The utility model can adjust not only the height of the operating table but also the inclination angle of the operating table by setting the adjustment component, so as to facilitate the assembly operation; by setting the adsorption component and the rotating part, the operator does not need to walk around the operating table during the assembly process, which saves time and effort and has high assembly efficiency.

[0004] When using the above technology, it was found that the following technical problems exist in the prior art: the above device can flexibly adjust the position of the operating table when assembling the car door, but there is no further design on the operating table for fixing the car door, and the car door cannot be effectively fixed on the operating table. When adjusting the inclination angle of the operating table or rotating the operating table during the assembly process, the car door may accidentally fall off the operating table, increasing the operational risk. Therefore, we have made improvements to this and proposed a flexible assembly tool for car doors. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the vehicle door cannot be effectively fixed on the operating table. When the tilt angle of the operating table is adjusted or the operating table is rotated during the assembly process, the vehicle door may accidentally fall off the operating table, increasing the operating risk.

Two driving blocks are symmetrically arranged on the first screw rod, and the clamping rod is installed on the driving block;

[0008] The adsorption component comprises a vacuum suction cup, which is arranged on a working bottom plate between two driving blocks through a liftable connecting piece.

[0009] Preferably, one end of the first screw rod passes through the working base plate and is connected to the output shaft of the first servo motor, and the first servo motor is mounted on the working base plate through a motor mounting bracket.

[0010] Preferably, the clamping assembly further comprises two bottom support plates, the two bottom support plates are respectively mounted on the two clamping rods, buffer pads are mounted on the bottom support plates, and the upper clamping piece is mounted on the clamping rod.

[0011] Preferably, the upper clamping member includes a connecting plate, which is mounted on the clamping rod, the connecting plate is located above the bottom support plate, a cylinder telescopic rod is mounted on the connecting plate, the telescopic end of the cylinder telescopic rod faces the bottom support plate, and the upper clamping plate is mounted on the telescopic end of the cylinder telescopic rod.

[0028] like Figure 1 - Figure 5 As shown, a flexible assembly tool for a vehicle door comprises a working base plate 1, a movable groove 2 is provided on the working base plate 1, a clamping assembly and an adsorption assembly are installed in the movable groove 2, two rotating shafts 14 are symmetrically installed at one end of the working base plate 1, a bottom support frame 15 is rotatably connected to the rotating shaft 14, a supporting base plate 16 is installed at the bottom of the two bottom support frames 15, two supporting members for adjusting the angle of the working base plate 1 are installed on the supporting base plate 16, four mounting holes 18 are symmetrically provided on the supporting base plate 16, and the device as a whole is fixed by fixing external bolts in the mounting holes 18; the clamping assembly cooperates with the adsorption assembly to quickly complete the fixing and releasing operations of the vehicle door, thereby improving production efficiency.

[0029] The clamping assembly includes a first screw rod 3, which is arranged in the moving groove 2 along the direction of the moving groove 2. Both ends of the first screw rod 3 are rotatably connected to the inner wall of the moving groove 2. The thread of the first screw rod 3 is a thread symmetrically arranged at both ends with opposite rotation directions. Two driving blocks 17 are symmetrically arranged on the first screw rod 3. The two driving blocks 17 are respectively threadedly connected to the two ends of the first screw rod 3. A clamping rod 4 is installed on the driving block 17. One end of the first screw rod 3 passes through the working base plate 1 and is connected to the output end of the first servo motor 8. The first servo motor 8 is installed on the working base plate 1 through the motor mounting frame 13.

[0030] The clamping assembly also includes a bottom support plate 5, which is mounted on the clamping rod 4. A buffer pad 6 is installed on the bottom support plate 5. The buffer pad 6 on the bottom support plate 5 can adapt to car doors of different shapes and surface roughnesses to ensure that the car doors will not be damaged during the clamping process. An upper clamping member is installed on the clamping rod 4. The upper clamping member includes a connecting plate 7, which is mounted above the bottom support plate 5. A cylinder telescopic rod 9 is installed on the connecting plate 7. The telescopic end of the cylinder telescopic rod 9 is installed with an upper clamping plate 10, which faces the bottom support plate 5. The design of the upper clamping plate 10 makes the clamping part of the clamping assembly also have a certain flexibility, which can adapt to car doors of different sizes and ensure the tightness and stability of the clamping.

[0031] The adsorption assembly includes two electric cylinders 11, the bottoms of the two electric cylinders 11 are both mounted on the working base plate 1, and the tops of the two electric cylinders 11 are jointly mounted with vacuum suction cups 12, which are connected to an external vacuum device through a pipeline when in use;

[0032] During operation, the car door is placed on the working base plate 1 through the external placement mechanism, so that the car door is placed on the vacuum suction cup 12 on the adsorption assembly, so that the vacuum suction cup 12 adsorbs the bottom of the car door for preliminary fixation, and then the first servo motor 8 is started, and the first servo motor 8 drives the first screw rod 3 connected thereto to rotate on the working base plate 1, so that the first screw rod 3 drives the two driving blocks 17 threadedly connected thereto to approach each other, so that the two driving blocks 17 drive the clamping rod 4 to move to both sides of the car door, so that the bottom support plate 5 connected to the clamping rod 4 is located below the car door, and then the electric cylinder 11 drives the vacuum suction cup 12 connected thereto to move downward, so that the car door adsorbed by the vacuum suction cup 12 falls on the buffer pads 6 on the two bottom support plates 5, so that the two clamping rods 4 are clamped on both sides of the car door, and then the cylinder telescopic rod 9 drives the upper clamping plate 10 to move downward, so that the two upper clamping plates 10 are clamped on the upper parts of both sides of the car door, thereby further fixing the car door;

[0033] The vehicle door is initially fixed by the vacuum suction cup 12 of the adsorption assembly. The vacuum suction cup 12 can provide a uniform adsorption force, which is helpful for the initial positioning of the vehicle door. Subsequently, the clamping assembly drives the two driving blocks 17 to approach each other through the first screw 3, thereby driving the clamping rod 4 to clamp on both sides of the vehicle door, and the bottom support plate 5 is supported under the vehicle door. At the same time, the cylinder telescopic rod 9 drives the upper clamping plate 10 to move downward and clamp on the upper parts of both sides of the vehicle door. This double fixing method greatly enhances the stability of the vehicle door. Even if a large force or vibration is encountered during the assembly process, the vehicle door is not easy to fall off.

[0034] like Figure 1-Figure 5 As shown, the support member includes an articulated frame 21, the bottom of which is installed on the supporting base plate 16, a hydraulic telescopic rod 19 is hinged on the articulated frame 21, an articulated frame 1 20 is installed at one end of the hydraulic telescopic rod 19 away from the articulated frame 21, and the top of the articulated frame 1 20 is installed at the bottom of the working base plate 1.

[0035] During operation, the door is fixed by the adsorption component and the clamping component. When assembling the door, if the door needs to be tilted, the hydraulic telescopic rod 19 is pushed upward, and the hinged frame 21 at the bottom and the hinged frame 1 20 at the top of the hydraulic telescopic rod 19 drive the working bottom plate 1 to move upward, so that the working bottom plate 1 rotates on the bottom support frame 15 through the rotating shaft 14 connected to the other end, and then the working bottom plate 1 drives the door fixed thereto to deflect at an angle, which is convenient for the staff to assemble the door;

[0036] The use of suction and clamping components to fix the car door, coupled with the hydraulic system of the support for stable support, can greatly reduce the risk of accidental falling or movement of the car door during assembly. This not only protects the safety of the workers, but also reduces the possibility of damage to the car door.
