by naked eyes, the stable rotation speed can be reached after waiting for several seconds generally, then the sliding head 2 is moved transversely, so that the sliding head 2 drives the polishing wheel 4 to contact with the workpiece, when the polishing wheel 4 contacts with the workpiece, the rotation speed of the polishing wheel 4 is reduced under the influence of friction, another important parameter needs to be known, that is, the pressure applied when contacting with the workpiece, the sliding head 2 drives the right-angle bracket 51 to drive the pushing bracket 58 to move together,

transversely through the stable maintenance of the movable bracket 581, reduce the occurrence of deviation, it is not necessary to make the contact 582 contact with the contact cylinder 67 in the initial stage of the sliding head 2 movement, because the polishing work can not be performed on the workpiece in the initial stage of the sliding head 2 movement, only after the sliding head 2 moves a certain distance, the polishing grinding wheel 4 can be made to contact with the workpiece, when the contact 582 is driven to move to contact with the contact cylinder 67, the contact cylinder 67 can drive the connection push plate 64 to drive the sliding cylinder 63 to move inside the movable fixed barrel 62, because the inside of the movable fixed barrel 62 is filled with the liquid 81, the movable fixed barrel 62 is completely covered by the sealing outer sleeve 66, so that the liquid 81 in the movable fixed barrel 62 can not flow out through the sliding groove on the upper side, through the arranged diversion angle 65, the connecting push plate 64 can be more stable when moving, and the moving resistance is reduced, when the sliding cylinder 63 moves, the sliding cylinder 63

to move through the connection of the semicircular hook 76 and the tension spring 77, the tail plate 74 can drive the telescopic rod 73 to move, the telescopic rod 73 can drive the movable ring 83 to move, but the right side of the movable ring 83 is provided with the limit support 86, the rotation blocking sheet 85 can be prevented from rotating around the rotating shaft 84 to the right side through the arranged limit support 86, so when the movable ring 83 moves to the left, under the condition that the liquid 81 has the resistance, the rotation blocking sheet 85 which can not rotate to the right can cause larger resistance, the movable ring 83 and the rotary baffle 85 are subjected to the resistance of the liquid 81 to move rightwards together, so that the telescopic rod 73 is driven to move rightwards, the telescopic rod 73 drives the tail plate 74 to move rightwards through the semicircular hook 76 and the tension spring 77, the elastic force generated by the tension spring 77 is detected by the tension sensor 75, the tension detected by the tension sensor 75 is influenced by the moving speed of the sliding machine head 2 to change, but the overall error is not too large, if the sliding machine head 2 is driven to move electrically, the error is smaller, when the tension sensor 75 detects that the tension change is within a preset range, the sliding machine head 2 is considered to move, when the sliding machine head 2 stops moving, the tension sensor 75 becomes an initial value within a short time, the specific principle is as follows, according to the principle, the sliding cylinder 63 suddenly stops moving leftwards, at this time, the tension spring 77 will drive the tail plate 74 to drive the telescopic rod 73 to move leftwards and return to the original position, when the telescopic rod 73 moves leftwards and drives the movable ring 83 to move leftwards and return to the original position, although the telescopic rod 73 moves leftwards and drives the movable ring 83 to move leftwards and return to the original position, the resistance of the liquid 81 will be received, but the moving stroke is short, so the stop can be fast, in the starting stage of the sliding cylinder 63 moving leftwards, according to the above principle, the telescopic rod 73 will move rightwards, the telescopic rod 73 will drive the pull rope hook 91 to move rightwards, before the pull rope hook 91 moves rightwards, the non-elastic pull rope 92 connected to the pull rope hook 91 will be perpendicular to the bottom position of the sliding cylinder 63, in the state that the non-elastic pull rope 92 is perpendicular, the non-elastic pull rope 92 will not apply a traction force to the movable block 93, but after the telescopic rod 73 will drive the pull rope hook 91 to move rightwards, the rope hook 91 will drive the top end of the non-elastic rope 92 to move rightwards, so that the non-elastic rope 92 is no longer in a vertical state, at this time, the non-elastic rope 92 will generate a pulling force on the movable block 93, the movable block 93 will move upwards against the elastic force of the second extension spring 94, the movable block 93 will drive the telescopic clamping strip 97 to move upwards, the telescopic clamping strip 97 will drive the friction head 98 to move upwards and separate from the smooth surface 99, it should be understood that, although the sliding cylinder 63 will move upwards to drive the friction head 98, at first, the length of the smooth surface 99 is enough to make the friction head 98 slide on the upper side of the smooth surface 99 during the starting stage, and the length of the smooth surface 99 will not cause the friction head 98 and the smooth surface 99 to move downwards due to the influence of the sliding friction force when the sliding cylinder 63 drives the friction head 98 to move transversely and before the friction head 98 is lifted upwards, so that the friction head 98 will not easily move downwards due to the sliding resistance of the sliding cylinder 9998 when the sliding cylinder 97 moves upwards, the sliding cylinder 9998 is in a stable state, at this time, the sliding cylinder 9998 will not easily move downwards, and the sliding cylinder 9998 will move downwards, when the sliding cylinder 92 is in a stable state, the sliding resistance of the sliding cylinder 991, the sliding cylinder 93 will not easily causes the sliding cylinder to move downwards, the sliding cylinder 93 to move downwards, the sliding cylinder 9963 to move downwards, and the sliding cylinder 93 to move downwards, at this time, the sliding cylinder 992 will move downwards, and the sliding cylinder 93 will move again, and the sliding resistance of the sliding cylinder 992 will not easily move downwards, when the sliding cylinder 992 will move downwards, the sliding cylinder 93 will move downwards, and the sliding cylinder 93 will move again, and the sliding cylinder 93 will move downwards, at this time, the sliding cylinder 93 will move again, and in the stable state, the sliding head 2 moves to a position where the sliding head contacts with the workpiece, although the position has a certain error, the stroke of the error is very short, the error of the stroke can be compensated by the telescopic stroke of the compression spring 584, the sliding head 2 is moved continuously to polish the workpiece, and the error is realized by compressing the compression spring 584, the elastic force generated by the compression of the compression spring 584 is detected by the pressure sensor 583, the pressure detected by the pressure sensor 583 is equivalent to the pressure applied to the workpiece by the polishing wheel 4, based on the determined pressure value, by the ratio of the original rotating speed after the idle stabilization of the polishing wheel 4 to the rotating speed after contacting with the workpiece, a value can be obtained, which on the premise that a determined pressure value is used as a basis, the larger the ratio of the rotating speed of the idle polishing wheel 4 to the rotating speed of the polishing wheel 4 at the polishing time is, the smaller the diameter of the polishing wheel 4 is represented, the smaller the ratio of the rotating speed of the idle polishing wheel 4 to the rotating speed of the polishing wheel 4 is represented, the larger the diameter of the polishing wheel 4 is obtained by the experimental data, and the specific polishing wheel diameter can be referred to the polishing wheel 4.
