Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy ladder processing technology, and in particular to a fully automatic riveting equipment for aluminum alloy ladders. Background Technology

[0002] A ladder, an everyday tool, consists of two long, thick rods as sides, with a crossbar running through the middle for easy climbing. Aluminum alloy ladders are made of high-strength aluminum alloy profiles, making them lightweight and easy to carry. Advanced square tube extrusion and riveting technology ensures good safety, and they are equipped with sturdy, non-slip feet. Aluminum alloy is an alloy based on aluminum with added amounts of other alloying elements; it is one of the lightweight metal materials. Aluminum alloy ladders can be processed through riveting. Riveting, or rivet connection, is a mechanical term referring to the method of using axial force to thicken the rivet rod inside the rivet hole of a part and form a rivet head, thus connecting multiple parts. Riveting processing requires a fully automatic riveting machine for aluminum alloy ladders.

[0003] Modern fully automated riveting equipment for aluminum alloy ladders can basically meet people's needs, but some problems still exist, as detailed below:

[0004] 1. The problem of difficulty in adjusting the position of the rivet joint in fully automatic riveting equipment for aluminum alloy ladders: When riveting a ladder, there are multiple positions on a ladder that need to be riveted, and the position of the rivet joint often needs to be adjusted. Manual adjustment will waste manpower.

[0005] 2. The problem of difficulty in limiting the movement of aluminum alloy ladders in fully automatic riveting equipment. During riveting, the ladder is prone to displacement, which can cause processing problems. Utility Model Content

[0006] The purpose of this invention is to provide a fully automatic riveting device for aluminum alloy ladders, which solves the defects of existing fully automatic riveting devices for aluminum alloy ladders, such as difficulty in adjusting the position of the riveting joint and difficulty in limiting the ladder.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fully automatic riveting device for aluminum alloy ladders, including support legs;

[0008] The main structure is installed at the top of the support leg, and the main structure includes a workbench, a box, a mounting frame and a top plate. The box is installed at the top of the support leg, and the workbench is installed at the top of the box.

[0009] A movable plate is installed at the top of the workbench, a limiting structure is installed at the top of the movable plate, a mounting frame is installed at one end of the top of the workbench, a top plate is installed at the top of the mounting frame, a hydraulic cylinder is installed at the top of the top plate, a hydraulic rod is installed at the bottom of the hydraulic cylinder, a rivet joint is installed at the bottom of the hydraulic rod, and an adjustment mechanism is installed inside the top plate.

[0010] The adjustment mechanism includes a rotary motor, an adjustment block, a guide rod, a rotating shaft, and a chain. The rotary motor is installed at the top of the top plate, and a chain is installed at the top of the rotary motor. A rotating shaft is installed inside the chain, and an adjustment block is installed on one side of the chain. An adjustment block is also installed on one side of the adjustment block.

[0011] In use, after the ladder parts are first limited, the servo motor drives the screw to rotate. The rotation of the screw drives the moving block, which is connected to it by a thread, to move. The movement of the moving block drives the moving plate to move. The connecting rod passes through the moving block and guides the moving block. The movement of the moving plate can adjust the movement of the top part, so the part can move left and right. The rivet head can move back and forth, so that the part can be riveted at different positions. The hydraulic cylinder drives the hydraulic rod to extend and retract. The extension and retraction of the hydraulic rod can adjust the raising and lowering of the rivet head. The operation of the rivet head can perform riveting processing on the rivets.

[0012] Furthermore, the workbench is equipped with a moving mechanism, which includes a moving block, a screw, a servo motor, and a connecting rod. The moving block is installed at the bottom of the moving plate, and a screw passes through the middle of the moving block. A servo motor is movably connected to one side of the screw. The movement of the moving block can drive the moving plate to move, and the movement of the moving plate can adjust the movement of the top part, so that the part can move left and right.

[0013] Furthermore, connecting rods extend through both ends of the movable block, and the connecting rods are symmetrically distributed about the central axis of the movable block. The connecting rods extend through the movable block and can guide the movable block.

[0014] Furthermore, the limiting structure includes a mounting plate, a limiting plate, anti-slip texture, a telescopic rod, and a threaded rod. The mounting plate is installed on the top of the movable plate. A telescopic rod is installed at one end of the mounting plate, and a limiting plate is installed at one end of the telescopic rod. A threaded rod is movably connected to one end of the limiting plate. The mounting plate and the limiting plate are connected by the threaded rod and the telescopic rod, forming a threaded connection. Rotation of the threaded rod can adjust its movement, and movement of the threaded rod can drive the limiting plate to move. The movement of the limiting plate can clamp the part to be processed in the middle, preventing the part from shifting during processing. The telescopic rod can extend and retract, and can guide the limiting plate.

[0015] Furthermore, one end of the limiting plate is provided with anti-slip texture, which is arranged at equal intervals on one end of the limiting plate. The anti-slip texture can enhance the friction of the limiting plate.

[0016] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the mounting plate is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the mounting plate are threadedly connected, and the rotation of the threaded rod can adjust the movement of the threaded rod.

[0017] Furthermore, the bottom end of the adjustment block is provided with a slider, and the inside of the top plate is provided with a sliding groove. The adjustment block and the top plate form a sliding structure, and the adjustment block can slide along the sliding groove.

[0018] The fully automatic riveting equipment for aluminum alloy ladders provided by this utility model has the following advantages: A rotary motor is installed at the bottom of the top plate. When the rotary motor works, it drives the rotating shaft to rotate, which in turn drives the chain to move. The chain is provided with equally spaced teeth. The groove on one side of the adjusting block meshes with the chain. The rotation of the chain drives the adjusting block to move, which in turn adjusts the front and rear position of the riveting head, allowing the riveting head to adapt to different situations. A guide rod passes through the adjusting block and guides the adjusting block, thereby achieving the purpose of facilitating the adjustment of the riveting head position in the fully automatic riveting equipment for aluminum alloy ladders.

[0019] An installation plate is mounted on the top of the moving plate. The installation plate and the limiting plate are connected by a threaded rod and a telescopic rod. The threaded rod and the installation plate form a threaded connection. Rotating the threaded rod can adjust its movement, which in turn moves the limiting plate. The moving limiting plate can clamp the parts to be processed in the middle, preventing the parts from shifting during processing. The anti-slip texture can enhance the friction of the limiting plate. The telescopic rod can extend and retract, guiding the limiting plate. This achieves the purpose of facilitating the limiting of the ladder in the fully automatic riveting equipment for aluminum alloy ladders. Attached Figure Description
