Description

Technical Field

[0001] The present invention relates to the field of installation, and in particular to the field of pipeline clamp installation tooling. Background Art

[0002] The current aircraft engine pipeline and cable fixing structure usually adopts P-type pipeline fixing clamps to fix the pipelines and cables to the mounting base or bracket. The pipeline P-type clamp is a single-ear clamp used to fix pipelines and cables. It is usually made of metal and has a wear-resistant material liner such as rubber, resin or metal felt at the fixing position of the pipeline and cable. The P-type clamp structure includes a clamping end for tightening the pipeline or cable and a fixed end for fixing the clamp to the mounting base or directly on it. The fixed end usually includes two upper and lower clamping plates. During assembly, the pipeline or cable passes through the middle of the clamping end and is fixed to the clamping end. The upper and lower clamping plates of the fixed end are provided with through holes to allow bolts and other connecting parts to pass through, and the clamp is fixed to an external fixed base such as a mounting frame or bracket.

[0003] During the bolt tightening process, the upper and lower metal sheets at the fixed end are subjected to the installation torque transmitted by the bolt during the tightening torque, causing relative twisting, which can cause the entire clamp to twist. This process can make the clamp unusable or reduce the service life of the clamp. Summary of the Invention

[0004] One object of the present invention is to provide a pipeline clamp anti-twist fastening auxiliary tooling for positionally constraining the clamp, pipeline, and wrench, thereby avoiding relative twisting during the application of installation torque, which may cause torsional damage to the clamp.

[0005] To achieve the above-mentioned purpose, the pipeline clamp anti-twist fastening auxiliary tooling is used to limit the position of the clamp, pipeline, and wrench. The clamp includes a fixed end and a clamping end. The clamping end is used to clamp the pipeline. The fixed end includes a pair of compression plates, which are used to connect with an external fixing seat through a fastener to fix the pipeline on the external fixing seat. The auxiliary tooling includes a main body, a bayonet, a claw, and a limiting groove. The main body includes a horizontal part and a vertical part; the bayonet is provided on the vertical part for fixing the wrench; the claw is provided on the horizontal part for simultaneously holding the pipeline and the clamping end; the limiting groove is provided on the horizontal part for clamping the compression plate to prevent the compression plate from twisting under the installation torque from the wrench, and works together with the claw to prevent the clamp itself from twisting and the pipeline from deflecting.

[0006] In one or more embodiments, the limiting groove includes a first limiting groove and a second limiting groove, the first limiting groove is used to clamp the outer peripheral surface of the pressing plate, and the second limiting groove is used to accommodate the clamping end.

[0007] In one or more embodiments, the claw is provided at one end of the second limiting groove and is integrally provided with the horizontal portion.

[0008] In one or more embodiments, the auxiliary tooling includes a plurality of jaws with different inner diameters, and each of the jaws is replaceably connected to the horizontal portion.

[0009] In one or more embodiments, the auxiliary tooling includes a plurality of claws for clamping the pipeline and the clamping end at different positions respectively.

[0010] In one or more embodiments, the bayonet is detachably connected to the vertical portion.

[0011] In one or more embodiments, the horizontal portion and the vertical portion are detachably connected.

[0012] In one or more embodiments, the auxiliary tooling is a one-piece piece.

[0013] The above pipeline clamp anti-twist fastening auxiliary tooling limits and clamps the clamping plate through the limit groove, avoiding the relative twisting of the clamping plate following the torque, and further avoiding the twisting of the clamp itself and the deflection of the pipeline through the clamping action of the claws. The above limit clamping can effectively ensure the stability of the clamp during installation, avoid relative twisting during the application of installation torque, and improve the service life of the clamp.

[0037] The present invention is further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description herein. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0038] It should be noted that these and other subsequent drawings are only examples and are not drawn to scale, and should not be used to limit the actual scope of protection required by the present invention.

[0039] The clamp includes a fixing end 11 and a clamping end 12. Figure 1 and Figure 2 As shown, the clamping end 12 clamps the pipeline 20 and is fixed to the external fixing seat 50 through the fixing end 11. The external fixing seat 50 can be a mounting frame or a bracket, thereby fixing the aircraft engine pipeline and cable to a set position.

[0040] A common fixed end 11 includes two upper and lower compression plates 112. The compression plates 112 are provided with through holes for fasteners 40, such as bolts, to pass through and secure the fixed end 11 to the mounting base or bracket. The fasteners 40 are often tightened by a wrench 30. However, during the tightening torque application process of the wrench 30, the fasteners 40 are subjected to the installation torque transmission effect, and the torsional torque of the fasteners 40 is transmitted to the compression plates 112 of the clamp fixed end 11 through friction, causing the upper and lower compression plates 112 of the fixed end to twist relative to each other, thereby causing the entire clamp 10 to twist, which in turn causes the pipeline 20 to deflect. This process may render the clamp 10 unusable or reduce the service life of the clamp.

