Description
Technical field
The present invention relates to electro spindle field more particularly to a kind of air-cooled numerical control automatic tool changing electrical spindles.
Background technique
Automatic tool changing electrical spindle is a kind of very high electromechanical integrated product of technology content, is mainly used in numerical control processing
Scheming bed.
In the prior art, its fanning wind cooling numerical control automatic tool changing electrical of the wood engraving and milling of Patent No. CN201120387962.9
Main shaft, Patent No. CN201710642766.3 from fanning wind cooling numerical control automatic tool changing electrical spindle, rod assembly end activity hiding
If during being pushed using rod assembly by pushing portion, steel ball can be fallen into annular groove, can be pressed from both sides there are two the steel ball being oppositely arranged
Tight knife handle can then be unclamped conversely, two steel ball frees opening loosens pulling claw by the external knife handle that two steel balls clamp by pulling claw, complete
Unload knife.Such installation way is from clamping in the middle part of knife handle, and clamping force is small, is easy to loosen, in addition not can guarantee master in the prior art
To aequum caused by rotor part decentraction, when maintenance, is not easy to tear open the aequum and knife handle cutter of axis and rotor part
It unloads, maintenance cost is high.
Since automatic tool changing electrical spindle needs high speed rotation to process, on the one hand to automatic tool changer main shaft clamping knife handle
It is very high to tense force request, in another aspect spinning process, to the aequum of rotor part and main shaft, knife handle cutter to rotor
Aequum caused by component decentraction also has sizable requirement, while needing to save maintenance cost.
Summary of the invention
The purpose of the present invention is in view of the drawbacks of the prior art, provide a kind of tightening force for being able to solve the above problem it is big,
The high air-cooled numerical control automatic tool changing electrical spindle of the aequum of rotor part and main shaft.
The present invention is achieved through the following technical solutions: a kind of air-cooled numerical control automatic tool changing electrical spindle, including casing with
And stator component, rotor part, main shaft and the bearing being connect with main shaft being arranged in casing.
Firstly the need of consideration be automatic tool changer main shaft clamping knife handle tightening force problem.In the prior art, typically
It is fallen into annular groove using the steel ball of tie rod end, thus from clamping knife handle in the middle part of knife handle, however there is no in view of when knife handle
The case where tightening force increases, experimental data shows to be clamped from middle part using steel ball, when knife handle tightening force reaches 230N or more,
Knife handle easily loose or dislocation, it is extremely dangerous in high speed rotation, while being difficult to adjust knife handle cutter and rotor part decentraction is drawn
The aequum risen.
Therefore, how to enhance the tightening force of tool changing electrical spindle, can make knife handle clamping power between 230N~330N still not
The phenomenon that will appear knife handle loose or dislocation, additionally facilitates and adjusts the aequum of main shaft and rotor, adjusts knife handle cutter to rotor portions
Aequum caused by part decentraction is present invention technical problem urgently to be resolved.
The present invention is specially designed automatic tool changer component, and the automatic tool changer component includes pull rod, knife handle, claw, guiding
Set, installation block set and elastic component, the main shaft is interior to be equipped with installation cavity, and the installation cavity end successively has along main axis length direction
Limit inner cone chamber, adapter cavity, the first clamping chamber and the cushion chamber being mutually communicated, it is intracavitary that the knife handle end is plugged on limit inner cone
And there is the second clamping chamber in knife handle end, knife handle end leans with main shaft end face, and the pull rod is actively located in installation cavity
Interior, the installation block set is arranged in cushion chamber and is socketed on pull rod, and the elastic component, which is socketed on pull rod and is arranged, is pacifying
In encapsulation seat, the guide sleeve is fixedly connected with pull rod and leans with elastic component, and guide sleeve includes being integrally formed, being sequentially connected
The first conically shaped set, the second cylindrical drum set and third conically shaped set, first conically shaped be set on limit inner cone it is intracavitary,
Second cylindrical drum is set in adapter cavity, and it is intracavitary that the third conically shaped is set on the first clamping, and the claw is inserted
It connects in installation block set, claw is equipped with several and divides along its length along guide sleeve periphery circumferential uniformly arrangement, claw
Not Ju You the first clamping portion and the second clamping portion, the outer surface of each first clamping portion of each claw surrounds first conical surface and its interior table
Face surrounds second conical surface, and first conical surface and the second clamping chamber inclined wedge cooperation, second conical surface and the first conically shaped set are oblique
Wedge cooperation, the outer surface of second clamping portion surrounds the third conical surface and its inner surface surrounds the 4th conical surface, the third conical surface
With the first clamping chamber inclined wedge cooperation, the 4th conical surface and the set inclined wedge cooperation of third conically shaped, pull rod drive guide sleeve along pull rod
Movement of the length direction far from knife handle makes guide sleeve that each claw be driven to expand outwardly, thus clamping knife handle end.
The taper of the limit inner cone chamber is 5.71 °.
For the ease of clamping, the knife handle end is circular cone column, circular cone column setting it is intracavitary in limit inner cone and with limit
Position inner cone cavity gap cooperation, circular cone column bottom end face leans with limit inner cone top of chamber end face.
For the ease of pull rod buffering, reduces vibration, reduces the damage to bearing, the elastic component includes stop collar, spring
And cushion, the stop collar be socketed on pull rod and with pull rod clearance fit, between stop collar inner wall and pull rod have ring-type
Grafting gap, the one end of the guide sleeve far from knife handle is movable to be plugged in cyclic annular grafting gap, and stop collar is far from claw
