Description

Technical Field

[0001] This utility model belongs to the field of fastener assembly technology, specifically relating to an installation tool for self-locking screws. Background Technology

[0002] In aerospace and other fields, different installation environments and locations place varying requirements on fasteners. Some require high tensile strength, others high fatigue resistance, and still others excellent anti-loosening properties. These different performance requirements not only impose high demands on the structural form and dimensional accuracy of fasteners but also impose strict requirements on the fastener installation process. Only when the fastener and the mounting hole achieve an optimal match can the performance of the connection pair meet the design requirements.

[0003] Self-locking screws are a type of fastener. Their thin, open-end self-locking structure deforms locally during installation, causing it to open outwards. The opened blades then lock into the other end of the threaded part of the mounting hole, significantly increasing the anti-loosening effect. To meet the installation requirements of self-locking screws, the installation tools should enable quick and easy installation, avoiding malfunctions due to cumbersome procedures and reducing operational risks.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other.

[0031] like Figure 1 , Figure 2 , Figure 3 The present invention is shown as an embodiment of the present invention. This embodiment discloses an installation tool for a self-locking screw, including a support frame 1. A wrench 2 and a push-opening part 3 are movably connected on the support frame 1. The push-opening part 3 is coaxially disposed below the wrench 2. The wrench 2 is used to control the rotation of the self-locking screw, and the push-opening part 3 is used to push open the self-locking flower structure at the bottom of the self-locking screw.

[0032] In one embodiment, such as Figure 1 , Figure 2 As shown, the wrench part 2 includes a wrench screw 21, a wrench sleeve 22, and a wrench groove 23. The wrench screw 21 is vertically threaded onto the support frame 1. The wrench sleeve 22 is detachably connected to the bottom of the wrench screw 21. The wrench groove 23 is located at the bottom of the wrench sleeve 22 and is used to engage with the nut of the self-locking screw.

[0033] By engaging the wrench slot 23 with the nut of the self-locking screw and then rotating the wrench screw 21, the rotation of the wrench sleeve 22 can be controlled. Since the wrench sleeve 22 is detachable, different sizes of wrench sleeves 22 can be replaced to accommodate different types of self-locking screws, thereby improving the adaptability of the installation tool.

[0034] In one embodiment, such as Figure 1 , Figure 2 As shown, a rectangular positioning block 24 is fixedly connected to the bottom of the wrench screw 21, and a positioning groove 25 is provided on the top of the wrench sleeve 22 for the positioning block 24 to be tightly inserted. A locking screw 26 is threadedly connected to the wrench sleeve 22, and a locking groove 27 is provided on the positioning block 24 for the locking screw 26 to be threadedly engaged, so that the wrench sleeve 22 can be quickly replaced.

[0035] In one embodiment, such as Figure 1 , Figure 2 As shown, the wrench 21 includes a wrench nut 211 and a wrench rod 212. The wrench nut 211 is integrally formed and connected to the top of the wrench rod 212. The wrench sleeve 22 is detachably connected to the bottom of the wrench rod 212. The top of the wrench nut 211 is provided with a control groove 213 for external hex wrench to facilitate the operator to control the wrench 21 to rotate quickly.

[0036] In one embodiment, such as Figure 1 , Figure 3 As shown, the opening part 3 includes an opening screw 31, an opening nut 32, and a control groove 33. The opening screw 31 is vertically threaded onto the support frame 1. The opening nut 32 is integrally formed and connected to the bottom of the opening screw 31. The control groove 33 is located at the bottom of the opening nut 32 and is used for external hex wrench engagement. By controlling the opening nut 32 with the external hex wrench, the opening screw 31 is rotated, and then the top of the opening screw 31 can open the self-locking structure at the tail of the self-locking screw.

[0037] In one embodiment, such as Figure 1 , Figure 3 As shown, the top of the opening screw 31 is provided with an opening conical surface 34 to improve the guiding and opening effect, so that the opening conical surface 34 can smoothly open the self-locking opening structure at the bottom of the self-locking screw. At the same time, a limiting sleeve 35 is movably sleeved on the opening screw 31. The limiting sleeve 35 is located between the support frame 1 and the opening nut 32 to limit the opening stroke of the opening screw 31.

[0038] In one embodiment, such as Figure 1As shown, the support frame 1 is C-shaped, and a handle hole 4 is provided through the middle of the support frame 1 to facilitate the operator's grip on the support frame 1. Two weight-reducing holes 5 are provided through the support frame 1, and the two weight-reducing holes 5 are symmetrically distributed on both sides of the handle hole 4 to reduce the weight of the support frame 1.

[0039] In one embodiment, such as Figure 1 As shown, the inner side of the support frame 1 is provided with an arc-shaped positioning surface 6. The positioning surface 6 is used to tightly abut against the external installation body to realize the positioning of the support frame 1, thereby facilitating the installation operation of the self-locking screws by the staff.

[0040] The installation tool for the self-locking screw in this embodiment is used as follows:

[0041] Select the appropriate wrench 22 and limit sleeve 35 according to the specifications of the self-locking screw, and install the wrench 22 and limit sleeve 35. Then, use a hex wrench to control the wrench screw 21 to drive the wrench sleeve 22 to rotate until the self-locking screw is tightened. Next, use a hex wrench to control the opening nut 32 to drive the opening screw 31 to rotate. When the limit sleeve 35 abuts against the support frame 1, the opening cone surface 34 opens the opening self-locking structure at the tail of the self-locking screw, thereby completing the assembly of the self-locking screw. Then the installation tools can be disassembled.

[0042] As can be seen from the above, this installation tool can easily open the self-locking structure at the tail of the self-locking screw, causing the tail to deform and thus achieving an anti-loosening effect, improving the installation efficiency and accuracy of the self-locking screw. Furthermore, the installation tool has a simple structure and the method is easy to implement.
