The thread rotary orientation of the first end and second end of bar 125 is on the contrary, therefore the first threaded connector 126 and the second threaded connector 127
The distance between can increase or reduce with the progress of linear motion, change hinged with the first threaded connector 126 respectively
It first upper connecting rod 121 and the first lower connecting rod 122 and connects on hinged with the second threaded connector 127 second respectively
The tilt angle of bar 123 and the second lower connecting rod 124 relative to screw rod 125, and then change the first attachment base 13 and first base
Difference in height between 11.Since the structure of the second height adjustment mechanism 22 is identical as the structure of the first height adjustment mechanism 21, because
This can also accordingly change the difference in height between the second attachment base 23 and second base 21.And by adjusting 13 He of the first attachment base
The difference in height between difference in height and the second attachment base 23 and second base 21 between first base 11, on the one hand for every
For in a pilot unit, it can be ensured that the extending direction of gib block 30 is parallel to the mounting surface of guide rail, avoids individually being oriented to single
The problem of mounting surface of member is uneven；On the other hand for entire guide rail, it can be ensured that the guiding of all pilot units
Item 30 is located in same level, avoids the problem that the mounting surface of multiple pilot units is uneven.
For the embodiment of the present invention by the way that guide rail is divided into linearly spaced multiple pilot units, each guiding is single
Member includes first base, the first height adjustment mechanism, the first attachment base, second base, the second height adjusting structure, the second company
Joint chair and gib block can adjust the height of two supporting points of multiple pilot units and each pilot unit respectively, so that
Multiple gib blocks on rugged mounting surface are respectively positioned on sustained height, effectively guide rail are avoided to bend, to be conducive to
Improve the stability of linear motor work.In addition, being articulated and connected respectively in screw rod two sides for single height adjustment mechanism
Bar, is conducive to the tilt angle of each connecting rod relative level of well-balanced adjustment, and whole stability is preferable.
