Description

Technical Field

[0001] The present invention relates to the technical field of automobile subframe assembly, in particular to an assembly tool for a new energy automobile subframe assembly. Background Art

[0002] The subframe is an important component in the vehicle structure, mainly used to support the front and rear axles and suspension system. The subframe is connected by combining the front and rear axle suspension rocker mechanisms to form an axle assembly, which is then installed on the vehicle body. This design makes the vehicle structure more stable and improves driving comfort.

[0003] Since the subframe assembly usually integrates key components such as suspension, steering, and motor, it is heavy and has many connection points with the vehicle body. Therefore, when installing the subframe assembly to the vehicle body, it is necessary to use assembly tooling to assist in the installation.

[0004] As a key component of the automobile chassis, the subframe has diverse specifications. New energy vehicles of different models and configurations are equipped with subframes that often differ significantly in size and shape. Traditional assembly tooling usually adopts a fixed structure, and the position and size of its clamping components are pre-set for a certain fixed subframe assembly, lacking flexibility and adjustability. As a result, when faced with subframes of different specifications, traditional tooling is unable to meet their fixing requirements, resulting in a significant reduction in assembly efficiency.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention can meet the fixing requirements of subframe bodies of different specifications by setting the support assembly and the clamping assembly. By turning the adjustment knob to drive the adjustment screw to rotate, the position between the two sets of clamping assemblies can be accurately adjusted. This design allows the tooling to adapt to subframes of different sizes and shapes, meeting diverse production needs.

[0026] At the same time, multiple groups of elastic clamping plates and sliding blocks are initially in a horizontal state. After the driving motor drives the cam rod to rotate, the trigger rod drives the synchronous slider downward under the action of the tension spring, prompting the cam plate to rotate, so that the elastic clamping plate and the sliding block are perpendicular and gradually contact the side of the sub-frame body. In this process, the sliding block slides outward along the adjustment cavity through the sliding rod under the action of the thrust of the sub-frame body and the flipping force of the elastic clamping plate, thereby realizing automatic adjustment of the distance between the two groups of sliding blocks on the fixed block, thereby effectively clamping the side edges of the sub-frame body of different widths, ensuring the accuracy and stability of the clamping.

[0027] 2. In the present invention, after the sub-frame body is placed, the driving motor drives the gear set to rotate, so that the cam rod is disengaged from the pushing block, and the trigger rod moves downward under the action of the rebound force of the tension spring, driving the cam plate to rotate, thereby causing the elastic clamping plate to synchronously rotate to be perpendicular to the adjacent sliding block and in close contact with the side of the sub-frame body. Under the combined action of the thrust of the sub-frame body and the turning force of the elastic clamping plate, the sliding block slides outward along the adjustment cavity, so that the distance between the two groups of sliding blocks on the fixed block becomes larger, thereby achieving stable clamping of the sides of the sub-frame body with different widths. This clamping method can automatically adjust the clamping force and range according to the actual situation of the sub-frame body, ensuring that the sub-frame body will not shake or deviate during the assembly process, providing a stable and reliable foundation for the assembly work, and effectively ensuring the assembly quality and the safety of the operator.

[0028] 3. In the present invention, during assembly, the drive motor is restarted to open the elastic clamping plate. Simultaneously, the rotation of the drive plate drives the adjustment frame upward, thereby moving the lifting assembly upward. When the trigger plate at the top of the trigger lever contacts the touch switch, multiple sets of lifting cylinders are activated, driving the lifting plate upward, precisely lifting the subframe body into contact with the vehicle body. This synchronous lifting and precise positioning design ensures accurate docking of the subframe body with the vehicle body, reduces manual adjustment errors and time, and improves assembly accuracy and efficiency.

[0029] At the same time, since the lifting assembly has been initially moved upward and precisely positioned, the distance between the vehicle body and the subframe body is now small, and the upward movement range of the lifting plate is also effectively controlled. This precise jacking design enables the subframe body to be docked with the vehicle body smoothly and accurately, avoiding assembly difficulties caused by excessive or insufficient jacking. Even if the subframe body is not further fixed, due to its close distance to the vehicle body and precise docking, no large offset will occur, further improving assembly efficiency and docking quality.

