Specific implementation mode
For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and attached drawing further
Explanation, the content that embodiment refers to not is restriction to the utility model.The utility model is carried out below in conjunction with attached drawing
Detailed description.
A kind of thermal shrinkage type gang tool of fast changeable cutter head provided by the utility model, including cutter head 1 and pyrocondensation
Handle of a knife 2, the cutter head 1 are equipped with the plug division 4 for being connect with heat-shrinkable knife handle 2, are opened up among the end of the heat-shrinkable knife handle 2
There is the chimeric clamping chamber 3 than 4 undersized of plug division, after heat-shrinkable knife handle 2 is expanded by heating, chimeric clamping chamber 3 expands, described
Plug division 4 can be easily inserted in chimeric clamping chamber 3, and after the cooling of heat-shrinkable knife handle 2, cutter head 1 is clamped and fixed in heat-shrinkable knife handle 2
On.Cutter head 1 made of mold compacting sintering is placed in the chimeric clamping heated by the utility model using the principle expanded with heat and contract with cold
In chamber 3, the radial load generated after 2 cooling meat of heat-shrinkable knife handle clamps cutter head 1；After cutter head 1 is worn, knife is needed replacing
When head, heat-shrinkable knife handle 2 need to be only placed into shrinkage apparatus and be heated, then cutter head 1 is pulled up, then change a new cutter head 1
It is combined into a new cutter, the utility model realizes the long-time service of Quick changing cutter 1 and heat-shrinkable knife handle 2, carries
The high usage time of heat-shrinkable knife handle 2, saves production cost.
In the present invention, the cutter head 1 is formed by mold compacting sintering, and plug division 4 is integrally formed with cutter head 1.
The cutter head 1 and plug division 4 are formed by mold compacting sintering, thus can machine-shaping reduced size cutter head 1, due to cutter head
1 replacement is easy to assembly, and the cutter head 1 of small size also can be steadily installed on heat-shrinkable knife handle 2, cutter head described in the utility model
1 sword diameter D >=1mm.Break the size limitations of conventional combination cutter, it is applied widely.1 mold molding sintering of cutter head at
Type, the forming cost by mold molding sintering are grinding machine molding 20% or so, the molding of relatively traditional grinding machine
Cutter head have larger cost advantage.
Further, the surrounding annular setting of the plug division 4 is there are four chimeric slot 5, the chimeric clamping chamber 3 it is interior
Wall protrusion is equipped with and the clamping convex ribs 6 of 5 shape adaptation of chimeric slot.Preferably, the chimeric slot 5 is set as straight type groove or oblique type
Slot.When the cutter head 1 is combined with the assembly of heat-shrinkable knife handle 2, clamping convex ribs 6, which are inserted into, to be fitted into slot 5, and 2 clamp precision of cutter head is high, turns round
Square is big, not will produce rotation and abjection phenomenon, has higher rigidity.The cutter head 1 uses hard alloy with heat-shrinkable knife handle 2
Material is made, and increases tool strength.
Further, the clamping convex ribs 6 have lead-in chamfered 7 in the end set close to chimeric 3 entrance of clamping chamber.It is logical
The setting lead-in chamfered 7 on clamping convex ribs 6 is crossed, chimeric slot 5 can be guided to coordinate with clamping convex ribs 6, alignment is facilitated to combine.
In the present invention, the cutting edge number of the cutter head 1 is set as single-blade, twolip or multiple-cutting-edge, and cutter head 1 passes through mold pressure
System is sintered, and cutting edge number can need to be designed according to production；No sword carbide cutter tool can be also inlayed at cutting edge
Piece increases the cutting hardness of cutter head 1.
The above is only the utility model preferred embodiment, is not made in any form to the utility model
Limitation, although the utility model is disclosed as above with preferred embodiment, is not limited to the utility model, any to be familiar with sheet
Technical professional is not departing within the scope of technical solutions of the utility model, is made when using the technology contents of the disclosure above
A little change or the equivalent embodiment for being modified to equivalent variations, as long as being without departing from the content of the technical scheme of the utility model, foundation
The utility model technology refers to belonging to this practicality to any simple modification, equivalent change and modification made by above example
In the range of new technique scheme.
