Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) engine exhaust pipe technology, and in particular to a UAV engine exhaust pipe base riser press fitting tool. Background Technology

[0002] When a drone engine is in flight, the exhaust gases it produces are discharged through the exhaust pipe. For example... Figure 6 As shown, the exhaust pipe of a drone engine consists of a base and a riser. Currently, when processing the exhaust pipe, the riser needs to be manually hammered into the base first. Only after the riser's verticality is checked and found to be acceptable can subsequent welding work proceed. However, manually hammering the riser can easily cause it to tilt. Furthermore, when checking the verticality, it is impossible to visually distinguish which riser is tilted, requiring both risers to be removed and reprocessed, increasing the workload. Utility Model Content

[0003] The purpose of this utility model is to provide a tooling for pressing and fitting the riser of the exhaust pipe base of a drone engine, so as to avoid tilting of the riser of the drone engine exhaust pipe and improve the processing efficiency of the drone engine exhaust pipe.

[0004] The UAV engine exhaust pipe base riser press fitting provided by this utility model includes a base plate, with a middle plate connected to both ends of the base plate by guide posts, and a support block provided at the bottom of the base plate; the middle plate is connected to an upper plate and a top plate by limiting bolts, and a riser fixing cylinder is vertically provided on the middle plate, with a middle plate drop hole in the middle of the middle plate that matches the riser drop hole of the riser fixing cylinder; a punch adapted to the edge of the riser is provided at the bottom of the upper plate, and a top plate is provided at the upper end of the upper plate; a press adapter is provided at the upper end of the top plate; and the guide posts penetrate the base plate.

[0005] Furthermore, the two ends of the riser fixing cylinder are provided with riser partitions through slots, a row of risers is vertically arranged inside the riser fixing cylinder, and a square flat spring is provided at the rear end of the riser fixing cylinder.

[0006] Furthermore, the front end of the riser fixing cylinder is provided with a riser drop hole adapted to the riser, and the riser drop hole is located at the front end of the riser partition.

[0007] Furthermore, the riser fixing cylinder is connected to the middle plate via fixing cylinder bolts at its front end.

[0008] Furthermore, the bottom plate is provided with limiting blocks at both ends that are adapted to the base of the exhaust pipe, and a positioning pin is provided in the middle of the bottom plate that is adapted to the mounting hole of the base of the exhaust pipe, and the positioning pin is located between the two limiting blocks.

[0009] Furthermore, a spring is provided at the bottom of the middle plate, and the spring is located inside the guide post.

[0010] Furthermore, the bottom plate is provided with limit bolt clearance holes at both ends, and the limit bolt clearance holes are located on the outside of the guide post.

[0011] The UAV engine exhaust pipe base riser press-fit tooling provided by this utility model has the following beneficial effects:

[0012] 1. The press adapter of this utility model can be connected to a press to provide impact force for the processing and installation of risers.

[0013] 2. The base of the exhaust pipe of this utility model is placed on the middle plate, the riser is placed in the riser fixing cylinder, and the press drives the punch to press on the riser, so that the riser is vertically installed on the base from the riser in the riser fixing cylinder, ensuring that the riser of the drone engine exhaust pipe is vertical.

[0014] 3. After the press of this utility model is raised, the base can be rotated to vertically install another riser on the base. In this way, both risers on the exhaust pipe base are vertical, eliminating the need to re-process and install the risers, thus reducing workload.

[0015] Therefore, this invention eliminates the need for manual hammering of the riser into the base when processing the exhaust pipe of a drone engine, ensuring the riser's verticality. Simultaneously, it avoids reprocessing the riser, reducing workload and effectively preventing tilting of the drone engine exhaust pipe riser, thus improving processing efficiency.

[0030] like Figure 1-2 As shown, the UAV engine exhaust pipe base riser press fitting tool provided by this utility model includes a base plate 1, with guide posts 22 connecting the two ends of the base plate 1 to a middle plate 2, and a support block 12 provided at the bottom of the base plate 1; the middle plate 2 is connected to an upper plate 4 and a top plate 5 by limiting bolts 21, a riser fixing cylinder 3 is vertically provided on the middle plate 2, and a middle plate drop hole adapted to the riser drop hole of the riser fixing cylinder 3 is provided in the middle of the middle plate 2; a punch 41 adapted to the edge of the riser 61 is provided at the bottom of the upper plate 4, and a top plate 5 is provided at the upper end of the upper plate 4; a press adapter 51 is provided at the upper end of the top plate 5; and the guide posts 22 penetrate the base plate 1.

