The rear end of described connecting plate (8) is vertical with riser (2) right side to be fixed, a threaded bolt spring lock pin (9) is housed in the installing hole of this connecting plate leading section, and the steel ball in this threaded bolt spring lock pin can snap in the bar shaped indexing trough (7b) on described index dial (7).
Before calibration, first horizonal base plate (1) is fixed on work top, and scroll chuck is by being located in being bolted on index dial in scroll chuck installing hole, and workpiece is clamped by scroll chuck.During calibration, rotate index dial (7), because the central angle between four bar shaped indexing troughs (7b) is known in advance, so just know the angle of rotation when the steel ball of threaded bolt spring lock pin (9) successively snaps in two different bar shaped indexing trough (7b), this rotational angle is exactly the sub-degree angle of workpiece.
Adopt above technical scheme, the angle of rotation is just known when the steel ball of threaded bolt spring lock pin (9) successively snaps in different two bar shaped indexing trough (7b) in the utility model, this rotational angle is exactly the sub-degree angle of workpiece, whole indexing operation process is clear, clear, simply, conveniently, not easily make mistakes, and calibration efficiency is high, thus the defect overcoming traditional dividing head operation inconvenience well, very easily make mistakes.
For the ease of being connected and fixed, screw (10) after described rotating shaft (5) rear end is coaxially connected with, rear pad (11) is pressed on the rear end face of a bearing (6) next by the head of this rear screw; Described rotating shaft (5) front end is coaxially connected with a front screw (12), this front screw is set with a front pad (13), and described index dial (7) is pressed between the step surface of this front pad and rotating shaft (5) leading section.
In order to be fixed on work top by horizonal base plate (1) easily, spy has a n shape groove at the left and right end face at horizonal base plate (1) rear portion.
Beneficial effect: the angle just knowing rotation when the steel ball of threaded bolt spring lock pin successively snaps in different two bar shaped indexing troughs in the utility model, this rotational angle is exactly the sub-degree angle of workpiece, whole indexing operation process is clear, clear, simply, conveniently, not easily make mistakes, and calibration efficiency is high, thus the defect overcoming traditional dividing head operation inconvenience well, very easily make mistakes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, 2, a kind of indexing means, this indexing means is formed primarily of horizonal base plate 1, riser 2, fairlead 3, screw 4, rotating shaft 5, bearing 6, index dial 7, connecting plate 8, connecting plate threaded bolt spring lock pin 9, rear screw 10, rear pad 11, front screw 12 and front pad 13.Wherein, the left and right end face at horizonal base plate 1 rear portion has a n shape groove, and this horizonal base plate 1 is by being fixed on being bolted on work top in these two n shape grooves.
