Description

Technical Field

[0001] This utility model relates to the field of riveting machine technology, specifically a BL8 plate chain riveting machine with a novel transmission structure. Background Technology

[0002] In existing technologies, chain riveting relies on a motor-driven cam, which in turn causes four uprights to press down on the upper crossbeam, exposing and riveting the chain. Chain positioning and forward movement are both achieved by levering the cam linkage rod, with all actions dependent on mechanical linkage. This technology has many drawbacks: relying on a single motor for mechanical linkage results in significant wear and tear on the motor, requiring replacement every six months; the sprocket rotation, driven by the cam and rod, is prone to slippage and misalignment, leading to missed riveting; inconsistent riveting depth results in extremely poor chain quality; riveting positioning is inaccurate; and the entirely mechanical structure requires frequent and inconvenient maintenance. Utility Model Content

[0003] The purpose of this utility model is to provide a BL8 plate chain riveting press with a novel transmission structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a BL8 plate chain riveting machine with a novel transmission structure, comprising a frame, a hydraulic system installed on one side of the bottom of the frame, a PLC control cabinet installed on the other side of the bottom of the frame, a defect detection platform fixedly installed on one side of the top of the frame, a lower template fixedly installed on the other side of the top of the frame, two rotating guide wheels installed on the defect detection platform, a display and an image defect inspection mechanism fixedly installed on the defect detection platform, four sliding columns fixedly installed on the lower template, the four sliding columns being slidably connected to the four corners of the upper template respectively, a riveting hydraulic cylinder and an exposed hydraulic cylinder installed on the top of the upper template, an upper riveting die fixedly installed at the bottom output end of the riveting hydraulic cylinder, an upper exposed die fixedly installed at the bottom output end of the exposed hydraulic cylinder, and a lower riveting die, an exposed lower die, and a servo sprocket drive mechanism installed on the lower template.

[0005] The chain passes through the image defect inspection mechanism between the two guide wheels, performing appearance and defect inspection on the inner and outer plates and pins of the chain. An alarm is triggered if any abnormalities are detected. Only when the image inspection is successful will the sprocket of the servo sprocket drive mechanism drive the chain, precisely advancing one chain pitch. After the servo sprocket drive mechanism steps one pulse point, the positioning plates of the lower die and riveting die are positioned and locked by springs. The lower die lowering of the lower die lowers the chain, causing the upper die to lower as well. After the chain is exposed, the lower die returns to its original position. The riveting die lowering of the upper die lowers the chain, completing the riveting process, and then returns to its original position. A safety light grating ruler is installed; if detected during operation or standby, it will trigger an emergency stop device, disconnecting the power supply to prevent uncontrollable safety hazards during hydraulic cylinder lowering and sprocket operation.

[0006] Preferably, a control panel is fixedly installed on one side of the upper template. The hydraulic system is connected to the riveting hydraulic cylinder and the protruding hydraulic cylinder via pipelines. The control panel, display, hydraulic system, and image defect inspection mechanism are all connected to the PLC control cabinet. The PLC control cabinet can control and monitor the key points and actions of the equipment.

[0007] Preferably, a chain is also placed on the defect detection platform, and one end of the chain passes sequentially between two guide wheels, through the image defect inspection mechanism, the exposed lower mold and the riveting lower mold, and engages with the servo sprocket drive mechanism.

[0008] Preferably, the image defect inspection mechanism includes a camera, a light source, and a camera housing. The camera and light source are installed inside the camera housing. The camera is connected to a display via a wire. The image defect inspection mechanism detects defects in the chain.

[0009] Preferably, the upper and lower protrusion dies are correspondingly arranged, and the upper and lower riveting dies are correspondingly arranged. Each of the upper protrusion die and the lower riveting die includes two positioning plates, two springs, and two mounting seats. Positioning plates are mounted on the mounting seats via springs. The two positioning plates are correspondingly arranged, and the chain is held between the two positioning plates. The upper and lower protrusion dies, and the upper and lower riveting dies, perform the protrusion and riveting treatment of the chain.

[0010] Preferably, two safety light grid rulers are symmetrically installed on the lower template, and the safety light grid rulers are electrically connected to the PLC control cabinet.

