[0079] The utility model provides a container end frame assembly platform.

[0080] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings. Figure 1 , Figure 2 and Figure 3As shown, the container end frame assembly station 100 includes a frame chassis 20, a positioning platform 30, a ball screw 40 and a driving mechanism, wherein two frame chassis 20 are arranged relatively along a first direction D1, and each frame chassis 20 is provided with two positioning platforms 30 movable along the first direction D1. The two positioning platforms 30 arranged on the same frame chassis 20 are spaced apart along a second direction D2 perpendicular to the first direction D1. The ball screw 40 is arranged to the frame chassis 20 along the first direction D1, and the respective nuts 42 of each ball screw 40 are respectively connected to the positioning platform 30. Two driving mechanisms are respectively arranged to the two frame chassis 20, and the driving mechanisms are connected to the two ball screws 40 of the same frame chassis 20 so that the screws 41 of the two ball screws 40 rotate synchronously at the same speed.

[0081] The utility model drives the screws 41 of the two ball screws 40 arranged on the same frame chassis 20 to rotate synchronously at the same speed by setting a driving mechanism, thereby driving the two positioning platforms 30 arranged on the same frame chassis 20 to move synchronously, with high precision and good reliability. In addition, the diagonal size of the container end frame assembly platform 100 is guaranteed, and the assembly requirements of various special container end frames can be met.

[0082] More specifically, if Figure 1 and Figure 2 As shown, two frame chassis 20 are arranged relatively along the first direction D1, and each frame chassis 20 can be transported and installed independently, occupying less space and weight, convenient for lifting or other modes of transportation, and convenient for installing the container end frame assembly platform 100 in a narrow space. The frame chassis 20 can be reliably fixed to the ground by bolts, for example. Each frame chassis 20 includes a shell 20A and a crossbeam 20B arranged at intervals along the first direction, and the shells 20A of the two frame chassis 20 are arranged on the relatively outer sides, and the crossbeam 20B are arranged on the relatively inner sides. For example, a driving mechanism is arranged inside the shell 20A for easy installation and maintenance. The two positioning platforms 30 arranged on each frame chassis 20 are arranged at intervals along the second direction D2 perpendicular to the first direction D1 of the frame chassis 20, and the positioning platforms 30 located on different frame chassis 20 are arranged correspondingly along the first direction D1, that is, the four positioning platforms 30 can form a rectangle.

[0083] like Figure 2 and Figure 3As shown, the frame chassis 20 is provided with a linear guide 60, which is arranged between the housing 20A and the crossbeam 20B and extends along the first direction D1, and the positioning platform 30 is provided with a sliding member 61, which is movably connected to the linear guide 60, and the sliding member 61 can be configured as a slider, for example. Further, the linear guide 60 can be configured as, for example, a dovetail groove linear guide 60, and the sliding member 61 provided on the positioning platform 30 is correspondingly configured as a slider with a dovetail groove. At least one linear guide 60 can be provided corresponding to each positioning platform 30. Two ball screws 40 are provided corresponding to the two positioning platforms 30, and the screw 41 of the ball screw 40 is arranged between the housing 20A and the crossbeam 20B along the first direction D1, and the respective nut 42 of each ball screw 40 is respectively connected to the positioning platform 30, that is, the rotation of the screw 41 can drive the nut 42 and the positioning platform 30 to move in the first direction D1. A linear guide rail 60 may be provided on both sides of each ball screw 40 along the second direction D2, and the ball screw 40 is provided at the center of the two linear guide rails 60 along the second direction D2. Therefore, during the movement of the positioning platform 30, the linear guide rail 60 and the ball screw 40 are subjected to more uniform force, and the movement of the positioning platform 30 is more stable, which is conducive to improving the accuracy and service life of the container end frame assembly platform 100.

[0084] A protective cover 62 extending along the first direction D1 is provided above the linear guide 60 and the ball screw 40, and both ends of the protective cover 62 are fixedly connected to the frame chassis 20. A sliding sleeve 31 is provided at the bottom of the positioning platform 30, and the sliding sleeve 31 is movably sleeved on the outer periphery of the protective cover 62. A plurality of sliding sleeves 31 can be provided corresponding to the plurality of protective covers 62, and the plurality of sliding sleeves 31 are respectively connected to the nut 42 of the ball screw 40 and the sliding member 61. The sliding sleeve 31 and the sliding member 61 can be driven to move together along the first direction D1 by the nut 42. By providing the protective cover 62, the ball screw 40, the linear guide 60 and the sliding member 61 can be hidden therein, effectively reducing the entry of welding slag dust, thereby increasing their service life.

