Description
Technical field
The utility model belongs to standard machinery processing technique field, is related to the inner bore of step of high-accuracy shaped aluminum alloy part
Position clamping tool.
Background technology
Since part base angle is undersized, local formed with cutter is interfered, and can not be machined in numerically-controlled machine tool, there are office
Portion is remaining, can not meet drawing requirement.But when using Special lathe clamp, since the design of part is complicated, the weight of clump weight
Amount and size are difficult to estimate, and clamping is difficult.Part is off-center during actual processing, and part is often overproof, precision and surface
Quality is difficult to meet the requirements.
The content of the invention
Goal of the invention：A kind of stepped hole positioning clamping tool is provided, for CNC milling machine, plain-milling machine, center lathe
Positioning clamps.
Technical solution：A kind of stepped hole positions clamping tool, including：
Mandrel (1) and taper screw (2), described mandrel (1) one end is equipped with step, cross recess, the heart is provided with the step
One end center that axis (1) is equipped with step is provided with threaded hole；Taper screw (2) head is equipped with external screw thread, and taper screw (2) afterbody is
Centrum；Taper screw (2) head is screwed onto in the threaded hole of mandrel (1) through mandrel (1) step, taper screw (2) afterbody vertebra
Body is stuck at mandrel (1) step, by the outside tensioner of step.
Beneficial effect：The mating surface of a kind of stepped hole positioning clamping tool of the utility model, taper screw and mandrel carries
Equal angular, promotes taper screw, and two conical surfaces press together, and mandrel top bar is swelled so as to fix workpiece, the frock
It can be applied to center lathe, numerically controlled lathe, CNC milling machine.
Brief description of the drawings
Fig. 1 is the utility model right view.
Fig. 2 is the utility model front view.
Fig. 3 is the utility model section view.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
A kind of stepped hole positions clamping tool, as shown in Figure 1, 2, 3, including：
Mandrel 1 and taper screw 2, described 1 one end of mandrel are equipped with step, cross recess are provided with the step, and mandrel 1 is equipped with
One end center of step is provided with threaded hole；2 head of taper screw is equipped with external screw thread, and 2 afterbody of taper screw is centrum；Taper screw
2 heads are screwed onto in the threaded hole of mandrel 1 through 1 step of mandrel, and 2 tail cone of taper screw is stuck at 1 step of mandrel, foundation
The mating surface of dilating principle and clearance fit principle, taper screw and mandrel carries equal angular, promotes taper screw, two cones
Face presses together, and mandrel top bar is swelled so as to fix workpiece.It is cylindrical for centering in centering mandrel during clamping, can be with
Reduce jerk value.The frock can be applied to center lathe, numerically controlled lathe, CNC milling machine.
