Description

Technical Field

[0001] This invention relates to the field of cable tray manufacturing technology, specifically a cable tray manufacturing welding and forming tooling fixture. Background Technology

[0002] Ladder-type cable trays, as a type of cable tray, provide an open support channel for power cables, control cables, etc., with a unique trapezoidal structure. They offer excellent ventilation and heat dissipation performance, facilitating cable laying, maintenance, and future capacity expansion. At the same time, the hollow design effectively reduces its own weight, lowers installation costs, and can resist external mechanical damage, enhancing cable protection. They are widely used in factories, large-scale cable laying projects, high and low voltage power distribution rooms, and other places, helping to build an efficient and safe cable wiring system.

[0003] In the field of cable tray welding fixture technology, the current core technical problems are concentrated in the following aspects: For double-sided welding process, the traditional solution lacks a reliable automated flipping mechanism, which requires frequent manual disassembly and reassembly of the workpiece, resulting in efficiency and safety hazards such as long auxiliary time, large positioning error and risk of workpiece falling.

[0004] Furthermore, the independent operation of functional modules such as positioning, lifting, and welding makes it difficult for the tooling system to achieve adaptive adjustment of welding height and precise driving of the flipping process through collaborative control, resulting in poor process connection. In addition, traditional tooling, which relies on manual measurement or simple mechanical limit, is difficult to achieve high-precision alignment of side plates and steps and dynamic adaptation of multi-specification components in complex scenarios, resulting in unstable welding quality. Summary of the Invention

[0005] The purpose of this invention is to provide a tooling fixture for welding and forming cable trays, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable tray manufacturing and welding fixture, comprising an electric lifting platform fixed to the top of a base plate, a lifting mechanism for lifting the cable tray is provided above the electric lifting platform, a material placement component for loading the cable tray is provided between the electric lifting platform and the lifting mechanism, and control components that cooperate with the material placement component are provided on both sides of the electric lifting platform.

[0007] The top of the electric lifting platform is fixedly equipped with multiple sets of support frames at equal intervals. The top of the support frame is fixedly connected to a linear rail. The inside of the linear rail is slidably connected to a sliding seat. The top of the sliding seat is fixedly connected to a snap-fit ​​frame for placing the ladder included in the cable tray.

[0008] Furthermore, the material placement assembly includes two card plates and two reinforcing ribs for strengthening the connection between the two card plates. Both ends of the reinforcing ribs are fixedly connected to the corresponding side walls of the card plates. A receiving frame for placing the side plates of the cable tray is symmetrically fixedly installed on the adjacent side of the two card plates. An insertion hole is provided through the outer side of the receiving frame.

[0009] The receiving frame is internally slidably connected to an alignment plate, and a miniature electric push cylinder for driving the alignment plate to move horizontally is fixedly installed on one side of the two plates facing each other.

[0010] Furthermore, docking sleeve one and docking sleeve two are fixedly connected to the center of the two card plates respectively. The interior of docking sleeve one and docking sleeve two are respectively provided with a circular insertion groove and a polygonal driving groove. Positioning sleeves are fixedly connected to the opposite side of the two card plates.

[0011] Furthermore, the control component includes a sliding frame, a sliding plate is slidably connected inside the sliding frame, a support plate is fixedly connected to the top of the sliding plate, multiple sets of slots are opened through the outer side of the support plate, and a sliding frame that is slidably connected to the slots and engages with the positioning sleeve. An electric push rod is fixedly connected to the outer side of each of the two support plates, and the output end of the electric push rod is fixedly connected to the side wall of the sliding frame.

[0012] Furthermore, a sleeve is fixedly connected to the support plate near the first docking sleeve, and a sliding rod that is slidably connected inside the sleeve is slidably connected. An electric push rod is fixedly installed on the outside of the sleeve, and the output end of the electric push rod is fixedly connected to the sliding rod.

[0013] A rotating shaft that is fitted and inserted is fixedly connected to one side of the support plate near the second docking sleeve, and a motor for driving the rotating shaft to rotate is fixedly installed on the other side of the support plate.

