[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0022] Figure 1 This is a schematic diagram of the structure of the vehicle front subframe assembly device in an embodiment of this utility model; Figure 2 This is a schematic diagram of the structure of the vehicle front subframe assembly device in the front view direction in an embodiment of this utility model; Figure 3 This is a schematic diagram of the structure of the vehicle front subframe assembly device in the side view direction in an embodiment of this utility model; Figure 4 This is a schematic diagram of the structure of the vehicle front subframe assembly device in a top view according to an embodiment of this utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the automotive front subframe assembly device provided by this utility model includes a base 10 and a support and positioning structure 20 disposed on the base 10. The support and positioning structure 20 can support and position the front subframe welded assembly 1 and the left and right control arms 2. It can support and limit the front subframe welded assembly 1 and other components during the assembly process, ensuring the positional accuracy of the front subframe welded assembly 1 and the left and right control arms 2 during the assembly process. It can meet the positional accuracy requirements of each component in the modular assembly of the front subframe welded assembly 1, which is conducive to improving the assembly quality and assembly efficiency of the front subframe welded assembly 1.

[0024] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, the base 10 includes a base plate 11, a support plate 12, a rotating shaft 13, and a rotating shaft seat 14. The rotating shaft seat 14 is mounted on the base plate 11. One end of the rotating shaft 13 is rotatably inserted into the rotating shaft seat 14, and the other end of the rotating shaft 13 is connected to the support plate 12, so that the support plate 12 can be rotatably mounted on the base plate 11. This facilitates the subsequent assembly of the front subframe welding assembly 1, the left and right control arms 2, and other components, and helps to improve the efficiency of sub-assembly.

[0025] The support plate 12 is provided with a locking pin 15, which is movably inserted into the support plate 12. The bottom plate 11 is provided with a locking hole that matches the locking pin 15. After the support plate 12 is rotated to a specific angle, the locking pin 15 is inserted into the locking hole, locking the support plate 12 and the bottom plate 11. This maintains the stability of the support plate 12 during the modular assembly of the front subframe welding assembly 1, which is beneficial to improving the positional accuracy requirements of each component during the modular assembly of the front subframe welding assembly 1, and also helps to improve the assembly quality and efficiency of the front subframe welding assembly 1.

[0026] like Figure 1 As shown, the support and positioning structure 20 includes a subframe support assembly 21. The subframe support assembly 21 includes a first mounting plate 211, a first mounting seat 212, a first support column 213, and a first support block 214. The first mounting plate 211 is connected to the support plate 12. Two first mounting plates 211 are respectively disposed on both sides of the support plate 12. The first mounting seat 212 is disposed on the first mounting plate 211. One end of the first support column 213 is connected to the first mounting seat 212, and the other end of the first support column 213 is connected to the first support block 214. The two sets of subframe support assemblies 21 are respectively disposed on both sides of the support plate 12. The first support block 214 abuts against the front subframe welded assembly 1, so that the subframe support assembly 21 can support and limit the front subframe welded assembly 1 in the Z direction.

[0027] like Figure 1As shown, the support positioning structure 20 also includes a control arm support assembly 22. The control arm support assembly 22 includes a second mounting base 221, a second support column 222, and a second support block 223. The second mounting base 221 is disposed on the first mounting plate 211. One end of the second support column 222 is connected to the second mounting base 221, and the other end of the second support column 222 is connected to the second support block 223. The two sets of control arm support assemblies 22 are respectively disposed on the two first mounting plates 211 on both sides of the support plate 12. The control arm support assembly 22 is located on the side of the subframe support assembly 21 away from the support plate 12. The second support block 223 abuts against the left and right control arms 2, so that the control arm support assembly 22 can support the left and right control arms 2 and limit them in the X / Y / Z directions. This ensures the initial angle design of the left and right control arms 2 during assembly and avoids the problem of directional deviation and rubber bushing tearing caused by the initial angle deviation of the left and right control arms 2 during driving. This is beneficial to improving the assembly quality and assembly efficiency of the front subframe welding assembly.

[0028] like Figure 1 As shown, the support positioning structure 20 also includes a limiting and pressing assembly 23. The limiting and pressing assembly 23 includes a third mounting base 231, a third support column 232, and a third support block 233. The third mounting base 231 is disposed on the first support plate 211. One end of the third support column 232 is connected to the third mounting base 231, and the other end of the third support column 232 is connected to the third support block 233. The third support block 233 is provided with a limiting and pressing flange 234. The third support block 233 and the limiting and pressing flange 234 can fix the front subframe welding assembly 1 and related components such as the left and right control arms 2 in the Z-direction during the assembly and fixing process, ensuring that the front subframe welding assembly will not shift when the related components are assembled and fixed, which is beneficial to improving the assembly quality and assembly efficiency of the front subframe welding assembly.

[0029] like Figure 1 As shown, the support positioning structure 20 also includes a positioning pin assembly 24. The positioning pin assembly 24 includes a second mounting plate 241, a positioning seat 242, a positioning pin 243, and a positioning pin 244. The second mounting plate 241 is connected to the support plate 12. The two second mounting plates 241 are respectively disposed on both sides of the support plate 12. The positioning seat 242 is disposed on the second mounting plate 241. One end of the positioning pin 243 is connected to the positioning seat 242, and the other end of the positioning pin 243 is connected to the positioning pin 244. The front subframe welding assembly 1 is provided with a positioning pin hole that matches the positioning pin 244. The positioning pin 244 passes through the positioning pin hole, so that the positioning pin 243 and the positioning pin 244 can support the front subframe welding assembly 1 and limit its movement in the X / Y / Z directions.

[0030] Figure 5This is a schematic diagram of the front subframe welding assembly and the left and right control arms mounted on the automotive front subframe subassembly device in an embodiment of this utility model.

[0031] like Figure 5 As shown, the front subframe welding assembly 1 is supported and limited in the X / Y / Z directions by the subframe support assembly 21 and the positioning pin assembly 24. The left and right control arms 2 are supported and limited in the X / Y / Z directions by the control arm support assembly 22. This allows the control arm support assembly 22 to support and limit the left and right control arms 2 in the X / Y / Z directions, ensuring the initial angle design of the left and right control arms 2 during assembly. This avoids directional deviation and rubber bushing tearing caused by the initial angle deviation of the left and right control arms 2 during driving, which is beneficial to improving the assembly quality and efficiency of the front subframe welding assembly. The limiting and clamping assembly 23 can fix the front subframe welding assembly 1 and the left and right control arms 2 and other related components in the Z direction during the assembly and fixing process, ensuring that the front subframe welding assembly will not shift when the related components are assembled and fixed. This is beneficial to improving the assembly quality and efficiency of the front subframe welding assembly.
