In the working of a grinding head component of a deep hole internal grinder, because the depth of a hole to be ground is generally more than 1000mm, the grinding tool is longer than that of the internal grinder, and the grinding tool contacts a machined part to generate a reaction force, and the continuous rotation of a main shaft is greatly influenced, in order to overcome the cantilever lever arm caused by the length of the grinding tool, the main shaft is divided into a front part and a rear part in the prior art, and the main shaft at the front end is connected with the grinding tool for machining the part; the length of the rear end main shaft is set to be 70% of that of the front end main shaft, and the rear end main shaft is connected with a belt pulley and is used for transmitting power brought by a motor rotating shaft and overcoming a cantilever lever arm; the front and rear end main shafts are connected through a coupling.
In order to ensure that the rear end main shaft can stably transmit the power brought by the motor rotating shaft and overcome the arm of force of the cantilever lever, as shown in figure 4, a shaft sleeve is sleeved on the outer side of the rear end main shaft in the prior art, and the rear end main shaft is rotatably connected with the shaft sleeve through a bearing; the main body of the rear end main shaft is arranged in the shaft sleeve, the end part of the rear end main shaft extends out of the shaft sleeve to be in a conical surface shape, and the belt pulley is fixed on the conical surface; the belt pulley rotates to drive the rear end main shaft to rotate, and the rear end main shaft rotates to drive the grinding tool fixed on the front end main shaft to rotate. The grinding head seat fixing seat is matched with the outer part of the shaft sleeve and is fixed on the deep hole inner circle grinding machine tool through the grinding head seat fixing seat, so that the grinding head assembly can move through a workbench of the machine tool and rotate the grinding part. Although the vibration generated by partial main shaft can be reduced by arranging the shaft sleeve on the outer side of the main shaft, when the parts are ground, the rear end main shaft is connected with the belt pulley which is connected with the motor rotating shaft belt pulley in a belt transmission mode, when the motor rotating shaft rotates to drive the belt pulley fixed on the rear end main shaft, the vibration generated by the main shaft is greatly influenced, the shaft sleeve is in clearance fit in the grinding head seat fixing seat, and the main shaft vibrates relative to the shaft sleeve, so that the vibration of the shaft sleeve is caused; and because the grinding tool is long, a cantilever lever arm is generated, and the vibration of the main shaft is amplified through a lever effect, the grinding tool cannot accurately grind the inner circle of a part, and the accuracy of the inner circle grinding is affected.
