[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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.

[0054] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Therefore, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, so that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0055] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0056] like Figure 1 As shown, at least one disclosed embodiment provides a mounting structure for a high-speed cylinder, comprising: a first mounting ring 1, and a second mounting ring 2, wherein an installation station is formed between the first mounting ring 1 and the second mounting ring 2 to install a high-speed cylinder 5; a clamping assembly 3 is provided on the inner wall of the second mounting ring 2, and the clamping assembly 3 always keeps in contact with the outer wall of the high-speed cylinder 5 to clamp the high-speed cylinder 5, thereby achieving that when a gap appears between the high-speed cylinder 5 and the second mounting ring 2, the high-speed cylinder 5 can still be clamped by the clamping assembly 3 to avoid shaking of the high-speed cylinder 5.

[0057] like Figure 2 and Figure 3 As shown, in an optional embodiment, the clamping assembly 3 includes: a plurality of arc-shaped parts 31; a plurality of grooves 21 are provided on the inner wall of the second mounting ring 2, and the grooves 21 are equidistantly arranged along the inner wall of the second mounting ring 2; the grooves 21 correspond to the arc-shaped parts 31; the arc-shaped parts 31 are made of elastic material, and one end of the arc-shaped parts 31 close to the first mounting ring 1 is connected to the inner wall of the corresponding groove 21; the other end of the arc-shaped parts 31 is movably arranged; the arched part of the arc-shaped parts 31 protrudes from the groove 21 of the inner wall of the second mounting ring 2 to contact the outer wall of the high-speed cylinder 5.

[0058] In this embodiment, since the arc-shaped parts 31 are made of elastic material, when the outer wall of the high-speed cylinder 5 contacts and squeezes the arc-shaped parts 31, each arc-shaped part 31 can clamp the high-speed cylinder 5. When the high-speed cylinder 5 is loosened due to vibration or other reasons, resulting in collision or friction between the high-speed cylinder 5 and the second mounting ring 2, the squeezed arc-shaped parts 31 can still maintain contact with the high-speed cylinder 5 and clamp the high-speed cylinder 5 by restoring a certain deformation, thereby avoiding the high-speed cylinder 5 from loosening and shaking, etc., and ensuring that the high-speed cylinder 5 meets the current usage requirements.

[0059] In this embodiment, one end of the arc-shaped member 31 is fixed and the other end is movably arranged, so that the arc-shaped member 31 can be deformed when squeezed and squeezed into the groove 21.

[0060] In an optional embodiment, a plurality of first through holes 22 are formed on a surface of the second mounting ring 2 away from the first mounting ring 1, and the first through holes 22 are connected to the inner wall of the corresponding groove 21; the movable end of the arc-shaped member 31 is located in the first through hole 22; when the outer wall of the high-speed cylinder 5 contacts and squeezes the arc-shaped member 31, the movable end of the arc-shaped member 31 extends out from the first through hole 22 to the side of the second mounting ring 2 away from the first mounting ring 1.

[0061] In this embodiment, when installing the high-speed cylinder 5, the movable end of the arc-shaped member 31 extends from the second mounting ring 2. At this time, the extended portion can be used for pre-positioning when installing the flange 4. The extended portion of the arc-shaped member 31 is aligned with the groove 41 and extends into the groove 41. At this time, the flange 4 is positioned, and the threaded groove 42 on the flange 4 is aligned with the threaded hole 24 on the second mounting ring 2, which facilitates the accurate installation of the flange 4.

[0062] In an optional embodiment, a second through hole 23 corresponding to the first through hole 22 is opened on the inner wall of the second mounting ring 2, and the second through hole 23 is connected to the first through hole 22; a first protrusion 32 is provided on the surface of the arc member 31 close to the axis of the second mounting ring 2; the first protrusion 32 is located in the corresponding second through hole 23, and the first protrusion 32 extends out of the second through hole 23 from the inner wall of the second mounting ring 2; the width of the first protrusion 32 is smaller than the diameter of the second through hole 23.

[0063] In this embodiment, the width of the first protrusion 32 is smaller than the diameter of the second through hole 23 , so that the first protrusion 32 can move in the second through hole 23 along the direction of the axis of the second mounting ring 2 .

[0064] In this embodiment, after the arc-shaped member 31 is squeezed so that the first protrusion 32 contacts the inner wall of the second through hole 23 , the second through hole 23 limits the maximum deformation degree of the arc-shaped member 31 , and the arc-shaped member 31 can better clamp the high-speed cylinder 5 .

[0065] like Figure 5 As shown, in an optional embodiment, a sealing groove 51 is opened circumferentially on the outer wall of the high-speed oil cylinder 5, and a sealing ring is arranged in the sealing groove 51; the sealing ring protrudes from the sealing groove 51; the first protrusion 32 contacts a side of the protruding part of the sealing ring away from the first mounting ring 1; when the first protrusion 32 moves toward the first mounting ring 1, the first protrusion 32 squeezes the sealing ring so that the outer diameter of the sealing ring increases.

[0066] In this embodiment, when the high-speed oil cylinder 5 is installed, the first protrusion 32 is farther away from the first installation ring 1 than the sealing ring.

