Description

Technical Field

[0001] This utility model relates to the fields of aviation manufacturing and maintenance technology, and specifically to an auxiliary working clamp for cable disassembly. Background Technology

[0002] During aircraft maintenance, cables often need to be moved and inserted through the aircraft's access hatch. However, due to the small size of the hatch, only a portion of the operator's fingers can fit through, and the cables are tightly packed together, making slippage difficult. Manual operation is time-consuming, labor-intensive, and inefficient. Using general-purpose tools is problematic because the tool's gripping end shape and size do not match the cable's dimensions, leading to cable slippage or damage to the cable's insulation during movement. Therefore, specialized pliers for assisting in cable disassembly are needed. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an auxiliary working clamp for cable disassembly. While ensuring the structural strength of the tool, the overall structural design of the tool reduces its size to accommodate the size of the jaw frame. At the same time, it ensures that the shape of the jaws matches the size of the cable, facilitating the clamping and dragging of the cable, and making it convenient for operators to use.

[0004] The technical solution of this utility model:

[0005] A cable disassembly auxiliary clamp includes an arc-shaped clamping port A, an arc-shaped clamping port B, a rotating shaft, a handle A, and a handle B. The arc-shaped clamping port A is located at the front end of handle A, and the two are integrally formed. The arc-shaped clamping port B is located at the front end of handle B, and the two are integrally formed. Both handles A and B have semi-circular notches in their middle sections, with two opposing semi-circular notches for mounting the rotating shaft. The rotating shaft connects the two integral structures into a cross-shaped combination. When the clamp is closed, the arc-shaped clamping ports A and B close to form a complete circular structure, located on one side of the front end of handles A and B.

[0006] The radial dimension of the rotating shaft is 15mm, the axial length is 10mm, and the distance from the center point of the rotating shaft to the arc-shaped clamping port A and the arc-shaped clamping port B is 80mm.

[0007] The inner diameter of the arc-shaped clamping port A and arc-shaped clamping port B when closed is 20mm, the thickness of arc-shaped clamping port A and arc-shaped clamping port B is 3mm, and the height is 5mm; the distance from the center point of the rotating shaft to the end of arc-shaped clamping port A and arc-shaped clamping port B is 200mm, and the bending angle of arc-shaped clamping port A and arc-shaped clamping port B is 135°.

[0008] The beneficial effects of this utility model are:

[0009] (1) This utility model adopts an integrated structural design, which is convenient to use. The size of the arc-shaped clamping port can be adapted to most of the frames on the aircraft, and the range of motion is relatively flexible.

[0010] (2) After clamping the cable, the arc-shaped clamping port of this utility model can fit tightly with the cable to be disassembled, reducing the possibility of tool slippage and cable damage caused by improper clamping angle, thereby improving work efficiency and product quality.

[0017] The specific embodiments of this utility model are further described below with reference to the accompanying drawings and technical solutions.

[0018] This embodiment provides an auxiliary working clamp for cable disassembly, such as... Figure 1As shown, the clamp includes an arc-shaped clamping port A1, an arc-shaped clamping port B2, a rotating shaft 3, a handle A4, and a handle B5. Arc-shaped clamping port A1 is located at the front end of handle A4, and arc-shaped clamping port B2 is located at the front end of handle B5; both are integral structures. Handles A4 and B5 have semi-circular notches in the middle, with the two semi-circular notches facing each other, for mounting the rotating shaft. The rotating shaft connects the two integral structures into a cross-shaped combination. When the clamp is closed, arc-shaped clamping ports A1 and B2 close to form a complete circular structure, located on one side of the front end of handles A4 and B5.

[0019] Based on the actual use of the tool, in order to maintain the stability of the arc-shaped clamping ports A1 and B4 when closed, the radial dimension d of the rotating shaft 3 is designed to be 15mm, the axial length e is designed to be 10mm, and the distance f from the center point of the rotating shaft 3 to the arc-shaped clamping ports A1 and B2 is designed to be 80mm. Figure 4 and Figure 5 As shown, the inner circle diameter g formed by the arc-shaped clamping port A and arc-shaped clamping port B when closed is designed to be 20mm, the thickness h of the arc-shaped clamping port A1 and arc-shaped clamping port B2 is designed to be 3mm, and the height i is designed to be 5mm; Figure 2 As shown, the distance j from the center point of the rotating shaft to the ends of the arc-shaped clamping ports A1 and B4 is designed to be 200mm; Figure 3 As shown, the bending angle α of the arc-shaped clamping port A1 and the arc-shaped clamping port B2 is designed to be 135°.

[0020] When using the device, the operator can control the opening and closing of the arc-shaped clamping ports A1 and B2 by controlling the opening and closing of handles A4 and B5. When the arc-shaped clamping ports A1 and B2 are inserted into the jaws, the cable can be clamped in the circular jaws formed by the arc-shaped clamping ports A1 and B2. Then, using the edge of the jaws as a support point, the arc-shaped clamping ports A1 and B2 are dragged against the edge of the jaws. Since the bending angle of the arc-shaped clamping ports A1 and B2 relative to handles A4 and B5 is 135°, compared with other angles, it can better adapt to the size of most jaws. While ensuring that the strength meets the requirements, it is also more convenient for the arc-shaped clamping ports A1 and B2 to move inside the jaws.
