FIG. 2 is a schematic cross-sectional view of FIG. 1;

the symbols in the drawings illustrate that:

centering base 1, hydro-cylinder 2, voussoir 3, movable block 4, clamping jaw 5, first inclined plane 6, second inclined plane 7, apron 8, leading-in piece 9, leading-in inclined plane 10.

Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a hydraulic centering fixture includes a fixture body, where the fixture body includes a centering base 1, an oil cylinder 2 fixedly disposed at the bottom 1 of the centering base, and two sets of clamping jaw assemblies disposed on the centering base 1, and in this embodiment, the oil cylinder 2 is an oil cylinder conventionally used in the prior art, so that detailed descriptions of the specific structure thereof are omitted;

specifically, the output end of the oil cylinder 2 penetrates through the centering base 1, the output end of the oil cylinder 2 is fixedly connected with a wedge block 3, two groups of clamping jaw assemblies are respectively and symmetrically arranged on two opposite sides of the wedge block 3, each clamping jaw assembly comprises a movable block 4 which is clamped on the centering base 1 in a sliding mode and a clamping jaw 5 which is fixedly arranged on the movable block 4, a first inclined surface 6 is arranged on one side surface, close to the wedge block 3, of the movable block 4, a second inclined surface 7 which is matched with the first inclined surface 6 is arranged on the wedge block 3 at a position corresponding to the first inclined surface 6, and the first inclined surface 6 and the second inclined surface 7 are mutually abutted in a sliding mode during installation;

a cover plate 8 is further arranged on the centering base 1 corresponding to the position above the wedge block 3, one end of the cover plate 8 is fixed to the top of the centering base 1, the other end of the cover plate 8 extends to a position between the movable block 4 and the clamping jaw 5, specifically, a gap is formed between the movable block 4 and the clamping jaw 5 and close to the wedge block 3, an extending end of the cover plate 8 extends into the gap, and gaps are also formed between the extending end of the cover plate 8 and the movable block 4 and between the cover plate 8 and the clamping jaw 5;
