Description

Technical Field

[0001] The invention relates to the technical field of steering knuckle detection, in particular to a rapid detection device for a front steering knuckle of an automobile. Background Art

[0002] The steering knuckle is one of the important parts of the steering axle of the car, which can make the car run stably and transmit the driving direction sensitively. The function of the steering knuckle is to transmit and bear the load in front of the car, support and drive the front wheel to rotate around the kingpin to turn the car. The ear of the steering knuckle has two coaxial holes for installing the kingpin, called the kingpin hole. The kingpin hole is connected to the fist-shaped part at both ends of the front axle through the kingpin, so that the front wheel can deflect a certain angle around the kingpin to turn the car.

[0003] Application No. CN201910972530.5 The present invention relates to the technical field of automobile steering knuckles, and in particular to a device for detecting the center height of an automobile steering knuckle, comprising a base, a detection pin, and a dial indicator. The base is provided with a rotating hole, and the detection pin is provided with a spherical detection ball. The center of the detection ball is located on the axis of the detection pin. The dial indicator is connected to the base through a dial rod. During detection, the detection device described above is used to insert the rod of the steering knuckle into the rotating hole, insert the detection pin into the main pin hole of the steering knuckle, and make the probe of the dial indicator contact the surface of the detection ball. The steering knuckle is rotated around the axis of the rod, and the position of the detection ball is adjusted along the axis of the main pin hole so that the reading of the dial indicator remains unchanged. At this time, the intersection of the axis of the main pin hole of the steering knuckle and the axis of the rod coincides with the center of the detection ball. The distance from the large disk surface of the steering knuckle to the vertex of the detection ball is detected, and the radius of the detection ball is added or subtracted to obtain the value of the center height of the steering knuckle. The use is convenient and accurate.

[0004] Based on the search of the above patent and the application of an existing rapid detection device for the front steering knuckle of an automobile, it is understood that currently when detecting the front steering knuckle of an automobile, most of the time only a fixed designated position can be selected for detection. Due to the irregular shape of the front steering knuckle of the automobile, it is difficult to accurately locate the detection position.

[0008] Furthermore, the four corners of the bottom of the equipment rack are respectively fixedly connected with an equipment seat, the bottom of each equipment seat is provided with a height-adjustable support leg, and the bottom of each equipment seat is provided with a universal wheel.

[0009] Furthermore, a limit groove is provided in the middle position of the top of the inspection table, and an insert tube is fixedly connected to the middle position inside the limit groove of the inspection table, the outer position of the insert tube is inserted into the inner position of the steering knuckle part, the lower position of the steering knuckle part is located in the limit groove of the inspection table, and a positioning column is provided at the right front end position of the inspection table.

[0010] Furthermore, a longitudinal scale frame is fixedly connected to the left and right sides of the front end of the assembly frame, and the two longitudinal scale frames are symmetrically designed. The two slide rails of the assembly frame are slidably connected to a sliding seat, and the two sliding seats are symmetrically designed.

[0011] Furthermore, a gear condition is fixedly connected to the inner side of each sliding seat, and the two gear conditions are symmetrically designed, and the two gear conditions are respectively meshed with the left and right sides of the gear member for transmission.

[0012] Furthermore, a distance piece is fixedly connected to the front end of each sliding seat, a strip groove is provided in the middle of each distance piece, and a detector is slidably connected in the strip groove of each distance piece, the sliding position of the detector and the distance piece can be limited, and the distance piece is provided with a scale value.

[0013] Furthermore, a mounting block is fixedly connected to the middle position of the rear end of the adjustment seat, a transverse scale frame is fixedly connected to the top position of the mounting block, and the transverse scale frame is located below the positioning bolt.

[0014] Furthermore, a limit clamp A is fixedly installed at the left rear position of the top of the inspection fixture, and a limit clamp B is fixedly installed at the right rear position of the top of the inspection fixture.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

The structural position of the steering knuckle part will not be offset, so there will be no fixed deviation when testing the automobile steering knuckle.

[0017] 2. When the telescopic part continues to extend, when any detector contacts the steering knuckle part, the position of the steering knuckle part will limit the contacted detector from moving further downward, and the downward movement of the sliding frame will continue to drive the gear part to move. Since the gear part is meshed with the tooth condition that cannot move further, the gear part itself will rotate, so that the other gear part and the currently limited gear part will move in the opposite direction until the two detectors contact the detection part of the steering knuckle part. The sliding length of the sliding seat is read from the position of the two longitudinal scale frames to determine whether the current steering knuckle part is consistent with the standard part scale, so that fast position detection can be performed and data accuracy can be guaranteed.

[0018] 3. The position of the assembly frame and the adjustment seat can slide to adjust the lateral position of the two detectors. When the lateral position of the assembly frame is adjusted, the positions of the two detectors are also adjusted lateraly to adapt to the irregular position selection of the steering knuckle parts themselves. At the same time, the scale value matched by the positioning bolt and the lateral scale frame is read to determine the sliding distance between the assembly frame and the adjustment seat, thereby ensuring the positioning operation of the selected positions of the two detectors.
