Abstract
The invention provides a method for using magnetic suspension needles to perform secondary tank lineation and solves the problem that the existing pneumatic tip lineation method affects secondary lineation accuracy. The method includes: pre-drawing a central line of a secondary lineation body on the secondary lineation body; using the bottom generatrix pre-drawn at the bottom of a tank as the primary line; hanging the tank to place on the roller rack of the secondary lineation body, and rotating the roller rack to allow the primary line to be basically located right under the tank; hanging one magnetic suspension needle at each of the two ends of the primary line, rotating the tank to allow the vertical projection of the magnetic suspension needle at one end to coincide with the central line of the secondary lineation body, and stopping rotating the tank; measuring the vertical distance A between the vertical projection of the magnetic suspension needle on the other end and the central line of the secondary lineation body, and re-drawing the bottom generatrix of the tank to serve as the secondary line according to the modification value A/2. The method is simple in process and procedure and cost saving, and the influence of deformation of the long-term-used secondary lineation body on the central line is avoided.
Description
Technical field
The present invention relates to the manufacture field of tank body of tank car, be specifically related to a kind of method of utilizing magnetcisuspension pin to carry out the line of tank body secondary.
Background technology
At present, in China railways tank car tank body manufacture process, the pneumatic top method of scoring of the general employing of secondary line, its principle is as shown in Fig. 1 a, Fig. 1 b, Fig. 1 c.Tank body secondary line tire is comprised of a secondary roller frame and two, two ends reservoir, and the center of reservoir is located on the longitudinal centre line of two turning rolls, and reservoir top is positioned on the center line (datum line) of tank body secondary line tire.
During work, tested tank body is winched on the turning rolls of secondary line tire with overhead traveling crane, start reservoir rise top, it is top that rotation tank body first makes the pre-bottom bus (primary line) of drawing of one end aim at reservoir, and tank body now stops operating; Measure the top deviate A with bottom bus (primary line) of other end reservoir, get half A/2 of this value as the foundation of revising tank base bus (primary line), finally according to correction value A/2, again mark the bottom bus of tank body, i.e. secondary line.
The shortcoming of prior art: because two reservoirs of tank body secondary line tire and the pedestal of turning rolls are welding as one, in tank body landing process, there will be impact, cause reservoir pedestal bias or skew, long-term use, can cause the crooked phenomenon of the meeting top appearance of reservoir, affect the accuracy of secondary line, as shown in Figure 2.
Summary of the invention
The object of the invention is: a kind of method of utilizing magnetcisuspension pin to carry out the line of tank body secondary is provided, solves the reservoir pedestal of existing pneumatic top method of scoring because generation bias or skew are impacted in tank body landing, affect the technical problem of the accuracy of secondary line.
Technical solution of the present invention is:
A method of utilizing magnetcisuspension pin to carry out the line of tank body secondary, its special character is: comprise the following steps:
1) make secondary line tire, on secondary line tire, mark in advance the center line of secondary line tire; Using the bottom bus that marks in advance in tank base as primary line;
2) tank body is hung on the turning rolls of secondary line tire, rotation roller frame, makes the primary line of tank body substantially be positioned under tank body;
3) a magnetcisuspension pin is hung respectively at the two ends of the primary line marking in advance in step 1), and magnetcisuspension pin one end is adsorbed on tank body and is the state of naturally drooping;
4) rotate tank body, first make the vertical projection of the magnetcisuspension pin of one end overlap with secondary line tire center line, tank body now stops operating;
5) vertical projection of the magnetcisuspension pin of the measurement other end, apart from the vertical range A of secondary line tire center line, is got A/2 as the foundation of revising tank body primary line;
6) according to correction value A/2, again mark the bottom bus of tank body, as secondary line.
Advantage of the present invention is:
(1) by the comparison of the magnetcisuspension pin that suspends in midair below tank body of tank car and secondary line tire center line (datum line), complete the secondary line of tank body, guarantee the line quality of tank base bus (longitudinal centre line secondary line), meet the requirement to bus precision in tank body manufacture process.
(2) technique is simple, has omitted and on the longitudinal centre line of turning rolls, has welded the top step of reservoir, saves operation and cost.
(3) secondary line tire center line is not connected with secondary line tire, and secondary line tire center line can be drawn on the ground, has avoided the distortion of long-term use secondary line tire for the impact of center line.

The specific embodiment
The technical characterstic of maximum of the present invention is the magnetcisuspension pin using at tank body two ends, and it is core of the present invention place, and it, has and hang rapidly according to magnetic-adsorption below tank body, accurate positioning, the feature such as easy to operate.
Utilize magnetcisuspension pin to carry out a method for tank body secondary line, comprise the following steps:
1) make secondary line tire, on secondary line tire, mark in advance the center line 6 of secondary line tire; Using the tank base bus 5 that marks in advance in tank base as primary line;
2) tank body 1 is hung on the turning rolls of secondary line tire, rotation roller frame 2, makes the primary line of tank body substantially be positioned under tank body;
3) a magnetcisuspension pin 3 is hung respectively at the two ends of the primary line marking in advance in step 1), and magnetcisuspension pin one end is adsorbed on tank body and is the state of naturally drooping;
4) rotate tank body, first make the vertical projection of the magnetcisuspension pin of one end overlap with secondary line tire center line, tank body now stops operating;
5) vertical projection of the magnetcisuspension pin of the measurement other end, apart from the vertical range A of secondary line tire center line, is got A/2 as the foundation of revising tank body primary line;
6) according to correction value A/2, again mark the bottom bus of tank body, as secondary line.
Existing method need to be top at the secondary tire center line welding reservoir of ruling, need to guarantee the perpendicularity of reservoir top 4, complex process, cost is high, tank body landing is impacted eccentric or skew is occurred, and also can affect the accuracy of secondary line, and the present invention has omitted this step, not only save operation, can also improve the accuracy of secondary line.The center line (datum line) 6 of secondary line tire of the present invention is drawn on turning rolls pedestal, can effectively prevent from causing secondary line tire center line (datum line) to occur the situation of skew because of pneumatic top long-term use distortion.
The present invention's magnetcisuspension pin used is an elongated needle, and after tank body hangs on the turning rolls of secondary line tire, the length of magnetcisuspension pin can not surpass bottom bus apart from the vertical range of secondary line tire.
Key problem in technology point of the present invention is used magnetcisuspension pin, utilize the magnetic of magnetcisuspension pin and be hung on tank body lower part, the deviation occurring for detection of tank body bus (primary line), and then find out difference correction, finally mark revised tank base bus 7, be secondary line, this method is applicable to various forms of tank body of tank car secondary line.
