[0035] Example

[0036] SeeFigures 1-4 As shown in the figure, a large shell overturning mechanism is mainly composed of a driving platform 1, a driving assembly 2, a transmission assembly 3 and a clamping assembly 4.

[0037] The driving platform 1 is the basic support part of the whole mechanism, which is composed of a driving carrier plate 11 and a back plate 12. The back plate 12 is firmly fixed on the driving carrier plate 11 to provide a stable mounting base for other assemblies.

[0038] The driving assembly 2 is placed on the driving carrier plate 11 and is the key to realize the overturning power. It includes a driving motor 21 and a speed reducer 22, which are drivingly connected. A long shaft 23 penetrates through the speed reducer and is connected thereto. When the driving motor 21 starts, the power is adjusted through the speed reducer 22, thereby driving the long shaft 23 to realize forward rotation or reverse rotation. The long shaft 23 is provided with axially distributed guide flat keys 24 at both ends, which provide accurate guidance and limiting for the subsequent movement of the transmission assembly 3.

[0039] The transmission assembly 3 is connected with the long shaft 23 through the guide flat keys 24. On the side away from the guide flat keys 24, the transmission assembly 3 is pivotally connected with the clamping assembly 4. It is worth noting that the transmission carrier plate 31 of the transmission assembly 3 is equipped with an adjusting cylinder 32, and the piston end of the adjusting cylinder 32 is fixed on the driving platform 1 through a connecting piece. Through the extension and retraction movement of the adjusting cylinder 32, the transmission assembly 3 can move back and forth on the guide flat keys 24. The main function of the above-mentioned adjusting cylinder 32 is to provide space for the subsequent clamping assembly 4 to clamp the product when clamping the product.

[0040] The clamping assembly 4 is designed with a fixed clamping end and a movable clamping end. The movable clamping end can move up and down under the drive of the clamping cylinder 41. Under the joint action of the fixed clamping end and the movable clamping end, the product can be stably clamped, and compared with the traditional large-volume clamping device, the clamping assembly can effectively save space while ensuring the clamping effect, which is conducive to the layout optimization on the production line.

[0041] Specifically, the back plate 12 is axially distributed with two straight linear guides 13, and the two straight linear guides 13 are in parallel. The transmission assembly 3 at both ends of the long shaft 23 has a close matching relationship with the straight linear guides 13. Specifically, the transmission carrier plate in the transmission assembly 3 is slidingly arranged on the straight linear guides 13. Such arrangement makes the transmission assembly 3 more stable when moving on the guide flat keys 24, ensuring the straightness and accuracy of its movement track.

[0042] The transmission assembly 3 in the embodiment is a power transmission component in the large shell overturning mechanism, which is mainly composed of a transmission carrier plate 31, a sliding shaft sleeve 33, a first synchronous wheel 34, a fixed shaft sleeve 35, a second synchronous wheel 36, a synchronous belt 37, an adjusting cylinder 32 and the like.

[0043] The transmission load plate 31 serves as the main structure of the transmission assembly 3 and plays a key role in bearing other components. A sliding shaft sleeve 33 is arranged at one end of the transmission load plate 31, and the sliding shaft sleeve 33 is in sliding connection with the guide flat key 24. Specifically, the sliding shaft sleeve 33 is provided with a clamping groove for embedding the guide flat key 24, and the sliding shaft sleeve 33 is moved by the guide flat key 24 through the clamping groove. This sliding arrangement allows the transmission assembly 3 to move smoothly on the guide flat key 24, thereby adjusting the axial position. Meanwhile, a first synchronous wheel 34 is arranged on the sliding shaft sleeve 33, and the sliding shaft sleeve 33 drives the first synchronous wheel 34 to rotate synchronously according to the rotation of the long shaft 23. This design ensures the stability and efficiency of power transmission.

[0044] The other end of the transmission load plate 31 is a fixed shaft sleeve 35, and a transmission sleeve is pivotally connected inside the fixed shaft sleeve 35. One end of the transmission sleeve is fixedly connected with the clamping assembly 4, which allows the power to be effectively transmitted from the transmission assembly 3 to the clamping assembly 4, thereby realizing the clamping action on the large shell product. The other end of the transmission sleeve is provided with a second synchronous wheel 36, and a synchronous belt 37 is arranged between the first synchronous wheel 34 and the second synchronous wheel 36. The presence of the synchronous belt 37 ensures reliable power transmission between the two synchronous wheels, making the entire transmission process more stable and accurate.

[0045] Preferably, a tensioning wheel mounting seat 38 is arranged on the transmission load plate 31, and a tensioning wheel in contact with the synchronous belt 37 is pivotally arranged on the tensioning wheel mounting seat 38. The presence of the tensioning wheel can effectively adjust the tension of the synchronous belt 37. During the operation of the equipment, the synchronous belt 37 may be loose due to long-term use or other factors, and the tensioning wheel can compensate for this looseness in time, ensuring that the synchronous belt 37 is always in a suitable tension state, thereby ensuring more stable and reliable power transmission between the first synchronous wheel 34 and the second synchronous wheel 36.

