Device for testing sound quality of parts and fixing method thereof

The invention relates to the technical field of sound quality tests of related electronic parts in automobile NVH tests, in particular to a device for testing the sound quality of parts and a fixing method of the device. A boss is fixed above the right side of the base, one end of the worm is connected into the boss, and the other end of the worm is connected to the right side of the base and connected with the rocker. The sliding block is arranged outside the worm in a sleeving mode and connected with the worm through threads in a meshed mode. When a mechanism is clamped, an operator only needs to rotate the nut to fix the mechanism, meanwhile, the clamping force can be well controlled by rotating the nut, the mechanism is prevented from being damaged, the device is simple in structure and convenient to achieve, angle control is conducted through locking of the worm, the structure is stable, and the bearing performance is good. 本发明涉及汽车NVH试验中相关电子零部件声品质试验技术领域，具体涉及一种零部件声品质测试用装置及其固定方法；其中底座右侧上方固定有凸台，蜗杆一端连接在凸台内，另一
