[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to Figure 1-3 The shown device is a machine tool manipulator moving device, including a support column 1, a fixed seat 2, a linear guide 3, a screw 4, a slider 5, an electric push rod 6 and a pneumatic splint 8. The bottom end of the electric push rod 6 is fixedly connected to a pressure plate 7, the air pump is located on the upper side of the slider 5, and the pneumatic splint 8 is located on the bottom side of the pressure plate 7. The above structure constitutes a manipulator moving structure, which can grab materials and move. A moving block 9 is slidably connected to one side of the linear guide 3. An adjusting rod 10 is threadedly connected to the moving block 9. The bottom end of the adjusting rod 10 is rotatably connected to an auxiliary block 11 through a bearing. A slot 12 is provided in the auxiliary block 11. A rod 13 is movably inserted in the slot 12. One end of the rod 13 is fixedly connected to a triangular column 14. A connecting plate 15 is fixedly connected to the insertion rod 13, and a spring 17 is in contact with one side of the connecting plate 15. A distance sensor 16 is fixedly connected to one side of the auxiliary block 11. The distance sensor 16 corresponds to the connecting plate 15. By setting the auxiliary block 11 on one side of the pressure plate 7, and when the electric push rod 6 is extended, the pressure plate 7 will squeeze the triangular column 14 and make the triangular column 14 move toward the side of the auxiliary block 11. When the pressure plate 7 squeezes the inclined surface of the triangular column 14 and the angle between the triangular column 14, the monitoring value of the distance sensor 16 changes with a certain regularity. At this time, the spring 17 contracts and causes the distance between the connecting plate 15 and the distance sensor 16 to change, thereby providing monitoring.

[0020] Among them, the pad 18 is fixedly connected to one side of the connecting plate 15, the auxiliary block 11 is in contact with the connecting plate 15, and the pad 18 is made of rubber material. By setting the pad 18, protection is provided to prevent the connecting plate 15 from contacting the distance sensor 16.

[0021] The distance sensor 16 is connected to the alarm 19 via a wire. The alarm 19 is fixedly connected to one side of the auxiliary block 11. By setting the alarm 19, an alarm can be provided when the pressure plate 7 does not contact the auxiliary block 11 according to a certain rule.

[0022] Among them, the fixed seat 2 corresponds to the end of the positioning rod 21, the positioning rod 21 is threadedly connected to the protrusion, and the protrusion is fixedly connected to one side of the moving block 9. By setting the positioning rod 21, the position of the moving block 9 can be adjusted to adapt to the moving path of the manipulator structure.

[0023] Among them, the upper end of the fixed seat 2 is fixedly connected to the buffer pad 22, the buffer pad 22 is in contact with the end of the positioning rod 21, and the buffer pad 22 is made of rubber material. By setting the buffer pad 22, the friction force can be increased and the stability of the moving block 9 when it is limited can be improved.

[0024] The upper end of the auxiliary block 11 is fixedly connected to the auxiliary rod 20 , and the auxiliary rod 20 is movably plugged into one side of the fixing seat 2 . By providing the auxiliary rod 20 , the stability of the auxiliary block 11 and the triangular column 14 contacting the pressure plate 7 can be increased.

[0025] Working principle: In the process of moving materials, it is necessary to first set the moving path of the manipulator structure on the linear guide rail 3 and the screw 4, rotate the adjustment rod 10, and move the auxiliary block 11 downward so that the auxiliary block 11 is on the side when the manipulator releases the material, and then use the positioning rod 21 to connect the buffer pad 22, so that the pressure plate 7 can contact and squeeze the triangular column 14 when moving, so that the insertion rod 13 shrinks into the auxiliary block 11, and drives the connecting plate 15 close to the distance sensor 16, and the distance sensor 16 monitors and transmits data.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention.
