The second gear assembly 420 can be detached from the first gear assembly 220, that is, the engagement connection between the second gear assembly 420 and the first gear assembly 220 can be detached, and when the angle of the base 230 needs to be adjusted, the second gear assembly 420 is engaged with the first gear assembly 220; when the base 230 does not need to be angularly adjusted, the meshed connection of the second gear assembly 420 and the first gear assembly 220 is released. The accuracy of finish milling of the target workpiece is improved by controlling the meshing connection state of the second gear assembly 420 and the first gear assembly 220 and the connection state between the base 230 and the frame body 100 through the lifting assembly 300.
Further, another embodiment of the present invention also provides a rotary milling machine table, wherein the rotating assembly 400 further comprises: a knob 430 for driving the second transmission rod 410 to rotate; the knob 430 is coupled to the second transmission rod 410.
In the present embodiment, the knob 430 is used to drive the second transmission rod 410 to rotate, so that the user can adjust the rotation of the second transmission rod 410 to better adjust the rotation of the base 230. Wherein, the side of the knob 430 may be provided with a plurality of raised grains to increase the friction force of the knob 430, so that the rotation of the knob 430 is more easily controlled.
Further, another embodiment of the present invention also provides a rotary milling machine table, wherein the rotating assembly 400 further comprises a second dial 440; the second dial 440 is disposed around a side of the second transmission rod 410.
In this embodiment, the second dial 440 is disposed around the side of the second transmission rod 410, so that a user can more easily obtain the rotation angle of the base 230 according to the rotation of the second transmission rod 410, thereby improving the control capability of the rotation angle of the base 230, enabling the rotation of the base 230 to be more accurate, and improving the precision of the finish milling of a target workpiece. Since the first gear assembly 220 and the second gear assembly 420 are engaged with each other, the scale precision of the second scale disk 440 can be set according to the number of gears of the first gear assembly 220, for example, the number of gears is 360, then the second gear assembly 420 drives the first gear assembly 220 to rotate one gear per revolution, then the base 230 correspondingly rotates 1 degree, and then the scale precision of the second scale disk 440 is 1 degree; therefore, the scale accuracy of the second dial 440 may be affected by the number of gears provided to the first gear assembly 220. The scale range of the second dial 440 is correspondingly set according to the number of gears of the second gear assembly 420, for example, the number of gears of the second gear assembly 420 is N, and the rotation angle of each gear of the first gear assembly 220 corresponding to the base 230 is M degrees, so the scale range of the second dial 440 is 0 degrees to N × M degrees, that is, the second transmission rod 410 drives the second dial 440 to rotate one turn to rotate the base 230 by N × M degrees, and the rotation angle of the base 230 can be known according to the rotation angle of the second dial 440.
Meanwhile, the scale range of the second dial 440 may be set to 0 degree to 360 degrees, and the scale precision of the second dial 440 may be set according to the number of gears of the second gear assembly 420, for example, the number of gears is 90, so that each time the second gear assembly 420 rotates by one gear, the second transmission rod 410 correspondingly rotates by 4 degrees, and then the scale precision of the second dial 440 is 4 degrees; therefore, the scale accuracy of the second dial 440 can be affected by setting the number of gears of the second gear assembly 420. And the rotation angle of the base 230 can be obtained according to the ratio of the number of gears of the second gear assembly 420 to the number of gears of the first gear assembly 220 and the rotation angle of the second dial 440, for example, the ratio of the number of gears of the first gear assembly 220 to the number of gears of the second gear assembly 420 is 2:1, the rotation angle of the second dial 440 is 8 degrees, and the rotation angle of the base 230 is 4 degrees.
Further, another embodiment of the present invention also provides a rotary milling machine table, wherein the number of gears of the first gear assembly 220 is greater than the number of gears of the second gear assembly 420.
In this embodiment, the number of gears of the first gear assembly 220 is greater than the number of gears of the second gear assembly 420, so that the second gear assembly 420 completes one rotation, but the first gear assembly 220 does not complete one rotation, i.e. the total meshing area of the first gear assembly 220 is greater than that of the second gear assembly 420; when a user applies an external force to the second transmission rod 410, the external force applied each time generally only can make the second transmission rod 410 rotate one circle at most, and then the second transmission rod 410 can drive the second gear assembly 420 to rotate one circle, but the second gear assembly 420 can only drive the first gear assembly 220 to rotate a distance less than one circle, that is, the second gear assembly 420 rotates 360 degrees, and the rotation angle of the first gear assembly 220 is less than 360 degrees. Meanwhile, since the fine adjustment operation of the position of the component by the user is generally difficult to be performed, the fine adjustment of the position can be performed only by adjusting the component for a plurality of times, and therefore, the difference between the rotation angle of the first gear assembly 220 and the rotation angle of the second gear assembly 420 is large by setting the number of the gears of the first gear assembly 220 to be greater than the number of the gears of the second gear assembly 420, so that the fine adjustment operation of the rotation angles of the first gear assembly 220 and the base 230 through the second transmission rod 410 is performed, and the rotation efficiency of the base 230 is improved. Wherein the number of gears of the first gear assembly 220 may be four times the number of gears of the second gear assembly 420 such that the rotation of the second driving lever 410 by 360 degrees only rotates the base 230 by 90 degrees.
