Abstract
Description
Technical Field
[0001] This utility model relates to the field of buffer device technology, and in particular to a buffer transition mechanism in a rotating working condition. Background Technology
[0002] Damping buffers are commonly used buffer components in existing mechanical equipment in extreme limit collision environments.
[0003] In existing technologies, the buffer end of a damping buffer is typically a piston rod that moves axially. When a damping buffer is used in rotational motion, it is repeatedly subjected to non-axial eccentric forces, resulting in the piston rod being subjected to high eccentric impact forces continuously. This can easily lead to accelerated wear of the internal bearings of the damping buffer, damage or bending of the piston rod, and seriously affect the actual service life of the damping buffer. Utility Model Content
[0004] To address the aforementioned issues, this application provides a buffer transition mechanism with a reasonable structure for use in rotating conditions, thereby effectively reducing or even avoiding non-axial force impacts on the buffer, helping to ensure the reliability and service life of the buffer, and offering good practicality.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A buffer transition mechanism for rotating operation includes a support base on which a tilting seat is rotatably mounted; it also includes a buffer mechanism mounted on the support base to buffer and limit the tilting seat to its extreme tilting position.
[0007] The structure of the buffer mechanism is as follows: it includes a mounting base installed on a support base, a mounting hole is opened through the mounting base, a buffer is installed at one end of the mounting hole, and an adapter is slidably installed at the other end of the mounting hole; one end of the adapter extends out of the mounting hole and is arranged in the flipping direction of the flipping base, and the other end of the adapter abuts against the buffer end of the buffer.
[0008] As a further improvement to the above technical solution:
[0009] The mounting hole is a stepped hole, including a small hole with a smaller diameter and a large hole with a larger diameter; the adapter extends from the large hole into the stepped hole and is installed through the small hole along the axial direction, and the adapter is limited by the step; the buffer is installed in the large hole and is locked to the threaded part at the opening of the large hole by external thread.
[0010] The end of the adapter that extends out of the mounting hole is configured as a convex spherical structure.
[0011] The buffer mechanism is provided in two sets, which correspond to the two extreme positions of the reciprocating flipping of the flipping seat.
[0012] The support base has a through hole in the middle for accommodating and flipping the flipping seat.
[0013] The top surface of the support base is equipped with supports at intervals, and the center of both ends of the flip base is equipped with end plates facing upwards. A rotating shaft is installed coaxially between the end plates and the corresponding supports. The flip base rotates relative to the support base with the rotating shaft as the center.
[0014] One set of buffer mechanisms is installed above the support base, and another set of buffer mechanisms is installed below the support base. The adapters of both sets of buffer mechanisms are arranged facing upwards, and the two adapters apply force to the front and bottom surfaces of the flip base respectively.
[0015] One of the shafts has a gear fitted on its outer end, which meshes with a vertical rack. The vertical rack is driven to move up and down by a linear drive.
[0016] The linear drive power is mounted on the side of the support base via a power seat. A lifting seat is slidably mounted on the side of the power seat, and the lifting seat is connected to the output end of the linear drive power. The vertical rack is mounted on the lifting seat.
[0017] A buffer plate is mounted on the protruding edge of the flip seat, and the outer end of the buffer mechanism adapter acts on the buffer plate.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] This utility model uses an adapter to directly bear the limiting load. As the adapter moves axially in the mounting hole, the adapter converts the non-axial force it receives into an axial force and transmits it to the buffer. Combined with the operation of the buffer, it plays a limiting and buffering role, effectively reducing or even avoiding the impact of non-axial forces on the buffer, which helps to ensure the reliability and service life of the buffer. It has good practicality. Attached Figure Description

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0032] like Figure 1 As shown, a buffer transition mechanism in a rotating condition according to this embodiment includes a support base 5, on which a flip seat 6 is rotatably mounted; it also includes a buffer mechanism 7 mounted on the support base 5, which buffers and limits the flip seat 6 to its flip limit position.
[0033] like Figure 3 As shown, the structure of the buffer mechanism 7 is as follows: it includes a mounting base 72 installed on the support base 5, a mounting hole is opened through the mounting base 72, a buffer 73 is installed at one end of the mounting hole, and an adapter 71 is slidably installed at the other end of the mounting hole; one end of the adapter 71 extends out of the mounting hole and is arranged in the flipping direction of the flipping base 6, and the other end of the adapter 71 abuts against the buffer end of the buffer 73.
[0034] In this embodiment, during the flipping process of the flipping seat 6 relative to the support seat 5, the flipping seat 6 will exert force on the buffer mechanism 7 at the extreme position; the adapter 71 in the buffer mechanism 7 directly bears the limiting load. As the adapter 71 moves axially in the mounting hole, the adapter 71 converts the non-axial force it receives into an axial force and transmits it to the buffer 73. Combined with the operation of the buffer 73, it plays a limiting and buffering role. In this process, the impact of non-axial force on the buffer 73 is effectively reduced or even avoided.