[0067] In this embodiment, when the outer wall of the high-speed cylinder 5 is worn, the squeezing force of the high-speed cylinder 5 on the arc member 31 will be reduced. At this time, the arc member 31 will restore a certain deformation to keep the high-speed cylinder 5 clamped. In the process of the arc member 31 restoring the deformation, the first protrusion 32 will move toward the first mounting ring 1 to squeeze the sealing ring. The outer diameter of the sealing ring will increase after being squeezed, so that the seal between the high-speed cylinder 5 and the inner wall of the second mounting ring 2 can still be maintained when the outer wall of the high-speed cylinder 5 is worn.

[0068] In an optional embodiment, a second protrusion 33 is provided on a surface of the arc member 31 close to the axis of the second mounting ring 2, and the second protrusion 33 corresponds to the first through hole 22; the second protrusion 33 is farther away from the first mounting ring 1 than the first protrusion 32; when the movable end of the arc member 31 extends out of the first through hole 22 to a side of the second mounting ring 2 away from the first mounting ring 1, the second protrusion 33 extends out of the side of the second mounting ring 2 away from the first mounting ring 1.

[0069] like Figure 4 As shown, in an optional embodiment, a flange 4 is provided on the side of the second mounting ring 2 away from the first mounting ring 1; a groove 41 corresponding to the first through hole 22 is opened on the side of the flange 4 close to the second mounting ring 2, and the second protrusion 33 extends into the corresponding groove 41.

[0070] In this embodiment, when the flange 4 is installed, the second protrusion 33 extends into the corresponding groove 41. The shape of the cross section of the groove 41 can be approximately elliptical, and the second protrusion 33 can be approximately spherical and have a certain elasticity. After the second protrusion 33 extends into the groove 41, the second protrusion 33 can be clamped with the part of the groove 41 away from the first mounting ring 1. When the bolt 43 loosens and causes the flange 4 to loosen, the second protrusion 33 and the groove 41 can cooperate to prevent the flange 4 from loosening.

[0071] In an optional embodiment, a plurality of threaded holes 24 are provided on the second mounting ring 2, and the length direction of the threaded holes 24 is parallel to the axial direction of the second mounting ring 2; a threaded groove 42 corresponding to the threaded holes 24 is provided on the flange 4; and bolts 43 are passed through the threaded holes 24 and extended into the threaded grooves 42 to connect the second mounting ring 2 to the flange 4.

[0072] In this embodiment, in the initial state, the arched portion of the arc-shaped member 31 will extend out of the groove 21 to extend out of the inner wall of the second mounting ring 2, that is, the arched portion is closer to the axis of the second mounting ring 2 than the inner wall of the second mounting ring 2. At this time, the movable end of the arc-shaped member 31 is in the first through hole 22 and does not extend out of the second mounting ring 2. The high-speed cylinder 5 is installed between the first mounting ring 1 and the second mounting ring 2. The high-speed cylinder 5 will pass through the second mounting ring 2 to squeeze the arc-shaped member 31, and the arc-shaped member 31 will be squeezed and deformed. The movable end gradually extends out of the side wall of the second mounting ring 2. At this time, the second protrusion 33 extends out of the second mounting ring 2. The part of the arc-shaped member 31 extending out of the second mounting ring 2 can be used for pre-positioning when the flange 4 is installed. The arched part of the arc-shaped member 31 contacts the outer wall of the high-speed cylinder 5 to always keep the high-speed cylinder 5 clamped. After the high-speed cylinder 5 is installed on the outer wall, the flange 4 is installed. The part of the arc-shaped member 31 extending out of the second mounting ring 2 extends into the groove 41 on the flange 4 to complete the positioning of the flange 4. Then, the flange 4 is installed by the bolts 43.

[0073] When the high-speed cylinder 5 and the like are worn, a gap appears between the high-speed cylinder 5 and the inner wall of the second mounting ring 2, and the arc-shaped member 31 recovers its deformation to keep the high-speed cylinder 5 clamped. At the same time, the first protrusion 32 squeezes the sealing ring to keep it sealed, and the second protrusion 33 is clamped with the inner part of the groove 41 near the first mounting ring 1 to prevent the flange 4 from loosening.

[0074] In this embodiment, the number of the first through holes 22 on the second mounting ring 2 may be less than that of the arc-shaped member 31, that is, part of the arc-shaped member 31 may not need to extend out of the second mounting ring 2, and this part of the arc-shaped member 31 is only used for clamping the high-speed cylinder 5, and similarly, the first protrusion 32 and the second protrusion 33 are not provided on this part of the arc-shaped member 31.

[0075] At least one other disclosed embodiment also provides a method for using the above-mentioned high-speed oil installation structure, including: forming an installation station by a first installation ring 1 and a second installation ring 2 to install the high-speed oil cylinder 5; the clamping assembly 3 always contacts the outer wall of the high-speed oil cylinder 5 to clamp the high-speed oil cylinder 5.

[0076] To summarize, the installation structure of the high-speed cylinder 5 includes: a first installation ring 1, and a second installation ring 2, wherein an installation station is formed between the first installation ring 1 and the second installation ring 2 to install the high-speed cylinder 5; a clamping assembly 3 is provided on the inner wall of the second installation ring 2, and the clamping assembly 3 is always in contact with the outer wall of the high-speed cylinder 5 to clamp the high-speed cylinder 5, thereby achieving that when a gap appears between the high-speed cylinder 5 and the second installation ring 2, the high-speed cylinder 5 can still be clamped by the clamping assembly 3 to avoid shaking of the high-speed cylinder 5.
