DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figure 1-4 A rotating device for manufacturing high-precision mechanical parts in this embodiment includes a bracket 1, on which a connecting shaft tube 2 is rotatably installed, one end of the connecting shaft tube 2 is connected to a clamping frame 3 for clamping mechanical parts, and the clamping frame 3 is provided with a clamp component for fixing the mechanical parts.

[0023] In this embodiment, the clamping assembly includes two clamping blocks 6, one clamping block 6 is directly rotatably connected to one end of the clamping frame 3, and a first threaded rod 5 is rotatably installed on the other clamping block 6. A threaded tube 4 is rotatably installed on the clamping frame 3, and the first threaded rod 5 is threadedly connected to the threaded tube 4. The distance between the two clamping blocks 6 can be adjusted by rotating the first threaded rod 5 to clamp mechanical parts.

[0024] It can be understood that the threaded tube 4 extends to the outside of the clamping frame 3 and a locking nut is installed on the outside of the threaded tube 4 to limit the rotation of the threaded tube 4 relative to the clamping frame 3 .

[0025] It should be noted that a primary motor 7 is fixedly installed on one end of the clamping frame 3, and the output end of the primary motor 7 is fixedly connected to a clamping block 6, so that after the two clamping blocks 6 clamp the mechanical parts, the primary motor 7 can pull the two clamping blocks 6 to rotate relative to the clamping frame 3, that is, pull the mechanical parts to rotate.

[0026] In another embodiment, the connecting shaft tube 2 in this embodiment is internally threaded with a second threaded rod 8, one end of which is rotatably connected to the clamping frame 3, and the distance of the clamping frame 3 relative to the bracket 1 can be adjusted by rotating the second threaded rod 8.

[0027] In this embodiment, hand wheels are welded to the ends of the first threaded rod 5 and the second threaded rod 8, so that the first threaded rod 5 and the second threaded rod 8 can be easily rotated and adjusted.

[0028] It should be noted that a first traction wheel 12 is fixedly installed on the outside of the connecting shaft tube 2, a secondary motor 13 is fixedly installed on the outside of the bracket 1, a second traction wheel 14 is fixedly installed on the output end of the secondary motor 13, and a first belt 15 is sleeved between the first traction wheel 12 and the second traction wheel 14. Through the synchronous rotation of the first traction wheel 12 and the second traction wheel 14, the secondary motor 13 can pull the connecting shaft tube 2 to rotate relative to the bracket 1, that is, pull the clamping frame 3 to rotate relative to the bracket 1.

[0029] A linkage component is provided on the outside of the clamping frame 3 in this embodiment, so that the clamping block 6 can be synchronously pulled by the secondary motor 13. The linkage component includes a bevel gear 17 rotatably installed on the outside of the clamping frame 3, and a first pulley 18 is fixedly installed on one end of the bevel gear 17. A second pulley 19 is fixedly installed on the outside of the threaded tube 4. A second belt 20 is sleeved between the first pulley 18 and the second pulley 19. Through the first pulley 18 and the second pulley 19, the rotation of the bevel gear 17 can be converted into a rotation acting on the clamping block 6.

[0030] In this embodiment, a bevel gear 16 is fixedly mounted on the surface of the bracket 1 , and the bevel gear 17 meshes with the bevel gear 16 and can rotate relative to the bracket 1 through the clamping frame 3 , thereby forcing the bevel gear 17 to mesh and rotate around the bevel gear 16 .

[0031] In order to adjust the separation of the bevel gear 17 and the bevel gear plate 16, a guide plate 9 is fixedly installed on one end of the connecting shaft tube 2 facing the clamping frame 3 in this embodiment, and a guide hole 10 is penetrated through the guide plate 9. A guide rod 11 is fixedly installed on the surface of the clamping frame 3, and the guide rod 11 corresponds to the guide hole 10 and is slidably connected to the guide hole 10.

[0032] The working principle of the above embodiment is:

[0033] When only axial rotation of the mechanical parts is required, the mechanical parts are placed between the two clamping blocks 6, the rotation of the threaded tube 4 is limited by the locking nut, and then the first threaded rod 5 is rotated so that the first threaded rod 5 rotates slightly relative to the threaded tube 4, thereby adjusting the distance between the two clamping blocks 6 to clamp the mechanical parts, and then the primary motor 7 is turned on so that the primary motor 7 can directly pull the clamping block 6 to rotate on the clamping frame 3;

[0034] When the mechanical parts need to be rotated axially and radially, after the mechanical parts are clamped, the second threaded rod 8 is rotated to adjust the position of the clamping frame 3 relative to the bracket 1, and the secondary motor 13 is controlled to start. The secondary motor 13 drives the connecting shaft tube 2 to rotate through the first traction wheel 12 and the second traction wheel 14. At this time, the clamping frame 3 and the connecting shaft tube 2 restricted by the guide rod 11 and the guide hole 10 rotate synchronously relative to the bracket 1 radially. During the rotation of the clamping frame 3 relative to the bracket 1, the bevel gear 17 is engaged around the bevel toothed disk 16 to rotate, and the first pulley 18 and the second pulley 19 pull the threaded tube 4 to rotate, so that the clamping block 6 connected to the threaded tube 4 can drive the mechanical parts to rotate axially relative to the clamping frame 3;

[0035] When only radial rotation of the mechanical parts is required, the second threaded rod 8 is rotated so that the second threaded rod 8 is threadably engaged with the connecting shaft tube 2, so that the clamping frame 3 at the end of the second threaded rod 8 is away from the bracket 1, that is, the bevel gear 17 is disengaged from the meshing state with the bevel gear disc 16.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0037] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
