[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a positioning device for hydraulically clamping steel pipe processing, such as Figure 1-5 As shown, it includes a processing body 1; a fixture 2 arranged on the left side of the processing body 1; and a hydraulic clamping assembly 3 arranged inside the processing body 1; wherein the fixture 2 includes: an arc plate 201 symmetrically arranged inside the fixture 2; a rubber sheet 202 symmetrically arranged on the outside of the arc plate 201, a return spring 203 arranged at the top of the arc plate 201; and a push rod 204 arranged on the upper front side of the arc plate 201; a sliding groove 205 is opened at the front of the interior of the fixture 2.

[0023] It should be noted that, since the existing steel pipe processing devices usually use a fixed clamping device to fix the steel pipe, and during the steel pipe processing process, the device needs to be adapted to steel pipes of different sizes. Therefore, in order to solve the problem that the existing steel pipe processing devices cannot adjust the angle according to steel pipes of different sizes, this solution is provided with a fixture 2 on the left side of the processing body 1, and a connecting rod 4, a connecting shaft 5 and a driving motor 7. After the steel pipe is fixed in the fixture 2, the driving motor 7 drives the fixture 2 to rotate.

[0024] Specifically, in this embodiment, the hydraulic clamping assembly 3 includes a sliding block 301, a connecting rod 302 and a clamping ring 303; a connecting rod 302 arranged on the front side of the sliding block 301; a clamping ring 303 symmetrically arranged on the front side of the connecting rod 302; a rotating rod 304 located in front of the connecting rod 302; a rubber ring 305 arranged inside the clamping ring 303; a fixing bolt 306 symmetrically arranged on the outside of the clamping ring 303; and a fixing rod 307 arranged on the outside of the sliding block 301.

[0025] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the rotating rod 304 is connected through the front side of the connecting rod 302, and the rotating rod 304 is connected through the rear side of the clamping ring 303, the rubber ring 305 is fixedly connected to the clamping ring 303, the fixing bolt 306 is connected through the outside of the clamping ring 303, and the fixing rod 307 is connected through the sliding block 301.

[0026] In this embodiment, when the angle of the steel pipe needs to be adjusted, the steel pipe is first placed into the processing body 1 through the hole on the outside of the processing body 1, and the observation door 13 is opened by the slide rail 12 to operate the internal structure. After the steel pipe is moved to the inside of the placement groove 6, the push rod 204 in the sliding groove 205 can be moved to drive the arc plate 201 and the rubber sheet 202 to move outward, so as to achieve the purpose of placing a larger-sized steel pipe into the device and fixing it. In the process of processing a larger-sized steel pipe, the arc plate 201 is set to the position of the arc plate 202. 201 and the rubber sheet 202 can clamp the steel pipe inside the fixture 2 to prevent the steel pipe from being displaced during processing, and after the steel pipe is taken out, the reset spring 203 will drive the arc plate 201 and the rubber sheet 202 to reset. At the same time, during the processing, when it is necessary to adjust the angle of the steel pipe, the drive motor 7 can be started through the CNC table 14, and the drive motor 7 can be used to drive the connecting shaft 5 and the connecting rod 4 to rotate, and then the connecting rod 4 drives the fixture 2 to rotate synchronously, thereby realizing the adjustment of the angle of the steel pipe, so as to perform full-angle processing operations on the steel pipe.

[0027] In a further preferred embodiment of the present invention, Figure 1-5As shown, a hydraulic table 8 is arranged at the rear of the interior of the processing body 1, a moving groove 9 is opened in the middle of the front side of the hydraulic table 8, and the sliding block 301 and the fixing rod 307 are both located inside the moving groove 9, a processing table 10 is arranged at the front of the interior of the processing body 1, the processing table 10 is located below the hydraulic clamping assembly 3, and the processing table 10 is located on the right side of the fixture 2, a waste trough 11 is opened inside the processing table 10, a slide rail 12 is opened at the lower front side of the processing body 1, an observation door 13 is slidably connected to the front side of the processing body 1, and the bottom end of the observation door 13 is located inside the slide rail 12, and a CNC table 14 is arranged on the right side of the processing body 1.

[0028] In this embodiment, during the processing of steel pipes, the hydraulic clamping assembly 3 set on the hydraulic table 8 can clamp and limit the steel pipes on the outside of the fixer 2, so as to ensure that the steel pipes will not shake accidentally during the processing. During the clamping process, the fixing bolt 306 is first taken out to adjust the clamping ring 303, and then the clamping ring 303 is moved to move it outward, so that the clamping ring 303 drives the rubber ring 305 to rotate through the rotating rod 304, thereby facilitating the placement of the steel pipe to be processed in the clamping ring 303, and the sliding block 301 can be moved so that the sliding block 301 drives the connecting rod 302 to move along the fixed rod 307 in the moving groove 9. During this process, the clamping ring 303 will follow the sliding block 301 to move, thereby achieving the purpose of the clamping ring 303 to clamp and support steel pipes at different positions, and during the processing of the steel pipes, the waste trough 11 on the processing table 10 can collect the waste generated during the processing.
