[0026] The following is a detailed description of a tilting cylinder with flexible buffer provided by an embodiment of the present invention, with reference to the accompanying drawings.

[0027] Example

[0028] Figure 1 A three-dimensional structural diagram of a tilting cylinder with flexible buffer provided in an embodiment of the present invention is shown. Figure 2 A front view of a tilting cylinder with flexible cushioning provided in an embodiment of the present invention is shown; Figure 3 One of the perspective structural diagrams of the tilting cylinder with flexible buffer provided in the embodiment of the present invention is shown; Figure 4 This is a second perspective view of the tilting cylinder with flexible buffer provided in an embodiment of the present invention; Figure 5 A three-dimensional structural diagram of the base provided in an embodiment of the present invention is shown; Figure 6 A top view of the base provided in an embodiment of the present invention is shown; Figure 7 A three-dimensional structural diagram of the transmission block provided in an embodiment of this utility model is shown. Figures 1 to 7As shown, the flexible buffered tilting cylinder provided in this embodiment of the present invention is suitable for providing tilting action for parts or tooling fixtures, facilitating automated production. The flexible buffered tilting cylinder provided in this embodiment of the present invention includes: a cylinder assembly 1, a base 2, a transmission block 3, a connecting shaft assembly 4, a tilting plate 5, a filling assembly 6, a first buffer 10, and a second buffer 11; wherein the cylinder assembly 1 includes: a cylinder body 101 and a piston rod 102, wherein the cylinder body 101 and the piston rod 102 are drivenly connected to realize the reciprocating linear motion of the piston rod 102. The reciprocating linear motion of the piston rod 102 can be realized by controlling the gas supply to the cylinder body 101. The gas supply required for the cylinder body 101 is generally provided by the gas supply system in the production line. This embodiment fully utilizes the fast response speed of the cylinder assembly 1. The base 2 is mechanically connected to the cylinder assembly 1 to achieve mechanical fixation of the base 2, thus mechanically connecting the base 2 to the cylinder body 101. The transmission block 3 is hinged to the base 2 via a connecting shaft assembly 4 to allow the transmission block 3 to rotate around the connecting shaft assembly 4. The rotation range of the transmission block 3 is generally not less than 90 degrees, so that the transmission block 3 and the flipping plate 5 can maintain at least two states: horizontal and vertical. The flipping plate 5 is mechanically connected to the transmission block 3 to achieve the common flipping of the flipping plate 5 and the transmission block 3. The rotating action involves a piston rod 102 connected to a transmission block 3 via a rack and pinion mechanism to drive the transmission block 3 to rotate. This allows the transmission block 3 and the flipping plate 5 to rotate at any angle, from at least 0 degrees to 90 degrees, enabling the flipping plate 5, along with the components or tooling fixtures mounted on it, to flip. The rack and pinion mechanism between the piston rod 102 and the transmission block 3 ensures high transmission efficiency, a compact structure, and saves space. The first buffer 10 and the second buffer 11 are respectively positioned on the base 2 in two different directions to provide flexible buffering during the flipping of the flipping plate 5. The first buffer 10 is flexibly connected to the flipping plate 5 to provide flexible buffering in one direction (when the flipping plate 5 is horizontal), and the second buffer 11 is flexibly connected to the flipping plate 5 to provide flexible buffering in the other direction (when the flipping plate 5 is vertical). This avoids hard contact between the flipping plate 5 and the first positioning post 7 and the second positioning post 8 during the flipping action, reduces collisions between components, prevents premature damage, maintains good positioning accuracy, and improves the reliability of the components. It is worth noting that the first buffer 10 and the second buffer 11 are either mechanical buffers or hydraulic buffers. The specific position or height of the first buffer 10 and the second buffer 11 relative to the first positioning post 7 and the second positioning post 8 can be adjusted according to user needs and buffer type.

[0029] In the flexible buffered tilting cylinder provided by this utility model embodiment, the filling component 6 is set on the base 2 for filling with lubricating oil or grease to lubricate the piston rod 102 and the transmission block 3, thereby reducing the wear of moving parts such as the piston rod 102 and the transmission block 3 in the flexible buffered tilting cylinder, improving service life, reducing noise, and making the movement smoother. At the same time, the filling component 6 enables convenient and quick filling of lubricating oil or grease, effectively preventing the inconvenience of filling lubricating oil or grease due to the relatively closed internal space of the base 2 or the obstruction of other parts.

