Abstract

A combined target in an automatic measuring system of a bullet train body comprises a base placement part and an observation aiming part. Notches are formed in the two sides of a longitudinal center line of the base placement part respectively, two protrusions are machined on the side face, corresponding to the notches of the base placement part, of the observation aiming part to be matched with the notches formed in the two sides of the center line of the base placement part, the two protrusions are used for fixing and ensuring that the base placement part and the observation aiming part are in an orthogonal state all the time, a notch is formed in the center of the longitudinal center line of the base placement part to be matched with a rectangular cone on the center of one side face of the observation aiming part, and the rectangular cone is used for accurately locating the position of a point to be measured. The combined target in the automatic measuring system of the bullet train body is simple in design, easy to arrange, convenient and rapid to use and capable of being reused.

Description

Combined type target in a kind of Motor train unit body automatic measurement system
Technical field
The present invention relates to vehicle body of railway vehicle detection technique, especially relates to combined type measurement point target in a kind of vehicle body of railway vehicle automated detection system.
Background technology
Railroad car bodywork generally can select carbon steel, stainless steel or aluminium alloy as the material of body construction, due to aluminium alloy have lightweight, corrosion-resistant, flat appearance degree is good and be easy to manufacture the advantage such as complicated curved surface car body attractive in appearance, has become the main flow that current motor train unit body manufactures.In actual manufacture process, the welding difficulty of aluminum alloy bodywork is far longer than common steel weldering, and be a comprehensive and production technology for complexity, a large amount of weld jobs must cause the deviation existed between car body Theoretical Design value and practical set value in various degree.The leakproofness, bus body strength, body gravity position, security of operation etc. of these deviations on train in high-speed cruising all have very important impact.Therefore, the Real-time Obtaining of deviation and quantitative test between theoretical value and actual value, be not only and detect the whether qualified important criterion of car body assembling, or the important evidence instructing assemble welding to adjust in car body manufacture process.
EMU car body automated detection system mainly applies the method for accurate commercial measurement, in commercial measurement, usually uses prism or reflector plate as the target of measurement point.In the automatic testing process of Motor train unit body, total powerstation, according to the information pre-set, Automatic-searching, sights target, and measures.But because Motor train unit body overall dimensions is comparatively large, composing room's compact in design, can be comparatively large for the place limitation of erection total powerstation, and common target cannot be used to carry out effective laying of measurement point.Main existence two reasons: one is that car body size is comparatively large, car body cannot set up prism, even if adopt the mode of human assistance to set up prism by force, still there is the problem of different observation cycle check point positions inconsequent; Two is that car body making-up shop is very compact, and various rigging equipment occupies a large amount of spaces, and research station can only be erected at the two ends of car body, therefore adopts reflector plate as check point target, there is total powerstation and cannot observe and the problem obtaining correct data.
Summary of the invention
The object of this invention is to provide a kind of combined type measurement point target frock, this target can be laid under, the specific condition such as testing staff not easily arrives, common target cannot be suitable for poor at vehicle body observation condition, achieves the automatic measurement of check point in Motor train unit body detection system.
For achieving the above object, the invention provides combined type target in a kind of Motor train unit body automatic measurement system, it is characterized in that: comprise pedestal placement portion and observation alidade, a breach is respectively opened on longitudinal centre line both sides, pedestal placement portion, observation face, the alidade side gap position corresponded on pedestal placement portion is processed with two projections and matches with the breach on center line both sides, pedestal placement portion, for fixing and guaranteeing that pedestal placement portion is in orthogonal with observation alidade all the time, a breach is also opened in longitudinal centre line center, pedestal placement portion, match with the rectangular cone of observation center, alidade one side, rectangular cone is used for the position of accurately location point to be measured.
Side, pedestal placement portion has two circular ports, is more firmly fixed observer alidade.
Simplicity of design of the present invention, is easy to arrange, easy to use, can reuse.Pedestal placement portion can, according to the material of attachment or other requirement, select screw or glue rifle to be fixed.And after surveying work completes, target can be reclaimed and re-use.The replacement laying precision of measurement point position is high, is easy to reset.Because pedestal placement portion is separated with observation alidade, therefore first the conical head of observation alidade accurately can be pointed to the position of tested measuring point, and then carry out the fixing of pedestal placement portion, thus achieve the self-consistentency that measurement point resets laying, achieve the automatic measurement of check point in Motor train unit body detection system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of pedestal placement portion in the present invention;
Fig. 3 is the structural representation observing alidade in the present invention.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the present invention includes pedestal placement portion 1 and observation alidade 2, a breach A is respectively opened on longitudinal centre line both sides, pedestal placement portion, B, the gap position that observation face, alidade side corresponds on pedestal placement portion is processed with two protruding a, b matches with the breach on center line both sides, pedestal placement portion, for fixing and guaranteeing that pedestal placement portion is in orthogonal with observation alidade all the time, a breach C is also opened in longitudinal centre line center, pedestal placement portion, match with the rectangular cone c of observation center, alidade one side, rectangular cone is used for the position of accurately location point to be measured.Wherein the width of centrum is equal with the width of circumferential notch C; Conical nose ensure that on the one hand to have accurate conversion relation between measuring point to be checked on car body and " target crosshair ", and another aspect also ensure that the self-consistentency sex chromosome mosaicism of same check point in the different measuring cycle.Side, pedestal placement portion has two circular ports D, E, is more firmly fixed observer alidade.

Claims (2)
