Abstract
The invention provides a pipe or bar straightness detecting ruler. The pipe or bar straightness detecting ruler is structurally formed by a right angle detecting table and a detecting sliding block, wherein scale marks parallel to the perpendicular face of the detecting table are marked on the horizontal plane of the right angle detecting table to serve as detection standard lines for detecting whether a pipe or a bar is qualified or not. When straightness is detected, the pipe or the bar is flatly placed on the horizontal plane of the right angle detecting table, the detecting sliding block is arranged at the position, on the outer side of the pipe or the bar, of the horizontal plane and pushes the pipe or the bar to completely and naturally attach to the perpendicular face of the right angle detecting table in a pressure free mode, and whether the pipe or the bar is qualified in the straightness or not is judged according to the conditions of the contact faces of the detecting sliding block and the pipe or the bar on the inner portion or the outer portion of the scale marks. According to the design scheme of the pipe or bar straightness detecting ruler, the problem that large companies detect the straightness of pipes and bars by relying on large horizontal planes and the beating degrees of micrometers and are troubled for a long period is solved, the problem that middle and small-sized enterprises cannot detect the straightness of the pipes or bars is also solved, and the pipe or bar straightness detecting ruler is a straightness detecting tool which is simple in design, fast, efficient and reliable in performance.
Description
Technical field
The present invention relates to a kind of pipe, the straight degree of rod detection ruler, relate to specifically a kind of examinaing method of material section bar manufacture field, is mainly the invention achievement that tubing and bar product are directly spent detection.
Background technology
Both at home and abroad for tubulose or bar-shaped section bar, especially metal material pipe or excellent class section bar are measured never special surveying instrument and the equipment of straight degree, and general detection method for judging in the straight degree margin tolerance that whether flexibility is requiring in other words of pipe or rod by the beating degree of clock gauge measuring tube or rod on the large plane casting platform of level.The defect of this detection method comprises: one, detect the consumption power of taking a lot of work, completely by testing staff's perceptual result, inefficiency, testing result error is large, precision is low; Two, owing to detecting beating degree, to rely on pipe or excellent maximum raised points or peak to calculate, therefore peak is because the Action of Gravity Field of pipe or rod self is downward, reduced the beating degree scope of pipe or rod, testing result is not actual numerical value completely, causes the substandard products to enter the error-detecting of certified products.Also just because of the deficiency of pipe or the straight degree of rod detection method, cause domestic enterprise, especially medium-sized and small enterprises are difficult to produce the pipe of high-precision end, excellent section bar.
Summary of the invention
Object of the present invention, be to provide a kind of pipe, the straight degree of rod detection ruler, the design of this straight degree detection ruler, solved the qualification determination instrument that tubing in section bar or bar are directly spent, efficiency and precision that pipe, excellent class section bar detect have been improved, for promoting enterprise provides detection method and instrument reliably to high added value, high-precision end pipe, excellent product transformation.
The object of the present invention is achieved like this, and one, according to axially longer a kind of straight degree detection ruler of feature shape design of pipe, rod; Two, according to detector tube or the straight degree of rod itself, be exactly the distance principle farthest, two phase tangent planes parallel with the face of cylinder apart that detects this class right cylinder section bar, detection ruler to have two parallel planes stable with one, with two planes that parallel plane is vertical, it is less important, and whether qualified have scale datum line to judge, by straight degree detection ruler, accurately judge so the straight degree of tubing or bar, be flexural deformation whether in the margin tolerance of regulation, whether qualified.
Pipe, the design considerations of the straight degree of rod detection ruler is simple, reliably, efficiently, the principle of saving, by right angle monitor station and detection slide block two parts, formed, wherein monitor station surface level in right angle indicates maximum upper limit size scale line according to nominal diameter and the maximum plus tolerance of the pipe that will detect or rod, during measurement, pipe or excellent section bar natural horizontal are placed on the surface level of scale mark and vertical detection platform, the obvious direction of crooked protrusion or warpage is towards detecting slide block, with detect slide block along monitor station surface level by pipe or rod gently near the vertical plane of right angle detection platform, until pipe or rod are completely, nature, without pressure by being attached to the vertical plane of right angle monitor station, whether qualified at the inside and outside situation judgement pipe of scale mark and the straight degree of rod according to detecting slide block and pipe or excellent surface of contact.
Embodiment
Below by accompanying drawing explanation and embodiment, the invention will be further described.
Fig. 1 is a kind of pipe of the present invention, the straight degree of rod detection ruler design proposal
In figure: 1-right angle monitor station; 2-detects slide block; 3-detects scale mark.
Embodiment 1. does and detects Φ 20 * 1 * 2000 copper pipes, and during copper pipe pipe range 2000mm, straight degree is directly spent detection ruler at 3mm with interior acceptable.With organic glass, be processed into rectangular right angle monitor station and detect slide block, wherein the surface level thickness of right angle monitor station is 10mm, vertical plane thickness is 10mm, the surface level full-size of right angle monitor station is wide is 80mm, vertical plane full-size height is 50mm, monitor station surface level and vertical plane are 90 ° ± 0.1 °, detect director 2200mm, detect slide block and be of a size of 20 * 20 * 200, on right angle detection platform surface level, do parallel with right angle monitor station vertical plane, apart from the linear mark of vertical plane 23mm for detecting scale mark.Like this, one can be fast, efficient, high precision detects straight degree and just completed with interior acceptable Φ 20 * 1 * 2000 brass pipe straightness detection rulers at 3mm.
Embodiment 2. does and detects Φ 100 ± 1 * 5000 aluminium bars, and during the long 5000mm of aluminium bar, straight degree is directly spent detection ruler at 10mm with interior acceptable.Cylinder iron plate welding is processed into rectangular right angle monitor station and detects slide block, wherein the surface level thickness of right angle monitor station is 20mm, vertical plane thickness is 50mm, the surface level full-size of right angle monitor station is wide is 300mm, vertical plane full-size height is 150mm, monitor station surface level and vertical plane are 90 ° ± 0.5 °, detect director 5500mm, detect slide block and be of a size of 100 * 100 * 1000, on right angle detection platform surface level, do parallel with right angle monitor station vertical plane, apart from the linear mark of vertical plane 111mm for detecting scale mark.Like this, one can be fast, efficient, high precision detects straight degree and at 10mm, with interior acceptable 100 ± 1 * 5000 aluminium bars, directly spends detection ruler and just completed.
