Description

Technical Field

[0001] The utility model relates to the technical field of guide rail decomposition, in particular to a combined tool for decomposing special-shaped spatial guide rails. Background Art

[0002] During wheel assembly repairs, it's common to find corrosion, indentations, pits, and loss of surface treatment on the wheel rails. When these defects occur, the rails must be removed and repaired or replaced as required by the repair documentation. The rails contact the brake discs, transmitting braking force to the wheel assembly and achieving braking. Therefore, the quality of the rails directly impacts aircraft safety during landing, parking, and towing.

[0003] Normally, the guide rails are fixed to the wheel hub by screws, and the screws are prevented from loosening by applying epoxy glue on the threads. A wheel assembly is generally equipped with 9 guide rails, totaling 18 screws. Therefore, when removing the guide rails, the screws must be disassembled and the epoxy glue must be softened. This process requires a lot of force, and the space for disassembling the screws is very small (see the attached manual). Figure 2 、 3 This leads to low efficiency, inconvenience in construction operations and other problems.

[0004] Based on the above reasons, the utility model designs a combined tooling for decomposing special-shaped spatial guide rails, which meets the needs of decomposing the guide rails on the wheel assembly, while reducing costs, saving time and effort, improving work efficiency, and ensuring the normal processing and maintenance of the guide rails. Summary of the Invention

[0005] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a combined tooling for decomposing special-shaped spatial guide rails to meet the needs of decomposing the guide rails on the wheel assembly, while reducing costs, saving time and effort, improving work efficiency, and ensuring the normal processing and maintenance of the guide rails.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a combined tool for disassembling special-shaped spatial guide rails, including a ratchet wrench, a socket, a flat-head cutter, a miniature jack, a connecting pipe and a quick-release joint. The bottom of the ratchet wrench is against the top rod of the miniature jack, the top hexagonal end of the ratchet wrench is connected to the socket, and the socket is connected to the flat-head cutter.

[0007] The push rod of the miniature jack is connected with the booster rod of the miniature jack through a quick-release joint and a connecting pipe.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] The utility model installs a slotted head cutter on the ratchet wrench so that it can reach into the narrow area of ​​the screw inside the guide rail, meet the needs of decomposing screws with large tightening torque in an anisotropic space, and realize the decomposition of the guide rail more easily and conveniently. At the same time, all parts are easy to source, easy to assemble, simple to process, low in cost, with great scalability, and suitable for the assembly of other similar parts.

[0013] 1 is a ratchet wrench, 2 is a socket, 3 is a slotted screwdriver, 4 is a mini jack, 5 is a connecting pipe, 6 is a quick-release connector, 7 is a screw, and 8 is a guide rail. DETAILED DESCRIPTION

[0014] The present invention will now be further described with reference to the accompanying drawings.

[0015] See also Figures 1 to 3 The utility model provides a combined tool for decomposing special-shaped spatial guide rails, including a ratchet wrench 1, a socket 2, a flat head cutter 3, a miniature jack 4, a connecting pipe 5 and a quick-release joint 6. The bottom of the ratchet wrench 1 is against the top rod of the miniature jack 4, the top hexagonal end of the ratchet wrench 1 is connected to the socket 2, and the socket 2 is connected to the flat head cutter 3.

[0016] The push rod of the miniature jack 4 is connected to the force rod of the miniature jack 4 through a quick-release joint 6 and a connecting pipe 5 .

[0017] Working principle:

[0018] The utility model does not require much debugging when in use. Figure 2-3 As shown, the guide rail 8 is located on one side of the wheel assembly, and the inner space is relatively narrow. It can be seen that there are several screws 7 distributed on the guide rail 8. It is necessary to first install the sleeve 2 on the ratchet wrench 1, and then install the hexagonal end of the flat-blade bit 3 in the sleeve 2, so that the flat-blade bit 3 and the flat-blade groove of the screw 7 are completely fitted. One end of the sleeve 2 is sleeved on the square head of the ratchet wrench 1 to connect the flat-blade bit 3 and the ratchet wrench 1. When the ratchet wrench 1 is rotated, the flat-blade bit 3 is rotated at the same time, causing the screw 7 to rotate accordingly.

[0019] Secondly, place the push rod of the micro jack 4 under the ratchet wrench 1 to ensure that the head of the ratchet wrench 1 is in the center of the push rod of the micro jack 4. The micro jack 4 is combined with the ratchet wrench 1 to press the ratchet wrench 1 to prevent the slotted cutter head 3 from slipping out of the slotted groove 7 of the screw.

[0020] Finally, press the micro jack 4 so that the push rod of the micro jack 4 presses the ratchet wrench 1 tightly. At this time, it is necessary to ensure that the slotted cutter head 3 is vertical.

[0021] Add a force rod to the wrench end of ratchet wrench 1 and apply force counterclockwise to ratchet wrench 1. During the counterclockwise rotation, screw 7 will be screwed out upward. At this time, it is necessary to appropriately release the pressure from the jack to allow screw 7 to continue to be screwed out upward until the jack is completely relieved. At this point, the epoxy glue on the thread of screw 7 has completely loosened, and the torque required to disassemble screw 7 is very small. After removing micro jack 4 and the force rod, screw 7 can be continued to be unscrewed.

[0022] The above are only preferred embodiments of the present invention and are intended to help understand the method and core concept of this application. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be pointed out that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.

[0023] The utility model comprehensively solves the shortcomings of the prior art, such as the time-consuming and labor-intensive process of softening the epoxy glue required for fixing the guide rail to the wheel hub by applying epoxy glue, and the small structural space for disassembling the screws affecting the operating efficiency. By installing a flat-head screwdriver on the ratchet wrench, it can reach into the narrow area of ​​the screws inside the guide rail, so as to meet the requirements of decomposing screws with large tightening torque in an anisotropic space, and the guide rail can be disassembled more easily and conveniently. At the same time, all components are easily sourced, assembled conveniently, processed simply, and have low cost. It has large scalability and is suitable for the assembly of other similar parts.
