Abstract
The utility model provides a kind of multi-knife-head cutter, and comprise the handle of a knife of band centre bore, be inserted with connecting pin in the centre bore of handle of a knife, described connecting pin axial end portion has cutter head screwed hole, and screwed hole has been threaded connection screw thread process cutter head or cutting-blade head.Connecting pin radially outer edge has cutter head groove.The utility model can install at least two cutter heads on a cutter, different cutter heads can be selected to process during processing different workpieces.If the cutter head that cutter is installed is all undesirable, directly changes cutter head and meet processing request, and whole cutter need not be changed, improve production efficiency, saved cost.
Description
Technical field
The utility model relates to cutting tool field, specifically a kind of multi-knife-head cutter.
Background technology
Cutting tool is the instrument for machining in machine-building.Cutter can be divided into five classes by the form of workpiece machining surface: processing cutting tool for surface, aperture knife tool, threading tool, cutting off tool, gear cutting tool.In actual production, staff, according to the type of part to be processed, selects the cutter be suitable for process.When part to be processed is not add man-hour according to classification, need workman ceaselessly to change cutter, production efficiency is low.
Utility model content
The utility model, in order to solve the problem of prior art, provides a kind of multi-knife-head cutter, can install at least two cutter heads, do not need to change cutter frequently, improve production efficiency, and be convenient for changing cutter head on a cutter.
The utility model comprises the handle of a knife of band centre bore, and be inserted with connecting pin in the centre bore of handle of a knife, described connecting pin axial end portion has cutter head screwed hole, connecting pin radially outer edge has cutter head groove.
Further improvement, described cutter head screwed hole has been threaded connection screw thread process cutter head or cutting-blade head.
Further improvement, described cutter head groove is connected with Surface Machining cutter head or screw thread process cutter head or Gear Processing cutter head by securing member.
The utility model beneficial effect is:
1, on a cutter, at least two cutter heads can be installed, during processing different workpieces, different cutter heads can be selected to process.
If the cutter head that 2 cutters are installed is all undesirable, directly changes cutter head and meet processing request, and whole cutter need not be changed, improve production efficiency, saved cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, comprise the handle of a knife 1 of band centre bore 2, be inserted with connecting pin 3 in the centre bore 2 of handle of a knife 1, described connecting pin 3 axial end portion has cutter head screwed hole 4 to the utility model structure, and cutter head screwed hole 4 has been threaded connection screw thread process cutter head or cutting-blade head.Connecting pin 3 radially outer edge has cutter head groove 3, and cutter head groove 3 is connected with Surface Machining cutter head or screw thread process cutter head or Gear Processing cutter head by securing member.
When processing different workpieces, corresponding cutter head is selected to process.If the cutter head that cutter is installed is all undesirable, corresponding cutter head can be changed to meet process requirements.
The utility model embody rule approach is a lot; the above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