The first synchronization rod 27 is slidably connected in the two limiting grooves 24, and the ends of the two groups of first connecting rods 25 away from the bottom plate 21 are hinged to the first synchronization rod 27 on the top plate 22, and the ends of the two groups of second connecting rods 26 away from the top plate 22 are hinged to the first synchronization rod 27 on the bottom plate 21. A driving cylinder 23 is also fixedly connected to the bottom plate 21, and the output end of the driving cylinder 23 is fixed to the first synchronization rod 27 on the bottom plate 21;

[0047] Specifically, when assembling the sub-frame body, the sub-frame body is first conveyed to the support assembly 3 by a conveyor, the clamping assembly 4 is adjusted by the support assembly 3 so that the position of the clamping assembly 4 is adapted to the sub-frame body, and then the driving assembly 6 is started to drive the clamping assembly 4 to fix the sub-frame body;

[0048] After being fixed, the driving cylinder 23 is started. The output end of the driving cylinder 23 pulls the first synchronization rod 27 in the upper limit groove 24 of the bottom plate 21 to slide, so that the end of the second connecting rod 26 close to the top plate 22 drives the top plate 22 to lift upward, so that the first synchronization rod 27 in the upper limit groove 24 of the top plate 22 slides synchronously, and one end of the first connecting rod 25 follows the second connecting rod 26 to lift synchronously, so that the top plate 22 drives the support assembly 3 and the subframe on the support assembly 3 to move upward and contact the vehicle body for assembly;

[0049] When the sub-frame moves to the bottom of the vehicle body, the driving cylinder 23 is closed, the lifting assembly 5 and the driving assembly 6 are started, and the clamping assembly 4 is retracted by the driving assembly 6 to prevent the clamping assembly 4 from affecting the assembly work. The sub-frame is lifted upward by the lifting assembly 5 until it contacts the vehicle body for assembly work. During assembly, after the four corners of the sub-frame body are fixed to the vehicle body, the driving cylinder 23 can be controlled to start, so that the driving cylinder 23 drives the top plate 22 to move downward, and drives the support assembly 3 to move downward, pushing the assembly frame 1 to move the lifting assembly 2 and the support assembly 3 out from under the vehicle body to avoid affecting subsequent assembly work.

[0050] In this embodiment, the support assembly 3 includes a support frame 31, the support frame 31 is fixedly connected to the top of the lifting assembly 2, a first support plate 32 is slidably connected to the support frame 31, and a second support plate 33 is fixedly connected to the bottom of the first support plate 32, two groups of first displacement grooves 34 are opened on the first support plate 32, and the two groups of clamping assemblies 4 are slidably connected to the first displacement grooves 34, and two groups of second displacement grooves 39 are opened on the second support plate 33, and the two groups of second displacement grooves 39 are respectively located on one side of the two groups of first displacement grooves 34, the driving assembly 6 is arranged in the two groups of second displacement grooves 39, and two groups of adjustment grooves 35 are also opened on the first support plate 32. The two adjusting screws 36 are rotatably connected in the group adjusting slots 35, and the two groups of adjusting screws 36 are respectively connected to the two groups of clamping assemblies 4. The two sides of the first support plate 32 are also rotatably connected with adjusting knobs 37. The ends of the two adjusting knobs 37 close to the first support plate 32 are respectively fixed to the two groups of adjusting screws 36. The bottom of the second support plate 33 is also fixedly connected to multiple groups of adjusting frames 38, and the ends of the multiple groups of adjusting frames 38 close to the inner wall of the support frame 31 all slide on the inner wall of the support frame 31. The multiple groups of adjusting frames 38 are each provided with a pushing groove on the side away from the support frame 31, and the output ends of the drive assembly 6 are respectively slidably engaged in the pushing grooves on the multiple groups of adjusting frames 38;

[0051] Specifically, initially, the clamping assembly 4 is in an open state, and the first support plate 32 extends from the support frame 31. When in use, the two adjusting knobs 37 are first rotated, so that the adjusting knobs 37 drive the two adjusting screws 36 to rotate, so that the two groups of clamping assemblies 4 slide in the two groups of first displacement slots 34 and second displacement slots 39, and then the positions of the two groups of clamping assemblies 4 are adjusted. The sub-frame body to be assembled is placed on the lifting assembly 5, and the driving assembly 6 is started, so that the driving assembly 6 drives the clamping assembly 4 to close. During the closing process, the clamping assembly 4 clamps both sides of the sub-frame body to fix the sub-frame body.

[0052] When the driving assembly 6 is started to drive the clamping assembly 4 to fix the sub-frame body, the driving assembly 6 simultaneously pushes the multiple groups of adjustment frames 38 downward, so that the multiple groups of adjustment frames 38 drive the second support plate 33 and the first support plate 32 to move downward and reset, so that the bottom of the sub-frame body contacts the top of the support frame 31. After fixation, the entire device is pushed to the bottom of the vehicle body by the assembly frame 1, and the lifting assembly 2 is started to lift the support assembly 3 and the sub-frame body upward by the lifting assembly 2 to carry out the assembly work.

