Description

Technical Field

[0001] This utility model relates to the field of disassembly and assembly tooling technology, specifically a disassembly and assembly tooling for an oil distributor plate and oil pipe seat. Background Technology

[0002] The pump-motor assembly of a drive-generator, as a crucial hydraulic component within the generator, provides compensating speed to the gear train. The pump-motor is connected to the distributor plate via screws and a self-locking nut at both the pump and motor ends. The distributor plate is a disc-shaped part within the pump-motor that separates the high and low pressure oil chambers. Oil from the housing flows into the pump-motor assembly through oil pipes and a pipe seat connected to the distributor plate. The pipe seat, as the part connecting the oil pipes, is susceptible to damage from deformation, which can impede oil flow, preventing the pump-motor assembly from providing the correct compensating speed. This, in turn, affects the generator frequency and poses a serious safety hazard to the aircraft. During the disassembly and assembly of a certain type of combined drive-generator, due to the lack of suitable tooling, a flathead wrench was used to fix the oil pipe seat groove, followed by loosening the self-locking nut using an 8-gauge box wrench. However, this method resulted in the flathead wrench not fitting properly to the groove size, causing deformation and, in severe cases, irreparable damage to the groove.

[0003] To address this issue, we designed a tooling system for disassembling and assembling the oil distribution plate and oil pipe seat. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling for disassembling and assembling an oil distribution plate and oil pipe seat, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a disassembly and assembly tool for an oil distribution plate oil pipe seat, including a pipe seat body, a threaded rod threadedly connected to the pipe seat body, a connecting cylinder connected inside the threaded rod, a sliding rod slidably connected inside the connecting cylinder, a transmission rod rotatably connected to the bottom of the sliding rod, a limit block rotatably connected to the other end of the transmission rod, a slotted cutter inserted into the bottom of the threaded rod, and the limit block used to limit the slotted cutter.

[0006] Furthermore, there are two transmission rods, which are symmetrically rotatably connected to the bottom of the slide rod.

[0007] Furthermore, an installation frame is connected inside the connecting cylinder, and the limiting block is slidably connected inside the installation frame, with one end of the limiting block extending to the outside of the connecting cylinder.

[0008] Furthermore, a limiting rod is connected to the bottom of the limiting block, and the limiting rod is slidably connected within the mounting frame.

[0009] Furthermore, a knob is connected to the top of the threaded rod, one end of the slide rod extends to the outside of the knob and is connected to a force-applying plate, and a return spring is sleeved on the slide rod, one end of the return spring is connected to the force-applying plate, and the other end is connected to the knob.

[0010] Furthermore, the knob is provided with multiple anti-slip textures that are evenly distributed in a circular array.

[0011] Furthermore, two symmetrical force-applying rods are connected to the tube seat body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The vertical structure, combined with a precisely fitted single-blade cutter and pipe seat body, features a cutter blade customized to the size of the pipe seat. The inner diameter of the sleeve matches the standard self-locking nut, ensuring stable operation without shaking and effectively protecting the pipe seat groove. This greatly improves the safety of disassembly and assembly. Utilizing the linkage of the slide rod, transmission rod, and limit block, it can quickly adapt to different pipe seat models, offering strong versatility, reducing the need for tooling types and lowering costs.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figure 1-4 As shown, a tooling for disassembling and assembling an oil distribution plate oil pipe seat includes a pipe seat body 1, a threaded rod 2 threadedly connected to the pipe seat body 1, a connecting cylinder 3 connected inside the threaded rod 2, a sliding rod 4 slidably connected inside the connecting cylinder 3, a transmission rod 5 rotatably connected to the bottom of the sliding rod 4, a limit block 7 rotatably connected to the other end of the transmission rod 5, a flat cutter 10 inserted into the bottom of the threaded rod 2, and the limit block 7 is used to limit the flat cutter 10.

[0023] In practice, this disassembly and assembly fixture has a vertical structure and consists of two parts: a flathead cutter 10 of suitable size and a pipe seat body 1. The cutting edge of the flathead cutter 10 is determined based on the measured length, width, and thickness of the oil pipe seat to ensure it can perfectly fit into the groove for fixation. The inner diameter of the sleeve of the pipe seat body 1 is the size of the self-locking nut connecting the oil distributor and the oil pipe seat; since this self-locking nut is a standard part, its dimensions can be directly looked up. The two are connected by a threaded connection. The thread of the flathead cutter 10 is external at the lower end of the cutter handle, and the threaded hole of the pipe seat body 1 needs to be drilled at its upper end to generate an internal thread, allowing the two to mesh. A portion of the center of the socket wrench is cut out to allow the flathead wrench to pass through.

[0024] When using this tooling, the flathead cutter 10 secures the slot, preventing the tool from deflecting within the slot of the pipe seat body 1. The pipe seat body 1 is then fixed to the self-locking nut. Rotating the pipe seat body 1 allows the nut to be either removed from the pipe seat or tightened. This disassembly tooling offers enhanced stability, preventing any shaking that could damage the pipe seat slot. The disassembly and assembly process is efficient, safe, stable, and convenient.

