Description

Technical Field

[0001] The utility model belongs to the technical field of turbine cooler maintenance equipment, in particular to a decomposition and assembly device for a turbine cooler. Background Art

[0002] The turbine cooler is an important component of an aircraft and requires regular maintenance and overhaul. The existing repair of turbine coolers lacks a dedicated disassembly and assembly tool. Generally, the turbine cooler is directly clamped and fixed on a vise and then disassembled and assembled using an open-end wrench or other wrench. Specifically, the nut at one end of the turbine cooler rotating shaft is first clamped and fixed on the vise, and the nut at the other end of the rotating shaft is removed using an open-end wrench; then the end of the rotating shaft with the other end is clamped and fixed on the vise, and the other nut that has not been loosened is removed. The existing assembly method is also to clamp the nut at one end of the rotating shaft on the vise, and then use an open-end wrench to tighten the nut at the other end. The main defects of the existing technology are: (1) Directly clamping the rotating shaft on the vise will cause damage to the rotating shaft. If it is not clamped well or the nut is too tight, it is easy to cause the other end or nut on the rotating shaft to slip, resulting in the inability to further disassemble and assemble. (2) When using an open-end wrench to loosen or tighten the nut, the nut may slip, resulting in the inability to further disassemble and assemble or the nut being scrapped. (3) There are many parts inside the turbine cooler. If the clamping angle is not appropriate during the disassembly and assembly process, the parts are easily dislocated and damaged. For example, there is a bushing with a locating pin inside the shell near both ends. When the shell is in a loose state during disassembly or assembly, the locating pin and bushing are easily displaced or fall out, causing damage to the bushing and locating pin, and then damaging the turbine cooler.

[0003] In summary, the existing disassembly and assembly methods of turbine coolers are relatively simple and crude, which not only have low work efficiency, but are also prone to slipping and cannot be effectively disassembled or parts are misplaced, causing damage to the product. Therefore, it is of great significance to design a device that can not only efficiently disassemble and assemble the turbine cooler, but also avoid damage to the turbine cooler and avoid misplacement of parts. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a turbine cooler disassembly and assembly device which has a simple structure, high operation efficiency and no damage to the operation object.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A disassembly and assembly device for a turbine cooler comprises a base, an upper base, a support member, a sleeve and a wrench, wherein the upper base is connected to and installed on the base through the support member, and the base, the support member and the upper base together form a space for accommodating the turbine cooler; a first through hole is provided on the base, and the first through hole cooperates with the shaft end nut of the turbine cooler, and the first through hole can also cooperate with the outer periphery of the sleeve, and the inner periphery of the sleeve cooperates with the rotating shaft of the turbine cooler; a second through hole is provided on the upper base, a slot is provided at the first end of the wrench, and a handle is provided at the second end of the wrench, and the wrench is used to pass through the second through hole and then cooperate with the shaft end nut of the turbine cooler through the slot, and the wrench can rotate relative to the upper base.

[0007] In the above-mentioned disassembly and assembly device for the turbine cooler, preferably, the second end of the wrench is provided with a first adapter portion for cooperating with a torque wrench.

[0008] In the above-mentioned disassembly and assembly device of the turbine cooler, preferably, the second end of the wrench is provided with a first adapter portion and a second adapter portion along the axial direction, and the second adapter portion is used to cooperate with the rotation output end of the motor.

[0009] In the above-mentioned disassembly and assembly device for the turbine cooler, preferably, the handle and the wrench are detachably connected.

[0013] The above-mentioned disassembly and assembly device for the turbine cooler, preferably, the base is further provided with a mounting hole, and the mounting hole is used to fix the disassembly and assembly device on a workbench.

