[0001] This invention relates to the field of automotive assembly technology, and in particular to a large die-casting assembly system. Background Technology

[0002] Currently, lightweight design in automobiles has become an important development trend in the industry. To achieve lightweighting, unibody aluminum die-casting technology is typically used to enhance the strength of the lightweight body, and large die-cast parts are precision assembled.

[0003] However, different car models require different large die-cast parts, and the corresponding assembly tooling also varies. When switching between different car models, it is necessary to change the corresponding large and heavy tooling, which is not only time-consuming and labor-intensive, but may also lead to a decrease in stability and increase production costs. Summary of the Invention

[0005] This application provides a large die-casting assembly system, including: a base, a clamping device on one side of the base, and a positioning mechanism for defining the position of the die-casting and a clamping mechanism for clamping the die-casting on the other side. The clamping device includes an adjustment mechanism and a clamping support mechanism. The adjustment mechanism, mounted on the base, drives the clamping support mechanism to move in the Z direction. The clamping support mechanism includes an upper clamping arm and a support arm. The adjustment mechanism drives the clamping support mechanism to move to a designated position, so that the support arm and the positioning mechanism form a support platform for placing the die-casting.

[0006] In one embodiment, the large die-casting assembly system further includes a controller, which is used to select corresponding assembly data according to the die-casting to be assembled, control the clamping support mechanism to move to a designated position through the adjustment mechanism according to the assembly data, and control the upper clamping arm and the clamping mechanism to clamp the die-casting after the die-casting is placed on the support arm and the positioning mechanism.

[0007] In one embodiment, the adjustment mechanism includes a linear motion component and a fixing member. The linear motion component is mounted on the base via the fixing member. The linear motion component has a slider that moves along the Z-direction, and the slider is connected to a clamping support mechanism.

[0008] In one embodiment, the clamping support mechanism further includes a clamping cylinder, a first clamping arm, a horizontal clamping arm, and a connector. The connector is connected to the slider, the clamping cylinder is mounted on the connector, the telescopic end of the clamping cylinder is connected to one end of the first clamping arm, the other end of the first clamping arm is fixedly connected to the horizontal clamping arm, the upper clamping arm is mounted on the end of the horizontal clamping arm away from the first clamping arm, the support arm is mounted on the connector, and there is a clamping space between the support arm and the upper clamping arm.

[0009] In one embodiment, the positioning mechanism includes a first positioning mechanism and a second positioning mechanism;

[0010] The clamping mechanism includes a first clamping mechanism that cooperates with the first positioning mechanism and a second clamping mechanism that cooperates with the second positioning mechanism.

[0011] In one embodiment, the first positioning mechanism includes a first positioning seat and a first positioning pin, the bottom of the first positioning seat is fixed to the base, and the first positioning pin is installed on the top of the first positioning seat.

[0012] In one embodiment, the first pressing mechanism includes a first pressing seat, a first driving cylinder, a first pressing arm, and a first pressing block; the first pressing seat is mounted on a base, the first driving cylinder is mounted on the first pressing seat, the moving end of the first driving cylinder is connected to one end of the first pressing arm, and the other end of the first pressing arm is connected to the first pressing block. The first driving cylinder drives the first pressing block through the first pressing arm to press the die-casting part onto the first positioning seat.

[0013] In one embodiment, the second positioning mechanism includes at least one second positioning seat and a second positioning pin corresponding to each second positioning seat. The second positioning seat is mounted on a base, and the second positioning pin is mounted on the top of the corresponding second positioning seat.

[0014] In one embodiment, the second pressing mechanism includes a second pressing seat, a second driving cylinder, a second pressing arm, and a second pressing block;

[0015] The second clamping seat is mounted on the base, and the second driving cylinder is mounted on the second clamping seat. The moving end of the second driving cylinder is connected to one end of the second clamping arm, and the other end of the second clamping arm is connected to a second base plate. The second base plate is connected to the second clamping block. The second driving cylinder drives the second clamping block on the second base plate through the second clamping arm to press the die-casting part onto the second positioning seat.

[0016] In one embodiment, the second clamping mechanism further includes an auxiliary clamping support mechanism;

If they match, the controller controls the upper clamping arm and the pressing mechanism to clamp the die-casting.

