Description

Technical Field

[0001] This utility model relates to the field of aircraft parts processing and clamping technology, specifically to a clamping structure and clamping platform for aircraft parts processing. Background Technology

[0002] Aircraft are machines that fly within or outside the atmosphere (space). During manufacturing, each part needs to be processed individually to reduce errors during manufacturing and assembly. Clamping platforms for processing aircraft parts are used during individual processing.

[0003] Existing clamping platforms for aircraft parts processing consist of a worktable and a clamping section. During operation, the aircraft parts to be processed are placed on the worktable, and then mechanically clamped and fixed at the four corners of the aircraft parts to be processed to facilitate subsequent processing operations. However, due to the diverse shapes of the edges of aircraft parts, clamping at the corners can result in the inability to clamp irregularly shaped aircraft parts. Therefore, it is necessary to design a clamping platform for aircraft parts processing that can clamp various edge shapes. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping structure and clamping platform for processing aircraft parts, so as to solve the problem mentioned in the background art that due to the diverse shapes of the edges of aircraft parts, the clamping of irregularly shaped aircraft parts will not be able to be clamped.

[0005] To achieve the above objectives, this utility model provides the following technical solution: On one hand, this utility model provides a clamping structure for machining aircraft parts. This clamping structure is mounted on a clamping platform and includes a placement plate and a clamping structure. The placement plate is detachably fixed to the clamping platform and has an internal groove. A servo motor is detachably installed inside the internal groove. Part of the clamping structure is inserted into the clamping platform. The clamping structure includes a base plate detachably fixed inside the clamping platform and a partition plate fixed to the top of the base plate. The partition plate has a circular hollow cross-section. The partition has an internal drive gear that rotates around its own center. The top of the drive gear is rotatably connected to a detachable top plate. The bottom of the drive gear is detachably connected to the output end of a servo motor. The bottom periphery of the top plate is detachably fixedly connected to the top periphery of the partition. The outer side of the partition has multiple arc-shaped grooves, and a circular groove is formed between adjacent arc-shaped grooves. The circular grooves and arc-shaped grooves are connected. The height of the drive gear is twice the height of the circular groove. A retractable structure is inserted into the arc-shaped groove. The servo motor drives the drive gear to rotate, which in turn drives the retractable structure to open and close.

[0006] Preferably, the shrinking structure includes a threaded column connected in a circular groove, and a secondary moving gear is threaded onto the surface of the threaded column. The secondary moving gear meshes with the driving gear, and the secondary moving gear moves longitudinally relative to the clamping table on the surface of the threaded column.

[0007] Preferably, the bottom of the secondary gear is detachably fixed with a suction cup wall, which is arc-shaped and threaded onto a threaded post. Both the suction cup wall and the top of the top plate are bolted with electric suction cups. The servo motor drives the main gear to rotate, thereby causing the secondary gear to rotate and opening and closing the suction cup wall.

[0008] Preferably, the built-in slot includes a first slot and a second slot. The first slot is located above the second slot. Both the first and second slots have circular cross-sections. The diameter of the first slot is larger than the diameter of the second slot. The second slot is used to install a servo motor. The diameter of the first slot is larger than the diameter of the base plate, and the diameter of the second slot is smaller than the diameter of the base plate.

[0009] Preferably, there are four suction cup walls, and the four suction cup walls can be spliced ​​together to form a complete circle. The diameter of the complete circle is larger than the diameter of the bottom plate, and the diameter of the complete circle is smaller than the diameter of the top plate. The diameter of the top plate is smaller than the diameter of the bottom plate.

[0010] Another aspect of this utility model provides a clamping structure and clamping platform for processing aircraft parts, including a clamping table and a clamping structure for processing aircraft parts as described in any one of the above. The clamping platform includes a baffle, which is detachably mounted on the surface of the clamping table on one side of the placement plate.

[0011] Preferably, the clamping platform also has an air hole, which is disposed in the shelf and is connected to the built-in groove. A rectangular groove is formed in the interior of the shelf away from the air hole, which is connected to the air hole and the built-in groove and penetrates the side wall of the shelf.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this clamping platform for processing aircraft parts not only expands the clamping range of the entire clamping structure by setting a retractable structure, an electric suction cup, a top plate, and a drive gear, where the drive gear drives the retractable structure to rotate under the action of a servo motor; at the same time, the setting of the electric suction cup allows the clamping structure to be used without considering the edge shape of the aircraft parts; through the threaded column and the secondary drive gear, when in use, the secondary drive gear will move longitudinally on the threaded column to adapt to different aircraft parts for clamping.

