Abstract
The invention discloses an indexing device. A guiding sleeve is installed on a vertical plate. The rear of a rotating shaft is supported into the guiding sleeve through two bearings. An indexing plate is fixedly arranged in the front of the rotating shaft in a sleeving mode. Three-claw chuck installing holes are uniformly distributed in the indexing plate in the edge direction. Four strip-shaped indexing grooves are formed in the outer circle face of the indexing plate in the peripheral direction. The central angle between the first strip-shaped indexing groove and the second strip-shaped indexing groove is 90 degrees. The center angle between the first strip-shaped indexing groove and the third strip-shaped indexing groove is 120 degrees, and the center angle between the third strip-shaped indexing groove and the fourth strip-shaped indexing groove is 120 degrees. The rear end of a connecting plate is vertically fixed to the right end face of the vertical plate. A bolt spring lock pin with a thread is installed in an installing hole in the front end of the connecting plate. Steel balls of the bolt spring lock pin with the thread can be clamped into the strip-shaped indexing grooves in the indexing plate. According to the indexing device, when the steel balls of the bolt spring lock pin with the thread are clamped into the two different strip-shaped indexing grooves one after another, the rotating angle will be known, the rotating angle is the indexing angle of a work-piece, the whole indexing operation process is clear, simple and convenient, errors do not occur easily, and the indexing efficiency is high.

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 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, 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 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.
