[0002] Shaft components are common and important parts in mechanical systems, and are among the most frequently encountered typical parts in mechanical component accessories. They are mainly used to support transmission components, transmit torque, and bear loads. They are generally in the shape of a metal rod, and each section can have different diameters. Depending on the application environment, shaft components come in various types and specifications, such as different lengths, diameters, transmission ratios, and torque capacities, to meet the specific requirements of various transmission systems. As precision transmission components and drive shafts, shaft components are usually manufactured using high-precision machining processes and high-quality materials, possessing high dimensional accuracy, surface finish, and mechanical properties.

[0018] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0019] Example: Refer to Figure 1 - Figure 2 As shown, a clamping device for detecting shaft components in this embodiment includes a mounting base 1. A semi-circular mold groove 2 is provided on the upper surface of the mounting base 1. Limiting clamps 3 are provided on both sides of the upper end of the mold groove 2. A rocker arm 4 is provided on the back of the limiting clamp 3. The rocker arm 4 is movably mounted on both sides of the upper end of the mounting base 1. A drive rod 5 is movably connected to the bottom end of the rocker arm 4. A sliding block 6 is movably connected to the bottom of the drive rod 5. The sliding block 6 is movably mounted in the middle of the inner side of the mounting base 1, and a drive cylinder 9 is connected to the bottom of the sliding block 6.

[0020] The sliding block 6 can be pushed by starting the drive cylinder 9, causing it to rise. When the sliding block 6 rises, it drives the drive rods 5 on both sides, which in turn push the bottom of the rocker arm 4, causing it to rotate. This causes the two limit clamping plates 3 on both sides to rotate towards the center, forming a clamping shape between the two limit clamping plates 3 and the mold groove 2, thereby clamping and fixing the shaft components placed on the surface of the mold groove 2.

[0021] The mounting base 1 has a rotating body 11 and a fixed base 10 at its bottom. The rotating body 11 is movably mounted in the middle of the inner side of the fixed base 10, and the mounting base 1 is fixedly mounted on the upper surface of the rotating body 11. A rotating gear 13 is fixedly mounted on the outer wall of the rotating body 11. The rotating gear 13 is located in the middle of the inner side of the fixed base 10, and a drive gear 14 is meshed with the left end of the rotating gear 13. The drive gear 14 is movably mounted in the left inner side of the fixed base 10, and a drive motor 15 is connected to the bottom of the drive gear 14. The drive motor 15 is fixedly mounted on the bottom left side of the fixed base 10.

[0022] The drive motor 15 drives the drive gear 14 to rotate, and the transmission causes the rotating gear 13 to drive the rotating body 11 to rotate, thereby driving the mounting base 1 to rotate 360 ​​degrees, thus providing convenience for the inspection of the shaft components.

[0023] In some examples, the inner ends of the mounting base 1 are provided with limit guide rods 7, and both sets of limit guide rods 7 are slidably connected to the sliding block 6; a support plate 8 is provided at the bottom of the mounting base 1, and a drive cylinder 9 is fixedly installed in the middle of the bottom end of the support plate 8. The output end of the drive cylinder 9 passes through the support plate 8 and is fixedly connected to the bottom of the sliding block 6. The support plate 8 mainly provides stable support for the drive cylinder 9 and the two sets of limit guide rods 7.

[0024] In some examples, bearings 12 are provided at both ends of the outer wall of the rotating body 11. The bearings 12 enable the rotating body 11 to be movably connected to the fixed base 10. The bearings 12 enhance the stability and smoothness of the rotating body 11 during rotation.

[0025] In some examples, when the mold groove 2 is surrounded by two sets of limiting clamps 3, its inner hole forms a circular structure, thereby clamping and fixing the shaft components placed on the surface of the mold groove 2 and enhancing stability.

[0026] In some examples, the rotating body 11 is configured as a hollow structure, and during use, the driving cylinder 9 is located in the inner cavity of the rotating body 11.

[0027] The working principle of this utility model is as follows:

[0028] This utility model uses the mold groove 2 and two sets of limiting clamps 3 to enclose the shaft component, which can quickly clamp and position the shaft component. At the same time, during the inspection process, the rotating body 11 is driven to rotate, which allows the shaft component to be rotated and positioned 360 degrees, thus providing convenience for the inspection of the shaft component.

[0029] The specific operating procedure is as follows: First, the operator places the shaft component on the upper surface of the mold groove 2. Then, the drive cylinder 9 is started. The drive cylinder 9 pushes the sliding block 6 to move up and down. When the sliding block 6 moves up, it pushes the drive rods 5 on both sides, which in turn pushes the rocker arm 4. Under the rotation of the rocker arm 4, the limiting clamps 3 on both sides rotate synchronously towards the center, so that the two sets of limiting clamps 3 and the mold groove 2 form an enclosing shape, thereby clamping and fixing the shaft component placed on the surface of the mold groove 2 and enhancing the stability of the shaft component in the inspection work.

[0030] In addition, when it is necessary to rotate and adjust the position of the shaft component, the drive motor 15 is started first. The drive motor 15 drives the drive gear 14 to rotate. Under the action of the transmission force, the drive gear 13 drives the rotating body 11 to rotate, which in turn drives the mounting base 1 to rotate. With the rotation of the rotating body 11, the operator can rotate and adjust the shaft component 360 degrees, thus providing convenience for the inspection of the shaft component.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
