Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The invention provides a dragging, butting and adjusting device for a forming cylinder body of a 3D printer, which comprises a square table-shaped support 2 with a rectangular or square hole at the center of the top, a forming cylinder 3 is sleeved in the support 2 at a position corresponding to the hole at the top, the support 2 and the forming cylinder 3 are both positioned on the ground, the forming cylinder 3 is of a cylinder body structure, a rectangular or square interface is arranged at the top, a plurality of dragging and adjusting mechanisms 4 are arranged on the support 2 at intervals along the circumference of the hole, the dragging and adjusting mechanisms 4 are distributed in two directions X, Y which are perpendicular to each other, a forming chamber 1 butted with the forming cylinder 3 is jointly supported above the dragging and adjusting mechanisms 4, the forming chamber 1 is of a box body structure, an interface corresponding to the forming cylinder 3 is arranged at the bottom, and the interface penetrates through the rectangular or square hole at the top of the support 2 to be butted with the forming cylinder 3.
As shown in figure 3, the dragging and adjusting mechanism 4 comprises a zigzag dragging frame 4-1, a boss 4-5 which is propped against the dragging frame 4-1 extends downwards from the bottom end of the forming chamber 1, a guide table 4-6 is fixed on one side of the boss 4-5 on the dragging frame 4-1 at intervals, a horizontal guide hole 4-7 is formed in the guide table 4-6, a pull rod 4-2 which is positioned in the X or Y direction is coaxially arranged in the guide hole 4-7 in a sliding manner, one end of the pull rod 4-2 is fixedly connected with the boss 4-5, and the other end of the pull rod 4-2 is fixedly connected with a driving device 4-3, namely an air cylinder or an electric cylinder. The top end of the dragging frame 4-1 is provided with a first long hole 4-8 which is in the same direction with the upper pull rod 4-2, and a first bolt 4-4 which penetrates the boss 4-5 upwards and is in threaded connection with the boss is arranged in the first long hole 4-8.
