[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] The following further elaborates on the present application with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the relevant utility model and not for limiting the utility model. Additionally, it should be noted that for the sake of description, only parts related to the relevant utility model are shown in the drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0033] The present utility model provides a screwing device with rotational adjustment displacement for assembling annular structural members. The annular structural members are provided with an even number of screw positions evenly spaced circumferentially. The illustration of the annular structural members is omitted in the drawings. The annular structural members are generally 12-screw-hole workpieces, 16-screw-hole workpieces, etc. according to the screw positions.

[0034] As shown Figures 1 to 5 in the figure, the screwing device includes a supporting carrier plate 1 with a window opening channel 10, a rotary ring base 2 provided on the supporting carrier plate 1 and having a rotary adjustment displacement, and an even number of screwing mechanisms 3 evenly distributed at circumferential intervals on the rotary ring base 2.

[0035] The number of screw stations is an integer multiple of the number of screwing mechanisms 3.

[0036] The screwing mechanism 3 includes a screw screwing end 30 passing through the window opening channel, and the screw screwing end has a lifting displacement and a rotary displacement.

[0037] Specific implementation process and principle description:

[0038] There are several screw stations on the annular structural member, and corresponding screw driving operations need to be carried out one by one. In the traditional method, generally, the alignment operation of a single screwing mechanism 3 is adopted, and the position is switched by rotating the annular structural member, which cannot meet the cooperation requirements of the automatic production line of the annular structural member.

[0039] In this case, the annular structural member can be aligned with the screwing device along the automatic conveying line or by means of supporting and feeding. At this time, the annular structural member does not need to rotate and other actions, and only the lifting of the supporting carrier plate 1 can meet the alignment and cooperation requirements. By rotating and switching the position of the rotary ring base 2, the switching displacement alignment operation of the screwing mechanism 3 thereon can be realized.

[0040] Taking a 12-screw-hole workpiece as an example, specifically, designs with 6 screwing mechanisms 3, 4 screwing mechanisms 3, and 2 screwing mechanisms 3 can be adopted. For a 12-screw-hole workpiece, the central angle corresponding between screw holes is 30 degrees.

[0041] When the 6-screwing-mechanism 3 scheme is adopted, after the first alignment and screwing, it is lifted and rotated by 30° for position switching, and all screw driving operations can be realized in two times successively.

[0042] When the 4-screwing-mechanism 3 scheme is adopted, after the first alignment and screwing, it is lifted and rotated by 30° for the second position switching operation. After completion, it is lifted and rotated forward by 30° or rotated backward by 60° for the second position switching operation, so as to realize all screw driving operations.

[0043] When 2 screwing mechanisms 3 are adopted, only five equidistant position switches are needed to meet all screw driving operations.

[0044] In a specific embodiment, an outer peripheral tooth belt 20 is provided on the outer periphery of the rotary ring base 2, a rotary driving source 4 is provided on the supporting carrier plate 1, and a driving gear disk 40 meshing with the outer peripheral tooth belt is provided on the rotary end of the rotary driving source 4.

[0045] Specifically, by rotating the driving source 4 to rotate the driving gear disk 40, the rotational displacement of the rotating ring base 2 is driven through the meshing transmission of the outer peripheral toothed belt 20, meeting the switching position adjustment requirements.

[0046] In a specific embodiment, the rotating driving source 4 includes a carrier 41 disposed on the supporting carrier plate and a rotating motor 42 disposed on the carrier. The rotating end of the rotating motor penetrates the carrier and is fitted with a driving gear disk.

[0047] Designed in this way, it meets the requirements of the rotating driving source 4 for mounting and transmission assembly, and the assembly cooperation is reliable and stable.

[0048] In a specific embodiment, a positioning arc plate 5 is provided at the top of the rotating ring base 2, and a number of positioning holes 50 are provided on the positioning arc plate 5; a positioning locking mechanism 6 for cooperating with the positioning holes is provided on the supporting carrier plate 1. The positioning locking mechanism 6 includes a positioning upright frame 61 disposed on the supporting carrier plate and a telescopic driving part 62 disposed on the positioning upright frame. A locking telescopic pin vertically facing the positioning hole is provided on the telescopic driving part.

[0049] Specifically, the positioning holes 50 on the positioning arc plate 5 are used for the limitation of the switching angle, and the number of positioning holes 50 can be set according to the number of required switching positions.

[0050] In practical applications, first, the locking telescopic pin is locked with a positioning hole 50. When switching positions, the telescopic driving part 62 drives the locking telescopic pin to unlock. After rotating and switching to the next positioning hole, it extends and locks again, thus ensuring the position accuracy of the switching.

[0051] In a specific embodiment, a pressing ring plate 7 with a lifting and floating displacement is provided at the bottom of the supporting carrier plate 1.

[0052] The pressing ring plate 7 meets the requirements of floating pressing and locking of the workpiece after screwing and abutting.

[0053] In a specific embodiment, the screwing mechanism 3 includes a screwing carrier 31 disposed on the rotating ring base and a lifting carrier 32 with a lifting and adjusting displacement disposed on the screwing carrier.

[0054] A screwing rotation power source 33 is provided on the lifting carrier 32. A screwing and changing type carrier 34 is provided at the free end of the screwing rotation power source 33. A screw screwing end 30 is detachably disposed on the screwing and changing type carrier.

[0055] Specifically, the use of the screwing and changing type carrier 34 can meet the requirements of efficient type change, and through the combination of rotation and lifting, it meets the requirements of screwing assembly stroke and screwing control.

[0056] In a specific embodiment, a floating carrier 35 located at the bottom of the lifting carrier is provided on the screwing carrier 31, and a telescopic floating element is provided between the floating carrier and the lifting carrier; a rotating shaft seat 350 with rotational displacement is provided on the floating carrier, and the screwing changeable carrier is arranged on the rotating shaft seat, and the screwing rotation power source is axially movable with the rotating shaft seat and is circumferentially synchronously transmitted and connected.

[0057] That is, the downward pressure and floating force of the floating carrier is used as the downward pressure power source for screwing. During the downward pressure process, the downward displacement generated by the rotation of the screwing end is matched with the movement, so that the screwing operation is more reliable and smooth.

[0058] From the above description, it can be found that the utility model has a screwing device with rotation adjustment displacement. By rotating the switching position, all screwing operations of several screw stations on the annular structure can be realized. A single station can realize all assembly, which is suitable for construction on the conveyor line of the annular structure. It meets the switching position precision control requirements, the switching position operation is efficient and smooth, and the positioning accuracy is guaranteed. It can realize floating crimping locking and screwing floating coordination, and the screwing assembly operation quality is reliable and stable.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