[0014] Compared with the prior art, the advantages of the utility model are:

[0015] (1) The utility model discloses a disassembly and assembly device for a turbine cooler. The first through hole and the wrench are provided on the base and the upper seat, and the shape of the through hole and the shape of the nut on the shaft end of the turbine cooler are completely matched. The utility model also designs a sleeve whose outer periphery matches with the first through hole and whose inner periphery matches with the rotating shaft of the turbine cooler. The wrench, the sleeve and the support formed by the base, the upper seat and the support member can prevent the risk of slipping and the resulting damage during disassembly and assembly, thereby overcoming the shortcomings of the prior art such as unreasonable clamping, easy damage to the product and low work efficiency. Moreover, the disassembly and assembly device is in a vertical layout as a whole, which can make the clamping and fixing of the turbine cooler more reliable and stable. Most importantly, the turbine cooler is clamped vertically in an axial direction during operation of the vertical disassembly and assembly device, and the bushings and locating pins in a loose state during disassembly or assembly are always facing upwards, and the locating pins will not shift after the bushings are installed, which solves the problem that the clamping and fixing angle of the turbine cooler is not appropriate during operation of the prior art, which causes the bushings, locating pins and other spare parts to shift and fall out before the turbine cooler is tightened, causing damage and then damaging the turbine cooler. In summary, the device of the utility model can not only efficiently disassemble and assemble the turbine cooler, but also prevent damage to the turbine cooler during the disassembly and assembly process.

[0016] (2) In the disassembly and assembly device of the turbine cooler of the utility model, since the socket and the wrench are detachable, the disassembly and assembly of turbine coolers of different models or the same type of rotating products can be applied by replacing the socket and the wrench of different shapes, making the design more universal.

[0017] (3) Usually, there are requirements for tightening torque when assembling a turbine cooler, especially for aircraft turbine coolers, which require strict monitoring of the tightening torque during assembly. The disassembly and assembly device for the turbine cooler of the utility model designs the end of the wrench into an outer hexagonal shape that is suitable for the torque wrench socket, so that the device can also measure the torque of tightening the nut after completing the assembly, and can also be adapted to an electric tool through a conversion joint for disassembling nuts with excessive tightening force.

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Figures 1 to 6 As shown, the disassembly and assembly device of the turbine cooler of this embodiment includes a base 1, an upper base 2, a support member 3, a sleeve 4 and a wrench 5. The upper base 2 is connected and installed on the base 1 through the support member 3. The base 1, the support member 3 and the upper base 2 together form a space for accommodating the turbine cooler 6; a first through hole 11 is provided on the base 1, and the first through hole 11 cooperates with the shaft end nut 62 of the turbine cooler 6. The first through hole 11 can also cooperate with the outer periphery of the sleeve 4, and the inner periphery of the sleeve 4 cooperates with the rotating shaft 61 of the turbine cooler 6; a second through hole 21 is provided on the upper base 2, a slot 51 is provided at the first end of the wrench 5, and a handle 52 is provided at the second end of the wrench 5. The wrench 5 is used to pass through the second through hole 21 and then cooperate with the shaft end nut 62 of the turbine cooler 6 through the slot 51, and the wrench 5 can rotate relative to the upper base 2.

[0028] The disassembly and assembly device of this embodiment can save time and effort to loosen the nuts at both ends of the rotating shaft 61, and efficiently disassemble the turbine cooler 6. It can also save time and effort to tighten the nuts at both ends of the rotating shaft 61 (i.e., the nuts at the shaft ends), and efficiently assemble the turbine cooler 6. It can also prevent damage to the turbine cooler 6 during the disassembly and assembly process. The overall structure of the device adopts a vertical layout, which can make the clamping and fixing of the turbine cooler 6 more reliable and stable. Most importantly, the turbine cooler 6 is clamped vertically in the axial direction during operation of the vertical layout disassembly and assembly device. The bushing 7 and positioning pin 71 in a loose state during disassembly or assembly are always facing upwards, and the positioning pin 71 will not shift after the bushing 7 is installed. This solves the problem that the clamping and fixing angle of the turbine cooler 6 is not suitable during operation of the prior art, which causes the bushing 7, positioning pin 71 and other spare parts to shift and fall out easily before the turbine cooler 6 is tightened, causing damage and then damaging the turbine cooler 6. Figure 7 As shown, there is a bushing 7 with a positioning pin 71 inside both ends of the shell near the turbine cooler 6.

