Description

Technical Field

[0001] The utility model belongs to the field of helicopter process equipment design, and particularly relates to an auxiliary device for assembling a helicopter control box. Background Technique

[0002] The control box of a helicopter has a complex structure and many assembly parts. Generally, after the outer shell structure of the control box is riveted into shape, the internal parts are installed. When installing the internal parts, the placement posture of the outer shell of the control box directly affects the installation efficiency of its internal parts. The original auxiliary bracket for installing the control box is relatively simple and only plays a supporting role. It has neither fixation nor flipping function, which is not conducive to the installation of the internal parts of the control box. Content of the Utility Model

[0003] Purpose of the utility model: To propose an auxiliary device for assembling a helicopter control box, which is used to replace the original auxiliary bracket for installing the control box, facilitate the installation of the internal parts of the control box, and improve the installation efficiency.

[0004] Technical Solution

[0005] The utility model provides an auxiliary device for assembling a helicopter control box, including: a positioning frame, a support frame, a first bearing with a journal, and a second bearing with a tangential pressing member;

[0006] The positioning frame is used to position, support and fix the outer shell of the control box. The two ends of the positioning frame are respectively installed on the support frame through the first bearing and the second bearing. Six connecting seats are provided, and these connecting seats correspond to six installation holes on the control box housing for connecting the control box housing;

[0007] Both the first bearing and the second bearing have two states: locking and unlocking. The first bearing can be locked at a certain angle.

[0008] Furthermore, the connecting seat adopts a single-ear with-hole structure to simulate the connection method between the control box housing and the airframe.

[0009] Furthermore, the first bearing is a navigation standard part HB982, which rotates and is fixed at 90°, and is used in combination with the bearing with a tangential pressing member.

[0010] Furthermore, the second bearing is a navigation standard part HB527, which can rotate at any angle, be pressed and fixed, and is used in combination with the bearing with a journal.

[0011] Furthermore, four movable casters with wheel brakes are arranged at the bottom of the support frame to facilitate the movement of this device.

[0012] Furthermore, the connecting seat and the control box housing can be connected by bolts or quick-release pins.

[0013] Beneficial Effects:

[0014] Provide an auxiliary device for the assembly of a helicopter control box, which has a simple structure and is convenient to operate. It can effectively position, support and fix the control box housing. The device can rotate at a 90° angle, thus facilitating the installation of internal components of the control box and improving the installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In view of the structural characteristics of the control box, the present utility model designs an auxiliary device for the assembly of a helicopter control box. The device can fix the control box and drive the control box to flip within a certain angular range, thus facilitating the installation of internal components of the control box and improving the installation efficiency.

[0022] The present utility model provides an auxiliary device for the assembly of a helicopter control box, as Figure 1 shown. The main structural components of the device include a positioning frame, a support frame, a bearing with a journal, and a bearing with a tangential pressing member.

[0023] The positioning frame is as Figure 2 shown and is used to position, support and fix the control box housing. Six connecting seats are arranged thereon, and the connecting seats correspond to six mounting holes of the control box housing for connecting the control box housing.

[0024] The connecting seats on the positioning frame adopt a single-ear with-hole structure to simulate the connection mode between the control box housing and the airframe. The connecting seats and the control box housing can be connected by bolts or quick-release pins.

[0025] The support frame is as Figure 3 shown and is used to support the positioning frame. The two are connected by a bearing with a journal and a bearing with a tangential pressing member.

[0026] Four movable casters with wheel brakes are provided at the bottom of the support frame, facilitating the movement of the device.

[0027] The bearing with a journal is as Figure 4 shown, which is a navigation mark part HB982. This bearing rotates and fixes at 90°, and is used in combination with a bearing with a tangential pressing part.

[0028] The bearing with a tangential pressing part is as Figure 5 shown, which is a navigation mark part HB527. It can rotate at any angle, press and fix, and is used in combination with a bearing with a journal.

[0029] An example of the use of this utility model is as Figure 6 shown. When in use, align the six mounting holes on the control box housing with the six connecting seats on the positioning frame of the device, and use bolts or quick-release pins to connect and fix them, then the support and fixation operations of the control box housing part can be completed. According to the installation angle requirements of the internal components of the control box, rotate the positioning frame to the preset angle and fix it, and then perform the installation operation of the internal components of the control box. After the installation of the internal components of the control box is completed, remove the control box, and use the movable casters at the bottom of the device to move the device to the placement area.
