Description

Technical Field

[0001] This invention belongs to the field of aerospace manufacturing technology and relates to a flexible bracket welding and positioning device. Background Technology

[0002] Aviation welded brackets are characterized by their variety and small batch production. Each type of welded bracket requires a dedicated positioning welding fixture for welding. Due to the complexity of the bracket types and the high number of specialized tooling, warehouse management pressure has increased, and space shortages have become increasingly serious. Furthermore, the slight differences between some brackets can easily lead to the mixing of tooling during actual operation, resulting in parts requiring rework and scrapping, thus affecting the final delivery of parts. Summary of the Invention

[0003] Purpose of the invention

[0004] This invention overcomes the shortcomings of the prior art and provides a flexible bracket welding positioning device, which solves the problems of positioning and welding of welding bracket parts, increases the manufacturing quality of parts, and reduces the pressure of warehouse management.

[0005] Technical solution

[0006] A flexible support welding and positioning device includes a base, a rotating frame, and support arms. The center of the base plate 1 and the support positions on both sides are hollowed out. Supports 2 have through holes drilled in their bottoms and arc-shaped grooves at their tops. Two supports 2 are inserted into the hollowed-out positions on both sides of the base plate 1 and fixed by end-face pins. The rotating frame is a plate-like structure with a central slot 5. Threaded shafts A4 are symmetrically and coaxially welded to the upper ends on both sides, and pins 3 are symmetrically and coaxially welded to the lower ends on both sides. The symmetrical threaded shafts A4 pass through the arc-shaped grooves on the supports 2, and the symmetrical pins 3 pass through the through holes at the bottom of the supports 2, allowing the rotating frame to rotate within the arc-shaped grooves with the pins 3 as fulcrums. The rotation position is fixed by nuts. One side of the support arm is connected to the slot 5 via a welded threaded shaft B6 and fixed by nuts. The other side of the support arm has a mounting hole 7 for positioning with assembly holes on parts.

[0007] Furthermore, the rotation angle of the rotating frame should meet the deflection angle requirements of the lugs on the part.

[0008] Furthermore, the thickness of the hollowed-out area at the center of the base plate 1 is consistent with the thickness of the part.

[0009] Furthermore, the length of the hollowed-out area at the center of the base plate 1 is greater than the length of the part.

[0010] Furthermore, the width of the hollowed-out area at the center of the base plate 1 is greater than the width of the part.

[0011] Furthermore, the base plate 1 is integrally formed by machining from structural steel material.

[0012] Furthermore, the support 2 is made of structural steel.

[0013] Furthermore, the rotating frame and support arm are both made of structural steel.

[0014] The beneficial effects of this application are as follows:

[0015] This invention provides a flexible bracket welding positioning device, which combines the positions of the rotating frame and the support arm to form any required bracket angle, thereby achieving the purpose of positioning and welding, reducing the cost of special tooling and the pressure of warehouse management.

[0021] The present invention will be further described below with reference to embodiments. The following description represents only a portion of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] like Figure 1 As shown, a flexible support welding and positioning device is provided. The device is composed of a base, a rotating frame, and a support arm. The base and the rotating frame are connected by a pin and a hole, and the rotating frame and the support arm are connected by quick-release bolts.

[0023] like Figure 2 As shown, the base consists of a base plate 1 and supports 2. The center of the base plate 1 and the support positions on both sides are hollowed out. The bottom of the support 2 is drilled with a through hole, and the top is an arc-shaped groove. The two supports 2 are inserted into the hollowed-out positions on both sides of the base plate 1 and fixed by end face pins, allowing for quick assembly and disassembly.

[0024] like Figure 3 As shown, the center of the rotating frame is a slot 5, and pins 3 and threaded shafts A4 are welded to the top and bottom of both sides respectively, and the two shafts are ensured to be coaxial.

[0025] like Figure 4As shown, a threaded shaft B6 is welded to one side of the support arm, and a mounting hole 7 is on the other side, which can be used to fix it in place with the mounting hole of the bracket.

[0026] The support arm is connected to the slot 5 of the rotating frame via a threaded shaft B6 and can be fixed by a quick-release nut. The support arm can move up and down in the slot 5. Furthermore, the pin 3 in the rotating frame is installed into the corresponding through hole of the base, and the threaded shaft A4 is installed into the corresponding arc groove of the base and can be fixed by a quick-release nut. The whole can rotate at a fixed angle along the arc groove with the pin 3 as the center. Furthermore, the support 2 can be inserted into the corresponding groove of the base plate 1 and fixed by a pin.

[0027] During operation, firstly, the corresponding positions of each moving part are determined by the actual sample of the part to be welded, and each moving part is fixed by bolts; then, the pin of the fixed support 2 on the base is removed, the upper clamping body is removed, and the actual sample is taken out (if the actual sample can be removed smoothly, the device does not need to be disassembled); then, the device is used to assemble and repair the bracket parts, and the positioning welding work is completed.