[0029] Before use, the disassembly and assembly device is first fixed on the workbench through the base 1. When disassembling, first fix the nut at one end of the turbine cooler 6 on the base 1 (without the sleeve), and fix the nut at the other end with the spanner 5. Turn the spanner 5 to loosen the nut. When disassembling, if the nut at one end has been loosened and the nut at the other end is still tight, install the dedicated sleeve 4 on the base 1, then fix the rotating shaft 61 on the sleeve 4, and finally loosen the nut at the other end.

[0030] Specifically, since the inner circumferential shape of the first through hole 11 completely matches the outer shape of the nut 62 at the shaft end of the turbine cooler 6, the turbine cooler 6 to be disassembled is vertically placed in the space surrounded by the base 1, the support member 3 and the upper seat 2, so that one end of the shaft of the turbine cooler 6 and its nut are embedded in the first through hole 11 and fixed; the first end of the wrench 5 is inserted into the second through hole 21, and since the first end of the wrench 5 is designed with a slot 51 whose shape completely matches the outer shape of the nut 62 at the shaft end of the turbine cooler 6, the slot 51 is nested with the other end of the shaft of the turbine cooler 6 and its nut, thereby fixing the turbine cooler 6 in place by clamping the nuts at both ends of the shaft. On the disassembly and assembly device, turn the wrench 5 to loosen the nuts at both ends. If the nut at one end is loose and the other end is still tight, the turbine cooler 6 can be turned up and down along the axial direction, and the sleeve 4 is embedded in the first through hole 11 and fixed relatively to the first through hole 11 in the axial direction. Since the inner circumferential shape of the sleeve 4 completely fits the outer shape of the rotating shaft 61 of the turbine cooler 6, it can be used for clamping and fixing the rotating shaft 61 of the turbine cooler 6. One end of the rotating shaft 61 of the turbine cooler 6 with the nut removed is embedded in the sleeve 4, and then the slot 51 at the first end of the wrench 5 is nested with the unloosened shaft end nut 62, so as to turn the handle 52 to loosen it and disassemble it.

[0031] During assembly, the nuts at both ends of the turbine cooler 6 are fixed to the base 1 (without a sleeve) and the wrench 5 respectively, and the nuts at both ends of the rotating shaft 61 are tightened by rotating the wrench 5 .

[0032] In this embodiment, the second end of the wrench 5 is provided with a first adapter 53 for cooperating with a torque wrench, so that the device of this embodiment is not only suitable for disassembly and assembly of the turbine cooler 6, but also can measure the tightening torque of the nuts at both ends. The first adapter 53 is an outer hexagonal end, which can be adapted to a torque wrench, and the tightening torque can be measured while tightening the nut. When the tightening torque of the nuts at both ends is too large to be disassembled by rotating the wrench 5, the outer hexagonal end can also be adapted to an electric impact tool through an adapter to disassemble the nut.

[0033] Of course, in other embodiments, the second end of the wrench 5 can be provided with a first adapter portion 53 and a second adapter portion along the axial direction at the same time. The second adapter portion can directly cooperate with the rotation output end of the electric impact tool without the need for an adapter, which is more convenient to use.

[0034] In this embodiment, the handle 52 is a rod such as a round bar that is radially penetrated through the second end of the wrench 5. A mounting hole for inserting the rod is radially provided on the second end of the wrench 5. The handle 52 is detachably connected to the wrench 5. The handle 52 is designed to be detachably connected, which is convenient for storage and replacement with a torque wrench or an electric impact tool. That is, when the torque wrench or the electric impact tool is used, the handle 52 does not need to be installed.

[0035] In this embodiment, the base 1 and the support member 3 are detachably connected, and the support member 3 and the upper seat 2 are detachably connected.

[0036] In this embodiment, the base 1 and the support member 3 are fixed by means of a gasket 12 and a bolt 13 , and the support member 3 and the upper seat 2 are fixed by means of a gasket 12 and a bolt 13 .

[0037] In this embodiment, the base 1 is further provided with a mounting hole, and the mounting hole is used to fix the disassembly and assembly device on a workbench.

Any technician familiar with the art can use the above disclosed technical content to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
