[0024] The application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely intended to explain the related application, but not to limit the application. In addition, it should be noted that only parts related to the application are shown in the drawings for the convenience of description.

[0025] It should be noted that the embodiments and features in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] One embodiment of the present application is to refer to Figs. 1-6 A crescent pattern scraping device, comprising: a fixing table 100 for fixing a component to be scraped 400, the fixing table 100 being rotationally connected with a first shaft 110; a moving table 200 located above the fixing table 100; and a crescent pattern scraping mechanism 300 comprising a driving mechanism 310, a transmission mechanism 320 and a scraping assembly 330, the crescent pattern scraping mechanism 300 being connected to the moving table 200, the scraping assembly 330 comprising a first scraping head 331 and a second scraping head 333, the first scraping head 331 being provided with a plurality of first elastic scraping plates 332 arranged in a stepped manner on a side facing the fixing table 100, the second scraping head 333 being provided with a plurality of second elastic scraping plates arranged in a stepped manner on a side facing the fixing table 100, the driving mechanism 310 driving the first scraping head 331 and the second scraping head 333 to rotate synchronously around the first shaft 110 through the transmission mechanism 320, so as to form a crescent pattern on the surface of the component to be scraped 400.

[0027] In the embodiment of the present application, the fixing table is placed on the ground, and the component to be scraped is fixed on the fixing table. The fixing table can be provided with a plurality of fixing blocks, and the component to be scraped is fixed by the fixing blocks, so as to avoid movement of the component to be scraped during scraping and ensure the stability of scraping.

[0028] The moving table is located above the fixing table, and the crescent pattern scraping mechanism is arranged on the moving table. The moving table can move in the horizontal direction to change the relative position of the crescent pattern scraping mechanism and the component to be scraped, so that the crescent pattern scraping mechanism faces different positions of the component to be scraped. The moving table can move in the vertical direction to change the distance between the crescent pattern scraping mechanism and the component to be scraped. By moving the moving table in the vertical direction, the crescent pattern scraping mechanism is brought into contact with or separated from the component to be scraped, so as to facilitate the crescent pattern scraping mechanism to scrape a crescent pattern on the surface of the component to be scraped.

[0029] When the mobile table drives the crescent pattern scraping mechanism to move downwards, the first scraping head and the second scraping head abut against the surface of the component to be scraped. Since the first scraping head is provided with a plurality of first elastic scraping plates arranged in a stepped manner, and the second scraping head is provided with a plurality of second elastic scraping plates arranged in a stepped manner, the first scraping head and the second scraping head are arranged in a face symmetry. When the mobile table is in the lowest position, the plurality of first elastic scraping plates and the plurality of second elastic scraping plates are in contact with the surface of the component to be scraped. At this time, the first elastic scraping plates with a longer length are deformed more than the first elastic scraping plates with a shorter length, and the second elastic scraping plates with a longer length are deformed more than the second elastic scraping plates with a shorter length. With the driving mechanism driving the first scraping head and the second scraping head to rotate synchronously around the first shaft, in the rotation process of the first scraping head, the first elastic scraping plates with a shorter length will be separated from the component to be scraped first, and the first elastic scraping plates with a longer length will be separated from the component to be scraped later. Since the plurality of first elastic scraping plates are arranged in a stepped manner, with the rotation of the first scraping head, the plurality of first elastic scraping plates will form a half-moon pattern on the surface of the component to be scraped. Similarly, in the rotation process of the second scraping head, the second elastic scraping plates with a shorter length will be separated from the component to be scraped first, and the second elastic scraping plates with a longer length will be separated from the component to be scraped later. Since the plurality of second elastic scraping plates are arranged in a stepped manner, with the rotation of the second scraping head, the plurality of second elastic scraping plates will form a half-moon pattern on the surface of the component to be scraped. Further, the driving mechanism drives the first scraping head and the second scraping head to rotate synchronously around the first shaft through the transmission mechanism to form a crescent pattern on the surface of the component to be scraped. The mobile table can change the position of the crescent pattern scraping mechanism relative to the component to be scraped, so that the crescent pattern scraping mechanism scrapes a crescent pattern at different positions on the surface of the component to be scraped, thereby reducing the labor intensity of workers.

[0030] Further, the transmission mechanism 320 includes a sliding block 321, a first connecting rod 322, a second connecting rod 323, a first rotating rod 340 and a second rotating rod 350. One end of the first connecting rod 322 is rotationally connected with the sliding block 321, the other end of the first connecting rod 322 is rotationally connected with the first rotating rod 340. One end of the second connecting rod 323 is rotationally connected with the sliding block 321, the other end of the second connecting rod 323 is rotationally connected with the second rotating rod 350. The first rotating rod 340 and the second rotating rod 350 are respectively fixedly connected with the first shaft 110. The first scraping head 331 is fixedly connected with one end of the first rotating rod 340 close to the fixed table 100. The second scraping head 333 is fixedly connected with one end of the second rotating rod 350 close to the fixed table 100. The driving mechanism 310 drives the sliding block 321 to reciprocate in the vertical direction.

