[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "matched" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, it should be noted that in the description of the present invention, it should be noted that the terminology nouns in the various embodiments, such as "upper", "lower", "front", "back" and other words indicating directions, are only for simplifying the description of the positional relationship based on the drawings in the specification, and do not mean that the components and devices referred to must be operated in accordance with the specific directions and specified operations and methods and structures in the specification. Such directional nouns do not constitute a limitation on the present invention.

[0025] In this article, an XYZ coordinate system is established, and it should be noted that the aforementioned X-axis, Y-axis, and Z-axis are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] like Figure 1-Figure 3 As shown, a grinding device of an embodiment of the utility model includes a hoisting rod 1 and a rotating worktable 2, wherein the hoisting rod 1 is located above the rotating worktable 2, and the rotating worktable 2 is used to place a concave pad 5 to be ground, and the concave pad 5 is eccentrically arranged relative to the rotating worktable 2, and the lower end of the hoisting rod 1 is used to be swingably connected to a convex pad 6 to be ground, and the convex part 61 of the convex pad 6 is in contact with the concave part 51 of the concave pad 5.

[0027] Specifically, the hoisting rod 1 is arranged along the direction indicated by the Z axis, and the hoisting rod 1 can be fixed on the frame. The hoisting rod 1 naturally droops under the action of gravity. The rotating table 2 is a disc-shaped structure that rotates 360° around the Z axis. The concave pad 5 and the convex pad 6 are both circular pads. The concave pad 5 is arranged on the rotating table 2 and its concave part 51 faces upward. The convex pad 6 is swingably connected to the lower end of the hoisting rod 1, and the convex part 61 of the convex pad 6 faces downward. The concave pad 5 is eccentrically arranged with respect to the rotating table 2, that is, the axis of the concave pad 5 does not coincide with the axis of the rotating table 2, and the eccentric distance between the two can be 50 mm. The axis of the rotating table 2, the axis of the hoisting rod 1 and the axis of the convex pad 6 coincide.

[0028] In this embodiment, the rotating worktable 2 drives the concave pad 5 to rotate, and the concave pad 5 drives the convex pad 6 at the lower end of the hanging rod 1 to swing during the rotation. The convex part 61 of the convex pad 6 and the concave part 51 of the concave pad 5 are in contact with each other for grinding. Compared with manual grinding, the efficiency is higher, the grinding quality is more guaranteed, and the appearance of the convex-concave pad after grinding is better. At the same time, because the concave pad 5 is eccentrically arranged relative to the rotating worktable 2, the concave part 51 of the concave pad 5 can contact more convex parts 61 during the rotation process, that is, a smaller concave pad 5 can be used to grind a larger convex pad 6, thereby enhancing the applicability of the grinding device.

[0029] Here, abrasive powder can be added between the contact surfaces of the concave pad 5 and the convex pad 6. The abrasive powder can be continuously replaced during the grinding process to increase the grinding speed until the grinding is completed. After the grinding is completed, the contact rate between the convex pad 6 and the concave pad 5 can reach 80%, and the appearance of the convex and concave pads is better.

[0030] like Figure 1-Figure 3 As shown, optionally, the grinding device further comprises a swing assembly 3 , and the hanging rod 1 is connected to a side of the convex pad 6 facing away from the convex portion 61 via the swing assembly 3 .

[0031] In this embodiment, the side of the convex pad 6 that is away from the convex portion 61, that is, the upper surface of the convex pad 6, is connected to the hanging rod 1 through the swing assembly 3, and the swing assembly 3 can realize the up and down swing of the convex pad 6 relative to the hanging rod 1. Since the axes of the convex pad 6, the hanging rod 1 and the rotating worktable 2 coincide, and the concave pad 5 is offset relative to the rotating worktable 2, when the concave pad 5 rotates, the convex pad 6 is partially swung upward relative to the hanging rod 1 through the swing assembly 3, and then returns to its original position under the action of its own gravity. As the concave pad 5 continues to rotate, the swing grinding of the convex portion 61 of the entire convex pad 6 is realized.

[0032] like Figure 1-Figure 3As shown, optionally, the swing assembly 3 includes a swing shaft 31 and a connecting rod 32, the lower end of the lifting rod 1 is provided with a mounting hole 11, the swing shaft 31 is inserted into the mounting hole 11, and both ends of the swing shaft 31 extend out of the mounting hole 11 and are connected to the convex pad 6 through the corresponding connecting rod 32.

[0033] Specifically, the lower end of the lifting rod 1 is provided with a mounting hole 11 which passes through the direction indicated by the Y-axis, the swing shaft 31 is extended along the direction indicated by the Y-axis, the connecting rod 32 is arranged along the direction indicated by the Z-axis, and the two ends of the swing shaft 31 are respectively connected by the corresponding upper ends of the connecting rod 32, and the lower end of the connecting rod 32 is connected to the upper surface of the convex pad 6.

[0034] In this embodiment, the convex pad 6 can be swung around the direction indicated by the axis of the swing shaft 31, that is, around the X-axis back and forth, to achieve grinding of the convex portion 61 of the convex pad 6.

