[0009] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0010] Please also read Figure 1 and Figure 2 , and combined Figure 1 In part II of the present application, a rotating device 100 is provided in one embodiment of the present application. The rotating device 100 includes a base 10, a rotating table 20, a first guide rail 30, a second guide rail 40, a retaining frame 50, and a plurality of rolling elements 60. The base 10 serves as a supporting part of the entire rotating device 100, and provides rigidity and stability for the rotating table 20 during the rotation process. The rotating table 20 can rotate relative to the base 10, the first guide rail 30 is connected to the base 10, and the second guide rail 40 is connected to the rotating table 20, so that the rolling elements 60 in the retaining frame 50 can slide along the first guide rail 30 and the second guide rail 40 while rotating.

[0011] Specifically, the rotating table 20 is rotatably disposed on the base 10 . The rotating table 20 is used to support and position a workpiece (not shown) and drive the workpiece to rotate to adjust a processing position of the workpiece.

[0012] It is understandable that in order to enhance the stability of the rotating table 20 and facilitate positioning of the rotating table 20 , a scale (not shown) may be provided on the outer edge of the rotating table 20 or a measuring component such as an encoder (not shown) may be installed.

[0013] The first guide rail 30 is connected to a side of the base 10 facing the rotating platform 20 , and the second guide rail 40 is connected to a side of the rotating platform 20 facing the base 10 .

[0014] The first guide rail 30 and the second guide rail 40 cooperate with each other to achieve the purpose of guiding the smooth rotation of the rotating platform 20. The surfaces of the first guide rail 30 and the second guide rail 40 are smooth and have a certain hardness, which can ensure that the movement of the rotating platform 20 in any direction can be effectively supported, and at the same time can reduce wear and increase the service life of the first guide rail 30 and the second guide rail 40.

[0015] Please also read Figure 2 and Figure 3 The retainer 50 is annular in structure and is disposed between the first guide rail 30 and the second guide rail 40. The retainer 50 includes at least two brackets 51 connected end to end and in an arc-shaped structure, and each bracket 51 is provided with a plurality of through holes 511 disposed at intervals. A plurality of rolling elements 60 are disposed in the through holes 511 in a one-to-one correspondence, and each rolling element 60 is slidably connected to the first guide rail 30 and the second guide rail 40.

[0016] The function of the retainer 50 is to fix the position of the rolling element 60, reduce the risk of collision or jamming of the rolling element 60 when rotating in the through hole 511, ensure that the rolling element 60 can be distributed between the first guide rail 30 and the second guide rail 40, and provide a balanced support force for the rotation process of the rotating table 20. At the same time, the retainer 50 is composed of a plurality of brackets 51 connected end to end, which is convenient for disassembly and assembly, and is convenient for subsequent replacement and maintenance of the retainer 50.

[0017] At the same time, when the rotating table 20 rotates relative to the base 10 , the rolling element 60 synchronously rotates in the through hole 511 and is slidably connected between the first guide rail 30 and the second guide rail 40 , thereby reducing the friction between the first guide rail 30 and the second guide rail 40 .

[0018] In this embodiment, the rolling element 60 is a roller. It is understandable that the rolling element 60 can also be a ball or other suitable shapes, which are not limited here.

[0019] During use, the first guide rail 30 and the second guide rail 40 are respectively installed at the corresponding positions of the base 10 and the rotating table 20, and the multiple brackets 51 in the retaining frame 50 are spliced ​​end to end and placed on the base 10, and a rolling member 60 is placed in each through hole 511 of the bracket 51, so that one end of the rolling member 60 can contact the first guide rail 30. After the rotating table 20 is installed on the base 10, the other end of the rolling member 60 can contact the second guide rail 40. At this time, the first guide rail 30, the second guide rail 40, the retaining frame 50 and the rolling member 60 form a complete rolling guide rail structure. When the rotating table 20 rotates, the rolling member 60 rolls in the first guide rail 30 and the second guide rail 40 after being subjected to the rotational force, which plays a role in supporting and reducing friction.

