Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy to operate, indexing means of not easily makeing mistakes.
The technical solution of the utility model is as follows: a kind of indexing means, it is characterized in that: comprise horizonal base plate (1), rotating shaft (5) and connecting plate (8), wherein the front end of horizonal base plate (1) end face is installed with one piece of riser (2), a fairlead (3) is housed in the installing hole on riser, and this fairlead is fixedly connected with riser (2) by screw (4); The rear portion of described rotating shaft (5) is stretched in fairlead (3), insertion section is supported on fairlead (3) by two front and back bearing side by side (6), and rotating shaft (5) front portion is installed with an index dial (7); Described index dial (7) is circumferentially evenly equipped with scroll chuck installing hole (7a), the through bar shaped indexing trough (7b) in 4 front and back is circumferentially had at index dial periphery, the cross section of this bar shaped indexing trough is circular arc, and according to being counterclockwise divided into first, second and third and four bar shaped indexing troughs (7b) successively; Central angle between described first bar shaped indexing trough (7b) and second bar shaped indexing trough (7b) is 90 °, central angle between first bar shaped indexing trough (7b) and the 3rd bar shaped indexing trough (7b) is 120 °, and the central angle between the 3rd bar shaped indexing trough (7b) and the 4th bar shaped indexing trough (7b) is also 120 °;
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.
