Detailed ways

In order to make the utility model more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

Example

As shown in Figure 1-2, the schematic structural diagram of the cylindrical workpiece clamping device provided by the utility model includes a base 1, a guide rail 2 is provided on the base 1, and a first sheet clamp support 7, a second The second clip support 4, the first clip support 7, and the second clip support 4 are respectively provided with the first clip 6 and the second clip 5, and the first clip support 7 is fixedly connected with the guide rail 2 , the second clip support 4 adopts a semi-closed structure embedded in the guide rail 2, so that it can move in the direction of the guide rail 2. The first sheet clamp support 7 is connected with the second sheet clamp support 4 by the leading screw 3 passing through the first sheet clamp support 7 and the second sheet clamp support 4. The outside of the leading screw 3 is provided with threads, and the leading screw 3 and the second clip support 4 are connected by threads. The leading screw 3 is fixed to the base 1 through the leading screw support 9 . The first sheet holder 6 and the second sheet holder 5 are V-shaped, the openings of the first sheet holder 6 and the second sheet holder 5 are arranged oppositely, and the vertices of the first sheet holder 6 and the second sheet holder 5 are located on the same horizontal line, When the first sheet holder 6 and the second sheet holder 5 are close, the openings of the two form a diamond-shaped hole. The first sheet holder 6 and the second sheet holder 5 are mutually nested, that is, the first sheet holder 6 can be inserted into the second sheet holder 5, so as to be suitable for cylindrical workpieces of different sizes. One end of the lead screw 3 is provided with a handle 8 .

When the utility model is in use, the handle 8 is rotated to drive the lead screw 3 to rotate, and the second clip support 4 arranged at one end of the lead screw 3 drives the second clip 5 to move in the direction of the guide rail 2, so that the second clip 5 Close to the first sheet clamp 6; Cylindrical workpiece 10 is placed in the diamond-shaped hole between the first sheet clamp 6 and the second sheet clamp 5 (as shown in Figure 3), and the handle 8 is rotated to make the first sheet clamp 6.
