Description
[technical field]
The utility model relates to a kind of machining center cutter head.
[background technology]
The tradition machining center adopts and drives the cutter head high speed rotating by mechanical driving device, and the cutter that is used to process is fixedly mounted on the cutter head along with the one superhigh speed rotates.There is following shortcoming in existing this cutter drive mechanism: at first cutter head is removably to be inserted on the machining center, makes its rotating speed be restricted; Secondly cutter head comes transmission by mechanical driving device, and mechanical driving device itself is also wanted fast turn-around, also makes the final rotating speed of cutter be subjected to the restriction of mechanical driving device mechanical performance, exists when running up to vibrate shortcoming big, poor stability.In order to realize the fine finishining to product, people press for more high-revolving cutter, therefore are necessary to improve the accelerator of existing cutter.
[utility model content]
The utility model has overcome the deficiencies in the prior art, provides simple in structure, shake little, good stability, a kind of machining center cutter head that rotating speed is high.
In order to address the above problem, the utility model adopts following technical proposals:
A kind of machining center cutter head includes body of tool bit, it is characterized in that being provided with motor in the described body of tool bit, is provided with to be used for the fixed structure of mounting cutter on the output shaft of motor;
Described body of tool bit bottom is provided with the cavity under shed, and described motor fuselage is arranged in the above-mentioned cavity and stretch out outside the cavity rotating shaft outer end;
Described body of tool bit middle part has the entrance hole that is communicated with described cavity upper end, and the stem line on the described motor passes above-mentioned entrance hole and links to each other with extraneous power supply;
Also be provided with the cylinder that is close on its inwall in the described cavity, described motor fuselage is arranged in the cylinder, is provided with bearing between at the bottom of motor fuselage and the cylinder tube, also has the through hole that passes for described rotating shaft at the bottom of the cylinder tube;
Be provided with the tank that cooling motor is used between described motor circumference and the described cylinder, the cooling water of tank links to each other with extraneous water-supply-pipe into and out of the entrance hole of pipe by described body of tool bit middle part;
Described body of tool bit bottom also has the screw that communicates with described cavity, is equipped with the screw that is used for fixing described cylinder in the screw;
Described fixed structure comprises the groove that radially runs through along described motor output shaft outer end, and described cutter upper end is positioned at groove, and the groove both sides form the elastic clip of downward extension, and two elastic clips also are set with outward and are used for the clamp ring of clamp-on tool.
The beneficial effects of the utility model are: cutter directly is fixedly mounted on the motor output shaft, avoided when using mechanical driving device influence that rotating speed and transmission stability are brought, also can realize the high speed rotation of cutter by direct raising motor power output, simple in structure, shake little, good stability; It is overheated to adopt simultaneously when the motor circumference is provided with tank and prevents machine operation, has prolonged service life of the present utility model.

[specific embodiment]
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
As shown in the figure, a kind of machining center cutter head includes the body of tool bit 1 that is inserted on the machining center and can disassembles, and is provided with motor 2 in the body of tool bit 1, is provided with to be used for the fixed structure 3 of mounting cutter 8 on the output shaft of motor 2.
In the utility model, fixed structure 3 comprises the groove 31 that radially runs through along motor 2 output shaft outer ends, cutter 8 upper ends are positioned at groove 31, groove 31) side forms outer also being set with of elastic clip 311, two elastic clips 311 of downward extension and is used for the clamp ring 32 of clamp-on tool 8.Body of tool bit 1 top is bullet connecting portion 11, and bullet connecting portion 11 can be pegged graft with the installing hole on the machining center and closely link to each other.Body of tool bit 1 bottom is provided with the cavity 12 under shed, and motor 2 fuselages are arranged in the above-mentioned cavity 12 and stretch out outside the cavity 12 rotating shaft 21 outer ends.Body of tool bit 1 middle part has the entrance hole 13 that is communicated with cavity 12 upper ends, and the stem line on the motor 2 passes above-mentioned entrance hole 13 and links to each other with extraneous power supply.
Also be provided with the cylinder 5 that is close on its inwall in the cavity 12, motor 2 fuselages are arranged in the cylinder 5, are provided with bearing 6 between at the bottom of 5 of motor 2 fuselages and the cylinders, also have the through hole 51 that passes for rotating shaft 21 at the bottom of 5 of the cylinders.Be provided with the tank 52 of cooling motor 2 usefulness between motor 2 circumference and the cylinder 5, the cooling water of tank 52 links to each other with extraneous water-supply-pipe into and out of the entrance hole 13 of pipe by body of tool bit 1 middle part.Body of tool bit 1 bottom also has the screw 15 that communicates with cavity 12, is equipped with the screw 6 that is used for fixing cylinder 5 in the screw 15.
During work, with motor 2 power turn-ons, make simultaneously at extraneous water pump and carry cooling water toward tank 52, because cutter directly is fixedly mounted on the output shaft of motor 2, the influence that can bring rotating speed and transmission stability when having avoided using mechanical driving device, thus can realize the high speed rotation of cutter by direct raising motor 2 power outputs, simple in structure, shake little, good stability; It is overheated to adopt simultaneously when motor 2 circumference are provided with tank 52 and prevent motor 2 work, has prolonged service life of the present utility model.
