Description

Technical Field

[0001] The invention belongs to the technical field of aviation parts production, and in particular relates to a welding system and a welding method for an aviation display frame. Background Art

[0002] The welding system plays a key role in the assembly of the aviation display frame, including: 1) The welding system can accurately locate the various components of the display frame to ensure that the relative positions of the components are accurate during the welding process. This is crucial to ensure the overall performance and reliability of the aviation display, as any slight position deviation may affect its display effect and durability. 2) By using the welding system, fast and stable welding of the display frame can be achieved. The design of the tooling usually takes into account the convenience and efficiency of the welding operation, allowing workers to complete the welding work more easily and quickly. This helps to shorten the assembly cycle and improve production efficiency. 3) The welding system not only helps to maintain the precise position of the components, but also provides the necessary support and clamping to prevent deformation or displacement during the welding process. This helps to ensure the quality of the welded joint and improve the overall strength and stability of the aviation display frame. 4) The aviation display frame may be composed of components of different sizes and materials. The design of the welding system usually has a certain degree of flexibility and adjustability to adapt to the welding needs of different components. This helps to reduce production costs and improve the utilization of tooling.

[0003] The traditional welding system for aviation display frames has been found to have shortcomings during the assembly and production of aviation display frames: first, it cannot realize the pre-assembly of the aviation display frame body and the radiator bracket, nor can it realize the automatic welding of the aviation display frame with the radiator bracket and the radiator shell. The degree of automation is low, which is not conducive to the industrial assembly of large-scale aviation display frames; second, it cannot preheat the welding parts before welding, resulting in stress deformation of the welding parts due to uneven heating, and the welding effect is not ideal.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] like Figure 1 , Figure 5 and Fig.13 As shown, this embodiment provides a welding system for an aviation display frame, the welding system includes a suspension conveying assembly, a first manipulator, a pressure-bearing assembly 3, a bending assembly 4, a second manipulator, a third manipulator, a preheating assembly 5 and a welding assembly 6; the welding system is sequentially provided with a first station for receiving an aviation display frame body 7, a second station for installing a radiator support frame 8 on the received aviation display frame body 7 and a third station for performing welding operations along the conveying direction of the suspension conveying assembly.

[0059] The suspension conveying assembly includes a circular guide rail circulation line 1, a lifting push rod and a clamping hanger 2.

[0063] In this embodiment, the first manipulator, the second manipulator and the third manipulator are existing conventional structures and are not shown in the drawings to simplify the drawings.

[0064] like Figure 2-Figure 3 As shown, the aviation display frame is composed of an aviation display frame body 7, a radiator support 8, and a radiator shell 9. The aviation display frame body 7 can provide support for the radiator shell 9 from the inside by adding radiator supports 8 at both ends, thereby ensuring the overall structural stability after subsequent welding and fixing. The radiator shells 9 on both sides are pre-installed with induced fans and exhaust fans before welding, respectively. The induced fans and exhaust fans can be used to achieve rapid heat dissipation of the inner cavity of the aviation display frame body 7, so that the electrical components such as the display screen installed therein can work stably and avoid internal overheating problems.

[0065] In this embodiment, the aviation display frame body 7 includes a frame 701, which is a rectangular tubular structure. The upper plate of the frame 701 is provided with a display screen mounting hole 702, and the upper plate of the frame 701 is provided with a button exposure hole 703 at the periphery of the display screen mounting hole 702. The lower plate of the frame 701 is provided with a matching through hole below the display screen mounting hole 702, and broken grooves are provided on both sides of the matching through hole. The lower plate of the frame 701 is provided with a button mounting hole 704 below the button exposure hole 703. The middle of the two side plates of the frame 701 are evenly distributed with heat dissipation holes 705, and the two side plates of the frame 701 are provided with bayonet 706 at both ends for facilitating the installation of the radiator support frame 8.

[0066] like Figure 4 As shown, the radiator support frame material part 8a includes a rectangular frame part 801, the specifications of the rectangular frame part 801 are matched with the side panel specifications of the aviation display frame body 7, and the two ends of the rectangular frame part 801 are respectively connected to the support part 803 through the connecting plate part 802, and the connecting plate part 802 in the radiator support frame material part 8a is a straight plate structure; the radiator support frame 8 is formed by bending the connecting plate part 802 in the radiator support frame material part 8a by 90 degrees, and after bending, the support part 803 is located near the edge of the rectangular frame part 801 and can just be abutted against the outer wall of the side panel of the aviation display frame body 7, and each of the support parts 803 is formed with two right-angle positioning parts for facilitating the clamping and installation of the radiator shell 9. The radiator support frame 8 is provided with four right-angle positioning parts, and the four right-angle positioning parts form a rectangular clamping area.

[0067] In this embodiment, the radiator housing 9 includes an open shell 901, the cross-sectional specifications of the open shell 901 match the cross-sectional specifications of the aviation display frame body 7, and one end of the open shell 901 is provided with a rectangular opening 902 that matches the radiator support frame 8, and the rectangular opening 902 is specifically engaged with a rectangular clamping area surrounded by four right-angle positioning parts. The open shell 901 is provided with a plurality of fan installation areas 903 for convenient installation of exhaust fans or induced fans.

[0068] In this embodiment, the two long side seams where the inner cavity of the rectangular frame portion 801 of the radiator support 8 is attached to the inner wall of the side panel of the aviation display frame body 7 serve as two inner welding lines, and the two long side seams where the opening shell 901 of the radiator shell 9 abuts against the aviation display frame body 7 serve as two outer welding lines.

