Abstract
The utility model discloses a kind of plate test bridge plate, comprise slide rail (1), the first linear bearing (2), the first locating shaft (3), the second graduation indication pin (7), the first rule (8), the first positioning fixture (9), the first bolt (10) etc.Slide rail (1) coordinates composition two kinematic pairs with the first linear bearing (2), the second linear bearing (4), can realize arbitrary span regulate by the slip of the first linear bearing (2), the second linear bearing (4); The first rule (8) be arranged on slide rail (1) can be used for reading stride values; First linear bearing (2) is provided with the first locating shaft (3), the first locating shaft (3) contacts with tested flat board; Be arranged on the surface that the first positioning fixture (9) on slide rail (1) and the second positioning fixture (11) are used for Small angle measuring instrument to be fixed on slide rail (1), make location bridge plate bridge plate and Small angle measuring instrument form new measuring system.
Description
Technical field
The utility model relates to a kind of pick-up unit, relates in particular to a kind of location bridge plate.
Background technology
Bridge plate is the sheet metal with two carrying planes.Distance between bridge plate two supports locating shaft center line is called bridge plate span, and span is determined according to tested slab length and accuracy requirement.Bridge plate is the important tool embodying pitch order measuring principle, and it directly affects the evaluation with error amount that obtains of flatness measurement data.
Before level(l)ing plate, first calculate bridge plate span, then regulate bridge plate span, be placed on above bridge plate by the low-angle instrument of the scope of taking measurement of an angle within 5 °, now, bridge plate and low-angle instrument form a measuring system; In level(l)ing plate process, read the displayed value of low-angle instrument, displayed value is multiplied with bridge plate span, draw dull and stereotyped difference in height between span, the like, calculate dull and stereotyped flatness error.
Tradition bridge plate error is 0.01-0.03mm, error is large, regulates span poor continuity, and level meter, electrolevel such as cannot to fix at the shortcoming on bridge plate, thus the measuring system precision causing traditional bridge plate and level meter, electrolevel to form is low unreliable, is not suitable for level(l)ing plate.
Summary of the invention
The purpose of this utility model is to provide the bridge plate that a kind of error can control within 10 μm.
A kind of plate test bridge plate, comprises slide rail, the first linear bearing, first locating shaft, the second linear bearing, the second locating shaft, first graduation indication pin, the second graduation indication pin, the first scale, first positioning fixture, the first bolt, the second positioning fixture, second bolt, 3rd graduation indication pin, the 4th graduation indication pin, the second rule.
Slide rail coordinates component movement secondary with the first linear bearing, the second linear bearing, the first linear bearing, the second linear bearing can be free to slide on slide rail; Slide rail both sides install the first rule and the second rule respectively, are connected by Bolt to position; Slide rail both sides have some threaded holes, are provided with the first positioning fixture and the second positioning fixture, are bolted connection.
First linear bearing bottom surface is provided with the first locating shaft, and the first locating shaft is bolted on the first linear bearing bottom surface; First linear bearing both sides are separately installed with the first graduation indication pin and the 3rd graduation indication pin, are bolted connection.
Second linear bearing bottom surface is provided with the second locating shaft, and the second locating shaft is bolted on the second linear bearing bottom surface; Second linear bearing both sides are separately installed with the second graduation indication pin and the 4th graduation indication pin, are bolted connection.
First positioning fixture is installed the first bolt, by thread connection, the first bolt can be moved up and down by the screw thread on the first positioning fixture.
Second positioning fixture is provided with the second bolt, by thread connection, the second bolt can be moved up and down by the screw thread on the second positioning fixture.
As mentioned above, adopt the linear bearing line slide rail minimum with flatness error to coordinate, reduce the flatness error of bridge plate; Adopt bilateral to read span numerical value, facilitate operation, decrease span error; Adopt low-angle instrument locating device, avoid instrument sliding phenomenon, improve the accuracy of measuring system, and improve detection efficiency.It is simple that this bridge plate has assembling, and quality of fit is high, detection efficiency advantages of higher.
