Description

Technical Field

[0001] This utility model relates to the field of aerospace equipment, and in particular to an adsorption and positioning device for aerospace equipment plates. Background Technology

[0002] An existing patent (publication number: CN221936036U) proposes an adsorption-type positioning device for aerospace equipment processing, comprising a support plate, a first baffle plate, and a second baffle plate. Several adsorption holes are formed on the upper surface of the support plate. Side wall baffles are provided at the front and rear ends of the lower surface of the support plate. The first and second baffle plates are slidably arranged between the two side wall baffles. The first side wall plate is fixedly installed at the left end of the lower surface of the support plate, and the second side wall plate is fixedly installed at the right end. A first lead screw and a second lead screw, which cooperate with the first and second baffle plates, are provided between the first and second side wall plates. A base plate is provided below the support plate. However, this device only adsorbs and fixes the bottom of the plate through the "support plate," while lacking a pressing and fixing structure on the upper part of the plate. When the plate surface is uneven, gaps easily form between the plate and the adsorption surface, leading to negative pressure leakage and weakened adsorption force. As a result, when the plate is subjected to external force during processing, it is prone to local arching or vibration, resulting in unsatisfactory positioning and having drawbacks. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing an aerospace equipment plate adsorption and positioning device that achieves balanced force on the upper and lower parts of the plate through coordinated control of adsorption and compression. This avoids negative pressure leakage caused by unevenness of the plate surface, enhances the positioning stability of the plate, and allows for flexible adjustment of the adsorption area of ​​the suction cup according to the actual width of the plate. It is highly versatile, widely applicable, and easy to operate, thereby improving the adsorption and positioning efficiency of aerospace equipment plates.

[0004] The objective of this utility model is achieved through the following technical solution: A device for adsorbing and positioning aerospace equipment sheet metal includes a fixed base, a suction cup, a partition, a positioning support rod, a connecting rod, a bearing plate, and a pressure plate. The fixed base has a suction pipe on one side, connected to an air pump via a pipe, and an exhaust pipe on the other side, equipped with a control valve. The fixed base has an internal slide rail that adapts to the partition, which is connected to the slide rail and slides within it. Positioning supports are located on both sides of the partition. The fixed base has an external mounting support with a placement groove that adapts to a rotating sleeve and is connected to it. A worm gear is located on the outside of the rotating sleeve. The positioning support rod is connected internally to the rotating sleeve via screws. The screws sequentially connect the rotating sleeve and the positioning support rod, which sequentially passes through the mounting support, rotating sleeve, fixed base, and positioning support. The positioning support rod is threadedly connected to the positioning support sleeve.

[0005] The lower part of the mounting bracket of this utility model is connected to the baffle. The mounting bracket is connected to the outside of the bearing. The inside of the bearing is connected to the drive rod. The outer end of the drive rod has a rotating wheel. The rotating wheel fits into the mounting bracket. The inner end of the drive rod is connected to the connecting rod. Both ends of the connecting rod have worms. The worms are adapted to worm wheels. The worm wheels are connected to the worms.

[0006] The fixed base of this utility model is connected to a suction cup, which has multiple suction holes. A cylinder is connected to the upper part of the support plate. The cylinder is equipped with a piston rod that passes through the support plate. The piston rod is connected to a pressure plate, and the pressure plate is connected to a rubber pad. Beneficial effects

[0007] This utility model's suction cup creates a uniform negative pressure on the bottom of aerospace equipment sheet material through its suction holes. Simultaneously, a cylinder on the support plate drives the pressure plate downwards, which, together with the rubber pad, flexibly presses the upper part of the sheet material, ensuring balanced force on the upper and lower parts of the sheet material. Even if there are local unevenness in the sheet material, the pressure of the pressure plate can eliminate the gap between the sheet material and the suction cup, preventing negative pressure leakage, improving the positioning stability of the sheet material, and ensuring that there is no local arching or vibration of the sheet material during processing. Furthermore, the rubber pad at the bottom of the pressure plate has a certain degree of elasticity, which not only enhances the pressing effect but also avoids hard damage to the surface of the sheet material, increasing its protection.

