Description

A extracting tool for aircraft round pin axle

Technical Field

The utility model belongs to the technical field of the aircraft maintenance tool and specifically relates to an instrument that is used for aircraft round pin axle to dismantle.

Background

The aircraft pin shaft is an important part with high requirements on safety and reliability on an aircraft, is a bridge connected between organisms, needs to bear high load, has an extremely important effect on the safe connection of the aircraft, and has high requirements on the reliability of the connection of the aircraft, but because the aircraft pin shaft is specially designed in appearance, the assembly is relatively complex, supporting legs are required to be designed for the aircrafts or parts of different models according to conditions, the dismounting tool is poor in universality, and the dismounting and mounting of the pin shaft can be realized by special tools. The round pin axle often needs to be dismantled and the installation in the use, dismantles the in-process, need make instrument and part closely laminate, after looking for the atress strong point, will sell the axle and pull out outside the organism again, and the instrument of this kind of structure generally needs great operating space, just is not convenient for use in the narrow and small place in space. If no customized special tool is provided, the dismounting tool cannot find the supporting point, so that the pin shaft cannot be dismounted, and the secondary moving efficiency of the airplane is influenced.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a extracting tool for aircraft round pin axle sets up ratchet and screw rod on bow-shaped support, utilizes the removal of screw thread rotation control screw rod to extract the round pin axle to set up fixing device and be used for providing the fixed point at the bow frame tip.

A disassembling tool for an airplane pin shaft comprises a bow frame, a screw rod, a ratchet wheel device, a handle and a draw bolt, wherein the ratchet wheel device is arranged in the middle of the top end of the bow frame; the fixing pin is arranged on the bow frame, the side face of the screw rod is provided with a groove matched with the fixing pin along the axis direction, and the fixing pin extends into the groove of the screw rod.

Preferably, the side surface of the pulling bolt is provided with a thread.

Preferably, the ratchet device further comprises a reversing chuck.

Preferably, the bow frame is provided with fixing devices at two ends.

The utility model provides a withdrawal tool for aircraft round pin axle can carry out the round pin axle dismantlement work at different models and positions, and the work action is little, and easy operation is convenient.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic view of the internal structure of the present invention;

shown in the figure: 1-bow rack, 2-screw, 3-ratchet device, 4-handle, 5-bolt, 6-middle shaft, 7-rotary handle, 8-fixed pin, 9-fixing device and 31-reversing chuck.

Detailed Description

To further illustrate the concept of the present invention, the following embodiments of the present invention will be further described with reference to the accompanying drawings:

as shown in fig. 1, the disassembling tool for the airplane pin shaft comprises a bow frame 1, a screw 2, a ratchet device 3, a handle 4, a draw bolt 5, a middle shaft 6, a rotary handle 7 and a fixing pin 8, wherein the ratchet device 3 is arranged in the middle of the top end of the bow frame 1, threads are arranged on the side surface of the screw 2, the ratchet device 3 is sleeved on the screw 2 and movably connected by the threads, the threads can be arranged on the whole body of the screw 2, and can be only arranged at the upper end part of the screw 2, so long as the ratchet device 3 can drive the screw 2 when working; the ratchet wheel device 3 is connected with the handle 4, the screw rod 2 is hollow, the middle shaft 6 is arranged in the screw rod 2, two ends of the middle shaft are fixedly connected with the pull bolt 5 and the rotating handle 7, the pull bolt 5 is positioned at the lower end of the screw rod 2, the pull bolt 5 can be driven to rotate by rotating the rotating handle 7, and the pull bolt 5 is used for connecting a pin shaft to be disassembled; the fixing pin 8 is arranged on the bow frame 1, the side surface of the screw rod 2 is provided with a groove matched with the fixing pin 8 along the axial direction, and the fixing pin 8 extends into the groove of the screw rod. Through shaking the handle 4, can make ratchet 3 rotate and drive screw rod 2 and rotate, nevertheless because screw rod 2 is by fixed pin 8 restriction rotation, screw rod 2 can realize reciprocating under the effect of screw thread to the power of pulling out the round pin axle produces. Wherein, ratchet 3 adopts prior art can realize, and its principle is similar to ratchet spanner after ratchet 3 is connected with handle 4.

In order to enable the pulling bolt 5 and the pin shaft to be combined more tightly and provide better effect, threads can be arranged on the side face of the pulling bolt 5, and the pulling bolt 5 can be meshed with the inner threads of the blind hole at the head of the pin shaft by utilizing the threads.

Meanwhile, the ratchet device 3 is also provided with a reversing chuck 31, so that the screw rod 2 can move in two directions, and the rotation direction of the ratchet is switched by the reversing chuck 31.

In order to adapt to different types and positions of the disassembling tool, fixing devices 9 can be arranged at two ends of the bow frame 1, the fixing devices 9 can be selected according to requirements, pins, rubber and the like can be adopted, and selection is specifically carried out according to the interface condition.

When the bow rack is used, the screw rod 2 is adjusted to an approximate position, then the two ends of the bow rack 1 are erected at an operation position, the screw rod 2 is finely adjusted by using the handle 4 through the ratchet wheel device 3, the pull bolt 5 is moved to a blind hole at the end of the pin shaft, and then the rotating handle 7 is rotated to enable the pull bolt 5 to be tightly combined with the pin shaft. After the pulling bolt 5 is connected with the pin shaft, the reversing chuck 31 is adjusted, the handle 4 is shaken to pull out the screw rod 2, and thus the pin shaft is pulled out. Use the utility model provides a disassembling tool only needs to wave handle 4 and just can demolish the round pin axle, and is easy and simple to handle, dismantles the process and can not cause destruction to aircraft round pin axle, and quality safe and reliable has ensured aircraft flight safety, has that the structure is small and exquisite, simple, portable, and operation and convenient to use are applicable to the arbitrary occasion of dismantling, have greatly improved work efficiency.
