Description

Technical Field

[0001] This application relates to the field of assembly and manufacturing technology, and in particular to a disassembly and positioning tooling. Background Technology

[0002] The brake cooling fan consists of two housings, front and rear, with wires connecting them. The rear housing contains a compressed spring and bearing. Because the spring in the rear housing is compressed during assembly, disassembly and reassembly require applying pressure to the rear housing to counteract the spring's elasticity before the screws and nuts at the connection between the front and rear housings can be removed. In practice, these steps cannot be completed by one person alone. Typically, one person is needed to hold the front housing and apply pressure to the rear housing, while another person handles the screws and nuts at the connection, increasing labor costs. Utility Model Content

[0003] This application discloses a disassembly and assembly positioning fixture. By configuring a first positioning component to fix the part to be disassembled and assembled, and by using the operating mechanism and movable positioning component in the second positioning component to press the part to be disassembled and assembled, it is convenient for operators to carry out subsequent disassembly and assembly steps.

[0004] To achieve the above objectives, this application discloses a disassembly and positioning fixture, including a base, a first positioning component, and a second positioning component. The first positioning component is disposed on the base and is used to position the first housing; the second positioning component includes an operating mechanism and a movable positioning member, the operating mechanism being movably disposed on the base and connected to the movable positioning member, the movable positioning member being used to position the second housing.

[0005] The operating mechanism can drive the movable positioning component to move the second housing towards the first positioning component and lock it to the target position under the action of external force, so as to counteract the pre-tightening force of the elastic pre-tightening mechanism in the component to be disassembled, thereby enabling the first housing and the second housing to be assembled or disassembled.

[0006] In one possible implementation, the first positioning component includes:

When the component to be disassembled is placed in the disassembly and assembly positioning fixture, the first preset axis coincides with the central axis of the component to be disassembled.

[0008] Multiple limiting members are provided on the multiple mounting members in a corresponding manner. The limiting members are movably connected to the mounting members. When the limiting member moves to the locked position, the limiting member limits the first housing to restrict the first housing from moving in the horizontal and vertical directions. When the limiting member moves to the unlocked position, the limiting member releases the limiting member from the first housing.

At least a portion of the connecting part extends into the mounting cavity. The first positioning component also includes a fastener that passes through the connecting part and is connected to the threaded part.

[0013] Wherein, the fastener is tightly fitted with the threaded portion to drive the limiting portion to move into the notch and limit it to the notch, and the limiting portion can abut against the first housing so that the limiting member is in the locked position; the fastener is loosely fitted with the threaded portion to drive the limiting portion out of the notch, and the limiting portion moves away from the first housing so that the limiting member is in the unlocked position.

[0014] In one possible implementation, the first positioning component further includes:

[0015] An elastic element is disposed within the mounting cavity, with its two ends respectively abutting against the connecting portion and the cavity wall of the mounting cavity;

[0016] Along the axial direction of the mounting component, the length of the notch is less than the thread engagement stroke between the threaded portion and the fastener.

[0017] In one possible implementation, the operating mechanism includes:

[0018] A handle rod, one end of which is movably disposed on the base;

[0019] A pressure rod, one end of which is movably disposed on the base;

[0020] A connecting rod, one end of which is movably connected to the handle rod, and the other end of which is movably connected to the pressure rod.

[0021] In one possible implementation, the handle lever is provided with a through-hole, and the pressure rod passes through the through-hole and connects to the base;

[0022] The handle rod is connected to the first mounting hole of the base, and the pressure rod is connected to the second mounting hole of the base. In the horizontal direction, the second mounting hole is farther away from the first positioning component than the first mounting hole.

[0023] In one possible implementation, the base includes:

[0024] Base plate;

[0025] A support member is provided on the base plate, and the operating mechanism is movably connected to the support member. The first mounting hole and the second mounting hole are provided on the support member.

[0027] The first component is slidably disposed on the pressure bar;

[0028] A pressure cap, connected to the first component, is used to abut against the second housing.

[0029] In one possible implementation, the side of the gland that connects to the first component is provided with a mating groove, which is used to connect the first component.

