7. The operational use method of the intelligent polishing apparatus for mechanical manufacturing according to claims 1-6, characterized by comprising the steps of:

firstly, starting equipment and inputting a processing program;

secondly, clamping the left end of a cylinder (4) to be polished by a triangular chuck (3), and enabling a sliding bottom block (20) and a back plate (21) to move along a sliding rail (5) by contraction of a third hydraulic cylinder (29), so that a first roller (27) and a second roller (28) in an auxiliary clamping assembly are respectively in rolling contact with the outer circular surface and the right end surface of the cylinder (4) to assist in clamping;

thirdly, when the control panel (30) controls the spindle in the spindle box (2) to rotate so as to drive the triangular chuck (3) and the cylinder (4) to rotate, the first roller (27) and the second roller (28) additionally apply supporting force and left-hand pressure to the end of the cylinder (4), so that the cylinder (4) is clamped more stably and reliably, and the safety is improved;

fourthly, the distance between the upper ends of the front rocker (27) and the lower ends of the rear rocker (27) is changed by stretching and retracting the second hydraulic cylinder (25) and driving the front rocker (22) and the rear rocker (22) to rock by using the connecting rod (23), so that the cylinders (4) with different outer diameters are adapted;

fifthly, a grinding roller (17) is driven to rotate at a high speed through a second motor (16) and a rotating shaft (14), a first motor (7) rotates back and forth and drives a sliding seat (6) and a mounting seat (12) to move back and forth along a sliding rail (5) through a screw rod (8) and a ball nut (9), so that the grinding roller (17) and a sleeve (13) enter and exit the inner cavity of the cylinder (4) back and forth and contact with the bottom wall of the inner cavity to grind the inner wall of the inner cavity (because the cylinder (4) also rotates, the inner wall of the whole inner cavity of the cylinder (4) can be ground), the mounting seat (12) is driven to lift along a guide post (11) through a first hydraulic cylinder (10), and the grinding roller (17) is lifted to adapt to cylinders (4);

sixthly, the emulsion is flushed to the grinding roller (17) through the electromagnetic control valve (18) and the universal adjusting pipe (19), and when the grinding roller (17) grinds the inner hole wall of the cylinder (4), dust and flying chips are prevented from being raised and the temperature is prevented from being too high.