[0014] Furthermore, an arc-shaped limiting slide bar is fixedly connected to the edge of one of the two card plates on opposite sides. The lifting mechanism includes an electric lifting seat, and an arc-shaped track is fixedly connected to the bottom end of the electric lifting seat. The arc-shaped limiting slide bar is slidably connected inside the arc-shaped track.

[0015] Furthermore, a miniature electric push cylinder is fixedly connected to the outer side of the arc-shaped track, and guide frames are fixedly connected to both sides of the bottom end of the arc-shaped track. A baffle is slidably connected inside the guide frame, and the output end of the miniature electric push cylinder is fixedly connected to the baffle.

[0016] Furthermore, welding guns for welding the gaps between the steps and side plates are provided on both sides of the electric lifting platform. A lead screw is movably connected inside the linear track through bearings. The sliding seat is threadedly connected to the lead screw through a threaded groove in the side wall. A motor for driving the lead screw to rotate is fixedly installed on the linear track.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention significantly improves the accuracy and stability of cable tray welding through a multi-component collaborative precision positioning structure design. In the material placement component, the corresponding design of the receiving frame and the side plate insertion hole, together with the external pin, enables the side plate to be quickly positioned and temporarily fixed, preventing it from falling off during the flipping process.

[0019] The miniature electric push cylinder drives the alignment plate to move horizontally, allowing for precise adjustment of the side plate position and ensuring accurate alignment between the side plate and the steps. The high-definition camera on the linear track works in conjunction with the sliding seat driven by the lead screw to precisely control the horizontal movement of the clamping frame via the motor, ensuring that multiple steps are evenly spaced and uniformly positioned between the side plates. This fundamentally solves the welding quality problem caused by component positioning deviations in traditional welding, providing high-precision basic assembly conditions for subsequent welding.

[0020] 2. The cooperation between the sliding frame and the positioning sleeve in the control component ensures the stability of the plate when it is under load. The motor drives the rotating shaft and the polygonal drive groove of the docking sleeve 2 in conjunction with the sliding guide of the arc-shaped limit slide bar in the arc-shaped track, which can realize the precise 180-degree rotation of the cable tray, so that the unwelded position of the side plate and the bottom of the ladder is rotated to the top. Double-sided welding can be completed without manual disassembly and reassembly. The cooperation between the mini electric push cylinder 2 and the baffle can seal the bottom of the arc-shaped track, further stabilizing the cable tray after rotation.

[0021] By reducing operational risks through structural stability design, and by working in tandem with the electric lifting platform and electric lifting seat, welding height adjustment can be achieved, further reducing auxiliary time in the welding process, avoiding the tedious operation of multiple clamping of traditional tooling, and significantly improving the production efficiency and automation level of cable tray welding.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: As Figures 1-9 As shown, a cable tray manufacturing welding fixture includes an electric lifting platform 1 fixed to the top of the base plate. The electric lifting platform 1 has welding guns 15 on both sides for welding the gap between the ladder and the side plate. The ladder cable is welded from multiple ladders and two side plates. Specifically, multiple ladders are arranged at equal intervals between the two side plates, and the two ends of the ladders are made to contact the corresponding side plate side walls, and then they are welded.

[0035] A lifting mechanism for lifting cable trays is provided above the electric lifting platform 1. A material placement component for loading cable trays is provided between the electric lifting platform 1 and the lifting mechanism. Adjustment components that cooperate with the material placement component are provided on both sides of the electric lifting platform 1. Multiple sets of support frames 2 are fixedly installed at equal intervals on the top of the electric lifting platform 1.

[0036] A linear track 3 is fixedly connected to the top of the support frame 2. A high-definition camera is installed on the top of the linear track 3. A sliding seat 4 is slidably connected inside the linear track 3. A lead screw is movably connected inside the linear track 3 through a bearing. The sliding seat 4 is threadedly connected to the lead screw through a threaded groove on its side wall. A motor 2 for driving the lead screw to rotate is fixedly installed on the linear track 3. A locking frame 5 for placing the ladders included in the cable tray is fixedly connected to the top of the sliding seat 4. In actual use, the linear track 3 is driven by the motor 2 to rotate the lead screw, thereby controlling the horizontal movement of the sliding seat 4 on the linear track 3. Under the action of the sliding seat 4, the locking frame 5 realizes the horizontal adjustment of the placement position of the ladders.

