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 calibration pits in the present invention, 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, indexing accuracy 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 invention;
Fig. 2 is the front view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, 2, a kind of indexing mechanism, this indexing mechanism 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.
