865 and the sliding block 862 to move together with the third rotating shaft 864 and 863, then, the transmission belt 863 can drive the connection block 869 to move, because the third rotation shaft 865 and the third support frame 862 are tightly fitted, the transmission belt 863 cannot easily transmit, then the connection block 869 moves along with the transmission belt 863, and the support rod 71 is pulled by the extension spring 860 to move, so that the support rod 71 is driven to move in the centrifugal direction, then the second support plate 711 can move in the centrifugal direction, so that the second support plate 711 can drive the first telescopic assembly 74 and the second telescopic assembly 75 to move, and the first positioning arc plate 72 and the second positioning arc plate 73 are driven to move in the centrifugal direction by the first telescopic assembly 74 and the second telescopic assembly 75, and then because the hole of the valve block is circular, the first positioning arc plate 72 can be abutted against the inner wall of the hole, and then the second support plate 711 can continue to move in the centrifugal direction, because the position is not clamped, the first positioning arc plate 72 moves backwards, and the second positioning arc plates 73 on two sides are driven to move forwards and towards two sides of the second positioning arc plate 73 by the first telescopic assembly 74 and the second telescopic assembly 75, so that the first positioning arc plate 72 and the second positioning arc plates 73 completely abut against the inner wall of the hole to position the hole, and then the disc 70 is pressed downwards to press the position of the disc 70 on the magnet rod 84 and be attracted by the magnet rod 84, that is, the disc 70 is pressed on the magnet rod 84 each time the valve block is positioned, but because the size of the hole on the valve block is different, half of the distance of the movement exists during the movement of the disc 70 on the magnet rod 84, and when the disc is not pressed on the magnet rod 84, the first positioning arc plate 72 and the second positioning arc plates 73 abut against the inner wall of the hole, therefore, the first positioning arc plate 72 and the second positioning arc plate 73 cannot move, that is, the supporting rod 71 cannot move, at this time, the disc 70 continues to move downwards, so that the second sliding block 82 continues to move centrifugally, that is, the second supporting rack 861 continues to move, but the position of the supporting rod 71 does not change, that is, the position of the third rack 867 does not change, so that the second supporting rack 861 moves to drive the third rotating shaft 865 to move through the third supporting rack 862, the connecting block 869 pulls the supporting rod 71 through the extension spring 860, and the supporting rod 71 does not move, so as to avoid that the first positioning arc plate 72 and the second positioning arc plate 73 apply excessive force to the hole, that is, the extension spring 860 is extended by too long length, at this time, the second gear 866 moves on the third rack 867, that is, the second gear 866 rotates clockwise, and then drives the transmission belt 863 to transmit, then the transmission belt 863 drives the connecting block 869 to move towards the direction of the supporting rod 71, then the second sliding block 82 moves centrifugally, the connecting block 869 moves centripetally, the position of the connecting block 869 can be kept unchanged, and therefore, the stretched length of the stretching spring 860 is ensured, and the hole of the valve block is successfully positioned, then the first driving part 51 drives the clamp seat 5 to move to the position of the first supporting plate 52, the valve block is kept at the current position and fixed on the clamp seat 5, then the first driving part 51 drives the clamp seat 5 to move in and out of the grinding knife 3 in a reciprocating manner, so that the valve block is ground, and the second oil pipe 9 sprays lubricating oil to the inside of the hole to lubricate the hole, so that the grinding effect is further ensured;

when the valve block is ground, the clamp seat 5 drives the valve block to enter and exit the grinding cutter 3, when the valve block exits the grinding cutter 3, the valve block enters the second oil pipe 9, then the oil tank 6 adds lubricating oil into the second oil pipe 9 and blows the lubricating oil out of the oil injection hole 93, then the oil filling position where the third oil pipe 41 faces is the grinding cutter 3, the oil filling position where the first oil pipe 4 faces is the outside of the valve block, then the first oil pipe 4 can enable the lubricating oil to permeate into the hole to be ground along a plurality of holes on the valve block when the oil is filled in, then the third oil pipe 41 keeps no waste on the grinding cutter 3 all the time and ensures the grinding effect of the grinding cutter 3, then the second oil pipe 9 adds oil into the hole processed by the valve block, thereby better ensuring that the oil in the hole is enough oil pipe when the oil pipe is ground, the grinding effect is not poor due to the small amount of oil, then the second oil injection is performed in the second oil pipe 9, the waste materials adhered to the inner part of the hole can be sprayed down, the waste materials are better discharged outwards, the processing effect and the product quality are further improved, the driving rod 34 drives the displacement knife 33 to move outwards gradually, so that the displacement knife 33 is slightly lower than the grinding knife 3 at first and then pushed out of the grinding knife 3, and the holes with different sizes are ground;