[0037] The material placement assembly includes two clamping plates 601 and two reinforcing ribs 602 to strengthen the connection between the two clamping plates 601. Both ends of the reinforcing ribs 602 are fixedly connected to the side walls of the corresponding clamping plates 601. A receiving frame 603 for placing the side plates of the cable tray is symmetrically fixedly installed on the adjacent side of the two clamping plates 601. A through-hole is provided on the outer side of the receiving frame 603. It should be noted that:

[0038] The insertion holes of the receiving frame 603 correspond to the insertion holes of the side plate. After the side plate is placed in the receiving frame 603, the receiving frame 603 and the side plate are temporarily fixed by the external pin to ensure that the side plate does not fall off during the flipping process.

[0039] The receiving frame 603 is internally slidably connected to an alignment plate 604. On the opposite side of the two clamping plates 601, a miniature electric push cylinder 605 is fixedly installed to drive the alignment plate 604 to move horizontally.

[0040] Two card plates 601 are respectively fixedly connected to the center of the two card plates 601 with a first docking sleeve 606 and a second docking sleeve 607. The first docking sleeve 606 and the second docking sleeve 607 are respectively provided with a circular insertion groove and a polygonal driving groove. The two card plates 601 are fixedly connected to the opposite side with a positioning sleeve 608.

[0041] Example 2: The control component includes a slide frame 701, a slide plate 702 is slidably connected inside the slide frame 701, a lead screw 2 is movably connected inside the slide frame 701 through a bearing, and a motor 3 for driving the lead screw 2 to rotate is fixedly installed on the outside of the slide frame 701. Meanwhile, the slide plate 702 is threadedly connected to the lead screw 2 through a threaded hole in its side wall, and a support plate 703 is fixedly connected to the top of the slide plate 702.

[0042] Multiple slots are formed through the outer side of the support plate 703, and a sliding frame 704 that is slidably connected in the slots and engages with the positioning sleeve 608. An electric push rod 705 is fixedly connected to the outer side of both support plates 703, and the output end of the electric push rod 705 is fixedly connected to the side wall of the sliding frame 704. By fixing the positioning sleeve 608 on the outer side of the clamping plate 601, and by cooperating with the sliding frame 704 and the positioning sleeve 608, the stability of the clamping plate 601 during the load-bearing process is ensured.

[0043] A sleeve 706 is fixedly connected to the side of the support plate 703 near the docking sleeve 606. A sliding rod 707 is slidably connected inside the sleeve 706. An electric push rod 2 is fixedly installed on the outside of the sleeve 706, and the output end of the electric push rod 2 is fixedly connected to the sliding rod 707.

[0044] A rotating shaft 708 is fixedly connected to one side of the support plate 703 near the docking sleeve 607, and a motor 8 for driving the rotating shaft 708 to rotate is fixedly installed on the other side of the support plate 703.

[0045] Arc-shaped limiting slide bars 9 are fixedly connected to the edges of the two card plates 601 on opposite sides. The lifting mechanism includes an electric lifting seat 10, which is located below the crossbeam above the processing workshop. It should be explained here that the electric lifting seat 10 is an existing device used to drive the arc-shaped track 11 to lift synchronously. The bottom end of the electric lifting seat 10 is fixedly connected to the arc-shaped track 11, and the arc-shaped limiting slide bars 9 are slidably connected inside the arc-shaped track 11.

[0046] A miniature electric push cylinder 12 is fixedly connected to the outer side of the arc-shaped track 11. Guide frames 13 are fixedly connected to both sides of the bottom end of the arc-shaped track 11. Baffles 14 are slidably connected inside the guide frames 13. The output end of the miniature electric push cylinder 12 is fixedly connected to the baffles 14. The miniature electric push cylinder 12 drives the baffles 14 to move horizontally inside the guide frames 13, thereby realizing the flexible sealing and opening of the bottom ends of the arc-shaped track 11.

[0047] As can be seen from Embodiment 1 and Embodiment 2, the working principle of the present invention is as follows:

[0048] First, the ladder step is placed on top of the snap-fit ​​frame 5, and the lead screw in the linear rail 3 on one side is rotated by the corresponding motor 2. Then, the horizontal movement of the ladder step is achieved through the sliding seat 4 and the snap-fit ​​frame 5. The high-definition camera set on the top of the linear rail 3 is used to adjust the horizontal position of the ladder step to ensure that the positions of multiple ladder steps placed in the corresponding snap-fit ​​frame 5 are consistent.

