Detailed Implementation
[0041] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0042] This embodiment discloses an automatic assembly and testing machine for dampers, such as... Figure 1-7 As shown, the equipment includes a workbench 11, which serves as the support platform for the entire device, supporting the turntable 12 and related devices at each workstation. It provides a stable foundation for the flow of workpieces and the operation of each process, ensuring smooth operation of the equipment. The turntable 12 is located at the center of the workbench 11, and a drive assembly 13 is located at the lower end of the turntable 12, driving the rotation of the turntable 12. The turntable 12, situated at the center of the workbench 11, is the core component for workpiece flow. Through rotation, it sequentially transfers workpieces to various workstations, achieving continuous production. Multiple workstations are arranged around the circumference of the turntable 12, allowing workpieces to be processed sequentially in different processes, thus improving production efficiency.
[0043] The top plate 14 is located above the workbench 11. Multiple support columns are provided between the top plate 14 and the workbench 11. The upper and lower ends of the support columns are fixedly connected to the top plate 14 and the workbench 11 by bolts. The top plate 14 provides an installation position for the pressing mechanism 4, the damping testing mechanism 5, the sorting mechanism, the pulling mechanism 8, and the marking mechanism 9, so that these mechanisms can be stably arranged at a suitable height, which is convenient for operating the workpiece.
[0044] The base plate 15 is fixed below the workbench 11. Multiple support columns are provided between the base plate 15 and the workbench 11, with their upper and lower ends fixedly connected to the base plate 15 and the workbench 11 by bolts. The base plate 15 is used to install power and oil injection devices such as the hydraulic station 22 and oil tank 23, providing necessary power support and hydraulic oil storage for the equipment's operation. The multiple support columns between the top plate 14, the base plate 15, and the workbench 11 support and stabilize the entire equipment structure, ensuring accurate relative positions of components during operation and reducing vibration and shaking.
[0045] The workbench 11 is equipped with multiple workstations, and the top plate 14 is equipped with multiple actuating mechanisms.
[0046] The workbench 11 has multiple stations including feeding, oiling, kit assembly 3, pressing, damping test, sorting and sealing, drawing and marking and unloading stations 10;
[0047] Loading station 1: The operator places the damper workpiece to be assembled at this position, and the turntable 12 transfers the workpiece to the next station according to the overall machine cycle, thus realizing the initial loading of the workpiece.
[0048] Oil injection station: After the turntable 12 rotates to bring the workpiece to the station, the oil pump 21 on the side of the oil tank 23 draws hydraulic oil from the oil tank 23 to perform the oil injection process for the damper. Through the control of the oil pump 21, the amount and speed of oil injection can be precisely controlled to ensure the quality of oil injection for the damper. After the oil injection is completed, the station is in standby mode, waiting for the turntable 12 to transfer the workpiece to the next station.
[0049] Combination station: Turntable 12 continues to rotate. When the workpiece reaches this station, the piston rod assembly is manually placed into the oiled kit to complete the combination operation of the damper.
[0050] Pressing station: After the turntable 12 rotates to bring the workpiece to the station, the pressing head of the pressing mechanism 4 on the top plate 14 descends to perform pressing. The pressing head is equipped with an automatic guiding system, which can automatically adjust its position during the pressing process to ensure the accuracy and stability of pressing, so that the pressing qualification rate reaches 100%. After pressing is in place, a signal is given and the station is ready for standby.
[0051] Damping test station: After the turntable 12 rotates and transfers the workpiece to this station, the upper test head of the damping test mechanism 5 automatically grabs the damper for testing. This mechanism uses a shock absorber demonstration machine for testing, which can accurately measure the damping force of the damper and provide reliable data support for subsequent sorting. After the test is completed, the gripper is released and the equipment returns to zero for standby.