[0035] The mounting hole is a stepped hole, such as Figure 4 As shown, it includes a small hole 721 with a smaller diameter and a large hole 722 with a larger diameter; an adapter 71 extends from the large hole 722 into the stepped hole and is installed axially through the small hole 721, and the adapter 71 is limited by the step; a buffer 73 is installed in the large hole 722, and the buffer 73 is locked to the threaded part 723 at the opening of the large hole 722 via an external thread.
[0036] In this embodiment, the buffer 73 can be a standard product purchased from outside, such as a hydraulic buffer, which can achieve limit buffering.
[0037] In practical use, an external thread can be added to the purchased buffer 73 housing, or an additional housing with an external thread can be added to the purchased buffer 73. Both methods can achieve the installation of the buffer 73 on the mounting base 72.
[0038] In this embodiment, by locking a limiting nut 74 on the added housing, the buffer 73 is prevented from detaching from the housing during repeated force buffering.
[0039] The end of the adapter 71 extending out of the mounting hole is configured as a convex spherical structure. External forces are borne by the convex spherical structure and reliably converted into axial forces in the direction of movement.
[0040] Two sets of buffer mechanisms 7 are provided, and the two sets of buffer mechanisms 7 correspond to the two extreme positions of the reciprocating flipping of the flipping seat 6.
[0041] The support base 5 has a through hole 51 in the middle for accommodating and flipping the flip base 6.
[0042] In this embodiment, the flip seat 6 is flipped approximately 180° relative to the support seat 5, with the two extreme positions of the flip corresponding to two sets of buffer mechanisms 7.
[0043] Supports 41 are installed at intervals on the top surface of the support base 5. End plates 61 are installed at the middle of both ends of the flip base 6 with the middle facing upward. A rotating shaft 4 is installed coaxially between the end plate 61 and the corresponding support 41. The flip base 6 flips relative to the support base 5 with the rotating shaft 4 as the center.
[0044] In this embodiment, the configuration of the end plate 61 and the support 41 facilitates the layout and installation of the rotating shaft 4, and also moves the rotation axis of the flip seat 6 relative to the support seat 5 upward, which facilitates the layout of the buffer mechanism 7.
[0045] like Figure 1 and Figure 2 As shown, one set of buffer mechanisms 7 is installed above the support base 5, and another set of buffer mechanisms 7 is installed below the support base 5. The adapters 71 of both sets of buffer mechanisms 7 are arranged facing upwards, and the two adapters 71 apply force to the front and bottom surfaces of the flip base 6 respectively.
[0046] In actual use, as the flip seat 6 flips relative to the support seat 5, forces are applied sequentially to the two sets of buffer mechanisms 7.
[0047] One of the rotating shafts 4 has a gear 3 mounted on its outer end. The gear 3 meshes with a vertical rack 2, which is driven to move up and down by a linear drive power 1.
[0048] In this embodiment, the vertical rack 2 is driven to move up and down by the linear drive power 1, and the vertical rack 2 drives the meshing gear 3 to rotate, thereby driving the flipping seat 6 to flip via the rotating shaft 4; as the linear drive power 1 reciprocates, it drives the vertical rack 2 to move up and down, driving the gear 3 to rotate in the forward and reverse directions, thereby realizing the flipping seat 6 to flip back and forth relative to the support seat 5.
[0049] In this embodiment, the linear drive power 1 can be an existing standard product, such as a hydraulic cylinder, pneumatic cylinder, electric cylinder, etc., which can output reciprocating linear motion drive power.
[0050] The linear drive power 1 is mounted on the side of the support base 5 via the power seat 11. A lifting seat 21 is slidably mounted on the side of the power seat 11, and the lifting seat 21 is powered by the output end of the linear drive power 1. A vertical rack 2 is mounted on the lifting seat 21. Figure 5 As shown, the overall structure is reasonable and the layout is compact. The linear drive power 1 is supported and installed via the power base 11, while the vertical rack 2 is guided and moved up and down via the power base 11.
[0051] A buffer plate 60 is mounted on the protruding edge of the flip seat 6, and the outer end of the adapter 71 of the buffer mechanism 7 acts on the buffer plate 60.
[0052] In actual use, as the flipping seat 6 flips back and forth, the front and back sides of the buffer plate 60 successively touch and act on the corresponding buffer mechanism 7.
[0053] In this embodiment, the upper and lower sets of buffer mechanisms 7 can be the same interchangeable components, and the two sets of buffer mechanisms 7 are supported by the vertical plate 70 and installed on the top and bottom surfaces of the support base 5, respectively.
[0054] This invention effectively reduces or even avoids non-axial force impacts on the buffer, helping to ensure the reliability and service life of the buffer, and has good practicality.
[0055] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
