Abstract
The utility model relates to a vibration frequency signal acquisition detector for detecting bimetal welding quality, which is arranged in a detection box body cavity made of acoustic insulating materials and provided with a base C for placing detection objects and vibration frequency signal acquisition devices. Each vibration frequency signal acquisition device comprises a base B disposed above the device and a base A disposed on the side of the device. Vibration frequency signal collectors are hung on the bases B and connected with a data processing device outside a detection box body through data lines. The lower ends of the vibration frequency signal collectors are connected with an instigating vibration exciter, an electromagnetic restorer is installed on one side of each base A facing to detection objects, the instigating vibration exciter is contacted with the electromagnetic restorer after swinging to a certain height, and the instigating vibration exciter and the surface of a set height of a workpiece achieve instigating excitation when swinging to the other side. The vibration frequency signal acquisition detector for detecting bimetal welding quality can obtain bimetal diffusion welding quality conclusions of the workpiece by acquiring vibration frequency excitation signals of the workpiece at different positions and processing and analyzing the data.
Description
Technical field
The utility model belongs to thermometal vacuum diffusion welding checkout equipment technical field, relates to a kind of signals collecting detector frequently that shakes that detects the thermometal welding quality.
Background technology
The thermometal vacuum diffusion welding is a kind of solder technology of mutual scattering and permeating between the metallic atom.The quality of welding quality is weighed with weld strength, is directly proportional and the height of weld strength spreads quantity each other with bi-metal atom.The quality that detects thermometal diffusion welding at present also lacks effective means; Because detect the conventional means of metal solder quality at present is supersonic reflectoscope, eddy current testing instrument etc.; These detecting instruments can only detect metallic article inherent vice (like hidden crackle, sand holes, impurity etc.); And can't detect the quantity of phase counterdiffusion between the bi-metal atom, thereby can't detect the quality of thermometal Diffusion Welding.Thermometal diffusion welding mass detector is the detecting instrument that is directed against thermometal diffusion welding welding quality specially.Its basic functional principle is the vibration frequency that detects on the thermometal diffusion welding face of weld.Because material different has different natural frequencys.It is also variant that bi-metal atom spreads its natural frequency of difference of quantity each other, through applying driving frequency, makes on the thermometal face of weld and produce resonance; Detect these resonance frequencies; Through statistics and data analysis, compare test findings again, find out the high and minimum frequency curve of thermometal diffusion welding intensity; With this curve is the vibration frequency that benchmark is differentiated the diffusion welding weldment, just can detect the quality of thermometal diffusion welding welding quality.
Summary of the invention
The purpose of the utility model provides a kind of signals collecting detector frequently that shakes that detects the thermometal welding quality, has solved the detection problem of thermometal diffusion welding welding quality.
The technical scheme that the utility model adopted is; A kind of signals collecting detector frequently that shakes that detects the thermometal welding quality; Be included in the detection box cavity that sound-proof material makes; Be provided with the rotating pedestal C and the signal pickup assembly frequently that shakes that are used to place detected object; Every cover shakes frequently that signal pickup assembly comprises pedestal B that is arranged on the top and the pedestal A that is arranged on the side, and pedestal B is hung with the signal picker frequently that shakes through lug, rotating shaft and back-moving spring, and shaking frequently, signal picker is connected with the external data processing equipment of detection case through data line; The lower end of signal picker that shakes frequently is connected with and instigates vibrator; Towards the one side of detected object the electromagnetism restorer is installed at pedestal A, instigates vibrator and after swinging to certain altitude, touch, instigate vibrator and realize instigating exciting on backswing and the setting height of workpiece surface during to another side with the electromagnetism restorer.
The beneficial effect of the utility model is, compares with existing detection means (like supersonic reflectoscope, magnetic force detector, eddy current testing instrument etc.), and to the detection of thermometal diffusion welding welding quality, detection method is simple, and testing result is accurate.