[0031] In embodiments of the present invention, the slider is slidably connected to the moving table, and the slider can slide vertically, but is not limited to this. One end of the first connecting rod is rotatably connected to the slider, and the other end of the first connecting rod is rotatably connected to the first rotating rod. One end of the second connecting rod is rotatably connected to the slider, and the other end of the second connecting rod is rotatably connected to the second rotating rod. When the slider slides relative to the moving table, the first connecting rod drives the first rotating rod to rotate, which in turn drives the first scraping head to rotate around the first axis; the second connecting rod drives the second rotating rod to rotate, which in turn drives the second scraping head to rotate around the first axis. This achieves synchronous movement of the first and second scraping heads, resulting in a simple and reliable structure. The driving mechanism drives the slider to slide back and forth vertically, causing the first and second scraping heads to reciprocate.

[0032] Furthermore, the first rotating rod 340 includes a first connecting part 341, a first rotating part 343, and a first fixing part 344 connected in sequence. The first connecting part 341 is rotatably connected to the first connecting rod 322 via a first rotating shaft. The first shaft 110 passes through the first rotating part 343, and the first scraping head 331 is fixedly connected to the first fixing part 344. The second rotating rod 350 includes a second connecting part 351, a second rotating part 353, and a second fixing part 354 connected in sequence. The second connecting part 351 is rotatably connected to the second connecting rod 323 via a second rotating shaft. The first shaft 110 passes through the second rotating part 353, and the second scraping head 333 is fixedly connected to the second fixing part 354.

[0033] In an embodiment of the present invention, the first shaft passes through the first rotating part and is fixedly connected to the first rotating part, ensuring the reliability of the connection between the first shaft and the first rotating part. The first shaft passes through the second rotating part and is fixedly connected to the second rotating part, ensuring the reliability of the connection between the first shaft and the second rotating part. The first connecting part bends toward the second connecting part, and the first fixing part bends toward the second fixing part, facilitating the drive mechanism to drive the first rotating rod and the second rotating rod to rotate.

[0034] Furthermore, the first connecting part 341 is provided with a first sliding shaft 342, and the moving stage 200 includes a first fixed plate 210 and a second fixed plate 220 disposed opposite to each other. The first fixed plate 210 and the second fixed plate 220 are respectively provided with a first sliding groove 230, and the two ends of the first sliding shaft 342 slide within the first sliding groove 230 respectively. The second connecting part 351 is provided with a second sliding shaft 352, and the first fixed plate 210 and the second fixed plate 220 are respectively provided with a second sliding groove 240, and the two ends of the second sliding shaft 352 slide within the second sliding groove 240 respectively.

[0035] In embodiments of the present invention, the sliding fit between the first sliding shaft and the first sliding groove restricts the rotation path of the first rotating rod, ensuring the stability of its rotation. Similarly, the sliding fit between the second sliding shaft and the second sliding groove restricts the rotation path of the second rotating rod, ensuring its stability.

[0036] Furthermore, both the first slide 230 and the second slide 240 are configured as arc shapes.

[0037] In an embodiment of the present invention, the first slide groove is arc-shaped, which makes the first slide shaft slide more smoothly within the first slide groove. The second slide groove is arc-shaped, which makes the second slide shaft slide more smoothly within the second slide groove.

[0038] Furthermore, when the slider 321 is at its highest point, the first fixing part 344 is parallel to the second fixing part 354 and the first fixing part 344 is close to the second fixing part 354; when the slider 321 is at its lowest point, the first fixing part 344 and the second fixing part 354 rotate and separate around the first axis 110 respectively.

[0039] In an embodiment of the present invention, when the driving mechanism drives the slider to slide vertically, when the slider is at its highest point, the first fixing part and the second fixing part are parallel and the first fixing plate is close to the second fixing part. This is the initial position for scraping out the crescent pattern, which can avoid gaps in the middle of the crescent pattern. When the slider is at its lowest point, the first fixing part and the second fixing part rotate and separate around the first axis. With the movement of the first fixing part and the second fixing part, the first scraping head and the second scraping head are driven to rotate synchronously around the first axis, forming a crescent pattern on the surface of the part to be scraped.

