[0035] See also Figure 1 , Figure 1 Schematic diagram of a deep space thread fastening auxiliary clamping device provided in some embodiments of the present application. The present application provides a deep space thread fastening auxiliary clamping device. The deep space thread fastening auxiliary clamping device 100 may include a first clamping arm 1 and a second clamping arm 2.

[0036] The first clamp arm 1 may include a first handle 11 and a first body 12. The first body 12 is connected to one end of the first handle 11. Specifically, the first body 12 is disposed on one side of the first handle 11 and is connected to the first handle 11. The first body 12 and the first handle 11 may be integrally formed parts, and such a configuration may reduce the difficulty of assembling the deep space thread fastening auxiliary clamping device 100. The first body 12 and the first handle 11 may also be separate parts, and such a configuration may facilitate replacement and maintenance of the first body 12 or the first handle 11, and is conducive to improving the maintainability of the deep space thread fastening auxiliary clamping device 100.

[0037] The second clamp arm 2 includes a second handle 21 and a second body 22. The second body 22 can be connected to one end of the second handle 21. Specifically, the second body 22 is disposed on one side of the second handle 21 and is connected to the second handle 21. The second body 22 and the second handle 21 can be integrally formed parts, and such a configuration can reduce the difficulty of assembling the deep space thread fastening auxiliary clamping device 100. The second body 22 and the second handle 21 can also be separate parts, and such a configuration facilitates replacement and maintenance of the second body 22 or the second handle 21, which is conducive to improving the maintainability of the deep space thread fastening auxiliary clamping device 100.

[0038] One end of the second body 22 close to the second handle 21 is rotatably connected to the first body 12. Specifically, the second body 22 is rotatably connected to the first body 12, and the rotation point of the second body 22 and the first body 12 is located at one end of the second body 22 close to the second handle 21. Thus, the second body 22 and the first body 12 can form a rotation pair, so that the second body 22 can be controlled to rotate relative to the first body 12 through the first handle 11 and the second handle 21.

[0039] The first handle 11 and the second handle 21 may be plate-shaped structures, which makes it easier for operators to apply force.

[0040] The second body 22 and the second body 22 enclose an installation space 3. In the length direction of the second clamp arm 2, the installation space 3 may have a first opening 31 and a second opening 32. The first opening 31 may be located at the connection between the second body 22 and the second handle 21, and the aperture of the first opening 31 is larger than the aperture of the second opening 32. Specifically, the first opening 31 and the second opening 32 are located at both ends of the installation space 3. In the length direction of the second clamp arm 2, the first opening 31 is located at an end of the second body 22 close to the second handle 21, and the second opening 32 is located at an end of the second body 22 away from the second handle 21. Thus, the installation space 3 can be connected to the outside through the first opening 31 and the second opening 32.

[0041] The second opening 32 can be used to clamp the fastener 200. Specifically, when the deep space thread fastening auxiliary clamping device 100 clamps the fastener 200, the head of the fastener 200 can be located in the installation space 3, and the rest of the fastener 200 extends out of the installation space 3 through the second opening 32. The clamping and release of the fastener 200 can be controlled by controlling the rotation of the second body 22. The fastener 200 can be a bolt, a screw, etc.

[0042] Thus, the screwdriver can be inserted into the installation space 3 through the first opening 31 to rotate the fastener 200, thereby facilitating the fixing or removal of the fastener 200. At the same time, the method of clamping the fastener 200 of the present application is simple, which is conducive to reducing the manufacturing cost of the deep space thread fastening auxiliary clamping device 100, and can also prevent the fastener 200 from falling off.

[0043] The clamping process of the deep space threaded fastening auxiliary clamping device 100 according to the embodiment of the present application is described below.

[0044] When the fastener 200 needs to be clamped, the second handle 21 is moved toward the first handle 11 to rotate the second body 22 and the first body 12, so that the second opening 32 can be opened. The fastener 200 is placed at the second opening 32, so that the head of the fastener 200 is located in the installation space 3, and the rest of the fastener 200 passes through the second opening 32 and extends out of the installation space 3. Then the second handle 21 is moved away from the first handle 11 to restore the second opening 32 to the initial position, so that the deep space thread fastening auxiliary clamping device 100 can clamp the fastener 200.

