Detailed ways

The following embodiments will further describe the utility model in conjunction with the accompanying drawings.

As shown in Figure 1-4, the cycloidal gear locator includes a T-slot guide rail 1 and a cycloidal gear 2. There are two T-slot guide rails 1 in a cross shape, and the cycloidal gear 2 includes a semicircular pin. 3 and the clamping platen 4, the cycloidal gear 2 is fixed on the T-shaped groove guide rail 1 by the semicircular pin 3, and the straight side of the semicircular pin 3 is parallel to the side of the clamping platen 4.

Described T-slot guide rail 1 comprises screw mandrel 5 with handle, long guide rail 6 and short guide rail 7, and described long guide rail 6 is provided with large slide block 8 and first small slide block 9, and described short guide rail 7 is provided with The second small slide block 10 and the third small slide block 11 are arranged, and the large slide block 8, the first small slide block 9, the second small slide block 10 and the third small slide block 11 are provided with threaded holes and handles. Screw mandrel 5 cooperates.

The first small slider 9 is provided with a short pin 12, the second small slider 10 is provided with a first long pin 13, and the third small slider 11 is provided with a second long pin 14.

The T-shaped groove guide rail 1 is provided with a scale.

The utility model utilizes the outer contour of the cycloidal gear 2 rough-machined as the positioning reference for finishing machining, and three stop pins fixed on the slider fix the tooth groove of the cycloidal gear 2, and the slider can slide in the T-shaped groove guide rail 1 , There is a scale on the T-slot guide rail 1. By adjusting the position of the stop pin, it can meet the positioning of the cycloid gear 2 of different specifications; On the same circle, the scale line on the guide rail indicates the position of the slider. After the positioning of the cycloid gear 2 is completed, the semicircular pin 3 is used to transfer the cycloid gear 2 to the machine tool fixture. The center of the semicircular pin 3 determines the reference of the cycloid gear 2. Point, the straight edge of the semicircular pin 3 defines the orientation of the cycloidal gear 2.

The locator is shown in Figure 1 and Figure 2. The positioning device has a long guide rail 6 and a short guide rail 7. The first small slider 9 and the large slider 8 slide in the long guide rail 6, driving the short stop pin 12 and the first long stop pin 13 and the second long pin 14 move longitudinally; the second small slider 10 and the third small slider 11 slide in the short guide rail 7, driving the first long pin 13 and the second long pin 14 to move laterally; the large slider 8. There are threaded holes on the first small slider 9, the second small slider 10 and the third small slider 11, which cooperate with the screw mandrel 5 with the handle to form a screw mechanism.

There is a scale engraved on the T-slot guide rail 1, the handle rotates one circle, and the slider advances one step, so that the three retaining pins are located on the same circumference, and the first long retaining pin 13 and the second long retaining pin 14 are symmetrically distributed on the long guide rail 6 sides.

The assembly of the locator and the machine tool fixture is shown in Figure 3 and Figure 4. The cycloidal gear 2 is fixed on the machine tool fixture, and the semicircular pin 3 passes through the semicircular hole of the clamping plate 4 and the semicircular hole of the machine tool fixture to find the correct direction for the locator. The reference point of the cycloidal gear 2 is concentric with the semicircular pin 3, and the straight side B of the semicircular pin 3 is parallel to the side B of the clamping plate 4.

It can be seen from Fig. 4 that the short stop pin 12, the first long stop pin 13 and the second long stop pin 14 are respectively tangent to the tooth groove of the cycloidal gear 2, and the three points are located on the same circumference, and the three points locate the cycloidal gear 2.
