Description

Technical Field

[0001] This utility model belongs to the field of aerospace parts processing technology, specifically relating to a dustproof grinding device for aerospace parts processing. Background Technology

[0002] Grinding of aerospace parts is a crucial process in the aerospace manufacturing field (such as plate-shaped and columnar parts). Its main purpose is to remove burrs, flash, and rough parts from the surface of the parts to ensure that the parts have accurate dimensions, smooth surfaces, and good assembly performance. Grinding equipment is required when grinding aerospace parts.

[0003] When polishing aerospace parts, polishing machines are used. However, existing polishing machines do not have dustproof mechanisms, and the dust generated during polishing will disperse into the air, increasing maintenance costs (e.g., it will accumulate on the equipment surface, increasing maintenance costs). Therefore, a technical measure is proposed to solve the problem that existing polishing machines do not have dustproof mechanisms, and the dust generated during polishing will disperse into the air, increasing maintenance costs. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dustproof grinding device for processing aerospace parts, which aims to solve the problem that the existing grinding machines do not have a dustproof mechanism, and the dust generated during grinding will be dispersed into the air, increasing maintenance costs.

[0006] (2) Technical solution

[0007] To address the aforementioned technical problems, this utility model provides a dustproof grinding device for aerospace parts processing, comprising a main body and a grinding disc. A dustproof component is fixedly fitted onto the lower exterior of the main body. A motor is installed inside the upper part of the main body, connected to a vertical rod. A locking block is connected to the lower part of the vertical rod, and a bolt is threaded through the side of the locking block. An mounting plate is installed on the upper surface of the grinding disc, and a locking post is installed in the middle of the upper surface of the mounting plate. Thanks to the dustproof component, the grinding device can absorb the dust generated during grinding, achieving a dustproof function. This prevents the dust generated during grinding from dispersing into the air, thus preventing dust from falling onto the equipment surface, avoiding increased equipment maintenance costs, and also preventing operators from inhaling dust, protecting their health. Simultaneously, the threadedly connected interface pipe and connecting pipe facilitate the emptying of dust from inside the pipe body.

[0008] Furthermore, the side of the locking pin is provided with a threaded hole, the locking pin and the locking block are properly fitted together, and the bolt is threadedly fitted to the threaded hole.

[0009] Furthermore, the mounting plate and grinding disc are located directly below the dustproof component.

[0010] Furthermore, a top block is installed on the upper part of the main body, and a handle is installed at the middle position of the upper surface of the top block.

[0011] Furthermore, a main rod is installed on the side of the top block, and a connecting wire runs through the main rod.

[0012] Furthermore, the dustproof component includes a dust collection disc, which is fixedly installed on the lower part of the main body. The lower surface of the dust collection disc has multiple sets of evenly distributed air holes. A vertical pipe is installed through the upper surface of the dust collection disc, and a connecting pipe is installed through the side of the vertical pipe. The port of the connecting pipe is threaded.

[0013] Furthermore, the dustproof assembly also includes a tube body that tapers towards one end of the vertical pipe, and an interface tube is rotatably installed at the end of the tube body facing the vertical pipe, the interface tube being threadedly adapted to the connecting pipe.

[0014] Furthermore, a middle plate is provided in the middle of the pipe body, through which the pipe body passes. A filter screen is movably installed in the middle plate with internal threads. A protective net is provided at the end of the pipe body away from the vertical pipe. A fan is installed inside the pipe body, close to the protective net.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a handle that makes it easy to hold the device.

[0018] The use of locking blocks, locking posts, and bolts facilitates the replacement of the grinding disc. When the grinding disc needs to be replaced, the bolts are released from the connection between the locking blocks and locking posts, and then a new mounting plate and grinding disc are replaced. The bolts are then used to fix the locking posts and locking blocks in place.

[0019] By incorporating dustproof components, the grinding device can absorb the dust generated during grinding, thus preventing the dust from dispersing into the air and settling on the equipment surface, avoiding increased equipment maintenance costs. It also prevents operators from inhaling dust, protecting their health. The threaded, movable interface pipe and connecting pipe facilitate emptying the dust from inside the pipe. Activating the fan sequentially draws the grinding dust into the air vent, suction disc, vertical pipe, connecting pipe, interface pipe, and pipe body. The dust entering the pipe body is trapped inside by the filter screen. After grinding, rotating the interface pipe disengages it from the connecting pipe, allowing the dust inside the pipe to be emptied. When the filter screen needs replacement or cleaning, it is removed from the middle plate. Attached Figure Description

[0027] 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.

