Abstract
The utility model discloses a big vehicle positioning wheelspan gauge which includes a gauge rod, a pointer, and a magnetic sucker. One end of the gauge rod is provided with the magnetic sucker. The pointer is provided with a positioning ring. The gauge rod is movably sleeved with the positioning ring. The pointer slides along the gauge rod. The gauge rod is provided with scales. The big vehicle positioning wheelspan gauge improves the measurement precision of a position indicator, and avoids the measurement error caused by the condition that the axle center lines of a multi-axle vehicle are not aligned. The design is humanized, and the big vehicle positioning wheelspan gauge can be better used in combination with a big vehicle four-wheel position indicator, and makes the most of the four-wheel position indicator.
Description
Technical field
The utility model relates to the vehicle detection technical field, particularly a kind of cart locating wheel carpenters square.
Background technology
Because of in vast Automobile Service station, four-wheel detection and localization maintenance automobile is necessary, but because in testing process, because multi-wheeler is travelling when especially turning to, different moving axially can take place in a plurality of axletrees, cause four-wheel position finder in the process that detects, to be difficult to operation, or testing result has phenomenon generations such as deviation, used the above problem of wheel carpenters square just to be readily solved just.
The automotive wheels carpenters square is that equipment was used for measuring between the wheel wheel center distance in order to a kind of checkout equipment of subsequent detection step before the vehicle front locator value detected during the preparatory stage.At present known product generally adopts the optoelectronic scanning mode, its by in the place ahead of vehicle to wheel transversal scanning measure deflecting roller wheel center distance.But detect because the mode of optoelectronic scanning needs to stop in test process, so its process need expends the regular hour and then it is long to make whole front alignment value detect the station testing process, is unfavorable for detecting the requirement of streamline efficient quick.For a change this situation our factory has at first developed the photosensitive formula wheel of product carpenters square, its method of work is: the light activated switch that a row evenly arranges is set, when wheel when light activated switch passes through, trigger corresponding photosensitive switch motion, control circuit changes into the quick switch motion situation of change of this process the numerical value of deflecting roller wheel centre distance.Photosensitive formula wheel carpenters square has solved the problem of stopping and detecting, but owing to be that roller carpenters square light on every side guarantees operate as normal, light activated element just can't operate as normal when light is dark.Therefore must equip the floor light light source.Through using its still old a lot of problems: the machining precision height, the light-receiving window of easy-maintaining, light activated switch is easy to wear and be subjected to very easily that spot such as dust greasy dirt is polluted, water proofing property requires high.
In view of this, those skilled in the art provide a kind of cart locating wheel carpenters square at the problems referred to above.
The utility model content
The utility model provides a kind of cart locating wheel carpenters square, has overcome the difficulty of prior art, to reach the measuring accuracy that improves orientator, avoids the purpose of the measuring error that do not cause because of each axletree center line of multiple-axle vehicle on a line.
The utility model adopts following technical scheme:
The utility model provides a kind of cart locating wheel carpenters square, comprise chi bar, pointer and magnetic suction disc, one end of described chi bar is provided with described magnetic suction disc, described pointer is provided with a locating ring, the described locating ring of pivot bush unit on the described chi bar, described pointer slides along described chi bar, and described chi bar is provided with scale.
Preferably, the vertical described pointer in the axle center of described locating ring.
Preferably, described locating ring is arranged on the middle part of described pointer.
Owing to adopted above-mentioned technology, compared with prior art, cart locating wheel carpenters square of the present utility model has improved the measuring accuracy of orientator, avoid the measuring error that on a line, do not cause because of each axletree center line of multiple-axle vehicle, its humanization designing, and use with cart four-wheel position finder better fit, make four-wheel position finder bring into play the effect of its maximum.
Further specify the utility model below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of cart locating wheel carpenters square of the present utility model.
Reference numeral
1 is the chi bar;
2 is pointer;
3 is magnetic suction disc;
4 is locating ring.
Embodiment
Introduce a kind of specific embodiment of the present utility model below by Fig. 1.
Embodiment 1
As shown in Figure 1, a kind of cart locating wheel carpenters square of the present utility model, comprise chi bar 1, pointer 2 and magnetic suction disc 3, one end of described chi bar 1 is provided with described magnetic suction disc 3, described pointer 2 is provided with a locating ring 4, the described locating ring 4 of pivot bush unit on the described chi bar 1, described pointer 2 slides along described chi bar 1, and described chi bar 1 is provided with scale.The vertical described pointer 2 in the axle center of described locating ring 4.Described locating ring 4 is arranged on the middle part of described pointer 2.
Cart locating wheel carpenters square of the present utility model is when actual measurement, magnetic suction disc 3 is used for fixing the wheel carpenters square and automobile frame closely connects, chi bar 1 plays a supportive role and reads measurement data, and pointer 2 is adjacent to the cylindrical and the cooperation of chi bar of Automobile steel ring and reads measurement data.The utility model can be used for measuring the size that moves axially of common cargo vehicle or Trailer car shaft.
In summary, owing to adopted above-mentioned technology, cart locating wheel carpenters square of the present utility model has improved the measuring accuracy of orientator, avoid the measuring error that on a line, do not cause because of each axletree center line of multiple-axle vehicle, its humanization designing, and use with cart four-wheel position finder better fit, make four-wheel position finder bring into play the effect of its maximum.
Above-described embodiment only is used to illustrate technological thought of the present utility model and characteristics, its purpose is to make those skilled in the art can understand content of the present utility model and implements according to this, can not only limit claim of the present utility model with present embodiment, be all equal variation or modifications of doing according to the spirit that the utility model disclosed, still drop in the claim of the present utility model.
