[0003] In related technologies, torsion bar springs are usually assembled manually, which requires workers to manually grab, move and adjust them. Since the weight of a torsion bar spring exceeds 30kg, and workers need to observe, hold and adjust the position of the torsion bar spring at the same time during assembly, the labor intensity of workers is high and it is time-consuming and laborious.

[0056] To address the time-consuming and labor-intensive nature of assembling torsion bar springs in related technologies, refer to... Figures 1 to 6 One embodiment of this application provides an assembly auxiliary device for torsion bar springs, including a frame 100, a position adjustment component 200, a lifting mechanism 300, a gripping mechanism 400, and a control component 500. The position adjustment component 200 is slidably mounted on the frame 100 in the horizontal direction; the lifting mechanism 300 is connected to the position adjustment component 200; the gripping mechanism 400 is connected to the lifting mechanism 300 and is used to grip the torsion bar spring 700 to be assembled; the control component 500 is mounted on the gripping mechanism 400 and is electrically connected to the position adjustment component 200, the lifting mechanism 300, and the gripping mechanism 400. The control component 500 is used to drive the position adjustment component 200 to slide in the horizontal direction and rotate in the vertical direction, and to drive the lifting mechanism 300 to lift the gripping mechanism 400, and to drive the gripping mechanism 400 to receive the torsion bar spring 700 to be assembled.

[0057] The frame 100 includes four columns 110. A crossbeam 120 is fixedly connected to the top wall of two columns 110 on the same side of the frame 100. The length direction of the crossbeam 120 is perpendicular to the length direction of the frame 100, and the length direction of the frame 100 is the same as the length direction of the vehicle. A guide rail 130 is fixedly connected between the two crossbeams 120. The length direction of the guide rail 130 is parallel to the length direction of the frame 100. The system also includes a position adjustment component 200, a lifting mechanism 300, a gripping mechanism 400, and a control component 5. The components 00 are arranged vertically from top to bottom below the guide rail 130, while the control component 500 is placed at the bottom. This is to facilitate the worker's operation within the space below the guide rail 130 to operate the control component 500 according to assembly requirements. This allows the worker to control the working state and position of the position adjustment component 200, the lifting mechanism 300, and the gripping mechanism 400 through the control component 500. Consequently, the worker can adjust the installation position of the torsion bar spring 700 without directly contacting it.

[0058] Specifically, when assembling the torsion bar spring 700, the vehicle is located below the guide rail 130, and the worker is also in the activity space below the guide rail 130. By operating the control component 500, the position of the torsion bar spring 700 is adjusted and assembled.

[0059] In this embodiment, the assembly auxiliary device for the torsion bar spring 700 can first control the gripping mechanism 400 to stably hold the torsion bar spring 700 to be assembled via the control component 500, then control the position adjustment component 200 to adjust the position of the torsion bar spring 700 after it is held via the control component 500, and then control the lifting structure to adjust the height of the torsion bar spring 700 so that the torsion bar spring 700 can be installed in a suitable position on the vehicle. This helps to reduce manual operation during the assembly process and eliminates the need for manual handling, thus saving time and effort for workers when assembling the torsion bar spring 700.

[0060] Reference Figures 1 to 3 In some embodiments, the position adjustment assembly 200 includes a slider 210, a rotating shaft 220, a first control element, and a second control element. The slider 210 is slidably connected to the frame 100. The rotating shaft 220 is rotatably connected to the side wall of the slider 210 away from the frame 100 in a vertical direction. The end of the rotating shaft 220 away from the slider 210 is connected to the lifting mechanism 300. The first control element is used to control the slider 210 to slide. The second control element is used to drive the rotating shaft 220 to rotate. Both the second control element and the first control element are electrically connected to the control assembly 500.