[0052] Sorting and Sealing Station: After the turntable 12 rotates and brings the workpiece to this station, the sorting mechanism makes a judgment based on the information provided by the damping test station. If the damping force is qualified, the sealing operation is performed; if the damping force is unqualified, the gripper extends to remove the defective product at this station and throws it into the discharge chute so that it flows into the defective product box.
[0053] Pulling and marking station: After the turntable 12 rotates and transfers the workpiece to this station, the upper jaw of the pulling mechanism 8 automatically grabs the workpiece to perform the pulling operation, and checks the performance and reliability of the damper. At the same time, the marking mechanism 9 located below the pulling mechanism 8 starts to work. The marking mechanism 9 includes a marking machine and a lifting platform. The marking machine is fixed on the lifting platform, and the lifting platform is fixed on the surface of the worktable 11. By adjusting the lifting platform, the marking machine can accurately mark the surface of the damper.
[0054] Unloading station 10: After the turntable 12 rotates to bring the workpiece to this station, the unloading station 10 receives the workpiece that has passed the damping test, been pulled to its longest length and marked, and directly puts it into the next process to complete the entire production process.
[0055] Multiple workstations are arranged in a circle around the center of workbench 11.
[0056] The top plate 14 is provided with a pressing mechanism 4, which is used for pressing the damper kit. Its pressing head is equipped with an automatic alignment system. During the pressing process, the automatic alignment system can monitor the position and attitude of the pressing head in real time and automatically adjust according to the actual situation to ensure that the pressing head is accurately aligned with the kit for pressing, thereby improving the accuracy and stability of pressing and ensuring the passing rate of pressing.
[0057] The damping testing mechanism 5 is used for damping testing of the damper. The damping testing mechanism 5 adopts a shock absorber demonstration machine for testing. The upper testing head of the mechanism can automatically grab the damper and test it according to the set testing program to accurately obtain the damping force data of the damper, providing a basis for subsequent sorting.
[0058] The sorting mechanism, based on the information provided by the damping test mechanism 5, is used to sort whether the dampers are good or bad products. When the damping force is qualified, the sealing operation is performed. When the damping force is unqualified, the gripper extends to take out the defective product at this station and throw it into the discharge chute, so that it flows into the defective product frame, thereby realizing the automatic sorting of the dampers.
[0059] The pulling mechanism 8 is used to pull the damper to its maximum stroke; the pulling mechanism 8 is used to test the performance and reliability of the damper. Its upper jaw can automatically grasp the workpiece and perform a pulling operation according to the set pulling force and stroke to simulate the stress condition of the damper in actual use and test whether its performance meets the requirements.
[0060] The marking mechanism 9 is used to mark the surface of the damper, and the marking mechanism 9 is located below the drawing mechanism 8.
[0061] The marking mechanism 9 includes a marking machine and a lifting platform. The marking machine is fixed on the lifting platform, and the lifting platform is fixed on the surface of the worktable 11.
[0062] The drive assembly 13 includes a drive motor and a reducer. The output end of the drive motor is provided with a reducer, and the output end of the reducer is provided with a rotating shaft. The end of the rotating shaft is fixedly connected to the turntable 12.
[0063] The base plate 15 is equipped with a hydraulic station 22, which provides hydraulic power to the actuating mechanisms of the entire device. The hydraulic station 22 can stably output hydraulic oil and deliver it to each actuating mechanism through hydraulic pipelines, ensuring that mechanisms such as the pressing mechanism 4 and the pulling mechanism 8 that require hydraulic power can operate normally.
[0064] The oil tank 23 is filled with hydraulic oil. An oil pump 21 is provided on the side of the oil tank 23. The oil pump 21 is used to draw hydraulic oil from the oil tank 23 and inject it into the damper at the oil injection station.
[0065] A control method for an automatic assembly and testing machine for dampers and its testing method includes the following steps:
[0066] S1. The worker manually loads the workpiece and places it at the loading position. The turntable 12 then transfers the workpiece to the next station according to the overall machine cycle.
