Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rails, in particular to an integrated intelligent rolling linear guide rail pair. Background Art

[0002] Due to its excellent load-bearing capacity, motion accuracy, high service life, low friction coefficient, easy installation and maintenance and other performance characteristics, the rolling linear guide rail pair is widely used in the field of mechanical industry. The traditional rolling linear guide rail pair only has the functions of load-bearing and guiding, and does not have the positioning function. At the same time, the operating state data of the rolling linear guide rail pair cannot be detected.

[0003] With the diversified development of market demands, in some occasions, the guide rail is required to have integrated functions such as positioning and self-diagnosis. At present, some manufacturers in the market have integrated magnetic grating scales and inductive reading heads into the rolling linear guide rail pair, but they do not have the function of automatic diagnosis, and cannot collect and process data such as the stress state, temperature rise, motion state, and slider smoothness of the rolling linear guide rail pair and then intuitively display them. Only when individual components of the rolling linear guide rail pair are damaged can the specific situation be known. Summary of the Invention

[0004] The technical problem to be solved by the utility model is: to provide an integrated intelligent rolling linear guide rail pair in order to solve the problems existing in the prior art in the above background art.

The slider assembly includes a slider body and a composite sensor, and the composite sensor is embedded on the inner wall of the slider body and is arranged towards the combined magnetic grating scale;

[0008] A data processing system, which is arranged outside the guide rail, receives the data of the composite sensor, processes it and then feeds it back to the terminal device.

[0009] Further, the combined magnetic grating scale includes an incremental magnetic grating part and an absolute magnetic grating part. Both the incremental magnetic grating part and the absolute magnetic grating part are periodic magnetic gratings, and the absolute magnetic grating part is located on one side of the incremental magnetic grating part.

[0010] Further, the thickness of the combined magnetic grating scale is 0.1 mm,

[0011] As a technical means, the combined magnetic grating scale is fixed on the surface of the lower groove of the guide rail.

[0012] As another technical means, a long groove is formed in the lower groove of the guide rail, and the combined magnetic grating ruler is fixed in the long groove.

[0013] Furthermore, the composite sensor includes a housing and a measurement sensor, a vibration sensor, and a temperature sensor disposed inside the housing. The contacts of the measurement sensor, the vibration sensor, and the temperature sensor extend out of the housing, and the measurement sensor, the vibration sensor, and the temperature sensor transmit the detected data to the data processing system through wireless communication technology.

[0014] Even further, an installation groove for placing the housing is formed on an inner wall of one side of the slider body.

[0015] Further, reverse covers are provided on both sides of the slider body. Four raceways are provided on the reverse covers.

[0021] (3) Adding contact type mechanical sensors at the end of the guide rail can understand the force conditions of each channel through a reliable contact method;

[0022] (4) The composite sensor and the contact type mechanical sensors transmit the detected data to the data processing system through wireless communication technology, and then transmit it to the mobile terminal.

[0030] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0031] As Figures 1 to 3 shown, an integrated intelligent rolling linear guide pair includes a guide rail 1, a slider assembly 2 and a data processing system 3. A combined magnetic grating ruler 4 is provided on the lower groove 11 of the guide rail 1. The slider assembly 2 is arranged on the guide rail 1 and slides back and forth along it. It includes a slider body 21 and a composite sensor 5. The composite sensor 5 is embedded in the inner wall of the slider body 21 and is arranged towards the combined magnetic grating ruler 4. The data processing system 3 is arranged outside the guide rail 1. It receives the data of the composite sensor 5, processes it and feeds it back to the terminal device. The distance between the terminal device and the data processing system 3 < 50m (this distance depends on the wireless transmission protocol adopted by the data processing system 3 and the terminal device). The terminal device can be a smart phone or a tablet computer. The data is transmitted wirelessly, with high integration, smaller space and more convenient installation.

[0032] As shown in 1 and Figure 5 shown, both sides of the slider body 21 are provided with return covers 22. Four raceways 221 are provided on the return covers 22. Four contact type mechanical sensors 6 are connected to the end of the guide rail 1 corresponding to the setting angles of the four raceways 221. The contact type mechanical sensors 6 transmit the detected data to the data processing system 3 through wireless communication technology.

[0033] As Figure 2 shown, the combined magnetic scale 4 includes an incremental magnetic scale part 41 and an absolute magnetic scale part 42. Both the incremental magnetic scale part 41 and the absolute magnetic scale part 42 are periodic magnetic scales, and the absolute magnetic scale part 41 is located on one side of the incremental magnetic scale part 42. Specifically: The magnetic scale of the incremental magnetic scale part 41 is strip-shaped and evenly arranged. The absolute magnetic scale part 42 is a block magnetic scale and three strip-shaped magnetic scales with the same structure and evenly spaced are distributed at intervals. The width of the incremental magnetic scale part 41 is greater than that of the absolute magnetic scale part 42.

[0034] In this embodiment, the thickness of the combined magnetic scale 4 is 0.1 mm, and it is fixed on the surface of the lower groove 11 of the guide rail 1; alternatively, a long groove can be opened on the lower groove 11 of the guide rail 1, and the combined magnetic scale is fixed in the long groove.

[0035] As Figure 3 and Figure 4 shown, the composite sensor 5 includes a housing 51 and a measurement sensor 52, a vibration sensor 54, and a temperature sensor 53 arranged in the housing 51. The contacts of the measurement sensor 52, the vibration sensor 54, and the temperature sensor 53 extend out of the housing 51, and the measurement sensor 52, the vibration sensor 54, and the temperature sensor 53 transmit the detected data to the data processing system 3 through wireless communication technology. An installation groove 211 for placing the housing 51 is provided on one inner wall of the slider body 21.

[0036] In actual use, the composite sensor 5 is integrated on the slider body 21. After the slider assembly 2 is fitted with the guide rail 1, the optimal measurement distance between the composite sensor 5 and the combined magnetic scale 4 has been adjusted, which can ensure the best measurement effect.

[0037] During specific use: The data on the combined magnetic scale 4 is collected through the measurement sensor 52 on the composite sensor 5, and the absolute positioning of the slider assembly 2 on the guide rail 1 can be realized; the vibration and temperature data of the slider assembly 2 are collected through the vibration sensor 54 and the temperature sensor 53. The data processing system 3 analyzes the data through the vibration and temperature rise change data. The user can timely and effectively understand the operating performance of the slider assembly 2 online through the terminal device. If abnormalities of the slider assembly 2 are detected through vibration and temperature rise, the slider assembly 2 can be moved to the end of the guide rail 1, so that the contact type mechanical sensor 6 contacts the four raceways 221 on the return cover 22, and the force data transmitted by each contact type mechanical sensor 6 to the data processing system 3 is analyzed. The user can understand the cooperation situation between the guide rail 1 and the slider assembly 2 through the terminal device to plan maintenance matters, avoid unexpected shutdowns, and achieve the highest utilization efficiency of the equipment.

[0038] Inspired by the above ideal embodiments based on the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present utility model. The technical scope of the present utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