[0053] In this embodiment, the two groups of clamping assemblies 4 include two groups of fixed blocks 41, which are slidably connected to the two groups of first displacement grooves 34 respectively. Two groups of sliding blocks 42 are slidably connected to the two groups of fixed blocks 41. The ends of the two groups of sliding blocks 42 away from each other are hinged with elastic clamping plates 43 for fixing the sub-frame body through a rotating shaft. The top of each group of fixed blocks 41 is also fixedly connected to a partition plate 49, and both sides of the partition plate 49 are fixedly connected to a return spring. The other ends of the multiple return springs are respectively fixed to the adjacent sliding blocks 42. Two groups of adjustment cavities 45 are opened on both sides of each group of fixed blocks 41, and the bottom of each group of sliding blocks 42 is fixedly connected to two groups of slide rods 4 6. Multiple groups of sliding rods 46 are respectively slidably connected to adjacent adjustment chambers 45. The clamping assembly 4 also includes two groups of second synchronization rods 44. The two groups of second synchronization rods 44 are located between the two groups of fixed blocks 41, and the two ends of the two groups of second synchronization rods 44 are respectively fixed to the rotating shafts of adjacent elastic clamping plates 43. A connecting rod is also fixedly connected between the two groups of fixed blocks 41, and a threaded hole is opened in the middle of the connecting rod. The connecting rod is threadedly connected to the adjacent adjustment screw 36 through the threaded hole. A cam plate 47 is also fixedly connected to the side of each group of elastic clamping plates 43 away from the second synchronization rod 44. The bottom of each group of cam plates 47 is hinged with a synchronization slider 48. Multiple groups of synchronization sliders 48 are all slidably connected to the drive assembly 6;

[0054] Specifically, when fixing the sub-frame body, first turn the adjusting knob 37, which drives the adjusting screw 36 to rotate, so that the adjusting screw 36 drives the connecting rod to move, and the connecting rod drives the adjacent fixing block 41 to slide in the first displacement groove 34, thereby adjusting the position between the two sets of clamping assemblies 4. After the adjustment is completed, the sub-frame body is placed on the lifting assembly 5. At this time, the multiple sets of elastic clamping plates 43 are all in a horizontal state with the adjacent sliding blocks 42;

[0055] After the sub-frame body is placed, the driving assembly 6 is started, and the driving assembly 6 drives the synchronous slider 48 to move downward. When the synchronous slider 48 moves downward, it drives one end of the cam plate 47 to move downward, so that the end of the cam plate 47 fixed to the elastic clamping plate 43 rotates, and the elastic clamping plate 43 rotates synchronously until it is perpendicular to the adjacent sliding block 42;

[0056] When the elastic clamping plate 43 rotates, it gradually contacts the side of the sub-frame body. Under the action of the thrust of the sub-frame body and the turning force of the elastic clamping plate 43, the sliding block 42 slides outward along the adjustment cavity 45 via the sliding rod 46, thereby increasing the distance between the two sets of sliding blocks 42 on the fixed block 41, thereby achieving the clamping of the side edges of the sub-frame body with different widths.

[0057] When the sub-frame body is moved to the bottom of the vehicle body for assembly, the driving assembly 6 is started again to drive the synchronous slider 48 to move upward. When the synchronous slider 48 moves upward, it pushes the cam plate 47 to flip over, so that the cam plate 47 drives the elastic clamping plate 43 to flip open, so that the elastic clamping plate 43 is once again in a horizontal state with the sliding block 42. When the elastic clamping plate 43 is no longer fixed to the sub-frame body, the two sets of sliding blocks 42 are simultaneously reset under the drive of the reset spring on the partition plate 49.