[0030] Compared with the prior art, the beneficial effects of this application are: the first positioning component fixes the first housing of the part to be disassembled, and the second positioning component counteracts the pre-tightening force of the elastic pre-tightening mechanism in the second housing of the part to be disassembled, thereby achieving the purpose of using disassembly and assembly positioning fixtures to replace manual positioning and fixing of the part to be disassembled, reducing labor costs and improving work efficiency.

[0047] Please refer to Figures 1 to 2 This application provides a disassembly and assembly positioning fixture 1, which is used to disassemble or assemble a component A to be disassembled or assembled. The component A to be disassembled or assembled consists of a first housing A1 and a second housing A2, which are connected by an elastic pre-tightening mechanism and a fastening connection assembly.

[0048] The disassembly and assembly positioning fixture 1 is particularly suitable for scenarios where disassembly and assembly require overcoming preload forces. Specifically, the part to be disassembled or assembled, A, can be a brake cooling fan from an Airbus aircraft. Of course, the part to be disassembled or assembled, A, can also be other workpieces with a housing having an elastic preload mechanism, such as automotive parts (gearbox clutch cover, battery pack housing), electronic equipment (explosion-proof electrical housing), etc. This application embodiment does not specifically limit this. The following description uses the brake cooling fan from an aircraft as an example of the part to be disassembled or assembled, A.

[0049] For example, the brake cooling fan has a first housing A1 and a second housing A2 that are movable relative to each other. A wire, a fastening connection assembly, and an elastic pre-tightening mechanism are disposed between the first housing A1 and the second housing A2. When the component to be disassembled, A, is assembled, the wire between the first housing A1 and the second housing A2 is taut, while the elastic pre-tightening mechanism remains compressed. At this time, a continuous pre-tightening force exists in the axial direction of the first housing A1 and the second housing A2. This pre-tightening force is maintained by the fastening action of the fastening connection assembly, thereby ensuring that the first housing A1 and the second housing A2 are relatively fixed. Therefore, when disassembling the brake cooling fan, sufficient clamping force must first be applied to the brake cooling fan to balance the elastic tension of the elastic pre-tightening mechanism. Only after this pre-tightening force is completely neutralized can the fastening connection assembly connecting the first housing A1 and the second housing A2 be disassembled.

[0050] The disassembly and assembly positioning fixture 1 includes a base 10, a first positioning component 20, and a second positioning component 30. The first positioning component 20 is located on the base 10 and is used to position the first housing A1. The second positioning component 30 includes an operating mechanism 301 and a movable positioning element 302. The operating mechanism 301 is movably mounted on the base 10 and connected to the movable positioning element 302, which is used to position the second housing A2. Under operator control, the operating mechanism 301 can drive the movable positioning element 302 to move the second housing A2 closer to the first positioning component 20 and lock it in the target position. This counteracts the pre-tightening force of the elastic pre-tightening mechanism within the component A to be disassembled, thereby allowing the first housing A1 and the second housing A2 to be assembled or disassembled.

[0051] When disassembling or assembling part A, first place the first housing A1 of part A on the base 203 of the disassembly and assembly positioning fixture 1. When it is determined that the position of the movable positioning member 302 of the second positioning component 30 is on the axis of the second housing A2, operate the operating mechanism 301 of the second positioning component 30 to control the movable positioning member 302 to move to the target position and press down the second housing A2 so as to assemble or disassemble part A.

[0052] The target position is the position of the second housing A2 after it undergoes a slight displacement under the pressure of the movable positioning member 302. When the second housing A2 is in the target position, the relative displacement between the second housing A2 and the first housing A1 can offset the pre-tightening deformation of the elastic pre-tightening mechanism. The elastic pre-tightening mechanism in the component A to be disassembled and assembled, which was originally in a compressed state, reaches the force balance point, and the axial load borne by the fastening connection assembly is released so that the fastening connection assembly can be disassembled and assembled in the future.

[0053] Similarly, to assemble component A to be disassembled, the first housing A1 can be fixed to the first positioning component 20 first. Then, the operating mechanism 301 controls the movable positioning component 302 to move the second housing A2 to the target position. In this position, the preload of the elastic preload mechanism is fully balanced, and the fastening connection component can be easily installed. After fastening is completed, the operating mechanism 301 is released, and the movable positioning component 302 releases the restriction on the second housing A2, allowing the elastic preload mechanism to return to the preset compression state, thereby achieving the designed preload force between the first housing A1 and the second housing A2.

