Description

Technical Field

[0001] The invention relates to the technical field of buffer devices, and in particular to a rotating buffer seat. Background Art

[0002] In machining, the processing of shaft parts often involves rotational motion, such as turning, grinding, and polishing of shafts, etc. In the process of shaft polishing, the shaft is often transported to the polishing equipment through a conveying device. The polishing equipment generally uses two or more grinding wheels for polishing, which drives the shaft to rotate during the polishing process. After the polishing is completed, the shaft will be transported out. Therefore, the shaft itself may have a certain rotational inertia in this process, and the existing buffer device often only has a single buffering effect, lacks this kind of buffering with rotational inertia, and the rotation of the shaft may also bring lateral impact. Based on this, the present invention proposes a rotating buffer seat. Summary of the invention

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Embodiment 1

[0046] like Figure 1-Figure 4 As shown, the present invention provides a rotating buffer seat, which mainly includes a substrate 1, a base plate 2 and a bearing part 3. The substrate 1 is a foundation, which is a fixed part and needs to be fixed on a fixed object in actual use. The fixed object in this embodiment is a general term and can be a fixed part on the equipment. For example, when the buffer seat is installed on a conveyor line, the substrate 1 is fixed on the conveyor line; the bearing part 3 is a displacement part, which is used to bear the impact of an object and act on the substrate 1; the base plate 2 and the substrate 1 are two fixed parts, which can be understood as an integrated structure in actual use. The main function of the base plate 2 is to provide a supporting surface for the first elastomer 5 described below.

[0047] Furthermore, a first elastic body 5 is provided between the bearing portion 3 and the base plate 2, and a second elastic body 6 is provided between the bearing portion 3 and the base plate 1;

[0048] Among them, the first elastic body 5 is a conical structure and a rotating body, having a closed end and a flared end, for example, it can be a rubber sleeve with a conical structure or a conical spring (such as a tower spring), the flared end of the first elastic body 5 is connected to the bearing part 3, and the closed end of the first elastic body 5 is connected to the base plate 2. There can be multiple combinations of connection methods at both ends of the first elastic body 5. To simplify the description, the closed end of the first elastic body 5 is named as the small end, and the flared end of the first elastic body 5 is named as the large end, as follows:

[0049] The big end is fixed on the bearing part 3, and the small end is rotatably arranged on the base plate 2; the big end is rotatably arranged on the bearing part 3, and the small end is fixed on the base plate 2; the big end and the small end are respectively rotatably arranged on the bearing part 3 and the base plate 2. It should be noted that when the big end or the small end is rotatably arranged, it cannot be separated; when the small end is rotatably arranged on the base plate 2, the small end cannot be separated from the base plate 2.

[0050] In this embodiment, considering that the bearing part 3 needs to tilt, it is preferred that the large end is fixed on the bearing part 3, the small end is rotatably arranged on the base plate 2, and an annular groove 21 for its rotation is provided on the base plate 2. In order to prevent it from being disengaged, for example, a plurality of sliders can be arranged in the annular groove 21, and the sliders and the annular groove 21 are connected in a T-shaped manner (such as the T-shaped groove 11 and T-shaped slider described below), and then the sliders are fixed on the large end. Other methods can also be used, which will not be described in detail here.

[0051] Combination Figure 4 As shown, the second elastic body 6 can be a common cylindrical spring; specifically, one end of the second elastic body 6 is pressed against the bearing portion 3 , and the other end of the second elastic body 6 is pressed against the substrate 1 .

[0052] A stop sleeve 12 is fixed on the base plate 1. The stop sleeve 12 provides an installation space for the second elastomer 6 on the one hand, and provides a limiting function on the other hand, for limiting the distance by which the bearing part 3 compresses the second elastomer 6. Further, a third elastomer 13 is fixed at the end of the stop sleeve 12 to prevent the bearing part 3 from directly colliding with the stop sleeve 12. The third elastomer 13 can be a rubber pad.

[0053] Based on the above, the bearing part 3 as a displacement member has at least the following states:

[0054] In the first state, the bearing part 3 has a rotational freedom relative to the substrate 1, and the rotational freedom includes the bearing part 3 rotating around the axis of the base plate 2 and the bearing part 3 tilting and rotating toward the base plate 2;

[0055] In the second state, the supporting portion 3 has the freedom to move along the axial direction of the base plate 2 relative to the substrate 1 .

[0056] Specifically, a first rotating shaft 31 is provided on the bearing part 3, and the first rotating shaft 31 is rotatably provided on the substrate 1. The first rotating shaft 31 penetrates the substrate 1 and extends outside the substrate 1, so that the bearing part 3 in the first state rotates around the axis of the base plate 2; wherein the second elastic body 6 is nested on the first rotating shaft 31.

[0057] Specifically, the substrate 1 is provided with a support portion 4, and the bearing portion 3 is rotatably disposed on the support portion 4 via a second rotating shaft 7, so that the bearing portion 3 in the first state is tilted and rotated toward the base plate 2; wherein the support portion 4 is rotatably disposed on the substrate 1;

[0058] Specifically, a slot 41 is provided on the bearing portion 3, and the second rotating shaft 7 is disposed in the slot 41. In order to prevent the second rotating shaft 7 from being separated from the slot 41, a limit block 42 is fixed at the end of the slot 41; wherein, when in the second state, the second rotating shaft 7 moves in the slot 41;

[0059] When the carrying portion 3 in the first state is tilted and rotated toward the base plate 2 , the second rotation shaft 7 rotates in the slot 41 .

[0060] Combination Figure 4 and Figure 5 As shown, the support part 4 is rotatably set by a T-shaped slider and a T-shaped slot 11, that is, a T-shaped slider is provided on the support part 4, and a ring-shaped T-shaped slot 11 is provided on the corresponding base plate 1, and the center of the T-shaped slot 11 coincides with the axis of the first rotating shaft 31.

[0061] Embodiment 2

[0062] On the basis of embodiment 1, in order to further improve the rotation stability of the bearing part 3, an extension part 8 is fixed on the base plate 1, and at least a part of the first rotating shaft 31 is located in the extension part 8 and is rotatably connected to the extension part 8; wherein the extension part 8 is fixed to the base plate 1 by a threaded connection.

[0063] Further, combined with Figure 6 and Figure 7 In order to improve the rotation stability of the bearing part 3 , a shaft sleeve 71 is arranged between the bearing part 3 and the second rotating shaft 7 , that is, two shaft sleeves 71 are arranged on the second rotating shaft 7 , and the bearing part 3 is nested on the two shaft sleeves 71 .

[0064] Furthermore, the second rotating shaft 7 is mounted on the supporting portion 4 through a nut. It should be noted that the nut cannot be completely tightened (i.e., the nut cannot be pressed against the supporting portion 4) to prevent the bearing portion 3 from being unable to rotate. In order to prevent the nut from loosening, Figure 6 As shown, it is possible to take Figure 6 For this nut, a through hole is provided on the second rotating shaft 7 and a pin is placed therein.

[0065] In addition, in the present application, because it involves rotation, movement and other displacements, lubricating substances such as lubricating oil can be added to reduce friction; especially when the first elastomer 5 rotates and the support part 4 rotates, balls can be set on the T-shaped structure to further reduce friction.

[0066] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
