Example 1

The structure and the method of use of the present invention will be described by taking the quarter processing of the structure such as the surface, the groove, and the hole shown in fig. 1 as an example.

As shown in fig. 2, an auxiliary processing device for processing a quartering structure on a cylinder includes: a tetrahedron 1 with a cylinder, a screw 3 and a pressing plate 2;

the tetrahedron 1 with the cylinder is of an integral structure, and the length of the cylinder is less than that of the part to be processed, so that the part is conveniently compressed; the diameter of the cylinder is smaller than the aperture of the part and is in clearance fit with the part, so that the coaxiality of the cylinder during processing is ensured; a threaded hole matched with the screw 3 is processed on the end surface of the cylinder;

when a tetrahedron is machined, the parallelism between the four surfaces and the axis of the front section cylinder and the perpendicularity between the four surfaces are strictly controlled, and the four surfaces are sequentially positioned to perform quartering indexing on the part; in the same way, for any graduation, it is only required to ensure that each plane is parallel to the axis of the part and the included angle between each plane is consistent with the graduation required by the part processing, for example, for the processing of the trisection surface of the part, it is only required to set the polyhedron to be triangular; for the processing of the part with the angle of 70 degrees, 40 degrees, 70 degrees, 40 degrees and graduation, the included angles among all the surfaces of the polyhedron are arranged to be 70 degrees, 40 degrees, 70 degrees and 40 degrees in sequence; namely, the N-surface body is matched with the N graduation required to be processed by the part;

the pressing plate 2 is used for pressing the part on the end surface of the cylinder through a screw 3;

preferably, in order not to influence the processing of the part, the pressure plate is arranged not to exceed the boundary of the part after being connected with the cylinder.

Furthermore, in order to increase the pre-tightening force of the parts, the pressing plate is made of high-strength steel, such as 45 hardened and tempered steel.

Further, in order to increase the pre-tightening force of the part, the pressing plate is set to be in a circular sheet structure, as shown in fig. 2.

As shown in fig. 3, the above device is used as follows:

the part 4 is sleeved on a cylinder at the front section of the tetrahedron, the part is compressed by a screw and a pressing plate, the tetrahedron provided with the part is placed on the table board of the machine tool, the position of the part is aligned, a positioning plate 6 is fixed on the table board of the machine tool, the rear end surface and the side surface of the tetrahedron are tightly attached to two vertical planes of the positioning plate, and the radial and axial position sizes of holes (surfaces and grooves) of the part 4 are limited by limiting the front, rear, left and right positions of the tetrahedron. The tetrahedron is pressed, a first hole (surface and groove) is machined by a machine tool spindle 5, and then the tetrahedron is turned over to machine a second hole, a third hole and a fourth hole (surface and groove) in sequence.