[0085] like Figure 4As shown, the frame chassis 20 also includes a rack locking mechanism 70, the rack locking mechanism 70 includes a rack 71 and a locking member 72, two racks 71 are arranged on both sides of the frame chassis 20 along the second direction D2, and the rack 71 extends along the first direction D1. The locking member 72 is detachably arranged on the positioning platform 30, for example, arranged on the sliding sleeve 31, and the locking member 72 is provided with a tooth shape engaged with the rack 71. When the positioning platform 30 moves to a suitable position, the locking member 72 can be installed on the positioning platform 30 by bolts, and the locking member 72 is engaged with the rack 71 fixed to the frame chassis 20 to fix the positioning platform 30 on the frame chassis 20. Compared with locking mechanisms such as electromagnetic locks that are prone to displacement when subjected to external force impact during assembly, the utility model selects to use a mechanical rack locking mechanism 70, and the locking effect is more solid and not prone to displacement.

[0086] Specifically, Figure 1 and Figure 5 As shown, the driving mechanism includes a motor 51, a driving wheel 52, a first driven wheel 53 and a second driven wheel 54. The motor 51 is arranged on the housing 22A of the frame chassis 20, for example, fixed to the housing 22A by bolts. The motor 51 is a servo motor with a self-locking function, so that it can cooperate with the rack locking mechanism 70 to achieve a better fixing effect. The driving wheel 52 is connected to the output shaft of the motor 51, and the driving wheel 52 is driven by the motor 51 to rotate clockwise or counterclockwise. The two first driven wheels 53 are rotatably arranged on the housing 22A of the frame chassis 20, and are arranged at intervals along the second direction D2. Each first driven wheel 53 and the driving wheel 52 are connected by a synchronous belt, and the two first driven wheels 53 can be driven to rotate synchronously by the driving wheel 52. The second driven wheel 54 is connected to the screw 41 of the ball screw 40, and each second driven wheel 54 is connected to a first driven wheel 53 through a synchronous belt, that is, the driving wheel 52 can drive the two driven wheels, that is, the screws 41 of the two ball screws 40 to rotate synchronously through the first driven wheel 53, thereby controlling the two positioning platforms 30 arranged on the same frame chassis 20 to synchronously move along the first direction D1 between the shell 20A and the crossbeam 20B, and the direction and speed of the screw 41 can be controlled by the motor 51.

[0087] The container end frame assembly station 100 may also include a numerical control system (not shown). The numerical control system may include, for example, a programmable logic controller and a touch screen, and the programmable logic controller and the motor 51 are electrically connected. The programmable logic controller can control the direction and speed of the motor 51, and then control the positioning platforms 30 located on different frame chassis 20 to move in opposite directions or opposite directions, quickly reach the position, and ensure the adjustment accuracy. The operator can input various parameters, such as the length and width dimensions of the container end frame, through the touch screen. The numerical control system may have a zero point function to prevent accumulated errors. The numerical control system also has a fine-tuning function. When the length process parameters of the container end frame change during the production process, for example, the change data can be input through the touch screen to achieve fine-tuning. The drive mechanisms of the two frame chassis 20 can be synchronously adjusted by the numerical control system to ensure the synchronization of the movement of the four positioning platforms 30, so as to meet the production requirements of the common end frame that needs to be centered and symmetrically positioned. Alternatively, the drive mechanism of each frame chassis 20 can be adjusted separately to meet the production requirements of the special end frame that needs to be non-centered during assembly.

[0088] The container end frame assembly platform 100 may also include a lifting chain conveyor (not shown). The lifting chain conveyor is, for example, disposed between two frame chassis 20. When the container end frame is assembled, the lifting chain conveyor can be controlled by the numerical control system to rise, so that the container end frame leaves the assembly positioning surface. When the positioning height is exceeded, the lifting chain conveyor can be further controlled to be transmitted forward, and the container end frame can be transported to the next workbench for the next step.

[0089] like Figure 1 As shown, the container end frame assembly platform 100 further includes a first clamping mechanism 21 and a second clamping mechanism 22, wherein the two first clamping mechanisms 21 are arranged between the two frame chassis 20 along the second direction D2. Two second clamping mechanisms 22 are arranged on each frame chassis 20, and the two second clamping mechanisms 22 are arranged on the frame chassis 20 along the second direction D2 at intervals, and are arranged in the first direction D1 corresponding to the two positioning platforms 30 respectively. The first clamping mechanism 21 and the second clamping mechanism 22 are used to fix the container end frame to be assembled.

