[0016] And / or, along the direction of movement of the floating joint body, the orthographic projection of the second arcuate surface onto the second profile covers the second profile.

[0017] As an optional implementation, the gasket assembly has a third profile. Along the moving direction of the floating connector body, the third profile is located on the side of the first profile away from the floating connector body, and the shape of the third profile matches the shape of the opposite cavity wall of the mounting cavity; when the first profile and the first arcuate surface abut together, the third profile abuts together with the corresponding cavity wall of the mounting cavity.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0047] First, see Figure 1 The direction of movement of the floating joint body 120 is defined as Q.

[0048] Firstly, combining Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a floating joint mechanism 100, including a receiving member 110, a floating joint body 120, and a gasket assembly 130.

[0049] The receiving component 110 has a mounting cavity 111. A floating connector body 120 is located within the mounting cavity 111. The floating connector body 120 has a first arcuate surface 121 and a second arcuate surface 122, which are positioned opposite each other along the moving direction of the floating connector body 120. A gasket assembly 130 is disposed within the mounting cavity 111. The gasket assembly 130 has a first profile surface 131 facing the first arcuate surface 121 and conforming to its shape, and a second profile surface 132 facing the second arcuate surface 122 and conforming to its shape. When the floating connector body 120 moves within the mounting cavity 111, the first profile surface 131 and the first arcuate surface 121 engage in contact, or the second profile surface 132 engages in contact with the second arcuate surface 122.

[0050] See Figure 1 , Figure 3 and Figure 4Understandably, when the floating joint body 120 moves along the Q direction toward the side where the receiving member 110 is located, the first profile 131 and the first arc-shaped surface 121 form surface contact. When the floating joint body 120 moves along the Q direction toward the side away from the receiving member 110, the second profile 132 and the second arc-shaped surface 122 form surface contact. During the movement, the floating joint body 120 eliminates the bending load caused by the tilt of the floating joint body 120 relative to the Q direction due to mechanical errors, avoids stress concentration in the floating joint body 120, and can prevent structural deformation of the floating joint body 120, thereby extending the service life of the floating joint mechanism 100.

[0051] Combination Figure 1 and Figure 2 As an optional implementation, the receiving component 110 includes a receiving body 112 and a connecting plate 113. The connecting plate 113 is connected to one side of the receiving body 112, and the connecting plate 113 and the receiving body 112 together form an installation cavity 111.

[0052] As will be understood by those skilled in the art, the curvature of the first arc surface 121 and the second arc surface 122 in this embodiment may be the same or different. Furthermore, the curvature of the first arc surface 121 and the second arc apex surface may be the same or different. This application embodiment does not require this.

[0053] For example, the receiving component 110, the floating joint body 120, and the gasket assembly 130 in the embodiments of this application may be made of 40Cr13.

[0054] See Figure 3 As an optional implementation, along the moving direction (Q) of the floating joint body 120, the first arcuate surface 121 protrudes towards the side where the first profile surface 131 is located relative to the center of the floating joint body 120. And / or, along the moving direction (Q) of the floating joint body 120, the second arcuate surface 122 protrudes towards the side where the second profile surface 132 is located relative to the center of the floating joint body 120.

[0055] As those skilled in the art will understand, the shape of the first profile 131 matches the shape of the first arcuate surface 121, and the first profile 131 is recessed relative to the center of the gasket assembly 130 towards the side opposite to the first arcuate surface 121. When the floating joint body 120 moves toward the side where the first profile 131 is located, and during the contact between the first arcuate surface 121 and the first profile 131, the first profile 131 and the first arcuate surface 121 form a guiding effect on each other to fix the position of the floating joint body 120. This can eliminate the bending load generated by the tilt of the floating joint body 120 relative to the Q direction, avoid stress concentration in the floating joint body 120, and thus prevent structural deformation of the floating joint body 120, thereby extending the service life of the floating joint mechanism 100.

[0056] Similarly, the shape of the second profile 132 matches the shape of the second arcuate surface 122, with the second profile 132 recessed relative to the center of the gasket assembly 130 towards the side opposite to the second arcuate surface 122. When the floating joint body 120 moves toward the side where the second profile 132 is located, and during the contact between the second arcuate surface 122 and the second profile 132, the second profile 132 and the second arcuate surface 122 form a guiding effect on each other to fix the position of the floating joint body 120, thereby avoiding bending loads caused by the tilt of the floating joint body 120 relative to the Q direction, avoiding stress concentration in the floating joint body 120, preventing structural deformation of the floating joint body 120, and thus extending the service life of the floating joint mechanism 100.

[0057] See Figure 3 As an optional implementation, both the first arc surface 121 and the second arc surface 122 are spherical, and the diameter of the first arc surface 121 and the diameter of the second arc surface 122 are the same.

