Description

Automotive Wheel Speed Sensor Testing Device

Technical field:

The utility model relates to a kind of sensor detecting device, specially refers to the pick-up unit of automobile wheel speed sensor.

Background material:

Automobile wheel speed sensor is the crucial sensitive element in the anti-lock braking system in automobiles, and its quality is determining the quality of ABS.Anti-lock braking system in automobiles claims ABS again, and it is the important leverage system of ride safety of automobile, and its use has not only improved the brake efficiency of automobile, the stability of direction when having guaranteed automobile brake, and shortened the braking distance of automobile widely.The wheel speed sensors proving installation is to be used for the special inspecting equipment of testing wheel speed sensors, and it must possess following function: (1) can the velocity of rotation of simulated automotive wheel under the different speed of a motor vehicle; (2) gear ring of dissimilar automobile ABS systems can be installed; (3) sensor of Installation And Test various sizes, type, structure easily; (4) can satisfy the test request that factory produces in batches.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of automobile wheel speed sensor pick-up unit, and it can measure various automobile wheel speed sensors fast.

The utility model adopts following scheme to realize:

Automobile wheel speed sensor pick-up unit described in the utility model, comprise frame, worktable, tray joint shaft, clamping head, gear ring, sensor anchor clamps, automaton and variable-frequency motor, tray joint shaft one end is fixedly connected on the main shaft of variable-frequency motor, and the other end is fixedlyed connected with clamping head; Variable-frequency motor is fixed on the worktable, and the axis of variable-frequency motor is vertical with worktable; Stationary table is provided with the plurality of sensors anchor clamps on worktable on frame, and be evenly distributed in clamping head around; Sensor sleeve to be measured is contained on the sensor anchor clamps, and the detecting head of sensor to be measured and the flank of tooth of gear ring, backlash are corresponding.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Among the figure: the 1-frame; The 2-worktable; The 3-tray joint shaft; The 4-clamping head; The 5-gear ring; 6-sensor anchor clamps; 61-column 62-cross bar; 7-sensor to be measured; The 8-automaton; The 9-variable-frequency motor;

Embodiment:

Automobile wheel speed sensor pick-up unit described in the utility model is by frame 1, worktable 2, tray joint shaft 3, clamping head 4, gear ring 5, sensor anchor clamps 6, sensor to be measured 7, automaton 8, variable-frequency motor 9, tray joint shaft 3 one ends are fixedly mounted on the main shaft of variable-frequency motor 9, the other end is fixedlyed connected with clamping head 4, and described clamping head 4 is a scroll chuck; Worktable 2 is fixed on the frame 1, variable-frequency motor 9 is fixed on the below of worktable 2, eight sensor anchor clamps 6 are housed with centering on gear ring 5 branches such as grade on worktable 2, described sensor anchor clamps 6 by the column 61 that has " T " slide block and the cross bar 62 that is used to install sensor 7 to be measured form, sensor anchor clamps 6 are fixed in the "T"-shaped groove of offering on the worktable 2 by " T " slide block on it, and the detecting head of sensor 7 to be measured is corresponding with the flank of tooth and backlash on the gear ring 5.Drive gear ring 5 rotation with variable-frequency motor 9, rotary state that can simulated automotive wheel under different travelling speed is by the every performance index of its energy measurement wheel speed sensors under the different rotating speeds condition; As clamping head 4, the installation of different size gear ring can be realized with scroll chuck easily, the detection requirement of dissimilar automobile wheel speed sensors can be satisfied; Plurality of sensors anchor clamps 6 are installed on worktable 2 equably, and each sensor anchor clamps 6 can be regulated arbitrarily with respect to the distance between the clamping head 4, the sensor to be measured 7 of test different size, specification, direction can be satisfied, the requirement that once detects a plurality of sensors simultaneously can be satisfied again; Automaton in the utility model can directly obtain the signal of receipts that each sensor collects, and is showing that showing screen shows.
