Description of the drawings:
FIG. 1 is a schematic view of a compact clamping device according to the present invention;
Fig. 2 is a schematic view of the compact clamping device of the present invention for clamping a ring shaft.
The specific implementation mode is as follows:
The present invention will be further explained with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of the compact clamping device of the present invention. The device comprises a moving shaft 1 needing to be locked, a gland 2, a sliding plug 3, a clamping ring 4, a support sleeve 5, a sealing ring 6 and an oil inlet 7, wherein the gland 2, the sliding plug 3, the clamping ring 4, the support sleeve 5, the sealing ring 6 and the oil inlet 7 form a compact clamping device. As shown in fig. 1, a support sleeve 5 is combined with a moving shaft 1 to be locked, an oil inlet 7 is arranged on the support sleeve 5, the oil inlet 7 is communicated between a clamping ring 4 and a sliding plug 3, the clamping ring 4 is arranged in an inner hole of the support sleeve 5, and a deformation groove 8 is arranged on the clamping ring 4; the sliding plug 3 is arranged between the support sleeve 5 and the clamping ring 4, the sealing ring 6 is arranged on the clamping ring 4 and the sliding plug 3, the gland 2 can effectively restrict the axial moving range of the sliding plug 3 and the clamping ring 4, so that the clamping ring 4 and the moving shaft 1 are reliably attached after hydraulic oil is injected between the sliding plug 3 and the clamping ring 4, the clamping effect is achieved, and the moving shaft 1 needing to be locked is arranged in a hole of the clamping ring 4.
when in clamping, hydraulic oil is pumped into the oil inlet to enable the deformation groove 8 on the clamping ring 4 to elastically deform, so that the surface of the inner hole of the clamping ring 4 is attached to the moving shaft 1; when the clamping ring is loosened, the oil pressure is unloaded, the deformation groove 8 is elastically deformed and restored, and the clearance between the clamping ring 4 and the moving shaft 1 is recovered to keep a separated state.
Fig. 2 is a schematic view of the compact clamping device of the present invention for clamping a ring shaft. The device comprises a circular ring moving shaft 1 to be locked, a gland 2, a sliding plug 3, a clamping ring 4, a central supporting shaft 5, a sealing ring 6 and an oil inlet 7, wherein the gland 2, the sliding plug 3, the clamping ring 4, the central supporting shaft 5, the sealing ring 6 and the oil inlet 7 form a compact clamping device. As shown in figure 2, a supporting shaft 5 positioned in the center is combined with a circular ring moving shaft 1 to be locked, an oil inlet 7 is arranged on the supporting shaft 5, the oil inlet 7 is communicated between a clamping ring 4 and a sliding plug 3, the clamping ring 4 is arranged in the supporting shaft 5, a deformation groove 8 is arranged on the clamping ring 4, the sliding plug 3 is arranged between the supporting shaft 5 positioned in the center and the clamping ring 4, a sealing ring 6 is arranged on the clamping ring 4 and the sliding plug 3, and a gland 2 can effectively restrict the axial moving range of the sliding plug 3 and the clamping ring 4, so that the clamping ring 4 is reliably attached to the circular ring moving shaft 1 after hydraulic oil is injected between the sliding plug 3 and the clamping ring 4, and a clamping effect is achieved. When clamping, hydraulic oil is pumped in through the oil inlet to enable the deformation groove 8 on the clamping ring 4 to elastically deform, so that the surface of the clamping ring 4 is attached to the circular ring moving shaft 1; when the oil pressure is unloaded during loosening, the deformation groove 8 elastically deforms and recovers, and a clearance is recovered between the clamping ring 4 and the circular ring moving shaft 1 to keep a separation state.
Fig. 1 is a schematic structural view of the compact clamping device of the present invention disposed outside the movable shaft to be clamped. Namely, the moving shaft 1 to be locked is installed in the inner hole of the clamping ring 4. Fig. 2 is another application of the compact clamping device of the present invention, namely, the compact clamping device is arranged inside the circular motion shaft for clamping. When the axis of motion to be clamped is circular, the deformation groove 8 may be an annular groove. More than one deformation groove 8 can be arranged.
