Specific embodiment
Below according to drawings and examples, the present invention will be further described.
As shown in Figures 1 to 10, a kind of device for ultrasonic method measurement friction welding (FW) weldment excircle dimension, including bottom plate 1,
Support plate, clamping device and pressing plate 5,1 both ends of bottom plate are respectively and fixedly provided with support plate, according to the installation of all parts in Fig. 1
Position, the support plate that mark is mounted on 1 left side of bottom plate is left support plate 3, and the support plate for being mounted on 1 right side of bottom plate is right support plate
13, the upper surface of left support plate 3 is equipped with left support spring 4, and the upper surface of right support plate 13 is equipped with right support spring 12, described
Pressing plate 5 is placed on left support spring 4 and right support spring 12, and left support spring 4 and right support spring 12 jointly play pressing plate 5
To the effect for keeping horizontal position, the clamping device is located between left support plate 3 and right support plate 13, and clamping device includes
Gripping block and fastening spring, the gripping block being mounted in left support plate 3 are left gripping block 7, the clamping being mounted in left support plate 3
Spring is left fastening spring 6, and the gripping block being mounted in right support plate 13 is right gripping block 10, is mounted in right support plate 13
Fastening spring is right fastening spring 11；The gripping block includes circular arc card and the cylinder that is located on circular arc card excircle, is clamped
In the pilot hole of the cylinder installation of block on the supporting plate, the cylinder of the gripping block between the circular arc card and support plate of gripping block
On be set with fastening spring.
As the improvement of the present embodiment, connected between the support plate and bottom plate 1 using bolt 2.Using the activity of bolt
Connection type can select the suitable support plate of size to be mounted on bottom plate 1, that is, guarantee according to the diameter of tested weldment 9
The height of support plate is less than the diameter of tested weldment 9.
