Summary of the invention
The technical matters that the utility model mainly solves is to provide a kind of fixture, more specifically to a kind of three-point fix test instrument fixture, support can be moved, thus expand the length range of measured piece, when testing, support can be locked, thus reducing measuring error, bearing has scale, and survey crew directly can read the distance between test specimen two strong point.
For solving the problems of the technologies described above, the utility model relates to a kind of fixture, more specifically to a kind of three-point fix test instrument fixture, comprise seaming chuck, test specimen, support I, bearing, clamping screw I, back-up block, support bar, clamping screw II and support II, support can be moved, thus expand the length range of measured piece, when testing, support can be locked, thus reduce measuring error, bearing has scale, and survey crew directly can read the distance between test specimen two strong point.
The lower end of seaming chuck contacts with the upper surface of test specimen.Test specimen is placed on support I and support II, and support I and support II lay respectively at the two ends of test specimen.Support I is movably connected on one end of bearing, and support II is movably connected on the other end of bearing, and support I and support II can slide on bearing.Clamping screw I passes the side of bearing and is connected with support I.Back-up block is fixed on the lower surface of bearing, and the lower end of back-up block is connected with support bar.Clamping screw II passes the side of bearing and is connected with support II.
As the further optimization of this programme, the bearing described in a kind of three-point fix test instrument of the utility model fixture has scale.
As the further optimization of this programme, the clamping screw I described in a kind of three-point fix test instrument of the utility model fixture can slide along the bar-shaped trough of bearing.
As the further optimization of this programme, the clamping screw I described in a kind of three-point fix test instrument of the utility model fixture is connected with support I through the hole on support I.
As the further optimization of this programme, the back-up block described in a kind of three-point fix test instrument of the utility model fixture and bearing are welded to connect.
As the further optimization of this programme, the groove on the back-up block described in a kind of three-point fix of the utility model test instrument fixture and the termination on support bar in mating connection.
The advantage of a kind of three-point fix test instrument of the utility model fixture is: support can be moved, thus expand the length range of measured piece, when testing, support can be locked, thus reduce measuring error, bearing has scale, and survey crew directly can read the distance between test specimen two strong point.
