Detailed Description

In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

referring to fig. 1-3, a numerical control machine tool fixture with a plurality of fixed points and convenient installation comprises a bottom case 1, a double-shaft motor 2 is fixed on the inner wall of the bottom case 1, a screw rod one 3 is fixed on each of two output ends of the double-shaft motor 2, a worm wheel 4 is fixed on the outer portion of the screw rod one 3 on the left side, screw rods two 11 are rotatably connected on the inner walls of two sides of the bottom case 1, a worm 8 is fixed on one end of each screw rod two 11 close to each other, the bottom of the worm 8 is in meshing transmission with the worm wheel 4, two sliding chutes one are arranged on the top of the bottom case 1, two moving plates 5 are sleeved in each sliding chute one, the moving plates 5 are respectively sleeved on the outer portions of the screw rods one 3 and the screw rods two 11, a clamping plate one 6 is fixed on the top of each clamping plate one 6, a sliding chute two 7 is arranged on one side of the double-shaft motor 2, and a pulley 9 is sleeved in the sliding chute two 7, a second clamping plate 10 is fixed on one side of the pulley 9.

In this embodiment, the screw turns of the first screws 3 are opposite to the screw turns of the second screws 11, and the opposite screws can make the two moving plates 5 approach each other in the same direction.

In this embodiment, a plurality of springs 12 are fixed on one side of the four second clamping plates 10 relative to the dual-axis motor 2, and anti-slip plates 13 are fixed on the springs 12, wherein the anti-slip plates 13 increase the friction force between the anti-slip plates 13 and a workpiece.

In this embodiment, anti-skidding line has all been seted up for one side of biax motor 2 to four antiskid ribbed tile 13, and anti-skidding line increases frictional force.

In this embodiment, the first two screws 3 are rotatably connected with the first bottom case 1, and the first screws are supported by the first bottom case 1.
