[0044] The working principle of a hole depth inspection tool for machining cylinder sleeves of internal combustion engines provided by the utility model is as follows: when the utility model is in use, the cylinder sleeve to be inspected is placed between two opposite clamping plates 9. At this time, under the action of the tension springs 6 on both sides of the positioning plate 4, the tension springs 6 pull the handle 7 toward the positioning plate 4, and the handle 7 drives the connecting rod 8 to move toward the clamping plate 9, and the clamping plate 9 clamps the cylinder sleeve, and the first motor 2 is turned on, and the output shaft of the first motor 2 drives the inspection disk 3 to rotate. When the cylinder sleeve to be inspected moves to the bottom of the inspection rod 19, the second motor 10 is turned on, and the output shaft of the second motor 10 drives the threaded rod 12 on one side thereof to rotate. When the threaded rod 12 rotates, it drives the threaded tube 13 and the bearing 14 on its outer side to move together, and the bearing 14 drives the connecting plate 15 to move downward, and the connecting plate 15 drives the inspection tube 17 on one side thereof to move downward, and the inspection tube 1 7 and the detection rod 19 inside it move downward together. When the bottom of the detection rod 19 passes through the inner hole of the cylinder sleeve, the detection rod 19 stops moving downward, while the detection tube 17 continues to move downward. When the support plates 22 on both sides of the detection tube 17 touch the top of the cylinder sleeve, it stops moving downward. At this time, the laser detector 21 on the top of the detection tube 17 is turned on to detect the distance between the top of the detection tube 17 and the adjustment disk 18. Since the total length of the adjustment disk 18 and the detection rod 19 is known, the hole depth of the cylinder sleeve can be calculated; when the threaded rod 12 is rotating, the connecting plate 15 and the support rod 16 also move up and down accordingly. At this time, the positioning rod 30 moves up and down in the limiting hole 29, thereby limiting the detection tube 17 to avoid shaking of the detection tube 17 due to the shaking of the connecting plate 15, thereby ensuring the stability of the device during operation and providing a guarantee for the accuracy of the detection result.
