Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of phase angle guiding mechanism of the two wedges during for Laser Processing.
Background technology
In field of laser processing, particularly the laser boring field for miniature processing with tapered hole, needs the radius of adjustment hole.The adjusting of radius generally is the relative position by the optical element of regulating two synchronous rotaries (such as wedge), makes the laser beam generation deflection angle that deflects.The structure of the processing head of the laser boring that this area is commonly used drives respectively two mechanisms' rotations by two motors, by adjusting both relative rotational, thereby changes both relative positions.
But this adjustment mode is owing to the impact of Electric Machine Control precision, and its relative angle must be subject to the impact of this precision, and its minimum of a value depends on this adjustment precision, can not too approach zero.
And mechanical gear mechanism is not owing to be subjected to the impact of electric machine control system, and it adjusts limiting value can be better close to zero.
Summary of the invention
The purpose of this invention is to provide a kind of position deviation rotating actuator based on gear, this transmission mechanism can reduce the impact of Electric Machine Control precision, has improved the progress that relative angle is adjusted, and has reduced the relative minimum limit value at phase angle.
The objective of the invention is to realize by following technical proposals, specific as follows:
The phase angle guiding mechanism of a kind of pair of wedge, comprise: clutch shaft bearing seat, the second bearing block, annular fixed part, the first sleeve, the second sleeve, the first sleeve and the second sleeve are installed in the annular fixed part, and two ends are installed on clutch shaft bearing seat and the second bearing block by bearing respectively, and its inner ring can be installed wedge; Also comprise tooth bar, spur gear, driving gear, driven gear; Annular fixed part outside is equipped with and drives its driving mechanism that moves up and down; Tooth bar is fixedly mounted on the inner ring of annular fixed part, and its length direction is with axially consistent, and meshes with spur gear, and spur gear and driving gear are installed on the same axle; Driven gear is installed in outer ring and the driving gear engagement of the first sleeve and/or the second sleeve.
Further, driven gear has two, is installed in respectively the outer ring of the first sleeve and the second sleeve, all meshes with driving gear.
Further, described driving mechanism is roller screw.
Further, between clutch shaft bearing seat, the second bearing block, the annular fixed part axis of guide that annular fixed part moves up and down is installed.
Further, described driving gear is bevel gear.
Further, described driven gear is bevel gear.
Further, the position in relative sleeve center of circle symmetry is provided with another tooth bar, another spur gear and another driving gear; This tooth bar also is fixedly mounted on the inner ring of annular fixed part, and its length direction is with axially consistent, and with described another spur gear engagement, described another spur gear and another driving gear are installed on the same axle, described another driving gear and driven gear mesh.
The invention has the beneficial effects as follows:
Reduce the circuit of electric machine control system, improved the progress that relative angle is adjusted, reduced the relative minimum limit value at phase angle.
Description of drawings
Fig. 1 is outline drawing of the present invention.
Fig. 2 is drive mechanism schematic diagram of the present invention.
Fig. 3 is internal structure schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, the guiding mechanism of optical element comprises clutch shaft bearing seat 1, annular fixed part 2, the second bearing block 3; Annular fixed part 2 can move up and down along axle.Annular fixed part 2 inner rings are equipped with the first sleeve 7 and the second sleeve 8, the first sleeves 7 and the second sleeve 8 and are installed on clutch shaft bearing seat 1 and the second bearing block 3 by bearing respectively.The first sleeve 7 and the second sleeve 8 inner rings all are equipped with optical element, such as wedge.
Such as Fig. 2, shown in 3, the outer ring of the first sleeve 7 and the second sleeve 8 all is equipped with a driven wheel of differential 4,9, and the tooth section of these two bevel gears is relative, and the centre is engaged with a drive bevel gear 10.Drive bevel gear 10 and a spur gear 6 are installed on the same axle, rotate synchronously.Spur gear 6 and a tooth bar 5 engagements.As shown in Figure 3, in order to keep the balance of sleeve in the process of rotating, two sets of transmission mechanism are set.Position in relative sleeve center of circle symmetry is provided with a spur gear 6, a tooth bar 5 and a driving gear equally.
When annular fixed part 2 is moved up and down along the axle A among Fig. 1 by external agency's (such as leading screw) driving, tooth bar 5 also moves up and down, thereby driving spur gear 6 rotates, the rotation of spur gear 6 drives again drive bevel gear 10 and rotates, and then drive 2 driven gears with opposite rotation direction rotation, thereby the relative position of the wedge on the first sleeve 7 and the second sleeve 8 is changed.
