And one or more of the components in the diagram may be necessary or non-essential, and the relative position relationship between the components in the above diagram can be adjusted according to actual needs.

[0029] In order to provide lubrication maintenance convenience and reliability, such as Figures 1 to 9 As shown, the utility model provides an NC flexible positioner, which includes: an x-axis mechanism 1, a y-axis mechanism 2, a z-axis mechanism 3, a first centralized conversion component 4, and a second centralized conversion component 5. The x-axis mechanism 1 is connected to the y-axis mechanism 2 via the first centralized conversion component 4 to form a horizontal linkage in the longitudinal and transverse directions. The y-axis mechanism 2 is connected to the z-axis mechanism 3 via the second centralized conversion component 5 to form a vertical and transverse linkage, thereby forming an x, y, and z three-axis linkage positioning platform.

[0030] Specifically, if Figures 3 to 5 As shown, in this example, the first centralized conversion component 4 includes: a first support member 41, a first clustering member 42, and a first oil pipe 43. The first clustering member 42 is connected to the linkage end of the x-axis mechanism 1. An oil pipeline is provided in the first clustering member 42. An oil nozzle 9 is provided on the first support member 41. The first support member 41 is connected to the first clustering member 42 to support the y-axis mechanism 2 and connect the oil pipeline with the oil nozzle 9. The first oil pipe 43 connects the oil pipeline and the lubrication point of the x-axis mechanism 1.

[0031] The x-axis mechanism 1 comprises: an x-axis base 11, an x-axis linear module 12, an x-axis screw mechanism 13, and an x-axis adapter plate 14. The x-axis linear module 12 and the x-axis screw mechanism 13 are arranged on the x-axis base 11, wherein the x-axis screw mechanism 13 comprises: a driving motor and a screw member, wherein the screw member is linked to the driving motor pulley, the x-axis linear module 12 is transmission-connected to the screw nut 131 of the x-axis screw mechanism 13 via the x-axis adapter plate 14, wherein the first clustering member 42 is connected to the slider 121 of the x-axis linear module 12, and a lubrication point is arranged in the slider 121 of the x-axis linear module 12, and the lubrication point is in the shape of a pipeline, that is, a pipeline is arranged in the slider 121, and its outlet faces the track of the x-axis linear module 12, and its inlet faces the outer wall of the slider 121 to dock with the first oil pipeline 43.

[0032] In addition, in a preferred embodiment, a lubrication point is also provided in the screw nut 131 of the x-axis screw mechanism 13. The lubrication point is in the shape of a pipe, with its outlet facing the screw of the x-axis screw mechanism 13 and its inlet facing the outer wall of the screw nut 131 and connected to the first oil pipeline 43.

[0033] Through this arrangement, all first oil delivery pipes 43 can be centrally managed through the first clustering member 42, and uniformly connected to the oil delivery nozzles 9 on the first support member 41, so as to provide separate lubricating oil input channels for different lubrication points, so as to control the injection amount and oil type respectively, thereby providing more detailed lubrication guarantee. At the same time, due to the structural design, the oil delivery nozzles 9 on the first support member 41 are exposed and arranged in the outward direction, thus providing a higher convenience for inputting oil.

[0034] In addition, it is worth mentioning that there is a drop between the first support member 41 and the first cluster member 42. By supporting the y-axis mechanism 2 through the first support member 41, a spacing space can be defined between the first cluster member 42 and the y-axis mechanism 2, and the space can be used to accommodate the first oil pipeline 43, thereby avoiding interference between the first oil pipeline 43 and the x-axis adapter plate 14 or the bottom surface of the y-axis mechanism 2. On the other hand, since the first support member 41 and the first cluster member 42 are structurally moved with the slider 121 of the x-axis linear module 12, the length of the first oil pipeline 43 is fixed, and there is no need to worry about interference problems during the transmission process of the x-axis mechanism 1, and reliability is guaranteed to a certain extent.

[0035] Further, such as Figure 6 to Figure 7As shown, the second centralized conversion component 5 includes: a second support member 51, a second cluster member 52, and a second oil pipeline 53. The second cluster member 52 is connected to the linkage end of the y-axis mechanism 2. An oil pipeline is provided in the second cluster member 52. An oil nozzle 9 is provided on the second support member 51. The second support member 51 is connected to the second cluster member 52 to carry the z-axis mechanism 3 and connect the oil pipeline with the oil nozzle 9. The second oil pipeline 53 is connected to the oil pipeline and the lubrication point of the y-axis mechanism 2.

[0036] The y-axis mechanism 2 includes: a y-axis base 21, a y-axis linear module 22, a y-axis screw mechanism 23, and a y-axis adapter plate 24. The y-axis linear module 22 and the y-axis screw mechanism 23 are arranged on the y-axis base 21, wherein the y-axis screw mechanism 23 includes: a driving motor, a screw member, and the screw member is linked to the driving motor pulley. The y-axis linear module 22 is transmission-connected to the screw nut 231 of the y-axis screw mechanism 23 via the y-axis adapter plate 24, wherein the second clustering member 52 is connected to the slider 221 of the y-axis linear module 22, and a lubrication point is arranged in the slider 221 of the y-axis linear module 22. The lubrication point is in the shape of a pipeline, with its outlet facing the track of the y-axis linear module 22 and its inlet facing the outer wall of the slider to dock with the second oil pipeline 53.

[0037] In addition, in a preferred embodiment, a lubrication point is provided in the screw nut 231 of the y-axis screw mechanism 23. The lubrication point is in the shape of a pipe, with its outlet facing the screw of the y-axis screw mechanism 23 and its inlet facing the outer wall of the screw nut 231 and connected to the second oil pipeline 53.

