Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

Referring to fig. 1-3, a clamp for a numerical control machine tool comprises a table 1, two movable plates 2 disposed at both sides of the table 1 in a width direction and capable of moving in opposite or opposite directions, and a first clamping plate 8 and a second clamping plate 10 for clamping,

the top of the opposite side surfaces of the two moving plates 2 is fixedly connected with three fixed strips 6, and the slots 9 formed in the three fixed strips 6 are movably inserted with movable strips 7;

the end parts of the movable strips 7 in the middle are fixedly provided with a first clamping plate 8, the openings at the end parts of the two movable strips 7 on the two sides are provided with shaft rods 12, the rotating sleeve 11 is movably sleeved on the shaft rods 12, and the second clamping plate 10 is fixedly arranged on the rotating sleeve 11.

As shown in fig. 3, a spring 15 is connected between one end of the movable bar 7 inserted into the fixed bar 6 and the end groove wall of the slot 9.

By adopting the scheme, when the movable strips 7 on the two sides move in the slots 9 in the corresponding fixed strips 6, the spring 15 can be compressed, and the second clamping plate 10 can be tightly abutted to a workpiece through the movable strips 7 by utilizing the elastic force generated by the spring 15.