[0058] In this embodiment, the driving assembly 6 includes two groups of trigger rods 61, and the two groups of trigger rods 61 are respectively slidably connected to the adjacent second displacement grooves 39. The bottoms of the two groups of trigger rods 61 are fixedly connected to pushing blocks 62, and the bottoms of the pushing blocks 62 pass through the bottom of the second displacement grooves 39 and extend to the bottom of the second support plate 33. The tops of the two groups of trigger rods 61 are provided with sliding grooves 63, and multiple groups of synchronous sliders 48 are respectively slidably connected to the adjacent sliding grooves 63. The bottoms of both ends of the two groups of trigger rods 61 are fixedly connected to tension springs 65, and the other ends of the multiple groups of tension springs 65 are fixedly connected to the adjacent adjustment frames 38. The tops of both ends of the two groups of trigger rods 61 are also fixedly connected to trigger plates 64. The inner walls on both sides of the two groups of second displacement grooves 39 are fixedly connected with touch switches compatible with the multiple groups of trigger plates 64. 64 cooperates with multiple groups of touch switches to control the opening and closing of the lifting assembly 5. The driving assembly 6 also includes a driving motor 66 and a gear box 67. The driving motor 66 and the gear box 67 are fixedly connected to the support frame 31. A gear set is rotatably connected in the gear box 67. The output end of the driving motor 66 is fixed to the gear set in the gear box 67. The output end of the gear set in the gear box 67 is fixedly connected to two groups of cam rods 68. The two groups of cam rods 68 are respectively located below the two groups of second displacement grooves 39, and both ends of the two groups of cam rods 68 pass through the gear box 67 and extend to the outside of the gear box 67. The extended ends of the two groups of cam rods 68 are fixedly connected to the driving disk 69. The side of the multiple groups of driving disks 69 away from the cam rods 68 is fixedly connected to an eccentric push wheel, and the multiple groups of eccentric push wheels are respectively slidably engaged in the pushing grooves on the adjacent adjustment frames 38;

[0059] Specifically, after the sub-frame body is placed on the lifting assembly 5, the drive motor 66 is first started. The drive motor 66 drives the gear set in the gear box 67 to rotate, and the two sets of cam rods 68 are rotated simultaneously through the gear set transmission. Initially, the cam rod 68 contacts the pushing block 62, so that the trigger rod 61 is in a jacking state, and the tension spring 65 at the bottom of the trigger rod 61 is simultaneously in a tension state. When the cam rod 68 rotates, the cam rod 68 first rotates to disengage from the pushing block 62. Driven by the rebound force of the tension spring 65, the trigger rod 61 moves downward and pulls the synchronous slider 48 and the cam plate 47, so that the elastic clamping plate 43 flips over to fix the side of the sub-frame body.

[0060] When the cam rod 68 rotates, it simultaneously drives the multiple sets of drive plates 69 to rotate, so that the eccentric push wheels on the multiple sets of drive plates 69 push the adjustment frame 38 downward, so that the first support plate 32 and the second support plate 33 move downward, so that the sub-frame body falls on the support frame 31;

[0061] When the sub-frame body is moved to the bottom of the vehicle body for assembly, the drive motor 66 is started again. The drive motor 66 drives the cam rod 68 to rotate, so that the cam rod 68 pushes the pushing block 62 to move upward, and the trigger rod 61 moves upward to lift the synchronous slider 48 and the cam plate 47, so that the elastic clamping plate 43 is flipped open and no longer fixes the sub-frame body. At the same time, the drive plate 69 rotates to drive the adjustment frame 38 to move upward, so that the first support plate 32, the second support plate 33 and the lifting assembly 5 move upward, so that the adjustment knob 37 is exposed for subsequent adjustment work.

[0062] In this embodiment, the lifting assembly 5 includes two groups of fixed plates 51, both of which are fixedly connected to the top of the first support plate 32, and both groups of fixed plates 51 are provided with sliding grooves 53 for the clamping assembly 4 to move. A lifting plate 52 is slidably connected between the two groups of fixed plates 51. The lifting assembly 5 also includes multiple groups of lifting cylinders 54, which are respectively located at the bottom of both ends of the second support plate 33. A connecting frame is fixedly connected between the two groups of lifting cylinders 54 on the same side, and the two ends of the connecting frame are respectively fixed to the adjacent adjustment frames 38. The output ends of the multiple groups of lifting cylinders 54 all pass through the second support plate 33 and the first support plate 32 and are fixed to the lifting plate 52 on the first support plate 32.

[0063] Specifically, when the trigger rod 61 moves upward to drive the elastic clamping plate 43 to open and no longer fix the sub-frame body, the trigger plate 64 on the top of the trigger rod 61 simultaneously contacts the touch switch in the second displacement groove 39, so that the multiple sets of lifting cylinders 54 are activated. The multiple sets of lifting cylinders 54 drive the lifting plate 52 to move upward, so that the lifting plate 52 lifts the sub-frame body and contacts the vehicle body. Since the distance between the vehicle body and the sub-frame body is small at this time, the upward movement range of the lifting plate 52 is also small. At this time, even if the sub-frame body is not fixed, the sub-frame body will not have a large displacement.