[0019] In one embodiment, the identification mechanism further includes a first auxiliary sensor and a second auxiliary sensor. The first auxiliary sensor is mounted on the clamping support mechanism, and the second auxiliary sensor is mounted on the clamping mechanism. The first and second auxiliary sensors are used to transmit the signal that the die casting has reached the assembly position to the controller, so that the controller can control the upper clamping arm and the clamping mechanism to clamp the die casting.

[0020] The advantages of this application compared to the prior art are as follows:

[0021] In this application, the clamping support mechanism and the positioning mechanism are respectively located on both sides of the base, and the clamping support mechanism and the positioning mechanism form a placement plane for placing the die-cast parts. By adjusting the height of the clamping support mechanism in the Z-axis, the placement plane formed by the clamping support mechanism and the positioning mechanism is tilted to accommodate die-cast parts with different inclined curved surfaces. This application provides a large die-casting part assembly system that can adjust the clamping support mechanism to adapt to different die-cast parts through the adjustment mechanism, without the need to change assembly tooling, saving tooling change time, improving assembly efficiency, and reducing production costs.

[0032] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Therefore, they should not be construed as limitations on the present invention.

[0035] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0036] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0037] like Figure 1As shown, this application provides a large die-casting assembly system, including: a base 1, a clamping device 2 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. 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. The controller is used to select the corresponding assembly data according to the die-casting to be assembled, and to control the clamping support mechanism 22 to move to the designated position through the adjustment mechanism 21 according to the assembly data. After the die-casting is placed on the support arm 225, the first positioning mechanism 3 and the second positioning mechanism 4, the controller controls the upper clamping arm 224, the first clamping mechanism 5 and the second clamping mechanism 6 to clamp the die-casting.

[0038] Different car models have different curved surfaces, and the die-cast parts that assemble the car body also have different inclined curved surfaces. In this 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, 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. Then the controller controls the clamping upper clamping arm 224, the first pressing mechanism 5 and the second pressing mechanism 6 to press the die-cast part on the assembly plane, so as to ensure that the subsequent die-cast parts can be assembled stably. The clamping support arm 225 is located on one side of the base 1, and the other side of the base 1 is provided with a first positioning mechanism 3 and a second positioning mechanism 4. The adjustment mechanism 21 adjusts the clamping support mechanism 22 to different heights, causing the placement plane formed by the clamping support arm 225, the first positioning mechanism 3, and the second positioning mechanism 4 to tilt, so as to adapt to die-cast parts with different inclined curved surfaces. The controller can control the adjustment mechanism 21 to move the clamping support mechanism 22 to the specified position of the assembly data according to the assembly data, without the need to change the assembly tooling, saving the time of changing tooling, improving assembly efficiency, and reducing production costs. Figures 1 to 3As shown, in a specific example provided in this application, the adjustment mechanism 21 includes a linear motion component 201 and a fixing member 213. The linear motion component 201 includes a mounting base 212, a motor 211, a lead screw and nut assembly, and a slider 214. The mounting base 212 is mounted on the base 1 via the fixing member 213. The motor 211 is mounted on the mounting base 212. The output shaft of the motor 211 is driven and connected to the lead screw and nut assembly via a gear assembly. The lead screw and nut assembly is arranged along the Z-direction on the mounting base 212. The slider 214 is slidably mounted on the lead screw and nut assembly and is connected to a clamping support mechanism 22. Specifically, the gear assembly includes a meshing driving gear and a driven gear, and a gearbox 217 enclosing the driving gear and the driven gear. The motor 211 is mounted on the gearbox 217. The driving gear is sleeved on the output shaft of the motor 211, which extends into the gearbox 217, and the driven gear is sleeved on the lead screw in the lead screw and nut assembly, which extends into the gearbox 217. It should be noted that in this embodiment, the motor 211 is electrically connected to the controller. The controller controls the motor 211 to rotate forward or backward, and then drives the lead screw in the lead screw nut assembly to rotate forward or backward through the gear set, so that the clamping support mechanism 22 connected to it moves in the Z direction to clamp different types of die-cast parts.

