Description

Technical Field

[0001] This application relates to the field of riveting and welding automation technology, specifically a material conveying mechanism for a riveting and welding workstation. Background Technology

[0002] In modern riveting and welding production, especially in fully automated riveting and welding workstations that pursue high efficiency, high quality, and low cost, the rapid, precise, and automated transfer of materials between workstations is a key factor in improving overall production efficiency. However, currently widely used material handling technologies and equipment have significant limitations when facing the demands of automated workstations, mainly in the following aspects:

[0003] 1. High reliance on manual labor and low efficiency: The most common material handling method relies on operators manually pushing flatbed carts or heavy material carts. This method is not only extremely labor-intensive and requires high physical fitness from the operators, but it is also slow and time-consuming.

[0004] 2. Poor flexibility and low efficiency: Although the bridge cranes or cantilever cranes commonly used in the workshop can move materials, they can often only move one piece of material at a time, which is inefficient.

[0005] In summary, existing material handling devices (manually driven trolleys or workshop hoisting equipment) generally suffer from problems such as low efficiency, time and labor costs, low automation, and difficulty in integrating into fully automated production lines. Utility Model Content

[0006] This application provides a material conveying mechanism for a riveting and welding workstation, which can realize the rapid transport of materials in batches. At the same time, the size of the transfer platform can be adjusted according to the size of the materials, further improving adaptability and effectively solving the problems in the prior art.

[0007] To achieve the above objectives, this application provides the following technical solution: a material conveying mechanism for a riveting and welding workstation, comprising:

[0008] Four L-shaped trays for holding materials;

[0009] The left and right adjacent L-shaped trays are connected by multiple guide rods. One end of each guide rod is fixed to the outside of an L-shaped tray, and the other end passes through the positioning hole on the outside of the adjacent L-shaped tray.

[0010] The adjacent L-shaped trays are fixedly connected by a support frame;

[0011] Each L-shaped pallet is equipped with a hydraulic telescopic rod on its lower surface. The four hydraulic telescopic rods rise and fall synchronously and are controlled by the hydraulic station in the power box.

[0012] Each hydraulic telescopic rod has a base installed at its lower end, and a traveling mechanism is provided on the lower surface of the base.

[0013] A hydraulic telescopic rod and a positioning rod are provided between the left and right adjacent bases. The positioning rod is parallel to the hydraulic telescopic rod, with one end fixed to the outside of the base by a mounting plate and the other end passing through the U-shaped positioning plate on the adjacent base.

[0014] The outer side of the positioning rod is provided with axially linearly distributed positioning grooves. The outer side of the U-shaped positioning plate is threaded with a headed stud. The end of the headed stud can be inserted into the positioning groove to lock the positioning rod.

[0015] Preferably, the power box is disposed on the upper surface of the second support frame, and the second support frame is connected to the front and rear adjacent bases.

[0016] Preferably, the hydraulic station includes a hydraulic pump and a hydraulic oil tank, both located inside the power box.

[0018] Preferably, the traveling mechanism includes a main shaft, a stepper motor, a gear, a U-shaped frame, a traveling wheel, and a stepper motor.

[0019] The upper end of the spindle is rotatably connected to the base via a bearing;

[0020] Stepper motor 1 is fixed inside the protective cover, and its output shaft meshes with gear 1 on the main shaft through gear 2;

[0021] The lower end of the main shaft is connected to a U-shaped frame, the traveling wheel is located inside the U-shaped frame, and the second stepper motor is fixed to the outside of the U-shaped frame and its output shaft is connected to the axle of the traveling wheel.

[0022] Preferably, the protective cover covers the meshing part of gear one and gear two and is fixed to the lower surface of the base.

[0023] Preferably, the stepper motor drives the main shaft to rotate through gear one and gear two, thereby realizing the steering control of the traveling wheel.

[0024] Preferably, the second stepper motor directly drives the travel wheel to rotate in order to achieve linear movement.

[0025] Preferably, when the hydraulic telescopic rod extends or retracts, it drives the adjacent left and right bases to move towards or away from each other, and synchronously adjusts the distance between the L-shaped support plates.

[0026] Preferably, the four hydraulic telescopic rods are raised and lowered synchronously to adjust the overall height of the L-shaped support plate.

[0027] Compared with the prior art, the beneficial effects of this application are:

[0028] 1. This application achieves batch loading and transfer of materials by setting up four synchronously lifting L-shaped pallets and an adjustable spacing structure. The L-shaped pallets can carry multiple stacked materials at the same time, improving the material transfer efficiency. The traveling mechanism is driven by stepper motor 2 to drive the traveling wheels to achieve autonomous walking. Stepper motor 1 controls the steering through a gear set, without the need for manual intervention.

