DETAILED DESCRIPTION

[0043] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art further understand the present invention, but are not intended to limit the present invention in any way. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention. These modifications and improvements are all within the scope of protection of the present invention.

[0044] See also Figure 1 and Figure 2 The utility model provides an embodiment, a thimble rotary clamp for ultrasonic microscope testing, comprising a thimble part, a caliper part, a driving part and an integration part; the thimble part is used to fix one end of the workpiece to be tested; the caliper part is arranged opposite to the thimble part, and is used to clamp and fix the other end of the workpiece to be tested; the driving part is connected to the caliper part, and drives the caliper part to drive the workpiece to be tested to rotate; the integration part integrates the thimble part, the caliper part and the driving part into one.

[0045] This embodiment uses the ejector part and the caliper part to fix the object to be measured, and uses the driving part to realize the rotation of the object to be measured, thereby realizing complete and non-destructive testing of the component to be measured.

[0046] It should be noted that the object to be tested in this embodiment refers to an object that needs to be tested by an ultrasonic microscope. Its shape is not limited and can be a cylindrical or conical structure, such as a tungsten rod or a stainless steel water pipe.

[0047] In a preferred embodiment of the present invention, a preferred structure of the ejector pin is provided, see Figures 1 to 3 The ejector assembly includes an ejector spring mounting fixture 8, an ejector pin 6, and a spring 7. The ejector spring mounting fixture 8 is fixed to the integrated assembly. The ejector pin 6 is positioned protruding from the sidewall of the ejector spring mounting fixture 8. The spring 7 is positioned around the outer periphery of the ejector pin 6 and compressed between the ejector pin end and the ejector spring mounting fixture 8.

[0048] In a preferred embodiment, Figure 3As shown, ejector spring mounting fixture 8 includes a first bearing seat mounting member 81, a second bearing seat mounting member 82, and a bearing seat assembly 83. First bearing seat mounting member 81 is fixed to the integrated portion; second bearing seat mounting member 82 is vertically fixed to first bearing seat mounting member 81; and bearing seat assembly 83 is mounted on second bearing seat mounting member 82. Second bearing seat mounting member 82 has a through hole. Bearing seat assembly 83 includes a bearing and a bearing seat. The bearing is mounted in the through hole, and the bearing seat is locked to the second bearing seat mounting member via a fixing member. In some specific embodiments, the fixing member may be a screw or bolt.

[0049] Furthermore, ejector pin 6 is cylindrical in shape. One end curves outward and then converges toward the center, forming a cone that presses against a spring mounted around the pin's periphery. The other end of the ejector pin extends into a bearing (in which the ejector pin is movable). When a workpiece is placed between the ejector pin and the caliper, the spring, under pressure, pushes the ejector pin forward and against the workpiece, securing it securely.

[0050] When the length of the workpiece changes slightly, the spring will adjust the compression amount by itself, driving the position of the ejector pin to change, so that the ejector pin part and the caliper part can accommodate workpieces of different lengths.

[0051] Of course, in other embodiments, the installation position of the entire ejector portion on the integrated portion can be adjusted to accommodate workpieces with greater length variations.

[0052] In some specific embodiments, the first bearing seat mounting member 81 is a rectangular plate, and the second bearing seat mounting member 82 is also a rectangular plate. Of course, in other embodiments, their respective shapes are not limited to the only ones, and can be other shapes that can provide a fixed base for the ejector pin 6 and the spring 7.

[0053] In a preferred embodiment of the present invention, a preferred structure of the caliper portion is provided, see Figures 1 to 3 The caliper part includes a three-claw caliper mounting fixture 10, a three-claw caliper 5 and a rotating shaft 12. The three-claw caliper mounting fixture 10 is fixed to the integrated part, and the three-claw caliper 5 is installed on the side of the three-claw caliper mounting fixture 10, opposite to the ejector pin 6, and the center of the three-claw caliper 5 is located in the same straight line as the ejector pin 6. One end of the rotating shaft 12 is fixed to the three-claw caliper 5, and the other end passes through the three-claw caliper mounting fixture 10. The unique structure of the three-claw caliper can be expanded or reduced, and is suitable for objects to be tested in different shapes. In addition, it locks the object to be tested, making it less likely to fall and cause damage. In some specific embodiments, the three-claw caliper can use the three-claw caliper of the K01 series.

[0054] In a preferred embodiment, the structure of the three-claw caliper mounting fixture 10 is similar to that of the ejector spring mounting fixture 8. Figure 4As shown, the assembly includes a base 101, a mounting plate 102, and a bearing assembly 103. The bearing seat assembly 103 includes a bearing and a bearing seat. The base 101 is fixed to the integrated part, and the mounting plate 102 is fixed vertically to the base 101. The mounting plate 102 has a through hole, in which the bearing is installed. The bearing seat secures the bearing to the mounting plate using screws.

[0055] In some specific embodiments, the base 101 and the mounting plate 102 are rectangular block structures. Of course, in other embodiments, other structures can also be adopted, as long as the three-claw caliper 5 and the rotating shaft 12 provide a fixed foundation.

[0056] In a preferred embodiment of the present invention, a preferred structure of the driving part is provided. Figures 1-2 The drive unit includes a motor 1, a motor synchronous pulley 2, a belt 3, and a caliper synchronous pulley 4. The motor 1 provides driving power, the motor synchronous pulley 2 is mounted on the motor output shaft; the caliper synchronous pulley 4 is mounted on the rotating shaft 12; and the belt 3 is sleeved on the motor synchronous pulley 2 and the caliper synchronous pulley 4.

[0057] In a preferred embodiment, a motor mounting bracket 9 is also used, which is fixed upright on the integrated part. The motor 1 is installed on the top of the motor mounting bracket 9 to provide space for the belt to be laid out.

[0058] In a preferred embodiment of the present invention, a preferred structure of the integrated part is provided. Figures 1-2 The integrated portion can be a bottom plate 11, which is set at the bottom layer of all components. It should be noted that the shape and position of the integrated portion are not fixed. In other embodiments, it can be set on the side or other directions of all components to achieve integrated fixation of all components.

[0059] The working principle of the thimble rotary fixture for ultrasonic microscope testing in the above embodiment is as follows:

[0060] like Figure 5 As shown, the motor provides the power for the rotation of the entire device, and transmits the power to the three-grip caliper through a belt and synchronous wheels respectively installed on the rotating shaft of the three-grip caliper and the motor drive shaft, so that the three-grip caliper rotates;

[0061] The three-jaw caliper unfolds and clamps the object under test, rotating it. The other end of the object is secured to the tip of a spring-loaded ejector pin, allowing the pin to rotate with the object. Simultaneously, ultrasonic detection is performed, enabling a full-scale scan of the object.

[0062] When the above test is completed, if the length of the object being measured changes next time, the compression of the spring is adjusted to adjust the length of the ejector protruding from the ejector spring mounting fixture so that the distance between the ejector and the three-jaw caliper is suitable for the new size of the object being measured.

[0063] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
