The present invention can complete the automatic assembly and automatic welding of bridge chords, save manual work, improve production efficiency, and ensure welding quality. The following is an explanation of an automatic assembly and welding device for bridge chords of the present invention in conjunction with the accompanying drawings.

Figure 5 , showing the structural schematic diagram of the support frame in the bridge chord automatic assembly welding equipment of the present invention. Figure 1 and Figure 5 , the automatic assembly welding equipment for bridge chords of the present invention is described.

[0059] like Figure 1 and Figure 5As shown, the automatic assembly and welding equipment for bridge chords of the present invention includes a support frame 20, a feeding mechanism 30, a pushing plate 21, a side positioning mechanism 40 and a welding mechanism 50; wherein the top of the support frame 20 is formed with a supporting surface 201 for placing the plates constituting the chord; the feeding mechanism 30 can be moved and adjusted relative to the support frame 20, and the feeding mechanism 30 is used to transport the plates constituting the chord to the support frame 20; the pushing plate 21 can be moved and adjusted along the support frame 20, and the pushing plate 21 can cooperate with the support frame 20 to position the plates placed thereon through movement and adjustment; the side positioning mechanism 40 is movably and adjustably arranged on both sides of the support frame 20, and the side positioning mechanism 40 can be telescopically adjusted to tighten the side of the corresponding plate; the position of the welding mechanism 50 is adjustable, and the welding mechanism 50 is used to perform welding operations on the plates placed on the support frame 20 to complete the automatic assembly and welding of the chord.

[0060] The working principle of the automatic assembly welding equipment for bridge chords of the present invention will be described below by taking the welding of two plates (a first plate and a second plate) as an example.

[0061] The feeding mechanism 30 picks up the first plate and transports the first plate to the support surface 201 of the support frame 20. After the first plate is placed, the push plate 21 is moved and adjusted so that the push plate 21 and the end of the support frame 20 clamp the first plate to fix the first plate. The moving and adjusting function of the push plate 21 enables it to position and fix plates of various sizes and specifications, and has a wide range of applications. Then the feeding mechanism 30 picks up the second plate and transports the second plate to the support frame 20, and places the second plate on the first plate in a designed posture. At this time, the feeding mechanism 30 does not move away, and the position of the side positioning mechanism 40 is adjusted so that the side positioning mechanism 40 clamps the two sides of the second plate, and then the feeding mechanism 30 is moved up, and then the position of the welding mechanism 50 is adjusted, and the connection between the first plate and the second plate is welded and fixed by the welding mechanism 50.

[0062] Of course, the automatic assembly welding equipment for bridge chords of the present invention is not limited to the automatic welding of two plates, and it can automatically weld plate components of various structural forms.

[0063] In a specific embodiment of the present invention, Figure 1 , Figure 3 and Figure 7 As shown, the side positioning mechanism 40 of the present invention includes a sliding mechanism 41 and a telescopically adjustable positioning plate 42 provided on the sliding mechanism 41; the sliding mechanism 41 can be moved and adjusted relative to the support frame 20; the positioning plate 42 can be moved closer to the support frame 20 or away from the support frame 20 by telescopic adjustment, and when the positioning plate 42 is extended and adjusted in the direction close to the support frame 20, it can tightly press against the side of the corresponding plate.

[0064] In this way, the corresponding positioning plates 42 on the side positioning mechanisms 40 on both sides of the support frame 20 can be used to clamp the two sides of the corresponding plate to achieve accurate positioning of the plate, so as to facilitate the subsequent welding operation of the welding mechanism 50.

[0065] The side positioning mechanisms 40 are arranged in pairs on both sides of the support frame 20. Multiple pairs of the side positioning mechanisms 40 can be arranged to achieve clamping and positioning of multiple plates at the same time. In the case where multiple ribs need to be arranged, the number of pairs of the side positioning mechanisms 40 can be consistent with the number of ribs to be clamped and positioned.

[0066] Furthermore, if Figure 7 As shown, a first telescopic driving member 43 drivingly connected to the positioning plate 42 is provided on the sliding mechanism 41, and the first telescopic driving member 43 is telescopically adjustable, and the telescopic adjustment direction of the first telescopic driving member 43 is perpendicular to the setting direction of the support frame 20. The telescopic movement of the positioning plate 42 is driven by the telescopic adjustment of the first telescopic driving member 43.

