Description

Technical Field

[0001] This utility model belongs to the field of aerospace manufacturing equipment technology, specifically relating to a quick clamp changing device for lubricating and grease-applying aerospace nuts and bolts. Background Technology

[0002] As critical connecting components in aircraft, aviation nuts and bolts operate in extremely harsh environments, requiring them to withstand high-frequency vibrations, extreme temperature changes, and complex stresses. To ensure their connection reliability and service life, rigorous lubrication and grease treatment must be performed before assembly to reduce the coefficient of friction, prevent corrosion, and minimize wear. With the aviation industry's ever-increasing demands for production efficiency and product quality, traditional clamp-changing methods have become a key bottleneck restricting the upgrading of the lubrication and grease application process.

[0003] In the current aerospace manufacturing industry, lubrication of nuts and bolts often requires applying grease to different surfaces. This necessitates frequent clamp changes in different grease-applying equipment, which significantly reduces equipment utilization and severely impacts overall production efficiency. Furthermore, repeated clamp changes reduce positioning accuracy and can lead to uneven lubrication, affecting the performance and safety of aerospace nuts and bolts. The complex operation requires specialized personnel for tedious adjustments, increasing labor costs and the risk of operational errors, making it difficult to meet the high-efficiency, high-precision requirements of aerospace production. Utility Model Content

[0004] The purpose of this invention is to provide a quick clamp changing device for lubricating and grease-applying aircraft nuts and bolts. By cooperating with a suitable drive mechanism and clamping mechanism, it can achieve quick clamp changing, improve clamp changing efficiency and positioning accuracy, and simplify the operation process.

[0005] The specific technical solution adopted by this utility model is as follows: A quick-change clamping device for lubricating and grease-applying aircraft nuts and bolts includes a frame, a drive mechanism, and a clamping mechanism. The frame is equipped with a worktable and a lubrication assembly. A feeding assembly is fixed to one side of the worktable, and a positioning assembly is fixed to the bottom of the worktable. The lubrication assembly is located on one side of the worktable. The drive mechanism includes a slide rail, which is fixedly connected to the front and rear ends of the frame, and the outer side of the slide rail is slidably connected to the electric slide table. The electric slide table is fixedly connected to the lifting push rod, and the output end of the lifting push rod is fixedly connected to the connecting seat. The clamping mechanism includes a first clamping component, a second clamping component, and a third clamping component. The first clamping component and the second clamping component are fixedly connected to the connecting seat on the same side, and the first clamping component and the second clamping component are symmetrically distributed along the center of the connecting seat. The third clamping component is fixedly connected to the connecting seat on the other side. The process involves feeding the part using the feeding assembly, clamping the part using the first and second clamping assemblies driven by the drive mechanism on one side of the frame, and placing the part into the positioning assembly. The lubrication assembly then lubricates the internal threads and end faces of the part in sequence. Subsequently, the drive mechanism on the other side of the frame drives the third clamping assembly to move the lubricated part to the inspection area, and the inspected parts are then sorted and stored for later use.

[0006] Furthermore, the positioning component includes a positioning block and a support block. The positioning block has a positioning groove and is fixed above the support block. The lower part of the support block is fixedly matched with the output shaft of the reducer.

[0007] Furthermore, the lubrication assembly includes a lubrication nozzle, which is fixedly connected to the output end of the lifting hydraulic rod and is located above the positioning block.

[0008] Furthermore, the feeding assembly includes a feeding slider, which is fixedly connected to the output end of the drive push rod, and the feeding slider is located below the first clamping assembly and the second clamping assembly.

[0009] Furthermore, the first clamping assembly includes a first electric clamp, the output end of which is fixed with an inner clamping head.

[0010] Furthermore, the second clamping assembly includes a second electric clamp, the output end of which is fixed with an outer clamping head.

[0011] Furthermore, the third clamping assembly includes a third electric clamp, the output end of which is fixed with an outer clamping head.

[0013] Furthermore, a collection cylinder is fixed inside the frame, located below the third clamping assembly, and the collection cylinder is divided into a defective product cylinder and a qualified product cylinder.

