Abstract
The invention discloses a linearity detector comprising equal-height blocks, an upper flat plate, upper equal-height strips, a lower flat plate and lower equal-height strips. The upper equal-height strips and the lower equal-height strips are respectively fixed to the upper flat plate and the lower flat plate through countersunk bolts, the upper flat plate and the lower flat plate are fixed together by the equal-height blocks, and gaps for linearity detection are respectively formed between the upper equal-height strips and the lower equal-height strips. The linearity detector is simple in structure and convenient and reliable to detect, and guarantees product quality, improves work efficiency and reduces production cost. By changing the equal-height blocks of different height, the linearity detector can also be applied to detecting round pipes/rods of different specifications, and accordingly has high flexibility.
Description
Technical field
The present invention relates to a kind of linearity testing apparatus, particularly a kind of linearity testing apparatus that is applicable to round tube/bar, belongs to mechanical automation field.
Background technology
In commercial production, especially weld round tubing and bar after round tubing, bar and material heat treatment, easily occur axial flexural deformation, and this distortion there is very large randomness, to directly cause product linearity cannot reach technical requirement, occur the problem of unstable product quality.In order to address this problem, in actual production, conventionally adopt the artificial x ray fluoroscopy x method of crossing, product is carried out to detection one by one, realize the separated of certified products and unacceptable product.Because the turnout of welding tubing is very large, so that testing becomes is very heavy, and be a kind of work of fixedly action of repetition, especially easily cause personnel tired and cause erroneous judgement.Direct result is exactly unstable product quality, and defect ware increases, and production efficiency declines, and labour intensity is very high, has increased the operation cost of enterprise.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of round tube/bar linearity testing apparatus that is applicable to, guarantee to detect the linearity requirement that qualified material can reach product technology standard completely.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of linearity testing apparatus, comprise: isometry block, upper flat plate, upper contour, lower flat board, lower contour, described contour and lower contour is separately fixed on upper flat plate and lower flat board by dormant bolt, described isometry block is fixed together upper flat plate and lower flat board, has formed the gap for detection of straight lines degree between upper contour and lower contour.
Aforementioned isometry block is 4, is fixed on symmetrically upper flat plate and lower dull and stereotyped two ends.
Aforementioned upper flat plate, upper contour, lower flat board, lower contour measuring instrument steel or T10A tool steel that all adopts after Q-tempering hardness to reach HRC58-62 are made, and carry out by grinding machine processing, guaranteeing flatness and the depth of parallelism again after Ageing Treatment.
Aforementioned dormant bolt is used anti-back glue fastening.
Milled processed is all passed through in the installation site of aforementioned 4 isometry blocks, upper contour, lower contour, to guarantee flatness and the depth of parallelism.
Height tolerance≤0.005 of aforementioned 4 isometry blocks, to guarantee the depth of parallelism of upper flat plate and lower flat board.
Aforementioned contour and lower contour is a plurality of, is symmetricly set in equally spacedly on upper flat plate and lower flat board.
Usefulness of the present invention is: linearity testing apparatus of the present invention, and simple in structure, easy to detect reliable, guaranteed product quality, improved work efficiency, reduced production cost; By changing the isometry block of differing heights, this pick-up unit can also be applicable to the detection of the round tube/bar of plurality of specifications, and dirigibility is high.

The implication of Reference numeral in figure: 1, isometry block, 2, upper flat plate, 3, upper contour, 4, lower flat board, 5, lower contour, 6, pipe.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Referring to Fig. 1 to Fig. 3, a kind of linearity testing apparatus of the present invention, comprising: isometry block 1, upper flat plate 2, upper contour 3, lower dull and stereotyped 4, lower contour 5.Wherein, isometry block 1 is preferably 4, thereby being fixed on symmetrically respectively upper flat plate 2 and lower dull and stereotyped 4 two ends is fixed together upper flat plate 2 and lower dull and stereotyped 4, the position of isometry block 1 is installed on upper flat plate 2 and lower dull and stereotyped 4 and all passes through milled processed, to guarantee flatness and the depth of parallelism, further, height tolerance≤0.005 of 4 isometry blocks 1, and then the whole depth of parallelism of assurance upper flat plate 2 and lower dull and stereotyped 4.It should be noted that, isometry block 1 can be changed, and the isometry block 1 of different-thickness can, for detecting the material of different size, improve the scope of application of this pick-up unit.
As a modification of the present invention, upper flat plate 2, upper contour 3, lower dull and stereotyped 4, lower contour 5 measuring instrument steel or T10A tool steel that all adopts after Q-tempering hardness to reach HRC58-62 are made, carry out by grinding machine processing, guaranteeing flatness and the depth of parallelism again after Ageing Treatment, with anti-buckling deformation.
Detection method is as follows: pick-up unit is tilted to proper angle, as Fig. 2, pipe 6/ bar rolls and starts to enter contour 3 and lower contour 5 gap forming, if the linearity of material meets technical requirement, to under the Action of Gravity Field of self, roll by pick-up unit, as shown in Figure 3.During use, should on pick-up unit, be coated with rust preventive oil, avoiding getting rusty affects precision, should note keeping clean simultaneously.By this pick-up unit can be efficiently, whether the linearity of test material meets technical requirement quickly and accurately, has greatly improved production efficiency, has guaranteed the quality of product.
More than show and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
