100 rear end face.Stretching shield 200 and anterior shield 100 are connected by telescopic oil cylinder 60 and telescopic oil cylinder 70.
If laser 10 is installed vertically, as soon as the light beam of transmitting is a horizontal line, do not pressed from both sides with the axis of stretching shield 200
Angle.But in actual laser installment work, since it is desired that mounting frame of laser is first welded in stretching shield end face with welding rod point
On, artificial to measure bracket both sides to the distance of stretching shield by graduated scale, graduated scale minimum resolution is 1mm.Human eye goes to differentiate,
There will be error within 1mm.In addition, artificial four angles of spot welding, when due to spot welding, hand steered the strength and intensity of bracket lip of people
Difference, bracket inevitably have certain movement (very little), and to sum up the distance of the position at four angles to stretching shield has error, can not
Guarantee completely vertical.Therefore, because laser 10 is difficult to accomplish the right angle setting on stretching shield 200, transmitting light beam is not horizontal,
There is certain angle.
