[0047] Example embodiments will now be described more fully with reference to the accompanying drawings. However, it should not be construed that the embodiments of this disclosure are limited to those described herein. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0048] In one aspect, this disclosure provides a clamping assembly 30, which may include a hanger 31 and a clamping frame. The hanger 31 can be used to connect a lifting device. The lifting device can lift the hanger 31 upward to create a tilting space below the hanger 31, facilitating the tilting of the clamping frame.

[0049] Reference Figure 1 The clamping frame can be rotatably connected to the hanger 31 around the rotation axis. The clamping frame can be used to clamp the object to be clamped. During the rotation of the clamping frame relative to the hanger 31, the object to be clamped can rotate together with the clamping frame relative to the hanger 31, thereby realizing the flipping of the object to be clamped.

[0050] Specifically, the clamping frame may include a first clamping frame 1 and a second clamping frame 2. The first clamping frame 1 and the second clamping frame 2 are rotatably connected to the two ends of the hanger 31 along the extension direction of the rotation axis. At least one of the first clamping frame 1 and the second clamping frame 2 can move along the extension direction of the rotation axis, so that the first clamping frame 1 and the second clamping frame 2 can move closer to each other or further apart to clamp or release the opposite sides of the object to be clamped.

[0051] In this embodiment, the first clamping frame 1 and the second clamping frame 2 are close to each other, and can be clamped on opposite sides of the object to be clamped, thereby achieving reliable clamping of the object. At this time, the clamping frame is reliably installed on the object to be clamped, which improves the safety of the operation site and provides the possibility for subsequent lifting or flipping.

[0052] In this embodiment, a positioning plate 45 is provided inside the first clamping bracket 1 for positioning the object to be clamped, but not limited thereto. According to requirements, a positioning plate 45 may also be provided inside the second clamping bracket 2, but not limited thereto.

[0053] In this embodiment, the object to be clamped may be a power module, but not limited thereto.

[0054] As an example, the hanging bracket 31 has a U-shaped structure with an opening downward, including a hanging bracket cross beam extending in the horizontal direction and two hanging bracket arms extending downward from both ends of the hanging bracket cross beam. The first clamping bracket 1 and the second clamping bracket 2 are respectively rotatably connected to the lower ends of the two hanging bracket arms. The extending length of the hanging bracket arm is at least greater than half of the width of the clamping bracket to reserve a certain space for the flipping of the clamping bracket.

[0055] Continue to refer to Figure 1 , in this embodiment, the clamping assembly 30 may further include a first driving member 34 for driving the first clamping bracket 1 and the second clamping bracket 2 to approach or separate from each other. As an example, the first driving member 34 may be a telescopic member, which extends substantially along the extending direction of the rotation axis of the clamping bracket relative to the hanging bracket 31 and is connected between the first clamping bracket 1 and the second clamping bracket 2. By the telescoping of the telescopic member, the first clamping bracket 1 and the second clamping bracket 2 can be driven to approach or separate from each other, thereby clamping or releasing the object to be clamped, but not limited thereto.

[0056] As an example, the telescopic member may include a telescopic rod or a lead screw assembly, but not limited thereto.

[0057] Continue to refer to Figure 1 , the first clamping bracket 1 may include a first clamping body 32 and a first guiding frame 36. The first clamping body 32 is rotatably connected to the first end of the hanging bracket 31. For example but not limited to, the middle part in the width direction of the first clamping body 32 is rotatably connected to the first end of the hanging bracket 31. There may be two first guiding frames 36, and the two first guiding frames 36 may be fixedly spaced apart at both ends in the width direction of the first clamping body 32, but not limited thereto. As an example, the two first guiding frames 36 are connected to the first clamping body 32 to form a first clamping bracket 1 having a "匚" - shaped structure.

[0058] Correspondingly, the second clamping bracket 2 includes a second clamping body 33 and a second guiding bracket 37. The middle part of the second clamping body 33 in the width direction is rotatably connected to the second end of the hanging bracket 31. Among them, the second clamping body 33 and the first clamping body 32 can be arranged facing each other, so that when the first clamping bracket 1 and the second clamping bracket 2 approach each other, they can clamp the opposite sides of the object to be clamped, but it is not limited thereto. Further, there may be two second guiding brackets 37, and the two second guiding brackets 37 may be fixedly arranged at intervals at both ends of the second clamping body 33 in the width direction, but it is not limited thereto. As an example, the second clamping body 33 and the two second guiding brackets 37 are connected to form a second clamping bracket 2 with a "C" - shaped structure.

