[0033] When non-magnetic or weakly magnetic bolts need to be assembled in narrow gaps between compactly arranged equipment or components, the bolts are difficult to assemble due to the limited space and the inability to use magnetic socket tools.

[0034] In order to at least solve the problem that bolts are difficult to assemble when the space is small and the magnetic socket tool cannot be used, an embodiment of the present application proposes an assembly device 100 that can clamp the bolts to reduce the difficulty of assembling the bolts in a small space.

[0035] The assembly device 100 according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0036] Figure 1 is a schematic diagram of an assembly device according to an embodiment of the present application, wherein the clamping member is in a clamping position; Figure 2 A partial cross-sectional view of an assembly device according to an embodiment of the present application; Figure 3 A partial cross-sectional view of another portion of the assembly device according to an embodiment of the present application; Figure 4 This is a schematic diagram of the assembly device according to an embodiment of the present application from another angle, wherein the clamping member is located in a separated position.

[0037] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the present application proposes an assembly device 100, comprising a sleeve assembly 10, a clamping member 20, and a trigger assembly 30. The sleeve assembly 10 comprises a main sleeve 11 and a screwing sleeve 12, which are connected to each other. The main sleeve 11 is sleeved on the outside of the screwing sleeve 12. The screwing sleeve 12 is adapted to be embedded in a nut 220 of a bolt 200 and used to screw the bolt 200. The clamping member 20 comprises a main body 21 and a clamping portion 22, which are connected to each other. The main body 21 is rotatably mounted on the main sleeve 11. The clamping member 20 has a clamping position and a separation position relative to the screwing sleeve 12. When the clamping member 20 is in the clamping position, the clamping portion 22 is arranged opposite to the screwing sleeve 12 in the axial direction of the main sleeve 11, and together with the screwing sleeve 12, clamps the nut 220 along the axial direction of the main sleeve 11. The trigger assembly 30 is movably disposed on the main sleeve 11 . The trigger assembly 30 is connected to the main body 21 and is capable of driving the clamping member 20 to move between a clamping position and a separation position.

[0038] It can be understood that the clamping portion 22 located at the separation position is released from its relative arrangement with the screw sleeve 12 in the axial direction of the main sleeve 11 .

[0039] As some examples, the axial direction of the main sleeve 11 is as follows: Figure 1 、 Figure 2 and Figure 3 As indicated by the arrow at a.

[0040] like Figure 4 As shown, when preparing to assemble the bolt 200, the position of the trigger assembly 30 is adjusted so that the clamping member 20 is located in the separation position. In the axial direction of the main sleeve 11, the clamping member 20 located in the separation position is released from the relative position with the screwing sleeve 12. As a result, the clamping portion 22 can avoid obstructing the bolt 200, so that the nut 220 of the bolt 200 can be smoothly embedded in the screwing sleeve 12.

[0041] Combine Figure 1 、 Figure 2 and Figure 3As shown, when the nut 220 is embedded in the screwing sleeve 12, the position of the trigger assembly 30 is adjusted so that the clamping member 20 is in the clamping position. In the axial direction of the main sleeve 11, when the clamping member 20 is in the clamping position, the clamping portion 22 is arranged relative to the screwing sleeve 12, and is suitable for abutting against the nut 220 embedded in the screwing sleeve 12 in the axial direction of the main sleeve 11. As a result, the clamping portion 22 can limit the nut 220 from disengaging from the screwing sleeve 12 in the axial direction of the main sleeve 11, thereby achieving clamping of the bolt 200.

[0042] It should be noted that the nut 220 is embedded in the screw sleeve 12 , and either a portion of the nut 220 is embedded in the screw sleeve 12 , or the entire nut 220 is embedded in the screw sleeve 12 .

[0043] After the clamping portion 22 clamps the bolt 200, the bolt 200 is aligned with the threaded hole to be assembled, and the main sleeve 11 is rotated, thereby rotating the screw sleeve 12 to screw the bolt 200 into the threaded hole. After the bolt 200 is screwed, the trigger assembly 30 is adjusted to the disengaged position of the clamping portion 22, moving the main sleeve 11 away from the bolt 200, thereby separating the screw sleeve 12 from the bolt 200.