[0039] In detail, the fixing member 213 and the lead screw and nut assembly are respectively disposed on both sides of the mounting base 212. The mounting base 212 is provided with a protective shell 215 for the lead screw and nut assembly. The slider 214 has connecting blocks that extend out of the two sides of the protective shell 215 in the width direction. The two sides of the protective shell 215 in the width direction are respectively provided with grooves 216 for guiding the connecting blocks to slide in the Z direction. The clamping support mechanism 22 is disposed on the side of the mounting base 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 with the nut in the lead screw and nut assembly. The connecting blocks extend out of the protective shell 215 through the grooves 216 to connect to the clamping support mechanism 22, so that the clamping support mechanism 22 can move in the Z direction with the slider 214 through the connecting blocks.

[0040] like Figures 1 to 3As shown in a specific example provided in this application, the clamping support mechanism 22 further 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, and 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 the 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 about a pivot axis disposed on the clamping cylinder 221 and perpendicular to the thickness direction of the clamping cylinder 221.

[0041] Understandably, the die-cast part 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-cast part. The motor 211 drives the lead screw of the lead screw and nut assembly to rotate through the gear assembly. The lead screw and nut assembly drives the slider 214 to move in the Z direction. The connecting piece 226 connected to the slider 214 moves with the slider 214 in the Z direction, driving the die-cast part above the connecting piece 226 to move in the Z direction until the support arm 225 moves the die-cast part 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. The horizontal clamping arm 223 and the upper clamping arm 224 connected to the first clamping arm 222 rotate with the first clamping arm 222 toward the support arm 225 until they reach the position set by the clamping cylinder 221 according to the assembly data. 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 part in the clamping space 227, so as to keep the die-casting part stable during subsequent assembly. It should be noted that, in other embodiments, the first clamping arm 222 and the moving end of the clamping cylinder 221 are fixedly connected. The movement of the moving end of the clamping cylinder 221 in the Z-direction causes the first clamping arm 222, the horizontal clamping arm 223, and the upper clamping arm 224 to move synchronously in the Z-direction, thereby enabling the upper clamping arm 224 and the support arm 225 to press the die-casting part tightly within the clamping space 227. Therefore, this application does not limit the specific structure between the clamping cylinder 221 and the first clamping arm 222.

[0042] Further reference Figures 1 to 3In one specific example provided in this application, the connector 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 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. The other end of the support plate 2263 is connected to the support arm 225. This embodiment provides a specific structure for the connector 226, but this application does not limit the specific structure of the connector 226. Any specific structure that can satisfy the requirement of mounting the clamping support mechanism on the slider 214 and providing support for the support arm 225 is within the protection scope of this application.

[0043] like Figure 1 , Figure 4 and Figure 5 As shown in the specific example provided in this 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 pressing mechanism 5 includes a first pressing seat 51, a first driving cylinder 52, a first pressing arm 53, and a first pressing block 55. The first pressing seat 51 is installed on the base 1, and the first driving cylinder 52 is installed on the first pressing seat 51. The moving end of the first driving cylinder 52 is connected to one end of the first pressing arm 53, and the other end of the first pressing arm 53 is connected to the first pressing block 55. The first driving cylinder 52 drives the first pressing block 55 through the first pressing arm 53 to press the die-cast part onto the first positioning seat 31. It is worth mentioning that the first drive cylinder 52 in this embodiment is a welding clamping cylinder, which will not be described in detail here. The specific model of the welding clamping cylinder provided in this embodiment is AM1C JCK80X135AM1C, but this application does not limit the specific model of the welding clamping cylinder. It can be selected according to the actual situation, and no restriction is made here.

[0044] In this embodiment, the stroke direction of the first driving cylinder 52 is along the Y direction, and the moving end of the first driving cylinder 52 is rotatably connected to one end of the first clamping arm 53. It can be understood that the die-cast part to be assembled has a first positioning point that cooperates with the first positioning pin 32. During use, the first positioning point of the die-cast part is placed on the first positioning pin 32 along the Z direction. When the moving end of the first driving cylinder 52 extends or retracts, it drives the first clamping arm 53 to rotate, causing the first clamping block 55 connected to the first clamping arm 53 to rotate towards or away from the first positioning pin 31, thereby cooperating with the first mounting seat 31 to release or clamp the die-cast part. Since one end of the first clamping arm 53 is rotatably connected to the moving end of the first driving cylinder 52, before the die-cast part is placed on the first positioning pin 32, the first driving cylinder 52 can drive the first clamping arm 53 and the first clamping block 55 to rotate and shift above the first positioning seat 31, facilitating the placement of the die-cast part. It should be noted that in other embodiments, the first drive cylinder 52 is replaced by a hydraulic cylinder or an electric cylinder, etc. In this embodiment, the stroke direction of the first drive cylinder 52 is along the Y direction. It can be understood that in other embodiments, the stroke direction of the first drive cylinder 52 can also be along the Z direction. The moving end of the first drive 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. The other end of the first clamping block 55 is located directly above the first positioning seat 31. By moving the moving end of the first drive cylinder 52 in the Z direction, the first clamping arm 53 and the first clamping block 55 move in the Z direction, thereby causing the first clamping block 55 to cooperate with the first positioning seat 31 to clamp or loosen the die-casting part. Therefore, this application does not impose any limitations.

