Detailed Description

In order that those skilled in the art will better understand the present invention, the following technical scheme of the present invention will be further described with reference to the accompanying drawings and examples.

Example 1

As shown in fig. 1-5, a half-hole grinding device is provided, firstly, a processed workpiece is placed on the top surface of a placing platform 9, the processed workpiece and the placing platform 9 are fixed by friction force only, and other fixing devices such as a clamp or a screw are not required to be installed; the position of the part is adjusted, the position of the hole to be machined on the part corresponds to the position of the honing knife, the honing knife can be just inserted into the hole of the part to be machined after moving downwards, the whole machine is opened at the moment, firstly, the transmission device 4 drives all the grinding rod modules 5 to rotate, the grinding rod modules 5 drive all the honing knives 7 to transmit, and because the side surfaces of all the honing knives 7 are contacted with the side surfaces of the idler wheels 16, when all the honing knives 7 rotate in the same direction, the idler wheels 16 rotate reversely due to friction force, all the honing knives 7 and the idler wheels 16 in the middle keep the same angular velocity to rotate, and by controlling the machine, the gear box 3 moves up and down, and the gear box 3 drives all the honing knives 7 and the idler wheel modules 11 to move up and down until the honing knives 7 contact the hole to be machined, and then the side surfaces of the honing knives 7 finish the side surfaces of the hole; because these holes are liable to generate centripetal force during machining, all honing knives 7, the machined holes are pushed to the middle, so the machining precision is sometimes not achieved, in order to ensure the precision of these holes during finishing, idler wheels 16 are added in the middle of many honing knives 7, and if the precision is still not achieved, the size of idler wheels 16 is adjusted; the diameter of the idler wheel 16 is thickened, and the honing cutter 7 is outwards supported for a whole circle, so that the honing cutter 7 is prevented from inwards shrinking; the top of the idler wheel 16 is provided with a top first nut 14 and a top second nut 15, the top first nut 14 and the top second nut 15 are fixed in the original positions after being screwed, the top of the idler wheel 16 is provided with a fixing function, the bottom of the idler wheel 16 is provided with an adjusting sleeve 19, the bottom of the adjusting sleeve 19 is provided with a bottom nut 18, if the diameter of the idler wheel 16 is to be adjusted, the top of the idler wheel 16 is firstly fixed after the top first nut 14 and the top second nut 15 are screwed, then the bottom nut 18 is rotated, the bottom nut 18 pushes the adjusting sleeve 19 to move upwards, the idler wheel 16 is extruded after the adjusting sleeve 19 moves upwards, the idler wheel 16 is outwards deformed and expanded through a gap of the idler wheel spiral groove 17 after the idler wheel 16 is extruded, then the diameter of the idler wheel 16 is enlarged, and all honing knives 7 on the outer sides are supported, so that all holes are completely machined in machining, the precision is not required to be machined to a small extent because the honing knives 7 shrink inwards, and the final machining is not required.
