[0027] like Figures 1 to 6 A single-drive bidirectional displacement positioning device is shown, comprising a frame 12 and a material discharging tray 9, one end of the material discharging tray 9 is a free end, the other end of the material discharging tray 9 is a fixed end, both ends of the material discharging tray 9 are installed with material detection sensors 3, and the material detection sensors 3 at both ends are arranged oppositely;

[0028] A rotating shaft support 28 is installed at one end of the frame 12, and a rotating seat 34 is installed at the fixed end of the discharge tray 9. The rotating seat 34 is connected to the rotating shaft support 28 through a radial spherical bearing assembly and rotates around the radial spherical bearing assembly.

[0029] A cylinder mounting seat 13 is installed at the other end of the frame 12, and a lifting cylinder 16 is installed on the cylinder mounting seat 13. A centripetal universal bearing assembly is installed on the protruding end of the lifting cylinder 16. The protruding end of the lifting cylinder 16 is connected to the free end of the discharge tray 9 to achieve lifting in one direction;

[0030] When the lifting cylinder 16 continues to extend, the radial spherical bearing assembly and the radial universal bearing assembly adapt to each other to achieve the tilting of the discharge tray 9 in another direction.

[0031] like Figure 6 As shown, the radial spherical bearing assembly includes a radial spherical bearing 30 and a first rotating shaft 26. The radial spherical bearing 30 is installed in the reference hole at the end of the rotating shaft support 28. The radial spherical bearing 30 is sleeved on the first rotating shaft 26. The first rotating shaft 26 at both ends of the radial spherical bearing 30 is sleeved with a first limit sleeve 27.

[0032] like Figure 5 As shown, the radial universal bearing assembly includes a rotating shaft seat 36, a radial universal bearing 8 and a second rotating shaft 19, wherein the second rotating shaft 19 is mounted on the rotating shaft seat 36, and the radial universal bearing 8 is mounted on the end of the cylinder piston rod of the lifting cylinder 16, and the radial universal bearing 8 is sleeved on the second rotating shaft 19, and the inner ring of the radial universal bearing 8 is in contact with the shoulder surface of the second rotating shaft 19; second limiting sleeves 37 are sleeved on the second rotating shaft 19 at both ends of the radial universal bearing 8, and the second limiting sleeves 37 are in contact with the end face of the inner ring of the radial universal bearing 8 to limit the radial universal bearing 8 axially.

[0033] like Figure 3 As shown, bearing limit buffers 7 are installed on both sides of the rotating shaft seat 36. These two sets of bearing limit buffers 7 can prevent damage during the rotation of the mechanism and can also achieve angle limitation of the lifting and positioning mechanism through position adjustment.

[0034] like Figure 1 , Figure 3 , Figure 4 As shown, an angle limit block 5 is installed on one side of the frame 12, and a limit block 20 matching the angle limit block 5 is installed on one side of the discharge tray 9. A universal ball 6 is installed on the angle limit block 5. The universal ball 6 contacts the upper plate surface of the limit block 20, and the angle is limited when the lifting cylinder 16 is extended and lifted.

[0035] like Figure 2 As shown, a linear guide 10 is installed on the bottom surface of the discharge tray 9, and the linear guide 10 is arranged along the length direction of the discharge tray 9. A slider matching with it is provided on the linear guide 10, and the slider is connected to the radial universal bearing assembly to guide the discharge tray 9 in the vertical direction during the lifting process.

[0036] like Figure 1 As shown, horizontal limit plates 2 are installed at both ends of the frame 12, and hydraulic buffers 14 and limit bolts 15 are installed on the top plate of the horizontal limit plate 2, so that the lifting and positioning device can be buffered and decelerated to a stop when falling back to prevent hard collision from causing damage to the mechanism. At the same time, the height of the horizontal limit plate 2 is less than the height of the angle limit block 5.

[0037] like Figure 2 As shown, a linear bearing 18 is also installed on the cylinder mounting seat 13, and a guide shaft 17 matching with it is installed in the linear bearing 18. A radial universal bearing assembly is installed on the guide shaft 17, and the radial universal bearing assembly is connected to the linear guide rail 10 through a slider.

[0038] like Figure 1As shown, a pad 23 is installed on the plate surface of the discharge tray 9, and the surface of the pad 23 is provided with a fish scale-like smooth layer to reduce the friction of the material (taking the slider as an example) during the process. Two positioning strips are installed on the pad 23, and the positioning strips are arranged along the length direction of the discharge tray 9, and a slideway 1 is formed between the two positioning strips to prevent the material from sliding.

[0039] Working process:

[0040] Step 1: In the initial state, the material tray 9 is in a horizontal state, and the material is placed in the slide 1. The material detection sensors 3 at the left and right ends detect the material in the slide 1;

[0041] Step 2: Tilt from right to left: When the lifting cylinder 16 extends, the cylinder piston rod of the lifting cylinder 16 drives the second rotating shaft 19, the second rotating shaft 19 drives the rotating shaft seat 36, and the rotating shaft seat 36 drives the right end of the discharge tray 9 to lift. During the lifting process, the left end of the discharge tray 9 is fixed to the rotating seat 34, and the rotating seat 34 rotates around the first rotating shaft 26, thereby realizing lifting in one direction;

[0042] Tilt from back to front: When lifted to a certain height, the universal ball 6 fixed on the angle limit block 5 contacts the limit block 20, limits the discharge tray 9, and the lifting cylinder 16 continues to extend, and the radial universal bearing 8 and the radial spherical bearing 30 installed at the rotating shaft support 28 adapt to the angle, thereby realizing tilting in another direction;

[0043] In summary, the bidirectional adjustment of the discharge tray 9 is achieved, so that the material is positioned in two directions at the same time;

[0044] Step 3: After the positioning of the materials in two directions is completed, the material tray 9 returns to the horizontal position to cooperate with the next sequence of loading;

[0045] Step 4: Repeat the above process.

[0046] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
