The following is the overall operation of the above embodiment:
firstly, a workpiece to be reamed is placed at a proper position on the left side of a base 1, and the workpiece is positioned among a U-shaped slide bar 21, a clamping head 22 and a sliding clamping bar 26;
when the reamer body 2 is in operation, the reamer body 2 is started and slides downwards along the sliding rail, the guide rod 32 is driven to move downwards simultaneously when the reamer body slides downwards, the arc-shaped part of the guide groove 31 is extruded and slowly slides into the linear part when the guide rod 32 moves downwards, the rotating column 28 is driven to rotate clockwise in the process, the supporting rod 29 and the laser pen 30 are driven to rotate clockwise by the rotating column 28, so that the reamer body 2 is avoided, meanwhile, the pressing frame 3 and the first magnet 4 are driven to move downwards simultaneously when the reamer body 2 slides downwards along the sliding rail, when the reamer body 2 moves for a period of time and is in contact with a workpiece, the first magnet 4 and the second magnet 9 are in contact according to the principle of opposite attraction, the pressing frame 3 presses the pressing rod 8 downwards and enables the pressing rod 8 to slide downwards along the guide column 10, when the return spring 11 is compressed and the compression bar 8 slides downwards, the screw nut 7 is driven to move downwards, so that the ball screw 5 rotates anticlockwise, then the pawl 16 is driven to rotate anticlockwise, at the moment, the pawl 16 is propped against the ratchet wheel 15, so that the ratchet wheel 15 is driven to rotate anticlockwise through the pawl 16, the rotating disc 6 is driven to rotate anticlockwise, at the moment, if the feeding speed of the reaming machine body 2 is normal, the speed of the screw nut 7 is pressed downwards, the rotating speed of the ball screw 5 is normal, the rotating speed of the rotating disc 6 is normal under the driving of the ratchet wheel 15 and the pawl 16, the centrifugal force generated when the rotating disc 6 rotates is normal, at the moment, the knocking post 13 cannot slide in the sliding groove 12 or the sliding distance is smaller, so that the knocking rod 14 cannot be knocked when the rotating disc 6 drives the knocking post 13 to rotate, the workpiece can be normally processed;
when the reaming body 2 is in quick contact with a workpiece and the feeding speed is too high, the speed of the reaming body 2 for pressing down the screw nut 7 is increased, so that the downward sliding speed of the screw nut 7 is increased, the ball screw 5 is increased in rotation, then the rotating disc 6 is increased in rotation under the driving of the ratchet wheel 15 and the pawl 16, the centrifugal force is increased, the outward sliding distance of the knocking post 13 in the sliding groove 12 is increased, when the rotating disc 6 drives the knocking post 13 to rotate, the knocking post 13 contacts the knocking rod 14, and under the extrusion of the knocking rod 14, the knocking post 13 slides inwards in the sliding groove 12 for a certain distance, then slides outwards again for a certain distance under the action of the centrifugal force, so that when the rotating disc 6 drives the knocking post 13 to rotate, the knocking post 13 is continuously knocked down, and an alarm sound is emitted, and when a worker hears the sound, reducing the feed speed of the reamer body 2 or stopping feeding, overhauling the internal parts of the reamer body 2, preventing the machining quality of the parts from being affected when the machining of the parts is carried out, and when the feed speed of the reamer body 2 is reduced, because the sliding groove 12 and the knocking post 13 are obliquely arranged, the knocking post 13 slides into the sliding groove 12 again under the influence of gravity, so that the worker does not give out alarm when contacting the knocking rod 14, the feed speed is too fast, thereby reducing the feed speed or stopping the reamer body 2 to inspect the inside of the reamer body, avoiding that the feed speed is too fast, a great amount of heat is generated when the drill drills ream the workpieces, leading the temperature of the drill bits to be rapidly increased, exceeding the allowable temperature of materials and the drill bits, leading the cutting amount to be large, leading the cutting chips to be difficult to be discharged when reaming, thereby affecting the hole wall quality, and overheating the drill bits, and deforming or sintering hard alloy characters, the abrasion is too fast, and the service life is reduced;
further, when the reaming body 2 drives the down-pressing frame 3 to move downwards, the down-pressing frame 3 presses down the screw nut 7 and drives the pressing rod 8 to slide downwards along the guide post 10, the pressing rod 8 slides downwards to drive the spring telescopic rod 20 to move downwards, so as to push the sliding post 18 to slide inwards in the fixed barrel 17, when the sliding post 18 slides downwards, the left end of the connecting rod 19 is pulled to move downwards and rotate, so that the connecting rod 19 moves in an arc shape, so that the right end of the connecting rod 19 pushes the U-shaped slide rod 21 to slide rightwards along the base 1, when the U-shaped slide rod 21 slides rightwards, the clamping head 22 is pulled to move rightwards, so as to clamp the right side of the clamping head 22 and the left side and the right side of the base 1, and when the U-shaped slide rod 21 slides rightwards, the linkage post 23 is driven to slide rightwards along the base 1, so as to drive the two connecting blocks 24 to move rightwards, the connecting block 24 is further rotated and pushes the right ends of the two swinging rods 25 to rotate in opposite directions, so that the left ends of the swinging rods 25 are rotated and mutually close, the two linkage blocks 27 are driven to mutually close and rotate between the two swinging rods 25, when the linkage blocks 27 mutually close, the sliding clamping rods 26 are pushed to slide along the left ends of the base 1 and mutually close, so that the front and back sides of a workpiece are clamped, the fixing effect of the workpiece during machining is improved through clamping the front and back sides and the left and right sides of the workpiece, the shaking of the workpiece is reduced during reaming, the finish degree of reaming caused by shaking of the workpiece is reduced, the quality of the workpiece after reaming is further improved, when the workpiece is clamped by the clamping head 22 and the sliding clamping rod 26, the U-shaped sliding rod 21 cannot slide rightwards under the limit of the workpiece, and at the moment, if the reaming machine body 2 continues to slide downwards to ream the workpiece, the screw nut 7 is continuously pressed down by the pressing frame 3, the screw nut 7 drives the pressing rod 8 to slide downwards, and when the pressing rod 8 continuously slides downwards, the spring telescopic rod 20 is compressed;