[0041] The pipeline clamp anti-twist fastening auxiliary tooling disclosed in the present invention is used to solve the above problems. Figures 3 to 5 As shown, the pipeline clamp anti-twist fastening auxiliary tooling is used to limit the position of the clamp 10, pipeline 20, and wrench 30. The clamp 10 includes a fixed end 11 and a clamping end 12. The clamping end 12 is used to clamp the pipeline 20. The fixed end 11 includes a pair of compression pieces 112, which are used to connect to the external fixing base 50 via a fastener 40 to secure the pipeline 20 to the external fixing base 50.

[0042] The auxiliary tooling includes a main body 1, a clamping jaw 2, a clamping claw 3, and a limiting groove 4. The main body 1 includes a horizontal portion 101 and a vertical portion 102; the clamping jaw 2 is disposed on the vertical portion 102 and is used to secure the wrench 30. In addition, the clamping jaw 2 can also serve as an auxiliary structure for the torque wrench. The clamping jaw 3 is disposed on the horizontal portion 101 and is used to simultaneously clamp the pipeline 20 and the clamping end 12. The limiting groove 4 is disposed on the horizontal portion 101 and is used to clamp the clamping plate 112 to prevent the clamping plate 112 from twisting under the installation torque from the wrench 30. The limiting groove 4 works together with the clamping jaw 3 to prevent the clamp 10 from twisting and the pipeline 20 from deflecting.

[0043] The auxiliary tooling limits the torque wrench 30 through the bayonet 2, simultaneously clamps the pipeline 20 and the clamping end 12 through the claw 3, and clamps the clamping piece 112 of the fixed end 11 through the limiting groove 4. During the application of the installation torque of the fastener 40, the torque wrench 30, the clamp 10, and the pipeline 20 can be limited separately to avoid distortion of the clamp 10 and deflection of the pipeline 20, and effectively prevent torsional deformation of the upper and lower clamping pieces 112.

[0044] In some embodiments, as Figure 5As shown, the limiting groove 4 includes a first limiting groove 41 and a second limiting groove 42. The first limiting groove 41 is used to clamp the outer peripheral surface of the compression plate 112, and the second limiting groove 42 is used to accommodate the clamping end 12. The first limiting groove 41 forms a U-shaped opening, and the size of the opening is set to a length that can clamp the compression plate 112. The width of the second limiting groove 42 is larger than that of the first limiting groove 41, and is used to accommodate the clamping end 12 of the clamp 10 on the pipeline 20. Furthermore, the claw 3 is arranged at one end of the second limiting groove 42, extending from the tail end of the horizontal part 101, and is integrally arranged with the horizontal part 101, while holding the clamping end 12 and a part of the pipeline 20. Through the joint action of the claw 3 and the limiting groove 4, it can be ensured that the fixed end 11 and the clamping end 12 of the clamp do not twist relative to each other under the action of the installation torque, thereby avoiding the distortion of the clamp itself and the deflection of the pipeline.

[0045] In order to provide multiple fastening points, in some embodiments, the auxiliary tooling includes multiple claws 3 for respectively clamping the pipeline 20 and the clamping end 12 at different positions, such as Figure 5 As shown, they are fixed at both ends of the clamp 10 to achieve multiple position limits on the clamp 10 and the pipeline 20.

[0046] For pipelines 20, clamps 10, fasteners 40, and wrenches 30 of different specifications and sizes, the above three limiting structures are standardized and can be made into replaceable structures. For example, in some embodiments, the auxiliary tooling includes a plurality of claws 3 with different inner diameters, each claw 3 is replaceably connected to the horizontal portion 101, and the diameters of pipelines 20 of different sizes are adapted by replacing the claws 3. For another example, in some embodiments, the bayonet 2 is detachably connected to the vertical portion 102 to adapt the size of the wrench 30. Pipelines 20, clamps 10, fasteners 40, and wrenches 30 are mostly standard parts. Therefore, under the premise that the sizes of the standard parts are known, the tooling includes multiple sets of replacement parts to adapt to pipelines 20, clamps 10, fasteners 40, and wrenches 30 of different specifications and sizes.

[0047] In some further embodiments, the auxiliary tooling can also be a single piece, with each piece of auxiliary tooling being configured with different bayonet sizes and retaining groove sizes to facilitate direct replacement. In some embodiments, the horizontal portion 101 and the vertical portion 102 can also be configured to be detachably connected to improve the convenience of tooling installation.

[0048] The above-mentioned pipeline clamp anti-twist fastening auxiliary tooling limits and clamps the clamping plate through the limit groove, thereby preventing the clamping plate from being relatively twisted following the torque, and further prevents the clamp itself from being twisted and the pipeline from being deflected through the clamping action of the claws. By constraining the positions of the clamp, pipeline, wrench or fastener, the stability of the clamp during installation is guaranteed and the service life of the clamp is increased.
