The special-purpose ABS gear detection device is characterized in that the support seat is rotatably equipped with a rotation shaft, an output end of the rotation shaft is equipped with a transmission gear, the other end of the rotation shaft is equipped with a synchronous belt wheel, the synchronous belt wheel is driven by a motor at one side of the synchronous belt wheel, the support seat at one side of the rotation shaft is provided with a fixing shaft which is parallel with the support seat, the fixing shaft is rotatably equipped with a shaft sleeve, an upper end portion of the shaft sleeve is provided with a projection matching with a gear key slot to be detected, and the shaft sleeve below the projection is provided with an annular boss. The special-purpose ABS gear detection device has reasonable structure design, through a mode of the motor driving the synchronous belt wheel to connect a bearing, balance precision of the shaft is improved, errors are reduced, detection precision is greatly improved, moreover, an ABS gear to be detected is easy to position, and positioning is precise.

Description

A kind of special-purpose ABS gear pick-up unit for preparing abs sensor detection frock

Technical field

The utility model relates to a kind of gear pick-up unit, relates in particular to a kind of special-purpose ABS gear pick-up unit that abs sensor detects frock for preparing.

Background technology

Dynamo-electric hydraulic pressure and Electromechanical Design that electronic control technology has used Controlled by Microcomputer in a large number have been extensive use of on the Hyundai Motor, the system that comes to this of ABS system, the ABS system uses four wheel speed sensors to be input signal, for guaranteeing the operate as normal of ABS system, must before dispatching from the factory, test to all wheel speed sensors signals, usually the method for sort signal detection mostly adopts ABS sensor equipment that it is detected, its complex structure, the manufacturing cost height, detecting the output data demonstration shows by scale value, detection for sensor, its video data jitter values is less, be not easy to observe and detect, can not satisfy use, mostly adopt special-purpose detection frock to be equipped with expensive digital collection and molecular system in the prior art for addressing this problem, the quality of fit with ABS sensor to be detected that detects frock in this equipment has had a strong impact on testing result, so before frock making, need the ABS gear is detected, make suitable frock with correlation parameter according to the ABS gear, but existing detection mainly is to rotate with the direct driven gear of motor, the error ratio that detects is bigger, and the position of ABS gear is not easy to determine or the position is inaccurate, influences measurement result.

The utility model content

The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of special-purpose ABS gear pick-up unit that abs sensor detects frock for preparing is provided, by driven by motor synchronously with the mode of connection bearing, the shaft balancing precision is improved, reduced error, the precision of detection is improved greatly, the easy location of ABS gear to be detected, and accurate positioning simultaneously.

The utility model is achieved through the following technical solutions:

A kind of special-purpose ABS gear pick-up unit for preparing abs sensor detection frock, include supporting seat, it is characterized in that: be rotatablely equipped with rotating shaft on the described supporting seat, the output terminal of described rotating shaft is equipped with transmission gear, the other end of described rotating shaft is equipped with synchronous pulley, described synchronous pulley is by the motor-driven of one side, the supporting seat of described rotating shaft one side is provided with stationary shaft in parallel, be rotatablely equipped with axle sleeve on the described stationary shaft, the upper end of described axle sleeve is provided with a projection that cooperates with gear keyway to be detected, and the axle sleeve of described projection below is provided with annular boss.

The signal wire of described motor is connected with the single-chip data processor, calculate variation in real time with the output frequency that shows motor, cooperate known standard transmission gear and with the centre distance and the monodentate distance of ABS gear to be detected, and then detect gear ring, the number of teeth, the modulus of ABS gear to be detected, and then detect frock according to the laid down by abs sensor.

Distance between described rotating shaft and the stationary shaft can guarantee that the backlash between transmission gear and the ABS gear to be detected is 0.6-0.8mm.

Its principle is: utilize driven by motor synchronous pulley motion, by the bearing assembling, reduce to rub and the fixing mode in axle center makes the gear plane vertical with the axle maintenance; Its kind of drive improves the shaft balancing precision, reduced error, the precision of detection is improved greatly, cooperate stationary shaft, the structure of axle sleeve and the structural design of projection and annular boss of placing fixing ABS gear to be detected simultaneously, make the easy location of ABS gear to be detected, and accurate positioning.Determine the position of stationary shaft in the process earlier, distance between itself and the rotating shaft can guarantee that the backlash between transmission gear and the ABS gear to be detected is 0.6-0.8mm, then ABS gear to be detected is placed on the axle sleeve and is mated, by of the processing of single-chip data processor to motor frequency signal, calculate variation in real time with the output frequency that shows motor, cooperate known standard transmission gear and with the centre distance and the monodentate distance of ABS gear to be detected, and then detect the gear ring of ABS gear to be detected, the number of teeth, modulus, and then according to laid down by abs sensor detection frock.

The utility model has the advantages that:

The utility model reasonable in design synchronously with the mode of connection bearing, improves the shaft balancing precision by driven by motor, has reduced error, and the precision of detection is improved greatly, the easy location of ABS gear to be detected, and accurate positioning simultaneously.
