Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of noise reduction test benches, and particularly relates to a noise reduction test bench with an embedded automatic handling and grasping device installed therein. Background Art
[0002] When overhauling railway locomotives and vehicle components, many different types of valve bodies need to complete performance tests on corresponding types of test benches according to the regulations in railway standards. These valve bodies need to be transported from fixed positions on the overhaul production line to the fixture positions on the test bench, and then clamped by the fixtures for testing. Currently, in the working scenario, there are the following several handling methods. One is to manually transport the valve body to be tested from the production line to the test bench fixture for installation. The second is to use an industrial robot to grasp the valve body from the production line, align the valve body and the fixture installation surface, and then clamp it. The third is to use a structure with a truss carrying a sliding table. Build a truss around the test bench, and the sliding table relies on the truss to move and install the valve body on the fixture. All of these three methods have defects. When using the manual method for handling and installation, due to the heavy weight of the valve body to be tested and the large workload, it will cause physical damage to the operator. When using a multi-axis industrial robot for handling and clamping, no one is allowed to enter within the movement range of the robot, which limits the operator's activity space, hinders the normal work process, and cannot be applied to the actual work site. When using the structure method with a truss carrying a sliding table, columns and guardrails need to be set up, which expands the floor area of the test bench. Moreover, the operator needs to frequently enter and exit the guardrail during the work process, reducing the work efficiency and having very low applicability.
[0003] At the same time, various valve body performance test benches all use compressed air for work, and strong noise will be generated when compressed air is discharged during the process. Currently, there are corresponding noise reduction test benches. However, the methods of using robots and trusses for valve body grasping and handling cannot be implemented on the noise reduction test bench. Summary of the Utility Model

[0024] This embodiment mainly describes the control method of the automatic handling and grasping device embedded inside the test bench. The following is the control process of the handling and grasping device moving from the original position to the position of conveyor line 15, grasping the valve body, moving to the fixture position, installing the valve body, and then returning to the origin.
[0025] The PLC control system determines whether the tray 16 carrying the valve body on the conveyor line 15 is in place according to the feedback signal of the travel switch of the conveyor line 15. If it is not in place, subsequent actions are stopped. After it is in place, the PLC system polls the signal of the magnetic switches on the first automatic door 6, the second automatic door 7, the third automatic door 8, the fixture, and the cylinder to check whether they are all in the origin position. If not in the origin position, a check is prompted. In the origin position, the PLC controls the first automatic door 6 to close, the second automatic door 7 and the third automatic door 8 to open, and the magnetic switches of the first automatic door 6, the second automatic door 7, and the third automatic door 8 feed back signals to the PLC system to determine whether they are in place. If not in place, a check is prompted.
[0026] After it is in place, the PLC system controls the jaws of the handling and grasping device to run above the valve body, and the PLC system polls the photoelectric switch signals of the X-axis slide 9, the Y-axis slide 10, the Z-axis slide 11, and the rotating device 12 to check whether they reach the specified position. If not in the specified position, a check is prompted.
[0027] When the jaws 14 reach above the valve body, the PLC controls the Z-axis slide 11 to move towards the valve body, and the photoelectric switch feeds back the position signal to the PLC. When it reaches the sensing position, the Z-axis slide 11 stops. The cylinder of the jaws 14 pushes the movable plate of the jaws 14 to move towards the valve body, and the magnetic switch feeds back the signal to the PLC. When it reaches the sensing position, it indicates that the valve body has been clamped, and the cylinder stops moving.
[0028] After clamping the valve body, the PLC system controls the jaw 14 of the handling and grasping device to run to the position of the test bench fixture. The PLC system polls the photoelectric switch signals of the X-axis slide 9, Y-axis slide 10, Z-axis slide 11, and the rotating device 12 to check if they reach the specified positions. If not at the specified positions, a check is prompted.
