[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0022] See attached Figure 1As shown, a processing fixture for a cover plate in this embodiment includes a fixed plate 2, which is arranged on a workbench 1 of a numerically controlled machine tool, and the fixed plate 2 is fixed by the workbench 1. The fixed plate 2 is arranged above the workbench 1 and is arranged parallel to the workbench 1. The fixed plate 2 has a certain thickness in the Z-axis direction, and a groove 21 is arranged in the thickness direction. The driving mechanism 3 is arranged in the groove 21. The clamping member of the clamping mechanism is arranged above the fixed plate 2 and is arranged close to the edge of the fixed plate 2. The cover plate 7 to be processed is placed in the middle position above the fixed plate 2, and the clamping member clamps and fixes the cover plate 7.

[0023] See attached Figure 1 and attached Figure 2 As shown, in some embodiments, the clamping mechanism includes an X-axis clamping mechanism 4 and a Y-axis clamping mechanism 5. The X-axis clamping mechanism 4 clamps and fixes the cover plate 7 in the X-axis direction, and the Y-axis clamping mechanism 5 clamps and fixes the cover plate 7 in the Y-axis direction. A group of driving mechanisms 3 is provided, and a group of driving mechanisms 3 can simultaneously drive the X-axis clamping mechanism 4 and the Y-axis clamping mechanism 5. By providing the X-axis clamping mechanism 4 and the Y-axis clamping mechanism 5, the cover plate 7 is fixed on a plane.

[0024] In some embodiments, the driving mechanism 3 includes a driving cylinder 31 and a driving shaft 32. The driving cylinder 31 can drive the driving shaft 32 to extend and retract in the X-axis direction. The driving cylinder 31 is located on one side of the fixed plate 2. The driving shaft 32 connected to the driving cylinder 31 penetrates the side wall of the fixed plate 2 into the groove 21, and then penetrates the side wall of the other side of the fixed plate 2.

[0025] The X-axis clamping mechanism 4 includes a first X-axis clamping member 41 and a second X-axis clamping member 42. The second X-axis clamping member 42 is located on the side away from the driving cylinder 31 in the X-axis direction. The second X-axis clamping member 42 is detachably connected to the fixing plate 2. The first X-axis clamping member 41 is located on the side close to the driving cylinder 31 in the X-axis direction. The first X-axis clamping member 41 is connected to the driving shaft 32. The driving shaft 32 can drive the first X-axis clamping member 41 to move closer to or away from the second X-axis clamping member 42 during the extension and retraction process, thereby clamping the cover plate 7 in the X-axis direction.

[0026] In some embodiments, a waist-shaped hole 421 is provided on the second clamping member 42, and the length direction of the waist-shaped hole 421 is the X-axis direction. A plurality of connection holes are provided at corresponding positions of the fixed plate 2. The waist-shaped hole 421 and the connection holes at different positions are connected by screws or bolts, thereby changing the connection position of the second clamping member 42 and the fixed plate 2, and changing the distance between the first clamping member 41 and the second clamping member 42 in the X-axis direction, so that the X-axis clamping mechanism 4 can adapt to cover plates 7 of different lengths. In addition, the ratio of the clamping range of the X-axis clamping mechanism 4 to the clamping range of the Y-axis clamping mechanism 6 is changed, so that the cover plates 7 of different length-width ratios can be adapted, and the application range of the processing fixture is increased.

[0027] In some embodiments, the Y-axis clamping mechanism 6 includes two sets of clamping components arranged in mirror images, and the two sets of clamping components are moved closer to or away from each other under the action of the driving cylinder 31, thereby clamping the cover plate 7 in the Y-axis direction. Specifically, the clamping component includes a fixing block 52 arranged in the groove 21, and a through hole in the Y-axis direction is arranged on the fixing block 52. The guide rod 53 passes through the through hole and is connected to the side wall of the groove 21, and the fixing block 52 can move in the Y-axis direction along the guide rod 53.

[0028] In some embodiments, the driving mechanism 3 further includes a first hinge 33, and the first hinge 33 is fixedly connected to the driving shaft 32. Specifically, a first through hole is provided on the first hinge 33, and the driving shaft 32 passes through the first through hole, and a limit rod 35 is provided to penetrate the first hinge 33 and the driving shaft 32 to prevent the first hinge 33 from sliding along the driving shaft 32. The first hinge 33 is symmetrically arranged with the driving shaft 32 as the symmetry axis, and both ends are respectively connected to the Y-axis clamping assembly.

[0029] In some embodiments, the driving mechanism 3 further includes a second hinge 34, one end of which is hinged to the end of the first hinge 33, and the other end is hinged to the hinge block 54. With the two ends of the second hinge 34 respectively hinged to the first hinge 33 and the hinge block 54, when the first hinge 33 moves in the X-axis direction along with the driving shaft 32, the fixing block 52 can move in the Y-axis direction along the guide rod 53.

[0030] In some embodiments, a Y-axis clamp 51 is disposed above the fixed block 52, and the Y-axis clamp 51 is fixedly connected to the fixed block 52. When the fixed block 52 moves in the Y-axis direction, the Y-axis clamp 51 is driven to move. The Y-axis clamp assembly is symmetrically arranged on the plane where the center line of the drive shaft 32 is located, and the two groups of Y-axis clamps 51 are close to or away from each other to clamp and fix the cover plate 7 on the Y-axis.

[0031] In some embodiments, two fixing blocks 52 are provided, which are provided close to both ends of the Y-axis clamping member 51 to ensure the stability of the movement of the fixing blocks 52 in the Y-axis direction. A hinge block 54 is provided between the two fixing blocks 52, and the hinge block 54 is used to connect with the driving mechanism 3 to drive the Y-axis clamping mechanism 5 to move.

[0032] In the present application, when the driving cylinder 31 drives the first clamping member 41 to approach the second clamping member 42, the cover plate 7 is clamped in the X-axis direction. At the same time, the first hinge 33 moves toward the second clamping member under the action of the driving shaft 32, and drives the Y-axis clamping components to approach each other through the second hinge 34 and the hinge block 54, thereby fixing the cover plate 7 in the Y-axis direction. Therefore, the present application uses a driving cylinder 31 to simultaneously enable the X-axis clamping mechanism 4 and the Y-axis clamping mechanism 5 to clamp the cover plate 7, thereby improving work efficiency.

[0033] In some embodiments, a buffer 6 is provided between the first hinge 33 and the side wall of the groove 21 . The buffer 6 is elastic and prevents the first hinge 33 from colliding with the inner wall of the groove 21 and damaging the first hinge 33 and the side wall of the groove 21 .

[0034] In the present application, the groove 21 provided on the fixing plate 2 may also be a through groove from top to bottom, and the present application does not limit this, as long as a cavity that can accommodate the first hinge 33, the second hinge 34, and the hinge block 54 is left.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