[0054] Thus, the disassembly and assembly positioning fixture 1 provided in this application embodiment fixes the first housing A1 of the part to be disassembled and assembled A through the first positioning component 20, and offsets the pre-tightening force of the elastic pre-tightening mechanism in the second housing A2 of the part to be disassembled and assembled A through the second positioning component 30, thereby achieving the purpose of using the disassembly and assembly positioning fixture 1 to replace manual positioning and fixing of the part to be disassembled and assembled A, reducing labor costs and improving work efficiency.

[0055] In some embodiments, such as Figure 3 As shown, the first positioning component 20 of the disassembly and assembly positioning fixture 1 includes multiple mounting parts 201. Each mounting part 201 is fixed relative to the base 10, and the multiple mounting parts 201 are arranged around a first preset axis. When the part A to be disassembled is placed in the disassembly and assembly positioning fixture 1, the first preset axis coincides with the central axis of the part A to be disassembled.

[0056] The first positioning component 20 of the disassembly and assembly positioning fixture 1 includes multiple limiting members 202. The multiple limiting members 202 are correspondingly provided on multiple mounting members 201. The limiting members 202 are movably connected to the mounting members 201. When the limiting member 202 moves to the locked position, the limiting member 202 limits the first housing A1 to restrict the first housing A1 from moving in the horizontal and vertical directions. When the limiting member 202 moves to the unlocked position, the limiting member 202 is released from the first housing A1.

[0057] Specifically, multiple mounting components 201 can be evenly arranged around the first preset axis. When the first housing A1 is placed on the base 203 of the disassembly and positioning fixture 1, the central axis of the first housing A1 coincides with the first preset axis. Each mounting component 201 is provided with a corresponding limiting component 202. The limiting component 202 is used to fix the first housing A1 in the locked state, ensuring that the central axis of the first housing A1 coincides with the first preset axis, thereby achieving the purpose of limiting the vertical direction of the first housing A1.

[0058] Accordingly, under the combined action of the multiple mounting parts 201 and the corresponding multiple limiting parts 202 included in the first positioning component 20, the first housing A1 of the part to be disassembled A can be limited in the horizontal and vertical directions, preventing the first housing A1 from moving in the vertical direction, thus preparing for the subsequent disassembly and assembly of the second housing A2.

[0059] In some embodiments, the first positioning component 20 of the disassembly and positioning fixture 1 further includes a base 203. The base 203 is disposed on the base 10 and includes a mounting groove 204 for limiting the first housing A1. The mounting groove 204 has a first central axis, and a plurality of mounting members 201 are disposed on the base 203.

[0060] Furthermore, such as Figure 4 As shown, the first positioning component 20 also includes a base 203, which has a mounting groove 204. The first central axis of the mounting groove 204 coincides with a first preset axis. The mounting groove 204 is used to pre-position the first housing A1 on the base 203 to prevent the first housing A1 from moving in the horizontal direction. The base 203 has holes in the same number as the mounting members 201 for mounting the mounting members 201.

[0061] The mounting groove 204 on the base 203 is used to pre-position the first housing A1, which makes it easier to fix the first housing A1 with the limiting member 202 later. This eliminates the step of adjusting the first housing A1 to make the axis of the first housing A1 coincide with the first central axis when fixing the first housing A1 with the limiting member 202, which simplifies the operation steps of the operator and improves the work efficiency of the operator.

[0062] In some embodiments, such as Figure 5 As shown, the mounting part 201 of the disassembly and positioning fixture 1 is provided with a mounting cavity 205 and a threaded part 206 communicating with the mounting cavity 205. The side wall of the mounting part 201 is provided with a notch 207 communicating with the mounting cavity 205, and a fastener is provided in the mounting cavity 205.

[0063] Please refer to Figure 6 The limiting member 202 of the disassembly and positioning fixture 1 includes a limiting part 2021 and a connecting part 2022 that are bent and connected. The limiting part 2021 is used to limit the first housing A1. At least a portion of the connecting part 2022 extends into the mounting cavity 205. The first positioning assembly 20 also includes a fastener that passes through the connecting part 2022 and is connected to the threaded part 206.

