There are three chuck claw positioning grooves distributed at an angle of 120° along the through hole to the periphery of the disk. The positioning card is connected with the chuck claws which slide synchronously along the positioning slots of the chuck claws on the chuck positioning card.

The utility model is further characterized in that:

The tie rod group rotates along the axis of the block group, and the tie rod group is a U-shaped structure with one end open.

The fast clamping tool for gear shaper processing ring gear has the following characteristics:

1) Use the components of the waste lathe—the three-jaw chuck combined with the pallet, which has a simple structure and is easy to operate, and can quickly install and align the workpiece.

2) In the original processing, it is necessary to align the inner and outer circles and end faces of the workpiece for each different part, and the alignment speed is slow and time-consuming. After the improvement, the three-jaw chuck of the lathe is used, and only the three-jaw chuck is aligned. Yes, when reloading the workpiece (ring gear), the ring gear can be clamped and aligned through the self-centering of the three-jaw chuck. The ring gear can be quickly fixed, and it is very convenient to clamp the ring gear.

3) It is suitable for the processing of ring gears with various diameters. For batch parts, the speed of clamping and aligning is increased, the time for clamping and aligning is reduced, the labor intensity of workers is reduced, the work efficiency is improved, and the cost is reduced.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 2 , it is a structural schematic diagram of the improved clamping tooling of the present invention. The clamping tooling includes the tray 2, and six spacer group positioning grooves that extend radially along the circumference of the tray 2 to the center of the tray 2. In the six spacer group positioning grooves, three of the spacer blocks are spaced apart from each other. The group positioning groove is provided with a block group 3 that can slide along the positioning groove. The block group 3 is provided with a tie rod group 4. The tie rod group 4 can rotate along the axis of the block group 3, and the tie rod group 4 is open at one end. U-shaped structure. A three-jaw chuck 5 is arranged on the tray 2 , and the three-jaw chuck 5 is fixed by three tie rod groups 4 . The three-jaw chuck 5 is a disc-shaped structure with a through hole in the center, and three chuck jaw positioning grooves 14 that are distributed at an angle of 120° are arranged along the through hole to the periphery of the disk, and each of the three chuck jaw positioning grooves 14 The port is provided with a chuck claw 13, and a chuck positioning card 15 is arranged along the chuck claw positioning groove 14, and each chuck claw 13 can slide synchronously along the chuck claw positioning groove 14 under the rotation of the chuck positioning card 15.

As shown in Figure 3, it is a schematic diagram of the utility model; the workpiece 1 can be clamped directly by the three-jaw chuck 5, and the workpiece 1 can be quickly clamped at any one of the three positions (120 angles to each other).
