[0027] The utility model provides a flaw detection device for an automobile steering gear assembly line, and the specific working principle is as follows:

[0028] When the staff uses the device to perform flaw detection on the automobile steering gear, they first need to place the steering gear to be tested on the testing table 21, and perform flaw detection through the testing head 113 to ensure that the quality and performance of the steering gear meet the standard requirements. In this process, if the steering gear needs to be tested from left to right, the staff can start the motor 14 to drive the screw rod 15 to rotate, so that the moving block 17 will move under the drive of the screw rod 15, and the wheel part of the universal wheel 112 will also slide from left to right on the top of the ramp 116. During this sliding process, the testing head 113 will test the steering gear from left to right to ensure that there are no quality problems with the steering gear within the entire range. When the height of the testing head 113 is not enough to detect the steering gear, the staff can start The cylinder 114 generates a strong thrust, which will push the telescopic rod 115 to move forward, so that the bottom of the ramp 116 slides on the slide rail 117. When the ramp 116 moves forward, the wheel part of the universal wheel 112 will pass through the top of the ramp 116 and move upward smoothly. At the same time, the adjustment plate 19 will also move upward, further pushing the slide bar 110 to slide upward in the slot opened in the connecting block 18. In this process, the spring 111 will be deformed by the extrusion force brought by the adjusting plate 19 and the connecting block 18. Through such height adjustment, the detection head 113 can better adapt to steering gears of different heights, so that the detection work can be carried out more conveniently. The detection table 21 can be disassembled and assembled through the fixing part 22, which is convenient for cleaning and maintenance of the detection table 21.