[0011] Preferably, the hydraulic control system consists of a relief valve, a reversing valve, a hydraulic motor, a hydraulic pump, and air cooling. The hydraulic system controls the lifting and lowering of the exposed and riveting cylinders.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention employs a hydraulic system to control the lifting and lowering of the exposed and riveting cylinders, moving away from a purely mechanical approach. This eliminates the need for replacing the motor every six months, reducing motor wear and replacement costs. A control panel and display allow for the control and monitoring of key points and actions of the equipment. In case of abnormalities, the touchscreen will display corresponding alarm prompts, helping operators and maintenance personnel quickly locate and resolve the problem, improving operational convenience and shortening maintenance time. A servo driver controls the rotation of the drive sprocket, enabling precise chain positioning and preventing missed riveting caused by sprocket slippage or misalignment. An added image defect inspection mechanism allows for quality checks of the chain, ensuring chain compliance and improving product quality. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-3This utility model provides a BL8 plate chain riveting machine with a novel transmission structure, including a frame 1. A hydraulic system 2 is installed on one side of the bottom of the frame 1, and a PLC control cabinet 3 is installed on the other side of the bottom of the frame 1. A defect detection platform 11 is fixedly installed on one side of the top of the frame 1, and a lower template 20 is fixedly installed on the other side of the top of the frame 1. Two rotating guide wheels 14 are installed on the defect detection platform 11. A display 10 and an image defect inspection mechanism 12 are also fixedly installed on the defect detection platform 11. Four sliding columns 19 are fixedly installed on the lower template 20, and the four sliding columns 19 are slidably connected to the four corners of the upper template 17 respectively. A riveting hydraulic cylinder 8 and an exposed hydraulic cylinder 9 are installed on the top of the upper template 17. A riveting upper die 6 is fixed to the output end of the bottom of the riveting hydraulic cylinder 8, and an exposed upper die 15 is fixed to the output end of the bottom of the exposed hydraulic cylinder 9. A riveting lower die 5, an exposed lower die 21, and a servo sprocket drive mechanism 4 are also installed on the lower template 20.

[0020] A control panel 7 is fixedly installed on one side of the upper template 17. The hydraulic system 2 is connected to the riveting hydraulic cylinder 8 and the protruding hydraulic cylinder 9 through pipes. The control panel 7, the display 10, the hydraulic system 2 and the image defect inspection mechanism 12 are all connected to the PLC control cabinet 3.

[0021] Specifically, the PLC control cabinet 3 can control the opening and closing of the control panel 7, the display 10, the hydraulic system 2, and the image defect inspection mechanism 12.

[0022] A chain 13 is also placed on the defect detection platform 11. One end of the chain 13 passes through the two guide wheels 14, the image defect inspection mechanism 12, the exposed lower mold 21, and the riveting lower mold 5 in sequence, and meshes with the servo sprocket drive mechanism 4.

[0023] Specifically, the guide wheel 14 guides the chain 13, ensuring that the chain 13 moves along a predetermined path.

[0024] The image defect inspection mechanism 12 includes a camera, a light source, and a camera housing. The camera and light source are installed inside the camera housing, and the camera is connected to the display 10 via a wire.

[0025] Specifically, during the movement of chain 13, the image defect inspection mechanism 12 performs appearance and defect inspection on the inner plate, outer plate, pins, etc. of chain 13. The images captured by the camera are transmitted to the display 10 for the operator to observe. If any abnormality is found, an alarm is triggered in time.

[0026] The upper protruding die 15 and the lower protruding die 21 are set in correspondence, and the upper riveting die 6 and the lower riveting die 5 are set in correspondence. Both the lower protruding die 21 and the lower riveting die 5 include two positioning plates, two springs and two mounting seats. The positioning plates are mounted on the mounting seats by springs. The two positioning plates are set in correspondence, and the chain 13 is clamped between the two positioning plates.

[0027] Specifically, after the servo sprocket drive mechanism 4 drives the chain 13 forward by one chain pitch, the positioning plates of the protruding lower die 21 and the riveting lower die 5 are positioned and clamped by the springs to ensure the accuracy of subsequent protrusion and riveting operations. Subsequently, the protrusion hydraulic cylinder 9 drives the protrusion upper die 15 to descend, cooperating with the protrusion lower die 21 to complete the protrusion of the chain 13. After completion, the protrusion hydraulic cylinder 9 drives the protrusion upper die 15 to rise back to the original position. The riveting hydraulic cylinder 8 drives the riveting upper die 6 to descend, cooperating with the riveting lower die 5 to complete the riveting of the chain 13. After completion, the riveting hydraulic cylinder 8 drives the riveting upper die 6 to rise back to the original position.

[0028] Two safety light grid rulers 18 are also symmetrically installed on the lower template 20. The safety light grid rulers 18 are electrically connected to the PLC control cabinet 3.

[0029] Specifically, during equipment operation or standby, the safety light grating ruler 18 monitors in real time. If an abnormality is detected, it immediately transmits a signal to the PLC control cabinet 3, triggering the emergency stop device to disconnect the power supply and ensure the safe operation of the equipment.

[0030] Working principle: Chain 13 enters the image defect inspection mechanism 12 between guide wheels 14. After passing the inspection, the servo sprocket drive mechanism 4 drives chain 13 to move forward precisely by one chain pitch. The positioning plate clamps chain 13 under the action of spring. The protruding hydraulic cylinder 9 and the riveting hydraulic cylinder 8 drive the corresponding molds to complete the protruding and riveting work and then reset. Throughout the process, PLC control cabinet 3 controls and monitors through control panel 7 and display 10, and safety light grid ruler 18 ensures safety.