[0030] 3. The linear positioning groove of the positioning rod and the headed stud form a mechanical interlock to prevent the hydraulic telescopic rod 2 from being accidentally displaced during transportation; the protective cover covers gear 1 and gear 2 to prevent foreign objects from entering and causing transmission failure; support frame 1 and support frame 2 are respectively connected to the front and rear pallets and the base to form a rigid frame structure to ensure overall stability; after the material is placed, only the hydraulic clamping and travel program needs to be started to complete the transfer, which greatly reduces labor intensity.

[0038] Please see Figure 1-4 This application provides the following technical solution: a material conveying mechanism for a riveting and welding workstation, including an L-shaped pallet 3 for holding materials. The number of L-shaped pallets 3 is four. The left and right adjacent L-shaped pallets 3 are connected together by multiple guide rods 1. The front and rear adjacent L-shaped pallets 3 are fixedly connected together by a support frame 2. One end of the guide rod 1 is welded to the outer side of one side L-shaped pallet 3, and the other end passes through a positioning hole set on the outer side of the other side L-shaped pallet 3. By controlling the length of the guide rod 1 inserted into the positioning hole, the distance between the left and right L-shaped pallets 3 can be adjusted, thereby realizing the adjustment of the size of the material holding area.

[0039] The lower surfaces of the four L-shaped pallets 3 are each equipped with a hydraulic telescopic rod 4 for controlling the lifting and lowering of the L-shaped pallets 3. The four hydraulic telescopic rods 4 lift and lower synchronously at the same speed. The extension and retraction of the four hydraulic telescopic rods 4 are controlled by a hydraulic station located inside the power box 9. The hydraulic station includes a hydraulic pump and a hydraulic oil tank.

[0040] Each of the four hydraulic telescopic rods 4 has a base 5 installed on its lower end. The lower surface of the base 5 is equipped with a traveling mechanism 8. A support frame 13 is provided between two adjacent bases 5. A power box 9 is provided on the upper surface of the support frame 13. A rechargeable battery pack is installed inside the power box 9.

[0041] A hydraulic telescopic rod 7 and a positioning rod 6 are installed between two connected bases 5. The hydraulic telescopic rod 7 can adjust the distance between the two connected bases 5 by telescoping. The positioning rod 6 is arranged parallel to the hydraulic telescopic rod 7. One end of the positioning rod 6 is fixed to the outer side of the base 5 by the mounting plate 12. The other end of the positioning rod 6 passes through the U-shaped positioning plate 10 set on the other base 5. The outer side of the positioning rod 6 has positioning grooves evenly distributed linearly along the axial direction. The outer side of the U-shaped positioning plate 10 is threaded with a stud 11. When the stud 11 is locked, the end of the stud 11 can be inserted into the positioning groove, thereby fixing the position of the positioning rod 6 and locking the distance between the two connected bases 5.

[0042] The traveling mechanism 8 includes a main shaft 83, the upper end of which is rotatably connected to a base 5 via a bearing. A protective cover 88 is mounted on the lower surface of the base 5. A stepper motor 81 is installed inside the protective cover 88. A gear 87 is mounted on the output shaft of the stepper motor 81 via a coupling. The main shaft 83 passes through the protective cover 88. A gear 82 is mounted on the outer side of the main shaft 83, meshing with the gear 87. The stepper motor 81 drives the main shaft 83 to rotate. A U-shaped frame 86 is mounted on the lower end face of the main shaft 83. A traveling wheel 85 is rotatably connected to the inner side of the U-shaped frame 86. A stepper motor 84 is mounted on the outer side of the U-shaped frame 86. The output shaft of the stepper motor 84 is connected to the axle of the traveling wheel 85 via a coupling. The stepper motor 84 drives the traveling wheel 85 to rotate, thus achieving the movement of the conveying mechanism.

[0043] In use, the material is hoisted onto the upper surface of the L-shaped pallet 3. The materials can be stacked together. The hydraulic telescopic rod 7 retracts, causing the L-shaped pallets 3 on the left and right sides to move closer to each other. The four L-shaped pallets 3 clamp the materials simultaneously.

[0044] Then stepper motor 2 84 is started, which drives the travel wheel to rotate and move the entire equipment along the planned path. During the movement, stepper motor 1 81 can drive the travel wheel 85 to rotate through the gear transmission system, thereby turning the equipment as a whole and quickly transporting the materials to be processed to the automated riveting and welding workstation.

[0045] When transporting long materials, multiple transport units can be used in series.

[0046] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