[0058] In this embodiment, both the first arc-shaped surface 121 and the second arc-shaped surface 122 are smooth and continuous spherical curved surfaces. The first profile 131 and the first arc-shaped surface 121 are matched with each other, and the second profile 132 and the second arc-shaped surface 122 are matched with each other. In this way, the first profile 131 and the first arc-shaped surface 121 can be adjusted at multiple angles when they abut against each other, which further corrects the position of the floating joint body 120, so that the position of the floating joint body 120 is returned to the correct position, eliminating the bending load caused by mechanical error of the floating joint body 120, thereby extending the service life of the floating joint mechanism 100.

[0059] It should be noted that the structure of the second arc-shaped surface 122 and the second shaped surface 132 in this embodiment is similar to that of the first arc-shaped surface 121 and the first shaped surface 131, and they have the same function, so they will not be described again.

[0060] As will be understood by those skilled in the art, the embodiments of this application facilitate the manufacture of the floating joint body 120 by using the first arc-shaped surface 121 and the second arc-shaped surface 122 with the same diameter. Furthermore, the first profile 131 and the second profile 132 of the gasket assembly 130 are respectively adapted to the first arc-shaped surface 121 and the second arc-shaped surface 122, which also facilitates the production of the gasket assembly 130 and the assembly between the gasket assembly 130 and the floating joint body 120.

[0061] As an optional implementation, along the moving direction (Q) of the floating joint body 120, the orthographic projection of the first arcuate surface 121 on the first profile 131 covers the first profile 131; and / or, along the moving direction (Q) of the floating joint body 120, the orthographic projection of the second arcuate surface 122 on the second profile 132 covers the second profile 132.

[0062] In some embodiments, along the Q direction, the size of the first arcuate surface 121 projected onto the first profile 131 can be the same as the size of the first profile 131. That is, when the first arcuate surface 121 and the first profile 131 are in contact, the first arcuate surface 121 and the first profile 131 completely overlap.

[0063] In some embodiments, along the Q direction, the size of the first arcuate surface 121 in the orthographic projection of the first profile surface 131 can be larger than the size of the first profile surface 131. That is, the first profile surface 131 is located within the orthographic projection of the first arcuate surface 121 in the first profile surface 131. When the first arcuate surface 121 and the first profile surface 131 are engaged and abutted, the first arcuate surface 121 and the first profile surface 131 partially overlap.

[0064] It is easy to understand that this embodiment increases the contact area between the first surface 131 and the first arc surface 121 by setting the first surface 131 and the first arc surface 121, so that the first surface 131 forms a stable constraint and guiding effect on the first arc surface 121, ensuring that the position of the floating joint body 120 can be corrected, thereby improving the service life of the floating joint mechanism 100.

[0065] It should be noted that, along the Q direction, the size of the orthographic projection of the second arc-shaped surface 122 onto the second profile surface 132 can be the same as the size of the second profile surface 132. That is to say, when the second arc-shaped surface 122 and the second profile surface 132 are in contact, the second arc-shaped surface 122 and the second profile surface 132 completely overlap.

[0066] In some embodiments, along the Q direction, the size of the second arcuate surface 122 in the orthographic projection of the second profile surface 132 can be larger than the size of the second profile surface 132. That is, the second profile surface 132 is located within the orthographic projection of the second arcuate surface 122 in the second profile surface 132. When the second arcuate surface 122 and the second profile surface 132 are engaged and abutted, the second arcuate surface 122 and the second profile surface 132 partially overlap.

[0067] Those skilled in the art, in conjunction with the foregoing embodiments, can understand the interaction between the second arcuate surface 122 and the second shaped surface 132 in this embodiment, which will not be elaborated further.

[0068] See Figure 1 , Figure 2 and Figure 4 Optionally, the gasket assembly 130 has a third profile 133. Along the moving direction (Q) of the floating connector body 120, the third profile 133 is located on the side of the first profile 131 opposite to the floating connector body 120, and the shape of the third profile 133 matches the shape of the opposite cavity wall of the mounting cavity 111. When the first profile 131 and the first arcuate surface 121 abut, the third profile 133 abuts against the cavity wall of the corresponding mounting cavity 111. And / or, the gasket assembly 130 has a fourth profile 134. Along the moving direction (Q) of the floating connector body 120, the fourth profile 134 is located on the side of the second profile 132 opposite to the floating connector body 120, and the shape of the fourth profile 134 matches the shape of the opposite cavity wall of the mounting cavity 111. When the second profile 132 and the second arcuate surface 122 abut, the fourth profile 134 abuts against the cavity wall of the corresponding mounting cavity 111.

[0069] Combination Figure 1 and Figure 2 The mounting cavity 111 has a first cavity wall 114 and a second cavity wall 115, which are opposite each other along the Q direction. The floating joint body 120 and the gasket assembly 130 are mounted between the first cavity wall 114 and the second cavity wall 115.