[0046] A protective cover is arranged outside the transmission load plate 31, which covers the transmission load plate 31, the sliding shaft sleeve 33, the first synchronous wheel 34, the fixed shaft sleeve 35, the second synchronous wheel 36, and the synchronous belt 37, improving the overall appearance and safety protection.

[0047] The clamping assemblies located on both sides of the long shaft 23 have the same structure, and for the sake of convenience, they are introduced uniformly.

[0048] The clamping assembly 4 bears the key product clamping function in the entire large shell turnover mechanism. It mainly includes a "mouth" type structure of the clamping frame 42, which provides stable support for the installation and movement of other components.

[0049] One side of the clamping frame 42 is fixedly connected with a transmission sleeve, receives power from the transmission assembly 3 through the transmission sleeve, and realizes the overturning action of the clamping assembly 4. Meanwhile, a long shaft 23 is used for synchronous transmission, so that the clamping frames 42 on both sides are synchronously overturned, the stability of the product on the clamping assembly 4 in the overturning process is guaranteed, and the product is prevented from being deformed in the overturning process. The opposite side of the clamping frame 42 is provided with a fixed clamping end and a movable clamping end.

[0050] The fixed clamping end is a fixed clamping plate 48, and the fixed clamping plate 48 is fixed on the clamping frame 42 and is provided with a first clamping block on the upper end face.

[0051] The movable clamping end comprises a pair of vertical sliding rails 43 arranged on the clamping frame 42, and the vertical sliding rails 43 are connected with a movable base plate 44 through sliding blocks, so that the movable base plate 44 can smoothly slide up and down along the vertical direction. The movable clamping plate 45 is arranged on the movable base plate 44, and the lower end face of the movable clamping plate 45 is provided with a second clamping block. The movable clamping plate 45 cooperates with the fixed clamping plate 48 to realize clamping of the product.

[0052] Meanwhile, a sliding plate 46 is arranged in the clamping frame 42, and the clamping frame 42 is provided with a avoiding groove for the cam follower. The sliding plate 46 is provided with an inclined cam groove 461, the clamping cylinder 41 is fixed on the clamping frame 42, the piston end of the clamping cylinder 41 is fixedly connected with a fixed block 47, the cam follower is slidably arranged in the cam groove 461, one end of the cam follower is pivotally connected with the fixed block 47, and the other end of the cam follower is pivotally connected with the movable base plate 44. When the clamping cylinder 41 drives the fixed block 47 to move back and forth, the cam follower moves back and forth in the cam groove 461, and pushes the sliding plate 46 to move linearly. The linear motion of the clamping cylinder 41 is converted into the vertical motion of the movable base plate 44 along the vertical sliding rail 43 through the inclined cam groove 461, and finally the effective clamping of the product with different thicknesses is completed in cooperation with the fixed clamping end.

[0053] Preferably, the clamping frame 42 is provided with a buffer 49 for limiting the movement of the fixed block 47. The buffer 49 can accurately limit the movement range of the fixed block 47. If necessary, a hard stopper can be arranged below the buffer 49 to prevent the fixed block 47 from overstroke due to excessive driving of the clamping cylinder 41 or other abnormal conditions, so as to guarantee the accuracy and safety of the clamping action.

[0054] The driving platform 1 in the utility model can move vertically. Specifically, the driving platform 1 is provided with a rack 5 outside, and the rack 5 provides a stable support frame for the whole movement structure. Vertical distribution electric cylinders 6 are arranged on the rack 5, the driving shafts of the electric cylinders 6 are connected with the driving platform 1, and the electric cylinders 6 have enough power to drive the driving platform 1 to move vertically.

[0055] In addition, the rack 5 is provided with a vertical side plate 51, which enhances the stability of the rack. A set of vertical guide rails 52 are arranged on the vertical side plate 51, and the vertical guide rails 52 are symmetrically distributed and located on both sides of the electric cylinder 6. The symmetric distribution design makes the driving platform 1 more uniform in force during up and down movement. The driving platform 1 is slidably connected with the vertical guide rails 52 through a sliding block, which ensures the stability and accuracy of the driving platform 1 during vertical movement, effectively reduces shaking and deviation, and guarantees the reliable operation of the entire mechanism.

[0056] The large shell overturning mechanism is a component of an integral assembly production line, and its power supply unit, control unit and gas supply unit are all provided by the integral machine, so that the large shell overturning mechanism meets the production requirements of the production line and closely cooperates with other production links, thereby improving the efficiency and stability of the entire production line.

Through careful design and optimization of the structure, the product of the large shell is more stable and reliable during overturning, can meet the overturning requirements of large shell products of different types, and improve the application range of the product.

[0058] In summary, the driving assembly drives the long shaft to rotate, which is the power source of the entire operation process. In particular, an adjustable and movable transmission assembly is arranged on both sides of the long shaft to effectively make room for the clamping product.
