[0033] like Figure 1As shown, the present application provides a large die-casting assembly system, including: a base 1, a clamping device 2 is provided on one side of the base 1, and a positioning mechanism 300 for limiting the position of the die-casting and a clamping mechanism 500 for clamping the die-casting on the other side, the clamping device 2 includes an adjustment mechanism 21 and a clamping support mechanism 22, the adjustment mechanism 21 is installed on the base 1 and connected to the clamping support mechanism 22, and is used to drive the clamping support mechanism 22 to move in the Z direction, and the clamping support mechanism 22 includes an upper clamping arm 224 and a support arm 225. Specifically, the positioning mechanism 300 includes a first positioning mechanism 3 and a second positioning mechanism 4, and the clamping mechanism 500 includes a first clamping mechanism 5 and a second clamping mechanism 6. The large die-casting assembly system in this embodiment also includes a controller, which is used to select corresponding assembly data according to the die-casting to be assembled, and control the clamping support mechanism 22 to move to a specified position through the adjustment mechanism 21 according to the assembly data, and after the die-casting is placed on the support arm 225, the first positioning mechanism 3 and the second positioning mechanism 4, control the upper clamping arm 224, the first clamping mechanism 5 and the second clamping mechanism 6 to clamp the die-casting.

[0034] Different models of automobile bodies have different curved surfaces, and the die-cast parts spliced ​​together to form the car bodies also have different inclined curved surfaces. In the present application, the controller can adjust the clamping support mechanism 22 to the specified position of the assembly data of the die-cast part through the adjustment mechanism 21 according to the die-cast part to be assembled, so that the support plane composed of the clamping support arm 225, the first positioning mechanism 3 and the second positioning mechanism 4 matches the assembly plane of the die-cast part, and then the controller controls the clamping upper clamping arm 224, the first clamping mechanism 5 and the second clamping mechanism 6 to clamp the die-cast part on the assembly plane, ensuring that subsequent die-cast parts can be assembled stably. The clamping support arm 225 is located on one side of the base 1, and the first positioning mechanism 3 and the second positioning mechanism 4 are provided on the other side of the base 1. The adjustment mechanism 21 adjusts the clamping support mechanism 22 to different heights, so that the placement plane composed of the clamping support arm 225, the first positioning mechanism 3 and the second positioning mechanism 4 is tilted to adapt to the die-casting parts with different inclined surfaces; the controller can control the adjustment mechanism 21 to move the clamping mechanism 22 to the specified position of the assembly data according to the assembly data, without changing the assembly tooling, saving the time of changing the tooling, improving the assembly efficiency and reducing the production cost. Figures 1 to 3As shown, in a specific example provided by the present application, the adjustment mechanism 21 includes a linear motion component 201 and a fixing member 213, wherein the linear motion component 201 includes a mounting seat 212, a motor 211, a screw nut assembly and a slider 214, the mounting seat 212 is mounted on the base 1 through the fixing member 213, the motor 211 is mounted on the mounting seat 212, the output shaft of the motor 211 is driven to connect the screw nut assembly through a gear assembly, the screw nut assembly is arranged on the mounting seat 212 along the Z direction, the slider 214 is slidably mounted on the screw nut assembly, and the slider 214 is connected to the clamping support mechanism 22. Specifically, the gear assembly includes a driving gear and a driven gear that mesh with each other, and a gear box 217 that wraps the driving gear and the driven gear, the motor 211 is mounted on the gear box 217, the driving gear is sleeved on the output shaft of the motor 211 that extends into the gear box 217, and the driven gear is sleeved on the screw in the screw nut assembly that extends into the gear box 217. It should be noted that, in the present embodiment, the motor 211 is electrically connected to the controller, and the controller controls the motor 211 to rotate forward or reverse, thereby driving the screw in the screw-nut assembly to rotate forward or reverse through the gear set, so that the clamping support mechanism 22 connected thereto moves in the Z direction, which is used to clamp different types of die-castings.

