The main purpose of the utility model is to provide one kind can axially driving and rotatable electro spindle, the electro spindle Rotary shaft can also be not only axially moved with rotary motion, and be provided with around rotary shaft high-precision guide rail with Precision when ensureing mobile.
To achieve the above objectives, the technical solution adopted in the utility model is:One kind can axially driving and rotatable electricity Main shaft, including pedestal and the fixed cylinder that is fixed on the base, which is characterized in that further include the inside for being placed coaxially on fixed cylinder Moving sleeve, the rotary shaft that is placed coaxially on inside moving sleeve, the rotary shaft can relative to sleeve rotating but not It is axially movable, is provided with along its axially extending multiple guide rail in the outer surface of the sleeve, is at least set on each guide rail It sets there are one sliding block, the sliding block is fixed in fixed cylinder, is provided in fixed cylinder and positioned at the end of moving sleeve built-in Motor, the built-in motor are connect with transmission of rotary axis.
Preferably, radially uniform setting of multiple guide rails along sleeve.
Preferably, there are two sliding blocks, each sliding block to be fixed in fixed cylinder by mounting hole for setting on each guide rail.
Preferably, axial direction electric machine is additionally provided on pedestal, the output shaft of the axial direction electric machine is connect with screw rod transmission, institute It states lead screw to be arranged in parallel with rotary shaft, the pair of nut coordinated with wire rod thread is provided on lead screw, the pair of nut passes through company Bar is connect with built-in motor.
Preferably, the both ends of the lead screw are respectively supported at by bearing block in fixed cylinder and pedestal.
Compared with prior art, the utility model has the advantages that:
Rotary motion not only may be implemented in the rotary shaft of the utility model, but also may be implemented to be axially moved, and sleeve with It is provided with multiple guide rails and sliding block between fixed cylinder, can effectively ensure stability of the rotary shaft when being axially moved in this way, And then can ensure stability when rotation, and then improve machining accuracy.

Fig. 2 is the A-A views of a preferred embodiment according to the present utility model
Fig. 3 is the stereogram of a preferred embodiment according to the present utility model
Specific implementation mode
It is described below for disclosing the utility model so that those skilled in the art can realize the utility model.It retouches below Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
As shown in Figs. 1-3, one kind can axially driving and rotatable electro spindle, including pedestal 1, be fixed on pedestal 1 Fixed cylinder 2, be placed coaxially on fixed cylinder 2 inside moving sleeve 3 and rotary shaft in the inside of moving sleeve 3 is set 5, the sleeve movement 3 can be slided along the axis of fixed cylinder 2, and the rotary shaft 5 is coaxially disposed with moving sleeve 3, and is rotated Axis 5 is rotated with moving sleeve 3 but opposite can not axially be slided and then when moving sleeve 3 slides axially relative to fixed cylinder 2 Can drive rotary shaft 5 move axially, and then can drive mounted on the Cutting tool installation manner end of electro spindle cutter axial movement and Rotation.Specifically, it can be connected by multiple bearing (not shown) between the moving sleeve 3 and rotary shaft 5 and be moved with reducing Friction between moving sleeve 3 and rotary shaft 5.
The multiple guide rails 13 axially extended are provided on the moving sleeve 3, multiple guide rails 13 are along moving sleeve 3 Outer surface circumference on be uniformly arranged.There are two sliding blocks 14, the sliding block 14 to pass through fixed block for setting on each guide rail 13 15 are fixed in fixed cylinder 2, in this way, when moving sleeve 3 is slided relative to fixed cylinder 2, pass through the work of guide rail 13 and sliding block 14 With the shaking that can effectively reduce moving sleeve 3 improves machining accuracy in turn.
It is provided with built-in motor 4 in the fixed cylinder 2 and positioned at the end of moving sleeve 3, the built-in motor 4 can As moving sleeve 3 is axially moveable relative to fixed cylinder 2, the built-in motor 4 is sequentially connected with rotary shaft 5, in this way when interior When setting motor 4 moving sleeve 3 is followed to move axially, it can also drive rotary shaft 5 to rotate and then realize the axis of rotary shaft 5 To mobile and rotary motion.
Axial direction electric machine 6 is additionally provided on pedestal 1, output shaft and the lead screw 7 of the axial direction electric machine 6 are sequentially connected, described Lead screw 7 is arranged in parallel with rotary shaft 5, and the both ends of the lead screw 7 11 He of bearing block by being arranged in fixed cylinder 2 respectively It is arranged on the bearing block 12 on pedestal 1, bearing is both provided between lead screw 7 and bearing block 11 and bearing block 12.The axis It is sequentially connected to the output shaft of motor 6 by shaft coupling 8 and lead screw 7.
It is provided in lead screw 7 and is connected by connecting rod 10 and built-in motor 4 with the pair of nut of its screw-thread fit 9, the pair of nut 9 It connects, in this way when axial direction electric machine 6 rotates, pair of nut 9 can be moved along the axis of lead screw 7, and lead screw 7 is driven interior by connecting rod 10 The axial movement that motor 4 moves axially and then drives rotary shaft 7 is set, the axial movement of cutter is thereby realized.
Since lead screw 7 is arranged in the outside of fixed cylinder 2, in order to facilitate the company of connecting rod 10 and pair of nut 9 and built-in motor 4 It connects, is provided with the strip-shaped hole extended along the axis direction of fixed cylinder 2 at position corresponding with connecting rod 15 in the fixed cylinder 2 16, the connecting rod 10 is passed through from strip-shaped hole 16, and can be moved back along the axis direction of rotary shaft 5 in strip-shaped hole 16 It is dynamic.
