Description
Technical Field
The utility model belongs to the technical field of machining, concretely relates to it is top.
Background
When a cutter with a front angle is machined by a conventional machine tool, an apex of a dividing head is out of action because the apex can only be flatly topped by 0 degree, so that when machining is carried out, because the apex is not supported, great vibration can be generated during machining, the precision and the efficiency of parts are influenced, and a tool during machining is damaged.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a it is top, through setting up top in height-adjustable, the angle-adjustable angle rotating head, according to dividing head change angle, according to the length change center height of cutter to make the cutter have top support in the processing, increased work efficiency, increase the life-span of precision and instrument, the cost is reduced.
The utility model adopts the following technical scheme:
the top comprises a vertical plate, a bottom plate, an angle rotating head, a top body, an adjusting screw, a first tightening bolt, a second tightening bolt and a nut, wherein the vertical plate is vertically fixed above the bottom plate, vertical long holes are formed in the upper position and the lower position of the central axis of the vertical plate respectively, an angle rotating head is arranged on the front side of the vertical plate, the upper portion of the angle rotating head is connected with the long holes in the upper portion of the vertical plate through the first tightening bolt and the nut, an arc-shaped long hole is formed in the lower portion of the angle rotating head, the arc-shaped long hole in the lower portion of the angle rotating head is connected with the vertical long holes in the lower portion of the vertical plate through the second tightening bolt, the top body penetrating angle rotating head is located between the first tightening bolt and the second tightening bolt, a groove is formed in the tail portion of the.
Furthermore, the center also comprises an anti-rotation jackscrew, a groove is axially formed in the center, an anti-rotation jackscrew through hole is formed in the angle rotating head, and the anti-rotation jackscrew penetrates through the angle rotating head and is jacked in the axial groove of the center.
Furthermore, the bottom of the angle rotating head is arc-shaped, the radian of the bottom of the angle rotating head is consistent with that of an arc-shaped long hole below the bottom of the angle rotating head, and angle scales are marked at the bottom of the angle rotating head.
The utility model discloses an advantage and effect do:
because the angle difference of the positive and negative anterior angle of cutter and the difference of cutter length can make the dividing head raise the head or the central height behind the low head changes to some extent, the utility model designs an adjustable top, this section is top not only can be according to dividing head change angle, also can be according to the length change center height of cutter to make the cutter have top support in the processing, increased work efficiency, increase the life-span of precision and instrument, the cost is reduced.
