Description
Technical field
It the utility model is related to a kind of in-service vehicle wheel central projection measurement apparatus.
Background technology
Driving is a kind of conventional crane gear of workshop, its by wheel scrolling realization driving in orbit in itself and
Lift by crane the displacement of article.The most common failure in operation day long afterwards of driving a vehicle is to gnaw rail, wheel wear, sideslip and wheel and track deformation
Deng to make judge with safety to operation of the in-service driving under existing working condition, there is provided traffic safety is run and failure is pre-
The accurate wheel data of alert system, it need to generally implement accurately measurement to vehicle wheel diagonal, and vehicle wheel diagonal is surveyed
The premise of amount is positioning wheel center.The neutral positioning generally use Steel Ruler of traditional vehicle wheel is directly measured on vehicle wheel
Center is taken, very big artificial measurement error be present due to being measured with Steel Ruler, up and down once being not measured by position, testing number
According to very large deviation just occurs.And vehicle wheel can all set the protection devices such as limiter mostly so that measurement space is narrow and small, certain
Conventional meanses can not realize the detection at vehicle wheel center in the case of a little.Ultimately resulting in in-service vehicle wheel center generally can not obtain
To being accurately positioned, cause vehicle wheel diagonal not measure, accuracy error the problems such as.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of in-service vehicle wheel central projection measurement apparatus, this
Device conveniently realizes being accurately positioned for in-service vehicle wheel center, improves the cornerwise measurement accuracy of vehicle wheel, is in-service
The operation of driving and safety evaluation provide reliable basis, it is ensured that the safe operation of driving.
In order to solve the above technical problems, the in-service vehicle wheel central projection measurement apparatus of the utility model include measurement seat,
Screw rod, left clamp, right clamp, wire winding pole, coiling, plumb bob and indicating arm, the measurement seat trailing flank is provided with elongated slot, leading flank is set
There is length scale line, for the screw rod in the elongated slot of the measurement seat trailing flank, the left clamp are fixed at the measurement
Seat one end, the right clamp and indicating arm are located at the screw rod by screw thread, rotated with screw rod, and the right clamp are in the measurement
The elongated slot intrinsic displacement of seat trailing flank, the indicating arm is along measurement seat leading flank displacement and indicates the quarter of the right clamp displacement
Degree, the wire winding pole are wound in the wire winding pole located at the measurement seat top surface, the coiling, and the plumb bob is located at the coiling
End.
Further, the present apparatus also includes handle, and the handle is located at described wire winding pole one end and drives wire winding pole to rotate.
Further, the present apparatus also includes laser target, and the laser target hangs down in the coiling and positioned at described
Above ball.
Because the in-service vehicle wheel central projection measurement apparatus of the utility model employs above-mentioned technical proposal, the i.e. present apparatus
Measurement seat trailing flank be provided with elongated slot, leading flank and be provided with length scale line, screw rod is in the elongated slot for measuring seat trailing flank, Zuo Ka
Pincers are fixed at measurement seat one end, and right clamp and indicating arm are located at screw rod by screw thread, rotated with screw rod, and right clamp are in measurement seat
The elongated slot intrinsic displacement of trailing flank, indicating arm is along measurement seat leading flank displacement and indicates the scale of right clamp displacement, and wire winding pole is set
In measurement seat top surface, coiling is wound in wire winding pole, and plumb bob is located at the end of coiling.The present apparatus is conveniently realized in in-service vehicle wheel
The heart is accurately positioned, and improves the cornerwise measurement accuracy of vehicle wheel, and the operation and safety evaluation for in-service driving provide can
By foundation, it is ensured that the safe operation of driving.
Brief description of the drawings
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the in-service vehicle wheel central projection measurement apparatus structural representation of the utility model；
Fig. 2 is Fig. 1 overlook direction schematic diagram.
Embodiment
As depicted in figs. 1 and 2, the in-service vehicle wheel central projection measurement apparatus of the utility model includes measurement seat to embodiment
1st, screw rod 2, left clamp 3, right clamp 4, wire winding pole 5, coiling 6, plumb bob 7 and indicating arm 8, measurement seat 1 trailing flank are provided with length
Groove, leading flank are provided with length scale line 11, and the screw rod 2 is in the elongated slot of measurement seat 1 trailing flank, the left clamp 3
Described measurement seat 1 one end is fixed at, the right clamp 4 and indicating arm 8 are located at the screw rod 2 by screw thread, revolved with screw rod 2
Turn, the right clamp 4 are in the elongated slot intrinsic displacement of measurement seat 1 trailing flank, and the indicating arm 8 is along the measurement leading flank displacement of seat 1
And the scale of the displacement of right clamp 4 is indicated, the wire winding pole 5 is wound in located at the measurement top surface of seat 1, the coiling 6
The wire winding pole 5, the plumb bob 7 are located at the end of the coiling 6.
Preferably, the present apparatus also includes handle 51, and the handle 51 is located at described one end of wire winding pole 5 and drives wire winding pole
5 rotations.The rotation of wire winding pole can be conveniently realized by handle, improves the efficiency of measurement.
