Abstract
Description
Technical Field
[0001] This invention relates to a grinding equipment, specifically an automatic grinding equipment for burrs on aerospace parts, belonging to the field of aerospace parts processing technology. Background Technology
[0002] In the field of aerospace manufacturing, the surface quality of aerospace components directly affects the operational safety, reliability and service life of the entire aircraft. Since aerospace components are mostly made of high-strength alloys, titanium alloys and other difficult-to-machine materials, and have complex structures (often containing deep holes, narrow slits and irregular curved surfaces), residual burrs are very easy to be generated during the processing. If these burrs are not completely removed, they will cause problems such as assembly interference, stress concentration and fluid channel blockage. In severe cases, they may cause fatigue failure of components. Therefore, it is necessary to remove burrs through grinding processes. At present, the grinding of burrs for aerospace components mostly uses traditional vibratory grinding machines.
[0003] After grinding, the parts and grinding media are mixed in the grinding barrel. Due to the diverse sizes of aerospace parts and the small particle size of the grinding media, traditional separation methods require manual screening or filtration with simple sieves. This not only results in low separation efficiency but also easily causes scratches on the surface of the parts. During the grinding process, the grinding fluid needs to play a role in lubrication, cooling, and assisting cutting. When the parts and grinding media are removed, the grinding fluid in the barrel is prone to splashing with the material movement, which not only contaminates the floor and equipment surfaces of the production workshop but may also pose a potential threat to the safety of operators due to impurities such as metal shavings and abrasive powder contained in the grinding fluid. At the same time, it does not meet the strict environmental protection control requirements in the aerospace manufacturing field. After long-term use, the grinding fluid will mix with a large amount of metal impurities (shavings generated from part grinding), abrasive particles from the grinding media, and other pollutants. Direct discharge will cause resource waste and environmental pollution. Traditional equipment lacks an effective grinding fluid filtration mechanism. The accumulation of pollutants will reduce the lubrication and cooling performance of the grinding fluid, leading to a decrease in grinding efficiency and a deterioration in the surface quality of the parts. At the same time, it is impossible to recycle the grinding fluid, which increases production costs. Summary of the Invention
[0004] The purpose of this invention is to provide an automatic burr grinding device for aerospace parts in order to solve the above-mentioned problems. Therefore, after the parts are ground, it is convenient to separate the parts and grinding media. At the same time, it can also avoid the environmental pollution caused by the splashing of grinding fluid when the parts are taken out. Furthermore, after the grinding is completed, the grinding fluid can be filtered, which not only facilitates the removal of impurities, but also allows the grinding fluid to be reused.
[0005] The present invention achieves the above-mentioned objective through the following technical solution: an automatic burr grinding device for aerospace parts, comprising a base frame, a grinding box mounted on the top of the base frame, a discharge structure mounted on the outer end of the grinding box, the discharge structure including a filter box, a filter box mounted on the outer end of the grinding box, a lifting plate slidably connected inside the grinding box, an inclined plate fixedly connected to the bottom end of the lifting plate, a first filter screen fixedly connected to the top of the grinding box, a sieve fixedly connected to the top of the filter box, a second filter screen slidably connected inside the filter box, a baffle fixedly connected to the top of the filter box, and a filter bag detachably connected to the bottom end of the filter box.
[0006] Preferably, the lifting plate has an overall trumpet-shaped structure, the bottom end of the lifting plate has an inclined structure, and the inclined plate has an overall inclined structure.
[0007] Preferably, the second filter screen has an inclined structure, and the baffle has an annular structure.
[0008] Preferably, a limiting ring is fixedly connected to the top of the outside of the grinding box, and the limiting ring abuts against the screen.
[0009] Preferably, a fixing ring is fixedly connected to the top of the filter bag, and a threaded ring is fixedly connected to the bottom of the filter box. The fixing ring and the threaded ring abut against each other, and a threaded sleeve is threadedly connected to the bottom of the threaded ring. The threaded sleeve abuts against the fixing ring.
[0010] Preferably, a first electric telescopic rod is installed at the bottom of the filter box, the output end of the first electric telescopic rod is fixedly connected to the second filter screen, and a sealing seat is fixedly connected to the bottom of the filter box, and the sealing seat and the output end of the first electric telescopic rod are slidably connected.
[0011] Preferably, a lifting structure is installed inside the grinding box. The lifting structure includes a second electric telescopic rod. The second electric telescopic rod is installed at the bottom of the grinding box, and the output end of the second electric telescopic rod is fixedly connected to the lifting plate.
