Description

Technical Field

[0001] The utility model belongs to the field of sheet metal forming and skin turnover, and specifically relates to a large-scale flat plate material turnover hoisting device. Background Art

[0002] With the rapid development of large military and civilian aircraft in my country in recent years, the size of skin production has become increasingly larger, and product quality requirements have also continued to increase. As the appearance and conformal components of an aircraft, skin parts have extremely stringent requirements for surface quality and appearance. The commonly used forming methods for skin forming are stretch forming and roll forming. The skin raw material (hereinafter referred to as skin raw material) is transported from a flat sheet to the machine tool worktable during the turnover process. Currently, this method is basically carried by hand or with a sling. This method has the following main disadvantages:

[0003] The turnover efficiency is poor when manual handling is used. First, it is difficult to control the uniform standing position of the person, and the direction and strength of the force exerted by the person carrying the goods are uncontrollable. In addition, the turnover process is not a simple translation process, so the skin raw material is easily subjected to uneven force during the handling process, resulting in bulging of the skin, which may be difficult to eliminate in the subsequent stretching or rolling forming process.

[0004] When using a lifting rope for transportation, the skin material has no fixing device, which increases the risk of it falling during transportation and poses a major safety hazard. During unloading, the direction of unloading of the skin material is difficult to control, and the skin material and mold are easily damaged when the lifting rope is pulled out. Utility Model Content

[0005] In view of the above-mentioned existing technology, the purpose of this utility model is to overcome the shortcomings of the existing technology and adapt to actual needs, thereby providing a large-scale flat material turnover and lifting device that can solve the problems of poor turnover efficiency of skin raw materials to machine tool worktables and damage to the skin.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a large flat material turnover lifting device, including a clamping device and a lifting device, the clamping device is provided with two groups, the two groups of clamping devices are respectively clamped on the two long sides of the skin raw material, and there are four lifting devices, each group of clamping devices is connected to a lifting device at both ends of the left and right sides, wherein each group of clamping devices includes a support frame, two positioning blocks and two clamping bolts, the two support frames are both L-shaped long plates, the rear ends of the two positioning blocks located in the same group of clamping devices are respectively fixed on the left and right ends of the vertical surface of the support frame, and a gap is left between the horizontal surface of the support frame to accommodate the skin raw material, a bolt through hole is provided in the middle of the upper end of the four positioning blocks for the clamping bolt to pass through, and the four clamping bolts respectively pass through the bolt through holes on the four positioning blocks to fix the skin raw material to the two support frames, the horizontal surfaces of the two support frames are both in contact with the bottom of the skin raw material, and two lifting holes are also provided on the vertical surface of each support frame, and the four lifting devices are respectively installed on the four lifting holes.

[0007] Furthermore, it also includes a reinforcement device, which includes a connecting rod and four support rods. The left and right ends of the connecting rod are respectively connected to one end of the two support rods by fastening bolts, the other ends of the two support rods located at the left end of the connecting rod are respectively connected to the left end of the positioning block located on the left end of the vertical surface of the support frame by fastening bolts, and the other ends of the two support rods located at the right end of the connecting rod are respectively connected to the right end of the positioning block located on the right end of the vertical surface of the support frame by fastening bolts.

[0008] Furthermore, the rear ends of the positioning blocks are welded to the vertical surfaces of the support frames.

[0009] Furthermore, the positioning blocks are detachably connected to the support frame.

[0010] Furthermore, the positioning blocks are fixedly connected to the support frame by bolts.

[0011] Furthermore, the outer end faces of the four positioning blocks are flush with the left and right end faces of the vertical surface of the support frame respectively, the upper end faces are flush with the top of the vertical surface of the support frame, and the positioning blocks are parallel to the horizontal surface of the support frame.

[0012] Furthermore, the two positioning blocks and the support frame in the same set of clamping devices are an integrally formed structure.

[0013] Furthermore, the lifting device is a lifting ring, which is installed on the lifting hole on the support frame.

[0014] Furthermore, the two lifting rings on the same set of clamping devices are both located between the two positioning blocks.

[0015] Furthermore, rubber is provided on the contact surfaces of the support frame and the clamping bolts with the skin material.

[0016] In the present invention, the skin is large in size, relatively small in thickness, and poor in rigidity. Based on this characteristic of the skin, a lifting device is designed. The lifting device consists of a support frame, a positioning block, a clamping bolt, a lifting ring, a support rod, a connecting rod, and a fastening bolt, wherein the support frame, the positioning block, and the clamping bolt are mainly used to clamp the skin raw material, the support rod is connected to the positioning block through a fastening bolt, and the four support rods are connected through a connecting rod, and the lifting ring is installed on the support frame. Use the support frame to fix the support frame and the positioning block (two on the left and right), drill bolt holes on the positioning block and insert the clamping bolts, open lifting holes at appropriate positions on the support frame and install lifting rings (two on the left and right), connect the support rod to the positioning block through a fastening bolt, and connect the four support rods together through a connecting rod, so as to ensure the rigidity and stability of the lifting device. During the skin lifting process, the skin raw material is fixed with clamping bolts. The skin raw material is acted on the lifting ring through the crane. During the lifting process, it will naturally move downward due to its own gravity. The skin is subjected to relatively uniform force throughout the whole process and the rigidity of the skin raw material is relatively increased, thereby effectively solving the problems caused by the original transportation method.

[0017] The beneficial effects of the utility model are:

[0018] 1. Improve turnover efficiency: The hoisting device does not require too many operators, and the process of fixing and separating the skin material and the hoisting device is simple to operate, which can greatly increase turnover efficiency.

[0019] 2. Avoid damage to the skin material during its rotation: Using the previous solution, the skin material was prone to surface scratches, bulging, and other adverse effects during its rotation. This lifting device increases the relative rigidity of the skin, ensures uniform force during the lifting process, and reduces contact between the operator and the skin material, essentially avoiding such damage.
