[0038] 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.

[0039] Figure 1This is a schematic diagram of the structure of a rotary roller fixture for ultrasonic microscopy testing, according to one embodiment of the present invention. The fixture comprises a roller 1, a fixing portion, a drive portion, and an integration portion. Two rollers 1 are placed side by side and co-located, supporting and rotating the test piece. The fixing portions are located at each end of the rollers, providing support. The drive portion connects the rollers and drives their rotation. The integration portion integrates the rollers, fixing portion, and drive portion into a single unit.

[0040] This embodiment uses two side-by-side rollers to achieve the fixation and rotation of the measured object, solving the problem in the prior art that a circular measured object is difficult to clamp and rotate.

[0041] In a preferred embodiment of the present invention, a preferred structure of a roller is provided. The diameter and length of the two rollers are equal, and the test piece is placed between the two rollers. The roller consists of a rotating shaft and a roller body. Both ends of the rotating shaft are inserted into the fixed part, and the rotation in the fixed part is achieved by bearings. The roller body remains coaxial with the rotating shaft. It can be a cylinder with a hollow center, which is directly mounted on the rotating shaft and fixed by a jackscrew or screw; or it can be spliced ​​together by two semi-cylinders, which are also fixed to the rotating shaft by a jackscrew or screw. By removing and installing the jackscrew or screw, the roller body can move left and right on the rotating shaft.

[0042] Furthermore, each rotating shaft is equipped with one or more rollers; when the number of rollers is one, the single roller is arranged at the center of the rotating shaft, such as Figure 1 When there are two rollers, the two rollers are arranged at opposite ends of the rotating shaft, as shown in FIG. Figure 2 As shown; when the number of rollers is greater than two, multiple rollers are evenly distributed on the rotating shaft.

[0043] Of course, in some other embodiments, in order to achieve synchronous rotation of workpieces of different sizes and materials, a strategy of adjusting the roller material can be adopted to change its surface friction coefficient. This adjustment process is based on the calculation formula of static friction: F = μsN. Among them, F represents the magnitude of the static friction force, and μs is the static friction coefficient. As a dimensionless constant, it is affected by the material and surface state of the two objects, and its value range is usually between 0 and 1. N represents the normal pressure perpendicular to the contact surface, that is, the force between objects perpendicular to the contact surface due to gravity or external force. In order to ensure that workpieces of different materials, weights, lengths and diameters can be driven synchronously, it is necessary to ensure that the static friction between them is equal. Therefore, based on the known normal pressure and the above calculation formula, the static friction coefficient can be accurately calculated, so as to select the material of the required roller to achieve the purpose of synchronous rotation.

[0044] In a preferred embodiment of the present invention, a preferred structure for the fixing portion is provided. The fixing portion is a rectangular support, into which the ends of the rollers are inserted with bearings. The rollers are suspended from the integrated portion, ensuring that the rollers are not obstructed during rotation. Two rectangular supports are provided, with the ends of different rollers facing in the same direction inserted into the same rectangular support. Of course, in other embodiments, the shape of the fixing portion is not a limitation; any shape that can provide rotational support for both ends of the rollers is acceptable.

[0045] In a preferred embodiment of the present invention, a preferred structure of a drive unit is provided. The drive unit includes a motor 1, a motor synchronous pulley 2, a belt 3, a roller synchronous pulley 5, and a timing belt 6. The motor 1 outputs rotational power; the motor synchronous pulley 2 is mounted on the motor output shaft; there are three roller synchronous pulleys 5, with roller synchronous pulleys 5 mounted on both ends of one roller 4, and only on one end of the other roller 4; a timing belt 6 connects the two roller synchronous pulleys 5 located at the same end of the two rollers; and the belt 3 connects the motor synchronous pulley 2 and the roller synchronous pulley 5 located opposite the timing belt.

[0046] Furthermore, the drive unit includes a motor mounting bracket 8, secured to the integrated unit and used to mount the motor. In this embodiment, the motor mounting bracket 8 is a vertically arranged plate-like structure with the motor mounted on its top, maintaining the motor's synchronous pulley and the roller's synchronous pulley in the same plane. Of course, in other embodiments, the structure of the motor mounting bracket is not limited and can be any structure that can secure and support the motor.

[0047] In a preferred embodiment of the present invention, a preferred structure for an integrated unit is provided. The integrated unit is a rectangular base plate 7, located at the base of the roller, fixed unit, and drive unit. The fixed unit utilizes a rectangular support, secured to the base plate 7 with screws. The motor mounting bracket 8 in the drive unit is also secured to the base plate 7 with screws. Of course, in other embodiments, the shape and placement of the integrated unit are not limited and can be positioned on the side of all components or in other directions to achieve integrated and fixed assembly of all components.

[0048] The working principle of the rotary drum fixture for ultrasonic microscope testing in the above embodiment is as follows:

[0049] Place the test piece on top of the two rollers with its axis aligned with the rollers, e.g. Figure 3 shown.

[0050] The motor 1 provides the power for the whole device to rotate. The power is transmitted to the roller 4 through the belt 2 and the motor synchronous wheel 2 installed on the roller 4 and the motor drive shaft respectively, so that the roller 4 rotates.

[0051] At the same time, the roller 4 transmits power to another identical roller 4 placed side by side through the roller synchronous wheel 5 and the synchronous belt 6 at the other end, so that it rotates in the same direction and at the same speed, thereby driving the test piece to rotate and perform ultrasonic testing at the same time, realizing a full-range scan of the test piece;

[0052] The rotating fixture for the measured object in the above embodiment of the utility model patent realizes the rotation of the measured object above by the synchronous rotation of two adjacent rollers. Compared with other fixtures in the prior art, the embodiment of the utility model will not cause damage to the measured object, and is suitable for cylindrical parts of various lengths and sizes, is easy to pick up, and has a simple structure.

[0053] 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.
