Problems solved by technology
[0002] Generally, the hand wheel of the machine tool is designed as a clutch. Pushing the hand wheel to the machine tool can buckle the tool holder transmission rod, so that the tool holder can be driven to move by turning the hand wheel, and the hand wheel can be detached from the tool holder by pulling out the hand wheel. The transmission rod, so that the tool holder will not move with the handwheel when the machine control moves, but in the actual machine tool operation, the operator will not pay much attention to whether the hand wheel has completely disengaged from the tool holder transmission rod, and suddenly uses the machine control Moving the knife holder will drive the hand wheel to rotate together, which is easy to injure people. This is a common problem that has not been well solved.

Embodiment Construction
[0011] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0012] Such as figure 1 As shown, a machine tool handwheel of the present invention includes a tripod 1 connected to the machine tool and a slot ring 2 fixedly connected to the tripod 1. The arc-shaped side of the slot ring 2 is provided with a slot, and in the slot Set a rotating rim 3 that can rotate around the groove ring 2, set a "U"-shaped notch on one side of the groove ring 2, set a rotating handle 4 on the side of the rotating rim 3, and rotate the handle 4 and rotate The joint of the rim 3 is provided with a sliding groove 5 for the rotating handle 4 to slide into the "U"-shaped gap, and the rotating handle 4 is movably connected with the sliding groove 5 .
[0013] The sides of the "U"-shaped notch are arc-shaped.
[0014] The turning handle 4 is made of magnetic material.

The invention discloses a machine tool hand wheel which comprises a triangular support connected with a machine tool and a clamping groove ring fixedly connected with the triangular support. A clamping groove is formed in the arc side face of the clamping groove ring. A rotary rim ring capable of rotating around the clamping groove ring is arranged in the clamping groove. A U-type notch is formed in the portion of the side face of the clamping groove ring. A rotary handle is arranged on the side face of the rotary rim ring. A sliding groove allowing the rotary handle to slide to the U-type notch is formed in the connecting portion of the rotary handle and the rotary rim ring. The rotary handle is movably connected with the sliding groove. Compared with the prior art, the rotary handle of the machine tool hand wheel can be rotationally inserted in the U-type notch, so that the clamping groove ring and a tool rest transmission rod are driven to rotate simultaneously, a tool rest is adjusted, when rotation is not needed, the rotary handle can be pulled out, the rotary handle can not be rotated when the clamping groove ring is driven to rotate by tool rest mechanical control feeding movement, and the rotary handle is prevented from rotating along with machine tool rest feeding operation and hurting people.
