Problems solved by technology
After the bearing 3 is compressed, due to the friction force, it is difficult to remove the bearing 3 from the shaft after the compression nut 1 is loosened.
It is necessary to knock the bearing 3 or other complicated methods to remove the bearing 3, which may damage the main shaft body 4 due to knocking or uneven force, resulting in damage and waste of the workpiece, which is not conducive to cost control

Embodiment Construction
[0012] figure 2 Among them, the bearing 3 is installed on the main shaft body 4, the washer 2 is close to the bearing 3, and the compression nut 1 realizes the compression of the washer 2 through the thread on the corresponding position of the main shaft body 4, thereby compressing the bearing 3. Thread is arranged on the major diameter end of main shaft body 4 of bearing 3 one side, and dismounting nut 5 is contained on the thread of main shaft body 4 major diameter ends and is positioned at the side of main shaft bearing 3. The dismounting nut 5 fits with the bearing 3 on the corresponding thread of the main shaft body 4 . When the bearing 3 is damaged and needs to be removed, loosen the compression nut 1, take out the compression nut 1 and the washer 2, turn the removal nut 5 to push the bearing 3 until the bearing 3 is loose, so that there is no need to beat the main shaft bearing 3 to remove it Lower spindle bearing 3. The quantity of dismounting nut 5 is one or more.

The invention provides a milling head / boring head spindle. A bearing is mounted on a spindle body; threads are formed on the spindle body in positions on two sides of the bearing; a compression nut for compressing the bearing is mounted on the thread at the small-diameter end of the spindle body; and a dismounting nut for dismounting the bearing is mounted on the thread at the large-diameter end of the spindle body. When the bearing on the spindle body is damaged and needs to be dismounted, the dismounting nut is rotated and move along the thread on the spindle body to the small-diameter end of the spindle body to be propped against the bearing on the spindle until the bearing on the spindle is loosened, so that the stress is uniform, the dismounting is convenient, and the bearing on the spindle can be dismounted without the need of beating or using other complex methods. The milling head / boring head spindle provides convenience for dismounting the bearing and is convenient, quick and practical to use.
Description
technical field [0001] The invention relates to a milling head and a boring head spindle. Background technique [0002] The traditional milling head and boring head spindle are composed of a compression nut 1, a washer 2, a bearing 3, and a spindle body 4, such as figure 1 shown. Bearing 3 is contained on the main shaft body 4, washer 2 is close to bearing 3, and compression nut 1 realizes compression washer 2 by the screw thread on the corresponding position on the main shaft body 4, thereby compresses bearing 3. After the bearing 3 is compressed, due to the effect of friction force, after the compression nut 1 is loosened, the bearing 3 is difficult to take off from the shaft. It is necessary to beat the bearing 3 or other complicated methods to remove the bearing 3, so that the main shaft body 4 may be damaged due to knocking or uneven force, resulting in damage and waste of the workpiece, which is unfavorable for cost control.
