DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the utility model.

[0023] Please refer to Figures 1-4 In the embodiments of the utility model, a fairing guide vane pressing device includes base frame 1, three templates 2 are fixedly connected to the top surface of base frame 1, side frames 3 are fixedly connected to the two sides of base frame 1, two limiting rods 4 are arranged on the top of side frame 3, sliding frames 41 are slidably connected to the side surface of limiting rod 4, jacks 5 are arranged on the bottom of sliding frame 41, top blocks 52 fixedly connected with sliding frame 41 bottom surface are drivingly connected to the output end of jack 5, pressing blocks 51 are fixedly connected to the bottom surface of jack 5, bracing mechanisms 7 are arranged on the two sides of base frame 1, and a plurality of round rods 8 are arranged on the top between the two bracing mechanisms 7.

[0024] Specifically, the heated guide vane plate can be placed on the template 2, and then the jack 5 can be activated to extend it, causing the pressing block 51 to press downward against the guide vane plate. As the jack 5 continues to extend, it can lift the limiting rod 4 upward. After the limiting rod 4 contacts the top crossbar of the side frame 3, the side frame 3 can prevent the limiting rod 4 from moving further upward, thus supporting the limiting rod 4 and consequently the jack 5. As the jack 5 continues to extend, the pressing block 51 can compress the guide vane plate, causing it to deform and press against the top of the template 2, thus pressing the guide vane. After one pressing cycle, the jack 5 can be retracted. The compression mechanism moves the limiting rod 4 downward to its original position and disengages the pressing block 51 from the guide vane. At this time, the sliding frame 41 can move along the surface of the limiting rod 4 and move the limiting rod 4 inside the side frame 3, thereby adjusting the position of the jack 5. Then, the jack 5 can be used to press different parts of the guide vane plate. After pressing, the round rod 8 can be raised by the top support mechanism 7. The round rod 8 can lift the guide vane plate and disengage it from the template 2. At this time, the guide vane plate can be transported by rotating the round rod 8, which makes it easy to remove the guide vane plate from the template 2 and move it out of the pressing device. This helps to reduce the burden on the workers and facilitates the rapid processing of the guide vane.

[0025] Example 1

[0026] like Figures 4-6 As shown, in this embodiment, the top support mechanism 7 includes a side frame 78. A bidirectional lead screw 75 is rotatably connected to the inner side of the side frame 78. Two sliding seats 72 are slidably connected to the side of the bidirectional lead screw 75 and slidably connected to the inner side of the side frame 78. A connecting rod 71 is provided at the top of the side frame 78. Two positioning seats 74 are provided at the bottom of the connecting rod 71. A rotating rod 73 is rotatably connected to the inner side of the adjacent positioning seat 74 and rotatably connected to the inner side of the sliding seat 72. A plurality of plug-in seats 77 are rotatably connected to the side of the connecting rod 71 corresponding to the round rod 8. Both ends of the round rod 8 are slidably connected to the inner side of the adjacent plug-in seat 77. A torsion block 79 is fixedly connected to one end of the bidirectional lead screw 75.

[0027] In specific implementation, the two-way screw rod 75 can be rotated through the twisting block 79, and the two sliding seats 72 on the two-way screw rod 75 can move towards each other when the two-way screw rod 75 is rotated. The sliding seat 72 can lift the connecting rod 71 upwards through the rotating rod 73 and the positioning seat 74. The connecting rod 71 can drive the circular rod 8 to move upwards through the plug-in seat 77, so as to lift the guide vane plate upwards through the circular rod 8. The circular rod 8 is lifted by rotating the two-way screw rod 75, which has a labor-saving effect and is beneficial to reduce the burden of the staff. The plug-in seat 77 can rotate relative to the connecting rod 71, so that the circular rod 8 rotates freely relative to the connecting rod 71. In this way, the guide vane plate can be taken out from the inside of the device. The positioning seat 74 can be directly fixed on the bottom of the connecting rod 71 by welding, or two positioning grooves can be formed on the bottom surface of the connecting rod 71, and the positioning seat 74 is slidably inserted into the adjacent positioning groove. In this way, the connecting rod 71 can be directly taken off from the positioning seat 74, which is convenient for disassembling and assembling the connecting rod 71. The circular rod 8 is slidably inserted into the adjacent plug-in seat 77, which is convenient for disassembling and assembling the plug-in seat 77 between the plurality of templates 2.

[0028] As shown in Figure 6 In this embodiment, the two side frames 78 are fixedly connected with the blocking frames 9 on the side surfaces, and the inner side surfaces of the blocking frames 9 are rotatably connected with the side surfaces of the two two-way screw rods 75. The side surfaces of the two-way screw rods 75 are fixedly sleeved with the toothed belt wheels 76 inside the blocking frames 9, and the two toothed belt wheels 76 are driven in meshing transmission through the toothed belt.

[0029] In specific implementation, when one two-way screw rod 75 is rotated through the twisting block 79, the other two-way screw rod 75 can be driven to rotate through the toothed belt wheel 76, so that the two two-way screw rods 75 are synchronously rotated, and the two connecting rods 71 are synchronously lifted upwards or lowered down, which is convenient for lifting or lowering the guide vane plate.