[0044] It is understandable that those skilled in the art may choose to fully screw the bolt 200 into the threaded hole according to actual conditions, thereby fully tightening the bolt 200, or may choose to partially screw the bolt 200 into the threaded hole and then tighten the bolt 200 using other tools (such as a wrench).

[0045] The assembly device 100 of the embodiment of the present application can clamp and release the bolt 200 through the cooperation between the clamping portion 22 and the screwing sleeve 12, thereby reducing the difficulty of assembling the bolt 200 in a narrow space.

[0046] In addition, the clamping portion 22 constrains the bolt 200 in the axial direction of the main sleeve 11, and the screwing sleeve 12 applies torque to the bolt 200 in the circumferential direction of the bolt 200, thereby making the constraining force of the clamping portion 22 and the torque of the screwing sleeve 12 not interfere with each other, that is, the clamping portion 22 does not participate in the torque transmission, and the screwing sleeve 12 does not need to take into account the clamping force, thereby avoiding the mutual consumption of the constraining force of the clamping portion 22 and the torque of the screwing sleeve 12, so that when the clamping portion 22 efficiently and stably clamps the bolt, the screwing sleeve 12 can maintain a high screwing efficiency and a high screwing reliability.

[0047] Combine Figure 1 、 Figure 3 and Figure 4As shown, in some embodiments, the assembly device 100 includes a plurality of clamping members 20. The trigger assembly 30 is connected to the main body 21 of each clamping member 20 and is used to drive the clamping portions 22 of each clamping member 20 to operate in groups. The clamping portions 22 of the plurality of clamping members 20 are collectively used to clamp the screw 210 of the bolt 200 along the radial direction of the main sleeve 11. In other words, the plurality of clamping portions 22 are suitable for clamping the screw 210 of the bolt 200.

[0048] The trigger assembly 30 drives the clamping portion 22 of each clamping member 20 to move in groups, which means that the trigger assembly 30 drives the clamping members 20 to move synchronously or approximately synchronously. Thus, the clamping members 20 can be controlled in batches through the trigger assembly 30, thereby increasing the adjustment efficiency of the clamping portion 22.

[0049] When the clamping member 20 is in the clamping position, the clamping portion 22 is adapted to abut against the nut 220 embedded in the screw sleeve 12 in the axial direction of the main sleeve 11. Thus, the clamping portion 22 can constrain the bolt 200 in the axial direction of the screw rod 210. When each clamping member 20 is in the clamping position, the clamping portions 22 of the plurality of clamping members 20 are collectively used to clamp the screw rod 210 of the bolt 200 in the radial direction of the main sleeve 11. Thus, the clamping portions 22 can constrain the bolt 200 in the radial direction of the screw rod 210.

[0050] The radial and axial clamping effect of the clamping portion 22 on the bolt 200 can reduce the probability of axial movement of the bolt 200 and the probability of swinging, skewing and shaking of the screw rod 210 of the bolt 200, so that the clamping portion 22 can increase the positioning effect of the bolt 200.

[0051] Combine Figure 1 、 Figure 3 and Figure 4 As shown, in some embodiments, the trigger assembly 30 includes a trigger member 31 and a plurality of connecting rods 32. The trigger member 31 is arranged on the outside of the main sleeve 11 in a manner that it can move along the axial direction of the main sleeve 11. The plurality of connecting rods 32 are arranged in a one-to-one correspondence with the plurality of clamping members 20. One end of each connecting rod 32 is hinged to the trigger member 31, and the other end of each connecting rod 32 is hinged to the main body 21.

[0052] The movement of the trigger member 31 in the axial direction of the main sleeve 11 can pull the main body 21 to move via the connecting rod 32. Multiple clamping members 20 are connected to the same trigger member 31 via the connecting rod 32. When the trigger member 31 moves in the axial direction of the main sleeve 11, the connecting rod 32 synchronously pulls all clamping members 20, causing the clamping members 20 to switch between the clamping position and the disengaged position as a group. This reduces the probability of uneven force on the bolt 200 caused by the independent movement of a single clamping member 20, thereby increasing the stability of the clamping of the bolt 200. Furthermore, when the trigger member 31 moves in the axial direction of the main sleeve 11, the connecting rod 32 synchronously pulls all main bodies 21, which can also simplify the operation process and increase the efficiency of controlling the clamping members 22.

