Abstract
The invention discloses a stepped shaft punching clamp which comprises a first cylinder, a second cylinder, screw clamping mechanisms, a cover plate and fasteners. The second cylinder is disposed in the first cylinder. The upper surface of the second cylinder is lower than that of the first cylinder. A first round hole is reserved at the center of the lower end face of the first cylinder. A plurality sets of threaded holes are symmetrically reserved on the first cylinder and the second cylinder. The screw clamping mechanisms for clamping stepped shaft are connected to the threaded holes. The cover plate is disposed on the second cylinder. The cover plate is connected with the second cylinder through the fasteners. A second round hole which is as large as the first round hole and located on the same axis with the first round hole is reserved on the cover plate. The stepped shaft punching clamp is convenient to operate, high in machining efficiency, and suitable for batch machining. The stepped shafts can be well fixed, precision and straightness of machined through holes is guaranteed, and the requirements of production and machining are satisfied.

Technical solution of the present invention is achieved in that a kind of multidiameter perforating clamp, comprises the first cylindrical shell, the second cylindrical shell, screw rod clamp mechanism, cover plate and securing member; Be provided with the second cylindrical shell in described the first cylindrical shell; Described the second cylindrical shell upper surface is lower than the upper surface of the first cylindrical shell; The center of described the first cylindrical shell lower surface has the first circular hole; Symmetry has many group screwed holes on described the first cylindrical shell and the second cylindrical shell; Be connected with in the described screwed hole for the screw rod clamp mechanism that clamps multidiameter; Described the second cylindrical shell is provided with cover plate; Described cover plate links to each other with the second cylindrical shell by securing member; Have identically with the first circular hole size on the described cover plate, and be positioned at the second circular hole on the same axis.
Preferably, described screw rod clamp mechanism comprises screw rod, paw and knob; Described screw rod is arranged in the screwed hole; The inner end of the described screw rod paw that has been rotatably connected; Described paw is arcuation; The outer end of described screw rod is provided with knob.
Preferably, described screwed hole is symmetrical two groups.
Preferably, described cover plate is rounded.
Preferably, described cover plate upper surface is mutually concordant with the upper surface of the first cylindrical shell.
Preferably, the external diameter of described cover plate is identical with the internal diameter of the first cylindrical shell.
Preferably, described securing member is arranged with two.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
