Described LC hole and right centre bore are High Precision Central hole.
Described multiple left set screw is arranged in the periphery of described left positioning disk equably, and radially turn is to adjust described Super Long-axles center, described multiple right set screw is arranged in the periphery of described right positioning disk equably, and radially turn to adjust described location-plate center.
Described described location-plate is connected with described Super Long-axles by multiple bolts that axially screw along described Super Long-axles.
Compare with the mode of traditional top direct clamping Super Long-axles, the beneficial effects of the utility model are: Super Long-axles is located and is clamped on grinding machine top by described frock clamp, not only the positioning precision of Super Long-axles can be improved in the High Precision Central hole on this frock clamp, and this frock clamp can adjust again the center of Super Long-axles easily, thereby the center of workpiece and the error of lathe pivot are greatly reduced.The utlity model has advantage simple in structure, that positioning precision is high and adjustability is good.
Accompanying drawing explanation
Fig. 1 is the structure diagram of Super Long-axles.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is working state schematic representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the frock clamp for the grinding of Super Long-axles class part outer described in the utility model is described in further detail, but can not limits protection domain of the present utility model with this.
Refer to Fig. 2, diagram is arranged on Super Long-axles 5 for the frock clamp of Super Long-axles class part outer grinding, forms an assembly with Super Long-axles 5, and these Super Long-axles 5 centers have axle center hole.The described frock clamp for the grinding of Super Long-axles class part outer comprises left positioning disk 1, left locating shaft 3, right positioning disk 8, location-plate 6 and right locating shaft 9.
Described left positioning disk 1 is arranged on the left end of Super Long-axles 5, it is connected with described Super Long-axles 5 left ends by multiple left set screw 2, the center in this left positioning disk 1 outside is provided with LC hole 11, with with the top location that is connected of grinding machine, this LC hole 11 is High Precision Central hole, has higher repetitive positioning accuracy through Precision Machining.Described multiple left set screw 2 is arranged in the periphery of described left positioning disk 1 equably, and can be along the radially turn of Super Long-axles 5, to adjust the center of described Super Long-axles 5.Described left locating shaft 3 is fixed on the center of described left positioning disk 1 inner side, and stretches in the axle center hole of Super Long-axles 5 left ends, with the left end centralized positioning of described Super Long-axles 5.
