[0027] like Figures 1 to 3 As shown, this utility model discloses a compression fixture for a high-pressure air duct spring.

[0028] like Figure 1 and Figure 2 As shown, the compression fixture for the high-pressure bleed valve spring includes a base plate 1, a fixing assembly, a first support plate 2, and a lead screw 5. The fixing assembly is disposed on the upper surface of the base plate 1 and is used to fix the high-pressure bleed valve 11; the first support plate 2 is connected to the base plate 1; the lead screw 5 is rotatably disposed on the first support plate 2 and one end of the lead screw 5 passes through the first support plate 2, and one end of the lead screw 5 is used to abut against the cover plate 13 of the high-pressure bleed valve 11.

[0029] like Figure 3As shown, in this embodiment, when disassembling the spring 12 of the high-pressure bleed valve 11, first place the high-pressure bleed valve 11 on the upper surface of the base plate 1, then use the fixing assembly to firmly fix the high-pressure bleed valve 11, adjust the screw 5 until one end of the screw 5 abuts against the cover plate 13 of the high-pressure bleed valve 11, then remove the mounting screw of the cover plate 13, and then slowly rotate the screw 5 to release the force of the spring 12. After the force of the spring 12 is completely released, the cover plate 13 and the spring 12 can be removed. When assembling the spring 12 of the high-pressure bleed valve 11, first place the high-pressure bleed valve 11 on the upper surface of the base plate 1, then use the fixing assembly to firmly fix the high-pressure bleed valve 11, install the cover plate 13 onto the spring 12, adjust the screw 5 until one end of the screw 5 abuts against the cover plate 13 of the high-pressure bleed valve 11, slowly rotate the screw 5 to compress the spring 12, and when compressed to the preset length, install the mounting screw of the cover plate 13.

[0030] In some embodiments of this example, the fixing assembly includes two clamping structures 7 disposed on the upper surface of the base plate 1. A receiving space for placing the high-pressure bleed valve 11 is formed between the two clamping structures 7 and the lead screw 5.

[0031] In some embodiments of this example, at least one clamping structure 7 is provided with a pad 9 between itself and the upper surface of the base plate 1. For example, one clamping structure 7 is provided with a pad 9 between itself and the upper surface of the base plate 1, and another clamping structure 7 is directly disposed on the upper surface of the base plate 1; or, both clamping structures 7 are provided with pads 9 between themselves and the upper surface of the base plate 1.

[0032] In some embodiments of this example, the pad 9 is a height-adjustable support block, that is, the height of the corresponding clamping structure 7 can be adjusted by adjusting the height of the pad 9 in order to fix the high-pressure bleed valve 11.

[0033] In some embodiments of this example, the compression fixture further includes a second support plate 8. The first support plate 2 and the second support plate 8 are respectively connected to two opposite sides of the base plate 1. The first support plate 2, the second support plate 8 and the base plate 1 form an H-shaped structure. The bottom of the first support plate 2 and the second support plate 8 form a support portion, which reduces the requirements for the work site.

[0034] In some embodiments of this example, the upper surface of the compression fixture is provided with a positioning pin 10, which is used to fix the high-pressure bleed valve 11, thereby improving the stability of the high-pressure bleed valve 11. For example, when fixing the high-pressure bleed valve 11, the high-pressure bleed valve 11 is first positioned using the positioning pin 10, and then the high-pressure bleed valve 11 is fixed using the fixing assembly.

[0035] In some embodiments of this example, the end of the lead screw 5 that abuts against the cover plate 13 is provided with a top block 6. The top block 6 abuts against the cover plate 13 of the high-pressure bleed valve 11. The end of the lead screw 5 with the top block 6 faces the receiving space formed by the first support plate 2, the second support plate 8, and the lead screw 5. In these embodiments, by providing a top block 6 at one end of the lead screw 5, it is convenient to abut against the cover plate 13 of the high-pressure bleed valve 11, avoiding wear and other damage caused by direct contact between the cover plate 13 and the lead screw 5.

[0036] In some embodiments of this example, a handwheel 3 is provided at the end of the lead screw 5 away from the cover plate 13. In these embodiments, the lead screw 5 can be adjusted by rotating the handwheel 3, which improves the convenience of operation.

[0037] For example, the lead screw 5 has a first end and a second end. The first end of the lead screw 5 is provided with a pad 9, which is used to abut against the cover plate 13. The second end of the lead screw 5 is provided with a handwheel 3, which can be rotated to realize the rotation of the lead screw 5.

[0038] In some embodiments of this example, the first support plate 2 has a horizontal through hole penetrating the first support plate 2, and a nut 4 is fixedly installed in the through hole. The lead screw 5 is rotatably mounted on the first support plate 2 through cooperation with the nut 4. In these embodiments, through the cooperation between the nut 4 and the lead screw 5, the lead screw 5 can be moved horizontally by rotation, and the position of the lead screw 5 is kept stable when it is not necessary to adjust the lead screw 5.

[0039] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