[0014] The technical effects achieved by this utility model are as follows: This utility model discloses a quick clamp changing device for lubricating aviation nuts and bolts. Through the cooperation of a suitable drive mechanism and clamping mechanism, it can automatically change clamps during the lubrication process of aviation nuts and bolts without much manual intervention, ensuring continuous and stable operation and significantly improving production efficiency. At the same time, it can avoid the positioning instability of manual clamp changing, ensuring accuracy during use.

[0017] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0018] like Figures 1 to 6 As shown, a quick-clamp changing device for lubricating and grease-applying aircraft nuts and bolts is described. Includes frame 10, drive mechanism 20 and clamping mechanism 30; The frame 10 has a worktable 101 and a lubrication component 102 fixed inside. A feeding component 11 is fixed on one side of the worktable 101, and a positioning component 12 is fixed on the bottom of the worktable 101. The lubrication component 102 is located on one side of the worktable 101. The drive mechanism 20 includes a slide rail 21, which is fixedly connected to the front and rear ends of the frame 10. The outer side of the slide rail 21 is slidably connected to the electric slide table 22. The electric slide table 22 is fixedly connected to the lifting push rod 23. The output end of the lifting push rod 23 is fixedly connected to the connecting seat 24. The clamping mechanism 30 includes a first clamping component 31, a second clamping component 32, and a third clamping component 33. The first clamping component 31 and the second clamping component 32 are respectively fixedly connected to the connecting seat 24 on the same side, and the first clamping component 31 and the second clamping component 32 are symmetrically distributed along the center of the connecting seat 24. The third clamping component 33 is fixedly connected to the connecting seat 24 on the other side. The parts are fed by the feeding assembly 11, and the first clamping assembly 31 and the second clamping assembly 32 are driven by the drive mechanism 20 on one side of the frame 10 to clamp the parts and place them into the positioning assembly 12. The lubrication assembly 102 lubricates the internal threads and end faces of the parts in sequence. Then, the third clamping assembly 33 is driven by the drive mechanism 20 on the other side of the frame 10 to move the lubricated parts to the inspection area and separate and store the inspected parts for subsequent use.

[0019] In this embodiment, it should be noted that the bottom of the frame 10 is provided with an anti-slip pad to prevent the equipment from sliding during operation; the inner side of each clamping head in the clamping mechanism 30 is provided with an arc-shaped groove adapted to the aviation nut bolt, and the groove is provided with anti-slip texture to ensure stability during clamping; the electric slide table 22 cooperates with the slide rail 21 to achieve horizontal linear reciprocating movement; the lifting push rod 23 drives the connecting seat 24, which can effectively drive the clamping mechanism 30 fixedly connected to the connecting seat 24 to perform precise vertical movement. This is a conventional technical means. This will not be elaborated further; specifically, the feeding assembly 11 is responsible for conveying the aviation nuts and bolts to be processed to the area below the clamping mechanism 30; the drive mechanism 20 is located on both sides of the frame 10 and drives the clamping mechanism 30 to move precisely through mechanical transmission; wherein, the first clamping assembly 31 and the second clamping assembly 32 work together to place the parts into the positioning assembly 12, and then lubricate the internal threads and the top of the nuts in sequence; the lubricated parts are transferred to the inspection area through the third clamping assembly 33, and after the inspection is completed, the nuts are classified and stored.

[0020] like Figure 2, Figure 3 As shown, the positioning block 121 is fixed to the support block 122, and the two are fixed together by an angular contact bearing, which ensures that it can withstand greater axial force while rotating. The top of the positioning block 121 has a positioning groove that matches the nut bolt for applying grease to the nut bolt. The support block 122 is matched with the output shaft of the reducer, ensuring that the support block 122 can be moved accurately and reducing driving errors. It should be noted that the positioning block 121 is divided into an internal thread lubricated positioning block 121 and an end face lubricated positioning block 121. Preferably, the lubrication assembly 102 includes a lubrication nozzle, which is fixedly connected to the output end of the lifting hydraulic rod and is located above the positioning block 121. When the product moves into the positioning block 121, the lifting hydraulic rod drives the lubrication nozzle to move above the part, thereby effectively lubricating the inside and top of the part.

