Description

A kind of HSK knife handle tool changing device

Technical field

The utility model relates to a kind of knife handle tool changing devices, more particularly to a kind of HSK knife handle tool changing device.

Background technique

It is understood that high revolving speed machining center mostly uses HSK knife handle now, in order to guarantee that main shaft precision is lasting, main shaft is prevented Locating bias, after HSK knife handle needs are removed from main shaft, manual tool changing.But when manual tool changing, it is easy to influence since knife handle rotates Tool changing precision, and tool changing efficiency is lower.Therefore it needs to make a set of tool changing device, knife handle can be limited in manual tool changing and is turned It is dynamic, facilitate tool changing.

Summary of the invention

The utility model, in tool changing, is easy to influence tool changing precision for existing high-speed machining center since knife handle rotates, And the lower technical problem of tool changing efficiency, provide one kind can limit knife handle rotation, facilitate tool changing, structure it is simple, using the longevity Order long HSK knife handle tool changing device.

For this purpose, the technical solution of the utility model is, a kind of HSK knife handle tool changing device is equipped with knife handle support base, knife handle branch It supports seat and is equipped with keyway, be equipped with locking key in keyway, locking key is matched with the keyway on knife handle, is additionally provided with circle on knife handle support base Hole, circular hole is interior to be equipped with straight pin, and straight pin is matched with the circular hole on knife handle, and straight pin is equipped with cylinder pin locking screw.

Preferably, knife handle support base is equipped with screw hole.

Preferably, locking key is equipped with locking key lock-screw.

Preferably, it is step cylinder-like structure that knife handle support base, which places one end of knife handle,.

The utility model beneficial effect is,

(1) due to using the technology described above, when HSK knife handle needs tool changing, HSK knife handle need to be only pushed into knife handle support , the slot on knife handle is stopped key and blocks, and prevents knife handle from rotating, and is inserted into straight pin, locks cylinder pin locking screw, i.e., available special The cutter on HSK knife handle is unclamped with spanner, realizes that cutter is fast and accurately replaced, structure is simple, easy to operate.

(2) since locking key is equipped with locking key lock-screw, when long-time leads to stop using HSK knife handle tool changing device When key is worn, as long as unclamping locking key lock-screw, stop key position can be adjusted, get out of the way the abration position of key and connect with knife handle Synapsis is equivalent to and has replaced new locking key, easy to adjust, quick.

(3) due to being equipped with cylinder pin locking screw, straight pin axial float can be prevented, avoids straight pin from knife handle circle It falls off in hole, influences positioning accuracy.

It (4), can be fixed on the table by knife handle support base by screw since knife handle support base is equipped with screw hole.

Specific embodiment

The utility model is described further below with reference to embodiment.

A kind of HSK knife handle tool changing device, is equipped with knife handle support base 1, sets that there are two screw hole 6, screws on knife handle support base 1 It is equipped with screw in hole 6, knife handle support base 1 is fixed on workbench by screw, screw hole 6 is counter sink, ensure that spiral shell It also will not influence the clean and tidy of 1 surface of knife handle support base after nail is fixed, two sides are also used as surface platform use.Knife handle support base 1 one end for placing knife handle is step cylinder-like structure, and after knife handle is put into knife handle support base 1, step can play Auxiliary support Effect.

Knife handle support base 1 is equipped with keyway, is equipped with locking key 2 in keyway, and locking key 2 is matched with the keyway on knife handle, can To prevent knife handle from rotating, locking key 2 is equipped with locking key lock-screw 3, inevitable after long-time uses HSK knife handle tool changing device So that locking key 2 is generated abrasion, as long as unclamping locking key lock-screw 3,2 position of locking key can be adjusted, get out of the way abration position With knife handle contact position, it is equivalent to and has replaced new locking key, it is easy to adjust, quick, at low cost.

It is additionally provided with circular hole on knife handle support base 1, is equipped with straight pin 5 in circular hole, straight pin 5 is matched with the circular hole on knife handle, Straight pin 5 fixes knife handle, and straight pin 5 is equipped with cylinder pin locking screw 4, prevents straight pin 5 from causing because of axial float from knife It falls off in the circular hole of handle, causes failure of apparatus.

When HSK knife handle needs tool changing, HSK knife handle need to be only pushed into knife handle support base 1, the slot on knife handle is stopped key 2 It blocks, prevents knife handle from rotating, be inserted into straight pin 5, lock cylinder pin locking screw 4, i.e., available special spanner unclamps on HSK knife handle Cutter, realize cutter fast and accurately replace, structure is simple, easy to operate.

Only as described above, only specific embodiment of the utility model, when the utility model cannot be limited with this The range of implementation, therefore the displacement of its equivalent assemblies, or according to equivalent changes and modifications made by the utility model patent protection scope, It should still belong to the scope that the utility model claims book is covered.