[0012] Preferably, a guide rod is fixedly connected to the bottom end of the lifting plate, and a guide ring is fixedly connected inside the grinding box, with the guide rod and the guide ring being slidably connected.
[0013] Preferably, a limiting piece is fixedly connected to the bottom end of the guide rod, and the limiting piece and the guide ring are slidably connected.
[0014] Preferably, a vibration assembly is installed at the bottom of the grinding box, and a spring assembly is installed between the base frame and the grinding box.
[0015] The beneficial effects of this invention are as follows: After the parts are ground, the lifting plate slides upward, thus driving the inclined plate to slide and pushing the ground parts and grinding media upward together. A sealing gasket is provided between the grinding box and the inclined plate. The inclined plate allows the parts and grinding media to slide onto the screen. When the lifting plate slides upward, water in the grinding box flows out through the first filter screen. The screen separates the grinding media and parts, and the grinding media falls into the filter box, making it easy to remove and store the parts on the screen. The second filter screen further filters the grinding liquid on the grinding media, thus completing the grinding process. The liquid removes impurities through the filter bag. After filtration, the parts are removed, and the lifting plate descends to the bottom. The second filter slides upward, pushing the grinding media on the second filter upward. Then, the screen is removed, and the tilted second filter allows the grinding media to slide back into the grinding chamber. This facilitates the separation of parts and grinding media after grinding, and also prevents the grinding liquid from splashing and causing environmental pollution when removing parts. Furthermore, the grinding liquid can be filtered after grinding, which not only facilitates the removal of impurities but also allows for the reuse of the grinding liquid. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Please see Figures 1-4 As shown, an automatic burr grinding device for aerospace parts includes a base frame 1, a grinding box 4 mounted on the top of the base frame 1, a discharge structure 2 mounted on the outer end of the grinding box 4, the discharge structure 2 including a filter box 201, a filter box 201 mounted on the outer end of the grinding box 4, a lifting plate 202 slidably connected inside the grinding box 4, an inclined plate 203 fixedly connected to the bottom end of the lifting plate 202, a first filter screen 204 fixedly connected to the top of the grinding box 4, a screen 205 fixedly connected to the top of the filter box 201, a second filter screen 206 slidably connected inside the filter box 201, a baffle 207 fixedly connected to the top of the filter box 201, and a filter bag 208 detachably connected to the bottom end of the filter box 201.
[0023] As a technical optimization of the present invention, the lifting plate 202 is generally in the shape of a trumpet, the bottom end of the lifting plate 202 is in the shape of an inclination, and the inclined plate 203 is generally in the shape of an inclination. Thus, the components and grinding media in the grinding box 4 can be lifted by the inclined plate 203, and the components and grinding media can be automatically slid into the screen 205 by the inclined plate 203.
[0024] As a technical optimization of the present invention, the second filter screen 206 is generally inclined and the baffle 207 is generally annular. Thus, the water contained in the grinding medium can be filtered better through the inclined second filter screen 206, and the filter box 201 can be protected through the baffle 207.
[0025] As a technical optimization of the present invention, a limiting ring 209 is fixedly connected to the top of the outside of the grinding box 4. The limiting ring 209 abuts against the screen 205, thereby limiting the screen 205 by the contact between the limiting ring 209 and the screen 205, and also making it convenient to quickly remove the screen 205.
[0026] As a technical optimization of the present invention, a fixing ring 210 is fixedly connected to the top of the filter bag 208, and a threaded ring 211 is fixedly connected to the bottom of the filter box 201. The fixing ring 210 and the threaded ring 211 abut against each other. A threaded sleeve 212 is threadedly connected to the bottom of the threaded ring 211. The threaded sleeve 212 abuts against the fixing ring 210. Thus, the fixing ring 210 used to install the filter bag 208 is connected by the threaded connection between the threaded sleeve 212 and the threaded ring 211, so that the filter bag 208 can be easily disassembled.
[0027] As a technical optimization of the present invention, a first electric telescopic rod 213 is installed at the bottom of the filter box 201. The output end of the first electric telescopic rod 213 is fixedly connected to the second filter screen 206. A sealing seat 214 is fixedly connected to the bottom of the filter box 201. The sealing seat 214 and the output end of the first electric telescopic rod 213 are slidably connected. Thus, the operation of the first electric telescopic rod 213 drives the second filter screen 206 to slide up and down, thereby pushing out the grinding media on the second filter screen 206. Moreover, the sealing seat 214 can seal and protect the output end of the first electric telescopic rod 213 to prevent the grinding fluid from leaking onto the first electric telescopic rod 213 and causing damage.
