Description

Technical Field

[0001] This invention relates to a rapid leveling and vibration damping device for multi-angle plate-like parts and its usage method. Specifically, it involves using the rapid leveling and vibration damping device for multi-angle plate-like parts to achieve rapid angle leveling and vibration damping during the machining process, and then performing machining on a three-axis machine tool. It belongs to the field of machining. Background Technology

[0002] Multi-angle plate parts refer to plate-shaped parts with two or more angles on their surface. These plate parts have wide applications in the aerospace and aviation fields.

[0003] Currently, the machining of such parts is usually carried out by designing angle fixtures and using three-axis machine tools. However, each angle requires a separate fixture design, resulting in a large number of angle fixtures used when machining the part, leading to low machining efficiency and high cost. Alternatively, five-axis machine tools can be used to machine the part from multiple angles, but the hourly rate of a five-axis machine tool is about twice that of a three-axis machine tool, resulting in higher machining costs.

[0004] Meanwhile, the vibration damping method used in the processing of such parts typically employs auxiliary supports with universal joints, which are manually tightened one by one using a dial indicator. This method generally has a low vibration damping effect and low operational efficiency. Alternatively, a method of large-angle conformal surface contact and clamping can be used for vibration damping, which has a better vibration damping effect but higher manufacturing cost.

[0005] Therefore, in order to reduce production costs and improve production efficiency, it is necessary to design a reasonable processing device and innovate a method for rapid leveling of multi-angle plate parts and vibration reduction during processing, so as to achieve low-cost and high-efficiency machining of such parts. Summary of the Invention

[0006] The present invention aims to provide a device for rapid leveling and vibration reduction in the processing of multi-angle plate parts.

The thumb-type clamping cylinder is a standard part, installed and fixed to the support base using 4-M6 hex socket screws. The rubber pad is attached to the two thumbs on the thumb-type clamping cylinder using 502 adhesive.

[0093] A method for using a rapid leveling and vibration damping device for multi-angle plate parts includes:

[0094] 1) Fixed base: Use a dial indicator to straighten and align the sides of the base, and then clamp and fix the base to the machine tool worktable with 4-M20 hex socket screws;

[0095] 2) Install the angle adjustment mechanism positioning components: Based on the distance between the centers of the process chuck containing the part positioning holes (325×80), use 2-ø10 cylindrical pins and 2-ø10 diamond pins to position the two angle adjustment mechanism positioning components respectively, and then install and fix them to the base with 4-M10 hex socket screws. See [link / reference]. Figure 3 , 15 ;

[0096] 3) Install the angle adjustment mechanism assembly: Based on the center position distance of the process chuck (excluding the part positioning holes) of 325×380, use ø10 cylindrical pins and ø10 diamond pins for positioning, and install the angle adjustment mechanism assembly using 2-M10 hex socket screws. Clamp and fix it to the base. Two installation points are required. See [link / reference]. Figure 8 , 15 ;

[0097] 4) Machining the angle surface and product machining height reference surface and installing limit pins: Move the rotary clamping cylinder pressure plate to one side to avoid interference during machining. Use the machine tool to machine the angle adjustment mechanism positioning component, the angle surface of the angle adjustment mechanism component, and the product machining height reference surface. The angle is 2.76°. Based on the position distance of the part positioning hole on the part's process chuck, machine the limit pin mounting hole ø6+0.005 -0.01, with a distance of 325×80. After machining, install the limit pins (one cylindrical pin and one diamond pin).

[0098] 5) Install the part: Align the pin hole on the part's process chuck with the upper limit pin of the angle adjustment mechanism's positioning component. Gently press the part to ensure a good fit between the pin hole and the limit pin on the process chuck, and that the process chuck surface is tightly fitted with the angle block surface on the angle adjustment mechanism's positioning component and angle adjustment mechanism component. (See [link]) Figure 15 ;

[0099] 6) Install the thumb-type clamping cylinder assembly: Select appropriate rubber pads according to the angle surface of the part to be machined, and glue the rubber pads to the two thumbs on the thumb-type clamping cylinder. Adjust the position of the two thumbs on the thumb-type clamping cylinder to be the same distance from the sides of the part's ribs, and install the thumb-type clamping cylinder using 2-M10 hex socket screws. Secure it to the base (see [reference]). Figure 15 ;

[0100] 7) Install the integrated support and suction cylinder assembly: Based on the non-ribbed position of the part, adjust the position of the support cylinder and the suction nozzle, and install and fix the thumb-type clamping cylinder assembly on the base using 2-M10 hex screws; adjust the height of the suction nozzle using the threaded rod to ensure it is flush with the surface to be suctioned, and adjust the height of the universal joint threaded rod to ensure the universal joint is at a suitable distance from the surface to be supported.

[0101] 8) Connect the rotary clamping cylinder, thumb clamping cylinder, support bar, and suction nozzle using an air hose, and use the switch to make the rotary clamping cylinder clamp the part's process chuck, the thumb clamping cylinder clamp the part's ribs, the support cylinder support and press against the part's surface, and the suction nozzle tightly suction the part's surface.

[0102] When it is necessary to process another angle surface B of the part or to replace the part, loosen the rotary clamping cylinder, remove the part, and repeat the above operation process according to the surface angle of the part to be processed, the distance of the center position of the process chuck, and the size and distance of the part positioning hole.

[0103] The main features, specific implementations, and advantages of the present invention have been detailed above. It should be noted that those skilled in the art can make various improvements and variations based on the technical principles of this invention, but these improvements and variations should also be considered within the scope of protection of this invention.
