As shown in fig. 1, the present embodiment provides a hard steel internal grinding fixture, which includes a positioning ring 5, a bolt 2, a pressing ring 1, and a pressing screw 3; the positioning ring 5 is provided with a large through hole and a small through hole, a step structure is formed at the joint of the large through hole and the small through hole, a plurality of magnetic steels are placed on the step structure, and each magnetic steel forms a magnetic steel ring.
The pressing ring 1 is fixed with the positioning ring 5 through the bolt 2, and the magnetic steel ring is pressed in the positioning ring 5 through the pressing screw 3 by the pressing ring 1. The number of the bolts 2 is four, the number of the magnetic steels is ten, the number of the compression screws 3 is ten, each magnetic steel is compressed by one compression screw 3, and the radius of a ring formed by the compression screws 3 is smaller than that of a ring formed by the bolts 2.
The utility model creates the following advantages or beneficial effects:
1. the problem that the inner circular arc (discontinuous revolution surface) can be ground upwards and inwards is solved.
2. The problems that the medium-speed wire cannot meet the requirements on product precision and quality and the slow-speed wire can only be processed by a single piece are solved.
3. The tool has the advantages of simple structure, low manufacturing cost and convenient clamping and dismounting, greatly shortens the processing time, saves the production cost, and is beneficial to small, medium and large batch production of parts.
By adopting the technical schemes, the utility model has the advantages of simple design, easy manufacture and convenient use. The clamp consists of a positioning ring 5, a pressing ring 1, a pressing screw 3 and a standard component. Ten magnetic steels form a ring, the ring is arranged in a tooling positioning ring 5, the ring is pressed by a pressing ring 1, and the locking screw is used for locking, so that ten pieces of steel can be used for grinding inner holes together.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