[0028] As a technical optimization of the present invention, a lifting structure 3 is installed inside the grinding box 4. The lifting structure 3 includes a second electric telescopic rod 301. The second electric telescopic rod 301 is installed at the bottom of the grinding box 4. The output end of the second electric telescopic rod 301 is fixedly connected to the lifting plate 202. Therefore, the lifting plate 202 is driven to slide up and down by the second electric telescopic rod 301, and the components and grinding media at the top of the lifting plate 202 are pushed out.
[0029] As a technical optimization of the present invention, a guide rod 302 is fixedly connected to the bottom end of the lifting plate 202, and a guide ring 303 is fixedly connected inside the grinding box 4. The guide rod 302 and the guide ring 303 are slidably connected. Therefore, the guide rod 302 and the guide ring 303 can guide and limit the lifting plate 202, and also play a role in positioning the lifting plate 202.
[0030] As a technical optimization of the present invention, a limiting piece 304 is fixedly connected to the bottom end of the guide rod 302. The limiting piece 304 and the guide ring 303 are slidably connected, so that the limiting piece 304 can slide within the guide ring 303, thereby limiting the guide rod 302.
[0031] As a technical optimization of the present invention, a vibration component 5 is installed at the bottom of the grinding box 4, and a spring component 6 is installed between the base frame 1 and the grinding box 4. Therefore, when working, the vibration component 5 is activated, and the spring component 6 enables the components and grinding media inside the grinding box 4 to tumble.
[0032] When using this invention;
[0033] First: Check if the base frame 1 is placed stably to ensure that the equipment does not shake during operation; check if the spring assembly 6 is intact and free from deformation or breakage to ensure the stability of the vibratory grinding; check the sealing of the grinding box 4 and the filter box 201 to confirm that there are no residual impurities, grinding media or metal debris on the inner wall of the box to avoid affecting the grinding effect or scratching the parts; check if the extension and retraction functions of the first electric telescopic rod 213 and the second electric telescopic rod 301 are normal, whether the sliding fit between the guide rod 302 and the guide ring 303 is smooth, whether the limit plate 304 is firm, and whether the sealing seat 214 is undamaged or leaking; confirm that the screen 205, the first filter 204, and the second filter 206 are undamaged or clogged, and that the filter bag 208 is installed in place: fit the fixing ring 210 against the threaded ring 211, tighten the threaded sleeve 212 until the fixing ring 210 is firmly against the thread and there is no looseness; check if the wiring of the vibration assembly 5 is safe; start the test run for 30 seconds to confirm that the vibration frequency is uniform and there is no abnormal noise.
[0034] Then: Place the parts to be ground and the grinding media into the grinding box 4, add water and grinding fluid, and then start the vibration component 5. The spring component 6 causes the parts and grinding media inside the grinding box 4 to tumble, thereby grinding the parts. After the parts are ground, start the second electric telescopic rod 301. The guide rod 302 and guide ring 303 guide the lifting plate 202, and the limiting piece 304 limits the guide rod 302 and guide ring 303. The second electric telescopic rod 301 drives the lifting plate 202 to slide upward, thus driving the inclined plate 203 to slide, pushing the ground parts and grinding media upward together. A sealing gasket is provided between the grinding box 4 and the inclined plate 203. The inclined plate 203 allows the parts and grinding media to slide onto the screen 205. When the lifting plate 202 slides upward, the grinding fluid in the grinding box 4 flows out through the first filter screen 204. The screen 205 can separate the grinding media and parts. The sieve 205 falls into the filter box 201, making it easy to remove and store the parts on the sieve 205. The grinding liquid on the grinding media can be filtered again through the second filter 206. The limiting ring 209 can limit the sieve 205. The grinding liquid removes impurities through the filter bag 208. After filtration is completed and the parts are removed, the second electric telescopic rod 301 is activated to lower the lifting plate 202 to the bottom. Then, the first electric telescopic rod 213 is activated to move the second filter. 206 slides upward, thus pushing the grinding media on the second filter screen 206 upward, and then the screen 205 is removed. The inclined second filter screen 206 allows the grinding media to slide back into the grinding box 4. The sealing seat 214 can waterproof the output end of the first electric telescopic rod 213. When the filter bag 208 needs to be cleaned, the threaded sleeve 212 is rotated. After the threaded sleeve 212 and the threaded ring 211 are separated, the filter bag 208 can be removed for cleaning through the fixing ring 210.
[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