[0031] like Figure 3-5 As shown, in use, the top plate 5 is first connected to the press via the press adapter 51. Then, the base 62 of the exhaust pipe 6 is placed on the middle plate 2, with the riser mounting hole of the base 62 corresponding to the middle plate drop hole of the middle plate 2. The riser 61 is then placed inside the riser fixing cylinder 3. Next, the press is started, and the press drives the punch 41 to press against the edge of the riser 61, so that the riser 61 passes through the riser drop hole of the riser fixing cylinder 3 and the middle plate drop hole of the middle plate 2 in sequence, and is then pressed into the riser mounting hole of the base 62, thus vertically installing the riser 61 on the base 62. Then, the press is raised upwards, and the press drives the punch 41 to detach from the riser fixing cylinder 3. The press continues to rise upwards, and the press drives the middle plate 2, the upper plate 4, and the top plate 5 to move upwards, and the guide post 22 detaches from the bottom plate 1 until the riser 61 is located below the middle plate 2. Finally, rotate the base 62 so that the other riser mounting hole of the base 62 corresponds to the middle plate drop hole of the middle plate 2. Following the above operation, start the press and vertically install the other riser 61 on the base 62.

[0032] like Figure 1-3As shown, riser fixing cylinder 3 has riser partitions 31 at both ends via slots, and a row of risers 61 is vertically arranged inside riser fixing cylinder 3. A square flat spring 32 is provided at the rear end of riser fixing cylinder 3. Multiple risers 61 can be placed side by side inside riser fixing cylinder 3, and the riser partitions 31 and square flat springs 32 at both ends fix them. The square flat springs 32 push the riser partitions 31 forward in the moving slot, driving the risers 61 forward and falling into the riser drop holes of riser fixing cylinder 3. After all the risers 61 in the row inside riser fixing cylinder 3 have fallen, the riser partitions 31 are pulled to install a new row of risers 61. This process is repeated to vertically install multiple risers 61 onto base 62, improving the processing efficiency of UAV engine exhaust pipes.

[0033] like Figure 3 As shown, the front end of the riser fixing cylinder 3 is provided with a riser drop hole that matches the riser 61, and the riser drop hole is located at the front end of the riser partition 31. The riser drop hole matches the riser 61, which can ensure that the riser 61 can fall smoothly from the riser drop hole into the middle plate drop hole of the middle plate 2 and be pressed into the riser mounting hole of the base 62, and can also prevent the riser 61 from tilting during the fall, so that the riser 61 is vertically installed on the base 62.

[0034] like Figure 3 As shown, the riser fixing cylinder 3 is connected to the middle plate 2 via the fixing cylinder bolt 33 at its front end. The riser fixing cylinder 3 is located in the middle of the middle plate 2, and the fixing cylinder bolt 33 can prevent the riser fixing cylinder 3 from shifting, thus preventing the riser 61 of the UAV engine exhaust pipe from tilting.

[0035] like Figure 1 , 3 As shown in Figure 4, the base plate 1 has limiting blocks 11 at both ends that are adapted to the base 62 of the exhaust pipe 6, and a positioning pin 13 in the middle of the base plate 1 that is adapted to the mounting hole of the base 62 of the exhaust pipe 6, with the positioning pin 13 located between the two limiting blocks 11. When the mounting hole of the base 62 of the exhaust pipe 6 is installed in the positioning pin 13, the limiting blocks 11 prevent the base 62 from shifting, allowing the vertical pipes 61 to be installed vertically on the base 62 in sequence, thus improving the processing efficiency of the UAV engine exhaust pipe.

[0036] like Figure 1 , 3 As shown, a spring 23 is also provided at the bottom of the middle plate 2, and the spring 23 is located inside the guide post 22. After the riser 61 is processed, the middle plate 2 can be pressed down by the spring 23, the riser fixing cylinder 3 can be removed, and multiple risers 61 can be placed side by side in the riser fixing cylinder 3 to improve the processing efficiency of the UAV engine exhaust pipe.

[0037] like Figure 1As shown, the base plate 1 has limit bolt clearance holes 14 at both ends, and the limit bolt clearance holes 14 are located on the outside of the guide post 22. The limit bolt clearance holes 14 facilitate the installation of limit bolts 21. The limit bolts 21 connect the middle plate 2, the upper plate 4 and the top plate 5 together, and multiple risers 61 can be vertically installed on the base 62 in sequence, improving the processing efficiency of the UAV engine exhaust pipe.

[0038] The installation, connection, or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structure, model, and coefficient indicators of all components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented.
