Description
Technical Field
[0001] This invention relates to the field of workpiece machining and positioning technology, and in particular to a single-drive bidirectional displacement positioning device. Background Technology
[0002] In existing technologies, when positioning materials in two directions, two cylinders are usually used in parallel, which is costly, complex, and difficult to ensure positioning accuracy when multiple materials are fed at the same time. It requires manual coordination, has large operating space requirements, and is not very adaptable. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a single-drive bidirectional displacement positioning device that simultaneously lifts the feeding tray at two angles by means of a lifting cylinder, in conjunction with a radial universal bearing and a radial spherical bearing, in order to solve the problems existing in the prior art mentioned above.
[0004] The technical solution adopted by the present invention to solve its technical problem is: a single-drive bidirectional displacement positioning device, including a frame and a feeding tray, wherein one end of the feeding tray is a free end and the other end of the feeding tray is a fixed end;
[0005] One end of the frame is equipped with a rotating shaft support, and the fixed end of the feeding tray is equipped with a rotating seat. The rotating seat and the rotating shaft support are connected by a radial joint bearing assembly and rotate around the radial joint bearing assembly.
[0006] A cylinder mounting base is installed at the other end of the frame. A lifting cylinder is installed on the cylinder mounting base. A radial universal bearing assembly is installed on the extended end of the lifting cylinder. The extended end of the lifting cylinder is connected to the free end of the feeding tray to achieve lifting in one direction.
[0007] As the lifting cylinder continues to extend, the radial joint bearing assembly and the radial universal bearing assembly adapt their angles to achieve tilting of the feeding tray in the other direction.
[0008] Furthermore, the radial spherical bearing assembly includes a radial spherical bearing and a first rotating shaft. The radial spherical bearing is installed in the reference hole at the end of the rotating shaft support, and the radial spherical bearing is sleeved on the first rotating shaft. A first limiting sleeve is sleeved on both ends of the first rotating shaft.
[0009] Furthermore, the radial universal bearing assembly includes a shaft seat, a radial universal bearing, and a second shaft. The second shaft is mounted on the shaft seat. The piston rod end of the lifting cylinder is equipped with a radial universal bearing. The radial universal bearing is sleeved on the second shaft. Second limiting sleeves are sleeved on both ends of the second shaft.
[0010] Furthermore, bearing limit buffers are installed on both sides of the shaft seat.
[0011] Furthermore, an angle limiting block is installed on one side of the frame, and a limiting block that cooperates with the angle limiting block is installed on one side of the feeding tray. A universal ball is installed on the angle limiting block, and the universal ball contacts the upper plate surface of the limiting block.
[0012] Furthermore, a linear guide rail is installed on the bottom surface of the feeding tray. The linear guide rail is set along the length direction of the feeding tray, and a slider that cooperates with it is provided on the linear guide rail. The slider is connected to the radial universal bearing assembly.
[0013] Furthermore, horizontal limit plates are installed at both ends of the frame, and hydraulic buffers and limit bolts are installed on the top plate of the horizontal limit plates. The height of the horizontal limit plates is less than the height of the angle limit blocks.
[0014] Furthermore, a linear bearing is also installed on the cylinder mounting base, and a guide shaft that mates with it is installed inside the linear bearing. A radial universal bearing assembly is installed on the guide shaft, and the radial universal bearing assembly is connected to the linear guide rail via a slider.
[0015] Furthermore, both ends of the feeding tray are equipped with material absence detection sensors, which are positioned opposite each other.
[0016] Furthermore, a pad is installed on the surface of the feeding tray. The surface of the pad has a fish-scale-like smooth layer to reduce the friction of the material during the process. Two positioning strips are installed on the pad. The positioning strips are set along the length of the feeding tray, and a channel is formed between the two positioning strips to prevent the material from slipping.
[0017] The beneficial effects of this invention are as follows: This invention uses a lifting cylinder to lift the material tray at two angles simultaneously, in conjunction with a radial universal bearing and a radial spherical bearing. During the lifting process, the material is positioned in two directions at the same time, and no additional positioning elements are required, which shortens the material loading and unloading cycle and enables rapid loading and unloading. Furthermore, it does not require manual operation and has a high space utilization rate. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.