[0045] like Figure 1 , Figure 4 As shown in the specific example provided in this application, the first positioning base 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 located at the bottom of the first vertical positioning plate 32, while 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 a first positioning pin seat 321. In this embodiment, the first positioning mounting block 311 and the first vertical positioning plate 312 are an integral structure.

[0046] 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 located at the bottom of the first vertical clamping plate 512, and the first horizontal clamping plate 513 is located at the top of the first vertical clamping plate 512. The first driving cylinder 52 is mounted on the first horizontal clamping plate 513 and 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 portion of the first base plate 54 is located above the first clamping block 55, and the first clamping block 55 has a first arc-shaped surface 551 for cooperating 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 clamping of the die-casting part.

[0047] like Figure 1 , Figure 6 and Figure 7 As shown, in a specific example provided in this 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 mounted on the base 1, and the second positioning pin 42 is mounted on the top of the corresponding second positioning seat 41. The second pressing mechanism 6 includes a second pressing seat 61, a second driving cylinder 62, a second pressing arm 63, and a second pressing block 65. The second pressing seat 61 is mounted on the base 1, and the second driving cylinder 62 is mounted on the second pressing seat 61. The moving end of the second driving cylinder 62 is connected to one end of the second pressing arm 63, and the other end of the second pressing arm 63 is connected to a second base plate 64. The base plate 64 is connected to the second pressing block 65. The second driving cylinder 62 drives the second pressing block 65 on the second base plate 64 through the second pressing arm 63 to press the die-cast part onto the second positioning seat 41. 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 pressing arm 63. It is worth mentioning that the second drive cylinder 62 in this embodiment is a welding clamping cylinder, which will not be described in detail here. The specific model of the welding clamping cylinder provided in this embodiment is AM1C JCK80X135AM1C, but this application does not limit the specific model of the welding clamping cylinder. It can be selected according to the actual situation, and no restriction is made here.

[0048] It is understood that the die-cast part to be assembled has a second positioning point that cooperates with the second positioning pin 42. During use, the second positioning point of the die-cast part is placed on the second positioning pin 42. When the moving end of the second drive cylinder 62 extends or retracts, it drives the second clamping arm 63 to rotate, causing the second base plate 64 connected to the second clamping arm 63 to rotate. This, in turn, causes the second clamping block 65 connected to the second base plate 64 to rotate towards or away from the second positioning pin 42, in order to cooperate with the second mounting seat 41 to release or clamp the die-cast part. Since one end of the second clamping arm 63 is rotatably connected to the moving end of the second drive cylinder 62, before the die-cast part is placed on the second positioning pin 42, the second drive cylinder 62 can drive the second clamping arm 63, the second base plate 64, and the second clamping block 65 to rotate and shift above the second positioning seat 41, facilitating the placement of the die-cast part. It should be noted that in other embodiments of this application, the second drive cylinder 62 is replaced by a hydraulic cylinder or an electric cylinder or other drive source. In this embodiment, the stroke direction of the second driving cylinder 62 is along the Y direction. It is understood that in other embodiments, the stroke direction of the second driving cylinder 62 can be along the Z direction. The moving end of the second driving cylinder 62 can be fixedly connected to a linear second clamping arm 63. The other end of the second clamping arm 63 is fixedly connected to a second base plate 64. The second base plate 64 is connected to one end of a second clamping block 65, and the other end of the second clamping block 65 is located directly above the second positioning seat 41. The movement of the moving end of the second driving cylinder 62 in the Z direction causes the second clamping arm 63 and the second clamping block 65 to move in the Z direction, thereby causing the second clamping block 65 to cooperate with the second positioning seat 41 to press or release the die-casting part in the Z direction. Therefore, this application does not impose any limitations.

