Abstract
The utility model discloses a flatness test rack comprising a radial triangular frame, three screw support legs and a dial indicator, wherein the triangular frame is formed by fixing three horizontal beams around a same center point, an included angle formed by two adjacent horizontal beams is 120 degrees, a plurality of positioning screw holes are arranged on each of the horizontal beams, the three screw support legs are respectively matched with the three horizontal beams in a one-to-one correspondence mode, the screw support legs pass through the positioning screw holes of the corresponding horizontal beams and are arranged perpendicular to the horizontal beams, the dial indicator is fixedly arranged on the center point of the triangular frame, a measuring rod of the dial indicator is parallel with a plumb line, and the lower end of the measuring rod is provided with a measuring head. According to the utility model, screw rods pass through the positioning screw holes of the horizontal beams to be used as the support legs, the height of the horizontal beams can be adjusted up and down along the screw support legs, and the screw rods can pass through the positioning screw holes in different positions to play a role of span adjustment, which enables the flatness test rack to adapt to a variety of samples of different sizes and have universality; and the accuracy of testing is improved as the dial indicator is used as a testing tool.
Description
Technical field
The utility model relates to the testing jig field, particularly a kind of testing flatness frame.
Background technology
Present testing flatness shelf structure is simple, function singleness, and the flatness that can only test the given shape sample does not possess versatility.
The utility model content
Technical problem to be solved in the utility model is for shortcomings and deficiencies of the prior art, and a kind of testing flatness frame is provided, and this testing flatness frame height and span are adjustable, and be adaptive with the sample of various different sizes, possesses versatility.
The technical matters that the utility model solves can realize by the following technical solutions:
The testing flatness frame is characterized in that, comprising:
The one radial tripod that is fixedly formed around same central point by three horizontal beams, adjacent two horizontal beam angles are 120 °, are provided with some positioning screw holes on each horizontal beam;
With three horizontal beams, three screw rod legs of corresponding matching one by one, each screw rod leg passes positioning screw hole and arrange vertical with horizontal beam on the corresponding horizontal beam respectively;
One clock gauge, described clock gauge are installed on the central point of described tripod, and the sounding rod of clock gauge is parallel with pedal line, and the lower end of sounding rod is provided with a measuring head.
In a kind of preferred embodiment of the present utility model, described screw rod leg is closely-pitched screw rod leg.
Owing to having adopted technical scheme as above, the utility model adopts screw rod to pass positioning screw hole on the horizontal beam to make leg, horizontal beam can be along screw rod leg height up and down, and the positioning screw hole that screw rod passes diverse location can play the effect of regulating span, make the utility model can be adaptive with the sample of various different sizes, possess versatility, and use clock gauge as testing tool, improved the accuracy of test.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