[0053] By providing the connecting rod 32 , the operator can control the position of the clamp 20 at a position farther away from the clamp 20 , thereby enabling the operator to adjust the position of the clamp 20 outside a narrow space, thereby reducing the difficulty of assembling the bolt 200 .

[0054] The two ends of the connecting rod 32 are hinged to avoid motion interference caused by a rigid connection, so that the structural setting of the assembly device 100 of this embodiment is more reasonable.

[0055] The trigger member 31 and the connecting rod 32 both move in the axial direction of the main sleeve 11, while the torque of the main sleeve 11 driving the screwing sleeve 12 is transmitted circumferentially around the main sleeve 11. The movement directions of the trigger member 31 and the connecting rod 32 are independent of the movement direction of the screwing sleeve 12, thereby preventing the clamping action and the screwing process from interfering with each other.

[0056] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the trigger assembly 30 further includes a trigger nut 33 and an elastic member 34. The trigger nut 33 is threadedly connected to the main sleeve 11 and is configured to be able to move in the axial direction of the main sleeve 11 when rotated. The main sleeve 11 is provided with a first boss 111. The trigger member 31 is located between the first boss 111 and the trigger nut 33. A second boss 311 is provided at one end of the trigger member 31. The elastic member 34 is stopped between the first boss 111 and the second boss 311. The elastic member 34 is in a compressed state. The trigger member 31 abuts against the trigger nut 33 under the elastic force of the elastic member 34.

[0057] Twisting the trigger nut 33 causes it to rotate in the axial direction of the main sleeve 11. When the trigger nut 33 moves toward the first boss 111, the trigger member 31 abuts against the trigger nut 33, pushing the trigger member 31 along the main sleeve 11 toward the first boss 111. When the trigger nut 33 moves away from the first boss 111, the trigger member 31, driven by the elastic member 34, also moves away from the first boss 111. Thus, through the coordinated action of the trigger nut 33 and the elastic member 34, the position of the elastic member 34 can be adjusted by controlling the trigger nut 33, thereby reducing the difficulty of controlling the elastic member 34.

[0058] When the trigger nut 33 rotates, it can generate movement in the axial direction of the main sleeve 11. By adjusting the rotation angle of the trigger nut 33, the position of the trigger nut 33 can be accurately adjusted, thereby accurately adjusting the position of the trigger member 31, and then the position of the clamping portion 22 can be accurately adjusted.

[0059] Since the thread pair has a self-locking function, the position of the trigger nut 33 can be maintained after adjustment, thereby reducing the probability of the trigger nut 33 moving outside the axial direction of the main sleeve 11, thereby increasing the stability of the clamping part 22 clamping the bolt 200.

[0060] The first boss 111 and the second boss 311 provide a position limit for the elastic member 34 along the axial direction of the main sleeve 11, thereby enabling the elastic force of the elastic member 34 to be transmitted along the axial direction of the main sleeve 11. The first boss 111 and the second boss 311 can reduce the probability of the elastic member 34 deflecting or bending, thereby improving the efficiency and stability of the elastic force transmission.

[0061] Combine Figure 1 、 Figure 3 and Figure 4 As shown, in some embodiments, the axial direction of the trigger member 31 is consistent with the axial direction of the main sleeve 11 , and the trigger member 31 and the elastic member 34 are both sleeved on the main sleeve 11 .

[0062] The axial direction of the trigger member 31 is consistent with the axial direction of the main sleeve 11 . The trigger member 31 is sleeved on the main sleeve 11 , so that the trigger member 31 can be stably installed on the main sleeve 11 when it has a large length.

[0063] The trigger member 31 is sleeved on the main sleeve 11 , and the main sleeve 11 can provide a higher guiding capability for the trigger member 31 , thereby improving the movement accuracy of the main sleeve 11 .

[0064] The trigger member 31 is sleeved on the main sleeve 11 . In the radial direction of the trigger member 31 , the main sleeve 11 can provide continuous support for the trigger member 31 , thereby increasing the anti-bending ability of the trigger member 31 .

