Description

Technical Field

[0001] This utility model relates to the field of sheet metal bracket processing technology, and in particular to a tensioning device for pre-embedded sheet metal brackets in door covers. Background Technology

[0002] Door hood embedded sheet metal brackets are metal components manufactured using sheet metal processes. They are mainly used for fixing, supporting, and reinforcing automotive door hoods. They are commonly made of metals such as steel, stainless steel, and aluminum, balancing strength and lightweight requirements. In automotive repair, they play an important role in ensuring vehicle performance and safety by reinforcing deformed parts and working with stretching devices to restore the vehicle body's precision.

[0003] In existing technologies, when a car door cover is deformed and dented due to an impact, causing the bracket to deform as well, the operator usually uses a suction cup to pull the door cover back, so that the bracket and the door cover are repaired together. However, during the stretching repair, it is necessary to pull back manually, which is quite strenuous. Prolonged operation can easily increase the operator's fatigue and reduce the operator's work efficiency, making it difficult to repair the car door cover and bracket, and the repair efficiency is low. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a door cover pre-embedded sheet metal bracket tensioning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a door cover pre-embedded sheet metal bracket tensioning device, comprising two support frames, a support plate fixedly connected to the lower surface of the support frames, a handle fixedly connected to one side of the two support frames, and a tensioning component provided between the two support frames.

[0006] The tensioning assembly includes a fixed frame, which is fixedly connected between two support frames. A first stepper motor is fixedly installed on the inner wall of the fixed frame. A first lead screw is fixedly connected to the output end of the first stepper motor. A connecting block is threaded onto the external surface of the first lead screw. A mounting frame is fixedly connected to the lower surface of the connecting block.

[0007] As a further description of the above technical solution:

[0008] The connecting block is slidably connected inside the fixed frame, and a second stepper motor is fixedly installed on the inner wall of the mounting frame. The output end of the second stepper motor is fixedly connected to a second lead screw.

[0009] As a further description of the above technical solution:

[0010] The second lead screw is externally threaded with a mounting block, which is slidably connected inside the mounting frame. A hydraulic cylinder is fixedly mounted on one side of the mounting block, and a mounting bracket is fixedly connected to the output end of the hydraulic cylinder.

[0011] As a further description of the above technical solution:

[0012] A cylinder is fixedly mounted on one side of the mounting bracket, and a fixing sleeve is fixedly connected inside the mounting bracket.

[0013] As a further description of the above technical solution:

[0014] A piston plate is fixedly connected to the output end of the cylinder, and the piston plate is slidably connected inside the fixed sleeve. A suction cup is fixedly connected to the lower surface of the fixed sleeve.

[0015] As a further description of the above technical solution:

[0016] The upper surfaces of the two support frames are provided with clamping components, each clamping component including a connecting frame. The connecting frame is fixedly connected to the upper surfaces of the two support frames. A stepper motor is fixedly installed inside the connecting frame, and a bidirectional screw is fixedly connected to the output end of the stepper motor.

[0017] As a further description of the above technical solution:

[0018] The bidirectional screw is externally threaded with two moving blocks, which are slidably connected inside the connecting frame. A connecting frame is fixedly connected to one side of each moving block, and a clamping frame is fixedly connected to one end of each connecting frame.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, through the setting of the stretching component, utilizes the upward movement of the piston plate to facilitate the suction of air inside the suction cup, making it easier for the suction cup to adhere firmly to the car door cover. Then, the upward movement of the hydraulic cylinder makes it easier to replace the manual pulling of the suction cup by the operator, which is more labor-saving. Furthermore, the longitudinal movement position of the mounting block and the lateral movement position of the connecting block make it easy to adjust the position of the suction cup according to the stretching position that needs to be repaired on the car door cover and bracket plate, thus improving the efficiency of stretching repair.

[0021] 2. By setting up a clamping component, this utility model utilizes clamping frames on both sides to facilitate the disassembly of the car door cover and bracket plate into independent units, which are then fixed and clamped between the two clamping frames. This ensures that the car door cover and bracket plate can be stably placed during stretching and repair, reducing the phenomenon of weak stretching effect caused by displacement of the car door cover and bracket plate.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] As attached Figure 1-6 As shown, one embodiment of this utility model is provided: a door cover pre-embedded sheet metal bracket tensioning device, including two support frames 1, a support plate 2 fixedly connected to the lower surface of the support frame 1, a handle 3 fixedly connected to one side of the two support frames 1 for easy hand gripping, and a tensioning component provided between the two support frames 1.

