Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) engine technology, and in particular to a fixture for processing and fixing the heat sink of a UAV engine cylinder. Background Technology

[0002] like Figure 7 As shown, the drone engine cylinder and its top heat sink are cast as a single piece. Because the top of the heat sink has an arc-shaped structure, it needs to be cut flat to create a clearance end for installing spark plugs and related accessories. Currently, the usual method is to first use bolts through the cylinder flange holes to fix the drone engine cylinder, and then use a machining tool to cut the top of the heat sink flat to create the clearance end. This method of machining the clearance end for the heat sink can only machine one drone engine cylinder at a time, and requires installing and removing bolts to fix and remove the drone engine cylinder, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] The purpose of this utility model is to provide a fixture for processing and fixing the heat sink of a drone engine cylinder, so as to achieve the purpose of processing the heat sink installation avoidance end of multiple drone engine cylinders at one time, saving time and effort, and improving processing efficiency.

[0004] The present invention provides a fixture for processing and fixing the heat sink of a drone engine cylinder, including a base, a cylinder mounting seat in the middle of the base, and spinning cylinders on both sides of the base; a cylinder is located in the middle of the cylinder mounting seat, and the cylinder mounting seat is provided with a cylinder flange positioning pin adapted to the cylinder flange hole; the spinning cylinder is connected to an external air source through an air pipe, the spinning cylinders at both ends are provided with strip-shaped pressure plates adapted to the cylinder flange, and the spinning cylinder in the middle is provided with a V-shaped pressure plate adapted to the cylinder flange, and the other end of the strip-shaped pressure plate and the V-shaped pressure plate are connected to the spinning cylinder.

[0005] Furthermore, air distribution blocks are provided on both sides of the base; one end of each air distribution block is connected to a pneumatic control switch via an air pipe; the pneumatic control switch is connected to multiple spinning cylinders via the air pipe of the air distribution block.

[0006] Furthermore, the base is provided with air distribution block fixing blocks and switch fixing plates on both sides; air distribution blocks are provided on the air distribution block fixing blocks; and pneumatic control switches are provided on the switch fixing plates.

[0007] Furthermore, both the strip-shaped pressure plate and the V-shaped pressure plate are provided with connecting holes at their other ends, and the strip-shaped pressure plate and the V-shaped pressure plate are connected to the piston rod of the spinning cylinder through the connecting holes.

[0008] The machining and fixing fixture for the coolant fins of the UAV engine cylinder provided by this utility model has the following beneficial effects:

[0009] 1. The cylinder mounting base of this utility model can fix multiple cylinders at once through the cylinder mounting base and cylinder flange positioning pin, and can process the heat sink installation clearance end of multiple cylinders each time.

[0010] 2. The spinning cylinder of this invention can drive the strip-shaped pressure plate and the V-shaped pressure plate to rotate. When the spinning cylinder is activated, the strip-shaped pressure plate and the V-shaped pressure plate are in a downward clamping state. When the spinning cylinder is closed, the strip-shaped pressure plate and the V-shaped pressure plate are in a relaxed state. The strip-shaped pressure plate and the V-shaped pressure plate facilitate the fixing and disassembly of the UAV engine cylinder, eliminating the need to install and remove bolts, saving time and effort.

[0011] Therefore, this utility model achieves one-button automatic cylinder clamping through a pneumatic control switch, and processes the heat sink installation clearance end of multiple drone engine cylinders at one time, which has the positive effects of saving time and effort and improving processing efficiency.

[0026] like Figure 1-4 As shown, the UAV engine cylinder heat sink processing and fixing fixture provided by this utility model includes a base 1, a cylinder mounting seat 2 is provided in the middle of the base 1, and spinning cylinders 3 are provided on both sides of the base 1; a cylinder 5 is provided in the middle of the cylinder mounting seat 2, and cylinder flange positioning pins 21 adapted to the cylinder flange holes 52 are provided on both sides of the cylinder mounting seat 2; the spinning cylinder 3 is connected to an external air source through an air pipe 33, and the spinning cylinders 3 at both ends are provided with strip-shaped pressure plates 31 adapted to the cylinder flanges 51, and the spinning cylinder 3 in the middle is provided with a V-shaped pressure plate 32 adapted to the cylinder flanges 51. The other ends of the strip-shaped pressure plate 31 and the V-shaped pressure plate 32 are both connected to the spinning cylinder 3.

[0027] like Figure 5-6 As shown, in use, firstly, multiple cylinders 5 are placed sequentially on the cylinder mounting base 2, with the cylinder flange holes 52 installed within the cylinder flange positioning pins 21. Then, the spinning cylinder 3 is activated, causing the strip-shaped pressure plate 31 and V-shaped pressure plate 32 to rotate 90° and press down, resulting in a clamping state where the strip-shaped pressure plate 31 and V-shaped pressure plate 32 press against the cylinder flange 51. Next, a machining tool is used to cut the tops of the heat sinks of the multiple cylinders 5 flat, forming heat sink mounting clearance ends 53. Finally, the pneumatic control switch is pressed to close the spinning cylinder 3. The spinning cylinder 3 then causes the strip-shaped pressure plate 31 and V-shaped pressure plate 32 to rise and rotate 90°, releasing them from the cylinder flange 51, allowing the multiple cylinders 5 to be removed. This method of machining the heat sink mounting clearance end 53 allows for the machining of multiple cylinder 5 heat sink mounting clearance ends 53 at a time, typically 4-8 cylinders 5 at a time. Furthermore, it eliminates the need for installing and removing bolts to fix and disassemble the UAV engine cylinders, saving time and effort and improving machining efficiency.

[0028] like Figure 1-4As shown, air distribution blocks 4 are provided on both sides of the base 1; one end of the air distribution block 4 is connected to a pneumatic control switch 41 through an air pipe 33; the pneumatic control switch 41 is connected to multiple spinning cylinders 3 through the air pipe 33 of the air distribution block. Each side of the base 1 is provided with an air distribution block 4. Pressing the pneumatic control switch 41 will simultaneously activate two air distribution blocks 4, which will then simultaneously activate five spinning cylinders 3, causing the strip pressure plate and V-shaped pressure plate to be in a downward clamping state. The strip pressure plate 31 and V-shaped pressure plate 32 press down on the flanges 51 of four cylinders, which can process the heat sink installation clearance end 53 of four cylinders 5 at one time, improving processing efficiency.

[0029] like Figure 1-4 As shown, the base 1 is also provided with a gas distribution block fixing block 11 and a switch fixing plate 12 on both sides; a gas distribution block 4 is provided on the gas distribution block fixing block 11; and a pneumatic control switch 41 is provided on the switch fixing plate 12. The gas distribution block fixing block 11 facilitates the installation of the gas distribution block 4, and the switch fixing plate 12 facilitates the installation of the pneumatic control switch 41, thereby improving practicality and convenience.

[0030] like Figure 5-6 As shown, both the strip-shaped pressure plate 31 and the V-shaped pressure plate 32 have connecting holes at their other ends. The strip-shaped pressure plate 31 and the V-shaped pressure plate 32 are connected to the piston rod of the spinning cylinder 3 via screws passing through the connecting holes. When the spinning cylinder 3 is activated, the strip-shaped pressure plate and the V-shaped pressure plate are clamped. When the spinning cylinder 3 is closed, the strip-shaped pressure plate and the V-shaped pressure plate are released. The strip-shaped pressure plate 31 and the V-shaped pressure plate 32 facilitate the fixing and disassembly of the UAV engine cylinder, eliminating the need to install and remove bolts, saving time and effort, and improving processing efficiency.

[0031] 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.
