Detailed description of the invention
, be described in detail below to the quick replacement device of accompanying drawing 5 to a kind of numerical control machine tool clamp body of the present utility model with reference to Figure of description 1.
A quick replacement device for numerical control machine tool clamp body, comprises that numerically controlled machine 1, some covers are provided with clamp body 2 and the hydraulic cylinder 3 of fixture 23; On described numerically controlled machine 1, be provided with several inner circle taper holes 11, the numerically controlled machine of described inner circle taper hole 11 belows is provided with through hole 12, and the diameter of described through hole 12 is less than the diameter of inner circle taper hole 11 bottom surfaces and is communicated with inner circle taper hole; Described clamp body 2 bottoms are provided with the positioning table 21 equating with female cone hole number, are provided with the cone 22 matching with inner circle taper hole 11 on described positioning table 21; Described hydraulic cylinder 3 is arranged on numerically controlled machine 1 below and quantity equates with the quantity of inner circle taper hole, and the piston 31 of hydraulic cylinder 3 is arranged in through hole and matches with hole size; Described inner circle taper hole 11 and the tapering of cone 22 are Morse's taper.
As shown in Figure 1 to Figure 5, wherein, as preferred version, numerically controlled machine 1 described in the utility model is provided with three inner circle taper holes 11, described clamp body 2 bottoms are provided with three positioning tables 21, and the cone 22 on described three positioning tables is corresponding with the inner circle taper hole 11 on numerically controlled machine respectively; Described three conical bores 11 offer respectively through hole 12 below.
When installation, replacing fixture, directly by three inner circle taper holes 11 in three cones, the 22 pressing in numerical control machine workbench 1 of clamp body 2, and primer fluid cylinder pressure 3, its piston 31 is moved downward with piston rod in through hole, all sealed up and down due to three through holes in numerically controlled machine 1, form vacuum, the piston of hydraulic cylinder 3 moves downward and produces powerful pulling force.Because the cone 22 of clamp body 2 adopts Morse's taper with numerically controlled machine 3, stop the reciprocal movement of clamp body 2, add the powerful pulling force that hydraulic cylinder produces, can firmly clamp body 2 be fixed on numerical control table, NC table 1.In the time that needs unload clamp body 2, open hydraulic cylinder 3, piston is moved upward and clamp body 2 can be released to numerically controlled machine 1.