[0040] Furthermore, the slider 321 slides between the first fixed plate 210 and the second fixed plate 220. The first fixed plate 210 and the second fixed plate 220 are respectively provided with third sliding grooves, and the slider 321 is partially placed in the third sliding grooves. This ensures the stability and reliability of the sliding connection between the slider and the moving stage.

[0041] Furthermore, the drive mechanism 310 is a cylinder, which includes a cylinder body and a piston rod. The cylinder body is fixedly connected to the moving table, and the piston rod is rotatably connected to the slider. By extending and retracting the piston rod, the first and second scraping heads are driven to rotate synchronously around the first axis, resulting in a simple and reliable structure.

[0042] Furthermore, the mobile station 200 is fixedly connected to the reference station 250.

[0043] In an embodiment of the present invention, the flatness of the reference platform is high. Before the crescent pattern scraping of the part to be scraped, pigment can be applied to the reference platform. The moving platform drives the reference platform to move until it contacts the part to be scraped, so that the pigment on the reference platform is transferred to the surface of the part to be scraped. The workers can judge the degree of scraping of the surface of the part by observing the distribution of pigment on the surface of the part to be scraped, which further reduces the labor intensity of the workers.

[0044] Another embodiment of the present invention is as follows, referring to Figs. 1-6The crescent-pattern scraping method using a crescent-pattern scraping device includes the following steps: S10, fixing the part 400 to be scraped 100 on the fixed table 100; S20, moving the moving table 200 horizontally so that the crescent-pattern scraping mechanism 300 is directly above the part 400 to be scraped; S30, moving the moving table 200 lowering so that the first scraping head 331 and the second scraping head 333 are in contact with the surface of the part 400 to be scraped; S40, the driving mechanism 310 drives the first scraping head 331 through the transmission mechanism 320. The first scraping head 331 and the second scraping head 333 rotate synchronously around the first axis 110 to form a crescent pattern on the surface of the part to be scraped 400; S50, the moving table 200 rises, causing the first scraping head 331 and the second scraping head 333 to detach from the surface of the part to be scraped 400, and the moving table 200 moves horizontally, causing the first scraping head 331 and the second scraping head 333 to detach from the surface of the part to be scraped 400; S60, steps S20 to S50 are repeated to form multiple crescent patterns on the part to be scraped 400.

[0045] In an embodiment of the present invention, a fixed platform is placed on the ground, and the part to be scraped is fixed on the fixed platform. The fixed platform may be provided with multiple fixing blocks to fix the part to be scraped, thereby preventing the part to be scraped from moving during the scraping process and ensuring the stability of the scraping process.

[0046] The movable stage is located above the fixed stage. A crescent-shaped scraping mechanism is installed on the movable stage. The movable stage can move horizontally to change the relative position of the crescent-shaped scraping mechanism and the part to be scraped, allowing the scraping mechanism to face different positions on the part. The movable stage can also move vertically to change the distance between the scraping mechanism and the part. This vertical movement causes the scraping mechanism to contact or disengage from the part, facilitating the scraping of the crescent-shaped pattern onto the surface of the part.

[0047] As the moving table moves the crescent-pattern scraping mechanism downwards, the first and second scraping heads come into contact with the surface of the part to be scraped. The first scraping head has multiple first elastic scraping plates arranged in a stepped pattern, and the second scraping head has multiple second elastic scraping plates arranged in a stepped pattern. The first and second scraping heads are symmetrically arranged facing each other. When the moving table is at its lowest position, all the first and second elastic scraping plates are in contact with the surface of the part to be scraped. At this point, the longer first elastic scraping plates deform more than the shorter ones, and the longer second elastic scraping plates deform more than the shorter ones. As the drive mechanism drives the first and second scraping heads to rotate synchronously around the first axis, during the rotation of the first scraping head, the shorter first elastic scraping plate detaches from the part to be scraped first, followed by the longer first elastic scraping plate. Since the multiple first elastic scraping plates are arranged in a stepped manner, they form a crescent pattern on the surface of the part to be scraped as the first scraping head rotates. Similarly, during the rotation of the second scraping head, the shorter second elastic scraping plate detaches from the part to be scraped first, followed by the longer second elastic scraping plate. Again, since the multiple second elastic scraping plates are arranged in a stepped manner, they form a crescent pattern on the surface of the part to be scraped as the second scraping head rotates. This achieves the goal of the drive mechanism, through the transmission mechanism, driving the first and second scraping heads to rotate synchronously around the first axis, forming a crescent pattern on the surface of the part to be scraped. The moving table can change the position of the crescent pattern scraping mechanism and the part to be scraped, so that the crescent pattern scraping mechanism can scrape crescent patterns at different positions on the surface of the part to be scraped, reducing the labor intensity of workers.

[0048] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