[0059] One end of the first guiding bracket 36 is fixed to the first clamping body 32, and the other end extends towards the second clamping body 33. One end of the second guiding bracket 37 is fixed to the second clamping body 33, and the other end extends towards the first clamping body 32. And the first guiding bracket 36 and the second guiding bracket 37 are arranged in an inserted - connection manner. The inserted - connection means that one of the first guiding bracket 36 and the second guiding bracket 37 forms a slot or a jack, and the other can be inserted into the slot or the jack, so that the first guiding bracket 36 and the second guiding bracket 37 are connected together and can conduct movement guiding when the first clamping bracket 1 and the second clamping bracket 2 approach or move away from each other.

[0060] In this embodiment, both the first clamping bracket 1 and the second clamping bracket 2 are in a "C" - shaped structure, but it is not limited thereto. The openings of the two "C" - shaped structures are arranged opposite to each other to form a clamping bracket with a rectangular frame structure. And both ends of the first driving member 34 are respectively connected to the first guiding bracket 36 and the second guiding bracket 37, so as to drive the first clamping bracket 1 and the second clamping bracket 2 to approach or move away from each other.

[0061] In this embodiment, since the two first guiding brackets 36 are fixed to both ends of the first clamping body 32, and the middle part of the first clamping body 32 in the width direction is rotatably connected to the hanging bracket 31, the first clamping bracket 1 is formed into a structure symmetric with respect to the rotation axis. Correspondingly, the second clamping bracket 2 is formed into a structure symmetric with respect to the rotation axis. Thus, the clamping bracket with a rectangular frame structure is formed into a structure symmetric with respect to the rotation axis, but it is not limited thereto.

[0062] In this embodiment, an example is given where two "C"-shaped structures are inserted into each other to form a clamping frame with a rectangular frame structure, but it is not limited thereto. According to needs, one of the first clamping frame 1 and the second clamping frame 2 has a "C"-shaped structure, and the other forms an "I"-shaped structure. The two opposite arms of the "C"-shaped structure can be inserted into the two ends of the "I"-shaped structure to form a clamping frame with a rectangular frame structure, which is within the protection scope of the present disclosure. In addition, both the first clamping frame 1 and the second clamping frame 2 have an "I"-shaped structure, and the two "I"-shaped structures are arranged facing each other. The ends of the two "I"-shaped structures are respectively connected by a first driving member 34, so that the first clamping frame 1 and the second clamping frame 2 with an "I"-shaped structure and the two first driving members 34 connected between the first clamping frame 1 and the second clamping frame 2 form a clamping frame with a rectangular frame structure, but it is not limited thereto. At this time, the first driving member 34 can be used as the power source for the relative movement of the first clamping frame 1 and the second clamping frame 2, and can also be used as the guide member for the relative movement of the first clamping frame 1 and the second clamping frame 2, but it is not limited thereto.

[0063] Specifically, one of the first guide frame 36 and the second guide frame 37 is provided with first flanges 372 on both sides along the height direction of the clamping frame, and the other is in contact with the inner side surfaces of the first flanges 372 on both sides along the height direction of the clamping frame.

[0064] Refer to Figure 2 , since the structures of the first clamping frame 1 and the second clamping frame 2 are substantially the same, this embodiment will take the second clamping frame 2 as an example for illustration.

[0065] The second guide frame 37 includes a guide frame body 371 and first flanges 372 provided on both sides in the height direction of the guide frame body 371. The two first flanges 372 on the same second guide frame 37 are arranged facing each other. The distance between the two first flanges 372 can be equal to the height dimension of the first guide frame 36 along the height direction of the clamping frame, so that both sides of the first guide frame 36 along the height direction of the clamping frame can be in contact with the two first flanges 372, and the two first flanges 372 limit the first guide frame 36 in the height direction of the clamping frame.

[0066] In this embodiment, an example is given where the cross-section of the second guide frame 37 is formed into a "C" shape to form a slot for the first guide frame 36 to be inserted, but it is not limited thereto.

[0067] Further, the other of the first guide frame 36 and the second guide frame 37 is provided with second flanges on both sides along the height direction of the clamping frame, and the outer side surfaces of the second flanges are in contact with the inner side surfaces of the first flanges.

