DETAILED DESCRIPTION

[0021] See also Figure 2 A driven gear 5 is fixedly sleeved on the rotating shaft 4, and the driven gear 5 is meshed and connected with a driving gear 6 on one side. The driving gear 6 is fixedly sleeved on one end of the output shaft of the first motor 7. The first motor 7 is fixedly installed on the upper surface of the base 1 and is located below the turntable 301. After the first motor 7 is started to drive the driving gear 6 to rotate, the rotating shaft 4 can be driven to rotate through the meshing connection between the driving gear 6 and the driven gear 5, thereby driving the turntable assembly 3 to rotate as a whole. The angle of the steel pipe can be adjusted during the production and processing of seamless steel pipes, providing convenience for use.

[0022] Furthermore, one end of each bidirectional screw rod 303 extends to the outside of the turntable 301 through a through hole provided on the inner wall of one end of the corresponding adjusting groove 302 and is provided with a knob 304. By providing the knob 304, the bidirectional screw rod 303 can be more conveniently rotated, thereby adjusting the distance between the two sliders 305 in the same adjusting groove 302, and thus adjusting the distance between a corresponding set of fastening and clamping components 2, which can be adjusted according to the length of the steel pipe to reduce limitations in use.

[0023] See also Figure 3 and Figure 4Each fastening and clamping assembly 2 includes a fixed disk 201 and a rotating disk 202. The fixed disk 201 and the rotating disk 202 are coaxially arranged and both are provided with matching placement holes. The fixed disk 201 and the rotating disk 202 are fitted on one side surface and the fixed disk 201 is located on the side surface and is provided with a plurality of linear slide grooves 203 evenly distributed in an annular shape. A slide rod 204 is slidably installed in each linear slide groove 203. A clamping portion 205 is provided at one end of each slide rod 204. A clamping portion 205 is provided at one end of each slide rod 204. The surface of each linkage rod 206 is fixedly connected with one end thereof, and each linkage rod 206 is slidably installed in a corresponding arc groove 207. A plurality of arc grooves 207 are evenly distributed on the surface of one side of the rotating disk 202 in an annular shape and penetrate the rotating disk 202. One end of each linkage rod 206 extends to the other side of the linkage rod 206 through the arc groove 207 and is provided with a limiting block 208. A gear ring 209 is provided on the outer wall of the circumference of the rotating disk 202. The rotating disk 202 is connected to a driving gear 208 on one side through the gear ring 209. 10 meshing connection, the driving gear 210 is fixedly sleeved on one end of the output shaft of the second motor 211, the second motor 211 is fixedly mounted on the upper surface of the mounting plate 212, and the mounting plate 212 is fixedly connected to the corresponding slider 305. When each second motor 211 is started, the corresponding rotating disk 202 is driven to rotate through the meshing relationship between the driving gear 210 and the gear ring 209. When the rotating disk 202 rotates on one side of the fixed disk 201, the position of the arc slot 207 will be displaced, thereby forcing the coupling The movable rod 206 is displaced in the arc groove 207. When the linkage rod 206 is displaced, it will drive the slide rod 204 to slide in the linear groove 203. Therefore, all the clamping parts 205 in each fastening and clamping assembly 2 will be synchronously displaced toward the axial direction of the placement hole to clamp the seamless steel pipe. Because the second motor 211 will self-lock after power is cut off, when the steel pipe is clamped by the fastening and clamping assembly 2, the steel pipe can be more firmly limited during production and processing to ensure stability during use.

[0024] Furthermore, a rubber anti-skid pad is provided on the surface of one side of each clamping portion 205 facing the axis of the fixed disk 201. By providing the rubber anti-skid pad, the clamping stability can be improved to prevent the steel pipe from rotating between the clamping portions 205, and the clamping portion 205 can be prevented from scratching the outer wall of the steel pipe, thereby reducing the loss rate during production and processing.

[0025] Furthermore, the number of the linear slide grooves 203 is at least three, and the steel pipe can be axially clamped and limited by at least three groups of clamping parts 205 to prevent the steel pipe from being displaced due to external forces during production and processing, thereby reducing the efficiency of production and processing.

[0026] Working principle: The two fastening and clamping components 2 in the same group are adjusted according to the length of the seamless steel pipe produced and the processing requirements, and the bidirectional screw rod 303 is rotated by the knob 304. Because the two sections of the thread direction of the bidirectional screw rod 303 are opposite and the two sliders 305 are threadedly connected to the two ends of the bidirectional screw rod 303, the bidirectional screw rod 303 will drive the sliders 305 on both sides to move in opposite directions when it rotates, thereby adjusting the distance between the two fastening and clamping components 2 and reducing the limitations in use. The second motor 211 in each fastening and clamping component 2 is started to drive each rotating disk 202 to rotate, thereby driving the linkage rod 206 to move in the arc slide groove 207 to make the slide rod 204 slide synchronously in the linear slide groove 203, so that the steel pipe is clamped by the clamping part 205. The clamping force and stability are stronger than those applied by the spring, thereby ensuring stability in use and preventing the steel pipe from being displaced and rotated in the fastening and clamping component 2, which affects the efficiency of seamless steel pipe production and processing.

[0027] It should be noted that the specific models and specifications of the first motor 7 and the second motor 211 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0028] The power supply and principle of the first motor 7 and the second motor 211 are clear to those skilled in the art and will not be described in detail here.

[0029] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