[0049] Then, place both ends of the side plate into the corresponding receiving frame 603, and use the micro electric push cylinder 605 to control the alignment plate 604 to move horizontally within the receiving frame 603. The alignment plate 604 at both ends of the side plate adjusts the position of the side plate until the insertion hole of the receiving frame 603 is connected to the insertion hole of the side plate. Then, use external pins to temporarily fix the receiving frame 603 and the side plate to ensure that the side plate does not fall off during the flipping process. After the ladder and the side plate are placed, use the welding gun 15 to weld and fix the side plate and the ladder.

[0050] After the welding gun 15 welds the side plate to the top of the step, the bottom of the connection between the side plate and the step cannot be effectively welded. In order to achieve the flipping of the side plate and the step, the sliding frame 704 inserted in the positioning sleeve 608 needs to be pulled out. Specifically, the electric push rod 705 is used to drive the sliding frame 704 to move horizontally until one end of the sliding frame 704 is separated from the contact with the positioning sleeve 608.

[0051] Before the sliding frame 704 is removed from the positioning sleeve 608, the two electric lifting seats 10 need to be driven to drive the arc track 11 to descend synchronously until the center of the arc track 11 coincides with the center of the arc limit slide bar 9. Then the sliding frame 704 is removed from the positioning sleeve 608, the electric lifting platform 1 descends, and space is reserved for the card plate 601 to drive the cable tray to flip. The motor 1 8 drives the rotating shaft 708 to rotate. Since the rotating shaft 708 is matched with the polygonal drive groove of the docking sleeve 2 607;

[0052] At this time, the clamping plate 601 is synchronously deflected under the action of the reinforcing rib 602, the first docking sleeve 606 and the slide rod 707. During the deflection process, the arc-shaped limiting slide bar 9 on the outer side of the clamping plate 601 gradually slides into the arc-shaped track 11 until one end of the arc-shaped limiting slide bar 9 contacts the baffle 14. Then, the micro electric push cylinder 12 on the other side is controlled to drive the baffle 14 to slide in the guide frame 13 until the baffle 14 seals the bottom of one end of the arc-shaped track 11.

[0053] At this time, the snap-fit ​​plate 601 is fixed after being rotated 180 degrees by the arc-shaped limiting slide bar 9, the arc-shaped track 11 and the baffle 14. At this time, the side plate and the bottom of the step that are not welded are rotated to the top. After the snap-fit ​​plate is rotated 180 degrees and fixed, the slide plates 702 on both sides of the electric lifting platform 1 move in opposite directions at the same time, causing the slide bar 707 and the rotating shaft 708 to disengage from the docking sleeve 1 606 and the docking sleeve 2 607 respectively, so that the electric lifting seat 10 can drive the electric bridge to descend.

[0054] After the cable tray is rotated 180 degrees, the electric lifting seat 10 lowers the electric cable tray to a height that is convenient for the welding gun 15 to weld. Then the welding gun 15 welds the bottom of the rotated cable tray.

[0055] After welding is completed, the electric lifting seat 10 drives the electric bridge to rise until the center of the arc track 11 coincides with the center of the slide rod 707. Then, the electric push rod 2 installed on the outside of the sleeve 706 drives the slide rod 707 to move and reconnect with the docking sleeve 1 606. The rotating shaft 708 is connected with the docking sleeve 2 607 under the action of the sliding plate 702. The baffle 14 releases the blockage on the bottom of the arc track 11 under the action of the miniature electric push cylinder 2 12.

[0056] Subsequently, motor 8 drives shaft 708 to rotate, and further through the synchronous rotation of docking sleeve 607 and clamping plate 601, the welded cable tray is caused to deflect 180 degrees in the opposite direction until the arc-shaped limit slide bar 9 slides out from the arc-shaped track 11. Then the electric lifting seat 10 rises and the pin used to fix the side plate of the cable tray is pulled out from the receiving frame 603 so that the welded cable tray can be taken out.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