[0070] Combination Figure 2 and Figure 3The shape of the first cavity wall 114 matches the shape of the third surface 133. When the floating joint body 120 moves along the Q direction toward the side where the first surface 131 is located, the first arcuate surface 121 of the floating joint body 120 and the first surface 131 of the gasket assembly 130 abut together, and the third surface 133 of the gasket assembly 130 abuts together with the first cavity wall 114. In this way, a surface contact is formed between the first cavity wall 114 and the third surface 133, avoiding point contact between the first cavity wall 114 and the gasket assembly 130, thereby improving the stability of the floating joint body 120 in the mounting cavity 111, eliminating the bending load caused by the tilt of the floating joint body 120, and further extending the service life of the floating joint mechanism 100.

[0071] Combination Figure 2 and Figure 3 The shape of the second cavity wall 115 matches the shape of the fourth surface 134. When the floating joint body 120 moves along the Q direction toward the side where the second surface 132 is located, the second arcuate surface 122 of the floating joint body 120 and the second surface 132 of the gasket assembly 130 abut together, and the fourth surface 134 of the gasket assembly 130 abuts together with the second cavity wall 115. In this way, a surface contact is formed between the second cavity wall 115 and the fourth surface 134, avoiding point contact between the second cavity wall 115 and the gasket assembly 130, thereby improving the stability of the floating joint body 120 in the mounting cavity 111, eliminating the bending load caused by the tilting of the floating joint body 120, and further extending the service life of the floating joint mechanism 100.

[0072] Understandably, the third surface 133 can be a concave-convex surface, and the first cavity wall 114 is a concave-convex surface that matches the third surface 133.

[0073] In some embodiments, the fourth surface 134 can be a concave-convex surface, and the second cavity wall 115 is a concave-convex surface that matches the fourth cavity wall 117.

[0074] Optionally, at least one of the third surface 133 and the fourth surface 134 is a flat surface.

[0075] For example, see Figure 2 and Figure 4In this embodiment, the third surface 133 is a straight surface, the first cavity wall 114 is a plane, the fourth surface 134 is a straight surface, and the second cavity wall 115 is a plane. This arrangement facilitates the manufacturing of the support and the gasket assembly 130. It is understood that the first cavity wall 114 and the third surface 133 form planar contact when mated, and the second cavity wall 115 and the fourth surface 134 also form planar contact when mated. Thus, through the arcuate contact between the gasket assembly 130 and the floating joint body 120, and the planar contact between the gasket assembly 130 and the cavity wall of the mounting cavity 111, mechanical errors between the floating joint body 120 and the cavity wall of the mounting cavity 111 are eliminated, thereby eliminating the bending load caused by the tilting of the floating joint body 120 and further extending the service life of the floating joint mechanism 100.

[0076] See Figure 4 The direction perpendicular to the movement direction of the floating joint body 120 is defined as P.

[0077] Combination Figure 1 , Figure 2 , Figure 4 In this embodiment, when the floating connector body 120 is not moving, the minimum distance between the two opposing cavity walls of the floating connector body 120 and the mounting cavity 111 along the direction of movement (P) perpendicular to the floating connector body 120 is a first distance, which is greater than or equal to 2.5 mm. And / or, when the floating connector body 120 moves within the mounting cavity 111, the minimum distance between the two opposing cavity walls of the floating connector body 120 and the mounting cavity 111 along the direction of movement (P) perpendicular to the floating connector body 120 is a second distance, which is greater than or equal to 0.5 mm.

[0078] As will be understood by those skilled in the art, the mounting cavity 111 has a third cavity wall 116 and a fourth cavity wall 117, which are opposite each other along the P direction. The two ends of the third cavity wall 116 along the P direction are respectively connected to the first cavity wall 114 and the second cavity wall 115, and the two ends of the fourth cavity wall 117 along the P direction are respectively connected to the first cavity wall 114 and the second cavity wall 115.

[0079] When the floating connector body 120 is not moving, the distance between the floating connector body 120 and the third cavity wall 116 is equal to the distance between the floating connector body 120 and the fourth cavity wall 117, and this distance is defined as the first distance. Alternatively, when the distance between the third cavity wall 116 and the floating connector body 120 is different from the distance between the fourth cavity wall 117 and the floating connector body 120, the distances between the third cavity wall 116 and the fourth cavity wall 117 and the floating connector body 120 are respectively defined as the first distance. It can be understood that the first distance forms an installation allowance for the mounting cavity 111 and the floating connector body 120 along the P direction, so that the floating connector body 120 can float in the mounting cavity 111 along the P direction.

[0080] For example, the first spacing can be 2.5mm, 3mm, 5mm, etc., and this application embodiment does not make specific requirements for it.