[0008] This invention uses a rotating wheel to drive a drive rod to rotate, which in turn drives the worm gear and worm to move together. By using forward and reverse thread transmission, the two side partitions slide synchronously towards or away from each other in the slide, allowing the suction cup adsorption area to be flexibly adjusted according to the actual width of the material. This ensures concentrated adsorption force for small-sized materials while also meeting the comprehensive adsorption needs of large-sized materials. It is highly versatile and has a wide range of applications. The sliding adjustment of the partition and the lifting control of the pressure plate of this utility model are independent of each other but can work together. The operator can first adjust the position of the partition by the rotating wheel to determine the adsorption range, and then start the cylinder to make the pressure plate complete the upper pressing. The operation process is simple, stable and reliable, reduces the difficulty of operation and improves the adsorption and positioning efficiency of aerospace equipment plates. This utility model device achieves balanced force on the upper and lower parts of the plate through the coordinated control of adsorption and compression, avoiding negative pressure leakage caused by uneven plate surface, enhancing the positioning stability of the plate, and allowing flexible adjustment of the adsorption area of ​​the suction cup according to the actual width of the plate. It is highly versatile, widely applicable, and easy to operate, improving the adsorption and positioning efficiency of aerospace equipment plates. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A device for adsorbing and positioning aerospace equipment sheet metal includes a fixed base 01, a suction cup 02, a partition 07, a positioning support rod 09, a connecting rod 14, a bearing plate 23, and a pressure plate 24. The fixed base 01 has a suction pipe 04 on one side, which is connected to an air pump via a pipe. The fixed base 01 also has an exhaust pipe 05 on the other side, equipped with a control valve 06. The fixed base 01 has a slide rail 28 inside, which is adapted to the partition 07. The partition 07 is connected to the slide rail 28 and slides within it. Positioning supports 08 are located on both sides of the partition 07. The fixed base 01 also has an external mounting support 17, which has a placement groove 18 adapted to a rotating sleeve 12. The placement slot 18 is connected to the rotating sleeve 12. The rotating sleeve 12 has a worm gear 10 on its outside. The rotating sleeve 12 is connected to the control support rod 09 through the screw 13 inside. The screw 13 is connected to the rotating sleeve 12 and the control support rod 09 in sequence. The control support rod 09 passes through the mounting support 17, the rotating sleeve 12, the fixed seat 01, and the control support 08 in sequence. The control support rod 09 is connected to the control support 08 through the thread. The sliding adjustment of the partition 07 and the lifting control of the pressure plate 24 are independent of each other but can work together. The operator can first adjust the position of the partition 07 through the rotating wheel 27 to determine the adsorption range, and then start the cylinder 20 to make the pressure plate 24 complete the upper clamping. The operation process is simple, stable and reliable, reduces the difficulty of operation, and improves the adsorption and positioning efficiency of aerospace equipment plates. Example 2: The mounting sleeve 17 of this utility model is connected to a baffle 19 at its lower part. The mounting sleeve 17 is connected to the outside of the bearing 16. The bearing 16 is connected to a drive rod 15. The outer end of the drive rod 15 has a rotating wheel 27, which fits against the mounting sleeve 17. The inner end of the drive rod 15 is connected to a connecting rod 14. The connecting rod 14 has worm gears 11 at both ends. The worm gears 11 are adapted to the worm wheel 10. The worm wheel 10 is connected to the worm gears 11. By rotating the rotating wheel 27, the drive rod 15 is driven to rotate, which drives the worm wheel 10 and the worm gears 11 to cooperate and move together. By using the forward and reverse thread transmission, the partition plates 07 on both sides slide synchronously towards or away from each other in the slide 28. This allows for flexible adjustment of the adsorption area of ​​the suction cup 02 according to the actual width of the board. This ensures that the adsorption force of small-sized boards is concentrated, while also meeting the comprehensive adsorption needs of large-sized boards. It has strong versatility and a wide range of applications. Example 3: The fixed base 01 of this utility model is connected to a suction cup 02, which has multiple suction holes 03.

The cylinder 20 is equipped with a piston rod 21, which passes through the support plate 23 and is connected to a pressure plate 24. The pressure plate 24 is connected to a rubber pad 25. The suction cup 02 forms a uniform negative pressure on the bottom of the aerospace equipment plate through the suction holes 03. At the same time, the cylinder 20 on the support plate 23 drives the pressure plate 24 to move down, which, together with the rubber pad 25, flexibly presses the upper part of the plate, so that the plate is balanced by the force on the upper and lower parts. Even if there is local unevenness in the plate, the pressure of the pressure plate 24 can eliminate the gap between the plate and the suction cup 02, avoid negative pressure leakage, improve the positioning stability of the plate, and ensure that there is no local arching or vibration of the plate during processing. In addition, the rubber pad 25 at the bottom of the pressure plate 24 has a certain elasticity, which can enhance the pressing effect and avoid hard damage to the surface of the plate, thus increasing the protection of the plate.

[0017] Example 4: The present invention has fixed support rods 22 on both sides of the bearing plate 23 and side through holes 26 on both sides of the pressure plate 24. The fixed support rods 22 are adapted to the side through holes 26 and pass through the side through holes 26. The fixed support rods 22 are connected to the upper part of the suction cup 02 and the lower part of the suction cup 02 is attached to the partition plate 07. This device achieves balanced force on the upper and lower parts of the plate through the coordinated control of adsorption and pressing, avoiding negative pressure leakage caused by unevenness of the plate surface. It enhances the positioning stability of the plate and allows for flexible adjustment of the adsorption area of ​​the suction cup 02 according to the actual width of the plate. It is highly versatile, has a wide range of applications, and is easy to operate, thus improving the adsorption and positioning efficiency of aerospace equipment plates.

[0018] Example 5: Installation steps: First, assemble the control structure of partition 07. Place partition 07 into slide 28, then place rotating sleeve 12 into placement groove 18.

Then, place connecting rod 14 and rotating wheel 27 on the inner and outer sides of mounting sleeve 17, respectively, and embed drive rod 15 into bearing 16 and fix it to connecting rod 14. The two sides are spiral... The rod 11 and the worm gear 10 are positioned and connected. Finally, the baffle 19 is installed and fixed to the lower part of the mounting bracket 17. After the assembly of the partition 07 control structure is completed, the suction cup 02 is installed and fixed to the upper part of the fixing seat 01, and the lower surface of the suction cup 02 is in contact with the partition 07. Then, the cylinder 20 is installed and fixed to the upper part of the bearing plate 23, and the piston rod 21 passes through the bearing plate 23.