[0045] According to the deep space thread fastening auxiliary clamping device 100 of the embodiment of the present application, by making the second body 22 rotatably connected to the first body 12, and making the second body 22 and the first body 12 enclose the installation space 3, the fastener 200 can be clamped through the second opening 32 of the installation space 3, so that the deep space thread fastening auxiliary clamping device 100 can use non-magnetic or low-magnetic materials to make the parts used, thereby avoiding the magnetic influence on the product, which is conducive to improving the versatility of the deep space thread fastening auxiliary clamping device 100. At the same time, it can avoid the surrounding magnetic field from affecting the use of the deep space thread fastening auxiliary clamping device 100, which is conducive to ensuring the stability and accuracy of the operation, and there will be no problem of falling off due to the decrease of adsorption force caused by the disappearance of magnetism. In addition, the setting of the first opening 31 of the installation space 3 can avoid the head of the clamped fastener 200 being blocked, so that the screwdriver can directly extend into the installation space 3 through the first opening 31 to rotate the clamped fastener 200, which is conducive to improving the convenience of operation.

[0046] See also Figure 2-Figure 4 , Figure 2 A schematic diagram of a deep space thread fastening auxiliary clamping device provided in some embodiments of the present application, Figure 3 A schematic diagram of a first clamping arm provided in some embodiments of the present application, Figure 4 Schematic diagram of the second clamping arm provided for some embodiments of the present application. In some embodiments, the first body 12 may have a first groove 121, and the second body 22 may have a second groove 221. The first groove 121 and the second groove 221 enclose an installation space 3, and the orthographic projection of the first groove 121 on the plane where the second groove 221 is located coincides with the second projection. Thus, the first groove 121 and the second groove 221 can be connected to each other, so that the first groove 121 and the second groove 221 can form a complete sleeve structure together, thereby reducing the diameter of the deep space thread fastening auxiliary clamping device 100, so that the deep space thread fastening auxiliary clamping device 100 can better extend into the deep space of the product, and can also extend into a narrower space, thereby helping to improve the versatility of the deep space thread fastening auxiliary clamping device 100. At the same time, when the fastener 200 is disassembled, the installation space 3 does not block the head of the fastener 200, so that the fastener 200 can be accurately and efficiently aligned and clamped. Furthermore, it can be ensured that the fastener 200 will not be skewed during the assembly process, thereby improving the accuracy and reliability of the installation of the fastener 200.

[0047] Please continue reading Figure 2-Figure 4 In some embodiments, the second groove 221 has a rounded corner near the first opening 31. Thus, the smoothness of the rotation of the second body 22 can be ensured.

[0048] Please continue reading Figure 2-Figure 4In some embodiments, a first waist portion 13 may be provided on the side wall of the first body 12. Part of the first opening 31 is located on the first waist portion 13. The first handle 11 is connected to the first waist portion 13 and is located outside the first opening 31. Specifically, the orthographic projection of the first handle 11 on the plane where the first waist portion 13 is located is located outside the first opening 31. In this way, the first handle 11 can be prevented from blocking the first opening 31, so that it is convenient for the screwdriver to extend from the first opening 31 into the installation space 3, which is conducive to improving the convenience of operation.

[0049] Exemplarily, the first waist portion 13 may be formed in a “C” shape, extending from the side wall of the first body 12 in a direction away from the installation space 3 .

[0050] A second waist portion 23 may be provided on the side wall of the second body 22. The rest of the first opening 31 may be located on the second waist portion 23, and the second handle 21 is connected to the second waist portion 23 and is located outside the first opening 31. Specifically, the second waist portion 23 and the first waist portion 13 are located on opposite sides of the accommodating space, and the orthographic projection of the second handle 21 on the plane where the second waist portion 23 is located is located outside the first opening 31. Thus, the second handle 21 can be prevented from blocking the first opening 31, so that it is convenient for the screwdriver to extend from the first opening 31 into the installation space 3, which is conducive to improving the convenience of operation.

