Description

Technical Field

[0001] The present invention relates to the technical field of accessory welding, and particularly relates to a stamping and welding device for accessories used in aircraft production. Background Art

[0002] A small manned aircraft, also known as an ultra-light aircraft, generally refers to a small general-purpose aircraft driven by a propeller, with no more than 2 crew members and a maximum takeoff mass of no more than 480 kg. Figure 19 The figure shows a schematic diagram of the accessory structure on a small manned aircraft, including a sleeve 800, a connecting plate 801, and a connecting sleeve 802. When producing this aircraft accessory, welding production is required.

[0003] Chinese Patent Application No. 202322818811X discloses a welding device for automotive accessories, which relates to the technical field of welding devices. It includes a base table, a telescopic rod, and a welding device. This automotive accessory welding device is provided with multiple adjustment devices. Place the workpiece on the second workbench, rotate the adjustment rod to drive the connecting block and the clamping block to clamp the workpiece, and then start the second motor to drive the ball screw to rotate. The movement state of the second motor is intermittent forward rotation and then intermittent reverse rotation, realizing the left and right reciprocating movement of the screw nut. Under the action of the limiting rod, the screw nut drives the first workbench to move left and right.

[0004] When producing aircraft accessories, it is necessary to first stamp the connecting plate 801, then install the connecting sleeve 802 into the installation hole of the connecting plate 801, and then weld the connecting sleeve 802 and the connecting plate 801. Obviously, the above welding device is not convenient for Figure 19 producing and welding the aircraft accessories shown in the figure. Therefore, we propose a stamping and welding device for accessories used in aircraft production. Summary of the Invention

[0019] (1) In the present invention, the upper die is driven by the linear driving member e to stamp the sheet metal part in a horizontal state, and mounting holes are punched in the connecting plate. By driving the swing arm a to swing upward and driving the swing arm b to rotate downward to an inclined state, at this time, the welding nozzle contacts the welding area of the connecting sleeve and the sheet metal part, and the welding nozzle is driven to rotate along the axis of the connecting sleeve, and the welding nozzle performs circular welding production on the welding area of the connecting sleeve and the sheet metal part.

[0020] (2) In the present invention, the rotary driving member a drives the flipping plate a to flip, the linear driving member a drives the supporting wheel to move upward, so as to drive the supporting wheel to support the sheet metal part sleeved on the positioning rod, the rotary driving member b drives the flipping plate b to flip, and the linear driving member b drives the oiling wheel to apply oil to the surface of the sheet metal part.

[0022] (4) In the present invention, when the sheet metal part is at the loading station, the oiling station, the stamping station, and the welding station, the ventilation pipe is in communication with the negative pressure groove. That is to say, the negative pressure is transmitted through the ventilation pipe and the pressure chamber to the adsorption hole to adsorb and fix the sheet metal part on the positioning rod to prevent the sheet metal part from detaching. When the sheet metal part is transported to the unloading station, the positive pressure hole is in communication with the ventilation pipe, and the positive pressure is transmitted through the ventilation pipe and the pressure chamber to the adsorption hole to blow down the sheet metal part until the sheet metal part falls into the collection box, completing the unloading of the sheet metal part.

[0023] (5) In the present invention, the coating assembly, the welding assembly, the support block, and the swing rod extend upward along the mounting hole and the connecting sleeve, and then change their shapes for coating and welding.

[0080] Step 3, stamping process: the rotary drive c102 drives the rotating disk 103 to rotate, and transfers the sheet metal part sleeved on the positioning rod 105 to the stamping station. At this time, the sheet metal part is tilted and placed on the lower mold 312. The linear drive c108 drives the conical pressure plate 110 to move downward and press on the fixing seat 104. The elastic connecting member 107 is compressed. At this time, the sheet metal part is in a horizontal state on the lower mold 312. The linear drive e313 drives the upper mold 314 to stamp the horizontal sheet metal part, and punches out the installation hole in the connecting plate 801.

[0081] Step 4, Grinding process: The rotary driving part c102 drives the rotary disk 103 to rotate, transports the sheet metal part sleeved on the positioning rod 105 to the welding station, drives the lifting seat 431 to move upward until the sheet metal part is horizontally above the lifting seat 431, the rotary driving part d415 drives the rotary frame 416 to rotate, drives the grinding assembly 42 to rotate downward, the rotary driving part e421 drives the flexible grinding block 422 to rotate, and the rotating flexible grinding block 422 grinds the mounting hole of the sheet metal part to increase the roughness of the welding area;

[0082] Step 5, Assembly process: The conveyor belt b411 transports the connecting sleeve 802, the rotary driving part d415 drives the rotary frame 416 to rotate, drives the adsorption sleeve 418 to rotate downward, and drives the adsorption sleeve 418 to carry and press the connecting sleeve 802 on the conveyor belt b411 into the mounting hole of the sheet metal part for subsequent welding;

[0083] Step 6, Coating process: The linear driving part d432 drives the coating assembly 43, the welding assembly 44, the support block 435, and the swing rod 436 to extend upward along the mounting hole and the connecting sleeve 802, drives the swing rod 436 to rotate to the horizontal state, drives the swing arm b441 to swing upward, drives the swing arm a437 to rotate downward to the inclined state, and at this time the coating block 438 contacts the connecting sleeve 802 and the welding area of the sheet metal part;

[0084] The rotary driving part f433 drives the coating block 438 to rotate along the axis of the connecting sleeve 802, and the coating block 438 annularly coats the antireflection agent on the welding areas of the connecting sleeve 802 and the sheet metal part, and increasing the roughness of the welding area is beneficial to the absorption of the antireflection agent.

[0085] Step 7, Welding process: Drive the swing arm a437 to swing upward, drive the swing arm b441 to rotate downward to the inclined state, and at this time the welding nozzle 442 contacts the welding areas of the connecting sleeve 802 and the sheet metal part (as shown in Figure 18 the D state in), drive the welding nozzle 442 to rotate along the axis of the connecting sleeve 802, and the welding nozzle 442 performs annular welding on the welding areas of the connecting sleeve 802 and the sheet metal part, and the antireflection agent enhances the welding effect.

[0086] Step Eight, Adsorption and Unloading Process: The rotary drive c102 drives the rotary disk 103 to rotate, and transports the sheet metal parts sleeved on the positioning rod 105 to different workstations. When it is at the loading station, oiling station, stamping station, and welding station, the ventilation pipe 115 is connected to the negative pressure groove 1121. That is to say, the negative pressure is transmitted through the ventilation pipe 115 and the pressure chamber 1041 to the adsorption holes 1051 to adsorb and fix the sheet metal parts on the positioning rod 105 to prevent the sheet metal parts from detaching. When the sheet metal parts are transported to the unloading station, the positive pressure holes 1122 are connected to the ventilation pipe 115, and the positive pressure is transmitted through the ventilation pipe 115 and the pressure chamber 1041 to the adsorption holes 1051 to blow down the sheet metal parts until the sheet metal parts fall into the collection box, completing the unloading of the sheet metal parts.

[0087] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
