Detailed Description

The following detailed description of the embodiments of the present invention will be provided with reference to the accompanying drawings, but the present invention is not limited to these embodiments, and any modifications or substitutions in the basic spirit of the embodiments will still fall within the scope of the present invention as claimed in the appended claims.

Example 1: as shown in fig. 1, 2 and 3, the jig for clamping a cylindrical workpiece comprises a rectangular main body 1 with an inner cavity, wherein a fixed plate 2 and a movable clamping plate 3 with a moving mechanism are vertically and oppositely arranged in the inner cavity of the rectangular main body 1; the equal vertical multichannel matched with slot 4 that is provided with of the relative terminal surface of fixed plate 2 and movable clamp plate 3 on the slot 4 of fixed plate 2 and perpendicular fixed plate 2 is provided with direction automatic positioning piece 5 be provided with on the movable clamp plate 3 with direction automatic positioning piece 5 complex recess 6.

The moving mechanism comprises a screw rod 7, the screw rod 7 sequentially penetrates through the fixed plate 2 and the moving clamp plate 3, and two ends of the screw rod 7 are connected with two sides of the rectangular main body 1 through bearings 8 and bearing pressing plates 9; the movable clamping plate 3 is matched with the screw rod 7 through threads.

In order to adapt to workpieces with different lengths, each groove 4 on the fixing plate 2 is provided with an automatic direction positioning block 5, and the automatic direction positioning blocks 5 are positioned on the same or non-same horizontal line.

As shown in fig. 4, in the utility model discloses, direction automatic positioning piece 5 includes the column body, the one end of column body penetrates perpendicularly in fixed plate 2 the other end of column body is provided with L shape platform 10.

Further, a limit screw 11 is arranged at the end of the columnar body penetrating through the end of the fixing plate 2, a spring 12 is arranged on the limit screw 11, one end of the spring 12 extends into the columnar body, and the other end of the spring is supported on the inner side of the rectangular main body 1.

In order to limit the up-and-down movement of the movable clamping plate and simultaneously enable the movable clamping plate to automatically slide back and forth in the inner cavity of the rectangular main body, a pressing strip A13 and a pressing strip B14 are horizontally arranged in the inner cavity of the rectangular main body 1; and two ends of the fixed plate 2 and the movable clamping plate 3 are respectively provided with a limiting groove 15 matched with the pressing strip A13 and the pressing strip B14.