[0021] 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.

[0022] Example 1: As Figure 1-5 As shown, this embodiment provides a clamping structure and clamping platform for machining aircraft parts. The clamping structure is mounted on a clamping table 1 and includes a placement plate 12 and a clamping structure 2. The placement plate 12 is detachably fixed to the clamping table 1, wherein the four side lengths of the placement plate 12 are all smaller than the four side lengths of the clamping table 1. See details... Figure 1, which is used to place the aircraft parts to be processed. There is an internal groove 13 on the storage plate 12. The longitudinal section of the internal groove 13 relative to the storage plate 12 is an inverted "convex" shape. A servo motor is detachably installed inside the internal groove 13, and the servo motor provides a rotational power source. The working principle of the servo motor mainly depends on pulse positioning and a closed-loop control system. When the servo motor receives a pulse, it will rotate a corresponding angle, thereby achieving precise displacement control. Since the servo motor itself has the function of emitting pulses, it will emit a corresponding number of pulses for each rotation angle, forming a closed loop with the received pulses, thereby precisely controlling the rotation of the motor and achieving high-precision positioning with an accuracy of up to 0.001 mm. The above is public technology and will not be elaborated below.

[0023] Part of the clamping structure 2 is inserted into the clamping table 1. The clamping structure 2 includes a bottom plate 26 detachably fixed inside the clamping table 1. The bottom of the top plate 23 and the internal groove 13 are installed by bolts. A partition plate 28 fixed to the top of the bottom plate 26 has a circular hollow cross-section design, and the partition plate 28 and the bottom plate 26 are in a welded relationship.

[0024] There is a driving gear 27 rotating around its own center inside the partition plate 28. The driving gear 27 is connected to the servo motor, and the servo motor provides a power source for rotation. The top end of the driving gear 27 is rotatably connected to a detachable top plate 23. The bottom of the driving gear 27 and the output end of the servo motor are detachably connected. The circumferential side of the bottom of the top plate 23 and the circumferential side of the top of the partition plate 28 are detachably fixed. The diameter of the top plate 23 is smaller than the diameter of the bottom plate 26.

[0025] [[ID=�]]There are multiple arc-shaped grooves 24 on the outside of the partition plate 28. The plane where the lowest point of the arc-shaped groove 24 is located is higher than the plane where the highest point of the bottom plate 26 is located. A circular groove 25 is provided between adjacent arc-shaped grooves 24, and the circular groove 25 and the arc-shaped groove 24 are connected. The height of the driving gear 27 is twice the height of the circular groove 25. A contraction structure 21 is inserted into the arc-shaped groove 24. The contraction structure 21 rotates inside the circular groove 25 and the arc-shaped groove 24. The servo motor drives the driving gear 27 to rotate to drive the contraction structure 21 to open and close. Specifically, when in use, an external power supply is connected, and the servo motor is controlled to operate through the control panel. At this time, the servo motor will drive the driving gear 27 connected to its output end to rotate, and the driving gear 27 will drive the contraction structure 21 to rotate and open and close inside the arc-shaped groove 24 and the arc-shaped groove 24.

[0026] The shrinking structure 21 includes a threaded post 211 connected in the circular groove 25. The threaded post 211 is detachably fixed in the circular groove 25. A secondary moving gear 212 is threadedly sleeved on the surface of the threaded post 211. Both the secondary moving gear 212 and the driving gear 27 are provided with teeth on their surfaces. The teeth between the secondary moving gear 212 and the driving gear 27 mesh with each other. The secondary moving gear 212 moves longitudinally relative to the clamping table 1 on the surface of the threaded post 211.