[0035] In detail, the fixing member 213 and the screw nut assembly are respectively arranged on both sides of the mounting seat 212, and the mounting seat 212 is provided with a protective shell 215 of the screw nut assembly, and the slider 214 has connecting blocks extending from both sides of the width direction of the protective shell 215, and the two sides of the width direction of the protective shell 215 are respectively provided with sliding grooves 216 for guiding the connecting blocks to slide in the Z direction, and the clamping support mechanism 22 is arranged on the side of the mounting seat 212 opposite to the fixing member 213, and is fixedly connected to the two connecting blocks. In actual use, the slider 214 moves in the Z direction following the nut in the screw nut assembly, and the connecting block extends out of the protective shell 215 through the sliding groove 216, which is used to connect the clamping support mechanism 22, so that the clamping support mechanism 22 can move in the Z direction following the slider 214 through the connecting block.

[0036] like Figures 1 to 3As shown, in a specific example provided by the present application, the clamping support mechanism 22 also includes a clamping cylinder 221, a first clamping arm 222, a horizontal clamping arm 223 and a connecting member 226, the connecting member 226 is connected to the slider 214, the clamping cylinder 221 is mounted on the connecting member 226, the telescopic end of the clamping cylinder 221 is connected to one end of the first clamping arm 222, the other end of the first clamping arm 222 is fixedly connected to the horizontal clamping arm 223, the upper clamping arm 224 is mounted on one end of the horizontal clamping arm 223 away from the first clamping arm 222, the support arm 225 is mounted on the connecting member 226, and a clamping space 227 is provided between the support arm 225 and the upper clamping arm 224. In this embodiment, the first clamping arm 222 is rotatably connected to the telescopic end of the clamping cylinder 221, specifically, the first clamping arm 222 can rotate around a rotating shaft provided on the clamping cylinder 221 and perpendicular to the thickness direction of the clamping cylinder 221.

[0037] It can be understood that the die casting is placed in the clamping space 227 between the upper clamping arm 224 and the support arm 225 and is located on the support arm 225. The controller controls the motor 211 to rotate according to the assembly data of the die casting. The motor 211 drives the screw of the screw nut assembly to rotate through the gear assembly. The screw nut assembly drives the slider 214 to move in the Z direction. The connecting piece 226 connected to the slider 214 moves in the Z direction with the slider 214, driving the die casting above the connecting piece 226 to move in the Z direction until the support arm 225 moves the die casting to the position set by the assembly data. , the motor 211 stops rotating; the controller starts the clamping cylinder 221, and the telescopic end of the clamping cylinder 211 drives the first clamping arm 222 to rotate, and the horizontal clamping arm 223 and the upper clamping arm 224 connected to the first clamping arm 222 follow the first clamping arm 222 to rotate in the direction close to the support arm 225 until they reach the position set by the clamping cylinder 221 according to the assembly data, and the clamping cylinder 221 stops moving. At this time, the upper clamping arm 224 moves downward and cooperates with the support arm 225 to clamp the die-casting in the clamping space 227, so as to facilitate the die-casting to remain stable during the subsequent assembly process. It should be noted that in other embodiments, the first clamping arm 222 is fixedly connected to the moving end of the clamping cylinder 221, and the first clamping arm 222, the horizontal clamping arm 223 and the upper clamping arm 224 are synchronously moved in the Z direction by the moving end of the clamping cylinder 221, so that the upper clamping arm 224 and the support arm 225 press the die casting into the clamping space 227. Therefore, the present application does not limit the specific structure between the clamping cylinder 221 and the first clamping arm 222.

[0038] Further references Figures 1 to 3In a specific example provided by the present application, the connecting member 226 includes a vertical plate 2261, a horizontal plate 2262 and a support plate 2263. One end of the horizontal plate 2262 is connected to the vertical plate 2261, and the other end is connected to the support plate 2263. The lower half of the vertical plate 2261 is fixedly connected to the two connecting blocks of the slider 214, and the upper half is connected to the cylinder body of the clamping cylinder 221. The lower half of the vertical plate 2261 is connected to one end of the horizontal plate 2262, and the other end of the horizontal plate 2262 is connected to one end of the support plate 2263, and the other end of the support plate 2263 is connected to the support arm 225. This embodiment provides a specific structure of the connecting member 226, but the present application does not limit the specific structure of the connecting member 226. The specific structure that can meet the requirements of the clamping support mechanism being installed on the slider 214 and providing support for the support arm 225 is within the protection scope of the present application.

