Description

Technical Field

[0001] This utility model belongs to the field of aerospace technology, and specifically relates to a disassembly and assembly structure for precision machining tools in aerospace applications. Background Technology

[0002] The aerospace industry demands extremely high precision and quality in the machining of components. As a critical component that directly impacts the workpiece, the ease, stability, and precision of the tooling assembly and disassembly process directly affect machining efficiency and product quality. Aerospace components often utilize difficult-to-machine materials such as titanium alloys, high-temperature alloys, and carbon fiber reinforced composites. These materials possess high strength, high hardness, and strong wear resistance, posing stringent challenges to the cutting performance and durability of the tools, resulting in a much higher tool replacement frequency than in ordinary machining.

[0003] In existing technology, during tool disassembly, the tool holder is first inserted into the tool disassembly table, where a notch is used to axially limit and fix the tool holder. Then, the nut on the tool holder is rotated, and after the nut is removed from the tool holder, the collet and the tool can be separated from the nut in sequence, thus achieving tool disassembly. However, rotating and removing the nut requires the use of a large wrench, which is inconvenient and reduces the efficiency of tool installation and disassembly. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a disassembly and assembly structure for precision machining tools in aerospace applications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an aerospace precision machining tool disassembly and assembly structure, comprising a base, a tool disassembly ring and a shift shell sequentially provided on the top of the base, symmetrical contact elements provided on the inner side of the shift shell, a screw and a guide rod respectively provided on both sides inside the shift shell, threaded blocks fixedly connected to one end of the contact element on the surfaces of both ends of the screw, and guide blocks fixedly connected to the other end of the contact element on both ends of the surface of the guide rod, a rotating gear I fixedly sleeved on the surface of the shift shell, a rotating gear II meshing on the surface of the rotating gear I, and a shaft II fixedly sleeved inside the rotating gear II.

[0006] Preferably, mounting plates that are bolted to the base are fixedly installed on both sides of the blade removal ring, and symmetrical protrusions are fixedly installed on the top of the blade removal ring.

[0007] Preferably, the screw and the moving shell are rotatably connected to each other via bearings, and the guide rod and the moving shell are fixedly connected to each other.

[0008] Preferably, a rotary motor is fixedly installed inside the movable housing, and a shaft is fixedly connected to the output end of the rotary motor via a coupling.

[0009] Preferably, a bevel gear is fixedly sleeved at one end of the shaft, and a bevel gear two, which is fixedly sleeved with the screw, meshes with the surface of the bevel gear one.

[0010] Preferably, the surface of the movable shell is rotatably fitted with a sleeve located at the bottom of a rotating gear via a bearing, and a support is fixedly installed on the top of the sleeve.

[0011] Preferably, a second rotating motor is fixedly installed at the bottom of the support member, and the output end of the second rotating motor is fixedly connected to the second shaft through a coupling.

[0012] Preferably, an electric telescopic rod is embedded in the top of the base, and a connector is fixedly installed at the output end of the electric telescopic rod, with the connector and the support being fixedly connected to each other.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. In this utility model, the operator first aligns the notch at the bottom of the external tool handle with the protrusion, achieving axial positioning of the tool handle through mechanical locking. Then, the electric telescopic rod is activated, and when the contact element is adjusted to the same level as the nut on the tool handle surface, the first rotating motor is run, causing the contact element to engage with the nut. Subsequently, constant force clamping is achieved through closed-loop control of the first rotating motor, avoiding thread damage to the nut caused by traditional wrench assembly and disassembly, thus reducing thread wear. This design also facilitates the use of different sized tool handles and nuts, increasing the device's compatibility and adaptability, and providing convenient and flexible adjustment.

[0015] 2. After the nut is clamped and fixed, the second rotating motor is started, driving the movable housing to rotate at a constant speed. The rotation direction is adjusted and matched according to the tool's disassembly or installation. When the torque and number of rotations are reached, the nut and the tool holder's threads are unscrewed and separated. This setting enables rapid disassembly and separation of the tool holder and nut, breaking through the efficiency and precision bottlenecks in the disassembly and assembly of aerospace precision tools.

