[0021] like Figure 1-5 As shown, this embodiment provides an adjustable assembly platform for a vehicle body shell, comprising a base 1, a workbench 2 arranged on the base 1, and a driving cylinder 3 for driving the workbench 2 to flip, and a clamping assembly 4 for positioning the vehicle body shell is arranged around the workbench 2. A hinge column 11 for hingedly connecting one side of the bottom of the workbench 2 is arranged on one side of the upper end of the base 1, and a support column 12 for supporting the other side of the bottom of the workbench 2 is arranged on the other side of the base 1. The driving cylinder 3 is movably arranged on one side of the support column 12 on the base 1 and supports the workbench 2 upward. A group of movable support devices is arranged on the edge of one side of the hinge column 11 on the base 1, and each group of movable support devices has two and is distributed on the left and right ends of the base 1.

[0022] The movable support device includes a screw lift 5, a servo motor 6, and a movable support assembly 7. The screw lift 5 is a worm gear screw lift 5, which is a prior art. The bottom end of the screw lift 5 is fixedly arranged on the base 1. One side of the screw lift 5 is driven by the servo motor 6 and drives the lifting head to lift. The movable support assembly 7 is arranged on the lifting head of the screw lift 5. The movable support assembly 7 includes an articulated seat 71, an articulated block 72 and a sliding support plate 75. The articulated seat 71 is articulated to the articulated block 72 at the bottom of the sliding support plate 75 through an articulated shaft 73. A limit plate 711 for limiting the rotation angle of the hinge block 72 is provided on the side of the hinge seat 71 close to the driving cylinder 3. An elastic member is provided on the hinge shaft 73 to support the hinge block 72 to one side, so that one side of the hinge block 72 is pressed against the limit plate 711, and the sliding support plate 75 is set at an angle, and a support plate 21 corresponding to the position of the sliding support plate 75 is provided at the bottom of the workbench 2. The height of the movable support assembly 7 is adjusted by the screw lift 5 and the sliding support plate 75 is made to fit with the support plate 21 at the bottom of the workbench 2 after the flipping, so as to play a supporting role.

[0023] In this embodiment, the size of the support plate 21 is larger than that of the sliding support plate 75, so that when the workbench 2 is flipped at different angles, the sliding support plate 75 can completely fit with the support plate 21 and the surface to play a supporting role.

[0024] In this embodiment, the surfaces of the support plate 21 and the sliding support plate 75 are both smooth surfaces, and a smooth plane with low friction is adopted, so that the sliding support plate 75 can rotate smoothly under the pressure of the support plate 21.

[0025] In another embodiment, a plurality of grooves are provided on the surface of the sliding support plate 75, and a roller 76 is provided in each groove, so that the sliding support plate 75 is rollingly connected to the surface of the support plate 21 through the roller 76. The rolling connection reduces friction resistance, so that the support plate 21 can more easily drive the sliding support plate 75 to move to adapt to its support angle.

[0026] In this embodiment, a recess for accommodating an elastic member is provided at the bottom of the hinge block 72, and the elastic member is a torsion spring 74. The torsion spring 74 is sleeved on the hinge shaft 73 and supports the hinge block 72 and abuts against the limit plate 711 to maintain the minimum angle of the sliding support plate 75 and enable it to contact the inclined support plate 21. When the flipping angle of the workbench 2 is larger, the rotation angle of the slide support plate is also larger.

[0027] In this embodiment, a pressure sensor for detecting the pressure may be further provided between the support plate 21 and the bottom of the workbench 2. When the pressure sensor detects that the pressure reaches a specified value, the controller may control the servo motor 6 to stop driving the screw lift 5 to rise.

[0028] The working principle of the utility model is as follows: when the workbench 2 is flipped to a certain angle and stops under the drive of the driving cylinder 3, the movable support device is started, and the servo motor 6 drives the screw lift 5 to drive the movable support assembly 7 to rise, and then the sliding support plate 75 is pressed against the support plate 21, and at the same time, the sliding support plate 75 rotates under the action of pressure, and the surface of the sliding support plate 75 is completely in contact with the surface of the support plate 21 and supports it, and then when the pressure sensor detects that the pressure reaches the specified value, the controller controls the servo motor 6 to stop, and finally the movable support device completes the support of the workbench 2.

[0029] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