[0039] like Figure 1 , Figure 4 and Figure 5 As shown, in a specific example provided by the present application, the first positioning mechanism 3 includes a first positioning seat 31 and a first positioning pin 32. The bottom of the first positioning seat 31 is fixed to the base 1, and the first positioning pin 32 is installed on the top of the first positioning seat 31. The first clamping mechanism 5 includes a first clamping seat 51, a first driving cylinder 52, a first clamping arm 53 and a first clamping block 55; the first clamping seat 51 is installed on the base 1, the first driving cylinder 52 is installed on the first clamping seat 51, the moving end of the first driving cylinder 52 is connected to one end of the first clamping arm 53, and the other end of the first clamping arm 53 is connected to the first clamping block 55. The first driving cylinder 52 drives the first clamping block 55 through the first clamping arm 53 to clamp the die casting on the first positioning seat 31. It is worth mentioning that in this embodiment, the first driving cylinder 52 adopts a welding clamping cylinder, which will not be elaborated here. This embodiment provides the specific model of the welding clamping cylinder: AM1C JCK80X135AM1C, but this application does not limit the specific model of the welding clamping cylinder, which can be selected according to actual conditions and is not limited here.

[0040] In the present embodiment, the stroke direction of the first driving cylinder 52 is along the Y direction, and the mobile end of the first driving cylinder 52 is rotatably connected to one end of the first clamping arm 53. It is understandable that the die casting to be assembled has a first positioning point that matches the first locating pin 32. During use, the first positioning point of the die casting is placed on the first locating pin 32 along the Z direction. When the mobile end of the first driving cylinder 52 is extended or shortened, the first clamping arm 53 is driven to rotate and the first clamping block 55 connected to the first clamping arm 53 is rotated in the direction close to or away from the first locating pin 31, which is used to cooperate with the first mounting seat 31 to complete the loosening or clamping of the die casting. Since one end of the first clamping arm 53 is rotatably connected to the mobile end of the first driving cylinder 52, before the die casting is placed on the first locating pin 32, the first driving cylinder 52 can drive the first clamping arm 53 and the first clamping block 55 to rotate and offset the top of the first locating seat 31, which is convenient for the placement of the die casting. It should be noted that, in other embodiments, the first driving cylinder 52 is replaced by a driving source such as a hydraulic cylinder or an electric cylinder. In the present embodiment, the stroke direction of the first driving cylinder 52 is along the Y direction. It is understandable that in other embodiments, the stroke direction of the first driving cylinder 52 can also be along the Z direction. The mobile end of the first driving cylinder 52 is fixedly connected to the linear first clamping arm 53, and the other end of the first clamping arm 53 is fixedly connected to one end of the first clamping block 55, and the other end of the first clamping block 55 is located directly above the first positioning seat 31. By the movement of the mobile end of the first driving cylinder 52 in the Z direction, the first clamping arm 53 and the first clamping block 55 are moved in the Z direction, so that the first clamping block 55 and the first positioning seat 31 cooperate to compress or release the die casting. Thus, this application is not limited.

[0041] like Figure 1 , Figure 4 As shown, in a specific example provided by the present application, the first positioning seat 31 includes a first positioning mounting block 311, a first vertical positioning plate 312 and a first horizontal positioning plate 313. The first positioning mounting block 311 and the first horizontal positioning plate 313 are respectively located on both sides of the first vertical positioning plate 32. The first positioning mounting block 311 is fixed to the base 1 and is located at the bottom of the first vertical positioning plate 32. The first horizontal positioning plate 313 is located at the top of the first vertical positioning plate 32. The first positioning pin 32 is mounted on the first horizontal positioning plate 313 through the first positioning pin seat 321. In this embodiment, the first positioning mounting block 311 and the first vertical positioning plate 312 are an integrated structure.

