[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a quick-clamp structure is provided on the top of the base 20, and the quick-clamp structure includes a live edge 33, a driven column 36 and an active column 38. The live edge 33 is movably connected to the top of the base 20, the driven column 36 is rotatably connected to a side wall of the live edge 33, and the active column 38 is rotatably connected to a side wall of the fixed edge 21. The quick-clamp structure can clamp the engine connecting rod.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the thickness of the fixed edge 21 is consistent with the width of the base 20, the output end of the rotating motor 22 can pass through the fixed edge 21 and be connected to the active column 38, the height of the live edge 33 is consistent with the fixed edge 21, the driven column 36 and the active column 38 are on the same horizontal line, the driven column 36 is a small cylindrical shape between the ends, the slide groove 30 is a convex-shaped groove, the slide groove 30 can adapt to the size of the slider 31, the quick clamping structure also includes a first sliding roller 34, an anti-slip groove 37, an anti-slip block 39, a pair of rods 40 and a second sliding roller 41, the first sliding roller 34 is rotatably connected to the front wall surface of the live edge 33, the anti-slip groove 37 is opened on the wall surface of the driven column 36 facing the active column 38, the anti-slip block 39 is fixedly connected to the wall surface of the active column 38 facing the driven column 36, the pair of rods 40 is fixedly connected to the side wall surface of the fixed edge 21, and the second sliding roller 41 is rotatably connected to the wall surface of the pair of rods 40 , the first sliding roller 34 and the second sliding roller 41 are both cylindrical with the same height, the front wall surface of the live edge 33 is in the shape of an inclined plane, and the inclined plane of the live edge 33 is provided with a rectangular groove adapted to the first sliding roller 34, and the first sliding roller 34 is rotatably connected in the rectangular groove of the wall surface of the live edge 33, and the inclined plane angle of the live edge 33 is consistent with the inclined plane angle of the driven column 36, the cross section of the rod 40 is in the shape of a right triangle, and the inclined plane of the rod 40 is provided with a rectangular groove adapted to the second sliding roller 41, and the second sliding roller 41 is rotatably connected in the rectangular groove of the wall surface of the rod 40, and the inclined plane of the rod 40 and the inclined plane of the live edge 33 are symmetrical to each other, and the highest point of the inclined plane of the rod 40 is flush with the anti-slip block 39, and the side wall surface of the fixed edge 21 is fixedly connected with a bottom plate 42, and the rear wall surface of the live edge 33 is provided with an anti-blocking groove 35, and the bottom plate 42 is in the shape of an arc plate, and the side edge of the bottom plate 42 can pass through the anti-blocking groove 35;

[0029] During specific use, the workpiece to be clamped is inserted between the driven column 36 and the active column 38. At this time, the driven column 36 will be pushed by the workpiece. When the driven column 36 is pushed, the live edge 33 will also move. The slider 31 will move in the slide groove 30 due to the movement of the live edge 33. The tension spring 32 can pull the slider 31 toward the fixed edge 21. When the slider 31 is pulled, it drives the live edge 33 and the active column 38, thereby completing the fixation of the workpiece. When grinding the workpiece, the power of the rotating motor 22 is turned on, and the rotating motor 22 can drive the active column 38 to rotate. The active column 38 can drive the anti-slip block 39 and the workpiece to rotate at the same time when rotating, and the workpiece drives the driven column 36 to rotate when rotating.

[0030] In summary, by setting up a quick clamping structure, the workpiece can be quickly clamped on the top of the base 20, because the quick clamping structure clamps the workpiece on the top of the base 20 through the opening formed by the live edge 33 and the inclined wall of the rod 40, combined with the slider 31 that can move and automatically tighten. This clamping process only requires the workpiece to be inserted between the driven column 36 and the anti-slip block 39 to be completed, so compared with the prior art, workers can use this solution more easily and quickly.

The other end of the tension spring 32 is fixedly connected to the side wall of the slider 31. The live edge 33 is fixedly connected to the top of the slider 31.

[0032] In specific use, the live edge 33 and the slide block 31 can move according to the size of the workpiece;

[0033] In summary, by providing the quick clamping structure, workpieces of different sizes can also be adapted, because the quick clamping structure can adapt itself to the size of the workpiece through the movable live edge 33, thereby increasing the application range of the device.

[0034] A grinding machine, not shown in the figure, is used with the bottom of a base 20 fixed to the grinding machine. By setting a positioning fixture assembly, the work efficiency can be higher and the working time can be shorter when processing a workpiece.

[0035] Working principle: Insert the workpiece to be clamped between the driven column 36 and the active column 38. At this time, the driven column 36 will be pushed by the workpiece. When the driven column 36 is pushed, the live edge 33 will also move. The slider 31 will move in the slide groove 30 due to the movement of the live edge 33. The tension spring 32 can pull the slider 31 toward the fixed edge 21. When the slider 31 is pulled, it drives the live edge 33 and the active column 38, thereby completing the fixation of the workpiece.
