Abstract
The utility model provides a kind of car body centering apparatus of rail vehicle built-in fitting installation, including fluted body chi body, a connecting shaft is equipped with the middle part of the fluted body chi body, described connecting shaft one end connects drive gear, other end connection driving handle, the drive gear engage measurement bar.Centering apparatus of the present utility model is extension type, measurement bar both ends synchronization telescope, and ensures that the center line of measurement bar is constant；Measure boom end T-type structure can be limited the problem for preventing measurement bar from tiltedly putting, solving the bad determination of vehicle body size datum center line in rail vehicle actual production, good effect is achieved in actual production.
Description
Technical field
It the utility model is related to vehicular field, and in particular to a kind of car body of rail vehicle built-in fitting installation looks for middle dress
Put.
Background technology
For the built-in fitting of rail vehicle, in design be all the center line using car body as size datum, and in work
When skill converts, because 4mm tolerance in itself be present in car body（Actual often more than 4mm）, the bad conversion variation of size datum, therefore
Built-in fitting must be on the basis of car body center line when installing.But the difficulty in vehicle body is looked for car body is larger, does not also have
Special tool(s), typically measured with tape measure, measurement effect is not ideal, and then has influence on the integral installation effect of vehicle built-in fitting
Fruit.
Utility model content
Technical problems to be solved：The purpose of this utility model is to provide a kind of car body of rail vehicle built-in fitting installation
Centering apparatus, it is therefore intended that overcome the difficulty in being looked in rail vehicle body big, measurement result is inaccurate, and accuracy is too low to ask
Topic.
Technical scheme：A kind of car body centering apparatus of rail vehicle built-in fitting installation, including fluted body chi body, it is described recessed
A connecting shaft is equipped with the middle part of groove profile chi body, described connecting shaft one end connects drive gear, other end connection driving handle, the driving
Gear engages measurement bar.
Further, the car body centering apparatus of described a kind of rail vehicle built-in fitting installation, the measurement bar are T
Type, and quantity is a pair.
Further, the car body centering apparatus of described a kind of rail vehicle built-in fitting installation, the drive gear and
Measurement bar is located in the groove of fluted body chi body.
Further, the car body centering apparatus of described a kind of rail vehicle built-in fitting installation, the measurement bar it is T-shaped
Structure is located at the device both sides respectively.
Further, the car body centering apparatus of described a kind of rail vehicle built-in fitting installation, if the measurement bar with
Dry driven gear is meshed.
Beneficial effect：Car body centering apparatus of the present utility model possesses advantages below：
（1）Centering apparatus is extension type in car body
Manually rotating handles drives drive gear to rotate, then is converted rotational motion into directly by rack-and-pinion combination
Line moves, it is achieved thereby that the expanding-contracting action of measurement bar；
（2）Measurement bar both ends can synchronization telescope
One gear drives the measurement bar of two rack structures simultaneously, ensure that two measurement bar synchronous same-speed motions；Two
The layout that individual measurement bar is relative and puts, ensure that two measurement bars can move in the opposite direction；
（3）Measurement boom end is designed to T-type structure
One end that measurement bar contacts with car body is designed to T-type structure, be allowed to measurement bar vertical arrangement, only need to be by T junction
Structure is attached on vehicle body side wall, so that it may ensure it is vertical between measurement bar and vehicle body side wall, so as to improve the precision of measurement.
The utility model solves the problem of the bad determination of vehicle body size datum center line in rail vehicle actual production,
Good effect is achieved in actual production.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.Specific embodiment of the present utility model is shown in detail by following examples and its accompanying drawing.

Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in detail.
Referring to Fig. 1-4, a kind of car body centering apparatus of rail vehicle built-in fitting installation, including fluted body chi body 4, groove
The middle part of type chi body 4 is equipped with a connecting shaft, connecting shaft one end connection drive gear 1, and other end connection drives handle 5, and drive gear 1 is nibbled
Measurement bar 3 is closed, measurement bar 3 is also meshed with some driven gears 2, and drive gear 1 and measurement bar 3 are located at fluted body chi body 4
In groove, drive drive gear 1 to rotate by rotation driving handle 5, then converted rotational motion into by rack-and-pinion combination
Linear motion, it is achieved thereby that the expanding-contracting action of measurement bar.
Further, described measurement bar 3 is T-shaped, and quantity is a pair, and the T-type structure of measurement bar 3 is located at the dress respectively
Put both sides, one end that measurement bar 3 contacts with car body be designed to T-type structure, be allowed to measurement bar vertical arrangement, only need will be T-shaped
Structure is attached on vehicle body side wall, so that it may ensure it is vertical between measurement bar 3 and vehicle body side wall, so as to improve the precision of measurement；One
Individual drive gear 1 drives the measurement bar 3 of two rack structures simultaneously, ensure that two synchronous same-speed of measurement bar 3 motions；Two surveys
The layout that gauge rod 3 is relative and puts, ensure that two measurement bars 3 can move in the opposite direction.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
