Description

Technical Field

[0001] The utility model relates to the technical field of threaded pipe processing, in particular to a threaded pipe cutting and deburring device. Background Art

[0002] Threaded pipes, also known as low-rib pipes, are mainly used to expand the heat transfer area by ribs on the outside of the pipe. They are generally used in situations where the heat transfer coefficient inside the pipe is more than 1 times greater than the heat transfer coefficient outside the pipe. During the processing of threaded pipes, a deburring device is required to deburr them. This device usually uses a specific cutting tool or grinding tool to remove burrs by rotating or moving to ensure that the surface of the threaded pipe is smooth and meets quality requirements.

[0003] The prior art discloses a pipeline cut deburring device (publication number: CN220388907U), which includes a clamping assembly, wherein a petroleum pipeline is clamped inside the clamping assembly, and the burrs of the petroleum pipeline are removed by the deburring structure. The petroleum pipeline is placed above two arc-shaped supporting plates, one end of the petroleum pipeline is inserted into the arc-shaped notch, and then the adjusting bolt is screwed backward, at which time the adjusting bolt will drive the square sliding plate to move backward, and since the connecting horizontal plate and the square sliding plate are movably connected by the connecting oblique rod, when the square sliding plate moves backward, the square clamping column will move downward, thereby clamping the petroleum pipeline.

[0004] However, the above technical solution and the prior art still have the following defects: when the device is in use, the end of the pipeline is directly placed on the arc-shaped support plate, and the pipeline is clamped and fixed on the arc-shaped support plate by the clamping column on the upper part, so that one end of the oil pipeline is inserted into the arc-shaped notch. However, when it is necessary to grind and deburr pipelines of different diameters, the center positions of the pipes of different diameters will be different when the device is used to clamp and fix them, resulting in the misalignment of the end of the pipeline and the arc-shaped notch, which makes it impossible to process it, causing great inconvenience to the operator during the operation and processing.

The driving gear 402 is driven by the second servo motor 401 to rotate. During the rotation of the driving gear 402, the rack 404 drives the entire outer ring 403 to rotate, so that the grinding mechanism 9 set on the end of the outer ring 403 rotates with the rotation of the outer ring 403. While the grinding mechanism 9 rotates with the outer ring 403, the end of the threaded pipe after cutting is deburred and polished through its own rotation.

[0030] A mounting seat 7 is provided at the end of the outer ring 403, and a telescopic rod 8 is provided on the mounting seat 7. The output shaft end of the telescopic rod 8 is fixedly connected to the grinding mechanism 9.

[0032] Embodiment 2:

[0033] Based on the first embodiment, the centering clamping mechanism 2 mentioned in the first embodiment is described as follows:

[0034] The centering clamping mechanism 2 includes a first servo motor 201, a worm 202, a turbine 203, a forward and reverse screw 204, a support seat 205 and a slide bar 206.

The worm 202 is transmission-connected to the turbine 203 arranged at the bottom of the forward and reverse screw 204. The top end of the forward and reverse screw 204 is rotatably arranged at the top end of the support seat 205, and slide bars 206 are arranged on both sides of the forward and reverse screw 204.

The clamping block 209 is fixedly connected to the movable slider 207 through the connecting rod 208. The clamping block 209 is used for centering clamping of the threaded pipe.

[0036] In this embodiment, by setting a centering clamping mechanism 2, the threaded pipes with different diameters can be clamped, so that the axis of the threaded pipes with different diameters always remains coaxial with the axis of the through groove 10. The first servo motor 201 is used to drive the positive and negative screw rods 204 through the clamping blocks 209 symmetrically arranged above and below, so that the moving sliders 207 at both ends of the positive and negative screw rods 204 are close to or away from each other, so as to clamp and fix the threaded pipe placed on the lower clamping block 209, thereby ensuring stability during the grinding process.

[0037] Working principle: first, place the end of the threaded pipe to be deburred on the lower clamping block 209, then drive the first servo motor 201 to make the lower clamping block 209 and the upper clamping block 209 approach each other to clamp and fix the threaded pipe therebetween, and the end of the clamped threaded pipe is located at the bottom of the grinding head 904, and then drive the telescopic rod 8 to move the grinding mechanism 9 downward according to the position of the threaded pipe, so that the grinding head 904 contacts the outer side of the end of the threaded pipe, and then drive the second servo motor 401 and the third servo motor 902 at the same time, so that the grinding head 904 rotates to grind the end of the threaded pipe for deburring, and at the same time, through the rotation of the outer ring 403, the grinding head 904 rotates and grinds while rotating along the end of the threaded pipe to grind and remove burrs, and adjust the moving length of the grinding mechanism 9 driven by the telescopic rod 8 according to the diameter of the threaded pipe, so that it is suitable for cutting and deburring threaded pipes of different diameters, thereby improving the applicability and flexibility of the device.