[0049] like Figure 1 , Figure 6 and Figure 7 As shown, in a specific example provided in this application, the second positioning base 41 includes a second positioning mounting block 411, a second vertical positioning plate 412, and a second horizontal positioning plate 413. The second positioning mounting block 411 and the second horizontal positioning plate 413 are respectively located at the upper and lower ends of the second vertical positioning plate 412. The second positioning mounting block 411 is fixed to the base 1 and is located at the bottom of the second vertical positioning plate 412. The second horizontal positioning plate 413 is located at the top of the second vertical positioning plate 412. The second positioning pin 42 is installed on the second vertical positioning plate 413 through the second positioning pin seat 421.

[0050] like Figure 8As shown, specifically, the second clamping seat 61 includes a second clamping mounting block 611, a second vertical clamping plate 612, and a second horizontal clamping plate 613. The second clamping mounting block 611 and the second horizontal clamping plate 613 are respectively located on both sides of the second vertical clamping plate 612. The second clamping mounting block 611 is fixed to the base 1 and located at the bottom of the second vertical clamping plate 612, while the second horizontal clamping plate 613 is located at the top of the second vertical clamping plate 612. The second driving cylinder 62 is mounted on the second horizontal clamping plate 613 and located on its lower surface. The second clamping block 65 has a second arc-shaped surface 651, which is used to cooperate with the second positioning pin 42 to prevent the second clamping block 65 from squeezing the second positioning pin 42 and causing damage during the clamping of the die-casting part.

[0051] like Figure 1 As shown, in a specific example provided in this application, there are two second positioning mechanisms 4. The second positioning seats 41 of the two second positioning mechanisms 4 are respectively disposed on the base 1 on both sides of the second pressing seat 61. The two second positioning pins 42 of the two positioning mechanisms 4 increase the positioning points on the die casting, improve the positioning accuracy of the die casting, and ensure the accuracy of subsequent pressing of the die casting.

[0052] like Figure 7 and Figure 8 As shown in a specific example provided in this application, the second clamping mechanism 6 further includes an auxiliary clamping support mechanism 66. The auxiliary clamping support mechanism 66 includes an upper auxiliary clamping arm 661 and a lower auxiliary clamping arm 662. One end of the upper auxiliary clamping arm 661 is connected to the second base plate 64, and the lower auxiliary clamping arm 662 is mounted on the second clamping seat 61. An auxiliary clamping space 663 is provided between the lower auxiliary clamping arm 662 and the upper auxiliary clamping arm 661. Specifically, in this embodiment, the lower auxiliary clamping arm 662 is mounted on the second horizontal clamping plate 613, and a mounting plate 6621 is provided between the lower auxiliary clamping arm 662 and the second horizontal clamping plate 613. Mounting plates with different structures can accommodate lower auxiliary clamping arms 662 at different positions and can be selected and set according to requirements. Understandably, the top of the lower auxiliary clamping arm 662 is used to support the die-cast part, and the upper auxiliary clamping arm 661 rotates with the substrate 64, cooperating with the lower auxiliary clamping arm 662 to clamp the die-cast part within the auxiliary clamping space 663 between the upper auxiliary clamping arm 661 and the lower auxiliary clamping arm 662. In this application, the auxiliary clamping support mechanism 66 increases the clamping points of the die-cast part, improves the stability of the die-cast part clamping, and further ensures the stability of the die-cast part assembly process; the auxiliary clamping support mechanism 66 in this application can also be used to clamp different die-cast parts, further improving the applicability of the assembly system of this application.

[0053] like Figure 1As shown in the specific example provided in this application, the base 1 is equipped with an identification mechanism 7, which is electrically connected to a controller. In actual use, the identification mechanism 7 identifies the unique identifier on the die-casting and feeds the identified identifier back to the controller. The controller determines that the identifier matches the identifier in the assembly data, and controls the upper clamping arm 224, the first clamping mechanism 5, and the second clamping mechanism 6 to clamp the die-casting respectively according to the assembly data. By identifying the identifier on the die-casting, the identification mechanism 7 determines whether the die-casting is the one that needs to be assembled, thus avoiding assembly errors between different types of die-castings.