[0020] The rotating device 100 (see Figure 1 ), a rolling element 60 is placed in a through hole 511 on each bracket 51 to replace the traditional sliding friction method, and the friction between the rolling element 60 and the first guide rail 30 and the second guide rail 40 is reduced by rolling, thereby improving the rotation efficiency. At the same time, the retaining frame 50 is composed of multiple brackets 51 connected end to end, which is convenient for disassembly and assembly, and easy to maintain.

[0021] Please continue reading Figure 2 and Figure 3 In one embodiment, each bracket 51 has a protrusion 512 at one end and a groove 513 at the other end, and the protrusion 512 of the bracket 51 is configured to extend into the groove 513 of another bracket 51 adjacent to the bracket 51. The above arrangement enables each bracket 51 to be quickly and reliably connected through the cooperation between the protrusion 512 and the groove 513, and also ensures that the multiple brackets 51 will not loosen or disengage during the rotation process, thereby improving the overall rotation device 100 (see Figure 1 ) security.

[0022] It is understandable that by decomposing the retainer 50 into a plurality of independently produced arc-shaped brackets 51, it is not only convenient for transportation and storage, but also the number of brackets 51 can be flexibly increased or decreased as needed in practical applications to adapt to the rotating tables 20 of different diameters. When a bracket 51 is damaged, only the damaged part needs to be replaced without replacing the entire retainer 50, thereby reducing the difficulty of maintaining the retainer 50.

[0023] During the installation process, the plurality of brackets 51 may be assembled into an annular retaining frame 50 before being placed on the base 10 , or may be assembled into an annular retaining frame 50 after being placed on the base 10 , and there is no limitation here.

[0024] See also Figure 3 In one embodiment, the protrusion 512 is a dovetail block, and the groove 513 is a dovetail groove matching the dovetail block. The cooperation between the dovetail block and the dovetail groove enables the brackets 51 to fit tightly together, thereby enhancing the rigidity and stability of the overall structure.

[0025] Please also read Figure 4 and Figure 5 In other embodiments, the shape of the protrusion 512 can be any one of a circle, a polygon or an irregular shape. The shape of the groove 513 is also any one of a circle, a polygon or an irregular shape matching the shape of the protrusion 512.

[0026] Please also read Figure 2 and Figure 6 In one embodiment, the first guide rail 30 and the second guide rail 40 each include a plurality of guide rail portions 70 spliced ​​in the circumferential direction, and both ends of each guide rail portion 70 are provided with splicing surfaces 71, and one of the splicing surfaces 71 matches the splicing surface 71 of the adjacent guide rail portion 70. Through the above arrangement, by using the first guide rail 30 and the second guide rail 40 spliced ​​by a plurality of guide rail portions 70, the circumference of the first guide rail 30 and the second guide rail 40 can be flexibly adjusted to adapt to the base 10 and the rotating table 20 of different diameters, thereby improving the rotation device 100 (see Figure 1 When the first guide rail 30 or the second guide rail 40 needs to be installed or replaced, each guide rail portion 70 can be handled separately without disassembling the entire first guide rail 30 and the second guide rail 40, which is convenient for operators to conduct daily inspections and maintenance, thereby reducing maintenance costs.

[0027] At the same time, joint surfaces 71 are provided at both ends of the guide rail portion 70 to ensure that adjacent guide rail portions 70 can fit closely together, thereby improving the overall rigidity of the first guide rail 30 and the second guide rail 40, and reducing the resistance of the rolling element 60 during movement, thereby ensuring the smooth operation of the turntable 20.

[0028] In one embodiment, the first guide rail 30 and the second guide rail 40 may be an integrally formed structure.

[0029] See also Figure 6 In one embodiment, the splicing surface 71 is inclined. Through the above configuration, the inclined splicing surface 71 can better disperse the stress on the two adjacent guide rail parts 70, thereby reducing the concentrated load on the connection part. At the same time, it can also increase the contact area of ​​the two adjacent splicing surfaces 71, improve the tightness of the two adjacent guide rail parts 70 when splicing, and thus reduce the existence of gaps.

[0030] In other embodiments, the joint surface 71 may also be any one of a straight joint surface, a concave-convex joint surface, an arc joint surface, a serrated joint surface, or other irregularly shaped joint surfaces, which is not limited here.