[0064] Furthermore, the fastener is tightly fitted with the threaded portion 206 to move the limiting portion 2021 into the notch 207 and limit it against the notch 207. The limiting portion 2021 can abut against the first housing A1 to put the limiting member 202 in a locked position (e.g., Figure 3 The position of the middle limiting member 202a); the fastener loosely engages with the threaded portion 206 to move the limiting portion 2021 out of the notch 207, and the limiting portion 2021 moves away from the first housing A1, so that the limiting member 202 is in the unlocked position (e.g., Figure 3 (The position of the middle limit component 202b).

[0065] Specifically, the mounting cavity 205 of the mounting member 201 and the connecting portion 2022 of the limiting member 202 can cooperate with each other so that a portion of the connecting portion 2022 of the limiting member 202 extends into the mounting cavity 205. A fastener disposed in the mounting cavity 205 cooperates with a threaded portion 206 located at the bottom of the mounting cavity 205 and communicating with the mounting cavity 205. At the end of the mounting member 201 that cooperates with the limiting member 202, the side wall of the mounting member 201 facing the first preset axis is provided with a notch 207 that cooperates with the limiting portion 2021 of the limiting member 202. When the limiting part 2021 of the limiting member 202 is in the notch 207, the limiting member 202 is in the locked position. At this time, it is only necessary to tighten the fastener, which is provided in the mounting cavity 205 and passes through the connecting part 2022, and the threaded part 206 to make the limiting member 202 abut against the first housing A1, so as to achieve the purpose of limiting the first housing A1 in the vertical direction. After the installation and removal of the part A to be disassembled is completed, the fastener and the threaded part 206 are loosened, and the limiting part 2021 is released from the notch 207 of the mounting member 201. At this time, the limiting part 2021 is rotated away from the first housing A1 to release the vertical limitation on the first housing A1. The notch 207 of the mounting member 201 and the fastener work together to ensure that the limiting member 202 will not rotate when it is in the locked position, which reduces the difficulty of limiting the first housing A1 in the vertical direction, and also reduces the number of operation steps for operators, thereby improving the work efficiency of operators.

[0066] In some embodiments, the first positioning component 20 of the disassembly and assembly positioning fixture 1 further includes an elastic element. The elastic element is disposed within the mounting cavity 205, and its two ends abut against the connecting portion 2022 and the cavity wall of the mounting cavity 205, respectively.

[0067] Furthermore, along the axial direction of the mounting part 201, the length of the notch 207 is less than the thread engagement stroke between the threaded portion 206 and the fastener.

[0068] Specifically, the length of the notch 207 of the mounting part 201 is less than the thread engagement stroke between the threaded part 206 and the fastener. This ensures that the fastener and the threaded part 206 do not disengage. Using the elastic element provided in the mounting cavity 205, the limiting part 202 is ejected from the mounting cavity 205 through the loose engagement between the fastener and the threaded part 206. This allows the operator to adjust the direction of the limiting part 2021 of the limiting part 202, reducing the operator's operation steps and thus improving the operator's work efficiency.

[0069] In some embodiments, the operating mechanism 301 of the disassembly and positioning fixture 1 includes a handle 3011. One end of the handle 3011 is movably disposed on the base 10.

[0070] The operating mechanism 301 of the disassembly and positioning fixture 1 includes a pressure rod 3012. One end of the pressure rod 3012 is movably mounted on the base 10.

[0071] The operating mechanism 301 of the disassembly and positioning fixture 1 includes a connecting rod. One end of the connecting rod is movably connected to the handle rod 3011, and the other end of the connecting rod is movably connected to the pressure rod 3012.

[0072] Specifically, the second positioning component 30 includes an operating mechanism 301, which mainly comprises a handle 3011, a pressure rod 3012, and a connecting rod. One end of the handle 3011 and one end of the pressure rod 3012 are movably positioned at different locations on the base 10. Both ends of the connecting rod are movably connected to the middle portions of the handle 3011 and the pressure rod 3012, respectively, thus forming a four-bar linkage structure. When pressure is applied to the second housing A2, simply pushing the handle 3011 towards the second housing A2 achieves the purpose of applying pressure to the second housing A2.