[0021] Preferably, the feeding assembly 11 includes a feeding slider 111, which is fixedly connected to the output end of the drive push rod, and the feeding slider 111 is located below the first clamping assembly 31 and the second clamping assembly 32. When it is necessary to feed the nut, the feeding slider 111 is controlled to move to the bottom of the feeding cylinder. After the feeding is completed, the feeding slider 111 and the nut are moved to the initial position to ensure that the subsequent clamping mechanism 30 effectively clamps the nut.

[0022] like Figure 5 , Figure 6 As shown, the first clamping assembly 31 includes a first electric clamp 311, and an inner clamping head 312 is fixed at the output end of the first electric clamp 311. The inner clamping head 312 is adapted to the inner diameter of the nut.

[0023] like Figure 6 As shown, the second clamping assembly 32 includes a second electric clamp 321, and an outer clamping head 322 is fixed to the output end of the second electric clamp 321.

[0024] like Figure 4 , Figure 5 As shown, the third clamping assembly 33 includes a third electric clamp 331, and an end clamping head 332 is fixed to the output end of the third electric clamp 331.

[0025] In this embodiment, when lubrication of the nut is required, the drive mechanism 20 drives the first clamping component 31 to place the nut into the positioning block 121, ensuring lubrication loading and effective internal thread lubrication. After internal thread lubrication is completed, the drive mechanism 20 drives the second clamping component 32 to clamp the nut with lubricated internal threads and place it back into the positioning block 121, ensuring effective end face lubrication without affecting the lubrication of the internal threads, thus completing the lubrication repositioning. After end face lubrication is completed, the drive mechanism 20 on the other side drives the third clamping component 33 to clamp the outer wall of the nut and move it to the detection area, ensuring effective detection clamping.

[0026] Preferably, a detection component 13 is also fixed inside the frame 10. The detection component 13 is a CCD detection camera, which can effectively detect the lubrication area of ​​the nut.

[0027] like Figure 2 , Figure 4 As shown, a collection cylinder 14 is also fixed inside the frame 10. The collection cylinder 14 is located below the third clamping assembly 33, and the collection cylinder 14 is divided into a defective product cylinder and a qualified product cylinder.

[0028] The working principle of this utility model is as follows: When lubrication of the nut is required, the drive mechanism 20 controls the first clamping assembly 31 to move the nut placed in the loading slider 111. Then, the first electric clamp 311 drives the inner clamping head 312 to support the internal thread of the nut. After reaching a fixed state, the lifting push rod 23 is controlled to drive the connecting seat 24 and the first clamping assembly 31 to rise, ensuring that the movement avoids the loading slider 111 and stably brings the nut to the positioning block 121 for internal thread lubrication. Then, the lifting push rod 23 drives the first clamping assembly 31 to move, ensuring effective internal thread lubrication. After the internal thread lubrication is completed, the end face needs to be lubricated. The drive mechanism 20 drives the second clamping assembly 32 to move to the position where the internal thread lubrication is completed. Above the thread-lubricated nut, the second electric clamp 321 drives the outer clamping head 322 to clamp the outer side of the nut, which can avoid damaging the structure of the internal thread grease. Then, the internally thread-lubricated nut is transported to the end-face lubrication positioning block 121 to ensure the completion of the transposition work and thus effectively lubricate the end face. After the end face lubrication is completed, the third clamping assembly 33 is moved above the nut by controlling the drive mechanism 20 on the other side. The third electric clamp 331 drives the end clamping head 332 to fix the nut, which can avoid damaging the internal thread and end-face grease structure. Then, the lubricated nut is moved to the bottom of the detection assembly 13. Based on the detection results, the nuts are placed into the collection cylinder 14 to ensure effective differentiation of qualified and unqualified nuts.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
