[0028] Reference Figure 1-4This utility model discloses a prefabricated cabin door panel straightening fixture, which includes a base 1. Two hydraulic cylinders 9 are symmetrically fixedly installed in the middle of the base 1. A support platform 19 is fixedly installed at the extension end of the two hydraulic cylinders 9. A slot 23 is opened on the left side of the support platform 19. A motor 20 is fixedly installed on one side of the support platform 19. The output end of the motor 20 passes through the support platform 19 and is fixedly connected to a positive and negative lead screw 22. The end of the positive and negative lead screw 22 away from the motor 20 is rotatably installed in the slot 23. A slot 24 is opened on the right side of the support platform 19. A slide rod 25 is fixedly installed inside the slot 24. Two clamping plates 21 are symmetrically installed on the positive and negative screw rods 22. The other end of the clamping plates 21 is slidably installed on the slide rod 25. In use, the level of the support platform 19 can be adjusted by starting the hydraulic cylinder 9 according to the deformation of the door panel. Then, according to the size of the door panel, the motor 20 is started, which drives the positive and negative screw rods 22 fixedly connected to the output end of the motor 20 to rotate. At the same time, it drives the clamping plates 21 installed on the positive and negative screw rods 22 and slidably installed on the slide rod 25 to move relative to each other, thereby clamping the door panel.

[0029] A fixing block 10 is fixedly installed on one end of the base 1. A groove 15 is provided on the upper end of the fixing block 10. A motor 16 is fixedly installed on one side of the fixing block 10. The output end of the motor 16 passes through the fixing block 10 and is fixedly connected to a lead screw 17. The end of the lead screw 17 away from the motor 16 is rotatably installed in the groove 15. Two limit posts 18 are fixedly installed in the groove 15. The two limit posts 18 are located on both sides of the lead screw 17. A movable block 11 is installed on the lead screw 17. The movable block 11 is slidably installed on the limit posts 18. In use, by starting the motor 16, the lead screw 17 fixedly connected to the output end of the motor 16 is driven to rotate, thereby driving the movable block 11 installed on the lead screw 17 and slidably installed on the limit posts 18 to perform reciprocating linear motion.

[0030] A through slot 13 is provided on the movable block 11. Two sliding columns 12 are fixedly installed in the through slot 13. A cylinder 26 is fixedly installed on one side of the movable block 11. A sliding block 14 is fixedly installed through the extended end of the cylinder 26. The sliding block 14 is slidably installed on the sliding column 12. A hydraulic cylinder 27 is fixedly installed at the bottom of the sliding block 14. A pressure head 28 is fixedly installed at the extended end of the hydraulic cylinder 27. In use, by starting the cylinder 26, the sliding block 14 fixedly installed at the extended end of the cylinder 26 is driven to move. When it reaches the designated position, the hydraulic cylinder 27 is started again, which drives the pressure head 28 fixedly installed at the extended end of the hydraulic cylinder 27 to move downward, thereby straightening the door panel. The pressure head 28 is selected to be compatible with the door panel.

[0031] Four support legs 1 2 are fixedly installed at the bottom of the base 1. Each support leg 1 2 has a through hole. Support legs 2 3 are slidably installed on support legs 1 2. A support plate 5 is fixedly installed on one side of support legs 2 3. A pin 8 is inserted through one side of the support plate 5. A pull rod 4 is fixedly installed at one end of the pin 8. An arc-shaped block 7 is fixedly installed in the middle of the pin 8. The arc-shaped block 7 is adapted to support legs 2 3. A spring 6 is fixedly installed on one side of the arc-shaped block 7. The other end of the spring 6 is fixedly installed on the support plate 5. The spring 6 is sleeved on the pin 8. First, pull the pull rod 4 outward to disengage the pin 8 from the through hole on support legs 1 2. Then, slide support legs 1 2 to adjust to a suitable height within support legs 2 3. Finally, release the pull rod 4. Due to the rebound force of the spring 6, the pin 8 is inserted back into the through hole on support legs 1 2 for fixation.

[0032] Working principle: When using a prefabricated cabin door panel straightening fixture, first adjust the base 1 to a suitable height. Then, pull the lever 4 outwards to disengage the pin 8 from the through hole in the support leg 2. The support leg 2 slides within the support leg 3 to adjust to a suitable height. Finally, release the lever 4. The pin 8, under the restoring force of the spring 6, re-inserts into the through hole in the support leg 2 for fixation. Then, depending on the size of the door panel, start the motor 20 to rotate the positive and negative lead screws 22, causing relative movement between the clamping plate 21, which is fitted onto the positive and negative lead screws 22 and slidably mounted on the slide rod 25. This clamps the door panel. Then, based on the deformation of the door panel, hydraulic cylinder 9 is activated to adjust the level of the support platform 19. Finally, based on the position of the door panel deformation, motor 16 is activated to drive the fixed lead screw 17 to rotate, thereby driving the movable block 11, which is mounted on the lead screw 17 and slidably mounted on the limit post 18, to move. When the movable block 11 is opposite to the door panel deformation, cylinder 26 is activated to drive the sliding block 14 to move. When it reaches above the deformation position of the door panel, hydraulic cylinder 27 is activated to drive the pressure head 28 to move downward, thereby straightening the door panel.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
