Description
Technical field
The utility model belongs to numerical control equipment field, in particular to a kind of linear movement of the lathe head of nearly heart distribution is driven
Dynamic device.
Background technique
The head of numerically-controlled machine tool usually cooperates guide rail lead screw to realize along moving for supporting beam by driving motor, and structure is past
Toward being the leading flank that guide rail, lead screw and driving motor are set to supporting beam, head is acted on guide rail by sliding block, this
Structure acts on the front side of supporting beam due to support force completely, causes head to there is phenomenon of toppling forward, and structural rigidity is low,
Kinetic stability is poor.
In order to improve above structure defect, there is a kind of head driving moving structure of double side support, by lead screw and portion
Guide rail is divided to be set to supporting beam top, this structure effectively improves the phenomenon of toppling forward of head, and it is rigid to enhance structure
Property, but since head center of gravity and the position deviation of spindle motor driving effect point are larger, reduce the stationarity of head motion
And reliability, also, under the conditions of full closed loop control grating scale apart from driving force axis farther out, control deviation is also easy to produce, to lead
It causes head Z axis connecting plate to cause the micro- pendulum of structure in the case where inertia force acts on and then generates motor fluctuation phenomenon, final influence head
Vibration resistance and kinetic stability.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide that a kind of structure is simple, and structural rigidity is good, easily
It closely feels at ease dress in grating scale and drive system, vibration resistance is strong, and the good numerically-controlled machine tool head of kinetic stability moves linearly driving
Device.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions: a kind of nearly heart distribution
Lathe head linear movement driving device, by supporting beam, the nose assembly containing electro spindle, side guide, top surface guide rail,
Sliding block, lead screw and driving motor composition, top surface guide rail and two side guides are arranged in parallel, and two side guides are installed on branch
The leading flank of beam is supportted, top surface guide rail is installed on the top of supporting beam；Lead screw is installed on the leading flank of supporting beam, and is arranged in parallel in
Between two side guides, it can be driven and be rotated by driving motor；Nose assembly acts on top surface guide rail and two sides by sliding block
On the guide rail of face, and coupled by nut seat and screw with lead screw, can be led under driving motor effect along top surface guide rail and side
Rail does linear reciprocating motion.
A kind of linear movement driving device of the lathe head of above-mentioned nearly heart distribution, the top surface guide rail and side guide are equal
It is set to the muscle portion position of supporting beam.
A kind of linear movement driving device of the lathe head of above-mentioned nearly heart distribution, the top surface guide rail are located at supporting beam
Top center.
A kind of linear movement driving device of the lathe head of above-mentioned nearly heart distribution, the driving motor is servo motor.
A kind of linear movement driving device of the lathe head of above-mentioned nearly heart distribution, the leading flank of the supporting beam are also set up
There is grating scale component.
Compared with prior art, the utility model has the beneficial effects that: the utility model utilizes " center of gravity driving " principle,
It not only ensure that the structural rigidity of nose assembly, it is ensured that its kinetic stability effectively eliminates the kinematic wave of nose assembly
Dynamic phenomenon；And the muscle portion position distribution of front side rail and top surface guide rail in supporting beam is also easy to guarantee that the installation of guide rail is rigid
Property and straightness, advantageously ensure that moving parts movement guiding performance, further ensure nose assembly operation stability and
Reliability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structure sectional view of the utility model.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing.
Referring to figs. 1 and 2, a kind of linear movement driving device of the lathe head of nearly heart distribution, by supporting beam 1,
Nose assembly 2, side guide 3, side guide 4, top surface guide rail 5, sliding block 6, lead screw 7 and servo motor 8 form.
Side guide 3, side guide 4 and top surface guide rail 5 are parallel to each other, and wherein side guide 3 and side guide 4 are installed on
The muscle portion position of 1 leading flank of supporting beam, top surface guide rail 5 are installed at the reinforcing rib of 1 top center of supporting beam.Lead screw 7 is installed on
The leading flank of supporting beam 1, and be arranged in parallel between side guide 3 and side guide 4, it can be driven and be rotated by servo motor 8.Peace
Nose assembly 2 equipped with electro spindle acts on sliding by sliding block 6 respectively and acts on side guide 3, side guide 4 and top surface
On guide rail 5, and coupled by nut seat and screw-nut with lead screw 7, can in the case where servo motor 8 is acted on along side guide 3,
Side guide 4 and top surface guide rail 5 do linear reciprocating motion.
For the displacement for accurately detecting nose assembly 2, the leading flank of supporting beam 1 is provided with grating scale component 9, due to grating
Ruler component 9 and lead screw 7 and servo motor 8 be mounted on supporting beam leading flank, can be avoided and generates because of the two position deviation
The moment of inertia, and then eliminate the micro- pendulum of structure and the deviation of grating scale feedback position and physical location is caused constantly to change caused movement
Fluctuation.
Center of gravity of the utility model by spindle motor driving with grating scale feedback component close to nose assembly is installed, and is realized
Center of gravity driving, and the position deviation of closed-loop is reduced, it effectively eliminates and is generated farther out due to activation point with position of centre of gravity
Structure it is micro- pendulum and caused by motor fluctuation.
Although the utility model is described in detail above, the utility model is without being limited thereto, art technology
