Description
Technical field
It the utility model is related to fixing tool, and in particular to heat sink processes special tooling.
Background technology
Heat sink used in special occasions, including the housing that cross section is octagon structure, the side where each side
On offer pore structure, and the housing is integrally thin-wall construction.Scroll chuck or chuck on existing lathe are very
Hardly possible is gripped, even and if the heat sink is easy to deform during pore structure is processed on folder reluctantly.
The content of the invention
The purpose of this utility model is to provide heat sink processing special tooling, can not be right to solve lathe of the prior art
The problem of heat sink is processed.
To achieve the above object, the heat sink processing special tooling of the utility model adopts the following technical scheme that：Heat sink
Special tooling, including pedestal are processed, the confession workpiece to be added that pedestal includes column part and is integrally connected on column part coincide
The installation section of installation, the cross section of peace transfer part point is octagon structure, and each side of installation section is provided with chamfered transition
Plane, the connection structure for being connected with lathe is provided with the end face of column part, between installation section and column part
Step surface forms the positioning surface being used for workpiece location fit to be added, is provided with the end face of installation section for machined part
The pressing device being fixed and clamped, on each side of installation section and in chamfered transition plane with the pore structure on the housing of heat sink
Corresponding processing groove.
Bolt hole is provided with end face on the installation section, pressing device includes being used for and workpiece compression fit to be added
Pressing plate and be threaded onto on pressing plate for the hold-down bolt that is connected with bolt hole.
Annular groove is arranged concentrically on the column part, which further includes for filling in the connecting plate being loaded in annular groove
With the connection bolt being threaded onto on connecting plate, which further includes the cushion block for being arranged between connecting plate and lathe,
It is equal that the thickness of cushion block is equipped with the distance between the end face of column part of connection structure with annular groove distance.
The beneficial effects of the utility model：Special tooling is connected by the connection structure being arranged on pedestal with lathe, fixed
Plane positions heat sink, and heat sink is fixed in pressing device, and process tool can be carried out by processing groove
Required pore structure is processed on the side of workpiece to be added, the installation can not be processed by solving lathe in the prior art
The problem of.
Brief description of the drawings
Fig. 1 is the structure diagram one of one embodiment of the heat sink processing special tooling of the utility model；
Fig. 2 is the structure diagram two of heat sink processing special tooling in Fig. 1.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out

One embodiment of the heat sink processing special tooling of the utility model：As Figure 1-Figure 2, including pedestal, base
Seat includes the installation section 2 of column part 1 and the installation that coincide for workpiece to be added being integrally connected on column part 1, pacifies transfer part
The cross section for dividing 2 is octagon structure, and chamfered transition plane 4 is provided between each side 3 of installation section 2.Column part 1
End face on be provided with connection structure 7 for being connected with lathe, connection structure 7 is the connection being connected for the chuck with lathe
Column.Step surface 5 between installation section 2 and column part 1 forms the positioning surface being used for workpiece location fit to be added, mounting portion
The pressing device for being fixed and clamped to machined part is provided with points 2 end face, on each side 3 of installation section 2 and chamfering
Processing groove 8 corresponding with the pore structure on the housing of heat sink in transition plane 4.
Bolt hole 9 is provided with end face on installation section 2, pressing device includes being used for and workpiece compression fit to be added
Pressing plate and be threaded onto on pressing plate for the hold-down bolt that is connected with bolt hole 9.Annular groove 6 has been arranged concentrically on column part 1, should
Special tooling is further included for filling in the connecting plate being loaded in annular groove 6 and the connection bolt being threaded onto on connecting plate, the special tooling
The cushion block for being arranged between connecting plate and lathe is further included, the thickness of cushion block is equipped with the cylinder of connection structure with annular groove distance
The distance between partial end face is equal.
In the other embodiment of the utility model, annular groove is not provided with column part, and the end face on column part
One substrate of upper setting, connecting pole are arranged on substrate, and the diameter of substrate is more than the diameter of column part, at this time connecting plate and base
Plate compression fit.
