Description

Technical Field

[0001] The invention relates to the technical field of leveling machines, and in particular to an upper leveling mechanism with a stable structure. Background Art

[0002] The leveling machine is used to level the plates, and the lower leveling mechanism of the leveling machine is usually set to a horizontal state. The upper leveling mechanism adjusts the upper movable plate to have a certain inclination according to demand, so that the distance between the upper and lower leveling mechanisms gradually decreases from the feed port side to the discharge port side. In the past, the upper movable plate was connected to the machine body through guide columns. Since the angle needs to be adjusted, the aperture of the guide hole is increased to leave a movable space between the guide column and the guide hole, and then the front and rear height of the upper movable plate is adjusted by four sets of screw lifts. After adjustment, there is still a gap between the guide column and the guide hole, which leads to poor stability of the upper movable plate and easy shaking during operation, so it needs to be improved.

[0013] The present invention will be further described below in conjunction with the accompanying drawings:

Position sensors 7 are respectively arranged on the left and right sides of the movable block 62 to detect the height position of the upper movable plate 3 in real time for adjustment, and the adjustment can be made on the control panel according to the actual situation. When the angle of the upper movable plate 3 is adjusted by the four groups of lifting drive devices 2, a movable gap is reserved between the front and rear sides of the upper movable plate 3 and the support column 11 for the upper movable plate 3 to flip forward and backward. During the flipping process of the upper movable plate 3, the four first top blocks 31 respectively touch the upper movable block 62, thereby driving the upper movable block 62 to rotate. The first top block 31 always touches the upper movable block 62 without a gap, thereby improving the stability during operation and thus improving the processing accuracy.

[0015] Second top blocks 32 are respectively provided on the left and right sides of the front and rear sides of the upper movable plate 3; the left and right sides of the second top block 32 are respectively in contact with the support column 11. The second top block 32 is set to limit the upper movable plate 3 in the left and right directions to prevent the upper movable plate 3 from swinging left and right, thereby further improving stability.

[0016] In the present design, the support column 11 is a square column. The arrangement of the square column facilitates the cooperation between the first top block 31 and the upper movable plate 3 and the cooperation between the second top block 32 and the support column 11 .

Therefore, the present design arranges the mounting seats 12 on the front and back sides above the support column 11, and directly installs the lifting drive device 2 on the top of the mounting seats 12, which is convenient for the disassembly and maintenance of the lifting drive device 2, and the connecting frame 13 connects the two mounting seats 12 to improve the stability of the frame.

[0018] It also includes four groups of elastic components 8; the elastic components 8 are respectively installed between the connecting frame 13 and the upper movable plate 3; the elastic component 8 includes a rod body 81 and a spring 82; the rod body 81 passes through the connecting frame 13 and the lower end is fixedly connected to the upper movable plate 3; the upper end of the rod body 81 has a limiting head; the spring 82 is sleeved on the rod body 81 and contacts between the limiting head and the connecting frame 13; the elastic component 8 is provided to buffer the upper movable plate 3 to prevent the product from being crushed.

[0019] The working principle of this embodiment:

[0020] When the angle of the upper movable plate 3 is adjusted by the four sets of lifting drive devices 2, a movable gap is reserved between the front and rear sides of the upper movable plate 3 and the support column 11 for the upper movable plate 3 to rotate. During the rotation of the upper movable plate 3, the four first top blocks 31 respectively touch the movable block 62, thereby driving the movable block 62 to rotate. The first top block 31 always touches the movable block 62 without a gap, thereby improving the stability during operation and thus improving the processing accuracy.