[0028] This specific embodiment is a dustproof grinding device for machining aerospace parts, and its structural schematic diagram is shown below. Figure 1 , Figure 2As shown, the device includes a main body 1 and a grinding disc 5. A dustproof assembly 2 is fixedly fitted onto the lower part of the main body 1. A motor 11 is installed inside the upper part of the main body 1, and a vertical rod 12 is connected to the motor 11. A locking block 13 is connected to the lower part of the vertical rod 12, and a bolt 14 is threaded through the side of the locking block 13. An mounting plate 8 is installed on the upper surface of the grinding disc 5, and a locking post 9 is installed in the middle of the upper surface of the mounting plate 8. A threaded hole 10 is opened on the side of the locking post 9, which fits properly with the locking block 13. The bolt 14 is threadedly fitted into the threaded hole 10. The mounting plate 8 and the grinding disc 5 are directly below the dustproof assembly 2. A top block 3 is installed on the upper part of the main body 1, and a handle 4 is installed in the middle of the upper surface of the top block 3. A main rod 6 is installed on the side of the top block 3, and a connecting rod 6 is threaded through the main rod 6. Wiring 7: When actually grinding aerospace parts, first fix the aerospace parts on the operating table, then connect the grinding device to the power supply. Then hold the main rod 6 with one hand and the handle 4 with the other hand, and then start the dustproof component 2 and the motor 11. The dustproof component 2 will absorb the dust generated during grinding. The motor 11 will start and drive the vertical rod 12 to rotate. The rotation of the vertical rod 12 will drive the locking block 13, locking post 9, mounting plate 8 and grinding disc 5 to rotate. The grinding disc 5 will rotate and grind the aerospace parts. When the grinding disc 5 needs to be replaced, release the bolt 14 from the connection between the locking block 13 and the locking post 9, and then replace the new mounting plate 8 and grinding disc 5. Use the bolt 14 to fix the locking post 9 and the locking block 13.

[0029] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, the dustproof component 2 includes a suction disc 201, which is fixedly installed on the lower part of the main body 1. Multiple sets of evenly distributed air holes 210 are opened on the lower surface of the suction disc 201. A vertical pipe 204 is installed through the upper surface of the suction disc 201, and a connecting pipe 207 is installed through the side of the vertical pipe 204. The port of the connecting pipe 207 is threaded. The dustproof component 2 also includes a pipe body 202, which converges towards the end of the vertical pipe 204. An interface pipe 208 is rotatably installed at the end of the pipe body 202 facing the vertical pipe 204. The interface pipe 208 is threadedly matched with the connecting pipe 207. A middle plate 203 is provided in the middle of the pipe body 202, through which the pipe body 202 passes. A filter screen 209 is movably installed on the internal thread of the middle plate 203. A protective net 206 is provided at the end of the pipe body 202 away from the vertical pipe 204. A fan 205 is installed inside the body 202. The fan 205 is close to the protective net 206. When the fan 205 is turned on, the dust generated during grinding is sucked into the air hole 210. Then the dust enters the dust suction disc 201, the vertical pipe 204, the connecting pipe 207, the interface pipe 208, and the pipe body 202 in sequence. The dust entering the pipe body 202 is blocked by the filter screen 209 and is retained inside the pipe body 202. After grinding is completed, the interface pipe 208 (the interface pipe 208 is rotatably connected to the pipe body 202) is rotated to disengage the interface pipe 208 from the connecting pipe 207. Then the dust inside the pipe body 202 is poured out (the fan 205 is powered externally, and a certain length of wire is reserved for easy removal of the entire pipe body 202). When the filter screen 209 needs to be replaced or cleaned, the filter screen 209 is removed from the middle plate 203.

[0030] Working principle: When actually grinding aerospace parts, first fix the aerospace parts on the operating table, then connect the grinding device to the power supply, then hold the main rod 6 with one hand and the handle 4 with the other hand, then start the dustproof component 2 and the motor 11. The dustproof component 2 will absorb the dust generated during grinding, and the motor 11 will start to drive the vertical rod 12 to rotate. The rotation of the vertical rod 12 will drive the locking block 13, locking post 9, mounting plate 8 and grinding disc 5 to rotate. The grinding disc 5 will grind the aerospace parts. When the grinding disc 5 needs to be replaced, release the bolt 14 from the connection between the locking block 13 and the locking post 9, then replace the mounting plate 8 and the grinding disc 5 with a new one, and use the bolt 14 to fix the locking post 9 and the locking block 13. The handle 4 is designed to make it easy to hold the device, and the locking block 13, locking post 9 and bolt 14 are designed to make it easy to replace the grinding disc 5.

[0031] The dustproof component 2 works as follows: Fan 205 is activated to draw grinding dust into air vent 210. The dust then sequentially enters the suction disc 201, vertical pipe 204, connecting pipe 207, interface pipe 208, and pipe body 202. Dust entering pipe body 202 is trapped inside by filter 209. After grinding, interface pipe 208 (rotatably connected to pipe body 202) is rotated to disengage it from connecting pipe 207. The dust inside pipe body 202 is then emptied. (Fan 205 is powered externally.) Leave a certain length of wire to facilitate the removal of the entire tube 202. When the filter 209 needs to be replaced or cleaned, the filter 209 can be removed from the middle plate 203. With the dustproof component 2, the grinding device can absorb the dust generated during grinding, thus achieving the dustproof function. This prevents the dust generated during grinding from dispersing into the air and thus prevents the dust from falling onto the equipment surface, avoiding increased equipment maintenance costs. It also prevents operators from inhaling dust, protecting the health of the operators. At the same time, the threaded movable interface tube 208 and connecting tube 207 facilitate the emptying of dust from inside the tube 202.