[0061] The slider 210 is provided with a guide groove 212, which is slidably connected to the slide rail. The first control component includes four rotating shafts, two conveyor belts 214, and two first micro motors. The four rotating shafts are respectively rotatably mounted on the bottom walls at both ends of the crossbeam 120 and located between two adjacent columns 110. The conveyor belts 214 are wound around the two rotating shafts belonging to different crossbeams 120, and the conveying direction of the conveyor belts 214 is parallel to the length direction of the frame 100. The two first micro motors are respectively mounted on the corresponding crossbeams 120. Both first micro motors are electrically connected to the control component 500, and the control component 500 controls the two first micro motors to start, stop, and rotate in both directions simultaneously. The motor speeds of the two first micro motors are consistent when they are working, thereby ensuring the stability of the slider 210 as it slides back and forth on the slide rail driven by the two conveyor belts 214. A connecting block 216 is fixedly connected to the bottom wall of the slider 210. The second control component includes a second micro motor, which is mounted on the connecting block 216. The motor shaft of the second micro motor is coaxially and fixedly connected to the rotating shaft 220. The second micro motor is electrically connected to the control component 500. The control component 500 can control the motor shaft of the second micro motor to rotate clockwise or counterclockwise, thereby enabling the rotating shaft 220 to drive the torsion bar spring 700 to rotate clockwise or counterclockwise.

[0062] Specifically, when the worker drives the first control component through the control component 500, the slider 210 can be driven to slide back and forth along the length of the guide rail 130 to make a preliminary adjustment to the horizontal position of the gripping mechanism 400; when the worker drives the rotating shaft 220 to rotate through the control component 500, the gripping mechanism 400 can be driven to rotate in the vertical direction, thereby realizing a further adjustment to the horizontal position of the gripping mechanism 400.

[0063] In this embodiment, the cooperation of the slider 210, the rotating shaft 220, the first control component, and the second control component helps to adjust the horizontal position of the torsion bar spring 700 according to actual assembly requirements, and also helps to reduce manual operation, saving time and effort.

[0064] Reference Figures 1 to 3 In some embodiments, the lifting mechanism 300 includes a connecting rod 310, a support rod 320, a connecting seat 330, and a drive assembly 340. One end of the connecting rod 310 is connected to the rotating shaft 220; one end of the support rod 320 is hinged to the end of the connecting rod 310 away from the rotating shaft 220; the connecting seat 330 is hinged to the end of the support rod 320 away from the connecting rod 310, and the connecting seat 330 is connected to the gripping mechanism 400; the drive assembly 340 is used to drive the support rod 320 to rotate around the end connected to the connecting rod 310, so as to drive the connecting seat 330 to lift and lower.

[0065] The connecting rod 310 is arranged vertically, and the top end of the connecting rod 310 is connected to the rotating shaft 220. The bottom end of the connecting rod 310 is connected to the fixing block 312. A through groove 314 is provided through the side wall of the fixing block 312. One end of the support rod 320 is hinged in the through groove 314 through a hinge shaft, and the other end of the support rod 320 is also hinged to the connecting seat 330 through a hinge shaft.

[0066] Specifically, when a worker needs to adjust the height of the gripping mechanism 400 to adjust the height of the torsion bar spring 700, the drive assembly 340 can be used to drive the support rod 320 to rotate around the end hinged to the connecting rod 310, thereby raising and lowering the other end of the support rod 320, and then raising and lowering the gripping mechanism 400 through the linkage of the connecting seat 330.

[0067] In this embodiment, the cooperation of the connecting seat 330, the support rod 320 and the drive component 340 helps to realize the lifting and lowering of the gripping mechanism 400, and helps to reduce manual operation, saving time and effort.

[0068] Reference Figure 2 and Figure 3In some embodiments, the drive assembly 340 includes a push rod 342 and a drive member. One end of the push rod 342 is hinged to the connecting seat 330, and the other end of the push rod 342 is hinged to the connecting rod 310. The push rod 342 and the support rod 320 are parallel to each other, and the push rod 342 and the support rod 320 form a parallelogram. The drive member is used to drive the push rod 342 to rotate around the end connected to the connecting rod 310.

[0069] One end of the push rod 342 is also hinged to the connecting seat 330 via a hinge shaft, and the other end of the push rod 342 is also hinged in the through groove 314 via a hinge shaft.

[0070] Specifically, when the drive member drives the push rod 342 to rotate around the end connected to the connecting rod 310, since one end of the support rod 320 is also hinged to the connecting seat 330 and the other end of the support rod 320 is hinged to the through groove 314, and the length direction of the support rod 320 is parallel to the length direction of the push rod 342, forming a parallelogram, the push rod 342 can drive the support rod 320 to rotate synchronously around the end hinged to the through groove 314, thereby realizing the lifting and lowering of the gripping mechanism 400.