[0051] Exemplarily, the second waist portion 23 may also be formed in a “C” shape, extending from the side wall of the second body 22 in a direction away from the installation space 3 .

[0052] Please continue reading Figure 2-Figure 4 In some embodiments, a limiting protrusion 14 may be provided on one side of the first waist portion 13 away from the first opening 31. The limiting protrusion 14 may extend in a direction away from the first opening 31. The surface of the limiting protrusion 14 facing the first opening 31 is a first limiting surface 141. The surface of the second waist portion 23 away from the first opening 31 is a second limiting surface 231. The first limiting surface 141 abuts against the second limiting surface 231. Thus, through the contact between the first limiting surface 141 and the second limiting surface 231, the movement of the second clamping arm 2 can be limited, thereby avoiding misalignment and allowing the first clamping arm 1 and the second clamping arm 2 to be normally assembled.

[0053] For example, the number of the limiting protrusions 14 can be two, and the limiting protrusions 14 are provided on both opposite sides of the first opening 31, then the number of the first limiting surfaces 141 is two, and the second waist portion 23 can have the same number of second limiting surfaces 231 as the first limiting surfaces 141. This arrangement can better limit the movement of the second clamping arm 2.

[0054] Please continue reading Figure 2-Figure 4In some embodiments, the deep space thread fastening auxiliary clamping device 100 may further include a rotating shaft 4. A rotating bracket 15 may be provided on the side of the limiting protrusion 14 away from the first waist 13. The rotating bracket 15 may be provided with a first rotating hole 151, and the second waist 23 may be provided with a second rotating hole 232 that matches the first rotating hole 151. The rotating shaft 4 is penetrated by the first rotating hole 151 and the second rotating hole 232. As a result, the second body 22 can rotate around the rotating shaft 4 within a certain angle range, so that the deep space thread fastening auxiliary clamping device 100 can clamp or release the fastener 200, and the structure is simple, which is conducive to reducing the assembly difficulty of the deep space thread fastening auxiliary clamping device 100.

[0055] Exemplarily, a rotating bracket 15 is provided on both opposite sides of the first opening 31, the second waist 23 is located between the two rotating brackets 15, and the second rotating hole 232 on the second waist 23 is opposite to the first rotating hole 151 of the rotating bracket 15, and the rotating shaft 4 passes through the first rotating hole 151 and the second rotating hole 232.

[0056] Please continue reading Figure 2-Figure 4 In some embodiments, the deep space threaded fastening auxiliary clamping device 100 may further include a cotter pin 42. In the length direction of the rotating shaft 4, a limit piece 41 is provided at one end of the rotating shaft 4, and a through hole 43 is provided at the other end. The cotter pin 42 passes through the through hole 43. Specifically, the size of the limit piece 41 may be larger than the size of the first rotating hole 151, so as to avoid falling off from the side with the limit piece 41. The through hole 43 passes through the rotating shaft 4, and the limit pin passes through the through hole 43, so as to avoid falling off from the side with the through hole 43. By providing the limit piece 41 and the cotter pin 42, it is possible to avoid the rotating shaft 4 from falling off during the rotation process, which is beneficial to improve the stability and reliability of the clamping of the deep space threaded fastening auxiliary clamping device 100.

[0057] Please continue reading Figure 2-Figure 4 In some embodiments, the deep space thread fastening auxiliary clamping device 100 may further include a torsion spring 5. The torsion spring 5 is sleeved on the rotating shaft 4, one end of the torsion spring 5 abuts against the first clamping arm 1, and the other end abuts against the second clamping arm 2. As a result, the first body 12 and the second body 22 can form a rotational torque around the rotating shaft 4, and the torque can naturally close the ends of the first body 12 and the second body 22 close to the second opening 32, so that only when the second handle 21 moves toward the first handle 11, the second body 22 can rotate relative to the first body 12, so that the deep space thread fastening auxiliary clamping device 100 can clamp the fastener 200, and further the deep space thread fastening auxiliary clamping device 100 can have a normally closed function.