[0068] In this embodiment, second flanges are provided on both sides of the first guide frame 36 in the height direction to increase the contact area between the first guide frame 36 and the second guide frame 37, but this is not a limitation.

[0069] Referring to the accompanying drawings, in order to prevent the first guide frame 36 and the second guide frame 37 from separating as they move away from each other and to improve the reliability of the clamping frame, in this embodiment, the first guide frame 36 and the second guide frame 37 are respectively provided with limiting grooves 39. The limiting grooves 39 are provided parallel to the extension direction of the rotation axis, and the limiting pins are movably provided in the two limiting grooves 39, but are not limited thereto.

[0070] As an example, the first guide frame 36 is provided with multiple limiting grooves 39, but this is not a limitation. The limiting groove 39 of the second guide frame 37 is provided at a position corresponding to the limiting groove 39 of the first guide frame 36, but this is not a limitation. As an example, the limiting groove 39 can be an oblong hole extending along the extension direction of the rotation axis, but this is not a limitation.

[0071] The above embodiments are illustrated using the example of the first guide frame 36 and the second guide frame 37 respectively having limiting grooves 39, but are not limited thereto. In an optional embodiment, one of the first guide frame 36 and the second guide frame 37 is provided with a limiting groove 39, the limiting groove 39 being arranged parallel to the extension direction of the rotation axis, and the other is provided with a limiting pin that matches the limiting groove 39, the limiting pin being movably disposed within the limiting groove 39.

[0072] Reference Figures 1 to 3 The second clamping body 33 has a pivot mounting hole 331 in the middle of its width direction. The rotating shaft 41 can be connected in the pivot mounting hole 331. The second end of the hanger 31 can be provided with a bearing seat 43. The rotating shaft 41 is rotatably disposed in the mounting hole of the bearing seat 43, so that the clamping frame can rotate relative to the hanger 31 around the rotating shaft 41, but this is not a limitation.

[0073] In fact, the rotating shaft 41 can be fixedly connected to the second clamping body 33, and a bearing can also be provided between the shaft seat 43 and the rotating shaft 41, but this is not a limitation.

[0074] Specifically, the clamping assembly also includes a pin 42 disposed on a rotating shaft 41. The rotating shaft 41 is rotatable about a rotation axis, and the pin 42 is rotatable along with the rotating shaft 41, reciprocating between a first position and a second position. The pin 42 protrudes a predetermined length from the circumferential surface of the rotating shaft 41. The bearing seat 43 has a first stop and a second stop. When the pin 42 is in the first position, it stops at the first stop, and the clamping frame is in a first flip position. When the pin 42 is in the second position, it stops at the second stop, and the clamping frame is in a second flip position. Thus, by cooperating with the stop on the pin 42 and the bearing seat 43, the rotational position of the rotating shaft 41 is limited, thereby limiting the flip position of the clamping frame.

[0075] As an example, the pivot pin 42 may be positioned through and perpendicular to the axis of rotation, but is not limited thereto.

[0076] In this embodiment, the included angle between the first position and the second position can be set according to the angle requirement of the flipping, for example, but not limited to, the included angle between the first position and the second position is 180° so that the part to be flipped can be flipped 180°, but it is not limited to this.

[0077] Continue to refer to Figure 3 Furthermore, the clamping assembly also includes a shock absorber 35, which is sleeved on the rotating shaft 41 and located inside the hanger 31. As an example, the shock absorber 35 can be an elastic element, such as, but not limited to, a spring or a rubber pad, but not limited thereto. This embodiment is described using a spring as an example of the shock absorber 35. The spring can be sleeved on the outside of the rotating shaft 41 and pressed between the clamping frame and the hanger 31. During the movement of the first clamping frame 1 (or the second clamping frame 2) toward the hanger 31, the shock absorber 35 applies a spring force to the first clamping frame 1 (or the second clamping frame 2) in the direction away from the hanger 31 to prevent the clamping frame from directly impacting the hanger 31, but is not limited thereto.

[0078] In another aspect of this disclosure, a flipping fixture is provided, which includes a frame 10, a lifting assembly 20, and a clamping assembly 30. The frame 10 includes a support frame and an extension beam 15 extending horizontally at the upper end of the support frame.

