[0028] Among them, the displacement sensor 10 and the damper 12 are both existing technologies, and their components and operating principles are public technologies, so no detailed explanation is given here.
[0029] Working principle: First, when the device is in normal use, a magnet 3 is set on the inner surface wall of the sleeve body 1. When the two connecting shaft bodies 4 are inserted into the sleeve body 1 one above and one below, the magnet 3 can attract the two connecting shaft bodies 4, which can ensure the close fit between the sleeve body 1 and the connecting shaft body 4, reducing the positioning error caused by gap or looseness. Secondly, the outer walls of the two connecting shaft bodies 4 are each provided with two threaded holes 2 5, and the outer walls of the two connecting rings 6 are threadedly connected to the inner surface walls of the two threaded holes 1 2. The connecting rings 6 can be replaced according to the specific size of the connecting shaft body 4, so that the sleeve body 1 can use connecting shaft bodies 4 of different sizes, making it flexible. Higher, at the same time, the outer walls of the two connecting rings 6 are provided with two threaded holes 3 7, and the four threaded holes 2 5 are aligned with the four threaded holes 3 7. At this time, four screws 1 8 are inserted into the threaded holes 2 5 and the threaded holes 3 7 at the same time to connect and fix the sleeve body 1 to the connecting shaft body 4, making the sleeve body 1 more stable to use. Secondly, the outer walls of the two connecting rings 6 are provided with square holes 9, and the inner walls of the two square holes 9 are provided with displacement sensors 10. Through the two displacement sensors 10, the motion state of the positioning straight sleeve can be continuously monitored, including parameters such as displacement speed and acceleration, which helps to timely detect abnormal conditions of the sleeve body 1 during operation, such as jamming, jumping, etc., for the equipment The maintenance and care of the machine is provided. At the same time, two springs 11 are fixedly installed on the inner surface walls of the two connecting rings 6. The four springs 11 are fixedly connected to the four clamping plates 13, and the four clamping plates 13 are fitted with the connecting shaft body 4. During the operation of the machine, the connecting shaft body 4 will be impacted and vibrated, making the connecting shaft body 4 easily overstressed and damaged. The spring 11 can absorb these impacts and vibrations, reduce the impact and damage risks of the connecting shaft body 4 during the force process, and make the machine work more smoothly. Secondly, the outer wall of the sleeve body 1 is movable with a rubber pad 15, and the outer wall of the rubber pad 15 is movable with a protective shell 17. The rubber pad 15 and the protective shell 17 The cooperation can reduce the direct contact between the positioning straight sleeve and other components, thereby reducing the risk of wear and scratches on the surface of the sleeve body 1, and the rubber pad 15 can reduce some of the impact on the sleeve body 1 to a certain extent, which helps to maintain the smoothness and precision of the sleeve body 1 and extend its service life. At the same time, the protective shell 17 and the rubber pad 15 are connected and fixed to the sleeve body 1 by inserting two screws 19 into the threaded hole 6 18, the threaded hole 5 16 and the threaded hole 4 14 at the same time. When the protective shell 17 and the rubber pad 15 need to be replaced, the screw 2 19 is directly unscrewed, and the protective shell 17 and the rubber pad 15 can be replaced more conveniently.