[0073] In some embodiments, the handle 3011 of the operating mechanism 301 is provided with a through-hole 3013, and the pressure rod 3012 passes through the through-hole 3013 and is connected to the base 10.

[0074] Furthermore, the handle rod 3011 is connected to the first mounting hole 1023 of the base 10, and the pressure rod 3012 is connected to the second mounting hole 1024 of the base 10. In the horizontal direction, the second mounting hole 1024 is farther away from the first positioning component 20 than the first mounting hole 1023.

[0075] Specifically, the base 10 is provided with a first mounting hole 1023 and a second mounting hole 1024 at the same horizontal position. The handle rod 3011 is connected to the base 10 through the first mounting hole 1023 near the first positioning component 20, and the pressure rod 3012 is connected to the handle rod 3011 through the through hole 3013 via the second mounting hole 1024. In this way, sufficient external force can be applied to and held on the second housing A2 in a relatively labor-saving manner, without the need for an operator to apply external force to the second housing A2. This allows one operator to independently complete the disassembly and assembly process of the component A to be disassembled, saving labor costs and improving the operator's work efficiency.

[0076] In some embodiments, the base 10 of the disassembly and positioning fixture 1 includes a base plate 101 and a support member 102. The support member 102 is disposed on the base plate 101, the operating mechanism 301 is movably connected to the support member 102, and a first mounting hole 1023 and a second mounting hole 1024 are disposed on the support member 102.

[0077] Specifically, the base 10 of the support member 102 and the first positioning component 20 is disposed on the base plate 101, and the operating mechanism 301 of the second positioning component 30 is disposed on the support member 102. Further, the support member 102 may include a support portion 1021 and a fixing portion 1022. The support portion 1021 is disposed on the base plate 101, and the fixing portion 1022 is disposed on the support portion 1021. The second positioning component 30 is movably connected to the fixing portion 1022. The height of the support portion 1021 is determined according to the height of the component A to be disassembled or assembled, the purpose of which is to ensure that the second positioning component 30 is at a suitable height, thereby making it easier for the operator to apply external force to the component A to be disassembled or assembled through the second positioning component 30, reducing the operator's workload and improving the operator's work efficiency.

[0078] In some embodiments, the movable positioning member 302 of the disassembly and assembly positioning fixture 1 includes a first member 3021, which is slidably disposed on the pressure rod 3012.

[0079] The movable positioning component 302 of the disassembly and assembly positioning fixture 1 includes a pressure cover 3022, which is connected to the first component 3021 and is used to abut against the second housing A2.

[0080] Specifically, the disassembly and assembly positioning fixture 1 mainly applies pressure to the second housing A2 through the movable positioning component 302. The movable positioning component 302 includes a first component 3021 and a pressure cover 3022. The pressure cover 3022 is connected to the first component 3021 and is located below the pressure rod 3012. The first component 3021 is disposed on the pressure rod 3012 and can slide on the pressure rod 3012 to adjust the position of the movable positioning component 302. This ensures that the external force applied to the second housing A2 through the pressure cover 3022 is distributed more evenly on the second housing A2, ensuring that the second housing A2 is subjected to uniform force during disassembly and assembly, ensuring the quality of disassembly and assembly, and reducing damage to the parts of the component A to be disassembled and assembled.

[0081] In some embodiments, please refer to Figure 7 The pressure cap 3022 of the disassembly and positioning fixture 1 is provided with a mating groove 3023 on the side that is connected to the first component 3021. The mating groove 3023 is used to connect the first component 3021.

[0082] Specifically, the pressure cover 3022 of the disassembly and positioning fixture 1 is provided with a mating groove 3023. The mating groove 3023 is used to connect with the first component 3021 to form a movable positioning component 302. The pressure cover 3022 can slide on the pressure rod 3012 with the first component 3021, so that the force applied to the second housing A2 can be adjusted more flexibly, so that the force applied by the pressure cover 3022 to the second housing A2 can be evenly distributed on the force-bearing surface of the second housing A2, thereby improving the disassembly and assembly quality.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
