[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1: As Figures 1 - 4 shown, the present invention provides a honing pipe end processing tooling, including a bracket 21. The inner bottom of the bracket 21 is fixedly connected with a third electric push rod 4. The telescopic end of the third electric push rod 4 is fixedly connected with a mounting frame 41. A rotating shaft 42 is rotatably connected between the inner surfaces of the mounting frame 41. The left surface of the mounting frame 41 is provided with a first motor 43. The output end of the first motor 43 penetrates the left surface of the mounting frame 41 and extends to the right side. The output end of the first motor 43 is fixedly connected with the left end of the rotating shaft 42. First rotating blocks 5 are fixedly connected to positions on the outer surface of the rotating shaft 42 near both sides. The bottom of the first rotating block 5 is fixedly connected with a first hollow shell 51. A second motor 52 is installed inside the first hollow shell 51. The output end of the second motor 52 penetrates the front surface of the first hollow shell 51 and extends to the front side. The output end of the second motor 52 is fixedly connected with a honing bar 53. Second rotating blocks 6 are fixedly connected to positions on the outer surface of the rotating shaft 42 near the middle. The rear surface of the second rotating block 6 is fixedly connected with a second hollow shell 61. A third motor 62 is installed inside the second hollow shell 61. The output end of the third motor 62 penetrates the rear surface of the second hollow shell 61 and extends to the rear side. The output end of the third motor 62 is fixedly connected with a tool 63. The top of the bracket 21 is fixedly connected with a support frame 2. The bottom of the support frame 2 is fixedly connected with an operating table 1. Support legs 11 are fixedly connected to positions near the four corners of the bottom of the operating table 1. First electric push rods 3 are installed on the outer surfaces of both sides of the support frame 2. The telescopic ends of the two first electric push rods 3 are both fixedly connected with U-shaped blocks 31. A second electric push rod 32 is arranged on the top of the U-shaped block 31. The telescopic end of the second electric push rod 32 is fixedly connected with a push plate 33.

[0023] The effect achieved by the entire Embodiment 1 is as follows: When in use, first start the first electric push rods 3 on both sides of the support frame 2. Under the action of the first electric push rods 3, the two U-shaped blocks 31 will move towards each other. When the U-shaped blocks 31 move to a position where they are sufficient to clamp the steel pipe, stop the further advancement of the first electric push rods 3. When adjusting according to different sizes of the steel pipe, the second electric push rods 32 can be started, and the push plates 33 will move downward until they move to a position where the two U-shaped blocks 31 clamp and fix the steel pipe, which is applicable to the processing of steel pipes of different sizes and increases the flexibility of steel pipe fixation. Subsequently, start the third electric push rods 4 on the support legs 21. With the elongation of the third electric push rods 4, the mounting frames 41 move vertically downward, so that the honing bars 53 and the cutting tools 63 on the mounting frames 41 can also move downward synchronously to the preset processing positions. When rough machining of the steel pipe is required, start the first motor 43. Under the action of the first motor 43, the rotating shaft 42 rotates, which will drive the second rotating block 6 to rotate, so that the second hollow shell 61 and the third motor 62 rotate synchronously. The third motor 62 and its cutting tool 63 then rotate downward by 90 degrees to the processing position. Then start the third motor 62 to drive the cutting tool 63 to cut the end face of the steel pipe, which can quickly remove a large amount of redundant material. If fine machining is required, start the first motor 43 again, but this time the rotation drives the first rotating block 5 and its first hollow shell 51 and the second motor 52 thereon. The honing bar 53 then rotates downward by 90 degrees to the processing position. Start the second motor 52, and the honing bar 53 starts to finely hone the end face of the steel pipe. This design avoids the need to replace different cutting tools or grinding wheels during the processing, significantly shortens the processing time, and greatly improves the overall processing efficiency. The support legs 11 play a role in supporting the entire device.

[0024] Embodiment 2: As Figures 1 - 4 shown, rubber pads 34 are provided at the inner bottoms of the two U-shaped blocks 31, and rubber pads 34 are provided at the bottoms of the two push plates 33.

[0025] The effect achieved by the entire Embodiment 2 is that the rubber pads 34 play a buffering role between the clamping blocks and the steel pipe, can absorb the vibration and impact during the processing, prevent the workpiece from moving or deforming due to sudden impact or vibration, and increase the contact area between the clamping blocks and the workpiece, thereby improving the clamping force.

[0026] Working principle: When in use, first start the first electric push rods 3 on both sides of the support frame 2. Under the action of the first electric push rods 3, the two U-shaped blocks 31 will move towards each other. When the U-shaped blocks 31 move to a position where they are sufficient to clamp the steel pipe, stop the further advancement of the first electric push rods 3. When adjusting according to different sizes of the steel pipe, the second electric push rods 32 can be started, and the push plates 33 will move downward until they move to a position where the two U-shaped blocks 31 clamp and fix the steel pipe. It is applicable to the processing of steel pipes of different sizes, increasing the flexibility of steel pipe fixation. Subsequently, start the third electric push rod 4 on the support frame 21. With the elongation of the third electric push rod 4, the mounting frame 41 moves vertically downward, so that the honing bars 53 and the cutting tools 63 on the mounting frame 41 can also move downward synchronously to the preset processing position. When rough machining of the steel pipe is required, start the first motor 43. Under the action of the first motor 43, the rotating shaft 42 rotates, which will drive the second rotating block 6 to rotate, so that the second hollow shell 61 and the third motor 62 rotate synchronously. The third motor 62 and its cutting tool 63 then rotate downward by 90 degrees to the processing position. Then start the third motor 62 to drive the cutting tool 63 to cut the end face of the steel pipe, which can quickly remove a large amount of redundant materials. If fine machining is required, start the first motor 43 again, but this time the rotation drives the first rotating block 5 and its first hollow shell 51 and the second motor 52 on it. The honing bars 53 then rotate downward by 90 degrees to the processing position. Start the second motor 52, and the honing bars 53 start to finely hone the end face of the steel pipe. This design avoids the need to replace different cutting tools or grinding wheels during the processing, significantly shortens the processing time, and greatly improves the overall processing efficiency. Moreover, the rubber pads 34 play a buffering role between the clamping blocks and the steel pipe, can absorb the vibration and impact during the processing, prevent the workpiece from moving or deforming due to sudden impact or vibration, and at the same time increase the contact area between the clamping blocks and the workpiece, thereby improving the clamping force.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