[0029] When the jaw 14 reaches the position of the test bench fixture, the PLC controls the rotating device 12 to flip 90°, making the valve body mounting surface face the direction of the fixture. When the jaw 14 reaches the position of the test bench fixture, the PLC controls the Y-axis slide 10 to move towards the fixture, and the photoelectric switch feeds back the position signal to the PLC. When it reaches the sensing position, the Y-axis slide 10 stops, indicating that the valve body mounting surface has been fitted with the fixture.
[0030] The fixture cylinder moves, and the magnetic switch feeds back the position signal to the PLC. When it reaches the sensing position, the cylinder stops moving, indicating that the valve body has been clamped. The jaw 14 cylinder retracts, the movable plate of the jaw 14 releases the valve body, and the magnetic switch feeds back the signal to the PLC. When it reaches the sensing position, it indicates that the valve body has been released, and the cylinder stops moving.
[0031] The PLC system controls the jaw 14 of the handling and grasping device to run to the origin position. The PLC system polls the photoelectric switch signals of the X-axis slide 9, Y-axis slide 10, Z-axis slide 11, and the rotating device 12 to check if they reach the specified positions. If not at the specified positions, a check is prompted.
[0032] When it is necessary to remove the valve body from the fixture and place it back on the assembly line 15, the control method is as follows.
[0033] The PLC control system judges whether the tray carrying the valve body on the assembly line 15 is in place according to the feedback signal of the travel switch of the assembly line 15. If not in place, subsequent actions are stopped.
[0034] After being in place, the PLC system polls the magnetic switches on the first automatic door 6, second automatic door 7, third automatic door 8, fixture, and cylinder to check if the first automatic door 6 is in the closed position and if the second automatic door 7 and third automatic door 8 are in the open positions. If not in the corresponding positions, a check is prompted.
[0035] The PLC system controls the jaw of the handling and grasping device to run to the position of the test bench fixture. The PLC system polls the photoelectric switch signals of the X-axis slide 9, Y-axis slide 10, Z-axis slide 11, and the rotating device to check if they reach the specified positions. If not at the specified positions, a check is prompted.
[0036] The jaw 14 reaches the position of the fixture on the test bench. The PLC controls the Y-axis slide 10 to move towards the fixture. The photoelectric switch feeds back the position signal to the PLC. When it reaches the sensing position, the Y-axis slide 10 stops, indicating that the jaw 14 has reached the valve body position. The cylinder of the jaw 14 pushes the movable plate of the jaw 14 to move towards the valve body. The magnetic switch feeds back the signal to the PLC. When it reaches the sensing position, it indicates that the valve body has been clamped and the cylinder stops moving. The cylinder of the test bench fixture moves. The magnetic switch feeds back the position signal to the PLC. When it reaches the sensing position, the cylinder stops moving, indicating that the fixture has released the valve body.
[0037] The PLC system controls the jaw 14 of the handling and grasping device to run to the position of the tray on the production line 15. The PLC system polls the photoelectric switch signals of the X-axis slide 9, Y-axis slide 10, Z-axis slide 11, and the rotating device to check whether it reaches the specified position. If it is not in the specified position, a prompt for inspection is given.
[0038] The jaw 14 reaches above the tray. The PLC controls the Z-axis slide 11 to move towards the tray. The photoelectric switch feeds back the position signal to the PLC. When it reaches the sensing position, the Z-axis slide 11 stops. The cylinder of the jaw 14 retracts, and the movable plate of the jaw 14 releases the valve body. The magnetic switch feeds back the signal to the PLC. When it reaches the sensing position, it indicates that the valve body has been released and the cylinder stops moving. The PLC system controls the jaw 14 of the handling and grasping device to run to the origin position. The PLC system polls the photoelectric switch signals of the X-axis slide 9, Y-axis slide 10, Z-axis slide 11, and the rotating device to check whether it reaches the specified position. If it is not in the specified position, a prompt for inspection is given.
[0039] At the origin position, the PLC controls the first automatic door 6 to open, and the second automatic door 7 and the third automatic door 8 to close. The magnetic switches of the first automatic door 6, the second automatic door 7, and the third automatic door 8 feed back signals to the PLC system to judge whether they are in place. If they are not in place, a prompt for inspection is given.
