The existing double-center mechanism is influenced by the structure of the existing double-center mechanism, and in order to clamp a center to-be-machined part, the to-be-machined part needs to be lengthened, so that the waste amount of raw materials of the to-be-machined part is large, and the cost of the raw materials is not easy to reduce; in addition, the existing double-center mechanism has larger volume and is easy to influence the processing.

SUMMERY OF THE UTILITY MODEL

In view of this, an object of the present invention is to provide a dual-tip mechanism for aluminum alloy processing, which can shorten the length of workpiece material, reduce the material cost, occupy a small space, and allow more space for selecting processing tools during processing.

In order to achieve the above purpose, the utility model provides a following technical scheme:

a double-centre mechanism for processing aluminum alloy comprises a centre body, a positioning pin and a locking bolt, wherein the centre body is provided with a pin hole and a bolt hole, the pin hole is arranged in a mode that the axis of the pin hole deviates from the central axis of the centre body, and the bolt hole arranged along the radial direction of the centre body is communicated with the pin hole; the positioning pin is inserted in the pin hole, and the locking bolt is inserted in the bolt hole and is pressed against or inserted on the positioning pin.

Furthermore, the locking device also comprises a locking block, and the locking bolt is pressed or inserted on the locating pin through the locking block.

Further, the axis of pinhole is parallel with the central axis of top body.

Further, the axis of the bolt hole is perpendicular to the axis of the pin hole.

The beneficial effects of the utility model reside in that:

the double-tip mechanism can be manufactured by itself, and is easy to manufacture and low in cost. When the mechanism is adopted to process a product which needs to be processed by a double-center processing method, the length of the workpiece raw material can be shortened, and the raw material cost is reduced. Because the length of the workpiece is reduced, the relative strength during processing is improved, and the quality precision of the workpiece processing can be further improved. Meanwhile, the device occupies small space, and more space can be provided for selecting processing tools during processing, thereby being beneficial to improving the processing efficiency.
