Description

Technical Field

[0001] This utility model belongs to the technical field of automotive parts testing devices, specifically relating to the structure of a welding penetration depth testing device for automotive clutch hub parts. Background Technology

[0002] In AT (automatic transmission) and CVT (continuously variable transmission), power is transmitted to the clutch hub input shaft via splines, and then to the friction plates via the splines of the clutch hub. The friction plates then transmit the power to the transmission gear system, thereby achieving speed and torque changes.

[0003] The input shaft and the spline of the clutch hub assembly are mainly connected by welding. To ensure the reliability and durability of the power transmission process, the welding strength of the parts is a very important product indicator, and the weld penetration is one of the key factors to ensure the welding strength.

[0004] Existing technologies for weld penetration testing typically employ destructive testing methods, which can only test cut-out samples and cannot test the entire weld. This also increases testing time and reduces production efficiency.

[0005] Ultrasonic nondestructive testing technology is an effective means of detecting internal defects in materials. It is convenient and efficient, and is mainly used for detecting internal defects in thin-walled parts or surface defects in large parts, with high detection accuracy. Utility Model Content

[0049] The part positioning module mainly consists of a transfer plate. One end of the transfer plate is assembled with the hub assembly input shaft, and the center positioning and end face positioning are respectively achieved through the center hole and end face of the input shaft. The other end of the transfer plate is assembled with a rotary positioning plate to realize that the motor drives the part to rotate at a constant speed.

[0050] The part positioning module is mainly used to achieve precise positioning of the part and to ensure that the weld seam passes through the detection area evenly during the detection process.

[0051] Furthermore, the detection and positioning module mainly consists of an upper and lower linear module, a left and right linear module, and a precision rotating platform.

The ultrasonic control includes the gain, delay, and length of the ultrasonic signal. The gate control includes the length, width, and threshold settings of the interface gate and the defect gate. The interface gate is mainly used to set the parameters of the reflected wave (interface wave) at the interface of different media, and the defect gate is mainly used to set the parameters of the reflected wave (defect wave) at the internal defects of the part.

[0058] By processing the reflected waveform of the defective sample, the judgment parameters of the part to be inspected can be determined, and then the penetration depth of the normal welded parts can be inspected.
