Furthermore, the structure is simple, easy to operate and use, and suitable for widespread application.

Description

Technical Field

[0001] This utility model belongs to the field of fixed tooling, and in particular relates to a screw fixing auxiliary device. Background Technology

[0002] In communication equipment, for connection terminals (such as aviation connectors), not only is the connection reliability of the slotted screw required, but also the uniformity of the slot direction is required.

[0003] In the current assembly process, alignment is mainly achieved through the experience and repeated adjustments of operators, lacking effective tooling or guiding devices for standardized positioning. This existing approach has the following problems: firstly, repeated manual confirmation of the installation direction significantly increases the assembly time for individual parts, reducing overall efficiency; secondly, relying entirely on human experience easily leads to poor groove alignment consistency, affecting connection quality and appearance uniformity, thus creating potential reliability and aesthetic risks. Summary of the Invention

[0004] The present invention aims to solve the above problems and provide a screw fixing auxiliary device that can help align the groove direction of the aviation screw during the installation process.

[0005] The screw fixing auxiliary device of this utility model includes a base and a positioning block; the positioning block is disposed on the positioning block; a limiting boss is provided on the top of the positioning block. By setting the limiting boss, the screw is engaged with the groove of the end of the screw to be positioned during screw fixing, thereby positioning the screw and ensuring that the position and direction of the groove of the screw end meet the requirements.

[0006] Furthermore, in the screw fixing auxiliary device of this utility model, a sliding groove is provided on the base; the aforementioned positioning block is disposed within the aforementioned sliding groove. Disposing the positioning block within the sliding groove improves the stability of the positioning block and enhances the positioning effect; it also provides a relatively flat operating surface on the upper end of the base, facilitating the placement of the screw to be positioned and improving operating efficiency.

[0007] Furthermore, in the screw fixing auxiliary device of this utility model, a plurality of positioning blocks are arranged in the sliding groove. This allows for simultaneous positioning of multiple screws requiring positioning, improving positioning efficiency; it also supports flexible adjustment of screw spacing, meeting the assembly requirements of different types of products and exhibiting strong adaptability.

[0008] Furthermore, in the screw fixing auxiliary device of this utility model, a strip-shaped through hole is provided at the bottom of the sliding groove; a fixing threaded hole is provided at the bottom of the positioning block; the positioning block is connected to the base through the strip-shaped through hole by a fastening screw. Fixing the positioning block to the base improves stability and thus improves the positioning effect of the screw to be positioned.

[0009] Furthermore, in the screw fixing auxiliary device of this utility model, the limiting boss is in the shape of a straight line, triangle, quadrilateral, or hexagon. By changing the shape of the limiting boss, this auxiliary device can be adapted to the installation of various screws with different ends.

[0010] The screw fixing auxiliary device described in this utility model, by setting a base and positioning block, can significantly improve assembly efficiency, eliminating the need for repeated manual confirmation of the slot orientation. Verification shows that assembly time is reduced by more than 60% compared to traditional methods, greatly improving production line efficiency. Simultaneously, it reduces the error rate by physically restricting the insertion of screws (screws in the wrong orientation cannot be inserted), eliminating the problem of incorrect placement of the connection end at the source, reducing the orientation error rate to near zero, and ensuring product consistency. Furthermore, its simple structure and ease of operation make it suitable for widespread application. Attached Figure Description

Detailed Implementation

[0012] The screw fixing auxiliary device of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0013] This embodiment discloses a screw fixing auxiliary device, such as... Figure 1 As shown, it includes a base 1 and a positioning block 2; the positioning block 2 is disposed on the positioning block 2; a limiting boss 5 is provided on the top of the positioning block 2. By providing the limiting boss 5, the groove at the end of the screw to be positioned 7 is engaged when the screw is fixed, and the screw is positioned so that the position and direction of the groove at the end of the screw meets the requirements.

[0014] like Figure 3As shown in this embodiment, the limiting boss 5 is in the shape of a flathead screw; the screw to be positioned 7 is a flathead screw. A sliding groove 3 is provided on the base 1; the aforementioned positioning block 2 is disposed in the aforementioned sliding groove 3. Two positioning blocks 2 are disposed in the sliding groove 3. By placing the positioning block 2 in the sliding groove 3, the stability of the positioning block 2 can be improved, and the positioning effect can be improved; at the same time, the upper end of the base 1 can be provided with a relatively flat operating surface, which facilitates the placement of the screw to be positioned 7 and improves the operating efficiency.

[0015] In the embodiments disclosed herein, such as Figure 2 As shown, a through hole 4 is provided at the bottom of the sliding groove 3; a fixed threaded hole is provided at the bottom of the positioning block 2; the positioning block 2 is connected to the base 1 by a fastening screw 6 through the through hole 4 and the fixed threaded hole at the bottom of the positioning block 2. Fixing the positioning block 2 to the base 1 improves stability and thus improves the positioning effect of the positioning screw 7.

[0016] When using it, the following stages are included: Pre-positioning stage: Secure the two positioning blocks 2 to the base 1 using fastening screws 6, ensuring that the distance between the two positioning blocks 2 precisely matches the distance between the slotted screws to be positioned. This ensures that the limiting boss 5 is precisely aligned with the slotted screw, providing a solid foundation for subsequent assembly.

[0017] Installation phase: Align the slot of the aircraft insert flathead screw with the limiting boss 5 and insert it. Use the fixing auxiliary device and the structural constraints of the screw and aircraft insert to force the aircraft insert flathead screw to complete the assembly in a uniform direction, while avoiding directional deviations caused by manual operation.

[0018] Locking stage: Using an electric screwdriver, tighten the nut that matches the flathead screw with the aviation insert according to the preset torque. By utilizing the locking action of the limiting boss 5 and the slot of the flathead screw, "direction locking + torque locking" are achieved simultaneously to complete the assembly.

[0019] In another embodiment of this utility model, such as Figure 4 As shown, the hexagonal groove is used to fit the hexagonal end of the screw 7 to be positioned, and its usage process is the same as that of the aforementioned slotted screw.

[0020] It should be noted that in specific applications, operators can set corresponding limiting bosses 5 or grooves on the positioning block 2 according to the shape of the screw end that needs to be positioned, and the positioning of the screw 7 to be positioned can be achieved by following the implementation steps described in this embodiment.