meanwhile, the disc 70 presses the fifth support plate 831 downwards, so that the second link 83 is driven to move by the fifth support plate 831, and then the second link 83 drives the third slide block 853 to slide on the fifth guide rod 852, but since the control assembly 87 blocks the position of the third slide block 853, the third slide block 853 cannot slide on the fifth guide rod 852, so that the third slide block 853 drives the control assembly 87 to move, and the control assembly 87 drives the second slide block 82 to move; the control unit 87 controls the blocking position of the resistance unit 85, so that when a larger hole is needed to be positioned, that is, when the first positioning arc plate 72 and the second positioning arc plate 73 are not yet abutted against the inner wall of the hole after the disc 70 is moved onto the magnet rod 84, the control unit 87 will not block the third sliding block 853, so that the third sliding block 853 will slide on the fifth guiding rod 852 under the action of the second compression spring 854, thereby increasing the moving stroke of the third sliding block 853, then the fifth supporting plate 831 and the disc 70 are connected in a sliding manner, and the shafts hinged by the second connecting rod 83 and the fifth supporting plate 831 are connected together, so that the second driving unit 53 moves to drive the fifth supporting plate 831 to slide on the disc 70 through the second connecting rod 83, and then the shafts on the blocking slot 31 of the positioning unit 7 will drive the supporting rod 71 to move, thereby increasing the moving stroke of the second support plate 711, and thus increasing the moving stroke of the first positioning arc plate 72 and the second positioning arc plate 73, so that the range of positioning the holes is increased;
meanwhile, the positioning component 86 operates to drive the fourth gear 881 to move, then the fourth gear 881 drives the fourth rack 882 to move downwards for a certain distance, then the fifth rack 883 slides, so that the fourth rack 882 and the fifth rack 883 can only move downwards for a small distance without being disengaged from the fourth gear 881, that is, the connecting frame 871 is driven to move for a small distance, therefore, the control component 87 is driven to move when the positioning component 86 operates, otherwise, the control component 87 is not driven to move;
then, before the disc 70 moves to the position of the magnet rod 84, the positioning of the hole is realized, then, the positioning strength of the first positioning arc plate 72 and the second positioning arc plate 73 is kept through the positioning component 86, and cannot be damaged, then, when the disc 70 moves to the position of the magnet rod 84, the first positioning arc plate 72 and the second positioning arc plate 73 do not contact with the inner wall of the hole yet, at this time, the adaptation range is increased through the resistance component 85 and the control component 87, that is, in the first case, the positioning component 86 moves, the positioning strength is kept, the positioning component 86 moves, the connecting frame 871 is driven by the switch component 88 to move downwards, then the connecting frame 871 moves under the guidance of the fourth telescopic rod 872, the connecting frame 871 drives the driving plate 874 to move through the third connecting rod 873, then the driving plate 874 drives the moving frame 878 to move through the fourth connecting rod 875, then the moving frame 878 moves towards both sides under the effect of the third telescopic rod, so as to drive the two electronic control doors 879 to move, so that the outer electronic control door 879 moves to a position where the outer electronic control door 879 does not cooperate with the third sliding block 853, the inner electronic control door 879 cooperates with the third sliding block 853, the inner electronic control door 879 is firstly fixed, so that the position of the third sliding block 853 is completely fixed, so that the normal positioning is realized, and then in the second situation, the positioning component 86 does not move, so that the position of the moving frame 878 does not change, the position of the electronic control door 879 does not change, and then the outer electronic control door 879 cooperates with the third sliding block 853, so that the inner side does not cooperate, and then when the disc 70 moves onto the magnet rod 84, the switch is touched, the outer electronic control door 879 is opened, and then the outer electronic control door 879 does not fix the third sliding block 853, so that the third sliding block 853 can move under the action of the second compression spring 854 to drive the supporting rod 71 to increase the range of movement, thereby increasing the size of the hole to be positioned.