[0054] like Figure 1 As shown, in a specific example provided in this application, the identification mechanism 7 includes an identification sensor 71 and an identification support 72. The identification support 72, which is electrically connected to the controller, is mounted on the base 1, and the identification sensor 71 is mounted on the identification support 72. It should be noted that the identification mechanism 7 in this embodiment also includes a first auxiliary sensor 73 and a second auxiliary sensor 74 (see...). Figure 6 The first auxiliary sensor 73 is installed on any one of the clamping support mechanisms 22, and the second auxiliary sensor 74 is installed on either the first clamping mechanism 5 or the second clamping mechanism 6. The first auxiliary sensor 73 and the second auxiliary sensor 74 are used to transmit signals indicating that the die-casting part has reached the assembly position to the controller. The controller then controls the clamping support mechanism 22, the first clamping mechanism 5, and the second clamping mechanism 6 to clamp the die-casting part according to the assembly data. Specifically, as shown... Figure 2 As shown, in this embodiment, the first auxiliary sensor 73 is mounted on any one of the support arms 255 via the first sensor support 731, such as... Figure 6 As shown, the second auxiliary sensor 74 is mounted on the lower auxiliary clamping arm 662 via the second sensor support 741. It should be noted that in this embodiment, the marking on the die-cast part is a QR code. The identification sensor 71 identifies the QR code on the die-cast part to obtain the corresponding information of the die-cast part. The first auxiliary sensor 73 and the second auxiliary sensor 74 are specifically position sensors, used to acquire the position signal of the die-cast part reaching the support arm 255 and transmit the position signal to the controller.

[0055] In actual use, the first auxiliary sensor 73 and the second auxiliary sensor 74 detect the position signal of the die-casting part on the support arm 255 and the lower auxiliary clamping arm 662, and feed this position signal back to the controller. The controller activates the clamping cylinder 221, the first drive cylinder 52, and the second drive cylinder 62 according to the assembly data, thereby causing the upper clamping arm 224 to press the die-casting part into the clamping space 227, the first clamping block 55 to press the die-casting part into the first positioning pin seat 321, the second clamping block 65 to press the die-casting part into the second positioning pin seat 421, and the upper auxiliary clamping arm 661 to press the die-casting part into the auxiliary clamping space 663. In this application, the first auxiliary sensor 73 and the second auxiliary sensor 74 improve the clamping accuracy and clamping efficiency of the die-casting part.

[0056] During the assembly of the car body, the assembly data of the die-cast part to be assembled is first selected. Then, the first positioning point and the second positioning point on the die-cast part are respectively placed with the first positioning pin 32 and the second positioning pin 42. The identification sensor 71 identifies the mark on the die-cast part. The controller receives the mark identified by the identification sensor 71 and determines that the mark is the same as the reserved mark in the assembly data of the die-cast part. The controller controls the clamping support mechanism 22 to move in the Z direction through the adjustment mechanism 21 until the support arm 225 in the clamping support mechanism 22 reaches the position set in the assembly data of the die-cast part. At this time, the die-cast part 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-cast part in the assembly data. 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-cast part on the die-cast part support surface to ensure that the die-cast part remains stable during the assembly process. Different car body models have different curved surfaces, and the die-cast parts that assemble the car body also have different inclined curved surfaces. In this application, the controller controls the adjustment mechanism 21 to adjust the clamping support mechanism 22 to different positions through the assembly data reserved for the model, so as to meet the assembly requirements of different models of die-cast parts.

[0057] In other variations of this application, a moving mechanism (not shown in the figure) is provided between the clamping device 2, the first positioning mechanism 3, the second positioning mechanism 4, the first pressing mechanism 5, and the second pressing mechanism 6 and the base 1, respectively, for adjusting the relative positions of the clamping device 2, the first positioning mechanism 3, the second positioning mechanism 4, the first pressing mechanism 5, and the second pressing mechanism 6 on the base 1, so that the large die-casting assembly system of this application can be used for different types of assemblies. This embodiment does not limit the specific structure of the moving mechanism, as long as it enables the clamping device 2, the first positioning mechanism 3, the second positioning mechanism 4, the first pressing mechanism 5, and the second pressing mechanism 6 to move on the base 1.