[0042] like Figure 5As shown, specifically, the first clamping seat 51 includes a first clamping mounting block 511, a first vertical clamping plate 512 and a first horizontal clamping plate 513. The first clamping mounting block 511 and the first horizontal clamping plate 513 are respectively located on both sides of the first vertical clamping plate 512. The first clamping mounting block 511 is fixed to the base 1 and is located at the bottom of the first vertical clamping plate 512. The first horizontal clamping plate 513 is located at the top of the first vertical clamping plate 512. The first driving cylinder 52 is installed on the first horizontal clamping plate 513 and is located on the lower surface of the first horizontal clamping plate 513. A first base plate 54 is provided between the first clamping block 55 and the first clamping arm 53. A part of the first base plate 54 is located above the first clamping block 55. The first clamping block 55 has a first arc surface 551, which is used to cooperate with the first positioning pin 32 to prevent the first clamping block 55 from squeezing the first positioning pin 32 and causing damage during the process of clamping the die casting.

[0043] like Figure 1 , Figure 6 and Figure 7 As shown, in a specific example provided by the present application, the second positioning mechanism 4 includes at least one second positioning seat 41 and a second positioning pin 42 corresponding to each second positioning seat 41, the second positioning seat 41 is installed on the base 1, and the second positioning pin 42 is installed on the top of the corresponding second positioning seat 41. The second clamping mechanism 6 includes a second clamping seat 61, a second driving cylinder 62, a second clamping arm 63 and a second clamping block 65; the second clamping seat 61 is installed on the base 1, the second driving cylinder 62 is installed on the second clamping seat 61, the moving end of the second driving cylinder 62 is connected to one end of the second clamping arm 63, and the other end of the second clamping arm 63 is connected to a second substrate 64, the substrate 64 is connected to the second clamping block 65, and the second driving cylinder 62 drives the second clamping block 65 on the second substrate 64 through the second clamping arm 63 to clamp the die casting on the second positioning seat 61. In this embodiment, the stroke direction of the second driving cylinder 62 is along the Y direction, and the moving end of the second driving cylinder 62 is rotatably connected to one end of the second clamping arm 63. It is worth mentioning that in this embodiment, the second driving cylinder 62 adopts a welding clamping cylinder, which will not be elaborated here. This embodiment provides the specific model of the welding clamping cylinder: AM1C JCK80X135AM1C, but this application does not limit the specific model of the welding clamping cylinder, which can be selected according to actual conditions and is not limited here.

[0044] It is understandable that the die casting to be assembled has a second positioning point that matches the second positioning pin 42. During use, the second positioning point of the die casting is placed on the second positioning pin 42. When the mobile end of the second driving cylinder 62 is extended or shortened, the second clamping arm 63 is driven to rotate and the second substrate 64 connected to the second clamping arm 63 is rotated, so that the second clamping block 65 connected to the second substrate 64 is rotated in the direction close to or away from the second positioning pin 42, which is used to cooperate with the second mounting seat 41 to complete the loosening or clamping of the die casting. Because one end of the second clamping arm 63 is rotatably connected to the mobile end of the second driving cylinder 62, before the die casting is placed on the second positioning pin 42, the second driving cylinder 62 can drive the second clamping arm 63, the second substrate 64 and the second clamping block 65 to rotate and offset the top of the second positioning seat 41, which is convenient for the placement of the die casting. It should be noted that in other embodiments of the present application, the second driving cylinder 62 is replaced by a driving source such as a hydraulic cylinder or an electric cylinder. In the present embodiment, the stroke direction of the second driving cylinder 62 is along the Y direction. It is understandable that in other embodiments, the stroke direction of the second driving cylinder 62 may be along the Z direction. The moving end of the second driving cylinder 62 may be fixedly connected to the linear second clamping arm 63. The other end of the second clamping arm 63 is fixedly connected to the second substrate 64. The second substrate 64 is connected to one end of the second clamping block 65. The other end of the second clamping block 65 is located directly above the second positioning seat 41. By moving the moving end of the second driving cylinder 62 in the Z direction, the second clamping arm 63 and the second clamping block 65 are moved in the Z direction, so that the second clamping block 65 cooperates with the second positioning seat 41 to clamp or release the die casting in the Z direction. Therefore, this application is not limited thereto.

At this time, the die-casting support surface composed of the support arm 225, the first positioning pin 32 and the second positioning pin 42 is the same as the assembly plane of the die-casting in the assembly data, and finally the controller controls the clamping support mechanism 22, the first clamping mechanism 5, the second clamping mechanism 6 and the auxiliary clamping support mechanism 66 to clamp the die-casting on the die-casting support surface to ensure that the die-casting remains stable during the assembly process.