[0064] When the sub-frame body contacts the vehicle body, the four corners of the sub-frame body are first fixed to the vehicle body. After fixing, the lifting cylinder 54 drives the lifting plate 52 to retract, and then pushes the assembly frame 1 to move the device out from under the vehicle body, and then the assembly work can continue.

[0065] The working principle of the present invention is:

[0066] When fixing the sub-frame body, first turn the adjusting knob 37, which drives the adjusting screw 36 to rotate, so that the adjusting screw 36 drives the connecting rod to move, and the connecting rod drives the adjacent fixing block 41 to slide in the first displacement groove 34, thereby adjusting the position between the two sets of clamping assemblies 4. After the adjustment is completed, the sub-frame body is placed on the lifting plate 52. At this time, the multiple sets of elastic clamping plates 43 are all in a horizontal state with the adjacent sliding blocks 42;

[0067] After the sub-frame body is placed, the drive motor 66 is started, and the drive motor 66 drives the gear set in the gear box 67 to rotate, and the two sets of cam rods 68 are rotated at the same time through the gear set transmission. Initially, the cam rod 68 contacts the pushing block 62, so that the trigger rod 61 is in a jacking state, and the tension spring 65 at the bottom of the trigger rod 61 is in a stretched state at the same time. When the cam rod 68 rotates, the cam rod 68 first rotates to disengage from the pushing block 62, and the trigger rod 61 moves downward under the drive of the rebound force of the tension spring 65, and pulls the synchronous slider 48 downward, and the synchronous slider 48 When moving downward, one end of the cam plate 47 is driven downward, causing the end of the cam plate 47 fixed to the elastic clamping plate 43 to rotate, causing the elastic clamping plate 43 to rotate synchronously until it is perpendicular to the adjacent sliding block 42. When the elastic clamping plate 43 rotates, it gradually contacts the side of the sub-frame body. Under the action of the thrust of the sub-frame body and the turning force of the elastic clamping plate 43, the sliding block 42 is caused to slide outward along the adjustment cavity 45 through the sliding rod 46, so that the distance between the two groups of sliding blocks 42 on the fixed block 41 becomes larger, so as to achieve clamping of the side edges of the sub-frame body with different widths.

[0068] When the cam rod 68 rotates, it simultaneously drives the multiple sets of drive plates 69 to rotate, so that the eccentric push wheels on the multiple sets of drive plates 69 push the adjustment frame 38 downward, so that the first support plate 32 and the second support plate 33 move downward, so that the sub-frame body falls on the support frame 31;

[0069] After the sub-frame body is fixed, push the assembly frame 1 to move the sub-frame body to the bottom of the vehicle body to prepare for assembly work;

[0070] When assembling, the drive motor 66 is started again to rotate the cam rod 68, which lifts the pushing block 62 to enable the trigger rod 61 to drive the synchronous slider 48 to move upward. When the synchronous slider 48 moves upward, it pushes the cam plate 47 to flip over, so that the cam plate 47 drives the elastic clamping plate 43 to flip open, so that the elastic clamping plate 43 is once again in a horizontal state with the sliding block 42. When the elastic clamping plate 43 is no longer fixed to the sub-frame body, the two sets of sliding blocks 42 are reset at the same time under the drive of the return spring on the partition plate 49. At the same time, the drive plate 69 rotates to drive the adjustment frame 38 to move upward, so that the first support plate 32, the second support plate 33 and the lifting assembly 5 move upward, so that the adjustment knob 37 is exposed for subsequent adjustment.

[0071] When the trigger rod 61 moves upward, driving the elastic clamping plate 43 to open and no longer fix the sub-frame body, the trigger plate 64 on the top of the trigger rod 61 simultaneously contacts the touch switch in the second displacement slot 39, activating the multiple sets of lifting cylinders 54. The multiple sets of lifting cylinders 54 drive the lifting plate 52 to move upward, causing the lifting plate 52 to lift the sub-frame body and contact the vehicle body. Since the distance between the vehicle body and the sub-frame body is small at this time, the upward movement range of the lifting plate 52 is also small. At this time, even if the sub-frame body is not fixed, the sub-frame body will not cause significant displacement.

[0072] When the sub-frame body contacts the vehicle body, the four corners of the sub-frame body are first fixed to the vehicle body. After fixing, the lifting cylinder 54 drives the lifting plate 52 to retract, and then pushes the assembly frame 1 to move the device out from under the vehicle body, and then the assembly work can continue.

The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection part.