[0027] The bottom of the secondary gear 212 is detachably fixed with a suction cup wall 213. The suction cup wall 213 has an arc-shaped design and is threaded onto the threaded post 211. Since the suction cup wall 213 is fixed to the secondary gear 212, it will rotate synchronously with the secondary gear 212. Both the suction cup wall 213 and the top of the top plate 23 are bolted with electric suction cups 22. The electric suction cups 22 are driven by a motor to drive an air pump, which draws air from inside the suction cup to form a negative pressure, thereby adsorbing onto the surface of the object. The above is the disclosed technology and will not be described in detail below. Specifically, there are four suction cup walls 213, and the four suction cup walls 213 can be spliced ​​into a complete circle. The diameter of the complete circle is larger than the diameter of the bottom plate 26 and smaller than the diameter of the top plate 23. During use, the servo motor drives the drive gear 27 to rotate, which in turn drives the secondary gear 212 to rotate, causing the suction cup walls 213 to open and close.

[0028] The built-in slot 13 includes a first slot 131 and a second slot 132. The first slot 131 is located above the second slot 132. Both the first and second slots 132 have circular cross-sections. The diameter of the first slot 131 is larger than the diameter of the second slot 132. The second slot 132 is used to install the servo motor. The diameter of the first slot 131 is larger than the diameter of the base plate 26, and the diameter of the second slot 132 is smaller than the diameter of the base plate 26. The second slot 132 is used to place the servo motor and provide a rotational power source for the drive gear 27.

[0029] The effect achieved by the entire embodiment is as follows: First, the aircraft part to be clamped is placed on the electric suction cup 22. Then, the electric suction cup 22 is activated. The electric suction cup 22 drives an air pump through a motor to draw air out of the suction cup, forming a negative pressure, thereby adsorbing the bottom of the aircraft part. If the size of the aircraft part changes, the servo motor can be controlled through the control panel to rotate the active gear 27. At this time, the active gear 27 will drive the secondary gear 212 to rotate under the action of the teeth. The secondary gear 212 will drive the suction cup wall 213 to rotate and open or close to a suitable size to adsorb and clamp the aircraft part. When the secondary gear 212 rotates, the secondary gear 212 and the threaded post 211 are threadedly connected. When the secondary gear 212 rotates, it will move up and down on the threaded post 211 to adjust the aircraft part with different bottom heights. Since the height of the active gear 27 is twice the height of the circular groove 25, the active gear 27 and the circular groove 25 will not fall off.

[0030] Example 2: Figure 1-5 As shown, this embodiment also provides a clamping platform for processing aircraft parts. The clamping platform includes a baffle 11, which is detachably mounted on the surface of the clamping table 1 on one side of the storage plate 12 to limit the movement of waste materials.

[0031] The clamping platform 1 also has an air hole 14, which is located inside the shelf 12. The air hole 14 is connected to the built-in groove 13. A rectangular groove is opened inside the shelf 12 on the side away from the air hole 14. The rectangular groove is connected to the air hole 14 and the built-in groove 13 and passes through the side wall of the shelf 12. Specifically, during use, the air hole 14 can be aligned with the external air blowing structure. Since the air hole 14 is connected to the built-in groove 13 and the rectangular groove, it will blow out the debris inside the air hole 14 and the built-in groove 13 to avoid the debris affecting the overall use of the clamping structure 2.

[0032] Working Principle: When using this type of aircraft part processing clamping platform, an external power supply is used. First, the aircraft part to be clamped is placed on the electric suction cup 22. The electric suction cup 22 is then activated. The electric suction cup 22, driven by a motor, uses an air pump to extract air from inside the suction cup, creating negative pressure, which then adheres to the bottom of the aircraft part. If the size of the aircraft part changes, the servo motor can be controlled via the control panel. The servo motor drives the drive gear 27 to rotate. The drive gear 27, under the action of its teeth, drives the secondary gear 212 to rotate. The secondary gear 212 then drives the suction cup wall 213 to rotate, open, or close to a suitable size, thus clamping the aircraft part. The device parts are adsorbed and clamped. When the secondary gear 212 rotates, the secondary gear 212 and the threaded column 211 are threadedly connected. When the secondary gear 212 rotates, it will move up and down on the threaded column 211 to adjust the aircraft parts at different bottom heights. Since the height of the drive gear 27 is twice the height of the circular groove 25, the drive gear 27 and the circular groove 25 will not fall off. Secondly, during use, the external blowing structure can be aligned with the air hole 14. Since the air hole 14 is connected to the internal groove 13 and the rectangular groove, it will blow out the debris inside the air hole 14 and the internal groove 13 to avoid the debris affecting the overall use of the clamping structure 2, and finally complete the work.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
