The detection plates are arranged on a guide framework, and the guide framework is driven by the detection plate sliding and positioning device to move. The automobile steering angle detector also comprises a control device used for moving the detection plate sliding and positioning device to a preset location. Since the control device can drive correct positioning of the detection plates according to the preset spacing of front wheels of an automobile, the distance of the detection plates can be automatically fixed.
Description
Technical field
The utility model relates to a kind of steering angle detector, particularly relates to a kind of motor turning angle detector.
Background technology
Vehicle steering left and right sides steering angle can maintenance or impaired after change, thereby but the gyration scope that causes vehicle front not within normal scope of design, if but should can not in time be proofreaied and correct by gyration, can bring very big danger to driving so.
One of project of auto repair will be guaranteed the left and right sides scope unanimity of the steering angle of its front-wheel exactly.Before proofreading and correct steering angle, must measure the angle of accurate front-wheel left and right sides deflection earlier.In the prior art, usually adopt the steering angle detector to come the left and right sides deflection angle of front-wheel is measured, yet, distance between two front-wheels of the automobile of different model is different, when the automobile to different model detects, need adjust the distance between the two detection dishes of steering angle detector.
In addition, after the testing of detection dish finishes, the detection dish differs and gets back to zero-bit and center surely, there is inconsistent phenomenon, because returning zero in it return is to realize that by the strength that is arranged at four extension springs on the detection dish external force of four extension springs has slippage when acting on dial rotation, tension force is inconsistent, the antifatigue degree of each spring also is not quite similar, and makes the angle number of measuring can not guarantee true and reliable.
The utility model content
The purpose of this utility model provides a kind of motor turning angle detector that can adjust detection dish spacing automatically.
For solving the problems of the technologies described above, the utility model is taked following technical scheme: a kind of motor turning angle detector, it is characterized in that: it comprises the detection dish, is used for the clamping device and the detection dish slip locating device of clamping detection dish, described detection dish is arranged on the guide frame, thereby described guide frame is driven and can be subjected to displacement by described detection dish slip locating device, also comprises the control device that is used for described detection dish slip locating device is moved to the precalculated position.
Further, described detection dish also is provided with the gear that cooperates with rotary angle transmitter.
Further, also be provided with at least four springs on described guide frame, described at least four springs are used for described monitor station is returned to reset mode.
Further, described clamping device adopts cylinder or oil cylinder.
Further, described detection dish slip locating device comprise tooth bar, with described tooth bar meshed gears, and the motor that is used to drive described gear.
Further, described control device comprises the measurement mechanism that is used to measure described rack displacement, and described control device is according to the startup of the described motor of FEEDBACK CONTROL of described measurement mechanism and stop.
Further, described control device also comprises input media, and described input media is used for importing spacing between two front-wheels of automobile to be measured in advance to described motor turning angle detector.
Further, described measurement mechanism is a rotary encoder.
Further, described motor turning angle detector also is included in the guide piece that vehicle front leads to front-wheel when sailing into.
Motor turning angle detector in the utility model is owing to have control device, and this control device can drive detection dish correct positioning according to predefined vehicle front spacing, thereby can realize the distance between the detection dish is realized location automatically.

Fig. 2 is the cut-open view of Fig. 1.
Fig. 3 is that A among Fig. 2 is to view.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated.
As Figure 1-3, the motor turning angle detector in the utility model is arranged on the stage body 1.Detection dish 2 by Bearing Installation on the guide frame that is mounted slidably along described stage body 1, on described detection dish 2, also be provided with the gear that cooperates with rotary angle transmitter, therefore, when rotating under the drive of described detection dish 2 at vehicle front, gear driven rotary angle transmitter on the described detection dish 2 and rotating, thus the rotational angle of described rotary angle transmitter with described front-wheel detected.
On described guide frame, also be arranged at intervals with to equal angles four springs 4, described four springs 4 are used for described detection dish 2 is returned to initial reset mode, simultaneously, both sides at described detection dish 2 also are provided with two clamping devices 5 respectively symmetrically, and preferably, described clamping device 5 adopts cylinder or oil cylinder, when the piston rod on described two clamping devices 5 be driven stretch out after, described two piston rods coil 2 clampings location with described detection, thereby are fixed, and are subjected to displacement to avoid it.When described two piston rods shrank, described detection dish 2 was in free state, at this moment, thereby described detection dish 2 can freely rotate the vehicle front corner is measured.
Described guide frame is fixed on the slide rail of table top 1, and described guide frame is provided with and is used to drive the sliding rack 6 that described guide frame slides along described slide rail, described sliding rack 6 is meshed with a slide gear 7, and described slide gear 7 is driven by a motor (not shown); Described motor can drive described slide gear 7 rotations, slides along described slide rail to drive described guide frame thereby further drive described tooth bar 6.Especially, also be provided with the control device (not shown) of the described guide frame of control on the detector of described motor turning angle.Described control device comprises the measurement mechanism that is used to measure described tooth bar 7 displacements, vehicle front spacing input media, described vehicle front spacing input media is used for the vehicle front spacing of specific model is set in advance described control device, when detecting corner, described control device is opened described motor, thereby drive described slide gear 7, sliding rack 6 drives described guide frame and slides, simultaneously, described measurement mechanism is monitored the displacement of described guide frame, and the result of described monitoring fed back to described control device, when described control device determines that by moving of guide frame two spacings between the described detection dish that is respectively applied for two vehicle fronts reach described predefined vehicle front spacing, described control device stops described motor, thereby 2 correct positioning are coiled in described two detections.Preferably, the measurement mechanism of described tooth bar 6 displacements is rotary encoders 8.
Import the front-wheel spacing of automobile to be measured before detecting earlier, predetermined described front-wheel spacing place adjusted to the spacing between two detection dishes 2 automatically by described then control device; Then, vehicle front is reached detection dish 2, and discharge the clamping of 5 pairs of detection dishes 2 of described clamping device, thereby make detection dish 2 be in free state, at this moment, vehicle steering spins, make its front-wheel maximal value of turning right respectively left, by the rotary angle transmitter under the measuring disk 2, transfer the rotational angle of described front-wheel to electric signal and be transferred in the calculating display part in the described control device and handle, thereby the angle value that front-wheel rotates is measured and shown.
