[0002] When grinding the surface of a workpiece such as a metal sheet or foil, it is necessary to avoid deformation or wrinkling of the workpiece material to avoid affecting the flatness of the workpiece. Therefore, the workpiece needs to be fixed on the processing table before grinding. In the prior art, a clamping plate or other structure is generally used to clamp and fix the workpiece, but the clamping part of the clamping plate will be blocked and cannot be ground. After completing one grinding, the direction of the workpiece can only be manually adjusted, and then a second grinding is performed to grind the remaining part of the workpiece. This clamping structure not only increases the workload and reduces work efficiency, but also in the process of adjusting the direction of the workpiece, it may also cause the position of the workpiece on the processing table to deviate, resulting in inadequate grinding, affecting the grinding quality of the workpiece.

DETAILED DESCRIPTION

[0021] The embodiments of the present invention are described in detail below. Figures 1 to 4 The present invention provides a grinding device and a clamping mechanism thereof. The clamping mechanism includes a housing 100, a positioning base 200, a first clamping assembly 300, and a second clamping assembly 400. The positioning base 200 is installed within the housing 100 and is used to position and place a workpiece. When grinding a workpiece such as a metal sheet or foil, the workpiece can be positioned and placed on the positioning base 200. The first clamping assembly 300 and the second clamping assembly 400 can alternately press the workpiece toward the positioning base 200 at different positions to press the workpiece against the positioning base 200. At the beginning of grinding, the first clamping assembly 300 can clamp the workpiece, and the grinding head 500 can begin grinding other parts, that is, parts not blocked by the first clamping assembly 300. Subsequently, the second clamping assembly 400 clamps the workpiece at other positions. The first clamping assembly 300 is then released, and the grinding head 500 begins grinding the parts initially clamped by the first clamping assembly 300, thereby completing the grinding of the entire workpiece surface. This clamping mechanism uses the first clamping component 300 and the second clamping component 400 to alternately clamp the workpiece, which not only facilitates the grinding of the workpiece, but also during the entire grinding process, the workpiece is always pressed on the positioning base 200 and will not shift relative to the positioning base 200, thereby ensuring that the entire workpiece surface can be ground and avoiding the situation of incomplete grinding.

[0022] Further, refer to Figure 1 The housing 100 is turned over and connected to the dust cover 120. The internal structure of the dust cover 120 after removal is as follows: Figure 2As shown. The dust cover 120 is connected to the housing 100 via a hinge or other structure and can be flipped up and down to open and close. The dust cover 120 can isolate dust and debris generated during the grinding process, as well as metal sparks and metal chips generated during operation. Furthermore, a non-slip pad 110 is mounted on the bottom of the housing 100. The upper end of the non-slip pad 110 is made of metal and the lower end is made of plastic, ensuring that the entire grinding device is non-slip.

[0023] Further, refer to Figure 2 and Figure 3 The first clamping assembly 300 includes a first driving member 310 and a first pressure plate 320. The first driving member 310 is installed in the housing 100. The first pressure plate 320 is connected to the output end of the first driving member 310 and is rotatably connected to the positioning base 200. The first driving member 310 can drive the first pressure plate 320 to rotate relative to the positioning base 200 to clamp or loosen the workpiece. The first pressure plate 320 is a rubber pressure plate to avoid damaging the surface of the workpiece during the process of clamping the workpiece. The first driving member 310 can be directly connected to the first pressure plate 320 for driving, or it can be driven by gear transmission or other methods. The first driving member 310 can adopt a structure such as a rotating motor. Further, referring to Figure 2 and Figure 4 The second clamping assembly 400 includes a second driving member 410 and a second pressure plate 420. The second driving member 410 is installed in the housing 100. The second pressure plate 420 is connected to the output end of the second driving member 410. The second driving member 410 can drive the second pressure plate 420 to move toward or away from the positioning base 200 to compress or loosen the workpiece. The second driving member 410 can be a structure such as an electric cylinder, and the second pressure plate 420 is a rubber pressure plate to avoid damaging the surface of the workpiece during the compression process. At the beginning of grinding, the first driving member 310 drives the first pressure plate 320 to rotate, pressing the workpiece against the positioning base 200, while the second driving member 410 drives the second pressure plate 420 away from the positioning base 200 to avoid affecting the grinding operation of the grinding head 500. After the grinding of other parts is completed, the second driving member 410 drives the second pressing plate 420 to press the workpiece toward the positioning base 200. After pressing, the first driving member 310 drives the first pressing plate 320 to rotate away from the workpiece, and the grinding head 500 can grind the position initially pressed by the first pressing plate 320. Of course, the grinding head 500 in this solution can refer to existing technologies, such as grinding wheels, wire brushes, etc., and will not be described in detail here.

[0024] Furthermore, since the grinding head 500 requires sufficient installation space and moving space, in order to better prevent the second clamping assembly 400 from affecting the grinding work of the grinding head 500, the second clamping assembly 400 also includes a third driving member and a first truss 430. The third driving member is installed in the housing 100 and can adopt a structure such as a rotating motor. The first truss 430 is connected to the output end of the third driving member, and the second driving member 410 is installed on the first truss 430. The third driving member can drive the first truss 430 to rotate relative to the housing 100, thereby driving the second driving member 410 and the second pressure plate 420 to rotate relative to the housing 100. At the beginning of grinding, the third driving member drives the first truss 430 to rotate relative to the housing 100, as shown in FIG. Figure 2 As shown, the second driving member 410 and the second pressing plate 420 can be made parallel to the positioning base 200, which leaves sufficient room for the grinding head 500 to move. After grinding of other parts is completed, the third driving member drives the first truss 430 to rotate, so that the second pressing plate 420 is once again oriented toward the positioning base 200. At this time, the second driving member 410 can be activated, and the second driving member 410 drives the second pressing plate 420 toward the positioning base 200 to press the workpiece, and then the first pressing plate 320 can be released.

[0025] Furthermore, the second clamping assembly 400 further includes a fourth driver 440 and a second truss 450. The fourth driver 440 is mounted on the housing 100 and can be implemented as an electric cylinder or other structure. The second truss 450 is connected to the output end of the fourth driver 440 and is movably connected to the housing 100. The third driver is mounted within the second truss 450. The fourth driver 440 is capable of driving the second truss 450 to move relative to the housing 100, thereby driving the third driver, the first truss 430, the second driver 410, and the second pressure plate 420 to move relative to the housing 100. For workpieces of different sizes, the first pressing plate 320 rotatably connected to the positioning base 200 can press the workpiece against the positioning base 200, and the fourth driving member 440 can drive the second truss 450 to move relative to the housing 100 according to the specific size of the workpiece, so that the third driving member, the first truss 430, the second driving member 410 and the second pressing plate 420 can move in a direction parallel to the surface of the workpiece to be polished, so that the second pressing plate 420 can move to a position matching the size of the workpiece, and then move toward the workpiece under the drive of the second driving member 410, so that it can accurately press against the workpiece. Of course, it should be noted that in Figure 4 In the figure, the third driving member is installed inside the second truss 450 and is therefore not shown in the figure. It should also be noted that although the first truss 430 and the second truss 450 in the figure are both square columns, the square column parts of the first truss 430 and the second truss 450 are not socketed, so it does not affect the rotational coordination between the two.
