Description

Technical Field

[0001] This utility model belongs to the field of sealing component processing technology, specifically relating to a trimming device for aerospace sealing components. Background Technology

[0002] Seals are materials or parts used to prevent fluid or solid particles from leaking between adjacent mating surfaces and to prevent external impurities from entering the interior of machinery and equipment. In actual production, rubber seals are the most common. After production, these seals need to be trimmed to remove any remaining burrs, especially in the aerospace field, where the precision requirements for parts are very high, making the trimming of seals even more important.

[0003] A trimming machine for rubber seals, patent publication number CN218341732U, defines the reference surface of the device by setting a positioning plate, thereby limiting the processing route of the device. Then, a grinding disc is set to rotate under the drive of a motor. The two sides of the grinding disc grind and trim the workpiece, which increases the working area of ​​trimming, improves the trimming efficiency, and saves processing time.

[0004] However, in actual operation, although the trimming machine for rubber seals in this utility model increases the working area for trimming, the seals are fixed in place, so it is still difficult to perform a complete trimming and grinding operation on the entire seal in one go, thus affecting the trimming efficiency. In addition, a lot of debris will inevitably be generated during the grinding and trimming process, and if this debris is not dealt with in time, it will easily accumulate in the processing area of ​​the device, affecting subsequent processing operations. Utility Model Content

[0005] The purpose of this invention is to provide a trimming device for aerospace sealing components to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A trimming device for aerospace sealing components, comprising a device body, a trimming mechanism on the device body, a positioning mechanism on the device body, a placement frame, a placement frame fixedly connected to one side of the device body, two moving blocks slidably connected inside the placement frame, a connecting shaft rotatably connected to the moving blocks, a positioning wheel fixedly connected to the connecting shaft, a second motor on one side of the placement frame, a lead screw connected to the transmission end of the second motor, the lead screw rotatably connected inside the placement frame, the lead screw threadedly connected to the two moving blocks, and the thread directions on both sides of the lead screw being opposite, a third motor on one of the moving blocks, the transmission end of the third motor connected to the corresponding connecting shaft, and a collecting mechanism on the device body.

[0007] As a preferred embodiment, the trimming mechanism includes a first motor which is installed on the device main body. A grinding wheel is rotatably connected to the device main body, and the driving end of the first motor is connected to the grinding wheel.

[0008] As a preferred embodiment, the overall shape of the moving block is L-shaped, and the cross-section of the positioning wheel is in the shape of a "work" character.

[0009] As a preferred embodiment, the collection mechanism includes a moving frame which is slidably connected inside the device main body. A collection box is slidably connected inside the moving frame.

[0010] As a preferred embodiment, one side of the collection box is fixedly connected with a handle, and the handle is in the shape of a "U".

[0011] As a preferred embodiment, an electric push rod and a plurality of telescopic sleeve rods are provided inside the device main body. The output end of the electric push rod is connected to the moving frame, and the tops of the plurality of telescopic sleeve rods are all connected to the moving frame.

[0012] As a preferred embodiment, a protection mechanism is provided on the device main body. The protection mechanism includes a fixed block. Two fixed blocks are fixedly connected to the device main body. A protection plate is rotatably connected to one of the fixed blocks. The protection plate is lapped on the other fixed block, and a handle is fixedly connected to the protection plate.

[0013] As a preferred embodiment, a plurality of supports are fixedly connected to the bottom of the device main body, and the plurality of supports are respectively arranged at the four corners of the bottom of the device main body.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In the present utility model, by arranging a first motor, a grinding wheel, a placement frame, a second motor, a丝杆 (it should be noted that "丝杆" is likely a misspelling, assuming it should be "screw rod"), a moving block, a coupling shaft, a positioning wheel and a third motor, the rubber sealing ring to be trimmed is sleeved on the two positioning wheels. Then, the second motor on the placement frame is powered on, and the second motor rotates to drive the screw rod to rotate. As the screw rod rotates, it will drive the two moving blocks to move towards or away from each other, and then带动 (it should be noted that "带动" is likely a misspelling, assuming it should be "drive") the two coupling shafts to move towards or away from each other as well, thereby driving the two positioning wheels to move towards or away from each other until the rubber sealing ring is stretched to the most suitable state for grinding. Then, the first motor can be used to drive the grinding wheel to rotate, thereby grinding and trimming the surface of the rubber sealing ring. Next, the third motor is powered on, and the third motor rotates to drive the coupling shaft on it to rotate together, thereby driving the corresponding positioning wheel to rotate together, and finally driving the rubber sealing ring on the positioning wheel to rotate together, so as to facilitate the all-round grinding and trimming of the rubber sealing ring and ensure the working efficiency of trimming.