[0069] like Figure 6-Figure 7 As shown, the clamping hanger 2 includes a C-shaped clamping frame 201, and a screw motor 202 is symmetrically installed on the outer side of the upper plate of the clamping frame 201. The output end of the screw motor 202 is installed with a vertical screw 203 that matches the position of the interrupted groove in the aviation display frame body 7, and a movable horizontal pressure plate 204 is installed on the outer side of the vertical screw 203. The lower side of the movable horizontal pressure plate 204 is provided with a positioning block 205 that matches the button exposure hole 703, and the upper side of the lower plate of the clamping frame 201 is provided with a positioning protrusion 206 that matches the button installation hole 704; the inner side of the side plate of the clamping frame 201 is provided with a vertical guide rail, and the movable horizontal pressure plate 204 is provided with a guide groove that matches the vertical guide rail.

[0070] The working principle of the clamping hanger 2 is as follows: when the aviation display frame body 7 is conveyed by the first manipulator into the interior of the clamping frame 201, the clamping frame 201 first moves up a distance, so that the positioning protrusion 206 on the upper side of the lower plate is inserted into the button mounting hole 704 of the aviation display frame body 7, and then the screw motor 202 is started, and the vertical screw 203 is used to drive the movable horizontal pressure plate 204 to move downward, so that the positioning block 205 is inserted into the button exposure hole 703 of the aviation display frame body 7. At this time, the clamping and locking of the aviation display frame body 7 by the clamping hanger 2 is completed.

[0071] like Figure 8 As shown, the pressure-bearing component 3 includes a pressure-bearing base plate 301, a longitudinal hydraulic push rod 302 and a pressure block 303. Two longitudinal hydraulic push rods 302 are installed side by side on the pressure-bearing base plate 301. The movable end of the longitudinal hydraulic push rod 302 is installed with a pressure block 303 for pressing against the outer wall of the end of the side panel of the aviation display frame body 7.

[0072] The working principle of the pressure-bearing component 3 is as follows: when the side panels in the aviation display frame body 7 need to bear pressure, the longitudinal hydraulic push rod 302 is actuated to drive the pressure-bearing block 303 to press against the outer wall of the end of the side panel in the aviation display frame body 7. In this way, when the bending component 4 bends the radiator support raw material 8a, the pressure-bearing component 3 provides pressure to the side panels in the aviation display frame body 7 to prevent them from deformation.

[0073] like Figure 9-10 As shown, the bending assembly 4 includes a transverse slide rail, a transverse slider, a support seat 402, a mounting vertical plate 403, a clamping block 404, an ear seat 405, a gear roller 406, a pressing plate 407, a pressure head 408, a transverse hydraulic push rod 409 and a movable rack 410. The transverse slide rail is provided with a transverse slider which forms a linear guide rail pair 401 with the transverse slide rail, and the transverse slide rail is provided with a mounting vertical plate 403 through the support seat 402. A clamping block 404 for facilitating the installation of the radiator support frame raw material 8a is symmetrically provided on one side of the mounting vertical plate 403, and a group of ear seats 405 and a group of transverse hydraulic push rods 409 are symmetrically installed on the other side of the mounting vertical plate 403. A gear roller 406 is movably supported in the ear seat 405, and the two ends of the gear roller 406 are connected to a pressure head 408 which cooperates with the support frame part 803 in the radiator support frame raw material 8a through the pressing plate 407, and a movable rack 410 meshing with the gear roller 406 is installed at the output end of the transverse hydraulic push rod 409. The transverse hydraulic push rod 409, the movable rack 410 and the gear roller 406 together constitute a turning drive mechanism. The height value of the entirety of the bending assembly 4 except the linear guide rail pair 401 is not greater than the thickness value of the inner cavity of the aviation display frame body 7.

[0074] The working principle of the bending component 4 is as follows: when the radiator support frame raw material 8a is transferred to the bending component 4 by the second manipulator, the rectangular frame portion 801 of the radiator support frame raw material 8a is clamped on the outer side of the two clamping blocks 404, and then the linear guide pair 401 is started, and the vertical plate 403 and its upper components are installed to enter the inner cavity of the aviation display frame body 7 until the rectangular frame portion 801 of the radiator support frame raw material 8a is completely attached to the inner wall of the side plate of the aviation display frame body 7, and then the two horizontal hydraulic push rods 409 are started, and the movable rack 410 slides along its length direction and drives the gear roller 406 to flip. The gear roller 406 drives the pressure head 408 to flip accordingly through the pressure plate 407. During the flipping process, the pressure head 408 can push the support portion 803 and the connecting plate portion 802 of the radiator support frame raw material 8a to flip toward the clamping port 706, and finally the connecting plate portion 802 in the radiator support frame raw material 8a is bent 90 degrees to form the radiator support 8.

[0076] In this embodiment, the welding drive assembly includes a slotted seat 602, a counterweight roller 603, a servo motor 604, a flip gear 605, a slotted frame 606, a driving screw 607, a guide rod, a movable vertical plate 608 and a support plate 609. The slotted seat 602 is movably supported with a counterweight roller 603, and the counterweight roller 603 is provided with a circle of tooth grooves along the circumferential direction. The servo motor 604 is installed on the inner wall of the web of the slotted seat 602, and the output end of the servo motor 604 is installed with a flip gear 605 meshing with the tooth groove. The central axis of the counterweight roller 603 is fixedly connected with the slotted frame 606, and the driving screw 607 and the guide rod are installed in the slotted frame 606. The driving screw 607 is driven to rotate by an external motor through a belt transmission member.
