines of the two upper support surfaces 31 and the extension lines of the two lower support surfaces 13 is 90°. The 90° angle can improve the positioning accuracy, and the positioning accuracy can reach μm level accuracy, which can achieve accurate grinding of the slider 4 size.

[0031] When processing the upper support surface 31 and the lower support surface 13, the support plate 3 needs to be lowered and fit with the pillar 12. The upper support surface 31 is processed once by a forming grinding wheel to ensure that the angle between the two is 90°. This can ensure the positional relationship of the 90° angle between the contact surfaces and the piston rod, thereby ensuring that when the piston cylinder rises, the upper contact surface and the raceway are completely fit to ensure its processing accuracy. The lower contact surface is processed in the same way. The four raceways of the slider 4 are also ground with a forming grinding wheel, with very high precision, and the 90° angle accuracy can reach 2"; the accuracy after positioning can reach μm level precision, which can achieve precise grinding of the slider 4 size.

[0032] There is a gap between the left and right sides of the pillars 12 and the support plate 3 and the slider 4. This can prevent the remaining parts of the pillars 12 and the support plate 3 from touching the slider 4 when the slider 4 is assembled and lifted, thereby avoiding damage to the slider 4.

[0033] like Figure 2 As shown, when the slider 4 needs to be ground, the slider 4 is first installed on the base 11. After the assembly is in place, the hydraulic cylinder 2 is started, the hydraulic cylinder 2 begins to lift, and the support plate 3 moves upward until the two upper support surfaces 31 fit the upper raceway of the slider 4. At this time, the piston rod continues to move upward, and the support plate 3 will push the slider 4 to move upward synchronously. The slider 4 moves upward until the lower raceway fits the lower support surface 13. Since the support 1 is fixed, a part of the upper support surface 31 completely fits the upper raceway, and a part of the lower support surface 13 completely fits the lower raceway. Therefore, the slider 4 cannot continue to move upward to achieve the fixation of the slider 4, as shown in FIG. Figure 3Under the action of the hydraulic cylinder 2, the upper support surface 31, and the lower support surface 13, the position of the slider 4 does not change, effectively ensuring the processing accuracy of the slider 4. After the slider 4 is processed, the hydraulic cylinder 2 retracts, and the slider returns to the support platform 11, and the slider can be removed.

[0034] The clearance between the slider 4 and the support 11 after the slider 4 is lifted is 6-10mm. The stroke of the slider 4 is limited to a small extent to avoid affecting the contact positioning accuracy of the slider 4 and the support 1 after the slider 4 is repositioned, and the lifting time of the slider 4 can be shortened to improve the processing efficiency.

[0035] To sum up, the grinding device of the rolling linear guide rail of the utility model supports and positions the slider through the grinding device, and there is no need to assemble the slider, thereby eliminating the possibility of component damage in this process, improving the processing quality of the product, and improving the product processing efficiency.

[0036] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of this utility model. The technical scope of this utility model is not limited to the content of the specification and must be determined according to the scope of the claims.