[0016] This invention, by setting up a movable frame, a collection box, a handle, an electric push rod, and a telescopic sleeve, allows for the timely collection of debris generated during the grinding and trimming of the rubber sealing ring. When the electric push rod is powered on, it pushes the movable frame, which in turn moves the collection box until it is adjusted to a suitable height. The collection box facilitates the timely collection of debris generated during grinding and trimming. After trimming is complete, the collection box can be easily pulled out using the handle for convenient disposal of the collected debris, thus preventing debris accumulation on the processing area of ​​the device and ensuring smooth subsequent processing operations.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, the trimming mechanism 2 includes a first motor 201. The first motor 201 is mounted on the main body 1 of the device, and a grinding wheel 202 is rotatably connected to the main body 1 of the device. The transmission end of the first motor 201 is connected to the grinding wheel 202. When in use, the first motor 201 is connected to the power supply, and the grinding wheel 202 is rotated by the first motor 201, thereby grinding and trimming the surface of the rubber sealing ring.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, the movable block 304 is L-shaped to facilitate better movement of the movable block 304, and the positioning wheel 306 has an I-shaped cross section to facilitate positioning of the corresponding rubber sealing ring.

[0027] Specifically, such as Figure 1 and Figure 4 As shown, the collection mechanism 4 includes a movable frame 401, which is slidably connected inside the main body 1. A collection box 402 is slidably connected inside the movable frame 401. A handle 403 is fixedly connected to one side of the collection box 402, and the handle 403 is in the shape of a "U". The main body 1 is equipped with an electric push rod 404 and multiple telescopic sleeves 405. The output end of the electric push rod 404 is connected to the movable frame 401, and the tops of the multiple telescopic sleeves 405 are all connected to the movable frame 401. When in use, the electric push rod 404 is powered on, and the electric push rod 404 pushes the movable frame 401, thereby moving the collection box 402 together until the collection box 402 is adjusted to a suitable height. Thus, the collection box 402 facilitates the timely collection of debris generated during grinding and trimming. After the trimming is completed, the collection box 402 can be pulled out in time through the handle 403 for convenient processing of the collected debris.

[0030] The working principle and usage process of this utility model are as follows: In actual operation, the rubber sealing ring that needs to be trimmed can be fitted onto two positioning wheels 306. Then, the second motor 302 on the mounting frame 301 can be powered on. The second motor 302 rotates, driving the lead screw 303 to rotate. As the lead screw 303 rotates, it drives the two moving blocks 304 to move towards or away from each other, which in turn drives the two connecting shafts 305 to move towards or away from each other, thereby driving the two positioning wheels 306 to move towards or away from each other, until the rubber sealing ring is stretched to the most suitable grinding state. Then, the first motor 201 drives the grinding wheel 202 to rotate, thereby grinding and trimming the surface of the rubber sealing ring. Next, the third motor 307 is powered on. The third motor 307 rotates, driving the connecting shaft 305 on it to rotate together, thereby driving the corresponding positioning wheels 306 to rotate together, and finally driving the rubber sealing ring on the positioning wheels 306 to rotate together, thus facilitating all-round grinding and trimming of the rubber sealing ring and ensuring the efficiency of the trimming work.

[0031] During the aforementioned grinding and trimming process of the rubber sealing ring, the electric push rod 404 is powered on, which pushes the moving frame 401, thereby moving the collection box 402 together until the collection box 402 is adjusted to a suitable height.
