Description

Technical Field

[0001] The utility model belongs to the technical field of aviation assembly and relates to a flap position mechanism positioning guide hole fixing device. Background Art

[0002] As a main control system of an aircraft, the flap control system of a certain type of aircraft is composed of electrical, hydraulic, mechanical systems and other subsystems, and plays a vital role in the take-off and landing of the aircraft. The quality of the state adjustment of the flap retraction and extension system directly affects the take-off and landing quality of the aircraft. The general assembly stage mainly undertakes the adjustment, debugging, cross-linking test and other related work of the aircraft flap retraction and extension system. The hole making of the flap position mechanism needs to be carried out after the adjustment of the main flap system is completed. First, use the flap handle to retract the flap to zero position, then rotate the flap position mechanism to zero position, and lead the hole from the initial hole on the flap position mechanism worm to the flap transmission rod, and fix it with bolts. Due to the influence of spatial position, some positions cannot be constructed, and can only be positioned by marking and re-adjusting the position for hole making. At present, there is no suitable tool or equipment to fix the flap position mechanism on the flap transmission rod. The flap position mechanism can only be fixed manually. Since the flap position mechanism worm and flap transmission rod are hollow rods, the hole making process is prone to movement, resulting in hole making position deviation. It affects the zero position state of the flap backup system, causing the adjustment workload and difficulty to increase and the work efficiency to decrease. Utility Model Content

[0020] The utility model is further described below in conjunction with the embodiments. The following are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the above technical problems, this utility model patent is realized through the following technical solutions:

[0022] Since the flap position mechanism worm and transmission rod are both hollow tubular bodies, the fixing device is configured as two semicircular blocks for easy disassembly and assembly. Figure 1 As shown, a flap position mechanism positioning guide hole fixing device is provided, including a semicircular clamping block A1, a semicircular clamping block B2, a connecting cylindrical pin 3, a connecting screw 4, a nut 5, and a positioning screw 6.

[0023] The semicircular clamping block 1 of the fixing device is provided with an opening slot 11 for observing the installation of the positioning screw, and the tapped screw hole 12 is used for positioning the positioning screw 6. The semicircular clamping block 1 is connected to the semicircular clamping block 2 by connecting the cylindrical pin 3.

[0024] The semicircular block 2 is provided with a U-shaped opening groove 21 for guiding the worm to the transmission rod after the flap position mechanism is positioned.

[0025] When positioning the worm of the flap position mechanism, adjust the position of the fixing device to allow the positioning screw 6 to pass through one of the bottom holes on the worm of the flap position mechanism, and fix the device to the worm of the flap position mechanism and the transmission rod by locking the semicircular clamp 1 and the connecting screws 4 and the nuts 5 on the semicircular clamp 2. Due to limited space, when the U-shaped opening groove on the semicircular clamp 2 is inconvenient to make a hole after the device is fixed, the flap transmission rod position can be adjusted by placing the flap to reach the position of the U-shaped opening groove on the fixing device to meet the requirements of the on-board hole.

[0026] The utility model elevator lock mechanism positioning auxiliary device is described in detail with reference to the accompanying drawings:

[0027] Example 1: The outer diameter of the flap position mechanism worm is 38mm, the outer diameter of the flap transmission rod is 35mm, and the upper bottom hole of the worm is Φ4mm;

[0028] To ensure that the flap position mechanism positioning hole fixing device is fixed to the worm and transmission, the inner diameter of one section of the semicircular block of the fixing device that fits the worm is 40mm, and the inner diameter of the other section that fits the transmission rod is 37mm. A layer of 1mm thick rubber pad is attached to the inside, and the diameter of the positioning screw embedded in the bottom hole of the worm is 3.9mm.

[0029] Example 2: The outer diameter of the flap position mechanism worm is 40mm, the outer diameter of the flap transmission rod is 37mm, and the upper bottom hole of the worm is Φ5mm;

[0030] To ensure that the flap position mechanism positioning hole fixing device is fixed to the worm and transmission, the inner diameter of one section of the semicircular block of the fixing device that fits the worm is 42mm, and the inner diameter of the other section that fits the transmission rod is 39mm. A layer of 1mm thick rubber pad is attached to the inside, and the diameter of the positioning screw embedded in the bottom hole of the worm is 4.9mm.

[0031] The specific steps are as follows:

[0032] Step 1: Adjust the main flap system first, and use the handle to retract the flaps to zero position;

[0033] Step 2: Rotate the worm of the flap position mechanism to zero position and check that the position mechanism is in the power-off position;

[0034] Step 3: Insert the positioning screw 6 on the positioning hole fixing device of the flap position mechanism into the bottom hole of the worm of the flap position mechanism as required;

[0035] Step 4: Connect the semicircular blocks 1 and 2 of the fixture with connecting screws and nuts, and check whether the U-shaped opening position on the semicircular block 2 is suitable for the hole. If the position is not suitable, use the handle to put the flap to a certain angle until the appropriate hole making angle is found. After the position is determined, the hole is made from the flap position mechanism worm to the transmission rod;

[0036] Step 5: After the single-side hole is completed, adjust the flap position mechanism to locate the hole fixing device, and drill the hole on the other side in the same way. After disassembling the disassembly device, use bolts to connect and fix the flap position mechanism and the transmission rod.