[0071] In this embodiment, the cooperation of push rod 342, support rod 320, connecting seat 330, fixing block 312 and driving component helps to realize the lifting and lowering of connecting seat 330, thereby realizing the lifting and lowering of gripping mechanism 400 driven torsion bar spring 700, and helps to reduce manual operation, saving time and effort.

[0072] Reference Figure 2 and Figure 3 In some embodiments, the driving component includes a connecting plate 346 and a driving cylinder 344. The connecting plate 346 extends horizontally and is disposed on the side wall of the connecting rod 310. The driving end of the driving cylinder 344 is hinged to the end of the connecting plate 346 away from the connecting rod 310, and the end of the driving cylinder 344 away from its own driving end is hinged to the end of the push rod 342 away from the connecting seat 330. The driving cylinder 344 is electrically connected to the control component 500.

[0073] The connecting plate 346 extends horizontally and is fixedly connected to the side wall of the connecting rod 310. The driving end of the driving cylinder 344 can also be hinged to the end of the connecting plate 346 away from the connecting rod 310 via a hinge shaft.

[0074] Specifically, when the drive cylinder 344 drives the movable end, i.e. its own piston rod, to extend, the end of the push rod 342 connected to the connecting seat 330 rises upward, thereby driving the support rod 320 to rise synchronously, thus realizing the synchronous rise of the gripping mechanism 400 driven by the connecting seat 330; when the drive cylinder 344 drives the piston rod to retract, the end of the push rod 342 connected to the connecting seat 330 moves downward, thereby driving the support rod 320 to move downward synchronously, thus realizing the synchronous lowering of the gripping mechanism 400 driven by the connecting seat 330.

[0075] In this embodiment, the driving cylinder 344 applies power to the end of the push rod 342 away from the connecting seat 330. The structure is simple, which makes it easy to lift and lower the gripping mechanism 400. It also eliminates the need for manual operation by workers, saving time and effort.

[0076] Reference Figure 1 and Figure 2 In some embodiments, the gripping mechanism 400 includes a base plate 410, a support base 420 and two support blocks 430. The control component 500 is disposed at one end of the base plate 410; the support base 420 is disposed at the other end of the base plate 410; the two support blocks 430 are detachably disposed on the support base 420, and the support blocks 430 are used to stably support the torsion bar spring 700 to be assembled.

[0077] The support base 420 and support blocks 430 are used to support the torsion spring 700. Each support block 430 has a receiving groove 432 on its top wall for receiving the torsion spring 700; the longitudinal cross-sectional shape of the receiving groove 432 is V-shaped. The support blocks 430 are detachably connected to the support base 420 by bolts 424, allowing workers to select a suitable size support block 430 according to the dimensions of the torsion spring 700, thereby improving the adaptability and flexibility of the gripping mechanism 400 and the assembly auxiliary device for the torsion spring. In addition, reinforcing ribs 422 are fixedly connected to the bottom wall of the support base 420 to enhance its support capacity for the torsion spring 700.

[0078] Specifically, workers can pre-select appropriate support blocks 430 based on the dimensions of a batch of torsion springs 700 to be assembled, and connect the support blocks 430 to the support base 420 using bolts 424. Additionally, workers can adjust the height of the two support blocks 430 using bolts 424, causing the torsion springs 700, which are received in the receiving grooves 432, to tilt at a certain angle to accommodate the installation of the torsion springs 700.

[0079] In this embodiment, the cooperation of the base plate 410, the support base 420, and the two support blocks 430 helps to achieve stable support for the torsion bar spring 700. Furthermore, by placing the control component 500 on the lowermost base plate 410, it is convenient for workers standing on the ground to adjust the working state of the assembly aid for the torsion bar spring, thereby further improving the ease of assembly for workers and contributing to overall convenience.

[0080] Reference Figures 4 to 6 In some embodiments, the support base 420 is movably disposed at the end of the substrate 410 away from the control component 500, and the gripping mechanism 400 further includes a telescopic component 440 for driving the support base 420 to reciprocate toward the substrate 410, the telescopic component 440 being electrically connected to the control component 500.

[0081] The support base 420 is configured to be connected to the basic movement, making it easier for workers to further adjust the position of the torsion bar spring 700.

[0082] Specifically, when the worker needs to further adjust the position of the torsion bar spring 700 in the horizontal direction, the telescopic component 440 can be used to control the support base 420 to move towards the side closer to the base plate 410 or away from the base plate 410, thereby achieving the adjustment of the horizontal position of the support base 420.