[0090] Specifically, Figure 6 As shown, the first clamping mechanism 21 includes a first clamping platform 23 and a first adjustment base 24. The first clamping platform 23 is movably disposed on the first adjustment base 24 along the second direction D2. Similar to the frame chassis 20, the first adjustment base 24 is provided with a ball screw 40, a linear guide 60 and a protective cover 62 along the second direction D2. Figure 3, similar to the positioning platform 30, the lower surface of the first clamping platform 23 is provided with a sliding sleeve 31 and a sliding member 61, and the sliding sleeve 31 and the sliding member 61 can be driven by the nut 42 of the ball screw 40 to move on the protective cover 62 and the linear guide 60 along the second direction D2. The difference is that the ball screw 40 here is not driven by a driving mechanism, but can be manually operated by a handle 25 rotatably arranged on the first adjustment base 24, and the screw 41 of the ball screw 40 can be controlled to rotate by the handle 25, thereby controlling the first clamping platform 23 to move along the second direction D2. The second clamping mechanism 22 includes a second clamping platform 26 and a second bracket 27, and the second bracket 27 is sleeved on one side of the frame chassis 20, and the second bracket 27 is provided with multiple rows of threaded holes arranged along the second direction D2. A flange plate 28 is provided at the lower end of the second clamping platform 26, and the flange plate 28, i.e., the second clamping platform 26, can be fixed to different positions on the second bracket 27 along the second direction D2 by bolts. The pressure feet of each of the first pressing mechanism 21 and the second pressing mechanism 22 can be adjusted independently, and the number of the butted pressure feet can be flexibly selected according to the assembly requirements of the container end frame.

[0091] like Figure 2 As shown, the positioning platform 30 includes a positioning plate 32, which is detachably disposed on the upper surface of the positioning platform 30. The positioning plate 32 is fixed to the positioning platform 30 by bolts, for example. Figure 2 and Figure 7 As shown, the positioning plate 32 is provided with a first positioning hole and a first positioning mechanism 33, and the first positioning mechanism 33 is provided with a protrusion for cooperating with the first positioning hole, so as to be detachably connected to the first positioning hole. The first positioning mechanism 33 is used to abut against the end of the container end frame along the first direction D1, that is, to position the container end frame in the first direction D1. In the process of the nut 42 of the ball screw 40 driving the positioning platform 30 to move along the first direction D1, when the positioning platforms 30 located at two different frame chassis 20 are all moved to the outermost side, that is, the position farthest from the other frame chassis 20, the two first positioning mechanisms 33 located at the above two positioning platforms 30 have a maximum distance in the first direction D1, and the maximum distance is, for example, 3200mm. Similarly, when the positioning platforms 30 located at two different frame chassis 20 are all moved to the innermost side, that is, the position closest to the other frame chassis 20, the two first positioning mechanisms 33 located at the above two positioning platforms 30 have a minimum distance in the first direction D1, and the minimum distance is, for example, 1450mm. The positioning platforms 30 located on two different frame chassis 20 include both two positioning platforms 30 correspondingly arranged in the first direction D1 and two positioning platforms 30 located on a diagonal line.

[0092] like Figure 2 and Figure 7As shown, the positioning plate 32 is also provided with a second positioning hole and a second positioning mechanism 34, and the second positioning mechanism 34 is provided with a protrusion for cooperating with the second positioning hole, so as to be detachably connected to the second positioning hole. A plurality of second positioning holes are provided to the positioning plate 32, for example, along the second direction D2, and the second positioning mechanism 34 is provided to one of the plurality of second positioning holes, for abutting against the end of the container end frame along the second direction, that is, positioning the container end frame in the second direction D2. When the two second positioning mechanisms 34 located on the same frame chassis 20 are both provided at the outermost second positioning holes, the two second positioning mechanisms 34 have a maximum distance in the second direction D2, and the maximum distance is, for example, 2800mm. Similarly, when the two second positioning mechanisms 34 located on the same frame chassis 20 are both provided at the innermost second positioning holes, the two second positioning mechanisms 34 have a minimum distance in the second direction D2, and the maximum distance is, for example, 2200mm. It can be understood that the above situation is also applicable to the two second positioning mechanisms 34 respectively provided on the two positioning platforms 30 located on different frame chassis 20 and located on the diagonal line.

[0093] The utility model provides a detachable positioning plate 32, and can replace the positioning plate 32 with different positioning mechanisms according to production requirements, so as to facilitate the assembly of container end frames with special and multi-point positioning requirements, and the replacement is convenient, and the subsequent maintenance cost is also reduced. Of course, in other embodiments of the utility model, it is also possible to choose not to provide a detachable positioning plate 32, but directly provide the first positioning hole, the first positioning mechanism 33, the second positioning hole and the second positioning mechanism 34 on the upper surface of the positioning platform 30.

[0094] The distance between the two first positioning mechanisms 33 located on two different frame chassis 20 in the first direction D1 can correspond to the length of the container end frame, and the distance between the two second positioning mechanisms 34 located on the same frame chassis 20 in the second direction D2 can correspond to the width of the container end frame. That is, the container end frame assembly station 100 in the utility model can meet the assembly of container end frames with a length range of 1450 to 3200 mm and a width range of 2200 to 2800 mm, which basically covers all special container specifications, has a wide range of applications, and is highly practical. The container end frame assembly station 100 of the utility model can meet the assembly requirements of special containers of different specifications, has good applicability, and is designed as a multi-stage structure, which is convenient for transportation and installation, and is conducive to improving production efficiency and reducing maintenance costs.
