Description

Technical Field

[0001] This utility model belongs to the field of aviation repair technology and relates to an auxiliary device for assembling suspension beam springs, specifically relating to the assembly of springs inside aircraft suspension beams. Background Technology

[0002] During a major overhaul of a certain type of aircraft, the repair scope and depth of its suspension beams exceeded those of previous aircraft suspension beam repairs. While repairs on other aircraft did not require disassembling the internal springs, repairs on this particular aircraft required the removal of these springs to meet the technical requirements of the overhaul. Upon completion of the repair and reassembly, the confined space inside the suspension beam and the large wire diameter and high force of the springs made spring assembly difficult, necessitating the use of clamps. Utility Model Content

[0003] This utility model provides an auxiliary device for assembling hanging beam springs, which solves the problems of limited internal space of the hanging beam, large spring wire diameter, large force, and difficulty in spring assembly, thereby realizing the compression of the spring inside the hanging beam and the assembly of the pins at both ends of the spring core rod.

[0004] The present invention adopts the following technical solution:

[0005] A beam spring assembly auxiliary device, comprising a left grooved component, a right grooved component, and a screw 6.

[0006] The left slotted component includes a threaded hole plate 1, a long base plate 3, an arc-shaped blocking plate 4, and a long fixing plate 5. The long base plate 3 is fixed to the lower surface of the threaded hole plate 1, and the two are arranged at right angles. The lower part of the threaded hole plate 1 is provided with a threaded through hole. There are two long fixing plates 5, which are fixed to both sides of the upper surface of the long base plate 3 along the length direction to form a slot. The inner diameter of the slot is set according to the outer diameter of the hanging beam spring, and it is used to place the hanging beam spring. The arc-shaped blocking plate 4 is installed at the end of the long base plate 3 away from the threaded hole plate 1. It has an arc-shaped avoidance groove to avoid the hanging beam spring core rod and to hang the end of the hanging beam spring.

[0007] The right slotted component includes a short fixing plate 7, a short bottom plate 8, a one-way thrust ball bearing 10, a perforated plate 11, another reinforcing plate 2, and another arc-shaped blocking plate 4. The right slotted component is basically the same as the left slotted component in structure, except that the short fixing plate 7 and the short bottom plate 8 are shorter than the long bottom plate 3 and the long fixing plate 5, so that the entire hanging beam spring assembly auxiliary device can be inserted into the hanging beam. In addition, the lower part of the perforated plate 11 is a through hole, in which a one-way thrust ball bearing 10 is installed. The two ends of the hanging beam spring are placed in the slots of the two slotted components, and the ends are hung on the two arc-shaped blocking plates 4.

[0008] One end of the screw 6 is installed in the one-way thrust ball bearing 10 at the lower part of the perforated plate 11, and the other end is threaded to cooperate with the threaded hole at the lower part of the threaded plate 1. Rotating the screw 6 causes the left and right grooved parts to move relative to each other, thereby compressing the hanging beam spring. The end of the screw 6 installed in the one-way thrust ball bearing 10 has a through hole through which the lever 9 passes to rotate the screw 6.

[0009] Furthermore, reinforcing plates 2 are fixed between the threaded hole plate 1 and the long base plate 3, and between the short base plate 8 and the smooth hole plate 11, to increase strength and rigidity.

[0010] Furthermore, the left and right slotted parts are either welded or integral structures.

[0011] The beneficial effects of this utility model are: This utility model solves the problems of limited internal space of the hanging beam, large wire diameter of the hanging beam spring, large force, and difficulty in assembling the hanging beam spring, thereby realizing the compression of the hanging beam spring inside the hanging beam and the assembly of the pins at both ends of the hanging beam spring core rod, filling the gap of this type of tool device.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below.

[0018] A beam spring assembly auxiliary device, comprising a left grooved component, a right grooved component, and a screw 6, as shown below. Figure 1 As shown.

[0019] The left slotted component is an integral structure, including a threaded hole plate 1, a reinforcing plate 2, a long base plate 3, an arc-shaped blocking plate 4, and a long fixing plate 5. The long base plate 3 is fixed to the lower surface of the threaded hole plate 1, and the two are arranged at a right angle. A reinforcing plate 2 is fixed between them to enhance strength and rigidity. The lower part of the threaded hole plate 1 is provided with a threaded through hole, such as... Figure 2 As shown; two long fixing plates 5 are provided, fixed to both sides of the upper surface of the long base plate 3 along its length, forming a groove. The inner diameter of the groove is set according to the outer diameter of the hanging beam spring, and is used to place the hanging beam spring, such as... Figure 3 As shown; the arc-shaped blocking plate 4 is installed at the end of the long base plate 3 away from the threaded hole plate 1, and it has an arc-shaped avoidance groove to avoid the hanging beam spring core rod and to hang the end of the hanging beam spring.

[0020] The right slotted component is also an integral structure, including a short fixing plate 7, a short bottom plate 8, a one-way thrust ball bearing 10, a perforated plate 11, and another arc-shaped blocking plate 4. The right slotted component is basically the same as the left slotted component in structure, except that the short fixing plate 7 and the short bottom plate 8 are shorter than the long bottom plate 3 and the long fixing plate 5, so that the entire hanging beam spring assembly auxiliary device can be inserted into the hanging beam. In addition, the lower part of the perforated plate 11 is a through hole, and a one-way thrust ball bearing 10 is installed in the hole to avoid friction when the screw 6 rotates. The two ends of the hanging beam spring are placed in the slots of the two slotted components, and the ends are hung on the two arc-shaped blocking plates 4.

[0021] like Figure 4 As shown, one end of the screw 6 is installed in the one-way thrust ball bearing 10 at the lower part of the perforated plate 11, and the other end is threaded to cooperate with the threaded hole at the lower part of the threaded plate 1. Rotating the screw 6 causes the left and right grooved parts to move relative to each other, thereby compressing the hanging beam spring. The end of the screw 6 installed in the one-way thrust ball bearing 10 has a through hole for the lever 9 to pass through and rotate the screw 6. Since the hanging beam spring wire diameter is relatively thick and needs to be compressed to more than 100mm, the force is very large. Therefore, the lever 9 can move to both sides and needs to be long enough to save effort when rotating the screw 6.

[0022] In use, place both ends of the hanging beam spring in the slots of the left and right grooved parts, and hang the ends on the two arc-shaped blocking plates 4. Insert the hanging beam spring and the hanging beam spring assembly auxiliary device into the hanging beam through the opening of the hanging beam. Use the lever 9 to rotate the screw 6 to move the left and right grooved parts relative to each other, compress the hanging beam spring to the required length, and complete the installation of the hanging beam spring.
