The chuck 4032 is fixed on the left internal thread of the pull rod 4041 through the right external thread of the chuck, and when the air cylinder 404 moves rightwards, the pull rod 4041 is driven to move in the direction far away from the chuck 4032, so that the chuck 4032 is loosened; when the air cylinder 404 moves leftwards, the pull rod 4041 is driven to move towards the chuck 4032, so that the chuck 4032 is tensioned; the structure has the advantages of higher product clamping speed and simpler and easier operation.
In another embodiment, an a-axis servo motor 4033 is provided on one side of the rotating platform 403. The air cylinder 404 is used for urging the movement, the terrain is not occupied, and the operation is convenient.
In another embodiment, the end of the bottom plate 401 on which the vertical plate 402 is erected is 2-3cm higher than the table surface of the bottom plate 401 below the chuck 4032. A certain working distance is reserved between the clamp 4032 and the bottom plate 401, so that the product can be conveniently clamped.
The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