[0016] 3. After the nut is removed, the electric telescopic rod operates again, moving the housing and nut upwards to expose the collet structure inside the tool holder. This facilitates the separation and disassembly of the collet and the tool by the operator. From nut removal to tool change, the efficiency is significantly improved compared to traditional multi-station operations. Simultaneously, the housing can accommodate operators of different heights with the help of the electric telescopic rod, reducing fatigue from bending over or raising arms, thus lowering labor intensity.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0026] refer to Figures 1-6A disassembly and assembly structure for precision machining tools in aerospace applications includes a base 1. A tool disassembly ring 101 and a shift housing 2 are sequentially arranged on the top of the base 1. Symmetrical contact elements 201 are provided on the inner side of the shift housing 2. A screw 202 and a guide rod 204 are respectively provided on both sides inside the shift housing 2. Threaded blocks 203, which are fixedly connected to one end of the contact element 201, are threaded to both ends of the screw 202. Guide blocks 205, which are fixedly connected to the other end of the contact element 201, are slidably connected to both ends of the guide rod 204. A rotating gear 5 is fixedly sleeved on the surface of the shift housing 2. A rotating gear 501 meshes with the surface of the rotating gear 5. A shaft 502 is fixedly sleeved inside the rotating gear 501. In this invention, the operator first aligns the notch at the bottom of the outer tool holder with the protrusion 103, achieving axial positioning of the tool holder through mechanical locking. Then, the electric telescopic rod 6 is activated, adjusting the contact element 201 to the same horizontal plane as the nut on the tool holder surface. The rotating motor 3 is then activated, causing the contact element 201 to engage with the nut. Then, constant force clamping is achieved through closed-loop control of the rotating motor, avoiding thread damage to the nut caused by traditional wrench disassembly and assembly, thus reducing the thread wear rate. At the same time, this setting facilitates the disassembly and assembly structure to be used with different sized handles and nuts, increasing the device's compatibility and adaptability, and making it flexible and convenient to adjust.

[0027] The tool removal ring 101 has mounting plates 102 fixedly installed on both sides and bolted to the base 1. The top of the tool removal ring 101 has symmetrical protrusions 103 fixedly installed. The bolting between the mounting plates 102 and the base 1 will facilitate the disassembly of the tool removal ring 101 under different usage conditions. The protrusions 103 fit into the notch at the bottom of the outer tool handle.

[0028] The screw 202 and the movable housing 2 are rotatably connected to each other through bearings, and the guide rod 204 is fixedly connected to the movable housing 2. The bearings enable the screw 202 to rotate smoothly inside the movable housing 2, and the fixed connection supports and fixes the guide rod 204.

[0029] A rotary motor 3 is fixedly installed inside the movable housing 2. The output end of the rotary motor 3 is fixedly connected to the shaft 301 through a coupling. The operation of the rotary motor will drive the shaft 301 to rotate.

[0030] A bevel gear 302 is fixedly sleeved at one end of shaft 301. A bevel gear 303, which is fixedly sleeved with screw 202, meshes with the surface of the bevel gear 302. The rotation of shaft 301 will drive bevel gear 302 to rotate, thereby realizing the meshing rotation of bevel gear 303.

[0031] The surface of the movable shell 2 is rotatably connected to a sleeve 4 located at the bottom of the rotating gear 5 via a bearing. A support 401 is fixedly installed on the top of the sleeve 4. The sleeve 4 will support the movable shell 2 through the bearing and cooperate with the movable shell 2 to rotate smoothly inside the sleeve 4. The support 401 will support and fix the sleeve 4.

[0032] A rotating motor 503 is fixedly installed at the bottom of the support 401. The output end of the rotating motor 503 is fixedly connected to the shaft 502 through a coupling. The operation of the rotating motor 503 will drive the shaft 502 to rotate.

[0033] An electric telescopic rod 6 is embedded in the top of the base 1. A connector 601 is fixedly installed at the output end of the electric telescopic rod 6. The connector 601 and the support 401 are fixedly connected to each other. The operation of the electric telescopic rod 6 will drive the connector 601 and the support 401 to move longitudinally.

[0034] Brief Description of Usage: In use, the operator first aligns the notch at the bottom of the outer handle with the protrusion 103, achieving axial positioning of the handle through mechanical locking. Then, the electric telescopic rod 6 is activated, causing the connecting piece 601, support piece 401, shifting shell 2, and contact piece 201 to move longitudinally. When the contact piece 201 is adjusted to be level with the nut on the handle surface, the rotating motor 3 is activated, driving the bevel gear 302 via the shaft 301, which in turn drives the bevel gear 303 and the screw 202 to rotate synchronously. The reverse threads at both ends of the screw 202 cause the two threaded blocks 203 to move towards each other at the same speed. When the contact piece 201 engages with the nut, constant force clamping is achieved through closed-loop control of the rotating motor 3, avoiding thread damage to the nut caused by traditional wrench assembly and disassembly. This design facilitates the use of different sized handles and nuts, increasing the device's compatibility and adaptability, and providing convenient and flexible adjustments. The rotating motor 503 is started, driving the rotating gear 501 via the shaft 502. After being reduced in speed by the rotating gear 5, the movable housing 2 rotates at a constant speed. The rotation direction is adjusted and matched according to the tool's disassembly or installation. When the torque and number of rotations are reached, the nut and the tool holder's threads are unscrewed. The operator then operates the electric telescopic rod 6 to move the movable housing 2 and the nut upwards, and operates the collet and tool in the nut, thus facilitating the disassembly and installation of the tool.
