Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment 1:
[0024] Please refer to Figures 1 to 4 , a special fixture for preventing deformation in the welding of a titanium alloy fairing in this embodiment, including an M-shaped base 1, two studs 7 are internally threaded on the side of the M-shaped base 1, and a stud thread 11 matching the stud 7 is provided inside the M-shaped base 1 near one side of the stud 7. An anti-deformation fixture is arranged in the middle of the M-shaped base 1. The anti-deformation fixture includes two bearings 2 sleeved in the middle inside the M-shaped base 1, an M-shaped base concave hole 13 opened at one end of the M-shaped base 1 near the bearing 2 inside, a fixed nut tube boss cylinder 12 sleeved inside the two bearings 2, a fixed nut tube 3 sleeved on the inner wall of the fixed nut tube boss cylinder 12, a right-handed screw 4 threadedly connected inside one of the fixed nut tubes 3, a left-handed screw 5 threadedly connected inside the other fixed nut tube 3, a right-handed thread 10 opened on the right side inside the M-shaped base 1, and a left-handed thread 9 opened on the left side inside the M-shaped base 1.
[0025] Among them, spacer blocks 6 are sleeved on the end faces of the left-handed screw 5 and the right-handed screw 4 near the stud 7. Fixed nut tube threads 8 are penetrated and opened inside the two fixed nut tubes 3. One end of the right-handed screw 4 and the left-handed screw 5 respectively penetrates inside the two fixed nut tubes 3 and extends to the outside. The external threads of the right-handed screw 4 and the left-handed screw 5 cooperate with the internal threads of the fixed nut tube thread 8. The threads of the left-handed screw 5 and the right-handed screw 4 are opposite. The internal threads of the two fixed nut tubes 3 are opposite to the internal threads of the two stud threads 11. The stud 7 extends from inside the stud thread 11 to the outside. The external thread of the stud 7 cooperates with the internal thread of the stud thread 11.
[0026] It should be noted that the right-handed screw 4 and the left-handed screw 5 must be used in conjunction with the right-handed thread 10 and the left-handed thread 9 inside the M-shaped base 1. Without the cooperation, the right-handed screw 4 and the left-handed screw 5 cannot achieve telescopic movement with the rotation of the fixed nut tube 3.
[0027] Embodiment 2:
[0028] See also Figure 1 , Figure 2 and Figure 4 , based on the first embodiment, includes a middle handle fixedly connected to the upper side of the M-shaped base 1.
[0029] By adopting the above technical solution, the portability of taking is improved.
[0030] The working principle of the above embodiment is:
[0031] The operator first holds the handle of the M-type base 1 with his left hand, and then turns the fixed nut tube 3 to rotate around the axis at the same position. The internal thread of the fixed nut tube 3 drives the right-hand screw 4 to rotate and extend or contract from the right-hand thread 10 of the inner hole of the M-type base 1. When the right-hand screw 4 extends to a certain distance from the workpiece, a cushion block 6 is installed on the top of the right-hand screw 4, and then the fixed nut tube 3 is continued to be turned. After the cushion block 6 is tightly fitted with the workpiece, the rotation stops. Then, the studs 7 are pulled inward at both sides of the M-type base 1, and the cushion block 6 is installed and continues to extend inward until the cushion block 6 is tightly fitted with the surface of the workpiece. Repeat the operation on the other side. At this point, the parallel thin walls at both ends of the workpiece are fixed.
[0032] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects.