[0038] Through this arrangement, all the second oil delivery pipes 53 can be centrally managed through the second clustering member 52, and uniformly connected to the oil delivery nozzles 9 on the second support member 51, so as to provide separate lubricating oil input channels for different lubrication points, so as to control the injection amount and oil type respectively, thereby providing more detailed lubrication guarantee. At the same time, due to the structural design, the oil delivery nozzles 9 on the second support member 51 are openly installed and arranged in the outward direction, thus providing a higher convenience for inputting oil.

[0039] In addition, it is worth mentioning that there is a drop between the second support member 51 and the second cluster member 52. By supporting the z-axis mechanism 3 through the first support member 41, a spacing space can be defined between the second cluster member 52 and the z-axis mechanism 3, and the space can be used to accommodate the second oil pipeline 53, thereby avoiding interference between the second oil pipeline 53 and the y-axis adapter plate 24 or the bottom surface of the z-axis mechanism 3. On the other hand, since the second support member 51 and the second cluster member 52 are structurally moved with the slider 221 of the y-axis linear module 22, the length of the second oil pipeline 53 is fixed, and there is no need to worry about interference during the transmission of the y-axis mechanism 2, and reliability is guaranteed to a certain extent.

[0040] Further, such as Figures 8 to 9 As shown, the z-axis mechanism 3 includes: a z-axis support seat 31, a z-axis base 32, a z-axis linear module 33, a z-axis screw mechanism 34, a cluster adapter plate 35, and a third oil pipeline 36. The z-axis linear module 33 and the z-axis screw mechanism 34 are arranged on the z-axis base 32, wherein the z-axis screw mechanism 34 includes: a drive motor, a screw member, and the screw member is linked to the drive motor pulley. The z-axis base 32 is connected to the second support member 5 via the z-axis support seat 31. 1, the z-axis linear module 33 is connected to the screw nut 341 of the z-axis screw mechanism 34 through the cluster adapter plate 35, the cluster adapter plate 35 is provided with an oil delivery nozzle 9 on the side, and an oil pipeline connected with the oil delivery nozzle 9 is provided inside, wherein a pipeline-shaped lubrication point is provided inside the slider 331 of the z-axis linear module 33, the outlet of which faces the track of the z-axis linear module 33, and the inlet faces the outer wall of the slider and is connected to the oil pipeline through the third oil delivery pipe 36.

[0041] In addition, in a preferred embodiment, a pipeline-shaped lubrication point is provided in the screw nut 341 of the z-axis screw mechanism 34 , the outlet of which faces the screw of the z-axis screw mechanism 34 , the inlet faces the outer wall of the screw nut 341 and is connected to the third oil pipeline 36 .

[0042] Through this arrangement, the cluster adapter plate 35 can not only be used to match with the processed parts, but also all the third oil pipes 36 can be centrally managed and uniformly connected to the oil pipeline on the cluster adapter plate 35, so as to connect each oil nozzle 9 and provide separate lubricating oil input channels for different lubrication points to control the injection amount and oil type respectively, thereby providing more detailed lubrication guarantee. At the same time, due to the structural design, each oil nozzle 9 on the cluster adapter plate 35 is openly installed and arranged in the outward direction, thus providing a higher convenience for inputting oil.

[0043] It can be seen that through the above examples, the utility model cleverly establishes lubricating oil input pipelines for each lubrication point of the x-axis mechanism 1, the y-axis mechanism 2, and the z-axis mechanism 3, and manages the pipeline bundles, and at the same time, the oil nozzle 9 is exposed to the outside, thereby not only providing an independent lubrication and maintenance channel for each lubrication point, ensuring that different lubrication points are filled with lubricating grease of different specifications in a predetermined amount as needed, avoiding the service life being affected by lack of lubrication, but also avoiding the waste of resources caused by excessive addition of grease. Moreover, due to the design concept of the centralized conversion component in this case, there is no need to disassemble the equipment as a whole for lubrication and maintenance, which greatly improves the convenience of maintenance.

[0044] On the other hand, considering that the NC flexible positioner generally works in an environment where welding slag splashes, Figure 1 to Figure 2 As shown, an accordion cover 8 is also provided on the z-axis base 32, which can be customized with flame retardant and fireproof materials. The z-axis base 32 is enclosed to protect the internal z-axis linear module 33 and z-axis screw mechanism 34, and the x-axis base 11 and the y-axis base 21 can also be enclosed with a cover plate to protect the internal mechanism and avoid the intrusion of welding slag, so as to improve the reliability of the equipment.

[0045] On the other hand, considering the dragging and pulling phenomenon of the line in the x, y, and z three-axis linkage structure, in order to reduce line damage, such as Figure 1 to Figure 2 As shown, a pipeline drag chain 7 can be installed outside the circuit. In addition, in order to prevent the pipeline drag chain 7 from interfering with the movement of the three-axis linkage mechanism, the x-axis mechanism 1, the y-axis mechanism 2, and the z-axis mechanism 3 are respectively provided with a harness bridge 6 extending outward to carry the pipeline drag chain 7 of the x-, y-, and z-axis mechanisms, thereby ensuring that the pipeline drag chain 7 can be dragged in the direction of the trend on the outside as the x-, y-, and z-axis mechanisms move, so as to avoid interference with the linkage structure, thereby avoiding random dragging and pulling of external pipelines, or damage caused by friction with surrounding mechanisms, effectively ensuring the service life of the external unit pipelines, and ensuring the stability and reliability of the x-, y-, and z-axis linkage structure.