[0079] The lifting assembly 20 includes a lifting frame 21 and a hook. The lifting frame 21 is movably connected to the extension beam 15, and the hook is connected to the lifting frame 21. For example, but not limited to, the lifting device 22 is connected to the lifting frame 21 and can drive the hook to move. The hook can be connected to the lifting device 22 by a connecting rope. The lifting device 22 can adjust the position of the hook by retracting or releasing the rope. When the lifting frame 31 is installed on the hook, the clamping assembly 30 can rise or fall together with the hook, but is not limited thereto.

[0080] In this embodiment, the lifting frame 21 can move on the extension beam 15, which can drive the clamping assembly 30 to move relative to the frame 10, but this is not a limitation.

[0081] Reference Figure 1 and Figure 4 In order to guide the lifting or lowering of the clamping assembly 30, the flipping fixture includes a guide beam 24 and a guide rod 23. The guide beam 24 is fixed to the lifting frame 21 and is provided with a guide hole that matches the guide rod 23. The guide rod 23 is movably inserted into the guide hole in the longitudinal direction and the bottom end of the guide rod 23 is fixed to the lifting frame 31.

[0082] During the up-and-down movement of the hook, the guide rod 23 will move relative to the guide beam 24. By sliding the guide rod 23 in the guide hole, the up-and-down movement of the clamping assembly 30 can be guided, thereby improving the reliability of the flipping fixture and preventing the clamping assembly 30 from shifting or shaking during the rising or falling process, but this is not the limitation.

[0083] As an example, there are two guide rods 23, which are spaced apart on both sides of the extension beam 15 along the extension direction of the rotation axis.

[0084] As an example, to facilitate the installation of the guide rod 23, the top of the hanger 31 is fixedly connected to the bottom crossbeam 25, and the bottom end of the guide rod 23 is fixedly connected to the bottom crossbeam 25, but this is not a limitation.

[0085] Continue to refer to Figure 4 The lifting assembly 20 also includes a rolling element 26, which is rotatably connected to the lifting frame 21. The rolling element 26 rolls on the extension beam 15 along the extension direction of the extension beam 15. By rolling on the extension beam 15, the lifting frame 21 and the extension beam 15 slide in contact, reducing the friction between the lifting frame 21 and the extension beam 15, thereby extending the service life of the lifting frame 21, but not limited thereto.

[0086] As an example, the rolling element 26 rolls on the top surface of the extension beam 15, but is not limited thereto.

[0087] Furthermore, the tilting fixture also includes a second drive component 17, which is connected to the frame 10 and used to drive the lifting frame 21 to move relative to the extension beam 15. As an example, the second drive component 17 can be an electric push rod, a telescopic lever, or a lead screw assembly, but is not limited thereto. One end of the second drive component 17 is fixedly connected to the frame 10, and the telescopic end is connected to the lifting frame 21.

[0088] The frame 10 includes a frame base 11, a support frame, and an extension beam 15. The support frame includes a longitudinal support 12, a diagonal support 13, a first reinforcing rib 14, and a second reinforcing rib 16. The frame base 11 serves as the basic load-bearing component of the entire tilting fixture, ensuring its stability during operation. The bottom end of the longitudinal support 12 is fixed to the frame base 11, and the longitudinal support 12 extends longitudinally. The bottom end of the diagonal support 13 is fixed to the frame base 11. The diagonal support 13 is spaced apart from the longitudinal support 12 and is inclined at a predetermined angle relative to the horizontal plane. The diagonal support 13 and the longitudinal support 12 cooperate to form the main support frame of the frame 10. The first reinforcing rib 14 and the second reinforcing rib 16 connect the longitudinal support 12 and the frame base 11, mainly to improve the structural strength of the frame 10, but are not limited thereto.

[0089] Reference Figure 1 and Figure 4 The hanger 31 is equipped with a hanger handle 40. There can be two hanger handles 40, which are respectively set on two opposite hanger arms of the U-shaped hanger, but this is not a limitation. The operator can push and pull the hanger 31 by grasping the hanger handle 40. When the hanger 31 is connected to the lifting frame 21, the lifting frame 21 can be driven to move relative to the extension beam 15, thereby realizing the position movement of the hanger 31.

[0090] Continue to refer to Figure 1 The clamping frame also includes a clamping frame handle 44, which can be set on the first clamping frame 1. The operator can drive the clamping frame to rotate around the rotation axis by operating the clamping frame handle 44, but is not limited thereto.

[0091] The clamping assembly 30 also includes a cover 38, which covers the outside of the first drive member 34 to prevent operators from accidentally contacting the first drive member 34, thereby improving the reliability of the clamping assembly 30.