[0031] Please refer again Figure 2 and Figure 6 In one embodiment, each guide rail portion 70 is an arc-shaped structure. Through the above arrangement, the first guide rail 30 and the second guide rail 40 formed by splicing a plurality of guide rail portions 70 can be better arranged along the circumferential direction of the base 10 and the rotating table 20 to form a complete annular track.

[0032] It is understandable that the curvature radius of the arc-shaped guide rail portion 70 in the first guide rail 30 should be consistent with the center of the base 10 to ensure that the first guide rail 30 formed by splicing all the guide rail portions 70 can perfectly surround the base 10, thereby providing uniform support force.

[0033] Likewise, the curvature radius of the arc-shaped rail portion 70 in the second rail 40 should be consistent with the center of the rotating table 20 to ensure that the second rail 40 formed by splicing all the rail portions 70 can perfectly surround the rotating table 20, thereby providing uniform supporting force.

[0034] In one embodiment, the material of the first guide rail 30 and the second guide rail 40 includes spring steel, which can maintain good elasticity and toughness and is not prone to permanent deformation during the rotation process.

[0035] In one embodiment, the material of the first guide rail 30 and the second guide rail 40 further includes any one of stainless steel and alloy, which is not limited here.

[0036] Please refer again Figure 1 and Figure 2In one embodiment, the rotating device 100 further includes a first locking screw 80 and a second locking screw 90, wherein the first locking screw 80 is used to fix the first guide rail 30 on the base 10, and the second locking screw 90 is used to fix the second guide rail 40 on the rotating table 20. Through the above arrangement, the first locking screw 80 is mainly used to fix the first guide rail 30 on the base 10 to ensure that the connection between the first guide rail 30 and the base 10 is firm and reliable. Through the design of the first locking screw 80, the position of the first guide rail 30 can be easily adjusted, and it can be fixed after the position is determined to prevent the first guide rail 30 from being displaced during the rotation process. At the same time, the second locking screw 90 is used to fix the second guide rail 40 on the rotating table 20, playing the same fixing role, ensuring that the connection between the second guide rail 40 and the rotating table 20 is firm, thereby ensuring that the rotating table 20 can run smoothly during the rotation process. In one embodiment, a plurality of the first locking screws 80 and a plurality of the second locking screws 90 are provided, so as to further improve the stability when the first guide rail 30 is fixed on the base 10 and the second guide rail 40 is fixed on the rotating table 20 .

[0037] See also Figure 2 In one embodiment, a sealing groove 21 is provided on the side of the rotating platform 20 facing the base 10, and a stopper 11 is provided on the side of the base 10 facing the rotating platform 20. The stopper 11 is slidably disposed in the sealing groove 21. By using the sealing groove 21 and the stopper 11 in cooperation, a dynamic sealing interface can be formed between the rotating platform 20 and the base 10 to prevent oil or impurities in the external environment from entering the base 10, thereby protecting the rotating device 100 (see Figure 1 )’s internal components are not contaminated.

[0038] See also Figure 1 In one embodiment, the rotating device 100 further includes a driving member (not shown) for driving the rotating platform 20 to rotate relative to the base 10. By providing the driving member, the rotating platform 20 can be automatically controlled, reducing the need for manual operation, thereby improving work efficiency.

[0039] In one embodiment, the driving member includes any one of an electric motor, a hydraulic motor, a pneumatic motor, and a servo motor.

[0040] Please also read Figure 1 , Figure 2 and Figure 7 In one embodiment, the assembly and operation process of the rotating device 100 includes the following steps: First, the first guide rail 30 is installed and fixed on the base 10 , and the second guide rail 40 is installed and fixed on the rotating table 20 .

[0041] Next, multiple brackets 51 are connected end to end to form an annular retaining frame 50 , and the retaining frame 50 is placed on the base 10 , and a rolling element 60 is placed in each through hole 511 of the bracket 51 so that one end of the rolling element 60 can contact the first guide rail 30 .

[0042] Then, the rotating table 20 is mounted on the base 10 so that the other end of the rolling element 60 can contact the second guide rail 40. At this time, the first guide rail 30, the second guide rail 40, the retaining frame 50 and the rolling element 60 form a complete rolling guide rail structure.

[0043] Finally, the driving member is controlled to drive the rotating platform 20 to rotate relative to the base 10 .

[0044] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application.
