[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] In recent years, with the continuous improvement of silicon carbide's material properties and the development of new properties, its applications have gradually shifted from traditional applications to high-performance and high-tech applications. Specifically, silicon carbide applications have expanded from basic functional ceramics, advanced refractory materials, abrasives, and metallurgical raw materials to its use as a structural material due to its high-temperature strength, wear resistance, and corrosion resistance, and its high thermal conductivity and high insulation properties in the electronics industry as substrates and packaging materials for ultra-large-scale integrated circuits. Silicon carbide technology is developing rapidly. China's silicon carbide export market is mainly in Asia and North America, accounting for 70.25% and 23.76% of the global export share, respectively. Although silicon carbide raw materials are now available in large quantities, the development of high-tech products and silicon carbide products with extremely high technological content still holds immense potential.

[0031] Silicon carbide is irregularly shaped, requiring at least one reference surface to be machined on the workpiece before subsequent processing. For irregularly shaped silicon carbide workpieces, tooling is typically used to fix and level them, and then the reference surface is machined with the aid of the tooling to facilitate subsequent processing. However, due to the irregular shape of the silicon carbide workpiece, leveling it using tooling is difficult and yields low accuracy.

[0032] To address the aforementioned problems, this application provides a leveling device, including a support assembly, a rotating assembly, a leveling assembly, and a bearing assembly, for supporting and leveling a workpiece. The support assembly includes a disc-shaped support body, with a positioning shaft on its upper surface, the axis of which is perpendicular to the upper surface of the support body. The rotating assembly, positioned above the support assembly, includes a disc-shaped rotating body. The lower surface of the rotating body includes a positioning hole, the axis of which is perpendicular to the lower surface of the rotating body. The positioning hole and the positioning shaft cooperate to form a rotating pair. The upper surface of the rotating body includes a concave spherical surface and an inclined surface, the concave spherical surface being concentrically arranged with the rotating body, and the inclined surface being close to the edge of the rotating body. A leveling assembly, positioned above the rotating assembly, includes a disc-shaped leveling body, a ball-head slider, and an adjusting member. The lower surface of the leveling body includes a convex spherical surface, which is concentrically arranged with the leveling body. The convex spherical surface and the concave spherical surface cooperate to form a universal joint. The leveling body has a first through hole and a first threaded hole. The first through hole extends from the upper surface of the leveling body to the lower surface of the leveling body. The first threaded hole extends radially from the side of the leveling body and communicates with the first through hole. The ball-head slider passes through the first through hole and contacts the inclined surface. The adjusting member is screwed into the first threaded hole, and one end of the adjusting member contacts the ball-head slider. A support assembly, positioned above the leveling assembly, includes a support platform with a workpiece positioning groove configured to position the workpiece.

[0033] By forming a universal joint through the mating of a convex and concave spherical surface, the leveling assembly can rotate 360 ​​degrees, eliminating the need for repeated workpiece handling and simplifying the leveling operation with high precision. Furthermore, by having the ball-head slider pass through the first through hole and contact the inclined surface, the adjusting component is screwed into the first threaded hole, with one end of the adjusting component contacting the ball-head slider. This facilitates the fixation of the leveled assembly after leveling, preventing workpiece movement during processing and improving the stability after leveling.

Figures 1 to 6 As shown, the leveling device 10 includes a support assembly 100, a rotating assembly 200, a leveling assembly 300, and a load-bearing assembly 400.

[0035] The leveling device 10 is used to support and level the workpiece. Figure 5 The diagram shown is a structural schematic of a workpiece provided in an embodiment of this application. Figure 6 The image shown is an embodiment provided by this application. Figure 5 The workpiece shown is a sectional view. Figure 5 and Figure 6 As shown, workpiece 1 includes a first carbon atom layer 11, a silicon carbide layer 12, and a second carbon atom layer 13. The surface of workpiece 1 is uneven, and the reference plane of workpiece 1 is not parallel to the surface to be processed. Figure 6 As shown, the reference surface can be surface a, and the surface to be machined can be surface b. If the reference surface is surface b, the surface to be machined can also be surface a. In other words, since surface a and surface b are not parallel and are uneven, either surface a or surface b needs to be ground smooth, and the smoothed surface is used as the reference surface, while the other surface is used as the surface to be machined.

