Description

Technical Field

[0001] This utility model relates to the field of aircraft box folding technology, and in particular to an aircraft box folding clamp. Background Technology

[0002] For example, Chinese Patent No. CN221366052U discloses a tooling mechanism for quick folding of an airplane box. The unfolded airplane box is placed horizontally into the tooling mechanism along the folding guide wheel under the limitation of the folding guide limiting plate, the stop block and the fixed baffle. When the airplane box is pressed into the fixture, the box body is folded. The airplane box cover completes the entire folding process of the airplane box under the action of the pressure rod.

[0003] The folding fixture for the aircraft box in the aforementioned application only limits the aircraft box from the side. When folding the aircraft box, it is still necessary to manually press the aircraft box and then fold the side of the aircraft box into the inside of the aircraft box to complete the folding. The overall efficiency is low, and workers are prone to fatigue due to long-term repetitive folding operations, which leads to an increase in the error rate of the fixture, excessive force and other reasons that cause the aircraft box to break, resulting in quality problems and indirectly increasing the company's costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a folding fixture for airplane boxes, which solves the technical problems that existing technologies still require manual folding of airplane boxes, resulting in low efficiency and increased error rates, causing damage to airplane boxes and increasing production costs for enterprises. The present invention achieves the goal of automating the folding of airplane boxes, improving folding efficiency, and reducing damage and loss of airplane boxes.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a folding clamp for an airplane box, comprising multiple folding guide columns regularly mounted in a rectangular shape on a base, with rollers rotatably connected to the folding guide columns via rotating shafts. A support frame is mounted on the base, with an electric lifting rod mounted on the top of the support frame, and a pressure plate mounted on the free end of the electric lifting rod passing through the support frame. A lifting mechanism for automatically lifting the folded airplane box is mounted on the base, and an mounting frame is mounted on the left side of the base, with an electric push rod mounted on the mounting frame. A push plate is mounted on the free end of the electric push rod, and a side folding mechanism for inwardly pressing and folding the sides of the airplane box is mounted on the folding guide columns at the front, rear, left, and right corners.

[0006] A further improvement is that the inner side of the top of the guide post is an arc-shaped structure, the roller is rotatably connected to the inside of the rotating groove opened on the guide post, and its outer side protrudes from the side of the guide post.

[0007] A further improvement is that the lifting mechanism includes lifting springs installed on the four sides of the middle part of the base, and a support plate adapted to the pressure plate is installed on the top of the lifting spring, and an electrical contact is installed at the bottom center of the support plate and the top center of the base.

[0008] A further improvement is that the electrical contact is electrically connected to both the electric lifting rod and the electric push rod, and a through hole is provided on the base inside the lifting spring. A limiting rod is installed at the bottom of the support plate inside the lifting spring and slidably connected to the through hole.

[0009] A further improvement is that the side folding mechanism includes a rotating shaft rotatably connected to a rotating hole in the folding guide post and connected at one end to the roller shaft. A torsion spring is installed in a spring cavity in the rotating hole and sleeved on the rotating shaft. An arc-shaped block is installed on the folding guide post and above the rotating shaft. A gear is installed at the other end of the rotating shaft, and a rotating gear is meshed with the gear. A rotating rod is installed on the back of the rotating gear and slidably connected to an arc-shaped groove in the arc-shaped block. A pressure rod is installed on the front of the rotating gear.

[0010] A further improvement is that the rotating rod has a T-shaped structure, and the arc-shaped groove on the arc block is a T-shaped arc-shaped groove that is adapted to the rotating rod.

[0011] By employing the above technical solution, this utility model provides a folding clamp for an airplane box, which has at least the following beneficial effects:

[0012] 1. This utility model uses an electric lifting rod to push the pressure plate down, pressing the aircraft box into the base and pushing the tray to compress the lifting spring down until the two electric contacts make contact and send an electrical signal to stop the electric lifting rod from moving down. This quickly completes the folding of the aircraft box without the need for manual folding, improving production efficiency and reducing damage to the aircraft box caused by manual folding.

[0013] 2. This utility model uses an electric lifting rod to rise and reset. The lifting spring resets under its own elasticity, which drives the tray to lift the folded airplane box. Then, the delayed electric push rod pushes the push plate to the right, thereby pushing the folded airplane box out. No manual unloading is required, which improves production efficiency.

[0014] 3. In this utility model, the roller is pressed down and the airplane box is driven to rotate, which in turn drives the rotating shaft and the gear on it to rotate, which in turn drives the rotating gear to rotate. As the rotating gear rotates, the rotating rod at its rear end slides inward along the groove opened on the arc block. The pressure rod at its front end also rotates and presses and folds the high part of the side of the airplane box into the inside of the airplane box, thereby completing the pressing of the airplane box edge.

[0026] 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.