[0032] The tensioning assembly includes a fixed frame 4, which is fixedly connected between two support frames 1. A first stepper motor 5 is fixedly installed on the inner wall of the fixed frame 4. A first lead screw 6 is fixedly connected to the output end of the first stepper motor 5. A connecting block 7 is threadedly connected to the external of the first lead screw 6 to facilitate the lateral movement of the connecting block 7. A mounting frame 8 is fixedly connected to the lower surface of the connecting block 7 for mounting a second lead screw 10.

[0033] As attached Figure 4As shown, the connecting block 7 is slidably connected inside the fixed frame 4. The inner wall of the mounting frame 8 is fixedly mounted with a second stepper motor 9. The output end of the second stepper motor 9 is fixedly connected with a second lead screw 10. The external thread of the second lead screw 10 is connected to a mounting block 11, which facilitates the longitudinal movement of the mounting block 11 by driving the second lead screw 10. The mounting block 11 is slidably connected inside the mounting frame 8. The mounting frame 8 limits the mounting block 11. A hydraulic cylinder 12 is fixedly mounted on one side of the mounting block 11. The output end of the hydraulic cylinder 12 is fixedly connected to a mounting bracket 13 for indirectly connecting the suction cup 17. A cylinder 14 is fixedly mounted on one side of the mounting bracket 13. A fixed sleeve 15 is fixedly connected inside the mounting bracket 13 to provide movement space for the piston plate 16.

[0034] As attached Figure 5 As shown, a piston plate 16 is fixedly connected to the output end of the cylinder 14. The piston plate 16 is slidably connected inside the fixed sleeve 15 to facilitate the suction of air from inside the suction cup 17. The suction cup 17 is fixedly connected to the lower surface of the fixed sleeve 15 for adsorbing onto the recess of the door frame bracket.

[0035] As attached Figure 3 As shown, clamping components are provided on the upper surfaces of the two support frames 1. The clamping components include a connecting frame 19, which is fixedly connected to the upper surfaces of the two support frames 1. A stepper motor 18 is fixedly installed inside the connecting frame 19. A bidirectional screw 20 is fixedly connected to the output end of the stepper motor 18. The bidirectional screw 20 has threads in opposite directions on the outside.

[0036] As attached Figure 1 As shown, the bidirectional screw 20 has two moving blocks 21 connected to its external thread, which are used to drive the connecting frame 22 to move. The two moving blocks 21 are slidably connected inside the connecting frame 19. The connecting frame 19 limits the moving blocks 21. The connecting frame 22 is fixedly connected to one side of the moving block 21. The clamping frame 23 is fixedly connected to one end of the connecting frame 22, which facilitates the repair and stretching of the door frame bracket to be repaired.

[0037] Working principle: When in use, first place the door frame bracket to be pulled between the two clamping frames 23, and then use the external controller to start the stepper motor 18 to turn on, so that the output end of the stepper motor 18 drives the bidirectional screw 20 to rotate. When the bidirectional screw 20 rotates, it will drive the moving blocks 21 on both sides to move closer to each other, thereby driving the clamping frames 23 on both sides to move closer to each other through the connection of the connecting frame 22. The clamping frames 23 clamp the door frame bracket to fix it.

[0038] When adjusting the position of suction cup 17 according to the recessed area of ​​the door frame bracket, first use the controller to turn on the first stepper motor 5, so that its output end drives the first lead screw 6 to rotate, which in turn drives the connecting block 7 to slide inside the fixed frame 4. This allows the connecting block 7 to indirectly drive the suction cup 17 to move laterally through the mounting frame 8. After it has moved to the appropriate position, turn off the first stepper motor 5, and then turn on the second stepper motor 9, so that its output end drives the second lead screw 10 to rotate. This allows the second lead screw 10 to drive the mounting block 11 to slide longitudinally inside the mounting frame 8, which in turn indirectly drives the suction cup 17 to move. The longitudinal displacement is moved to above the position where the rope needs to be pulled, and the second stepper motor 9 can be turned off. Then, when the output end of the hydraulic cylinder 12 pushes the mounting bracket 13 and the fixing sleeve 15 to move down, the suction cup 17 is pressed tightly against the recessed area. Then, the cylinder 14 is activated, and when the output end of the cylinder 14 drives the piston plate 16 to slide inside the fixing sleeve 15, the air inside the suction cup 17 is sucked into the fixing sleeve 15, so that the suction cup 17 can be pressed tightly against the recessed surface. Then, the upward movement and retraction of the output end of the hydraulic cylinder 12 facilitates the indirect upward movement of the suction cup 17, pulling the recessed area upward and stretching it to repair it.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