[0030] In the flexible buffer-equipped tilting cylinder provided in this embodiment of the utility model, specifically, the upper side of the piston rod 102 is provided with several gear teeth, thus forming a rack structure. The transmission block 3 is provided with a meshing part 301, which is at least a quarter-cylindrical structure. The meshing part 301 is provided with several gear teeth to achieve a gear rack connection with the upper end of the piston rod 102. The design of the meshing part 301 as at least a quarter-cylindrical structure ensures that the movement range of the transmission block 3 is not less than 90 degrees, thereby realizing the horizontal and vertical states of the transmission block 3 and the tilting plate 5. Of course, it can also realize any tilting angle state between 0 degrees and 90 degrees between the transmission block 3 and the tilting plate 5, which can adapt to more user needs.

[0031] In a flexible buffered tilting cylinder provided in this embodiment of the utility model, more specifically, the base 2 is provided with a base cavity 201 and a base opening 202, and the piston rod 102 and the transmission block 3 are both disposed in the base cavity 201. In this way, the base 2 can protect the piston rod 102 and the transmission block 3, avoid collisions, improve working reliability, and reduce external dust and other contamination. The relatively closed space of the base cavity 201 also facilitates the connection of the filling component 6 to the base cavity 201 for the filling of lubricating oil or grease, improves the smoothness of gear and rack movement, reduces movement wear, and increases the service life of the moving parts in the flexible buffered tilting cylinder. The lower end of the piston rod 102 is connected to the base opening 202 by a shaft hole. The cylinder 101 drives the piston rod 102 to perform reciprocating linear motion in the base cavity 201. The base opening 202 makes the piston rod 102 move more smoothly, improves the motion accuracy, and reduces the shaking phenomenon of the piston rod 102 during the movement.

[0032] As a further design improvement, the present invention provides a tilting cylinder with flexible buffer, which further includes at least one first positioning post 7 and at least one second positioning post 8. The first positioning post 7 and the second positioning post 8 are both disposed on the base 2. The number of the first positioning post 7 and the second positioning post 8 can be adjusted according to the shape of the tilting plate 5 or the load-bearing requirements. Figure 3 In this design, two first positioning posts 7 are provided, both positioned above the base 2 and evenly distributed. The first positioning posts 7 are in contact with the flipping plate 5 to limit the position of the flipping plate 5 in one direction (i.e., when the flipping plate 5 is in a horizontal state), making the support of the flipping plate 5 more stable. Two second positioning posts 8 are also provided, positioned on the side of the base 2 and evenly distributed. The second positioning posts 8 are in contact with the flipping plate 5 to limit the position of the flipping plate 5 in the other direction (i.e., when the flipping plate 5 is in a vertical state), making the support of the flipping plate 5 more stable. Here, the positioning accuracy of the flipping cylinder with flexible buffer is improved by using the first positioning posts 7 and the second positioning posts 8. In addition, the first positioning posts 7 and the second positioning posts 8 can also be set in the form of studs, which makes height adjustment convenient, thereby making the limiting points of the flipping plate 5 easy to adjust.

[0033] As a further design improvement, the present invention provides a rotating cylinder with flexible buffer, which further includes an adjusting shim 9. The adjusting shim 9 is disposed in the base cavity 201 on the base 2 and is in contact with the piston rod 102 to adjust the fit clearance between the piston rod 102 and the transmission block 3. The adjusting shim 9 is mechanically fixed on the base 2 and is in contact with the toothless side of the upper end of the piston rod 102. By using adjusting shims 9 of different thicknesses, the fit clearance between the piston rod 102 and the transmission block 3 can be adjusted, thereby ensuring smoother movement and avoiding the shaking phenomenon of the transmission block 3 and the rotating plate 5 caused by excessive gear and rack movement clearance.

[0034] Compared to existing technologies, the present invention provides a reasonably designed tilting cylinder with flexible buffer. Utilizing a unique structural design of the piston rod 102, base 2, transmission block 3, and two buffers, the tilting action of the cylinder with flexible buffer is achieved. The movement is smooth and rapid, with good buffering effect, compact structure, and space saving. The lubrication component 6 facilitates lubrication of the tilting cylinder with flexible buffer, making lubrication convenient and quick, reducing wear and tear, and improving service life. The tilting cylinder with flexible buffer provided by this invention is suitable for automated mass production assembly, meets specific user needs, and can be used in assembly fields such as automobiles, ships, and aerospace.