[0036] Figure 7 The diagram shown is a structural schematic of a workpiece provided in another embodiment of this application. Figure 7 As shown, the surface of workpiece 1 is uneven.

[0037] The material of workpiece 1 can be ceramic or other silicon carbide materials.

[0038] Figure 8 The diagram shown is a structural schematic of a support component provided in an embodiment of this application. Figure 8 As shown, the support assembly 100 includes a disc-shaped support body 110, and a positioning shaft 120 is provided on the upper surface of the support body 110. The axial direction of the positioning shaft 120 is perpendicular to the upper surface of the support body 110.

[0039] Figure 9 The diagram shown is a structural schematic of a rotating assembly provided in an embodiment of this application. Figure 9 As shown, the rotating assembly 200 is disposed above the support assembly 100 and includes a disc-shaped rotating body 210. The lower surface of the rotating body 210 includes a positioning hole, the axis of which is perpendicular to the lower surface of the rotating body 210. The positioning hole and the positioning shaft 120 cooperate to form a rotating pair. The upper surface of the rotating body 210 includes a concave spherical surface 211 and an inclined surface 212. The concave spherical surface 2111 is concentrically arranged with the rotating body 210, and the inclined surface 212 is close to the edge of the rotating body 210.

[0040] The rotating body 210 can be made of graphite. For example... Figure 3 As shown, the height of the side of the inclined plane 212 closer to the center of the rotating body 210 is greater than the height of the side closer to the edge of the rotating body 210.

[0041] A revolute joint, also known as a slewing joint, is a type of kinematic joint. A revolute joint allows two components (e.g., support assembly 100 and rotating assembly 200) to rotate relative to each other about a common axis. Figure 3 As shown, axis 150 is the common axis of support assembly 100 and rotating assembly 200.

[0042] Figure 10 The image shown is an exploded view of a leveling component provided in an embodiment of this application. Figure 10 As shown, the leveling assembly 300 is disposed above the rotating assembly 200 and includes a disc-shaped leveling body 310, a ball-head slider 320, and an adjusting member 330. The lower surface of the leveling body 310 includes a convex spherical surface 311, which is concentrically arranged with the leveling body 310. The convex spherical surface 311 and the concave spherical surface 211 cooperate to form a universal joint. The leveling body 310 has a first through hole 312 and a first threaded hole 313. The first through hole 312 extends from the upper surface of the leveling body 310 to the lower surface of the leveling body 310. The first threaded hole 313 extends radially from the side of the leveling body 310 and communicates with the first through hole 312. The ball-head slider 320 passes through the first through hole 312 and contacts the inclined surface 212. The adjusting member 330 is screwed into the first threaded hole 313, and one end of the adjusting member 330 contacts the ball-head slider 320.

[0043] The leveling body 310 can be made of graphite. The first through holes 312 can be evenly distributed circumferentially along the leveling body 310. The first threaded holes 313 can be evenly distributed circumferentially along the leveling body 310. There can be multiple ball-head sliders 320 and adjusting members 330. For example, one ball-head slider 320 can be provided in each first through hole 312. Each first threaded hole 313 can be matched with one adjusting member 330.

