Embodiment 1

[0046] see figure 1 with figure 2 As shown, the purpose of this embodiment is to provide an ultrasonic liquid immersion detection assembly for large bearing rollers, including an outer cabinet 100, a detection device 300 disposed inside the outer cabinet 100, and a control cabinet 200 for controlling the detection device 300, see image 3 As shown, the detection device 300 includes a liquid immersion box 310, which is injected with an ultrasonic coupling medium before detection. During detection, the clamping and rotating drive mechanism 320 provided in the liquid immersion box 310 clamps the roller. Please refer to Figure 4 As shown, specifically:

[0047]The clamping and rotating drive mechanism 320 includes a bottom frame 321, the top sides of the bottom frame 321 are respectively provided with a passive frame 322 and an active frame 323, the passive frame 322 is fixedly connected with the bottom frame 321, the active frame 323 is slidingly connected with the bottom fr...

Embodiment 2

[0051] In order to prevent the external equipment or the hands of the staff from touching the ultrasonic coupling medium in the liquid immersion tank 310 when clamping the rollers, this embodiment is improved on the basis of Embodiment 1, please refer to Figure 7 shown, where:

[0052] Both sides of the clamping and rotating drive mechanism 320 are provided with a lifting assembly 340. The lifting assembly 340 includes a top frame 341. The top frame 341 is fixedly connected with the top of the liquid immersion tank 310. The bottom of the top frame 341 is provided with a mounting block 343. The mounting block 343 is connected to the top of the liquid immersion tank 310. The bottom frame 321 is fixedly connected, and there is an elevating rod 342 between the top frame 341 and the mounting block 343. The elevating rod 342 is driven by a motor to elevate and shrink. When the roller needs to be clamped, the motor drives the elevating rod 342 to shrink , and then drive the top fram...

Embodiment 3

[0055] In order to further improve the clamping strength of the rollers, the embodiment itself improves the sliding connection part of the active frame 323 in Embodiment 1, please refer to Figure 9 shown, where:

[0056] The bottom of the active frame 323 is provided with a base plate 325, and the bottom sides of the base plate 325 are provided with bottom slide rails 3254 along the direction of the moving path of the active frame 323. The base plate 325 and the bottom slide rails 3254 are slidably connected by a bottom slide block 3253 provided. , and is driven by the motor and screw provided at the bottom of the bottom plate 325, and the top of the bottom plate 325 is symmetrically provided with a top slide rail 3251, and the active frame 323 and the top slide rail 3251 are slidably connected by the top slide block 3252 provided, and the top The slider 3252 and the top slide rail 3251 are elastically connected, preferably with a spring, so that when in use, the bottom plate...

Abstract

The invention relates to the technical field of roller detection, in particular to an ultrasonic liquid immersion detection assembly for large bearing rollers. It includes an outer cabinet, a detection device arranged inside the outer cabinet, and a control cabinet for controlling the detection device. The detection device includes a liquid immersion tank, which is injected with an ultrasonic coupling medium before detection, and a clamping device set in the liquid immersion tank The rotating drive mechanism clamps the rollers, and a flaw detection component is installed on the top of the liquid immersion tank to detect the rotating rollers. The invention solves the problem that the roller still rotates due to its own inertia after the active thimble stops rotating, avoids stopping the rotation by hand, improves the safety of use during detection, and at the same time solves the problem of external equipment or work when clamping the roller. The problem of personnel's hands touching the ultrasonic coupling medium in the liquid immersion tank, thereby avoiding the contamination of the ultrasonic coupling medium by external equipment or staff's hands.

Description

technical field [0001] The invention relates to the technical field of roller detection, in particular to an ultrasonic liquid immersion detection assembly for large bearing rollers. Background technique [0002] Ultrasound is a mechanical wave with a frequency higher than 20 kHz. The frequency commonly used in ultrasonic testing is 0.5 to 10 MHz. During flaw detection, the voltage emitted by the pulse oscillator is applied to the probe (detection elements made of piezoelectric ceramics or quartz wafers) ), the ultrasonic pulse sent by the probe enters the material through the ultrasonic coupling medium (such as engine oil or water, etc.) and propagates in it. After encountering a defect, part of the reflected energy returns to the probe along the original path, and the probe converts it into an electrical pulse. Enlarged and displayed on the fluorescent screen of the oscilloscope tube. According to the position and amplitude of the reflected wave of the defect on the fluor...