[0027] Example 1

[0028] Given that current technology still requires manual folding of the aircraft box, which is inefficient and leads to increased error rates, damage, and higher production costs, this embodiment provides an aircraft box folding fixture. Please refer to... Figures 1-5This embodiment provides a folding fixture for airplane boxes, which can automatically fold airplane boxes, improve folding efficiency, and reduce damage and loss. The airplane box folding fixture includes multiple folding guide posts 2 regularly mounted on a base 1 in a rectangular shape. Rollers 3 are rotatably connected to the folding guide posts 2 via rotating shafts. The fixture is characterized by: a support frame 4 mounted on the base 1; an electric lifting rod 5 mounted on the top of the support frame 4; a pressure plate 6 mounted on the free end of the electric lifting rod 5 passing through the support frame 4; a lifting mechanism 7 automatically lifting the folded airplane box on the base 1; a mounting frame 8 mounted on the left side of the base 1; an electric push rod 9 mounted on the mounting frame 8; a push plate 10 mounted on the free end of the electric push rod 9; and side folding mechanisms 11 for inwardly pressing and folding the sides of the airplane box mounted on the four corner folding guide posts 2.

[0029] The inner top of the folding guide post 2 has an arc-shaped structure, and the roller 3 is rotatably connected to the inside of the rotating groove opened on the folding guide post 2, with its outer side protruding from the side of the folding guide post 2.

[0030] The lifting mechanism 7 includes lifting springs 71 installed on the four sides of the middle part of the base 1. A support plate 72 adapted to the pressure plate 6 is installed on the top of the lifting springs 71. Electrical contacts 73 are installed at the bottom center of the support plate 72 and the top center of the base 1. The electrical contacts 73 are electrically connected to the electric lifting rod 5 and the electric push rod 9. When the aircraft box is placed on the base 1, the electric lifting rod 5 is activated to push the pressure plate 6 downward, thereby driving the aircraft box to be pressed into the base 1 along the arc surface structure at the top of the guide post 2 and the roller 3 thereon, and pushing the support plate 72 to press down. The lifting spring 71 moves down until the electrical contact 73 at the bottom of the support plate 72 and the electrical contact 73 on the base 1 make contact and send an electrical signal to the electric lifting rod 5, stopping its downward movement. This quickly completes the folding of the aircraft box. Then, the electric lifting rod 5 rises and resets. The lifting spring 71 resets under its own elasticity, causing the support plate 72 to lift the folded aircraft box. Then, the delayed electric push rod 9 pushes the push plate 10 to the right, thus pushing the folded aircraft box out. No manual folding or unloading is required, which improves production efficiency and reduces the breakage rate of the aircraft box.

[0031] To prevent the lifting spring 71 from warping when the support plate 72 moves downward and compresses it, thus affecting the contact between the two electrical contacts 73, a through hole is provided on the base 1 inside the lifting spring 71. A limiting rod 74 is installed at the bottom of the support plate 72, located inside the lifting spring 71 and slidably connected to the through hole. When the support plate 72 moves downward, it drives the limiting rod 74 at its bottom to move downward along the through hole on the base 1, thereby restricting the lifting spring 71 to be compressed only in the vertical direction of the limiting rod 74, preventing the lifting spring 71 from warping under force and affecting the contact between the two electrical contacts 73.

[0032] Example 2

[0033] Because some aircraft boxes often employ a double-layer structure on their sides to enhance protection, the protruding portion of the box needs to be folded into the folded interior. Therefore, based on Example 1, as... Figures 1-5 As shown, the device is also provided with a side folding mechanism 11. The side folding mechanism 11 includes a rotating shaft 111 rotatably connected to a rotating hole opened on the folding guide post 2 and one end connected to the axis of the roller 3. A torsion spring 112 is installed in a spring cavity opened in the rotating hole and sleeved on the rotating shaft 111. An arc-shaped block 113 is installed on the folding guide post 2 and above the rotating shaft 111. A gear 114 is installed at the other end of the rotating shaft 111, and a rotating gear 115 is meshed on the gear 114. A rotating rod 116 is installed on the back of the rotating gear 115 and slidably connected to an arc-shaped groove opened on the arc-shaped block 113. A pressure rod 117 is installed on the front of the rotating gear 115.

[0034] The rotating rod 116 has a T-shaped structure, and the arc-shaped groove on the arc block 113 is a T-shaped arc-shaped groove that matches the rotating rod 116. As the roller 3 is driven to rotate by the downward-pressed aircraft box, it drives the rotating shaft 111 to rotate, thereby driving the gear 114 to rotate, which in turn drives the rotating gear 115 that meshes with it to rotate. As the rotating gear 115 rotates, it drives the rotating rod 116 at its rear end to slide inward along the groove on the arc block 113. The pressure rod 117 at its front end also rotates, pressing and folding the high part of the side of the aircraft box into the inside of the aircraft box, thereby completing the pressing of the edge of the aircraft box.