[0058] Please continue reading Figure 2-Figure 4In some embodiments, the torsion spring 5 may include a first torsion spring 51 and a second torsion spring 52. The first torsion spring 51 and the second torsion spring 52 are both sleeved on the rotating shaft 4 and are located on opposite sides of the second waist 23. The first torsion spring 51 may be a left-handed torsion spring, and the second torsion spring 52 may be a right-handed torsion spring. Thus, the bending moment caused by a single torsion spring can be eliminated, and the misalignment between the first clamp arm 1 and the second clamp arm 2 can be avoided, so that the first clamp arm 1 and the second clamp arm 2 can rotate more smoothly relative to the rotating shaft 4, which is conducive to improving the stability and reliability of the deep space thread fastening auxiliary clamping device 100.

[0059] Please continue reading Figure 2-Figure 4 In some embodiments, the surface of the limiting protrusion 14 facing the second clamping arm 2 can be a support surface 142. The second waist 23 and the second handle 21 can surround a mounting notch 233, and the torsion spring 5 is arranged at the mounting notch 233. This arrangement facilitates the installation of the torsion spring 5, which is conducive to reducing the difficulty of assembling the deep space thread fastening auxiliary clamping device 100.

[0060] One end of the torsion spring 5 abuts against the support surface 142, and the other end abuts against the second handle 21. Therefore, when the clamped fastener 200 needs to be released, the first handle 11 and the second handle 21 are exerted with opposing forces to overcome the torque of the torsion spring 5, so that the second body 22 and the first body 12 can rotate around the rotation axis 4 at a certain angle.

[0061] See also Figure 5-Figure 6 , Figure 5 A schematic diagram of a deep space thread fastening auxiliary clamping device clamping a fastener provided in some embodiments of the present application, Figure 6 Schematic diagram of releasing a fastener from a deep space thread fastening auxiliary clamping device provided in some embodiments of the present application. The tightening process and the disassembly process of the fastener 200 are described below.

[0062] During the tightening process, when the second handle 21 moves toward the direction close to the first handle 11, the second body 22 rotates toward the direction away from the first body 12, and the fastener 200 is placed in the installation space 3, and then the first handle 11 and the second handle 21 are released. Under the action of the torque of the torsion spring 5, the second body 22 rotates toward the direction close to the first body 12, and the fastener 200 can be clamped. At this time, the deep space thread fastening auxiliary clamping device 100 can be held, the fastener 200 is aligned with the threaded hole on the product, and then the screwdriver is extended into the installation space 3 from the first opening 31, and inserted into the groove of the head of the fastener 200, and the fastener 200 is selected into the threaded hole. Before the fastener 200 is completely tightened, the second handle 21 is moved toward the direction close to the first handle 11, so that the deep space thread fastening auxiliary clamping device 100 releases the fastener 200, and finally the screwdriver is continued to be used to tighten the fastener 200.

[0063] During the disassembly process, first use a screwdriver to loosen the fastener 200 to a certain extent, and then extend the deep space thread fastening auxiliary clamping device 100 into the deep space. Then move the second handle 21 toward the first handle 11 so that part of the fastener 200 can pass through the second opening 32 and extend into the installation space 3, and then loosen the second handle 21 to allow the deep space thread fastening auxiliary clamping device 100 to clamp the fastener 200. Then use a screwdriver to completely unscrew the fastener 200, and finally use the deep space thread fastening auxiliary clamping device 100 to take the fastener 200 out of the deep space.

[0064] See also Figure 7 , Figure 7 Schematic diagram of the deep space threaded fastening auxiliary clamping device and the instrument equipment provided for some embodiments of the present application. For example, when the part of the product structure where the fastener 200 needs to be installed is located on the inner plate of the product, the cover plate 300 blocks the threaded fastening operation, so that the fastener 200 cannot be directly sent to the position where it needs to be fastened. Therefore, an operating hole can be directly opened on the cover plate 300 at a position opposite to the threaded hole, and then the deep space threaded fastening auxiliary clamping device 100 is used to send the fastener 200 to the fastening position, which is conducive to simplifying the product structure design, reducing product design costs, and shortening the product development cycle.

[0065] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0066] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