[0025] Meanwhile, to facilitate the replacement of different one-piece cutting blades 10, the sliding rod 4, which has been pulled beforehand, can be released. The sliding rod 4 slides downward in the connecting cylinder 3. Since the two ends of the transmission rod 5 are rotatably connected to the bottom of the sliding rod 4 and the limiting block 7 respectively, as the sliding rod 4 moves downward, the transmission rod 5 will push the limiting block 7 to move closer to the one-piece cutting blade 10, thereby fixing the one-piece cutting blade 10. Since the slot size of different models of pipe seats may vary slightly, this setting allows for the quick replacement of different specifications of cutting blade heads, making the tooling applicable to the disassembly and assembly of pipe seats for various types of combined drive generators, thus improving the versatility of the tooling.

[0026] refer to Figure 5There are two transmission rods 5, which are symmetrically rotated and connected to the bottom of the slide rod 4.

[0027] In practice, when the slide bar 4 is pressed down, the two transmission rods 5 move synchronously and apply a pushing force to the limiting block 7 evenly, so that the limiting block 7 can move towards the cutting knife 10 smoothly and evenly, ensuring that the clamping force on the cutting knife 10 is evenly distributed on both sides.

[0028] refer to Figure 5 The connecting cylinder 3 is connected to the mounting frame 6, and the limiting block 7 is slidably connected in the mounting frame 6. One end of the limiting block 7 extends to the outside of the connecting cylinder 3.

[0029] In practice, the installation frame 6 facilitates the installation of the limit block 7.

[0030] See Figure 5 The bottom of the limiting block 7 is connected to a limiting rod, which is slidably connected within the mounting frame 6.

[0031] In practice, the limiting rod can limit and guide the sliding of the limiting block 7, further improving the stability of the limiting block 7 during the sliding process.

[0032] refer to Figure 6 A knob is connected to the top of the threaded rod 2. One end of the slide rod 4 extends to the outside of the knob and is connected to the force plate 8. A return spring 9 is sleeved on the slide rod 4. One end of the return spring 9 is connected to the force plate 8, and the other end is connected to the knob.

[0033] In practice, after disassembly, the fingers pressing the force plate 8 are released. At this time, the return spring 9, which has stored elastic potential energy due to previous compression, will release its elastic force, pushing the force plate 8 to move the slide rod 4 upward to reset. At the same time, the transmission rod 5 moves accordingly, causing the limit block 7 to return to its initial position, preparing for the next operation.

[0034] refer to Figure 6 The knob has multiple anti-slip textures 11 arranged in a circular array at equal intervals.

[0035] In practice, the anti-slip texture 11 increases friction, making it easier for users to rotate the knob.

[0036] refer to Figure 1 Two symmetrical force-applying rods 12 are connected to the tube seat body 1.

[0037] In practice, the force-applying lever 12 is designed to facilitate the application of force by the user.

[0038] Working Principle: In use, this disassembly and assembly fixture has a vertical structure and consists of two parts: a suitably sized flathead cutter 10 and a pipe seat body 1. The cutting edge of the flathead cutter 10 is determined based on the length, width, and thickness of the oil pipe seat to ensure it fits perfectly into the groove for fixation. The inner diameter of the sleeve in the pipe seat body 1 is the size of the self-locking nut connecting the oil distributor and the oil pipe seat; since this self-locking nut is a standard part, its dimensions can be directly looked up. The two parts are connected by a threaded connection. The thread of the flathead cutter 10 is external at the lower end of the cutter handle, and the threaded hole in the pipe seat body 1 needs to be drilled at its upper end to create an internal thread, allowing the two parts to mesh. A portion of the socket wrench is cut out in the center to allow the flathead wrench to pass through.

[0039] When using this tooling, the flathead cutter 10 secures the slot, preventing the tool from deflecting within the slot of the pipe seat body 1. The pipe seat body 1 is then fixed to the self-locking nut. Rotating the pipe seat body 1 allows the nut to be either removed from the pipe seat or tightened. This disassembly tooling offers enhanced stability, preventing any shaking that could damage the pipe seat slot. The disassembly and assembly process is efficient, safe, stable, and convenient.

[0040] Meanwhile, to facilitate the replacement of different one-piece cutting blades 10, the sliding rod 4, which has been pulled beforehand, can be released. The sliding rod 4 slides downward in the connecting cylinder 3. Since the two ends of the transmission rod 5 are rotatably connected to the bottom of the sliding rod 4 and the limiting block 7 respectively, as the sliding rod 4 moves downward, the transmission rod 5 will push the limiting block 7 to move closer to the one-piece cutting blade 10, thereby fixing the one-piece cutting blade 10. Since the slot size of different models of pipe seats may vary slightly, this setting allows for the quick replacement of different specifications of cutting blade heads, making the tooling applicable to the disassembly and assembly of pipe seats for various types of combined drive generators, thus improving the versatility of the tooling.
