Example

[0025] Depend on Figures 1-6This invention discloses a flaw detection device for automotive steering gear housings, comprising a support assembly 1, which supports a circumferential drive assembly 2 and carries an ultrasonic testing medium. The circumferential drive assembly 2 drives a linear lifting assembly 3 to rotate circumferentially, and the linear lifting assembly 3 drives a carrier assembly 4 to linearly lift and lower into and out of the ultrasonic testing medium. The carrier assembly 4 carries the automotive steering gear housing, and the linear drive assembly 5 drives an ultrasonic detector 6 to move linearly, ensuring that the detection surface of the ultrasonic detector 6 covers the entire automotive steering gear housing. The ultrasonic detector 6 emits ultrasonic waves that pass through the ultrasonic testing medium carried inside the support assembly 1 to perform flaw detection on the automotive steering gear housing. This invention achieves rapid flaw detection of automotive steering gear housings, and the flaw detection process is fully automated, which not only improves the detection efficiency of automotive steering gear housings but also ensures the product quality of finished automotive steering gear housings.

[0026] Specifically, the support assembly 1 includes a base 101. The upper surface of the base 101 is provided with a plurality of detection slots 102 and material exchange slots 103, and the plurality of detection slots 102 and material exchange slots 103 are evenly and alternately distributed. A water inlet pipe 104 and a drain pipe 105 are inserted into the inner side wall of the detection slot 102, wherein the water inlet pipe 104 is located above the drain pipe 105. The plurality of detection slots 102 and material exchange slots 103 alternately arranged so that the automotive steering gear housing inside the detection slot 102 can be loaded and unloaded during the flaw detection process.

[0027] Specifically, the circumferential drive assembly 2 includes a first servo motor 201, which is disposed on the upper surface of the base 101. The output shaft of the first servo motor 201 is connected to one end of a rotating shaft 202, and the other end of the rotating shaft 202 is detachably connected to a support column 203. A support plate 204 is disposed on the upper end of the support column 203. A limit hole 205 is provided on the upper surface of the support plate 204. The first servo motor 201 drives the rotating shaft 202 to rotate, thereby driving the support plate 204 to rotate circumferentially, which in turn drives the steering gear housing of the car to be tested to rotate to the position above the detection slot 102.

[0028] Specifically, the linear lifting assembly 3 includes an electric hydraulic cylinder 301, which is detachably connected to the outer wall of the bottom surface of the support plate 204. One end of a hydraulic telescopic rod 302 is slidably connected to the inner wall of the electric hydraulic cylinder 301, and the other end of the hydraulic telescopic rod 302 is detachably connected to a support ring 303. A limit rod 304 is provided on the upper surface of the support ring 303. The outer wall of the limit rod 304 is slidably connected to the inner wall of the limit hole 205. The operation of the electric hydraulic cylinder 301 drives the hydraulic telescopic rod 302 to extend and slide, thereby driving the support ring 303 to move linearly upward. This, in turn, drives the steering gear housing and the support plate 402 of the vehicle under test to move linearly, making the outer wall of the bottom surface of the support plate 402 higher than the upper surface of the base 101.

[0029] Specifically, the bearing assembly 4 includes a vertical plate 401, which is disposed on the outer wall of the bottom surface of the support ring 303. A bearing plate 402 is disposed on the outer wall of the bottom surface of the vertical plate 401, and a bearing groove 403 is formed on the upper surface of the bearing plate 402. A through hole 404 is formed on the inner wall of the bottom surface of the bearing groove 403. The through hole 404 on the inner wall of the bottom surface of the bearing groove 403 enables the test vehicle steering gear housing inside the bearing groove 403 to move stably and linearly.

