Abstract
The invention relates to a method for measuring the parallelism of a roller way through a theodolite. The method includes the steps that a production line is measured and set, and an auxiliary longitudinal center line is installed; the theodolite is erected at the measurement position of the auxiliary longitudinal center line, and an auxiliary transverse center line parallel to the center of the measured roller way is determined through the 90-degree angle rotating function of the theodolite; the theodolite is used in cooperation with a precise try square so that the distance between the roller side face measurement positions at the two ends of the roller way and the auxiliary transverse center line can be measured and a difference value between the roller side face measurement positions and the auxiliary transverse center line can be measured. Compared with a traditional roller way parallelism measurement method (a swing arm method), the method has the advantages that operation is easy and convenient, the method is not affected by a small and narrow space of a measurement area, a swing arm does not need to be manufactured, and data measurement is visual and accurate.
Description
Technical field
The invention belongs to technical field, particularly relate to a kind of method adopting transit to carry out the roller-way measurement of paralleism.
Background technology
Roller-way install and adjust in installation is one very general installation procedure, and deflector roll quantity is many, and adjustment consumption for a long time.The swing arm mensuration that we commonly use at present all needs when measuring each time to install swing arm, deflector roll for differential roller footpath also needs the swing arm with making multiple specification, and due to workman, to make the level of swing arm different, often cause the difference of swing arm rigidity, and then cause larger measuring error; Also swing arm method cannot be adopted to carry out the measurement of the roller-way depth of parallelism, as the measurement of paralleism of withdrawal straightening machine inner press roll in some narrow and small device space simultaneously.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of method adopting transit to carry out the roller-way measurement of paralleism, and to solve original measuring method length consuming time, efficiency is low and be difficult to the problem used in little space.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of method adopting transit to carry out the roller-way measurement of paralleism, comprising:
1) longitudinal axis is established in survey: first measure according to equipment Foundations, arrange equipment installation longitudinal centre line A-A, then according to A-A center line, in production line operation side, the parallel lines of the center line A-A of the outer 1.5 ~ 2.5m of distance apparatus for production line are surveyed and establishes assistant longitudinal center line A1-A1;
2) transit is set up: near roller-way side to be measured on assistant longitudinal center line A1-A1, erection transit in the roller-way parallel surface of distance roller-way side 100 ~ 200mm, adjustment transit sight line overlaps with assistant longitudinal center line A1-A1, and then rotate 90 degree, transit, transit sight line is also formed auxiliary cross central line B-B perpendicular to assistant longitudinal center line A1-A1;
3) survey measurements: to coordinate with precision square with transit and measure roller-way two ends and to be positioned on the tangent line of roller-way side and to measure the spacing of position and auxiliary cross central line B-B apart from the roll surface on the two ends polished surface of roller-way center location of equal and try to achieve deviation, if deflector roll two ends spacing deviation is within the scope of installation permissible variation, represent this roller-way depth of parallelism qualified, otherwise then need to carry out roller-way adjustment until deviation is qualified again;
4) computing formula of deviation is asked to be: (wherein X, Y are respectively the measured value at roller-way two ends to R ˊ=︱ X-Y ︱, R ˊ is absolute difference, and permissible variation maximal value R is generally provided by equipment acceptance side or converts according to related specifications requirement and measurement method and draws.As R ˊ≤R, deviation is qualified.)
Beneficial effect
The present invention have easy and simple to handle, do not affect by roller-way measured zone narrow space, without the need to making swing arm, the measurement data intuitively plurality of advantages such as accurate.
Accompanying drawing explanation
Fig. 1 is the total schematic diagram of this transit survey method of the present invention.
Fig. 2 is the partial enlarged drawing of measuring process in the present invention.
Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
Embodiment 1
As shown in Fig. 1 ~ Fig. 2,
1, longitudinal axis is established in survey: first survey according to equipment Foundations and establish equipment in accompanying drawing one to install longitudinal centre line A-A, then according to A-A center line, survey establish assistant longitudinal center line A1-A1 at rational position;
2, transit is set up: as shown in Figure 1, rational position erection transit on assistant longitudinal center line A1-A1, adjustment transit sight line overlaps with assistant longitudinal center line A1-A1, and then rotary angle of 90 DEG, by transit sight line perpendicular to assistant longitudinal center line A1-A1;
3, survey measurements: as shown in Figure 2, to coordinate with precision square with transit and measure appropriate location, roller-way two ends roll surface and measure the spacing of position and auxiliary cross central line and try to achieve deviation, if deflector roll two ends spacing deviation is within the scope of installation permissible variation, represent this roller-way depth of parallelism qualified.Otherwise then need to carry out roller-way adjustment until deviation is qualified again.
