Abstract
The present invention relates to a kind of levelling technique of non-horizontal track vehicle body, car body is set to be in horizontality indirectly by leveling unit.The leveling unit is adjusted to horizontality first with the regulating bolt and frame level of leveling unit, then on the basis of the device, using the empty spring position at four angles of tape measure car body with respect to the device distance, and balanced adjustment is highly carried out using four angles of jack pair car body, realize that car body is levelling.The levelling technique of the present invention is easily achieved, and homework precision is high, and operation intensity is low, will be used widely in auto body repair operation.
Description
Technical field
The present invention relates to the levelling technique of non-horizontal track vehicle body, belong to rail truck manufacturing process technology field.
Background technology
Before railway bus body steel structure's reconditioning work, car body must be made to be in horizontality（I.e. levelling operation）, so as to according to
Benchmark, completes every repair assignment accordingly, such as carries out digging, cuts and change and position assembling, especially carries out similar toilet waste collector flap seat
The positioning assembling operation of crossbeam（Each flap seat requirement for horizontality is higher）.But general auto body repair platform position only has common rail, does not match somebody with somebody
The track after levelling is put, i.e., without car body levelling benchmark.
The content of the invention
The technical problems to be solved by the invention are to overcome the disadvantages mentioned above of prior art there is provided a kind of non-horizontal track
The levelling technique of car body.
In order to solve the above technical problems, the levelling technique of non-horizontal track vehicle body that the present invention is provided, it is characterised in that：Borrow
A kind of leveling unit is helped to realize, the flatness that the leveling unit includes plane on square steel, the square steel is not more than 0.3mm；Side
The lower surface at steel two ends at track cooperation with being respectively arranged reference block, and the flatness of reference block lower plane is not more than 0.3mm, wherein
Two levelness regulating bolts symmetrically are vertically arranged on the reference block of square steel first end, the end of square steel second has been vertically arranged one
Difference of height regulating bolt positioned at square steel transverse center position；The levelling processing step is as follows：
1st step, by leveling unit on the track being positioned over below the empty spring mounting surface of car body, make the first reference block, the
Two reference blocks respectively fall in orbit plane；
Frame level is placed in 2nd step, the square steel upper surface of leveling unit；
3rd step, by adjusting difference of height regulating bolt, the square steel two ends of leveling unit is adjusted in an elevation plane
It is interior；
4th step, the levelness by plane on horizontal adjustment bolt regulation square steel, make plane holding level on square steel；
5th step, the empty spring mounting surface of measurement car body to distance flat on square steel；
6th step, using four angles of jack pair car body balanced adjustment is highly carried out, make the empty spring mounting surfaces of four car bodies to just
Flat distance is equal on steel, so as to realize that car body is levelling.
The present invention also has following improvement：
1st, the reference block is fixedly welded on the lower surface at square steel two ends.
2nd, the reference block of the square steel first end offers 2 screws, and the levelness regulating bolt is screwed into the screw.
3rd, the reference block at the end of square steel second offers 1 screw, and the levelness regulating bolt head passes through square steel
It is screwed into behind second end in the screw.
The present invention makes car body be in horizontality indirectly by leveling unit.First with leveling unit regulating bolt and
Frame level adjusts the leveling unit to horizontality, then on the basis of the device, utilizes tape measure car body four
The empty spring position at angle highly carries out balanced adjustment with respect to the device distance, and using four angles of jack pair car body, realizes car body
It is levelling.The levelling technique of the present invention is easily achieved, and homework precision is high, and operation intensity is low, will be obtained in auto body repair operation extensively
Using.
