Description

Technical Field

[0001] The utility model relates to the technical field of gas valve flaw detection, in particular to a gas valve flaw detection device for an internal combustion engine. Background Art

[0002] The internal combustion engine valve is an important component of the internal combustion engine, mainly used to control the inlet and outlet of the combustion chamber. The working performance of the valve directly affects the operating efficiency and life of the internal combustion engine. Due to the harsh working environment of the internal combustion engine, the valve is prone to wear and breakage during long-term operation. Therefore, regular flaw detection inspections are required to ensure the normal operation of the internal combustion engine. The flaw detection device can quickly and accurately detect cracks and defects on the surface of the valve, thereby improving the detection efficiency.

[0003] After searching, the publication number CN207457137U disclosed an internal combustion engine valve flaw detection device. A tailstock is fixed on one end of the base, a ejector is installed on the tailstock, a PLC controller is installed on the other end of the base, a stepper motor is installed in the housing of the PLC controller, a chuck is provided at the end of the stepper motor, a horizontal moving motor is installed on the upper part of the base plane, a slide rail is connected to one end of the horizontal moving motor, an ultrasonic probe clamping mechanism is installed on the slide rail, a pulse eddy current probe clamping mechanism is installed on the inner side of the ejector, and probes are installed on the ultrasonic probe clamping mechanism and the pulse eddy current probe clamping mechanism. The utility model uses pulse eddy current to detect the internal combustion engine valve and the transition section of the valve stem and valve seat, which can overcome the defects of a single pulse eddy current detection method and complete the comprehensive detection of the internal combustion engine valve as a whole. The invention is suitable for use as an internal combustion engine valve flaw detection device.

[0025] Specifically, first, the air valve is placed above the storage table 11. The storage table 11 is designed to facilitate the placement and operation of the air valve and ensure that it can be stably maintained in the correct position in subsequent steps. Next, the output end of the motor 2 inside the workbench 1 drives the rotating plate 3 to rotate, thereby driving the rotation of the rotating plate 3, so that the rotating plate 3 drives one end of the connecting rod 4 to move. The function of the connecting rod 4 is to connect the rotating plate 3 and the slide plate 5, and convert the rotational power of the rotating plate 3 into the linear motion of the slide plate 5. The slide plate 5 slides inside the workbench 1, and the movement of the slide plate 5 drives the support 6 to slide on the upper surface of the workbench 1. The function of the support 6 is to support and fix the air valve. The support 6 is against both ends of the air valve to ensure that the air valve will not shift during operation. Then, the output end of the motor 2 7 drives the rotating disk 8 to rotate inside the support 6. The rotation of the rotating disk 8 drives the sliding rod 9 to slide in the arc-shaped slide groove. One end of the sliding rod 9 drives the clamping plate 10 to fix the two ends of the air valve, so that the air valve is firmly fixed on the support 6, thereby achieving the fixation of the air valve.

[0027] Specifically, first, the electric slide rail 13 inside the workbench 1 drives the bracket 14 and the flaw detection head 23 to move, thereby moving the flaw detection head 23 to the position where flaw detection is required. In this process, the bracket 14 plays a role of stability and support, ensuring that the flaw detection head 23 maintains a good working condition during the movement, and realizes precise control of the flaw detection head 23. Then, by rotating the rotating sleeve 16, the connecting rod 17 drives the screw 18 to rotate inside the mounting block 15, so that the sliding sleeve 19 slides on the outer wall of the screw 18, thereby driving one end of the push rod 20 to move, and then through the movement of the push rod 20, the other end of the push rod 20 moves, thereby driving the clamping block 21 to slide inside the mounting block 15 and the mounting sleeve 22, making the disassembly and assembly of the flaw detection head 23 more convenient and quick, and reducing the maintenance cost.

[0028] Working principle: When the internal combustion engine valve flaw detection device is needed, the valve is first placed on the storage table 11, and then the output end of the motor 2 inside the workbench 1 drives the rotating plate 3 to rotate, so that one end of the connecting rod 4 is driven to move through the two ends of the rotating plate 3, and then the other end of the connecting rod 4 drives the slide plate 5 to slide inside the workbench 1, and then the movement of the slide plate 5 drives the support 6 to slide on the upper surface of the workbench 1, so that the support 6 is against the two ends of the valve, and then the output end of the motor 2 7 drives the rotating disk 8 to rotate inside the support 6, so that the sliding rod 9 slides in the arc-shaped slide groove inside the rotating disk 8, and then the sliding rod 9 One end of the clamping plate 10 drives the two ends of the air valve to fix the air valve, thereby achieving the effect of fixing the air valve, and then the electric slide rail 13 inside the workbench 1 drives the bracket 14 and the flaw detection head 23 to move, thereby driving the flaw detection head 23 to perform flaw detection, and then by rotating the rotating sleeve 16, the screw rod 18 is driven to rotate inside the mounting block 15 through the connecting rod 17, so that the sliding sleeve 19 slides on the outer wall of the screw rod 18, and then the push rod 20 is moved to move one end of the push rod 20, so that the other end of the push rod 20 drives the block 21 to slide inside the mounting block 15 and the mounting sleeve 22, and then the flaw detection head 23 is conveniently disassembled and assembled through the mounting sleeve 22.
