Described X-axis regulation bolt 7 and Y-axis regulation bolt 8 are in same level on the barrel of described regulating part main body 1 On face, being each provided with more than 2, described X-axis regulation bolt 7 and Y-axis regulation bolt 8 are arranged for interval.Described tune Joint part main body 1 inner peripheral surface on be formed a circle to central shaft protrude for horizontal adjustment block 3 is carried out spacing boss 12, Described X-axis regulation bolt 7 and Y-axis regulation bolt 8 are positioned at the lower section of described boss 12, described axial angle regulation bolt 9 tops being positioned at described boss 12.
Described horizontal adjustment block 3 includes the main body of column structure, and the diameter of described column structure main body is less than described boss 12 Internal diameter, the main body of described column structure is formed a circle positioning table 13, the diameter of described positioning table 13 be less than described regulation The internal diameter of part main body 1, more than the internal diameter of described boss 12, the top of the main body of described column structure be formed with for axle The top cap 14 of the convex globoidal structure combined to the bottom surface of angle-regulating block 4, the diameter of described top cap 14 is more than horizontal adjustment block 3 The diameter of column structure main body, equal with the internal diameter of described boss 12, the crown of described top cap 14 is cambered surface protruding upward, And be that sphere-contact is connected with the lower surface of described axial angle regulating block 4, the upper table surface of described positioning table 13 and described top cap Distance between the bottom surface of 14 is more than the height of institute's boss 12.
Described axial angle regulating block 4 is ┷ shape structure, and the base diameter of described ┷ shape structure is more than horizontal adjustment block 3 top The diameter in face, the bottom face of described ┷ shape structure be formed be inwardly recessed for described horizontal adjustment block 3 upper surface The cancave cambered surface connected for sphere-contact, the top of described ┷ shape structure vertical part is positioned at the upper flange 6 on regulating part main body 1 top In the flange hole at center, and it is being axially formed the sensor fixing hole 10 being inwardly recessed.
A kind of XYZ tri-shaft assignment adjusting means of the mechanics machine of the present invention, have concurrently plane XY direction centering regulatory function and Axial angle regulatory function.First, by the mating spherical surfaces position, bottom of axial angle regulation bolt regulation axial angle regulating block, The axial angle deviation of fixture and lower clamp in elimination;Then, water is adjusted by regulation X-axis regulation bolt and Y-axis regulation bolt Heibei provincial opera locking nub position on work platforms, makes fixture realize centering.During regulation, the most preferentially ensure axial angle pair In, fixture and the alignment deviation in lower clamp XY direction on successive elimination;Finally, after regulation to be centred completes, regulating part is utilized Boss locking horizontal adjustment block in the middle part of main body, utilizes the axial locking screw lock axial angle regulating block in upper flange.
Below in conjunction with Fig. 5, the detailed description of the invention of the XYZ tri-shaft assignment adjusting means of a kind of mechanics machine of the present invention is done in detail Describe:
The purpose of the XYZ tri-shaft assignment adjusting means of a kind of mechanics machine of the present invention is by regulation bolt regulation horizontal adjustment Block and axial angle regulating block position in the plane, thus thoroughly plane alignment deviation and the axial angle of the upper lower clamp of elimination miss Difference.Then the boss utilizing the axial locking bolt on upper flange and regulating part main body locks axial angle-regulating block and level respectively Regulating block.
As it is shown in figure 5, after testing machine life-time service, a series of alignment deviation can be produced, finally make to be connected with motor output shaft Upper compressed chuck with and the lower compressed chuck that is connected of sensor 25 produce axial misalignment, plane alignment deviation, examination now The machine of testing is compressed during test bringing bigger error.Utilize the XYZ tri-shaft assignment regulation dress of a kind of mechanics machine of the present invention After putting 15 regulations, effect as shown in Figure 5 can be reached: even if the motor of testing machine exports main shaft and horizontal plane out of plumb, on There is a series of alignment deviation in fixture 20 and lower clamp 22, ensure that after utilizing assembly of the invention regulation fixture 20 and under Fixture 22 entirely on the center.Specific implementation process is as follows:
First should be by regulation axial angle regulation bolt, the axial angle deviation of fixture 20 and lower clamp 22 in elimination, at axle During regulation, the upper end sphere of horizontal adjustment block contacts with the lower end sphere face all the time of axial angle regulating block, horizontal adjustment The sphere center position of the upper end sphere of block immobilizes, it is possible to realize axial angle regulating block any direction in certain angle θ Rotation.After axial angle deviation eliminates, regulation should be continued when fixture 20 and lower clamp 22 on ensureing fit tightly The centering in XY direction.This is because continue regulation X-axis regulation bolt and Y-axis regulation bolt, horizontal adjustment block is planar Position deviation, but after horizontal adjustment block plan-position changes, the sphere center position of its upper end sphere position the most therewith can change therewith Become, the axial alignment of the first step can be affected, so the axial alignment of axial angle regulating block must be regulated in real time, it is also possible to pass through Axial angle regulation bolt and X-axis on the same axial location of adjusted in concert regulate bolt and Y-axis regulation bolt realization.
After centering has regulated, needing to lock adjusting means, in order to carry out next step test, this device utilizes level Regulating block lower surface exceeds the distance of 0.5mm than regulating part main body lower surface distance, tightens the bolt of regulating part bottom part body flange, Horizontal adjustment block is locked by boss lower surface.The flange tightening upper flange fixes screw, locks axial angle-regulating block.