[0030] Specifically, the linear drive assembly 5 includes a connecting plate 501, which is detachably connected to the outer wall of the bottom surface of the support ring 303. The outer wall of the connecting plate 501 has a side hole 502, and the inner wall of the bottom surface of the side hole 502 has a vertical hole 503. A second servo motor 504 is detachably connected to the inner wall of the side hole 502. The output shaft of the second servo motor 504 is connected to one end of a lead screw 505, and the other end of the lead screw 505 is rotatably connected to the inner wall of the side hole 502. A ball nut 506 is provided on the outer wall of the lead screw 505, and a slider 507 is detachably connected to the outer wall of the ball nut 506. An ultrasonic detector 6 is provided on the outer wall of the bottom surface of the 07; a sliding hole 508 is provided on the outer wall of the slider 507, and a crossbar 509 is provided on the inner wall of the side hole 502. The outer wall of the crossbar 509 is slidably connected to the inner wall of the sliding hole 508. The second servo motor 504 drives the lead screw 505 to rotate, thereby driving the slider 507 to move linearly under the cooperation of the ball nut 506 and the sliding of the sliding hole 508 and the outer wall of the crossbar 509. This allows the ultrasonic detector 6 to cover the car steering gear housing inside the bearing groove 403. In this way, the ultrasonic detector 6 can complete the flaw detection operation of the car steering gear housing to be tested by running and emitting ultrasonic waves.

[0031] Specifically, there are multiple load-bearing components 4 and linear drive components 5, and the multiple load-bearing components 4 and linear drive components 5 are evenly distributed on the outer wall of the bottom surface of the support ring 303. The multiple load-bearing components 4, linear drive components 5 and ultrasonic detectors 6 enable a single device to perform flaw detection operations on multiple automotive steering gear housings simultaneously.

[0032] Specifically, there are multiple limiting rods 304, and the multiple limiting rods 304 are evenly distributed on the upper surface of the support ring 303. The stability of the linear lifting and lowering movement of the support ring 303 and the steering gear housing of the vehicle under test is ensured by the cooperation of the limiting rods 304 sliding along the limiting hole 205.

[0033] In use, the ultrasonic testing medium is first introduced into the testing tank 102 through the water inlet pipe 104. Then, the car steering gear housing to be tested is moved and placed on the inner wall of the bottom surface of the bearing tank 403 in the material changing tank 103. Next, the electric hydraulic cylinder 301 drives the hydraulic telescopic rod 302 to extend and slide, thereby driving the support ring 303 to move linearly upward. This, in turn, drives the car steering gear housing to be tested and the bearing plate 402 to move linearly, making the outer wall of the bottom surface of the bearing plate 402 higher than the upper surface of the base 101. At the same time, the limiting rod 304 slides along the limiting hole 205. The action ensures the stability of the linear lifting and lowering movement of the support ring 303 and the steering gear housing to be tested. Then, the first servo motor 201 drives the rotating shaft 202 to rotate, thereby driving the support plate 204 to rotate circumferentially. This, in turn, drives the steering gear housing to be tested to rotate to the position above the detection groove 102. Subsequently, the electric hydraulic cylinder 301 drives the hydraulic telescopic rod 302 to extend and slide, thereby driving the support ring 303 to move linearly downward. This, in turn, drives the steering gear housing to be tested and the bearing plate 402 to move linearly, thus enabling the steering gear housing and the ultrasonic detection... The detection surface of the ultrasonic detector 6 falls into the ultrasonic detection medium inside the detection groove 102. Then, the second servo motor 504 drives the lead screw 505 to rotate, which, under the cooperation of the ball nut 506 and the sliding hole 508 sliding on the outer wall of the crossbar 509, drives the slider 507 to move linearly. This causes the ultrasonic detector 6 to cover the car steering gear housing inside the bearing groove 403. In this way, the ultrasonic detector 6 operates and emits ultrasonic waves to complete the flaw detection operation of the car steering gear housing to be tested, effectively realizing the device's ability to quickly detect flaws in the car steering gear housing. The device has a detection function and the flaw detection process is fully automated, which not only improves the detection efficiency of automotive steering gear housings, but also ensures the product quality of finished automotive steering gear housings. The alternating arrangement of multiple detection slots 102 and material exchange slots 103 allows the automotive steering gear housings inside the detection slots 102 to be loaded and unloaded during the flaw detection process. At the same time, the multiple load-bearing components 4, linear drive components 5 and ultrasonic detectors 6 enable a single device to perform flaw detection operations on multiple automotive steering gear housings simultaneously.