[0044] A universal joint, also known as a ball joint, is a mechanical connector. Its function is to provide a flexible connection between two planes or two mechanical components, allowing these components to rotate freely. The design principle of a universal joint is relatively simple; it mainly utilizes its mechanical structure to provide a flexible connection between two mechanical components. A ball joint typically consists of an inner ball and an outer ring. Inside the ball is a set of helical cams that engage with grooves in the ring to allow the ball to rotate freely. The universal joint of this application is formed by the engagement of a convex spherical surface 311 and a concave spherical surface 211. The convex spherical surface 311 corresponds to the inner ball, and the concave spherical surface 211 corresponds to the outer ring. The engagement of the convex spherical surface 311 and the concave spherical surface 211 enables relative rotation of the leveling assembly 300 relative to the rotating assembly 200.

[0045] The convex spherical surface 311 and the concave spherical surface 211 have the same curvature. The specific values ​​of the curvature of the convex spherical surface 311 and the concave spherical surface 211 can be set according to actual needs, and this application does not impose specific limitations.

[0046] Figure 11 The diagram shown is a structural schematic of a carrier component provided in an embodiment of this application. Figure 11 As shown, the support assembly 400 is disposed above the leveling assembly 300. The support assembly 400 includes a support platform 410. The support platform 410 has a workpiece positioning groove 411, which is configured to position the workpiece 1.

[0047] like Figure 11 As shown, the support assembly 400 also includes a connecting through hole 420, and the leveling body 310 also includes a connecting threaded hole 314. Bolts pass through the connecting through hole 420 and are screwed into the connecting threaded hole 314, facilitating the fixing of the upper support assembly 400 onto the leveling body 310. The support assembly 400 can be a rotating body, for example, Figure 11 The disk-shaped structure is shown. The connecting through holes 420 can be evenly distributed along the circumference of the supporting component 400.

[0048] The leveling device 10 is used in a surface grinding machine. In other words, the leveling device 10 can be installed on the worktable of the surface grinding machine and used as a tooling for the surface grinding machine.

[0049] By making the convex spherical surface 311 and the concave spherical surface 211 cooperate to form a universal joint, the leveling component 300 can rotate 360 ​​degrees, eliminating the need to repeatedly pick up and put down the workpiece 1. The leveling operation is simple and the leveling accuracy is high.

[0050] In addition, by having the ball head slider 320 pass through the first through hole 312 and contact the inclined surface 212, the adjusting member 330 is screwed into the first threaded hole 313, and one end of the adjusting member 330 contacts the ball head slider 320, which facilitates the fixing of the leveling assembly 300 after leveling, prevents the workpiece 1 from moving during processing, and improves the stability after leveling.

[0051] For example, by rotating the adjustment member 330, a pushing or pulling force can be applied to the ball head slider 320, thereby adjusting the contact position between the ball head slider 320 and the inclined surface 212, and thus adjusting the distance between the leveling component 300 and the rotating component 200.

[0052] For example, the height of the side of the inclined plane 212 closer to the center of the rotating body 210 is greater than the height of the side closer to the edge of the rotating body 210. If the adjusting member 330 rotates in the direction of the ball-head slider 320, a pushing force is applied to the ball-head slider 320, causing it to climb up the inclined plane 212, increasing the distance between the leveling assembly 300 and the rotating assembly 200. If the adjusting member 330 rotates out in the opposite direction of the ball-head slider 320, a pulling force is applied to the ball-head slider 320, causing it to slide down the inclined plane 212, decreasing the distance between the leveling assembly 300 and the rotating assembly 200.

[0053] In some embodiments, such as Figure 3 and Figure 8 As shown, the support assembly 100 also includes a plurality of first balls 130. The upper surface of the support body 110 includes an annular ball groove. The ball groove is concentrically arranged with the support body 110. The plurality of first balls 130 are disposed in the ball groove to reduce the friction between the rotating assembly 200 and the support assembly 100, thereby facilitating the relative rotation between the rotating assembly 200 and the support assembly 100.

[0054] In some embodiments, such as Figure 3 and Figure 8 As shown, multiple first balls 130 are evenly distributed in the ball groove, further reducing the friction between the rotating component 200 and the support component 100, facilitating the relative rotation between the rotating component 200 and the support component 100.

