Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments：
The utility model as shown in Figure 1, 2, 3, angle of eccentricity mechanism, including main spindle box slide plate 1 and head bearing 6, main shaft
Middle part sets shaft between case slide plate 1 and head bearing 6, and head bearing 6 is rotated by axle center of shaft, which includes worm screw 2 and match somebody with somebody
To worm sector, the worm screw 2 and shaft are perpendicular, and worm screw 2 is arranged in main spindle box slide plate 1 and 2 both ends of worm screw pass through axis
It holds 3 to be arranged on main spindle box slide plate 1 and stretch out main spindle box slide plate 1,2 both ends of worm screw are equipped with stripped nut 4, the worm sector
Be fixed on head bearing 6, the center of worm sector on the center line of shaft,
The junction of the head bearing 6 and main spindle box slide plate 1 is respectively equipped with angle scale 12 and pointer 13.
Be connected between main spindle box slide plate 1 and head bearing 6 by bolt, the bolt hole on head bearing 6 be arcuate socket, arc
The center of circle of the center camber line in hole is on shaft centerline.Pointer is arranged on main spindle box slide plate 1, and angle scale is arranged on head branch
On the edge of seat 6, angle scale cooperation adjacent with pointer determines the rotational angle of the opposite main spindle box slide plate 1 of head bearing 6.
Head bearing 6 and the edge protrusion of 1 contact position of main spindle box slide plate set dowel hole 14, main spindle box slide plate 1 and machine
The side that head bearing 6 contacts is equipped with the positioning spiro pit with dowel hole cooperation, and bottom sets threaded circular cone positioning pin and passes through
Dowel hole is simultaneously screwed into positioning spiro pit.2 both ends of worm screw are supported by taper roll bearing.
Numerical control groover equipped with angle of eccentricity mechanism, on the vertical lifting track which is arranged on, head bearing 6
Front end sets main spindle box 7, is milling cutter knife rest below main spindle box, the top of head bearing 6 sets motor.
Working method：The bolt that is connected with main spindle box slide plate of head bearing is unclamped first, removes circular cone positioning pin, using pulling
Power is transmitted to worm screw by hand, rotary worm one end, and power is transmitted on worm gear by worm screw by being engaged with worm gear, and worm gear rotates band
Motivation head bearing rotates；Head bearing rotational movement main spindle box rotary motion, so that knife rest rotates by a certain angle.Worm screw
Both ends are supported by taper roll bearing when rotated, and are locked at both ends by each two stripped nuts so that entire revolution
It is light freely.By rotating shaft support when head bearing rotates.When head bearing rotates, indicated according to pointer, rotate counterclockwise to 3 °
Or 3 ° are rotated clockwise to, the bolt that head bearing is connected with main spindle box slide plate is then tightened, installs circular cone positioning pin.
It is time saving and energy saving since the rotation of this angle of eccentricity mechanism is more convenient, and angled instruction, rotation is accurate, uses
Effect is good, therefore can be positioned by the use of the revolution as cutting on other lathes.
