Detailed Description

In order to make the technical solutions of the present invention clearer and clearer for those skilled in the art, the present invention will be described in further detail with reference to the following embodiments and drawings, but the embodiments of the present invention are not limited thereto.

As shown in fig. 1-4, the present embodiment provides a manipulator for a numerical control machine tool, including template 1, both sides inside template 1 are all symmetrically installed with first gear 2, and first gear 2 all rotates with template 1 to be connected, all fixedly installed with first grip block 3 on first gear 2, and the bottom of the first grip block 3 inboard all is fixed with stopper 4, spout 5 has all been seted up to the inboard of first grip block 3, and the inside of spout 5 all is provided with slider 7, and the both sides of slider 7 all are fixed with reset spring 6, reset spring 6 all is fixed with the inboard fixed connection of spout 5, install second gear 8 between slider 7, and second gear 8 all rotates with slider 7 to be connected, all fixedly installed with second grip block 9 on second gear 8, the top fixed mounting of template 351 has mount 11, and the bottom fixed mounting of mount 11 diaphragm has telescopic cylinder 12, rack 13 is installed to the output of telescopic cylinder 12, rack 13 all meshes with first gear 2, second gear 8.

In this embodiment, as shown in fig. 1, the rubber blocks 10 are fixedly mounted on the inner sides of the second clamping plates 9, and the anti-slip grooves are formed on the outer sides of the rubber blocks 10, so that the rubber blocks 10 can deform in the clamping process and are attached to the surface of the workpiece, thereby improving the clamping stability.

In this embodiment, as shown in fig. 1, the shape of the limiting block 4 is a right trapezoid, and the bottom surface of the limiting block 4 is at the same level as the bottom end of the first clamping plate 3, so that the workpiece support can be clamped up conveniently in the use process of the device.

In the present embodiment, as shown in fig. 1, the width of the bottom of the rack 13 is greater than that of the top, so that the second seesaw 9 can be tilted when the first clamping plate 3 is in the vertical state with the -shaped plate 1, and the workpiece is prevented from being pushed upwards.

In the present embodiment, as shown in fig. 1, a fixed block is attached to the bottom of the rack 13, and the rising length of the rack 13 can be limited.