[0081] When the floating joint body 120 moves along the Q direction, the minimum distance between the floating joint body 120 and the third cavity wall 116 and the fourth cavity wall 117 is the second distance. For example, the second distance can be 0.5mm, f.3mm, etc., and this embodiment does not specify a particular value. It is understood that when the floating joint body 120 moves along the Q direction and separates from the first arcuate surface 121 and the first profile surface 131, and also separates from the second arcuate surface 122 and the second profile surface 132, the floating joint body 120 is in a relatively free state. The minimum distance between the floating joint body 120 and the third profile surface 133 and the fourth profile surface 134 is greater than or equal to 0.5mm, ensuring that the floating body does not interfere with the third cavity wall 116 and the fourth cavity wall 117, thus allowing the floating joint body 120 to move smoothly, reducing friction between the floating joint body 120 and the third cavity wall 116 and the fourth cavity wall 117, and extending the service life of the floating joint mechanism 100.

[0082] Combination Figure 1 , Figure 2 and Figure 4 Along the direction of movement (P) perpendicular to the floating joint body 120, the minimum distance between the two cavity walls opposite to the gasket assembly 130 and the mounting cavity 111 is the third distance, which is greater than or equal to the difference between the first distance and the second distance.

[0083] As can be understood from the foregoing embodiments, along the P direction, there is a gap between the gasket assembly 130 and the third cavity wall 116, and a gap between the gasket assembly 130 and the fourth cavity wall 117. The minimum gap between the gasket assembly 130 and the third cavity wall 116 and the fourth cavity wall 117 is the third gap. The gasket assembly 130 can move within the mounting cavity 111, and the gasket assembly 130 will not contact the third cavity wall 116 and the fourth cavity wall 117, thus avoiding an imbalance of forces on the floating joint body 120 and further preventing the floating joint body 120 from being subjected to bending loads, thereby extending the service life of the floating joint mechanism 100.

[0084] See Figure 1 and Figure 4 The floating joint mechanism 100 in this embodiment further includes a connecting portion 140, which is disposed on the second arcuate surface 122 and extends to the outside of the mounting cavity 111 along the movement direction (Q) of the floating joint body 120. The connecting portion 140 extends to the outside of the mounting cavity 111 to facilitate the connection between the floating joint body 120 and the external drive member 210.

[0085] For example, the gasket assembly 130 includes a first gasket 135 and a second gasket 136. A first arcuate surface 121 is disposed on the first gasket 135, and a second arcuate surface 122 is disposed on the second gasket 136. The second gasket 136 has a connecting hole 1361, and the second gasket 136 is sleeved onto the connecting portion 140 through the connecting hole 1361. It is easy to understand that a third shaped surface 133 is disposed on the first gasket 135, and a fourth shaped surface 134 is disposed on the second gasket 136.

[0086] It should be noted that the connecting hole 1361 in this embodiment can be a hole-like structure or a tubular structure, etc. The shape of the hole-like structure or tubular structure can be circular, square, etc., and there are no requirements in this regard.

[0087] When the floating joint body 120 moves within the mounting cavity 111, along the direction of movement (P) perpendicular to the floating joint body 120, the minimum distance between the hole wall of the connecting hole 1361 and the two opposing side walls of the connecting portion 140 is a fourth gap, which is greater than or equal to 1 mm. This gap between the second gasket 136 and the connecting portion 140 facilitates their assembly. Furthermore, the second gasket 136 is movable relative to the connecting portion 140, thereby guiding the floating joint body 120 back to its correct position through the engagement of the second profile 132 and the second arcuate surface 122, eliminating bending loads on the floating joint body 120, and thus extending the service life of the floating joint mechanism 100.

[0088] For example, the fourth spacing can be 1mm, 1.5mm, 3mm, etc. This application embodiment does not make specific requirements for this, and any value within the above range is acceptable.

[0089] See Figure 5 Secondly, embodiments of this application provide a hot pressing device 200, including: the floating joint mechanism 100 in the first aspect and a driving member 210, wherein the driving member 210 is connected to the floating joint body 120 of the floating joint mechanism 100 to drive the floating joint body 120 to move.

[0090] For example, in combination Figure 1 and Figure 5 The drive component 210 is connected to the floating joint body 120 via the connecting part 140.

[0091] The hot pressing device 200 in this embodiment includes the floating joint mechanism 100 in the aforementioned embodiment, which can extend the service life of the hot pressing device 200.

[0092] In some implementations, the number of floating joint mechanisms 100 can be multiple.

[0093] It should be noted that the embodiments referred to in the specification, such as "one embodiment," "embodiment," "exemplary embodiment," and "some embodiments," may include specific features, structures, or characteristics, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0094] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "one" can be understood to convey either singular or plural usage.

[0095] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0096] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