[0055] In some embodiments, the rotating assembly 200 further includes a plurality of second balls 220, and the concave spherical surface 211 of the rotating body 210 has a plurality of circular recesses, in which the plurality of second balls 220 are respectively disposed. The plurality of circular recesses are evenly distributed along the circumference of the rotating body 210, reducing the friction between the leveling assembly 300 and the rotating assembly 200, and facilitating relative rotation between the leveling assembly 300 and the rotating assembly 200. For example, as... Figure 9As shown, multiple circular recesses can be evenly distributed in multiple layers along the rotating body 210, that is, multiple second balls 220 are evenly distributed in multiple layers along the rotating body 210.

[0056] In some embodiments, such as Figure 10 As shown, in the direction parallel to the upper surface of the leveling body 310, the cross-sectional shape of the first through hole 312 includes a rectangle, the ball head slider 320 is strip-shaped, and the cross-sectional shape of the ball head slider 320 includes a rectangle, with one end of the ball head slider 320 including a ball head 321. Figure 3 As shown, the ball head 321 is in contact with the inclined surface 212.

[0057] By making the shape of the cross-section of the first through hole 312 in the direction parallel to the upper surface of the leveling body 310 include a rectangle, and the shape of the cross-section of the ball head slider 320 also include a rectangle, the ball head slider 320 can be limited to prevent it from rotating within the first through hole 312.

[0058] For example, the inclination angle between the inclined plane 212 and the horizontal plane can be set according to actual needs, such as inclination from 5° to 60°, etc., and this application does not make a specific limitation.

[0059] In some embodiments, the leveling assembly 300 further includes a compression spring 340, one end of which is connected to the side of the ball head slider 320, and the other end is connected to the side wall of the first through hole 312.

[0060] By setting a compression spring 340, the ball head slider 320 is elastically connected to the first through hole 312, preventing leveling errors caused by the gap between the ball head slider 320 and the first through hole 312.

[0061] In some embodiments, the leveling assembly 300 further includes a tension spring 350, one end of which is connected to the lower surface of the edge of the leveling body 310, and the other end is connected to the upper surface of the rotating body 210 near the edge of the rotating body 210. By providing the tension spring 350, the leveling assembly 300 and the rotating assembly 200 can form a flexible connection.

[0062] In some embodiments, the rotating assembly 200 further includes a side baffle 230 disposed around the edge of the rotating body 210. The side baffle 230 can prevent dust from entering the contact surface between the rotating assembly 200 and the leveling assembly 300.

[0063] In some embodiments, the support assembly 100 further includes a locking structure 140, which includes a plurality of protrusions 141 fixedly connected to the support body and a locking bolt 142. The plurality of protrusions 141 are evenly distributed on the edge of the upper surface of the support body 110. Each protrusion has a second threaded hole extending radially along the support body 110. The locking bolt 142 is screwed into the second threaded hole and passes through the second threaded hole to contact the side of the rotating body 210. The locking structures 140 are evenly distributed circumferentially along the support assembly 100. For example, there may be two locking structures 140, with an angle of 180° between the two locking structures 140. Alternatively, there may be three locking structures 140, with an angle of 120° between adjacent locking structures 140. By rotating the locking bolt 142, the locking structure 140 can lock the rotating assembly 200.

[0064] In some embodiments, such as Figure 3 As shown, the support assembly 100 also includes a bearing 160, which is mounted on the positioning shaft 120. The positioning hole forms a rotating pair with the positioning shaft 120 through the bearing 160.

[0065] In some embodiments, such as Figure 8 As shown, the support assembly 100 also includes mounting holes 170 to facilitate the mounting of the leveling device 10 onto the surface grinder. Specifically, the leveling device 10 can be mounted onto the surface grinder using bolts. For example, bolts pass through the mounting holes 170 and are screwed onto the worktable of the surface grinder. The mounting holes 170 can be evenly distributed circumferentially along the support assembly 100.