[0065] The elastic member 34 is sleeved on the main sleeve 11. In the radial direction of the trigger member 31, the main sleeve 11 can provide support and guidance for the elastic member 34, thereby reducing the probability of the elastic member 34 offset in the inward and outward directions of the trigger member 31, thereby increasing the accuracy of the movement of the elastic member 34 and increasing the probability of abnormal deformation of the elastic member 34.

[0066] The trigger member 31 and the elastic member 34 are both sleeved on the main sleeve 11, thereby avoiding the need to design additional structures to install the trigger member 31 and the elastic member 34, thereby increasing the space utilization of the assembly device 100 of this embodiment, and making the structure of the assembly device 100 of this embodiment more compact.

[0067] As some examples, the elastic member 34 is a spring.

[0068] In other embodiments, the main sleeve 11 is provided with a slide groove, the length direction of the slide groove is consistent with the axial direction of the main sleeve 11 , the trigger member 31 is slidably disposed in the slide groove, and the elastic member 34 is sleeved on the main sleeve 11 .

[0069] The sliding groove structure can guide the movement of the trigger member 31, making the movement of the trigger member 31 more precise.

[0070] Combine Figure 1 and Figure 3 As shown, in some embodiments, when the clamping portion 22 of each clamping member 20 is in the clamping position, in the circumferential direction of the main sleeve 11, the main body portions 21 of any two adjacent clamping members 20 abut against each other, in the radial direction of the main sleeve 11, the main body portions 21 are covered on the outside of the screwing sleeve 12, and in the axial direction of the main sleeve 11, the clamping portion 22 is covered on the end of the screwing sleeve 12.

[0071] When each clamping member 20 is in the clamping position, in the circumferential direction of the screw sleeve 12, the main bodies 21 of the two adjacent clamping members 20 abut against each other. Through the abutment between the main bodies 21, each clamping portion 22 can be more accurately in the clamping position, thereby improving the clamping effect of the clamping portion 22.

[0072] When each clamping member 20 is in the clamping position, the main body 21 covers the outside of the screw sleeve 12 in the radial direction of the main sleeve 11. When each clamping member 20 is in the clamping position, the clamping portion 22 covers the screw sleeve 12 in the axial direction of the main sleeve 11. The main body 21 and the clamping portion 22 can protect the screw sleeve 12 from all directions, thereby reducing the probability of external force damage to the screw sleeve 12 when screwing the bolt 200. Moreover, the positioning of the clamping portion 22 and the main body 21 in this embodiment can increase space utilization, which is conducive to the miniaturization of the assembly device 100 of this embodiment.

[0073] Combine Figure 1 and Figure 3 As shown, in some optional embodiments, when each clamping member 20 is located at the clamping position, the clamping portions 22 of any two adjacent clamping members 20 abut against each other in the circumferential direction of the main sleeve 11 .

[0074] When each clamping member 20 is in the clamping position, the clamping portions 22 of any two adjacent clamping members 20 abut against each other in the circumferential direction of the main sleeve 11, thereby increasing the contact area between the clamping portion 22 and the bolt 200, thereby increasing the stability of the clamping bolt 200.

[0075] Through the abutment between the clamping parts 22 , each clamping part 22 can be further positioned at a clamping position more accurately, thereby further improving the clamping effect of the clamping parts 22 .

[0076] When each clamping member 20 is in the clamping position, the clamping portions 22 of any two adjacent clamping members 20 abut against each other in the circumferential direction of the main sleeve 11, thereby further increasing the protective effect of the clamping portions 22 on the screwing sleeve 12, and further reducing the probability of the screwing sleeve 12 being damaged by external forces.

[0077] Combine Figure 1 and Figure 3 As shown, in some optional embodiments, when each clamping member 20 is in the clamping position, all the clamping members 20 form a cylindrical structure, wherein the outer wall surfaces of the main body portions 21 of all the clamping members 20 are arc-shaped and constitute the side surfaces of the cylindrical structure, and the outer wall surfaces of the clamping portions 22 of all the clamping members 20 are planar and constitute the bottom surfaces of the cylindrical structure.

[0078] When each clamping member 20 is located at the clamping position, all the clamping members 20 form a cylindrical structure, so that the clamping members 20 and the screw sleeve 12 have a high adaptability, thereby further improving space utilization.

