Description

Technical Field

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

[0002] Internal combustion engine cylinder block flaw detection is extremely important. Common flaw detection methods include magnetic particle testing and ultrasonic testing, which can detect surface and internal defects of the cylinder block. Flaw detection can promptly discover hidden dangers such as cracks, ensure the safe operation of the internal combustion engine, and extend its service life. Regular flaw detection inspections help prevent failures and ensure stable and efficient operation of the equipment.

[0003] The existing flaw detection device is not convenient for moving the flaw detector during use, which means that the flaw detector can only detect a limited area around its fixed position. It is impossible to flexibly adjust the position to detect different parts. It is very likely to miss some key areas, resulting in the inability to fully detect possible defects in the cylinder body. Utility Model Content

[0004] The purpose of the utility model is to provide a cylinder body flaw detection device for an internal combustion engine cylinder, which solves the problem that the flaw detector is inconvenient to move during use of the existing flaw detection device by being provided with a detection mechanism.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a cylinder body flaw detection device for an internal combustion engine cylinder, comprising a detection platform, wherein the detection platform comprises a detection mechanism and a fixing mechanism.

[0007] The detection mechanism includes a moving component and a detection component. The moving component includes two support plates fixedly connected to the top of the detection platform, and the front side of the corresponding support plate is fixedly connected to motor 1. The output shaft of motor 1 is fixedly connected to a threaded rod through a shaft coupling. The rear end of the threaded rod passes through the two support plates and is rotatably connected to the two support plates. An internal thread block is threaded on the threaded rod, and a limiting rod is fixedly connected between the two support plates. The internal thread block is slidably connected to the limiting rod.

[0008] Furthermore, the detection component includes a hydraulic cylinder fixedly connected to the top of the internal thread block, the output shaft of the hydraulic cylinder passes through the internal thread block and is slidably connected to the internal thread block, and the output shaft of the hydraulic cylinder is fixedly connected to the mounting box.

[0009] Furthermore, the inner wall of the installation box is fixedly connected to motor 2, the output shaft of motor 2 is fixedly connected to shaft 1 through a coupling, the bottom end of shaft 1 extends to the outside of the installation box and is rotatably connected to the installation box, and the bottom end of shaft 1 is fixedly connected to a detector.

[0010] Furthermore, the fixing mechanism includes a motor three fixedly connected to the bottom of the detection platform, the output shaft of the motor three is fixedly connected to a worm through a coupling, and the worm is rotationally connected to the bottom of the detection platform.

[0011] Furthermore, two rotating shafts 2 are fixedly connected to the bottom of the detection platform, and the bottom ends of the two rotating shafts 2 are fixedly connected to worm wheels, and the two worm wheels are engaged with the worm.

[0012] Furthermore, two guide rods are fixedly connected to the bottom of the detection platform, two movable plates are slidably connected to the two guide rods, diamond blocks are fixedly connected to the two rotating shafts, and two connecting plates are hinged between the two diamond blocks and the two movable plates.

[0013] Furthermore, two slide grooves are provided on the top of the detection platform, the tops of the two movable plates extend to the top of the detection platform and are slidably connected to the corresponding slide grooves, and the tops of the two movable plates are fixedly connected to clamping blocks.

[0014] Furthermore, a plurality of slide grooves 2 are provided on the side where the two clamping blocks are close to each other, the inner walls of a plurality of slide grooves 2 are slidably connected with clamping rods, the ends of a plurality of clamping rods away from the corresponding inner bottom walls of the slide grooves 2 extend to the outside of the clamping block, and a spring is fixedly connected between a plurality of clamping rods and the corresponding inner bottom walls of the slide grooves 2.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up a detection mechanism, start motor one, and motor one drives the threaded rod to rotate. When the threaded rod rotates, it drives the internal thread block to move on the limit rod. When the internal thread block moves, it drives the hydraulic cylinder to move. Start the hydraulic cylinder, and the hydraulic cylinder drives motor two to move up and down through the mounting box, thereby driving shaft one and the detector to move up and down. Start motor two, and motor two drives shaft one to rotate. When shaft one rotates, it drives the detector to rotate. Through the detection mechanism, a larger cylinder detection area can be covered, the detection range is expanded, and a comprehensive detection of the entire cylinder is ensured to reduce potential defects. At the same time, according to the structural characteristics of the cylinder and the parts where defects may exist, the detector can be moved to a specific location for key detection, thereby improving the pertinence and efficiency of the detection. At the same time, it can be combined with other movements to achieve all-round detection of the cylinder and improve the detection capability of complex shape defects.

[0017] 2. By setting a fixing mechanism, start motor three, and motor three drives the worm to rotate. When the worm rotates, the rotating shaft two is driven to rotate through the worm gear. When the rotating shaft two rotates, the connecting plate is driven to move through the diamond block. When the connecting plate moves, it drives the movable plate to slide on the guide rod. When the movable plate moves, it drives the clamping block to move. At the same time, when the clamping block clamps and fixes the cylinder body, the clamping rod in contact with the cylinder body moves into the slide groove two, thereby causing the spring to contract. The fixing mechanism can make the cylinder body maintain a stable position during the detection process, avoiding the measurement accuracy of the detector due to shaking or movement, so that the detection probe of the detector can always detect the cylinder body at an accurate angle and distance, ensuring the reliability of the detection result, and avoiding the cylinder body and the detector from colliding during the detection process, thereby causing the cylinder body to move, and then causing the cylinder body and the detector to collide, resulting in damage to the cylinder body and the detector.