[0027] like Figures 1-6 The single-drive bidirectional displacement positioning device shown includes a frame 12 and a feeding tray 9. One end of the feeding tray 9 is a free end, and the other end of the feeding tray 9 is a fixed end. Both ends of the feeding tray 9 are equipped with a material absence detection sensor 3, which is arranged opposite to each other.
[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 feeding tray 9. The rotating seat 34 is connected to the rotating shaft support 28 through a radial joint bearing assembly and rotates around the radial joint bearing assembly.
[0029] A cylinder mounting base 13 is installed at the other end of the frame 12. A lifting cylinder 16 is installed on the cylinder mounting base 13. A radial universal bearing assembly is installed on the extended end of the lifting cylinder 16. The extended end of the lifting cylinder 16 is connected to the free end of the feeding tray 9 to achieve lifting in one direction.
[0030] As the lifting cylinder 16 continues to extend, the radial joint bearing assembly and the radial universal bearing assembly adapt their angles to achieve tilting of the feeding disc 9 in another direction.
[0031] like Figure 6 As shown, the radial joint bearing assembly includes a radial joint bearing 30 and a first rotating shaft 26. The radial joint bearing 30 is installed in the reference hole at the end of the rotating shaft support 28. The radial joint bearing 30 is sleeved on the first rotating shaft 26. A first limiting sleeve 27 is sleeved on both ends of the first rotating shaft 26.
[0032] like Figure 5 As shown, the radial universal bearing assembly includes a shaft seat 36, a radial universal bearing 8, and a second shaft 19. The second shaft 19 is mounted on the shaft seat 36. The piston rod end of the lifting cylinder 16 is equipped with the radial universal bearing 8, which is sleeved on the second shaft 19. The inner ring of the radial universal bearing 8 contacts the shoulder surface of the second shaft 19. Second limiting sleeves 37 are sleeved on both ends of the second shaft 19. The second limiting sleeves 37 contact the end face of the inner ring of the radial universal bearing 8 to axially limit the radial universal bearing 8.
[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 limit the angle of the lifting positioning mechanism by adjusting the position.
[0034] like Figure 1 , Figure 3 , Figure 4 As shown, an angle limiting block 5 is installed on one side of the frame 12, and a limiting block 20 that cooperates with the angle limiting block 5 is installed on one side of the feeding tray 9. A universal ball 6 is installed on the angle limiting block 5. The universal ball 6 contacts the upper plate surface of the limiting block 20. When the lifting cylinder 16 extends and lifts, it performs angle limiting.
[0035] like Figure 2 As shown, a linear guide rail 10 is installed on the bottom surface of the feeding tray 9. The linear guide rail 10 is set along the length direction of the feeding tray 9. A slider that cooperates with the linear guide rail 10 is provided on the linear guide rail 10. The slider is connected to the radial universal bearing assembly to guide the feeding 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. A hydraulic buffer 14 and a limit bolt 15 are installed on the top plate of the horizontal limit plate 2, so that the lifting and positioning device can buffer and decelerate to stop when it falls back, so as to prevent hard collisions from damaging 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 base 13. A guide shaft 17 that mates with the linear bearing 18 is installed inside the linear bearing 18. A radial universal bearing assembly is installed on the guide shaft 17. 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 surface of the feeding tray 9. 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. The positioning strips are set along the length of the feeding tray 9, and a track 1 is formed between the two positioning strips to prevent the material from sliding.
[0039] Work process:
[0040] Step 1: In the initial state, the feeding tray 9 is in a horizontal state. The material is placed in the slide 1, and the material presence and absence detection sensors 3 at both ends detect the material in the slide 1.
[0041] Step 2: Tilting from right to left: When the lifting cylinder 16 extends, the 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 feeding plate 9 to lift. During the lifting process, the left end of the feeding plate 9 is fixed to the rotating seat 34, and the rotating seat 34 rotates around the first rotating shaft 26, thereby achieving lifting in one direction;
[0042] Tilting from back to front: When it is lifted to a certain height, the universal ball 6 fixed on the angle limiting block 5 contacts the limiting block 20, limiting the material feeding plate 9. 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 achieving tilting in another direction.
[0043] In summary, the material feeding tray 9 can be adjusted in both directions, thereby positioning the material in two directions simultaneously.
[0044] Step 3: After the material is positioned in both directions, the feeding tray 9 returns to the horizontal position to cooperate with the next feeding sequence;
[0045] Step 4: Repeat the above process.
[0046] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
