Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 4, the disc milling jig includes: the rotary table comprises a first rotary table 1 and a second rotary table, wherein the first rotary table is provided with a first abutting surface 2, a positioning cone 3 is arranged on the first abutting surface 2, and the positioning cone 3 can be inserted into a workpiece 12; the anti-tilting block 13 is arranged on the first abutting surface 2 and is positioned on the side of the positioning cone 3, an abutting column is movably arranged on the anti-tilting block 13, and the anti-tilting block 13 can be inserted into the workpiece 12 and abuts against the inner surface of the workpiece 12; and the second rotating disc 5 is positioned on the side of the first rotating disc 1 and can be close to or far away from the first rotating disc 1, the second rotating disc 5 is provided with a second abutting surface 6, and when the second rotating disc 5 is close to the first rotating disc 1, the second abutting surface 6 can abut against the end surface of the workpiece 12.

The end face of a workpiece 12 abuts against the first abutting face 2, the positioning cone 3 is inserted into the workpiece 12 to perform datum positioning on the workpiece 12 at the moment, the second abutting face 6 abuts against the other end face of the workpiece 12, namely the first rotary table 1 and the second rotary table 5 mutually clamp the workpiece 12, the anti-tilting block 13 is inserted into the workpiece 12 at the moment, the anti-tilting block 13 is movably inserted with an abutting column which abuts against the inner surface of the workpiece 12, when the workpiece 12 rotates, the abutting column can provide axial supporting force for the workpiece 12, when the workpiece 12 is milled, the axial force borne by the workpiece 12 can be offset by the axial force provided by the abutting column, so that the workpiece 12 can be prevented from being deviated under the milling force, and the milling precision is ensured.

Prevent having seted up shifting chute 7 in the piece 13, be provided with in the shifting chute 7 and remove spring 8, support to lean on the post activity to insert to shifting chute 7 in and support to lean on post one end to support and lean on in removing spring 8.

In the process that anti-tilt block 13 inserted into work piece 12, lean on the post to receive the extrusion force and drive and remove spring 8 and move backward, conveniently prevent that tilt block 13 inserts in work piece 12, after preventing tilt block 13 and inserting in work piece 12, lean on the post to receive the resilience force that removes spring 8, and then lean on the post and can lean on the internal surface that leans on in work piece 12 always.

The first rotary table 1 is provided with a first rotating shaft 9, the second rotary table 5 is provided with a second rotating shaft 10, and the first rotating shaft 9 and the second rotating shaft 10 rotate synchronously.

During milling, the first rotating shaft 9 and the second rotating shaft 10 rotate synchronously, namely the first abutting surface 2 and the second abutting surface 6 rotate simultaneously, so that the first abutting surface 2 and the second abutting surface 6 can rotate at the same angular speed, the second abutting surface 6 cannot deviate from the workpiece 12 in an angle mode, and the second abutting surface 6 is prevented from sliding friction with the workpiece 12 to damage the workpiece 12.

The end of the first turntable 1 is provided with a plurality of fool-proof blocks 11, the fool-proof blocks 11 are inserted into the workpiece 12, when the workpiece 12 abuts against the first abutting surface 2, the fool-proof blocks 11 can be inserted into the workpiece 12, and the workpiece 12 is convenient to place and position.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein will be apparent to those skilled in the art without departing from the scope and spirit of the invention as defined in the accompanying claims.