[0083] Reference Figures 4 to 6 In some embodiments, the telescopic assembly 440 includes a fixed rod 442, a telescopic rod 444, and a power component. One end of the fixed rod 442 is connected to the base plate 410, and a guide groove 212 is provided on the end wall of the fixed rod 442 away from the base plate 410. One end of the telescopic rod 444 is slidably connected in the guide groove 212, and the other end of the telescopic rod 444 is connected to the side wall of the support base 420. The power component is disposed in the fixed rod 442 and is used to drive the telescopic rod 444 to slide along the guide groove 212. The power component is electrically connected to the control assembly 500.

[0084] The power component may include a screw and a drive motor. The screw is rotatably connected in the guide groove 212. One end of the screw is threadedly connected to the telescopic rod 444, and the other end of the screw is coaxially connected to the motor shaft of the drive motor. The drive motor is electrically connected to the control component 500. The longitudinal section of the guide groove 212 is rectangular.

[0085] Specifically, when the worker needs to adjust the horizontal position of the torsion bar spring 700, the control component 500 controls the forward and reverse rotation of the drive motor, so that under the threaded feed of the screw, the telescopic rod 444 slides outward or inward into the guide groove 212.

[0086] In this embodiment, the telescopic rod 444 is reciprocated within the guide groove 212 by a power component, thereby enabling fine adjustment of the horizontal position of the torsion bar spring 700.

[0087] Reference Figure 1 and Figure 6 In some embodiments, the control component 500 includes a controller, which includes a control panel 510 and a plurality of control buttons 520. The controller's chip is loaded with a control program, and the control buttons 520 are located on the control panel 510, so that workers can adjust the working status of the aforementioned position adjustment component 200, lifting mechanism 300 and gripping mechanism 400.

[0088] Reference Figure 1 and Figure 2 In some embodiments, the gripping mechanism 400 further includes a position adjustment component 600 disposed between the substrate 410 and the connector 330, and the position adjustment component 600 is also used to adjust the position of the support base 420.

[0089] Specifically, the position fine-tuning component 600 is used to further fine-tune the horizontal position of the torsion bar spring 700, and the position fine-tuning component 600 can drive the support base 420 to rotate 360° in the horizontal plane.

[0090] Reference Figure 1 and Figure 2 In some embodiments, the position fine-tuning component 600 includes a rotating shaft 610 and a connecting rod 620. The rotating shaft 610 is hinged to the connecting seat 330 and electrically connected to the control component 500. One end of the connecting rod 620 is connected to the rotating shaft 610, and the other end of the connecting rod 620 is connected to the substrate 410.

[0091] The rotating shaft 610 is rotatably connected to the bottom wall of the connecting seat 330 in a vertical direction. The longitudinal section of the connecting rod 620 is L-shaped, and the other end of the connecting rod 620 can be detachably connected to the base plate 410 through the cooperation of the mounting block and screws. In addition, the connecting rod 620 can be a flexible connecting rod 620. An operating handle 450 is also fixedly connected to the base plate 410, and the control component 500 is set close to the operating handle 450.

[0092] Specifically, workers can drive the rotating shaft 610 to rotate by operating the corresponding control button 520 on the control panel 510. This causes the rotating shaft 610 to drive the base plate 410 to rotate synchronously via the connecting rod 620, thereby achieving further adjustment of the position of the base plate 410 and the torsion spring 700. Additionally, workers can also deform the flexible connecting rod 620 by turning the operating handle 450 to further precisely fine-tune the position of the torsion spring 700. This helps to further improve the flexibility of the assembly auxiliary device for torsion springs in this application, thus saving workers time and effort when assembling the torsion spring 700 and improving assembly efficiency.

[0093] When using the torsion bar spring assembly auxiliary device of this application, the worker can first select a suitable support block 430 according to the size of a certain batch of torsion bar springs 700, and then, according to the actual assembly requirements, control the gripping mechanism 400 to stably hold the torsion bar spring 700 to be assembled through the control component 500. Then, control the position adjustment component 200 to adjust the position of the torsion bar spring 700 after it is held through the control component 500, and control the lifting structure to adjust the height of the torsion bar spring 700 so that the torsion bar spring 700 can be installed in a suitable position on the vehicle. This helps to reduce manual operation in the assembly process and eliminates the need for manual handling, thus saving time and effort for workers when assembling the torsion bar spring 700.