[0067] In a preferred embodiment, the first telescopic driving member 43 includes a first lead screw 432 and a first motor 431 drivingly connected to the first lead screw 432. The rotation of the first motor 431 can drive the first lead screw 432 to telescopically move and adjust relative to the sliding mechanism 41. The first motor 431 and the first lead screw 432 constitute a lead screw motor. The first lead screw 432 is arranged horizontally, and can move closer to or away from the support frame 20 during telescopic adjustment.

The side wheels 4133 on the two opposite sliding wheel groups 413 are against the outer side of the corresponding rail, so as to achieve the effect of clamping the two rails, and avoid the phenomenon of tipping in the process of positioning the corresponding plate. After the sliding wheel group 413 is moved along the first slide rail 24 and adjusted to a desired position, it can be fixed to the first slide rail 24 by a pin shaft, thereby fixing the position of the positioning plate 42. When it is necessary to adjust the position of the side positioning mechanism 40, the pin shaft is released, and the position of the side positioning structure 40 is moved by the sliding wheel group 413.

[0109] Furthermore, the bridge chord automatic assembly welding equipment of the present invention further comprises a pad, on which the support frame 20, the feeding mechanism 30, the side positioning mechanism 40 and the welding mechanism 50 of the present invention are all arranged.

[0110] The working process of the automatic assembly welding equipment for bridge chords of the present invention will be described below by taking the bridge chord structure of a preferred embodiment as an example.

[0111] First, the plates constituting the bridge chord are placed on the plate classification storage rack, and the plates include the bottom plate, top plate, side plate, rib plate, partition plate and bridge deck joint plate. Various joint plates constituting the bridge chord are placed on the joint plate storage rack.

[0112] Then the feeding mechanism picks up the top plate through the suction cup and places it on the support frame, and drives the push plate to move through the second telescopic drive member, so that the push plate and the limit plate clamp the top plate to complete the positioning of the top plate. The present invention first places the top plate on the support frame, so that after the chord rod is welded, it can be directly placed on the welding positioning frame without turning over. When picking up the corresponding plate, the suction cup of the feeding mechanism can generate magnetism by connecting the suction cup to electricity to adsorb and fix the plate, and then cut off the power after the plate is loaded and separate from the corresponding plate.

[0113] The suction cup frame of the feeding mechanism rotates 90 degrees, with the clamp facing downward, and the partition and rib are clamped by the clamp, and the partition is placed at the end of the top plate. After the partition is placed, the positioning disks of the side positioning mechanisms on both sides are extended and adjusted to clamp the partition. After the partition is clamped, the positioning disk is energized to generate magnetism and adsorb the corresponding partition, and the position of the welding mechanism is adjusted to complete the welding of the top plate and the partition. Similarly, the feeding, positioning and welding of the rib are completed through the above method.

[0114] The feeding mechanism then rotates the suction cup frame to reset, uses the suction cup to absorb the side panel, and then adjusts the suction cup frame to rotate 90 degrees, and sets the side panel upright on one side of the top panel. Before this, the side positioning mechanism at the side panel needs to be reset, and the positioning plate needs to be powered off and contacted with magnetic adsorption before resetting. After the side panel is placed in place, the positioning plate is adjusted to hold the side panel, and the side panel is welded to the top panel, partition and rib plate through the welding mechanism. The welding of the other side panel is completed in the same way.

[0115] The feeding mechanism then rotates the suction cup frame to reset, uses the suction cup to absorb the bottom plate, places the bottom plate on the partition plate and the rib plate, and uses the welding mechanism to weld the connection between the bottom plate and the side plate and the partition plate.

[0116] The loading mechanism then sucks up the bridge deck connecting plate through the suction cup and places the bridge deck connecting plate on the extension of the supporting top plate of the supporting frame. Before placing it, the positioning plate of the side positioning mechanism on that side is retracted first. After the bridge deck connecting plate is placed, the bridge deck connecting plate can be clamped by the plate clamping mechanism, the loading mechanism can be removed, and then the bridge deck connecting plate and the top plate are welded using the welding mechanism.

[0117] Adjust the position of the plate grinding mechanism, start the grinding disc to grind the corresponding positions on the sides of the bridge deck joint plate and the top plate. After grinding, use the plate clamping mechanism to clamp the corresponding joint plate and place it in the corresponding polished position, and the welding mechanism welds the joint plate.

[0118] Place the welded steel anchor box on the bracket of the welding positioning frame in advance, use the loading mechanism to clamp the welded chord body on the support frame and place it on the welding positioning frame, use the movable plate and the first positioning plate to clamp and position the chord body, and then use the second welding manipulator to weld the steel anchor box to the connecting part of the side plate of the chord, thereby completing the assembly welding of the bridge chord.

[0119] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
