[0008] Further, a sleeve is rotatably inserted in the connecting seat between the pair of slide rods, one end of the sleeve extends to the outside, a first screw rod is threadedly connected in the sleeve, and one end of the first screw rod is fixedly connected with one side of the first clamping block.

[0009] The beneficial effect of the above further scheme is that the sleeve in the connecting seat is threadedly connected with the first screw rod, and when the sleeve is rotated, the first screw rod drives the first clamping block to move along the slide rod, thereby realizing clamping or loosening operation on one side of the tool.

[0010] Further, the inner top end of the connecting seat is rotationally connected with a first worm, and a first worm wheel is sleeved on the sleeve on the side close to the first worm.

[0011] The beneficial effect of the above further scheme is that the first worm in the connecting seat is in meshing engagement with the first worm wheel, and rotation of the first worm can drive the first worm wheel to rotate, thereby driving the sleeve to rotate.

[0012] Further, the upper end of the connecting plate is rotationally connected with a first hand wheel on one side, and the bottom end of the first hand wheel is connected with the top end of the first worm.

[0013] The beneficial effect of the above further scheme is that the first hand wheel on the upper end of the connecting plate is connected with the first worm, so that the operator can conveniently control the rotation of the first worm by rotating the first hand wheel, thereby adjusting the position of the first clamping block, and the operation is more convenient, and the work efficiency is improved.

[0034] Specifically, the working principle of the numerical control lathe tool clamping device is as follows: in use, the user installs the mounting frame 100 on the numerical control lathe at a suitable position through bolts, the operator rotates the first hand wheel 10103 at the upper end of the connecting plate 10102, the first hand wheel 10103 drives the first worm 10107 connected thereto to rotate. The first worm 10107 and the first worm wheel 10109 are in meshing engagement, thereby driving the first worm wheel 10109 to rotate. The first worm wheel 10109 is sleeved on the sleeve 10106, thereby driving the sleeve 10106 to rotate. Since the sleeve 10106 is internally threadedly connected with the first screw rod 10108, and the first screw rod 10108 is fixedly connected at one end with the first clamping block 10105, when the sleeve 10106 rotates, the first screw rod 10108 drives the first clamping block 10105 to move along the slide rod 10104.

After the movable frame 10203 is adjusted to a suitable vertical position, the top end of the tool is clamped. Combined with the clamping from the side by the first clamping block 10105 and the abutting block 104, the tool is stably clamped, thereby meeting the machining requirements of the numerical control lathe.