[0035] In some other embodiments, the swing assembly 3 may include an elastic member, which can be vertically compressed. The vertical ends of the elastic member are respectively connected to the lifting rod 1 and the convex pad 6. When the concave pad 5 rotates, the convex pad 6 can compress the elastic member upward and reset it under the action of gravity, thereby achieving smooth grinding between the concave and convex pads.

[0036] like Figure 1 and Figure 3 As shown, optionally, the mounting hole 11 is an elongated hole extending axially along the lifting rod 1, and the swing shaft 31 is used to swing around a first axis in the mounting hole 11, and the first axis, the axis of the lifting rod 1 and the axis of the swing shaft 31 are perpendicular to each other.

[0037] Specifically, the long strip hole can be an oblong hole or an elliptical hole extending in the direction indicated by the Z axis, so that the swing shaft 31 can move in the mounting hole 11. The hanging rod 1 is arranged in the direction indicated by the Z axis, and the swing shaft 31 is arranged in the direction indicated by the Y axis. The first axis is perpendicular to the axis of the hanging rod 1 and the axis of the swing shaft 31, that is, the first axis is in the direction indicated by the X axis.

[0038] In this embodiment, based on the swing shaft 31 swinging back and forth around its own axis, the long strip mounting hole 11 is used to allow the swing shaft 31 to swing left and right around the Y axis, thereby achieving grinding of the concave and convex surface pad in the entire circumferential direction.

[0039] Optionally, there is a gap between the lower end surface of the hanging rod 1 and the convex pad 6 .

[0040] In this embodiment, the gap size between the lower end surface of the lifting rod 1 and the convex pad 6 can be flexibly set. It is necessary to ensure that the convex pad 6 will never contact the lower end surface of the lifting rod 1 during the entire process of up and down swinging, so that the grinding process can proceed smoothly.

[0041] like Figure 1-Figure 2 As shown, optionally, a key groove 62 is provided on one side of the convex pad 6 facing away from the convex portion 61, and a first positioning groove matching one end of the connecting rod 32 is provided at the bottom of the key groove 62, and the connecting rod 32 is inserted into the first positioning groove.

[0042] Specifically, the upper surface of the convex pad 6 is provided with a long keyway 62 penetrating along the Y direction, and the convex pad 6 can be connected to related parts through the keyway 62 and the spline. The first positioning groove can be cylindrical.

[0043] In this embodiment, the lower end of the connecting rod 32 is inserted into the first positioning groove to realize the positioning and assembly of the convex pad 6 and the swing assembly 3. Moreover, after the grinding is completed, when the convex pad 6 is installed on other parts, the first positioning groove is located in the key groove 62 and can be blocked by the spline, which will not affect the aesthetics of the convex pad 6.

[0044] like Figure 2 As shown, optionally, the swing assembly 3 also includes a fastener, and first connecting holes 311 are respectively provided at both ends of the swing shaft 31, and a second connecting hole 321 corresponding to the first connecting hole 311 is provided inside the connecting rod 32, and the fastener is used to pass through the first connecting hole 311, the second connecting hole 321 and the convex pad 6 in sequence.

[0045] Specifically, the fasteners may be pins or bolts. Both ends of the swing shaft 31 are provided with first connection holes 311 penetrating along the direction indicated by the Z axis, and the connecting rod 32 is provided with a second connection hole 321 along the direction indicated by the Z axis.

[0046] In this embodiment, a fastener is used to pass through the first connection hole 311, the second connection hole 321 and the convex pad 6 to achieve fixed installation between the convex pad 6 and the swing assembly 3, and the installation method is simple and convenient.

[0047] In some embodiments, the swing shaft 31 is clamped and fixed to the connecting rod 32 , and the connecting rod 32 is clamped and fixed to the convex pad 6 .

[0048] like Figure 1-Figure 3 As shown, optionally, the grinding device further includes a fixing plate 4 , wherein the fixing plate 4 is mounted on the rotating worktable 2 , and the fixing plate 4 is used to fix the concave pad 5 .

[0049] In this embodiment, the fixing plate 4 can be integrally formed with the rotating worktable 2, and the concave pad 5 can be fixed on the rotating worktable 2 by using the fixing plate 4 to achieve clamping and fixation of the concave pad 5. The fixing plate 4 can be made of a material with higher strength, and the concave pad 5 can be repeatedly disassembled and assembled thereon without damaging the rotating worktable 2.

[0050] like Figure 2-Figure 3 As shown, optionally, a positioning protrusion 41 is provided on the fixing plate 4 , and a second positioning groove 52 matched with the positioning protrusion 41 is provided on a side of the concave pad 5 facing away from the concave portion 51 , and the positioning protrusion 41 is used to be inserted into the second positioning groove 52 .

[0051] In this embodiment, a positioning protrusion 41 is provided on the upper surface of the fixed plate 4, and a second positioning groove 52 is provided on the lower surface of the concave pad 5. The positioning protrusion 41 can be cylindrical, and the second positioning groove 52 is also cylindrical.
