[0019] The clamp is based on a casing 1, with a plurality of limit members 2 arranged on the outside of the casing 1. The plurality of limit members 2 are distributed in an equidistant array to ensure uniformity and stability of clamping, and are precisely adjusted through a driving assembly 3 installed in the casing 1, and used in conjunction with the limit members 2 to clamp the turbine shaft. The limit members 2 are composed of a slider 201 and an arc plate 207. The inner side of the slider 201 adopts a detachable arc plate 207 design. The user can replace the arc plate 207 of the corresponding size according to the diameter of the turbine shaft to be processed, thereby improving the applicability of the clamp, enabling it to be adapted to turbine shafts of various diameters, and solving the problem of being unable to clamp turbine shafts of different sizes.

[0020] In this embodiment, a slide rail 204 is provided on the inner wall of the slider 201, a slide plate 205 is fixedly connected to the side wall of the arc plate 207 close to the slide rail 204, the slide plate 205 is slidably installed inside the slide rail 204, an anti-slip pattern 208 is provided on the inner side of the arc plate 207, spring rods 206 are symmetrically provided on both side walls of the slide plate 205, the spring rods 206 are composed of a spring and a slide rod, one end of the spring away from the slide rod is fixedly connected to the inner wall of the slide plate 205, the head of the spring rod 206 is tilted, a slideway is provided on the inner wall of the slider 201, a button 203 is provided on the inner wall of the slideway, the spring rod 206 can be plugged into the inner wall of the slideway, and the spring rod 206 abuts against the button 203;

[0021] The slide rail 204 provided on the inner side of the slider 201 provides a stable and smooth sliding path for the spring rod 206, so that the arc plate 207 can be accurately clamped on the slider 201, which not only improves the stability of the arc plate 207, but also makes the disassembly and assembly of the arc plate 207 more convenient, and is convenient for replacement and maintenance. The anti-slip groove 208 enhances the friction between the arc plate 207 and the turbine shaft, improves the stability of the turbine shaft clamping, and prevents the turbine shaft from slipping due to vibration or impact during the processing;

[0022] When the curved plate 207 needs to be replaced, the user presses the button 203 by hand to make the button 203 slide inward of the curved plate 207, so that the spring rod 206 can be pushed out of the slider 201, making it easy to remove the slider 205 from the slide rail 204, thus completing the replacement of the curved plate 207. The operation is simple, which not only improves the efficiency of replacing the curved plate 207, but also reduces the difficulty of operation, making the use of the entire clamp more convenient and efficient.

[0023] In this embodiment, a rotating disk 305 is rotatably installed inside the housing 1, and a threaded ring 306 is fixedly connected to the outer wall of the rotating disk 305.

[0024] When the turntable 305 rotates, the slider 201 is driven to move on the casing 1. The clamping action is achieved by the synchronous movement of multiple sliders 201. In order to facilitate the user's operation, the operator can insert the square rod into the square hole 302 to drive the rotating drum 301. When the rotating drum 301 rotates, it drives the gear 303 to rotate, and then drives the gear ring 304 and the turntable 305 to rotate. The user only needs to simply control the forward or reverse rotation of the square rod to realize the rotation of the threaded ring 306, thereby controlling the opening and tightening actions between the multiple sliders 201. The operation is simple and accurate.