[0079] When each clamping member 20 is located at the clamping position, all the clamping members 20 form a cylindrical structure, so that the clamping members 20 have a lower moment of inertia, so that the assembly device 100 of this embodiment can be suitable for high-speed rotation usage scenarios.

[0080] Combine Figure 1 and Figure 4 As shown, in some embodiments, the assembly device 100 further includes a mounting screw 40, the number of the plurality of clamping members 20 is two, and the clamping member 20 further includes a connecting portion 23. The connecting portion 23 is located on a side of the main body 21 away from the clamping portion 22 and is connected to the clamping portion 22. The connecting portions 23 of the two clamping members 20 are stacked in the radial direction of the main sleeve 11, that is, a stacked structure is formed between the connecting portions 23 of the two clamping members 20. The mounting screws 40 are sequentially inserted through the connecting portions 23 of the two clamping members 20 and connected to the main sleeve 11. The connecting portion 23 is configured to be pivotable about the mounting screw 40.

[0081] The connecting parts 23 of the two clamping members 20 are stacked in the radial direction of the main sleeve 11, so that the connecting part 23 of one clamping member 20 is located on one side of the connecting part 23 of the other clamping member 20, which can avoid the two connecting parts 23 from interfering with each other during rotation, thereby increasing the rationality of the structure.

[0082] The mounting screw 40 can mount the connecting portion 23 and provide a pivot for the rotation of the connecting portion 23 , thereby further increasing space utilization.

[0083] When the connecting portion 23 needs to be installed or removed, it is only necessary to install or remove the mounting screw 40 , thereby reducing the difficulty of installing or removing the clamping member 20 .

[0084] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the main sleeve 11 defines a mounting cavity 112, the axial direction of the mounting cavity 112 being consistent with the axial direction of the main sleeve 11. A portion of the screwing sleeve 12 is connected to the main sleeve 11 and is located in the mounting cavity 112, while another portion of the screwing sleeve 12 is disposed outside the main sleeve 11 and is adapted to be embedded in the nut 220 of the bolt 200. In other words, a portion of the screwing sleeve 12 is embedded in the mounting cavity 112, while another portion of the screwing sleeve 12 extends out of the mounting cavity 112.

[0085] The screw sleeve 12 can be stably installed through the installation cavity 112 , thereby reducing the probability of the screw sleeve 12 being separated from the main sleeve 11 .

[0086] Combine Figure 1 and Figure 4As shown, in some embodiments, the sleeve assembly 10 further includes an extension rod 13, the axial direction of the extension rod 13 being consistent with the axial direction of the main sleeve 11. A portion of the extension rod 13 is located in the installation cavity 112 and connected to the screwing sleeve 12, while another portion of the extension rod 13 is located outside the installation cavity 112 and is suitable for connecting to a wrench. The wrench can be an adjustable wrench, a fixed wrench, an electric wrench, etc.

[0087] By providing the extension rod 13 , the operator can indirectly rotate the screw sleeve 12 at a distance from the screw sleeve 12 , thereby enabling the operator to rotate the screw sleeve 12 outside a narrow space, thereby reducing the difficulty of assembling the bolt 200 .

[0088] In some embodiments, the screwing sleeve 12 is configured as a rubber member, and the screwing sleeve 12 is adapted to have an interference fit with the nut 220 .

[0089] When the screw sleeve 12 and the nut 220 are interference fit, the rubber inner wall of the screw sleeve 12 will squeeze the nut 220, thereby increasing the friction between the nut 220 and the screw sleeve 12, thereby making the bolt 200 more firmly fit with the screw sleeve 12.

[0090] In addition, the rubber member has a relatively large static friction coefficient, thereby further increasing the stability of the fit between the screw sleeve 12 and the bolt 200 .

[0091] In some embodiments, a rubber piece is disposed in the screw sleeve 12 . The rubber piece is suitable for being sleeved on the nut 220 and having an interference fit with the nut 220 .

[0092] When the screw sleeve 12 and the nut 220 are interference fit, the inner wall of the rubber lining will squeeze the nut 220, thereby increasing the friction between the nut 220 and the screw sleeve 12, thereby making the bolt 200 more firmly fit with the screw sleeve 12.

[0093] In addition, the rubber member has a relatively large static friction coefficient, thereby further increasing the stability of the fit between the screw sleeve 12 and the bolt 200.

[0094] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
